* 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).
