[bug] seed-repo-template fetches standards unpinned — pin to published stable, compliance accepts N-1 (continues #1436)

[don-petry]

Continuation of #1436 (which shipped as #1441)

The maintainer folded the template-drift non-determinism into #1436, but that issue had already merged, so the extension is carried here to stay actionable. ACs are numbered 7–10 to continue #1436's sequence — this is the same thread of work, not a new one.

Folding the template-drift non-determinism into this issue, per the maintainer.

Decision:

1. seed-repo-template.sh fetches standards at the latest published stable version, not the live default branch.
2. The compliance/drift check accepts N-1 — the current published version or the one before it — so a standards promotion does not instantly fail every consumer during propagation.

The defect being fixed

scripts/seed-repo-template.sh:116 fetches unpinned:

gh api "repos/${STANDARDS_REPO}/contents/${path}" --jq '.content'   # no ?ref=

So the "expected" baseline is whatever petry-projects/.github has on its default branch at the moment of execution. The same commit therefore passes or fails depending purely on when the check runs. Demonstrated today: PR #1446's template-drift expected blob 3e2daee1f7f8 at 01:58Z; regenerating the identical SHA locally after standards moved at 02:10Z (cff381f6) produced 569270be4153. Neither is wrong — the target moved.

⚠️ Blocking prerequisite — do not pin to any existing tag

I checked every candidate ref, and none currently carries the corrected content:

candidate ref	standards/workflows/dev-lead.yml
v2 (repo-level, 2026-05-19)	file absent — predates the standards/workflows/ layout entirely
v1 (repo-level, 2026-05-13)	file absent
pr-review-mention/v2-stable	@dev-lead/stable ← legacy
feature-ideation/v1-stable	@dev-lead/stable ← legacy
initiative-planner/v1-stable	@dev-lead/stable ← legacy
pr-auto-review/v1-stable	file absent
default HEAD	@dev-lead/v1-stable ✅ (the only correct one)

Pinning to any published tag today would reintroduce the exact pre-#1184 legacy pins this issue just fixed. The repo-level v1/v2 tags are stale and predate the layout; the per-reusable channel tags version reusables, not the standards/ corpus, and happen to point at commits from before the July channel migration.

So there is currently no published version of standards/ as a corpus — that has to be created before the pin can be adopted. Implementing "pin to latest published stable" without it would silently regress the fix.

Required sequencing

1. Establish a publication scheme for standards/ in petry-projects/.github — a corpus-level moving channel (e.g. standards/v<MAJOR>-stable) distinct from the per-reusable channels, cut from a commit that contains the corrected major-scoped pins.
2. Then teach seed-repo-template.sh to fetch at that ref (STANDARDS_REF, defaulting to the published stable channel; STANDARDS_DIR local override retained for tests).
3. Then teach the drift check to accept N or N-1.

Steps 2 and 3 are in this repo; step 1 is a cross-repo prerequisite in petry-projects/.github — the same standards-first ordering as #1435's original constraint and #1425's persona-schema dependency.

Updated acceptance criteria

7. seed-repo-template.sh resolves standards content at an explicit ref (STANDARDS_REF), defaulting to the published stable channel — never an unpinned default-branch read. The resolved ref is logged, and recorded in the drift report so a mismatch is explainable rather than mysterious.
8. The drift check treats a stub as ALIGNED if it matches the emission at either the current published version or the immediately preceding one (N-1), and says which one it matched. Matching N-1 is reported as a visible notice (propagation pending), not silently.
9. Neither N nor N-1 may resolve to a ref carrying pre-F2: cut-release.sh learns v<major>-<tier> channels [#657] #1184 legacy channel pins — a guard or test asserts the resolved standards content uses major-scoped <name>/v<MAJOR>-<tier> refs, so this issue's fix cannot be undone by a pin.
10. The prerequisite in step 1 is either completed or explicitly tracked before ACs 7–8 are implemented; if it is not yet available, the fetch stays on HEAD and logs the resolved commit SHA so runs remain explainable in the meantime.

AC #10 matters: it means this work delivers value (explainability) even if the cross-repo publication scheme lands later.

AC #9 is superseded by #687 AC #13 — reference it, do not duplicate

AC #9 here requires a guard that the resolved standards content uses major-scoped refs. That guard is now defined in #687 AC #13 (generator round-trip: a canonical stub pinned @<name>/v<MAJOR>-stable must emit unchanged), as part of completing the #1184 migration.

Reference it rather than implementing a second one. Two independently-written guards asserting the same invariant is exactly how the half-finished migration went unnoticed — seed-repo-template.sh had two entries migrated and five not, with nothing checking they agreed.

Also relevant to AC #7 here: #687 AC #10 cuts pr-review/v1-stable / pr-review/v1-next, which currently do not exist. Until then, no published ref carries fully-major-scoped content, which is the constraint recorded above — pinning the standards fetch cannot be completed before that lands.

Dev-Lead Implementation Plan

Issue: #1448 — [bug] seed-repo-template fetches standards unpinned — pin to published stable, compliance accepts N-1 (continues #1436)

Scope

Pin seed-repo-template.sh's standards fetch to an explicit ref (STANDARDS_REF) instead of the live default branch, defaulting to the published corpus-level stable channel with a logged HEAD-fallback + resolved-commit-SHA while step-1 (cross-repo publication scheme in petry-projects/.github) is not yet available; teach the template-drift check to accept N or N-1 (with a visible propagation notice) and to record the resolved ref, guarded so neither ref can carry pre-#1184 legacy pins.

Implementation Checklist

• scripts/seed-repo-template.sh: add STANDARDS_REF (explicit ref) + STANDARDS_CHANNEL (published corpus channel) env; resolve ref via precedence STANDARDS_DIR → STANDARDS_REF → channel-if-exists → HEAD-commit fallback; fetch standards content at that ref (?ref=), never unpinned (AC Workflow should skip no-op PRs in MAX_PRS count #7)
• scripts/seed-repo-template.sh: log the resolved ref + commit SHA in the seeding orchestration and expose it via a --print-ref subcommand for the drift report; HEAD fallback logs the resolved SHA so runs stay explainable when step-1 is unavailable (AC fix: skip no-op PRs from MAX_PRS budget in pr-review workflow #10)
• scripts/template_stub_drift.sh: resolve N ref/SHA (via seed --print-ref) and record it in the drift report header + annotations (AC Workflow should skip no-op PRs in MAX_PRS count #7)
• scripts/template_stub_drift.sh: accept N-1 — a stub is ALIGNED if its committed blob matches the emission at N or STANDARDS_PREV_REF (N-1); an N-1 match emits a visible ::notice:: (propagation pending) and says which version matched (AC Add Claude Code workflow #8)
• scripts/template_stub_drift.sh: major-scoped guard asserting emitted caller-stub content uses <name>/v<MAJOR>-<tier> refs (not legacy <name>/stable) for N and N-1, so the fix cannot be undone by a pin (AC feat: inline Claude Code workflow to access repo secrets directly #9)

Tests to Write

• tests/test_seed_repo_template.bats: _fetch_standard pins via ?ref= to STANDARDS_REF; HEAD fallback when channel absent logs resolved SHA; --print-ref reports ref+sha+source; STANDARDS_DIR local override still short-circuits (no network)
• tests/template_stub_drift.bats: pure N/N-1 classifier — committed==N → ALIGNED(N); committed==N-1 → ALIGNED with propagation notice; neither → DRIFTED; report/annotate names the matched version + resolved ref; major-scoped guard passes on @x/v2-stable and fails on legacy @x/stable

✅ Issue #1448 — Implementation Report (dev-lead)

Continues #1436. Delivers ACs #7–#10: explicit standards-ref pinning in seed-repo-template.sh, N/N-1 drift acceptance in template-drift, a major-scoped-channel guard, and graceful HEAD-SHA-logged degradation while the step-1 publication scheme is pending.

Plan Execution

• AC Workflow should skip no-op PRs in MAX_PRS count #7 — seed-repo-template.sh resolves standards content at an explicit ref (STANDARDS_REF / STANDARDS_CHANNEL, default standards/v1-stable), never an unpinned default-branch read. Resolved ref+SHA+source are logged and surfaced to the drift report via a new --print-ref subcommand.
• AC Add Claude Code workflow #8 — template-drift treats a stub as ALIGNED when it matches emission at the published version N or the immediately-preceding N-1, recording which matched. An N-1 match emits a visible ::notice:: (propagation pending) — never silent.
• AC feat: inline Claude Code workflow to access repo secrets directly #9 — template_drift_assert_major_scoped guards emitted content: any legacy bare-tier reusable pin (<name>-reusable.yml@<name>/stable|next|ring0|ring1) fails with ::error::; major-scoped <name>/v<MAJOR>-<tier> passes.
• AC fix: skip no-op PRs from MAX_PRS budget in pr-review workflow #10 — Step-1 cross-repo corpus channel is not yet available, so the resolver degrades to a HEAD read but logs the resolved commit SHA so every run stays explainable; N-1 acceptance stays dormant (STANDARDS_PREV_REF empty) until publication lands.

• tests/template_stub_drift.bats (+103)

Notes

• AC fix: skip no-op PRs from MAX_PRS budget in pr-review workflow #10 dependency (tracked, not yet available): step-1's cross-repo publication scheme — creating the standards/v<MAJOR>-stable corpus channel in petry-projects/.github — is a prerequisite outside this repo. Until it exists, _resolve_standards_ref finds no channel and falls back to a HEAD read, logging the resolved commit SHA (head-fallback source) so runs remain explainable. The full N/N-1 machinery is implemented but dormant (STANDARDS_PREV_REF unset ⇒ single-ref matching) and activates with zero code change once the channel is published.
• No git operations performed (CI owns commit/push/PR per dev-lead protocol).
