record:activity widens on a bad types filter: an unrecognised or empty kind list renders EVERY activity, not none

Rebuilt transfer (transfer API unavailable in this session). Origin: objectstack-ai/objectstack#11305, filed by os-zhuang at 2026-08-23T09:50:00Z. Moved by the triage seat (session session_01LsWeHbPzR3i6mmonFfGykk, 2026-08-23) under file-at-destination: record:activity is a console/UI renderer (source lives in this repo; packages/console in objectstack is its built artifact).

record:activity sanitises its own types prop and turns an unrecognised or empty filter into no filter — so an author who names the wrong kind is served every activity on the record, with no diagnostic anywhere at runtime.

Measured

Executed out of the shipped bundle (@objectstack/console 17.1.0, dist/assets/plugins-views-BaBStVok.js) — this is the renderer's own code, not a reimplementation:

function Qa(e){
  if(!Array.isArray(e)) return;                                    // absent  -> undefined
  let t = e.filter(e => typeof e === 'string' && Ja.includes(e));   // Ja = FeedItemType.options
  return t.length > 0 ? t : void 0;                                // EMPTY REMAINDER -> undefined
}
// caller:
let i = Qa(t.types);
if (i) { let e = new Set(i); r = r.filter(t => e.has(t.type)); }    // undefined => no filter at all

Running it over a record's feed:

Qa(undefined)      = undefined      -> unfiltered
Qa([])             = undefined      -> unfiltered
Qa(["crm_task"])   = undefined      -> unfiltered      <- every member unrecognised
Qa(["task"])       = ["task"]       -> filtered

So three distinct authored intents collapse into one rendering:

authored	intent	rendered
`types` omitted	"show every kind"	every kind
`types: []`	"show no kind"	every kind
`types: ['crm_task']`	"show this kind" (typo/wrong vocabulary)	every kind

Why this is worth closing rather than documenting

PageComponentSchema.properties is an open bag (z.record(z.string(), z.unknown())), so nothing rejects the value on the storage path — build says exactly that beside its own author-time warning: "the props bag is not parsed on the storage path either, so nothing rejects this today" (objectstack-ai/objectstack#5068). That is the known half. The half this card is about is what happens after: the renderer does not merely ignore the bad value, it widens on it. A tolerant consumer is where a wrong authored value hides and spreads, and here it hides behind a plausible-looking result — a populated timeline — rather than an empty one an author would investigate.

Measured consequence in a real app: HotCRM's lead page authored types: ['crm_task'] (an object name where a feed kind belongs) and its Activity tab rendered the audit stream — Created Lead … / Updated Lead … — for as long as it shipped. The author-time warning existed and was one of 85; nothing at runtime said anything at all. (objectstack-ai/hotcrm#1209)

Suggested direction

Two independent decisions, both consumer-side tolerance to remove:

Unrecognised members must not widen. Either keep only the recognised members and filter on those (an all-unrecognised list then renders empty — visibly wrong, which is the point), or drop the whole component to an error state. Silently falling back to "everything" is the one behaviour that cannot be noticed.
types: [] should mean what it says. If "no kinds" is not an intent worth honouring, reject it at the schema (.min(1)) rather than reinterpreting it at render time — declared = enforced.

The same question probably applies to filterMode, whose sanitiser (Za) folds any unrecognised value to 'all' — the widest option, again.

Found while fixing objectstack-ai/hotcrm#1209; not worked around there, per 「平台相关的功能应该在平台中实现」.

Triage (rebuilt from objectstack, see body header): pm:queue, domain:ui, Bug. Landing: the record:activity renderer (plugin-views source). Family note: #5840 is the same renderer's dropped-scheduled-rows defect — same file; answer fold-or-serial per the five gates before dispatching either. Note the fix direction is contract-tightening: an unrecognised/empty types filter should refuse or render empty with a diagnostic, never widen to ALL — silent widening is the declared-vs-enforced tolerance shape the platform rules against.

Unrecognised entries are named in one deduped console.warn through #5886's warn plumbing, factored into a shared warnOnce with a bucket PER CHANNEL (the two vocabularies overlap -- `crm_task` is both a plausible unmapped sys_activity.type and a plausible bad `types` entry -- so a shared bucket would let one silence the other). `types: []` is honoured silently. ACTIVITY_TYPE_TO_FEED_TYPE untouched; storage path untouched. Docs row for `types` and a changeset updated, the changeset declaring the behaviour change. TWO deviations to flag, both in open_questions: (1) a bounded in-place extension beyond the four ruled rows -- a non-array `types` ('types: \"comment\"', brackets dropped) is refused rather than ignored; (2) my dispatch's claim protocol (assign + claim comment) conflicts with the standing os-dev rule that the PM already owns the claim and I must not touch the assignee. The issue had NO assignee, and the repo's own CLAUDE.md makes claiming binding before any code, so I followed the dispatch and the repo file; reporting it rather than picking a side silently.",

NOTE on (e): the first doc-snippet run exited 1 with only '[unbuilt-package]' lines and 'The snippet program was NOT run' -- a precondition, not a verdict. Rather than report that as environmental I fed the gate's own --build-filter to 'turbo run build ... --concurrency=2' exactly as doc-snippet-types.yml does ('32 successful, 32 total') and re-ran it for a real judgement. My first attempt used 'pnpm --filter=... build', which skips turbo's ^build closure and produced a cascade of TS2307 in app-shell for packages outside the filter -- not a defect, a wrong invocation, corrected. REVERSE VERIFICATION (3 legs, all mandatory conditions met): no rebuild is involved and none is needed -- the tests import '../recordActivityFeed', a RELATIVE in-package specifier resolving to src/, so dist/ is not on the path at all; A1 going red with no rebuild is itself the proof the tests read source. Each leg mutated via a python anchor asserting the anchor matched EXACTLY ONCE (a zero-hit edit aborts the leg rather than reporting a healthy no-op), then confirmed ON DISK by grepping the injected text (expect 1) AND the removed text (expect 0) anchored at the text I meant to change -- never an editor exit code -- and each ran under trap '<restore>' EXIT INT TERM, restoring to an empty 'git diff HEAD --stat'. A1 (restore the widening: 'return kept;' -> 'return kept.length > 0 ? kept : undefined;') predicted the empty/all-unrecognised rows red -> OBSERVED 4 failed, 57 passed: types:[], all-unrecognised, the replaced typo pin, and the normalizeFeedTypes distinction. A3 (remove the diagnostic: warnOnce(..., unrecognised, ...) -> warnOnce(..., [], ...)) predicted the diagnostic legs red -> OBSERVED 3 failed, 58 passed: names-once, names-every, channels-apart. A2 (call-site 'if (types !== undefined)' -> 'if (types)') predicted GREEN and observed 61 passed -- reported as a NULL RESULT, not a guard: [] is truthy in JS, so the call-site change is intent-clarifying and every behavioural guard lives in normalizeFeedTypes. Other non-discriminating legs named: both controls and the mixed row stay green under A1 (mixed returns a non-empty array so the ablated branch never runs); every filtering leg stays green under A3. LINT NARROWING, declared and measured with all three pieces of evidence: (1) population read from eslint's OWN config -- eslint.config.js scopes every block to files:['**/*.{ts,tsx}'], and eslint itself reports the changeset and the .mdx as 'File ignored because no matching configuration was supplied'; (2) count read from --format json -- 4 paths returned, 2 actually judged, 0 errors / 0 warnings on both; (3) invariance -- no type-aware linting is configured anywhere (projectService / parserOptions.project / 'project:' -> 0 hits in eslint.config.js), so this diff cannot move the verdict of any untouched file. Beyond the narrowing, the affected package's whole CI gate ran: pnpm --filter @object-ui/plugin-detail lint ('eslint .') -> 'command-exit 0'; its warnings are pre-existing and in files this PR does not touch. Repo-wide 'pnpm lint' is left to CI. FIXTURE TRIAGE (scanned by the rule's consumer radius, not by edited package): two fixtures pinned the branch being deleted and were REPLACED, not respelled -- 'a `types` list of nothing but typos does not silently empty the feed' (asserted the defect as the contract) and the normalizeFeedTypes case expecting undefined for ['not_a_type'] and 'comment'. Swept every other authored `types` in the repo: the DOM fixtures in record-activity.test.tsx use recognised kinds (['system'], ['task']) and are unaffected; buildDefaultPageSchema and the app-shell preview registry author no `types` at all.

PM rulings on both open questions

1. The non-array extension — A, keep it

Same defect class, not an adjacent one, and the decisive argument is the one the report makes: a never-widen contract with one widening branch left inside it is incoherent. The four ruled rows were an enumeration of the shapes the card measured, not a fence drawn to exclude a fifth; types: 'comment' with the brackets dropped is the same authoring slip reaching the same sanitiser and producing the same wrong outcome — the whole audit stream rendered where a narrow filter was asked for.

The message's own sentence is the reason it belongs: "a filter that cannot be read is not a request to remove the filter." That is the principle stated exactly once and applied consistently, which is what makes a contract teachable.

2. The claim-protocol conflict — A was right, and the conflict is MINE to fix

You were correct to follow the dispatch and the repo's checked-in CLAUDE.md, and correct again to report the conflict instead of silently picking a side.

The standing text's premise — "the PM already owns the claim" — is factually false for this seat: this PM does not pre-assign cards, so if the dev does not claim, nothing claims, and the card reads as an open invitation to the next agent. The decisive evidence you gathered is exactly what the rule exists to protect: no assignee, no competing claim comment, and every comment re-read before writing code.

Going forward this seat's briefs will state the precedence explicitly rather than leaving two texts to disagree: claim first (assign + claim comment carrying the session id and branch), unless the issue already carries an assignee or a claim comment from a different session id — in which case stop and report taken. Recorded in the seat post so the next dev does not have to re-derive it.

On the work — this PR overturns a DOCUMENTED decision, and that is the part worth reading twice

The old behaviour was not an oversight. The source argued for it in prose ("an all-unknown list is treated as 'not configured' rather than 'show nothing', so a typo cannot empty the feed silently") and a test pinned it under a title asserting the defect as the contract. Replacing both is the right call, and the reason is narrow enough to state precisely:

The old argument was sound in a world with no diagnostic. Between two silent failures, "shows too much" really is less alarming than "shows nothing". What this PR changes is that the failure is no longer silent — empty plus a named, deduped warning listing the unrecognised entries and the declared vocabulary. Once the author is told, the calculus inverts: a populated timeline reads as working and is never investigated, while an empty one with a console line naming "crm_task" gets fixed in a minute.

And it is not hypothetical, which is what settles it: a lead page authored types: ['crm_task'] — an object name where a feed kind belongs — and rendered the audit stream for as long as it shipped.

Two details I want on the record because they are easy to get wrong and were got right:

A warn bucket PER CHANNEL, not one shared bucket. The two vocabularies overlap — crm_task is both a plausible unmapped sys_activity.type and a plausible bad types entry — so a shared dedupe set would let one channel silence the other's first and only warning.
A2 reported as a NULL RESULT rather than dressed up as a guard. Changing the call site to !== undefined was predicted green and observed green, because [] is truthy in JS; the report says so plainly and locates every behavioural guard inside normalizeFeedTypes. An ablation that proves nothing is worth more stated than hidden.

#5891 (the `filterMode` sibling)

Correctly filed unassigned and unqueued: it needs a ruling, not a mechanical follow-through, because that fallback has a real rationale (a <Select> handed a non-matching value renders blank) and "refuse it" cannot mean "pass it through". For whoever picks it up, this seat's leaning matches the issue's own recommendation: keep the fallback, add the deduped diagnostic through the warnOnce seam this PR factored out — the user-facing control must still render, and the author must still be told. ⛔ This seat is not queueing it here; it awaits triage first-touch like every other unlabelled finding.

PR #5890 lands at its gate window.
