The 26-A audit named difficulty's 136-entry BINARIES dict as the exact root cause corpus.py:9
describes (a hand-maintained allowlist over a filesystem that already answers the question), and
exemplar_miner's registered_addrs() as a ~60%-wrong proxy for "is this still work?". T7 onboards
new overlays, so these are migrated FIRST or the new binaries silently miss make report.
- exemplar_miner.py: "still a residual?" now = corpus.stubs(source) membership (the INCLUDE_ASM
invariant, R33), not dp.registered_addrs() (config/dedup.us.yaml — a matched-but-unregistered
fn, e.g. banked inline or matched-but-local, stayed wrongly in the residual pool).
- difficulty.py: the 136-entry hand-dict -> cfg_for(alias), deriving the mechanical layout
(src/<a> + asm/<a>/nonmatchings; main/resident the two specials). Validated against the tree
(src/<a> must exist -> a typo is a clean error, R32), not a hand-list. A newly-onboarded overlay
now needs zero difficulty registration.
- new_overlay.sh: DROPPED difficulty from the sentinel-insertion set (T6 made it obsolete; leaving
it would insert a dead dict entry into a file that no longer has a dict). The other 3 tools
(diff_settings/progress/dup_report) keep their hand-lists — migrated one-at-a-time, byte-gated,
per the audit's cadence; NOT dup_report.BINARIES, which corpus depends on as the binary list.
VERIFIED:
- difficulty derivation is BYTE-EXACT vs the old dict for all 136 aliases (0 mismatches), and
old-tool vs new-tool output is byte-identical (.md AND .csv) on the same tree — the diff vs the
committed docs was pure staleness (committed 2026-06-20, tree at 2026-07-15), NOT my change (R14).
- unknown alias -> clean error, not silent-empty output.
- exemplar_miner runs -> 223 residual stubs (corrected; it's a manual tool, not in make report).
- new_overlay.sh: bash + embedded-python both parse; difficulty absent from the insertion set.
- onboarded all 118 not-yet-onboarded overlays via tools/new_overlay.sh (0 failed)
-> fleet = 134 location overlays + main + resident = 136 binaries
- R22 CLEAN rebuild (make clean -> extract all 136 -> make check-all):
136 passed, 0 failed of 136 -- every overlay byte-identical at 100% INCLUDE_ASM
from a fully clean tree, 0 extract failures
- per-overlay config (splat.ov_*.yaml / check.ov_*.sha / symbols.ov_*.txt) +
config/overlays.mk var blocks + the 4 report/diff BINARIES dicts auto-registered
(sentinel-anchored, idempotent); src/ov_*/ stub records committed (harvest_verify
reverts via git checkout, so the records must be tracked before any harvest)
- ghidra/ churn NOT staged (R23); build/asm/assets/.run gitignored
- report-digest regen (fleet-wide duplicates.cross.md + progress.fleet.md) is T4
- onboarded ov_{SC01_000,SC01_001,SC02_000,SC02_003,SC03_002,SC03_006,
SC04_000,SC04_018,SC04_019,SC05_000,SC06_000,SC07_000} via tools/new_overlay.sh
— spans all 7 SC areas + 2 full duplicate pairs (SC02_000≡003, SC04_018≡019)
- each byte-identical at 100% INCLUDE_ASM (non-4-aligned auto-handled); no
position-lock anomalies — the cross-shape risk is retired before the full onboard
- make check-all = 18/18 passed (main + resident + 4 prior + 12 new)
- config/overlays.mk + 4 report dicts auto-registered (sentinel, idempotent)
- ghidra/ DB churn NOT staged (R23); asm/build/assets/.run gitignored
- diff_settings.py + progress.py/difficulty.py/dup_report.py: add the `resident` BINARIES entry
(build/resident/, config/check.resident.sha, src/resident, asm/resident/nonmatchings, per-binary docs)
- dup_report.py: degrade gracefully when the Ghidra sig (.run/sig.resident.jsonl) is absent —
write a placeholder + exit 0 instead of crashing the whole `make report` (sig is a T4 export)
- progress.py: scope linked_subsegs() to BINARY==main — PsyQ library linking is the EXE's layout
(Phase 8, gated ifeq BINARY,main), so a second binary has 0 LINKED (was: listed main's libs)
- Makefile expected: per-binary-safe — drop `rm -rf expected/build` (clobbered every sibling
baseline); refresh only the active binary's image dir + merge-copy (cp never deletes siblings)
- reports: resident = 0 REAL / 143 INCLUDE_ASM stubs / 100% stub (correct); main UNCHANGED
(52 REAL / 959 LINKED / 50.24%); both expected/ baselines coexist (verified)
