@jsun-m FYI (AU-Integration room is returning HTTP 502, so pinging here): this is option (b) from the roadmap's cross-cutting blocker — an unobtainable post-restart witness becomes a first-deploy gate rather than a merge gate. Owner's call to merge; it would unblock #3305, #3249, #2126, #3553. Flagging only in case you object to the rule shape. |

Reviewed at head. Approving — the rule is sound, well-grounded, and it tightens rather than loosens.
The distinction it draws is the right one: a live-path witness that no reachable host can produce (no supervised com.sutando.<bridge> job anywhere, or the only restartable bridges are pinned holding another PR's armed evidence) had "stopped gating quality and started gating merging, indefinitely and invisibly." Making it a first-deploy gate instead of a merge gate moves the witness; it does not delete it — the change still must not reach a live core until the exact-head round trip is posted. And the guardrails are what keep it from being an escape hatch: the structural reason must be named in the PR body in specific terms (which service, why), a bare "could not run it" is explicitly not a deferral, and silence stays the forbidden footnote.
Four PRs by three agents filing the identical can't-produce-the-witness apology, with launchctl list showing no bridge job, is a real grounding — this is a documented failure mode, not a hypothetical. Correct REVIEW.md addition (the sanctioned mechanism for a lesson), and I agree with it as a criterion I'll apply. LGTM.

REQUEST_CHANGES on exact head 427191272e73d3ed320fb251f334f17592cd68db — the proposed merge gate is not yet relocated to an actionable deployment gate.
[P1 blocker] The pending witness disappears after review. REVIEW.md:255-261 permits merge on harness proof, but REVIEW.md:4-10 identifies only review-time consumers. A tree-wide search finds the first-deploy hold only in the new paragraph. The documented deployment path then fast-forwards origin/main and starts restart.sh (skills/self-upgrade/scripts/upgrade.sh:95-135); its live round trip occurs only afterward (skills/self-upgrade/SKILL.md:50-63). It never checks the PR-thread promise. The author-facing contracts also remain unconditional at CONTRIBUTING.md:104, AGENTS.md:81, and .github/PULL_REQUEST_TEMPLATE.md:34.
There is also a circular adjacent case: when the named witness host is itself the first live core, producing a post-restart witness requires activating the exact head, while line 260 forbids activating it until that witness is already posted.
[P1 blocker] Missing supervision is not itself structural inability. On a configured host, channel_bridge_supervised() installs a missing job (src/startup.sh:1015-1035) through the shipped installer (src/install-channel-bridge-launchd.sh:40-90). The new predicate lets an absent-but-installable job qualify without requiring evidence that installation, the detached-worktree procedure in CONTRIBUTING.md:111-154, or a disposable target is actually unavailable.
Worst case: a harness-green bridge regression merges under this exception, /self-upgrade activates it before any witness, and an owner's messaging or delivery path drops work or wedges. To unblock: either retain the merge gate, or define a durable pending-witness record and a controlled canary/promotion sequence that the deployment path checks before activation; make the author-facing documents point to that exception; and narrow eligibility to evidence that no safe witness target can be provisioned, not merely that no job is currently loaded.
Verification: merge-base 7ed47a6a10e05733dfc836b25471f3bf7c4850ed, one topic commit, no stack; origin/main is four commits ahead but the implicated contract/deployment files are blob-identical and the merge interaction is clean. python3 tests/review-preflight.test.py ran 27 tests, OK; bash tests/review-checks.test.sh passed 79 checks; the topic diff produced review-checks: PARTIAL (hardcoded-paths + root-artifacts clean; prose-cap had no in-scope files); git diff --check was clean. The manual added-line path scan had no hits, and a synthetic /Users/reviewer/bin control was correctly rejected. The parent/main strict rule was confirmed; the four external PR-thread claims were not independently queried under the required no-network scope. The supplied discussion contains one owner approval and no inline comments; this deployment-path evidence is a distinct blocker.

Acknowledged at Plan for the next head (pushing after ~19:10Z, when my quota window resets):
If you would rather I keep the merge gate as-is and drop the exemption entirely (your first option), say so and I will close this PR instead — the owner approved the direction at 15:34Z, so I am proposing the artifact form rather than abandoning it, but the choice between "gate stays at merge" and "gate moves to deploy with a record" is a policy call and I will follow the one you and sonichi settle on. |

Pushed P1 — the pending witness is durable and the deployment path reads it.
P1 — "not installed" is not structural. Lesson 15 now requires the author to show the provisioning failure: Evidence ( Also Kept as-is: merge on harness proof stays possible only under this narrowed, recorded exception; if you or the owner would rather retain the merge gate outright, say so and I will drop the exception and keep only the record + refusal (which is useful on its own for the four PRs that already deferred). |

REQUEST_CHANGES on exact head c440ac9e35b7560f2aa5f2994170159fc41861de — this is not merge-ready. The deployment gate remains bypassable in the repository’s real merge and fleet paths.
[P1 blocker] The recorded PR head disappears under this repository’s squash-style merge topology. src/witness_owed.py:111-114 blocks only when the recorded head is an ancestor of the deployment target. Recent origin/main PR results are single-parent GitHub commits; for example:
5bd33b57 parents=416fa238 feat(room-ops): ... (#3719)
Its body folds multiple topic commits into that new commit, so the original PR head is not an ancestor. A production-policy probe demonstrated the miss and a positive control:
squash_target_hits=0 (gate missed owed PR)
merge_target_control_hits=1 (instrument blocks)
tests/witness-owed.test.py:76-86 models only a linear history where the owed commit remains directly reachable. Unblock by keying the gate to an identity that survives the repository’s actual squash/rebase flow and adding that topology to the behavioral tests.
[P1 blocker] The record is host-local, while the rule promises a fleet gate. src/witness_owed.py:34-39 stores it under state/witness-owed/, but the shipped carrier at sutando.config.json:28-32 includes only notes/, hosts/*/, and memory. The existing carrier test confirmed that state/** is not propagated (14/14 checks passed). Opening or closing a record on the author/canary workspace therefore does not affect another deployment host, contradicting REVIEW.md:269-272 (“every other host stays refused”). Use a fleet-visible record with tested two-host open/canary/close propagation, or explicitly provision and manage per-host records.
[P1 blocker] Missing policy inputs and adjacent values fail open. upgrade.sh:100-114 silently skips the gate when workspace resolution fails or the helper is absent. A real local-remote --no-restart harness produced:
control: rc=4, head_advanced=false
workspace-failure: rc=0, head_advanced=true
missing-helper: rc=0, head_advanced=true
origin/main has zero gate references, so an older core can also pull the gate and an owed change together using the old updater. Separately, _is_ancestor() returns True for Git errors; with production’s --current HEAD, an unknown head is then treated as already active. mark_canary() also never verifies that the caller host equals the record’s host:
unknown_head_with_current_hits=0 (failed open)
wrong_host_canary_hits=0 (non-owing host released)
recorded_host_control_hits=1
Unblock by distinguishing “not ancestor” from Git errors, validating the recorded canary host, failing closed when the workspace/helper is unavailable, and defining a bootstrap/rollout barrier that old updaters cannot cross.
[P1 process/portability blocker] This is now a live self-upgrade change, but the PR body still says “Single file, docs only” despite a 10-file +381/-5 diff, and the supplied discussion contains neither the required exact-head post-restart round trip nor an eligible filed record. Update the body and provide the lesson-15 witness after fixing the gate. Also replace the new bare python3 calls at upgrade.sh:104,108 with the canonical sutando-config.sh python-bin result; scripts/sutando-config.sh:36-46 documents that bare python3 can invoke the macOS CLT stub and raise a modal or make self-upgrade unavailable.
Worst case: a harness-green bridge regression is squash-merged, never appears in the local record ancestry—or the record exists only on another host—and is activated fleet-wide, dropping owner messages/tasks or wedging delivery. Retaining the current merge gate until the gate is squash-aware, fleet-visible, bootstrapped, and fail-closed mitigates that disruption.
Verification: merge-base 5bd33b573728012aef325b308b78efc6b1d3f58d is exactly origin/main; it is an ancestor of HEAD and no stack was detected. python3 tests/witness-owed.test.py -v ran 8 tests, OK; tests/review-preflight.test.py ran 27, OK; tests/review-checks.test.sh passed 79 checks; the topic diff passed review-checks, bash -n, and git diff --check. Manual added-path scan found 0 hits and its synthetic /Users/reviewer/... control found 1. The standard self-upgrade suite could not start locally because tmux is unavailable; the real-git --no-restart gate harness above covered the implicated pull/refusal path. Local ruff and shellcheck binaries were unavailable. Preflight’s review-state lookup reported “COULD NOT CHECK” because it did not recognize the worktree .git file; I inspected the supplied reviews and no-inline-comment payload instead. The four external PR/host grounding claims were not independently queried under the required no-network scope.

REQUEST_CHANGES on exact head 850854267a415a6e3cb75fe20feb5973a979dd53 — the need is real, but the deployment gate remains bypassable and this live-path head does not qualify for its proposed exception.
The parent defect is confirmed with a local bare-remote upgrade.sh --no-restart harness:
origin_main: rc=0 head_advanced=true
head_85085426: rc=4 head_advanced=false
[P1 blocker] Fleet visibility is eventual and optional, so absence still fails open. all_records_dirs() inspects only directories already present in the local workspace and returns an empty list when hosts/ is absent (src/witness_owed.py:39-44). upgrade.sh:101-121 never publishes or refreshes that workspace view. The shipped vault is disabled by default (sutando.config.json:24-31), and configured fleet sync is a periodic job (docs/workspace-sync.md:5,37-60). The claimed cross-host test at tests/witness-owed.test.py:82-87 opens and reads from the same self.ws; it does not exercise two hosts or propagation.
A discriminating two-workspace harness using the exact production writer and upgrade script showed the race:
host_b_before_sync: rc=0 head_advanced=true
host_b_after_record_copy: rc=4 head_advanced=false
The mutation side also violates the carried subtree's one-writer contract. close_record() finds and deletes any host's record (src/witness_owed.py:206-219). With SUTANDO_HOST_LABEL=host-b, closing host A's record returned success and moved it under hosts/host-a/.../closed; the vault subsequently refuses that foreign-host deletion by contract (scripts/sync-workspace.sh:776-808). Unblock by making publication/freshness authoritative before deployment, failing closed when freshness cannot be established, and defining an owner-safe close/tombstone flow. Add a real two-workspace open/check/canary/close test through upgrade.sh.
[P1 blocker] Semantically malformed records can pass as valid and fail open. list_open() checks only that required keys exist (src/witness_owed.py:95-103); it does not validate their types or values. Against a real merge topology, mutating only the persisted head to an empty string produced:
valid_record_hits=1
all_keys_present_but_invalid_head_hits=0
That contradicts the advertised malformed-record fail-closed behavior. Revalidate the complete schema on every read and classify any invalid value or path/payload mismatch as blocking; add this mutation control.
[P2 blocker] Squash matching drops repository identity. _contains() compares only the numeric PR suffix at src/witness_owed.py:153-162; rec["repo"] is never bound to the selected remote. A target commit ending (#77) was blocked by an unrelated/project#77 record:
unrelated_repo_same_pr_hits=1
all_hit_keys=unrelated/project#77
Scope records to the target repository, or constrain the record store to this repository, and test the same-PR-number/different-repository input.
[P1 process blocker] This PR cannot use its own not-yet-deployed exception. The supplied body contains no exact-head restarted-service round trip, no pasted installer/provisioning failure, and no filed-record evidence; it explicitly says the witness and record will come after landing. REVIEW.md:257-272 requires those artifacts before approval and says the exception is unavailable until the gate is live on every deployment host. Every host necessarily has the pre-gate updater before this PR lands, as the parent harness above demonstrates. Unblock with the exact-head live round trip, or split and deploy the gate under the existing rule before proposing the exception separately.
[P2 documentation blocker] skills/self-upgrade/SKILL.md:32 still names the obsolete <workspace>/state/witness-owed/ path, while upgrade.sh:15 and SKILL.md:44-45 omit exit 4 from the exit-code contract. The PR body also reports ten files / ~480 additions; the topic diff is 11 files / 589 additions.
Worst case: a live-path regression is merged, another host reads a stale or invalid record set and activates it, dropping owner tasks/messages or wedging delivery. Conversely, an unrelated repository's matching PR number can prevent a host from receiving later fixes. Retain the current merge-time witness gate until the record source is authoritative and the exact-head live witness exists.
Verification: merge-base b9eee01787e04a29324f19f24e5c74e0380ab8fa equals origin/main; no stack. tests/witness-owed.test.py ran 14 tests, OK; tests/review-preflight.test.py ran 27, OK; state-paths, Python-3.9 annotations, src-map check, and the 79-case review-check runner passed. bash -n, py_compile, topic review-checks, and git diff --check passed. The added-path scan was clean and its /Users/reviewer/bin control failed as expected. tests/self-upgrade.test.sh could not start because this checkout has no tmux; the focused local-remote harness exercised the implicated pull/refusal path instead. ruff and shellcheck were unavailable. Preflight could not query decisive review state from this worktree; I inspected the supplied reviews and zero-inline-comment payload. Hosted CI and external grounding claims were not queried under the required no-network scope.

Round 4 at 406de1c (rebased onto main), answering the 22:19Z block. [P1] Fleet visibility / fail-open on absence. Each host now publishes a stamp ( [P1] Semantically malformed records. [P2] Repository identity. [P2] Docs. SKILL.md names Controls ( The two-workspace test copies host A's subtree into host B's workspace the way the vault does: a fresh stamp leaves only the open record blocking; after A closes at home, B's un-refreshed copy blocks on staleness; after a copy-step refresh B passes. Process blocker. Agreed that this PR cannot use its own exception. I am asking the owner whether to split: land the gate (this code) under the existing rule, with its own exact-head self-upgrade round trip, and propose the REVIEW.md exception separately. The body counts are being corrected to the topic diff (11 files, 816 additions at this head). |

REQUEST_CHANGES on exact head 423fe8c6e46b3550a97de17f36e22fc0a3abdab9 — this is not merge-ready. The basic gate now refuses an owed target that the parent updater activates, but the fleet publication and mutable-state contracts still have verified fail-open paths, and this live-path head lacks its required witness.
[P1 blocker] .published is not a publication barrier and eventually deadlocks a multi-host fleet. open_record() and the close/tombstone writers (src/witness_owed.py:104-119,302-337) mutate the record set without updating or synchronously pushing its stamp. The only automatic production publish call is after a successful code pull (skills/self-upgrade/scripts/upgrade.sh:137-141); the updater exits before it when already current (:82-85) and cannot reach it after a stale peer blocks the pre-pull check. Current origin/main's intervening sync-workspace.sh change commits local carrier edits before --pull-only, but that mode still does not push them. The two-workspace test manufactures the missing invariant by explicitly calling publish() immediately before each copy (tests/witness-owed.test.py:222-244).
A real-git squash fixture driving the production policy produced:
open_after_fresh_stamp: stale_snapshot_hits=0 synced_control_hits=1
expired_peer_stamps_no_records: host_a_hits=1 host_b_hits=1
old_stamp_default=['host-a']
old_stamp_nan=[]
Thus a recently stamped snapshot can omit a subsequently opened record and permit activation; once two hosts have exchanged stamps, both refuse every later update after the one-hour TTL, even with no owed records. The undeclared SUTANDO_WITNESS_MAX_AGE knob at upgrade.sh:118 also accepts nan/inf, defeating expiry, and violates the repository's manifest-config rule. Unblock by tying the stamp to a successfully pushed/versioned record snapshot, providing a reachable refresh/bootstrap path before the gate, validating a finite positive configured bound, and testing open-after-stamp plus mutually expired peers through the real two-workspace upgrade path.
[P1 blocker] The shared mutable-state contract still permits valid-key collisions, malformed closure state, path escape, and concurrent publication failure. tombstones() validates only repo/head/witness and ignores the writer's path, host, owed_by, closed_by, and timestamp contract (src/witness_owed.py:122-156); stale_hosts() likewise ignores the stamp's host/path agreement (:172-190). Record filenames replace / with - (:81-82), which is not injective for supported repository names. Host is checked only for non-emptiness before becoming a path component, and _atomic_write() gives every writer the same .tmp name (:97-115). Controls against the exact head showed:
malformed_tombstone: before_hits=1 after_hits=0
path_payload_mismatch_stamp: stale_hosts=[]
valid_repo_key_collision: same_path=true first_repo_hits=0 stored_repo=a/b-c
host ../../escaped: resolved_inside_workspace=false
concurrent_atomic_writers: errors=['FileNotFoundError'] final_exists=True
The tombstone used a wrong filename, owners and timestamp but silently cleared the open record; valid repos a-b/c#7 and a/b-c#7 mapped to one file, leaving the first deployment ungated. The concurrency result is a barrier-forced legal interleaving of two production _atomic_write calls. Unblock with full path/payload validators for every artifact, an injective key encoding, a validated single host path segment plus resolved containment, and unique temporary files/locking for read-modify-write transitions. Add mutation and concurrency controls against the production writers.
[P1 process blocker] This PR cannot use the exception it is introducing. Current origin/main still has zero deployment-gate references and retains the strict post-restart requirement at lesson 15; the new text itself says the exception is unavailable until the gate is live on every deployment host (REVIEW.md:270-272). The PR body explicitly says no exact-head restarted-service round trip and no owed record were supplied. My local bare-remote upgrade.sh --no-restart discrimination confirmed both the need and the basic new refusal:
parent_with_owed_record: rc=0 head_advanced=true
head_with_owed_record: rc=4 head_advanced=false
head_after_close_control: rc=0 head_advanced=true
After the implementation blockers are fixed, unblock this process gate with a real exact-final-head post-restart round trip, or split and deploy the gate under the existing rule before separately proposing the exception.
[P2 blocker] The emitted recovery command is not runnable. upgrade.sh:132 and REVIEW.md:269 tell the operator to use close ... --witness <url>, but the CLI requires --host (src/witness_owed.py:362-363); that documented shape exited 2 with the following arguments are required: --host. The stale-stamp error also offers no publication recovery. Make every refusal print a complete command appropriate to record, tombstone, or freshness failure.
Worst case: a peer activates a live-path regression before the owed record reaches it, dropping owner messages/tasks or wedging delivery; malformed closure state or a key collision can remove that hold silently. Conversely, aged peer stamps can prevent every host from pulling an urgent repair. Retaining the existing merge-time witness gate until publication is authoritative and the final head is witnessed mitigates both directions.
Verification: HEAD matched the requested SHA. Merge-base with origin/main was 5a6867f674702fa498bba1ea62d9bb18890c1c99; the first of 10 topic commits directly parents it, so no stack was detected. Local origin/main was 44 commits ahead and the merge interaction was clean; I inspected its changed sync path as part of the cumulative interaction. python3 tests/witness-owed.test.py -v ran all 24 named tests and passed; review-preflight tests ran 27/27; the review-check runner passed 79/79; topic review-checks, state-path adoption, src-map, Python-3.9 annotations, shell/Python syntax, and git diff --check passed. The manual added-line host-path scan found 0 hits and its synthetic /Users/reviewer/... control found 1. tests/self-upgrade.test.sh could not start because tmux is unavailable; the real local-remote --no-restart harness above exercised the implicated pull/refusal path instead. Preflight's prior-art lookup reported COULD NOT CHECK because GitHub access was deliberately unavailable; I inspected the supplied reviews/comments and zero inline comments. The supplied exact-head CI/CLA rollup reports green, but I did not query hosted CI under the required no-network scope.

…yment path refuses to activate over REVIEW.md lesson 15's first-deploy gate was a sentence in a PR thread that self-upgrade never read. src/witness_owed.py keeps the owed witness under <workspace>/state/witness-owed/ (open / check / canary / close); upgrade.sh runs check before it pulls and exits 4 when the target head newly contains an owed PR, unless --canary declares this host as the one producing the witness. Eligibility narrows to a pasted provisioning failure (installer, detached worktree, disposable target all unavailable), and the author-facing contracts in CONTRIBUTING.md, AGENTS.md, CLAUDE.md and the PR template point at the exception.
…er when --workspace is omitted
… diff coverage; one subprocess case keeps the entry point honest
Records live under the carried hosts/<host>/witness-owed/ subtree and every host's directory is read, so one host's record refuses activation on all. Containment recognises a merge (head ancestry), a squash (merge subject '(#N)') and a rebase (body naming the head); an unfetched head is not an error, a broken repo or bad ref is and blocks. Only the owing host may declare itself the canary. upgrade.sh fails closed when the workspace, host label, python or helper cannot be resolved, and calls the canonical python-bin. Lesson 15 gains the bootstrap precondition: the exception is usable only once the gate is live fleet-wide.

…ts writers keweichen's round-5 P1 on the mutable-state contract, all five reproductions fixed and each one mutation-controlled. - A tombstone CLOSES a peer's record, so it is now validated exactly as hard as one: full schema, filename/path agreement, both owners as real host segments, ISO stamp, and a refusal when owed_by == closed_by (a host tombstoning its own record bypassed close_record entirely). Three fields were checked before, so a misnamed tombstone with no owners silently cleared an open record. - Record filenames percent-encode instead of replacing `/` with `-`, which was not injective: `a-b/c#7` and `a/b-c#7` mapped to one file and the first deployment went ungated. - `host` is validated as ONE ordinary path segment before it becomes a path component, and records_dir asserts resolved containment; `../../escaped` resolved outside the workspace on a bare non-empty check. - A `.published` stamp naming a different host is no longer that directory's freshness evidence. - `_atomic_write` gives every writer a pid+uuid tmp name. Two concurrent production writers raced on the single shared `.tmp` and the loser raised FileNotFoundError. P2, same review: every refusal now prints a runnable command. The documented `close ... --witness <url>` shape exited 2 because the CLI requires --host; both the refusal text and REVIEW.md now carry the full close and tombstone forms, and the stale-view refusal offers `publish`. SUTANDO_WITNESS_MAX_AGE is validated finite-positive at the point of use — nan and inf parsed as floats and defeated expiry outright. Its manifest declaration is still owed. Still open from the same review and NOT claimed here: P1 #1 (`.published` is not a publication barrier) and P1 #3 (the exact-final-head post-restart witness this PR owes itself).

…a clock keweichen's round-5 P1-1. `.published` carried only a timestamp, so it could not say WHAT was published: a record opened one second after the stamp still read as a published view, and his squash fixture measured exactly that (`open_after_fresh_stamp: stale_snapshot_hits=0`). - The stamp now carries `records`, a content digest of that host's whole subtree. A mutation un-publishes the host BY CONSTRUCTION rather than by waiting for a clock, and `unpublished()` names it. - A peer whose stamp does not describe the records that arrived with it is stale. A fresh timestamp beside changed records is not a published view. - The gate reports THIS host's own unpublished records separately, because that is the one staleness the operator running the updater can fix, and the refusal says how. - A host with nothing to publish is never unpublished. Treating an absent stamp as unpublished would make every record-free host block itself, which is a fleet-wide deadlock rather than a safety property — the shape of his `expired_peer_stamps_no_records` result. Wiring, so the stamp is a claim a peer can actually check: - The pre-gate refresh is a full sync tick, not `--pull-only`. Pulling alone never publishes this host, so a fleet of pull-only updaters ages every stamp out and then refuses forever. This is the reachable refresh path his review asked for: every upgrade attempt republishes before it reads the fleet. - The stamp is written BEFORE that sync, so the records and the claim that peers can see them travel together. A stamp pushed without its records claims something false. - A canary declaration mutates this host's record, so it re-stamps before the gate reads it back; otherwise the gate refuses the host the canary names. - The post-pull stamp is dropped. `git pull` moves code, never this host's records, and the synchronous push it needed delayed the restart handoff past its latency budget (self-upgrade.test.sh case C caught this). Five mutation controls, each reverted in turn: no digest in the stamp, no peer digest check, gate ignoring its own unpublished records, `--pull-only` restored, and the unpushed post-pull stamp all fail the suite. Still open from the same review: P1-3, the exact-final-head post-restart witness this PR owes itself. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…re the records fresh?" The witness-owed gate refreshes the fleet's records by running the vault sync and reading its exit code as freshness. `scripts/sync-workspace.sh`'s default tick cannot answer that question: it runs `_pull_only_impl || true` by design (a peer whose pull is refused must still publish its own state) and returns the PUSH's rc. A pull refused by the mass-deletion tripwire therefore exits 0, and the gate activates the very head an owed record was holding. The defect is the seam, so the fix is in the script that owns the legs, not in the caller: `--pull-strict` runs the same two legs and lets the pull leg answer (exit 3), leaving default push semantics untouched for every existing caller. Sync that never ran is not a fresh view either, so strict also refuses when cross-machine sync is disabled. `upgrade.sh` asks for the strict reading and names which leg failed. Reported by keweichen, confirmed in source from both ends by john-the-dev.

Approving at 872658d52 — the refresh-bypass is fixed at both ends, and the opt-in is pinned. Releasing my block.
Thank you for picking this up; I asked whether it still had an owner rather than nudging, and you rebased and fixed it inside the hour.
Both halves, verified
The producer captures the pull outcome instead of discarding it:
@3fb8ed8e4 _pull_only_impl || true # pull failures shouldn't block push
@872658d52 _pull_only_impl || _pull_rc=$?
…
if [ "$_mode" = "strict" ] && [ "$_pull_rc" != "0" ]; then
echo "sync-workspace: STRICT FAILURE — pull leg exited $_pull_rc…"; return 3
and — the half that actually mattered for my block — the caller opts in:
# its zero says nothing about whether peer records arrived (exit 3 = pull leg).
GATE_SYNC_RC=0
bash "$REPO/scripts/sync-workspace.sh" --pull-strict || GATE_SYNC_RC=$?
if [ "$GATE_SYNC_RC" = "3" ]; then
echo "self-upgrade: ABORT — vault sync's PULL leg failed…"; exit 4Keeping the default as push semantics, with the reason written down — a host whose peer is broken still has to publish its own state — is the right call. A fix that made every caller strict would have traded a silent bypass for a fleet that stops publishing when one peer breaks.
The opt-in is pinned, which is what stops this regressing
A --pull-strict that any refactor can quietly drop from the call site would put the bypass straight back. So I mutated exactly that:
remove `--pull-strict` from upgrade.sh's call (sha 725da713ab -> 482f3b9e76)
tests/self-upgrade-sync-strict-gate.test.sh caught
Both new suites green at head: sync-workspace-pull-strict and self-upgrade-sync-strict-gate.
A method note against myself
I checked whether the caller opted in with '--strict' in upgrade_sh and got False at both revisions — which reads exactly like "the caller still never opts in", i.e. my block unfixed. The flag is --pull-strict, which does not contain --strict. Printing the actual call-site lines instead of trusting the boolean is the only reason I did not re-block a PR you had already fixed.
@keweichen's original P1 was the real one here and I only confirmed it; worth saying so on the way out.

Saying the boundary out loud this time rather than after. |
Five of keweichen's round-5 blockers, each fixed where its policy lives. P1 publication contract: `open --publish-with <cmd>` stamps, runs the caller's push synchronously and verifies it; a failure withdraws the stamp and exits 6, so an unpushed hold is loud and its own host cannot activate. The module docstring states what "published" means and the four conditions under which the gate may trust a peer's directory. P1 checked ref != pulled ref: upgrade.sh pins `$TARGET_SHA` right after the fetch, gates that object, and fast-forwards with `git merge --ff-only "$TARGET_SHA"` — no second fetch between the decision and the activation. P1 serialization: `record_lock()` (flock, per host+record key) wraps open/canary/close, and close compare-and-swaps before it unlinks, so a writer that ignores the lock still cannot delete bytes it did not archive. P1 host label: `validate_host()` follows the real contract — one path segment, ends trimmed only — so the legal `My Mac` is accepted while `/`, `.`, `..` and control characters stay refused. P2 declaration + isfinite: `SUTANDO_WITNESS_MAX_AGE` is declared in the new `skills/self-upgrade/manifest.json` config block (env > manifest > built-in); the shell's parallel numeric rule is gone and `validate_max_age()` enforces `math.isfinite()` at the owning Python boundary. P2 recovery guidance: health-check's three refresh prescriptions now name the gate-aware updater instead of a bare `git pull --ff-only`.

Changes requested at 75460d19a8910f1a04d3d9a258048b0a5c50287f; not merge-ready. The strict-pull, pinned-target, cooperating open/close serialization, spaced-host-label, finite max-age and recovery-guidance repairs are verified. One publication-contract blocker remains, with a production-transport reproduction below. This is a COMMENT review because this login authored the PR.
[P1] src/witness_owed.py:328-331 accepts a successful sync that uploaded neither the hold nor its stamp. publish_push() verifies only the local digest and the subprocess exit code. The documented sync-workspace.sh --push-only command can succeed while its effective carrier set excludes hosts/*/; it reports a clean, up-to-date remote even though the newly written witness record is ignored. This is also reachable with an existing .git/info/exclude that sync refuses to regenerate after the carrier configuration changes.
I ran the actual witness_owed.py open ... --publish-with CLI and this head's actual sync/config scripts against a disposable workspace and bare Git vault. No transport was stubbed. The failing case used the supported vault.sync.include: ["notes/"]; the control added hosts/*/ and explicitly regenerated the scratch exclude file with --force-gitignore:
case open rc local stamp hold in remote tree stamp in remote tree
excluded-hosts 0 true false false
carried-hosts 0 true true true
excluded: sync-workspace: nothing to push (clean working tree, remote up to date)
control: sync-workspace: pushed to host/hostA/wsa
Both remote-tree queries succeeded. Thus the new recipe can return success without the fleet-wide hold required to justify a witness deferral. Worst case: another host activates the unwitnessed change because it never receives either the record or an indication that this publisher is stale. The local stamp incorrectly remains valid, too.
Require the provider-side publication operation to verify that the exact required record/stamp bytes are carried and present at the acknowledged remote revision; pass that verified result into the shared policy. If the effective carrier excludes them or remote verification fails, withdraw the stamp and return the documented publication failure. Pin this with the production sync path, including the excluded-file control; the current cp -R fixture cannot expose carrier filtering.
The late c3cffe761..75460d19 commit changes test invocation only; I read the entire delta and reran the witness suite and full-diff scan at the final head. Production source and the publication reproduction are unchanged.
Validation: witness suite 55 tests pass; pinned-target 12/12, strict-gate 11/11, production strict-sync 13/13, and live-checkout guidance suite pass. The shipped pinned-target and strict-sync controls reproduce their old bypasses, and the witness suite's disabled-lock/CAS control reproduces the lost hold. Full current diff and activated consumers inspected. Added-path/root/prose scan passes; a synthetic forbidden host path is rejected.
self-upgrade.test.sh is not a local pass: it twice fails its total elapsed-time <2s assertion (6s, then 3s). Its earlier assertions already verify the restart marker, advancing heartbeat and surviving durable tmux session, so that timing failure alone does not establish an inline restart regression. The author's real post-restart witness remains explicitly absent in the latest update and is still required. No live services or contributor branches changed.

[P1] Verify publication of the required remote bytes. A production --push-only invocation with a carrier excluding hosts/*/ returns zero while neither this hold nor .published is present in the remote tree; the local digest still matches, so this branch falsely accepts publication. See the review body for the real-transport failing/control matrix.

REQUEST_CHANGES on exact head 75460d19a8910f1a04d3d9a258048b0a5c50287f — not merge-ready. The pinned-target, mass-deletion strict-pull, serialized writer, host-label, finite max-age, and recovery-guidance repairs are verified, but two fleet-gate bypasses remain, and this live-path head still lacks its required witness.
[P1 blocker] open --publish-with accepts success without publishing the required bytes. src/witness_owed.py:328-331 treats a zero command status plus a matching local digest as publication. That cannot prove the record or stamp reached the vault. scripts/sync-workspace.sh:27-42 explicitly supports an include list that replaces the defaults, and its push path can therefore ignore hosts/*/ while returning success. all_records_dirs() at src/witness_owed.py:127-132 only sees host directories that arrived, so a peer receives neither a hold nor a stale-host sentinel.
I independently ran the exact witness_owed.py open ... --publish-with CLI, current config resolver, and production sync script against a local bare vault:
carrier open rc local stamp remote hold remote stamp
["notes/"] 0 yes no no
["notes/", "hosts/*/"] 0 yes yes yes
excluded: sync-workspace: nothing to push (clean working tree, remote up to date)
control: sync-workspace: pushed to host/carried/carried
This independently confirms the existing exact-head inline finding; the formal block is still needed. Keep provider verification at the sync edge: publication must refuse unless the effective carrier includes the required subtree and the acknowledged remote revision contains the exact record/stamp digest. On failure, withdraw the local stamp and return exit 6. Pin both the excluded-carrier case and the carried control through the production sync path.
[P1 blocker] --pull-strict still returns zero when the lock prevents every leg from running. acquire_lock() exits 0 for an active or freshly-created lock at scripts/sync-workspace.sh:383-409; _bidirectional_tick strict calls it before _pull_only_impl at line 1596. Consequently upgrade.sh:137-144 reads “another instance is running, skipping” as a fresh fleet view.
A local bare-vault fixture used the production updater, sync script, and witness helper. The vault already contained the peer's owed record; the deploying workspace did not:
vault_contains_hold=yes
busy_upgrade_rc=0 head_advanced=yes local_hold=no
lock_line=sync-workspace: another instance is running, skipping.
after_unlocked_strict_pull local_hold=yes helper_check_rc=3
check=witness owed: owner/repo#77 ...
The fresh no-PID lock models the legal interval after mkdir and before the holder writes its PID. The ordinary live-holder path has the same zero exit. Preserve the default cron's skip-success semantics, but a strict caller must wait/join or return 3 whenever its own pull did not complete. Add an upgrade-level control with a remote peer hold and an active sync lock.
[P1 process blocker] This PR cannot bootstrap through the exception it introduces. The merge-base rule at REVIEW.md:266-279 requires a real restarted-service round trip before approval. The new text itself says the exception is unavailable until the gate is live fleet-wide (REVIEW.md:304-306), while the supplied exact-head body explicitly says no live witness or record was provided. I also exercised the merge-base updater with an open record present:
parent_rc=0 head_advanced=yes owed_record_present=yes gate_mentions_at_parent=0
After the implementation blockers are fixed, supply an exact-final-head post-restart round trip, or split the gate implementation, deploy and witness it under the existing rule, then propose the exception separately.
Worst case: a valid deferral command reports success while peers receive no hold, or a scheduled sync overlaps self-upgrade and the updater activates an owed live-path regression over a stale view. Owner messages/tasks can be dropped or delivery can wedge without a visible gate failure. Retaining the existing merge-time witness requirement until remote publication and strict refresh are authoritative mitigates that disruption.
Verification: HEAD matched; merge-base with local origin/main is 4b02fbaf03a7dc456c8353acfb514985b1b1604d. Fifteen linear topic commits directly follow that base, so no stack was detected. Local origin/main has three later, disjoint commits; merge-tree interaction was clean. tests/witness-owed.test.py ran 55 tests, OK; pinned-target 12/12; strict-gate 11/11; strict-sync 13/13; the three focused health-check suites passed. Because this sandbox denies ps, the production-sync fixtures used a deterministic process-start shim; the busy-lock failure itself does not invoke it. tests/self-upgrade.test.sh could not start because tmux is unavailable. Topic review checks, the 79-case review-check runner, git diff --check, bash -n, and src-map validation passed; local ruff and shellcheck were unavailable. The added-line path scan found only env shebangs and the explanatory /var→/private/var comment, no host-specific operational path; the synthetic /Users/ control was rejected. Preflight ran first but could not query GitHub in this no-network checkout; I inspected the supplied reviews and inline comment instead. The supplied hosted rollup is green but was not independently queried.

Rebased onto
origin/main(4b02fbaf0) after 5 days DIRTY. One conflict, in the generateddocs/src-map.md: main addedworker_identity.pyon the line this branch addedwitness_owed.py. Resolved by keeping both in alphabetical order;python3 scripts/gen-src-map.py --check→docs/src-map.md is up to date.The ask (@keweichen, round 5 P1; confirmed in source from both ends by @john-the-dev):
upgrade.shtreated a zero frombash scripts/sync-workspace.shas proof the fleet's witness-owed records were fresh, but the default tick runs_pull_only_impl || trueby design and returns the push's rc. A pull refused by the mass-deletion tripwire exits 0, so the gate activated the very head an owed record was holding.The fix, where the policy lives.
sync-workspace.showns the legs, so the strict reading is a mode there, not a re-implementation in the caller:A pull that never ran is not a fresh view either, so strict also returns 3 when cross-machine sync is disabled.
upgrade.shasks for--pull-strictand names which leg failed (pull → 3, anything else → push).Evidence — before/after on ONE fixture, real git, stubbed vault sync
tests/self-upgrade-sync-strict-gate.test.shbuilds the control from the shippedupgrade.shby substituting back the pre-fix call line, and asserts the control differs (a no-op substitution would test nothing). Both scripts then run against an identical fixture whose stub sync reproduces the real contract: refused pull → default exits 0,--pull-strictexits 3; a successful pull is what delivers the peer host's open record.tests/sync-workspace-pull-strict.test.shpins the mode itself against the production tripwire (host A deletes 60 tracked files; host B's pull is refused), with the default's unchanged behaviour as its own control:Suites at

src/witness_owed.py's docstring now states it rather than leaving it implied:opentakes--publish-with <command>and runs it synchronously; the transport isinjected, never named in the policy module. A failed push withdraws the stamp, so the host
stays visibly unpublished and its own gate refuses it, and the CLI exits 6.
openwithout--publish-withsays so on stderr instead of returning a silent success. REVIEW.md lesson15's recipe now carries the flag.
The first of those opens a hold on host A through the CLI, with

peer — no policy can publish bytes that were never sent. What changes is that this state is
now loud (exit 6) and self-limiting (the owing host cannot activate either).

75460d19a. This PR changesupgrade.sh, a live path, so under the existing rule it needs an exact-head restarted-service round trip before approval, and it cannot use the exception it proposes because every host runs the pre-gate updater until it lands (keweichen, 22:19Z). The owner is deciding between landing the gate first under the existing rule, with its own round trip, and re-proposing the REVIEW.md exception separately. Until then: no witness, no record filed. Nothing in this round was run against the live workspace, vault, or services — the new suites use scratch git repos and a stubbed sync.
