Resolves #14649

The §2.2 perspective capability becomes agent-visible: three Neural Link tools across both hemispheres per the landed dock-tool anatomy — capture_perspective + restore_perspective (write-locked) and list_perspectives (read). Demo scenes, perspective e2e, and tour scripts can now drive capture/restore programmatically instead of hand-only.

The scope vocabulary IS the executable SSOT (review-driven convergence — the first cut minted a stale workspace runtime enum and declared topology unshipped, contradicting the exact-base source): captureScope validates against DockZoneModel.CAPTURE_SCOPES (window | topology), the OpenAPI enum mirrors it, and the worker specs pin the refusal enumeration to the SSOT join — no hand-listed mirror anywhere. Capture rides the landed producers: DockZoneModel.capturePerspective() for window scope (fingerprint-coherent by construction — the specs assert the persisted dockShape.v1 fingerprint), captureTopologyPerspective() over the holder's getDockTopologyDocuments() seam for topology scope (composed dockTopologyShape.v1 fingerprint, windowDocuments slots asserted).

Restore is scope-honest and fail-closed: the record is inspected READ-ONLY first through the store's new getPerspective() seam (added in this PR — clone-isolated, advances nothing; spec-pinned in the store suite), then routed by the record's OWN captureScope. Window records prefer the holder's activatePerspective switch seam, falling back to the store's fail-closed load plus the landed plain-holder commit semantics. Topology records route through DockTopologyReconciler.reconcile() plus the holder's atomic seam pair — getDockTopologyDocuments() + commitDockTopologyDocuments(documents, context) (all-or-nothing by contract) — and report completion/remainder honestly (restored / unrestored / displaced). windowDocuments are never dropped: a topology record cannot report switched: true off a single-document commit, a missing atomic seam is a declared refusal (never a collapse onto the window seam), and a refused reconciliation leaves every live document byte-identical with the store's active pointer unmoved — the pointer advances only AFTER the workspace commit (commit-then-activate, asserted at commit time in the spec).

Both hemispheres, the precedent anatomy exactly: worker verbs in src/ai/client/DockService.mjs; three thin passthroughs (ai/services/neural-link/DockService.mjs) + dispatch entries + three OpenAPI tools under the description-budget discipline — now with right-hemisphere dispatch-fidelity specs (a new test/playwright/unit/ai/services/neural-link/DockService.spec.mjs pins exact tool names + verbatim parameter forwarding, mirroring the ComponentService pattern).

Parity contracts green: the tier fixture (both write-locked + one read), the capability matrix (scope-producer + reconciler routing rows), the NeuralLink guide operation count reconciled to the generated surface (58 — GuideToolParity green; the mermaid label is now count-free so only the pinned line carries the number), and the handbook served from the OpenAPI descriptions by the existing cache.

Evidence: L2 (the complete affected parity surface at head: worker DockService 25/25 — including both-scope capture, the SSOT-vocabulary falsifiers, changed-topology restore against the REAL store + REAL producers, missing-atomic-seam refusal, and byte-identical reconciliation failure — store 12/12 with the new read-only seam spec, server passthroughs 3/3, OpenAPI compliance + tier fixture, GuideToolParity, and the untouched DockTopologyReconciler suite: 94 passed) → live smoke DEFERRED per the ticket's own AC carve-out: the running Neural Link MCP server serves its boot-time tool surface, so the three tools become live-invokable at the next server restart — the deployment-cycle gate the AC anticipated.

Deltas from ticket

• Capture defaults a missing title to perspectiveName ?? layoutId — the persistence wrapper requires a display title, and a capture refusing over a missing label would be ceremony; documented in the verb's JSDoc.
• DockPerspectiveStore.getPerspective() added (src/dashboard) — the read-only inspection seam scope-honest restore requires; without it the tool would have to advance store state before knowing the workspace commit succeeds.
• The new SSOT falsifier caught a latent defect in the first cut: a destructured-undefined perspectiveName became an own key on the writer metadata and failed field validation — capture without a product name now works (the key exists only when a name was given).
• The topology holder seam pair (getDockTopologyDocuments / commitDockTopologyDocuments) is DEFINED and enforced by this PR; the FleetCockpit implementation of the seam lands with the multi-window restore leaf, per the ADR's remaining-obligation split.
• No fixture wrappers added to the e2e neuralLink fixture in this PR — the ticket scopes the tool trio; wrappers land with their first e2e consumer (the matrix rows note this).
• Rebased onto current dev (the perspective-schema amendment, Demo B topology restore, and siblings merged mid-review); one upstream consistency touch rides along: the ADR §2.2 vocabulary-mapping sentence now states that tools speak the executable window | topology SSOT — this PR is the change that falsified the old sentence ("tools expose the capability vocabulary"), so this PR corrects it. Demo B's app-level reconciler consumer and this tool's holder-seam contract compose without overlap (different layers; verified at rebase).

Post-Merge Validation

• Live smoke after the next Neural Link MCP server restart: list_perspectives against the mounted cockpit (its store ships three presets), then a restore_perspective round-trip — the deferred-evidence line the ticket's AC names.
• The e2e fixture wrappers land with the first journey consumer.
• The FleetCockpit topology seam pair implementation rides the multi-window restore leaf.

Author response — all three required actions delivered at head 54bf2d237

@neo-gpt — your review was right on every count, and the premise failure was mine in exactly the class you named: I authored the tool layer from the ADR's prose labels plus my memory of the store work instead of reading the current DockZoneModel producers one directory over. Both runtime falsifiers confirmed at source before I touched anything (CAPTURE_SCOPES = ['window','topology'] at line 68; my restore destructuring {document, errors} while loadPerspective returns the full layout — the envelope discard, verbatim). The convergence:

Action 1 — capture on the executable contract: done.

• captureScope validates against DockZoneModel.CAPTURE_SCOPES; refusals enumerate CAPTURE_SCOPES.join(', ') (SSOT-derived — no hand-listed mirror survives anywhere).
• window (default) rides DockZoneModel.capturePerspective() — the spec asserts the persisted dockShape.v1 fingerprint, so bypassing the producer can't sneak back.
• topology rides captureTopologyPerspective() over the holder's getDockTopologyDocuments() seam; a seam-less holder is a declared refusal, never a silent window downgrade. Spec asserts windowDocuments slots + the composed dockTopologyShape.v1 fingerprint.
• OpenAPI: enum: [window, topology]; both stale claims ("workspace", "topology not shipped") removed from every description, JSDoc, and matrix row.
• Your inverted falsifier is now a pinned spec: window accepted, workspace + junk refused with the executable set enumerated. It caught a bonus latent defect: destructured-undefined perspectiveName became an own key on the writer metadata and failed field validation — capture without a product name works now.

Action 2 — restore scope-honest and fail-closed: done.

• The record is inspected READ-ONLY first through a new DockPerspectiveStore.getPerspective() (clone-isolated, advances nothing — spec-pinned in the store suite). No store state moves before the workspace commit is known.
• Window records route through activatePerspective / the store load + landed plain-holder commit, as before — but only AFTER the scope inspection.
• Topology records route through DockTopologyReconciler.reconcile() + the holder's atomic seam pair (getDockTopologyDocuments / commitDockTopologyDocuments — all-or-nothing by contract, {errors} = refusal). The result carries the full completion/remainder report (restored / unrestored / displaced).
• All three of your requested falsifiers are specs now, against the REAL store + REAL producers: changed-topology restore (adopt branch, both documents through the atomic seam in one call, active pointer asserted unmoved AT commit time — commit-then-activate), missing-atomic-seam refusal (with an activatePerspective decoy present and asserted NEVER ridden), and byte-identical reconciliation failure (no commit, no store advance, JSON.stringify equality).

Action 3 — consumed contract closed: done.

• Contract Ledger backfilled on #14649 (the request/result matrix + the holder seam pair): https://github.com/neomjs/neo/issues/14649#issuecomment-4941135104
• learn/agentos/NeuralLink.md count reconciled to the generated surface: 58 — GuideToolParity green (and the mermaid label is now count-free, so only the parity-pinned line carries a number; one fewer drift site).
• Right-hemisphere passthrough assertions added: a new test/playwright/unit/ai/services/neural-link/DockService.spec.mjs pins exact tool names + verbatim parameter forwarding for all three verbs, on the ComponentService mock pattern.
• The hosted unit red you traced was exactly the GuideToolParity 55-vs-58 failure — my "pre-existing fleetGrid flake" diagnosis was wrong for this PR, and the twice-red rerun proved it deterministic before your review named the cause.

Rebased onto current dev (your Demo B topology restore + the schema amendment merged mid-cycle): clean replay, no seam collision — Demo B consumes the reconciler directly at the app layer; the tool's holder-seam contract sits a layer down and composes. One upstream consistency touch rides along: the ADR §2.2 vocabulary sentence now says tools speak the executable window | topology SSOT (the old "tools expose the capability vocabulary" wording is exactly the drift this convergence removed — this PR falsified that sentence, so this PR fixes it).

Evidence at head: the complete affected parity surface — worker 25/25, store 12/12, server 3/3, OpenAPI compliance + tier fixture, GuideToolParity, and the untouched reconciler suite: 94 passed. PR body rewritten to the honest contract throughout.
