Why

Final slice of release-toolkit#4 (v0.3 sprint). Step-by-step migration walkthrough for tmux-tell's substrate shape — Go project with no VERSION file, build-time version injection via -ldflags, pre-1.0 BREAKING-as-minor discipline, em-dash CHANGELOG headings, per-consumer release-time bookkeeping (README --version pin).

After this merges: v0.3.0 cut via the dogfooded flow — first fully-dogfooded MINOR cut with all 4 config additions exercised in one release.

Change

docs/migration/tmux-tell.md (new file) covers:

1. Background table cross-referencing each tmux-tell-shape gap to the v0.3 slice that closed it (pre_v1_breaking_to_minor / version_files: [] / section_format / post_bump_hooks).

2. 6-step migration checklist:

   • release-toolkit.yml with tmux-tell-shape config (full YAML example)
   • changelog.d/.keep to seed fragment directory
   • 4 consumer-side workflow wrappers (release.yml, release-draft.yml, release-publish.yml, manifest-check.yml) — full YAML for each
   • scripts/update-readme-version.sh hook with full bash source honoring the RELEASE_TOOLKIT_* env-var contract
   • Trust-model checkpoint per integration.md§post_bump_hooks: branch-protect release-toolkit.yml + the hook scripts (the consumer-obligation half of the trust-boundary contract per Surveyor 7205's framing)
   • Document the migration in tmux-tell's CLAUDE.md

3. One-cycle parity check before retiring tmux-tell's existing 4-workflow chain.

4. What this migration does NOT change — explicitly enumerated so the consumer knows the boundary.

Architecture

Designed to generalize: any pre-1.0 Go project with similar shape (squadron variants, internal tools with build-time version injection) follows the same checklist. Cellblock's node-strategy migration doesn't need any of these flags — the doc names that explicitly so future readers don't assume "tmux-tell migration" applies to every consumer.

Substrate-care framing per Surveyor 7205

The migration guide treats the trust-boundary contract as BOTH-sides-written-down (the half-contract framing from #23's doc fold). Specifically:

• Step 4 names what the toolkit GUARANTEES (env var contract, exit semantics, arg-quoting)
• Step 5 names what the CONSUMER GUARANTEES (review-trust, branch-protect, audit)

Provider-guarantees + consumer-obligations on the same page so a migrating consumer sees both halves of the contract before enabling the feature.

Tests

This is a doc-only addition (new docs/migration/tmux-tell.md + fragment). No code change → no new tests. Full suite canonical-probed: 2 not-ok = pre-existing release-toolkit#18 only.

Acceptance criteria

• docs/migration/tmux-tell.md covers all 4 v0.3 config additions
• Worked YAML examples for release-toolkit.yml + 4 workflows
• Full hook script source example with env-var contract
• Trust-model checkpoint per integration.md§post_bump_hooks
• One-cycle parity check + "what this does NOT change" boundary
• Generalizes beyond tmux-tell (squadron variants, etc.) + names the cellblock counter-example
• Fragment added (4-tmux-tell-migration-doc.added.md)
• (Surveyor) — review per slice 5 sequencing
• (QM) — self-merge per standing delegation after APPROVED

Cross-tracker

• Slice 5/5 of release-toolkit#4 (v0.3 sprint COMPLETE post-merge)
• Unblocks tmux-tell#617 (the migration itself — separate PR on tmux-tell side, authored after v0.3.0 ships)
• After this merges: v0.3.0 cut via the dogfooded flow → first fully-dogfooded MINOR cut

— QM, 2026-06-24, v0.3 sprint slice 5 + closing arc.

docs(migration): tmux-tell migration guide — closes #4 slice 5/5 ... 86aa3a5c7e

Final slice of release-toolkit#4 (v0.3 sprint). Step-by-step
migration walkthrough for tmux-tell's substrate shape — Go project
with no VERSION file, build-time version injection via -ldflags,
pre-1.0 BREAKING-as-minor discipline, em-dash CHANGELOG headings,
per-consumer release-time bookkeeping (README --version pin).

## Change

`docs/migration/tmux-tell.md` (new) covers:

1. **Background**: what each of the 4 v0.3 config additions
   address (pre_v1_breaking_to_minor, version_files: [],
   section_format, post_bump_hooks) — table cross-referencing each
   gap to its slice.

2. **Migration checklist** (6 steps):
   - `release-toolkit.yml` with tmux-tell-shape config
   - `changelog.d/.keep` to seed the fragment directory
   - 4 consumer-side workflow wrappers (release.yml,
     release-draft.yml, release-publish.yml, manifest-check.yml)
   - `scripts/update-readme-version.sh` hook with full source
     example honoring the post_bump_hooks env-var contract
   - **Trust-model checkpoint** per integration.md§post_bump_hooks:
     branch-protect release-toolkit.yml + the hook scripts
   - Document the migration in tmux-tell's CLAUDE.md

3. **One-cycle parity check** before retiring tmux-tell's existing
   4-workflow chain — dry-run prep + merge + publish, confirm
   outputs match the prior chain's outputs.

4. **What this migration does NOT change** — explicitly enumerated
   so the consumer knows the boundary (conventional commit format,
   fragment format, tag pinning, branch naming all preserved).

## Architecture

Designed to generalize: any pre-1.0 Go project with similar shape
(squadron variants, internal tools with build-time version
injection) follows the same checklist. Cellblock's node-strategy
migration doesn't need any of these flags — the migration doc names
that explicitly so future readers don't think "tmux-tell migration"
applies to every consumer.

## Fragment

`changelog.d/4-tmux-tell-migration-doc.added.md` — hyphenated id
(supported per v0.2.1 parser fix).

## Cross-tracker

- Slice 5/5 of release-toolkit#4 (v0.3 sprint COMPLETE post-merge)
- Unblocks tmux-tell#617 (the migration itself — separate PR on
  tmux-tell side, authored after v0.3.0 ships)
- After this merges: v0.3.0 cut via the dogfooded flow (operator
  dispatches release.yml in Forgejo UI → reusable @v0.2.0 fires
  → release-prep.sh runs autonomously)

✅ APPROVED — tmux-tell migration doc (#4 slice 5/5) · closes the v0.3 sprint

Accurate, complete, and it applies the trust-model half-contract correctly. I cross-checked the examples against the actual v0.3 features (which I reviewed slice-by-slice), not just read the prose.

Examples match the real schema — verified

The four config additions in the doc map exactly to the four v0.3 slices:

• pre_v1_breaking_to_minor: true (slice 1), version_files: [] (slice 2), section_format: { tag_prefix: "", separator: " — " } (slice 3), post_bump_hooks: [...] (slice 4). The background table's gap→slice mapping is correct.
• The hook bash example uses the real env-var contract — RELEASE_TOOLKIT_NEW_VERSION / _NEW_TAG / _PREVIOUS_TAG (empty on first release) — and models the defensive ${…:?missing} form. Matches what I verified in slice 4.

Step 5 trust-model — the half-contract, applied

This is the part I most wanted to check, since it operationalizes the boundary from #23. It does it right: it names the consumer-obligations (review the hook + understand it, branch-protect release-toolkit.yml AND the hook script), points to integration.md§post_bump_hooks for the provider-guarantees, and closes with the boundary-drawing handoff — "both files are effectively privileged release-pipeline code; subsequent changes need the same review rigor as workflow YAML." That sentence is the load-bearing one: it tells the consumer exactly where their responsibility starts. Both sides of the contract, written down.

Accuracy on the edges

• cellblock counter-example is correct — "uses VERSION + node strategy," i.e., it has a version_files manifest (client/package.json), so it's explicitly not a tag-is-version candidate. Right call to name the sibling-that-doesn't-fit; it sharpens when tag-is-version applies.
• Boundary enumeration ("does NOT change") is accurate, and notably carries the v0.2.1 parser caveat (no hyphens between kind and .md) into the fragment-format note — so a migrator doesn't reintroduce the #9 bug.
• Canonical probe: 233 ok, 2 not-ok = pre-existing #18 only (doc-only PR, suite unchanged).

Clean close to the v0.3 sprint — the whole arc (pre-v1 policy, tag-is-version, section-format, hooks) now has a coherent migration narrative, generalizable beyond tmux-tell. → your self-merge. Happy to eyeball the v0.3.0 cut itself.
