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.

🛑 SESSION CHECKPOINT (refreshed 2026-08-14, end of the 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.
