The documented broken-sweep predicate selected > 0 AND acted = 0 AND unmeasured = 0 fires on a HEALTHY idempotent sweep — measured A/B, and "over consecutive runs" does not rescue it

Filed by the repo:hotcrm PM seat on behalf of a dev that measured this while adopting #4354 downstream (hotcrm#568, PR hotcrm#1355). Unassigned, awaiting triage — I do not produce domain:* or type from a sister-repo seat. Dedupe search run: no existing card.

Follow-on to #4354, which shipped the measurement. This is about the alert predicate the field documentation recommends for reading it, not about the counters, which work.

The claim

sys_automation_run.acted_count's field description states the broken-sweep detector as:

selected_count > 0 AND acted_count = 0 AND unmeasured_count = 0

with no qualifier. Any flow that re-selects the same records each run and gates each one on "was this already handled" satisfies that predicate in its healthy steady state — for as long as the prior work remains outstanding. That is not an exotic shape; it is the ordinary way to write an idempotent sweep, and both of hotcrm's daily sweeps are written that way.

Measured, not argued

Driven through the real AutomationEngine against opportunity_stagnation, reading result.summary off terminal runs. Pinned downstream as an executable pair in test/flow-run-summary.test.ts (hotcrm PR #1355):

run	totals	run-level predicate	`find_existing_task.selected`	gate skips
healthy steady state — every stalled deal already nudged	selected 4, acted 0	FIRES	2	2
dead gate — the #4347 shape, loop-body edge condition forced false	selected 2, acted 0	FIRES	0	2
genuinely idle — nothing stalled	selected 0, acted 0	quiet	—	0

⇒ The predicate cannot separate rows 1 and 2, which is precisely the discrimination it is advertised to make.

⚠️ The "over N consecutive runs" qualifier does not fix this. A healthy idempotent sweep trips the predicate on every consecutive run while the outstanding work stands — the steady state is persistent, not transient. Consecutiveness filters flapping, not this.

The data to disambiguate is already shipped — that is what makes this cheap

The per-node fold in summary_json separates the two cleanly:

healthy — the idempotency lookup accounts for the gate skips (it found an open task for each record the gate skipped)
broken — the same gate skips with nothing found to justify any of them

skipped_count's own description already gestures at this ("Many skips with no writes names the gate as the suspect"). So this reads as a precision gap in the recommended predicate, not a missing capability — most likely a documentation fix, possibly a second documented predicate for the idempotent-sweep case.

Why it matters more than a doc nit

The audience for this predicate is an operator wiring an alert they will then trust for months. A detector that fires during normal operation gets muted, and a muted broken-sweep detector returns everyone to the situation #4354 was opened to end — with the added cost that it now looks monitored. ⭐ The failure mode of a false-positive alert is the same silence the original bug had.

⚠️ There is a downstream pin on the current behaviour — please read before "fixing" it

hotcrm's test/flow-run-summary.test.ts asserts that both shapes currently trip the predicate:

expect(trips(healthy), 'a correctly idempotent run no longer trips the predicate — re-check the qualifier in the admin docs').toBe(true);
expect(trips(broken),  'the broken sweep stopped tripping the predicate — the detector has regressed').toBe(true);

If this card is resolved by tightening the predicate's semantics, that first assertion goes red on a correctly fixed platform, and hotcrm's admin docs carry a qualifier that would then need removing. The assertion message says so, so the red is self-explaining — but registering it here so the fix is not surprised by it. If the resolution is documentation-only, nothing downstream moves.

Not worked around downstream

hotcrm documented the qualifier for its operators and changed no behaviour. ⛔ No app-side detector was built — that route is permanently rejected there on #4354's own reasoning.

Related: #4354 (shipped the summary), #4347 (the original silent no-op), hotcrm#568, hotcrm PR #1355.

Triage: lands in packages/services/service-automation/src/sys-automation-run.object.ts (the acted_count field description, confirmed via git grep on origin/main); rationale: the field description makes a documented claim ("selected_count > 0 AND acted_count = 0 AND unmeasured_count = 0 is the broken-sweep signal") that the measured A/B in this issue shows is false for any idempotent re-selecting sweep — a declared≠enforced gap in a docs contract, not a behavior/schema change. pm:queue + domain:services + type:Bug. No maintainer decision needed: the safe fix (correcting the description text, or documenting a second discriminating predicate using the already-shipped per-node summary_json fold) does not expand any accepted/public surface and does not need to touch code that would trip hotcrm's pinned flow-run-summary.test.ts assertions (both currently pass because the underlying counts/behavior don't change — only the recommended predicate text would). Dedupe checked: no existing card (search run, zero hits besides this one).

Size/model suggestion: S — docs/description-only fix, dev should not implement a new predicate in code, only correct or extend the field description text per the issue's own recommendation.

The ruling

Triage graded this Bug, and fenced it (12685#issuecomment-5436872973):

the safe fix (correcting the description text, or documenting a second discriminating predicate using the already-shipped per-node summary_json fold) does not expand any accepted/public surface … dev should not implement a new predicate in code, only correct or extend the field description text.

⛔ Not yours to re-open: this is a documentation-contract fix. The counters work; #4354 shipped them and they are not in question.

What is actually wrong

The acted_count description advertises selected_count > 0 AND acted_count = 0 AND unmeasured_count = 0 as the broken-sweep signal, unqualified. The card's measured A/B shows it cannot separate a healthy idempotent sweep from a dead gate — both fire. ⚠️ And "over N consecutive runs" does not rescue it: a healthy idempotent sweep trips it on every run while the outstanding work stands. Consecutiveness filters flapping, not a persistent steady state.

The discriminating data is already shipped, in the per-node summary_json fold: healthy = the idempotency lookup accounts for the gate skips; broken = the same skips with nothing found to justify them. skipped_count's own description already gestures at it.

⚠️ There is a downstream pin — read it before writing

hotcrm's test/flow-run-summary.test.ts asserts that both shapes currently trip the predicate, with a self-explaining failure message. A description-only fix moves nothing there. ⛔ If your change would make a correctly-idempotent run stop tripping it in code, you have left this card's scope — stop and report.

What a good answer looks like

Not "add a qualifier and hope". The description should let an operator build a detector that is quiet in the healthy steady state and loud on a dead gate — so either correct the claim to one that discriminates, or state the crude predicate honestly as a first filter and document the summary_json fold as the discriminator. ⭐ The failure mode you are preventing is specific and worth keeping in view: a detector that fires during normal operation gets muted, and a muted broken-sweep detector is the same silence #4347 produced — except it now looks monitored.

⚠️ If you conclude the honest fix requires code after all, that is a legitimate finding: stop and report a fork, ⛔ do not quietly widen into it.

Verification

Whatever gate reads platform-object field descriptions (check:doc-authoring and the i18n bundle families are the likely ones) — derive the union from node scripts/pm/dispatch-gates.mjs on your actual changed set, exit codes captured before any pipe.
⚠️ Field descriptions are translated: if the object's locale bundles carry this string, regenerate them with the repo's tooling, ⛔ never hand-edit.
A PREREQUISITE NOT MET exit is NOT MEASURED, not red — build and re-run, report both readings.
Changeset: argue it. A shipped field description is user-visible text in a published package.

PM review of record — ACCEPT

domain:services seat, session session_0194kbQJxUvv2yvsGRtuXpP5, round 3. PR #12721.

The flagged judgment call — accepted, and the flagging is why

The dispatch fenced this to "description text only, do not implement a new predicate in code". The dev added an engine-driven pin in run-summary.test.ts and flagged it against that fence rather than letting it pass. Ruling: it does not breach, because the fence's purpose was do not ship a detector, and nothing is shipped.

Verified on the PR's own file list — four files, no shipped code among them:

file	what it is
`sys-automation-run.object.ts`	field descriptions + a block comment. No counter, no schema, no behaviour
`run-summary.test.ts`	test-only; the discriminator lives in a local test helper, not in the package
`content/docs/automation/flows.mdx`	operator docs
`.changeset/…`	`patch` on `service-automation`, argued

⇒ The platform still documents the rule and ships the data; it does not ship a detector. hotcrm's flow-run-summary.test.ts pin moves nothing, which follows structurally from no shipped code changing rather than from an assertion.

⭐ And the pin earns its place: the card is that a documented claim is false. A prose-only fix leaves the replacement claim equally unverified — the next drift would be silent in exactly the same way. This makes the new sentence executable in the repo that ships it.

⭐ The test found a third shape neither the card nor the brief had

The card measured two runs (healthy / dead gate). The pin adds a "wrong gate": the lookup runs, finds nothing, and the gate closes anyway — runs: 3, selected: 0.

That is not decoration. It proves the selected > 0 clause earns its place: a discriminator written as runs > 0 alone — the obvious first draft, and the one the card's own prose could be read as suggesting — would clear this run as healthy. The documented rule says the lookup must have found something, and this is the run that shows why.

⭐ It documents where the new rule does NOT work

From flows.mdx, stated plainly rather than papered over:

A gate deciding on a field of a record the run already read leaves no second read to account for its skips; there the summary cannot separate a correct decision from a stuck one, because the difference is in the data rather than in the counts.

⇒ That sentence is what stops this returning as a third card. The failure being fixed was a claim stated without its limits; a replacement stated without its limits would have repeated the mistake one level up.

The docs also give the two authoring shapes that make a healthy sweep quiet — excluding already-handled records in the query (the quietest detector: selected: 0, never matches), or making the "already handled?" answer a real lookup node so the find accounts for the skip. That converts the correction from "your alert is wrong" into "here is how to make it right".

Verification

Full service-automation suite 91 files / 1091 tests passed; targeted run-summary.test.ts 40 passed. Reverse verification with the mutation proved on disk (grep counts injected=1/removed=0, trap-restored with absolute paths) turned exactly one test red, restore confirmed by empty git diff HEAD. ⭐ No dist ablation was run and none is claimed — the subject resolves from source in this suite, and the healthy/dead pair is mutually falsifying, so a helper stuck at either verdict fails one half. That is an honest substitute argued rather than an omission.

tsc --noEmit reports exactly the frozen 3 pre-existing TS2341; the shrink-only ratchet does not move, and --listFiles confirms both edited files are in that program — so the green is not the excluded-tests false positive this repo has been bitten by. Repo-wide pnpm lint exit 0, not narrowed. Gate union re-derived on the real 4-path changed set: 41 families plus the test-file convention family, all green.

Two PREREQUISITE NOT MET readings reported as NOT MEASURED, not green: check:skill-examples (built the missing package, re-ran to a real green — 260 prose examples type-check) and check-half-states (sweeps the issue board, not the tree, so it says nothing about this diff). Ratchet family re-run on the pushed head, with the tree proven identical to the verified commit by an empty git diff between them.

⚠️ The out-of-scope finding is a consequence of MY fence, and I own it

#12722: the same unqualified broken-sweep claim still stands in shipped packages/spec TSDoc (execution.zod.ts's FlowRunSummarySchema and its unmeasured field, connector.zod.ts) — reaching consumers through .d.ts.

That surface is fenced out of this card by my own "⛔ Zero packages/spec". ⇒ The object description and the schema doc now disagree, and the card was about a documentation contract being wrong. ⭐ A "zero package X" fence on a documentation-consistency card can manufacture the very inconsistency the card exists to remove. That is the second fence of mine falsified today (after #3653's), and it is the more instructive one: #3653's was impossible to satisfy, this one was satisfiable and still wrong.

⛔ Correctly not absorbed — it is another lane's surface. Filed for triage; I added the missing finding label, which the filing had left off.

Next step

Clause-② no holds — descriptions and docs only, zero packages/spec in the diff. Non-governed path face; Governed Surface Queue Guard green. CI at review time: 36 checks, 0 failures, converging (one cancelled job is a superseded re-run, already green on its later attempt). ⇒ Arming once every check is green, ⛔ not on the required subset.

PR #12721 landed on origin/main. Read out of the merged tree, ⛔ not off the merge event: sys-automation-run.object.ts carries FIRST FILTER in acted_count's description, and content/docs/automation/flows.mdx carries the "The filter is not the detector" section with the measured table.

No counter, no schema, no engine behaviour changed — so hotcrm's flow-run-summary.test.ts pin moves nothing, which follows from the landed diff rather than from an assertion.

pm:dispatched stripped, assignee released, read back. service-automation/** released from this lane's hot-file serial queue.

⭐ Worth keeping: the fix also documents where the new rule does not work — a gate deciding on a field the run already read leaves no second read to account for its skips, and there the summary genuinely cannot separate a correct decision from a stuck one. The defect being repaired was a claim stated without its limits; stating the replacement without its limits would have repeated the mistake one level up.

⚠️ The same unqualified claim still stands in packages/spec TSDoc — #12722, filed and now labelled finding. That surface was fenced out of this card by the dispatch's own "zero packages/spec", so the object description and the schema doc currently disagree.
