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.
