perf(startup): resolve brand & strict-mode without decrypting the app secret

Building the command tree resolved brand (auth login --domain help) and strict mode (per-command identity-flag registration via ResolveStrictMode) through f.Config(), which decrypts the app secret. On macOS that is a Keychain (securityd IPC) read on every invocation -- even --help/--version/ schema/completion, which never use the secret. brand and strict mode are plain config.json fields, so route them through a secret-free metadata path: - credential: add (*DefaultAccountProvider).ResolveMeta and a cached (*CredentialProvider).ResolveMeta returning brand + SupportedIdentities, via an optional metaResolver capability; external providers fall back to ResolveAccount (they do not touch the keychain). - cmdutil: ResolveStrictMode now uses ResolveMeta; add Factory.ConfigBrand. - auth login help text and shortcut registration read ConfigBrand. The app secret is still decrypted on demand when a command actually calls the API (auth status etc. unchanged). Measured on macOS (GOMAXPROCS=1): lark-cli --help 35.4ms -> 21.4ms (-40%); no behavior change on Linux/Windows (local secret backends are cheap).

 ### Structured errors in commands

-Command-facing failures must be typed `errs.*` errors — never the legacy `output.Err*` helpers and never a final bare `fmt.Errorf`. AI agents parse the stderr envelope's `type` / `subtype` / `param` / `hint` fields to decide their next action; the full taxonomy lives in `errs/ERROR_CONTRACT.md`.
-
-Picking a constructor:
-
-| Failure | Constructor |
-|---------|-------------|
-| User flag/arg fails validation | `errs.NewValidationError(errs.SubtypeInvalidArgument, ...).WithParam("--flag")` |
-| Valid request, wrong system state | `errs.NewValidationError(errs.SubtypeFailedPrecondition, ...).WithHint(...)` |
-| Lark API returned `code != 0` | `runtime.CallAPITyped` (shortcuts) / `errclass.BuildAPIError` (raw responses) — never hand-build |
-| Network / transport failure | `errs.NewNetworkError(errs.SubtypeNetworkTransport, ...)` |
-| Local file I/O failure | `errs.NewInternalError(errs.SubtypeFileIO, ...)` — validate the path first (`validate.SafeInputPath` / `SafeOutputPath`) and use `vfs.*` |
-| Unclassified lower-layer error as final | `errs.NewInternalError(errs.SubtypeUnknown, ...).WithCause(err)` |
-| Lower layer already returned a typed error | pass it through unchanged — re-wrapping downgrades its classification |
-
-Signatures that are easy to guess wrong:
-
- `runtime.CallAPITyped(method, url string, params map[string]interface{}, data interface{}) (map[string]interface{}, error)` — it performs the HTTP request itself and classifies `code != 0` into a typed error; just return the error it gives you.
- Typed pass-through check: `if _, ok := errs.ProblemOf(err); ok { return err }` — `ProblemOf` returns `(*errs.Problem, bool)`, not a nilable pointer.
- `.WithParam` exists only on `*errs.ValidationError`. `InternalError` / `NetworkError` have no param field — file or endpoint context goes in the message or `.WithHint(...)`.
-
-`forbidigo` + `lint/errscontract` reject the legacy `output.Err*` helpers, bare final `fmt.Errorf` / `errors.New`, and legacy envelope literals on migrated paths. Beyond what lint catches, three authoring conventions apply:
-
- Preserve the underlying error with `.WithCause(err)` so `errors.Is` / `errors.Unwrap` keep working.
- `param` names only the user input that actually failed. Recovery guidance goes in `.WithHint(...)`; machine-readable recovery fields (`missing_scopes`, `log_id`) carry server/system ground truth only — never caller-side guesses.
- Error-path tests assert typed metadata via `errs.ProblemOf` (`category` / `subtype` / `param`) and cause preservation, not message substrings alone.
+`RunE` functions must return `output.Errorf` / `output.ErrWithHint` — never bare `fmt.Errorf`. AI agents parse stderr as JSON; bare errors break this contract.

shanglei	3b6aa7dc6a	perf(startup): resolve brand & strict-mode without decrypting the app secret Building the command tree resolved brand (auth login --domain help) and strict mode (per-command identity-flag registration via ResolveStrictMode) through f.Config(), which decrypts the app secret. On macOS that is a Keychain (securityd IPC) read on every invocation -- even --help/--version/ schema/completion, which never use the secret. brand and strict mode are plain config.json fields, so route them through a secret-free metadata path: - credential: add (DefaultAccountProvider).ResolveMeta and a cached (CredentialProvider).ResolveMeta returning brand + SupportedIdentities, via an optional metaResolver capability; external providers fall back to ResolveAccount (they do not touch the keychain). - cmdutil: ResolveStrictMode now uses ResolveMeta; add Factory.ConfigBrand. - auth login help text and shortcut registration read ConfigBrand. The app secret is still decrypted on demand when a command actually calls the API (auth status etc. unchanged). Measured on macOS (GOMAXPROCS=1): lark-cli --help 35.4ms -> 21.4ms (-40%); no behavior change on Linux/Windows (local secret backends are cheap).	2026-06-10 17:46:03 +08:00
shanglei	ed63e12725	fix(registry): drop unused typedInitialized var; refresh OrderedProps doc typedInitialized was only assigned (in resetTyped) and never read, so staticcheck's U1000 (golangci `unused`) flagged it and would block the lint gate. Remove the field and its assignment. Also refresh the OrderedProps comment: the static-registry migration removed the meta_data.json natural-order machinery, so Order is now populated alphabetically (orderedKeys). The comment still claimed natural-order preservation. No behavior change.	2026-06-10 14:46:18 +08:00
shanglei	761aa55cbf	feat(registry): carry affordance through the typed registry The static-meta migration modeled only the method fields it explicitly declared, but the schema assembler still reads method["affordance"] to build _meta.affordance. metaschema.Method had no Affordance field and MethodToMap did not backfill it, so any method whose meta_data.json entry carries an affordance overlay would silently lose _meta.affordance in `schema --format json` (the embedded-JSON loader preserved it via the untyped map). Local meta currently has zero affordance entries, so no existing test caught it. Model affordance in the typed registry: - metaschema.Method gains Affordance plus Affordance/AffordanceExample types - gen.go emits the affordance literal (static, zero-alloc) - MethodToMap rebuilds method["affordance"] so parseAffordance keeps working schema JSON mode reads EmbeddedSpec (static baseline via ServiceToMap), which bypasses the remote overlay for determinism, so the remote/wire and MapToMethod paths -- never affordance consumers -- are left untouched. Add TestBuildMeta_AffordanceThroughTypedRegistry covering Method -> MethodToMap -> buildMeta -> _meta.affordance.	2026-06-10 14:13:56 +08:00
shanglei	2098c3c412	perf(registry): drop embedded meta_data.json and the larkmeta build tag The startup baseline now comes solely from the generated static Go registry (metastatic.Registry), wired into the stub-declared Registry via a package-level var plus an init() struct-header copy. No build tag, no committed generated file, and zero startup allocation is preserved. - gen.go emits a tag-free `var registryData` + `func init()` instead of a //go:build larkmeta top-level `var Registry`; stub.go declares Registry unconditionally so the package always compiles - fetch_meta.py regenerates the static registry after fetching, so every build and CI step that fetches also produces it (no separate gen step, no CI change) - remove the //go:embed meta_data.json baseline and the JSON parse fallback; meta_data.json is now only the build-time input to the generator - EmbeddedSpec/EmbeddedServiceNames read the static baseline; drop the schema key-order machinery so envelope field order is alphabetical (JSON Schema property order is not semantic; parameterOrder for positional args is intact) - drop -tags larkmeta from Makefile, .goreleaser.yml, and build-pkg-pr-new.sh Command tree is byte-identical (8092 lines). registry/schema/cmd unit tests, the zero-alloc bench, and the e2e dry-run suite all pass.	2026-06-09 18:36:58 +08:00
shanglei	4215ad9908	feat(registry): build command tree from static typed meta (larkmeta) Migrate the startup command-tree build path to read compile-time static Go structs (metastatic.Registry, behind -tags larkmeta) instead of parsing the 1.9MB meta_data.json into map[string]interface{} (~170K heap objects) on every invocation. - typed.go: typed baseline + remote-overlay layer. Reads static data under -tags larkmeta (zero parse / zero alloc); falls back to parsing the embedded meta_data.json once for builds without the tag (dev/test). A lazy typed->map shim (ServiceToMap/MethodToMap) keeps execution-path consumers working unchanged. - service.go: registration chain and NewCmdServiceMethod read typed structs directly; map wrappers convert via MapToService/MapToMethod for existing tests; method RunE materializes opts.Spec/opts.Method lazily, never at startup. - loader.go/remote.go: baseline and cached remote overlay decode into the typed shape; runtime refresh preserved. - build pipeline: Makefile, goreleaser and pkg-pr-new run the generator and build with -tags larkmeta so shipped binaries carry the static data. Reading the full static registry is 0 B/op, 0 allocs/op; the built command tree is byte-identical to the JSON-parsed tree (verified via a canonical tree dump in both modes).	2026-06-09 16:49:40 +08:00
shanglei	0b305a2248	feat(registry): typed meta schema + static-data generator (larkmeta tag) Render the embedded command spec as static Go data (metaschema types + metastatic generator and stub) to eliminate the startup JSON parse and allocation. Behind the larkmeta build tag; the runtime still uses the JSON path (not yet wired). A validation test confirms the static data matches the JSON parse (13 services / 70 resources / 215 methods / 4233 fields) and that reads allocate nothing. Generated meta_data_gen.go is gitignored, like meta_data.json.	2026-06-09 15:37:30 +08:00
