<instructions>
Classify this git diff into conventional commit format. Ground every choice in the diff, stats, and supplied context only. Prefer conservative classifications over speculation.
## 1. Determine Scope
Apply scope only when one component clearly dominates the semantic change or roughly 60%+ of line changes:
- 150 lines in src/api/, 30 in src/lib.rs -> `api`
- 50 lines in src/api/, 50 in src/types/ -> (none)
Use no scope for cross-cutting changes, evenly split changes, project-wide refactoring, or any case where the best scope would be vague.
Prefer scopes from `<common_scopes>` and `<scope_candidates>` over inventing new ones. Only invent a scope if no candidate fits.
Scope MUST be short — ideally one word, max two words joined by `-`. If a candidate is long (e.g. `coding-agent-chunk-edit-protocol`), shorten it to the most distinctive segment (e.g. `chunk-edit`). Never use 3+ hyphenated words.
Forbidden scopes: `src`, `lib`, `include`, `tests`, `benches`, `examples`, `docs`, project name, `app`, `main`, `entire`, `all`, `misc`.
If unsure, omit scope rather than a weak or misleading one.
## 2. Generate Summary
The summary is the description part after `type(scope):`.
The summary:
1. Starts with a lowercase past-tense verb
2. Is an umbrella headline for the whole changeset
3. Synthesizes the shared behavior or outcome across the diff and details
4. Does not copy detail #1 or focus on one narrow file unless it dominates
5. Has no `type(scope):` prefix, no trailing period, and no markdown
6. Fits the configured summary guideline (normally ≤72 characters including prefix)
## 3. Generate Details (0-6 items)
Return only the highest-signal 0-6 details.
Each detail:
1. Past-tense verb, ends with period
2. Explains impact/rationale (skip trivial what-changed)
3. Uses precise names (modules, APIs, files)
4. Under 120 characters
Group 3+ similar changes into one detail. Exclude import changes, whitespace, formatting, trivial renames, debug prints, comment-only changes, and file moves without meaningful modification.
## 4. Assign Changelog Metadata (when user-visible)
- New public API, feature, capability → Added
- Modified existing behavior → Changed
- Bug fix, correction → Fixed
- Feature marked for removal → Deprecated
- Feature/API removed → Removed
- Security fix or improvement → Security
## 5. Verify Before Finalizing
Before responding, check that:
- `type` matches the dominant change and is one of the allowed commit types.
- `scope` is either a valid short scope or omitted.
- `summary` is an umbrella headline, starts with a past-tense verb, and has no prefix or period.
- `details` are complete, grounded, and within the 0-6 limit.
- `issue_refs` only contains references supported by the diff/context.

<output_format>
You MUST return the result in this format WITHOUT the fences:
```
# type(scope): summary
- detail 1
- detail 2
- detail 3
Fixes: #123, #456
```
