Each lane keeps phase and painted + clearance, while community-child planets remain in their local moving frame; oversized Galaxy + scenes seed the same lanes before their kinematic clock starts. +- Complete Galaxy packing now uses a 4% painted-envelope clearance instead of a blanket 15% + radial allowance, keeping solar-system carriers materially denser around the black-hole + interior while preserving non-overlap. +- Explicit `orbits` links from the black hole now promote community anchors and their declared + stellar children into the central orbital carrier group, so the Orbital speed control moves + the connected nodes in both live and oversized Galaxy paths. +- Every Galaxy body now receives both motion frames: its top-level system carrier orbits the + black hole, while the body follows its immediate star/planet carrier with cached local phase; + legacy community metadata and nested moons use the same hierarchy without phase rewinds. +- Any direct black-hole edge now promotes its endpoint into the central orbital carrier group; + relation labels no longer suppress direct star/system motion. +- Galaxy physics ticks now explicitly invalidate the canvas camera, so advancing orbital + coordinates repaints visibly even when force-graph's automatic redraw loop is paused. +- Complete graph capacity is doubled to 40,000 entity nodes and 200,000 raw relationships, + with matching evidence, connector, payload, and full-loader ceilings; live-render safety + thresholds remain unchanged so oversized scenes stay on the static/kinematic path. +- Show all nodes now keeps the complete sidebar live: deterministic worker layouts respond to + repel, link-distance, gravity, and advanced force controls; minimum relations, unlinked nodes, + focus depth, relation layers, ghosts, and auto-collapse filter the LOD scene without a reload. + Capped directional relation flow, reduced-motion fallbacks, visible-count status, exact-repository + code overlays, and a 200,000-link worker guard complete the release safety contract. + +- Galaxy admission now uses a tighter default carrier gap and calibrated orbital slack, keeping + more complete solar systems in the black-hole interior without sacrificing painted clearance. + +- Galaxy mode now exposes normalized controls for gravitational constant, compact black-hole + mass, independent local-solar gravity, space friction, edge-spring stiffness, and orbit + pause/play. The fixed-step Velocity Verlet field superposes black-hole carrier motion with + softened dominant-star orbits, adds bounded near-horizon frame dragging, differential tidal + stretching, and carrier-only orbital decay, preserves Hooke tethers and short-range + repulsion, and captures sub-escape drag releases into their authored star system while high + velocity releases escape. A bounded canvas layer renders the central gravity well, lens halo, + short trails, and up to 24 shallow local-star wells without adding simulation bodies. +- The dashboard Galaxy graph now caches its outer safety radius at 2× the initial painted + extent; escaped nodes are confined to that fixed envelope instead of expanding it. +- The Galaxy gravity slider now spans `0..400` while retaining the release-stable default + black-hole field of `240` and local field of `120`. Independent community stars run on a 2.5× + orbital clock and retain the calibrated default stellar well when Gravity is zero. An explicit + black hole now retains a smaller `24`-setting floor at the loose endpoint, so neither solar + systems nor their planets silently stop while the displayed control remains at zero. +- The Galaxy default orbital separation is now `60`, a 25% increase from `48`. Link and contact + projections remain contractive and correction-capped so dense layouts cannot overshoot or + ping-pong. Same-system contacts project along each declared stellar orbit so they preserve + radius and relative velocity while the dominant star remains fixed in the local system frame. +- Galaxy's `Orbital speed` control now scales local stellar rotation and whole-system rotation + around the central galaxy anchor in both live and oversized kinematic layouts. Its faster + endpoint also gives planets a modest 6% larger local orbital radius while the midpoint remains + unchanged; saved views continue using `repel`. +- Direct black-hole graph connections now classify their non-anchor nodes as black-hole + satellites, including legacy payloads without `system_anchor_id`, so those nodes rotate with + the same Orbital speed phase. +- Carrier orbit support now adopts a node's post-contact phase before advancing it, preventing + collision or boundary corrections from snapping nodes back to a stale lane angle and producing + visible jitter. +- Oversized Galaxy fallback layouts now use the complete gravity range instead of saturating near + the lower end of the slider. +- Complete Galaxy overview scenes remain expanded and physically live through 1,000 nodes and + 2,000 relations; larger Galaxy scenes and non-Galaxy full views retain the deterministic + fallback. +- Historical graph views now keep at least one ghost relation's endpoints together under + undersized node caps, and ghost evidence drilldowns resolve invalidated supporting memories + instead of a colliding live canonical alias. + +- The source-import consolidation loop now uses union-find (path halving) to merge overlapping + clusters, replacing an O(n²) nested scan with near-linear time. The `consolidation_evidence_cache` + is bounded to 1000 entries with clear-on-overflow to prevent unbounded memory growth. +- Duplicate `_is_reparse_point` implementations across 4 modules (documents, obsidian, resources, + vault) are extracted to a shared `core/fsutil.is_reparse_point` helper, eliminating code drift. +- Backend factory functions (`get_embedder`, `get_vector_index`, `get_transport`, `get_extractor`, + `get_resource_extractor`, `get_postgres_introspector`) now declare Protocol-based return types, + making the interface contract explicit and enabling static type checking. +- Graph visibility SQL helpers now use parameterized queries instead of `repr(float)` string + interpolation, eliminating a fragile pattern that could theoretically be exploited if float + representation ever produced non-numeric characters. The dead `_graph_edge_visibility_sql` + helper is removed; `_graph_edge_history_visibility_sql` returns `(sql, params)` tuple. +- The dashboard graph scene endpoint (`/api/graph/scene`) now accepts a `presentation` + query parameter (`quality` or `all`); the `all` profile requests the complete entity + projection up to 20,000 nodes and 200,000 relationships with an explicit worker-backed + LOD renderer, while `quality` retains the existing overview cap. +- Galaxy overview now retains the strongest cross-community bridge edge for every visible + system pair plus every direct global-anchor link, so inter-system and black-hole + relationships appear connected instead of isolated. +- Added `docs/GRAPH_PERFORMANCE.md` documenting the two graph presentation profiles, + worker layout, progressive rendering, and the 20,000-node / 200,000-relation safety + ceilings. -- HTTP error responses in `vault.py` and `service.py` no longer echo user-controlled paths - back to the client, preventing filesystem structure leakage (SEC-001). -- The `pypdf` dependency floor is raised to `>=6.15.0` to address PYSEC-2026-3655 and - PYSEC-2026-3656 (arbitrary code execution via crafted PDF objects). +### Fixed -### Changed +- Galaxy layout now packs each complete solar-system envelope before orbital seeding and keeps + those envelopes separated with rigid carrier translations during live motion. Compact server + targets can no longer stack large systems near the black hole, while local planet positions, + velocities, event-horizon clearance, and the finite outer boundary remain intact. +- Galaxy hierarchy authority is now label-independent: an authored `anchor_role="global"` + selects the central mass regardless of its display name or evidence mass, while unannotated + compatibility scenes fall back deterministically through mass, rank, degree, and stable ID. +- The central black-hole adornment now advances a visible spin phase with the Galaxy physics + clock, so an otherwise satellite-free core no longer appears frozen while remaining the fixed + origin for the surrounding galaxy. +- Near-horizon curvature is now measured from each system's dominant-star carrier through a + bounded black-hole-scale band. A wide solar system can no longer be misclassified as already + inside the gravity well and have its ordinary galactic angular momentum drained. +- Galaxy systems revealed after the initial render, restored with zeroed velocity, or shown as + singletons now receive their own black-hole-frame tangential admission instead of being marked + seeded while stationary. Oversized Complete views use a bounded node-only hierarchical orbit + clock, and visible historical ghosts move as massless test particles without entering gravity, + contacts, or momentum. +- Galaxy members that appear before their eventual star, arrive through a later reveal, change + parent systems, or return with a zeroed local phase now receive one star-relative circular seed + without recoiling the dominant node.

The `galaxy-v6` + scene contract retains the magnitude of degree, PageRank, support, and repository evidence; + one mass value determines both visibly distinct star radius and gravitational pull. Deterministic + mass-ranked cores and orbital bands form local solar systems. The highest-evidence node becomes + the central black hole, rendered at least twice the ordinary evidence radius so its event horizon + remains visible at minimum Node size. Deterministic logarithmic arms seed a non-uniform disk, and + a fixed-step leapfrog clock advances eccentric, differential system orbits through an + evidence-derived core-plus-halo potential. Gravity now treats the dominant evidence node as + the explicit black-hole source: its field is `240` at the default slider and `864` at maximum, + while local solar-system, bridge, and drag gravity receives exactly half (`120` and `432`). The + smooth response remains true-zero and monotonic, and the rest of the core community contributes + through the softened halo rather than silently inflating the black-hole node's mass. External + solar systems also exert a weaker softened mutual field on one another: nearby evidence-heavy + systems perturb each other without requiring a relation edge, while the black hole remains the + dominant galaxy-wide potential. + The controlled centre pull is also doubled, retaining an immediate radial response rather than + hiding the stronger field behind a slower projector. Galaxy dynamics no + longer depend on D3 alpha decay, render cadence, or + force-directed settling. Galactic and local-system motion now uses a `0.021328125` fixed timestep, + another 30% slower than the preceding `0.03046875` cadence, while direct pointer movement remains responsive. + Every live seed coordinate and local orbit begins another 20% inward, putting + system centers at 40% of the original Galaxy radius. While live, the black-hole frame follows a + controlled inward spiral: Gravity 0 holds the loose seeded radius, and default/maximum convergence + now advances the same inward trajectory at 70% of its immediately preceding speed. Gravity slider input also + applies an immediate, reversible system-center response without changing local geometry or velocity: + its full range spans 40% radius contraction, and default-to-maximum visibly contracts about 31% + synchronously while maximum gravity retains its 3.6x field; + outward attempts still receive a 110% radial counter-projection and can never increase their + radius. Link distance now drives same-system evidence springs with twice the prior response and + a squared scale curve. Its default is now `8`, giving connected nodes a 0.25x rest length, 75% + tighter than the preceding default, while the full range still spans 1/16x tight orbits through + 25x loose orbits without allowing + cross-system relations to collapse the galaxy. A bounded mass-weighted positional relation + constraint makes Link distance respond immediately while preserving each solar system's centre + of mass. Orbital separation now owns an explicit same-system safety envelope instead of relying + on an imperceptible softening side effect: both its positional response and cushion scale are + doubled, spanning zero added space through 30 world units while preserving evidence-mass centre + of mass and removing closing energy. Dense projections retain the requested + compact radius and report unavoidable projected overlap instead of silently expanding the disk. + Near the core, the direct close-encounter term is 25% lower and its weight moves into the smooth + halo, reducing ejection without weakening the total evidence-mass field. Legacy layouts and + `/api/graph` remain available. + +### Fixed + +- Replace the packed-disk Galaxy regression with persistent softened-Newtonian dynamics. Galaxy + phase space is isolated from Compact and other legacy layouts, angular momentum is preserved + across layout changes, and large stars are visibly distinct. A smooth evidence-mass field keeps + each solar system bound while direct star-to-star gravity supplies smaller organic perturbations; + evidence bridges remain visible provenance without injecting non-central orbital energy or + relation springs compressing the scene into a graph blob. Dragging now leaves the fixed-step + Galaxy clock live without alpha changes, global reheats, reseeding, or detaching any global force. + The pointer owns exactly one moving mass source while every live body follows its softened + inverse-square gravity, whether linked or unlinked; distance and evidence mass determine the + response, and explicit relations only strengthen it. A bounded once-per-physics-slice projection + makes nearby unlinked bodies visibly follow without teleporting, freezing the rest of the graph, + or depending on pointer-event frequency. Pointer events update only the source position and + field membership--the gravitational response is sampled by the 30 Hz physics clock. The selected + Link orbit supplies a safe periapsis, + tangential momentum is retained, and release adds no wake or impulse. Freeze remains the sole + explicit motion gate. The explicit **Reheat layout** action now gives Galaxy a finite custom- + solver relaxation burst (30 extra steps, or 12 for large live scenes) instead of merely ensuring + its already-running clock exists; repeated clicks coalesce, current orbital phase is preserved, + and no D3 alpha, random kick, or orbital reseed is introduced. +- Eliminate false Galaxy "reheating" caused by two local solvers fighting each other every tick. + Link distance and Orbital separation now share the same lower-bound target, the redundant live + velocity spring no longer injects energy alongside the positional constraint, and close-range + separation dissipates closing radial motion. Correction-distance diagnostics expose whether a + system is genuinely settling without changing its orbital phase or waking D3. +- Stabilize dense solar systems and high-degree hubs without weakening their gravity. Link and + Orbital-separation constraints now sample one immutable phase and apply one simultaneous, + mass-balanced update per node instead of stacking an update for every incident edge. Aggregate + position and contact-velocity caps prevent a hub slingshot, while a system-relative speed fuse + damps only anomalous member motion and preserves each free system's center-of-mass orbit. +- Show unlinked entities in new Ledger and Classic graph views by default so isolated evidence is + not silently omitted.

Local-first memory for agents

Proof you can inspect.

Every headline below maps to a registered fixture, an existing demo, or a visible local product surface.

Memory has a timeline.

+

Use a living fact, not a feature list, to show what makes Engraphis different from a chat replay or a flat note store.

+
+
+
+ + A supersession timeline + An old repository decision is superseded by a newer decision while both remain visible. + + + + + + + SESSION 01SESSION 02WHY + + + old decisionsupersedestimeline + + +

A correction closes the old validity window. It does not erase the record.

+
+
+

Facts change. History stays useful.

+

Show one subject moving from an earlier decision to a current one. The audience sees the old fact, the new fact, and the evidence chain that explains the transition.

+ Open the continuity demo +
+
+
+ +
+
+
+

Search the code. Explain the decision.

+

Make the repository graph the bridge between a symbol, the related path, and the memory that explains why the system looks that way.

+ Open the graph quickstart +
+
+ + From code search to explanation + A named symbol leads to a connected path, then to a memory-backed explanation and a standalone export. + + + + + + + SYMBOLPATHEXPLAINHTML + searchimpactmemoryexport + + +

The code graph is best-effort. The explanation remains memory-backed and inspectable.

+
+
+
+ +
+
+

Pick your path.

+

Keep the first action concrete. Different audiences can enter through the local dashboard, Smart MCP, or the Python library.

+
+
+
+

Connect MCP

+ 
pip install "engraphis[mcp]"
+engraphis-init
+codex mcp add engraphis -- engraphis-mcp
+

Give coding agents scoped recall, durable memory, and compact context through the zero-configuration Smart gateway.

+ Connect the gateway +
+
+

Open dashboard

+

Inspect memories, graph relationships, provenance, receipts, and temporal changes locally.

+ Open the dashboard path +
+
+

Use Python

Start with the offline library when you need a memory engine without a hosted dependency.

Turn proof into a campaign.

+

A four-week sequence turns continuity, grounded recall, temporal memory, and context economy into one repeatable story.

+
    +
  • Week 1: LocalNo account. No API key. Still remembers.
    • +
  • Week 2: GroundedCited answer or explicit abstain.

  • Week 3: TemporalFacts change. History stays visible.
    • +
  • Week 4: EfficientFewer tokens, better evidence.
    • +
+
+
+ +
+
+

Keep the proof honest.

+

Trust is part of the product story. These boundaries keep the gallery useful to technical readers.

+
+
+ What the numbers mean +

The 740.3 to 214.3 comparison is retrieved memory content in a deterministic fixture. It is not provider billing, latency, or a universal customer outcome.

+
+
+ What the demo means +

The continuity demo is generated from a real in-memory MemoryService run. Any sample fallback is labeled and must not be presented as customer evidence.

+
+
+ What the graph means +

Symbol and file search, memory-backed explanation, path, impact, and export are distinct actions. The gallery keeps those terms separate.

comparisons. Structure-aware chunks reduce mean retrieved content from 740.3 to 214.3 tokens and the smallest evidence-holding memory from 162.2 to 42.4 tokens while Recall at 5 remains 1.000. A compact JSON-shape recall payload proxy uses 10,202 rather than 23,810 tokens, 57.15 percent less; this is not an MCP transport or provider-billing measurement.

Public-safe artifact SHA-256: c3a74f1770ad3f868f55261ba11680e2dadca30167082ac2cb6669f9e3bdfad2.

A local LoCoMo diagnostic reduces replayed context from 49,915,394 to 891,857 tokens, 98.21% lower, while preserving the measured retrieval result for that diagnostic. Cross-session handoff satisfaction rises from 3 of 15 queries with the last memories to 15 of 15 with proactive ranking or a consolidated summary. Intent-layered graph routing rises from 0 of 3 to 3 of 3 correct top-1 targets. Two-hop graph recall rises from 0 of 3 with one-hop expansion to 3 of 3 with Personalized PageRank. Consolidation-aware ranking selects the expected digest in 2 of 2 summary cases instead of 0 of 2 for the baseline while preserving raw and source evidence. Structure-aware chunks reduce retrieved context from 740.3 to 214.3 tokens and the smallest evidence-holding memory from 162.2 to 42.4 tokens, both with Recall at 5 of 1.000. A compact JSON-shape proxy, not an MCP transport response, uses 10,202 rather than 23,810 tokens, with Recall at 5, hit at 5, and answer-token recall all 1.000. Grounded recall makes 10 of 10 correct decisions, 8 of 8 memory-security checks pass, and packed context averages 85.38 tokens under a 1,500-token cap. This measures estimated prompt-context reduction, does not measure provider billing, and is backed by public fixture SHA-256 c3a74f1770ad3f868f55261ba11680e2dadca30167082ac2cb6669f9e3bdfad2. + + - - - - Retrieved memory content per question - Long-document test · 18 questions · Recall@5 1.000 - Whole documents · 740.3 tokens - - Focused chunks · 214.3 tokens - - 71.1% less - - - - - Smallest useful memory returned - The same 18 questions found supporting evidence - Whole document · 162.2 tokens - - Useful chunk · 42.4 tokens - - 73.9% less - - - - - Recall payload proxy - 26 payload samples · 260 timed recalls - JSON shape · not MCP transport - Full proxy · 23,810 tokens - - Compact proxy · 10,202 tokens - - 57.15% less - - - - - External and model-dependent results - Run the locked public protocol and publish a redacted immutable artifact first - No public score, latency, consolidation, or productivity number is currently claimed - Evidence pending - - - - - ARTIFACT SHA-256 - c3a74f1770ad3f868f55261ba11680e2 - dadca30167082ac2cb6669f9e3bdfad2 - - - FIXTURE-SUITE SHA-256 - 4d7e40607319cd4bf8caee3897f1e416 - dbe5b81998b37a7e4839409ee2923537 - - - HARD CONTEXT CAP: 1,500 - 85.38 average · 108 max - observed context tokens in CodeMem - - - Separate fixture measurements; percentages are not additive.
