chore(memory): BDR-065 amendment (auto-purge coded) + LRN-138 + journal

BDR-065 delete-side now automated (lib/gitflow.sh _gitflow_purge_transient).
LRN-138: gitignore != delete for run-time artifacts read from disk — use
commit-during-run + auto-delete at the integration boundary. TODO checked,
journal line.

- **Why**: user call 2026-07-14 — registries already capture decisions; a stale plan describes a superseded intermediate state and misleads future readers; accumulation pollutes the repo. Precedent: gsc-crux cleanup (8a1fac0, 2026-07-10) did the same — this makes it law, not habit.
- **Alternatives rejected**: never-commit (gitignore docs/superpowers) — breaks mid-run: briefs, reviewers, other-machine checkouts need the files; superpowers brainstorming commits the spec by convention. Keep-forever — the drift + pollution complained about.
- **Reference**: project CLAUDE.md; cleanup commit this chore; precedent 8a1fac0. Linked [[BDR-064]], [[LRN-124]].
- **Amendment (2026-07-22)**: DELETE side now AUTOMATED — `lib/gitflow.sh` `_gitflow_purge_transient` at `gitflow finish` (feature/bugfix, pre-merge, on HEAD) git-rm's `docs/superpowers/{specs,plans}` + scoped commit → develop TIP clean, feature commits stay reachable (`git show <sha>:…` archive intact). Best-effort: NEVER aborts finish (nothing-tracked no-op / dirty-path skip / commit-fail index+tree restore). Opt-out `GITFLOW_PURGE_TRANSIENT=0`. Retires the manual chore that slipped (655e364). Universal via `~/.claude/lib`→repo symlink (ship-feature STEP 9 + init-project STEP 11 both finish through it). gitignore STILL rejected — unchanged: breaks superpowers' `git add` of the spec (silently skipped, no travel to SDD worktree). `.claude/tasks/{contracts,plans}` kept versioned (user call — durable, referenced by decisions.md). Tests: gitflow-test.sh T17 a-d. [[LRN-138]].

- Skill audit (user ask "pourquoi pas investigate dans bugfix ?") → same core doctrine, incompatible wrappers: investigate = monolithic gstack (own memory ~/.gstack, no gitflow/gates, ~1075-line preamble), bugfix = orchestrator (contract, fresh verifier+security gates, registries).

## LRN-138 — gitignore ≠ delete for run-time artifacts read from disk (2026-07-22)
- **pattern**: gitignore is the WRONG tool for an artifact a pipeline READS FROM DISK during a run — it blocks the commit but leaves the file (cleans nothing) AND breaks git-travel flows (superpowers commits the spec via `git add` so it reaches the SDD worktree; a gitignored path is silently skipped w/o `-f`). Right tool = commit-during-run + AUTO-DELETE at the integration boundary (`gitflow finish`, pre-merge, on the working branch → history keeps the archive, develop tip clean).
- **context**: user asked to gitignore transient planning artifacts (`docs/superpowers/{specs,plans}`, `.claude/tasks/{contracts,plans}`) to stop them merging. BDR-065 had already REJECTED gitignore for docs/superpowers on the git-travel ground; the real gap was the DELETE side never being coded (doctrine-only manual chore, slipped once — 655e364). Built `_gitflow_purge_transient`.
- **future application**: "don't merge transient X" → ask: does the run read X from disk? does X travel via git (worktree, foreign checkout)? Yes → auto-purge at finish, not gitignore. Scoped commit `-- <paths>` avoids sweeping a dirty index; `git diff --quiet HEAD -- paths` precheck makes `git rm` all-or-nothing safe; keep the purge best-effort so cleanup NEVER blocks a merge. Prove archive-reachability with `git log --full-history` / `git show <sha>:path` — plain `git log -- path` prunes the purged add-commit via history simplification (bit me writing T17).

# TODO
## 2026-07-22 — auto-purge transient superpowers artifacts at finish (feature/gitflow-auto-purge-transient)
User: transient planning artifacts (`docs/superpowers/{specs,plans}`) leak into
develop; BDR-065 "post-merge cleanup" is DOCTRINE ONLY (no code) — manual chore,
already missed once (655e364). Decision (user 2026-07-22, 2 recommended picks):
keep committed-during-run (SDD worktree + reviewers read them), AUTOMATE the
delete at `gitflow finish`. NO gitignore (would break superpowers' `git add` of
the spec → no travel to SDD worktree). `.claude/tasks/{contracts,plans}` stay
versioned (durable, referenced by decisions.md e.g. BDR-076). Universal via the
`~/.claude/lib` → repo `lib` symlink: every project's finish gets it.
- [x] lib/gitflow.sh: `_gitflow_purge_transient` (clean-precheck → git rm →
scoped commit `-- paths`; best-effort, NEVER aborts finish; opt-out
`GITFLOW_PURGE_TRANSIENT=0`) wired into finish `feature|bugfix` pre-merge;
`purge-transient` CLI verb.
- [x] lib/gitflow-test.sh T17 a/b/c/d (purge+recover-from-history via
--full-history+`git show`, no-op when absent, opt-out keeps, chore scope).
Also fixed 2 pre-existing SC2034 warnings (T16 gl_out/noleaks_out).
- [x] Gate: shellcheck lib/*.sh CLEAN + `make test` exit 0 (gitflow 106/0, full
suite green). Universal via ~/.claude/lib → repo lib symlink (verified).
- [x] CLAUDE.md §Transient planning artifacts: → "AUTO-PURGED by gitflow finish".
- [ ] Capitalize: BDR-065 amendment (delete side now automated) + LRN — pending user OK.
## 2026-07-20 — pending merge gates (reconcile)
- [x] merge feature/profile-managed-externals → develop (BDR-079 profile
symmetry + /doc clean pass: README/USAGE/ARCHITECTURE.md) — 37c79f0
