id: protocol v1 phase 4 — retention and compaction for the event store (#2036) #3797
Description
Phase 4 of the #2036 protocol v1 synthesis, from the #2034 investigation (§7): pkgs/id event_store today keeps every verified event forever (event_store/mod.rs:4-23 — no TTL/compaction/GC). Implement the first per-class retention/compaction path: live-class segments compact to their checkpoint residue (checkpoint events + hashes remain), durable classes untouched, per the class table in doc/2026-10-29T10-45-00Z_investigation_ephemeral_live_data_retention §3/§7. Hard constraints: compaction must preserve fork proofs and waiting-pool after resolution (event_store/mod.rs:12-22). Acceptance: compaction tests per class; a compacted store still verifies chains and resolves fork proofs; durable-class events are never compacted.

Blocked on #3794's signed session.checkpoint event contract landing; preserve the defined checkpoint residue rather than inventing one. Revalidate #3797/#3794 and ownership before resuming; no source or worktree changes this run.

state: reviewed (coverage loop-back)
Coverage pass 2026-11-03, loop-back review: this issue was re-reviewed (drift / overlap / already-handled / stale / blockers / ordering) so every open issue in the four repos is reviewed and in the system. Verdict: still live; in the system as task 5787 (small_fix, queued, priority 50) in repo-health-code-pilot. Labels audited and synced. If it is already handled at current main, its triage closes it with evidence; if oversized, the triage files the split; blockers belong on this issue.

Resuming task 5787 from the prior verified dependency-gate checkpoint. Fresh GitHub state: #3797 is OPEN with no hard-stop labels; prerequisite #3794 is CLOSED and its implementation PR #4627 is MERGED. This lane will fetch/fast-forward main, verify the checkpoint schema/golden vectors are present, then continue only if the gate is satisfied. Current labels already reflect the claimed state:

Packet defect: phase 4 cannot safely choose events to compact yet. Fresh origin/main (a51be0e) contains the #3794
session.checkpointschema and pinned golden-vector test, and #3794/PR #4627 are closed/merged. However, the #2036 design §4.6 requires compaction to use the channel/session retention policy and phase-2/3-declared metadata. CurrentChainExt/SessionCheckpointcontain no retention class, policy, or expiry. Issues #3795 and #3796 are still OPEN with no linked PRs (#3795 is user/escalated); there is no safe eligible-event classifier. No source edits or tests were made.Disposition: task 5787 blocked as
packet_defect; current lane labels reflect blocked state. Resume after the packet names the retention classifier/policy/expiry contract and dependencies on phases 2/3 are satisfied, then revalidate fresh. Task worktree/home/user/git/fleet/5787is clean onqueue/5787-3797-event-store-retentionat a51be0e.
