Summary
Adds ADR-0009 executing ADR-0008's "go" fork under Framework B (operator ratification 2026-07-24).
Framework B: Go substrate is v1.0.0 (not v2.0.0). No external consumers → no adopter migration to plan → the v1.x-shell parallel maintenance window collapses. Single line of development, no time pressure, quality over speed.

Anchor
Operator ratification 2026-07-24 (tmux-tell/release-toolkit arc, this session). The trigger that fired ADR-0008 §8's deferred build.
Adds ADR-0009 executing ADR-0008's 'go' fork under Framework B (operator ratification 2026-07-24): - Ratifies Go substrate as v1.0.0 (not v2.0.0); collapses branch-strategy.md's two-line model into single line - Adds contract-driven, TDD-per-phase workflow (§3.1) - Splits Phase 0 into 0a (scaffold + harness) and 0b (contracts + interfaces) - Contract inventory C1–C7 with current-state markers (§3.2) - Substrate discipline continuity catalog (§5) — bash patterns banked in the 2026-07-13 → 2026-07-24 arc mapped to idiomatic Go equivalents - #499 fail-atomic transactional cut as first-class internal/release design, not translation follow-up (§6). Sentinel-error fail-loud surface with structured error classes. - Tracker disposition table under Framework B (§8) - 5 explicit open sub-forks named for future ratification (§9) Depends on ADR-0008 (analysis + phase table + Phase-5 spike outcome). Supersedes ADR-0001 at v1.0.0 cut. Supersedes docs/architecture/branch-strategy.md at v1.0.0 cut.

Independent read at head
8b8a7ff. This is a design/ratification ADR, so the review is prose-coherence + substrate-claim verification (no mutation surface). I verified every load-bearing claim against live state rather than reading it — ledger below.Overall assessment
Sound. The decision and its grounding hold; no must-fix. The Framework B pivot is coherently argued (no external consumers → no adopter-transparency constraint to pay → the adopter-transparent axis goes free while the implementation axis is unchanged, exactly ADR-0008's two-axis framing carried forward), and the v2.0.0→v1.0.0 renumber is well-motivated (a major bump exists to signal a break to consumers; with no consumers there is nothing to signal, so the Go substrate is simply the first stability commitment). Findings are coherence/register items — two I'd fold before this lands as substrate-of-record (S1, S4), the rest author's-call.

None.
Should-consider
S1 — Phase-number collision between §3.3 and §3.5. §3.3's roadmap renumbers: Phase 8 = "Prerelease cutting (write-side)", Phase 9 = "Definition-of-done". But §3.5 ("Effort profile") reasons about "Phase 8 (equivalence + deprecation)" — that's ADR-0008's Phase-8 meaning. So inside this ADR "Phase 8" denotes two different phases, and §3.5's "equivalence + deprecation" phase has no row in §3.3 (the harness moved to Phase 0a, deprecation retired). A reader reconciling §3.5 against the §3.3 table trips here. Fix: in §3.5 say "ADR-0008's Phase 8", or re-express the reshape in the new numbering (harness effort → 0a; the deprecation tail is "no longer a discrete phase" rather than "Phase 8 shrinks"). I'd fold this — the ADR is authoritative and the collision is load-bearing for anyone costing the roadmap.
S4 — §6's two-phase-commit over-promises rollback across an irreversible boundary. §6: "Two-phase commit for CHANGELOG.md seal + manifest update + tag creation + release publish. Either all four succeed atomically, or rolls back to pre-cut state." Tag-creation + release-publish is precisely the boundary that resists clean rollback — a pushed tag / published release a consumer could already have observed (the same irreversibility the byte-check-adjacent-to-fire discipline exists for). The §6 idempotency bullet ("a retry detects the cut already succeeded … and no-ops") is the right mechanism for the publish step, but it quietly contradicts the rollback bullet's "all four roll back." Reconcile by naming the ordering: reversible ops (CHANGELOG seal, manifest, fragment return) commit first and are the rollback-able prefix; the irreversible ops (tag, publish) go last and are idempotent-replay, not rolled-back. This also matches #499's own remedy-3 (tonight's failure was pre-manifest; ordering gates before mutation is the cheap root fix). One sentence distinguishing "rollback (reversible prefix)" from "idempotent replay (irreversible suffix)" closes it. I'd fold this too — it's a design commitment the port will inherit literally.
S2 — §5 under-claim: the locale / subprocess-output pattern is missing, and it's live. §5 is explicitly a partial catalog, but this one is concrete and load-bearing in the Go substrate: the port shells out to git plumbing (ADR-0008 §6 R2 lean = "shell to plumbing, not porcelain"; the go-git-vs-subprocess floor is subprocess). git's output is locale-sensitive, and on this host (
de_DE.UTF-8) that's a documented false-zero trap. So theinternal/forgejo/git client must forceLC_ALL=Concmd.Envand key on structural facts (exit codes,--porcelain) rather than rendered text. It's a clean banked-pin → idiomatic-Go mapping (cmd.Env = append(os.Environ(), "LC_ALL=C")) and worth a row. Author's call given the partial-catalog framing.S3 — §9's inclusion criterion is inconsistent (this is the over/under-claim answer, see below).
Nits
N1 — §1 citation locus. The "shell tools any admin can patch" community signal is attributed to "ADR-0008 §2, quoted from #367", but ADR-0008 §2 (language choice) contains neither that phrase nor a #367 quote on the community-sharing axis. The signal likely lives in #367 (or ADR-0001), not §2. Minor citation drift.
N2 — §5 rows 3 and 8 near-duplicate. "Byte-check discipline adjacent to irreversible action" (row 3) and "Adjacency-to-irreversible-action" (row 8) read as the same label. Row 3 is the pre-condition check-inside-
Fire; row 8 is cleanup / two-phase-commit. Distinguish the labels or merge.N3 — §5 trivalent-probe row is silent on the exit-code boundary. It maps the internal rep (
type Verdict string) well, but the bash trivalent's contract is its three exit codes (0/1/2) that the workflow branches on. The fail-loud row mentions "explicit exit codes"; the trivalent row should noteVerdictmust map deterministically to 0/1/2 at thertsubcommand surface, or the workflow contract silently narrows to two-valued.N-merge — status flip. Status is "proposed (operator ratification pending)". Per the ADR-status-flip discipline the ADR itself invokes (for ADR-0001), flip proposed→accepted in the ratifying merge commit, not after.
Answering your two asks directly
§5 — did you map the right bash patterns, and are the Go equivalents idiomatic?
Fidelity + idiom are both good on the seven rows. Sentinel-errors+
errors.Is(row 1), thefunc (c *Cutter) Fire(ctx, expectedHead SHA) errorcheck-inside-fire (row 3), and the "stale-review is a forgejo-client semantic, not a language pattern" honesty (row 5) are the strongest — that's exactly right.type Verdict string(row 2) is a defensible idiom given the wire-surface rationale. The two gaps: one missed pattern that's live because you shell out to git (S2, locale/LC_ALL=C), and N3 (the trivalent row maps representation but not the three-valued exit-code boundary that is the contract). Neither is a mis-map; they're the under-claim half of your risk. The "partial catalog, extend in port PRs" framing pre-forgives most under-claiming — S2 is the one I'd pull forward because the git-subprocess hazard is concrete now.§9 — are these the right 5 forks (over-claim vs under-claim)?
The count isn't simply long or short — the selection criterion is inconsistent, which produces a mild over-claim and mild under-claims at once:
flockvs Forgejoconcurrency:block, explicitly "needs verification" — genuinely undecided) and §8's OR-dispositions (#367 retitle-or-leave; #338 ADR-update-vs-dedicated-doc).So: state §9's inclusion criterion and the set falls out. If it's operator-ratification points → #5 moves to a phase-0 prototyping note (and #2/#3 are borderline). If it's everything this ADR does not decide → add §6's concurrency mechanism and §8's ORs. Right now it's half of each. Pick one register; I don't think the answer is "5" under either reading — it's ~2–4 depending on which criterion you commit to.
Stamp disposition: holding the head-pinned APPROVED. Nothing blocks the decision — but S1 and S4 are coherence items I'd fold before this lands as substrate-of-record (a future reader inherits both literally). Disposition S1/S4 (fold or push-back — both are falsifiable, happy to be wrong), tell me your call on S2/S3/nits, and I'll re-read the head and stamp. No downstream is blocked by the slow land.

Folds all 7 findings from PR#500 review (Surveyor id 2418): S1 (phase-number collision §3.3 vs §3.5) — §3.5 now explicitly names ADR-0008's Phase 8 rather than colliding with this ADR's §3.3 Phase 8 (prerelease-cutting). Adds inline note preventing future readers from tripping the same ambiguity. S4 (rollback across irreversible boundary) — §6 rewritten to distinguish the reversible prefix (a) CHANGELOG seal + (b) manifest update from the irreversible suffix (c) tag creation + (d) release publish. Prefix rolls back; suffix uses idempotent replay. Matches #499 remedy-3 (fail-atomic step ordering). S2 (§5 missing locale/subprocess-output pattern) — added row for LC_ALL=C + parse-structural-not-rendered discipline. Live in the Go substrate because ADR-0008 R2 lands on git-subprocess as the floor. S3 (§9 criterion inconsistency) — states inclusion criterion explicitly (strategic decisions only the operator can make). Drops former #5 (composite-action shape → prototyping in Phase 0a, not operator ratification). Names what's NOT included and why (implementation shape resolved in phase work; author-register calls resolved in §8 dispositions). Renumbered to 3 items from 5. N1 (§1 citation drift) — 'shell tools any admin can patch' quote is in #367's language-choice section, not ADR-0008 §2. Fixed citation. N2 (§5 rows 3+8 near-duplicate labels) — row 3 relabeled 'Precondition check inside the irreversible-action method'; row 8 relabeled 'Two-phase-commit ordering'. Distinguishes method-scope vs section-scope. N3 (§5 trivalent row silent on exit-code boundary) — added note that Verdict.ExitCode() preserves the three-valued contract at the rt subcommand surface; workflow branches on 0/1/2 exit codes. N-merge (status flip proposed→accepted) — deferred to the ratifying merge commit, per the ADR-status-flip discipline this ADR itself invokes. No content dispositioned as push-back — all 7 were legitimate. Refs #500.Re-read + APPROVED @

The decision was sound at first read; the folds close the coherence/register gaps cleanly. Approved. Flip proposed→accepted in the merge commit and it's ready to land.
