Introduce two trait boundaries that the rest of the stack now sits above,
landing Phase 1 of ADR 0001 (pluggable storage and network access).
Rebased onto v2.1.22 Sanhedrin from the original April work.
MemoryStore / LocalMemoryStore (crates/vestige-core/src/storage/memory_store.rs):
One trait, ~25 methods, covering CRUD, hybrid / FTS / vector search,
FSRS scheduling, graph edges, and the forthcoming domain surface.
trait_variant::make generates a Send-bound MemoryStore alias over the
base LocalMemoryStore so Arc<dyn MemoryStore> works under tokio/axum.
Storage errors map through a dedicated MemoryStoreError.
Embedder / LocalEmbedder (crates/vestige-core/src/embedder/):
Pluggable text-to-vector encoder. FastembedEmbedder wraps the existing
EmbeddingService; storage never calls fastembed directly anymore.
Embedder::signature() produces the ModelSignature consumed by the
store's embedding_model registry.
SqliteMemoryStore (crates/vestige-core/src/storage/sqlite.rs):
Storage renamed to SqliteMemoryStore; the old name lives on as a
pub type alias so Arc<Storage> consumers in vestige-mcp stay intact.
All existing inherent methods are untouched; the trait impl is
purely additive and dispatches into them. The db_path field added
by v2.1.1 portable-sync is preserved.
Migration V14 (crates/vestige-core/src/storage/migrations.rs):
Renumbered from V12 (the original April number) to V14 to slot in
cleanly after upstream's V12 (v2.1.1 sync_tombstones) and V13
(v2.1.2 purge tombstones).
- embedding_model registry table (CHECK id = 1, code enforces the
single-row invariant).
- knowledge_nodes.domains / domain_scores TEXT columns (JSON arrays
default '[]' / '{}'), domains catalogue table, supporting indexes.
Phase 4 populates these columns; Phase 1 just exposes the schema.
Consolidation and other cognitive pathways now accept a
&dyn LocalMemoryStore (sync) or Arc<dyn MemoryStore> (async) rather
than a concrete Storage.
Tests:
- trait-method unit tests colocated in sqlite.rs and migrations.rs
- embedder/fastembed.rs tests for name/dimension/hash stability
- new integration crate tests/phase_1 (added to workspace members):
trait_round_trip (8), embedding_model_registry (7),
domain_column_migration (5), cognitive_module_isolation (4),
send_bound_variant (2), embedder_trait (2).
Acceptance gate post-rebase:
- cargo build --workspace --all-targets: ok
- cargo clippy --workspace --all-targets -- -D warnings: clean
- cargo test -p vestige-core --lib: 428 pass
- cargo test -p vestige-phase-1-tests: 28 pass
- cargo test -p vestige-mcp --lib: 380 pass (Storage alias preserves
every existing call site)
Co-existence with v2.1.1 portable-sync: this trait extraction is
additive. Portable-sync's tombstone migrations (V12, V13) remain
on the concrete SqliteMemoryStore; Phase 2 (Postgres) will decide
which of those surfaces graduate into the trait.
First AI memory system to model forgetting as a neuroscience-grounded
PROCESS rather than passive decay. Adds the `suppress` MCP tool (#24),
Rac1 cascade worker, migration V10, and dashboard forgetting indicators.
Based on:
- Anderson, Hanslmayr & Quaegebeur (2025), Nat Rev Neurosci — right
lateral PFC as the domain-general inhibitory controller; SIF
compounds with each stopping attempt.
- Cervantes-Sandoval et al. (2020), Front Cell Neurosci PMC7477079 —
Rac1 GTPase as the active synaptic destabilization mechanism.
What's new:
* `suppress` MCP tool — each call compounds `suppression_count` and
subtracts a `0.15 × count` penalty (saturating at 80%) from
retrieval scores during hybrid search. Distinct from delete
(removes) and demote (one-shot).
* Rac1 cascade worker — background sweep piggybacks the 6h
consolidation loop, walks `memory_connections` edges from
recently-suppressed seeds, applies attenuated FSRS decay to
co-activated neighbors. You don't just forget Jake — you fade
the café, the roommate, the birthday.
* 24h labile window — reversible via `suppress({id, reverse: true})`
within 24 hours. Matches Nader reconsolidation semantics.
* Migration V10 — additive-only (`suppression_count`, `suppressed_at`
+ partial indices). All v2.0.x DBs upgrade seamlessly on first launch.
* Dashboard: `ForgettingIndicator.svelte` pulses when suppressions
are active. 3D graph nodes dim to 20% opacity when suppressed.
New WebSocket events: `MemorySuppressed`, `MemoryUnsuppressed`,
`Rac1CascadeSwept`. Heartbeat carries `suppressed_count`.
* Search pipeline: SIF penalty inserted into the accessibility stage
so it stacks on top of passive FSRS decay.
* Tool count bumped 23 → 24. Cognitive modules 29 → 30.
Memories persist — they are INHIBITED, not erased. `memory.get(id)`
returns full content through any number of suppressions. The 24h
labile window is a grace period for regret.
Also fixes issue #31 (dashboard graph view buggy) as a companion UI
bug discovered during the v2.0.5 audit cycle:
* Root cause: node glow `SpriteMaterial` had no `map`, so
`THREE.Sprite` rendered as a solid-coloured 1×1 plane. Additive
blending + `UnrealBloomPass(0.8, 0.4, 0.85)` amplified the square
edges into hard-edged glowing cubes.
* Fix: shared 128×128 radial-gradient `CanvasTexture` singleton used
as the sprite map. Retuned bloom to `(0.55, 0.6, 0.2)`. Halved fog
density (0.008 → 0.0035). Edges bumped from dark navy `0x4a4a7a`
to brand violet `0x8b5cf6` with higher opacity. Added explicit
`scene.background` and a 2000-point starfield for depth.
* 21 regression tests added in `ui-fixes.test.ts` locking every
invariant in (shared texture singleton, depthWrite:false, scale
×6, bloom magic numbers via source regex, starfield presence).
Tests: 1,284 Rust (+47) + 171 Vitest (+21) = 1,455 total, 0 failed
Clippy: clean across all targets, zero warnings
Release binary: 22.6MB, `cargo build --release -p vestige-mcp` green
Versions: workspace aligned at 2.0.5 across all 6 crates/packages
Closes#31
FSRS-6 spaced repetition, spreading activation, synaptic tagging,
hippocampal indexing, and 130 years of memory research.
