WireMesh v0.10.2

WireMesh v0.10.2

Patch release: closes BACKLOG item 5 — the controller's Retire{0} wedge (Phase B / S3, PR #80).

Fixed

• controller: a rotation tracker seeded from a key snapshot with no active row got prior_active_epoch = 0; once promoted it yielded Retire{0} on every tick, Db::retire_epoch's CAS matched nothing forever, and the stale tracker silently cost the next rotation its first EpochAck (falling back to the 90s grace promote). prior_active_epoch is now Option<u32> end to end, the coercion is gone from all three seed sites (drive_rotation_for, sweep_rotations step 2, and the Sync.Report ack path via the hoisted seed_and_record_epoch_acks), and decide yields the new RotationDecision::Finished — the tracker clears with no DB call.

Evidence

• Full wiremesh-controller suite green (47 targets); 54 lib tests incl. five new pins.
• Falsification: each seed site's .or(Some(0)) restored in turn turned exactly its own test red (3 runs, 12/12 results), and recorded_session_generation's unrelated .unwrap_or(0) is pinned as not-a-seed-site.
• Clippy identity diff vs main: no new diagnostics.

Unchanged

Automatic key rotation stays off by default. This was hardening, not a timer gate; BACKLOG item 9 (the gateway rotation wedge, PR1/B2) is the remaining code gate, and the timer stays off pending R2/R15 (Phase C).
