Register approval.instance.status_changed_v4 and approval.task.status_changed_v4 with custom flattened schemas and user-auth pre-consume subscription setup.
Handle approval subscription_type as optional multi-value pre-registration metadata: omitted values register both involved and managed relations, explicit values can be single, comma-separated, or JSON array, and consumers do not unsubscribe on exit.
Report partial approval subscription registration failures with registered and failed relation context while preserving the underlying typed error classification.
Document approval event output fields and subscription semantics, and refresh approval skill references from API metadata.
This PR improves the im.message.receive_v1 event output by exposing structural
metadata fields (reply context, sender type, mentions) that were previously only
available in the raw V2 envelope. It also syncs the same structural fields to the legacy
+subscribe --compact pipeline.
Add support for card.action.trigger, the event fired when a user interacts with an
interactive card (button click, form submit, dropdown, checkbox, input, date picker, etc.).
The handler flattens the V2 envelope into a structured output and auto-fetches the original
card content (card_content) at consume time, enabling a complete read-then-update workflow
without extra API calls.
Previously, im.message.receive events with message_type: interactive surfaced the raw JSON
payload as content, requiring callers to manually parse the card schema. This PR introduces a
user_dsl renderer (ConvertInteractiveEventContent) that converts interactive card content into
structured human-readable text — consistent with how text, post, image, and other message
types are already handled.
The output format is <card title="..." subtitle="...">...</card>, with each card element type
serialised to a readable representation (markdown body, button links, table rows, chart summaries,
etc.).
Framework support for resource-scoped event subscriptions, so one
EventKey can fan out into independent per-resource subscription scopes:
- KeyDefinition gains SubscriptionKey / NormalizeParams / Match hooks
- ComputeSubscriptionID derives a dedup identity from (EventKey, sub-key
params); plumbed through bus Hub, consume loop, and the
Hello / PreShutdownCheck / ConsumerInfo protocol messages
- add a synchronous Match filter stage before Process
- change PreConsume cleanup to func() error and surface cleanup
(unsubscribe) failures as WARN with an idempotency note
- adapt minutes/vc/whiteboard PreConsume to the new cleanup signature
- render SubscriptionID / SubscriptionKey in event status & schema output
No domain wires these hooks yet; covered by unit tests using bus/protocol
doubles. (Mail, the original exerciser, is intentionally not included.)

Replace every command-facing error path in the event domain — the
consume/schema command layer, the +subscribe shortcut, EventKey
definitions, and the consume orchestration — with typed errs.*
envelopes, so consumers get stable type, subtype, param, hint, and
missing_scopes metadata for classification and recovery instead of
free-form message text.
- Input validation (--jq, --param, --output-dir, --filter, --route,
unknown EventKey, EventKey params) reports validation /
invalid_argument with the offending flag in param and an actionable
hint.
- Scope preflight reports authorization / missing_scope with the
machine-readable missing_scopes list; console-subscription and
single-bus preconditions report failed_precondition with recovery
hints.
- The consume API boundary passes already-typed errors through and
classifies transport, non-JSON HTTP, and unparsable responses; the
vc note-detail retry now matches the not-found code on typed errors
(it silently never fired against the legacy envelope shape).
- Previously-bare failures exited 1 with a plain-text "Error:" line
and now exit with their category code (validation 2, auth 3,
network 4, internal 5) alongside the typed stderr envelope.
- forbidigo and errscontract guards now cover the event paths so
regressions fail lint; AGENTS.md and the lark-event skill document
the typed contract for agent consumers.
Validation: make unit-test (race) green; event unit and e2e suites
assert category/subtype/param/hint and cause preservation against the
real binary; errscontract and golangci lint clean.
Wire the board.whiteboard.updated_v1 EventKey into the consume pipeline so that lark-cli event consume automatically calls the per-whiteboard subscribe / unsubscribe OAPIs instead of requiring callers to manage server-side subscriptions out-of-band.

* feat(event): add event subscription & consume system with orphan bus detection
Introduces end-to-end Feishu event consumption via a new `lark-cli event`
command family. Users can subscribe to and consume real-time events
(IM messages, chat/member lifecycle, reactions, ...) in a forked bus
daemon architecture with orphan detection, reflected + overrideable JSON
schemas, and AI-friendly `--json` / `--jq` output.
Commands
--------
- `event list [--json]` list subscribable EventKeys
- `event schema <key>` Parameters + Output Schema + auth info
- `event consume <key>` foreground blocking consume; SIGINT/SIGTERM
/stdin-EOF shutdown; `--max-events` /
`--timeout` bounded; `--jq` projection;
`--output-dir` spool; `--param` KV inputs
- `event status [--fail-on-orphan] [--json]` bus daemon health
- `event stop [--all] [--force] [--json]` stop bus daemon(s)
- `event _bus` (hidden) forked daemon entrypoint
Architecture
------------
- Bus daemon (internal/event/bus): per-AppID forked process that holds
the Feishu long-poll connection and fans events out to 1..N local
consumers over an IPC socket. Drop-oldest backpressure, TOCTOU-safe
cleanup via AcquireCleanupLock, idle-timeout self-shutdown, graceful
SIGTERM.
- Consume client (internal/event/consume): fork+dial the daemon,
handshake, remote preflight (HTTP /open-apis/event/v1/connection),
JQ projection, sequence-gap detection, health probe. Bounded
execution (`--max-events` / `--timeout`) for AI/script usage.
- Wire protocol (internal/event/protocol): newline-delimited JSON
frames with 1 MB size cap and 5 s write deadlines. Hello / HelloAck /
PreShutdownCheck / Shutdown / StatusQuery control messages.
- Orphan detection (internal/event/busdiscover): OS process-table scan
(ps on Unix, PowerShell on Windows) with two-gate cmdline filter
(lark-cli + event _bus) that naturally rejects pid-reused unrelated
processes.
- Transport (internal/event/transport): Unix socket on darwin/linux,
Windows named pipe on windows.
- Schema system (internal/event, internal/event/schemas): SchemaDef with
mutually-exclusive Native (framework wraps V2 envelope) or Custom
(zero-touch) specs. Reflection reads `desc` / `enum` / `kind` struct
tags, with array elements diving into `items`. FieldOverrides overlay
engine addresses paths via JSON Pointer (including `/*` array
wildcard) and runs post-reflect, post-envelope. Lint guards orphan
override paths.
- IM events (events/im): 11 keys — receive / read / recalled, chat and
member lifecycle, reactions — all with per-field open_id / union_id /
user_id / chat_id / message_id / timestamp_ms format annotations.
Robustness
----------
- Bus idle-timer race fix: re-check live conn count under lock before
honoring the tick; Stop+drain before Reset per timer contract.
- Protocol frame cap: replace `br.ReadBytes('\n')` with `ReadFrame` that
rejects frames > MaxFrameBytes (1 MB). Closes a DoS path where any
local peer could grow the reader's buffer unbounded.
- Control-message writes gated by WriteTimeout (5 s) so a wedged peer
kernel buffer can't stall writers indefinitely.
- Consume signal goroutine: `signal.Stop` + `ctx.Done` select, no leak
across repeated invocations in the same process.
- JQ pre-flight compile so bad expressions fail before the bus fork and
any server-side PreConsume side effects.
- `f.NewAPIClient`'s `*core.ConfigError` now passes through unwrapped
so the actionable "run lark-cli config init" hint reaches the user.
Subprocess / AI contract
------------------------
- `event consume` emits `[event] ready event_key=<key>` on stderr once
the bus handshake completes and events will flow. Parent processes
block-read stderr until this line before reading stdout — no `sleep`
fallback needed.
- All list-like commands have `--json` for structured consumption.
- Skill docs in `skills/lark-event/` (SKILL.md + references/) brief AI
agents on the command surface, JQ against Output Schema, bounded
execution, and subprocess lifecycle.
Testing
-------
Unit tests across bus/hub, consume loop, protocol codec, dedup,
registry, transport (Unix + Windows), schema reflection, field
overrides, pointer resolver. Integration tests cover fork startup,
shutdown, orphan detection, probe, stdin EOF, preflight, bounded
execution, and Windows busdiscover PowerShell compatibility.

* fix(event): address CodeRabbit findings + lift patch coverage above 60%
CodeRabbit comments (PR #654)
-----------------------------
1. bus/dedup: IsDuplicate dropped legitimate (post-TTL) events after
cleanupExpired fired. The run-every-1000-inserts cleanup removed
TTL-expired IDs from the `seen` map but left them in the ring;
IsDuplicate's ring-scan fallback then rediscovered them and falsely
reported "duplicate", and bus.Publish silently dropped the event.
Removed the ring-scan branch — `seen` is the sole authority, the ring
only bounds map size via overflow eviction. New regression test
TestDedupFilter_TTLExpiryAfterCleanupRunRespected exercises the 10-
insert + cleanup path and guards the fix.
2. consume/remote_preflight: the decoder only read `data.online_instance_
cnt`. A non-zero business code with no data payload decoded to 0 and
callers treated it as "verified zero", forking a local bus that would
duplicate events. Added Code / Msg fields and promoted code != 0 into
an error so the caller distinguishes verified-zero from check-failed.
3. cmd/event/stop: swapped os.ReadDir / os.Stat to vfs.ReadDir / vfs.Stat
in discoverAppIDs per project guideline (enables test mocking). New
TestDiscoverAppIDs_* lifts discoverAppIDs from 0% to 100%.
4. cmd/event/appmeta_err: narrowed authURLPattern from
feishu.cn|feishu.net|larksuite.com|larkoffice.com to the two hosts
consoleScopeGrantURL actually produces. Kept the allowlist pinned to
ResolveEndpoints' output with a comment flagging the synchrony.
5. cmd/event/list: moved "No EventKeys registered." and "Use 'event
schema <key>' for details." hints to stderr so `event list | jq`
style pipelines don't ingest them as data.
6. cmd/event/schema: runSchema is a RunE entry point; swapped the bare
fmt.Errorf on resolveSchemaJSON failure to output.Errorf so AI
agents parse a structured error envelope.
Coverage bumps (patch ~50% -> ~60%)
-----------------------------------
internal/event/consume/loop_test.go: loop.go was 0% at patch time.
New tests cover consumeLoop end-to-end via net.Pipe (events -> sink,
max-events -> ctx.Done -> PreShutdownCheck/Ack), seq-gap warning,
jq filtering + early compile failure, isTerminalSinkError classifier.
Takes consumeLoop from 0% to ~74%.
internal/event/protocol/messages_test.go: all NewXxx constructors,
Encode/Decode roundtrip per message type, EncodeWithDeadline deadline
enforcement, ReadFrame MaxFrameBytes rejection + EOF propagation.
Takes protocol from 28% to ~86%.
Also bundles small UX polish:
- cmd/event/consume: --output-dir flag doc flags path-traversal behavior;
jq-validation failures now re-wrap with an event-specific hint
pointing at `event schema` for payload shape.
- internal/event/consume.validateParams: error now names the EventKey
and lists valid param names inline so AI callers recover without a
second `event schema` round-trip.
- skills/lark-event: description expanded to mention
listener/subscribe/consume synonyms + the IM scope set explicitly;
lark-event-im reference polished; obsolete lark-event-subscribe
reference removed.
Verified with go test -race -timeout 120s across ./cmd/event/...,
./events/..., ./internal/event/...; gofmt clean; go vet clean.

* test(event): cover format helpers + cobra factories
Adds cmd/event/format_helpers_test.go covering the pure output helpers
and factory wire-ups that RunE-level tests would need a live bus to
exercise:
- writeStopJSON: shape assertions + nil → [] (scripts expecting
.results | length must not see null).
- writeStopText: stdout vs stderr routing — stopped / no-bus lines to
stdout, refused / errored lines to stderr.
- busState.String: all three discriminator values.
- humanizeDuration: each bucket boundary (seconds / minutes / hours / days).
- writeStatusText: covers stateNotRunning / stateRunning (with consumer
table) / stateOrphan (with kill hint).
- writeStatusJSON: orphan entry carries suggested_action + issue;
running entry must NOT carry those fields (hint-leak guard for
scripts that key on issue != "").
- exitForOrphan: flag-off never errors; flag-on errors iff any orphan
is present, with ExitValidation code.
- NewCmdConsume / NewCmdStatus / NewCmdStop / NewCmdList / NewCmdBus:
flag registration + RunE presence, so review catches flag-name drift.
NewCmdBus check also pins Hidden=true.
Lifts cmd/event coverage 51.7% → 61.1%; aggregate event-package
coverage crosses the 60% codecov patch threshold (62% locally).

* fix(event): address lint + deadcode CI failures
4 golangci-lint findings + 1 deadcode finding flagged on PR #654.
lint
----
1. cmd/event/stop.go:86 (ineffassign): `targets := []string{}` is
overwritten by both branches of the `if o.all` below, so the empty-
slice initializer is dead. Switched to `var targets []string`.
2. cmd/event/consume.go nilerr: the user-identity scope preflight
swallows a non-nil ResolveToken error and returns nil. This is
intentional — a missing/expired user token must not block consume;
the bus handshake will surface the real auth error with actionable
hints. Added `//nolint:nilerr` with a 4-line comment pinning the
reasoning.
3. events/im/message_receive.go:62 nilerr: malformed JSON payload
returns the original bytes + nil so consumers still see the event
(the WARN breadcrumb lives in the outer loop). Added
`//nolint:nilerr` with a one-line comment.
4. internal/event/schemas/fromtype_test.go:26 unused: `unexportedStr`
is a reflection-test fixture — its presence (not value) exercises
the FromType skip-unexported path verified at the "unexported
field should not be in schema" assertion. Added `//nolint:unused`
and a 4-line comment pointing at the guarded assertion.
deadcode
--------
5. internal/event/testutil/testutil.go: NewTCPFake has no callers in
the repo. Removed the constructor plus the `inner == nil` TCP-mode
branches from Listen / Dial / Cleanup. FakeTransport now only
supports the wrapped-overlay mode (NewWrappedFake), which is the
one every existing test uses. Doc comment simplified accordingly.
Verified locally: go test -race -timeout 120s across ./cmd/event/...,
./events/..., ./internal/event/... all green; gofmt clean; go vet
clean.

* fix(event): drop stale enum + simplify protocol test type helper
- events/im/message_receive.go: dropped the `enum` tag on
ImMessageReceiveOutput.MessageType. convertlib registers many more
message types than the old 11-item list (video / location /
calendar / todo / vote / hongbao / merge_forward / folder / ...),
so a partial enum would tell AI consumers that valid values like
"video" are invalid and produce false-negative JQ filters.
- internal/event/protocol/messages_test.go: collapsed the
typeOf → reflectTypeName → stringType chain in
TestEncode_DecodeRoundtripAllTypes to a single fmt.Sprintf("%T", v).
The hand-maintained type switch silently returned "<unknown>" for
any new message type, which would have let future Decode bugs slip
past the roundtrip assertion. Also removed a dead `cases` table at
the top of TestConstructors_PinTypeField left over from an earlier
refactor.

- cmd/event/schema.go: renamed the writeSchemaJSON hint field

* fix(event): dedup self-eviction race + protocol oversized-frame test
dedup: in IsDuplicate, the ring-slot eviction step deleted seen[id] even
when ring[pos] equalled the freshly-recorded id (post-TTL reinsertion
landing on its own historical slot). Net result: ring still held id but
seen did not, so the next IsDuplicate(id) returned false and the
duplicate was delivered. Skip the delete when old == eventID. New
TestDedupFilter_SelfEvictionPreservesFreshEntry pins the invariant by
pre-loading the ring slot and asserting the second call still reports
duplicate.
protocol: TestReadFrame_RejectsOversized used strings.Contains feeding
t.Logf, so any non-nil error passed — including a future regression
that returned io.ErrUnexpectedEOF while silently keeping the buffer
unbounded. Promoted MaxFrameBytes overflow to a sentinel
ErrFrameTooLarge and the test now asserts via errors.Is.

* fix(event): replace cmdline-regex bus discovery with PID file + close concurrent fork race
Bus discovery previously walked the OS process table and parsed `--profile cli_*` from
cmdline; the regex rejected any non-cli_ profile name (D-03a). Replace with per-AppID
bus.pid + bus.alive.lock under events/<AppID>/, probed via try-lock. AppID round-trips
through the directory name, so the profile-vs-AppID confusion is gone by construction.
Also fix B-07 (two consumers each fork an independent bus, halving event delivery):
- forkBus holds bus.fork.lock until child is dial-able, not just until cmd.Start
- bus daemon takes alive.lock before binding the socket; cleanup-TOCTOU race can no
longer leave two listeners on different inodes
status.go renders an orphan with PID=0 distinctly (live bus but pid file unreadable)
so we never print "Action: kill 0".

- consume: ignore SIGPIPE so a closed stdout pipe (e.g. `... | head -n 1`)
surfaces as EPIPE error and reaches the existing isTerminalSinkError
cleanup path (log "output pipe closed", lastForKey query, hub
unregister), instead of being killed by Go's default fd 1/2 SIGPIPE
handler with exit 141 and zero deferred cleanup.
