P9-T1: create CURRENT_PHASE.md as the phase ledger; baseline revalidated
clean (cmp + SHA-1 e173426c157384ebf1b6caf8c6fea18a85a14af9, make check
regions=158 disagreements=0 c_regions=158 MATCH); three workers probed and
recruited (01a0d180-ea72/-efdd/-f513); 3-way partitions generated and proved
disjoint (3x575 rows, pairwise intersections 0, union == worklist).
P9-T2 (tooling half): promote worker B's scratch instruction diff into
tools/sf3_diff, hardened per the plan: PS-X LOAD read from the header,
objdump path derived from the repo, temp files under the caller's work dir,
resolver printing ready-to-paste symbol names. 17 synthetic tests.
sf3_triage: new counted exclusion excluded_delay_slot_start=5, implemented
after independent verification of worker B's finding (a branch/jump always
executes its delay slot, so no function starts at X+4; 0 of 158 registered
regions does). Worklist regenerated: 1725 eligible rows, tiers 355/1365/5.
3 new synthetic tests; existing triage fixture extended.
