Release a stuck shield reservation, and let the reader release shields - #171
Reported from an Android phone on Build 187: the "Some payments have unresolved outcomes" warning stayed for hours, the 50,000 sats stayed unshielded, and the user asked for a way to force-clear the reservation.
Why #167 did not clear it. A shield's journal entry released only when settledDeposit answered that its coin was unspent. landedDeposit answers undefined when the indexer read fails, the outpoint does not come back as exactly one coin, the coin is swept or unrolled, or it was spent by anything but a batch the account knows, so one of those kept the entry forever, and the reserved coin also blocks auto-shield (planFor) and renewal. Separately, a coin read that threw (rather than answering undefined) rejected the Promise.all in reconcileJournal, so the settle pass never ran at all.
Automatic release. A shield spends one coin of the wallet's, and a coin can be spent only once, so past the pool's retention plus grace the shield has either landed (coin spent, nothing to re-shield) or never can. A shield entry now releases once past that bound whatever its coin answers, and still drops early when the coin shows it landed. A coin read that fails no longer stops the pass. Payment (note-spend) entries keep their rules, including the batch-count proof.
Manual release. The warning gains "Release reserved shields" behind a confirmation. It releases shield entries older than the grace (15 minutes), at any age past that, and never a payment: a payment released by hand could skip the settle rule's proof that the pool count moved, the guard against a stalled operator view, and a retry on other notes could pay its recipient twice. A payment stays reserved until the automatic rule, which runs every minute, can prove the pool will not include it. A shield younger than the grace stays reserved too, since its post may still be in flight. The result shows in its own dismissible notice, so it stays visible after the warning disappears with the last reservation.
Operator: one slot per coin. Review found that two slots on one deposit coin could share a batch: admission checked spend ids and nullifiers, and a deposit's nullifiers are fresh. A batch that spends one outpoint twice is refused by the network. A released reservation lets an honest client reach this while its first copy is still queued. Refusing the twin at admission was tried first and dropped: admission cannot tell who owns a coin, and outpoints are public, so anyone could queue a slot on a victim's coin and keep the owner refused. Instead run in src/rollup/epoch-operator.ts lets both slots queue and puts only the oldest selectable slot per coin into a batch. Signing already decides ownership: a slot whose depositor does not sign is dropped and the batch rebuilt, and the owner's slot goes next. This takes effect only once the pool operator is redeployed; until then the 15-minute grace keeps the in-flight case out, but not a copy still queued past it.
Model.PoolSpendJournal.tla now counts landings, so NoDoublePayment is the real property: a deposit may land only while its coin is unspent, a note spend has no such bound. The forced release applies to deposits only; PoolSpendJournal_ForceNotes.cfg lets it touch a payment and violates NoDoublePayment. PoolSpendJournal_CoinSpentCheck.cfg is retired (once the coin verdict no longer gates the release, that guard is dead). A false green found while writing it (freed both assigned and UNCHANGED, silently disabling two release branches) is fixed. Settle may also read a deposit's coin as unknown on any pass, which is what reconcileJournal's catch produces, and PoolSpendJournal_UnreadableCoin.cfg shows that keeping the row on that verdict violates NoStrandedReservation. The model's ForceRelease is deliberately looser than the app's (any age, POST in flight included); the README says so and names the operator's coin check as outside the model.
Validation, local, on main e62f3c9: new and updated tests in tor-mutations, private-transport and app-private-build, each red on the previous code: an old shield whose coin verdict is unknown (read fails, swept, spent elsewhere) releases past the window and stays inside it; a coin read that throws does not stop the pass; the banner releases a shield past its grace, keeps a younger one, and never releases a payment at any age; another origin is untouched. Mutations (shield waits for its coin, retention bound dropped, unreadable coin aborts the pass, force frees a payment, force ignores the grace) each fail their test. Six affected suites pass 241 of 241; tsc --noEmit is clean; node tools/check-native-model.mjs matches 127 configurations (base 27,307 states, 6,388 distinct, every action fired). The new operator test queues a squatter ahead of the owner on one coin. On the operator before this PR both slots share a batch and the owner's deposit is dropped with the squatter's; with the change the squatter is batched alone, dropped at signing, and the owner's deposit lands next, spending the coin once. Full suite at 270d840: 1926 tests, 1925 pass; the one failure is the known Linux publication… test under Git Bash tar, which fails identically on the clean tree.
Only a device can confirm: that the reported entry ages out after updating (it should clear within about a minute of opening), that the banner's button reads well on a narrow screen, and that auto-shield then posts the shield.
Summary by CodeRabbit
New Features
Added a confirmation flow for releasing eligible reserved shields. Wallet warnings now distinguish releasable shields from payments, which remain reserved until their status is confirmed.
After a release attempt, the wallet reports what was released, what remains reserved, and any errors, then refreshes its status.
Bug Fixes
Unreadable deposit status checks no longer prevent other wallet entries from being reconciled.
Reserved shields are released according to settlement status and the grace period; payments are not released through this flow.
A shield's journal entry released only when the indexer answered that
its coin was unspent. A coin that was swept, renewed or spent elsewhere,
or a read that failed, answered nothing, so the reservation stayed
forever and auto-shield skipped the coin; a coin read that threw also
aborted the whole settle pass.
A shield spends one coin of the wallet's, and a coin can be spent only
once, so past the pool's retention it has either landed, leaving
nothing to re-shield, or it never can. A shield entry now releases once
it is past that bound whatever its coin answers, and still drops early
when the coin shows it landed. A coin that cannot be read no longer
stops the pass. Payment entries keep their rules.
The unresolved-outcomes warning gains "Release reserved funds" behind a
confirmation. It releases every shield at any age, and a payment only
once it is past the pool's bound and the wallet says no batch carried
it, since a retry on other notes could otherwise pay twice; anything
left reserved says why and, for a payment still in its window, when it
becomes releasable.
PoolSpendJournal.tla now counts landings, so NoDoublePayment is the
real property: a deposit may land only while its coin is unspent, a
note spend has no such bound, and forcing a payment free on age alone
is a counterexample.
A payment released by hand could skip the settle rule's proof that the
pool count moved since the entry was judged, the guard against a
stalled operator view saying a spend did not land. The banner now
releases shields only ("Release reserved shields"); payments keep the
automatic settle rule, which runs every minute. A shield younger than
the grace stays reserved too, since its post may still be in flight
and a retry would put the same coin in a second slot.
PoolSpendJournal.tla limits the forced release to deposits, with
ForceNotes as the mutation that lets it touch a payment.
No actionable comments were generated in the recent review.
Walkthrough
The native journal now uses separate settlement rules for deposits and note spends, and it can release eligible reserved shields. The wallet adds a shield-release confirmation flow. The rollup operator rejects duplicate pending coin spends. The Pool Spend Journal model and TLC configurations now track retries, releases, and payment state.
Changes
Journal Settlement and Shield Release
Layer / File(s)
Summary
Journal settlement and release src/native/mutations.ts, tests/private-transport.test.ts, tests/tor-mutations.test.ts
The journal uses separate settlement checks for deposits and note spends. It adds a deposit-only force-release operation and treats failed deposit lookups as unknown verdicts. Tests cover settlement boundaries and release behavior.
The wallet adds confirmation for releasing reserved shields through the native or private journal. It reports release counts, refreshes wallet state on success, and displays errors.
The operator rejects a spend when its deposit coin matches a pending or inflight spend. Tests verify the duplicate refusal and that the first spend remains pending and lands.
Journal model and TLC configurations spec/tla/PoolSpendJournal.tla, spec/tla/PoolSpendJournal*.cfg, spec/tla/README.md
The model tracks coin spending, releases, retries, and payments. It adds retry and force-release transitions, revises invariants, and updates configurations and documentation.

For a deposit, Verdict returns only "landed" or "nothing". The model cannot represent an unavailable coin verdict for deposits, so Settle never runs the release path that this PR changes.
Add a deposit verdict that can be unavailable. Release a deposit at the retention age whatever its verdict, as SettleProven already requires. Keep the dead guard for note spends.
If the unavailable verdict is added while Settle still gates deposits on dead, the deposit release stays false after retention. SettleProven requires that release, so NoStrandedReservation would fail. This gives the invariant coverage of the PR's recovery path.

Included review availability: This review used your included allowance. Your plan provides up to 1 included review per hour; 0 remain after this review.
Overall: The fix is sound. The deposit-reservation bug is real and the solution — releasing a deposit past the retention+grace window regardless of its coin's answer — is correctly bounded by the coin-spends-once property at the protocol level. The TLA model, test suite, and PR description are all consistent with each other. A few items below need attention before merge.
The old code for a deposit whose coin returned undefined (indexer unreachable, outpoint unknown, swept) fell into the verdict!==false branch and kept the entry forever. The new code is:
undefined (unreadable) → true && within-window → same as false. ✓ (the previous bug)
The final return for note-spends changed from row.coin===undefined&&count===row.batchAt to at-row.createdAt<=TRACKED_MS+graceMs||count===row.batchAt. Semantically identical in the new code path (deposits are handled early), and matches the TLA Settle branch.
A throwing settledDeposit previously rejected the entire Promise.all and silenced the settle pass. The fix is minimal and correct — the caught undefined is indistinguishable from a normal "can't tell" answer, and the time-based window releases the entry eventually regardless.
Note: settledNullifiers (sync, in-memory) is not wrapped. That is appropriate — a sync state read that throws is a programmer error, not a network glitch, and surfacing it is better than swallowing it.
graceMs is always defined on both paths (NATIVE_GRACE_MS / PRIVATE_GRACE_MS, both 900 000 ms). ✓
beforeNativeMutation guards the same coin on future attempts, so after a release a retry is blocked only if the original entry is still present — which it isn't after force-release. A retry on the same coin is what autoShield will do. ✓
released = entries removed (all origins). payments and waiting are counts from mine, which is remaining entries for this origin. The released count is consistent: other-origin entries are always kept, so the delta is entirely from this origin's deposits past grace. ✓
Issue 1 — UX: releaseNote vanishes when the last shield is cleared
After releaseReserved() clears all deposits, setTick(t=>t+1) fires the reconcile effect. If the journal is now empty, the effect sets nativePending=false and the entire section — including the success message — disappears before the user can read it. This is not a safety problem, but on a slow device the message may be invisible.
Suggestion: render releaseNote (with a dismiss action) outside the nativePending guard, or gate the banner removal on releaseNote===''.
Issue 2 — Model gap: Verdict for deposits has no "unreadable" state
The model cannot represent a deposit whose coin verdict is unavailable. The .catch(()=>undefined) fix (the main safety-relevant change in this PR) is proven correct indirectly — Settle for a deposit past Retention releases regardless of Verdict = "nothing", so NoStrandedReservation holds without the coin answer. But the specific "unreadable coin does not block the pass" path is not exercised by any model action.
Adding a third deposit verdict "unknown" and verifying NoStrandedReservation still holds when Settle sees it would give the model direct coverage of this fix, symmetric with how BreakCoinProof already tests the complementary stranded case.
Issue 3 — README conflates model abstraction with implementation behaviour
spec/tla/README.md:515
DispatchJournaled moved out of this model: the reader's release of a deposit is allowed while its POST is still in flight
ForceRelease in the TLA model fires even when inFlight = TRUE and clock = 0 (inside the grace). The implementation does not do this — fresh(row) retains deposits within graceMs. The model is intentionally more permissive to prove safety under the worst case (the coin constraint is the real bound, not the grace window). The README is accurate but the sentence reads as if the implementation also allows this, which may confuse a future reader. A one-line note that the model is a deliberate over-approximation, and that the implementation adds the grace guard on top, would prevent misreading.
TLA spec changes — no protocol concerns
NoDoublePayment == paid <= 1 (direct landing count) is a strictly stronger statement than the previous ~falseDeath proxy. ✓
RetryLand requires ~coinSpent for deposits, enforcing the coin uniqueness bound in the model. ✓
batchAt / marked stamping restricted to noted == dead /\ ~deposit correctly reflects that deposits no longer use the batch-count mechanism. ✓
BreakCoinSpentCheck.cfg → BreakForceNotes.cfg rename is accurate; the old config was testing a guard that this PR retires. ✓
MaxBatches = 2 → 3 across all configs is necessary to cover a first attempt + retry + potential second-origin batch. ✓
Cross-repo impact
mutations.ts is internal to this repo. No external SDK (ts-sdk, go-sdk, rust-sdk, dotnet-sdk) imports it. forceRelease is additive to the return type of makeNativeMutationJournal; existing callers that destructure only the old fields are unaffected.
Test coverage
New test cases cover: boundary behaviour (at NATIVE_BOUND vs NATIVE_BOUND+1 with unknown verdict), throw-not-blocking, forceRelease on deposit/payment/fresh-shield/other-origin, two-step confirm UI, and five mutation tests that each fail on the previous code. The private-transport.test.ts boundary update correctly reflects the semantic change (verdict no longer gates release past the window).
Summary: Issue 1 (UX, not safety), Issue 2 (model coverage gap, not a runtime defect), Issue 3 (documentation clarity). The runtime logic is correct. All three items are worth addressing before merge; none is a protocol safety defect.
…esult visible
The pool operator admitted a deposit whose coin was already queued or in
flight in another slot. Admission checked spend ids and nullifiers, and a
deposit's nullifiers are fresh, so two shields of one coin both queued and
could be selected into one batch. The network refuses a batch that spends
an outpoint twice, so the batch failed, delayed everyone else in it, and
dropped the legitimate first deposit too. A misbehaving client could always
do this; the reservation release in this PR lets an honest one reach it
when a shield is released while its first copy is still queued.
submit() now refuses such a deposit as double-spend before any other check,
as the nullifier check already does, so a queued copy never answers a code
(stale-anchor, window-tag, fee-missing) that a client frees its reservation
on. double-spend is not one of those codes, so the client keeps the retry
reserved until the copy settles.
Review follow-ups:
- The release result now renders in its own dismissible notice. Inside the
unresolved-outcomes banner it unmounted with the banner as soon as the
last reservation went.
- PoolSpendJournal.tla gives a deposit an "unknown" coin verdict on any
pass, which is what reconcileJournal's catch produces, and a new
PoolSpendJournal_UnreadableCoin.cfg shows that keeping the row on that
verdict strands it.
- The README says plainly that the model's ForceRelease is an
over-approximation of the app's, which also waits out the grace, and
names the operator's coin check as outside the model.
- An operator test reused one fixture coin for two different deposits; its
plain-deposit refusal now runs before that coin is queued.
Release result vanishing. The result now renders in its own dismissible notice after the unresolved-outcomes banner, so it outlives the banner when the last reservation goes. tests/app-private-build.test.ts asserts the note is no longer inside the nativePending section.
Unreadable coin verdict.Settle now picks its verdict from Verdicts, and for a deposit that set always includes "unknown": any pass may fail to read the coin, which is what reconcileJournal's .catch(()=>undefined) produces. Past Retention an unknown deposit verdict releases like "nothing". The new PoolSpendJournal_UnreadableCoin.cfg (BreakUnreadableCoin, which keeps the row on "unknown") violates NoStrandedReservation, so the model now covers the fix directly. The base stays green at 27,307 states (6,388 distinct, every action fired), and node tools/check-native-model.mjs matches 127 configurations.
README. It now says that ForceRelease frees a deposit at any age, POST in flight included, as a deliberate over-approximation. forceRelease in the app also waits out the grace. Staying green without that wait is what shows the coin, not the grace, bounds a retry. It also says why DispatchJournaled cannot be an invariant of this model. The mermaid edge and the .tla comment carry the same distinction.
CodeRabbit raised one more point, and it changes the operator: admission did not check a deposit's coin against slots already queued or in flight. A released shield whose first copy was still queued could therefore get a second slot on the same outpoint, and a batch carrying both is refused by the network. submit in src/rollup/epoch-operator.ts now refuses that as double-spend, ahead of the anchor and fee checks. A queued copy therefore never answers a code the clients release on. A new operator test fails without the guard. The model does not cover this: paid counts landings, and two slots on one coin cannot both land. The README names it as outside the model.
The previous commit refused a deposit whose coin was already queued. Admission
cannot tell who owns a coin, and outpoints are public, so anyone could queue a
slot on someone else's coin and keep the owner's real deposit refused for as
long as they kept resubmitting.
Twins on one coin are admitted again. When a batch is selected, only the
oldest selectable slot per coin goes in, so no batch spends an outpoint twice.
Signing already decides ownership: a slot whose depositor does not sign is
dropped and the batch is rebuilt, after which the owner's slot is next. A
squatter now costs the owner one rebuild per attempt, no more than an unsigned
deposit already cost the pool.
The new operator test queues a squatter ahead of the owner on one coin. It
fails on the operator before either change, where both slots share a batch and
the owner's deposit is dropped with the squatter's. The fee test goes back to
its original order, which no longer meets an admission refusal.
One revision since the last comment, in 270d840: the operator side of the coin fix moved from admission to batch selection. Admission cannot check who owns a coin, so refusing a second slot there let anyone who knows an outpoint keep its owner refused. Both slots now queue. A batch takes only the oldest selectable slot per coin, and the existing signing step drops the slot its owner does not sign. The client is unchanged: a retry is admitted, and its reservation clears when the coin lands. The README note and the forceRelease comment say the same.
Status: 4 commits since the last pass (611b825 → 270d840). All three issues I raised are fixed. No new concerns.
Prior issue closure
Issue 1 — releaseNote vanishes when last shield is cleared (app/src/RollupWallet.tsx:751–752) Fixed (270d840).
The two deleted lines had {releaseNote&&<span>…</span>} nested inside the {nativePending&&<section>…</section>} guard, so the success message disappeared the moment the journal emptied and nativePending flipped false. The two added lines lift it into its own <section> outside that guard, with a Dismiss button. assert.doesNotMatch(banner,/releaseNote&&/) in tests/app-private-build.test.ts pins this structure so it cannot regress silently.
Issue 2 — Model gap: deposit had no "unreadable" coin verdict (spec/tla/PoolSpendJournal.tla) Fixed (270d840). Verdict (single value, no "unknown" for deposits) is replaced by Verdicts (a set). For a deposit, Verdicts = {IF pool = "landed" THEN "landed" ELSE "nothing", "unknown"}, so TLC tries all three outcomes on every Settle step. dead for a deposit now includes verdict = "unknown" /\ ~BreakUnreadableCoin, meaning an unreadable coin does not block the settle pass that ages the entry out. PoolSpendJournal_UnreadableCoin.cfg runs TLC with BreakUnreadableCoin = TRUE and expects NoStrandedReservation to be violated — the negative-case break config that proves the guard is load-bearing. The specific .catch(()=>undefined) path is now directly exercised by the model.
Issue 3 — README conflated model abstraction with implementation behaviour (spec/tla/README.md) Fixed (270d840).
The state-diagram entry now reads "at any age in the model, past the grace in the app", and the forceRelease JSDoc in src/native/mutations.ts was updated from "at any age" to "once past their grace". Both match reality.
Incremental additions
epoch-operator.ts — one slot per coin per batch selection
Set.add() returns the Set (truthy), so !!held.add(outpoint) is always true; the expression short-circuits correctly and the dedup is sound. When a squatter's spend is dropped during signing, the coin owner's spend remains in pending[kind] for the next tick — confirmed by the new test (op.pendingIds() = [own.id] after the drop) and by the final Transaction.fromPSBT check that the coin appears exactly once in the landed batch. The README note that this rule is outside the TLA model but that two slots on one coin cannot both land (the network refuses a double-spend and signing drops the slot the owner did not sign) closes the argument correctly.
PoolSpendJournal.tla — \E verdict \in Verdicts in Settle
For note spends Verdicts is still a singleton, so the change is a no-op for that branch. For deposits, TLC will non-deterministically pick any element of the two-element set on each Settle step. The safety argument holds for all three deposit verdicts past Retention when BreakUnreadableCoin = FALSE (landed → release=TRUE; nothing → dead=TRUE → release=TRUE; unknown → dead=TRUE → release=TRUE). The NoStrandedReservation invariant is maintained.
Config files — mechanical BreakUnreadableCoin = FALSE additions to all existing configs; no other semantic change.
No new findings. The runtime logic is correct, the model directly exercises the fix, and the tests cover the new paths including the negative cases.

Reported from an Android phone on Build 187: the "Some payments have unresolved outcomes" warning stayed for hours, the 50,000 sats stayed unshielded, and the user asked for a way to force-clear the reservation.
Why #167 did not clear it. A shield's journal entry released only when
settledDepositanswered that its coin was unspent.landedDepositanswersundefinedwhen the indexer read fails, the outpoint does not come back as exactly one coin, the coin is swept or unrolled, or it was spent by anything but a batch the account knows, so one of those kept the entry forever, and the reserved coin also blocks auto-shield (planFor) and renewal. Separately, a coin read that threw (rather than answeringundefined) rejected thePromise.allinreconcileJournal, so the settle pass never ran at all.Automatic release. A shield spends one coin of the wallet's, and a coin can be spent only once, so past the pool's retention plus grace the shield has either landed (coin spent, nothing to re-shield) or never can. A shield entry now releases once past that bound whatever its coin answers, and still drops early when the coin shows it landed. A coin read that fails no longer stops the pass. Payment (note-spend) entries keep their rules, including the batch-count proof.
Manual release. The warning gains "Release reserved shields" behind a confirmation. It releases shield entries older than the grace (15 minutes), at any age past that, and never a payment: a payment released by hand could skip the settle rule's proof that the pool count moved, the guard against a stalled operator view, and a retry on other notes could pay its recipient twice. A payment stays reserved until the automatic rule, which runs every minute, can prove the pool will not include it. A shield younger than the grace stays reserved too, since its post may still be in flight. The result shows in its own dismissible notice, so it stays visible after the warning disappears with the last reservation.
Operator: one slot per coin. Review found that two slots on one deposit coin could share a batch: admission checked spend ids and nullifiers, and a deposit's nullifiers are fresh. A batch that spends one outpoint twice is refused by the network. A released reservation lets an honest client reach this while its first copy is still queued. Refusing the twin at admission was tried first and dropped: admission cannot tell who owns a coin, and outpoints are public, so anyone could queue a slot on a victim's coin and keep the owner refused. Instead
runinsrc/rollup/epoch-operator.tslets both slots queue and puts only the oldest selectable slot per coin into a batch. Signing already decides ownership: a slot whose depositor does not sign is dropped and the batch rebuilt, and the owner's slot goes next. This takes effect only once the pool operator is redeployed; until then the 15-minute grace keeps the in-flight case out, but not a copy still queued past it.Model.
PoolSpendJournal.tlanow counts landings, soNoDoublePaymentis the real property: a deposit may land only while its coin is unspent, a note spend has no such bound. The forced release applies to deposits only;PoolSpendJournal_ForceNotes.cfglets it touch a payment and violatesNoDoublePayment.PoolSpendJournal_CoinSpentCheck.cfgis retired (once the coin verdict no longer gates the release, that guard is dead). A false green found while writing it (freedboth assigned andUNCHANGED, silently disabling two release branches) is fixed.Settlemay also read a deposit's coin asunknownon any pass, which is whatreconcileJournal's catch produces, andPoolSpendJournal_UnreadableCoin.cfgshows that keeping the row on that verdict violatesNoStrandedReservation. The model'sForceReleaseis deliberately looser than the app's (any age, POST in flight included); the README says so and names the operator's coin check as outside the model.Validation, local, on main
e62f3c9: new and updated tests intor-mutations,private-transportandapp-private-build, each red on the previous code: an old shield whose coin verdict is unknown (read fails, swept, spent elsewhere) releases past the window and stays inside it; a coin read that throws does not stop the pass; the banner releases a shield past its grace, keeps a younger one, and never releases a payment at any age; another origin is untouched. Mutations (shield waits for its coin, retention bound dropped, unreadable coin aborts the pass, force frees a payment, force ignores the grace) each fail their test. Six affected suites pass 241 of 241;tsc --noEmitis clean;node tools/check-native-model.mjsmatches 127 configurations (base 27,307 states, 6,388 distinct, every action fired). The new operator test queues a squatter ahead of the owner on one coin. On the operator before this PR both slots share a batch and the owner's deposit is dropped with the squatter's; with the change the squatter is batched alone, dropped at signing, and the owner's deposit lands next, spending the coin once.
