Result

GitLineage now uses one Repository Explorer for coexisting Origins, Dependencies, References, structure and discovery observations, with an independent Git History log that returns to the preserved graph. Local expansion, collapse, focus, search and restored exploration state retain object identity. Inspector evidence, source comparison and exports remain available without promoting similarity to ancestry.

This closure fixes the following regressions:

• Private Beta acceptance waited for removed .plate-row elements. It now expands a real group, selects a member by keyboard, opens its relationship evidence and explicitly opens the export disclosure. Login, authorization, framing protection, selection/camera continuity, download redaction and logout checks remain intact.

• A shared node could obstruct the router's preferred exit. Routing now retries real boundary ports and checks endpoint interiors as well as unrelated obstacles. Canonical and composed renderers no longer silently omit failed routes or substitute unsafe curves: paired inspectable endpoint badges expose an obstructed connection without inventing a line or changing its identity, direction or evidence.

• Responsive focus acceptance now waits for replacement of the old SVG node before asserting focus on its replacement. CSS width alone could satisfy the old wait before the resize redraw. The focus requirement is unchanged.

docs/project-state.md now describes implemented workspace/History behavior, current anonymous request accounting and bounded continuation. Earlier live/deployment results are explicitly historical.

Validation

Local typecheck, production build, Unit (613 pass, 3 existing live skips) and Discovery (136 pass) passed. Chromium fixture acceptance covers Canvas, Landing, Analysis, Preflight, stale A→B, UI Contract, Responsive, Mobile, Deep Search, unified workspace/History and anonymous exploration, normal Private Beta and trusted loopback TLS/Caddy staging. Spatial regressions sample actual SVG paths and check collision clearance, visible parent connectivity, unique shared objects, collapse/restore and actionable routing fallback. Key flows run at 390, 430, 1280 and 1920 px. Production-disabled guards and unchanged production bundle hashes are checked.

Both native ARM64 merge-review gates passed on final development HEAD cb79ba97776e652d764528249c506d321bc4cecc:

• M2 PR validation — success, including normal Private Beta, trusted TLS/Caddy staging and unchanged bundle hashes.
• P0/P0.5 stable UI validation — success, including Responsive and Mobile.

Workflow results refer to the same final HEAD; earlier successful SHAs are not used as acceptance evidence.

Boundaries

Canonical Graph Schema 2.0.0, Presentation View and Discovery Sidecar remain separate. Discovery keeps verification: pending, lineageClaim: none; similarity is not Fork/Derived proof. Anonymous exploration and authenticated Private Beta retain separate ownership and budgets. Production opt-in defaults and cache isolation are preserved.

Evidence uses offline repository fixtures and fixed Mock GitHub Transport. TLS staging uses a real temporary CA, isolated browser trust and loopback Caddy; it changes no system trust or production configuration. Fresh GitHub API, WebKit/Safari and physical-device acceptance are not claimed. CPU hard isolation, absolute wire-byte caps, exhaustive repository coverage and durable server exploration sessions remain outside established acceptance.

Keep this PR Draft. No merge, main push, rebase, force push or deployment. Existing untracked tools/ remains untouched and excluded.
