- Around line 30-51: Update queryContext and setBlockTime to validate that the
existing query context contains a block with a bigint secondsSinceEpoch before
replacing it, and throw an error if that shape is missing or invalid. Preserve
the current block fields while updating only secondsSinceEpoch, so renamed
simulator internals fail loudly instead of silently leaving the clock unchanged.

🔴 blocking: the two new sentinel circuits (and the three whose proving cost changed: _createProposal, assertProposalActive, getProposalStatus) carry no @circuitInfo k=…, rows=…. The library applies that tag throughout — Signer, and every token / access / security module. Unblocked by annotating the 2 new + 3 modified circuits; a module-wide backfill (0/17 today) can ride with the deferred multisig PR.

🔴 blocking: both exported ledger fields are undocumented. NonFungibleToken.compact:99-115 is the convention — @description plus @type lines for key and value. Worth stating here: _nextProposalId is a monotonic id source that is read back (so ids are never reused, and that read-back is what serializes concurrent creates), and _proposals is keyed by it and stores the overlaid state encoding. Both are readable off-chain without a proof, so integrators consume them directly.

🔴 blocking: RecipientKind and Recipient (line 60) are undocumented, while ProposalStatus and Proposal got thorough blocks in this PR. RecipientKind should say what each variant means and which rail accepts it — toShieldedRecipient rejects UnshieldedUser, toUnshieldedRecipient rejects ShieldedUser, and that mismatch is exactly the hazard _createProposal warns about. Recipient should state that address is raw 32 bytes whose interpretation depends on kind.

🔴 blocking: createShieldedProposal has no doc comment, so this PR adds a required parameter to an integrator-facing circuit without stating its units (seconds since the Unix epoch), its constraints (must be in the future, must exceed the reserved sentinel range), or that the preset imposes no upper cap. The module documents all of it, but the preset is what dApps call. Unblocked by documenting expiry; the preset's other missing docs are pre-existing and out of scope here.

❔ question (non-blocking): _approveProposal (line 130) pins _proposalApprovals.member(id) == false on the first approval, so two first approvers of one proposal collide on that read as well, independently of the _approvalCount cell. Is that worth folding into the same fix? Flagging it so the approval-count refactor removes both collision points rather than one.
added by claude (dev3-midnight-basic-review)

🔵 followup (pre-existing, for the deferred multisig refactor): _approveProposal line 136 does getApprovalCount(id) + 1 — a read-modify-write on _approvalCount[id]. The read pins the old count into the transaction, so two signers approving the same proposal in one block conflict: the loser is rejected at inclusion and has to rebuild, re-prove and resubmit. Concurrent approval is the normal multisig flow, and the same pinned read makes executeShieldedProposal conflict with a late approval landing in the same block.
The per-signer approval inserts are blind per-key writes and never conflict, so the count cell is the only collision point. One direction: drop _approvalCount and prove the threshold at execute time from the per-signer entries (K membership checks over caller-supplied approvers).

🔵 followup: the approval-concurrency limitation above isn't documented anywhere in the preset. There is a convention for this — ConfidentialFungibleToken.compact:163 carries @warning Known limitations. / Concurrency. Two transfers to the same recipient in the same block conflict. Documented limitation; acceptable for the v1 target use case. The header here documents the getCaller / contract-signer limitation at length but is silent on approvals. Worth writing down even while the fix is deferred.

🔵 followup: lapsed proposals have no cleanup path. _cancelProposal routes through assertProposalActive, which rejects once the deadline passes, and there is no _proposals.remove, so every expired proposal keeps its entry and its original deadline forever and this map grows monotonically. The struct docs explain that the retained deadline is what tells a reader when it lapsed — worth stating the consequence too: no pruning circuit exists, growth is unbounded, and a consumer that needs cleanup must compose it. Adding a prune circuit is a separate design decision, not this PR.

There was a problem hiding this comment.
⚪ nitpick: the breaking changes aren't marked, and this file uses a **Breaking:** prefix elsewhere (see the _isInitialized entry). Three integrator-facing breaks here: Proposal.status (enum) → state: Uint<64>, the new required expiry parameter on _createProposal / createShieldedProposal, and getProposalStatus returning Inactive instead of reverting for a missing id.

⚪ nitpick: this reads awkwardly, and it states the comparison backwards from the code — blockTimeLt(state) is blockTime < state, so the subject is the block time, not state. It also contradicts the list just above it, where state is sometimes a sentinel rather than a deadline. Suggested rewrite:
@warning In the deadline range, `state` marks when a proposal STOPS being
executable, not when it starts: it is executable while `blockTime < state`
and inert once `blockTime >= state`.

⚪ nitpick: worth one line here on how this failure differs from a state conflict. A conflicting read is transient — rebuild against fresh state, re-prove, and the transaction lands. proposal expired at inclusion is terminal: an integrator retry loop that treats all rejections alike will re-prove a dead proposal forever.

⚪ nitpick: assert the exact value instead of the negation — toEqual(contract.executedState()) pins which sentinel was written, where .not.toEqual(EXPIRY) would also pass for any other value.

⚪ nitpick: state = 0 is the one reserved value these specs never decode — the group covers the sentinel forge (1) and backdated deadlines (> 2). forceProposalState(id, 0n) should read Expired and fail assertProposalActive with proposal not active (the sentinel check trips before the expiry one). One test completes the blast-radius set and pins which message that corner produces.

⚪ nitpick: the rejections at 0 / 1 / 2 are pinned, but the smallest legal expiry is never accepted anywhere — the lowest accepted value in the suite is NOW + 1 (1,000,001). setBlockTime(2) plus create(3) would pin the reserved range as exactly {0, 1, 2} from the acceptance side too, so a later widening to >= couldn't slip through on that side.

⚪ nitpick (if-minor): one line each pointing at Proposal.state's encoding would let an off-chain reader decode the field without opening the module. Low priority given the preset carries no docs today.

Looking good @andrew-fleming! Left some blockings, questions and nitpicks comments. I'm still running the live testing locally.

Confirmed all tests run successfully on a local live node on my end, Great work @andrew-fleming! 👌 |

ShieldedMultiSig will be refactored separately. This PR proposes to just include minor adjustments to the preset in order for tests to pass, so it's technically correct just not complete atm. To be explicit, the following items are deferred to a separate PR specifically targeting shielded multisig:
