SUBSTRATE-ENDGAME-RUNTIME-VIEW.md — runtime slice mirror of OGAR master

Tailored cross-repo view onto the substrate-b endgame architecture from lance-graph's runtime-side perspective.

Why this PR

The full architectural endgame doc lives in AdaWorldAPI/OGAR/docs/SUBSTRATE-ENDGAME.md (1345 lines, five-rooms forward-looking). Future lance-graph sessions need a navigation aid that highlights the runtime-side slice without requiring a full read of the OGAR master.

What this view covers

  • Room 1 (today): lance-graph-contract, lance-graph-ontology, lance-graph-callcenter (commit_event sibling — PR feat(callcenter): LanceMembrane::commit_event — action-commit sole-writer sibling (gate 1) #467 merged), lance-graph-planner::temporal (PR feat(planner): temporal — the deinterlace engine (epistemic policy + two causal axes) #468), supervisor, cognitive-shader-driver.
  • Room 2 (migration scaffold): Kanban polyglot work-item trait, HTTP-sidecar bridge, §14 oracle harness, optional BEAM bridge — the runtime pieces that enable per-actor graduation from migration form (HTTP / BEAM / interpreter / CRuby) to native Rust.
  • Room 3 (OP-as-operator-pane): callcenter actors per OGAR Class, version_watcher push stream to OP's Hotwire UI, RubiconWriter Phase 2 dynamic regeneration for operator-edited Workflow rows.
  • Room 4 (visualization): OpenTelemetry exposition + cognitive-event-row stream + actor-tree topology API as data sources for Grafana/OP-native/sexy tiers.
  • Room 5 (SDK endgame): stable public API + SemVer pinning + runtime getting-started + reference deployment.

Cross-references

  • Master: AdaWorldAPI/OGAR/docs/SUBSTRATE-ENDGAME.md.
  • Backward-looking: AdaWorldAPI/OGAR/docs/ARCHITECTURAL-DECISIONS-2026-06-04.mdADR-008 (commit_event), ADR-009 (temporal two-axis), ADR-018 (Kanban polyglot) are the lance-graph-touching decisions.
  • Companion: AdaWorldAPI/openproject-nexgen-rs/docs/SUBSTRATE-ENDGAME-NEXGEN-VIEW.md (pair view from nexgen perspective).

Open items lance-graph owns

  • Cross-server HLC merge policy (deferred body work on QueryReference.hlc_tick).
  • Work-item-form trait + per-actor registration (Room 2 primary).
  • HTTP-sidecar bridge (Room 2 first variant).
  • §14 oracle harness (record-replay infrastructure).
  • RubiconWriter Phase 2 (LanceMembraneWriter + KvLanceWriter).

Pure docs

Navigation aid; no code or runtime changes. Decisions stay authoritative in OGAR.

Tailored cross-repo view onto the substrate-b endgame architecture
from lance-graph's runtime-side perspective. Master doc lives in
AdaWorldAPI/OGAR/docs/SUBSTRATE-ENDGAME.md (five-rooms forward-looking
architecture, 1345 lines). This view focuses on:

  - Room 1: lance-graph-contract, lance-graph-ontology, callcenter
    (commit_event sibling — PR #467, merged), planner::temporal
    (PR #468), supervisor, cognitive-shader-driver
  - Room 2: Kanban polyglot work-item trait, HTTP-sidecar bridge,
    §14 oracle harness, optional BEAM bridge
  - Room 3: callcenter actors per OGAR Class, version_watcher push
    stream, RubiconWriter Phase 2 dynamic regeneration for OP's
    Workflow table
  - Room 4: OpenTelemetry exposition, cognitive-event-row stream
    for sexy-tier viz, actor-tree topology API
  - Room 5: stable public API + SemVer, runtime getting-started,
    reference deployment

Plus cross-references to OGAR's ADR doc (ADR-008 commit_event,
ADR-009 temporal two-axis, ADR-018 Kanban polyglot are lance-graph-
touching decisions) + companion runtime references + open items
lance-graph owns + compact priority map.

Pure docs; navigation aid for runtime sessions picking up the
endgame architecture without re-reading the full OGAR master.
