o0b-bearing != o0b-adjacent: T85's 0x801457A4 banked by append only because it abuts the o0b object's END; the 0x8013Bxxx-0x8013Cxxx families mis-place by construction (probe 1/1 gate-reject) and per-fn isolation IS the Arm-A re-carve. Frontier report corrected; T2 pivots to the Arm-A +0x20 defect itself (symbol-pin hypothesis first). Driver stands as the post-fix sweep harness.

The P30 frontier report (T0(f) — report point #1)
Generated 2026-07-30 at HEAD
commit:1218, after the T0 instrument repairs (a–e), from same-tree regenerations only:progress.fleet.md·family-hseq.md(+.run/family_hseq.json) ·worklist.md·.run/fuel_manifest.json·.run/autopsy/residuals.jsonl·docs/autopsy.md. Every number below is re-derivable from those artifacts at this HEAD (R33/R35). This file is a point-in-time report — it is NOT re-baselined; consume via a fresh regen.
Standing
87.5% instr (11,493,049/13,141,652) · 78.0% distinct (4,396,900/5,634,875) · 92.00% fn-count (325,417/353,720) · 140/140 byte-identical (R22 re-proven this session after the 21-file include fix) · dedup 1886/0 · 0 NON_MATCHING.
Open: overlays 27,248 instances / 17,629 distinct / 1,587,311 ins · main 1,034 stubs (0.7% game-code) · resident 14.
The pinned populations (what T0 was for)
| population | pinned value | consequence |
|---|---|---|
| Stranded byte-correct drafts (T1 fuel) | 108 match_one-MATCH + 1,178 near + 63 nobuild (autopsy, 1,349 rows, 0 classifier errors, second-oracle agree) | T1's recovery sweep has 3× the population the S16 sample suggested (36 → 108 fresh MATCHes) |
The -O0 cluster (T2) |
18 families / 2,192 open members (2,131 on o0b-bearing overlays / 61 SC07); 15/18 exemplar-matched. ⚠ CORRECTED by the T2 ×1 probe (R14): o0b-bearing ≠ o0b-adjacent — T85's 0x801457A4 banked by APPEND only because its address abuts the o0b object's END; the remaining families (0x8013Bxxx–0x8013Cxxx, below the whale) mis-place on append (probe: 1/1 gate-reject) and the alternative per-fn isolation IS the re-carve that trips Arm-A |
T2's real substance is the Arm-A +0x20 defect itself (first hypothesis: the re-carve lets splat re-GUESS a data-symbol boundary → pin the shifting symbol in the config and re-probe). The generalized driver (rollout_o0.py) stands as the sweep harness once placement works, and for any future adjacent case |
| Zero-crack roster (Lane A) | 114 families / 3,166 open members / ~204k weighted ins (28 substantial). The head of the roster IS the -O0 route set — T2 and Lane A open together |
Propagation-only fuel behind already-matched exemplars; the non-o0 tail is ~100 small families for family_sweep/dedup_extend as classed |
| Concentration | top-20 = 24.0% · top-100 = 44.8% of open family weight (1,587,311 ins) | Lane B works the head down; flatter than SESSION-13's 53% (the campaign consumed the head — expected) |
| Core queue (fresh worklist) | 101 live stubs / 261,789 gain-ins; GIANTs (func_801412A8 close=110, func_80178004 close=91) = 19.1% of it |
The stale 160/583k rows are gone; queue is oracle-derived |
| Instrument repairs shipped | gate_stage stage-0 + journal undo (§122) · rtu_match error surfacing · digests scope+HEAD-stamped · backlog scanner deleted (R33; 0 divergence vs corpus across 131 binaries) · 21-file include fix (R22 140/140) · autopsy refreshed | Every number above was produced AFTER the repairs (R35 sequencing) |
The opening play this frontier implies
- T0.5 prefetch batch (background): tail + main Ghidra-C — fuel for Lanes B/C and P31.
- T1 recovery sweep [Ultracode] over the 108 stranded MATCHes (+ the 10 named S16 drafts) — cheapest distinct wins, now through the stage-0-safe ladder.
- T2 the generalized o0b driver [Max]: ~9 non-jr route-ready
-O0families first (~950 members), then the jr+o0 composites (probe ×1 before ×136), then the 3 exemplar cracks; the 61 SC07 members and any re-carve-needed residue go to the wall ledger with evidence. - T3 lanes as planned — Lane A's non-o0 tail, Lane B down the concentration head, Lane C on prefetched seeds, Lane D (PINS 19 / W4 / permuter backlog).
