+# ANALYSIS: model-tiering v2 — Fable = orchestration + plan/solution reflection only; dispatched fleet tiered opus/sonnet/haiku by task complexity; split mixed-tier agents
+
+Produced by /analyze (main loop, Fable) + 4 subagent sweeps (2× agent-body
+classification, dispatch map, test-lock inventory), 2026-07-19. Facts verified
+against: model-routing.test.sh, challenge-plan.md, verify-secure-loop.md,
+model-gate.md, BDR-050/061/066/076, LRN-113/125/126 (read in full inline).
+Subagent-reported details not re-verified inline are marked (sub) — LRN-132
+applies: re-verify load-bearing ones before cutting code.
+
+## CONTEXT
+
+- Current state (branch `feature/opus-pin-audit-agents`, 2 commits, UNMERGED):
+  main loop = session model (Fable; model-gate blocks small models in 15
+  reflection skills). Dispatched pins: opus = analyzer, plan-challenger,
+  seo-analyzer, geo-analyzer, validator-analyzer (BDR-076); sonnet = 14
+  executors; haiku = status-reporter. Unpinned = interviewer,
+  client-handover-writer (inline-load only).
+- Two execution modes with OPPOSITE tier semantics: Agent() dispatch →
+  frontmatter pin applies; inline-load ("you become it") → pin INERT, runs on
+  session model. 20 inline-load sites exist.
+- Target policy (user directive): Fable does ONLY main-loop orchestration +
+  reflection on plan/solution. Everything dispatched runs opus (deep judgment)
+  / sonnet (standard execution) / haiku (mechanical) by ACTUAL task
+  complexity. Agents mixing classes get split. Skills adapted. Zero loss, zero
+  regression.
+
+## KEY COMPONENTS — per-agent verdict vs target
+
+### Fits, no change
+| agent | tier | note |
+|---|---|---|
+| plan-challenger | opus | coherent monolith; verdict grammar + PROOF load-bearing |
+| feater / bugfixer / hotfixer | sonnet | closed-plan executors; NEED-DECISION / BLOCKED valves |
+| security-auditor | sonnet | deterministic SAST gate; `SECURITY — VERDICT:` grammar |
+| scaffolder | sonnet (effort: high) | but see INERT-PIN below — never dispatched today |
+| status-reporter | haiku | exemplar mechanical |
+| client-handover-writer | none (inline orchestrator) | one haiku-able seam: STEP 1-2 git/context preflight |
+| interviewer | none (inline) | INTERACTIVE — asks user inline; a dispatched agent cannot ask (uniform ban). Structurally main-loop. |
+
+### Tier-down candidates (no split)
+| agent | current → candidate | evidence |
+|---|---|---|
+| validator-analyzer | opus → sonnet | NOT mixed: runs external validators (authoritative), fixed severity tables, base-100 deduction scoring, allowlist-driven fix bundle; ambiguity punted to user §6. No deep judgment present. (sub) |
+| onboarder | sonnet → haiku candidate | template-fill + conditional writes; only light stack-block filtering. (sub) Also inert-pin today. |
+| release-executor | sonnet (keep, borderline) | mostly script runs + CHANGELOG templating, but carries a NEED-DECISION judgment valve (MAJOR-bump wording). (sub) |
+
+### Split candidates (mixed classes inside one body)
+| agent | geometry (factual boundary) | complication |
+|---|---|---|
+| seo-analyzer | collection (STEP 2-5 curls/CWV/GSC/greps → haiku-class) / judgment (STEP 6-11 sampling, competitive, scoring, triage → opus) / templating (STEP 12-14 bundle+report → sonnet/haiku) | BDR-061: no Agent tool in analyzers (single-dispatch doctrine) → a split must be ORCHESTRATED BY THE SKILL at L1 with disk handoffs, or BDR-061 revised (nesting works ≥2.1.172 per BDR-060, but version-robust-by-design was chosen). seo-data.test.sh locks `fetch.sh` wiring strings IN the agent body (6 locks). STEP 1-2 context feeds every later step → large LRN-126 contract surface. |
+| geo-analyzer | identical 3-way geometry | same complications; shares severity vocab + sentinel |
+| commit-changer | MODE propose (narrative reconstruction + capitalize routing = deep) / MODE apply (stage+commit = mechanical) — boundary ALREADY exists as dispatch modes | 2 dispatch sites in /commit-change; per-dispatch `model=` override is an available lighter mechanism than a file split |
+| doc-syncer | drift detection + semantic doc-type analysis + MINOR/SIGNIFICANT calls (deep) / discovery + template render + PATCHED_FILES emit (mechanical) | 9 consumers on BOTH modes: dispatched ×2 (/doc, onboard) + inline-load ×7 (bugfix, hotfix, feat, init-project ×2, ship-feature, scaffolder) — LRN-125 dual-use-across-tiers hazard; runs its own user validation gate (STEP 8) → gate must be hoisted before any dispatch conversion |
+| handover-doc-writer | synthesis/vulgarization STEP 10-12 (deep) / render+deterministic gates STEP 13-16 (mechanical) | skill-leak ban list + `HANDOVER-DOC REPORT` grammar must survive |
+| plugin-advisor | detection PHASE 1 (mechanical) / complexity scoring + decision-table reasoning PHASE 2.5 (deep) | INERT PIN: inline-loaded ×4 (plugin-check, onboard, init-project, ship-feature), NEVER dispatched — sonnet pin is dead config; PHASE 4 asks the user (inline-only capability) |
+| verifier | STEP 2 evidence adjudication = deep judgment inside a sonnet procedural gate | BDR-066 kept sonnet DELIBERATELY (oracle-anchored to contract, ≤3×/loop). Tier-up = design arbitrage, not a mechanical fix. contract-verifier.test.sh locks name/tools/body (33 asserts). |
+
+### INERT-PIN finding (structural gap vs target)
+scaffolder, onboarder, plugin-advisor are pinned sonnet but NEVER dispatched —
+inline-load only → they run on Fable today. doc-syncer's doc-commit steps
+(bugfix/hotfix/feat/init-project/ship-feature/scaffolder) also run inline on
+Fable. Under the target policy these are EXECUTION tasks burning Fable — a
+bigger real gap than any pin value. Each inline→dispatch conversion must hoist
+its user gates into the dispatcher first (dispatched agents cannot ask).
+
+## CONSUMER MAP (summary; full tables in the dispatch-map sweep)
+
+- ~50 Agent() dispatch sites across 20 skills + 2 lib includes +
+  client-handover-writer (9 internal dispatches, incl. skills-via-general-purpose).
+- 20 inline-load sites (7× doc-syncer, 4× plugin-advisor, 3× analyzer, 2×
+  interviewer, 1× each onboarder/scaffolder/client-handover-writer/refactorer).
+- Includes: model-gate.md ×15 skills (+5 locked EXCLUDED), challenge-plan.md
+  ×12, verify-secure-loop.md ×5, contract-interview ×5, capitalize-commit ×6,
+  doc-commit ×6.
+- ~30 prose refs claim current tiers (sonnet-pinned X, opus-pinned Y, BDR-066/
+  BDR-076 citations) → all go stale on tier changes (LRN-113 sweep required).
+- Only onboard uses explicit `model="opus"` dispatch params (7 sites); every
+  typed agent relies on frontmatter pin; ship-feature/init-project mandate
+  `model: "sonnet"` on SDD subagents by prose.
+
+## CONSTRAINTS (zero-loss bar)
+
+1. Verbatim machine-parsed grammars must survive verbatim: `VERIFY — VERDICT:
+   CONFORME | ECARTS(n) | ERROR(<reason>)`, `SECURITY — VERDICT: PASS |
+   BLOCK(n) | ERROR(<reason>)`, `CHALLENGE — LENS: … — VERDICT: SOLID |
+   CONCERNS(n) | FATAL(n)`, mandatory `PROOF:` lines, sentinel `READY TO APPLY
+   — awaiting dispatcher confirmation`, `<NAME>-EXEC REPORT` + `STATUS : DONE
+   | NEED-DECISION | BLOCKED`, `PATCHED_FILES:`, `COMMIT PLAN`, labeled score
+   lines parsed by client-handover extractors, `HANDOVER-DOC REPORT`.
+2. BDR-050 + LRN-083: loops + decisions live in the MAIN loop; gates dispatched
+   fresh, blind, zero iteration history. Splits must not move loop decisions
+   into children.
+3. BDR-061: seo/geo/validator have no Agent tool by doctrine (version-robust
+   single dispatch level). Any intra-audit split is skill-orchestrated at L1
+   unless BDR-061 is explicitly revised.
+4. LRN-126: every implicit data path (ARGUMENTS flags, detected vars, STEP-N
+   side outputs) must cross the new handoff contracts explicitly; census-style
+   tests will NOT catch severed wires — a data-flow read per split is required.
+5. LRN-125: no dual-use agent across tiers; audit consumer routes to the
+   judgment agent, execution consumer to the executor.
+6. Interactivity: dispatched agents cannot ask the user. All human gates
+   (AskUserQuestion / inline approval) stay in main loop or inline-loaded
+   orchestrators. doc-syncer STEP 8 + plugin-advisor PHASE 4 gates must be
+   hoisted before dispatch conversion.
+7. Test locks (fire on this refactor): model-routing (~61, epicenter — pins,
+   dispatch strings, gate wiring loops, `model="opus"` literals, BDR-076 token),
+   plan-challenger (~43 — frontmatter, grammar, challenge-plan doctrine
+   sentences incl. BDR-066 token), loops-light (40 — verify-secure-loop 10
+   sentences, sonnet pins, report grammars, "Agent" ABSENT from
+   bugfixer/hotfixer — substring-fragile), contract-verifier (33),
+   security-auditor (31), seo-data (6 body-wiring locks on seo/geo bodies),
+   loops-heavy (19 skill prose), review-guards G3 (strict YAML on every agent
+   file incl. new ones), no-vacuous-locks (no `\n` in new lock patterns —
+   LRN-093), model-check (10 — tier vocabulary big/small; a new tier taxonomy
+   must co-evolve witness + test). Census `for`-loops (model-routing:13-19,
+   plan-challenger:42) must be edited for any new/renamed gated skill.
+8. model-gate.md prose has NO deterministic lock (include-path only) — free to
+   rewrite, but behavioral-only verification.
+9. Gitflow: feature branch(es) via gitflow.sh; no merge without human signal.
+   Unmerged branches in flight: `feature/opus-pin-audit-agents` (this refactor
+   supersedes/absorbs it), `bugfix/seo-geo-integrity` (10 commits touching the
+   seo surface → sequencing/conflict risk with a seo-analyzer split).
+10. BDR-076 survival: opus tier for judgment agents survives as baseline;
+    validator-analyzer's opus pin would be superseded (tier-down); seo/geo pins
+    refined by splits; challenge-plan/plan-challenger doctrine text + census
+    §11 rewritten again.
+
+## RISKS
+
+- Severed implicit data paths on splits (LRN-126 precedent: 2 silent input
+  losses caught only by whole-branch review) — probability: HIGH without a
+  per-split data-flow pass.
+- Consumer staleness (LRN-113): ~30 prose refs + 9 identical gate preambles +
+  2 census loops — partial sweep leaves contradictory doctrine — probability:
+  HIGH without whole-surface grep + new guards.
+- Lost human gates on inline→dispatch conversions (doc-syncer STEP 8,
+  plugin-advisor PHASE 4) — probability: MEDIUM-HIGH; hoist-first pattern
+  exists (BDR-066 wave 4 did exactly this for client-handover).
+- Census under-coverage: NEW agent files are silently unlocked unless
+  model-routing/census extended per agent (worse than a red) — MEDIUM.
+- haiku reliability on long tool chains (seo/geo collection legs: GSC, CWV,
+  curl loops, retry policies): only haiku precedent is status-reporter
+  (short, deterministic) — MEDIUM; unproven.
+- Split overhead: 3-dispatch audit pipeline re-serializes STEP 1-2 context per
+  child; latency + token duplication vs today's monolith — MEDIUM.
+- Merge sequencing with `bugfix/seo-geo-integrity` (10 commits on seo surface)
+  — MEDIUM.
+- Subagent-report trust (LRN-132): (sub)-marked classifications need spot
+  re-verification during design — MEDIUM.
+
+## OPEN QUESTIONS (design arbitrage needed)
+
+1. verifier: keep sonnet (BDR-066 oracle-anchored rationale) or lift to opus
+   (STEP 2 adjudication is the correctness gate)?
+2. seo/geo split mechanics: skill-orchestrated L1 pipeline (BDR-061-compatible)
+   vs nested dispatch inside the analyzer (requires revising BDR-061;
+   version floor OK per BDR-060)?
+3. Which inline-loads convert to dispatches (scaffolder, onboarder, doc-syncer
+   doc-commit steps, plugin-advisor detection) vs stay inline as reflection?
+4. commit-changer: file split vs per-mode `model=` override at the 2 existing
+   dispatch sites?
+5. haiku scope: which mechanical halves actually go haiku vs sonnet, given the
+   reliability unknown on long tool chains?
+6. Gate taxonomy: keep binary big/small model-gate (guards main loop only) or
+   extend model-check.sh to the full 4-tier vocabulary?
+7. Sequencing: land/absorb `feature/opus-pin-audit-agents` and
+   `bugfix/seo-geo-integrity` before or during this refactor?
+
+## DESIGN AMENDMENT (2026-07-19, user arbitrage — supersedes open questions)
+
+User approved all 7 recommendations, PLUS one addition:
+
+**No-inherit rule + fable pins.** No dispatched agent may inherit the session
+model anywhere. Every dispatch site carries an explicit tier: typed agents via
+frontmatter pin (`model: fable|opus|sonnet|haiku`), built-ins
+(general-purpose / Explore / Plan) via a `model=` param at EVERY call site.
+Rationale: sessions may run on another model (gate admits Opus; user may
+launch anything) — inheritance would silently mis-tier dispatched work.
+`model="fable"` lands where a dispatched child performs REFLECTION /
+ORCHESTRATION on behalf of the main loop:
+- client-handover-writer's 8 internal general-purpose skill-runner dispatches
+  (/seo, /harden, /cso, /commit-change, /web-validate runs) — today they
+  inherit; they host gated orchestration → `model="fable"`.
+- Doctrine line (model-gate.md or routing doctrine): ad-hoc reflection
+  dispatches from the main loop (Explore digest, Plan, general-purpose) carry
+  `model="fable"`; non-reflection ad-hoc dispatches carry their complexity
+  tier. New census locks accordingly.
+- No TYPED agent moves to fable tier (plan-challenger/analyzer stay opus per
+  approved verdicts). Inline-loads that remain (interviewer,
+  client-handover-writer, analyzer-in-/analyze + DEBUG, init STEP 2) ARE the
+  main loop — covered by model-gate, not pins.
+- External/gstack skills with inheriting general-purpose dispatches
+  (design-shotgun, review, graphify) — external ownership (BDR-015 class):
+  covered by doctrine, not edited, unless owned locally. Verify ownership at
+  implementation.

+
+Input: `.claude/tasks/plans/2026-07-19-model-tiering-v2-analysis.md` (read it
+first — consumer map, test locks, LRN/BDR constraints live there).
+User arbitrage (2026-07-19): 7 recos approved + no-inherit/fable-pin amendment
++ Fable scope = REFLECTION / ORCHESTRATION / PLANNING / LOGIC only.
+
+## D0 — DOCTRINE (end state)
+
+1. Main loop (session model, gated big by model-gate) keeps ONLY: brainstorm,
+   plan, contract, loop decisions, gate arbitration, human interaction,
+   conversation-context work (capitalize), trivial glue bash (<~1k tokens).
+   Retention criteria (any suffices): interactive | needs conversation context
+   | orchestration decision | dispatch overhead > step cost.
+2. NOTHING dispatched inherits. Typed agents: frontmatter pin. Built-ins
+   (general-purpose/Explore/Plan): explicit `model=` at EVERY call site.
+   VERIFIED (2026-07-19 spike, closes robustness BLOCKER): `model: "fable"`
+   on a dispatch resolves to claude-fable-5 at runtime (echo spike via
+   general-purpose); the harness enum-validates the `model` param — an
+   invalid value fails LOUDLY (InputValidationError), no silent fallback.
+   Call-site `model=` takes precedence over a typed agent's frontmatter pin
+   (documented Agent-tool contract); fallback direction if a call site omits
+   it = the frontmatter pin, i.e. today's behavior — fail-safe, never worse.
+3. Tiers: fable = dispatched reflection-on-behalf-of-main-loop (skill-runner
+   children ONLY); opus = deep judgment (audit scoring, plan critique, drift
+   semantics, review, synthesis); sonnet = standard execution from closed
+   instructions + collectors AND probes (wave-1 prudence — robustness MAJOR:
+   plugin PHASE 1 is a ~26-call branching bash chain, not a short probe);
+   haiku = status-reporter ONLY in wave 1; haiku expansion = wave 2 after
+   reliability proven per candidate.
+4. Grammars/sentinels/valves survive VERBATIM (list in analysis §CONSTRAINTS).
+   Loops/gates stay in main loop (BDR-050/LRN-083). Fix-bundle → L1 apply
+   (BDR-061) preserved: audit agents never get the Agent tool.
+5. Every split: LRN-126 data-flow pass (enumerate child-read fields vs
+   parent-set; explicit handoff contract on disk or in prompt) PLUS an
+   IN-WAVE planted-input smoke proving the fields cross the dispatch boundary
+   at runtime — the smoke GATES that wave's merge (confirmation MAJOR:
+   enumeration is design-time reading; census can't catch severed wires; a
+   split must never reach develop empirically unproven). Every change:
+   LRN-113 whole-surface sweep + census lock + flip-test (LRN-096, no `\n` in
+   patterns LRN-093, strict YAML G3).

+   project-signal presence) are PROBE REPORT fields. Handoff: PROBE REPORT
+   fields = plugin list, toggle state, profile, CLI/anim/monorepo/embedded
+   signals + checkpoint inputs (enumerate ALL PHASE-2-read fields).
+S2 doc-syncer → doc-auditor (opus; STEP 3-4 drift + semantic analysis + A3
+   MINOR/SIGNIFICANT call w/ doc-shape.sh oracle → DRIFT REPORT [AUTO]/
+   [HUMAN] items) + doc-syncer (sonnet; render/patch half, keeps
+   PATCHED_FILES: grammar + BDR-022 bans). Validation gate stays in
+   DISPATCHER (/doc skill, orchestrator steps) — auto-mode flows: auditor →
+   dispatcher applies AUTO via doc-syncer → SIGNIFICANT escalates inline.
+   Consumers rerouted: /doc, onboard, + doc-commit steps in bugfix/hotfix/
+   feat/init-project(×2)/ship-feature (inline→dispatch conversion) +
+   scaffolder PHASE 6 (scaffolder DISPATCHES nothing — it has no Agent tool:
+   README bootstrap moves to init-project STEP 5b dispatch of doc-syncer).
+   PLUS (robustness MAJOR): rework `lib/doc-commit.md`'s in-thread contract
+   BEFORE converting any doc-commit site — it requires the orchestrator to
+   "hold the patch context" to compose the rc-0 CHANGE SUMMARY (the review
+   surface that replaced the removed MINOR gate). Dispatched doc-syncer adds
+   a `CHANGE SUMMARY` block to its report grammar (per patched file: what
+   changed and why, ≤1 line each); doc-commit.md's composer consumes THAT
+   instead of in-thread context; census-locks the new field + a planted-input
+   smoke proves the summary crosses the dispatch boundary.
+S3 seo-analyzer → 2-WAY (simplicity MAJOR — 3-way was YAGNI while collector
+   and templater share the sonnet tier; commit-changer mode-precedent):
+   seo-worker (sonnet; `MODE: collect` = STEP 2-5 signals → SIGNALS file;
+   `MODE: template` = STEP 12-14 FIX BUNDLE + sentinel + SEO.md + envelope)
+   + seo-judge (opus; STEP 6-11 sampling judgment, competitive, scoring /20,
+   trajectory, triage → FINDINGS+PLAN). Orchestrated by /seo at L1 (BDR-061
+   conserved: no Agent tool in either). Wave-2 option: carve `MODE: collect`
+   into a haiku file once proven — the mode boundary IS the future cut line.
+   HANDOFF (robustness MAJOR — freshness/atomicity): run-scoped paths
+   `.audit/seo-signals-<RUNID>.md` / `.audit/geo-signals-<RUNID>.md` —
+   `.audit/` is the GITIGNORED derived-artifact tree (confirmation MINOR,
+   LRN-124: a crash-stranded transient with scraped GSC/competitor content
+   must never be committable; `.claude/audits/` keeps only the SEO.md/GEO.md
+   deliverables). RUNID minted by the dispatcher per run, passed to every
+   stage; the file ENDS with `COLLECTION COMPLETE — RUNID: <id>` and the
+   judge FAILS CLOSED (report ERROR, never score) if the file is absent,
+   RUNID mismatches, or the completeness sentinel is missing; dispatcher
+   cleans the file post-run.
+   DISPATCHER CONTRACT (confirmation MAJOR — fail-closed at the judge must
+   not fail OPEN at the pipeline): on a judge ERROR the orchestrator
+   (/seo /geo /harden /onboard) STOPS — no template dispatch, no L1 apply —
+   surfaces the ERROR verbatim, retries ONCE with a fresh collect+judge,
+   then escalates to the human. A mute or ERROR judge is NEVER carried into
+   templating (verify-secure-loop discipline). This handler is part of the
+   W5 skill rewrites, census-locked.
+   Explicit field list per LRN-126 (STEP 1-2 business+tech context consumed
+   by ALL later steps — full enumeration REQUIRED before cutting).
+   seo-data.test.sh locks (fetch.sh wiring) move with the worker body —
+   update suite same commit.
+S4 geo-analyzer → geo-worker (sonnet, 2 modes) + geo-judge (opus) — mirror of
+   S3 incl. run-scoped `.audit/geo-signals-<RUNID>.md` + the same dispatcher
+   ERROR contract. No cross-domain file share:
+   seo vs geo bodies genuinely diverge (different checks, scoring blocks,
+   envelopes) — that divergence, not LRN-125, is the reason.
+S5 handover-doc-writer → handover-synthesizer (opus; STEP 9 memory-registry
+   load + STEP 10 phase clustering + STEP 12 6-chapter synthesis — STEP 9
+   allocated here, it feeds the synthesis; correctness MINOR) +
+   handover-renderer (sonnet; STEP 13-16 annex render, precheck apply,
+   deterministic gates, HTML/PDF). client-handover-writer dispatches
+   synthesizer then renderer; PACKAGE contract split per LRN-126
+   (re-enumerate DEPLOY_HINTS/--skip-seo class fields — the EXACT prior
+   failure). W4 MUST same-commit relock model-routing.test.sh:52-55 (the
+   handover-doc-writer name + dispatch-string locks break on the rename;
+   "make test green per wave" D4 invariant — correctness MINOR).
+Tier-downs (no split): validator-analyzer opus→sonnet (deterministic
+   validators+tables). onboarder stays sonnet wave 1 (haiku candidate wave 2).
+   release-executor stays sonnet (NEED-DECISION valve).
+Verifier: STAYS sonnet (approved — oracle-anchored gate).
+
+## D2 — SKILL MAP (main loop = session model; every dispatch tier explicit)
+
+Gated reflection skills (model-gate kept, 15):
+- ship-feature / init-project: per the two example maps in the analysis file
+  (amendment section) + S1 gate hoist at STEP 0 + doc-commit conversions.
+- feat: scope/plan/contract/loop = main; challenge 3× plan-challenger opus;
+  feater sonnet; verifier+security sonnet; doc-commit → doc-auditor opus +
+  doc-syncer sonnet dispatch; commit via /commit-change (propose opus / apply
+  sonnet).
+- bugfix: investigation/diagnosis/contract = main (reflection); challenge
+  opus (3b); bugfixer sonnet; verifier+security sonnet; doc-commit as feat.
+- hotfix: LOCATE + guard = main (logic); challenge opus when guard fires;
+  hotfixer sonnet; security gate sonnet (revert-not-loop conserved);
+  doc-commit as feat.
+- analyze: analyzer INLINE = main loop (it IS the reflection) — unchanged.
+- code-clean: PHASE 1 audit inline = main (audit judgment feeding a human
+  gate); code-cleaner sonnet PHASE 2 (hosts refactorer inline at SAME tier —
+  LRN-125 OK); re-audit sonnet inside executor.
+- seo / geo: skill = orchestration + GATED arbitrage (main); pipeline
+  collector sonnet → judge opus → templater sonnet (L1 serial); appliers
+  hotfixer/feater sonnet at L1; build-verify inline.
+- web-validate: validator-analyzer sonnet; hotfixer applier sonnet; loop main.
+- harden: audit dispatch follows S3 narrow-scope path (seo-judge opus on
+  harden axes w/ collector reuse); direct-Edit apply stays inline (tiny
+  scope, BDR-061 carve-out conserved).
+- audit-delta: axis audits dispatched opus (delta judgment); security-auditor
+  sonnet; fix gate + markers = main.
+- tour: orchestration main; security-auditor sonnet; cleanup audit = analyzer
+  opus (or general-purpose model="opus"); fixes via sonnet appliers; doc axis
+  → S2 pipeline; reconcile axis = deterministic bash (main).
+- onboard: onboarder DISPATCHED sonnet (was inline); plugin S1 pipeline;
+  analyzer opus; general-purpose audits model="opus" (kept); seo/geo → S3/S4
+  pipelines; security-auditor + doc pipeline as above; synthesis
+  general-purpose model="opus"; backlog arbitration = main.
+- client-handover: writer INLINE (orchestrator, main); its 8 skill-runner
+  children model="fable"; handover S5 split (synth opus → render sonnet);
+  gates all main.
+Excluded-from-gate skills (5, stay ungated): commit-change (propose opus /
+  apply sonnet via model=; approval gates main); doc (S2: auditor opus →
+  gate main → patcher sonnet); status (haiku); release-candidate (executor
+  sonnet; version/when/push decisions main); refactor (refactorer sonnet).
+Memory/util skills (capitalize, close, prune-memory, reconcile, learn,
+  profile, skills-perso, gitflow, deploy, plugin-check(S1), status): main
+  loop by nature (conversation context, human gates, deterministic bash) —
+  no dispatch changes except plugin-check S1.
+External/gstack skills (graphify, design-*, review, qa, ship, investigate…):
+  NOT edited (external ownership, BDR-015 class) — covered by doctrine line;
+  local wrapper skills only if locally owned. Verify ownership per file
+  before touching (symlink → skip).
+
+## D3 — WAVES (each = gitflow feature branch, tests green, census extended)
+
+W0 SEQUENCING: merge `feature/opus-pin-audit-agents` → develop (baseline,
+   human gate). `bugfix/seo-geo-integrity` is ALREADY MERGED (correctness
+   MAJOR — the TODO.md "UNMERGED" note was stale; verified `92301fe` is an
+   ancestor of develop AND this branch): no arbitrage, no W5 wait — one-line
+   ancestry re-check in W0 + fix the stale TODO.md entry (reconcile-class
+   correction). Absorb the analysis+plan files into the new feature branch.
+W1 NO-INHERIT ENFORCEMENT (small, high-value): code-review model= opus
+   (ship-feature 6, init-project 10); client-handover-writer 8× model="fable";
+   doctrine line in model-gate.md + census locks (`model="fable"`,
+   `model=` presence per site); SDD sonnet prose → census lock. Prose sweep
+   of stale BDR-066/076 claims touched by W1.
+W2 INLINE→DISPATCH CONVERSIONS: scaffolder (init 5 — liveness pings move to
+   orchestrator; scaffolder loses PHASE 6 inline-load → init 5b owns README
+   via S2), onboarder (onboard), doc-commit steps ×5 flows → S2 pipeline
+   (gate hoist FIRST: /doc + flows own the validation gate; doc-syncer body
+   loses its inline gate → census re-lock), S1 plugin split + gate hoist ×4
+   consumers. Data-flow pass per LRN-126 on each (fields enumerated in the
+   wave's contract file before edits).
+W3 TIER MOVES: validator-analyzer → sonnet (pin + prose + census flip);
+   commit-changer per-mode model= (2 sites + prose + census).
+W4 S5 handover split (synth opus / render sonnet) + PACKAGE re-enumeration.
+W5 S3/S4 seo/geo pipelines: worker(2-mode)/judge ×2, /seo /geo /harden
+   /onboard rerouted, seo-data.test.sh moved locks, run-scoped signals
+   handoff (RUNID + completeness sentinel + fail-closed judge),
+   envelope/sentinel/score grammars verbatim, COVERAGE lines preserved.
+W6 DOCTRINE + CLOSE-OUT: model-gate.md rewrite (protects main loop; tier
+   table; fable-dispatch doctrine), challenge-plan.md + plan-challenger
+   ORCHESTRATOR PROTOCOL text (keep BDR-066+BDR-076 tokens per census, add
+   BDR-077), census consolidation (model-routing new sections; every new
+   agent: YAML G3, pin lock, dispatch-string lock, AskUserQuestion/Agent
+   bans), LRN-113 whole-surface prose sweep (~30 refs list in analysis),
+   BDR-077 + LRN entries + journal, EVAL-023-style post-merge ronde.
+   Per-split planted-input smokes run IN their own waves (W2/W4/W5, merge
+   gates) — W6 is the consolidated ronde only, never the first empirical
+   proof of a split.
+
+## D4 — ZERO-REGRESSION PROTOCOL (every wave)
+
+- Before edits: wave contract file (.claude/tasks/contracts/) with FILE SCOPE
+  + acceptance criteria; challenge-plan on THIS plan (done once, below);
+  verify-secure-loop on each wave's diff (verifier sonnet + security sonnet).
+- Grammar diff-guard: `grep -F` each verbatim marker (analysis §CONSTRAINTS
+  list) pre/post per wave — zero drift.
+- Census: flip-test every NEW lock (plant violation → RED) before trusting.
+- `make test` green per wave; no wave merges without human signal (gitflow).
+- Rollback story (robustness MINOR — waves are textually interdependent, an
+  early wave is NOT independently revertible after later merges): revert in
+  REVERSE merge order, or revert the whole stack; never a mid-stack single
+  revert. Pre-merge, the rollback unit is the wave branch.
+
+## CHALLENGE LOG (2026-07-19 — 3 blind lenses on plan v1)
+
+- correctness: CONCERNS(2) — seo-geo-integrity phantom sequencing (fixed W0);
+  commit-changer precedence ambiguity (fixed D1 + D0.2 citation + W3 smoke);
+  3 MINORs (S5 STEP 9 + W4 relock; plugin checkpoint seam; templater label)
+  — all fixed in place.
+- robustness: FATAL(4) — BLOCKER fable-dispatch unverified → CLOSED by spike
+  (D0.2: resolves to claude-fable-5, enum-validated, loud failure); doc-commit
+  in-thread contract (fixed S2: CHANGE SUMMARY crosses the report grammar);
+  plugin-probe haiku contradiction (fixed: sonnet wave 1); signals handoff
+  freshness (fixed S3: RUNID + sentinel + fail-closed); rollback claim
+  (fixed D4).
+- simplicity: CONCERNS(1) — 3-way seo/geo YAGNI → 2-way worker/judge (fixed
+  S3/S4); twin-templater share (dissolved by 2-way; divergence stated);
+  plugin gate ×4 copies → lib/plugin-gate.md include (fixed S1).
+- Confirmation pass (fresh robustness challenger on v2): CONCERNS(2) — v1
+  fixes HOLD (doc-commit CHANGE SUMMARY, plugin-probe sonnet, rollback order,
+  fable spike, RUNID); 2 new MAJORs + 1 MINOR opened by the revisions, all
+  fixed in v3: (a) per-split planted-input smokes moved IN-WAVE as merge
+  gates (W6 = ronde only); (b) dispatcher ERROR contract on judge failure
+  (STOP, no templating/apply, retry once, escalate — pipeline never fails
+  open); (c) transient signals files relocated to gitignored `.audit/`
+  (LRN-124). Protocol cap reached (1 re-challenge) → to the human gate.
