Wave 3 drew 1 target - 0 left in pool. Of 174 open: 64 main, and of 110 non-main, 41
drafted this session, 68 excluded, 2 walls, ZERO undrawn. Re-probing the 68 with
jtbl_carve --probe found 17 now reporting `tail`, because tonight's jr_isolate_all
fixes changed their overlays. All 17 already had drafts; 10 scored closeness 0 with no
drafting. The gate banked 5, and they are exactly the five overlays jr-isolated tonight.
An exclude list is a snapshot of what the TOOLING could not do and goes stale the moment
the tooling improves - re-probe it after every tool fix.
Two functions recorded as walls with their refutation lists rather than redrafted:
ov_SC03_105/func_801834A4 (loop.c movable ordering, closeness 6) and
ov_SC06_022/func_8017DF28 (expand_block_move's copy_addr_to_reg pseudo reused by cse,
closeness 2, seven levers measured inert). One MATCH blocked purely on carve state with
its exact prescription queued in .run/S71_carve_todo.txt.
Blocker census read off the 37 gate verdicts on disk: DIFF 18, CARVE 7, PARSE 3,
NO-DIAG 3, CONFLICT 2, ARITY 2, UNDEF 2. I had called carve the dominant remaining
class mid-session on the strength of the last two agents I'd read; it is not. What
remains is mostly genuine codegen, the opposite of the integration-dominated picture
this session opened with.
Also recorded rather than redrafted: ov_SC03_105/func_801834A4 as a proven loop.c
movable-ordering wall (closeness 6, two measured-inert levers), and
ov_SC01_004/func_8017EB30 as MATCH-279/279 blocked purely on §8e carve state.
Four new byte-proven levers from the overnight lane, none previously in the cookbook:
re-read the store instead of passing the value (CSE store-forwarding), (&SYM)[3] vs a
pointer local as an ADDRESSING choice, one biv with +0/+2/+4 for combine_givs, and a
local's width choosing lh vs lhu+sll/sra.
Also recorded: the same-address twin hint was false three times tonight (ov_SC06_000,
ov_SC01_080, ov_SC03_030) while the same-TU neighbour was the real fuel in every case.
Three of the night's five post-limit MATCHes recovered a body off disk rather than
re-deriving it - func_80181A60 in 2 minutes instead of 16.
All five in-flight agents died on the 5-hour limit and returned NO-DRAFT; that is a
harness kill, not a verdict about the targets (R40), so they relaunch unchanged.
Gate 5 banked 2 (commit:3614). launch_check.py added after a stale card burned an agent.
* Every pack carried PAST ATTEMPTS ON THIS EXACT FUNCTION, mined per-function from the
historical agent journals (52 of 60 targets, 131 notes). Every landed agent returned
MATCH at closeness 0 on the hardest frontier we have.
* §409 — the wave and the nine laws it produced. Law 1: a relocation-stream
TRANSPOSITION is invisible to match_one, the permuter scorer and every similarity
tier (HI16/LO16 masking; the §195-D blind spot for a different reloc class), and it
retroactively explains "MATCH but the gate rejected it" verdicts.
* §410 — COPY THEN ACCUMULATE ON THE COPY: satisfies the $s2 in-place destination and
the sched1 birthing boost at once, with the agent's measured refutation list.
* gate 1 (all 64 across 33 binaries): 12 banked — main 11 + ov_SC07_006 1.
* gate 2 tested "a bad draft kills its binary's good ones" by re-staging only the 25
that recover_integration --probe-only called MATCH in their real TU: 0 banked.
An honest null — that probe compiles and diffs bytes but never LINKS or CARVES,
so it is a third oracle with its own blind spot.
* triage (25/25 accounted): CARVE-REFUSED 10, undefined-reference 4, DIFF 3,
CC1-FAIL-no-diagnostic 2, PARSE 1; gate 1 adds 7 func-decl / 4 data-decl /
6 type-decl conflicts.
* R37 probe of the carve class: 6 of 8 are one refusal — a subseg would host
NON-CONTIGUOUS .rodata carves — whose named remedy is jr_isolate_all (§8b).
tools/restage_matching.py — rebuild a gate plan from probe verdicts.
tools/gate_triage.py — route a gate's verdicts to the lane each one names (R47).
The S70 patch was refused by its own adversarial review for sorting rows by recency:
a pair's ledger rows are several PROBES about one draft, alternating between
`closeness 4` and `won't compile standalone`, so max(ts) serves whichever probe ran
last — often the least informative. This form keeps both.
* the ts-newest verdict is still selected (file order made the per-binary bulk ledger
always win regardless of age: 25 pairs mis-selected),
* AND the best measurement ever taken on the pair rides alongside it, so a later
uninformative probe can no longer erase an earlier residual: 981 of 2,605 pairs
gain a line they were previously denied.
* BASELINE-RED is a fact about a binary at a moment (R51), frozen into an append-only
ledger and replayed forever — 2,676 rows all stamped 2026-08-26. gate_feedback now
reads the same live red union gate_stage consults, so a pack and the next gate run
cannot disagree: 173 expired claims retired, 0 binaries currently red.
R39 control 3/3 (expired-when-green, harness-line-when-red, measurement-survives).
* `git status --porcelain -- src/<binary>/` finds nothing for main, whose TUs are
src/800.c, src/boot.c, ... — so a main worker returned `files: {}` while the bank
oracle (the stub disappeared) still counted the banks. parallel_gate printed
"12 banked across 2 binaries" and committed one of them.
* src_scope() takes the scope from the binary's own stub rows (each names its TU),
captured BEFORE the gate because a bank deletes the stub that names it, and keeps
the directory prefix for overlays that have one.
Negative control: main 0 -> 54 TUs, ov_SC07_006 1 -> 3 (superset, no regression).
* A reused worktree kept the previous job's .run/harvest_failed*.classified.txt, so
verdicts surfaced under the wrong binary; the worker clears them first.
* tools/gate_triage.py — routes a gate's verdicts to the repair lane each names (R47),
with the staged-draft denominator asserted (R32/R41).
Re-gated main: 11 banked (commit:3586), main real frontier 64 -> 53.
* `binof = {c["fn"]: c["binary"]}` was last-writer-wins, and `status`, `det` and `subof`
had the same shape — a draft of a name carried by two binaries was stamped with
whichever card came last and then reloc-checked against the OTHER binary's symbols.
* Resolve per draft instead: the shard's own target list first
(`.run/wave_<tag>_targets.<i>.json` = `targets[i::workers]`, each row carrying its
binary), a unique-name card second, a counted refusal when neither can answer (R43).
* R39 negative control over every historical wave: 42,655 drafts, 0 regressions,
2,317 (5.4%) previously mis-stamped; 2,107 homonym card names fleet-wide.
Intra-shard ambiguity: 0 of 50,684 (shard, name) pairs over 302,370 shard files.
docs: §408 — §406 refuted as a sweep (0 MATCH / 14 applied, 0 / 210). The 134-member
census counted main's 960 LINKED library stubs and matched a symmetric SHAPE; derived
from the mine-vs-target residual the addressable set is 15 / 210. Decision-log entry
records the pivot: 64 of 210 (30.5%) already match standalone, so the frontier's
largest lane is §376 integration, not codegen.
tools/weave_sweep.py — the derived-selector sweep (R32 coverage, R41 denominators,
--lever-all ablation control).
- ran residual_rules_b over the WHOLE open frontier (1,312 cases, 0 errors, ~2min, $0)
instead of a 50-row sample; artifacts in .run/S70_*
- DENOMINATOR (Drew's correction, R41): main's 960 PsyQ LINKED stubs are not
matching targets; true frontier = 355 (67 main REAL + 288 non-main), partitioned
with progress.linked_subsegs() rather than a hand-rolled filter (R33)
- discriminating test settles population-vs-coverage: fire rate DOES rise as
residuals get clean (35.3% at <=8 vs 6.1% at >64) but 57% of the cleanest band
is still UNKNOWN -> coverage binds where rules are worth writing
- hand-label 4/4 labelable to existing cookbook buckets; WIDTH/lhu!=lh has its
discriminating sig already computed and still returns top=None
- 86 REAL standalone MATCHES (closeness 0) = 24% of the frontier, blocked on TU
plumbing only -- outranks the rule work (standalone-match-is-not-bankable)
- logs 4 instrument defects in my own probe, incl. one wrong answer reported to
Drew before checking: 4 of S68's 10 autodecl MATCH drafts are STILL OPEN
- tools/r22_verify.sh from a clean tree: clean rc=0, extract-all 212+main rc=0,
check-all 213 passed / 0 failed of 213 (2m49s). Clears the S69 --no-r22 debt.
- R38 read of the recorded measurement behind the "1-2% ceiling" (S68 eval set +
.run/rules_b/eval_results.jsonl) before designing the queued probe:
* citation fix: the design is Fable-1 (.run/S69_fable/report.md:93), not Fable-2 §7.7
* denominator fix (R41): shape rules can only fire on the 39 near rows, not 113;
real fire rate 3/39 = 7.7% (5/39 with REDRAFT), and 14 are UNKNOWN
* the probe as written is unrunnable: backlog has 125 rows / 20 with residual text
and the UNKNOWN pile is 14 -- sampling 50 would report a narrower world (R41/R32)
The 'false bank' in the S69 checkpoint was not one. Both instances verify
byte-identical after 'make extract BINARY=<b>'. §384 states the law (verification
must regenerate whatever the gate changed the inputs to), the trap inside it (a
src-only revert of a carve commit produces 'table-count drift vs the carve', which
reads like progress), and the give-away I ignored — the commit diffstat showed
config/overlays.mk and a splat yaml sitting next to the .c.
The third fable escalation did NOT close its function (main/func_8001BC6C,
33 -> 28 over ~45 measured compiles), so the checkpoint's '2 for 2' is corrected
to 2 closed of 3. The failure is banked because a negative result that tells
future agents when to STOP is worth its tokens.
THE BOUND: sched.c schedule_select ALWAYS fronts a ready load over an
equal-priority ALU leaf (potential_hazard), so no C spelling can emit an ALU chain
before loads that are simultaneously-ready same-priority leaves. If a target shows
that order, look for reorg slot-steals, hard-reg dependency walls, or late in-block
consumers BEFORE burning compiles on statement permutations.
Also banked: the reorg fill_simple_delay_slots slot-steal diagnostic and its
split-tree precondition (the accumulator must live outside the $v0-heavy tail to
be eligible), three supporting levers, and three REFUTED ones with measurements --
a dead-init boost-kill is a no-op because cse delete_dead_from_cse removes it
before the final reg_scan, dense-block re-ties cost +4 to +9 because each re-tie
re-anchors its own load, and the -fno-schedule-insns oracle does not discriminate
when the residual is a multi-pass composition.
This run applied §361 CORRECTLY -- it removed the prior agent's pin first and
exonerated it for the head -- which is why its four-pass diagnosis can be trusted
where the previous single-tie claim could not.
The S67 FINAL-3 OPEN item, plus the two defects found while doing it.
* fix(dedup_propagate): the tool could not run AT ALL. S67's -j patch wrote
`os.environ` at module level in the one module that imports `os as _os`, so
every invocation died with NameError before doing any work. Propagation was
not deferred, it was impossible. Import-checked the other 7 -j-patched tools.
* propagation, honestly scoped: the real closable set is 11, not 32, derived two
independent ways that agree (seed_ref exact+same_addr, and a direct corpus
derivation). The 3,161-entry --auto-from plan over 53 overlays is dedup
hygiene over already-matched code and closes almost no open stub.
Applied: 2 banked byte-green (ov_SC04_018 func_80181270, func_80182AF8);
3 gate-refused and cleanly reverted; 6 blocked with named blockers
(3 CARRY-FIXABLE, 3 func_80144B9C not-inline-def -> needs the o0 whale carve).
R22 clean fleet: extract 212/212, check 213 passed 0 failed of 213, rc 0/0/0.
Frontier 453 -> 451.
* fix(seed_ref): REFUSE targets in LINKED subsegs. The playbook calls this tool
"the fleet-wide answer" and it reported 82 open stubs with a banked twin --
43 of them main stubs whose TUs the linker script never references. Any C
written there compiles, links and leaves the SHA1 green WHETHER OR NOT IT IS
CORRECT, so a mechanical twin lane fed from that list could have minted up to
43 gate-green FALSE matches the byte gate cannot see. draw_waves has refused
these since S66; this oracle did not. The refusal is counted and printed, not
silent. NC: guarded 39 subset of raw 82, all 43 dropped are main, the non-main
population is identical.
* wave drawn: .run/S68o1 (24 opus 187-770 ins) + .run/S68m1 (30 main), cards +
packs + wave_args asserted, queue of 53. Drafting opened at concurrency 5.
Written after the last harvest, per the rule that the checkpoint is always last. Supersedes the
interim S66 block. Machine quiesced, tree clean at commit:3350.
Leads with the three things a fresh session must not re-learn: main is ~94 open not 1,099 (and
drafting into a LINKED subseg would gate GREEN while wrong); the family era is over so integration
is the whole game (147 of 591 open fns already had byte-correct drafts stranded on four blockers);
and 'independent' means a different INSTRUMENT — two refusals from parallel_gate were one instrument
twice, after which the serial gate banked 16/32 of that class.
Also records that ~56 of the 416 banks came from ZERO drafting agents, purely from work already on
disk, and Drew's binding harvest-then-toolify-before-the-next-wave rule.
Written for a fresh session. Headlines: main is ~100 open not 1,099 (960 stubs are LINKED dead text,
and drafting into them would gate GREEN while wrong); families are spent (84-93% singletons, twin
pool dry); integration is now the whole game (147 of 591 open fns already had byte-correct drafts
stranded on four blockers). Records Drew's binding rule — harvest, then toolify, BEFORE the next
wave — and the F18 retraction: two refusals from parallel_gate were one instrument twice, not two
independent tests; the serial gate then banked 16/32 of that class.
CURRENT_PHASE.md now holds 27 checkpoint blocks and several older ones say 'supersedes every earlier
block' — true when written, false now. The S64 FINAL block sits ~370 lines above the live S65 FINAL-4
one and makes the same claim, so a fresh session reading top-down could anchor on a state the tree has
moved past by 647 banked functions. Banner at the top states the rule: the LAST block is the live one.
