The release notes are the one surface with no gate: two defects reached the tag candidate, both found by hand

mutation_survey has no 'retired' state — a site legitimately eliminated by a fix can only be deleted (shrinking the sample silently) or redden CI forever

vcr_dec_001_graph_alloc_differential.py hand-mirrors the frozen codegen anchors — one went stale and reddened main for five merges

RV32: constant memory addresses are folded into the 12-bit load/store immediate — blocks 13/13 gale thin drivers

Status: Open.

status_evidence: an artifact whose work SHIPPED can stay proposed — R3 cannot see manual: done-when, R4's subject convention no longer matches, R10 passes anyway

CI floor regex [4-9][0-9]* means "first digit 4-9", not "at least 4" — the mutation-survey gate reddens when the pinned subset GROWS past 9

optimized path: an i64 NON-PARAM local loses its value on the default self-contained image — aarch64_locals_851:i64_local returns 1, brif_local_zeroinit_990:bl_brif_i64 returns the high half in both words, i64_width_vstack_946:f_brif returns 0 — each with R9/R10/R11 clobbered (#1204's pair class?), exit 0

Status: Open.

· avrabe opened on Sep 9, 2026

optimized path: i64.clz / i64.ctz / i64.popcnt leave the HIGH word uncleared (hi = the input's high word) on the default self-contained image, exit 0 — direct selector correct (the #916 class on the other selector)

Status: Open.

mutation survey: DEAD means unreached by a soft-float, flag-off corpus — all four v0.65 DEAD sites are reachable (RQ-66-DELETE)

Status: Open.

varve: the pulseengine rolling root rotated and the registry moved — pin and realms file must move together

Status: Open.

aarch64 selector: operand-class confusion — 'local.set: expected GP operand, got FP' / 'fcompare: expected FP operand, got GP' across the float MVP-core files

VCR-RA-003 refuses its own emitted stream on spec modules: JoinValueNotAvailable { reg: R4 } on br/br_if/br_table/labels (+ an R5 instance) — a caught would-be miscompile
