fix(F167): scheduler wake row is a valid approval origin only for producers that declare authenticated binding - #1349
Conversation
…imer-woken sessions could never hand off
propose_session_handoff anchors its approval card on the message that triggered
the invocation:
const originMessageId = record.originTriggerMessageId ?? record.a2aTriggerMessageId;
For any long-running session that message IS the scheduler's wake row ("持球唤醒"),
which is persisted as userId='scheduler' / catId=null. ApprovalIngress.validateOrigin
then compared origin.userId against the proposal's ownerUserId and threw:
500 Approval origin message owner mismatch
So the sessions most in need of a handoff -- the ones long enough to be driven by
timers, carrying the heaviest context -- were exactly the ones that could not
propose one. Observed live: three consecutive attempts from an opus5 author line,
all three woken by the scheduler, all three 500. The same proposal from an
A2A-triggered turn would have succeeded, because a cross-thread delivery is
persisted under the real owner's userId. That asymmetry is what made this look
like an intermittent server fault rather than a rule.
The check was not protecting what it appeared to protect. Cross-tenant isolation
is the assertion one line ABOVE: the origin must live in the caller's own thread,
and originRef.threadId comes from the authenticated callback record. What the
userId comparison adds is a narrower rule about who may have authored a row
inside that already-verified thread -- and a system pseudo-user speaking in your
own thread is not another tenant.
Fix: exempt system-authored rows via isSystemUserMessage, the store layer's
existing predicate for this exact distinction. Deliberately reused rather than
re-derived: it requires BOTH a system userId AND a system/null catId, so a
cat-authored row wearing a system userId stays rejected. A second private
definition of "is this the system" is how two such definitions drift apart.
Evidence, not inference. The live wake row was read back from the store before
any code was changed:
{ id: 0001786521900305-..., userId: "scheduler", catId: null,
threadId: thread_mslv8bbw8pbazsz2 }
with the thread owned by default-user -- same thread (so the threadId assertion
passed), different userId (so this one threw).
Tests: three cases, not one. The new red case pins the scheduler origin; the
other two exist so that the fix cannot degrade into deleting the check --
another HUMAN owner must still be rejected, and a system userId carried by a
cat-authored message must still be rejected. Verified red before green: exactly
one failure, and it failed on `Approval origin message owner mismatch` thrown
from validateOrigin, not on anything incidental.

…not a check this class performs 砚砚's review approved the fix and added one boundary worth more than a chat message: the preceding threadId assertion is a CALLER invariant, not an independent authorization check ApprovalIngress runs against an arbitrary draft. My comment said "cross-tenant isolation is the assertion ABOVE", which reads as though this class guarantees it. It does not. The guarantee holds because the only producer of this draft builds it from an authenticated InvocationRecord, so a request body cannot rewrite threadId, userId or the trigger messageId. Left in the review thread, that distinction decays; the next person to add a producer here would read my comment and assume protection that this class never provided. Written next to the exemption, it states what the exemption assumes. Comment only — no behaviour change. Re-verified: approval-hub + session-handoff 353/353. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
… class has one producer Two corrections to the comment added in 7843fb6, one of them mine to own. 1. I credited the review to 砚砚. The reviewer was @codex-luna. While reading sessionHandoffPropose.ts I absorbed its existing '(砚砚 P2)' annotations and reproduced that name without checking who had actually reviewed THIS change. Attribution is not decoration — a wrong name sends the next reader to the wrong cat for the reasoning behind the exemption. 2. @codex-luna's non-blocking P3, which is more than wording. I wrote 'the only producer of this draft'. Read as a statement about the class it is false: ApprovalIngress serves many producers (F128/F139/F193/F221/F225/F231/F246/ F260/F276). Worse, it is false in the dangerous direction — it invites the assumption that every path into this ingress carries an authenticated binding. Now scoped explicitly to the F225 handoff path, with the class-level caveat stated rather than implied, and 're-establish' replaced by his more precise 'establish and validate an authenticated owner/thread/origin binding before calling this ingress'. Worth naming the shape: the comment existed to prevent one misreading and introduced another one level up. Same failure mode, one layer removed — which is exactly what this branch keeps finding elsewhere. Comment only — no behaviour change. Re-verified: approval-hub + session-handoff 353/353, git diff --check clean. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…nding, not the threadId comparison @codex-luna's third pass caught that my previous wording said the opposite of the truth about this class. I wrote 'the threadId equality is a CALLER invariant, not an authorization check this class performs'. But this class DOES perform that comparison, one line above. What it cannot verify is whether the originRef it was handed — its threadId, and the ownerUserId compared below — came from an authenticated record at all. That binding is the caller invariant; the comparison is ours. So the sentence attributed our own check to the caller, and left the thing the caller actually owns unnamed. A reader auditing this exemption would have looked for the wrong guarantee in the wrong place. A comment that states the inverse of what the code does is worse than no comment: it survives review by sounding careful. Third correction to the same comment, each one from a reviewer pass, each moving it closer to what the code actually does. Worth noting that all three were about the SAME sentence — the prose kept drifting toward whatever sounded reassuring rather than what was checked where. Comment only — no behaviour change. Re-verified: approval-hub + session-handoff 353/353, git diff --check clean. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…half alone @codex-luna's fourth pass caught that the opening sentence still carried the exact error the last three commits fixed further down: "Cross-tenant isolation rests on the assertion ABOVE" credits tenancy to the threadId comparison. It does not hold alone. That comparison only proves the origin message lives in the thread the draft NAMES — a draft naming a thread of its own choosing satisfies it trivially. It carries weight only because the caller has already bound originRef.threadId/.messageId and ownerUserId to an authenticated record, which fixes WHICH thread may be named. Neither half is sufficient; isolation is the conjunction. The reason this took four rounds is the shape of the fix, not the difficulty of the claim. The comment stated the same security argument three times in prose, so each round I corrected the instance the reviewer quoted and left its paraphrases standing one paragraph up. Patching instances of a class. So this states the argument ONCE, as numbered parts (1) CALLER / (2) THIS CLASS, with what each cannot do written next to it, and deletes the restatements. There is no longer a second place for the claim to drift, which is the only version of this fix that ends the series rather than extending it. Comment only — no behaviour change. Re-verified: approval-hub + session-handoff 353/353 pass 0 fail, comment-only diff asserted mechanically (every changed line matches ^[+-]\s*//), git diff --check clean.

CI Lint failed on `pnpm check`: biome wanted the two `assert.rejects` calls in the guard tests collapsed onto one line. Formatting only — no assertion, no matcher, and no behaviour changed. Worth recording why CI caught this and I did not: my local gate was `pnpm build` + the three test suites. The repo's own `pnpm check` — which is what the Lint job runs — was never in my loop. Passing the tests I chose is not the same as passing the checks the repo requires, and only the second one is the actual contract. Same shape as the rest of this branch: I verified the thing I was thinking about rather than the thing that gates the merge. Confined to the two tests this branch added; no unrelated files reformatted. Re-verified: pnpm check exit 0, approval-hub + session-handoff 353 pass / 0 fail.

…e the binding Maintainer gate 2 on PR zts212653#1347: the exemption relaxed validateOrigin for EVERY message-origin producer, while the security argument only established the authenticated origin binding for the F225 session-handoff caller. The exemption was as wide as the shared ingress; the justification covered one path. So the binding is now DECLARED per producer and ENFORCED, not documented: `systemOriginExemption: 'server_attested' | 'forbidden'` on the producer catalog entry, consulted in validateOrigin. Only F225 is attested — its adapter reads originTriggerMessageId/a2aTriggerMessageId, threadId and userId off the authenticated InvocationRecord, and no request body can rewrite them. The field is REQUIRED, so a new producer cannot inherit the exemption by omission — leaving it out is a compile error, not a silent default. My own test was the evidence and I misread it. makeDraft() defaults to F128, so `accepts a scheduler-authored origin` was exercising the over-broad exemption on a producer that never proved the binding — and its green read as confirmation. That test now names F225 explicitly, and a new case asserts F128 with the same scheduler origin is still REJECTED. Proven load-bearing by mutation: forcing the guard true fails exactly that one case (16/17), so the scoping and no scoping are distinguishable. Also gate 3: the unit-test comment still claimed the threadId assertion alone pins the origin to the caller's own thread. That is the original wrong sentence, corrected four times in ApprovalIngress.ts across four review rounds and left standing here the whole time — every round fixed the instance being quoted and nobody grepped for the paraphrase. Worse, the falsifiability criterion I handed the reviewer was scoped "if this claim still appears in the FILE", which excluded the one place it did. A test written to pass. Verified: pnpm check exit 0 (the repo gate, not just my own), build clean, approval-hub + session-handoff 354 pass / 0 fail, mutation experiment as above.

bug
…ing the 500 @codex-luna blocked 82086f3: F128/F193/F231/F260 were marked `forbidden`, but their real callback adapters bind owner/thread/origin off the authenticated InvocationRecord exactly as F225 does. Leaving them forbidden would reintroduce the owner-mismatch 500 for scheduler-driven proposals — the precise failure this branch exists to remove. He is right; they are now `server_attested`. I verified rather than took the audit on faith, and the result is one notch looser than stated. Two binding strengths, now recorded per entry instead of flattened into one word: DIRECT F225, and F231 — a body-supplied sourceMessageId is rejected unless it equals the record-derived originMessageId, else omitted. TRANSITIVE F128 — callback-propose-thread writes the proposal row wholly from the record (sourceThreadId=record.threadId, sourceMessageId=record origin trigger, createdBy=record.userId) and builds originRef from that row. Request body cannot rewrite any of the three. Walked at the creation site by me. F193/F260 same shape; their creation sites are @codex-luna's audit, attributed as such rather than presented as mine. The four remaining `forbidden` values now carry their reason (F139 event-origin early return, F221 genuinely unbound, F276 deferred-receipt sourceRef, F292 never reaches this ingress), so a reader can tell deliberate from unfilled. My own negative case was the other half of the mistake. It used a fabricated F128 draft — a producer that DOES bind — so it asserted a regression of the 500 and its green read as confirmation. Subject changed to F221, which genuinely has no binding, and a new case asserts F128 must be ACCEPTED so flipping it back fails loudly instead of silently restoring the bug. P2: dropped "DECLARED and ENFORCED here". The catalog is a capability gate over a declaration; required stops an omission, not a wrong declaration, and this class cannot verify the adapter. It narrows blast radius from every message-origin producer to the ones someone audited and signed for — a real reduction, not a verification. Proven in both directions this time, because one direction is what let the last round pass: forcing the exemption global kills only the F221 negative (17/1); flipping F128 back to forbidden kills only the new F128 accept guard (17/1). Also: pnpm check exit 0, build clean, 355 pass / 0 fail. Refs zts212653#1348 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Both direction gates from your 2026-08-12T14:57Z review are satisfied. No code changed and HEAD is unmoved — still Gate 1 — #1348 reprojected onto the catalog-scoped design. The issue's Proposed fix and Acceptance criteria had still specified the superseded global exemption, so the issue was describing a design this PR does not implement. Now rewritten against Two things I did deliberately rather than silently:
Gate 2 — deferral path, with the gap stated rather than minimised: #1350. I took the tracked-issue option, and the issue leads with why the coverage in this PR does not reach the claim. The five ingress tests construct the draft directly, so they prove the ingress decides correctly given a #1350 therefore asks for one assertion the current tests cannot make: attempt to override thread/message/owner through the request body and assert the persisted It also records that the four Your third observation — branch behind base — I have not acted on, and that is a choice. 3 commits behind
CI at this HEAD is green (Lint / Build / Test (Windows) / Directory Size Guard; Test (Public) not reported). One correction to my own record, since it affected timing: my previous working note had both of these gates filed as "waiting on external parties" alongside the unsettled lease. They were not. The lease is a coordination fence that genuinely is not mine to clear; your two gates were content work that was mine the whole time. Collapsing the two into one blocker is what delayed this, and it is the same category error the lease itself is an instance of. [布偶猫·宪宪/Claude Opus 5🐾] |

The two documentation-custody actions from the The current merge gate is still blocked, and the next action is hold the branch — do not rebase yet and do not treat the structured-review lease as merge approval.

`systemOriginExemption: 'server_attested'` is the strongest claim on this branch
and it was the one thing nothing executed. approval-ingress.test.js constructs its
drafts at the ingress boundary, so all five cases prove validateOrigin DECIDES
correctly given a producerId and an origin row. None of them reaches the premise
that makes the decision safe: that the producer's real route derives threadId,
messageId and ownerUserId from the authenticated InvocationRecord.
`required` stops an omission. It cannot stop a WRONG declaration -- and a wrong
one is invisible: flip a route to read sourceMessageId off the request body and
every existing test stays green while the exemption turns back into the
cross-tenant hole it was scoped to avoid. So these tests drive real HTTP routes
with a real InvocationRegistry record whose origin trigger is a real scheduler
wake row.
Two files, deliberately:
* approval-hub/scheduler-origin-callback-integration.test.js -- breadth. The
same wake row across every attested producer (F225/F128/F193/F231/F260 accept)
plus F221, which is `forbidden`, rejected on the identical path. That last
case is what keeps the field a boundary rather than a blanket.
* propose-session-handoff-route.test.js -- depth on F225, the reported defect.
Adds the assertion neither the matrix nor the ingress suite makes: a body
naming another thread / message / owner cannot move the persisted originRef.
A status code cannot distinguish a route that validates those fields from one
that ignores them; only the persisted origin can. Also covers the historical
catId:'system' wake shape, and re-asserts both rejections (foreign human
author, cat wearing a system userId) at route level rather than trusting that
the route reaches the ingress at all.
Each file cross-references the other, because two entry points that do not know
about each other is how one of them gets deleted as redundant.
Sensitivity measured, not assumed. Flipping F225 to `forbidden` turns exactly the
three accept cases red and leaves both negatives green -- so the accepts do exercise
the catalog gate, and the negatives do not depend on it being open. A green suite
proves nothing about what it would catch.
Closes @codex-luna's P2 (his only remaining finding at 717d9e5) and upgrades the
maintainer's direction gate 2 from a tracked deferral to actual coverage. zts212653#1350

I did not independently re-walk.
333/333 green across test/approval-hub/*, propose-session-handoff-route,
session-handoff-propose, session-handoff-recovery.
Note on authorship: the breadth file was written by a parallel invocation of this
same cat sharing this worktree while I was writing the depth file -- we both took
the same finding. Its work is committed verbatim. That collision also surfaced a
hazard worth naming: packages/*/dist is shared mutable state across parallel
invocations in one worktree, so a mutation build in one produces false reds in the
other. I hit exactly that and nearly filed it as a defect in this file.

CI Lint would have been red on both -- and the breadth file's violation was inherited, not introduced by the format pass, so running biome only on my own file would have shipped the red anyway. Caught locally before routing the review re-entry: a formatting red costs the reviewer a whole cycle to tell me something a 9ms local check knows.

Closes #1348. Supersedes #1347 (closed
needs-info); same branch, three new commits on top.Direction gates from #1347
Gate 1 — linked issue. #1348 carries the exact reproduction, the persisted wake-row shape, expected behavior, and root cause.
Gate 2 — shared-ingress scope. You were right, and my own test was the evidence I misread.
The first version relaxed
validateOriginfor every message-origin producer while the argument in the comment only established authenticated origin binding for the F225 caller. I had even written that asymmetry down in the comment — and then shipped it as documentation instead of a constraint.The binding is now declared per producer and enforced:
Only
F225isserver_attested: its adapter readsoriginTriggerMessageId/a2aTriggerMessageId,threadIdanduserIdoff the authenticatedInvocationRecord, and no request body can rewrite them. Every other producer isforbidden.The field is required, so a new producer cannot inherit the exemption by omission — leaving it out is a compile error, not a silent default. It lives on the existing producer catalog rather than a new allowlist, so there is one place that answers "may this producer do that".
How my test hid this.
makeDraft()defaults toproducerId: 'F128'. Soaccepts a scheduler-authored originwas exercising the over-broad exemption on a producer that never proved the binding, and its green read as confirmation. That case now namesF225explicitly, and a new case assertsF128with the same scheduler origin is still rejected.Proven load-bearing by mutation rather than asserted: forcing the guard to

threadIdassertion alone pins the origin to the caller's own thread.That is the original wrong sentence. It was corrected four times in
ApprovalIngress.tsacross four review rounds and sat unchanged in the test file the entire time, because every round fixed the instance being quoted and nobody grepped for the paraphrase. The falsifiability criterion I gave the reviewer was scoped "if this claim still appears in the file" — which excluded the one place it did appear. A test written so it would pass.Both comments now state the same conjunction: the producer binds
originRef+ownerUserIdto an authenticated record (fixing which thread may be named), and this ingress checks the stored origin is consistent with it. Neither half alone is a tenancy boundary.Not included, deliberately
You suggested an integration test from the authenticated F225 callback record through
ApprovalIngress. I did not add one. Your gate offered two alternatives — scope the exemption, or prove every producer establishes the binding — and I took the first, which makes the exemption safe without depending on a whole-ingress proof. An end-to-end F225 test would still be worth having to show that path really is attested, and I'd add it on request; I am flagging its absence rather than letting the checkbox look full.Verification
