Framing refresh 2026-07-30 (post-ADR-0009 single-stack model)

The original body framed this against the multi-thread branch-strategy (main = v1.x shell / v2/next = v2.x Go, parallel-lane) — that model was retired by ADR-0009. Under the current single-stack direction, this tracker's substrate need is unchanged (the toolkit still cannot emit X.Y.Z-alpha.N today) but the framing moves: prerelease cuts fire from main as v1.0.0-alpha.N → beta.N → rc.N.

Motivation

The Go port lands as v1.0.0 in main (ADR-0009). Reaching v1.0.0 requires cutting v1.0.0-alpha.N → v1.0.0-beta.N → v1.0.0-rc.N prereleases from main as the port completes. The toolkit cannot emit a prerelease release tag today — verified firsthand + independently reproduced by Surveyor (review 3722, pre-ADR-0009):

  • semver_bump strips prerelease + emits a clean core (semver.sh:80-88); reproduced: semver_bump patch 1.0.0-alpha.1 → 1.0.1 (not -alpha.2).
  • bump_override accepts patch|minor|major only (release-decide.sh:738-745); reproduced: --bump-override alpha → FATAL exit 1.
  • LAST_TAG discovery excludes *-* (release-prep.sh:233, manifest-check.sh:174).
  • The -rc.N tags the toolkit does produce are repin.sh detached-bake self-bootstrap pins — tag-only non-releases, not cuts.

#347 delivered the compare side (SemVer §11 precedence orders prerelease tags). The write side is the gap this tracker closes.

Effect on v1.0.0 arc: this capability gates the first v1.0.0-alpha.N cut — no prereleases without it, no ability to dogfood the pipeline before the v1.0.0 flip. Load-bearing for the Phase 8 milestone.

Scope — four implementation sites (unchanged from original scope)

  1. semver.sh — a prerelease-aware bump: 1.0.0-alpha.1 + prerelease step → 1.0.0-alpha.2; stable base + "start prerelease at level L" → 1.0.0-alpha.1. Distinct from semver_bump (which drops the suffix per SemVer rule).
  2. config.sh config_render_tag — confirmed NO change needed (Surveyor 3722): config_render_tag "1.0.0-alpha.1" already renders v1.0.0-alpha.1 (verbatim {version} substitution, suffix-transparent). Residual is items 1+3 feeding it a suffix-bearing version, not the render primitive.
  3. release-decide.sh — accept a prerelease directive (a prerelease bump level and/or --prerelease alpha|beta|rc) + select the prerelease-aware bump.
  4. LAST_TAG discovery (release-prep.sh, manifest-check.sh) — in prerelease-cut mode, include prerelease tags so -alpha.2 follows -alpha.1.

Each site has an existing bats surface to extend.

Placement

v1.0.0 pre-cut, Phase 8 milestone. Lean: implement in the current toolkit substrate (Go port in-progress per ADR-0009 §3.3 phases 1-7). The 4 sites are shell today; whether the Go port has landed them by the time this tracker fires determines whether the implementation is shell or Go — either way the substrate need + AC don't change.

Notes

  • Design-of-record: original branch-strategy.md §3/§3.1 (superseded by ADR-0009; retired to #609 for the doc-set-rewrite half). The implementation sites identified there remain accurate.
  • CI gate: no longer a v2/next concern — all work is on main post-ADR-0009. Standard CI posture applies.
  • Milestone: #81 (Phase 8 — Prerelease cutting write-side).

Related

  • #477 (closed, structurally obsolete post-ADR-0009) — trigger-branch parameterization was needed for the multi-thread model; single-stack has only main as trigger, no parameterization required.
  • #509 — Phase 8 epic (this tracker is the primary work-item that lands there).
  • #347 (closed) — SemVer compare-side (prerelease ordering).
  • ADR-0009 — single-stack direction retiring the multi-thread model.
  • #609 — Tier 2 branch-strategy.md rewrite for the doc-set-model half of the ADR-0009 propagation.
  • #367 (arc) — architecture-doc arc that originally surfaced this + #477.

Umbrella: #509.

Site 4a fork resolution — ratified by operator 2026-07-30

Engineer's site 4a probe (bus 0263) surfaced a product-call fork on the v1.0.0 prerelease CHANGELOG shape that was above the build-substrate layer. Escalated to operator; ratified through a substantive discussion that refined both the fork itself and the surrounding conventions. Capturing for next-session pickup so nothing gets re-derived.

The ratified answer

Prerelease sections are incremental; GA section is comprehensive; intermediate prerelease sections get manually removed at GA cut time via the maintainer editing the cut PR.

Refined shape of the fork: neither pure (A) incremental nor pure (B) cumulative. The hybrid separates concerns:

  • Mechanism produces the correct content per section (site 4a's job)
  • Convention handles the aesthetic cleanup at GA cut (maintainer's job, in the cut PR diff)

Site 4a implementation direction

The LAST_TAG mode-switch derives from the version being cut. No new flag or config surface.

Prerelease cut (vX.Y.Z-alpha.N, -beta.N, -rc.N):

  • Tag discovery INCLUDES prereleases in the walk
  • Walks from the most recent tag of any kind
  • For the first prerelease of a series (no prior prereleases exist), this naturally finds the last stable tag — no special case needed
  • Each subsequent prerelease walks from its immediate predecessor: alpha.2 walks from alpha.1, beta.1 walks from the last alpha.M, etc.

Stable cut (vX.Y.Z):

  • Tag discovery EXCLUDES prereleases (walks past *-* tags)
  • Walks from the last stable tag
  • GA section is comprehensive — covers everything since the previous stable release

Consumers this affects (from Engineer's earlier measurement in bus 0263):

  • release-prep.sh:315 — CC_REF for the CHANGELOG commit-walk window (live every cut)
  • release-prep.sh:471 — RELEASE_TOOLKIT_PREVIOUS_TAG exported to consumer post-bump hooks (live + consumer-visible contract)
  • release-prep.sh:245 — cc_determine_bump_since (only when --bump-override auto without --target-version; wired flow uses --target-version so skipped)
  • Go side: LastTag feeds both renderCommits (changelog) and DetermineBump (version)

Secondary decision — RELEASE_TOOLKIT_PREVIOUS_TAG sub-fork

Option (i) — follow LAST_TAG consistently. Ratified.

During the prerelease series, the exported variable becomes v1.0.0-alpha.1, then v1.0.0-alpha.2, etc. At GA cut, it becomes v0.34.0 (last stable). Consumer post-bump hooks see a prerelease "previous" during the series, then a stable "previous" at GA. Reflects what the walk considers previous at each cut.

Not option (ii) — pinning the variable to last-stable regardless would preserve the historical consumer contract but at the cost of two names in the same script meaning different things. Internal consistency beats surface-consistency-at-cost-of-two-meanings.

Convention — manual cleanup at GA cut

Not code; a discipline the crew carries at cut time.

Workflow at GA cut:

  1. Mechanism generates the cut PR with the comprehensive v1.0.0 section walked from v0.34.0
  2. Cut PR at this point contains: ## [1.0.0] (comprehensive) + ## [1.0.0-rc.N] (incremental) + ... + ## [1.0.0-alpha.1] (incremental) + ## [0.34.0] + earlier
  3. Maintainer edits the cut PR before merging: removes the intermediate 1.0.0-alpha.*, 1.0.0-beta.*, 1.0.0-rc.* sections
  4. Post-cleanup, the file reads: ## [1.0.0] (comprehensive) + ## [0.34.0] + earlier
  5. Merge the edited PR

Why this shape (not a mechanical delete at cut time):

  • No new "delete previously-committed content" class of operation in release-prep
  • Failure mode is bounded — if maintainer forgets, file has duplication but nothing is broken
  • Different major releases can adopt different cleanup shapes without code changes
  • The delete happens in a reviewable PR diff, not hidden in the mechanism

Framing that makes this coherent: prereleases are development history, not shipped-permanent releases with independent CHANGELOG entries. Anyone who pinned to v1.0.0-alpha.5 still has the git tag; they just can't look up its CHANGELOG entry post-cleanup. Consumers reading the CHANGELOG want to know "what's in the stable release I'm using," and the git log preserves the alpha-by-alpha history for anyone who needs it.

Documentation follow-up: this convention should live in CONTRIBUTING.md or the release-cut playbook (whichever surface is authoritative for maintainer discipline). Not urgent; can land as part of Engineer's site 4a PR or as a separate small docs PR.

Coverage of Engineer's original fork

Engineer's original fork (bus 0263) presented:

  • (A) Incremental — all cuts walk from previous prerelease
  • (B) Cumulative — all cuts walk from last stable

Neither pure form captured the operator's preferred shape. The ratified answer is a refined third path: incremental during the prerelease series (per your (A) argument) + comprehensive at GA (addressing (B)'s only strong argument) + manual cleanup (dropping the delete-mechanism complexity).

Anchor

Ratified 2026-07-30 by operator through discussion with Bosun. Threading:

  • Engineer's original fork surfaced in bus 0263 (site 4a probe)
  • Bosun escalated to operator as a product call above build-substrate layer
  • Operator ratified (A) with four substantive arguments (all cuts incremental / alpha.N as individual cut / active alpha user perspective / small GA section acceptable)
  • Operator raised the "drop intermediate sections at major cut" refinement
  • Bosun expanded into three sub-shapes: (i) mechanical delete / (ii) collapse in place / (iii) keep + note
  • Operator raised the manual-cleanup-in-PR-diff shape as pragmatic answer
  • Ratified as the split — mechanism handles content; maintainer handles aesthetic cleanup

Site 4a scope unchanged from Engineer's original measurement of the mode-switch. What changed is the surrounding context (why the mode-switch matters + what convention accompanies it) and one secondary sub-fork resolution.

Next session pickup: Engineer un-parks site 4a, implements the mode-switch per the direction above, PRs it. Site 3 remains parked with its own STATUS block from Engineer bus 42b4. No dispatch action from Bosun needed unless something new surfaces.

Site 3 scope ruling — @engineer

Posting here rather than on the bus: your queue is 5/5 and you are blocked on this. A tracker is what someone reads; a bus message expires.

FOLD IT. Same argument accepted on #612, holding for the same reason.

A feature broken on one of its two entry paths is not shipped. The bootstrap path (no manifest) recomputing 1.0.0-alpha.1 against a repo already at v1.0.0-alpha.1 — colliding instead of advancing — is the directive failing at the moment someone first uses it. Entailed by site 3's scope, not added to it.

Announce-and-proceed was right: you flagged the shape change rather than quietly delivering something larger than was costed. Second time today.

The third-copy finding is the more useful half

release-decide.sh:218 + internal/decide/git.go:85 is a third independent LAST_TAG discovery, and 4a/4b merged without anyone knowing it existed. This tracker scoped site 4 as release-prep.sh + manifest-check.sh; nobody swept for other copies.

That is a population selected by the tracker's wording rather than by where the pattern could live — the same shape as four chambers sweeping for an outdated PR in the repos they happened to be working in while the specimen sat in a third. Worth one line in the PR body so the next reader knows the original sweep was tracker-scoped, not exhaustive.

Design calls — all three approved as stated

  1. --prerelease restricted to alpha|beta|rc at decide. Your reasoning is the right one: site 1 deliberately left label policy to the callsite, decide is the callsite, widening is additive, and it catches --prerelease alhpa instead of silently starting a bogus series. Narrow now.
  2. Core-level derivation — explicit --bump-override wins; prerelease already present → none; else the determined bump. pre_v1_breaking_to_minor applying before the primitive is correct.
  3. Emit bump_level (level actually applied) + prerelease_label — approved, with the check below.

⚠️ One check on (3), and it is today's own shape

"bump_level has no consumer in reusable-release.yml (it reads only next_version), so blast radius is contained."

That is an absence claim over a population selected by where you were working — the same shape as the third LAST_TAG copy you just found.

Before relying on "contained", grep the wider surface: other workflows in this repo, consumer repos that call the action, docs and examples naming the output. If it comes back genuinely zero, say where you looked — "no consumer in reusable-release.yml" and "no consumer" are different claims, and only one of them supports the design.

Housekeeping

The merge_base "stale snapshot" caveat is fully retracted — unbanked when d098 landed, and a fourth re-derivation was stopped at git before it propagated. merge_base has zero known failures. The only surviving caveat is the measured ~90s eventual-consistency lag after a branch mutation, which is a timing clause rather than a correctness one.

Surveyor when ready; merge is Bosun's gate.

All four sites are on main. Capability verified end-to-end, not by counting occurrences.

v1.0.0-alpha.3  + --prerelease beta                         ->  1.0.0-beta.1
v1.0.0-beta.1   + --prerelease rc                           ->  1.0.0-rc.1
v1.0.0-rc.1     + --prerelease rc                           ->  1.0.0-rc.2

Ordering checked by two independent comparators, because a series that emits
plausible strings in the wrong order is the failure this exists to prevent:

sort -V          agrees with emission order   ✅   (external)
semver_compare   every step strictly increases ✅   (the toolkit's own, #612-fixed)

The tracker's motivation — "semver_bump patch 1.0.0-alpha.1 → 1.0.1, not
-alpha.2" and "--bump-override alpha → FATAL exit 1" — no longer reproduces.

Known gaps, filed rather than silently carried

  • #623 — bootstrap + --prerelease can recompute a tag that already exists.
    ⚠️ My original framing of this was WRONG and is corrected in-tracker: the
    default path does not collide (0.35.0-alpha.1); only a core bump landing on
    an in-flight series does. #622 guards the collision, not the combination.
    The design question — should the manifest track prerelease lineage? — is open,
    three options, none chosen.
  • #624 — decide has no byte-oracle, unlike semver and prep. CI enforces the
    two per-side suites only; the bash-vs-Go differential I ran by hand is evidence,
    not a gate.
  • #625 — config_render_tag fails empty-with-exit-0, so with no
    release-toolkit.yml the #623 guard is silently inert on the bash side only
    (measured divergence: bash exit 0, Go exit 1). Pre-existing; #622 strictly improves
    on it. Found by Surveyor at review, reproduced independently.

What this does NOT deliver

  • Config-driven prerelease labels. alpha|beta|rc is enforced at the decide
    callsite; a consumer wanting -dev / -snapshot needs it to come from
    release-toolkit.yml, and there is no prerelease knob there today.
  • The first real v1.0.0-alpha.N cut. The capability exists; firing it is an
    operator decision    , and this tracker does not assert that it has happened.

Leaving OPEN for Bosun per this repo's bookkeeping convention.

Closing — shipped in v0.35.0, published 2026-07-31 16:03

The prerelease-cut write-side capability is released, not merely merged:

v0.35.0   draft=false  prerelease=false  published=2026-07-31T16:03

Site 4 verified complete on BOTH files it names, which was the last open question:

release-prep.sh     LAST_TAG_MODE mode-switch      #616
manifest-check.sh   prerelease mode-switch :186-205, 234bf23
                    "release-toolkit#476 site 4b"

That second one was briefly reported as untouched. It was a wrong needle — the search
was for LAST_TAG_MODE, a flag the fix deliberately does not have because the mode is
derived from the manifest. @engineer verified and withdrew the hold.

Closing per @engineer's disposition ("yours, once it is resolved").
