will.anderson	9a0266cbf9	engram tiered storage M3.5: persist activation field updates (pre-flip gate) ... Flag-on checkpoint now full-walks the resident graph: store_put_node (WM weight, activation_count, last_activated, wm_anchor) + store_put_edge (hebb, last_fired) for every node/edge, then engram_checkpoint. Uses store_put_edge (idempotent upsert) not store_hebb_batch, because activation FORMS new hebbian-associate edges that bypass the create hook and delta-only hebb_batch can't create them. Store-on boot now applies the same WM-halving + floor + cap transforms as engram_load. This is the hebb-survives-restart fix. Gate: reboot from neuron.egm with snapshot.json deleted -> edge hebb + activation_count survive unchanged, WM weight survives with identical boot transform; negative control proves persist is load-bearing (hebb->0 without it). M1 33/33 + M2 36/36 + M3 parity PASS, ASan/UBSan clean, flag-off untouched. Engine unchanged (boundary held).	2026-08-11 23:37:52 -05:00
will.anderson	a72145b44e	engram tiered storage M3: wire store behind ENGRAM_STORE (default off) + .egm rename ... Caller-side shim in el_runtime.c maps EngramNode/Edge <-> StoreNode/Edge; engine keeps zero soul deps (libengram boundary, design §10). Flag off = today's JSON path byte-for-byte (proven: no neuron.egm created, graph identical). Flag on = engram_open (import snapshot.json once into neuron.egm, else WAL-replay) + resident load; node/edge create + forget dual-write via guarded hooks. Files renamed engram.store->neuron.egm, engram.wal->neuron.wal. Gate: M3 parity PASS (graph on==off byte-exact modulo ordering; snapshot round-trip; reboot-from-egm with snapshot.json deleted; activation set+sequence identical; ASan/UBSan clean). M1 33/33 + M2 36/36 green post-rename. Known gap (pre-flip): in-place hebb/WM/activation_count updates during activation are not yet persisted to the store (create/connect/forget are). Must close before live flip so learned edges survive restart.	2026-08-11 23:21:21 -05:00
will.anderson	8affb1d6e0	engram tiered storage M2: WAL + checkpoint + crash recovery + legacy import ... Write-back no-steal buffer pool makes the fsync'd WAL load-bearing (M1 was write-through). Logical WAL with record-granularity page-LSN redo idempotency. Checkpoint = flush dirty pages, fsync store, advance last_checkpoint_lsn, reclaim WAL prefix. One-time snapshot.json import only when store absent; JSON never read as the ongoing store thereafter. Gates: 33/33 M1 (no regression) + 36/36 M2 — replay parity, torn-tail fuzz (every byte offset), checkpoint-crash at all 5 phases, torn-page+WAL redo, legacy-import parity, hebb-survives-crash.	2026-08-11 23:00:20 -05:00
will.anderson	fa47b98d18	engram tiered storage M1: on-disk paged store format + round-trip tests ... Self-contained paged store (lang/runtime/engram_store.{c,h}): 16KiB slotted pages, u32 TLV self-describing records (forward-compatible), overflow chains, B+-tree id-index + from/to adjacency, page free-list, tombstones, double superblock + crc recovery. Not yet wired to activation (M3). 33/33 tests pass (ASan/UBSan clean); 5k nodes/20k edges round-trip bit-exact incl 768xf32 emb + hebb; store 25MB vs 64MB JSON. Format is final — see design §2.4.	2026-08-11 22:26:05 -05:00
will.anderson	0a72fced28	engram: WAL persistence + integrity hardening + single canonical runtime ... Establish lang/runtime/ as the ONE canonical el runtime (from the active runtime that carries hebb/emb persistence + the new WAL); repoint the el CI publish, engram build, elb default, and in-repo build scripts to it; delete the el-compiler/runtime + lang/releases/ forks; add scripts/check-single-runtime.sh drift guard. Fixes a live prod bug: the el CI published el-runtime-c/-h from the LAGGING el-compiler fork (0 hebb refs), so the shipped soul never persisted Hebbian edge weights — learned co-activation was wiped on every restart. Publishing from canonical ships the stranded 'learning that cannot outlive the process' fix. WAL storage engine + integrity fixes (DELETE->tombstone + store-layer protection, safe data-dir default) ride in behind ENGRAM_WAL (default off = byte-identical to today). Verified: engram elb per-module build clean, WAL gate 66/66, native smoke ok, drift-guard green.	2026-08-11 21:31:37 -05:00
