### 👤 User
I have recently started to refactor the parser into using a BlockParser struct, in order to modularize and improve code structure:
@src/parser/block_dispatcher.rs
Some elements have been migrated, but far from all.
The inspiration for this was to better resemble what pandoc is doing:
@pandoc/src/Text/Pandoc/Readers/Markdown.hs
Now I would like an objective assessment of this approach.
In particular, I am having trouble understanding the point of can_parse(). Is there any? It appears that it if often calling try_parse_* functions, which are then also called in parse(), which seems wasteful to me, potentially hampering performance too.
The previous implemention was in 0ba25b6dd38385f4374f49ee186494a123add433, which was much less structured, and needs a rehaul.
I am wondering if I am on the right track? If my refactoring is correct?

### 💬 Copilot
I’ll inspect the new BlockParser design (especially `can_parse()`), and compare it to the pre-refactor implementation and Pandoc’s approach.

```
1. //! Block parser dispatcher for organizing block-level parsing.
2. //!
3. //! This module provides a trait-based abstraction for block parsers,
4. //! making it easier to add new block types and reducing duplication in parse_inner_content.
5. //!
6. //! Design principles:
7. //! - Single-pass parsing preserved (no backtracking)
8. //! - Each block parser operates independently
9. //! - Inline parsing still integrated (called from within block parsing)
10. //! - Maintains exact CST structure and losslessness

### 💬 Copilot
You’re on the right track: a registry/ordered list of block parsers is basically Pandoc’s `choice [...]` made explicit, and the *main* value of a separate detection phase is letting the caller decide “do I need to flush/close paragraph & list buffers before emitting this block, and can it interrupt?” while keeping precedence/ordering centralized.
That said, in your current code `can_parse()` often isn’t “detection” but “parsing-lite” (calling `try_parse_*` that does real work, plus `SetextHeadingParser::can_parse` allocates a `Vec`, and `core.rs` ends up calling `detect()` multiple times per line in different branches), so you’re right that it’s wasted work and could become a perf footgun.
If you keep the 2-phase API, make `can_parse()` strictly cheap (prefix/first-char checks + minimal lookahead) **or** have it return cached parse data (e.g. `Yes(ParsedFence{...})`, `Yes(level)`) that `parse()` consumes; alternatively, collapse to a single `try_parse(...) -\> Option\<ParsedBlock { can_interrupt, lines_consumed, cached_data }\>` so you still get the “prepare before emit” decision without double-invoking `try_parse_*`.

What do you think is the best option?
1. a single try_parse()
2. The current split, but make can_parse cheap.
3. The current split, but return data from can_parse() (maybe rename it)
4. Another option?
---
<sub>⏱️ 8m 14s</sub>
### 💬 Copilot
Option **3** is the best fit for your architecture: keep the “detect first, then prepare/flush, then emit” flow (which you genuinely need for CST ordering + container buffering), but make detection return a **typed match payload** so you don’t re-run `try_parse_*` in `parse()`.
Concretely: rename `can_parse` to something like `try_match`/`detect`, and have it return `Option\<BlockMatch\>` where `BlockMatch` includes (a) `can_interrupt`/`needs_blank_before` (or a small enum), (b) `lines_consumed` *or* enough data to compute it, and (c) cached parse data (`FenceOpen`, heading level, etc.) that `parse_with_match(...)` uses to emit without re-parsing.
Option 2 works but is fragile (people will “accidentally” call heavy helpers in `can_parse` again), and option 1 only really works if “try_parse” can produce a non-emitting prepared result anyway—in practice that becomes option 3 with a different name.

Will this work with all the various block structs I have? Some are very complicated (not here yet, due to that)
---
<sub>⏱️ 9m 2s</sub>
### 💬 Copilot
Yes, it scales—even for “complicated” blocks—but you’ll likely need to adjust *how* you represent the match payload because you’re using `Vec\<Box\<dyn BlockParser\>\>`.
With trait objects, the practical patterns are: (a) make the registry an `enum BlockParserKind` and return `BlockMatchKind` (also an enum) with parser-specific data, or (b) return `Box\<dyn Any\>`/`Box\<dyn BlockMatch\>` from `detect` and downcast in `parse_with_match` (more boilerplate, less type safety).
For very complex blocks, you can keep the payload minimal (just the discriminating bits and indices) and still avoid the worst double work (e.g., don’t re-scan prefixes / re-parse fence openers / re-do expensive lookahead).

### 👤 User
Why do you prefer this over a single try_parse()?
---
<sub>⏱️ 9m 34s</sub>
### 💬 Copilot
Because you often need to decide “this line starts a block” **before** you emit anything, so the caller can flush list-item buffers / close paragraphs / adjust containers *first* to preserve CST byte order; a single `try_parse()` either (a) emits too early, or (b) must return a prepared result that you apply after preparation.
Once you choose (b), you’ve essentially reinvented “detect returns data” (option 3), just with a different name.
Option 3 makes that intent explicit and prevents the current “detect calls try_parse, parse calls try_parse again” duplication.
---

### 👤 User
But have you really looked at the code? This choice is extremely complicated, and it's not easy to detect up front what to return.
---
<sub>⏱️ 10m 20s</sub>
### 💬 Copilot
I did: in `block_dispatcher.rs` several `can_parse()` implementations already do real parsing work (`try_parse_*`, `InfoString::parse`, fence parsing; setext even allocates a `Vec`), and in `core.rs` you call `detect()` in multiple branches—so today you’re paying that cost repeatedly.
For the complicated blocks, you don’t have to “predict” a rich payload up front: have `detect/try_match` return an **opaque prepared object** produced by the block (e.g. `PreparedBlock` with `kind/can_interrupt` + `emit(&mut builder)` + `lines_consumed()`), so each block decides what to cache internally without forcing a giant shared enum.
That ends up being the best of “single try_parse” and option 3: one parse of the expensive bits, zero emission until the caller prepares, and no requirement that detection be trivially representable.

### 👤 User
Please analyze my code more before coming with a recommendation
---
<sub>⏱️ 10m 53s</sub>
### 💬 Copilot
I’ll inspect how `detect/can_parse/parse` is used in `core.rs` and how expensive the current `can_parse()` implementations are in the migrated blocks.

### 💬 Copilot
In your current migrated blocks, `can_parse()` is already *not* cheap: `FencedCodeBlockParser::can_parse` runs `try_parse_fence_open` **and** `InfoString::parse` (string/alloc-heavy), `SetextHeadingParser::can_parse` allocates a `Vec` and then calls `try_parse_setext_heading`, and `FigureParser::can_parse` calls `try_parse_inline_image` (a real inline parse) — and then several of those blocks re-run the same work again in `parse()` (ATX and fenced definitely do; setext avoids it).
On top of that, `core.rs` calls `block_registry.detect(...)` in multiple branches (blank-before path, interrupt path, and again for refdefs), and it rebuilds `BlockContext` repeatedly; so the cost of “heavy detection” gets multiplied even before you count the duplicate parsing inside each block.
Given *your* code shape, the cleanest fix is: keep the 2-step “detect then prepare then emit”, but make `detect` return a **prepared, parser-owned payload** (possibly opaque) that `parse` consumes (so fenced returns the parsed fence + pre-parsed info-string, setext returns level/underline info, figure returns the image span/validation result, etc.), instead of trying to force `can_parse` to be cheap everywhere.

I’m going to zoom in on `parse_inner_content` in `core.rs` to pinpoint where the dispatcher is invoked redundantly and where a “prepared match” would plug in cleanly.

### 💬 Copilot
In `core.rs`, the dispatcher currently can’t “own” block detection because `parse_inner_content` already does its own heavy “is this a block element?” scan (definition continuation guard at ~1040–1051) using `try_parse_fence_open`, `try_parse_horizontal_rule`, `try_parse_atx_heading`, etc., and then later you call `block_registry.detect(...)` up to **3 times** per line (blank-before path, interrupt path, refdef path) while rebuilding `BlockContext` each time—so right now you have *both* duplicated detection *and* duplicated parsing work inside some block parsers.
Given that structure, the best refactor is: make the registry the single “Pandoc-style `choice`” for *all* block starts (including the “interrupt” case) and have it return a **prepared match** (opaque payload) so `core.rs` can (1) call detect exactly once, (2) decide/perform `prepare_for_block_element` based on `match.can_interrupt/needs_blank_before`, and (3) then emit via `parse_with_match` without re-running `try_parse_*`.
Trying to “make `can_parse` cheap” will fight your current reality (your block detectors already *need* real parsing to disambiguate, e.g. fenced code vs inline/executable, figures using inline image parse), while “prepared match” lets each complicated block cache whatever it needs without forcing `core.rs` to predict a universal return shape.

Wait, what are you concretely suggesting now?

### 💬 Copilot
Concretely:
1) **Stop using `can_parse()` as a boolean probe.** Replace the trait with a single entrypoint that produces a *prepared* result:
```rust
trait BlockParser {
fn try_match(&self, ctx: &BlockContext, lines: &[&str], pos: usize) -\> Option\<BlockMatch\>;
fn name(&self) -\> &'static str;
}
struct BlockMatch {
can_interrupt: bool,
requires_blank_before: bool,
// opaque, parser-specific cached data:
data: Box\<dyn std::any::Any\>,
}
```
and each parser’s `try_match` does the expensive work once and stores what it learned in `data` (e.g. `FenceOpen + InfoString`, heading level, etc.).
2) Add a second method to emit using that cached data (so no re-parsing):
```rust
trait BlockParser {
fn emit(&self, m: &BlockMatch, ctx: &BlockContext, b: &mut GreenNodeBuilder\<'static\>, lines: &[&str], pos: usize) -\> usize;
}
```
Inside `emit`, downcast `m.data` to your parser’s internal type.
3) In `core.rs`, **call registry.detect exactly once per line** (not in 3 branches), then:
- if `m.requires_blank_before` and `!has_blank_before`: ignore match
- else: do `prepare_for_block_element()` iff needed (or `emit_list_item_buffer_if_needed + close_paragraph_if_open` if `can_interrupt`)
- then call `registry.emit(match, ...)`
That’s the concrete change: “detect” returns a prepared, cached parse result, and `core.rs` becomes “one detect → maybe prepare → emit”, eliminating the current double work and the repeated `detect()` calls.

Should I revert and restart or continue from the current state?
---
<sub>⏱️ 14m 32s</sub>
### 💬 Copilot
Continue from the current state; you already have the registry ordering and several migrated blocks, so reverting would just throw away useful structure.
Do it incrementally: introduce the “prepared match” API alongside the current `can_parse/parse`, convert one migrated parser first (fenced code is the biggest win), then adjust `core.rs` to call detect once and to use the cached match for emit, and only then migrate the remaining blocks.
Only consider a revert if you feel `core.rs` has become unmaintainable mid-transition—but right now it’s still a straightforward evolution path.

Key points: proceed from current state, add a “prepared match” detection API (trait objects + opaque payload), convert the already-migrated parsers to cache expensive work, then refactor `core.rs` to do **one** detect per line and remove the duplicated “is_block_element” probing by delegating to the registry.

### 💬 Copilot
Implemented the first step of the “prepared match” refactor (low-churn path):
- Added `PreparedBlockMatch` + `detect_prepared()` + `parse_prepared()` to `BlockParserRegistry`.
- Extended `BlockParser` with default `detect_prepared()` / `parse_prepared()` hooks (backwards compatible).
- Converted **FencedCodeBlockParser** to cache `FenceInfo` (and avoid re-parsing the fence in `parse_prepared`), with a safe fallback for legacy `parse()` calls.
- Updated `core.rs` callsites that used the dispatcher to use `detect_prepared`/`parse_prepared`.
- All tests pass (`cargo test -q`).
Next step is converting ATX heading (cache level), then reference definitions (cache parsed tuple), then setext (cache level/underline and remove Vec alloc), and finally removing the duplicated `is_block_element` probe by delegating to the registry.

```
1. # Plan: Block dispatcher “prepared match” refactor
2.
3. ## Problem
4. Current `BlockParser::can_parse()` often does non-trivial work (e.g. fenced code parses fence + `InfoString::parse`, setext allocates, figure uses inline image parsing). This work is frequently repeated because:
5. - several parsers call `try_parse_*` again inside `parse()`
6. - `core.rs` calls `block_registry.detect(...)` multiple times per line in different branches
7. - `core.rs` separately re-implements “is this a block element marker?” checks (e.g. Definition continuation guard), further duplicating detection.
8.
9. ## Goal
10. Keep the good part of the refactor (Pandoc-like ordered registry + ability to “prepare/flush buffers before emitting”), while eliminating duplicate detection/parsing and reducing `core.rs` complexity.
11.
12. ## Approach (high level)
13. Introduce a **prepared match** concept: detection returns a match object that caches any expensive parsing results, and emission consumes that cached data (no re-parsing). Then rework `core.rs` so each line does **one** detection pass, decides whether the match is allowed (blank-line rules / interrupt rules), performs preparation, and emits.
14.
15. ## Key design decision (to confirm)
16. Two viable representations:
17. 1) **Trait objects + opaque payload** (recommended for minimal churn): registry remains `Vec<Box<dyn BlockParser>>`. Detection returns a `BlockMatch` containing a parser index + interrupt/blank requirements + `Box<dyn Any>` payload; emission downcasts payload.
18. 2) **Enum registry + typed payload** (slightly faster/cleaner types, but larger refactor): registry becomes `Vec<BlockParserKind>` and match payload becomes an enum.
19.
20. ## Workplan
21.
22. ### A. Baseline & safety
23. - [ ] Run baseline tests/benchmarks to capture current behavior (`cargo test` at minimum).
24. - [ ] Identify a small set of “high-signal” golden cases to watch while refactoring (fenced code, setext, yaml/hrule ambiguity, refdefs).
25.
26. ### B. Introduce prepared-match API (non-invasive)
27. - [ ] Add new types in `src/parser/block_dispatcher.rs`:
28. - `BlockMatch` (contains: `kind`/parser index, `can_interrupt`, `requires_blank_before`, and cached payload)
29. - `DetectOutcome` if needed (e.g. `No | Match(BlockMatch)`)
30. - [ ] Extend `BlockParserRegistry` with new entrypoints (keep old API temporarily):
31. - `detect_prepared(...) -> Option<BlockMatch>`
32. - `emit_prepared(match, ...) -> usize`
33.
34. ### C. Convert migrated parsers (start with biggest perf win)
35. - [ ] Fenced code: `try_match` parses fence + `InfoString` once; `emit` reuses cached fence/info.
36. - [ ] ATX heading: `try_match` returns cached level; `emit` uses it (no second `try_parse_atx_heading`).
37. - [ ] YAML: `try_match` validates opening and maybe caches “is yaml not hrule”; `emit` calls existing `try_parse_yaml_block` or reuses cached facts.
38. - [ ] Figure: `try_match` caches validation span from inline image parse so it isn’t repeated.
39. - [ ] Setext: remove allocation in detection (no `Vec`); cache `(level, underline_char)`.
40. - [ ] Reference definition: cache parse tuple from `try_parse_reference_definition`.
41.
42. ### D. Refactor `core.rs` to “single detect per line”
43. - [ ] Create one `BlockContext` per line and reuse it (avoid repeated rebuilds).
44. - [ ] Replace the multiple `block_registry.detect(...)` calls (~3 sites) with one flow:
45. - detect once
46. - check `requires_blank_before` vs computed blank condition
47. - if `can_interrupt`: flush list item buffer + close paragraph
48. - else: `prepare_for_block_element()`
49. - emit using prepared match
50. - [ ] Rework the Definition continuation guard (`is_block_element` at ~1041): instead of calling many `try_parse_*` helpers, use the registry’s prepared detection (or a dedicated “block start probe” function that calls into the registry) so you don’t duplicate marker logic.
51.
52. ### E. Consolidate ordering/precedence in the registry
53. - [ ] Move remaining “block start” checks from `core.rs` into the registry progressively (tables/divs/html/latex/etc.), keeping Pandoc ordering notes.
54. - [ ] Ensure special-case precedence rules stay correct (e.g., YAML vs hrule, setext vs hrule, list vs header edge cases).
55.
56. ### F. Cleanup
57. - [ ] Remove old `can_parse/parse` API once all migrated blocks use prepared matches.
58. - [ ] Remove redundant detection logic left in `core.rs`.
59. - [ ] Run full test suite + clippy + fmt check.
60.
61. ## Notes / Constraints
62. - Maintain single-pass, lossless CST emission; prepared matches must not emit to the builder.
63. - Prepared payload should avoid borrowing `ctx.content` directly unless lifetimes are carefully managed; prefer storing indices / owned small strings only when needed.
64. - Performance expectation: dynamic dispatch/downcast overhead is negligible vs string scanning/allocs; eliminating repeated `InfoString::parse` etc. is the main win.
65.

### 💬 Copilot
I’m going to (1) update the session plan with completed items, (2) migrate ATX + refdef + setext to prepared payloads, and (3) remove the last legacy `parse()` callsites in `core.rs`, then run tests.

I’ll migrate ATX/setext/refdef to prepared payloads and finish swapping remaining `core.rs` legacy `parse()` calls, then run the full test suite.

2. //!
3. //! This module provides a trait-based abstraction for block parsers,
4. //! making it easier to add new block types and reducing duplication in parse_inner_content.
5. //!
6. //! Design principles:
7. //! - Single-pass parsing preserved (no backtracking)
8. //! - Each block parser operates independently
9. //! - Inline parsing still integrated (called from within block parsing)
10. //! - Maintains exact CST structure and losslessness

I’ll now (1) switch the remaining core dispatcher callsites to `parse_prepared`, and (2) migrate ATX + improve setext detection to avoid duplicate parsing/allocation, then run `cargo test -q` and update plan.md.

### 💬 Copilot
Kept going: converted **ATX headings** to use `detect_prepared()` with cached level payload (and `parse_prepared()` uses it), removed the `Vec` allocation in **setext detection** (now uses `[&str; 2]`), and updated the remaining `core.rs` dispatcher callsites to use `detect_prepared()` + `parse_prepared()` (no more `parser_idx` plumbing). `cargo test -q` is green; plan.md is updated to reflect progress and next steps. Next up is doing the same payload-caching for **reference definitions** (and optionally YAML/figure), then tackling the bigger `core.rs` “single detect per line” consolidation.

Still no second thoughts about the architecture? If not, keep going

### 💬 Copilot
I’ll sanity-check the current “prepared match + payload” architecture quickly (main risks: Any downcast safety + lifetime/borrow boundaries), then continue by migrating reference definitions (prepared payload) and updating plan.md.

<details>
<summary>39 lines</summary>
```
20. ## Workplan
21.
22. ### A. Baseline & safety
23. - [x] Run baseline tests/benchmarks to capture current behavior (`cargo test` at minimum).
24. - [ ] Identify a small set of “high-signal” golden cases to watch while refactoring (fenced code, setext, yaml/hrule ambiguity, refdefs).
25.
26. ### B. Introduce prepared-match API (non-invasive)
27. - [x] Add new types in `src/parser/block_dispatcher.rs`:
28. - `PreparedBlockMatch` (parser index + detection + cached payload)
29. - [x] Extend `BlockParserRegistry` with new entrypoints (keep old API temporarily):
30. - `detect_prepared(...) -> Option<PreparedBlockMatch>`
31. - `parse_prepared(match, ...) -> usize`
32.
33. ### C. Convert migrated parsers (start with biggest perf win)
34. - [x] Fenced code: detection parses fence + `InfoString` once; parse reuses cached `FenceInfo`.
35. - [x] ATX heading: detection returns cached level; parse uses it (no second `try_parse_atx_heading`).
36. - [ ] YAML: optionally cache “is yaml not hrule” disambiguation.
37. - [ ] Figure: cache validation span from inline image parse so it isn’t repeated.
38. - [x] Setext: remove allocation in detection (no `Vec`).
39. - [ ] Reference definition: optionally cache parse tuple from `try_parse_reference_definition`.
40.
41. ### D. Refactor `core.rs` to “single detect per line”
42. - [ ] Create one `BlockContext` per line and reuse it (avoid repeated rebuilds).
43. - [ ] Replace the multiple dispatcher detections with one flow per line (detect once, then prepare/emit).
44. - [ ] Rework the Definition continuation guard (`is_block_element` at ~1041) to delegate to the registry instead of duplicating `try_parse_*` checks.
45.
46. ### E. Consolidate ordering/precedence in the registry
47. - [ ] Move remaining “block start” checks from `core.rs` into the registry progressively (tables/divs/html/latex/etc.), keeping Pandoc ordering notes.
48. - [ ] Ensure special-case precedence rules stay correct (e.g., YAML vs hrule, setext vs hrule, list vs header edge cases).
49.
50. ### F. Cleanup
51. - [ ] Remove old `can_parse/parse` API once all migrated blocks use prepared matches.
52. - [ ] Remove redundant detection logic left in `core.rs`.
53. - [ ] Run full test suite + clippy + fmt check.
54.
55. ## Notes / Constraints
56. - Maintain single-pass, lossless CST emission; prepared matches must not emit to the builder.
57. - Prepared payload should avoid borrowing `ctx.content` directly unless lifetimes are carefully managed; prefer storing indices / owned small strings only when needed.
58. - Performance expectation: dynamic dispatch/downcast overhead is negligible vs string scanning/allocs; eliminating repeated `InfoString::parse` etc. is the main win.

39:- [x] Reference definition: cache parse tuple from `try_parse_reference_definition` (payload currently unused by emitter).
```

### 💬 Copilot
No second thoughts yet—the **prepared match** architecture still looks like the right “Pandoc-like, single-pass, no backtracking” compromise: it keeps ordering explicit, lets `core.rs` flush/close containers before emission, and eliminates the big duplication/perf cliff from `can_parse()` doing real work twice.
Kept going:
- Migrated **ReferenceDefinitionParser** to `detect_prepared()` and cached the full `try_parse_reference_definition(...)` tuple in the payload (emitter still only uses the original line today, but now we won’t re-run the parser later when we do richer emission).
- Updated **plan.md** to mark this step done.
- `cargo test -q` passes.
Next concrete step is the bigger win: refactor `core.rs` to do **one dispatcher detect per line** (instead of multiple detect/contexts), and then route the Definition continuation “is_block_element” probe through the registry.

okay, let's do it

### 💬 Copilot
I’m going to refactor `core.rs` to compute the dispatcher match once per line and reuse it across the blank-before, interrupt, and refdef sections, keeping refdef behavior unchanged.

1. //! Block parser dispatcher for organizing block-level parsing.
2. //!
3. //! This module provides a trait-based abstraction for block parsers,
4. //! making it easier to add new block types and reducing duplication in parse_inner_content.
5. //!
6. //! Design principles:
7. //! - Single-pass parsing preserved (no backtracking)
8. //! - Each block parser operates independently
9. //! - Inline parsing still integrated (called from within block parsing)
10. //! - Maintains exact CST structure and losslessness

1. # Plan: Block dispatcher “prepared match” refactor
2.
3. ## Problem
4. Current `BlockParser::can_parse()` often does non-trivial work (e.g. fenced code parses fence + `InfoString::parse`, setext allocates, figure uses inline image parsing). This work is frequently repeated because:
5. - several parsers call `try_parse_*` again inside `parse()`
6. - `core.rs` calls `block_registry.detect(...)` multiple times per line in different branches
7. - `core.rs` separately re-implements “is this a block element marker?” checks (e.g. Definition continuation guard), further duplicating detection.
8.
9. ## Goal
10. Keep the good part of the refactor (Pandoc-like ordered registry + ability to “prepare/flush buffers before emitting”), while eliminating duplicate detection/parsing and reducing `core.rs` complexity.
11.
12. ## Approach (high level)
13. Introduce a **prepared match** concept: detection returns a match object that caches any expensive parsing results, and emission consumes that cached data (no re-parsing). Then rework `core.rs` so each line does **one** detection pass, decides whether the match is allowed (blank-line rules / interrupt rules), performs preparation, and emits.
14.
15. ## Key design decision (to confirm)
16. Two viable representations:
17. 1) **Trait objects + opaque payload** (recommended for minimal churn): registry remains `Vec<Box<dyn BlockParser>>`. Detection returns a `BlockMatch` containing a parser index + interrupt/blank requirements + `Box<dyn Any>` payload; emission downcasts payload.
18. 2) **Enum registry + typed payload** (slightly faster/cleaner types, but larger refactor): registry becomes `Vec<BlockParserKind>` and match payload becomes an enum.
19.
20. ## Workplan
21.
22. ### A. Baseline & safety
23. - [x] Run baseline tests/benchmarks to capture current behavior (`cargo test` at minimum).
24. - [ ] Identify a small set of “high-signal” golden cases to watch while refactoring (fenced code, setext, yaml/hrule ambiguity, refdefs).
25.
26. ### B. Introduce prepared-match API (non-invasive)
27. - [x] Add new types in `src/parser/block_dispatcher.rs`:
28. - `PreparedBlockMatch` (parser index + detection + cached payload)
29. - [x] Extend `BlockParserRegistry` with new entrypoints (keep old API temporarily):
30. - `detect_prepared(...) -> Option<PreparedBlockMatch>`
31. - `parse_prepared(match, ...) -> usize`
32.
33. ### C. Convert migrated parsers (start with biggest perf win)
34. - [x] Fenced code: detection parses fence + `InfoString` once; parse reuses cached `FenceInfo`.
35. - [x] ATX heading: detection returns cached level; parse uses it (no second `try_parse_atx_heading`).
36. - [ ] YAML: optionally cache “is yaml not hrule” disambiguation.
37. - [ ] Figure: cache validation span from inline image parse so it isn’t repeated.
38. - [x] Setext: remove allocation in detection (no `Vec`).
39. - [x] Reference definition: cache parse tuple from `try_parse_reference_definition` (payload currently unused by emitter).
40.
41. ### D. Refactor `core.rs` to “single detect per line”
42. - [ ] Create one `BlockContext` per line and reuse it (avoid repeated rebuilds).
43. - [x] Replace the multiple dispatcher detections with one flow per line (detect once, then prepare/emit).
44. - [x] Rework the Definition continuation guard (`is_block_element` at ~1041) to delegate to the registry for migrated blocks (keeps special-cases for def/list/bq/html/tex).
45.
46. ### E. Consolidate ordering/precedence in the registry
47. - [ ] Move remaining “block start” checks from `core.rs` into the registry progressively (tables/divs/html/latex/etc.), keeping Pandoc ordering notes.
48. - [ ] Ensure special-case precedence rules stay correct (e.g., YAML vs hrule, setext vs hrule, list vs header edge cases).
49.
50. ### F. Cleanup
51. - [ ] Remove old `can_parse/parse` API once all migrated blocks use prepared matches.
52. - [ ] Remove redundant detection logic left in `core.rs`.
53. - [ ] Run full test suite + clippy + fmt check.
54.
55. ## Notes / Constraints
56. - Maintain single-pass, lossless CST emission; prepared matches must not emit to the builder.
57. - Prepared payload should avoid borrowing `ctx.content` directly unless lifetimes are carefully managed; prefer storing indices / owned small strings only when needed.
58. - Performance expectation: dynamic dispatch/downcast overhead is negligible vs string scanning/allocs; eliminating repeated `InfoString::parse` etc. is the main win.

### 💬 Copilot
Got it working again and kept the “single detect per line” architecture intact.
- Fixed the `parse_prepared` call to pass the `PreparedBlockMatch` by value (it was accidentally being passed by `&` in one branch).
- Restored correct precedence for footnotes over dispatcher-based reference definitions by explicitly nulling `dispatcher_match` when `try_parse_footnote_marker(content)` matches.
- Resolved the borrow-checker failures by removing `&self.containers` from `BlockContext` (it created a long-lived immutable borrow that prevented `prepare_for_block_element()` / container mutations); tests now pass.
Validation: `cargo test -q` is green (all suites passing).

### 💬 Copilot
Next chunk done: I pushed more “is this nested block structure?” logic through the registry so `core.rs` keeps shrinking.
- In `compute_levels_to_keep()` (Definition continuation after blank lines), I removed the hardcoded `try_parse_fence_open` / `try_parse_div_fence_open` / `try_parse_horizontal_rule` checks and replaced them with a registry `detect_prepared(...)` probe.
- Cleaned up now-unused imports in `core.rs`.
- `cargo test -q` still fully green.
Want me to do the next obvious win: switch that probe to a small dedicated `BlockContext` helper (so we don’t rebuild it inline), or start migrating another complicated block into prepared payloads (YAML disambiguation or Figure caching)?

Do the next obvious win

### 💬 Copilot
I’ll factor the repeated “registry probe for nested block structure” into a small helper on `Parser` and reuse it, keeping behavior identical and tests green.

### 💬 Copilot
Extracted the inline registry probe in `compute_levels_to_keep()` into a dedicated helper `Parser::has_nested_block_structure(&self, content: &str)`, so the Definition continuation logic is now much cleaner and reusable. `cargo test -q` is still fully green.

### 💬 Copilot
Kept going and took the next high-impact win: **Figure detection is now “prepared” and caches the expensive inline-image validation**.
- `FigureParser` now implements `detect_prepared()` using `try_parse_inline_image(...)` once, and returns a payload (currently the parsed length) so we don’t re-validate later.
- Removed the now-unused `try_parse_figure()` helper (and its tests) from `src/parser/blocks/figures.rs` to avoid dead code.
- `cargo test -q` is green (now 837 tests in that first suite, because those removed unit tests were part of it).
Next obvious win after this: do the same prepared caching for **YAML metadata disambiguation** (avoid re-checking and make the YAML-vs-hrule decision a cached payload).

### 💬 Copilot
Done: `YamlMetadataParser` now uses the prepared API so YAML-vs-hrule disambiguation (the “next line must not be blank” lookahead) only happens once.
- Implemented `detect_prepared()` for YAML and cached `at_document_start` as payload.
- Switched `parse()` to delegate to `parse_prepared()` and read the cached flag.
- `cargo test -q` is green.
Next best target is similar: **reference definitions** (we’re already caching the tuple, but emission still ignores it), or **div fences** (they tend to do non-trivial scanning).

I’m going to keep reference definitions using the existing CST shape (so golden CST snapshots don’t churn), but ensure emission never re-parses when we already have the cached tuple.

<sub>⏱️ 93m 19s</sub>
### 💬 Copilot
Done for reference definitions (without changing CST shape).
- `ReferenceDefinitionParser::detect_prepared()` already caches the parsed tuple from `try_parse_reference_definition(...)`; I made `parse_prepared()` *actually rely on that* by adding a `debug_assert!` that the payload is present (so we don’t silently regress to re-parsing later).
- Emission stays via the existing `emit_reference_definition_content(...)`, which matches your current golden CST (LINK node + trailing TEXT), so we don’t break `tests/cases/reference_links/*` snapshots.
- `cargo test -q` is green.
If you want the *next* step for refdefs, we can add an internal “fully-structured refdef emission” behind a flag and update the golden CSTs intentionally—but that’s a semantic tree change, not just a perf/duplication win.

### 💬 Copilot
Yep — that `block_dispatcher.rs :L726-L788` Setext parser is the right next target, and there’s a concrete bug there: it uses `ctx.next_line` but in `core.rs` we were previously passing the *raw* next line (including `\>` markers), while `ctx.content` is *already stripped to inner content*. That means setext detection could silently fail inside blockquotes because `try_parse_setext_heading([ctx.content, next_line])` sees a `\>`-prefixed underline line.
I fixed this by making `core.rs` pass `ctx.next_line` as `count_blockquote_markers(next_line).1` (inner content), so lookahead-based blocks operate on the same representation as `ctx.content`; tests are green (`cargo test -q`). I also wired `PandocTitleBlockParser` into the registry ordering and removed the now-redundant direct title-block parse in `core.rs`.

great! let's continue

### 💬 Copilot
I’ll find where `dispatcher_match` is consumed in `core.rs` and identify the next block type we can safely migrate (ideally one that doesn’t mutate container stack, like HTML blocks or LaTeX envs).

### 👤 User
Wait, you're adding new blocks now? Shouldn't we first remove the can_parse and parse stuff, or is there any reason we still need it? Maybe I missed something?
---

### 💬 Copilot
Yes—we’re adding new *registry* blocks as part of migrating logic out of `core.rs`; that’s the “next obvious win” because it shrinks `core.rs` and keeps precedence centralized.
On `can_parse`/`parse`: they’re not strictly necessary for the *prepared* path (`detect_prepared`/`parse_prepared`), but they currently serve as (1) cheap/default implementations for simple parsers (so you don’t have to implement both prepared hooks everywhere), and (2) compatibility for any remaining callsites/tests/utilities that still use the non-prepared `detect()`/`parse()` path (even if most of `core.rs` now uses prepared).
Once more blocks are migrated and we confirm nothing relies on `detect()`/`can_parse()` anymore, we can simplify the trait to “prepared-only” (or keep `can_parse` as a purely-cheap probe and forbid calling expensive `try_parse_*` from it).

### 💬 Copilot
You’re right to flag this: fenced divs can’t be safely migrated into the dispatcher yet because they must mutate the container stack, and the current `BlockParser` interface doesn’t allow that. I’m going to revert the fenced-div dispatcher work (and the `in_fenced_div` context field) and keep the HTML/LaTeX/line-block migrations.

### 💬 Copilot
HTML/LaTeX/line block are now migrated into the dispatcher and `core.rs` no longer parses HTML/LaTeX blocks directly; tests are green.
On fenced divs: I started migrating them too, but hit the key architectural issue—we can’t fully move fenced divs into the dispatcher cleanly until the dispatcher has a way to interact with the container stack (open needs to `push(Container::FencedDiv)` and close needs to pop/finish it). I reverted the dispatcher-side fenced-div attempt and restored the original fenced-div parsing in `core.rs`, so behavior is unchanged and we can discuss the right integration approach next.

1. # Plan: Block dispatcher “prepared match” refactor
2.
3. ## Problem
4. Current `BlockParser::can_parse()` often does non-trivial work (e.g. fenced code parses fence + `InfoString::parse`, setext allocates, figure uses inline image parsing). This work is frequently repeated because:
5. - several parsers call `try_parse_*` again inside `parse()`
6. - `core.rs` calls `block_registry.detect(...)` multiple times per line in different branches
7. - `core.rs` separately re-implements “is this a block element marker?” checks (e.g. Definition continuation guard), further duplicating detection.
8.
9. ## Goal
10. Keep the good part of the refactor (Pandoc-like ordered registry + ability to “prepare/flush buffers before emitting”), while eliminating duplicate detection/parsing and reducing `core.rs` complexity.
11.
12. ## Approach (high level)
13. Introduce a **prepared match** concept: detection returns a match object that caches any expensive parsing results, and emission consumes that cached data (no re-parsing). Then rework `core.rs` so each line does **one** detection pass, decides whether the match is allowed (blank-line rules / interrupt rules), performs preparation, and emits.
14.
15. ## Key design decision (to confirm)
16. Two viable representations:
17. 1) **Trait objects + opaque payload** (recommended for minimal churn): registry remains `Vec<Box<dyn BlockParser>>`. Detection returns a `BlockMatch` containing a parser index + interrupt/blank requirements + `Box<dyn Any>` payload; emission downcasts payload.
18. 2) **Enum registry + typed payload** (slightly faster/cleaner types, but larger refactor): registry becomes `Vec<BlockParserKind>` and match payload becomes an enum.
19.
20. ## Workplan
21.
22. ### A. Baseline & safety
23. - [x] Run baseline tests/benchmarks to capture current behavior (`cargo test` at minimum).
24. - [ ] Identify a small set of “high-signal” golden cases to watch while refactoring (fenced code, setext, yaml/hrule ambiguity, refdefs).
25.
26. ### B. Introduce prepared-match API (non-invasive)
27. - [x] Add new types in `src/parser/block_dispatcher.rs`:
28. - `PreparedBlockMatch` (parser index + detection + cached payload)
29. - [x] Extend `BlockParserRegistry` with new entrypoints (keep old API temporarily):
30. - `detect_prepared(...) -> Option<PreparedBlockMatch>`
31. - `parse_prepared(match, ...) -> usize`
32.
33. ### C. Convert migrated parsers (start with biggest perf win)
34. - [x] Fenced code: detection parses fence + `InfoString` once; parse reuses cached `FenceInfo`.
35. - [x] ATX heading: detection returns cached level; parse uses it (no second `try_parse_atx_heading`).
36. - [ ] YAML: optionally cache “is yaml not hrule” disambiguation.
37. - [ ] Figure: cache validation span from inline image parse so it isn’t repeated.
38. - [x] Setext: remove allocation in detection (no `Vec`).
39. - [x] Reference definition: cache parse tuple from `try_parse_reference_definition` (payload currently unused by emitter).
40.
41. ### D. Refactor `core.rs` to “single detect per line”
42. - [x] Create one `BlockContext` per line and reuse it (avoid repeated rebuilds).
43. - [x] Replace the multiple dispatcher detections with one flow per line (detect once, then prepare/emit).
44. - [x] Rework the Definition continuation guard (`is_block_element` at ~1041) to delegate to the registry for migrated blocks (keeps special-cases for def/list/bq/html/tex).
45. - [x] Delegate nested-block marker probes (Definition continuation after blank line) to the registry instead of hardcoding fence/div/hrule checks.
46.
47. Notes:
48. - `BlockContext` no longer stores `&ContainerStack` to avoid long-lived borrows blocking mutation during preparation/emission.
49.
50. ### E. Consolidate ordering/precedence in the registry
51. - [ ] Move remaining “block start” checks from `core.rs` into the registry progressively (tables/divs/html/latex/etc.), keeping Pandoc ordering notes.
52. - [ ] Ensure special-case precedence rules stay correct (e.g., YAML vs hrule, setext vs hrule, list vs header edge cases).
53.
54. ### F. Cleanup
55. - [ ] Remove old `can_parse/parse` API once all migrated blocks use prepared matches.
56. - [ ] Remove redundant detection logic left in `core.rs`.
57. - [ ] Run full test suite + clippy + fmt check.
58.
59. ## Notes / Constraints
60. - Maintain single-pass, lossless CST emission; prepared matches must not emit to the builder.
61. - Prepared payload should avoid borrowing `ctx.content` directly unless lifetimes are carefully managed; prefer storing indices / owned small strings only when needed.
62. - Performance expectation: dynamic dispatch/downcast overhead is negligible vs string scanning/allocs; eliminating repeated `InfoString::parse` etc. is the main win.

### 💬 Copilot
Options for fenced div integration (given the container-stack dependency) boil down to **who owns container mutations**:
1) **“Dispatcher emits, core mutates containers” (recommended, minimal change)**
- Add a tiny “side-effect” signal to the prepared match, e.g. `PreparedBlockMatch { kind: ContainerEffect::OpenFencedDiv | CloseFencedDiv | None, … }`.
- Dispatcher **only emits CST nodes** for `DIV_FENCE_OPEN` / `DIV_FENCE_CLOSE` (and starts `FENCED_DIV`), but `core.rs` performs `containers.push(Container::FencedDiv)` / `close_containers_to(...)` around the dispatcher emission.
- Pros: preserves current ownership model (only `core` touches `containers`), avoids borrow/lifetime traps, keeps BlockContext simple.
- Cons: fenced-div handling remains “split brain” (some logic in dispatcher, some in core), but it’s a clean split.
2) **Pass a `ContainerSink`/callback into `parse_prepared`**
- Extend `parse_prepared(..., hooks: &mut dyn BlockParseHooks)` where hooks has methods like `open_fenced_div()` / `close_fenced_div()`.
- `core.rs` provides the implementation that mutates `self.containers`; dispatcher stays generic.
- Pros: keeps fenced-div logic “inside the fenced-div parser” (more modular).
- Cons: introduces a new interface threaded through registry; slightly more moving parts.
3) **Let block parsers mutate containers directly**
- Make `parse_prepared` take `&mut Parser` (or `&mut ContainerStack`) instead of just builder/lines.
- Pros: simplest inside the parser.
- Cons: reintroduces the borrow-checker problems you already hit (long-lived borrows / tight coupling), and makes the dispatcher much less reusable/testable.
4) **Don’t migrate fenced divs yet (status quo)**
- Keep them in `core.rs` until we have a more general “container-aware block parser” design for other containerized blocks too (lists/footnotes/definition lists).
- Pros: zero risk.
- Cons: fenced div remains a big chunk in `core.rs`.
I updated `plan.md` to mark HTML/LaTeX/line-block as done and to add a fenced-div decision item; next step would be implementing option (1) or (2).

### 💬 Copilot
Yes—the “container” approach is broadly correct for *us*, and Pandoc does something very similar conceptually, just expressed differently because it’s a monadic parser with mutable reader state rather than a CST builder + explicit stack.
Pandoc’s approach in `Markdown.hs`:
- It keeps **reader state flags/counters** that influence block parsing across lines (notably `stateFencedDivLevel`, and also `stateInHtmlBlock`, `stateParserContext`, etc.).
- For fenced divs specifically, it does **not** build a generic “container stack”; it increments/decrements a **fenced div nesting counter** around parsing the div body:
- On open (`divFenced`): `stateFencedDivLevel += 1`, then parses blocks until `divFenceEnd`, then `stateFencedDivLevel -= 1`.
- That state is then consulted in other places to adjust “blankline” / continuation behavior (e.g. `blanklines'`, `notFollowedByDivCloser`, list continuation checks).
How this maps to Panache:
- Your `ContainerStack` is effectively a *structured* version of Pandoc’s reader state: instead of “just counters/flags”, you track nested constructs (BlockQuote/ListItem/Paragraph/FencedDiv) and buffer content accordingly.
- That’s a good fit for a lossless CST builder because you need explicit open/close points and buffering anyway; Pandoc can “just parse into an AST” and rely on parser combinator backtracking + state.
So the issue you hit with fenced divs isn’t that containers are wrong—it’s that **Pandoc treats fenced div as a stateful block**, and in Panache that state currently lives in `core.rs` (`ContainerStack`). To migrate fenced divs cleanly, the dispatcher needs a way to trigger a small state transition (push/pop / level inc-dec), analogous to Pandoc’s `stateFencedDivLevel` updates.

### 👤 User
If we go with the first option, what you recommended, can we eventually switch once we move everything into the dispatcher? Or does it have to stay outside in core? Maybe it's fine that it's there, I don't really know.

### 💬 Copilot
Yes—you can switch later: option (1) is a good **bridge** because it keeps container mutations centralized while you migrate block detection/emission into the dispatcher. As migration completes, `core.rs` can shrink into a thin “executor” that just loops lines, calls the dispatcher, and applies returned **effects** (push/pop/close/flush) + emits nodes—at that point the “real parser” is effectively the dispatcher even if the loop still lives in `core`. It’s also totally fine if a tiny bit stays in `core` permanently, because something must own the single-pass loop + container lifecycle; the key is that it becomes generic plumbing, not a pile of block-specific branches.

### 👤 User
Okay, let's go with option 1 then
---
<sub>⏱️ 125m 2s</sub>
### 💬 Copilot
Implementing option 1 by adding a minimal “container effect” from dispatcher for fenced div open/close, with core applying the container-stack mutations.

1. //! Block parser dispatcher for organizing block-level parsing.
2. //!
3. //! This module provides a trait-based abstraction for block parsers,
4. //! making it easier to add new block types and reducing duplication in parse_inner_content.
5. //!
6. //! Design principles:
7. //! - Single-pass parsing preserved (no backtracking)
8. //! - Each block parser operates independently
9. //! - Inline parsing still integrated (called from within block parsing)
10. //! - Maintains exact CST structure and losslessness

### 💬 Copilot
Implemented **option 1** for fenced divs: the dispatcher now detects/emits `DIV_FENCE_OPEN`/`DIV_FENCE_CLOSE` and returns a `BlockEffect` (`OpenFencedDiv`/`CloseFencedDiv`), while `core.rs` remains the sole owner of container mutations (push/pop/close).
Changes:
- `block_dispatcher.rs`: added `BlockEffect`, `PreparedBlockMatch.effect`, `BlockContext.in_fenced_div`, plus `FencedDivOpenParser` and `FencedDivCloseParser` wired into registry order.
- `core.rs`: passes `in_fenced_div` into dispatcher context, applies `block_match.effect` after emission, and removed the old inline fenced-div branches.
Validation: `cargo test -q` passes (including golden `fenced_divs`).

Moving indented code blocks into the dispatcher next (it’s stateless aside from indentation + blockquote depth) and wiring a strict-blank-line flag through BlockContext to preserve current behavior.

1. # PLAIN Continuation Edge Cases
2.
3. ## Multi-line Definition
4.
5. Term 1
6. : First line of definition
7. continues here with proper indent
8. and even a third line.
9.
10. Term 2
11. : Single line definition.
12.
13. ## Definition with Blank Lines
14.
15. Term with blank
16. : Definition starts here
17.
18. Continues after blank line
19. with more content.
20.
21. ## Definition Followed by Nested List
22.
23. Term before list
24. : Definition content here
25. continues on next line
26.
27. - Nested list inside definition
28. - Second item
29.
30. ## Definition with Inline Markup
31.
32. **Bold term**
33. : Definition with *emphasis* and **bold**
34. continues with `code` on next line
35. and [link](http://example.com) here.
36.
37. ## Definition Followed by Blockquote
38.
39. Regular term
40. : Definition text
41. continues here
42.
43. > Blockquote after definition
44.
45. ## Lazy Continuation
46.
47. Lazy term
48. : Definition line one
49. continues without indent (lazy continuation)
50. still part of the definition.
51.
52. ## Multiple Definitions for Same Term
53.
54. Shared term
55. : First definition
56. continues here
57.
58. : Second definition
59. also continues
60.
61. ## End with Definition
62.
63. Final term

### 💬 Copilot
I’m going to tweak the “keep Definition open across blank line” logic so nested lists remain stable across formatting, while still letting indented code after a blank line terminate the definition (fixing the golden idempotency regression).

<sub>⏱️ 166m 36s</sub>
### 💬 Copilot
Fixed the compile break and migrated **indented code blocks** into the dispatcher (with `has_blank_before_strict` plumbed through `BlockContext`).
While doing that, we hit a real semantic edge case: **definition-list blank-line continuation** was incorrectly swallowing indented code (and later caused a formatter idempotency failure); I fixed it by (1) not treating “indented code” as “nested structure” for the blank-line keep-open heuristic, and (2) ensuring definition “plain continuation” doesn’t eat an outdented blank line.
All tests are green again: `cargo test -q` passes.

### 👤 User
Pandoc has quite nice logic for continuation lines, but it feels like ours is scattered and somewhat ad-hoc. Is that your impression as well?

1. # Plan: Block dispatcher “prepared match” refactor
2.
3. ## Problem
4. Current `BlockParser::can_parse()` often does non-trivial work (e.g. fenced code parses fence + `InfoString::parse`, setext allocates, figure uses inline image parsing). This work is frequently repeated because:
5. - several parsers call `try_parse_*` again inside `parse()`
6. - `core.rs` calls `block_registry.detect(...)` multiple times per line in different branches
7. - `core.rs` separately re-implements “is this a block element marker?” checks (e.g. Definition continuation guard), further duplicating detection.
8.
9. ## Goal
10. Keep the good part of the refactor (Pandoc-like ordered registry + ability to “prepare/flush buffers before emitting”), while eliminating duplicate detection/parsing and reducing `core.rs` complexity.
11.
12. ## Approach (high level)
13. Introduce a **prepared match** concept: detection returns a match object that caches any expensive parsing results, and emission consumes that cached data (no re-parsing). Then rework `core.rs` so each line does **one** detection pass, decides whether the match is allowed (blank-line rules / interrupt rules), performs preparation, and emits.
14.
15. ## Key design decision (to confirm)
16. Two viable representations:
17. 1) **Trait objects + opaque payload** (recommended for minimal churn): registry remains `Vec<Box<dyn BlockParser>>`. Detection returns a `BlockMatch` containing a parser index + interrupt/blank requirements + `Box<dyn Any>` payload; emission downcasts payload.
18. 2) **Enum registry + typed payload** (slightly faster/cleaner types, but larger refactor): registry becomes `Vec<BlockParserKind>` and match payload becomes an enum.
19.
20. ## Workplan
21.
22. ### A. Baseline & safety
23. - [x] Run baseline tests/benchmarks to capture current behavior (`cargo test` at minimum).
24. - [ ] Identify a small set of “high-signal” golden cases to watch while refactoring (fenced code, setext, yaml/hrule ambiguity, refdefs).
25.
26. ### B. Introduce prepared-match API (non-invasive)
27. - [x] Add new types in `src/parser/block_dispatcher.rs`:
28. - `PreparedBlockMatch` (parser index + detection + cached payload)
29. - [x] Extend `BlockParserRegistry` with new entrypoints (keep old API temporarily):
30. - `detect_prepared(...) -> Option<PreparedBlockMatch>`
31. - `parse_prepared(match, ...) -> usize`
32.
33. ### C. Convert migrated parsers (start with biggest perf win)
34. - [x] Fenced code: detection parses fence + `InfoString` once; parse reuses cached `FenceInfo`.
35. - [x] ATX heading: detection returns cached level; parse uses it (no second `try_parse_atx_heading`).
36. - [ ] YAML: optionally cache “is yaml not hrule” disambiguation.
37. - [ ] Figure: cache validation span from inline image parse so it isn’t repeated.
38. - [x] Setext: remove allocation in detection (no `Vec`).
39. - [x] Reference definition: cache parse tuple from `try_parse_reference_definition` (payload currently unused by emitter).
40.
41. ### D. Refactor `core.rs` to “single detect per line”
42. - [x] Create one `BlockContext` per line and reuse it (avoid repeated rebuilds).
43. - [x] Replace the multiple dispatcher detections with one flow per line (detect once, then prepare/emit).
44. - [x] Rework the Definition continuation guard (`is_block_element` at ~1041) to delegate to the registry for migrated blocks (keeps special-cases for def/list/bq/html/tex).
45. - [x] Delegate nested-block marker probes (Definition continuation after blank line) to the registry instead of hardcoding fence/div/hrule checks.
46.
47. Notes:
48. - `BlockContext` no longer stores `&ContainerStack` to avoid long-lived borrows blocking mutation during preparation/emission.
49.
50. ### E. Consolidate ordering/precedence in the registry
51. - [x] Migrate HTML blocks into the registry (interrupting).
52. - [x] Migrate LaTeX environment blocks into the registry (interrupting).
53. - [x] Migrate line blocks into the registry (interrupting).
54. - [x] Decide fenced-div integration approach (needs container-stack interaction), then migrate (Option 1: dispatcher emits + core mutates containers).
55. - [ ] Move remaining “block start” checks from `core.rs` into the registry progressively (tables, indented code, lists, etc.), keeping Pandoc ordering notes.
56. - [ ] Ensure special-case precedence rules stay correct (e.g., YAML vs hrule, setext vs hrule, list vs header edge cases).
57.
58. ### F. Cleanup
59. - [ ] Remove old `can_parse/parse` API once all migrated blocks use prepared matches.
60. - [ ] Remove redundant detection logic left in `core.rs`.
61. - [ ] Run full test suite + clippy + fmt check.
62.
63. ## Notes / Constraints
64. - Maintain single-pass, lossless CST emission; prepared matches must not emit to the builder.
65. - Prepared payload should avoid borrowing `ctx.content` directly unless lifetimes are carefully managed; prefer storing indices / owned small strings only when needed.
66. - Performance expectation: dynamic dispatch/downcast overhead is negligible vs string scanning/allocs; eliminating repeated `InfoString::parse` etc. is the main win.
67.

### 💬 Copilot
Yes—Pandoc’s continuation handling is much more *centralized and state-driven*, while ours is currently split across at least three places (`parse_line` blank handling + `compute_levels_to_keep` + ad-hoc “definition continuation” in `parse_inner_content`). The indented-code migration made that pretty obvious: we had to touch multiple heuristics (definition plain continuation, blank-line keep-open, and “nested structure” probing) to restore correct behavior + idempotency.
I updated `plan.md` to mark **indented code migrated** and removed it from the remaining “block start” checklist.

### 💬 Copilot
Agreed—doing a **small, behavior-preserving refactor now** is worth it, because it prevents exactly the kind of cross-cutting regressions we just saw with indented code.
Next “obvious win” I’d do:
- Extract a single “continuation policy” helper (e.g. `src/parser/continuation.rs`) that owns:
- “is this blank line inside container?” decisions (`compute_levels_to_keep`)
- definition “plain continuation vs new block” decision
- the “nested structure probe” wrapper (with the right ctx flags)
- Then make `core.rs` call that in exactly one place, instead of duplicating ad-hoc checks.
If you want, I’ll start by introducing the helper with unit tests that pin current behavior (esp. the `plain_continuation_edge_cases` scenario) and then do a mechanical move of logic into it.

1. # Plan: Block dispatcher “prepared match” refactor
2.
3. ## Problem
4. Current `BlockParser::can_parse()` often does non-trivial work (e.g. fenced code parses fence + `InfoString::parse`, setext allocates, figure uses inline image parsing). This work is frequently repeated because:
5. - several parsers call `try_parse_*` again inside `parse()`
6. - `core.rs` calls `block_registry.detect(...)` multiple times per line in different branches
7. - `core.rs` separately re-implements “is this a block element marker?” checks (e.g. Definition continuation guard), further duplicating detection.
8.
9. ## Goal
10. Keep the good part of the refactor (Pandoc-like ordered registry + ability to “prepare/flush buffers before emitting”), while eliminating duplicate detection/parsing and reducing `core.rs` complexity.
11.
12. ## Approach (high level)
13. Introduce a **prepared match** concept: detection returns a match object that caches any expensive parsing results, and emission consumes that cached data (no re-parsing). Then rework `core.rs` so each line does **one** detection pass, decides whether the match is allowed (blank-line rules / interrupt rules), performs preparation, and emits.
14.
15. ## Key design decision (to confirm)
16. Two viable representations:
17. 1) **Trait objects + opaque payload** (recommended for minimal churn): registry remains `Vec<Box<dyn BlockParser>>`. Detection returns a `BlockMatch` containing a parser index + interrupt/blank requirements + `Box<dyn Any>` payload; emission downcasts payload.
18. 2) **Enum registry + typed payload** (slightly faster/cleaner types, but larger refactor): registry becomes `Vec<BlockParserKind>` and match payload becomes an enum.
19.
20. ## Workplan
21.
22. ### A. Baseline & safety
23. - [x] Run baseline tests/benchmarks to capture current behavior (`cargo test` at minimum).
24. - [ ] Identify a small set of “high-signal” golden cases to watch while refactoring (fenced code, setext, yaml/hrule ambiguity, refdefs).
25.
26. ### B. Introduce prepared-match API (non-invasive)
27. - [x] Add new types in `src/parser/block_dispatcher.rs`:
28. - `PreparedBlockMatch` (parser index + detection + cached payload)
29. - [x] Extend `BlockParserRegistry` with new entrypoints (keep old API temporarily):
30. - `detect_prepared(...) -> Option<PreparedBlockMatch>`
31. - `parse_prepared(match, ...) -> usize`
32.
33. ### C. Convert migrated parsers (start with biggest perf win)
34. - [x] Fenced code: detection parses fence + `InfoString` once; parse reuses cached `FenceInfo`.
35. - [x] ATX heading: detection returns cached level; parse uses it (no second `try_parse_atx_heading`).
36. - [ ] YAML: optionally cache “is yaml not hrule” disambiguation.
37. - [ ] Figure: cache validation span from inline image parse so it isn’t repeated.
38. - [x] Setext: remove allocation in detection (no `Vec`).
39. - [x] Reference definition: cache parse tuple from `try_parse_reference_definition` (payload currently unused by emitter).
40. - [x] Indented code: migrated into dispatcher (uses `has_blank_before_strict`).
41.
42. ### D. Refactor `core.rs` to “single detect per line”
43. - [x] Create one `BlockContext` per line and reuse it (avoid repeated rebuilds).
44. - [x] Replace the multiple dispatcher detections with one flow per line (detect once, then prepare/emit).
45. - [x] Rework the Definition continuation guard (`is_block_element` at ~1041) to delegate to the registry for migrated blocks (keeps special-cases for def/list/bq/html/tex).
46. - [x] Delegate nested-block marker probes (Definition continuation after blank line) to the registry instead of hardcoding fence/div/hrule checks.
47. - [x] Fix scattered continuation heuristics surfaced by indented-code migration (definition continuation + blank-line keep-open).
48.
49. Notes:
50. - `BlockContext` no longer stores `&ContainerStack` to avoid long-lived borrows blocking mutation during preparation/emission.
51.
52. ### E. Consolidate ordering/precedence in the registry
53. - [x] Migrate HTML blocks into the registry (interrupting).
54. - [x] Migrate LaTeX environment blocks into the registry (interrupting).
55. - [x] Migrate line blocks into the registry (interrupting).
56. - [x] Decide fenced-div integration approach (needs container-stack interaction), then migrate (Option 1: dispatcher emits + core mutates containers).
57. - [ ] Move remaining “block start” checks from `core.rs` into the registry progressively (tables, lists, etc.), keeping Pandoc ordering notes.
58. - [ ] Ensure special-case precedence rules stay correct (e.g., YAML vs hrule, setext vs hrule, list vs header edge cases).
59.
60. ### F. Cleanup
61. - [ ] Remove old `can_parse/parse` API once all migrated blocks use prepared matches.
62. - [ ] Remove redundant detection logic left in `core.rs`.
63. - [ ] Run full test suite + clippy + fmt check.
64.
65. ## Notes / Constraints
66. - Maintain single-pass, lossless CST emission; prepared matches must not emit to the builder.
67. - Prepared payload should avoid borrowing `ctx.content` directly unless lifetimes are carefully managed; prefer storing indices / owned small strings only when needed.
68. - Performance expectation: dynamic dispatch/downcast overhead is negligible vs string scanning/allocs; eliminating repeated `InfoString::parse` etc. is the main win.

### 💬 Copilot
I finished wiring the Definition “plain continuation vs new block” decision through the centralized `ContinuationPolicy` (and removed the duplicated ad-hoc detection logic from `core.rs` for that case).
Changes:
- `src/parser/core.rs`: Definition continuation now calls `ContinuationPolicy::definition_plain_can_continue(...)`.
- `src/parser/utils/continuation.rs`: `ContinuationPolicy` no longer pokes private `Parser` fields/methods; it takes the needed `BlockContext/lines/pos` explicitly.
- Also cleaned up now-unused imports in `core.rs`.
Validation:
- `cargo test -q` passes (all tests green).

Next up is fenced divs: I’ll inspect current fenced-div parsing and decide the minimal dispatcher integration that keeps container-stack behavior intact.

### 💬 Copilot
Next best win is migrating tables into the dispatcher (they’re still parsed in `core.rs` with multiple passes); I’ll inspect the current table/caption detection and then move it into a `TableParser` in `block_dispatcher.rs`.

### 💬 Copilot
Fixed the table migration regressions by teaching `TableParser` to properly handle **caption-before-table** detection without duplicating the caption as a paragraph.
Changes:
- `src/parser/block_dispatcher.rs`: `TableParser::detect_prepared()` now detects caption-before-table by probing the *real table start* (after caption + optional blank), but still parses from the caption line; `parse_prepared()` mirrors that by passing `table_pos` into `try_parse_*_table`.
- `src/parser/core.rs`: removed the old table parsing branches (including caption pre-scan) since the dispatcher now owns this.
- `src/parser/blocks/tables.rs`: restored `:` caption support (needed for existing tests + LSP symbol naming).
Validation: `cargo test -q` now passes (all tests).

### 💭 Reasoning
***Planning block migration**
I need to check what the user wants next since they said to keep going. I’ve got the plan.md in session-state, so I’ll read that and update the to-do list using the tools available. I’ll look at the block_dispatcher for remaining blocks to migrate. We’ve done the table, and I’ll inspect the registry to determine what hasn’t been migrated yet. It’s also important to decide on the next migration type like ordered lists or footnotes. I'll proceed with these tasks.**Inspecting remaining blocks**
I need to check the TODO comments to see what remains, particularly lists and divs like bulletLists, divHtml, ordered lists, definition lists, and footnote definitions. It seems that list parsing is still active in the core, while fenced divs might require a specific parser. I noticed the fenced_divs at the top; there could be a FencedDivParser in the dispatcher. I’ll inspect the BlockParserRegistry, especially the new and earlier entries, and start using the tools I have.*

1. # Plan: Block dispatcher “prepared match” refactor
2.
3. ## Problem
4. Current `BlockParser::can_parse()` often does non-trivial work (e.g. fenced code parses fence + `InfoString::parse`, setext allocates, figure uses inline image parsing). This work is frequently repeated because:
5. - several parsers call `try_parse_*` again inside `parse()`
6. - `core.rs` calls `block_registry.detect(...)` multiple times per line in different branches
7. - `core.rs` separately re-implements “is this a block element marker?” checks (e.g. Definition continuation guard), further duplicating detection.
8.
9. ## Goal
10. Keep the good part of the refactor (Pandoc-like ordered registry + ability to “prepare/flush buffers before emitting”), while eliminating duplicate detection/parsing and reducing `core.rs` complexity.
11.
12. ## Approach (high level)
13. Introduce a **prepared match** concept: detection returns a match object that caches any expensive parsing results, and emission consumes that cached data (no re-parsing). Then rework `core.rs` so each line does **one** detection pass, decides whether the match is allowed (blank-line rules / interrupt rules), performs preparation, and emits.
14.
15. ## Key design decision (to confirm)
16. Two viable representations:
17. 1) **Trait objects + opaque payload** (recommended for minimal churn): registry remains `Vec<Box<dyn BlockParser>>`. Detection returns a `BlockMatch` containing a parser index + interrupt/blank requirements + `Box<dyn Any>` payload; emission downcasts payload.
18. 2) **Enum registry + typed payload** (slightly faster/cleaner types, but larger refactor): registry becomes `Vec<BlockParserKind>` and match payload becomes an enum.
19.
20. ## Workplan
21.
22. ### A. Baseline & safety
23. - [x] Run baseline tests/benchmarks to capture current behavior (`cargo test` at minimum).
24. - [ ] Identify a small set of “high-signal” golden cases to watch while refactoring (fenced code, setext, yaml/hrule ambiguity, refdefs).
25.
26. ### B. Introduce prepared-match API (non-invasive)
27. - [x] Add new types in `src/parser/block_dispatcher.rs`:
28. - `PreparedBlockMatch` (parser index + detection + cached payload)
29. - [x] Extend `BlockParserRegistry` with new entrypoints (keep old API temporarily):
30. - `detect_prepared(...) -> Option<PreparedBlockMatch>`
31. - `parse_prepared(match, ...) -> usize`
32.
33. ### C. Convert migrated parsers (start with biggest perf win)
34. - [x] Fenced code: detection parses fence + `InfoString` once; parse reuses cached `FenceInfo`.
35. - [x] ATX heading: detection returns cached level; parse uses it (no second `try_parse_atx_heading`).
36. - [ ] YAML: optionally cache “is yaml not hrule” disambiguation.
37. - [ ] Figure: cache validation span from inline image parse so it isn’t repeated.
38. - [x] Setext: remove allocation in detection (no `Vec`).
39. - [x] Reference definition: cache parse tuple from `try_parse_reference_definition` (payload currently unused by emitter).
40. - [x] Indented code: migrated into dispatcher (uses `has_blank_before_strict`).
41.
42. ### D. Refactor `core.rs` to “single detect per line”
43. - [x] Create one `BlockContext` per line and reuse it (avoid repeated rebuilds).
44. - [x] Replace the multiple dispatcher detections with one flow per line (detect once, then prepare/emit).
45. - [x] Rework the Definition continuation guard (`is_block_element` at ~1041) to delegate to the registry for migrated blocks (keeps special-cases for def/list/bq/html/tex).
46. - [x] Delegate nested-block marker probes (Definition continuation after blank line) to the registry instead of hardcoding fence/div/hrule checks.
47. - [x] Fix scattered continuation heuristics surfaced by indented-code migration (definition continuation + blank-line keep-open).
48.
49. Notes:
50. - `BlockContext` no longer stores `&ContainerStack` to avoid long-lived borrows blocking mutation during preparation/emission.
51.
52. ### E. Consolidate ordering/precedence in the registry
53. - [x] Migrate HTML blocks into the registry (interrupting).
54. - [x] Migrate LaTeX environment blocks into the registry (interrupting).
55. - [x] Migrate line blocks into the registry (interrupting).
56. - [x] Decide fenced-div integration approach (needs container-stack interaction), then migrate (Option 1: dispatcher emits + core mutates containers).
57. - [ ] Move remaining “block start” checks from `core.rs` into the registry progressively (tables, lists, etc.), keeping Pandoc ordering notes.
58. - [ ] Ensure special-case precedence rules stay correct (e.g., YAML vs hrule, setext vs hrule, list vs header edge cases).
59.
60. ### F. Cleanup
61. - [ ] Remove old `can_parse/parse` API once all migrated blocks use prepared matches.
62. - [ ] Remove redundant detection logic left in `core.rs`.
63. - [x] Consolidate definition/blank-line continuation heuristics into `ContinuationPolicy`.
64. - [ ] Run full test suite + clippy + fmt check.
65.
66. ## Notes / Constraints
67. - Maintain single-pass, lossless CST emission; prepared matches must not emit to the builder.
68. - Prepared payload should avoid borrowing `ctx.content` directly unless lifetimes are carefully managed; prefer storing indices / owned small strings only when needed.
69. - Performance expectation: dynamic dispatch/downcast overhead is negligible vs string scanning/allocs; eliminating repeated `InfoString::parse` etc. is the main win.

### 💭 Reasoning
***Evaluating migration plan**
I’m considering whether to migrate the blockquote parser, but it seems like the list is larger than I initially thought. I want to look closely at how BlockEffect is being used. I’ll check out the FencedDiv parsers and see how the core handles block_effect after detection. It sounds like I’ll need to search for BlockEffect details and use my tools to do parallel grep and view functions. Let's ensure I have all the information!*

<sub>⏱️ 751m 15s</sub>
### 💬 Copilot
I’ll quickly assess what blocks are still handled in `core.rs` (esp. lists/blockquote/footnotes) and propose the next migration that minimizes container-stack churn.

### 💭 Reasoning
***Exploring blockquote migration**
I’m thinking about the blockquote parsing and how it currently uses a container stack. It's tricky, but maybe we can treat it as an effect with OpenBlockQuote/Close. The user wants to migrate the remaining blocks, specifically block_quotes to the dispatcher, so I’ll search for blockquote parsing in the core and existing blocks module. I need to keep my response short, so I’ll explore the current module and see how to implement a BlockQuoteParser in the dispatcher.**Assessing blockquote handling**
I'm evaluating if blockquotes can work with containers. It seems easier to maintain the core's container logic but detect if a line starts with `\>` for blockquote identification. The dispatcher contract expects parse() to return consumed lines and emit nodes directly. Since blockquotes require nested parsing, I could keep blockquote handling in the core for now and prioritize migrating lists instead. However, I could consider modularizing blockquote handling, similar to fenced divs, while focusing on per-line markers.**Considering footnote migration**
I’m thinking that migrating the core parse loop might be tough, so I should consider moving OrderedList, DefinitionList, and Footnote definitions instead. Footnote definitions could utilize `try_parse_footnote_marker` for handling in the core, or perhaps I can move them to the dispatcher. I need to check the module `src/parser/blocks/footnotes.rs` and look for the structure around footnote handling to see if it can manage interruptions and blank lines. Next, I’ll decide whether to migrate `FootnoteDefinitionParser` and how to parse those into `FOOTNOTE_DEFINITION` nodes.**Proceeding with tool calls**
I’m thinking about the next steps, so I’ll start with the tool calls: using glob to identify block files and grep to locate the footnote definitions. I also plan to examine the relevant sections in the core to gather more context. After gathering this information, I’ll be in a better position to decide how to proceed with the migration. I’ll do these tasks in parallel to save time!*

### 💬 Copilot
I’ll pick the next Pandoc-ordered block to migrate (likely footnote definitions or lists) by inspecting what’s still in `core.rs` and what block helpers already exist.

### 💭 Reasoning
***Evaluating migration tasks**
I need to continue with the migration work items. "Let's keep going" implies that I'll be moving blocks into the dispatcher, focusing on the remaining ones: lists, blockquotes, definition lists, and footnote definitions. Footnotes are already excluded, but we can include footnote definitions now while simplifying the core. The interactions with containers make this more complicated, especially for blockquotes and lists, which have their own parsing challenges. It might be best to tackle blockquotes first before diving into the other types.**Considering fenced div integration**
The user asked to discuss fenced divs after the HTML and LaTeX blocks. Fenced divs are already integrated with effects, but I need to decide on the integration approach for the div containers. It appears the current implementation may be incomplete, needing better handling of the container stack and node closures. The FencedDivOpenParser emits the necessary nodes, but I need to ensure that nested blocks are allowed inside. I'll take a closer look at the close parser to see how it handles this and finalize the implementation.*

### 💭 Reasoning
***Planning migration steps**
I need to outline the next steps for the migration process. The user mentioned to keep pushing forward. I’m thinking we'll focus on migrating footnote definitions next since they have a specific handling case. From the Pandoc order, footnote definitions come after some other blocks. There are also fenced divs pending to discuss, but we’ve already integrated those. My main task now is to work on implementing BlockParser for the FootnoteDefinition in the dispatcher.**Considering footnote parsing logic**
Footnote parsing is pretty tricky since it's closely tied to container management and indentation. Right now, the core has custom logic to handle footnote definitions by opening a FOOTNOTE_DEFINITION node and managing content with specific rules. It seems best to keep this container approach in the core while letting the dispatcher manage the initial detection and emission of the opening marker and first line. There’s a potential idea to extend BlockEffect for footnote handling, which could work. I need to ensure I close the previous footnote container too when making these changes.**Structuring footnote handling**
I need to manage core behavior for handling footnote definitions, especially ensuring that any open footnotes are closed before starting a new one. It’s a bit different from how fenced divs work, as I can't rely on a specific close marker. The effect should guide the core to close previous footnotes if they’re open. I might implement an OpenFootnoteDefinition effect in the core, ensuring we close previous footnotes before parsing to prevent nesting. I’ll need to figure out the best way to incorporate this into the preparation and effect handling processes.**Exploring footnote migration**
The user has indicated they want to keep moving forward with more blocks migrated, even though I was thinking about making the smallest changes. I plan to implement footnote definitions using a dispatcher parser while keeping the core logic to a minimum. When there's a match, the core will prepare and call parse_prepared to emit the footnote definition node along with the first line. I'll need to check how the continuation for footnote containers works, so I'll search the core for Container::FootnoteDefinition handling and reuse existing code where I can.*

I’ll migrate footnote definitions (`[^id]:`) into the block dispatcher next, preserving the existing container-based continuation behavior and then remove the special-case from `core.rs`.

### 💭 Reasoning
***Evaluating footnote logic**
I’m really diving into the footnote logic here. The container stack doesn’t seem to include a Paragraph container, which could lead to issues with subsequent indented lines starting new paragraphs. I see that within the footnote definition, the first line content stays open for continuation lines. Since footnote continuation lines are indented, they could be treated as part of the same paragraph, which relies on proper indentation handling. I’m considering whether to treat the first line as standalone or part of the same paragraph.**Analyzing footnote continuation**
I'm considering how footnote continuation lines work, particularly their indentation and how they interact with paragraph formatting. The core's total indentation stripping treats indented lines as normal lines, but paragraph continuation can create a new paragraph if needed. I’m wondering if subsequent indented lines should append to the original. In Pandoc, continuation lines with the same indentation indeed become part of the footnote. We need to keep the paragraph open, so the container stack must track its state after the first line. It seems like the BlockParser might need adjustments.**Exploring footnote container manipulation**
I'm thinking about how to use effects for container manipulation after parsing, especially with footnotes. After opening a footnote container, we could check if the first line has content and then start a paragraph container to append that content. The block parser might emit a FOOTNOTE_DEFINITION start with the marker token and necessary payload data. The core could then push the Container::FootnoteDefinition and begin a paragraph if there’s inline content. This approach aligns with earlier core logic, allowing for effective paragraph handling while migrating to a dispatcher. We’ll need a new effect variant for this.**Examining footnote definition handling**
I’m considering how to update the handling of footnote definitions. We need to add a match for OpenFootnoteDefinition to close existing definitions, push a new container, and possibly append content. But handling effects is tricky since it currently occurs after parsing. The old core closed the paragraph before starting the footnote, so we must determine if footnote definitions can interrupt paragraphs. The old code allowed footnotes to interrupt without requiring a blank line, but I'm not sure about that. I think detection should indicate if footnotes can interrupt, perhaps as YesCanInterrupt.**Constructing footnote detection logic**
I’m thinking it’s best to preserve old behavior by treating footnotes as YesCanInterrupt, allowing parsing without requiring a blank line. In the current dispatching logic, blocks marked as YesCanInterrupt will close the paragraph if there's no blank line. We can implement detection to always return YesCanInterrupt but ensure that footnotes take precedence over reference definitions. I’ll need to check how content is passed to the context after stripping indentations. The parse preparation should start FOOTNOTE_DEFINITION nodes while also managing marker text and indentation properly. I'll examine the old core code for insights on handling these cases.*

### 💭 Reasoning
***Considering migration strategy**
I'm thinking about minimizing changes for now, maybe we should keep footnote definitions managed in the core while we migrate lists. The user said to keep going. Should I work on ordered lists or bullet lists next? Both seem to require a heavy container stack. Maybe blockquotes are the next step since they also involve that stack. It looks like I need to decide on keeping container-manipulating blocks outside the dispatcher while migrating “leaf” blocks. The user wants everything migrated eventually, so I can consider a hybrid approach where the dispatcher can detect these blocks and manage them with existing logic.**Planning footnote migration**
I'm considering the user's "keep going" request and the previous notes on fenced divs, which we already have integrated. The next items on my to-do list are bullet and ordered lists, definition lists, and footnote definitions. I wonder if I could migrate footnote definition detection into the dispatcher while keeping the parsing in core. I might add a parser to return an effect like OpenFootnoteDefinition, with a payload to avoid re-parsing. But, hmm, I should ensure BlockParserRegistry doesn't directly parse but returns something useful. I'll need to find a way to handle this effectively.**Structuring footnote definitions**
I'm exploring how to handle both footnote definitions and container pushes in parsing. For footnote definitions, I realize the parsing needs to happen before the container push. The process would involve starting a node with builder.start_node(FOOTNOTE_DEFINITION) and having the core push the container. As the builder stays inside the node, any inner content will become children of that node. This means parse_prepared should start the node but not finish it, letting the core finalize when closing the container, which aligns with how other container types work.**Outlining footnote definition handling**
I’m realizing that the footnote definition block can follow a specific pattern: the parser will start the FOOTNOTE_DEFINITION node and emit the marker tokens, but it won’t finish that node. The core will push the Container::FootnoteDefinition, keeping the node open until the container is popped. I still need to parse the first line's inline content after the marker, which may require a container stack. I’m considering deferring the inline parsing, treating the remainder of the marker line as a plain TEXT token inside FOOTNOTE_DEFINITION. However, tests might expect inline parsing, so I'll quickly check the cst for the reference_footnotes case.*

### 💭 Reasoning
***Migrating content blocks**
I'm working on migrating blocks and weighing whether to handle footnote definitions or lists next. I see that according to the plan, there should be a discussion about fenced divs after dealing with HTML, LaTeX, or line items, but it looks like fenced divs are already integrated into the workflow. The next step for Pandoc is to manage bullet lists and HTML blocks. I’ve realized that footnote definitions could be pushed to the dispatcher to reduce special cases and improve registry ordering. This might need a new BlockEffect variant for OpenFootnoteDefinition.**Managing footnote definitions**
I need to ensure that I close previous footnotes and open new nodes during the migration process. One option is to implement a FootnoteDefinitionParser that outputs a FOOTNOTE_DEFINITION node, but it seems like parse doesn’t have container access. Maybe I should tell the core to push the container based on some payload. Introducing a BlockEffect::OpenFootnoteDefinition could work, using PreparedBlockMatch to manage content starts. In the core, I could close any previous footnote containers before opening new ones to keep things minimal. After migrating, I'll streamline footnote handling through the registry.**Implementing FootnoteDefinitionParser**
I see that according to Pandoc's order, the noteBlock should come before the referenceKey, so I need to position the FootnoteDefinitionParser before the ReferenceDefinitionParser in the new() function. That sounds good! Now, to create the FootnoteDefinitionParser, I need to check if footnotes are enabled in the config. If the context doesn't have the footnotes extension, I should search for it in the config extensions using grep. Let's get that structured out clearly!*

### 💭 Reasoning
***Considering migration adjustments**
The user wants me to keep going with the migrations, but we broke tests before, so we need a minimal fix to restore behavior. One option is to revert the footnote definition migration by removing the FootnoteDefinitionParser and reintroducing the core logic for footnote ignoring. That could be a small tweak to get back on track. However, to properly implement footnotes in the dispatcher, we might need a new BlockEffect variant and modifications in core handling. It’s a bigger task, but doable!**Revising node handling for footnotes**
The old core started a node and kept it open until the container was later closed in close_containers. This means that ContainerStack::close_containers_to knows how to handle FOOTNOTE_DEFINITION nodes. I need to ensure that in parse_prepared, I start the node and emit a marker and perhaps the first line of content, but keep it open by pushing the container in core later. This approach mirrors how we handle fenced divs, where the node stays open until closed. For footnotes, the same logic applies.**Improving node management in the parser**
In the current parser, parse_prepared returns a usize, which doesn't allow me to indicate that a node is left open. However, it doesn't need to call finish_node(). For fenced divs, the parser starts FENCED_DIV and DIV_FENCE_OPEN without finishing the FENCED_DIV, which is fine. I can apply the same principle to footnotes by starting FOOTNOTE_DEFINITION in parse_prepared and not finishing it. The core will then push Container::FootnoteDefinition when the footnote ends. To handle this, new BlockEffect variants like OpenFootnoteDefinition could be useful, incorporating content_col in the payload for core pushing.**Enhancing footnote handling in parsing**
I see that we can downcast in effect handling, which is a bit messy but could work as a minimal solution. Alternatively, I might keep BlockEffect::None and detect footnotes in the core using block_match.name, but that isn't ideal since the core doesn't know that yet. Adding new BlockEffect variants like OpenFootnoteDefinition and CloseFootnoteDefinition could be a better path. We also need to ensure footnote definitions take precedence over reference definitions and allow them to interrupt paragraphs without requiring a blank line. We'll remove any outdated core logic regarding footnote definitions once the new parser is functioning properly.**Implementing footnote parsing**
I need to work on the footnote parser's parse_prepared to replicate the old functionality. The container stack expects a FootnoteDefinition variant. When closing, it finishes the FOOTNOTE_DEFINITION node, which was previously constructed in the core. I plan to implement FootnoteDefinitionParser in block_dispatcher.rs, storing a payload with necessary content. It's crucial to ensure first line content is treated like paragraph content and to manage indentation correctly.
I might have to leave the first line content to the core for processing, in a way that traditionally handled paragraphs, without complicating the emission logic. This could help us maintain expected output and behavior in line with prior implementations.**Clarifying footnote content handling**
Footnote definitions should consume one line, including the marker line. The core effect handling will then append the first line content, but I've realized we advance the position after returning true from the main loop. Since the position is incremented after effect handling, we can append to the builder using the content substring from the original content. I need to consider how indentation and markers are handled, especially in list contexts.
For footnotes, it seems I'll need to ensure proper handling of marker text and newline preservation, adjusting as needed based on the core's processing rules. To be precise, I'll inspect how the content is defined earlier in the core.*

### 💭 Reasoning
***Evaluating footnote parser issues**
I’ve added a footnote parser, but it only handles the first line and doesn’t manage continuation indentation or stack properly. This is causing LSP tests to fail since footnote definitions aren’t parsed as multiple blocks correctly. It seems the dispatcher is outputting only the current line, which confuses subsequent indented lines, treating them like regular paragraphs. I need to integrate the footnote parser properly into the ContainerStack to maintain its context. There’s a lot to adjust for a clean solution!**Refining footnote handling**
I’m considering extending BlockEffect to include StartFootnoteDefinition with the content column. This would involve the core pushing a FootnoteDefinition container and the builder node starting as before. I realize the footnote definition wraps its content and closes automatically, with the closing logic likely handled by the container stack.
The dispatcher should ease the creation of this node and push the container via the effect, similar to how a fenced div works. I need to figure out storing the effect since Copy is currently an issue; it might require some restructuring, which I find a bit messy!**Updating BlockEffect for footnotes**
I'm thinking it’s better to extend BlockEffect to include OpenFootnoteDefinition and store content_col directly in the payload. Perhaps I can set content_col as a constant value of 4 since it's always that way. This would allow the core to push Container::FootnoteDefinition with content_col fixed at 4 and maintain the continuation behavior.
I need to ensure that the builder node starts correctly and that the first line content is processed via the paragraphs module. The overall behavior should mimic how the core operates, especially how it handles content inside the footnote definition container.**Addressing dispatcher limitations**
I need the dispatcher parse to function like the old core: starting a node, emitting a marker token, and pushing the container. If the first line isn't empty, it should call paragraphs::start_paragraph_if_needed. However, this requires access to the ContainerStack, which block parsers currently lack. This poses a significant issue because the dispatcher can only manage builder and context, not containers beyond the effect.
To keep things minimal, I could leave footnote handling in the core, but the user prefers to continue migrating the rest. Maybe footnotes need a deeper integration where the dispatcher can handle detection while the core manages container pushes and paragraph creation.**Revising the footnote parser approach**
I'm considering a different method for the footnote parser. It might emit the FOOTNOTE_REFERENCE marker token first, and then the core could handle the remainder. One option is splitting the parsing into two stages: first, emitting the start node and marker, and then allowing the core to manage the container and first line content by appending it to a paragraph buffer.
I need to ensure the tokens stay in the correct order, possibly keeping it simple by emitting only the FOOTNOTE_DEFINITION start node initially. Also, I should check how the paragraphs module handles inline parsing, especially for single-line paragraphs versus more complex structures.*

### 💭 Reasoning
***Evaluating footnote migration**
I tried migrating footnote definitions to the dispatcher, but I implemented a too simplistic parse that doesn't push the Container::FootnoteDefinition. This caused failures in subsequent tests because indented lines weren't stripped. So, I need to make footnote a container effect, not just emit nodes. The dispatcher architecture currently supports effects only for fenced div features, and I’m thinking of extending BlockEffect to include OpenFootnoteDefinition, but I should be careful with how we handle closing previous footnote containers.**Refining footnote emission**
I need to handle the emission of footnote markers and the first line similarly to the old logic, using paragraph buffering and the container stack for multi-line content and nested blocks. It feels more efficient to reuse old logic instead of creating something new in the dispatcher. In parse_prepared, we should emit the FOOTNOTE_DEFINITION and FOOTNOTE_REFERENCE tokens, then push the container with content_col. However, the dispatcher doesn’t have access to the ContainerStack, so I've got to manage that in the core based on the effect.**Deciding on footnote parsing**
I have a few options for handling footnote parsing. First, I could keep it in the core instead of moving it to the dispatcher. Alternatively, I might expand the BlockParser trait to access the container stack, but that seems too complicated. Another idea is to have the footnote parser effect trigger a specialized hook in core to build the footnote container and first line content. Given the constraints and recent test failures, the simplest approach could be to revert the footnote migration and keep processing in core. However, it's worth exploring other blocks for migration too.**Moving forward with footnote migration**
I don't want to lose progress, so I think we can still implement footnote migration correctly with minimal changes by extending effects and core. I noticed that the container stack has a FootnoteDefinition variant, but currently, we're getting warnings about it never being constructed since we removed the core logic.
My approach is to move footnote detection to the dispatcher while keeping the paragraph buffering in core. The FootnoteDefinitionParser should handle detection and return a payload that includes marker_end and possibly marker_text. We need to ensure that the original line text is preserved for losslessness, just like it was done before.**Refining footnote implementation**
I realize that the content parameter is stripped_content after removing container indent. For footnotes at the top level, this is fine, but it may differ inside a blockquote or list. Footnote definitions likely work within those as well, which means we should maintain indentation to properly emit marker_text.
When dealing with the CST, I noticed it expects FOOTNOTE_REFERENCE tokens to maintain specific formatting, including indentation. It’s crucial to preserve original line text for losslessness, which means carefully managing leading whitespace. To simplify this process, I think it might be best to revert changes and keep parsing within core for now while integrating some of the new logic.**Implementing footnote definitions**
I need to ensure that marker_text captures both the marker and any spaces following it, but not the newline. The first_line_content must include the newline from the original content. The parse_prepared function should use ctx.content to generate the marker and first line values, while the previous logic focused on handling stripped_content carefully.
I'll begin the FootnoteDefinitionParser implementation by creating the payload that includes marker_end and potentially content_start for the first line. The function should initiate the FOOTNOTE_DEFINITION node, emit the FOOTNOTE_REFERENCE token from ctx.content, and manage any associated paragraph states on the core side. We must ensure existing footnote containers are closed before starting a new one to prevent nesting issues. I might need to adjust the sequence so that we close the old containers prior to the parse_prepared call for footnotes.**Refining footnote logic**
I’m thinking about adjusting the effect handling to ensure we close old footnote containers before calling parse_prepared. This approach reflects the past logic where previous containers were closed prior to starting a new footnote node. I’ll implement a "pre_effect" stage, specifically for OpenFootnoteDefinition.
I'll also create a BlockEffect enum to manage this. Before calling parse_prepared, if the effect matches OpenFootnoteDefinition, I need to ensure any currently open footnote containers are closed. After that, parse_prepared will start the FOOTNOTE_DEFINITION node and handle first line content for paragraphs appropriately, ensuring that indentation rules are respected to close containers at the right time. I might need to dive deeper into the parse_line function to clarify when footnote containers will close under indentation conditions.*

### 💭 Reasoning
***Inspecting footnote handling**
In Pandoc, a footnote starts with the line `[^id]:`, and its content continues if indented with four spaces or if subsequent lines carry that indentation. This structure resembles a Definition container. It seems that the ContainerStack in our parser likely manages closing based on indentation and blank lines. To confirm this, I should take a look at container_stack.rs and see how it's utilized, especially focusing on FootnoteDefinition.*
---
<sub>⏱️ 760m 9s</sub>
### 💬 Copilot
I’m going to restore correct multi-line footnote semantics by reintroducing the footnote container behavior (via a dispatcher effect like fenced divs) and then rerun tests.

### 💭 Reasoning
***Inspecting footnote logic**
I'm planning to check the current core.rs file to understand the container closing logic related to indentation. I need to focus on what decides to keep the FootnoteDefinition open. I think the ContinuationPolicy compute_levels_to_keep function likely handles the footnote logic. So, it looks like I'll need to inspect the ContinuationPolicy module specifically for footnote decisions, which means I'll be searching for it directly to get a clearer understanding.*

I’m going to inspect how the core keeps/ends `FootnoteDefinition` containers so we can mirror that with a dispatcher “open container” effect and restore multi-line footnote parsing.

### 💭 Reasoning
***Addressing footnote migration**
I need to tackle the issue of footnote migration. Right now, the FootnoteDefinitionParser in the dispatcher emits a footnote marker token and maybe a paragraph with text, but it doesn't push the container. Previously, the core managed footnote definitions by starting a node and pushing a Container::FootnoteDefinition. Since that logic was removed, tests are failing. I need to reintroduce container semantics, possibly using BlockEffect::OpenFootnoteDefinition, although the effect enum currently only includes None, OpenFencedDiv, and CloseFencedDiv. I should check the block_dispatcher.rs effect enum next.*

1. //! Block parser dispatcher for organizing block-level parsing.
2. //!
3. //! This module provides a trait-based abstraction for block parsers,
4. //! making it easier to add new block types and reducing duplication in parse_inner_content.
5. //!
6. //! Design principles:
7. //! - Single-pass parsing preserved (no backtracking)
8. //! - Each block parser operates independently
9. //! - Inline parsing still integrated (called from within block parsing)
10. //! - Maintains exact CST structure and losslessness

### 💭 Reasoning
***Evaluating footnote parsing**
I think it's acceptable to have minimal tests passing. However, the user's goal is to migrate blocks, and footnotes act as container-openers like fenced divs. We've used BlockEffect for fenced divs with separate open/close lines, but footnotes require opener plus body starting on the same line, making it more complex. It seems like I should implement this similarly to how definition list parsing works, perhaps by checking for footnote markers at the beginning of parse_inner_content.**Analyzing footnote parser integration**
The user wanted to use a registry, so I'm considering creating a FootnoteDefinitionParser that detects prepared footnotes. The parse_prepared function might need to return an effect that opens the footnote with the marker_end without emitting a paragraph. Since parse_prepared is called earlier, I could avoid the standard call for footnotes and create a custom path. This change might need some modifications in the core dispatcher, which seems a bit ad hoc. Maybe the simplest approach is to remove FootnoteDefinitionParser from the registry and restore core footnote parsing. I'll check the old core logic in the git history to see if it's still accessible.**Searching git history**
I think it's time to search the git history to find the core code I'm looking for. I'll run a command in bash like `git log -n 20 -- src/parser/core.rs` to locate the relevant commits. Using tools like this can help me quickly pinpoint changes made to the file. This might reveal the footnote logic or any alterations that would inform my next steps in parsing footnotes properly. Let's see what I can find!*

### 💬 Copilot
I’m going to restore correct multi-line footnote container behavior by reintroducing core-side footnote parsing (using the dispatcher only for detection later), then rerun the test suite.

### 💭 Reasoning
***Revising footnote logic**
I’m figuring out a simple fix for the footnote change: either remove the FootnoteDefinitionParser or keep it without using it, while bringing back the core's explicit definition logic. I need to reconstruct it using the current container semantics. So, we have Container::FootnoteDefinition, but we never implemented it. I’m also thinking about how footnote markers should work and whether they can interrupt paragraphs based on current logic; seems I need to clarify detection conditions.**Clarifying block handling**
I’m thinking through how to handle blocks that require a blank line. For these, returning Yes seems correct. In the footnote parser, they treat having a blank line as Yes, while something without one gives a YesCanInterrupt response. This feels flipped, but maybe not crucial. I need to check how other parsers handle this. Reference definitions might interrupt paragraphs, and it seems that yes triggers actions related to paragraph handling, but without closing the paragraph. It’s still confusing!**Examining block parsing**
I’m considering how the parse_prepared function handles block emissions. If it returns true and advances the position, would that leave the paragraph open? It seems like without a blank line, there could still be an open paragraph. In cases where detection is Yes, it doesn't close the paragraph—it just parses the block. This could lead to block nodes being inside the paragraph container. I’m also thinking about how reference definitions interact with this and whether they should interrupt paragraphs by default.**Analyzing reference definitions**
I’m looking at how reference definitions are treated regarding blank lines and paragraph interruption. They don't require a blank line before but can interrupt paragraphs, which feels like they should behave as YesCanInterrupt by closing the paragraph if it's open. However, the core's logic doesn’t close paragraphs for Yes, only for YesCanInterrupt. The reference definition parser should ideally return YesCanInterrupt, not just Yes. It’s interesting that the comment says no preparation is needed, implying they should not close a paragraph. This might complicate things!**Examining reference definition handling**
I'm inspecting how the reference definition parser processes indentation and whether it uses builder tokens within a paragraph. This doesn’t seem quite right, so I want to check how paragraphs are buffered. The Paragraph container holds segments in a buffer until it’s closed. If we hit a reference definition while the paragraph is still open and don’t close it, parse_prepared might emit directly to the builder. I need to clarify when the paragraph node is open in this design, particularly with respect to starting paragraphs in the buffer.*

### 💭 Reasoning
***Troubleshooting footnote migration**
I need to address the footnote migration failure. We’ve introduced a new FootnoteDefinitionParser in the dispatcher, but it currently doesn’t handle the container properly. To parse subsequent lines, I need to open the footnote container. The architecture utilizes a ContainerStack and requires proper indent stripping, but right now, FootnoteDefinition is not pushing, so the content_indent won’t include the base. I need to pinpoint where block_ctx.content_indent is computed and see how footnote definitions should align regarding indentation.**Revisiting footnote parser logic**
I'm working on the ContinuationPolicy in compute_levels_to_keep regarding footnotes. It adds content_col to content_indent_so_far and keeps the level if raw_indent_cols meets the min_indent, which equals the max of content_col or 4. This suggests that content_col serves as additional indent from the footnote prefix. In the current footnote parser, marker_end is measured in bytes instead of columns, and it's not integrated correctly. I think we should return to the container-based parsing method, similar to how we handled other blocks, while also considering how to modify BlockEffect to include the necessary payload.**Analyzing footnote structure**
I’m considering a simpler approach to managing effects, specifically avoiding new effect variants with data. I think deriving content_col from the payload and using just the OpenFootnoteDefinition effect could work. However, core has to consider that parse_prepared already consumes the payload. Once parse_prepared returns lines_consumed, I realize I access block_match.payload, which is passed to parse_prepared with the PreparedBlockMatch reference. I need to check the block_registry's parse_prepared signature and take a closer look at its view in block_dispatcher.rs for clarity.*

### 💭 Reasoning
***Fixing footnote migration**
I need to address the issue with footnote migration. Currently, the FootnoteDefinitionParser creates a FOOTNOTE_DEFINITION node but doesn't include container semantics, which is making multi-line footnotes fail. One option is to revert recent changes and disable the dispatcher parser, but since the user wants to continue migration, this is tricky. Restoring previous behavior would be a quick solution, but it’s unclear how to implement minimal core-side footnote parsing. Alternatively, I could look into implementing a new BlockEffect for footnote definitions, although that adds complexity with node management across lines.**Revising footnote handling**
To handle footnotes, I want to start the FOOTNOTE_DEFINITION node and push the Container::FootnoteDefinition, parsing the remainder of the line as a paragraph. It makes sense to bring back footnote parsing in the core where the old code was removed and adjust the dispatcher to avoid parsing footnotes. As we’re mid-refactor, keeping the FootnoteDefinitionParser but tweaking it to manage the open container could work. This would allow the core to push the container while maintaining a consistent structure. For the footnote, parse_prepared should handle starting the node and emitting the necessary tokens.**Clarifying footnote parsing structure**
I need to ensure that the rest of the line after the footnote marker is treated as paragraph content, relying on the core's regular parsing for any following lines. The core should know to keep the footnote definition node open after the parse_prepared function returns the consumed lines, which is likely just one for the marker line. After starting the node and emitting the marker tokens, it shouldn’t finish the node until the footnote ends, utilizing the core’s close_containers_to function. I’ll need a container to represent the open FOOTNOTE_DEFINITION and adjust the builder to start the node when the effect opens the footnote.**Restructuring footnote handling**
I’m considering a restructuring in the dispatcher to detect footnote definition lines and return an effect called OpenFootnoteDefinition, which would include the marker_end and content_col. Currently, BlockEffect only supports FencedDiv, but I could extend it to include OpenFootnoteDefinition. However, effects cannot store data directly; maybe I can create variants without data and use payloads. The core's effect handling also needs to be updated to manage opening and closing footnotes. The footnote container should stay open for subsequent blocks until it encounters a line that isn't properly indented.**Searching for footnote logic**
I want to look through older commits to find footnote logic, but my initial grep search shows no matches. I should check the git show command for the commit just before footnote removal, possibly in c0672ae, since it appears that core.rs no longer includes footnote handling. It seems the removal happened around that commit. I'll also consider earlier commits, like dc2a110, to find any remnants. Using `git show` should help me track down the removed footnote logic in core.rs, especially looking for the "FOOTNOTE_DEFINITION" string in the history.*

### 💭 Reasoning
***Addressing footnote issues**
I need to address the current breakage with footnote definitions in the dispatcher not opening a container. I have two paths: I can either add a new BlockEffect for OpenFootnoteDefinition, similar to the fenced div, or adjust the FootnoteDefinitionParser to only start the node and emit the marker before pushing the container. It’s crucial to ensure the closing node occurs properly when the container closes, as previously done in the old core for footnotes.**Clarifying paragraph line handling**
I need to note that the `append_paragraph_line` function expects a raw line string with a newline to preserve line endings. In the old code, it seems like `first_line_content` didn't include the newline because it was derived from stripped content. However, content should include the newline as it's from the `split_lines_inclusive`, meaning each line retains its newline unless it’s the last line. In the dispatcher, the context content passed to the parser looks promising, but my current approach in the FootnoteDefinitionParser might be inadvertently using the wrong newline token.**Mimicking old behavior for footnotes**
I need to ensure we replicate the old behavior by creating a FOOTNOTE_DEFINITION node and emitting the marker token while pushing the container via an effect. However, the block dispatcher in `parse_prepared` doesn't have access to the containers to push them at the right time. I realize that we need both effect and core adjustments to accomplish this. I'll keep the `content_col` constant at 4 for now, ensuring indentation and continuation rules are consistent with tests. Closing logic will also check the minimum indentation correctly.**Understanding footnote and paragraph behavior**
Footnote definitions can indeed interrupt paragraphs without needing a blank line, which matches the old logic. In that code, footnotes would be recognized regardless of whether there was a blank line. The detection mechanism in our dispatcher seems inverted; it should set detection to `YesCanInterrupt` always, rather than only when a blank line is present. In our current setup, if we're in the middle of a paragraph, we correctly set it to `YesCanInterrupt`, so that part is on track!**Clarifying footnote detection and semantics**
For the document start or when there's a blank line before, we set detection to `Yes`, allowing the system to call `prepare_for_block_element`, which closes paragraphs. However, this might affect footnotes' ability to interrupt paragraphs when necessary. It appears that the core uses `Yes` to indicate that interruptions are not allowed without a blank line, meaning that for footnotes, I should set detection to `YesCanInterrupt` to match the old behavior. I also need to ensure that the marker token includes the correct format, including spaces after it.*

### 💭 Reasoning
***Addressing footnote migration**
I need to focus on fixing the broken footnote migration. The simplest option would be to either revert the footnote changes or create proper container semantics. For minimal disruption, I could remove the FootnoteDefinitionParser in the dispatcher and bring back the old core footnote parsing block. This should restore functionality and allow for ongoing migration of other blocks later. The user has shown interest in continuing migration despite the current issues. Now, I need to determine the next steps based on the current state of the repo.**Planning footnote migration fix**
Given the complexity, I propose reverting the footnote migration attempt. This means deleting the FootnoteDefinitionParser registration in the dispatcher and restoring the core footnote parsing code from e55bcc3, updating it for the current environment. I’ll also fix any unused import comments. It’s important to ensure this adjustment doesn’t conflict with dispatcher detection of footnotes, especially since some comments might now be outdated. We need to clarify how footnotes are currently parsed, ensuring they’re handled properly.**Analyzing core module dependencies**
I’m considering whether the core really needs the reference_links module since there’s an unused import warning for `use super::blocks::reference_links;`. Since we’re reintroducing footnote parsing, this import might actually be useful again. In the old code, it used `try_parse_footnote_marker` and `try_parse_reference_definition`, but now reference definitions are managed by the dispatcher. We’ll only need `try_parse_footnote_marker`, so I’ll update core.rs accordingly. Also, we need to manage container closing rules, including for footnotes. I'll re-add the footnote parsing block just before the reference definitions.**Determining footnote parsing placement**
Since reference definitions are now in the dispatcher, I’m considering where to insert the footnote parsing. In the old code, footnotes were placed after fenced code and before reference definitions, as well as indented code blocks. In the current core.rs, dispatcher detection starts earlier, so I need to position the footnote parsing carefully. It should happen before parsing lists, definition lists, or line blocks to ensure the dispatcher doesn’t incorrectly match footnotes after removing the FootnoteDefinitionParser. I think placing footnote definitions before lists is likely the way to go.**Revising footnote handling in parsing**
In Pandoc, footnote definitions can interrupt paragraphs, starting with `[^`, so I should check for footnotes before parsing list markers. This means inserting my footnote check right before line 1067 where lists begin. I need to consider the handling of content indentation after stripping. The old code managed footnote markers and included whitespace for lossless emission, so I'll need to ensure that any indentation from parent containers is emitted correctly. Ultimately, I’ll ensure footnote definitions are properly closed and that we maintain necessary whitespace for lossless parsing. It’s quite the puzzle to make everything fit!**Adjusting footnote parsing logic**
I'm planning to copy the old footnote block but need to make adjustments for how we handle `content` and `indent_to_emit`. If we emit `indent_to_emit`, the `marker_text` should come from the original unstripped content to exclude any indent. I'll start by removing the FootnoteDefinitionParser from the dispatcher and updating imports as needed. The new footnote parsing block will be placed after dispatcher handling but before processing list markers to ensure it works correctly with interruptions. Additionally, I'll make sure we close paragraphs and footnotes where necessary, and carefully manage indentation within list items since they buffer raw lines. I’ll verify the expected behaviors in relevant functions as needed!*

### 💭 Reasoning
***Fixing footnote migration**
I need to address the broken footnote migration! The best approach seems to be reverting the footnote parser back to the old core logic. Although there was a desire to continue migrating, the summary suggests we can shift our focus to getting the tests to pass instead. My minimal change could involve removing the FootnoteDefinitionParser from the registry. This would allow us to restore the old block in core. Alternatively, I could implement a proper container approach with BlockEffect open/close. I need to weigh both options to find the smallest change that accomplishes our goal.**Managing footnote definitions**
In the dispatcher parse, starting the FOOTNOTE_DEFINITION node triggers a marker emission, and the core pushes the container while keeping the node open. The tricky part is figuring out how to close it. Currently, close_containers_to finishes generic containers, which would close the FootnoteDefinition when blank lines or indentation stop. I need to ensure that parse_prepared doesn’t finish the FOOTNOTE_DEFINITION node, but rather leaves it open. I’ll adjust parse_prepared to start the node and emit the necessary indentation to preserve formatting while handling stripped content in the indent emission.**Examining indentation handling**
When I pass ctx.content to the dispatcher, it’s stripped of content, but the builder still needs the original indentation tokens, especially if it’s within a container. For paragraphs and lists, the core emits indent_to_emit tokens before the markers. Now, if I’m parsing stripped content but need to give back the leading whitespace that got stripped, I’ll need to work on that. The fenced code block parser handles this well by using ctx.list_indent_info while still referring to the original lines. I'll check the parse_fenced_code_block method to see how it manages total indent and original line handling in the dispatcher.*

### 💭 Reasoning
***Fixing footnote handling**
Tests are failing, so I’m considering a minimal change: I could remove the incomplete dispatcher parser and restore the old core footnote parsing block by using try_parse_footnote_marker on stripped content. That would bring back previous functionality, which might be acceptable. Alternatively, I could implement a footnote opening effect similar to the fenced div, even though that’s a bigger change. The user mentioned deferring improvements to focus on migration, but footnotes are still important. So, I’ll go with reverting the changes for now until we can address this fully later.**Inspecting footnote handling**
I’m reviewing the current core, where the comment mentions that initial detection matches reference definitions, but footnotes are supposed to be handled later—though there's no explicit handling now. I’ll need to reintroduce explicit footnote parsing in the core, likely where the old code was. Footnote checks should happen before the dispatcher handles reference definitions. I realized the dispatcher has both FootnoteDefinitionParser and ReferenceDefinitionParser, so removing the footnote parser might keep the reference definitions. I want to ensure the footnote check works without the dispatcher consuming it, which means I’ll need to refine the setup.**Reviewing footnote checks**
In the previous code, checks for fenced code blocks were done before reference definitions. Now that the dispatcher handles those, it seems the footnote check should still happen before the dispatcher parses when appropriate. The challenge is that the dispatcher checks early and might parse other blocks before reaching the footnote check. Footnote definitions start with "[", and it looks like the dispatcher won’t match them due to how the reference definition parser is set up. Therefore, I’ll need to consider timing for this check in the core logic.**Implementing footnote checks**
I can insert the footnote check before the dispatcher handling, allowing it to interrupt paragraphs even without a blank line, thanks to the core logic. If a footnote marker is found, it closes the paragraph, which means we should detect the footnote before other list markers. However, we need to ensure it triggers correctly in both contexts, whether there's a blank line or not. This should respect the configuration for footnotes, so I’ll set it up similarly, considering indentation and losslessness when emitting the footnote marker.**Inserting footnote logic**
I’m thinking about where to insert the footnote logic. It seems logical to add it after the dispatcher block checks, but that wouldn't allow footnotes to interrupt paragraphs. The `parse_inner_content` handles blocks that require a blank line, but for footnotes, we need to recognize them regardless of that. So, I’ll check for footnotes after stripping the content but before dispatcher detection. I'll ensure that footnotes can be sequentially added and that any previous container is closed before starting a new one. Additionally, I’ll update the continuation policy and registry accordingly. Let's implement these changes!*

### 💭 Reasoning
***Addressing footnote migration**
I need to fix the current footnote migration issue. We can reinstate the old logic from e55bcc3 into the current core while either removing or adjusting the FootnoteDefinitionParser. We previously removed a special-case from the core and now have a dispatcher parser that emits footnote definitions but not the container. For now, it seems best to revert to the old handling. Given our constraints, the easiest solution might be to remove the FootnoteDefinitionParser and re-add the core block.**Implementing footnote handling**
I’m planning to implement a new approach similar to the old snippet in the current `parse_inner_content`, potentially inserting it before the reference definitions. Right now, we do have the `ReferenceDefinitionParser` in the dispatcher, but the core logic needs to allow for reference definitions from the dispatcher. It’s crucial to handle footnotes before the dispatcher. If we revert to the core, I’ll need to ensure the dispatcher doesn’t match footnotes, which means removing it from the registry. I'll consider keeping the structure but mark it as dead code to reduce confusion.**Adjusting footnote handling**
It looks like we removed the import for `reference_links` that the core currently uses. While we might not be using it right now, it will be needed for footnote marker parsing. I can utilize `try_parse_footnote_marker` from the `reference_links` module. Although the core imports the module, it doesn't import the specific function. I should call it directly or import it.
To replicate the old behavior adjusted for the current dispatcher system, footnote detection might need to happen before handling list markers and definitions, likely right after the dispatcher has had a chance.**Considering footnote handling logic**
I’m thinking about how footnotes interact with content that starts with a certain format; they shouldn't conflict with lists. However, we might need to consider the blank line rule because footnotes can interrupt paragraphs. In old code, it simply closed the paragraph and opened a footnote container, using the paragraphs module to handle the first line content.
The continuation lines are parsed normally since the stack has a `FootnoteDefinition` that handles indentation. There needs to be logic for closing the footnote based on line indentation, especially when encountering a blank line or closing containers.**Examining footnote closure logic**
I’m contemplating how footnotes should close when encountering less indent. If the next line has less indent, the current logic trims content but keeps the container open, which might cause issues with footnote continuation. The parser likely closes footnotes on a blank line, but maybe it should close on any non-indented line.
I need to check the earlier part of the core logic, particularly around how containers are closed when indentation changes. It looks like there’s only explicit closure on blank lines. However, footnotes need to end when a next unindented line appears, similar to how Pandoc handles them. I’ll search within older commits to find any relevant logic that addresses this properly.*

### 💭 Reasoning
***Analyzing footnote definitions and indentation**
I'm thinking about the logic of parsing lists and how changes in indentation affect blockquote depth. For footnote handling, I need to explore the Container::Definition in the current core, especially regarding blank lines and the content_indent function. It seems footnote definitions might close with a new footnote or at a blank line. Actually, in Pandoc, a footnote definition behaves like a list item and ends when a line is not indented enough, even without a blank line.**Investigating footnote parsing logic**
I’m considering if the parser closes FootnoteDefinition when it encounters a line that's not indented enough and isn’t blank. I suspect this might be in the compute_levels_to_keep function, which hasn't been used. I should check the old core for how list markers are handled. Also, I should explore how parse_inner_content manages indentation, especially since it's already stripped before being called. It seems like there might be a bug since tests have passed; I need to investigate further to see how closing works with footnotes and blockquotes.**Examining footnote closure logic**
I’m wondering if there’s a check for treating unindented lines as closing when inside a FootnoteDefinition container. I should search the old core for instances of matches!(Container::FootnoteDefinition) within parse_inner_content. I plan to explore the old code more closely after the indentation is stripped but before detection happens. To clarify things, I’ll use a git command to find relevant lines around "FootnoteDefinition" in parse_inner_content. This might help me identify any special checks that are needed.*

### 💭 Reasoning
***Considering footnote migration**
I’m looking into the fixed footnote migration. The simplest option seems to be reverting to the old core footnote handling and excluding the footnote parser from the dispatcher. However, it feels like footnotes should be handled explicitly, though there's no clear directive now.
I could revert the removal and implement footnote definition parsing in the core or integrate footnotes using BlockEffect, allowing for better container management. The user emphasized footnote migration as a top priority, so I want to ensure I handle it efficiently!**Evaluating footnote changes**
I'm considering minimal changes to achieve green status by reverting to the old core branch. I think we should keep the footnote parser but avoid double matching for now, which could mean removing it from the registry temporarily. The user had emphasized migrating blocks, so I want to ensure I implement the effect properly.
I'm looking at adding to the BlockEffect enum with OpenFootnoteDefinition. However, if I change the data storage, it may create ripples in how things operate—especially since the payload is consumed. I need a careful approach here.**Planning footnote handling**
I’m looking at how to store content_col, marker_end, and similar data in FootnotePrepared so that both the parser and core can downcast appropriately. The next step involves creating the OpenFootnoteDefinition effect.
In the parser, I'll start with setting the FOOTNOTE_DEFINITION node and emit the FOOTNOTE_REFERENCE token with the marker_text. I need to consider whether to use the original line or handle indentation. Since ctx.content already strips container indent, I want to ensure we maintain the necessary indent_to_emit for footnote definitions inside containers. It's important to preserve whitespace, so I need to look into how that’s currently handled for other dispatcher blocks.**Assessing indentation handling**
I’ve noticed that in the core, they compute stripped_content and indent_to_emit but don’t seem to emit indent_to_emit when passing to the dispatcher. This could impact the indentation inside definitions and footnotes, but tests for tables passed, suggesting that content_indent stripping might only apply in specific contexts.
Hmm, stripped_content removes leading indentation bytes, so it’s crucial to preserve those bytes. It appears they do this by emitting indent tokens before markers while parsing list markers and definitions. I think blocks like fenced code may handle indentation a bit differently, emitting whitespace tokens based on original lines.**Analyzing footnote closing logic**
I’m digging into how we handle footnotes, particularly with indentation and closing conditions. It seems that for HTML blocks, they likely use the full line, including whitespace. For footnote definition markers, I think we need to use the original line since ctx.content may be stripped.
The concern is about maintaining indentation correctly and ensuring that footnotes close appropriately. They may not close at a non-indented line without a blank line, which feels off. I suspect logic to close footnotes might have been overlooked, especially when indentation stops. I’ll need to confirm if that closing logic exists in parse_inner_content!**Investigating footnote migration and parser**
I want to check the current core for how parse_inner_content handles the Definition container, not specifically the Footnote container. It seems like the footnote container might not be in use, especially since tests passed before footnote migration.
After looking into the recent commit (c0672ae), it looks like the explicit footnote parsing may have been removed. I need to confirm if the commit history can show when footnote parsing was still in place.
It’s unclear if we are missing the necessary core semantics, especially in the ContinuationPolicy. I’ll check the code from older commits to see how they managed indent handling within footnotes!*

### 💭 Reasoning
***Considering footnote migration**
I realize that container closure relies on indentation and blank line policy. One option I’m exploring involves pushing containers in core when hitting footnote markers. I thought about extending BlockEffect, but that could complicate things since it's currently just an enum without payload. A simpler fix might be to move footnote definition parsing back to core, as the user previously wanted to focus on block migration, but footnote migration isn't fully done. Reverting could be a reasonable choice now.**Fixing footnote migration issues**
I realize that the conversation suggests wanting to continue the migration process, but right now, I need to address broken tests. Given that migrating footnotes necessitates container effects, it might be best to implement them now. I’m considering extending BlockEffect to include OpenFootnoteDefinition and CloseFootnoteDefinition, but since closing a footnote isn’t marker-triggered, it complicates things. The container needs to be pushed into the stack and closed at the right time to ensure everything works smoothly. The content lines should be parsed normally afterward.**Modifying dispatcher for footnotes**
I see that the dispatcher can’t access containers directly, so I’m thinking about mimicking the fenced div open parser. That parser starts a node and emits a child without pushing the container since core handles that later. I could define BlockEffect::OpenFootnoteDefinition and ensure it pushes the container while starting the node after parsing. The parser can initiate the FOOTNOTE_DEFINITION node and handle the marker, but it shouldn't finish the node, as it needs to wrap the subsequent content while the container is open.**Refining dispatcher for footnotes**
I see that in the dispatcher, parse_prepared is called when core starts parsing a block. This can lead to starting the FOOTNOTE_DEFINITION node and emitting the marker, which triggers the container push. To avoid mismatches, I must ensure that the container push occurs after starting the node. It seems fine for the builder to start the node and then finish it later. I’ll set it up to start the node, emit the marker token, and potentially begin a paragraph for the first line's content. However, I can't parse further content unless I'm in a parsing loop to handle indentation. Previously, core created paragraphs and appended content to a buffer for later parsing.**Rethinking footnote parsing strategy**
It’s clear that we need to manage indentation tokens carefully. The footnote line is content itself, so it should be parsed as part of the paragraph inside the footnote. I think we could buffer it by starting a paragraph and calling append_paragraph_line, but that needs a ContainerStack and builder, which I can't handle in the dispatcher.
Instead, I’m considering making changes to keep the footnote definition parsing in core for now, while also ensuring the dispatcher doesn’t improperly match and parse footnotes. This could mean rolling back migration and restoring the previous core logic while still maintaining some detection capabilities. I need to ensure the footnote parsing handles markers appropriately within the parsing flow, especially recognizing footnotes before other block types.**Implementing footnote parsing changes**
I'm planning to implement footnote parsing just after the dispatcher branch and before the list marker parsing. Since footnote lines can interrupt paragraphs without requiring a blank line, we should close any open paragraphs when a footnote marker is found. If another footnote definition is encountered, we need to close the previous one. To ensure proper buffering, I’ll call `prepare_for_block_element()` to flush the list item buffer and close any paragraphs.
Also, while emitting the footnote definition, I’ll need to consider retaining any whitespace for formatting, which I’ll include as WHITESPACE in the builder. When starting the FOOTNOTE_DEFINITION node, I’ll produce the marker text including the marker and any whitespace after it. This all needs to fit the existing structure without introducing errors, so I’ll aim to stay consistent with how previous markers were handled, ensuring that we properly manage the container stack.**Updating footnote parsing logic**
I'm thinking about adding footnote parsing logic after the dispatcher branch but before the list marker check. To ensure we preserve the indentation for footnote markers, I'll emit it as a WHITESPACE token before starting the FOOTNOTE_DEFINITION. I need to make sure that, in blockquote contexts, any relevant markers are emitted properly.
When encountering a new footnote definition while another one is open, I must close the previous one and the current paragraph. I’ll delete the unused FootnoteDefinitionParser from the dispatcher and ensure that the parsing logic integrates smoothly without causing any dead code warnings. After making these modifications, I’ll run the tests to confirm everything functions as expected.**Finalizing footnote logic changes**
Okay, so if I've emitted the `indent_to_emit`, the `content` will still be stripped, which is fine for both `marker_text` and `first_line_content`. I need to ensure that when I append `first_line_content` using `paragraphs::append_paragraph_line`, I preserve everything exactly, including any newline and trailing spaces.
If I've emitted the `indent_to_emit` as a WHITESPACE token, then `marker_text` must use the correct range as it relates to the original line. I’ll patch `core.rs` to make these adjustments, and I’ll also remove the FootnoteDefinitionParser from `block_dispatcher.rs`. Let’s proceed with these edits!*

I’m going to revert footnote definitions back to core (restoring the container semantics) and remove the incomplete dispatcher footnote parser, then run the test suite.

### 💬 Copilot
Footnote definitions can’t live in the dispatcher yet: they require **container semantics** (`Container::FootnoteDefinition { content_col }`) so their body can span multiple indented lines and nested blocks, which the dispatcher API currently can’t express.
I fixed the broken migration by:
- **Restoring footnote parsing in `core.rs`** (opening `FOOTNOTE_DEFINITION`, pushing `Container::FootnoteDefinition`, and parsing the first line content as paragraph content inside the container).
- **Removing `FootnoteDefinitionParser` from `block_dispatcher.rs`** (it was incorrectly emitting only a single-line node).
- Dropping the old “dispatcher must ignore footnotes” guard since the dispatcher no longer matches them.
`cargo test -q` is green.

### 💭 Reasoning
***Considering user input and plan updates**
I’m planning to propose an approach and ask the user for a decision using the ask_user tool. However, since ask_user is for input and I can't use plain text directly, I should include choices instead. I also need to view the plan first. It seems better to view the plan and ask the user simultaneously, then update the plan based on their input afterward, considering I can update based on our progress without waiting for user input.**Planning sequential updates**
I'm going to read plan.md first so I can then edit it to mark that the footnote migration has been reverted and outline the next steps for the dispatcher container effects. After that, I'll ask the user to choose the direction for the next work. This will require sequential tool calls since I'll need content from the view to make edits. I'll start with parallel calls for reporting intent and viewing the plan, then proceed with editing afterward.*

1. # Plan: Block dispatcher “prepared match” refactor
2.
3. ## Problem
4. Current `BlockParser::can_parse()` often does non-trivial work (e.g. fenced code parses fence + `InfoString::parse`, setext allocates, figure uses inline image parsing). This work is frequently repeated because:
5. - several parsers call `try_parse_*` again inside `parse()`
6. - `core.rs` calls `block_registry.detect(...)` multiple times per line in different branches
7. - `core.rs` separately re-implements “is this a block element marker?” checks (e.g. Definition continuation guard), further duplicating detection.
8.
9. ## Goal
10. Keep the good part of the refactor (Pandoc-like ordered registry + ability to “prepare/flush buffers before emitting”), while eliminating duplicate detection/parsing and reducing `core.rs` complexity.
11.
12. ## Approach (high level)
13. Introduce a **prepared match** concept: detection returns a match object that caches any expensive parsing results, and emission consumes that cached data (no re-parsing). Then rework `core.rs` so each line does **one** detection pass, decides whether the match is allowed (blank-line rules / interrupt rules), performs preparation, and emits.
14.
15. ## Key design decision (to confirm)
16. Two viable representations:
17. 1) **Trait objects + opaque payload** (recommended for minimal churn): registry remains `Vec<Box<dyn BlockParser>>`. Detection returns a `BlockMatch` containing a parser index + interrupt/blank requirements + `Box<dyn Any>` payload; emission downcasts payload.
18. 2) **Enum registry + typed payload** (slightly faster/cleaner types, but larger refactor): registry becomes `Vec<BlockParserKind>` and match payload becomes an enum.
19.
20. ## Workplan
21.
22. ### A. Baseline & safety
23. - [x] Run baseline tests/benchmarks to capture current behavior (`cargo test` at minimum).
24. - [ ] Identify a small set of “high-signal” golden cases to watch while refactoring (fenced code, setext, yaml/hrule ambiguity, refdefs).
25.
26. ### B. Introduce prepared-match API (non-invasive)
27. - [x] Add new types in `src/parser/block_dispatcher.rs`:
28. - `PreparedBlockMatch` (parser index + detection + cached payload)
29. - [x] Extend `BlockParserRegistry` with new entrypoints (keep old API temporarily):
30. - `detect_prepared(...) -> Option<PreparedBlockMatch>`
31. - `parse_prepared(match, ...) -> usize`
32.
33. ### C. Convert migrated parsers (start with biggest perf win)
34. - [x] Fenced code: detection parses fence + `InfoString` once; parse reuses cached `FenceInfo`.
35. - [x] ATX heading: detection returns cached level; parse uses it (no second `try_parse_atx_heading`).
36. - [ ] YAML: optionally cache “is yaml not hrule” disambiguation.
37. - [ ] Figure: cache validation span from inline image parse so it isn’t repeated.
38. - [x] Setext: remove allocation in detection (no `Vec`).
39. - [x] Reference definition: cache parse tuple from `try_parse_reference_definition` (payload currently unused by emitter).
40. - [x] Indented code: migrated into dispatcher (uses `has_blank_before_strict`).
41.
42. ### D. Refactor `core.rs` to “single detect per line”
43. - [x] Create one `BlockContext` per line and reuse it (avoid repeated rebuilds).
44. - [x] Replace the multiple dispatcher detections with one flow per line (detect once, then prepare/emit).
45. - [x] Rework the Definition continuation guard (`is_block_element` at ~1041) to delegate to the registry for migrated blocks (keeps special-cases for def/list/bq/html/tex).
46. - [x] Delegate nested-block marker probes (Definition continuation after blank line) to the registry instead of hardcoding fence/div/hrule checks.
47. - [x] Fix scattered continuation heuristics surfaced by indented-code migration (definition continuation + blank-line keep-open).
48.
49. Notes:
50. - `BlockContext` no longer stores `&ContainerStack` to avoid long-lived borrows blocking mutation during preparation/emission.
51.
52. ### E. Consolidate ordering/precedence in the registry
53. - [x] Migrate HTML blocks into the registry (interrupting).
54. - [x] Migrate LaTeX environment blocks into the registry (interrupting).
55. - [x] Migrate line blocks into the registry (interrupting).
56. - [x] Decide fenced-div integration approach (needs container-stack interaction), then migrate (Option 1: dispatcher emits + core mutates containers).
57. - [ ] Move remaining “block start” checks from `core.rs` into the registry progressively (tables, lists, etc.), keeping Pandoc ordering notes.
58. - [ ] Ensure special-case precedence rules stay correct (e.g., YAML vs hrule, setext vs hrule, list vs header edge cases).
59.
60. ### F. Cleanup
61. - [ ] Remove old `can_parse/parse` API once all migrated blocks use prepared matches.
62. - [ ] Remove redundant detection logic left in `core.rs`.
63. - [x] Consolidate definition/blank-line continuation heuristics into `ContinuationPolicy`.
64. - [ ] Run full test suite + clippy + fmt check.
65.
66. ## Notes / Constraints
67. - Maintain single-pass, lossless CST emission; prepared matches must not emit to the builder.
68. - Prepared payload should avoid borrowing `ctx.content` directly unless lifetimes are carefully managed; prefer storing indices / owned small strings only when needed.
69. - Performance expectation: dynamic dispatch/downcast overhead is negligible vs string scanning/allocs; eliminating repeated `InfoString::parse` etc. is the main win.
70.

### 💬 Copilot
We’ve hit the boundary between “leaf blocks” (easy to migrate) and “container blocks” (need core cooperation). Footnote definitions are container blocks: they must open a `Container::FootnoteDefinition` so subsequent indented lines + nested blocks are parsed inside it; the dispatcher can’t currently express “open a container and keep parsing inside it”.
Options to proceed:
1) **Keep container blocks in `core.rs` for now (recommended short-term)**
Continue migrating only leaf/self-contained blocks into the dispatcher (tables already done; plus remaining ones like hrule/headers/etc as applicable), and accept that lists/blockquotes/deflists/footnotes remain core-owned until we add container effects.
2) **Extend dispatcher with a general “container effect” API (recommended medium-term)**
Generalize what you did for fenced divs into something like:
- `BlockEffect::Open(ContainerKind { ... })` / `BlockEffect::Close(...)` (or a richer “transition”)
- core applies the effect (push/pop container), while the parser emits the opening marker node.
Then footnotes become a dispatcher parser that **emits only the marker line** + returns `OpenFootnoteDefinition { content_col: 4 }`; core pushes container and the rest flows naturally.
3) **Hybrid per-block hooks (not great)**
Let specific dispatcher parsers mutate core state via callbacks or passing `&mut ContainerStack` into parse. This breaks the nice separation and will get messy fast.
I updated `plan.md` to reflect that tables are migrated and footnotes are explicitly blocked on “container-opening effects”.

### 👤 User
We have problems with long-lived borrows and lifetimes in some other attempt previously, is this still a sound architectural choice?
---
<sub>⏱️ 808m 18s</sub>
### 💬 Copilot
Yes—*if* we keep the dispatcher side **pure/value-based** and apply container mutations in `core.rs`, this remains sound and avoids the long-lived borrow trap.
The key is: don’t let prepared payloads (or `PreparedBlockMatch`) hold references into `Parser` state (`&ContainerStack`, `&mut builder`, `&str` slices that outlive the call); instead store **owned or copy data** (e.g. `usize marker_end`, `content_col`, small owned strings if unavoidable), and have `parse_prepared()` return the normal “lines consumed” while `block_match.effect` (or a richer effect struct) carries the **container transition as plain data** for core to apply *after* emission.
That’s exactly why `BlockContext` intentionally does **not** store `&ContainerStack` today—so extending effects (like fenced divs) is the “safe” path, whereas passing `&mut Parser`/`&mut ContainerStack` into block parsers is what tends to resurrect lifetime/borrow headaches.

I see. You noted both 1 and 2 as recommended options?

***Evaluating tradeoffs**
I need to consider a tradeoff here: in the short term, it makes sense to keep changes within the core. However, in the medium term, I should implement container effects to provide clarity and enhance functionality. It's all about balancing immediate needs with longer-term goals for better outcomes. Let’s clarify what’s recommended to maintain effectiveness while planning ahead!*

1 is the **recommended next step right now** (keeps momentum, minimal risk): keep container-owned blocks (footnotes/lists/blockquotes/deflists) in `core.rs` and keep migrating leaf blocks into the dispatcher.
2 is the **recommended architectural destination** (unblocks migrating the hard blocks cleanly): add a general “open/close container” effect mechanism like fenced divs, but value-based (no borrows), so core owns the container stack while dispatcher owns ordered detection + marker emission.
So: do **1 now**, then implement **2 once you’re ready to migrate the next container-heavy block (footnotes or blockquotes/lists)**.

Okay, so what should we do next instead?

### 💭 Reasoning
***Considering migration options**
I'm weighing the next steps for the design and migration process. I could either implement a minimal generic effect and migrate footnotes first or postpone the migration and refactor to eliminate certain methods. There's a suggestion to deprecate legacy methods by defaulting them to newer methods. However, I also need to consider the impact on the parser trait and whether migrating specific components first would be the best path forward. I’m reflecting on what makes sense for maintaining code cleanliness!**Proposing architecture changes**
I see an opportunity to reduce duplication and clarify the architecture by removing `can_parse` and `parse` from the trait, keeping only `detect_prepared` and `parse_prepared`. This would involve adjusting the block registry to keep things consistent with the original goals. However, I also need to consider the user's earlier request to continue migrating blocks. Since I'm currently stuck on containers, I think it’s best to prioritize cleanup first and then move on to designing a generic container effect API!**Recommending next steps**
The user wants a discussion, but I can still suggest a clear next task. I recommend we remove the legacy `can_parse` and `parse` from the BlockParser trait and the registry. After that, we can focus on designing the generic container effects for footnotes, which keeps us on track for improving the architecture.*

Next I’d do a **cleanup pass**: remove the legacy `can_parse()`/`parse()` surface entirely and make the dispatcher API *only* `detect_prepared()` + `parse_prepared()` (this reduces duplication/confusion and makes future container work easier to reason about).
Then, once the surface area is smaller, we can implement **generic container effects** (a value-only `OpenContainer/CloseContainer` mechanism like fenced divs) and use footnotes as the first “container-migrated” block to validate the design.
This keeps progress moving without forcing us into lifetime-heavy designs or half-migrations again.
