Mythic+ Party Shuffle

v0.4.0 (2026-06-14)

Full Changelog Previous Releases

• chore(openspec): sync specs and archive throttle-resilient-roster-sync
  • New roster-snapshot capability spec (paged, versioned, atomic-replace,
    re-request).
  • comm-protocol: add lean roster entry encoding; late-joiner resync delivers a
    paged snapshot.
  • event-sync-gate: SYNCED converges on the complete paged snapshot.
  • dev-roster-fixture: fake injection sends one spoofed JOIN per fake on the wire.
  • Move the completed change to changes/archive/2026-06-14-...

• feat(comm): lean roster entries + paged ROSTER snapshot (throttle resilience)
  Reduce roster-sync cost under Blizzard's per-prefix addon-message throttle
  (≈10-message burst, then 1/sec, counting messages on every transport).
  • Lean wire entries: drop every specId-derivable field (class/spec/role/
    bloodlust/battleRez) and use short keys; the receiver re-derives them from
    specId via SpecDetails on receipt, with a graceful fallback for an unknown
    specId. ~3x fewer bytes per entry. The specId->{class,spec} catalog moves
    from DevFixture into SpecDetails (single source of truth).
  • Paged ROSTER snapshot: the authoritative roster is sent as versioned pages,
    accumulated by version (newer supersedes, older ignored) and applied as an
    atomic replace only once complete. ROSTER_PAGE_MAX packs a typical roster into
    one logical message (fewest messages = fastest under the throttle); larger
    rosters page. SYNCED converges on the complete snapshot (+ SHUFFLE when the
    snapshot signals one); sticky-synced unchanged.
  • PROTOCOL_VERSION bumped to 2 (old/new clients ignore each other).
  • Fake roster: simulate n registrations joining ~simultaneously — the organizer
    registers each fake locally and sends one spoofed JOIN per fake on the wire,
    so a connected participant receives n real JOINs (faithful, throttle and all).
    Tests: 138/138 (offline lua harness), incl. lean codec round-trip, paging,
    version supersession, atomic completion, gate convergence.

• docs(openspec): capture fake-roster incremental drip in dev-roster-fixture
  Document the realistic injection behavior shipped in v0.3.0: the organizer
  announces a fake-roster change as incremental spoofed JOIN/LEAVE messages
  (one per entry, staggered) instead of a bulk ROSTER snapshot. Updates the
  dev-roster-fixture spec and archives the change.

• chore(openspec): sync specs and archive resync-loading-gate
  • Add event-sync-gate capability spec (SYNCED predicate, loading gate,
    bounded resolution, background keep-alive).
  • Append "Local reset before authoritative repull" to event-reconnect.
  • Move the completed change to changes/archive/2026-06-14-resync-loading-gate.
