Seal the capstone OUT/IN-leg public surface + mixed-trigger e2e test

[AdaWorldAPI]

What I chose & why

S3-live (wiring a real lance VersionedGraph::versions() stream) is what I most wanted to finish — but it's disk-walled in this environment (~11 GB free vs ~14–18 GB for the lance/datafusion build; ENOSPC'd twice). Its proper home is the symbiont golden-image harness, which already pulls lance-7, wherever that builds with real disk.

So the feasible completion of the arc: seal the capstone's public surface. The five OUT/IN-leg drivers shipped across #576–#580 were reachable only by module path — lib.rs re-exported just KanbanActor + KanbanMsg. This promotes the consumer surface so the live S3 consumer can use lance_graph_supervisor::{...} directly when it lands.

Changes

• lib.rs — re-export deliver_kanban_step, drive_mul_advance, drive_scheduled_tick, drive_version_tick, run_to_absorbing, KanbanRouteError.
• +1 test (15 total green) — mixed_triggers_compose_on_one_owner_s2_gate_then_s3_ticks, the capstone integration: the S2 MUL gate takes the first Rubicon step (Flow qualia → Planning→CognitiveWork) and S3 version ticks (run_to_absorbing) carry the rest to Commit. Proves the two different triggers compose on one mailbox-as-owner — no panic, no spurious rejection, lands absorbing.

clippy + fmt clean; light build (no lance/datafusion, no disk gate).

Remaining (disk-gated, not here)

S3 live versions() source + S2 shader-driver per-row loop — both need the heavy lance build, to be done in the symbiont harness where it fits.

Warning

Review limit reached

@AdaWorldAPI, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 53 minutes and 16 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses rolling per-developer review limits. Reviews become available again as older review attempts age out of the rolling limit window.

📝 Walkthrough

Walkthrough

Expands the lance-graph-supervisor crate's public API by adding re-exports of driver/routing functions (deliver_kanban_step, drive_mul_advance, drive_scheduled_tick, drive_version_tick, run_to_absorbing) and KanbanRouteError in lib.rs. Adds an end-to-end integration test composing S2 and S3 triggers on one KanbanActor owner and verifies the full Rubicon phase progression to Commit. Updates the agent log accordingly.

Changes

KanbanActor Public Surface Seal

Layer / File(s)	Summary
Expanded kanban_actor public re-exports crates/lance-graph-supervisor/src/lib.rs	Replaces the minimal pub use kanban_actor list with a broader export including deliver_kanban_step, drive_mul_advance, drive_scheduled_tick, drive_version_tick, run_to_absorbing, and KanbanRouteError, alongside the existing KanbanActor and KanbanMsg.
Mixed S2/S3 trigger integration test crates/lance-graph-supervisor/src/kanban_actor.rs	Adds mixed_triggers_compose_on_one_owner_s2_gate_then_s3_ticks: spawns a KanbanActor backed by TestBoard, drives S2 via drive_mul_advance asserting a CognitiveWork move target, then advances S3 via run_to_absorbing asserting Evaluation→Commit arc, and confirms final KanbanMsg::Phase RPC returns Commit.
AGENT_LOG update .claude/board/AGENT_LOG.md	Prepends a 2026-06-23 entry recording the sealed OUT/IN-leg public surface and the new mixed-trigger test.

Poem

🐇 The kanban lanes are sealed and bright,
Re-exports bloom in public light.
S2 gates first, then S3 ticks—
Through CognitiveWork the actor flicks.
From Evaluation to Commit we go,
A hopping trail through states we know! 🎉
