# cratefield-cli (`fz`)
The venture CLI: `fz migrations collect`, `fz migrations apply`, `fz
data export` / `fz data import`, `fz doctor`, `fz modules`, `fz push`,
`fz auth import` (issue #650), `fz import supabase inspect` (issue #658),
the TypeScript client generator `fz client-ts` (issue #155), and the
agent-safe manifest workflow — `fz plan`, `fz deploy --plan`, `fz add`,
`fz init`, `fz verify` (harness #140).
`fz` links against your venture's compiled-in harness, so it runs as a bin
target **inside the venture repo** — the shape `fz build` generates for
every venture:
```toml
# venture Cargo.toml
[[bin]]
name = "fz"
path = "src/fz_main.rs"
[dependencies]
cratefield-cli = "0.1"
```
```rust,ignore
// venture src/fz_main.rs
fn main() { cratefield_cli::main_for(my_venture::harness); }
```
Then:
```sh
cargo run --bin fz -- migrations collect
cargo run --bin fz -- doctor
cargo run --bin fz -- modules
```
## `fz migrations collect [--dialect sqlite] [--out migrations]`
Walks the harness's modules in config order and writes
`migrations/<GGGG>_<module>_<NNNN>_<name>.sql` — the format
`wrangler d1 migrations apply` executes in lexical (apply) order.
`migrations/.harness-lock.json` pins `<module>/<migration-id>` to the
global file name plus a sha256 of its content:
- locked entries are never renamed or renumbered;
- new migrations append with the next `GGGG`;
- exits non-zero when a locked file is missing or was edited after being
applied (restore the file or add a new migration instead).
`--dialect postgres` for collect is not a thing: collect writes the
wrangler/D1 (sqlite) flow. Postgres migrations apply directly — see
`fz migrations apply` below.
## `fz migrations apply [--dialect postgres] [--fleet|--plan] --url <URL>`
Applies the harness's module migrations directly to a Postgres database
(issue #18): per module the `postgres` migration set when shipped, else
the `sqlite` set when it passes the portable-SQL lint, in lock order
(the order `migrations collect` pins), tracked idempotently in
`harness_migrations(id, applied_at)`. The native counterpart of
`wrangler d1 migrations apply`.
Requires building `fz` with the crate's `postgres` feature (so sqlx and
tokio stay out of the default, wasm-safe dependency graph):
```toml
[dependencies]
cratefield-cli = { version = "0.1", features = ["postgres"] }
```
```sh
cargo run --bin fz -- migrations apply --dialect postgres \
--url postgres://user:pass@host:5432/venture
```
### The fleet: `--fleet`, `--plan`, `--tenant`, `--strict`
Those flags point the same command at a **control** database — the one
holding the tenant registry — instead of a venture database, and
reconcile each registered tenant against its own database
(`docs/RECONCILIATION.md`, issue #30). `--url` therefore names a
different database with them than without, which is why nothing here is
implicit:
| `apply --url X` | the venture database | X's `harness_migrations` |
| `apply --fleet --url C` | the control database | each registered tenant's own database |
| `apply --plan [--tenant T] --url C` | the control database | nothing |
`--strict` turns a degraded tenant into a non-zero exit instead of
letting its neighbours serve, and needs `--fleet`. `--plan` with
`--fleet`, or `--strict` without it, is refused rather than guessed at.
`--fleet` against a registry with no tenants in it says so.
## `fz data export [--plan] --db <PATH> --out <FILE.jsonl>` / `fz data import [--append] [--plan] --url <URL> <FILE.jsonl>`
Moves a venture's D1 data to Postgres (issue #21). Export reads a
venture SQLite database — D1 is SQLite; the Cloudflare-side step is
`wrangler d1 export` loaded into a local file (`docs/DATA-MOVE.md` is
the whole runbook) — and writes one JSON Lines file: a manifest line
(per-table row counts and sha256, tables in lock order), then one
`{"table","row"}` record per row. `--plan` prints the per-table summary
without writing.
Import (built with the crate's `postgres` feature, like `migrations
apply`) loads that file into Postgres in lock order:
- every table's sha256 is verified against the manifest **before
anything is written** — a tampered or truncated file leaves the
target untouched;
- a non-empty table is refused without `--append` (naming the table and
the flag) before any write; `--append` adds to it, and overlapping
primary keys fail loudly rather than duplicating;
- inserts are batched multi-row statements inside one transaction per
table; values bind by the target column's Postgres type (typed NULLs
included), and the portable subset is TEXT/INTEGER/REAL/BOOLEAN —
anything else fails by name;
- after the writes, row counts are verified against the manifest;
- `--plan` prints the target's state (tables, incoming rows, existing
rows, refusal warnings) and writes nothing.
The manifest must be exactly this venture's tables — another venture's
export file is refused before anything touches the network.
## `fz tables diff --from <MANIFEST> [--to venture.json]`
What changed between two versions of a manifest's `[tables]` declaration,
and what each change costs — the same expand/contract/rewrite vocabulary
`fz tables drift` speaks.
This is the question **before** a deploy: *"I edited the declaration; can
I ship it?"* `drift` is the question after one. Neither answers the other,
and no database is involved in this one.
Both manifests are validated before they are compared, because
differences against a declaration that could never be deployed are
differences nobody can act on — and the reason it could not be deployed
is the thing worth saying.
**Exits non-zero when anything changed**, so a CI job comparing a
branch's manifest against `main`'s has something to branch on.
## `fz tables drift [--manifest venture.json] --dialect postgres --url <URL>`
What the database differs from the manifest's `[tables]` declaration by,
in the expand/contract/rewrite vocabulary `docs/ROLLBACK.md` §5 sets out.
Read-only: it opens the database, reads its catalog and prints. There is
no `--fix`, because what a drift costs is the author's decision and three
of the four answers are not "apply this".
**Exits non-zero when there is drift**, so a CI job asking "does this
database still match the manifest?" has an answer it can branch on rather
than a paragraph it has to read.
Two things it is careful about, both of which would otherwise produce
false reports:
- A database holds tables the declaration never named — the module
crates own tables too — and those are not the declaration's to remove.
- A catalog cannot see most of a declaration. `text`, `uuid`, `json`,
`enum` and `timestamp` are all `TEXT`; bounds, formats, enum members
and defaults are not recorded at all. The report ends with a line
naming exactly what was not compared, because "no drift" is an answer
about the things that *were*.
Needs an `fz` built with the `postgres` feature, like `fz migrations
apply`; a D1 database is read through wrangler rather than a connection
string.
## `fz doctor [--out migrations] [--json]`
Fails when:
- a module's `harness_api` differs from the `cratefield-core` it linked
against (the message names the module, its version and the core crate;
`Harness::build` already refuses this, the doctor re-asserts it —
issue #17);
- a module with `public_writes()` runs in a `production` venture without
the Captcha port (section 11);
- any module migration is not collected yet, a locked file is missing or
edited;
- a migration contains non-portable SQL: `AUTOINCREMENT`, `datetime(`,
`SERIAL`, `NOW()`, `json_extract`, or backtick quoting.
With `--json` the doctor speaks for agents (harness #140): exactly one
JSON object on stdout and nothing else —
```json
{"schema":1,"ok":false,"failures":[{"code":"locked-migration-edited","message":"…"}]}
```
`schema` is `1` today so consumers can branch; every failure carries a
`code` from the stable catalogue in `cratefield_cli::codes` — kebab-case,
never renamed or removed, while message wording may change. The exit code
still reflects the verdict; prose and operator warnings are unchanged
without the flag.
## `fz plan [--manifest venture.json] [--migrations migrations] [--json]`
The agent-safe workflow (harness #140) starts here. Reads the manifest,
the migration lockfile and the deploy record, and describes what would
change: modules added or removed (with each added module's catalog
tier, required modules, and whether a dependency pulled it in), venture
config deltas, migrations not yet collected, and the migration files a
removal would orphan. It changes nothing on disk.
The JSON carries `"schema": 1` and a **`digest`**: the sha256 over the
normalised destination state (venture identity, env, resolved modules,
per-module config, venture config, seed SQL, migration status). The
same inputs always give the same digest; any input change gives a
different one. The baseline-dependent deltas (added/removed lists) are
presentation, deliberately not hashed — an approval is of the
destination, not the journey.
## `fz deploy --plan <digest> [--manifest venture.json] [--i-am-deploying-to-production] [--i-am-removing-modules] [--json]`
Applies exactly the approved plan: recomputes it from the current
inputs and refuses any other digest — a stale approval cannot deploy
(`stale-plan`), and the refusal names what moved since the recorded
deployment.
Deploying without `--plan` at all is refused (`deploy-plan-required`):
approval is the point.
What "applies" means here is deliberate and bounded: `fz deploy`
records the plan, bound to its digest, in `.harness-deploy.json`
beside the manifest (written atomically, so an interrupted deploy
leaves either the old record or the new one and re-running
reconciles). It never runs wrangler, never compiles, and never
touches a database — the printed next steps (`fz migrations
collect`, `worker-build`, `wrangler deploy`) are needs-human and need
credentials `fz` does not hold. Running the same approved deploy
twice is safe: the second records nothing and reports
`changed: false`.
Two consents, deliberately separate:
- a venture whose manifest config resolves `ENV=production` refuses
without `--i-am-deploying-to-production`
(`production-deploy-unauthorized`);
- a plan that removes modules refuses without `--i-am-removing-modules`
(`destructive-change-unauthorized`). A removal stops serving those
modules and deletes no data: their tables, and the migrations that
created them, stay applied with their rows.
## `fz add <module> [--manifest venture.json] [--json]`
Adds a module to the manifest's desired composition and nothing else:
it never deploys, never provisions, never touches a database. The slug
must be in the catalog (`module-unknown` otherwise); adding a module
the manifest already lists is a no-op that succeeds with
`changed: false`. `.toml` manifests are rewritten as TOML, others as
JSON; comments and formatting are not preserved.
## `fz init --name <name> --host <host> [--manifest venture.json] [--force] [--json]`
Writes a new venture manifest — name and host, no modules yet. Refuses
to overwrite an existing manifest unless `--force`
(`manifest-exists`).
## `fz verify [--manifest venture.json] [--migrations migrations] [--json]`
Checks the recorded deployment still matches the manifest, reporting
drift as coded failures in exactly the doctor's JSON shape: the
module set (`composition-drift`), the config (`config-drift`), the
resolved environment (`env-drift`), and — when nothing narrower
explains it — the recorded digest no longer matching a recomputed
plan (`manifest-drift`). No deployment recorded at all is
`not-deployed`.
Every workflow command speaks both disciplines `fz doctor --json`
established: under `--json`, exactly one JSON object on stdout,
nothing on stderr, every failure carrying a stable code from the
catalogue; `--non-interactive` is accepted everywhere (the commands
never prompt — anything needing a human is a coded refusal, and the
flag suppresses the human `next:` steps from prose output).
## `fz push` (issue #184)
The operator side of the push transports. It reads the push environment
through `cratefield-push-wiring` — the one `build_push` that `serve()` and
`fz doctor` also call — so what `fz push` reaches is what the deployment
reaches, and no second place in the workspace names a push variable
(`crates/cli-acceptance/tests/push_env_guard.rs` fails the build if one
does). None of it needs a compiled-in harness, so the standalone `fz` (and
the Docker image) serve it too.
### `fz push vapid keygen [--file PATH] [--force] [--print-private]`
Generates the P-256 key pair Web Push identifies this application server by
and prints the **public** key — base64url of the 65-byte uncompressed point,
which is exactly what a browser passes to `pushManager.subscribe()` as
`applicationServerKey`.
- `--file` writes the private key, owner-readable only. Pipe it straight
into the secret: `wrangler secret put VAPID_PRIVATE_KEY < that file`.
- The private key is **never** printed without `--print-private`.
- An existing `--file` is not overwritten without `--force`, and both the
refusal and the `--force` run say what a rotation costs: every existing
browser subscription, none of which a server can recreate — each browser
has to subscribe again, with the user back on the site.
- Neither `--file` nor `--print-private` is refused: the run would keep no
private key, and the public half alone is useless.
A venture generates one of these once and keeps it forever.
### `fz push send --transport apns|fcm|web-push --recipient … --title … --body …`
Builds the venture's adapters from its environment and sends **one**
notification — the live-proof tool (issue #186) and the first thing support
runs. The report names the transport, a fingerprint of the recipient (never
the token, the endpoint or the `auth` secret), the transport's wiring
verdict, and then the outcome: `DELIVERED`, `FAILED` with the provider's
reason and what to do about it, or `NOT SENT` with the reason nothing was
routed.
`--recipient` is the bare device/registration token for `apns` and `fcm`,
and the browser's subscription JSON for `web-push` (`{"endpoint":…,
"keys":{"p256dh":…,"auth":…}}`, or the flattened form). Also `--data`,
`--url`, `--ttl`, `--priority` and `--silent`.
`--dry-run` reports which transport would carry the send and why, without
sending — it builds no HTTP client at all, so it cannot reach the network.
The send itself needs the crate's `push-send` feature, which pulls the
native runtime's HTTP client (reqwest behind the outbound policy) and the
tokio runtime it needs. That is a **separately installed binary**, never a
feature flipped on the venture's own dependency:
```sh
cargo install cratefield-cli --features push-send # a send-capable `fz`
```
`fz push` needs no compiled-in harness, so that binary — and the Docker
image, which is built with the feature — sends against any venture's
environment. Adding `features = ["push-send"]` to a venture's own
`cratefield-cli` dependency would instead pull `cratefield-runtime-native`
into the crate that also builds a wasm `cdylib`, and that crate
`compile_error!`s on wasm32: the venture would stop building for the target
it deploys to.
Without the feature every other `fz push` command still works, `--dry-run`
included, and `send` says exactly that in one line. That outbound policy
refuses loopback, private and link-local destinations, so a self-hosted push
service on a private network is refused by the client, not by the protocol.
### `fz push inspect-subscription <json>`
Validates a Web Push subscription with the adapter's own rules and prints
the `aud` it will sign for it — the push service's origin, never the
subscription's path, because a path-bearing `aud` is the commonest cause of
a VAPID `401`. Catches an endpoint that is not an absolute http(s) URL, a
`p256dh` that is not a 65-byte uncompressed P-256 point on the curve, and an
`auth` that is not 16 bytes.
## `fz auth import --target <URL> --admin-token-env <VAR> [--apply] [--merge-by-email] [--report <PATH>] [--batch-size N] <FILE.jsonl>` (issue #650)
Loads users into a running venture's `auth-core` module over its admin API:
one JSON object per line — `external_provider`, `external_id`, `email`,
`email_verified`, and optionally `password_hash`, `created_at`, `locale` —
blank lines skipped. The objects are passed through unchanged and sent to
`POST <target>/v1/auth-core/admin/users/import` in batches of `--batch-size`
(default 500, max 1000), behind `Authorization: Bearer <ADMIN_TOKEN>`: the
token is read from the environment variable `--admin-token-env` names, never
printed, and never a flag.
A **dry run by default**: the server validates every user and reports a
verdict without writing, and only `--apply` writes. A line that is not a JSON
object, or that misses a required field, and a duplicate
`(external_provider, external_id)` in the file are local errors reported with
their line number — the command aborts before sending anything.
It writes a report JSONL (default `<FILE>.report.jsonl`, or `--report`) with
one `{"external_provider","external_id","status","sub","reason"}` line per
user — never an email or a password hash — and prints a count per status. A
batch that cannot be sent, or a non-2xx reply, exits non-zero; a completed run
that reports `conflict` or `invalid` still exits zero, those being answers to
act on rather than transport failures.
Like `fz push send`, the network leg is behind an opt-in feature — a
send-capable `fz` is installed with `cargo install cratefield-cli --features
auth-import` — and without it the command says exactly that, because the
default `fz` graph carries no HTTP client and the feature pulls
`cratefield-runtime-native`, which `compile_error!`s on wasm32. `fz auth
import` needs no compiled-in harness, so the standalone `fz` runs it.
## `fz import supabase inspect --project <ref> [--json|--md] [--out FILE]` (issue #658)
Step one of moving a Supabase project onto the harness (ADR 0026): connects
**read-only** to the project's Postgres — and, with a token, the Supabase
Management API — and writes the migration report, every item automatic,
needs work or a blocker, with sizes and a transfer estimate. Markdown by
default, `--json` for the later steps and the dashboard. The database URL
comes from `SUPABASE_DB_URL` (or `--db-url`), the token from
`SUPABASE_ACCESS_TOKEN` (or `--management-token`); `fz` never prompts, never
prints them, and the report names the database by host and database only.
`--classify` asks the `TypeSafe` classifier (`TYPESAFE_API_KEY`) to label the
RLS policies no rule placed, advisory only. The exit code is non-zero for a
refused input, a connection or a permission error — never for a blocker.
The engine reads Postgres through sqlx, so it is behind a feature, for the
reason `push-send` is:
```sh
cargo install cratefield-cli --features import-supabase
```
Without it the command parses and says what to install. The whole guide —
the read-only role to create, how to read the report — is
`docs/import/supabase.md`.
## `fz build-key <manifest> [--catalog PATH]` (issue #59)
Computes the artifact's content address — sha256 over the pinned module
releases (slug, exact version, digest), the harness API, the rustc version and
the build profile — and prints it with the canonical inputs that produced it.
Runs no cargo, writes nothing. Module order in the manifest does not affect
the key; any module version, `harness_api`, rustc or profile change does. The
venture name, host, config and the sidecar mount table are deployment
configuration, not artifact content: two customers on the same module set
share the key and the artifact while keeping separate Workers, databases and
secrets, and one wasm serves customers whose `HARNESS_SIDECARS` differ. See
[docs/ARTIFACT-CACHE.md](../../docs/ARTIFACT-CACHE.md) for the guarantee.
## `fz client-ts --surface <PATH|-> --out <DIR> [--json]` (issue #155)
Generates the typed TypeScript client for a venture: a `/__surface`
contract document in, the files of a deterministic `@cratefield/client`
npm package out, written under `--out`. The document is what the running
venture serves — a path, or `-` to read it off stdin — so the client can
be generated without checking the venture out at all:
```sh
curl -s https://venture.example/__surface | fz client-ts --surface - --out ./client
```
`--out` is written over, not cleaned: the six generated files are replaced
in place and everything else already there is left alone — including older
files under `src/`, which `tsconfig.json`'s `include: ["src"]` will then
type-check and `package.json`'s `files` will ship. The composition hash
covers only the six written files, so generate into a directory that holds
nothing else.
Generation is deterministic: the same document generates byte-identical
files, and the summary prints the package name, the `sha256` composition
hash over them and the file list, so a regenerated client can be checked
against a published one before it ships. `--json` prints the same
verdict as exactly one JSON object on stdout — `schema`, `ok`, and
either the package, the hash and the files written or `failures` with
stable codes — with the exit code still reflecting the verdict. Like
`fz build` and the manifest workflow this command needs no venture
harness, so the standalone `fz` runs it.
## `fz modules`
Prints `name version /v1/<name> emits=[…] tables=[…]` per module.
## Applying migrations (wrangler)
Staging and production run the same commands from the venture repo:
```sh
# staging (first time / new migrations)
wrangler d1 migrations apply <database-name> --remote --env staging
# production
wrangler d1 migrations apply <database-name> --remote --env production
```
Locally: `wrangler d1 migrations apply <database-name> --local`.
