(OAuth) is the right delegation model (like GSC) but a swamp: Redirect URI rejects ALL local forms (http/https/127.0.0.1 — user-tested); refresh tokens are ROTATED + single-use, self-described non-compliant with OAuth 2.0 → store rewrite every call, AND our parallel seo‖geo dispatch would race the rotation → `invalid_grant` + dead token; undocumented "Could not extract expected anti-forgery token" on refresh, unanswered on MS Q&A; docs contradict themselves on grant_type + token endpoint; no library.

+## BLK-018 — release-executor finish span blocked by permission classifier (human signal invisible to subagent) — 2026-07-20
+- **Friction**: v1.3.1 release — `SPAN: finish` dispatch denied at tool-permission layer: classifier flagged "Merge Without Review" (`gitflow.sh finish` in subagent transcript carries no explicit human merge signal). Executor correctly refused workaround, reported BLOCKED. v1.2.0/v1.3.0 same span passed → classifier behavior change, not skill regression.
+- **Real cause**: gitflow doctrine "finish only on explicit human signal" lives in DISPATCHER transcript (user ask + STEP 4 AskUserQuestion go); subagent transcript starts fresh → classifier sees consequential merge with zero authorization evidence. Structural: any human-gated action dispatched to a subagent loses its gate evidence.
+- **Solution** (workaround): dispatcher ran `gitflow.sh finish` + tag inline after its own human gate — where the signal is real. Release completed clean (main `648bc6e`, tag v1.3.1).
+- **Status**: open. Candidate fixes: (a) quote gate evidence verbatim in span prompt — untested vs classifier; (b) move finish+tag span permanently inline in /release-candidate — keeps prep span dispatched, costs the sonnet pin on ~5 mechanical commands, cheap; (c) permission rule allowing subagent `gitflow.sh finish` — weakens the guard, refused. Decide at next release.

 Audit (user ask "profile toggles externals both ways?"): ASYMMETRIC. Enable side OK — gstack on-demand from submodule when pack off (shared `skills-disabled/gstack__*` convention with toggle-external.sh, interoperable), externals restored from parked, magic delegated to toggle-external.

Skill comparison: same core doctrine (root-cause iron law, hypothesis loop, regression test, 3-strike stop, >5-files alert) but incompatible wrappers — investigate monolithic (same context investigates+fixes+verifies, ~1075-line SKILL.md w/ gstack preamble/telemetry/onboarding, capitalizes to `~/.gstack` learnings.jsonl framework never reads at session start); bugfix orchestrator (reflection inline, sonnet bugfixer executor, fresh gates — BDR-066, LRN-083). Composition rejected: skills superpose in context, don't compose — invoking investigate inside bugfix = two full workflows, two completion protocols, two memory systems loaded at once. Decision: CLAUDE.global.md routing line inverted — bugfix primary; investigate ONLY on explicit ask for gstack ecosystem (cross-project learnings, /freeze scope lock, long no-commit investigation).

+- **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).

LRN-030 (Opus 4.8 under-delegates → "Default to delegation… counters under-delegation") inverted by Opus 5 (delegates MORE readily, official guide) — the rule pushed the failure the model now has. Same class: explicit verify instructions → over-verification; conservative-reporting clauses → literal recall suppression; MUST/CRITICAL → over-triggering.
+- **Opus 5 traps found**: (a) Claude Code injects Opus-5-only anti-delegation prompt sections (heron_brook + subagent_steer_delegation, issue #80988; server-gated, no opt-out, absent from transcripts) — own prose stacks on top blindly; (b) NO model-default effort hold on Opus 5 — persisted effortLevel (xhigh, settings.json) silently carries over, against "start high, sweep low/medium"; run /effort sweep per model; (c) effort does NOT shorten visible output/deliverables — only prose length rules do (+30-40% docs).
+- **future application**: at every model-generation bump, grep config for trait-compensating language ("counters model tendency…", "default to X") and re-verify the premise; prefer WHEN-guidance (conditions where X pays) over directional nudges — survives inversions unchanged.

+# PLAN — Adapt claude-config for the Claude 5 family (Opus 5 focus)
+
+Date: 2026-07-30 · Branch (planned): feature/opus5-config-tuning (off develop)
+KIND: build-plan · Author: main-loop session (Fable 5)
+
+## 1. Context & evidence
+
+Opus 5 (`claude-opus-5`, released 2026-07-24) now backs every `model: opus`
+agent pin in this repo (analyzer, plan-challenger, seo/geo-analyzer,
+plugin-advisor — BDR-076/077) and any session the user switches to via
+`/model opus`. Its documented behavioral profile differs from Opus 4.8 in
+ways that make parts of this config counterproductive:
+
+- E1 **Over-delegation**: Opus 5 "delegates to subagents more readily than
+  prior models" (official prompting guide). Opus 4.8 had the OPPOSITE trait
+  (LRN-030), and `CLAUDE.global.md:43-47` was written to counter it
+  ("Counters model tendency to under-delegate"). The premise is inverted.
+- E2 **Anti-delegation already injected by the harness**: Claude Code
+  v2.1.219 server-gates an Opus-5-only prompt section (`heron_brook` +
+  `subagent_steer_delegation`, GitHub issue #80988) that says "Do not call
+  the AgentTool unless the user requested it" and "Subagents multiply cost
+  and time…". Stacking our own hard cap on top would triple-constrain;
+  keeping a pro-delegation nudge would fight the injection. Model-neutral
+  when-guidance is the stable middle.
+- E3 **Over-verification**: official guidance — "If your prompt contains
+  explicit verification instructions … remove them: instructions like these
+  cause over-verification on Claude Opus 5, and removing them reduces wasted
+  tokens with no loss in quality." Also true of per-prompt "double-check"
+  phrasing. Targets PROSE told to the model, not harness-level gates.
+- E4 **Scope expansion**: named Opus 5 regression ("can expand the scope of
+  a task, adding steps that weren't requested"). Anthropic ships a literal
+  counter-block; tested to reduce scope changes "to nearly zero".
+- E5 **Literal instruction following** (since 4.7, stronger now): aggressive
+  MUST/CRITICAL language over-triggers; conservative-reporting instructions
+  ("only report high-severity") measurably depress recall in review/challenge
+  harnesses.
+- E6 **Longer written deliverables**: files written to disk run ~30-40%
+  longer; `effort` does NOT control visible/deliverable length — only prose
+  instructions do.
+- E7 **Overconstraint costs reasoning**: Anthropic removed >80% of Claude
+  Code's system prompt for Claude-5-generation models "with no measurable
+  loss"; named mechanism = tokens burned resolving conflicting rules.
+- E8 **Hook false positive (today)**: `\bux\b` in
+  `hooks/design-toolchain-reminder.sh:47` fired on French prose ("changement
+  ux vu" — matches after apostrophe/slash/space); 2nd `ux` FP in the log,
+  both French. Continues the LRN-1005/1007 false-positive series. No test
+  row covers `\bui\b`/`\bux\b`.
+- E9 **Effort carry-over trap**: Opus 5 has no model-default effort hold in
+  Claude Code — a persisted `xhigh` (our `settings.json:333`) silently
+  carries onto Opus 5 sessions, against Anthropic's "start at high, sweep
+  low/medium" guidance for that model.
+
+## 2. Design decisions
+
+- D1 The global instruction layer must be MODEL-NEUTRAL across the Claude 5
+  family (sessions run Fable 5 by default; dispatched judgment agents run
+  Opus 5; executors Sonnet). Fixes therefore express WHEN-guidance and
+  outcome bars, not directional compensation for one model's trait.
+- D2 Harness-level quality gates (fresh blind verifier + security-auditor,
+  BDR-049/050; plan-challenge, BDR-075) are architecture, not model
+  self-check prompting. They stay. E3 applies only to prose that tells the
+  MODEL to verify its own work.
+- D3 Per BDR-021, the Security and Architecture-decisions sections of
+  CLAUDE.global.md stay verbatim (deliberate policy). No softening there.
+- D4 Registries are append-only: LRN-030 is not edited; a new LRN records
+  the trait inversion and points back to it.
+- D5 Deterministic backstops (gitflow pre-commit, Gitea protection,
+  permissions.deny, rtk pinning) are explicitly out of "more freedom" scope
+  — community reports show Opus 5 working AROUND soft controls, which argues
+  for keeping hard ones.
+
+## 3. Work items
+
+### W1 — CLAUDE.global.md: rewrite the delegation block (:43-47)
+Replace the 5-line block (incl. "Default to delegation for multi-file
+exploration. Counters model tendency to under-delegate.") with model-neutral
+when-guidance, same footprint (≤5 lines):
+
+```
+- Sub-agents: one task per sub-agent, main context stays clean.
+  Delegate genuinely independent, sizeable tracks (wide multi-file
+  exploration, parallel audits) — not work doable in a few tool
+  calls, and not self-verification (harness gates own that). Brief
+  precisely, then commit to the delegation — don't redo its work.
+```
+Rationale: E1+E2. No hard spawn cap in prose (harness already injects one on
+Opus 5; Fable benefits from delegation).
+
+### W2 — CLAUDE.global.md: reframe "After code changes" (:75-83)
+Keep the concrete quality bar; drop the proof-mandate/self-check phrasing
+(E3). Replace steps 2-4 with faithful-outcome reporting:
+
+```
+## After code changes
+1. Run tests, lint, build, type-check if available.
+2. Report outcomes faithfully: what passed, what wasn't run,
+   remaining risks, surviving deviations. Completion claims only
+   for verified work.

+
+### W3 — CLAUDE.global.md: add scope fence (Workflow section)
+Append (adapted from Anthropic's tested block, caveman-compressed, ~5 lines):
+
+```
+- Scope: deliver what was asked, at the scope intended. Routine
+  judgment calls → decide alone; materially different readings →
+  ask. Better approach spotted → say so in one line, still do the
+  task as asked. Finish the whole task; genuinely blocked → do the
+  rest, state plainly what's missing.
+```
+Rationale: E4. Complements existing "Scope changes to task — no unrelated
+edits" (line ~15) without contradicting it.
+
+### W4 — CLAUDE.global.md: add deliverable-length rule (Code style / Comments area)
+~2 lines:
+
+```
+- Written deliverables (docs, reports, .md): length matched to what
+  the task needs — no filler sections, no boilerplate summaries.
+```
+Rationale: E6. Registries already covered by caveman rule.
+
+### W5 — Line budget
+After W1-W4: expected ~309 lines. Hard check: `wc -l CLAUDE.global.md` ≤ 320
+(session-start.sh warning threshold at :202-213).
+
+### W6 — hooks/design-toolchain-reminder.sh: drop `\bui\b` and `\bux\b`
+- Remove the two 2-char alternatives from the pattern at :47. Keep
+  `ui/ux|ux/ui|ui kit` and all other tokens.
+- Add a dated header comment (3rd tightening pass, 2026-07-30, cites the
+  two French-prose `ux` FPs; series LRN-1005/1007).
+- Trade-off accepted: a bare "améliore l'ux" prompt with no other design
+  token goes quiet — the CLAUDE.global.md "Design work" section still
+  routes it (the hook is a belt, self-described soft nudge).
+- Update `lib/tests/design-toolchain-reminder.test.sh`: add 2 quiet rows
+  (the real FP prompt excerpt; a bare "l'ui" French sentence) — flip-tested
+  per LRN-096. Existing 9 must-fire rows unaffected (none uses ui/ux).
+
+### W7 — agents/plan-challenger.md: coverage-first reporting line
+Add one clause to the findings rules (add-only, no removal): uncertain or
+low-severity findings are REPORTED with an explicit confidence + severity
+tag rather than self-censored — severity filtering happens in the
+orchestrator's synthesis, not in the challenger. Rationale: E5 (literal
+Opus 5 + "manufactured concern is a failure" wording risks suppressing real
+low-confidence findings). Must not touch: verdict grammar, MANDATORY PROOF
+clause, blind-dispatch rules (test-locked in plan-challenger.test.sh).
+
+### W8 — Memory + docs capitalization (same branch, follows the work)
+- decisions.md: new BDR (config adapted for Claude 5 family — scope,
+  rationale, alternatives incl. "leave config as-is" and "hard spawn caps"
+  rejected).
+- learnings.md: new LRN — Opus 5 behavioral profile (over-delegation
+  inverts LRN-030's Opus 4.8 trait; over-verification; literal following;
+  no effort hold on Opus 5 in Claude Code; heron_brook/#80988 injection).
+- journal.md: one line.
+- CHANGELOG.md: entry under Unreleased.
+
+### W9 — Gates (before commit)
+- `shellcheck hooks/design-toolchain-reminder.sh` clean.
+- Manual flip-test of the hook: FP prompt → quiet; "redesign the navbar" →
+  fires.
+- `make test` full suite green (design-toolchain-reminder.test.sh,
+  plan-challenger.test.sh, model-routing.test.sh untouched-but-must-pass,
+  curated-config-guard, loops-light…).
+- `wc -l CLAUDE.global.md` ≤ 320.
+
+### W10 — Gitflow
+`bash ~/.claude/lib/gitflow.sh start feature opus5-config-tuning` off
+develop; atomic commits (hook+test / CLAUDE.global.md / agent / memory+docs);
+NO `gitflow finish` — merge only on explicit human signal.
+
+## 4. Explicitly NOT doing (considered, rejected)
+
+- N1 Touching lib/verify-secure-loop.md or the fresh-verifier/security
+  gates: harness architecture (BDR-049/050, D2), verifies SONNET executor
+  output — not Opus 5 self-check prose.
+- N2 Softening the Security / Architecture sections (BDR-021, D3).
+- N3 Editing the superpowers plugin's "1% chance → MUST invoke" language:
+  external upstream code; flagged as residual over-triggering risk in the
+  new LRN, revisit as its own decision if observed.
+- N4 Changing `settings.json` `effortLevel: "xhigh"`: user preference,
+  optimal for the Fable 5 session default; the Opus 5 carry-over trap (E9)
+  is documented in the LRN + surfaced to the user for a manual decision.
+- N5 De-prescribing seo-analyzer.md / geo-analyzer.md (1528/1106 lines,
+  heavy MUST density): separate project, backlog note in TODO.md.
+- N6 Removing or session-gating the design/ctx7 reminder hooks: soft
+  nudges, cheap, deliberately built; tightened only (W6).
+- N7 Any model pin change: `model: opus` pins now resolve to Opus 5 —
+  desired outcome, census (model-routing.test.sh) untouched.
+- N8 Committing settings.json for any reason (LRN-098/1049 /model-churn
+  trap): file is currently clean; keep it out of every commit.

+## 5bis. CHALLENGE SYNTHESIS (2026-07-30) — FINAL amendments (v2)
+
+Verdicts: correctness CONCERNS(4) · robustness FATAL(5, 1 BLOCKER) ·
+simplicity CONCERNS(4). Every fix below is the challenger's own named FIX,
+adopted as written. No re-challenge pass: scope narrowed, no new dependency;
+W0 is an execution-time safety procedure, not a new config mechanism.
+
+- **W0 (NEW — robustness BLOCKER)**: all edited surfaces are symlink-deployed
+  LIVE (~/.claude/CLAUDE.md, hooks/, agents/ → this repo); edits take effect
+  machine-wide at save time, before any W9 gate. Mitigations:
+  (a) `gitflow start` BEFORE any live-file edit; never checkout develop
+  mid-work; (b) hook regex change validated on a SCRATCH copy first
+  (bash -n + shellcheck + pattern replay), then written to the live file in
+  ONE atomic Edit; (c) named reverts: `git show develop:<file> > <file>`;
+  escape hatch = remove the hook registration block from settings.json.
+- **W1 v2** (robustness#3, correctness#2): replacement text carves out the
+  mandated gates explicitly and scopes "don't redo":
+  "Skill-mandated gates (fresh verifier/security/challenge) always dispatch
+  as written. Don't redo delegated work by hand — failed gates re-dispatch
+  fresh executors instead."
+- **W2 v2** (simplicity#2): minimal diff — delete ONLY the line
+  `Bar: "would staff engineer approve?"`. Steps 1-4 + capitalize step stay.
+- **W3 v2** (simplicity#1, robustness#4): no new bullet. Fold the only new
+  clause into the existing Deviations bullet: "Finish the whole task:
+  blocked on an independent sub-part → do the rest, state what's missing.
+  Gone WRONG → still STOP, re-plan." (net +2 lines, no conflict with :53).
+- **W4**: unchanged (+2 lines). Budget v2: 304 +1 −1 +2 +2 = 308 ≤ 320.
+- **W6 v2** (all lenses): drop `\bux\b` ONLY — keep `\bui\b` (zero evidenced
+  FP; one logged true positive). Accepted trade-off: the 2026-07-21 "ameliore
+  le tutoriel…gamifier" ux row (plausible TP) goes quiet; CLAUDE.global.md
+  design-routing section remains the router. Header comment notes the log
+  records `head -1` only → per-token FP rate not fully derivable. Tests:
+  quiet row = synthetic "changement ux vu…" (verified matches pre-change →
+  flips); must-fire row = "revois l'ui du panneau admin" (locks `\bui\b`;
+  apostrophe escaped correctly, doubles as JSON-path control per
+  robustness#7). No log-excerpt rows (vacuous — 100-char truncation).
+- **W7 v2** (all lenses): in-place reword of the `:82-83` sentence (NOT
+  test-locked; plan v1 misstated that) instead of an add-only clause:
+  "No invention — ungrounded is noise. Silently dropping a grounded doubt is
+  equally a failure: file it as `[MINOR]` with the uncertainty stated in
+  `WHY:`. Nothing real at all → `SOLID` with `FINDINGS: none`."
+  OUTPUT grammar byte-identical; no confidence axis; no consumer change.
+  Census: add `has "$A" "grounded doubt"` row to plan-challenger.test.sh in
+  the same commit.
+- **W9 v2**: adds the W0 scratch-validation step; rest unchanged.
+- **W10 v2**: branch creation moves FIRST in execution order.
+
+## 5. Constraints for challengers
+
+- Registries append-only; curation only via /prune-memory.
+- Census tests lock behavior: any hook/agent edit must land with its test
+  update in the same commit; `make test` must stay green.
+- CLAUDE.global.md ≤ 320 lines (runtime warning threshold).
+- BDR-021: Security + Architecture sections verbatim.
+- Gitflow: feature branch off develop, no merge without human signal.
+- The global file serves ALL models (Fable sessions, Opus 5 dispatches,
+  Sonnet executors read skill/agent prompts instead) — no Opus-5-only
+  wording in CLAUDE.global.md.

 ## [Unreleased]
 
+### Changed
+- **Global instruction layer recalibrated for the Claude 5 family (BDR-081)** —
+  delegation block is now model-neutral when-guidance (the Opus 4.8
+  under-delegation counter inverted on Opus 5, which over-delegates and gets
+  an injected harness cap); "staff engineer" self-check bar dropped (Opus 5
+  over-verification trigger); finish-whole-task clause added to Deviations;
+  written-deliverable length rule added. 308/320 lines.
+- **design-toolchain hook** — dropped `\bux\b` (2 French-prose false
+  positives; 3rd tightening pass, series LRN-1005/1007); `\bui\b` kept and
+  locked by a must-fire test row.
+- **plan-challenger** — grounded-but-uncertain findings now file as `[MINOR]`
+  with the uncertainty stated, instead of being self-censored (Opus 5 follows
+  conservative-reporting clauses literally).
+
+## [1.4.0] — 2026-07-22
+
+### Added
+- **Transient planning artifacts auto-purged at feature-finish (BDR-065)** —
+  `gitflow finish` on a `feature`/`bugfix` branch now removes the run-time
+  superpowers artifacts (`docs/superpowers/{specs,plans}`) on the working
+  branch just before the directed merge, so `develop`'s tip lands clean while
+  the feature commits stay reachable as the archive (`git show <sha>:…`). This
+  automates the manual post-merge cleanup that BDR-065 had left as doctrine —
+  the step that slipped in 1.3.0 and needed a hand purge. Best-effort by
+  contract: a purge that finds nothing, meets uncommitted changes under those
+  paths, or fails to commit never aborts the finish (index/tree restored); opt
+  out with `GITFLOW_PURGE_TRANSIENT=0`. New `gitflow.sh purge-transient` verb.
+  `.claude/tasks/{contracts,plans}` are deliberately out of scope (durable,
+  versioned, referenced by the decision registry). Live in every project via
+  the `~/.claude/lib` symlink; covered by `lib/gitflow-test.sh` T17 (a–d).
+
+### Changed
+- **Bug routing inverted: `/bugfix` primary, `/investigate` explicit-only
+  (BDR-080)** — a bug / error / 500 now routes to `/bugfix` by default (the
+  full framework: gitflow, contract, fresh verifier + security gates,
+  registries). The gstack `/investigate` monolith — its own `~/.gstack`
+  memory, no gitflow or gates — is reserved for explicit requests
+  (cross-project learnings, `/freeze` scope lock, long investigation with no
+  immediate commit intent). Same core debugging doctrine, incompatible
+  wrappers; the default now favours the gated, integrated path.
