build: unblock --features supervisor (stale ractor Cargo.lock pin; fix already on main)

[AdaWorldAPI]

Unblock the ractor-actor path — stale lock pin, not a fork bug

Hunting the cheapest real OUT-leg progress, found lance-graph-supervisor/Cargo.toml carried a hard BLOCKED (2026-06-14): "ractor fork ~2 commits behind, non-exhaustive MessagingErr::Saturated match, --features supervisor will NOT compile." That note is stale — verified and fixed:

1. The fix is already on AdaWorldAPI/ractor main. /home/user/ractor (= origin/main, 0 ahead) has 2bc7819 fix: handle MessagingErr::Saturated at all three match sites; MessagingErr is not #[non_exhaustive] and derived_actor.rs handles all four variants. cargo check -p ractor --no-default-features --features tokio_runtime is green standalone.
2. The build failed only on a stale Cargo.lock pin — 3f86d0a (the merge commit before the all-sites fix). cargo update -p ractor advanced it 3f86d0a → f4c474f4 (fixed main).
3. cargo check -p lance-graph-supervisor --features supervisor now compiles clean (verified — warnings only; callcenter's lance/datafusion are optional and off under this feature, 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, unblocked without the heavy planner build or symbiont.

Changes

• Cargo.lock — ractor 3f86d0a → f4c474f4
• crates/lance-graph-supervisor/Cargo.toml — BLOCKED → RESOLVED (with the verified explanation)
• .claude/board/AGENT_LOG.md — cont.³⁰

📝 Walkthrough

Walkthrough

Two metadata files are updated to reflect resolution of a previously blocked ractor supervisor build. The Cargo.toml comment for lance-graph-supervisor changes from BLOCKED (2026-06-14) to RESOLVED (2026-06-21), and a new entry is prepended to AGENT_LOG.md documenting that the block was caused by a stale Cargo.lock pin rather than a missing upstream fix.

Poem

🐇 The lock file was stale, the build wouldn't start,
A ghost of old revisions haunting the cart.
One cargo update, the pins fell in place,
MessagingErr::Saturated found at last in the base!
BLOCKED turns RESOLVED — what a hop-tastic day,
The supervisor compiles and the rabbits can play! 🎉
