will.anderson	59cea116c5	build(engram): rebuild binary with engram_load_merge runtime (deb0520) ... Runtime now includes engram_load_merge — soul daemon awareness.el calls this function during its periodic sync refresh cycle. Binary rebuilt from server.el (unchanged source) + updated el_runtime.c.	2026-06-30 08:59:01 -05:00
will.anderson	da116b2884	self-review 2026-06-30: WM cap, breakthrough floor, ISE exclusion + route ... Port critical WM fixes from self-review 2026-06-26 branch (f7bd99a) that were never merged to HEAD. Running binary had these fixes; source did not — rebuild would have silently regressed all three improvements. 1. ENGRAM_BREAKTHROUGH_WEIGHT 0.25→0.10 With 0.25, naturally-promoted nodes (threshold ≥0.15) decayed below the breakthrough floor within one activation call and lost their WM slot to fresh breakthrough candidates. All 524/525 WM nodes were at floor = useless. Invariant: BREAKTHROUGH_WEIGHT < min(type_thresholds = 0.15 Canonical). 2. ENGRAM_WM_CAP=24 with Pass 4 (per-call) + Pass 5 (global) enforcement Without cap, broad curiosity seeds promote 500+ nodes simultaneously. wm_avg_weight collapses, goal-bias differentiation is lost. Verified: "knowledge" query now promotes exactly 24 nodes (was 525). Cowan (2001) cognitive basis: WM capacity ~4 chunks; 24 allows rich multi-topic context. 3. ISE exclusion from WM (Pass 2 guard) InternalStateEvent JSON content ("knowledge", "memory", etc.) triggered lexical seeding → suppression accumulation → breakthrough at floor. ISEs are observability-only and must never surface in context compilation. suppression_count cleared so ISEs never build toward breakthrough. 4. route_create_ise importance fix (0.5→0.3) Corrects mismatch between HTTP route and awareness.el in-process fallback. Also adds body comment clarifying auth-exempt rationale. SYNAPSE (arXiv 2601.02744) validates WM cap design and ISE exclusion principle. Next priority: cosine similarity seeding to complement lexical BFS.	2026-06-30 08:48:19 -05:00
Will Anderson	6ced0f8009	fix: double-free in engram_neighbors_json BFS + rebuild engram.c ... el_strdup tracks pointers in the arena. The BFS arrays in engram_neighbors_json are manually freed — using el_strdup caused a double-free when the arena was later popped. Changed to plain strdup for those allocations. engram/dist/engram.c rebuilt from engram/src/server.el with current elc (minor codegen diff: parenthesisation and _argc/_argv rename).	2026-05-06 14:11:40 -05:00
Will Anderson	cd164debb8	add /nodes/list as alias for GET /nodes ... Dharma's EngramDB client calls /nodes/list to retrieve all nodes. Add this as an alias for the existing /nodes (and /api/nodes) route so downstream clients don't need to be updated when the API drifts. Also update dist/engram.c to match server.el.	2026-05-04 11:44:22 -05:00

Will Anderson	2b45fc2f0f	engram: runtime-native rewrite ... Engram is now a thin HTTP face over the El runtime's in-process graph store. The C runtime owns the data; engram_*_json builtins serialize results directly. There is no SQL, no SQLite, no db layer, no state machine — the runtime IS the database. src/server.el (348 lines, replacing 5797 lines across 15 legacy files): GET /health GET /api/stats POST /api/nodes (auth required) GET /api/nodes GET /api/nodes/:id DELETE /api/nodes/:id (auth required) POST /api/edges (auth required) GET /api/neighbors/:id POST /api/activate GET /api/activate POST /api/search GET /api/search POST /api/strengthen (auth required) POST /api/save (auth required) POST /api/load (auth required) Auth: ENGRAM_API_KEY in env. GET routes pass through (read-only). Mutating routes require {"_auth": "<key>"} in the JSON body until http_serve surfaces request headers and we can switch to Bearer. Persistence: engram_save / engram_load via JSON snapshot at $ENGRAM_DATA_DIR/snapshot.json. Loaded best-effort on startup. Build: dist/platform/elc src/server.el > dist/engram.c cc -std=c11 -O2 -I <runtime> -lcurl -lpthread -o dist/engram dist/engram.c <runtime>/el_runtime.c Live: native binary at dist/engram (113 KB), running under ~/Library/LaunchAgents/ai.neuron.engram.plist on :8742. Verified: GET /api/stats returns counts; POST /api/nodes with auth creates node with UUID; GET /api/search returns full node JSON; spreading activation returns hop-decayed strengths (0.8 × edge × decay per hop) with epistemic confidence filtering. Legacy (5797 lines of SQLite-era src) sealed at ~/Archives/engram-src-legacy-20260430.tar.gz and removed from disk.	2026-04-30 13:49:28 -05:00
