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
Tim Lingo	c2afcbddf5	fix(engram): allow SessionSummary node_type in validation allowlist ... handle_api_consolidate writes a "SessionSummary" node, but engram_valid_node_type omitted it — so once this validation ships, every consolidate() would be silently REJECTED at the engram boundary. Add SessionSummary to the allowlist. Found in Will's PR review of neuron #1 / el #52. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-10 06:26:25 -05:00
Tim Lingo	dfe4e83ed1	Fix engram_node_full wrapper field corruption + add node_type/tier validation ... The wrapper signature was stale and didn't match the C primitive __engram_node_full(content, node_type, label, salience, importance, confidence, tier, tags). Because el_val_t is an untyped machine word, the compiler coerced caller args to the wrong declared param types and forwarded them BY POSITION — so tier received an int, importance/confidence received strings, label received a float, etc. (~100 corrupt nodes). - Correct the wrapper to match the C contract 1:1 (no coercion, no reorder). - Add engram_valid_node_type / engram_valid_tier allowlists; engram_node and engram_node_full now reject invalid values with __println + return "" (fail loud, no silent malformed write). See neuron repo: HANDOFF-engram-write-corruption.md for the full write-up + deploy runbook. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-08 16:13:43 -05:00
