* refactor: add output emitter contract and differential harness
Introduce a leaf Emitter in internal/output that composes the existing
output primitives (content-safety scan, envelope, jq, format rendering,
notice) behind a single command-scoped port. The emitter is unwired: no
production caller is migrated, so CLI output stays byte-for-byte unchanged.
A differential test harness drives the real legacy entry points
(RuntimeContext.Out/OutRaw/OutFormat/..., WriteSuccessEnvelope and the
pagination formatter) and asserts byte-identical stdout/stderr plus typed
errors, locking behavior before later slices migrate callers.
* refactor: tighten emitter API and cover pagination with real tests
- split Emitter.Success/PartialFailure and drop EmitOptions.OK so a
missing ok flag can no longer silently emit ok:false
- give StreamPage its own StreamOptions (format + pretty) instead of
reusing EmitOptions, making "jq needs aggregation" a compile-time fact
- pin the Emitter jq-error contract (returns error, writes no stderr);
the caller adapter re-emits the legacy stderr line on migration
- add in-package tests driving the real apiPaginate/servicePaginate over
a mock transport: multi-page aggregation, empty-result fallback,
MarkRaw handling, and the business-error raw-response red line
* test: use standard TestFactory harness for pagination tests
Replace the hand-rolled RoundTripper + APIClient construction in the
apiPaginate/servicePaginate tests with cmdutil.TestFactory and its
httpmock.Registry, and isolate LARKSUITE_CLI_CONFIG_DIR to t.TempDir(),
matching the repo's standard HTTP-mocked test convention. Assertions and
coverage (multi-page aggregation, empty-result fallback, MarkRaw, and the
business-error raw-response red line) are unchanged.
* refactor: route success output through the single Emitter port
Migrate the success-output surfaces onto internal/output's Emitter,
byte-for-byte identical (proven by frozen golden diffs and the real
paginate/HandleResponse tests):
- RuntimeContext.Out/OutRaw/OutFormat/OutFormatRaw/OutPartialFailure now
build an Emitter and call Success/PartialFailure; emit and outFormat are
removed. An adapter maps the returned error back to the legacy
outputErrOnce / jq-error stderr / exit-code behavior.
- WriteSuccessEnvelope degrades to a thin Emitter.Success delegate; its 8
callers are unchanged.
- apiPaginate/servicePaginate stream pages via Emitter.StreamPage; the
aggregate and business-error raw-response branches are untouched.
- HandleResponse routes its non-JSON structured-response branch through
Emitter.Success.
Frozen golden fixtures replace the runtime legacy oracles so the
differential harness cannot go self-referential after migration.
* fix: keep _notice on struct payloads in Emitter's unknown-format fallback
printLegacyDataJSON now normalizes via toGeneric first (matching FormatValue), so a struct / named-map payload retains its injected _notice on the unknown-format -> JSON fallback rather than dropping it silently. Add a regression test that fails against the pre-fix path.
* refactor: make the Emitter own write failures and stop mutating inputs
Route every Emitter stdout path through a render-to-buffer-then-copy helper so a marshal/render failure leaves stdout empty and surfaces a typed internal error (with cause), and a stdout write failure is propagated instead of silently swallowed. Leaf writers gain error-returning Write* cores; the legacy Print*/FormatValue wrappers keep their exact behavior for unmigrated callers.
- handleEmitterError now captures every error, not only the jq/safety branches; flip OutRaw's write-error test to assert propagation.
- Clone the map before injecting _notice so a caller's payload is never mutated and an existing _notice is never overwritten.
- Preserve jq's own typed error (validation/api) on a bad expression or runtime failure; only wrap genuine stdout write failures.
- Split tests: normative emitter_contract_test.go vs frozen emitter_legacy_compat_test.go (base SHA recorded, self-update env vars removed).
* fix: satisfy license-header and forbidigo lint on the emitter changes
- Move the base-SHA note below the copyright header in the renamed legacy-compat test so the license-header check sees a valid header at the top.
- Route the leaf wrappers' marshal/format stderr messages through a single legacyStderrf helper (one //nolint:forbidigo) instead of bare os.Stderr, preserving exact legacy behavior for unmigrated direct callers while passing forbidigo; drop the now-unused os imports.
* fix: stop legacy CSV wrappers reporting write failures to stderr
Align FormatAsCSV/FormatAsCSVPaginated and FormatValue/FormatPage's CSV branch with the other leaf wrappers: report only marshal failures, swallow write failures. Previously they emitted a 'csv write error' for the (empty) line and the JSON-fallback write failures that the pre-refactor code ignored, and mislabeled a JSON write failure as a CSV one. Failure-path only; success output is unchanged (golden double-diff still byte-for-byte).
* refactor: retire legacy error envelopes and enforce typed contract
Consolidate all command error reporting onto the typed errs.* contract, remove
the legacy error surface that predated it, and tighten the lint guards so the
contract holds across the whole repository going forward.
Every failure now reaches stderr as one envelope shape: a category, an
optional subtype, a human- and agent-readable message, and a recovery hint,
with invalid parameters listed under `params`. The legacy ExitError envelope,
its constructors, and the boundary bridge that promoted untyped config and
authorization errors are deleted, leaving a single path from error to wire.
Predicate commands keep their silent-exit behavior through a dedicated signal
that carries only an exit code.
Infrastructure paths that still emitted ad-hoc envelopes — flag parsing,
unknown commands and subcommands, plugin and policy guards, confirmation
prompts, and auth/config failures — now classify into the same taxonomy.
Business, API, auth, and config exit codes are preserved; the one behavioral
change is that Cobra usage failures (missing required flag, unknown command,
bad arguments) now emit the typed validation envelope and exit 2, matching the
explicit flag and subcommand guards, instead of Cobra's plain-text exit 1.
Enforcement is repo-wide rather than per-path:
- The errscontract guards run by default everywhere instead of through a
migration allowlist, so legacy envelopes cannot be reintroduced anywhere.
- errorlint runs across the whole repository: every error wrap must use %w and
every comparison must use errors.Is/errors.As, so interior wraps stay legal
but can no longer break the chain the typed boundary relies on.
- The errs-no-bare-wrap guard is keyed by structural prefix instead of an
explicit per-domain allowlist, so new shortcut domains are covered without
editing a list. It runs where forbidigo is enabled (the shortcut domains and
the auth/config/service command groups); repo-wide chain integrity for the
remaining command paths is carried by errorlint above.
* test: align cli_e2e success assertions to the ok envelope
The api and service success path now emits the {"ok":true} envelope, so the
cli_e2e workflow assertions that still expected the old {"code":0} shape via
AssertStdoutStatus(t, 0) fail once they run with live credentials. Switch those
workflow assertions to AssertStdoutStatus(t, true); the fake-payload helper test
in core_test.go keeps its code-shape assertion.
Every failure on the authentication, authorization, and configuration
path now surfaces as a typed structured error instead of an ad-hoc
envelope. Users and scripts that consume CLI output get:
- a fixed nine-category taxonomy on the wire, each mapped to a
stable shell exit code (authentication/authorization/config = 3,
network = 4, internal = 5, policy = 6, confirmation = 10)
- identity-aware detail fields (missing_scopes, requested_scopes,
granted_scopes, console_url, log_id, retryable, hint) carried
uniformly on the envelope
- a single canonical policy envelope at exit 6; the legacy
auth_error carve-out is retired
- per-subtype canonical message + hint that preserves Lark's
diagnostic phrasing and routes recovery to the right actor:
app developer (app_scope_not_applied), user (missing_scope,
token_scope_insufficient, user_unauthorized), or tenant admin
(app_unavailable, app_disabled)
- wrong app credentials classify as config/invalid_client whether
surfaced by the Open API endpoint (99991543) or the tenant
access-token mint endpoint (10003 / 10014), instead of
collapsing to a transport error or api/unknown
- local shortcut scope preflight emits the same
authorization/missing_scope envelope (identity + deterministic
missing-scope set) used by the post-call permission path, so AI
consumers read the same structured shape from precheck and from
server-returned permission denial
- streaming download/upload failures keep the same network subtype
split (timeout / TLS / DNS / transport) as the non-stream path
instead of collapsing every cause to a generic transport failure
- console_url is carried only on the bot-perspective
app_scope_not_applied envelope (where the recovery action is
"developer applies the scope at the developer console"); the
user-perspective missing_scope envelope drops the field, since
the only actionable user recovery is `lark-cli auth login --scope`
and pointing an end user at a console they cannot modify is
misleading
- bind workflows (Hermes / OpenClaw / lark-channel) flatten dynamic
Type tags to wire 'config' with the original module name kept
as a metric label
All 10 typed errors are cause-bearing, nil-safe on .Error() and
.Unwrap(), and defensively clone slice setter inputs. Four lint
rules (CheckNilSafeError / CheckBuilderImmutable / CheckUnwrapSymmetry
/ CheckBuildAPIErrorArms) lock these invariants on migrated paths.
Introduce a typed error contract framework for lark-cli so in-process
Go callers can branch via errors.As(&errs.XxxError{}) and shell scripts,
AI agents, and protocol adapters can branch on stable JSON type/subtype
fields instead of regex-parsing free-form messages.
Adds:
- Canonical taxonomy under errs/ (9 categories + typed Error structs
embedding a shared Problem, RFC 7807-aligned)
- Centralized Lark code metadata + identity-aware BuildAPIError dispatch
- Typed JSON envelope writer alongside the legacy envelope writer
- MCP / OAuth (RFC 6750 Bearer) projection adapters
- Five CI lint guards preventing ad-hoc taxonomy drift
Backward compatibility: legacy *output.ExitError producers (ErrAPI,
ErrWithHint, Errorf, ErrBare) and business shortcuts that use them
continue to render the legacy envelope unchanged. SecurityPolicyError
wire format and exit code are preserved via a carve-out; taxonomy
migration is deferred to PR 2. Domain-specific business migration is
staged across PR 3+.
Framework-direct paths now return typed *errs.*Error: ErrAuth /
ErrValidation / ErrNetwork emit category literals on the wire
(authentication / validation / network), *core.ConfigError is promoted
at the cmd/root boundary with exit code aligned from 2 to 3, and Lark
API permission denials classified by BuildAPIError exit 3.
At the SDK boundary, WrapDoAPIError preserves any already-classified
error (legacy *output.ExitError or typed *errs.*) so output.ErrAuth
from missing credentials surfaces with the auth category and exit 3
intact instead of being downgraded to a network error. Policy responses
classified by BuildAPIError (codes 21000 / 21001) extract challenge_url
and the canonical hint from the response body, matching what the
auth transport already surfaces at the HTTP layer; non-https
challenge URLs are dropped.
First PR in the feat/error-contract-* series.

* feat: add --jq flag for filtering JSON output across all command types
Add jq expression filtering (--jq / -q) to api, service, and shortcut
commands using gojq. Includes early expression validation, mutual
exclusion checks with --output and non-json --format, pagination+jq
aggregation path, and comprehensive test coverage.
* fix: correct gofmt alignment in jq_test.go struct literal
* fix: downgrade gojq to v0.12.17 to keep Go 1.23 compatibility
gojq v0.12.18 requires Go 1.24, which unnecessarily bumped the project
minimum version. v0.12.17 requires only Go 1.21 and provides the same
jq functionality needed.
* refactor: consolidate jq validation and pagination logic
Extract ValidateJqFlags() and PaginateWithJq() shared functions to
eliminate duplicated jq logic across api, service, and shortcut commands.
* fix: reject --jq for non-JSON responses and propagate shortcut jq errors
- HandleResponse now returns a validation error when --jq is used with
a non-JSON Content-Type instead of silently falling through to binary save.
- Shortcut runtime jq errors are captured in RuntimeContext.outputErr
and propagated as the command exit code, matching api/service behavior.
