- two moves: delete `register s32 c40 __asm__("$3")` and its `c40 = 0x40;`, writing the literal at its four uses (byte-neutral
on its own — the pin was never doing the work); then swap the adjacent `f1e = 0x40;` and `f1a = 0x10;` so the 0x10 store
splits the run of 0x40 stores.
- the residual reads like cse/sched and the decision is local-alloc's. Dumps of the real TU in both orderings differ on one
.lreg line — `Register 76 used 5 times across 10 insns` -> `across 14 insns`, `Register 76 in 2.` -> `in 3.` — which is
find_free_reg's live-range scan at local-alloc.c:2109-2110: unswapped the two constants' ranges are disjoint and share $v0,
swapped they overlap and the first takes $v1.
- the $4 pin STAYS, and not as a lever: src/shared/ov/func_801687CC.h declares extern void func_80168828(void), so the
target's `move s1,a0` has no C source. An uninitialised local, a pointer-typed one, a split declaration and deleting it
outright all give the identical score-25 residual; both parameter forms are hard cc1 errors against that header. This is
the first measured pin that only a declaration fix can remove — one of the 51 conflicts P35 ledgered for the types phase.
The engine's score-1 text is a coincidence (its andi truncates garbage in $s1 and never reads $a0); not proposed.
- instrument fixed in the same change: --propagate refused all 124 siblings because the reshape deliberately keeps a lever.
The allowance is now derived from the exemplar's own banked text (its surviving !FAKE markers), and a sibling whose remap
would carry more levers than the exemplar is refused by name.
delever --propagate: 124 of 124 sibling(s) banked, 0 refused
- check-all: 218 passed, 0 failed of 218
lever_census --check: 29,572 pin/asm sites, 29,572 marked !FAKE, 0 UNMARKED — OK
- snapshot row 12; delever --selftest OK. The toolify (R16, the constant-run split) follows.
phase-ends/ — the living record
PhaseEnd_Phase[N].md— written at each phase boundary (format defined inPROJECT_CONTEXT.md). Append-only history: build log, deviations, commit message, rules added, changelog. Never deleted.CURRENT_PHASE.md— the in-phase autonomous log: approved phase plan, per-task checkboxes, current task pointer, blockers. Created at phase start, updated after every task, absorbed into the PhaseEnd file and deleted at phase close. This is the crash/compaction recovery point.DIGEST.md— the session-start digest: every phase's synopsis + every rule in full + the corrections to PROJECT_CONTEXT.md; appended at every PhaseEnd (P7).logs/Phase<N>.md— the archived in-phase worklogs (R19): NOT in the load order; consult on demand only.- Sessions read
PROJECT_CONTEXT.md, thenDIGEST.md, then the THREE most recentPhaseEnd_*.mdin numeric order, thenCURRENT_PHASE.md(if present), and replay its 🛑 SESSION CHECKPOINT block verbatim into the chat — every session (R64 candidate, 2026-09-05; ≈100k tokens + the checkpoint).
