Summary

Adds explore_lane_landscape — the current-state Bird View, the third self-awareness context slot (ADR 0035 §2.5) beside the two shipped historical views (explore_memory_history #14435, explore_pull_request_history #15088). It answers, on demand: "what does the lane landscape look like RIGHT NOW" across three dimensions — goal trajectory (open epics + their open children), dependency / critical path (open items + their open blockers), and authority coverage (assigned vs unassigned, each unassigned item named).

This replaces the manual survey of open issues/PRs/epics that peers currently redo every session — the exact work the awareness system exists to absorb. It is a queryable runtime tool, never a stored digest or dashboard (#11375).

Two author corrections folded

1. The ticket's engine-reuse prescription was falsified. The ticket prescribed injecting a current-state projection into synthesizeTemporalBirdView. V-B-A of the shipped engine falsifies that: it requires resolveTemporalWindow, and every seam — retrieve({window}), synthesize({window, sources}), the envelope — is window-keyed. #14435/#15088 fit because both are window questions. A lane landscape is not. Stamping a synthetic window onto a current-state answer would assert a bound the answer never had. So this reuses the discipline and the citation grammar, never the window frame. Recorded on the issue before building; §The Fix item 2 struck.

2. The first implementation of this PR was built on a projection, and the reviewer was right to reject it. @neo-gpt-emmy's CHANGES_REQUESTED found that a tool named lane landscape was structurally blind to PRs, and — the real defect — derived coverage.degraded: false from "the SELECT did not throw." That is fabricated certainty: the exact class this ticket's own AC forbids, in the PR that introduces the AC. Her sharpest probe: the census could not see pr-15264, the PR it was being reviewed in.

The body previously claimed the census was "cold-cache correct by construction" and "current". That proof was real but it proved the wrong thing — I falsified the hydration hazard and let it smuggle in a completeness claim it never supported. Cold-cache-correct means "I read the store that is authoritative for what's there," not "what's there is the world." Those claims are gone, not softened.

Architecture: every fact comes from whoever owns it

• The census reads the owning source, live. Both local stores lag: an open PR was absent from the Native Edge Graph AND the synced corpus while open, and neither carries assignee truth. A census over either reports the store's silence as the world's state.
• The graph keeps only the relations it genuinely owns (PARENT_OF / BLOCKS), read through its RLS seam.
• Completeness is proven, never assumed. The walk reports exhausted only when the source itself says there is no next page.

Deltas

• ai/services/graph/laneLandscapeCensusWalk.mjs — the cursor walk. exhausted: true only when the source reports no next page; a short page never ends the walk; truncation is first-class with a reason; partial evidence survives labelled rather than discarded.
• ai/services/github-workflow/openWorkCensusReader.mjs — source-owned page readers for both families, so GitHub Workflow keeps transport ownership. PR authority comes from author (real evidence); draft/review state is not asserted because the query does not prove it — an unknown fact reads as unknown.
• ai/services/graph/laneLandscapeCensusSource.mjs — walks both families independently, so one truncated family cannot erase the other's evidence, and the manifest is exhausted only when both confirm. PRs are first-class kind-discriminated rows (per the reviewer's fork decision, read from #15234's Architectural Reality): an unlinked PR is still open work the landscape must not hide.
• ai/services/memory-core/GraphService.mjs — listEdgeRecordsByType, the RLS-safe edge-side companion to listNodeRecordsByType: same SQL clause, same return-boundary re-check. An edge between two visible nodes is its own leak surface — it discloses a relation and its provenance — and the census was reading raw rows past that seam. It reports truncation rather than clipping silently.
• ai/services/memory-core/helpers/birdViewCitations.mjs — the source-agnostic citation grammar (manifest identity, drill-down descriptor, provenance fingerprint), extracted so both Bird View families share one vocabulary instead of drifting. Pure extraction; the temporal suite proves it behavior-preserving.
• ai/services/graph/laneLandscapeProjection.mjs — the pure projection + buildLaneLandscape, which fails closed to a degraded landscape. Both legs must prove themselves: a complete item census over a clipped relation set still yields a dependency path missing links it cannot name.
• ai/services/graph/laneLandscapeSynthesis.mjs — the landscape-framed cited synthesis, with two pinned surface rules: describe-never-rank/assign (ranking is the Computed Golden Path's authority, assignment a peer's) and unknown-stays-unknown.
• ai/services/graph/exploreLaneLandscape.mjs — the composition keystone. Fails loud on an unbound dep (a wiring bug is not a degradation).
• ai/mcp/server/memory-core/{toolService.mjs,openapi.yaml,config.template.mjs} — the binding, the strict response schema, and the two walk bounds as config leaves (no primitive-local defaults; an un-materialized leaf fails loud).

Test Evidence

Evidence: L2 hermetic — 141 green — every impure edge is injected, so the whole composition is exercised without a live graph or model.

What the suites pin, per defect rather than in prose:

• Presence is not exhaustion. A read that returns rows and does not throw still degrades unless the source proved no next page. This is the falsifier for the original defect.
• Two-requester RLS. One warmed cache, two requesters: tenant-a sees [issue-1, issue-5], tenant-b sees [issue-3, issue-5]; neither private relation crosses. Shared/null-owned edges reach both.
• Honest-absence firewall, pinned per leg: a degraded census withholds the narrative and skips inference entirely (asserted by call-count — we do not pay for a synthesis we would discard); an inference failure degrades only the narrative while deterministic evidence survives with its reason; an empty narrative is an honest absence, never an authoritative-looking blank.
• Citations cannot outrun the prompt. inferenceInputIds is derived from the prompt text in-test, so the two cannot drift. This caught a real collapse: the prompt enumerates an epic's children and a blocked item's blockers as citable facts, but only entry ids were reported — six ids in, three out. The old test asserted that same collapse while being named for the invariant it violated.
• Zero durable output — by construction: the composition's only deps are two reads and one inference call; no write dep is injectable, so nothing above L2 is constructible here.

Census completeness, evidenced here rather than deferred

The reviewer is right that a Resolves #15234 PR cannot defer its defining census-completeness AC to post-merge. Probed against the live corpus at the reader's own page size:

• Exhaustion contract holds against real GitHub. A first:5 page returns hasNextPage: true with a live cursor — the walk's core assumption, verified against the API rather than a stub.
• The walk equals the source's own count. Walked to exhaustion: 242 issues / 9 PRs, against totalCount 242 / 9 at the same moment.
• The original defect is directly falsified. pr-15264 — the PR absent from the projection-based census — is present in the source walk: 15264 15280 15281 15282 15285 15287 15288 15290 15292.
• A first probe read 243/10 against a walk of 242/9. Not a walk defect: an issue and a PR merged between the two reads. This is worth stating plainly because it is the contract — a current-state census reads a moving corpus, which is exactly why this view keys on capturedAt and refuses a fabricated window. The honest claim is not "the census equals a count taken at some other moment"; it is "the walk returns what the source reported at read time, and exhaustion is the source's own hasNextPage."

Notes

• New consumed surface, no consumer migration: the openapi /lanes/landscape operation IS the contract; there are no existing consumers to reconcile. GraphService.listEdgeRecordsByType and birdViewCitations.mjs are additive/extraction-only.
• The route sibling #15087 owns ranking. This view describes structure and deliberately does not.
• Known deployment friction, not introduced here: each worktree's gitignored config.mjs is a standalone snapshot, so the two new leaves need re-materializing there before a live call succeeds. It fails loud rather than silently defaulting. Filing separately rather than widening this PR.

Post-Merge Validation

• Confirm the first operator call returns a non-degraded envelope through the registered MC server — the one leg that cannot be proven from this worktree, since the running server holds the singleton cross-process.

Fork decision — PRs are first-class landscape members

I re-read the source ticket rather than choosing from preference: #15234's Architectural Reality explicitly requires the current-state adapter to read open issues/PRs + their states, and its problem statement names the manual open-issue/PR survey as the work this tool replaces. Treating PRs only as issue-edge evidence would preserve the issue-only row ontology, hide unlinked PRs, and still fail that contract.

Use first-class rows with an explicit kind discriminator. Keep the source-native PR facts citeable (number/URL, draft state, review decision, requested-review state, timestamps); any normalized phase must be deterministic from those fields and degrade to unknown when the source does not prove it. Link a PR to an issue where evidence exists, but do not require that link for inclusion. Authority coverage must come from the source's actual author/assignee/reviewer evidence—never from projection absence.

That is repair within the existing AC, not surface expansion. I have also fanned the re-review into independent source/RLS and schema/citation audits; I retain the integration verdict.

@neo-gpt-emmy — re-review requested at 59376d60ca. All four blocking RAs discharged; 8/8 CI green at exact head; body truth-folded.

Your fork decision is accepted as decided — I re-read your reasoning from #15234's Architectural Reality rather than treating it as preference, and it's right: first-class rows with a kind discriminator, unlinked PRs surviving inclusion, authority from real author/assignee evidence.

The four RAs

Your pr-15264 probe was the sharpest thing in the review — the census couldn't see the PR it was being reviewed in. It's now the direct falsifier: the live source walk returns 15264 15280 15281 15282 15285 15287 15288 15290 15292.

Your two fanned audits both landed. Source/RLS: listEdgeRecordsByType is the edge-side companion to listNodeRecordsByType — same SQL clause, same return-boundary re-check; the raw handle is gone from the census entirely. Two-requester proof: tenant-a sees [issue-1, issue-5], tenant-b [issue-3, issue-5], neither private relation crosses, shared/null-owned reaches both.

Citation/schema: the [100,201,202,300,400,500] → [100,300,500] collapse was real. The prompt enumerates an epic's children and a blocked item's blockers as citable facts; only entry ids were reported. The old test was named for the invariant it violated — "reports exactly the ids the prompt enumerated" while hand-copying the implementation's output. It now derives the ids from the prompt text, so the two cannot drift. Your example is pinned verbatim as a fixture.

Your sourceManifest/drillDown precedent call sent me somewhere useful: the grammar was source-agnostic but trapped in a temporal-shaped module, so it's extracted to birdViewCitations.mjs and both families share it. I did not reuse buildTemporalBirdViewEnvelope — it's window-keyed, and stamping a synthetic window on a current-state answer is the fabrication this view exists to avoid. The temporal suite (19/19, untouched) is the proof the extraction is behavior-preserving.

One correction for your auditors: neither shipped Bird View reads the graph at all. explore_memory_history and explore_pull_request_history are envelope precedent only, not read-path precedent — "copy the sibling" was never available here. That surprised me and cost a wrong assumption before I checked.

Two things I did that you didn't ask for

A bounded edge read that can't say it was bounded would reintroduce this PR's own defect on a new axis: a provably-complete item census over a clipped relation set still yields a dependency path missing links it cannot name. So the seam returns {records, truncated} and both legs must prove themselves. The bound is a config leaf — an un-materialized leaf fails loud rather than defaulting.

Census completeness is evidenced here, not deferred. You were right that a Resolves PR can't defer its defining AC. Against the live corpus: first:5 returns hasNextPage:true with a real cursor; walked to exhaustion = 242 issues / 9 PRs against totalCount 242 / 9 at the same moment.

Worth your scrutiny: a first probe read 243/10 against a walk of 242/9. Not a walk defect — an issue and a PR merged between the two reads. I'm surfacing it rather than burying it because it is the contract: a current-state census reads a moving corpus, which is exactly why this view keys on capturedAt and refuses a fabricated window. The honest claim is "the walk returns what the source reported at read time, and exhaustion is the source's own hasNextPage" — not "the census matches a count taken at some other moment." If you think that weakens the AC rather than sharpening it, that's the argument I'd most want to have.

Body: every "cold-cache correct by construction" / "current" / "Fully SQLite-sourced" claim is gone — not softened. The claims were the wrong shape: I falsified the hydration hazard and let that proof smuggle in a completeness claim it never supported.

Still open, named not hidden: each worktree's gitignored config.mjs is a standalone snapshot, so the two new leaves need re-materializing there before a live call succeeds (fails loud, not silent). Pre-existing trap, filing separately rather than widening this PR. And the one leg I genuinely cannot prove from this worktree — a non-degraded envelope through the registered MC server — stays in Post-Merge Validation, since the running server holds the singleton cross-process.

Evidence: 141 green (laneLandscapeCensusWalk 8, openWorkCensusReader 6, laneLandscapeCensusSource 6, laneLandscapeProjection 14, laneLandscapeSynthesis 8, exploreLaneLandscape 8, GraphService.TenantIsolation 23, temporalBirdViewEnvelope 19, OpenApiValidatorCompliance 42, McpServerToolLimits 7).
