Collapsing them would let a stale +`review-pr-verdict.json` filed under the same PR number be read as telemetry about +a run `/review-pr` never performed. + +**This is the only relaxation the instrument buys, and it relaxes a check about +*which reviewer ran*, never a check about *whether this evidence describes this +code*.** Head-SHA binding, the release-anchor trust-head resolution, base-identity +equivalence and the evaluator's cumulative-diff and force-push primitives are +unchanged in substance for every instrument. + +#### Two deliberate deviations from #716's AC3 + +AC3 read: *"`/merge` gains PATH_3 with its own `TRUST_ANCHOR_ENUM` member (e.g. +`uberdev_premerge_trail`) so audit consumers can tell the tiers apart. PATH_3 +re-reads `gate-NN.json` and refuses on anything but a green verdict."* Its +`TRUST_ANCHOR_ENUM` clause shipped verbatim. The other two — a literal `PATH_3`, +and a `gate-NN.json` refusal — did not, and both departures are choices rather +than shortfalls. + +**1. There is no `PATH_3`.** The premerge tier is the *same* PATH_2 with a +different instrument value, not a third path. `commands/merge.md` states in two +separate places that there is no PATH_3 admin-bypass anchor, and two assertions in +`tests/merge.test.sh` — `M35.no-path3` and `M49.no-path3-bypass` — fail the build +if that literal appears anywhere inside the extracted Phase 1.4 body. Generalising +the existing path was therefore both the cheaper edit and the only one the tree +admits. Audit consumers still tell the tiers apart, via the anchor value. + +**2. `gate-NN.json` is a corroborator, not a gate.** `.uberdev/` is gitignored, so +a verdict living only there is unreadable on every clone but the producer's, and a +tier that *refused* without it would be unresolvable off the machine that ran +`/premerge`. So the load-bearing verdict moved into the commit body as the +`gate=green attempt=NN` token that (b) requires, and the JSON was demoted to +corroboration that never gates harder than sub-condition (c) — exactly as the +`review-pr` arm's audit JSON does not. + +Sub-condition (d) selects that corroborator **by `head_sha`, never by attempt +number alone.** The `*` in `.uberdev/premerge/*/gate-.json` is a run id, so +every earlier `/premerge` run in the same checkout left its own file at the same +attempt number; choosing by attempt would pick an unrelated run's evidence, find a +`head_sha` naming a different commit, and refuse a perfectly good trail as stale. +Only candidates that parse *and* bind to the trailer's SHA are classified. + +> **AMENDED 2026-08-24 — see §10 A8.** The glob quoted above is the +> canonical-root layout alone. Sub-condition (d) in +> `skills/merge-pipeline/SKILL.md` now enumerates four layouts — the same set the +> `review-pr` arm's verdict search already covers — so a `/premerge` run made +> inside a git worktree stays reachable when `/merge` runs from the main +> checkout. Widening the pool never widens acceptance: the `head_sha` binding +> this paragraph describes is still what selects. + +**The property a later reader should weigh before calling this a bug.** When no +candidate survives — the ordinary state on a clone that never ran `/premerge`, and +also the state when two bound candidates disagree — (d) emits an advisory `error` +event and then `gate_pass`. On such a clone the tier therefore rests entirely on +what the producer itself wrote: the `premerge-approved` label, and the +`Reviewed-by:` / `Reviewed-base:` pair in the anchor commit body carrying the +instrument, both delta endpoints and the `gate=green attempt=NN` token. That +is the accepted cost of keeping the tier resolvable anywhere, and it is bounded by +what the other sub-conditions still prove independently: (b.5) binds both endpoints +of the reviewed delta and refuses on label/trailer disagreement, and (c) is the +tamper detector and is untouched. Hardening (d) into a refusal would trade a +property nothing else supplies — off-producer resolvability — for one (c) already +provides. + +#### Three things this amendment deliberately does not do + +It adds **no auto-merge path, no auto-chain from `/premerge` to `/merge`, and no +flag implying either**. Relaxing a trust gate changes which PRs are *eligible*; it +never changes who pulls the trigger. `/premerge` still ends at a parked PR and +dispatches nothing. + +It relaxes **no structural check** — the list is under *What is dropped, and only +for the `premerge` instrument* above, and every item on it is untouched. + +It changes **nothing about `/goal`**. `lib/goal-state.sh` filters convergence +labels with `select(. == "uberdev-approved")`, an exact string equality that +`premerge-approved` cannot satisfy, so a premerge trail is invisible to `/goal`'s +convergence read by construction rather than by convention. + +**Supersedes:** §7's first paragraph, as struck there. §7's second paragraph +stands unchanged — `/premerge` and `/review-pr` still compose in that order, and +running `/review-pr` on a parked stack PR still upgrades the tier. + +### A8 — two A7 claims corrected against the shipped gate (2026-08-24) + +A7 was written in the same run as the code it documents and drifted from it +twice inside that run. Both corrections are recorded here rather than edited +away: the emit ordering in particular is a decision a later reader will want to +revisit, and they can only weigh it if the rationale that turned out to be wrong +is still legible beside its refutation. + +#### 1. The emit ordering resolves nothing — it picks which failure to take *(superseded by A9; the claim is kept verbatim, the correction is below it)* + +A7 held that running the gate before the `### 5a` version bump *"gets the release +commit proved rather than merely tolerated"*, on the reading that `/merge` +tolerates one `chore(release): vX.Y.Z` commit above the anchor once +`skills/merge-pipeline/lib/release-anchor.sh` has proved it inert. The tolerance +is real, and the ordering is what shipped. The conclusion drawn from them is not. + +`release-anchor.sh` is a refusal-first probe: it emits `RELEASE_ANCHOR=none` with +`diff_too_large` when the release commit's diff exceeds its bound, and with +`changelog_shape` when an inserted CHANGELOG line is not header-, bullet-, stub- +or blank-shaped. `### 5a` replaces the dated stub with real notes, which is the +shape that reason rejects. `skills/premerge-pipeline/SKILL.md`, under `### 5-trail +— the premerge trust trail`, records this repo's v0.56.0 and v0.30.4 as the worked +cases and states the consequence: `TRUST_HEAD` stays on the trailer-less release +commit, so PATH_2 (b) fails `trust_trail_trailer_missing`. + +Emitting **after** the bump does not rescue it. The 5-trail decision fence binds +the gate verdict to the SHA the gate read, so a release commit landing between the +two turns on the fence's own `head_moved` arm and publishes nothing. ~~Both +orders end with no trail `/merge` can resolve; the shipped order is a choice +between two failures, not a strengthening of either.~~ + +**The repair is in `release-anchor.sh` or in `### 5a`, never in the trail +fences** — either the anchor probe learns the shape of a real CHANGELOG notes +edit, or `5a` stops producing a commit the probe cannot read through. ~~Until one +of those lands, a stack PR's premerge trail is resolvable only on a run whose bump +was skipped. §9 carries it as open.~~ + +> **AMENDED 2026-08-24 — see §10 A9.** The struck conclusions expired inside the +> same run that wrote them.

The corroborator search is four layouts, not the repo root + +A7's second deviation from #716's AC3 quoted the corroborator as +`.uberdev/premerge/*/gate-.json`, root-relative and alone. Sub-condition (d) +in `skills/merge-pipeline/SKILL.md` enumerates four layouts — the canonical root, +`.claude/worktrees/*/`, `.worktrees/*/` and `worktrees/*/`, each carrying the same +`.uberdev/premerge/*/gate-.json` tail — which is the set the `review-pr` arm's +verdict search already covered. + +The root-only reading is not merely narrower than the gate; for the ordinary case +it is dead. `/premerge` writes its run dir under the checkout it ran in, so a run +made in a worktree leaves nothing at the main checkout's root: every such trail +falls down the Absent arm, and the `head_sha` selection A7 spends a paragraph +justifying never executes. Widening the pool changes no verdict — a candidate is +kept only if it parses *and* its `head_sha` equals the trailer's SHA — so what +A7 got wrong here is where the gate looks, never what it accepts. + +**Supersedes:** in A7, the clause *"so anchoring first gets the release commit +proved rather than merely tolerated"*, and the root-only reading of the +corroborator glob. The rest of A7 stands unchanged — the instrument-as-data +design, the `gate=green attempt=NN` token in the commit body, the Absent-arm +tradeoff and its bound, and the three things the amendment declines to do. + +### A9 — A8's first correction expired inside its own run (2026-08-24) + +A8 corrected two A7 claims against the shipped gate.

It measured, and it was right about what it +measured, which is precisely why this is a third note on the thread rather than a +rewrite of the second.

Still a + refusal, so A8's use of it survives as an example of *a* refusal — but not of + the one it named, and the replacement reason is the informative one. Its + README.md hunk rewrites a documentation sentence beside the badge bump, so the + refusal is about reviewed content changing under the trail, never about + CHANGELOG formatting. `changelog_shape` was merely reached first and masked it. + +#### Why the probe's answer moved + +Two changes, and only one of them loosens anything. + +**One size cap became three.** The revision A8 measured bounded the whole diff at +400 lines and inserted CHANGELOG lines at 40 — one number doing two unrelated +jobs, and set by the tighter of them. This branch bounds inert CHANGELOG prose at +2000, the whole diff walk at 4000, and the **code-bearing** half — everything +except CHANGELOG.md — at 200. That last bound is the one that carries security +weight, and it is **half** the 400 it replaces. The prose half widened and the +code half narrowed; describing this as the gate being relaxed reads only the first +of those. + +**Condition (7) stopped policing CHANGELOG prose line by line.** It now asserts +that the commit opens exactly one `## ` section and that it is the one the subject +names. That asserts strictly more about structure than the old per-line regex did, +and the regex was never a content control to begin with — any text behind a +two-byte bullet prefix satisfied it. What it actually policed was house +formatting, which is why `### 5a`'s real notes tripped it and why the trail looked +structurally dead. + +Neither change touches the boundary A7 and A8 both lean on: the path set is still +confined to the six version surfaces with rename detection disabled, and every +line of the five non-CHANGELOG surfaces must still be a pure version-token +substitution in the same order. + +#### What this leaves for the emit ordering + +The shipped order — gate and emit **before** `### 5a` — is the order that +resolves. A release commit that `bump-version.sh` produced and `5a` filled in with +real notes is tolerated, so `TRUST_HEAD` lands on the anchor commit and PATH_2 (b) +reads the trailer there rather than off a trailer-less head. + +A8's strike of A7's clause nevertheless stands, for a reason A8 did not give. A7 +argued that anchoring first gets the release commit *"proved rather than merely +tolerated"*. The probe has no such pair of states: `tolerated` **is** its success +value and the only alternative is `none`. The distinction that clause drew never +existed in any revision, so correcting the ordering's outcome does not revive it. + +What is left is a constraint on `5a`, not an open repair, and v0.30.4 is its +worked case: `5a` may touch the six version surfaces and, outside CHANGELOG.md, +may change nothing but version tokens. A bump that also rewrites a README sentence +refuses — correctly, because that sentence is reviewed content the trail would +otherwise carry across unreviewed. That is a rule for `5a` to keep, not a defect +for a later reader to go fix. + +#### A8's second correction, re-checked + +Accurate as written and unamended. Sub-condition (d) in +`skills/merge-pipeline/SKILL.md` enumerates the canonical root alongside +`.claude/worktrees/*/`, `.worktrees/*/` and `worktrees/*/`, each carrying the same +`.uberdev/premerge/*/gate-.json` tail, and still keeps a candidate only when it +parses *and* its `head_sha` equals the trailer's SHA. Widening the pool still +widens no acceptance. + +**Supersedes:** in A8, the conclusions of §1 as struck there — that both emit +orders fail, that a stack PR's premerge trail is resolvable only on a run whose +bump was skipped, and that §9 carries the item as open — together with +`diff_too_large` and `changelog_shape` as descriptions of the shipped probe. A8 +§1 remains accurate about the revision it measured, and it is kept for that.

(Named by instrument rather than spelled out: this file must never contain an emittable `premerge` trailer literal, for the same reason `tests/premerge.test.sh` P10 forbids a `review-pr` one in `/premerge`'s files — in prose as well as in a fence, because a whole-file grep cannot tell an honest citation from a forgery.) `/merge` Phase 1.4 PATH_2 is a **disjunction over instruments** — sub-condition (a) resolves an instrument SET from the labels and (b.5) admits the trailer whose instrument is a member — so leaving `premerge-approved` on the PR satisfies every PATH_2 conjunct: `/merge` resolves `TRUST_INSTRUMENT=premerge`, scopes Phase 2.5 discovery away as `not_applicable`, and emits `gate_pass` with `trust_anchor="uberdev_premerge_trail"` on a stack this review just blocked. Before the instrument generalisation that same PR carried no trail `/merge` would accept and was **structurally unlandable, server-side, on every clone**. Removing the label restores exactly that property, and it is the only artifact a RED run can use to restore it: it cannot rewrite the premerge anchor commit without a force-push, and it cannot refuse in the gate instead, because the RED verdict exists only in the gitignored `.uberdev/runs//review-pr-verdict.json` — absent on every clone but the reviewer's, and carrying no SHA of its own, since `ANCHOR_SHA` is bound only inside the artifact-1 anchor-emission block that RED skips. + +**The symmetric question, answered deliberately: GREEN and YELLOW must NOT clear `premerge-approved`.** They emit a fresh anchor on top of HEAD, so the trust head moves **past** the premerge anchor and the trailer `/merge` reads names `review-pr`.

Clearing it there would delete another command's trail on a run that did not contradict it, and would make the dual-label state that `skills/merge-pipeline/SKILL.md` Phase 1.4 (a) was repaired to resolve unreachable from the very compose order that repair exists to serve — re-opening the deadlock instead of closing anything. + +**Scope, stated rather than implied.** This clears labels on the RED arm of the trust-signal branch only.

A trail that wears one command's label and another command's trailer is not a trail either command emitted. **Membership, not arm order, is what decides a dual-labelled PR**: `/premerge` then `/review-pr ` is the documented compose order and leaves both trust labels on the PR, so a first-match resolution refused the very path the README and RFC 0021 A7 prescribe.

The fence runs this test where `TRAILER_SUFFIX` is bound, as a whole-string `case` glob rather than a `[[ =~ ]]` the zsh Bash tool would evaluate with `BASH_REMATCH` unset, folds the verdict into the same `TRAILER_CONTRACT_REFUSAL`, and captures the attempt number in `PREMERGE_GATE_ATTEMPT` for (d)'s corroborator lookup. Testing this regex against a `$TRAILER_SUFFIX` bound in some other shell is not a stricter reading of the check — it is a check that fails for EVERY premerge trail, which kills the tier as silently as the vacuous pass above opens it. This is the payload that keeps the premerge tier from resting on two bare literals, and it lives in the commit body rather than in `gate-NN.json` because `.uberdev/` is gitignored and a clone that never ran the producer has no such file. For instrument `review-pr` the suffix is optional in SHAPE only, never in meaning: an empty suffix is GREEN, the deferred-critical ` severity=critical-deferred count=N` form is YELLOW, and the paragraph immediately below gates on which of the two the anchor actually carries. + + **For instrument `review-pr`, a deferred-critical suffix requires the acknowledgement flag — and the commit body is the only place that fact survives a clone.** `$TRAILER_SUFFIX` must match `REVIEW_PR_DEFERRED_CRITICAL_REGEX` or be empty; the fence classifies it where the value is bound, prints the parsed count as `REVIEW_PR_DEFERRED_CRITICAL` (empty for GREEN), and folds an unrecognised third form into the same `TRAILER_CONTRACT_REFUSAL`. The acknowledgement itself is the CALLER's, because the flag is command-line state the fence may not assume — the same split by which `PREMERGE_GATE_ATTEMPT` is captured here and consumed in (d). **When the printed count is a positive integer and `ACCEPT_CRITICAL_DEFERRED_FLAG` was not passed, emit `gate_fail` with `data.reason="trust_trail_stale_sha"`, skip this PR before (c) dispatches, and continue the queue** — the same reason, and the same softness, that the evaluator's own critical-deferred gate produces from `phase2_5_critical_count > 0`, so the two paths agree and no `GATE_FAIL_REASON_ENUM` member is added. Read the count off the fence's printed output like every other value it resolves; a prose test over a name bound in some other shell compares empty to empty and admits exactly what it exists to refuse. **This is not a duplicate of the evaluator's gate — it is the only copy that survives distribution.** `review-pr-verdict.json` lives under gitignored `.uberdev/`, so in a worktree, on another machine, or after a fresh clone, discovery returns `audit_state=absent`, the evaluator skips its Phase 2.5 gate by design, a structural `PASS` reaches (d)'s absent arm, and the YELLOW lands with `--accept-critical-deferred` never read. That is the same hole `PREMERGE_GATE_TOKEN_REGEX` closes for the other instrument, and closing it here is what lets (a) admit `uberdev-approved-with-concerns` without re-opening the refusal the bare-literal label test used to deliver by accident. **The blocker-deferred override is NOT covered by this gate**: an OVERRIDE_GREEN run emits the GREEN triplet, so `override_reason` exists only in that same gitignored artifact and `--i-know-what-im-doing` stays unenforceable off the producing checkout until `commands/review-pr.md` writes the override into the trailer suffix too. + + **When either `$BASE_IDENTITY_REFUSAL` or `$TRAILER_CONTRACT_REFUSAL` is non-empty this fence REFUSES**: emit `gate_fail` with `data.reason` set to that value (`trust_trail_trailer_missing`, already in `GATE_FAIL_REASON_ENUM` — this fence adds no new member), skip this PR before (c) dispatches, and continue the queue.

The `*` before it is a run id, and every earlier `/premerge` run in the same checkout left its own `gate-.json` at that same attempt number — so choosing by `attempt=NN` alone selects an unrelated run's file, whose `head_sha` names a different commit, and refuses a perfectly good trail as stale. Widening the search widens the candidate POOL and never the acceptance: keep only the ones that parse AND whose `head_sha` equals `$TRAILER_SHA`, and classify on what survives. Three arms, and only the middle one is a refusal: + + - **Bound and green** — at least one candidate survived, the survivors agree, and their verdict is `green`. Surviving already means the file binds to `$TRAILER_SHA`, so this is evidence about the very commit the trailer names. Proceed to `gate_pass` with `data.trust_anchor="uberdev_premerge_trail"`. + - **Bound and disagreeing** — the survivors agree and their verdict is not `green`. Emit `gate_fail` with `data.reason="trust_trail_stale_sha"`. Local evidence that demonstrably describes THIS commit and contradicts the trailer is a genuine staleness signal, not a shrug. + - **Absent, unreadable or ambiguous** — nothing survived: no layout matched a file, no match parsed, no match bound to `$TRAILER_SHA`, or two that did bind disagree with each other so no single one is authoritative. `.uberdev/` is gitignored, so an empty result is the ordinary state on any clone that did not run `/premerge`, and an ambiguous one is not evidence of anything. Emit one `error` audit event with `data.reason="trust_trail_json_absent"` `data.pr=`, append the one-line run-summary advisory, and emit `gate_pass`. **This arm deliberately downgrades #716's originally-proposed `gate-NN.json` refusal to a corroborator-only check**: hardening it into a refusal would make the premerge tier unresolvable on every clone but the producer's, and the substitute payload is the `gate=green attempt=NN` token in the immutable commit body that (b) already required — so the tier never rests on a bare label plus a bare trailer. The JSON adds corroboration and never gates harder than (c), exactly as the `review-pr` arm does not. + + **Instrument `review-pr` — everything below is unchanged.** The artifact **whose top-level `.pr` integer field equals the current PR number ``** is **corroborating-only** — the JSON is local-only debug telemetry per D1 and `.uberdev/` is gitignored, so its absence on a fresh clone is by design (the trailer + (c) agent verdict are the load-bearing trust artifacts). This sub-condition MUST reuse only the closed controller state produced in Step (c.0): `DISCOVERY_STATE`, `PHASE2_5_AUDIT_STATE`, and cached `AUDIT_ARTIFACT_SHA`. It must not reopen the selected source pathname, reopen the snapshot carrier, rediscover, re-rank, or parse artifact JSON again. The canonical helper's search surface remains `.uberdev/runs/*/review-pr-verdict.json`, `.claude/worktrees/*/.uberdev/runs/*/review-pr-verdict.json`, `.worktrees/*/.uberdev/runs/*/review-pr-verdict.json`, and `worktrees/*/.uberdev/runs/*/review-pr-verdict.json`. It validates `RUN_ID_REGEX` before identity reads, accepts only integer `.pr`, and ranks by the timestamp prefix only. Expected-PR artifacts tied at the selected timestamp are accepted only when their securely captured bytes are identical. Valid artifacts for other PRs are ignored. Older unknown identity is harmless; newer/equal unknown identity is indeterminate. The check here is presence + cached shape; strict `"sha" == headRefOid` is RETIRED post-#78 — sub-condition (c) already does tamper detection via the trust-trail-evaluator's cumulative-diff heuristic, and (d) gating harder than (c) contradicted the fast-forward-fixup tolerance documented immediately below at "Honest fast-forward fixup commits..." (see issue #78). Two evaluation paths: - **JSON present (typed discovery FOUND=0).** Step (c.0) already validated the expected PR, top-level lowercase 40-hex SHA, Phase 2.5 fields, snapshot digest, and snapshot identity from one byte capture, then cleaned the private carrier. Use cached `AUDIT_ARTIFACT_SHA`; do not execute `jq`, the legacy path-taking parser, or any file read in this sub-condition. A missing/non-40-hex cached value is an impossible closed-receipt invariant break and emits `gate_fail` with `data.reason="trust_trail_json_sha_mismatch"` (the reason name is preserved post-#78 for audit-log compatibility but its scope is narrowed to **shape-malformed only**). On shape OK: proceed to `gate_pass`. **No equality check against `headRefOid`** — the JSON's role is corroborator-only; (c) owns tamper detection. - - **JSON absent for this PR (typed discovery ABSENT=1).** The single exhaustive Step (c.0) scan found no valid target artifact across the four helper-owned layouts; artifacts with valid integer identities for other PRs do not change this result. Emit one `error` audit event with `data.reason="trust_trail_json_absent"` `data.pr=`, append a one-line advisory to the run summary (`audit JSON absent for PR (fresh clone — corroborator unavailable; trailer + agent verdict are load-bearing)`), and emit `gate_pass` with `data.trust_anchor="uberdev_review_trail"`. The queue continues; no halt. `malformed` and `indeterminate` never reach (d), because the evaluator has already returned `INVALID / input_malformed`. + - **JSON absent for this PR (typed discovery ABSENT=1).** The single exhaustive Step (c.0) scan found no valid target artifact across the four helper-owned layouts; artifacts with valid integer identities for other PRs do not change this result.

The queue continues; no halt. `malformed` and `indeterminate` never reach (d), because the evaluator has already returned `INVALID / input_malformed`. **An unacknowledged YELLOW never reaches this arm either:** (b.5)'s commit-body suffix gate refused it before (c) dispatched, so a `gate_pass` here means the anchor's own suffix said GREEN — not merely that the corroborator was missing. **Old `data.reason="trust_trail_json_missing"` is RETIRED** post-#52 — the value remains declared in `GATE_FAIL_REASON_ENUM` for historical audit-log compatibility but is NEVER emitted (deprecation pattern; mirrors `admin_bypass`/`waiver_recorded`). **The strict `"sha" == headRefOid` equality check is RETIRED** post-#78 — `data.reason="trust_trail_json_sha_mismatch"` is still emitted for an impossible missing-or-malformed cached `AUDIT_ARTIFACT_SHA` (a shape failure only) but no longer for SHA-equality mismatches. Invalid run-id candidates are ignored before identity reads; JSON/identity/root/capture failures become `indeterminate` or `malformed` in (c.0) and never reach (d). Tamper detection is fully delegated to sub-condition (c) via the trust-trail-evaluator agent's cumulative-diff heuristic. This eliminates both the mutable-path TOCTOU and the (c)/(d) contradiction where empty-diff fast-forward fixups (or sibling-equivalent `git commit --amend`) PASSed (c) but FAILed (d), gating valid trust trails. -On all four sub-conditions met: emit `gate_pass` with `data.trust_anchor="uberdev_review_trail"`. Proceed. +On all four sub-conditions met: emit `gate_pass` with the `data.trust_anchor` that (c)'s PASS mapping derives from `$TRUST_INSTRUMENT` — `uberdev_review_trail` for `review-pr`, `uberdev_premerge_trail` for `premerge`. **This line SUMMARISES (c) and (d); it is never a second mapping.** It is also the copy an orchestrator reads when it skips the rows above, so re-hardcoding one instrument here stamps every premerge landing `uberdev_review_trail` and destroys exactly the tier distinguishability `TRUST_ANCHOR_ENUM` exists to provide — the same defect (a.5) already carries a paragraph about, one summary line further down. Proceed. Honest fast-forward fixup commits added between `/review-pr` and `/merge` (e.g., trivial typo fixes, comment touch-ups whose cumulative diff is empty) evaluate to `PASS` without forcing the user to re-run `/review-pr` — and `/review-pr`'s own end-of-run trust-trail emission rides this same path: it appends an empty anchor commit at HEAD whose body carries the trailer pointing at its parent (the actual end-of-run HEAD), so the cumulative diff between trailer-SHA and live HEAD is empty by construction → `PASS` (see `commands/review-pr.md` "Trust-Signal Emission" artifact 1). Sibling commits produced by `git commit --amend` (same parent, different SHA, identical tree) ALSO evaluate to `PASS` — the agent's Step 3 tree-diff check distinguishes sibling-equivalent rewrites from real history rewriting independently of the ancestor relationship; this covers user-side amends made between `/review-pr` and `/merge`. (`/review-pr` itself no longer amends post-v0.18.1 — the per-simplify-commit trailer + amend pattern is retired in favour of the empty anchor commit, which sidesteps the parent-vs-self SHA mismatch class of bugs.) Force-pushes that change the tree contents evaluate to `FORCE_PUSHED`.

They are separate tokens because they call for +different next moves: the first says the stack still has work in it, the last +says something touched the branch after the gate read it, and a run that +collapsed them into a blank row would withhold the one thing an operator can act +on. All four exit **0** — declining to emit is an ordinary outcome the run +continues past, not a failure of the fence. + +**The emit fence prints a different vocabulary, and `half_emitted` is in it.** +The four reasons above are the *gate* fence's whole set. The publication fence has +its own, and a controller that knows only the gate's has no arm for the state that +matters most. It prints `PREMERGE TRAIL=emitted ANCHOR= PR= +LABEL=premerge-approved` on success and exits **0** — `emitted`, past tense, not +the gate's `emit` — and `PREMERGE TRAIL=half_emitted` with +`REASON=label_unprovisioned` or `REASON=label_unapplied`, each carrying +`ANCHOR= PR=`, when the anchor reached the remote but the label did not. +Both of those exit **2**. Everything that refuses *earlier* than the push prints a +bare `error:` line, no `TRAIL=` token at all, and exits **2** — there is nothing +emitted for a token to describe. `### 5b — PARK`'s trust-trail row transcribes all +three forms, and `half_emitted` must never be collapsed into `none`: `none` says +nothing reached the remote, `half_emitted` says half of it did. + +**Past the push there is no rollback, and that is the design.** By then the anchor +is a pushed commit, and taking it back means force-pushing a branch other clones +may already have fetched — so both `half_emitted` arms report a state rather than +pretend to undo one. Leaving it standing is safe because the state fails +**closed**: `/merge` resolves PATH_2 from the label *and* the trailer, so an anchor +wearing no label resolves nothing. The recovery is to re-run the idempotent label +step, never to rewrite the branch. The ordering that produces the state is itself +deliberate — the push runs before the label because, of the two artifacts, the +irreversible one is the inert one and the one carrying the visible claim is the one +a re-run can still fix. + +**Before the push, every refusal unwinds its own anchor.** The anchor commit is +still local there, and 5a pushes this branch a few steps later, so one left behind +is one 5a publishes: a premerge trailer with no label and no gate anyone consented +to. Those arms `git reset --soft` back to the gated parent — `--soft` moves the +branch pointer and touches neither the index nor the working tree, so the +pre-commit state comes back whole, staged bytes included. One arm deliberately does +**not** unwind: the one that finds the anchor's parent is not the head the fence +read. A branch whose shape the fence cannot account for is one it must not rewrite, +so that arm refuses and leaves it for a human. + +**The write-guards all assert before the first write.** The PR number the anchor +names comes from `combined_pr` in the run directory's `manifest.json`, not from the +call site, and `jq -r` is not a validator: a manifest missing that key prints the +string `null` and exits **0**, so the `|| exit 2` never fires. Unguarded, the fence +would anchor `... for #null`, push it, and fail only at `gh pr edit null` — landing +squarely in the post-push state the paragraph above says cannot be undone. A +numeric-shape check refuses it first, exactly as the two-digit check on +`PREMERGE_TRAIL_ATTEMPT` refuses an unpadded attempt first: assert before the first +write, never repair after it. The fence also declines to trust the checkout it +inherits — it reads HEAD itself, refuses unless HEAD is on the stack branch named +in the run directory, and refuses unless the anchor it just made carries that same +head as its parent. + +**What the trail claims, and what it must never be read as claiming.** It says +`/premerge`'s clean gate was green on this exact head: blockers cleared, CI green +or absent, the stack not conflicting, and the evidence stamped with the branch's +own HEAD. It says nothing about the seven-lens review fanout, the +finding-verification pass or the CI-health phase — under `/premerge` none of them +ran, and the instrument field in the trailer is the thing that keeps the claim +honest rather than a convention someone has to remember. `/merge` resolves the +instrument from the label *and* from the trailer, refuses when the two disagree, +and records a green premerge trail under its own trust anchor, so an audit +consumer can tell the two tiers apart without reading either producer. + +**And a trail is still not permission to merge.** It changes which PRs `/merge` +is *able* to resolve a trust path for; it changes nothing about who decides that +a specific PR should land. `/premerge` parks the stack PR and dispatches nothing. diff --git a/plugins/uberdev/skills/using-uberdev/references/configuration.md b/plugins/uberdev/skills/using-uberdev/references/configuration.md index 660b410d..a7c3d889 100644 --- a/plugins/uberdev/skills/using-uberdev/references/configuration.md +++ b/plugins/uberdev/skills/using-uberdev/references/configuration.md @@ -211,7 +211,7 @@ dispatch.

Phase 1.4 trust resolution accepts EITHER `reviewDecision == "APPROVED"` (PATH_1, team / branch-protection path; required reviews + status checks anchor the trust) OR an uberdev trust trail bound to the PR's trust head, resolved by the `trust-trail-evaluator` agent (PATH_2, solo-dev / no-protection path). PATH_2 is generalised over the trail's **instrument** — the command that produced it, carried as DATA inside the trailer (`Reviewed-by: uberdev/@`) rather than baked into a fixed prefix — so it accepts a `/review-pr` trail (label `uberdev-approved` or `uberdev-approved-with-concerns`) and a `/premerge` stack trail (label `premerge-approved`) on the same terms. The label and the trailer must name the SAME instrument, and a `premerge` trailer must additionally carry a `gate=green attempt=NN` token in the immutable commit body, so that tier never rests on a bare label plus a bare trailer. The trust head is the PR's head SHA, except that one provably inert `chore(release): vX.Y.Z` commit on top is tolerated and read through (#364). The agent reads structural primitives — ancestor + diff-empty + log-empty — plus the caller-computed base-identity inputs that pin the reviewed delta's other endpoint (#440), and returns verdicts in `{PASS, STALE, INVALID, FORCE_PUSHED}`; a PASS lands `trust_anchor="uberdev_review_trail"` or `"uberdev_premerge_trail"` so an audit consumer can tell the two tiers apart.
