# CURRENT PHASE — Phase 31: The Frontier Atlas & Wide-Tolerance Campaign

**Started:** 2026-08-14 · **Plan approved:** 2026-08-14 (gate 1; Drew) · **Effort doctrine:** xHigh default / Max deep (T5, T7, synthesis) / Ultracode waves (R26/R27 prompts) / Fable-tier only for new wall classes.
**Approved plan:** `/home/musashi/.claude/plans/fable-5-set-max-goofy-seahorse.md` (the full design; this file is the crash-recovery log).
**Approval also ratified R37 (probe before costing), R38 (read recorded failure verdicts first), R39 (negative-control new refusal-checks) — now binding.**

## The re-charter (one paragraph)

Instead of roadmap-v2 P31's per-function grind, Phase 31 organizes the 12,059 remaining stubs (main 1,041 · resident 14 · ov 9,832 · md 1,179) into **crack groups**: a deterministic per-function feature layer + multi-tier similarity atlas (li-normalized exact tier, seed sweep vs the 2,719 matched skeletons, calibrated warm tier for the 3,238-unit cold tail + main, kNN neighborhood graph), evidence-joined to a lever label per group; plus **widened mechanical lanes** (LEN-tolerant aligned remap with a fully-mechanical LI class, §172b EXTPAIR/SELECT detectors + routing, PLUMBING campaign, permuter cluster warm-start, weak-seed cards); then a **campaign loop to ceiling** — deterministic $0 lanes first, agents only for exemplars, velocity-ledgered, closed on measured decay. Milestone shape = P30 (campaign to ceiling; every remaining stub on a named ledger at close). Main fully included from day one.

## Progress log

- 2026-08-14 — Phase planned and approved (3 Explore + 2 Plan agents; full design in the plan file). Task list built (harness tasks #1–#12). T0 started.
- 2026-08-14 — **T0 COMPLETE.** (1) R31 decision-log entry (the re-charter WHY + R37–R39 ratification). (2) `harvest_verify.py` import guard: a bare import now RAISES instead of running a gate (verified both directions; CLI behavior unchanged). (3) **Resident ±1 RESOLVED + FIXED**: `--bootstrap`'s linear partition had fused the +0 data word with `func_800CEDFC` (row `0x800CEDF8` nins=18) and dropped `func_800D33E0` past a glued tail — the true denominator is **145** (progress was right, the sig wrong). `sig-resident` now ELF-seeds (S45 pattern: unique 4-aligned T-symbol addrs inside the `resident_TEXT_START/END` markers → exactly 145; bootstrap fresh-clone fallback). All three oracles now agree (sig 145 · corpus matched 131 · progress byte-ident 131); `audit-corpus` 0 PHANTOM + 0 TRUNCATED. (4) Family maps regenerated at HEAD `commit:2161`: **11,025 open non-main members = 12,059 − main's 1,034 EXACT** (the stale map's 102 phantoms cleared); cousins totals now A-prop 1,125 / seeded 1,293 / cousin-multi 5,373 / cold 3,234 inst; adapt cards 704, aprop cards **204 (full emission)**. (5) **Main fuel gap is DEAD**: 2,001/2,002 main stubs have cached Ghidra-C (only `func_80049600` missing) — the roadmap's "0/2,096" note was stale. (6) `make tools-health` → OK (dedup 2,063/0; C1 254,521/254,521; audit-digest confirms the fleet digest; resident fix moved instr num+denom by the same +9).

- 2026-08-14 — **T1 COMPLETE: 8 banked for 0 agent tokens.** R38-first: partitioned the MATCH-108 pile against current stubs (75 still open) and against the S50 gate history (62 gated-and-failed with verdicts · 13 never-gated). The lanes and their measured outcomes:
  - **Never-gated 13** → gate_lane: 0/13, but the verdicts decomposed to 11× `undefined reference to D_*` = the §171 stale-seed-symbol class. **Extended `aprop_symfix` with STALE-DELTA** (n:n uniform-delta rebase; R39 synthetic + snapshot NCs, zero false positives; the delta test even refused a pair my hand-check wrongly accepted) → 4 rebased, **4/4 banked** (`func_8016BCC0`, `func_8017F1C8`, `func_80186BD8`, `func_80186BF8`). Cookbook **§171-D** written in-session.
  - **SELF-decl PLUMBING 7** → `recover_integration --stages demacroize --max-tier binary`: **4/7 banked** (`func_80139BE0`, `func_8014ED28`, `func_80161D88`, `func_801659DC`); 3 stay near.
  - **Stored-draft re-gates** (no-verdict 7 + close=0 8 + diff 1 + 9 STALE→clean world-motion drafts): **0/23-ish banked** — the ~8% A10 stored-verdict law held again; all re-verdicted fresh.
  - **Handed forward with fresh classifications**: CALLEE-decl 15 + CC1-FAIL 14 → T6 (cast-callees/tu-scope stages); UNDEF-DATA/OTHER 9 → the §171b-1 data-definition carry (T7/T8); md CARVE-REFUSED 8 → campaign side-quest ledger. immfix pile: fully consumed (0 open). fix20: 19/20 consumed in S50.
  - Tool fixes landed: `gate_lane` propagate-commit tag now derives from GATE_PHASE (was hardcoded phase-30 S49).
  - Rate lesson for the velocity ledger: fresh-fix lanes (STALE-DELTA 4/4, demacroize 4/7) vastly outperform blind stored re-gates (0/23) — the campaign loop's L2 ordering is confirmed by measurement.

- 2026-08-14 — **T2 COMPLETE (references).** (1) **PsyQ dev-CD extracted**: walked the on-disk Track-1 image (MODE2/2352) with the frozen `tools/bfm_extract/iso9660.py` (R33 — no new extractor; walker = iter_directory/read_extent with out-of-range extents skipped) → `tools/reference/psyq-sdk/` (gitignored): 2,374 files / 231.6 MB, **400 C sources (373 in PSX/SAMPLE/** across CD/GRAPHICS/SOUND/MODULE/CMPLR/…); only 7 out-of-track `.DA` audio skipped. (2) **Provenance find**: `GNU/SNGNUVER.TXT` = SN Systems' gcc build history (`2.7.2.SN32.3.7.0002`, 14.5.97) with per-build changelog of SN's patches vs vanilla — only `UNROLL.C` (parameterised max unroll insns) is codegen-relevant; recorded in the idiom notes as the first-look suspect if a loop-unroll residual ever defies the vanilla model. (3) **gcc-2.7.2 reference completed**: +6 files from GNU ftp (`calls.c` + `caller-save.c` — both cited by §172's producer model, previously missing — + integrate/optabs/varasm/recog), tarball sha256 `7cd8bce5…` recorded. (4) `docs/psyq-sample-idioms.md` seeded (inventory, provenance, first style conventions, the lane hook); SETUP §5.6 rows added (R21).

- 2026-08-14 — **T3 COMPLETE (main enablement).** (1) `sig_image` seed-ends extension: `--seeds` now accepts `0xADDR NINS` lines (and jsonl `nins`); a seeded nins is authoritative — the slice is exactly `[addr, addr+4·nins)`, bypassing `func_end` (whose heuristic mis-sliced 3/40 main samples). (2) `corpus.s_ins_count()` factored from audit() (R33, one counter) + `corpus.py <bin> --seed-ends` CLI. (3) **`make sig-main`**: 2,002 main stubs signed at splat-true lengths → `.run/sig.main.jsonl` (deliberately splat-SEEDED — the atlas needs the boundaries a match must hit; NOT the independent second oracle, which stays deferred per `docs/second-oracle.md`). (4) **Full word cross-check: 2,002/2,002 slices byte-faithful** (EXE bytes vs `.s` comment-column words; 0 SLICE-SUSPECT; note the `.s` word field is byte-order hex, not the LE-decoded value — first checker draft compared wrong and read 1,999 false suspects). (5) `family_remap` main special-cases: `vram_of('main')` = code-segment `vram − start` from `splat.us.exe.yaml` = 0x8000F800; `img_path('main')` from the same yaml's target_path (R33). `stream_words('main')` == `.s` words on **25/25** samples. (6) Regression: `sig-resident` re-run **byte-identical** after the shared `read_seeds` change.

- 2026-08-14 — **T4 COMPLETE (`tools/atlas_features.py`).** Per-function features memoized per distinct `h_exact` (`.run/feat_memo.json`) and fanned out 1:1 with sigs to `.run/feat.<bin>.jsonl` ×213 (main reads the splat-true `sig.main.jsonl`; registry untouched). **363,525 rows / 92,855 distinct bodies in 21 s** (vs the 3–6 min estimate). Features: nins/band · o0 prologue tell · frame/callee-saved set+order/fp · CFG skeleton (nblk/ncond/nback/ret_n via branch-target scan; jal = call, never an edge — position-independence proof in the docstring) · mid_jr/jalr · stable-call-sequence hash (fixed main+resident ranges) · reloc-kind sequence hash · 16-bucket ophist · **§172b tells as importable shared functions (extpair/dupselect/sign_mix/magic_div — T8's len_tells imports these, R33)** · **li-normalized skeleton `h_seqn`** (non-anchor lui dropped, ori→addiu class). Verifies: R32 join asserted per binary at write; determinism 0 mismatches on 200 re-derived bodies; **mid_jr cross-check vs family_hseq's independent oracle: 6,444/6,444 exemplars agree** (first verifier draft compared ZERO rows — a string-vs-int addr type mismatch, the R32 silent-no-op class caught in my own verifier; now indexed + fails loud if compared==0). o0-tell vs `corpus.is_o0` on 13,019 open fns: 41 both / **94 tell-only = candidate undiscovered -O0 fns in -O2 TUs (§116 — o0_subsplit carve fuel for the campaign)** / 14 src-only outliers.

- 2026-08-14 — **T5 COMPLETE (`tools/atlas.py` + `make atlas`) — THE FRONTIER ATLAS EXISTS.** Survey in 92 s, all assertions green: **5,139 groups cover ALL 12,058 open instances / 613,710 ins** (12,058 = progress's 12,051 stubs + 7 NON_MATCHING exactly — the +1-blob and +8-banked discrepancies were both chased and resolved: data blobs excluded, T1 banks confirmed absent; main open reconciles to classify()'s stubs+NM with a hard assert). Tiers: **calibration measured** (positives = cousin ≥0.85-raw merges, negatives = size-matched cross-unit pairs; the li-normalized metric is so discriminative that recall ~99% holds down to 0.55; rule = smallest t with neg-accept ≤0.2% ∧ recall ≥95% → **THRESH_WARM=0.70** at 99.1%/0.18% — chosen because a false warm-merge wastes an exemplar crack, a miss only routes cheaper) · T1.5 h_seqn 2 merges · **warm tier 1,019 merges** · **seed sweep: 4,702/7,247 open skeletons (65%) carry a ≥0.55 matched seed** from the 2.7k-skeleton pool · kNN graph (top-8 open + matched neighbors) · tiny-direct. **Lever table (the strategic map):** head-crack 1,283g/186.9k ins · UNKNOWN 1,964g/138.6k (honest) · **extend-tell 575g/76.7k** · redraft 46.8k · **jtbl-carve 190g/45.7k** · integration 575 inst/23.4k · seeded-crack 23.4k · len-vein 778 inst/16.8k · swaprepeat 9.2k · plumbing 161 inst/8.1k · o0-lane 6.6k · cc1 6.4k. Top group: 268 drifted single-member skeletons unified (per-location ~23-ins family, 0.72 seed). Evidence joins accounted (audit/backlog/ledgers/cards; residuals EXCLUDED-STALE until regenerated); `--targets` resolves 12/12 `.s`. `make atlas` = the full regen chain. docs/frontier-atlas.md committed.

- 2026-08-14 — **T6 IN PROGRESS (PLUMBING campaign) — probe converged after two R14 corrections.** `plumbing_groups.py` derived the honest pool: **237 still-open** PLUMBING rows (the "1,217" was ledger-vintage inflation): SELF 109 (3 concentrated binaries) · CALLEE 48 · OTHER 48 · DATA 32. Probe (ov_SC03_107 SELF-21 → 14 with drafts): first run **0/14 with a PHANTOM shared error** — root-caused to **cross-group TU-edit poisoning** (a demacroize edit in TU-A persists while TU-B's drafts gate; every whole-binary build compiles ALL TUs) → fixed `recover_integration` with per-group isolation (git-checkout binary TUs between groups, gate_lane's proven pattern; engine_core.h untouched so fleet-tier arity persists) + added the **`macro-externs` draft stage** (§121: one draft's guessed `extern int f()` vs the TU's `DEFINE_`-macro definition — lifted from family_sweep, R33) + **`tu-scope` stage** (§103 STU, the sweep-only lever). Isolated re-run exposed the TRUE class: `undefined reference to D_*` = **the §171 stale-seed-symbol class** (rtu_match MATCHes these drafts — it is blind to relocation names; the R34 two-oracle disagreement exactly as documented) → **symfix-first**: 11/11 rebased (mixed 1:1 + n:n deltas incl. the S49 Δ0x4128) → **9/14 banked (64%)** where the raw path scored 0. The standing recipe: `aprop_symfix --fix → recover_integration --stages macro-externs,demacroize,tu-scope` (per-group isolated). Full sweep over the remaining ~200 rows now running.

- 2026-08-14 — **T6 COMPLETE.** Sweep over the remaining ~200 rows: **the decisive finding is Law 3 (§173)** — the biggest groups (ov_SC02_037 44 rows, most of ov_MAIN_012's 42) have **zero stored drafts**: their PLUMBING verdicts came from transient family-sweep remaps never persisted to the backlog. A recovery lane can only recover what was stored — verdict-only rows are family-lane fuel (already atlas-labeled), not recovery fuel; the true stored-draft class was largely consumed by the probe (**9 banked, 64%**). Singleton tail with drafts: 0/~20 (fresh per-fn verdicts recorded). Cookbook **§173** (symfix-first · per-group isolation · verdicts-without-drafts) + index regenerated (518). **R22 clean fleet: 213/213** with all T6 banks. Phase total so far: **17 banked, 0 agent tokens** (stubs 12,059 → 12,042).

- 2026-08-14 — **T7 COMPLETE (honest refutation).** `tools/family_align.py` built: aligned classifier (SequenceMatcher over FC.tok; LEN-LI/LEN-NOP/LEN-JTBL/LEN-STRUCT/STRUCT-ALIGNED/PURE/IMM verdicts) + li-cluster reconstructor (with the split-cluster absorb for the rs-changed addiu partner) + the aligned imm engine. **NC-1: 157/157 verdict-equivalence** with classify_member on banked pairs — the NC itself caught two real classifier gaps (R-type non-shift sa = STRUCT; registers tested BEFORE the reloc skip — a reloc-slot word with a different register is STRUCT). NC-2 parity 21/21. **The R37 probe then killed the planned driver before it was built: 0/26 LI-ONLY cards classify mechanically** (regfields drift ×19) — cousins are 0.85-similar DIFFERENT functions; §168 law 1 ("a cousin is a seeded crack, never a remap") re-derived by measurement. The engine's true consumer is **T8's LEN+N pile** (draft vs its own target = same function). Parked for T8: the reloc-vs-constant range discriminator for lui-bearing clusters. Decision-log entry written (R31).

- 2026-08-14 — **T8 COMPLETE (LEN+N lane).** Built: `match_one --emit-streams` (additive, stdout-identity NC'd) · `family_align.addr_true_rel` (the reloc-vs-constant range discriminator — full conservative set kept for pair semantics/NC-1 [157/157 regression], address-true subset for indel eligibility; synthetic probes: lui-bearing constant cluster now LEN-LI, address-anchored indel still refuses) · `tools/len_tells.py` (per-draft aligned classification + §172b tell tagging on target-side indels, detectors imported from atlas_features R33, cookbook text embedded in cards) · `tools/lenmiss_route.py` (pool-parallel per A8: **587 audit LEN rows re-verified live and routed in 24 s**). **Routing:** redraft **345** (frac>0.35 — the draft is not the function; reclassified APPEND-ONLY in the backlog, so near-miss metrics stop lying) · permuter-length **49** (|Δ|≤2 clean drift — grinder fuel) · cards **192** incl. **14 EXTPAIR/SELECT/NOP-tagged** (the audit's own detectors had emitted zero — these are new signal) · **mechanical 0 — an honest null**: stored drafts rarely get CONSTANTS wrong (agents copy them from asm); LEN drift is shape, so the LI-cluster swap lane has no fuel in this pile and family_align's value here is the classifier/detector. R32 accounting 587/587.

- 2026-08-14 — **T9 COMPLETE.** `tools/warmstart.py` (the permuter/grinder FEEDER): `--from-banked` walks a banked exemplar's h_seq family's still-open members, builds remapped proven-body drafts (`symbol_map` + `aprop_autodraft.build_draft`, refusing on reloc-count mismatch), **stream-classifies member-vs-seed with ZERO compiles** (masked_diff-shaped dicts from ground-truth bytes → `residual_class.classify_streams`), enqueues ONLY permuter-shaped (bucket==permuter or LENGTH-DRIFT |Δ|≤2) as backlog near-records; `--lenmiss` ingests T8's 49-route. **Grinder patch NOT needed** (its candidates() deliberately keeps unclassified records — "unknown is not a reason to skip" — so pre-filtered enqueues flow as-is; documented in the feeder's docstring). Armed live: **49 + 10 enqueued, 120 refused** by the stream filter (the anti-92%-wasted-CPU discipline working). `family_cousins --weak-cards`: **954 units** (the 0.70–0.85 annotate-only band, never before consumed) as seeded-crack cards, ins-ranked, §168 laws embedded, model-routed **haiku 804 / v3 43 / sonnet 86 / opus 21** (cheap tiers dominate — the token-efficiency shape), 0 unresolved `.s`.

## Campaign velocity ledger (T10+)

| wave | lane | cards | standalone MATCH | banked | tokens | tok/bank | lesson banked |
|---|---|--:|--:|--:|--:|--:|---|
| A | adapt SMALL-EDIT | 24 | 18 (75%) | **12** (+1 prop) | ~1.40M | **~117k** | zero stale seed-symbols (the §171 prompt-law works); 6 gate-fails all INTEGRATION shapes (3× decl-type vs TU, 1 arity, 2 TU-context DIFF) → wave-B prompt adds match-the-TU's-existing-decl |
| grinder-1 | permuter | 10 | — | 0 | $0 | — | func_800CB4CC parked at best-1 (warmstart seed); queue enriched +59+6 records since |
| C-probe | tell (3) | 3 | 1 (33%) | **1** | ~300k | ~300k | §174 **Law 4**: the TU's decl of YOUR OWN fn constrains the def sig — standalone MATCH gated 0/1 until canonical-sig + cast-at-use; tell attribution unreliable (2/3 residuals were a different class) |
| C | tell 11 + weak 24 | 35 | **35 (100%)** | **32** (8 propagated ×2) | ~2.39M | ~75k | Law 4 in-prompt → 0 symbol fails, 91% gate; **weak lane 24/24 on haiku — the 890-card vein is live**; 3 NEAR → grinder |

- 2026-08-14 — **CAMPAIGN OPEN (T10+, Ultracode).** Wave A: 24 adapt cards → 18/24 standalone (75%) → symfix-first (0 stale — the prompt-law worked) → gate **12 banked + 1 propagation** (~117k tok/bank e2e; stubs → 12,030). 6 NEARs (3 at close ≤3) enqueued to the grinder. Wave B (48 cards, all haiku, 29 binaries) launched with the decl-matching lesson. Grinder pass 1: 0/10 but func_800CB4CC at best-1.

- 2026-08-14 (resume session) — **Checkpoint resume steps 1–2 DONE.** (1) **R22 owed proof banked: `make clean && make extract-all && make check-all` → 213 passed, 0 failed of 213** (`.run/r22_p31_resume.log` EXIT=0) — wave B's banks verified fleet-clean. (2) **`make atlas` regenerated at HEAD `commit:2234`**: 363,525 feature rows / 92,855 distinct bodies (0 newly computed — memo hit); **5,144 groups / 11,994 open instances / 612,325 ins**; warm merges 1,014; seeded 4,710/7,247 skeletons; all assertions green. Open count 12,058→11,994 reconciles with the session's 65 banks. (3) Wave C fuel verified: `.run/wave_p31c_cards.json` = 38 cards (14 tell/sonnet + 24 weak/haiku); grinder idle (heartbeat `done`); gate free. Drew's re-extraction question answered (disc/splat layers gain nothing — deterministic + continuously regenerated; sig/atlas layer regenerated by this step; Ghidra-C re-analysis = targeted-probe candidate only, R37). NOTE: this harness build has no TaskCreate tool — this checklist + log is the monitorable task view (R28 noted plainly).

- 2026-08-14 (resume session, cont.) — **WAVE C COMPLETE: 32 banked, R22 213/213.** Probe→wave cadence (§174 law 3) paid: the 3-card probe cost ~300k tok and returned Law 4, which the 35-card wave then converted at 91% gate with zero symbol failures. Independent re-verify of all 35 drafts by me (R14) before gating: 35/35 MATCH held. **Reach measured honestly: 32 exemplars, only 8 had any sharer, each ×2 → ~1.25× effective.** The ×134 era is over (P25/29/30 harvested the shared cores); fleet-% now moves ~1:1 with exemplars banked, so THROUGHPUT is the lever, not leverage.
  - **THREE instrument defects found+fixed in my own new tooling this cycle** (the R32/R35/R39 class, and the reason R39 exists): (1) `build_wave.py`'s gate-guard used `pgrep -f` via `shell=True` — the wrapping `sh -c` carries the pattern in its own cmdline so it self-matched and refused forever; fixed by invoking pgrep without a shell. (2) The open-stub predicate did `fn in corpus.stubs(binary)` — but `stubs()` returns **addr→Stub**, so every card looked "already-banked" and BOTH pools reported ~0 candidates (I nearly concluded the 622-card adapt pile and 954-card weak pile were spent). Fixed to `{st.symbol for st in ...values()}` and **negative-controlled against the known population** (35 wave-C cards, 32 banked → exactly 3 still open: PASS). (3) I fired wave D once with hand-typed placeholder card names instead of the generated file — caught and stopped within a minute, relaunched from `.run/wave_p31d_args.json`. Recorded, not buried (P9).
  - **Pools are NOT spent (post-fix, honest): adapt 569 candidates, weak 890 candidates.**
  - **STRATEGIC (Drew's question "why are our waves so weak?" — he is right):** the card lanes I have been drawing from are the *mechanical leftovers* (12–42-ins cousins), ≈1,400 ins/wave against 612,325 open ins ≈ **0.23%/wave**. The Atlas already maps where the mass actually is: **head-crack 1,276 groups / 4,248 inst / 186,291 ins** (≈3.3 inst per group — a group head crack banks its members), **UNKNOWN 1,964 / 138,597**, extend-tell 575 / 76,730, redraft 280 / 46,769, jtbl-carve 190 / 45,673. And high-reach groups DO remain: gid `96f8b78ec8d3` = **265 instances / 6,084 ins** (integration lever, 31-ins exemplar), `75cec648ba15` = 116 inst / 3,002 ins, `152d63c1086d` = 64 inst / 1,559 ins. **Next: build the wave generator off `.run/atlas.json` groups (top instruction-mass first, routed by the group's measured lever) instead of the leftover card piles.**

## Blockers

## 🛑 SESSION CHECKPOINT (FINAL for this session, 2026-08-14 — campaign mid-flight, resume in a fresh session)

**Phase 31 CONTINUES (campaign-to-ceiling; do NOT close).** Session totals: **65 banked** (17 mechanical @$0 + wave A 12+1prop @~117k tok/bank + wave B **35/37 gated, 95% conversion** @~88k tok/bank — the decl-matching lesson nearly eliminated integration failures). Stubs ≈ **11,995** (from 12,059). All banks byte-gated + committed; wave banks propagated where sharers existed.

**RESUME STEPS (fresh session, after the standard load order):**
1. `git log --oneline -20` to see the wave-B bank commits; run **R22** (`make clean && make extract-all && make check-all` → expect 213/213) — it was NOT run after wave B (context ran out; the per-bank gates each verified their own binary, but the standing clean-fleet proof is owed FIRST).
2. `make atlas` (regenerates maps + atlas post-banks, ~15 min, $0).
3. **Wave C is STAGED, not launched**: `.run/wave_p31c_cards.json` (14 §172b tell-cards [sonnet] + 24 weak-seed haiku cards — measures the two untested agent lanes). Launch via the persisted workflow script `workflows/scripts/p31-adapt-wave-a-wf_2fbef223-859.js` pattern (args = the cards; NOTE the tell/weak cards have different fields than adapt cards — adapt the prompt per lane or write a v2 script). Needs `/effort ultracode` (R27).
4. Adapt pile remains ~630 SMALL-EDIT cards — the proven 73-95% lane; wave D+ = next 48 by the same selection (exclude banked; see `.run/wave_p31{a,b}_cards.json` for taken).
5. Grinder queue armed: 59 warmstart + 6 wave-A NEARs + 8 wave-B NEARs (4 at close ≤3). Relaunch: `GATE_PHASE=phase-31 .venv/bin/python tools/grinder.py --once --batch 15 …` (single-writer: never while a gate runs).
6. Ledger discipline: velocity row per wave (the table above); distill lessons per R16/R30; close the phase ONLY on measured multi-session yield decay (plan file §Leg-C).

**Watch-fors:** gate_lane aborts on dirty src/config (clean first); symfix-first before every gate (§173); the safety-classifier can rate-limit under 48-agent bursts (harmless — retry).

## (superseded) previous checkpoint (end of build arc)
**T0–T9 ALL COMPLETE AND COMMITTED** (through `commit:2181`). Phase totals: **17 banked, 0 agent tokens**; stubs 12,059 → 12,042; R22 213/213 verified twice (post-T1, post-T6). The machine: the Atlas (5,139 groups, `make atlas`), the widened lanes (symfix STALE-DELTA, recover_integration isolation + macro-externs/tu-scope, family_align + len_tells + lenmiss routing), the armed queues (grinder: 59 warmstart records; cards: 954 weak + 192 len + 704 adapt; permuter-49). NEXT = **T10+ the campaign loop**: L3 grinder running in background (launched at checkpoint time); **card/crack WAVES need Drew's `/effort ultracode` toggle first (R27)** — prompt and WAIT. Campaign cadence + close criterion: the plan file §Leg-C. If resuming fresh: read the approved plan + this log; check `.run/auto/grinder_heartbeat.json`; run `make atlas` to refresh; continue the loop.
