+## 2026-06-21 (cont.³⁰) — UNBLOCKED the ractor-actor path (supervisor) — stale "BLOCKED" was a Cargo.lock pin, not a fork bug
+
+**Main thread (Opus), self-directed ("continue").** Chasing the cheapest REAL OUT-leg progress, found `lance-graph-supervisor/Cargo.toml` documented a hard `BLOCKED (2026-06-14)`: "ractor fork ~2 commits behind upstream, non-exhaustive `MessagingErr::Saturated` match, `--features supervisor` will NOT compile." **That note is STALE — verified + fixed:** (1) `/home/user/ractor` (= origin/main, 0 ahead) already has `2bc7819 fix: handle MessagingErr::Saturated at all three match sites`; the enum is NOT `#[non_exhaustive]` and `derived_actor.rs` handles all 4 variants; `cargo check -p ractor --no-default-features --features tokio_runtime` is green. (2) The supervisor build still failed only because `Cargo.lock` pinned a PRE-fix git rev (`3f86d0a`, the merge commit before the all-sites fix). `cargo update -p ractor` advanced it `3f86d0a → f4c474f4` (fixed main); **`cargo check -p lance-graph-supervisor --features supervisor` now compiles clean** (verified, warnings only — callcenter's lance/datafusion are optional + off, so the build is light, no disk blowup). Net: the ractor-actor path (the **mailbox-as-owner substrate the OUT-leg S4/run-NaN depend on**) is OPEN. Committed: Cargo.lock (ractor rev), supervisor Cargo.toml (BLOCKED→RESOLVED comment). This is the first real unblock of the OUT-leg without needing the heavy planner build or symbiont. Rides a PR on jirak.
 ## 2026-06-21 (cont.²⁹) — OUT-leg wiring PLAN authored (S2/S3/S4/run-NaN), grounded not stubbed
 
 **Main thread (Opus), self-directed.** Operator: "all" (close the 4 OUT-leg seams the census found unconsumed). Read the actual surfaces (`orchestration.rs` OrchestrationBridge/StepDomain::Kanban; `soa_view.rs` MailboxSoaView/Owner — note `qualia()` is DEFERRED at :157 "add when first consumer needs it"; `scheduler.rs`). **Finding: every seam's *consumed* impl lives in a disk-heavy consumer crate (planner/shader-driver/callcenter pull lance+datafusion ≈14–18 GB) or in `symbiont` (cognitive-compilation session active).** Manufacturing contract-side test-only stubs (a `KanbanBridge` nothing calls, a `qualia()` nothing consumes) would re-earn the codex #572 overclaim correction ("handler exists ≠ seam consumed"). So the honest deliverable is the **file-level execution spec**, not churn: `.claude/plans/capstone-out-leg-wiring-v1.md` — per seam the enabler + consumer site + test + blocker, sequenced (S4 Kanban-arm → S2 qualia()+shader loop → S3 callcenter LanceVersionScheduler → run-NaN symbiont). Decision B preserved throughout (no `UnifiedStep` field). Gate = disk headroom + symbiont coordination, not design. Registered in INTEGRATION_PLANS. Doc-only; zero overlap. Rides a PR on jirak.
