- condenser.rs: add recently_freed tombstone set (FREED_RECENCY_NS=5s).
unregister() stamps freed addresses; scan_and_compress() prunes stale
tombstones and skips any address within the recency window. Closes the
secondary address-reuse race: free(X) processed → malloc(X) re-registers
X → scan now skips X for 5s before treating it as a fresh allocation.
- membrane.rs: flip PIPELINE from test_mode:true → test_mode:false.
72h VPS stability check passed (no SIGBUS/SIGSEGV). Three-layer guard:
(1) 64K ring + deferred scan (#260) minimises unprocessed-free window;
(2) 60s burst gate blocks scan during startup coldload (original crash
window); (3) recently_freed tombstone closes the reuse race.

Condensate v2: Full Rust conversion — 12 modules, 105 tests, zero Python inflation
All four Condensate layers now in Rust:
Membrane — intercepts malloc/free system-wide (LD_PRELOAD)
Graph — learns causal access topology
Predictor — predicts next access from learned patterns
Condenser — compresses idle regions, pre-promotes on prediction
17 tests pass. Raw input, no classification — Law 7 for memory.
The substrate learns allocation patterns from pure observation.
