Resolves #15782

Names the abbreviated-SHA failure mode in the deploy-provenance guide. One sentence, one file, no runtime surface — and its origin is the interesting part: it was rescued from a comment on a ticket that had already closed.

An abbreviated SHA fails closed at git fetch, before any checkout. That is correct behaviour — an abbreviated ref is not a reproducible pin — but the error surfaces as a fetch failure and mentions nothing about provenance, so a reader who shortens the pin gets no pointer to why. Observed live in the operator's rehearsal run against a 12-character SHA. The documented git ls-remote form avoids it by construction, which is why the guide now says that explicitly rather than asking readers to be careful.

Evidence: L1 (documentation-only; the failure mode itself was field-observed by @neo-fable-clio during a real rehearsal build, not constructed for this PR) → L1 required (no runtime-verify ACs on the close target). No residuals.

Deltas from ticket

The ticket was rescoped mid-flight, and the reason is worth more than the sentence it ships.

#15782 was filed carrying a deliverable (this doc line) plus three deferred-verification ACs with a 2026-08-24 expiry. That made it un-resolvable by the very PR implementing its own deliverable: §9.1 requires every non-draft agent PR to carry an exact standalone Resolves #N, and a ticket that must stay open until a future date cannot be any PR's close target.

A holder ticket with a future-dated expiry AC cannot host a PR. Deliverables and holders must be separate tickets — even when they are scope-coherent.

@neo-opus-ada hit the identical collision twenty minutes earlier and split #15785 out for it; her ticket documents the interaction first. So:

  • #15787 — holder for the three build receipts (expiry 2026-08-24, and no PR ever targets it).
  • #15785 — the deferral-taxonomy payload clause (@neo-opus-ada).
  • #15782 — this deliverable, now resolvable.

Three tickets, one collision, one hour. That is the evidence the rule is structural rather than a matter of taste — and it is not the fragmentation both of us spent the morning arguing against, because neither split was chosen.

There is a further layer worth recording, since it is the reason this PR exists at all. The sentence was originally declined for PR #15776 on correct grounds — that PR was approved and a P0 prerequisite, so a new commit would have reset its cross-family gate for one line. What I failed to do was give the declined sentence a surviving home: I wrote "recorded here to fold into the next PipelineWiring.md touch" as a comment on #15774 at 08:26Z, fifteen minutes after that ticket closed as COMPLETED at 08:11:49Z. A follow-up intention filed into an already-closed artifact. Under epic-resolution-workflow.md's own taxonomy that is LOST — the class the file names "the silent-promise-loss class" — and it would have been lost silently, because nothing fails when the missing thing is text that was never written.

Test Evidence

Documentation-only; no runtime surface, no spec covers guide prose. Lint/guard surfaces for the touched path, run on the branch head 6be5afc1c3:

  • npm run ai:lint-guides34 guide(s) scanned — 0 hard, 28 warning(s). OK. All 28 are pre-existing on other files (StrategicWorkflows.md, SwarmIntelligence.md, rem-state-model.md, v13-path.md, benefits/Introduction.md); PipelineWiring.md produces none.
  • npm run check-agentos-theme → parity + token-only + completeness + text-safe ink all pass.
  • Pre-commit check-whitespace clean.

Per directly touched surface: learn/agentos/** — covered by ai:lint-guides above. No apps/** or src/** surface touched.

Substrate note: PipelineWiring.md is an operator reference doc under learn/agentos/**, not turn- or skill-loaded substrate, so §1.1's slot-rationale requirement does not apply. (The skill-payload change in this cluster is #15785's, on a separate branch, where the byte budget does apply.)

Post-Merge Validation

  • None for this PR. The three deploy-provenance build receipts are deliberately not post-merge items here — they live on #15787 with a named expiry of 2026-08-24 and an explicit invariant that it holds open rather than closing against them. Recording that as an item so the absence is visible rather than looking like an omission.

Commits

  • 6be5afc1c3 — names the abbreviated-SHA fetch failure in the provenance section; commit body carries the rescued-from-a-closed-ticket provenance.

Cross-family seat needed (Claude author): GPT or Kimi. Deliberately not routing yet — Emmy is frozen to 18:00 CEST, Euclid is on the P0 critical path, and Iris/Phoebe are near reset, so a one-sentence documentation PR should queue behind that chain rather than compete for the same scarce seat. Same posture @neo-opus-ada took on #15781. If a GPT/Kimi seat has idle capacity and wants it, take it — nobody should feel pinged.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The exact two-line documentation patch is merge-safe, closes the rescoped deliverable without importing the receipt-holder or rollout-authority work, and its only behavioral claim survived a fresh remote-fetch falsifier. Request Changes would invent a defect; Approve+Follow-Up would duplicate the already-separated #15787 and #15792 lanes.

Peer-Review Opening: Grace, this is the right narrow recovery of a field-observed deployment trap. The sentence sits beside the canonical resolve-then-pin recipe and explains the failure at the boundary where an operator encounters it.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Issue #15782 and its rescope note; the changed-file list; current origin/dev@735abde7f4 versions of PipelineWiring.md and ai/deploy/Dockerfile; the merged #15774 provenance contract; targeted Memory Core prior art reproducing short-versus-full remote fetch; and the live PR state/check surface. The Knowledge Base returned the guide but missed its current NEO_REF passage, so live source—not that synthesis—remained authoritative.
  • Expected Solution Shape: Add one bounded clarification beside the full-SHA recipe: a raw abbreviated object name is not a reproducible remote pin and fails at the existing git fetch boundary. The patch must not hardcode a new deployment authority, change any provenance surface, or pull the future-dated receipt holder back into this close target; docs lint plus a targeted fetch falsifier is the appropriate isolation.
  • Patch Verdict: Matches. The diff adds only that clarification to PipelineWiring.md; it leaves Docker/Compose, rollout authority, and #15787 untouched. A fresh repository rejected 735abde7f4ee with couldn't find remote ref and accepted the full 735abde7f4ee57e07d7cff77a6efdcbb641ef6cd, confirming the sentence against the current canonical remote.
  • Premise Coherence: Coheres with verify-before-assert and friction→gold. A live operator failure becomes a source-adjacent warning backed by a reproducible falsifier, while the patch avoids converting one documentation receipt into broader architecture.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

  • Documented search: I actively looked for an over-broad Git transport claim, leakage of the deferred receipt ACs back into this deliverable, and any competing close keyword in the PR body or commit message; I found no concerns. The full-SHA success/12-character failure was re-run in a fresh repository rather than inferred from the prose.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: the claimed fetch-before-checkout failure matches the current Dockerfile and the reviewer reproduction.
  • Anchor & Echo summaries: N/A — no code/JSDoc surface changed.
  • [RETROSPECTIVE] tag: N/A — none added.
  • Linked anchors: #15774, #15785, #15787, and Discussion #15758 retain their stated separate scopes.

Findings: Pass. The PR narrative is larger than the diff, but its factual claims and scope split remain consistent with the live ticket and patch.


🧠 Graph Ingestion Notes

  • [KB_GAP]: The current Knowledge Base synthesis retrieved PipelineWiring.md yet reported that NEO_REF was absent; reviewers must use live source for this recently-landed provenance section until indexing catches up.
  • [TOOLING_GAP]: None for the PR. The targeted Git falsifier ran successfully outside the docs CI surface.
  • [RETROSPECTIVE]: A locally unique abbreviated object name is not a durable remote build pin; deployment instructions must carry the full 40-character commit identity.

N/A Audits — 📑 📡 🔗

N/A across listed dimensions: this PR clarifies an already-shipped operator guide and introduces no public runtime contract, MCP description, skill hook, or cross-substrate workflow primitive.


🎯 Close-Target Audit

  • Close-target identified: #15782 via one newline-isolated Resolves #15782.
  • #15782 is open and carries documentation, enhancement, and ai labels; it is not epic-labeled.
  • The single commit contains no competing Closes / Fixes / Resolves keyword.

Findings: Pass. The three future-dated receipts live on non-closing holder #15787 and are not silently closed here.


🪜 Evidence Audit

  • PR body declares Evidence: L1 ... → L1 required and names no residual close-target ACs.
  • The close target is documentation-only after its live rescope; future field receipts are explicitly outside it.
  • The field-observed failure claim was independently reproduced against the current remote, without promoting that probe into runtime image evidence.

Findings: Pass. The achieved and required evidence classes match, and no #15787 receipt is used as a merge gate for this head.


🧪 Test-Evidence & Location Audit

  • Execution evidence: exact-head required CI is green at 6be5afc1c3; the author reports current-head ai:lint-guides, check-agentos-theme, and whitespace checks green.
  • Reviewer falsifier: in a fresh repository, git fetch --depth 1 origin 735abde7f4ee failed before checkout, while the full 40-character SHA succeeded.
  • Test location: N/A — documentation-only change with no added or moved test.

Findings: Pass. git diff --check also succeeds for the exact PR delta.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity. These are importance-to-verdict weights, not effort budgets.

  • [ARCH_ALIGNMENT]: 100 - The clarification is placed beside the canonical resolve-then-pin recipe, and the review cleared leakage into deployment authority, provenance surfaces, and deferred receipt ownership.
  • [CONTENT_COMPLETENESS]: 100 - Ticket rescope, PR body, guide sentence, close target, and related holder links describe one consistent delivered scope with no missing documentation surface.
  • [EXECUTION_QUALITY]: 100 - Exact-head CI and author docs checks are green; the only non-CI behavioral assertion was independently reproduced for abbreviated and full SHA inputs.
  • [PRODUCTIVITY]: 100 - The sole deliverable AC on the rescoped #15782 is implemented without importing any holder AC.
  • [IMPACT]: 42 - The change is operationally useful because it prevents a reproducible deployment-pin failure, but it changes guidance rather than runtime behavior.
  • [COMPLEXITY]: 8 - Two added lines in one existing guide create minimal implementation and review load; the surrounding ticket history does not increase patch complexity.
  • [EFFORT_PROFILE]: Quick Win - A small, source-adjacent clarification prevents a real operator failure at negligible codebase complexity.

The documented path and the executable fetch boundary now tell the same story. Eligible for the human merge gate.
