Organize graphs around their topology with readable card and wire clearances #233

Dense graphs must remain readable at useful zoom, with original-item access, generous card/wire margins and recoverable navigation. The owner identified EPIC2215 with107 essential neighbors butzero visible endpoints; this is now the principal acceptance case. Continues #193 and the detailed wiring work in #220.

Done

• Deterministic connectivity-aware Organize, central hubs/chains/components, measured heterogeneous card spacing and bounded refinement; preserves complete canonical membership and existing save/receipt lifecycle.
• Overview buses:64px card gutters,20px unrelated-card clearance,16px wire separation, exact directed original accounting, coverage and accessible hover/keyboard inspection. Actual301desktop/phone and72nested journeys accepted for the earlier foundation.
• Composed accepted dev479edf6/PR236. Actual post-dev overview performance/input issues Keep overview zoom within the five-second budget on 2,000-item graphs #235 and Make overview buses inspectable with endpoint highlighting #231 are closed after independent117-case/2k acceptance. Their earlier5.119s failure remains recorded.
• Local Items projection: original focus + real neighbors + live semantic summaries, at most7cards; paging/group filters, exact original-edge selections, original inspector/editor, pan/Back/reload state. Display positions never enter saved layout. Phone retains one original neighbor when two cards fit.
• Phone footer spans the screen, app tabs use equal columns and44/48px controls.152px three-line18px cards fit the actual shorter390×811 canvas with64px card gap/20px footer margin.
• [x]4ee5120 fixes reviewed navigation/filter blockers.17targeted navigation/inspector/layout controls and web types pass. Real107-neighbor desktop/phone acceptance passes2/2 in45.6s: painted geometry, invisible-wire negative, hover/keyboard original IDs, paging/filter, focus/Back, pan/reload, one exact original-title edit, unchanged allpositions/metadata/edges andzero unexpected writes/errors.

Next

• [x]181dfa0 consumes navigation intent once, uses monotonic sequences and binds/resets owner+graph scope. Remount/repeated same-ID controls pass; independent source review confirms fixed.
• [x]58a47c5 separates typed controls/footer/card presentation.23c3d1f reserves the full three-line title envelope; the real60px narrow-page clearance negative is corrected. Final44model/layout/controller/inspector controls pass.
• [x]Added hosted2k/5k dense focus phase (107added neighbors,111totaldistinct), local→overview→local, unchanged5s zoom budget; original ordinary-detail/priority/input/no-write gates remain. Actual in-memory x/y/fx/fy comparisons added.
• Accept final hosted execution and inspect all strict/runtime/package artifacts; no heavy local matrix.
• Freeze/push, independent exact-source and artifact review, all relevant branch CI/runtime/package checks, native exact-head dev-only merge, actual post-dev acceptance, then close233.

Running/resume: frozen 41c1fa015e16ae9e8cfe54c3336ff68100df29b6, branch feat/topology-organization-20261028, draft PR #234; live dev479edf6. CI 40826842888 and Comprehensive 40826842856 are running. Final exact-source independent review is clear; every existing review thread answered/resolved. Final-head affected3case headed run passes51.6s with actual native hit/arrow exposure negatives, canonical D3/API conservation and useful offscreen screenshot; coherent all6case run passed90.16s before test-only strengthening. One worker/zero retries, all failures retained. Current actual2k archive/runtime acceptance and dev integration/post-dev gates remain pending.

Earlier23c/762CI failed the stale compact “Sync paused” expectation;41now requires exact “Paused”, full unchanged accessible label and expanded sync description. Independent evidence review also corrected nonexistent native selectors, a premature tiny-card screenshot and a readiness predicate that rejected valid vertical SVG wires. Negative/control receipts and causes live in the canonical lesson. No blind retry or threshold relaxation.

Read docs/architecture/local-item-lod.md, .agents/inbox/2026-10-29-high-degree-detail-needs-local-lod.md, plus topology architecture/lesson. Preserve original localhost graph; owned copies/fixtures only. The headed owned301/370EPIC copy remains available for human review. CodeGraph techniques only, no shared library. General arbitrary detailed routing #220, main/release/deploy and hosted parity remain separate.
