The SESSION-20 carry item ("promote it — it closes 3 of the 4 blindness classes"), generalized:
base vram DERIVED from the target .s (was hard-coded to one function, R33) and the parse
coverage-asserted (R32 — a target that parses to zero instructions refuses to report a verdict
rather than reading "ALL RESOLVED"). Resolves jal callees, %hi/%lo data addresses (recovering the
implicit REL addend objdump -r never prints — the §84 trap) and internal j destinations.
IT TOOK TWO OF ITS OWN BUGS TO TRUST IT — both found by cross-checking masked_diff (R34):
1. `objdump -dr` instead of `-drz`: without -z objdump ELIDES identical-instruction runs, so
func_801330E0 read 104 ins vs masked_diff's 110 (6 elided nops) and every later index compared
against the wrong instruction — 2 phantom mismatches on a clean draft. A comparison tool MUST
share its reference oracle's index space exactly.
2. the .s word field is little-endian HEX TEXT, not the instruction integer; masked_diff byte-swaps
it and this did not — reporting "word differs" on three byte-IDENTICAL sites.
Now classifies instead of alarming: JTBL (gcc emits its own switch table via a local label => nothing
to relocate; the §81 routing signal — bank via jtbl_family_bank, never plain harvest_verify) ·
BAKED-LITERAL (same constant materialized inline: byte-correct here, but if the symbol is
per-overlay the exemplar matches and every SIBLING breaks — the §84 shape) · real mismatch.
Recorded: measuring a live wave's drafts is itself the §87 staleness error — a draft rewritten 12s
before the check gave a different verdict. Draft QA happens after the wave returns.
(The wave's gate driver lives at .run/s21_gate.py — gitignored scratch, §55b orchestration law
built in: --no-propagate per TU group, commit before the fleet propagate, and BANKED derived from
the stub set rather than read from gate_stage's accumulating verified-file.)
