audit: harvest-sweep cycle close — C29 forward-pointers lifted to shipped state

Architect drift review (range 7cc3ce0..HEAD): holds confirmed — C27
unbound-inert intact (the #334 note is C14's promised benign class,
structurally dead under record-all); #326's exit-1 matches C14's
class-1 wording and the pinned #175 attribution family; C29 discipline
moved with the FoldSchema retirement (registry roster doc-gated +
prose pinned against the executable rules); commit bodies substantiate
against the diff.

Drift resolved: [medium] C29's closing forward-pointers still described
#315 rendering as pending, #267 as upcoming, and a fold introspection
surface as blocked on #310 — all shipped/retired; updated to the shipped
state including the #332 registry-roster form. [low] the runner-side
eprintln register family grew by the note and the roster-carrying
refusal — tracked forward on #297 (scope comment there), consistent
with the C14 tension already routed in the #310 audit.

Regression check (aura-bench, report-only): all five fingerprints OK.
engine_throughput 14002097 bars/s (-0.0%), ingest 12982397 (-0.1%),
campaign_sweep wall 1.402s (+0.5%), campaign_heavy wall 5.588s (+0.3%,
peak_rss +7.7%), cli_fixed_cost help 1.7ms (+11.4% NOTICE) — the NOTICE
and rss delta measured at loadavg 8.9 with a parallel build running;
sub-2ms jitter, not ratified as a real move (no baseline change;
harness is report-only).

Erratum to 8dbca82's body: the blast-radius corpus is 24 committed
*.ops.json files, not 21 (all verified building; the count was
understated).
