39 hook-ctx call sites across 14 test files still build `ctx.input` inline, so they keep the plain-object blind spot #1295 closed everywhere else

[hotlong]

Filed by the repo:hotcrm PM seat from a measurement reported in PR #1297 (#1295). It is the residual half of that card, deliberately left outside its fence and reported rather than swept in.

The gap

#1295 routed test/helpers/hook-harness.ts's makeCtx through the engine's real wrapper (wrapDeclarativeHook), so a hook handler now receives the flat-record Proxy production hands it instead of a plain object. That closed the blind spot for every call site that goes through makeCtx.

39 call sites across 14 test files do not. They build a hook ctx inline:

const ctx = { event: 'beforeInsert', input, user: undefined, api: harness.api };

so input is a plain object and those assertions keep exactly the under-approximation #1295 removed.

file	sites
test/hooks-runtime.test.ts	18
test/flow-scheduled.test.ts	2
test/forecast-period-boundary.test.ts	2
test/knowledge-deflection.test.ts	2
test/knowledge-feedback.test.ts	2
test/ownership-model.test.ts	2
action-sandbox · demo-staffing · forecast-period-end-boundary · priority-rank-parity · quote-accepted-lookups · quote-accepted-payment-terms · territory-seed-coverage	1 each

(test/case-assignment.test.ts's 4 were converted in PR #1297 — the two the card named plus their handler calls.)

Why it is worth doing rather than noting

This is the shape that produced #1133: fifteen delete statements were silent no-ops in production while the tests asserting them passed, because a plain object honours delete and the engine's Proxy does not. Those tests were not merely failing to catch the defect — they were certifying the opposite of production for as long as it existed.

⚠️ test/hooks-runtime.test.ts alone holds 18 of the 39, and it is a hooks-runtime file — the highest-density place in the repo for exactly the class of defect this shape hides.

The failure also generalises past delete: ownKeys ordering, getOwnPropertyDescriptor, has on an absent key, and the non-enumerable reserved keys all diverge between the two shapes, with the same green tests either way.

Direction

Most of these files carry a single local ctxFor-style builder, so the conversion is roughly one line per file — point the builder at makeCtx (or at the exported engineFlatInput) instead of an object literal.

⛔ Every assertion that changes verdict is a finding to READ, not noise to suppress. #1295 changed no verdict because PR #1294 had already retired the last live delete; these 39 may not be so lucky, and a red here is the instrument finally telling the truth. ⛔ Never weaken, skip or delete a test to get green — if a red is a genuine defect outside this card's scope, stop and report it.

⚠️ Note the one disclosed divergence in the new harness before relying on it: id is hoisted onto the wrapper by copy, so a record carrying id has it in both places and Object.keys lists it where a real per-row update dispatch would not. Approximate in the enumerable direction only — if a converted assertion trips on exactly that, it is the harness, not the hook.

Acceptance

• All 39 sites build their ctx through the shared helper, or each exception is named with a measured reason.
• ⚠️ A pin, or an existing gate extended, that makes a new inline plain-object ctx visible — otherwise the 40th call site re-opens this silently. test/hook-input-shape.test.ts is the natural home.

⚠️ Before anything else: MY OWN CARD'S TABLE IS UNRELIABLE. Re-enumerate.

I filed this card and put a per-file count table in it. Re-measuring on origin/main @ 7250a1f0 at dispatch time, that table does not survive contact:

file	what I claimed	what I measured just now
test/hooks-runtime.test.ts	18	17 event: literals, zero makeCtx — genuinely inline, the real bulk of the card
test/flow-scheduled.test.ts	2	uses a local makeHookCtx builder, not raw literals — different shape from what the card implies
test/ownership-model.test.ts	2	2 multi-line inline literals, no makeCtx — confirmed
test/knowledge-deflection.test.ts	2	3 makeCtx calls; its event: hits sit INSIDE those calls — this file may already be fine

So the "39 across 14 files" figure is a lead, not a measurement. ⛔ Do not work from my table. Produce your own enumeration first and put it in the report — which files genuinely hand a handler a plain object, and how many sites each. If the real number is materially different from 39, say so; that is a finding about the card, not a problem with your run.

⚠️ Note the counting trap I fell into: makeCtx({ event: … }) and handler({ event: … }) both match a naive event: grep, and they are opposites for this card's purpose. Whatever you grep for, state the control that proves it discriminates.

Ruling (⛔ not re-adjudicable)

1. ✅ Route every genuinely-inline hook ctx through the shared helper so it receives the engine's wrapper shape (landed in PR test(harness): hand hooks the engine's input shape, not a plain object #1297).
2. ⛔ Every assertion that changes verdict is a finding to READ, not noise to suppress. The guest-submission harness passes a plain object, so it cannot reproduce the engine's input Proxy — any hook defect living in that difference is invisible while the assertions read green #1295 changed no verdict because PR fix(intake): guest submissions are actually sanitised — overwrite instead of delete #1294 had already retired the last live delete; these may not be so lucky. A red under the real shape is the instrument finally telling the truth. ⛔ Never weaken, skip or delete a test to get green — if a red is a genuine defect outside this card's scope, stop and report it.
3. ✅ Land a guard that makes a NEW inline plain-object ctx visible, or the 40th call site silently re-opens this. test/hook-input-shape.test.ts is the natural home.

PM mechanism assumptions (measured this round — falsify them and say so)

1. makeCtx now wraps via the engine's real wrapDeclarativeHook (PR test(harness): hand hooks the engine's input shape, not a plain object #1297, merged 7250a1f0). Read test/helpers/hook-harness.ts and test/hook-input-shape.test.ts before converting anything — they carry the design and the disclosed divergence.
2. ⚠️ One disclosed divergence matters to you: id is hoisted onto the wrapper by copy, so a record carrying id has it in both places and Object.keys lists it where a real per-row update dispatch would not. If a converted assertion trips on exactly that, it is the harness, not the hook — report it, ⛔ do not "fix" the hook.
3. Files using a local builder (makeHookCtx in flow-scheduled) are a one-line fix at the builder; files with raw literals need per-site conversion. hooks-runtime.test.ts is the bulk and deserves the care.

Non-negotiable

• Gates (read off package.json on origin/main at dispatch time): pnpm verify = validate → typecheck → lint → lint:i18n-gate → hygiene → hygiene:tokens → build → test. Exit codes captured after redirect, never through a pipe.
• ⚠️ Two verify-log lines read like failures and are not: ✗ i18n lint gate: … has no issues array and ✗ source token ratchet failed — both inside the vitest stage, both the gates' own fixture-driven failure paths.
• ⚠️ hygiene now has a size cap on test/ files and hooks-runtime.test.ts is large. ⛔ Do not split a file to get under it and ⛔ do not touch MAX_FILE_BYTES — if your conversion pushes a file over, stop and report; The 100KB hygiene cap has no early warning: silent at 99%, red at 101% — three files have now been found at the moment it bit #1287 is in flight on exactly that advisory.
• Live changeset gate — newly-added .changeset/*.md, or skip-changeset, or empty frontmatter. Test-only is a reasonable candidate for the empty form; say which and why.
• Reverse-verify from a committed state (⚠️ git checkout HEAD -- with the path, never the bare form, which restores from the index; verify the tree afterwards).
• PR draft, base main, first body line Fixes #1298 if you convert them all; Part of #1298 if you deliberately leave some — and name which and why.

My own enumeration: 23 handler dispatches received a plain object, built at 23 literal sites in 6 files, not '39 across 14'. Discrimination control (the trap you named): a naive `event:` grep hits 414 times across 53 files, of which 16 files hold NO hook ctx at all; so both scans key on the CONSUMER (what the object is handed to), parsed with @babel/parser, never on the presence of an `event:` key. Two independent AST scans were cross-checked and agree — one resolving every `*.handler(x)` argument back through identifiers, local builders and import aliases; one over every literal carrying both `event` and `input`, ignoring what it is passed to. Corrections to the card: hooks-runtime.test.ts is 17 not 18 (and is the whole bulk, zero makeCtx before); flow-scheduled.test.ts is 0 — its `makeHookCtx` is `makeCtx as makeHookCtx`, an ALIASED IMPORT, not a local builder; knowledge-deflection.test.ts is 0 (already routed), as you suspected. The card missed its own highest-leverage site entirely: `test/helpers/action-sandbox.ts`'s `runHookBody` built the ctx for 44 call sites across 10 files, all fixed by one line. I verified that site is genuinely in scope rather than assuming it: production reaches the same `boundBodyHandler` through `wrapDeclarativeHook` (bindHooksToEngine -> resolveHandler -> bodyRunner(hook), then wrapped), so a shipped body always sees the Proxy. Four exceptions are named with measured reasons in the PR body (the deliberate pre-#1295 contrast in hook-input-shape; the per-row dispatch Proxy in hooks-runtime-service which models a shape engineFlatInput deliberately does NOT provide; the action ctx and the flow ctx, both different contracts). Guard landed in test/hook-input-shape.test.ts as two rules plus a self-test. ZERO assertions changed verdict — measured reason, not assumed: there is no live `delete` on a hook input left in src/objects/ (the only three matches are comments documenting the no-op, retired by #1294), so the converted assertions are read/assign-only, exactly where the two shapes agree.

It re-enumerated instead of trusting my table, which is what I asked for

I told it my own per-file counts were unreliable. It measured and the numbers land differently again — 23 live sites across 6 files, not "39 across 14". The conversions match what I spot-checked at dispatch: hooks-runtime.test.ts was the bulk (19 sites), ownership-model.test.ts had its multi-line literals, and priority-rank-parity.test.ts's local ctxFor builder is exactly the indirect shape a call-site scan cannot see.

⭐ Two rules, because neither subsumes the other

This is the part that makes it a gate rather than a sweep:

• Rule A reads the CALL — handler({ … }) with an event key. Reports the exact line, which is what makes a violation actionable. Blind to a ctx built one line earlier.
• Rule B reads the FILE — any file calling a hook handler must obtain its ctx from the shared harness. Catches the local-builder forms without tracing them.

Measured against the pre-conversion tree: A caught 22 of 23 sites, B caught all 6 files including the one A structurally cannot see. Two rules with a stated, measured division of labour beats one rule with a blind spot.

The counting trap is handled, and the guard is anti-vacuous

The trap I fell into at dispatch — makeCtx({ event: … }) and handler({ event: … }) both match a naive event: grep and are opposites — is closed by keying on the consumer rather than the presence of an event key. Measured control stated: event: hits 414 times across 53 files, 16 of which hold no hook ctx at all.

Three things make this hold up:

1. A self-test case asserts the guard still matches known-bad planted samples, still recognises the event key, and still exempts a correctly-routed helper. Without it, both rules pass just as happily when the scan is broken and matches nothing — the failure mode a static gate is most prone to, and precisely the one that would let the 40th call site through.
2. codeOnly() blanks comments and string bodies while preserving newlines, so the file's own prose — which spells handler({ … }) several times — does not report itself. A scan that read its own documentation would be permanently red for the wrong reason.
3. An action ctx is skipped rather than mis-flagged, because rule A requires an event key before judging.

⛔ And the guard says in its own text that a violation is not fixed by adding an exception. Right place for that instruction.

The action-sandbox.ts conversion earns its comment

That one is not a mechanical swap and the PR treats it as such: the wrapper is load-bearing on both sides of the sandbox boundary — inbound, unwrapProxyToPlain becomes a real step rather than a no-op; outbound, applyMutationsToInput's Object.assign routes through the set trap into data, which is the caller's record, so the ~44 read-backs are unaffected while a write to a reserved key lands where production puts it. That mechanism is pinned by a new case rather than asserted.

Landing now. Two follow-ups from this round's reports are mine to file: the 64 fixture decoy lines leaking through inherited stderr, and the #1292 findings.
