Scope note (maintainer edit, 2026-08-07): packages/eliza-computer was retired from this repository (moved to elizaOS/army) after this PR was reviewed. The terminalAttributionBlock validator fix described below now lives in SlopDotCash/slopdotcash#5. What this PR actually merges is only the surviving scripts/pr-evidence.mjs fix: evidence-row patching now inserts before a trailing attribution footer instead of appending after the marker (which broke marker-finality). Tests included.

Relates to #17610

Following the repository's own two contribution documents always produced an invalid attribution marker. The published ledger shows the scale: 3 valid against 64 missing-or-invalid of 67 eligible sources (95.5% failure), including PRs authored by @lalalune (#17424, #17555).

This changes no scoring — leaderboard.ts:1379 states that complete, partial, missing, and invalid attribution states "add no points." What was broken is the provenance dataset the attribution system exists to produce: attributions, attributionCoverage, and invalidAttributionMarkers currently describe almost nothing that actually happened.

Root cause

markerFooterError required exactly one of each visible row across the entire body. But .github/pull_request_template.md:28-37 already ships three of those labels as checklist rows, and SKILL.md says "complete every stable contribution-attribution row in the repository template and append this footer after the template" — where the footer repeats them. (The skill-revision regex accepts both Skill revision and Contribution skill revision, so the template row and the footer row both count.) Every label appears twice, length !== 1 fires, marker rejected — contributor did everything right.

The fix

Count footer rows only within the terminal attribution block: the contiguous run of label lines ending at the already-validated lane signature. A checklist row ninety lines above the footer is not a competing footer. Duplicate detection is deliberately unweakened — rows abutting the lane are inside that block and still collide, and the at-most-one-marker gate is untouched.

Proof

isolating the cause to a single line (real validator)

A. footer alone (no template rows):            valid=1 invalid=0
B. ONE template attribution row above footer:  valid=1 invalid=1  marker requires exactly one complete visible attribution footer
C. the real template's 3 rows above footer:    valid=1 invalid=1  marker requires exactly one complete visible attribution footer

end-to-end: real template + skill footer + the real evidence tool (before → after)

BEFORE
1. .github/pull_request_template.md + footer appended after it:  valid=1 invalid=1  marker requires exactly one complete visible attribution footer
2. after patchRow on a template-present row:                     valid=1 invalid=1  (same)
3. after patchEvidenceHead + a row absent from the body:         valid=1 invalid=1  (same)

AFTER
1. .github/pull_request_template.md + footer appended after it:  valid=1 invalid=0
2. after patchRow on a template-present row:                     valid=1 invalid=0
3. after patchEvidenceHead + a row absent from the body:         valid=1 invalid=0

suite

$ bun test packages/eliza-computer/src/lib/leaderboard.test.ts
 54 pass
 0 fail

(52 pre-existing, unchanged, plus two new: the real template's rows above an appended footer validate; adjacent duplicated rows still fail with the original reason.)

A second, related defect — reported, not fixed here

scripts/pr-evidence.mjs patchRow:332-339 and patchEvidenceHead:353-364 append when a marker is absent, which relocates content after a trailing attribution footer and trips the separate "marker must be the final source content" rule. I hit this on four of my own PRs and repaired them by hand; no instruction tells a contributor to re-order. It is left out of this PR to keep the diff to one concern — happy to send it as a follow-up making those functions insert before a trailing footer, if maintainers want it separately.

Independent review — approved

Verified on the trusted control checkout (not trusting the summary):

• Diff audit: terminalAttributionBlock walks backward from the validated lane signature, collecting only contiguous label lines separated by blank space; it stops at the first non-label line. Counting then happens against that terminal block only, so the PR template's checklist rows (which legitimately repeat Client / agent tooling, Skill revision, Attribution status per the repository's own template + SKILL.md instruction to append after the template) no longer collide with the appended footer.
• Duplicate detection unweakened: rows abutting the lane signature remain inside the block and still collide with the original marker requires exactly one complete visible attribution footer reason — covered by the new adjacent-duplicate test.
• Tests reproduced: bun run --cwd packages/eliza-computer test on the PR head → 10 files / 161 tests pass (159 pre-existing + 2 new). The new cases cover the real template + appended footer (valid) and adjacent duplicated rows (still rejected).
• Evidence: before→after transcripts with the real validator and the real evidence tool are verbatim and reproducible; the second related defect (pr-evidence.mjs append vs insert) is honestly reported as out-of-scope with a clear follow-up offer rather than silently bundled.
• Closes #17610 is referenced; no scoring behavior changes (add no points preserved).

Approvable from my side.

[lalalune]

The terminal-block validator change is sound, but this PR is not sufficient to Closes #17610 at its current head. The issue explicitly includes the independent scripts/pr-evidence.mjs composition defect in its proposed fix and acceptance criteria: absent evidence rows or an absent Evidence Gate cause patchRow / patchEvidenceHead to append after the terminal eliza-computer-attribution marker, immediately violating the marker-finality rule. The PR body acknowledges that defect but leaves it unresolved, so merging this would close an issue whose required red/green coverage still fails.

Please either implement the footer-aware insertion plus patchRow / patchEvidenceHead marker-finality tests here, or change Closes #17610 to a non-closing relation and keep #17610 open for the remaining acceptance criteria. The current branch also needs rebasing and exact-head CI after that choice.

[sharkwon]

Follow-up — maintainer gate confirmed valid; my approval was scoped to the validator half only

Independently re-verified scripts/pr-evidence.mjs on origin/develop after @lalalune's request: the gate is real. patchRow (line ~333, marker-absent branch) does return \${body.trimEnd()}\n\n${marker}\n${line}\n`andpatchEvidenceHead(line ~353, no# Evidence Gatebranch) doesreturn `${body.trimEnd()}\n\n${marker}\n`— both append after a trailing attribution footer, violatingmarker must be the final source content and failing acceptance criterion 4 of #17610 ("patchRowandpatchEvidenceHeadleave the attribution marker as the final content when one is present; covered red/green"). The PR body itself declared this defect out-of-scope, which is exactly whyCloses #17610` cannot stand at this head.

My APPROVED above covered only what I could verify: the terminalAttributionBlock validator change (sound, 161/161 tests reproduced). It was never a verdict on the full #17610 close.

Checklist the author needs (smallest coherent scope)

1. Footer-aware insertion in patchRow: in the marker-absent branch, detect a trailing attribution footer (the eliza-computer-attribution:v1 marker or its visible — [lane] signature) and insert the new evidence row before it instead of appending after it:

   // pseudo-patch for scripts/pr-evidence.mjs patchRow marker-absent branch
   const footerAt = body.search(/<!--\s*eliza-computer-attribution:v1/i);
   if (footerAt !== -1) {
     const head = body.slice(0, footerAt).trimEnd();
     const tail = body.slice(footerAt);
     return `${head}\n\n${marker}\n${line}\n\n${tail}`;
   }
   return `${body.trimEnd()}\n\n${marker}\n${line}\n`;

2. Same treatment in patchEvidenceHead for the no-# Evidence Gate branch: insert the head marker before a trailing attribution footer.
3. Red/green tests for both: body ending in a full SKILL.md footer + absent row → marker stays final (green); the same on the old code path → red. Mirror the existing leaderboard.test.ts style so the two defects share one harness.
4. Then either keep Closes #17610 (with both halves covered) or downgrade to Relates to #17610 if the pr-evidence fix lands separately — maintainer's call, but the acceptance criteria demand the evidence-tool half before close.
5. Rebase onto latest origin/develop and re-run exact-head CI after the change.

Happy to review the follow-up head once it lands.

[ss251]

Took the first arm: the pr-evidence.mjs composition defect is now fixed in this PR, with the marker-finality tests, so Closes #17610 stands on all five of its acceptance criteria.

What changed since your review

• c29afe8c9 — scripts/pr-evidence.mjs gains findTrailingAttributionFooterStart, which recognizes the exact terminal-footer shape the validator enforces (v1 marker as final content, one lane signature above it, the contiguous attribution label rows above that, optional ---). Both patchRow and patchEvidenceHead now insert before that footer when their target marker is absent, and keep byte-identical append behavior when no footer is present (asserted against the pre-existing fixtures).
• 95616d16f — the criterion-1 test now reads the shipped .github/pull_request_template.md from disk (not a representative excerpt) and appends the SKILL.md footer, so the test breaks if either document drifts back into incompatibility.

Cross-validated against the real validator, both builds — not the tool's own tests; assessModelAttribution imported from this branch's leaderboard.ts and from origin/develop's, fed the same bodies:

=== baseline: shipped template + SKILL.md footer, untouched ===
develop validator: {"valid":1,"invalid":1,"reason":"marker requires exactly one complete visible attribution footer"}   <- the #17610 defect
branch  validator: {"valid":1,"invalid":0}

=== develop's patchRow+patchEvidenceHead (append-after) ===
develop validator: {"valid":1,"invalid":1,"reason":"marker must be the final source content"}   <- the composition defect
branch  validator: {"valid":1,"invalid":1,"reason":"marker must be the final source content"}

=== this branch's patchRow+patchEvidenceHead (insert-before) ===
branch  validator: {"valid":1,"invalid":0}
marker final in patched body: true

The old tool's output is rejected for marker finality under both validator builds; the new tool's output is fully valid under the fixed validator, and the finality complaint is gone under develop's build too (its remaining complaint on these bodies is the template-collision defect this PR's validator half fixes).

#17610 acceptance criteria, one by one

1. Real-template body validates valid=1 invalid=0 — executable test against the shipped file (accepts the SHIPPED pull_request_template.md with the footer appended), red against the pre-branch validator, green here.
2. Two complete footers still fail — still rejects duplicated footer rows adjacent to the marker (no weakening).
3. Footer-only bodies still validate — every pre-existing acceptance test in the suite still passes (55/55, up from develop's 52).
4. patchRow/patchEvidenceHead marker finality — implemented + covered red/green (node --test scripts/pr-evidence.test.mjs: 35 pass; against develop's tool the footer-aware suite fails).
5. bun test on the leaderboard suites: 96 → 97 tests pass across leaderboard.test.ts + generate-leaderboard.test.ts; scripts/pr-evidence tests 35/35.

Exact head: rebased on f1f47e73f, head 95616d16f, evidence head marker updated to match. The workflow runs for this head are waiting in the fork-PR run-approval queue (the previous Develop PR Gate expired polling "no GitHub Actions check run" for every lane); once runs are approved the full gate will populate against this head — no further code changes queued from my side.

Reviewed head 95616d16f8fa37dbf56fd450e4e1b3d4d7dae3c3 (4 files, +399/-8).

The diagnosis is right and the fix is the correct shape. Scanning the whole body for attribution rows made the shipped PR template and SKILL.md's "append this footer after the template" mutually exclusive, which is why 64 of 67 eligible sources went invalid (#17610). Anchoring at the validated lane signature and walking backwards while requiring only whitespace between adjacent members is a well-chosen bound — it keeps the template's checklist rows out without introducing a positional heuristic like "last N lines". Evidence gate passes with real artifacts.

I have some incidental standing here: I hit the sibling validator (scripts/check-agent-comment-attribution.mjs) from the review side earlier today and had to trace its regexes to understand a rejection, so I read this one closely.

The "duplicate-footer detection is unweakened" claim is narrower than stated

// Two genuinely adjacent footers still collide here, so duplicate-footer
// detection is unweakened.

That holds for duplicated rows, which is what the new test exercises — and I checked why it passes. In still rejects duplicated footer rows adjacent to the marker the two row-groups have nothing between them, so the backwards walk crosses from the second group straight into the first, counts two of each label, and rejects. Correct.

It does not hold for two complete footers, because a complete footer ends with a lane signature, and a lane signature is not an attribution label:

if (!ATTRIBUTION_LABEL_PATTERN.test(record.normalized)) break;

ATTRIBUTION_LABEL_PATTERN matches only AI provider/model / Client \/ agent tooling / Contribution skill revision / Skill revision / Attribution status. A lane line such as — [some-lane] matches none of them, so the walk stops there.

Concretely, for a body shaped like:

AI provider/model: …          ← footer 1
Client / agent tooling: …
Contribution skill revision: …
Attribution status: self-reported
— [lane-one]
AI provider/model: …          ← footer 2
Client / agent tooling: …
Contribution skill revision: …
Attribution status: self-reported
— [lane-two]
<!-- eliza-computer-attribution:v1 {...} -->

beforeMarker ends at lane-two; the walk collects footer 2's four rows, then hits lane-one, fails the label test, and breaks. footerBlock contains exactly one of each label, so markerFooterError returns clean — two complete visible footers, accepted as one.

In practice this is still caught, but by a different rule: appending a real footer twice also produces two markers, and allMarkerMatches.length !== 1 rejects that. So the protection has quietly migrated from the label-count check to the single-marker check. That is fine as a design — it just means the comment overstates what this function guarantees, and the last line of defence against a stacked visible footer is now the marker count alone. If someone later relaxes the marker rule (say, to tolerate a quoted marker in a review body), this stops being covered with nothing failing.

Two options, either works:

• Reword to what is actually true: adjacent duplicate rows still collide; two complete footers are caught by the single-marker rule rather than here.
• Or make the claim true by treating an intervening lane signature as part of the block rather than a terminator, so the walk continues through it and counts both groups.

Worth a test either way — the same fixture as above with one marker, asserting marker requires exactly one complete visible attribution footer. Right now nothing pins the behaviour for a lane-separated duplicate in either direction.

Non-blocking

Skill revision and Contribution skill revision both match the label pattern. That is deliberate (the template ships the short form, the skill footer the long one), but it means a body whose template row happens to sit immediately above the appended footer with no blank line between them contributes a second Skill revision to the block and is rejected as a duplicate. The contiguity check makes this unlikely in the shipped template — and your accepts the SHIPPED pull_request_template.md with the footer appended test pins the real layout, which is the right guard. Just noting the sharp edge: the fix's correctness depends on the template keeping non-label content between the checklist and the footer, so a future template edit that closes that gap would silently re-break #17610. A comment on the template rows saying "do not place these adjacent to the appended footer" would make the coupling visible from the side that would break it.

Stale base. compare/develop...95616d16f → diverged, ahead 4, behind 35. Given this PR changes how 64 of 67 sources are scored, I would want the suite green against current develop before it lands rather than against a base 35 commits old.

Verified good

• The backwards walk anchors at the lane rather than the marker, with the reason stated (the lane itself sits between the last label and the marker, so anchoring at the marker would break the walk immediately) — that is exactly the trap, and calling it out in a comment is the right call.
• body.slice(record.end, start).trim().length !== 0 as the contiguity test is the load-bearing line and it is correct: whitespace-only gaps continue, anything else terminates.
• if (body.slice(markerRecord.end).trim()) return "marker must be the final source content" keeps the terminal requirement genuinely terminal, so the new scoping cannot be exploited by appending content after the marker.
• Both the template-checklist case and the shipped-template case are pinned by tests, not just asserted in the description. That is the difference between fixing #17610 and re-breaking it in three weeks.

Caveat: static review plus reads of develop at 64942cd44461ecc24b3ca1421de74900906e9506. The repository contract requires an isolated disposable sandbox to execute an untrusted head, which I do not have, so I did not run the suite — execution proof is blocked, not skipped. The stacked-footer trace above is read from the loop and ATTRIBUTION_LABEL_PATTERN, and I would want it confirmed by the test I suggested before anyone acts on it.

Thanks — this is a careful read, and it moved the PR even though the blocking trace doesn't land. New head 0b20894cac63d22a7e4d2acd8a2bb742e293be58, rebased onto current develop (was 35 behind).

The stacked-footer case is caught — by the rule one level up, not by the marker count

I ran your exact fixture against the real validator on this branch before changing anything:

AI provider/model: … / Client / agent tooling: … / Contribution skill revision: … / Attribution status: …
— [lane-one]
AI provider/model: … / Client / agent tooling: … / Contribution skill revision: … / Attribution status: …
— [lane-two]
<!-- eliza-computer-attribution:v1 {…} -->

→ invalidMarkers: [{ reason: "marker requires exactly one terminal lane signature" }]
→ declarations: no machine-marker declaration

The guard is markerFooterError's own earlier gate, ~20 lines above the terminalAttributionBlock call:

const laneSignatures = beforeMarker.filter((record) =>
  lanePattern.test(record.normalized),
);
if (laneSignatures.length !== 1 || …) {
  return "marker requires exactly one terminal lane signature";
}

A complete footer ends in a lane signature by definition, so two complete footers are always two lane signatures, and such a body never reaches the row counts at all. That check is unchanged by this PR — it appears in the diff as context, not as a change — so the protection did not "migrate" to the single-marker rule; it was never in the label-count check to begin with. Your backwards-walk trace is right about the walk, it just isn't the last line of defence.

That also settles your option 2: making the walk continue through an intervening lane signature would be unreachable code, since any body with two lane signatures is rejected before the walk runs. So I took option 1 — but the comment needed more than a softening.

What actually changed

88d173bf4 — the comment now names the enforcing rule per duplicate shape instead of claiming a blanket guarantee:

• adjacent duplicate rows collide inside the terminal block, caught by the row counts below it;
• two complete footers are rejected earlier by the one-terminal-lane-signature rule above it.

The #17610 rationale is unchanged, and no executable line moved in that commit.

New test still rejects two complete footers separated by different lane signatures, sitting directly beneath the adjacent-rows test so the two shapes read as siblings. It asserts the exact reason string and that no machine-marker declaration is emitted. I checked it is load-bearing rather than tautological: with the lane rule removed, the walk anchors at — [lane-two], stops at — [lane-one] (not a label), and yields a single well-formed footer whose fields match the marker — validation would succeed and both assertions flip. So your "right now nothing pins the behaviour for a lane-separated duplicate in either direction" was correct, and it is pinned now.

Your review surfaced a real one indirectly: the suite was red at the head you reviewed

The accepts the SHIPPED pull_request_template.md test was introduced by 95616d16f itself — the head under review — and it throws under this package's vitest config (environment: "jsdom"), where import.meta.url is not a file: URL for modules under src/**:

FAIL  src/lib/leaderboard.test.ts > accepts the SHIPPED pull_request_template.md with the footer appended (#17610)
TypeError: The URL must be of scheme file
 ❯ src/lib/leaderboard.test.ts:363:22

I reproduced that verbatim on this branch by restoring the old line, and nothing between 95616d16f and current develop touches this package's vitest setup, so bun run --cwd packages/eliza-computer test was failing 1 of 163 at the head under review. Fixed in 0b20894ca by resolving the fixture from process.cwd(), which is where both invocation paths already put us (.github/workflows/eliza-computer.yml runs bun run --cwd packages/eliza-computer test, and the aggregate runner sets cwd to the package dir). Worth knowing for anyone else adding a fixture here: scripts/** tests in this same package use fileURLToPath(import.meta.url) and are fine — the split is the transform, not the runner.

Suite is now 163/163 green against current develop (161 at your head + 1 from develop's #17615 + this PR's new test).

Non-blocking, answered

Template coupling. I'd rather leave the enforcement where it is than add a comment: the shipped-template test reads .github/pull_request_template.md from disk, so a template edit that puts checklist rows adjacent to the appended footer fails that test in CI — the coupling already fails from the side that would break it, which is stronger than a note asking someone not to. Happy to add the note as well if you still want the signpost.

Skill revision / Contribution skill revision both matching. Agreed it's a sharp edge, and it is deliberate for the reason you name. It is also exactly what the shipped-template test pins, so it can't drift silently.

Status note — the subject of this PR moved repositories, and the fix has followed it.

The refactor sweeps deleted packages/eliza-computer from this monorepo (commit a7b2007ab); the scoring hub now lives in the standalone elizaOS/army repository, which was split on 2026-08-02 — before this PR's fix existed. The deployed validator therefore still carries the template-footer collision this PR closes (verified today: src/lib/leaderboard.ts:1047 in elizaOS/army counts footer rows body-wide, no terminalAttributionBlock).

The fix is ported there as SlopDotCash/slopdotcash#5 — identical semantics, full 56-test suite green including the shipped-template red/green case, one path adapted to the split layout.

This PR's branch modifies files that no longer exist on develop, so it cannot merge as-is. Maintainers' call on disposition: close in favor of SlopDotCash/slopdotcash#5 (my suggestion), or advise if you'd rather it re-target somehow. #17610 remains the canonical defect record either way; its acceptance criteria are all satisfied by the ported PR, with the pr-evidence.mjs composition half already merged into this repo's history via the earlier commits.

Approving — the requested change is delivered, and the scope question resolved itself.

The validator half of the original PR is gone: packages/eliza-computer was deleted from the monorepo in a7b2007ab, and this head is a merge that accepts that retirement. So the net diff against today's develop is exactly two files — scripts/pr-evidence.mjs (+99) and scripts/pr-evidence.test.mjs (+147) — and git merge-tree is conflict-free.

That remaining half is precisely what the CHANGES_REQUESTED asked for ("implement the footer-aware insertion plus patchRow/patchEvidenceHead marker-finality tests here"), and it is still needed: scripts/pr-evidence.mjs:338 and :361 on develop still append after the body's terminal content, while packages/skills/skills/contribute-to-eliza/SKILL.md:56-58 instructs every contributor to append the eliza-computer-attribution:v1 footer after the PR template. The new LANE_SIGNATURE_PATTERN is byte-identical to the repo's own lane regex at scripts/check-agent-comment-attribution.mjs:442, so the footer grammar it recognizes is not invented.

Gate is green with no failing checks. Merging.

Three things worth knowing, none blocking, mostly about how much this actually buys:

1. Narrow practical reach today. The shipped .github/pull_request_template.md carries <!-- evidence-head:… --> and every <!-- evidence-row:* --> marker, so both patched fallback branches are unreachable for any template-derived body. The in-repo PR-body validator (scripts/check-pr-agent-attribution.mjs:12-14) uses a different marker (contribution-attribution:v1) with no finality rule, so the finality rule survives only for comments/issues via check-agent-comment-attribution.mjs:465. The main beneficiary is the out-of-repo elizaOS/army scorer.
2. Incomplete label coverage. ATTRIBUTION_LABEL_PATTERN recognizes only AI provider/model, Client / agent tooling, Contribution skill revision, Skill revision, Attribution status. The repo's own grammar at check-agent-comment-attribution.mjs:14-15 also accepts AI assistance: yes, Models used: and Model(s) used:. For a footer written with those spellings the backward walk stops immediately, footerStart collapses to the lane-signature line, and the fresh marker gets inserted between the label rows and the lane signature — splitting the block, which is the invalidation this PR exists to prevent. No regression versus today, but worth closing.
3. Second source of truth. The simplified footer parser is a deliberate reimplementation with no shared module and no cross-check against check-agent-comment-attribution.mjs, so the two can drift silently. The comment says this is intentional; I would still rather see one exported matcher.

Also: findTrailingAttributionFooterStart requires the hidden marker, so a human-only footer (AI assistance: no - …, which check-agent-comment-attribution.mjs:17 requires to be terminal and which carries no marker) still returns null and gets appended after.
