refactor(app): ZEB-1046 route reset-lifecycle e2e onto dfrost_complete_threshold_sign_core - #788
Conversation
…e_threshold_sign_core Convert community_dfrost_reset_e2e's flow1/flow2/flow3 threshold-sign completion off the hand-mirror (contribute_round2 + maybe_complete_reset_response) onto the production dfrost_complete_threshold_sign_core extracted in ZEB-1040, so every reset-lifecycle e2e now runs the real completion path. - New complete_reset_response_via_core helper (the round-1-already-landed completion half); drive_reset_response now fires round-1 then delegates to it. Both drive the core via node.handles + the InsertBothAuthor seam. - Membership timelines rebased onto real wall-clock (the core stamps responses with SystemTime::now() and evaluate_reset_phases gates on absolute windows): flow2 veto at real-now; flow3 endorse+consumed and flow1 disaster+consumed BACKDATED so authorized_at lands before the core's real-now stamps (Endorse/Veto gate [t0, window]; Consumed gates wall >= authorized_at, HLC-monotonic per authoring device). - Deleted maybe_complete_reset_response (now unused). contribute_round2 stays: the failed-author M5 test still uses it as a round-2 share producer. Net -333 lines of drift-prone mirror. Gates: fmt + clippy --all-targets -D warnings clean; reset-e2e 8/8 stable over repeated runs; test-select --context task 1203/1203.

One flow-3 comment has outdated timing and completion wording, but it has no runtime impact, so no actionable merge-blocking risk remains after normal review. Sequence Diagram(s)sequenceDiagram

the round-2 completion path: describe now_ms as derived from real_now minus 60

Consumed ceremony instead of manual round-2 completion.

…nd 1) The ZEB-1046 conversion left two flow3 comments describing the retired setup: "now_ms is still 10_000-ish" (it now holds real_now - 60_000) and "manual round-2 completes it" (the Consumed ceremony now completes through complete_reset_response_via_core).

Closes ZEB-1046 — the ZEB-1040 follow-up. Routes the reset-lifecycle e2e (
community_dfrost_reset_e2e.rs) off the hand-mirrored threshold-sign completion onto the productiondfrost_complete_threshold_sign_corethat ZEB-1040 extracted, so every reset flow now exercises the real completion path instead of a parallel copy that could drift fromlib.rs.What moved onto the core
Four ceremonies across three lifecycle tests:
flow2_disaster_vetoedflow3_cooperative_endorseflow1_disaster_to_completionThe round-2 + canonical-set aggregate + the
SignPurpose::ResetResponsecompletion arm now run the extracted IPC code. The membership author crosses the layer boundary through the existingInsertBothAuthorseam (ResetResponseAuthor), exactly as the ZEB-1040 tests already do.flow4(joiner bootstrap) drives no threshold-sign ceremony and is untouched.Helper shape
complete_reset_response_via_core(new): the "round-1 already landed" half — alice posts her round-2 share (canonical set not yet complete → no aggregate, no author), then bob crosses threshold + authors + clears his session. Used directly by the Consumed sites (whose round-1 is auto-driven by the reset orchestrator) and by…drive_reset_response(rewritten): fires round-1 viainitiate_reset_response_ceremony, waits for convergence, then delegates tocomplete_reset_response_via_core. Its signature dropped the params the core reads from the log itself (pub_key_package,key_pkg_*,members,at_ms) and thestateparams (the seam owns insertion now); it takes&OrchestratedNodefor.handles.maybe_complete_reset_responsedeleted — its only callers are gone.contribute_round2stays: the failed-author M5 test (reset_response_completion_failed_author_leaves_session_zeb1040) still uses it as a round-2 share producer.Real wall-clock rebasing (the fiddly part)
The core stamps every authored response with a real
SystemTime::now()HLC, andevaluate_reset_phasesgates responses on absolute wall-clock windows — so the hand-mirror's synthetic ~10_000ms timelines had to be rebased. The exact rebasing is per-verdict, driven by which gate applies:[t0, response_window_end]→ base at real-now (flow2; flow3's endorse).wall ∈ [authorized_at, authorized_at + RESET_AUTHORIZED_LAPSE_MS)→ the authorization must land at/before real-now:max(endorse_wall, t_q)): backdated 60s sot_qsits below the real-now endorse stamp, makingauthorized_at = endorse_wall; the Consumed response — authored by the same device, hence HLC-monotonic and strictly later — always clears the gate. Without the backdate a sub-100ms run stamps Consumed beforet_q = base_ms + 100and misses it — caught as a 1-in-5 flake during convergence and fixed deterministically (10/10 on the isolated flow after).deadline + FINALITY, ~72h out): backdated byveto_window + finality + slacksoauthorized_at ≈ real-now, where the core's Consumed stamp lands.Only
flow1runs a ceremony that needs noinstall_pub_key_package— its old committee never signs (the reset lapses to Authorized with no veto), and the sole Consumed ceremony runs on the successor-DKG committee, which already carrieslocal_pub_key_package. The old-committee ceremonies (flow2 veto, flow3 endorse) getinstall_pub_key_packagebecause theseed_old_committeedealer shortcut leaves it unset.Gates
