fix(multisig-client): prune executed proposals from the cache on sync#405WiktorStarczewski wants to merge 5 commits into
Conversation
syncProposals merged the GUARDIAN response into a local Map that was never pruned, so a proposal the server dropped after execution kept being returned as pending. A co-signer who did not execute the tx saw the executed proposal stuck as pending forever. Rebuild the cache from the (authoritative) GUARDIAN response on every sync and skip proposals already consumed by the committed account nonce, mirroring the Rust client's list_proposals.
… filter Address review: the client-side nonce staleness filter assumed the next-nonce convention and would evict freshly-created proposals under the examples/web same-nonce convention. Nonce-based hiding is a display concern the example apps already handle in filterVisibleProposals, so leave it to callers and keep the client convention-agnostic. Reconcile the cache in place against the authoritative GUARDIAN response instead of wholesale-replacing it: snapshot the ids known before the round-trip and prune only those the server no longer reports, so a proposal created/signed/imported concurrently during the awaits is not dropped.
…ariant Add a test that a proposal GUARDIAN still reports survives the reconcile (catches an unconditional-delete regression), and make the doc comment state explicitly that the import-flow guarantee is transitive through the creator's createProposal push, not the importer.
… parity Address review: document that listProposals() returns the last sync's reconciled set (not an ever-growing history), reword the README sync section to say it reconciles/prunes, and note the nonce-filter TS/Rust surface difference is intentional (the shared client cannot assume a single nonce convention).
Address review: track the ids GUARDIAN returned on the last sync and prune only those it now omits. A proposal the client created or imported but that GUARDIAN has not yet reported (e.g. read-your-writes lag right after createProposal, or an imported-but-not-yet-synced proposal) is no longer evicted. Subsumes the earlier pre-await snapshot guard.

Document the pruning eligibility condition.
This text implies that every cached proposal absent from GUARDIAN is pruned. syncProposals only prunes proposals that GUARDIAN reported during a previous sync. Locally created or imported proposals remain cached until GUARDIAN first reports them.

Thanks for this. Pruning only ids GUARDIAN previously reported is the right invariant, and TS-only is the right scope — Rust list_proposals is fetch-fresh.
Two things to fix before merge:
1. Verify failure mid-loop leaves an unprunable proposal. verifyProposalMetadataBinding is awaited inside the loop, so [P_ok, C_malformed] caches P and throws before lastReportedProposalIds is updated. P is then “never reported” and no later empty sync can prune it, the same forever pending shape as #404. Verify into a temp structure; merge and prune only once the whole response validates.
2. Overlapping syncs can delete a live proposal. The prune loop reads lastReportedProposalIds at apply time(multisig.ts:597). Sync A fetches [P] and stalls in verify, createProposal(Q) caches Q, sync B fetches [P, Q] and completes, then A applies {P} and deletes Q. Prune turned a harmless overlap into a destructive one, so in-flight dedupe belongs in this PR.

What
syncProposals()now reconciles the local proposal cache against the (authoritative) GUARDIAN response on every sync — proposals GUARDIAN previously reported and now omits are pruned — instead of only ever adding to a Map that was never cleaned up.Why
The Map was merge-only. After a proposal is executed, GUARDIAN stops returning it (the server keeps only pending proposals). The executing co-signer's browser had updated its own cache while executing, but every other signer's browser silently ignored the now-empty response and kept the executed proposal pinned as pending forever (stuck at, e.g., 1/2).
How
lastReportedProposalIds) and prune only those it now omits. A proposal GUARDIAN has never reported to this client — freshly created (before GUARDIAN's read-your-writes catches up) or imported-but-not-yet-synced — is never a prune candidate, so those flows keep working; a proposal GUARDIAN reported and then dropped (executed / abandoned) is pruned.noncefield has no single cross-app convention (this repo'sexamples/webstores the pre-execution account nonce;examples/_shared/multisig-browserand the Rust client use the next nonce), so filtering on it in the shared client would evict live proposals for one of them. Nonce-based staleness hiding stays where it already lives — the callers'filterVisibleProposals.Tests
Three new
syncProposalstests (each mutation-checked to fail against the bug it guards):Full package suite green (426 tests),
tsc --noEmitclean.Release / semver note
This changes the observable output of
syncProposals()/listProposals()(they no longer retain proposals GUARDIAN has dropped). It fixes buggy behavior, and the in-repo example consumers already re-derive their visible set each sync, so no consumer regression is expected — but the release carrying it should flag this (a minor bump, or an explicit release note). No version bump is included here since versioning is a separate release commit.Notes for maintainers (out of scope for this PR)
examples/web/src/lib/multisigApi.tsuses a different proposal-nonce convention (proposalNonce = currentAccountNonce, filternonce < accountNonce) thanexamples/_shared/multisig-browserand the Rust client (+1,nonce <= accountNonce). Worth reconciling separately.syncProposalscalls (return the pending promise if one is running) to avoid a transient prune/keep blip when overlapping syncs race, and to cut redundant round-trips.Closes #404
