v0.6.0-rc12 — catch-up liveness + state-sync hardening

Fixes found during the rc11 soak and an overnight force_state_sync recovery:

• D6 — catch-up pending-capacity wedge (reproduced twice in the field):
  unsolicited far-tip pushes filled pending_payloads (cap 16,384) so the
  solicited tip+1 payload replies were rejected → execution halted forever.
  Solicited replies now bypass the cap.
• D7 — peer-mesh metric blind spot: mesh health now counts inbound
  deliveries and fetch-served payloads, not only proposer broadcasts.
• D8 — state-sync donor decode cap: donor gRPC client raised to 16MiB
  (snapshot chunk 0 is ~7.8MiB at ~2.22M heights; the 4MiB default rejected
  every donor, crash-looping forced syncs).
• D9 mitigation — invalid donor records are skipped: a donor serving a
  truncated/unverifiable block record no longer aborts the anchor fetch;
  min_anchor_agree byte-identical quorum is still enforced. Observed on
  two independent donors at different heights — root cause tracked in
  g1-ceremony/INCIDENT-2026-10-18-rc12.md.
• D5 — sealed DKG dealing files ship in generate-testnet-keys
  (X25519 + XChaCha20-Poly1305, recipient-sealed).

Canary: home-vb validator ran this exact binary (2d5a3b5d…) through a live
force_state_sync recovery before release.

v0.6.0-rc11

G2 post-cutover hardening: state-sync donor-root quorum gate, force_state_sync flag, peer-mesh diagnostics.

v0.6.0-rc10 — G2 candidate

G2 candidate build.

Changes since rc9

• restart_anchor consensus mechanism — coordinated validator set changes restart from a shared parent (R9 rehearsal: add 4→5, remove 5→4, retired-seat isolation all PASS)
• Idempotent journal prune — BlobMissing on an already-absent section no longer panics the voter/resolver (post-G1 3-of-4 stress finding)
• jc-faucet, jc-explorer v2 (archive deep history), jc-status stall alerting

Artifacts

• slay3rd-linux-amd64 — verify with MANIFEST.sha256 before running
• install.sh — sh install.sh fetches + verifies + installs

Post-G1 stress notes

A 3-of-4 config (Akash seat retired) halted 14.4h on 2026-10-14 when a second seat crashed on the prune bug fixed here. See g1-ceremony/INCIDENT-AND-BUGS-2026-10-08.md.
