self-review 2026-07-25: short-term inhibition-of-return + explicit embedding backfill

Working memory was winner-take-all: suppression_count never entered the promotion score and was reset on promotion, so two high-salience nodes pinned a saturated 24-slot WM for hours. Add Lebiere-Best (CogSci 2009) short-term inhibition — raw_wm *= t_n/(t_n + 120s) from the most recent recorded access — producing emergent round-robin over WM candidates. embedded_count stalled at 93/12175 after restart: the lazy backfill only runs inside engram_activate, which nothing calls on the authoritative store in production, and in-RAM vectors were never snapshotted. Add engram_embed_backfill(n) + GET/POST /api/embed-backfill route that persists the canonical snapshot whenever it embeds anything; the soul heartbeat pumps it at 32/min.
