| 8.14 `[D:8.4,8.5,8.8]` | **IN PROGRESS.** Pure Go queue domain enforces one active ticket per verified player, 10 s heartbeat/30 s expiry, retry-safe create/heartbeat/cancel and deterministic candidate projection | `server/domain/queue.go` has adversarial ownership/expiry/idempotency tests; PostgreSQL transaction adapter, Redis candidate index and cache-loss repair remain |
| 8.15 `[D:7.8,8.3]` | **IN PROGRESS.** Pure Go probe validation treats Steam location as opaque, requires nonce/freshness/region and server-computed RTT, and implements discrepancy quarantine/release | `server/domain/probes.go` and adversarial fixtures cover stale/wrong/forged evidence, the 25 ms/30% threshold, three-sample quarantine and five-clean release; Steam coordinator and regional probe adapters remain |
| 8.16 `[D:8.14,8.15]` | **IN PROGRESS.** Pure Go candidate/team selection implements the <=100 ms ceiling, pairwise widening tolerance, anchor inclusion, deterministic set/region scoring and balanced team partitioning | `server/domain/matcher.go`, `teams.go` and adversarial fixtures cover no-common-region, tolerance boundaries, lexical ties, mean-rating balance and input-order independence; queue-backed candidate loading and full population fixtures remain |
| 8.17 `[D:8.14,8.16]` | Ten-second proposal to **every selected human**: ranked 6; casual largest compatible 6→2 after 60 s with disclosed teams/bots; apply exact decline/timeout/no-show cooldown and queue-precedence rules | Allocation starts only after selected humans accept; 2–5-human casual is reachable; accepter timestamps restore exactly; ranked pre-match no-show has cooldown but no rating loss |
| 8.17 `[D:8.14,8.16]` | **IN PROGRESS.** Pure Go proposal policy sends a 10-second response window to every selected human, requires unanimous acceptance, applies exact decline/timeout cooldowns and ranked escalation | `server/domain/proposal.go` and adversarial fixtures cover partial/unanimous response, expiry, replay/conflict and ranked six-player/cooldown rules; casual 6→2 composition, queue precedence and allocation integration remain |
| 8.18 `[D:8.5,8.14,8.17]` | Horizontally replicated matcher: Redis candidates, then PostgreSQL serializable proposal/participant fence, then cache cleanup/repair | Forced loss of the last acknowledged Redis write, retries, worker death and failover cannot claim a player into two proposals/matches |
| 8.19 `[D:8.18]` | Casual policy: proposal composition above; >=1 human/team, exhaustive rating-balanced teams, bots after 60 s, opt-in kickoff-only backfill, 30 s reconnect and defined backfill/casual penalties | Every 2–6-human shape is tested; no mid-play replacement; declined/backfill participant gets no excluded rating/cooldown; original leaver gets only documented outcome/cooldown |
| 8.20 `[D:8.18]` | Ranked policy: exactly six verified solo humans, no bots/backfill, only `ArenaRegistry.random`; define initial no-show, proposal timeout and reconnect/abandon transitions | Ranked rejects parties/bots/backfill/elevated arenas; every pre-live failure returns five innocent players with original precedence and applies no rating |
