0. Executive Summary (60-second read)

Vestige is a Rust-based MCP (Model Context Protocol) cognitive memory server that gives any AI agent persistent, structured, scientifically-grounded memory. It ships three binaries (vestige-mcp, vestige, vestige-restore), a 3D SvelteKit dashboard embedded into the binary, and is distributed via GitHub releases + npm. As of v2.0.7 "Visible" (tagged 2026-04-19), it has 24 MCP tools, 29 cognitive modules implementing real neuroscience (FSRS-6 spaced repetition, synaptic tagging, hippocampal indexing, spreading activation, reconsolidation, Anderson 2025 suppression-induced forgetting, Rac1 cascade decay), 1,292 Rust tests, 251 dashboard tests (80 just added for v2.0.8 colour-mode), and 402 GitHub stars. AGPL-3.0.

The branch feat/v2.0.8-memory-state-colors was fast-forwarded into main tonight adding the FSRS memory-state colour mode, a floating legend, ruthless unit coverage, the Rust 1.95 clippy-compat fix (12 sites), and the dark-glass-pill label redesign. CI on main: all 4 jobs ✅.

The next six releases are scoped: v2.1 "Decide" (Qwen3 embeddings, in-flight on feat/v2.1.0-qwen3-embed), v2.2 "Pulse" (subconscious cross-pollination — the viral moment), v2.3 "Rewind" (temporal slider + pin), v2.4 "Empathy" (emotional/frustration tagging, first Pro-tier gate candidate), v2.5 "Grip" (neuro-feedback cluster gestures), v2.6 "Remote" (vestige-cloud upgrade from 5→24 MCP tools + Streamable HTTP). v3.0 "Branch" reserves CoW memory branching and multi-tenant SaaS.

Sam's context (load-bearing for any strategic advice): no steady income since March 2026, Mays Business School deadline May 1 ($400K+ prizes), Orbit Wars Kaggle deadline June 23 ($5K × top 10), graduation June 13. Viral OSS growth comes first; paid tier gates second.

1. What Vestige Is

1.1 Mission

Give any AI agent that speaks MCP a long-term memory and a reasoning co-processor that survives session boundaries, with retrieval ranked by scientifically-validated decay and strengthening rules — not a vector database with a nice coat of paint.

1.2 Positioning vs. the competitive landscape

System	Vestige's angle
Zep, Cognee, Letta, claude-mem, MemPalace, HippoRAG	Vestige is local-first + MCP-native + neuroscience-grounded. The others are cloud-first (Zep/Cognee), RAG-wrappers (HippoRAG), or toy (claude-mem). Vestige is the only one that implements 29 stateful cognitive modules.
ChatGPT memory, Cursor memory	Both are opaque key-value caches owned by their vendor. Vestige is open source and the memory is yours.
Plain vector DBs (Chroma, Qdrant)	They retrieve by similarity. Vestige rewires the graph on access (testing effect), decays with FSRS-6, competes retrievals, and dreams between sessions.

1.3 The "Oh My God" surface

1. The 3D graph that animates in real-time when memories are created, promoted, suppressed, or cascade-decayed.
2. The dream() tool that runs a 5-stage consolidation cycle and generates insights from cross-cluster replay.
3. deep_reference — an 8-stage cognitive reasoning pipeline with FSRS trust scoring, intent classification, contradiction analysis, and a pre-built reasoning chain. Not just retrieval — actual reasoning.
4. Active forgetting (v2.0.5 "Intentional Amnesia") — top-down inhibitory control with Rac1 cascade that spreads over 72h, reversible within a 24h labile window.
5. Cross-IDE persistence. Fix a bug in VS Code, open the project in Xcode, the agent remembers.

CI on HEAD	All 4 jobs ✅ (Test macos, Test ubuntu, Release aarch64-darwin, Release x86_64-linux)

1.5 License

AGPL-3.0-only (copyleft). If you run a modified Vestige as a network service, you must open-source your modifications. This is intentional — it protects against extract-and-host competitors while allowing a future commercial-license path for SaaS (Part 9.7).

3. vestige-core — Cognitive Engine

3.1 Purpose

Library crate. Owns the entire cognitive engine: storage, FTS5, vector search, FSRS-6, embeddings, and the 29 cognitive modules. Has no knowledge of MCP, HTTP, or the dashboard — those live one crate up.

3.2 Metadata

name = "vestige-core"
version = "2.0.7"
edition = "2024"
rust-version = "1.91"
license = "AGPL-3.0-only"
description = "Cognitive memory engine - FSRS-6 spaced repetition, semantic embeddings, and temporal memory"
keywords = ["memory", "spaced-repetition", "fsrs", "embeddings", "knowledge-graph"]

3.3 Feature flags (8)

Flag	Default	What it turns on	Cost
embeddings	yes	mod embeddings, fastembed v5.11, ONNX inference	+~130MB model download on first run
vector-search	yes	mod search, USearch HNSW, hybrid BM25 + semantic	negligible
bundled-sqlite	yes (mutex w/ encryption)	SQLite bundled via rusqlite 0.38	+~2MB binary
encryption	no	SQLCipher encrypted DB	requires system libsqlcipher
qwen3-reranker	no	Qwen3 cross-encoder reranker	+candle-core deps
qwen3-embed	no (v2.1 scaffolding)	Qwen3 embed backend via Candle (Metal device + CPU fallback)	+candle-core, +~500MB Qwen3 model
metal	no	Metal GPU acceleration on Apple	macOS only
nomic-v2	no	Nomic Embed v2 MoE variant	+~200MB model
ort-dynamic	no	Runtime-load ORT instead of static prebuilt	required on glibc < 2.38

Default feature set ships with embeddings + vector-search. qwen3-embed is the v2.1 "Decide" scaffolding — dual-index with feature-gated DEFAULT_DIMENSIONS (1024 for Qwen3 vs 256 for Matryoshka-truncated Nomic).

3.7 Storage

• SQLite via rusqlite 0.38, WAL mode, Mutex<Connection> split between reader and writer.
• FTS5 for keyword search (bm25(10.0, 5.0, 1.0) weights).
• Migrations V1..V11. V11 (2026-04-19) drops the dead knowledge_edges and compressed_memories tables that were reserved but never used.
• Append-only audit logs: state_transitions, consolidation_history, dream_history.

3.8 Embeddings

• Default: Nomic Embed Text v1.5 via fastembed (ONNX, 768D).
• Matryoshka truncation to 256D for fast HNSW lookups (20× faster than full 768D).
• HyDE query expansion (generate a hypothetical document, embed it, search by its embedding).
• v2.1 scaffolding: Qwen3 embedding backend via Candle behind qwen3-embed feature. qwen3_format_query() helper prepends the instruction prefix ("Given a web search query, retrieve relevant passages that answer the query").
• Embedding cache: in-memory LRU; disk-warm on first run (~130MB for Nomic, ~500MB for Qwen3).

3.9 Vector search

• USearch HNSW (pinned 2.23.0; 2.24.0 regressed on MSVC per usearch#746). Int8 quantization.
• Hybrid scoring: combined = 0.3 × BM25 + 0.7 × cosine (default, user-tunable).
• DEFAULT_DIMENSIONS feature-gated: 256 on default, 1024 under qwen3-embed.

3.10 FSRS-6

• 21 trained parameters (Jarrett Ye / maimemo; trained on 700M+ Anki reviews).
• R(t) = (1 + factor × t / S)^(-w20) — power-law forgetting curve.
• 20-30% more efficient than SM-2 (Anki's original algorithm).
• Retrievability, stability, difficulty tracked per node.
• Dual-strength (Bjork & Bjork 1992): storage strength grows monotonically, retrieval strength decays.

3.11 Test count

• 364 #[test] annotations in vestige-core across 47 test-bearing files.
• Examples: cargo test --workspace → 1,292 passing (includes 366 core + 425 mcp + e2e + journey).

4.4 The 24 MCP tools

Every tool implemented in src/tools/*.rs. JSON schemas are programmatically emitted from schema() functions on each module.

1. session_context — one-call session init. Params: queries[], context{codebase, topics, file}, token_budget (100-100000), include_status, include_intentions, include_predictions. Returns markdown context + automationTriggers (needsDream, needsBackup, needsGc) + expandable overflow IDs.
2. smart_ingest — single or batch ingest with Prediction Error Gating (similarity >0.92 → UPDATE, 0.75-0.92 → UPDATE/SUPERSEDE, <0.75 → CREATE). Params: content, tags[], node_type, source, forceCreate, OR items[] (up to 20). Runs full cognitive pipeline.
3. search — 7-stage cognitive search. Params: query, limit (1-100), min_retention, min_similarity, detail_level (brief/summary/full), context_topics[], token_budget, retrieval_mode (precise/balanced/exhaustive). Strengthens retrieved memories via testing effect.
4. memory — CRUD + promote/demote. action ∈ {get, edit, delete, promote, demote, state, get_batch}. get_batch takes up to 20 IDs. Edit preserves FSRS state, regenerates embedding.
5. codebase — Remember patterns & decisions. Actions: remember_pattern, remember_decision, get_context. Feeds CrossProjectLearner.
6. intention — Prospective memory. Actions: set (with trigger types time/context/event), check, update, list. Supports include_snoozed (v2.0.7 fix).
7. dream — 5-stage consolidation cycle. Param: memory_count (default 50). Returns insights, connections found, memories replayed, duration.

4.5 MCP server internals

• src/server.rs — JSON-RPC 2.0 over stdio, optional HTTP. Handles initialize, tools/list, tools/call.
• build_instructions() — constructs the instructions string returned by initialize. Gated on VESTIGE_SYSTEM_PROMPT_MODE=full. Full mode emits an extended cognitive-protocol system prompt; default is concise.
• CognitiveEngine (src/cognitive/mod.rs) — async wrapper around Arc<Storage> + broadcast channel. Holds the WebSocket event sender.
• Tool dispatch — every tools/call invocation is routed to a execute_* function by tool name.

4.6 Dashboard HTTP backend (src/dashboard/)

• src/dashboard/mod.rs — Axum Router assembly.
• src/dashboard/handlers.rs — all REST handlers (~30 routes).
• src/dashboard/static_files.rs — embeds apps/dashboard/build/ via include_dir! at compile time.
• src/dashboard/state.rs — AppState { storage, event_tx, start_time }.
• src/dashboard/websocket.rs — /ws upgrade handler with Origin validation (localhost + 127.0.0.1 + dev :5173), 64KB frame cap, 256KB message cap, heartbeat task every 5s.

Heartbeat payload (v2.0.7): {type: "Heartbeat", data: {uptime_secs, memory_count, avg_retention, suppressed_count, timestamp}}. The uptime_secs is what powers the sidebar footer's formatUptime() display ("3d 4h" / "18m 43s").

4.7 WebSocket event bus — 19 VestigeEvent types

5. apps/dashboard — SvelteKit + Three.js Frontend

5.1 Purpose

Interactive 3D graph + CRUD + analytics dashboard. Built with SvelteKit 2 + Svelte 5 runes, embedded into the Rust binary via include_dir! and served at /dashboard/.

5.2 Tech stack

• Three.js 0.172 — WebGL, MSAA, ACESFilmic tone mapping.
• Tailwind CSS 4.2 — custom @theme block (synapse, dream, memory, recall, decay colors + 8 node-type palette).
• TypeScript 5.9 — strict mode.
• Vite 6.4 + Vitest 4.0.18 (251 tests).
• @playwright/test 1.58 — E2E ready (journeys live in tests/vestige-e2e-tests/).

5.3 Routes (SvelteKit file-based)

Grouped under (app)/:

Route	File	Purpose
/	+page.svelte	Redirect to /graph
(app)/graph	+page.svelte	Primary 3D graph (Graph3D component + color mode toggle + time slider + right panel for detail + legend overlay v2.0.8)
(app)/memories	+page.svelte	Memory browser (search, filter by type/tag/retention, suppress button v2.0.7)
(app)/intentions	+page.svelte	Prospective memory + predictions (status tabs, trigger icons, priority labels)

5.4 Root layout (src/routes/+layout.svelte)

• Desktop sidebar (8 nav items) + mobile bottom nav (5 items).
• Command palette (⌘K) — opens a search bar that navigates.
• Single-key shortcuts — G/M/T/F/E/I/S for routes.
• Status footer — connection indicator, memory count, avg retention, suppressed count (v2.0.5), uptime (v2.0.7: up {formatUptime($uptimeSeconds)}).
• ForgettingIndicator — violet badge showing suppressed count.
• Ambient orb background animations (CSS).

5.5 Components (src/lib/components/)

Component	Purpose
Graph3D.svelte	The 3D canvas. Props: nodes[], edges[], centerId, events[], isDreaming, colorMode (v2.0.8), onSelect, onGraphMutation. Owns the Three.js scene and all module init.
MemoryStateLegend.svelte (v2.0.8)	Floating overlay explaining 4 FSRS buckets — only renders when colorMode === 'state'.
PipelineVisualizer.svelte	7-stage cognitive search animation (Overfetch → Rerank → Temporal → Access → Context → Compete → Activate). Shown in /feed when SearchPerformed arrives.
RetentionCurve.svelte	SVG FSRS-6 decay curve in the graph right panel. R(t) = e^(-t/S) with predictions at Now / 1d / 7d / 30d.
TimeSlider.svelte	Temporal playback scrubber. State: enabled, playing, speed (0.5-2×), sliderValue. Callbacks onDateChange, onToggle.
ForgettingIndicator.svelte	Violet badge in sidebar showing suppressed count from Heartbeat.

5.6 Three.js graph system (src/lib/graph/)

File	Role
nodes.ts	NodeManager. Fibonacci sphere initial positions, materialize/dissolve/grow animations, shared radial-gradient glow texture (128px) that prevents square bloom artifacts (issue #31). v2.0.8: ColorMode ('type' / 'state'), getMemoryState(retention), MEMORY_STATE_COLORS, MEMORY_STATE_DESCRIPTIONS, setColorMode(mode) idempotent in-place retint. 2026-04-19: dark-glass-pill label redesign (dimmer #94a3b8 slate on rgba(10,16,28,0.82) pill with hairline stroke).
edges.ts	EdgeManager. Violet #8b5cf6 lines; opacity = 25% + 50% × weight, capped at 80%. Grow/dissolve animations.

effects.ts	EffectManager. 12 effect types (SpawnBurst, Shockwave, RainbowBurst, RippleWave, Implosion, Pulse, ConnectionFlash, etc.).
events.ts	mapEventToEffects() — maps every one of the 19 VestigeEvent variants to a visual effect. Live-spawn mechanics: new nodes spawn near semantically related existing nodes (tag + type scoring), FIFO eviction at 50 nodes.
scene.ts	Scene factory. Camera 60° FOV at (0, 30, 80). ACESFilmic tone mapping, exposure 1.25, pixel ratio clamped ≤2×. UnrealBloomPass: strength 0.55, radius 0.6, threshold 0.2 (retuned v2.0.8 for radial-gradient sprites). OrbitControls with auto-rotate 0.3°/frame.
dream-mode.ts	Smooth 2s lerp between NORMAL (bloom 0.8, rotate 0.3, fog dense) and DREAM (bloom 1.8, rotate 0.08, nebula 1.0, chromatic 0.005). Aurora lights cycle hue in dream.
temporal.ts	filterByDate(nodes, edges, cutoff), retentionAtDate(current, stability, created, target) using FSRS decay formula. Enables the TimeSlider preview.
shaders/nebula.frag.ts	Nebula background fragment shader (purple → cyan → magenta cycle with turbulence).
shaders/post-processing.ts	Chromatic aberration, vignette, subtle distortion. Parameters lerp with dream-mode.

5.7 Stores (src/lib/stores/)

Infrastructure: three-mock.ts (Scene / Mesh / Sprite / Material mocks), setup.ts (canvas context mocks including beginPath/closePath/quadraticCurveTo added tonight for the pill redesign), helpers.ts (node/edge/event factories).

5.10 Build

• pnpm run build → static SPA in apps/dashboard/build/.
• Precompressed .br + .gz per asset (adapter-static).
• Embedded into vestige-mcp binary at compile time via include_dir!("$CARGO_MANIFEST_DIR/../../apps/dashboard/build"). Every Rust build rebakes the dashboard snapshot.

6. Integrations & Packaging

6.1 IDE integration matrix (docs/integrations/*.md)

All 8 IDEs documented. The common install flow: (a) download vestige-mcp binary, (b) point IDE's MCP config at its absolute path, (c) restart IDE, (d) verify with /context or equivalent.

IDE	Config path	Notable
Claude Code	~/.claude.json or project .mcp.json	Inline in CONFIGURATION.md; one-liner install
Claude Desktop	~/Library/Application Support/Claude/claude_desktop_config.json	Inline in CONFIGURATION.md
Cursor	~/.cursor/mcp.json	Absolute paths required (Cursor doesn't resolve relatives reliably)
VS Code (Copilot)	.vscode/mcp.json OR User via command	Uses "servers" key, NOT "mcpServers" — Copilot-specific schema. Requires agent mode enabled.
Codex	~/.codex/config.toml	TOML not JSON. codex mcp add vestige -- /usr/local/bin/vestige-mcp helper.
Xcode	Project-level .mcp.json	Xcode 26.3's claudeai-mcp feature gate blocks global config. Project-level .mcp.json in project root bypasses entirely. First cognitive memory server for Xcode. Sandboxed agents do NOT inherit shell env — absolute paths mandatory.
JetBrains / Junie	.junie/mcp/mcp.json or UI config	2025.2+. Three paths: Junie autoconfig, Junie AI config, external MCP client.
Windsurf	~/.codeium/windsurf/mcp_config.json	Supports ${env:HOME} variable expansion. Cascade AI.

6.2 npm packages

Package	Version	Role
vestige-mcp-server (in packages/vestige-mcp-npm)	2.0.7	Binary wrapper — postinstall downloads the platform-appropriate release asset from GitHub. Bins: vestige-mcp, vestige.
@vestige/init (in packages/vestige-init)	2.0.7	Interactive zero-config installer. Bin: vestige-init.
packages/vestige-mcpb/	—	Legacy, abandoned.

Publish status: v2.0.6 is live on npm. v2.0.7 pending Sam's Touch ID (WebAuthn 2FA flow, not TOTP — has to be triggered from Sam's machine).

6.3 GitHub release workflow (release.yml)

Triggered on tag push (v*) OR manual workflow_dispatch. Matrix:

Target	Runner	Artifact	Status
aarch64-apple-darwin	macos-latest	vestige-mcp-aarch64-apple-darwin.tar.gz	✅
x86_64-unknown-linux-gnu	ubuntu-latest	vestige-mcp-x86_64-unknown-linux-gnu.tar.gz	✅
x86_64-pc-windows-msvc	windows-latest	vestige-mcp-x86_64-pc-windows-msvc.zip	✅
x86_64-apple-darwin (Intel Mac)	DROPPED in v2.0.7	—	❌ ort-sys 2.0.0-rc.11 (pinned by fastembed 5.13.2) has no Intel Mac prebuilt

Each artifact contains three binaries: vestige-mcp, vestige, vestige-restore.

6.4 CI workflow (ci.yml)

Triggers: push main + PR main. Runs on macos-latest + ubuntu-latest. Steps: cargo check → cargo clippy --workspace -- -D warnings → cargo test --workspace. Tonight's fix: Rust 1.95 introduced unnecessary_sort_by (12 sites fixed) + collapsible_match (1 site fixed in memory_states.rs, 1 #[allow] on websocket.rs because match guards can't move non-Copy Bytes).

6.5 Test workflow (test.yml)

5 parallel jobs: unit-tests, mcp-tests, journey-tests (depends on unit), dashboard (pnpm + vitest), coverage (LLVM + Codecov). Env: VESTIGE_TEST_MOCK_EMBEDDINGS=1 to skip ONNX model download in CI.

6.6 Xcode setup script (scripts/xcode-setup.sh)

4.9 KB interactive installer. (a) detect/install binary, (b) offer project picker under ~/Developer, (c) generate .mcp.json, (d) optionally batch-install to all detected projects. Supports SHA-256 checksum verification.

7.2 Gap analysis vs. current vestige-mcp

Dimension	vestige-mcp v2.0.7	vestige-cloud Feb skeleton	Gap
MCP tools	24	5	19 tools missing (session_context, dream, explore_connections, predict, importance_score, find_duplicates, memory_timeline, memory_changelog, memory_health, memory_graph, deep_reference, consolidate, backup, export, gc, restore, intention, codebase, suppress/unsuppress)
MCP transport	stdio + HTTP	HTTP only, no Streamable HTTP	Needs full Streamable HTTP (Mcp-Session-Id header, bidirectional, Last-Event-ID reconnect) per 2025-06-18 spec
Multi-tenancy	N/A (local)	Single tenant (one storage, one API key)	Need per-user DB, row-level scoping, or DB-per-tenant sharding
Auth	Local token	Single bearer	Need JWT, OAuth, scopes, org membership, token rotation
Billing	N/A	none	Need Stripe, entitlement, plans, webhooks
Observability	tracing only	tracing only	Need Prometheus / OTLP export, dashboards, rate limits, error budget
Sync	N/A	lossy push + unfiltered pull	Need tombstones, incremental pull by since, conflict resolution
Deploy	binaries + npm	none	Need Dockerfile, fly.toml, CI, docs

7.3 Two upgrade paths

• Path A (v2.6.0 "Remote"): Upgrade the Feb skeleton to match v2.0.7 surface (5 → 24 tools), implement Streamable HTTP, ship Dockerfile + fly.toml. Keep single-tenant. Ship as "deploy your own Vestige on a VPS."
• Path B (v3.0.0 "Cloud"): Multi-tenant SaaS. Weeks of work on billing, per-tenant DB, ops. Not viable until v2.6 has traction + cashflow.

The recommendation in Part 9 is A only for now. B is gated on demand signal + runway.

9. The Next-Phase Plan

Shipping cadence: weekly minor bumps (v2.1 → v2.2 → v2.3 ...) until v3.0 which gates on multi-tenancy + CoW storage. Ships ~Monday each week with content post same day + follow-up Wednesday + YouTube Friday.

9.1 v2.1.0 "Decide" — Qwen3 embeddings (in-flight)

Branch: feat/v2.1.0-qwen3-embed (pushed). Status: scaffolding merged; Day 3 pending. ETA: ~1 week after M3 Max arrival (FedEx hold at Walgreens, pickup 2026-04-20).

What's in: qwen3-embed feature flag gates a Candle-based Qwen3 embed backend. qwen3_format_query() helper for the query-instruction prefix. Metal device selection with CPU fallback. DEFAULT_DIMENSIONS feature-gated 256/1024. Dual-index routing scaffolded.

What's left (Day 3):

• Storage write-path records embedding_model per node.
• semantic_search_raw uses qwen3_format_query when feature active.
• Dual-index routing: old Nomic-256 nodes stay on their HNSW, new Qwen3-1024 nodes go on a new HNSW. Search merges with trust weighting.
• End-to-end test: ingest on Qwen3 → retrieve on Qwen3 at higher accuracy than Nomic.

Test gate: cargo test --workspace --features qwen3-embed --release green. Current baseline: 366 core + 425 mcp passing.

9.2 v2.2.0 "Pulse" — Subconscious Cross-Pollination ★ VIRAL LOAD-BEARING RELEASE

ETA: 1-2 weeks after v2.1 lands.

What it does: While the user is doing anything else (typing a blog post, looking at a different tab, doing nothing), Vestige's running dream() in the background. When dream completes with insights_generated > 0 or a ConnectionDiscovered event fires from spreading activation, the dashboard pulses a toast on the side: "Vestige found a connection between X and Y. Here's the synthesis." The bridging edge in the 3D graph flashes cyan and briefly thickens.

Why viral: This is the single most tweet/YouTube-friendly demo in the entire roadmap. It is the "my 3D brain is thinking for itself" moment.

Backend (≈2 days):

1. ConsolidationScheduler gains a "pulse" hook: after each cycle, if insights_generated > 0 emit a new InsightSurfaced event with {source_memory_id, target_memory_id, synthesis_text, confidence}.
2. The existing ConnectionDiscovered event gets a richer payload: include both endpoint IDs + a templated synthesis string derived from the two memories' content.
3. Rate-limit pulses: max 1 per 15 min unless user is actively using the dashboard.

Frontend (≈5 days):

1. New Svelte component InsightToast.svelte — slides in from right, shows synthesis text + "View connection" button, auto-dismisses after 10s.
2. events.ts mapping: InsightSurfaced → locate bridging edge in graph, pulse it cyan for 2s, thicken to 2× for 500ms, play a soft chime (optional, muted by default).
3. Toast queue so rapid dreams don't flood.
4. Preference: user can toggle pulse sound / toast / edge animation independently in /settings.

Already exists (nothing to build):

• dream() 5-stage cycle — YES
• DreamCompleted event with insights_generated — YES
• ConnectionDiscovered event + WebSocket broadcast — YES
• 3D edge animation system in events.ts — YES (handler exists, just doesn't emit toast)
• ConsolidationScheduler running on VESTIGE_CONSOLIDATION_INTERVAL_HOURS — YES

Never-composed alarm: Four existing components, zero lines of composition. This feature is ~90% latent in v2.0.7. All we do is press the button.

Acceptance criteria:

• Start Vestige, idle for 10 min, verify a pulse fires from scheduled dream cycle.
• Ingest 3 semantically adjacent memories from completely different domains (e.g., F1 aerodynamics, memory leak, fluid dynamics), trigger dream, verify connection pulse fires with synthesis text mentioning both source + target.
• Dashboard test coverage: add pulse.test.ts with 15+ cases covering toast queue, rate limit, event shape, edge animation.

Launch day: Film a 90-second screen recording. Post to Twitter + Hacker News + LinkedIn + YouTube same day.

9.3 v2.3.0 "Rewind" — Time Machine

ETA: 2-3 weeks after v2.2 ships.

What it does: The graph page gets a horizontal time slider. Drag back in time → nodes dim based on retroactive FSRS retention, edges that were created after the slider's timestamp dissolve visibly, suppressed memories un-dim to their pre-suppression state. A "Pin" button snapshots the current slider state into a named checkpoint the user can return to.

Backend (≈4 days):

1. New core API: Storage::memory_state_at(memory_id, timestamp) -> MemorySnapshot — reconstructs a node's FSRS state at an arbitrary past timestamp by replaying state_transitions forward OR applying FSRS decay backward from the current state.
2. New MCP tool: memory_graph_at(query, depth, max_nodes, timestamp) — the existing graph call with a time parameter.
3. New MCP tool: pin_state(name, timestamp) — persists a named snapshot (just a row in a new pins table: name, timestamp, created_at).
4. New core API: list_pins() + delete_pin(name).

Frontend (≈7 days):

1. TimeSlider.svelte already exists as a scaffold (listed in §5.5) — upgrade it to an HTML5 range input + play/pause + speed control.
2. Graph3D consumes a new asOfTimestamp prop. When set, uses temporal.ts::retentionAtDate() to re-project every node's opacity + size.
3. Edges: hide those with created_at > slider. Animate the dissolution so sliding feels organic.
4. Pin sidebar: list pinned states, click to jump, rename/delete.

Cut from scope: branching. Git-like "what if I forgot my Python biases" requires CoW storage = full schema migration = v3.0 territory. Scope it out explicitly.

Acceptance criteria:

• Slide back 30 days, verify node count drops to whatever existed 30 days ago.
• Slide back through a suppression event, verify node un-dims.
• Pin "before Mays deadline", verify pin jumps restore exact state.

9.4 v2.4.0 "Empathy" — Emotional Context Tagging ★ FIRST PRO-TIER GATE CANDIDATE

ETA: 2-3 weeks after v2.3 ships.

What it does: Vestige's MCP middleware watches tool call metadata for frustration signals — repeated retries of the same query, CAPS LOCK content, explicit correction phrases ("no that's wrong", "actually..."), rapid-fire consecutive calls. When detected, the current active memory gets an automatic ArousalSignal boost and a frustration_detected_at timestamp. Next session, when the user returns to a similar topic, the agent proactively surfaces: "Last time we worked on this, you were frustrated with the API docs. I've pre-read them."

Why Pro-tier: Invisible to demo (so doesn't hurt OSS growth), creates deep lock-in, quantifiable value ("Vestige saved you X minutes of re-frustration this month"), clear paid-hook rationale.

Backend (≈4 days):

1. New middleware layer in vestige-mcp between JSON-RPC dispatch and tool execution: FrustrationDetector. Analyzes tool args for: (a) retry pattern (same query field within 60s), (b) content ≥70% caps after lowercase comparison, (c) correction regex (no\s+that|actually|wrong|fix this|try again).
2. On detection, fire a synthesized ArousalSignal to ImportanceTracker for the most-recently-accessed memory.
3. New core API: find_frustration_hotspots(topic, limit) → returns memories with arousal_score > threshold + their frustration_detected_at timestamps.
4. session_context tool gains a new field: frustration_warnings[] — "Topic X had previous frustration; here's what we know."

Frontend (≈3 days):

1. Memory detail pane shows an orange "Frustration" badge for high-arousal memories.
2. /stats adds a "Frustration hotspots" section.

Acceptance criteria:

• Simulate 3 rapid retries of the same query, verify ArousalSignal boosts the active memory.
• Simulate caps-lock content, verify detection.
• Return to same topic next session, verify session_context surfaces warning.

9.5 v2.5.0 "Grip" — Neuro-Feedback Cluster Gestures

ETA: 2 weeks after v2.4 ships.

What it does: In the 3D graph, drag a memory sphere to "grab" it — its cluster highlights. Squeeze (pinch gesture or modifier key + drag inward) → promotes the whole cluster. Flick away (throw gesture) → triggers decay on the cluster.

Backend (≈2 days):

1. New MCP tool: promote_cluster(memory_ids[]) — applies promote to each.
2. New MCP tool: demote_cluster(memory_ids[]) — inverse.
3. Cluster detection helper: find_cluster(source_id, similarity_threshold) — leverages existing find_duplicates + spreading activation.

Frontend (≈5 days):

1. Three.js gesture system: drag detection, cluster highlight (emissive pulse on all cluster members), squeeze detection (pointer velocity inward), flick detection (pointer velocity outward past threshold).
2. Visual feedback: green ring on squeeze (promote), red dissipation on flick (demote).
3. Accessibility: keyboard alternative — select node, press P / D to promote/demote cluster.

9.6 v2.6.0 "Remote" — vestige-cloud Self-Host Upgrade

ETA: 3 weeks after v2.5 ships. First paid-tier candidate if empathy doesn't convert first.

What it does: Turns the Feb vestige-cloud skeleton into a shippable self-host product. One-liner install → Docker container or fly.io deploy → point Claude Desktop/Cursor/Codex at the remote URL → cloud-persistent memory across all your devices.

Scope:

1. Upgrade MCP handler from 5 → 24 tools (port each tool from crates/vestige-mcp/src/tools/).
2. Implement MCP Streamable HTTP transport (spec 2025-06-18): Mcp-Session-Id header, bidirectional event stream, Last-Event-ID reconnect, JSON-RPC batching.
3. Per-user SQLite at /data/$USER_ID.db (single-tenant but scoped by VESTIGE_USER_ID env — "single-tenant but deploy-multiple").
4. Dockerfile (multi-stage: Rust build + fastembed model baked in).
5. fly.toml with persistent volume mount on /data.
6. docker-compose.yml for local Postgres-if-needed (probably not — stick with SQLite for self-host).
7. scripts/cloud-deploy.sh one-liner installer.
8. Docs: docs/cloud/self-host.md step-by-step.

Explicitly OUT of scope for v2.6: Stripe, multi-tenant DB, user accounts, rate limits, billing. Those are v3.0.

9.7 v3.0.0 "Branch" — CoW memory branching + SaaS multi-tenancy

ETA: Q3 2026 at earliest. Gated on:

• v2.6 adoption signal (≥500 self-host deployments)
• Sam's runway (needs pre-revenue or funding)
• Either Mays, Orbit Wars, or another cash injection

What it does:

1. Memory branching — git-like CoW over SQLite. Branch a memory state, diverge freely, merge or discard. "What if I forgot all my Python biases and approached this memory as a Rust expert" becomes a one-button operation.
2. Multi-tenant SaaS at vestige.dev / app.vestige.dev. Per-user DB shards, JWT auth + OAuth providers, Stripe subscriptions with entitlement gates, org membership, team shared memory with role-based access.

Major subsystems required:

• Storage layer rewrite for CoW semantics (or adopt Dolt/sqlcipher with branching).
• Auth: JWT + OAuth (Google, GitHub, Apple) + bcrypt fallback.
• Billing: Stripe subscriptions + webhooks + dunning.
• Admin dashboard: support, usage analytics, churn.
• Multi-region: at minimum US-east + EU (GDPR).
• Observability: Prometheus + Grafana + Sentry + Honeycomb tracing.

Explicitly NOT a v2.x goal. Any earlier attempt burns runway.

10. Composition Map

For each v2.x feature, what existing primitives does it compose?

Feature	Existing primitive	How composed
v2.2 Pulse	dream() + ConsolidationScheduler + ConnectionDiscovered event + Three.js events.ts::mapEventToEffects	Consume the already-firing events; add toast UI + richer synthesis payload
v2.3 Rewind slider	state_transitions append log + FSRS decay formula + temporal.ts::retentionAtDate() + existing TimeSlider.svelte stub	Retroactive state reconstruction + slider upgrade
v2.3 Rewind pins	smart_ingest patterns + new pins table	Thin new table + two new tools
v2.4 Empathy	ArousalSignal (already in ImportanceSignals 4-channel model) + middleware pattern + ImportanceTracker	New middleware layer feeds existing arousal channel
v2.5 Grip	find_duplicates clustering + promote/demote + v2.0.8 Three.js node picking	Cluster-level wrapper over per-node operations
v2.6 Remote	v2.0.7 MCP tool implementations + vestige-cloud Feb skeleton + Axum	Port tools; implement Streamable HTTP; containerize
v3.0 Branch	Requires new CoW storage layer — no existing primitive composes here	Greenfield storage rewrite
v3.0 SaaS	Requires new auth + billing + multi-tenancy — no existing primitive composes	Greenfield

Key insight: v2.2-v2.6 are all ≥60% latent in existing primitives. v3.0 is the first release that requires significant greenfield work. This is why sequencing matters: ride the existing primitives to revenue, then greenfield.

11. Risks & Known Gaps

11.1 Technical

Risk	Impact	Mitigation
ort-sys 2.0.0-rc.11 prebuilt gaps (Intel Mac dropped, Windows MSVC with usearch 2.24 broken)	Fewer platforms ship	Wait for ort-sys 2.1; or migrate to Candle throughout (v2.1 Qwen3 already uses Candle)
usearch pinned to 2.23.0 (2.24 regression on MSVC)	Windows build fragility	Monitor usearch#746
fastembed model download (~130MB for Nomic, ~500MB for Qwen3) on first run blocks sandboxed Xcode	UX friction	Cache at ~/Library/Caches/com.vestige.core/fastembed — documented in Xcode guide; pre-download from terminal once
Tool count drift (23 vs 24 across docs)	User trust	Reconciled in v2.0.7 (docs: tool-count reconciliation)
Large build times (cargo release 2-3 min incremental, 6+ min clean)	Slow iteration	M3 Max arriving Apr 20 will halve this
include_dir! bakes dashboard build into binary at compile time	Have to rebuild Rust to update dashboard	Accept as design; HMR via pnpm dev for iteration

11.2 Product

Risk	Impact	Mitigation
OSS-growth-before-revenue means months of zero cash	Sam can't pay rent	Mays May 1 ($400K+), Orbit Wars June 23 ($5K × top 10), part-time Wrigley Field during Cubs season
deep_reference is the crown jewel but rarely invoked	Users don't discover it	CLAUDE.md flags it; v2.2 Pulse farms the viral moment to drive awareness
Subconscious Pulse may fire too often or too rarely	User annoyance or missed value	Rate limit: max 1 pulse per 15 min; user-adjustable in settings
Emotional tagging may over-fire (every caps lock = frustration?)	False positives	Require ≥2 signals (retry + caps, or retry + correction) before boost
v3.0 SaaS burns runway if started too early	Business-ending	Gated on v2.6 adoption + cash injection
Copycat risk (Zep, Cognee, etc.) cloning Vestige's features	Eroded differentiation	AGPL-3.0 protects network use; neuroscience depth is hard to fake; time slider + subconscious pulse are visible moats
Cross-IDE MCP standard changes (Streamable HTTP spec moved 2024-11-05 → 2025-06-18)	Breaking transport changes	v2.6 implements the newer spec; keep 2024-11-05 as backward-compat alias

11.3 Known UI gaps (docs/launch/UI_ROADMAP_v2.1_v2.2.md)

• 26% of MCP tools have zero UI surface (e.g., codebase, find_duplicates, backup, export, gc, restore — all power-user only).
• 28% of cognitive modules have no visualization (SynapticTagging, HippocampalIndex, ContextMatcher, CrossProjectLearner, etc.).
• The rainbow-bursted Rac1 cascade in the graph has no numeric "how many neighbours did it touch" display.
• intention shows but doesn't let you edit/snooze from the UI.
• deep_reference is unreachable from the dashboard (it only surfaces via MCP tool calls).

12. Viral / Launch / Content Plan

12.1 Content cadence (fixed)

Mon–Fri till June 13 graduation:

• 1-2 posts/day across Twitter + LinkedIn + Hacker News + Reddit r/LocalLLaMA + r/selfhosted
• Weekly YouTube long-form (Friday release)

12.2 Per-release launch playbook

For every v2.x release:

1. Monday: Tag + release + content drop (tweet with 30-90s demo video + HN post).
2. Tuesday: LinkedIn long-form + Reddit cross-post.
3. Wednesday: Follow-up tweet thread (deep-dive on one specific feature).
4. Thursday: Engage with feedback; close issues; publish patch if needed.
5. Friday: YouTube long-form (15-25 min walkthrough). Next week's release work continues.

12.3 Viral load-bearing moments

• v2.2 "Pulse" launch: The single biggest viral bet. Subconscious cross-pollination demo → HN front page → Twitter thread → YouTube 10-min walkthrough.
• v2.3 "Rewind" time slider: Highly tweet-friendly. Screen recording of sliding back through memory decay.
• Jarrett Ye (FSRS creator, user L-M-Sherlock) outreach: Already a stargazer. Email him Sunday night (US time) = Monday AM Beijing with the v2.2 Pulse demo. If he retweets → FSRS community (Anki, maimemo) amplifies.

12.4 Issue #36 (hooks-for-automatic-memory)

Outstanding from desaiuditd. Response plan:

1. Thank him publicly in the issue.
2. Acknowledge the feature as valid and scoped for v2.2/v2.3.
3. Open a linked sub-issue: "v2.2: Auto-memory hooks" tied to Pulse work.

12.5 Monetization gates

Two candidate first-gates:

1. v2.4 Empathy (Emotional tagging) — invisible to OSS demos, strong retention, clean paid-feature framing ("Vestige notices when you're frustrated; free tier gets 100 detection events/month, Pro gets unlimited + frustration hotspot analytics").
2. v2.6 Remote (Cloud self-host binary) — "free binary forever; paid-tier cloud-managed deploy with backups + observability + multi-device sync."

Pick after v2.2 viral signal tells us whether retention or convenience is the weaker link.

13. How AI Agents Should Consume This Doc

13.1 First-time read protocol

If this is the first time you're seeing Vestige:

1. Read Part 0 (Executive Summary) + Part 1 (What Vestige Is). That's 3 minutes.
2. Read Part 9 (The Plan). That's 10 minutes.
3. Bookmark Parts 3-6 for reference.

13.2 When Sam asks you to plan a feature

1. Check Part 9 — is it already scoped? If yes, that section IS your spec.
2. If not, work it into the existing roadmap: which version should it ship in, what primitives does it compose (Part 10), what risks apply (Part 11)?
3. Follow the /Users/entity002/.claude/rules/active-synthesis.md protocol (6 mandatory behaviors): compose, don't summarize.

13.3 When Sam asks you to implement

1. Find the exact file paths in Parts 3-5.
2. Check existing test coverage (Part 5.9 for dashboard, §3.11 for core).
3. Before claiming something exists, grep or read the source — memory alone is insufficient (per CLAUDE.md SCOUR rule).
4. Rust 1.95 toolchain — be aware of the new lints (unnecessary_sort_by, collapsible_match).

13.4 When Sam asks for strategic advice

• Apply the /Users/entity002/.claude/rules/cross-reference.md rule: check evidence from the exact setup before recommending.
• Apply the always-positive-energy rule: recommend the BEST path, not the safest.
• This doc's Part 9 is the committed roadmap. Deviate only with explicit justification.

13.5 Load-bearing files to never forget

• /Users/entity002/Developer/vestige/CLAUDE.md — project-level Claude instructions.
• /Users/entity002/.claude/rules/active-synthesis.md — 6 mandatory synthesis behaviors.
• /Users/entity002/.claude/rules/cross-reference.md — exact-setup evidence rule.
• /Users/entity002/CLAUDE.md — global Claude instructions (SCOUR + always-positive-energy).
• /Users/entity002/Developer/vestige/docs/launch/UI_ROADMAP_v2.1_v2.2.md — prior UI research compilation.
• This file — /Users/entity002/Developer/vestige/docs/VESTIGE_STATE_AND_PLAN.md.
