Refresh roadmap authority to active dependency graph

[briansrls]

Summary

• Replace the historical roadmap ledger with 44 remaining committed deliverables and 42 explicit product-dependency edges across eight active chains.
• Keep accepted, completed, and superseded history—and mutable PR, CI, session, attempt, and lease state—out of authority.
• Use TicketLine throughout the active graph with explicit ManualAcceptance, truthful unsigned state, and deliberate 13 small / 15 medium / 16 large sizing.
• Keep automatic admission as future work, document the existing manual dispatch path as live and outside this slice, preserve independent product dependencies, and constrain Ready to scheduling only after accepted parents and the typed identity join; keep SCM/source-intent and other parked plans reachable only as non-dispatchable documentation context.
• Derive acyclicity mechanically from the graph and add executing REDs for completed, accepted, and superseded row re-entry.
• Preserve the namespace, P-derive, observation, placement, v1 deletion, shell, roadmap-runtime, and fleet/hygiene critical chains, including their cross-chain prerequisites.
• Preserve the DESIGN-mandated terminal path from interpreter deletion to repository-wide zero hand-maintained Rust, including src/v1, stage0, and dag/tools; emitted Rust realizations and cited external trust remain explicitly outside that terminal row.
• Regenerate ROADMAP.md exclusively from the .dag authority and update only its direct projection witnesses.

No mutable open-PR mapping is copied into the roadmap or this handback; active deliverables are identified by durable node IDs and carrier documents.

Validation

• exact CI-grain v1-compiler release-bin build: PASS
• all 19 roadmap authority witnesses: PASS
• all 48 direct roadmap page/row/lamp and doc-reachability witnesses: PASS

The branch was synchronized once to current main 17812970a9fe8a1559879241601a30cf2e6c6bc7 as authorized. Full hosted CI and fresh review coverage are rerunning on the corrected head. No merge is requested.

Addressed review 43881 on head c590c7f: added active terminal v1-zero-hand-maintained-rust as a ManualAcceptance TicketLine, dependent on v1-interpreter-delete and carried by the existing dag/gunbc/v1_deletion_plan.dag authority. Its boundary requires every remaining src/v1/stage0 Rust source to be emitted from cited .dag models or deleted, with a roster RED and execution handback; emitted Rust realizations and external trust remain out of scope. The v1 critical-chain witness now executes the terminal edge, and ROADMAP.md was regenerated. Local release build, 17/17 authority claims, 11/11 direct projection/reachability claims, regen, and fixed point pass. — sent from nimble-fox-152

Addressed review 43888 on exact head 6168bf0a05:

• Restored dag-scm-design.md, dag-scm-product-strategy.md, and node-subtree-visibility-grants.md as reachable, explicitly non-dispatchable parked context; no speculative SCM TicketLines or historical 2-scm-* rows were restored.
• Removed all 11 false roadmap-runtime-identity-join edges from independent product roots. RoadmapEdge now remains product dependency only.
• Added a typed closed RoadmapDispatchGate authority pending the runtime identity/lease join, plus executing REDs proving the gate remains closed, parked SCM carriers cannot become active nodes, and product roots cannot regain roadmap-tool dependencies.
• Regenerated ROADMAP.md; graph is now 43 active nodes / 41 product edges.

Validation on this tree: 19/19 authority witnesses, 48/48 direct projection/reachability witnesses, wet regen, fixed-point regen, and diff check pass. Hosted exact-head build/regen/heal pass; full CI is running.

Addressed reviews 43893, 43894, and 43897 on exact head 6b69f610f3:

• Removed the mechanical coproduct-to-Bool dispatch predicate. The staged authority is now a typed record containing only required_join: RoadmapNodeId, and its witness directly verifies that the named prerequisite is the active runtime identity-join node.
• Corrected the generated preamble: this authority is explicitly not admitted as a live dispatch source until that join is implemented. It makes no claim that today’s belt_dispatch_node, next_spawnable, or manual POST path refuses, and no runtime/spawner code was changed.
• Reworked the active-row integrity helper to consume canonical line_ticket, item_is_done, and signoff_is_present projections instead of directly walking RoadmapItem and Signoff coproducts. The completed, accepted, and superseded planted REDs retain their behavior.

Validation: 19/19 authority witnesses, 48/48 direct projection/reachability witnesses, wet regen, fixed-point regen, and diff check pass. Hosted exact-head CI is running.

Addressed review 43900 on exact head 8b9c60b65e:

• Removed the disconnected RoadmapDispatchGate and its witness entirely. The preamble now says only that automatic admission is future work and truthfully records the existing manual dispatch path as live and outside this model slice.
• Reframed Ready as an operator scheduling override available only after every dependency edge is accepted and the typed identity join succeeds. It cannot bypass an unaccepted parent, missing/mismatched join, dependency refusal, acceptance, or any other refusal.
• Updated the dispatch-consumer boundary and RED so unaccepted parents refuse and Ready is optional scheduling input, never dependency substitution.

Validation: 18/18 authority witnesses, 48/48 direct projection/reachability witnesses, wet regen, fixed-point regen, and diff check pass. Hosted exact-head CI is running.

Addressed review 43903 on exact head 93f37607ad:

• Restored the terminal to repository-wide zero hand-maintained Rust, explicitly including tracked Rust under src/v1, stage0, and dag/tools.
• Kept src/v1/stage0 roster reduction as the first intermediate slice rather than the finish line.
• Updated the terminal RED so any tracked hand-Rust anywhere in the repository without emitted authority and a migration trigger blocks acceptance and reopens the roster.
• Kept emitted realizations and external rustc/std/OS trust out of scope; the existing v1_deletion_plan carrier and dependency edge are unchanged.

Validation: 18/18 authority witnesses, 48/48 projection/reachability witnesses, wet regen, fixed-point regen, and diff check pass. Hosted exact-head CI is running.
