Supports exact sub-dust bitcoin and asset payments through Taxi, with verified repayment terms, automatic free claims, signed-send recovery and activity receipts. The wallet owns its RFQ/carrier orchestration; generic claim/send helpers remain in the optional @arkade-taxi/client/wallet entry, and the caller-side fill planner lives in @arkade-os/swap.

  • Offer compatible sender-paid, receiver-recycled, purchased and sponsored carrier options. Preserve exact requested amounts, whole-dust loans, fare limits, claim funding and expiry floors. A 100-sat bitcoin payment locks beside a 330-sat loan; the receiver needs only the 230-sat difference to claim.
  • Keep free-claim draining sequential, preserve exact balances and asset-bearing change, and show carrier loans, fares, delivery state and actions in history and receipts.
  • Restore the displayed amount and selected asset when a pending Taxi payment is returned or explicitly forgotten. Match asset decimals to the recorded asset ID, clear stale Bitcoin values for asset sends, and keep Bitcoin entry and secondary units synchronized.
  • Journal signed sends before submission and reconcile lost responses or reloads. Preserve pending-payment guards and warnings when local recovery records are reset. A newly launched external-app request is explicitly denied if an older pending Taxi payment is discovered, without forgetting or resubmitting that payment; the app's own held uncertain send remains resumable.
  • Move the removed Taxi RFQ workflow and metadata parser into wallet-owned helpers. Keep strict carrier parsing, quote verification, whole-dust economics, deadline bounds and legacy plain-route negotiation fallback. Close the Nostr transport after each negotiation without letting a close failure mask its result.
  • Freeze SDK/swap e614c953 and Taxi client/covenant/protocol f445a800. The workflow builds that same Taxi source. Verify all five source commits, archive bytes, lock pins, installed resolutions, buildOfferFillPlan, callable TaxiClient.submitFill and retained wallet helpers. Each consumer bundle has its own byte pins; runtime modules agree with solver add backups to Nostr #209.
  • Integrate current wallet master while retaining its external-app intent, responsive desktop layout, small-amount, banner and recovery changes.

Validation

Current source 4efde8e7 resets a selected asset's available balance to zero when the asset disappears from either a nonempty or empty refreshed list. Continue stays disabled while unavailable; the exact asset's return restores its balance without changing the selected ID or draft amount. Two regressions fail before the fix and pass afterward. The focused send suite passes 26/26; the full suite passes all 95 files and 952 tests, with no failed, skipped or todo tests. All 950 prior test names remain, with exactly two additions. Normal production build, typecheck, lint, format, CSP and verification of all five frozen archives and installed exports pass. The fix is also applied locally to the native SDK 0.5 wallet integration.

Current-head CI and funded browser validation are pending. Previous head b2b086c9 passed all 950 unit tests in CI run 38084210220, and all six browser groups in Playwright run 38084210196, including three funded Taxi cases on both mobile and desktop. Those funded results precede the unavailable-balance fix.

Earlier regression coverage remains: returned and forgotten Bitcoin/asset payments restore recorded amounts and selections; reloaded available balances update the selected asset; an external-app request cannot inherit an older pending Taxi payment. Activity and claim tests preserve loans, fares, assets, receipts and held ambiguous submissions. No financial assertions or tracked scenario deadlines were weakened.

Compatibility and related delivery

This PR retains its tested frozen 0.4 SDK/swap source e614c953 and Taxi client/covenant/protocol source f445a800. SDK #970 is closed as superseded by native 0.5 #1057; its historical branch and proof remain available. #1057 at 99313fa7 passes all seven jobs, including 164 funded integration tests across six groups, and has current-head bot review coverage. Native packaged consumer integration and renewed funded proof are still in progress with wallet #936, Taxi #38 and solver #209.

Taxi #38's prior 0b2fef2 checkpoint passes all four CI jobs, 3,288 unit tests and 29 E2E assertions: 27 funded scenario executions plus two registration checks. Solver #209's prior ccd1ade checkpoint passes all normal CI jobs and all nine funded E2E groups. Those checkpoints do not establish renewed native 0.5 consumer proof.

Human protocol approval remains required. Regtest does not establish production deployment or live Mutinynet interoperability. Migration 18, deployment and release retain their documented cutover and separate approval.

Summary by CodeRabbit

  • New Features
    • Added Taxi delivery options for sending and receiving Bitcoin and assets, including fare selection, payment and claim flows, and transfer status tracking.
    • Added Taxi details to payment requests and transaction receipts, including delivery status, fees, carrier amounts, and related transactions.
    • Added a setting to automatically claim eligible free deliveries.
  • Improvements
    • Updated swap quotes to show direction-specific fees and clearer carrier-related availability messages.
    • Added a warning that resetting payment settings does not cancel signed payments.
    • Pending Taxi payments can be resumed, and returned payments restore send details.
  • Bug Fixes
    • Improved transaction history matching and displayed amounts for completed swaps.

Adds the wallet consumer for the agreed optional `carrier` descriptor: a
typed decoder, an optional projection on swap records and Tx rows, and
receipt/list disclosure. The original action stays the row.

- `carrierActivity.ts` parses the contract exactly: canonical bounded
  decimal sats read with BigInt, mode equations, Taxi-verified 64-hex
  txids, canonical non-blank transferId, and unknown fields refused. An
  unreadable descriptor is dropped, never repaired.
- `assetSwapResolver` folds the record's verified carrier txids into the
  SAME `swap:<id>`, so claim and recovery enrich one row.
- `activitiesToTxs` carries the parsed descriptor and the group's raw
  members oldest-first onto the already-built row. A persisted record is
  authoritative; with no record the group's locally resolved descriptor
  is used, so a standalone Taxi activity is still annotated.
- TransactionsList keeps the original label and annotates real Taxi use
  as "Taxi powered". Only `taxi` earns that badge.
- Receipt rows separate bought from borrowed sats, name the receipt
  reserve, keep the service fare its own figure, and give delivery
  states, reusing the existing rows.

Economics, balance math and existing groupIds are unchanged.

Tests: decoder contract, resolver/buildActivities -> activitiesToTxs for
funding/fill/claim/recovery with JSON round trip and malformed metadata,
list annotation, and receipt disclosure for recycle vs purchase.
Read carrier annotations only from locally persisted operation records, preserve producer txids, and mask carrier monetary receipt rows.
Raw asset magnitudes were compared to a contribution's claim without
their sign, so an asset LEAVING the wallet could satisfy the cap for a
`received` contribution and end up rendered as the swap's received
amount. The legacy line this replaced guarded exactly that, with
`asset.amount > 0` on the received fills. A raw member now offers
capacity only for the assets whose own direction matches the member's;
the rest carry no capacity and stay whole in the remainder, so a member
whose evidence points the wrong way fails closed to the raw view.

Parsing, duplicate resolution and the per-member candidate list also move
into indexActivityEvidence, built once by the resolver's prepare. resolve
ran allocateActivityEvidence across every swap record for every
transaction, quadratic in (transactions x records): at 800 records and
400 transactions that measured 1851.7ms of per-transaction re-parse,
against 3.4ms to build the index once plus 3.4ms for the whole resolve
loop. Allocation now builds its per-call swap states lazily so the shared
index is never mutated.
The wallet took @arkade-os/sdk@0.4.73 and @arkade-os/swap@0.0.19 from the
registry and could not see @arkade-taxi/client at all. The Taxi producer has
to be written against the accepted candidates, so freeze them instead.

Five source-qualified archives land in vendor/carrier, tracked, with a
manifest recording repository, exact source commit, SHA-256, byte length,
licence and build toolchain per archive:

  @arkade-os/sdk 0.4.74, @arkade-os/swap 0.0.20
    ts-sdk adc6b32958c36a7f9c39d6e30efdd945af874f84
  @arkade-taxi/{client,covenant,protocol} 0.0.0
    arkade-taxi 4109312c56744e967fe9fa235d9e0620447d2908

Both versions also exist on the registry, built from other source, so
resolution is proved by a symbol that only the candidate build carries:
SendDeadlineExceededError for the SDK, FundingOutputMismatchError for swap.
A different 0.4.74/0.0.20 build exports neither. pnpm-workspace.yaml
overrides catch every transitive resolution too — the packed Taxi client
pins the SDK at the bare registry coordinate 0.4.74 and swap at a path that
exists only in the Taxi checkout.

verify.mjs runs on built-in Node so it fits the Docker layer that precedes
pnpm install, and fails on source, identity or hash mismatch, on an override
or declaration that is not a frozen archive, on a lockfile whose integrity
is not the sha512 of the committed bytes, and on any installing CI job or
Docker layer that would install without it.

@arkade-os/sdk does not pack reproducibly — a re-pack renames four Expo
declaration chunks, though no runtime module differs — so the bundle is
frozen once and the lockfile pins these bytes.

No producer, no runtime wiring, no src behaviour change, no new environment
variable, nothing published.
.cursor/install.sh is the fourth installing path in this repository, after
the two CI jobs and the Docker dependency layer, and it was installing
unverified.

Enforced rather than decorated: verify.mjs now fails if that script installs
without running it first. Injecting the fault showed the check as first
written could not see it at all — findIndex returns -1 when the line is
absent, and -1 is less than every index.
The hook enforcement had the same blindness it was written to catch. Both
classes reported zero failing jobs while a job installed unverified:

  - a commented-out verify step passed in all three consumers, because
    nothing stripped comments before matching;
  - rewriting `pnpm install` as `pnpm i` made the install invisible to the
    workflow scan, so the job looked like it never installed.

One rule now covers the Dockerfile, the agent bootstrap and every workflow
job: the first install no verify precedes. `installsDependencies` reads any
spelling a drifting edit reaches for -- `pnpm i`, `npm ci`, bare `yarn`,
`corepack pnpm install --frozen-lockfile` -- and declines `pnpm exec
playwright install`, which installs browsers rather than dependencies.

Also: a missing manifest or vendor directory now fails with a named reason
instead of an unhandled ENOENT; job attribution starts at `jobs:` so an
`on:` trigger can no longer be read as a job; and a path that installs
nothing needs no verify, which was a spurious failure before.

The two blind spots are now gated rather than only fixed -- twelve cases in
the unit suite, and a mutation that makes the reader return true fails five
of them.
…count

Three more ways an installing path could look clean while nothing checked it.

Enumeration. workflowJobs yielded nothing for `jobs: # comment` or a
four-space heading, and no check noticed, so an unparsed workflow was
indistinguishable from one that never installs. Headings now take their
indent from the first one and a trailing comment on `jobs:` is tolerated;
beyond that, every workflow must yield at least one job and every install in
the file must be attributed to one, so a shape this parser cannot read fails
instead of passing.

Inference. Excusing `pnpm exec playwright install` in the reader made every
future exemption silent. It is now an install like any other, and the one
line that legitimately needs no verify carries the OPT_OUT marker in
playwright.yml. A list has to enumerate every way to install; a marker makes
every unmarked install suspect.

Execution. `if: false` and `echo …verify.mjs` both counted as verification.
A verify now counts only if its step is unconditional and its first token
actually runs the command. `if:` is live idiom in playwright.yml, so this
was reachable.

And `.cursor/install.sh` was read unguarded, still throwing a raw ENOENT --
the residual of the missing-manifest fix. It has the same named failure now.

Nine fault shapes injected and reverted, each failing for the stated reason;
`jobs: # comment` and the four-space file were checked to parse rather than
merely pass. Mutating the reader to always-true reddens nine of the file's
tests and to always-false another nine.
… is written

Three more ways a path could install with nothing having checked it.

Stage scope. unverifiedInstall had no notion of FROM, so a verify in the
builder vouched for every later stage. This Dockerfile is multi-stage and
the nginx stage is a fresh filesystem where the verify never ran and
vendor/carrier was never copied -- the same mistake fixed for workflows one
layer down. A Dockerfile stage is now the scan unit, every FROM must yield
one, and every install must be attributed to one. The vendor COPY ordering
is checked inside the stage that installs rather than across the file.

Marker placement. The exemption was read before the comment check and then
persisted until some later install consumed it, so a marker inside a step
name or an echo body excused a non-adjacent install. It must now be a
comment on the line immediately above, and there is no carried state at all.
Rarity was already breached -- ci.yml's job has one install, so one stray
marker retired the whole requirement -- so the total across scanned files is
pinned to EXEMPT_INSTALLS, today 1.

uses:-shaped installs. pnpm/action-setup is wired in both workflows and one
`run_install: true` away from installing before the verify step, invisibly.
That key now reads as an install; `run_install: false` does not.

Thirteen fault shapes injected and reverted, each failing for its stated
reason, all re-run after the comment trim. Mutating the reader always-true
reddens 13 of the file's 34 tests and always-false 12.
The set of scanned sources was hardcoded, and the one live indirection that
selects a member of it was not checked. `.cursor/environment.json` names the
installer it runs; repointing that value to `corepack pnpm install
--frozen-lockfile` and leaving install.sh on disk orphans the scanned script
without editing a script. Run rather than reasoned about: verify exited 0
while the agent environment installed unverified. Fault H catches deleting
that file, not orphaning it.

The binding is now part of the gate -- the `install` value must name the
bootstrap, and must not install before reaching it -- and the file itself
gets the named-failure treatment when it is missing or has no install key.
Blast radius was the agent environment only; CI and the image stayed gated.

Also:

The exemption cap becomes a ceiling rather than a quota. playwright.yml's
marker is decorative -- a verify already precedes it -- so `===` turned the
gate red when someone deleted a comment that did nothing. A cap should
punish excess exemptions, not mandate a useless one.

The gate into the Dockerfile COPY-ordering check omitted the `!isComment`
filter its own index applies, so a stage whose only install sat in a comment
gated in and then failed against an index of -1. Reproduced against the old
predicate before fixing.

And reported line numbers are file-relative rather than unit-relative:
units are contiguous and ordered, so a cursor recovers the offset. The nginx
stage now reports line 42 rather than line 2.

Seven new fault shapes injected and reverted; the twelve from earlier rounds
re-run and still discriminating.
The binding proved the command names the bootstrap. It did not prove the
bootstrap runs, nor that nothing installs after it. Reproduced against the
shipped predicate, all three green:

  bash .cursor/install.sh || pnpm install
  bash .cursor/install.sh; pnpm install
  echo .cursor/install.sh && pnpm install --frozen-lockfile

The first two bite rather than being theoretical: install.sh is
`set -eo pipefail` with the verify at :16, so `||` and `;` install
unverified precisely when verification failed -- the edit someone makes to
stop a flaky bootstrap blocking their agent environment.

Scanning `command.replaceAll(BOOTSTRAP, '')` rather than
`command.split(BOOTSTRAP)[0]` makes the scan unit the whole command. All
three now fail with `installs outside .cursor/install.sh`; the real command
and the already-caught `&&` prefix form are unchanged.

The success line now names the bootstrap binding among what it checked. A
message that under-reports what it verified is a mild version of every
finding in this sequence.
…gree

The wallet pinned 0.2.5 while the candidate @arkade-os/swap pulled 0.2.7, and
the two disagree about which cards are valid: 0.2.7 allows `solver_fee` and
`charges_delivered_carrier`, 0.2.5 rejects both as unknown properties. The
card store and the Solvers screen validate with the wallet's own copy, so a
solver advertising either field had its card dropped on read and on write --
it vanished from the user's list while the swap package the same wallet ships
considered it perfectly valid.

0.2.7 also prices differently where those fields appear: `solver_fee.flat`
comes off the deposit before the spread rather than off the payout after it,
`solver_fee` supersedes `fee_flat` rather than summing with it, the spread
applied is the traded direction's while `fee_bps` stays the widest one for the
fee row, and a market declaring `charges_delivered_carrier` refuses to price
without `carrierSats` instead of silently under-depositing an offer the solver
would then reject once it is funded on chain.

None of that moves a card in play today: no market in any live registry index
declares either field, and for a card carrying neither, every 0.2.7 path
reduces to the 0.2.5 arithmetic. The tests pin both halves -- the behaviour
that changed, and the control that must not.
A card carrying solver_fee prices each direction separately, and 0.2.7's
validator forces fee_bps to be the WIDEST of those spreads
(validate.js:222-238: "fee_bps must equal the widest solver_fee spread"),
so a reader predating the field can never under-deposit. But planOffer does
not price from fee_bps -- offer.js:48-51 reads solver_fee[give].bps and falls
back to fee_bps only when that side names none. The composer read the headline
number to describe a payout it had not priced.

Because fee_bps is pinned to the maximum, the error only ever runs one way:
every site over-states. On a card charging 10 bps giving base against a
headline 30, the Fees row grosses the net payout up by 0.003/0.997 where the
truth is 0.001/0.999 -- 3.006x the real fee. Measured, not estimated: a 9.99
USD payout itemised a 0.03 USD fee instead of 0.01.

Four figures came off two expressions, and one of them was written down:

  - Fees row and the give-side fiat label share buildQuoteFromPlan's
    feeFraction. The give side read EUR 10.02 for a deposit worth EUR 10.00.
  - The Minimum and Maximum hints share formatLimitMessage's. The Minimum
    erred safe; the Maximum suggested 5,015,045 sats where the market fills
    5,005,005 -- the one site whose error could cost a user an action.
  - buildQuoteSnapshot PERSISTED the widest bps into the receipt, where
    swapDisplay re-renders it as the Swap-fees row and grosses the Rate row
    back up. That number outlives the screen that produced it, which is the
    durable half of the bug.
  - Both provider backfills (the discovery pass and the restore scan's
    prepareNew) had the orientation in hand -- findMarket returns
    { market, give } -- and read ?.market?.fee_bps, discarding it.

marketFeeBps/planFeeBps mirror the dependency's private solverFeeBps over
public typed fields, so the pin and 0.2.7's behaviour are untouched.

Separately, a charges_delivered_carrier market was refused with a bare "Quote
unavailable". The refusal is correct -- nothing here quotes a carrier, and
under-depositing gets the offer refused after it is funded on chain -- but
useOfferQuote already carried the reason and the screen destructured every
field but error. It now names the charge. The refusal itself is unchanged.

Latent today: no live registry card advertises a per-direction solver_fee.

Tests pin each site independently, and all but the fallback and refusal cases
turn red again if the widest-spread pin is reintroduced.
The vi.mock for @arkade-os/solver-discovery overrode validateCard to
always return ok:true, so Solvers.tsx's real rejection branch
(`if (!result.ok) throw ...` -> "invalid card: ...") could never fire in
this suite. The two existing card fixtures (empty markets, and one also
missing version) were themselves invalid under the real validator, but
passed anyway because the mock waved them through - a positive test that
happened to hold decorative invalid data.

The `...actual` spread meant validateCard was the only override doing
anything; two sibling .tsx tests (assetSwaps, swap) already import the
same package unmocked under the same jsdom env, so nothing else needed
mocking. Removed the mock entirely, gave the two positive tests genuine
valid cards (mirroring solverCards.test.ts's legacy corridor fixture),
and added a new test that drives the old invalid fixture through the UI
and asserts the real validator's rejection message.

Confirmed red before the fix (card was silently saved instead of
rejected) and confirmed the new test goes red again if the always-ok
override is reinstated.
The installing-path scan proved a verify command was present and ordered. It
never asked whether that verify's failure would stop anything, so all of these
were reported clean: a step carrying `continue-on-error: true`, a
`RUN ... verify.mjs || true`, the same swallowed by `;`, `| tee` or a trailing
`&`, and an install chained ahead of the verify on one line. Separately, the
one-line `- if: false` never matched the anchored `^\s*if:` that `guardedLines`
tested for, because the hyphen sits in the way, so a disabled verify counted as
a real one.

Latent, not live. All four installing paths -- the Dockerfile builder stage,
.cursor/install.sh, ci.yml and playwright.yml -- invoke the verify as a bare
unconditional command, and no `continue-on-error` is written anywhere in the
tree. But a guard that cannot fail for a reachable input is the exact shape
this check exists to refuse, so it is closed rather than noted.

A verify now counts only where its status reaches the unit: any shell operator
left after `&&` is read as swallowing it, a chain is judged by its leading
command, and `continue-on-error` joins `if:` as a guard in both the dash-line
and own-line spellings.

`continue-on-error` at JOB level makes every step in that job non-fatal, and
which level it is is decided by indent against the dash opening the block,
not by whether any dash has been seen yet. playwright.yml's
`strategy.matrix.include:` puts list items above `steps:`, so a first-block
rule reads a job-level key written below the matrix as some step's own and
lets the verify keep counting. The guard covers the unit from line 0, since
YAML allows that key after `steps:` as readily as before it.

Battery: 35 faults injected into the real scanned files and run through the
shipped verify.mjs -- 6 presence, 3 order, 9 content, 5 scope, 12 consequence.
35/35 caught after the fix; 23/35 before it, missing exactly the 12
consequence faults. Clean tree exits 0 on both sides and every mutated file
was restored byte-identically.
The previous round taught the scan that a verify counts only where its failure
is fatal, and tested that on single physical lines. `swallowsStatus` reads a
physical line; a shell command is a LOGICAL one. So the `|| true` it had just
learned to refuse was re-admitted by pressing Enter:

    RUN node scripts/carrier-artifacts/verify.mjs \
        || true

Docker joins the backslash and a YAML folded scalar folds newlines to spaces,
so the command that runs is byte-for-byte the one the check exists to reject.
Unlike the nine before it this idiom is already house style rather than a
hypothetical edit -- 11 backslash continuations in the Dockerfile and 8
block or folded scalars across the three workflows, in every file that holds
a verify.

That is this file's own diagnosis one level lower for the third time: `if:`
must follow whitespace, then a `-` means a step, now a line means a command.
So the unit is derived rather than assumed. `logicalLines` folds backslash
continuations and folded scalars before anything reads them, and
`unverifiedInstall` walks logical lines while the guard set stays physical,
a verify counting only when no line of its span is guarded.

Four more routes hide in that same multi-line body and are modelled together
rather than one per round: `set +e`, an ERR trap and a BuildKit heredoc `RUN`
each stop a verify counting until the next step or RUN opens an unrelaxed
shell; and a step's `shell:` is accepted only as bare `bash` or `sh`, since
`bash {0}` drops the `-e` Actions adds and only the last command's status then
survives. A job-level `defaults:` spreads an unproven shell across the job,
and `verify.mjs` refuses a workflow-level one outright -- that block sits
outside `jobs:`, where no per-job scan can reach it.

The ordering rule went the other way. Banning every `;` and every `&&` prefix
turned `RUN cd /app && node verify.mjs` and `RUN set -e; node verify.mjs` red
though both keep the verify fatal, and `cd X && ...` is the commonest
Dockerfile idiom there is. Only an INSTALLING prefix disqualifies now, and `;`
is modelled rather than banned: the last group's status is the one that
survives.

`EXEMPT_INSTALLS` drops to 0 and playwright.yml's marker goes with it. The
narrow claim last round -- one written, one allowed, no spare -- was true and
beside the point: that marker is decorative. Deleting it leaves verify.mjs at
exit 0, because the verify at :53 already precedes both installs. A ceiling of
one exemption that buys nothing is a bypass waiting to be moved onto an
install that would otherwise be refused.

Battery: 46 faults injected into the real scanned files and run through the
shipped verify.mjs -- 6 presence, 3 order, 9 content, 5 scope, 12 single-line
consequence, 11 logical-line consequence. Caught AND attributed to the check
that fired: 23/46 at 3a70a24, 35/46 at f19e167, 46/46 here. Scoring on the
exit code alone let a fault that reddened the tree for an unrelated reason
pass as a catch, which is the cannot-fail shape in the instrument itself.
…isarms

`RELAXES_SHELL` matched `set +e` but not `set +eo pipefail`, `+ex`, `+eu` or
`+xe`, because the `\b` after the `e` demanded a lone option. `.cursor/install.sh:3`
already writes `set -eo pipefail`. Flipping that one hyphen to a plus was MISSED
end-to-end: the bootstrap verify at :16 became non-fatal, the install at :20 ran,
and the gate exited 0. Bash takes its short options combined, so the class is
every spelling carrying an `e`, plus `shopt -u inherit_errexit` alongside it.

The other half is a polarity mistake I introduced last round. Asking whether an
`&&` prefix INSTALLED made `installsDependencies` load-bearing as a NEGATIVE
gate, so every miss that heuristic already had turned from a false red into a
false green -- `RUN sh -c "pnpm install" && node ...verify.mjs` was caught at
f19e167 and missed at 0b23689, as were `make deps`, `pnpm fetch` and a sourced
script. A prefix now has to be provably harmless instead: `cd`, `set`, `export`,
`mkdir`, `umask`, `corepack enable|prepare`. That is the same polarity the shell
check next door already uses, and it keeps the false red it bought back --
`RUN cd /app && node ...verify.mjs` still counts. Sourcing is deliberately NOT
on the list: a sourced script's contents are the definition of what this scan
cannot see.

A command also does not always run where it is written. A verify alone on a line
inside an `if` condition, a function body its caller invokes as `gate || true`,
or a branch that never executes was counted in all three cases. Rather than sort
the block kinds that propagate a failure from the ones that do not, no verify
written inside a block counts at all. That takes a false red on a loop body,
which is the trade: a rule about which block is safe is the same positional
cleverness that produced the last three rounds of findings.

Also here:

- flow style defeated both `defaults` checks. `defaults: {run: {shell: pwsh}}`
  read clean at job and workflow level. The shell value is now read to a comma
  or a brace, so flow and block spell the same thing.
- `FOLDED_SCALAR` took `>-2` but not `>2-`, which YAML allows equally, so a
  folded scalar carrying `|| true` escaped through the indicator order.
- the workflow-level shell refusal reddened workflows that install nothing. It
  is scoped to workflows that install, and the battery carries a control that
  fails if an install-free `shell: pwsh` workflow ever reddens the repo again.
- the two symbols added last round are namespace-imported in the test, so
  `git checkout 0b23689 -- scripts/carrier-artifacts/lib.mjs` reproduces the
  behavioural RED (17 failed, 85 passed) instead of failing at link time. A RED
  nobody else can re-obtain is not evidence.

Battery: 59 faults plus one must-stay-green control, injected into the real
scanned files and run through the shipped verify.mjs -- 6 presence, 3 order,
9 content, 5 scope, 12 single-line consequence, 11 logical-line consequence,
13 spelling-and-construct consequence. Caught AND attributed to the check that
fired: 45/59 at 0b23689 with exactly the 13 new ones missed and the control
falsely red, 59/59 here with the control green.
Round 3 closed the shell-block class by refusing it rather than modelling it,
which was right, but refused it by ENUMERATING the openers it knew. So `{` and
`(` were missed: both `{` / verify / `} || true` and the subshell form reported
clean in the real `.cursor/install.sh`. Enumeration is how a class gets refused
incompletely, and adding two more alternatives would only move the edge.

So soundness now rests on the TERMINATORS instead. The shell grammar closes
that set at five -- `fi`, `done`, `esac`, `}`, `)` -- where the opener set is
open-ended. A terminator reached with nothing open proves a block this file
failed to name, and guards the whole shell back to its start. The opener list
survives only as precision, to keep a matched block from guarding more than it
must. A `select ... done`, named in no list here, is now caught by that rule
alone, and is in the battery to keep it honest.

Also:

- `shopt -o -u errexit`, `-ou` and `-u -o` were missed. `shopt -o` addresses the
  same options `set -o` does, so these genuinely disarm errexit; only the flag
  spelling was missing, the same shape as the `set +eo` case last round.
- a benign prefix could still carry a command substitution: `export X=$(pnpm
  install) &&` and `cd $(pnpm install) &&` counted. A substitution puts an
  unread command back inside an allowlisted one, so it disqualifies.
- `shell:` was matched anywhere on a line, so a `run:` that merely printed the
  word declared one. It is read in key position now, which keeps the flow-style
  spelling working.
- `guardedLines` gains a short block naming what is NOT modelled -- a `$( )` in
  a prefix, `set -e` re-arming, an unnamed opener, `shell: bash {0}` on a
  single-line `run:` -- and that every one of them lands on the RED side. The
  file explained the rules it has; a maintainer had nowhere to read the ones it
  leaves out, which is how the last four rounds each started.

Battery: 64 faults plus a must-stay-green control, injected into the real
scanned files and run through the shipped verify.mjs -- 6 presence, 3 order,
9 content, 5 scope, and 41 consequence across four rounds. Caught AND attributed
to the check that fired: 59/64 at 779b255 with exactly the 5 new ones missed,
64/64 here. Reverting lib.mjs alone still reproduces the behavioural RED,
9 failed of 113.
Two findings, one mechanism. A verify written inside a heredoc body counted
although it never executes -- it is text the shell writes out -- and an
unmatched `}` inside heredoc data fired the retroactive block guard, which in
`.cursor/install.sh` reaches the whole file because a shell script has no
`- ` or `RUN` line to reset on. So a verify at :16 plus a `}`-initial line at
:22 reported the install at :20 unverified.

Both are the precise limit of the inversion the previous commit made. That one
moved soundness onto the TERMINATORS because the grammar closes that set at
five. A heredoc delimiter is the USER's word, so a heredoc body is the one
nesting no closed terminator set can see. Skipping those bodies closes the
false green and the false red together, and nothing else needed patching.

The asymmetry is deliberate and is the blind spot this could have introduced.
A heredoc fed to a shell -- `sh <<EOF` / `pnpm install` / `EOF` -- really does
install. So the body is GUARDED rather than removed: `guarded` only stops a
verify counting, while `installsDependencies` still reads every line. That
install is red before this commit and red after it, and is now a battery fault
so it stays that way.

The `what this does not model` block gains the heredoc, stated as what it is
rather than appended to the safe-direction list: the delimiter is read from the
user's text, so a delimiter this misreads ends the body early and reads data
back as commands. It is the only gap in this file that lands on the GREEN side;
every other one lands RED.

On monotonicity, since the previous commit's note was right in conclusion and
wrong in reasoning: `CLOSES_BLOCK` was LOOSENED there, so round 4 could remove
guarded indices, not only add them. What rescues it is not "only ever adds" --
it is that a premature close at depth 0 triggers the retroactive add over the
whole shell, so the loosening cannot open a green path without immediately
closing a wider one. This commit adds indices only.

Battery: 67 faults and 2 must-stay-green controls, injected into the real
scanned files and run through the shipped verify.mjs -- 6 presence, 3 order,
9 content, 5 scope, 44 consequence across five rounds. Caught AND attributed:
64/67 at a790923 with the two heredoc-data faults missed and the heredoc-JSON
control falsely red, 67/67 here with both controls green. Reverting lib.mjs
alone still reproduces the behavioural RED, 4 failed of 120.
The tracked @arkade-taxi/* archives were packed from 4109312c, which predates
the provisioning work, and carried two defects into this repository.

The packed client declared '@arkade-os/swap' as
file:../../.reference/vendor/arkade-os-swap-0.0.20.tgz -- a path that exists
only in the Taxi checkout and in neither consumer. Nothing broke because the
override in pnpm-workspace.yaml replaces that resolution outright, so the
dangling spec was masked rather than absent. Taxi fixed it at the source in
packages/client and packages/app, which also unbreaks `pnpm publish -r` there,
since neither package is private. The overrides comment said the swap pin was a
path into the Taxi checkout; it is a bare registry coordinate now, like the sdk
pin beside it, so the comment says that instead.

The client also shipped dist/joint/solverFill.{js,d.ts}. That module has no
source at 4109312c or at 88ca652: it was added on eaac8db, which lives only on
feat/taxi-solver-adapter and is an ancestor of neither. Taxi builds with a bare
`tsc -p tsconfig.json` and no clean step, so output from a previously
checked-out branch survived in dist/ and `files: ["dist"]` packed it. The
filename label pins a commit and nothing else, so one unpinned module was enough
to leave every file in the archive unpinned -- verify.mjs pins bytes, not
provenance. These archives were packed from a cleared dist/, so the client is
now 18 sources to 18 modules, one to one, with no orphan.

Nothing else in this client moves. Across 4109312c..88ca652 the only tracked
change under the three packed packages is the one line in
packages/client/package.json, and every remaining module in the new archive is
byte-identical to the one it replaces -- the orphan is the whole delta. The
sponsored-fare acceptance change that the solver picks up in the same repack
landed at 62424e2, which 4109312c already contained.

Packed once and copied to both consumers, so the two now carry the same bytes:

  48e8f25f63f14609...  arkade-taxi-client-0.0.0-88ca652a.tgz
  6d3f227375cc4280...  arkade-taxi-covenant-0.0.0-88ca652a.tgz
  7328ed76d853b188...  arkade-taxi-protocol-0.0.0-88ca652a.tgz

Covenant and protocol reproduce the digests they already had: neither has a
source change across the span and their dist was already clean. @arkade-os/sdk
and @arkade-os/swap stay frozen at adc6b329 and were not repacked -- packing is
not byte-reproducible for the SDK, so moving them would be a re-freeze this
change has no reason to make.

Gates, all green and unchanged against baseline: tsc --noEmit, lint,
format:check, build, scripts/carrier-artifacts/verify.mjs, and test:unit
--maxWorkers=2 at 98 files / 1096 passed and 1 skipped, with the
carrierArtifacts battery green at 120 of 120.

Merge Risk: ⚪ Minimal · up to 4efde

The previously identified activity-grouping and recycle-description risks do not remain at this head. No actionable merge-blocking issue was established in the reviewed changes.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to ea6a0

The new payment flows include meaningful safeguards around approval, trusted keys, coin availability, and interrupted sends. However, resetting or changing servers deletes recovery information without cancelling signed payments, leaving a disclosed duplicate-payment risk after restoration. Verification inside the new payment dependencies was not fully established.

Retained concerns

  • Medium · reliability · observed: User-initiated reset, including the reset performed during server changes, removes the signed-payment journal and its duplicate-prevention gate without cancelling the remote payment. Restoring and initiating another payment can therefore pay twice. This is a disclosed lifecycle limitation, not an established attacker-triggered reset or signing bypass.
Security review details

Security Blast Radius

  • inferred — The demonstrated exposure concerns wallet bitcoin and assets, selected funding inputs, and local payment-recovery state. The inspected flows do not establish a broader tenant, deployment, infrastructure-identity, or secret-authority exposure.

Trust Boundaries and Controls

  • observed — Receiver-named Taxi endpoints reach external clients, but direct sending checks configured server and co-signer keys, optional operator pins, and carrier limits. The client checks that the receiver address is canonical and matches the trusted network and server before requesting and verifying a quote. Full downstream transaction-proof enforcement remains partially inspected.
  • observed — Incoming claim feeds are screened for the wallet receiver and remembered operator, then passed to incoming-claim verification with wallet-controlled server and co-signer trust. Withdrawals during verification prevent publication of the offer. These call-site controls do not alone prove the delegated cryptographic verification.

Resilience and Maintainability Implications

  • observed — Normal direct-send recovery preserves payment identity: stored records are keyed by network and sender, new sends refuse an existing pending record, and reconciliation checks transfer and expected outpoint. Forgetting a reported submission failure first retries reconciliation. These controls are counterevidence against routine duplicate-payment creation, but do not survive journal deletion by reset.
  • observed — The claim queue checks authorization after asynchronous inventory reads and guards identity operations against withdrawal, locking, disposal, and automatic-claim disablement. It suppresses repeated successful offers and tracks consumed funding coins within the queue. Cross-reload reconciliation of an ambiguous claim was not fully traced.

Hardening Proposals

  • proposed — Consider an exportable pending-payment recovery record or reset coordination with active payment locks, while preserving the explicit warning that deleting local state cannot revoke signed payments.

2 new commits (264d3da, 9d12ca3), 10 non-generated files changed. All 5 prior issues confirmed fixed. 0 new blocking issues.


Loop closure on all prior findings

🔴 #1 — Double-row emission when evidence is invalid — Fixed

activityHistory.ts was fully refactored. The swapAllocation?.status condition is gone entirely. The new activitiesToTxs wrapper (lines 525–539) catches tagged UnrenderableSwap errors, logs them with consoleError, removes that swap from the projection, and retries — so a swap whose row can't be built falls back to ordinary transaction rows at full value rather than either vanishing or doubling. renderedAssetSwaps is added unconditionally at line 477 before the loop continues, so the orphan sweep can't re-emit.

🔴 #2 — Silent catch {} — Fixed

The bare catch {} around buildAssetSwapActivityTx is gone. Error handling now lives in activitiesToTxs: only UnrenderableSwap is caught (anything else re-throws), and every caught error is logged with the swap id before the projection retries without that record. The surviving catch {} at activityHistory.ts:426–431 guards BigInt() parsing of swap amounts — a correct and narrow use.

🟡 #3 — WalletAssetSwap.carrier typed as parsed — Fixed

swapRepository.ts:66 now declares carrier?: unknown. The companion field activityEvidence is also unknown. The author notes an expectTypeOf assertion holds both at unknown, and the one site that was re-asserting the carved type has been corrected.

🟡 #4 — Post-install export check never runs in CI — Fixed

ci.yml:49–50 and playwright.yml:60–61 both now run node scripts/carrier-artifacts/verify.mjs --installed after their last install step. The Dockerfile exclusion stands deliberately (CI installs from the same lockfile and the pre-install verify already proves it is pinned to the frozen bytes). Accepted.

🟡 #5 — isPresent swallows ENOTDIR — Fixed

lib.mjs:113–121 now walks the path a level at a time and returns false only for ENOENT, rethrowing everything else. The cross-platform note (Windows reports ENOENT beneath a file where Linux reports ENOTDIR) is addressed by the level-at-a-time walk rather than by checking the code at depth.


Incremental diff — new findings

✅ withRfqTransport transport lifecycle fix — clean

src/lib/nostrRfq.ts:88–90 — the finally { await transport.close().catch(() => {}) } block is correct. nostrRfqTransport() runs synchronously and outside the try (line 79), so transport is always bound when finally executes. The .catch(() => {}) is deliberate — the docstring explains it and the test at withRfqTransport.test.ts ("does not let a failing close mask the negotiation result") pins the behaviour. The two new test cases cover:

  • close called exactly twice across one success and one failure negotiation, and
  • a throwing close not masking a successful result.

Both are the right regression checks for this change.

✅ Taxi vendor bump to 11f95491 — consistent

All four Taxi archives are updated atomically: package.json, pnpm-workspace.yaml, lib.mjs (TAXI_COMMIT), playwright.yml CI ref, and manifest.json all name the same commit 11f954914573dec8aa34a60182f4648aee4d448b. The client archive gets a new sha256 and byte count (8b099820… / 96042 B); covenant and protocol sha256/size are unchanged, which is consistent with only the client package having changed between the two commits. The lockfile pin and manifest integrity chain remain intact.


Summary

All five findings from prior passes are fixed. The two new commits are a correct transport-lifecycle bug fix (well-tested, no side effects) and an atomic vendor bump. No new blocking issues.

Loop closure on prior findings

🔴 #1 — Double-row emission when invalid evidence — Fixed

activityHistory.ts: the old swapAllocation?.status guard and the try { ... } catch {} block are replaced by swapRow() (wraps the row builder and re-throws as UnrenderableSwap) + the activitiesToTxs retry loop. renderedAssetSwaps.add(swap.id) is called immediately after assetSwapTx() with no intervening catch, so the orphan sweep cannot re-emit a swap whose row built successfully. Kukks's explanation (c14ffcc) is borne out: the fix is different from what was suggested and more correct — unrenderable swaps leave the projection entirely so their transactions surface at full value.

🔴 #2 — Silent catch {} — Fixed

Same fix as #1. swapRow() re-throws as UnrenderableSwap; activitiesToTxs catches it, logs via consoleError, marks the swap id in unrenderable, and retries projectActivities without it. Each id is dropped at most once. No silent drop, no orphan pending row, no missing rows.

🟡 #3 — WalletAssetSwap.carrier typed as parsed — Fixed

swapRepository.ts at head: carrier?: unknown. The activityEvidence field is gone from the type entirely. Confirmed at f6d338217c.

🟡 #4 — Post-install export check never runs in CI — Fixed

ci.yml lines 49-50: explicit node scripts/carrier-artifacts/verify.mjs --installed step runs after the last install. --installed mode fails if there is no install to inspect, so the step cannot pass vacuously. Playwright workflow updated to match. Dockerfile exclusion is intentional and documented (CI lockfile already verified against frozen bytes).

🟡 #5 — isPresent swallows ENOTDIR — Fixed (more thoroughly than asked)

lib.mjs isPresent now walks the path level by level with lstatSync; any error other than ENOENT is re-thrown. The layered walk also covers the Windows case (a file at an intermediate level reports ENOENT there, not ENOTDIR, so the check still fails correctly on that platform).


Incremental diff review (9d12ca3 → f6d3382)

The 82 files changed are dominated by the master-merge (BIP39 autocomplete, responsive layout, banner fix, SDK 0.4.79 bump, small-amount fix) plus two Taxi-branch commits: the RFQ workflow extraction and the merge commit itself. I focused on assetRfqWorkflow.ts, appIntent.ts, carrierRfq.ts, and the Send/Form.tsx changes.

Carrier-artifact updates (lib.mjs, pack.mjs, verify.mjs)

  • CANDIDATE_TAXI_RFQ_SYMBOL → CANDIDATE_TAXI_FILL_SYMBOL (requestTaxiArkadeSwap → TaxiClient with submitFill method check): assertCandidateExport now takes a requiredMethod param and validates typeof namespace[symbol]?.prototype?.[requiredMethod] === 'function'. Tighter than before — proves the callable is present, not just the class.
  • @arkade-os/swap export check narrowed to [at('package.json')] (previously also entry). Correct: swap is the wallet's direct dep; verifying it from inside @arkade-taxi/client's resolution path (entry) tested the wrong consumer. The wallet's pnpm override is what matters, and at('package.json') resolves it.
  • pack.mjs: adds @arkade-os/sdk and @arkade-os/swap to dependencies in the consumer manifest as well as overrides. Ensures pnpm sees them as direct deps of the harness, not just override targets.

appIntent.ts

Callback validation: validCallback enforces HTTPS-only (HTTP only for localhost/127.0.0.1/[::1]), rejects username/password, enforces MAX_CALLBACK_LENGTH = 2000, parses via new URL(). No string-concatenation open-redirect risk. callbackUrl builds the redirect via the URL API with explicit set/delete for each field; on error, it drops address, pubkey, status, and txid before appending error=denied. BIP21 validation requires at least one of address/arkAddress/invoice/lnUrl. Length cap on the payment request (4500 chars). This is well-hardened.

readInitialAppIntent reads the URL once, strips the params from history immediately, and stores the intent in context. The intent is effectively immutable for the session, so no stale-closure issues from the useEffect that calls leaveAppSend are exploitable.

assetRfqWorkflow.ts

Double-spend protection is explicit and correct (src/lib/assetRfqWorkflow.ts comment before fundOffer: "A funding failure may follow broadcast; retrying another route could pay twice"). The outer retry loop in payAssetRequest only continues when expired(validUntil) is true before fundOffer is called — any throw from fundOffer propagates out without a retry. The user re-confirms on every iteration (the refreshed: true flag is set for lapsed > 0). No path reaches fundOffer a second time for the same quote.

Taxi-route fallback logic: routes.splice(i + 1, 0, taxi) inserts the fresh Taxi quote at the next position; the for loop's length re-evaluation picks it up. The routes.push(undefined) for the legacy fallback is guarded by !legacy so it fires at most once per solver.

carrierRfq.ts — quote verification at the RFQ boundary

echo.physicalSats !== dust check (new RestArkProvider(arkServerUrl).getInfo()) uses the wallet's configured server, not the solver. The timing double-check (before and after requestArkadeSwap) ensures a quote that drifts past valid_until during key derivation is rejected. assertReceiverPaidEchoMatchesExpected validates the echo against the pre-checked quote snapshot before any funds move. This chain looks correct.

Send/Form.tsx — external-app / pending-Taxi guard

leaveAppSend() is invoked at two sites: in the useEffect that checks getPendingDirectTaxi on mount, and in the submit handler. Both sites check appIntent?.status === 'send' before calling leaveAppSend. resetFlow() clears React flow state; the pending Taxi record in persistent storage is untouched. The next normal (non-app-intent) open of the send form will still see the pending Taxi. Header back prop is wired to leaveAppSend rather than a bare true so the browser back button also sends error=denied to the callback.

One minor note: leaveAppSend is not memoised with useCallback, so the useEffect that closes over it captures the render-time version. Since appIntent is set once at load and never mutated, this is harmless in practice. If appIntent ever becomes mutable, this would need a useCallback dependency.


What this diff gets right

All five blocking findings are closed. The incremental work (wallet-owned RFQ orchestration, app-intent send, updated artifact pins) is coherent and the security surface (callback validation, double-spend guard, carrier quote verification) is well-handled. No new protocol-critical paths are introduced. No VTXO, signing, forfeit, round, or unilateral-exit logic is touched.

The "reset deletes pending-payment journal" reliability concern (from CodeRabbit's security summary and earlier passes) remains an acknowledged lifecycle limitation, not a new finding here.

Returned and forgotten Taxi sends now restore the displayed amount, recorded asset identity and decimals, and Bitcoin amount state. This keeps the visible request aligned with the value Continue uses.

Validation: 95 files and 948 tests pass, including four regression cases; production build, types, lint, formatting and pinned artifact verification pass.

2 commits, 3 files changed since f6d338. All 5 prior findings Fixed. 0 still open. No new issues.


Loop closure

🔴 #1 — Double-row on invalid evidence — Fixed (c14ffcc)

The orphan sweep now tracks every id it has emitted via a dedicated set before entering the raw-member loop, so the same swap cannot appear twice regardless of evidence status. The new test in activityHistory.test.ts pins the resolved-but-conflicting-evidence shape.

🔴 #2 — Silent catch {} — Fixed (7b6a338)

The projection-retry approach is strictly better than the log-and-mark I suggested: a swap whose row builder throws now leaves the projection entirely, so the allocator returns its transactions to full-value ordinary rows rather than silently zeroing them out. The tagged error goes to the log.

🟡 #3 — WalletAssetSwap.carrier typed as parsed — Fixed (bdbf7b2)

Both carrier and activityEvidence are now unknown. The fix surfaced and closed the one type-level bypass at ActivityHistoryOptions.swaps. expectTypeOf assertions hold both fields at unknown.

🟡 #4 — Post-install export check skipped in CI — Fixed (fbc2566)

ci.yml and playwright.yml now run verify.mjs --installed after their last install. --installed fails vacuously when no install is present, so the step cannot pass silently. The scanner enforces this of every installing workflow job. The Dockerfile exclusion is intentional and documented; CI installs the same lockfile.

🟡 #5 — isPresent swallows ENOTDIR — Fixed (016efcd)

Only ENOENT returns false; all other errors are rethrown. The Windows path is also closed: presence is walked level-by-level so a file in place of a directory reports as a malformed install before any descendant path is resolved. Fixtures cover both cases.


Incremental diff assessment

src/screens/Wallet/Send/Form.tsx — restoreTaxiSend

The new function replaces two call sites that previously called only setSendInfo + setRecipient, leaving the asset selector, entry mode, amount text input and valueSats stale.

The fix is correct on both paths:

Asset path (send.assets present): constructs or retrieves the asset option from assetOptions (falling back to a synthetic option from assetMetadataCache), explicitly forces entryMode to 'unit' (correct — assets have no fiat conversion), sets amountTextValue via centsToUnits(asset.amount, option.decimals), and clears valueSats. The decimal lookup prioritises the live metadata, then the option, then falls back to 8 — safe because the original send was made with the correct metadata in cache.

BTC path (send.assets absent): calls getTextValue(sats) without an explicit fiat override. getTextValue defaults to the current fiatEntry state, so a user who was in fiat mode gets the fiat representation of the restored sats — internally consistent with setValueSats(sats) holding the correct underlying value. This is the same behaviour as every other getTextValue(sats) call-site in Form.tsx (e.g., lines 393, 418, 850). The deliberate contrast with the form-init path (which passes getTextValue(sendInfo.satoshis, false) alongside setEntryMode('unit')) is acceptable: init forces unit mode; restore preserves current mode.

src/test/screens/wallet/send.test.tsx — four new test cases

The .each(['returned', 'forgotten']) parametrisation for both the BTC and asset paths gives complete coverage of the two recovery outcomes:

  • BTC: verifies input[name="send-amount"] restores to 100, secondary BTC text is present, setSendInfo called with { arkAddress: 'old-taxi-recipient', satoshis: 100 }.
  • Asset (recorded-asset, decimals: 2, assetAmount: '12345'): verifies input restores to 123.45, asset selector shows REC (not the previously selected OTHER), setSendInfo called with correct BigInt(12345n) and satoshis: 0.

Both test cases intentionally start with a different asset selected to prove stale selection is cleared. The 'forgotten' arm verifies forget() was called once; 'returned' verifies it was not called. This is the right shape for regression tests on a UI state-restoration path.

src/test/e2e/taxi/helpers.ts — mint success screen dismissal

Adds page.getByRole('button', { name: tr.mint.backToArkadeMint, exact: true }).click() before returning the minted asset id. No financial assertions changed; this is purely a test-sequencing fix preventing the E2E suite from proceeding while the mint success overlay is still mounted.


No new findings.

The incremental diff is tightly scoped to the UI state-restoration bug. No protocol paths (VTXO handling, signing, forfeit, round lifecycle, unilateral exit) are touched. The test suite grows from 944 to 948, all passing per the linked CI run.

1 commit since last pass (b2b086c). All 5 prior findings fixed. No new blocking issues.


Prior finding closure

🔴 #1 — Double-row emission when evidence is invalid — Fixed

projectActivities (the renamed inner loop) no longer gates on swapAllocation?.status. Any swap matched by swapId is rendered unconditionally and added to renderedAssetSwaps (line 477). The orphan sweep's renderedAssetSwaps.has(swap.id) guard (line 505) prevents re-emission. The intermediate swapAllocation/hasVerifiedMembership machinery is gone; double-emission through the invalid-evidence path is no longer possible.

🔴 #2 — Silent catch {} in main loop — Fixed

The try-catch around swap row building is removed. The outer activitiesToTxs (lines 525–539) uses a tagged UnrenderableSwap error: if assetSwapTx throws inside projectActivities, the outer function logs the reason, adds the swap to an unrenderable Set, and re-projects without it. Non-UnrenderableSwap errors propagate. Each id is dropped at most once. This is a cleaner fix than my suggested in-place mark-and-log.

🟡 #3 — WalletAssetSwap.carrier typed as parsed JSON — Fixed

swapRepository.ts:66 is now carrier?: unknown. Confirmed. activityEvidence carries unknown too. An expectTypeOf assertion in the test suite enforces it.

🟡 #4 — Post-install export check never runs in CI — Fixed

ci.yml now runs node scripts/carrier-artifacts/verify.mjs --installed after pnpm install. The --installed flag fails when no install is present, so the step cannot pass vacuously. Playwright CI has the same step. Docker remains without a post-install verify; @Kukks' reasoning (CI installs the same lockfile, and the pre-install verify already proves the bytes are pinned) is an acceptable trade-off deliberately taken.

🟡 #5 — isPresent swallows ENOTDIR — Fixed

lib.mjs:113–125 now walks the path one level at a time. At each level, lstatSync(path).isFile() returns true when a file is encountered where a directory should be, causing isPresent to return true → resolveInstalled throws "installed but does not resolve" → verify.mjs exits 1. The catch rethrows anything that isn't ENOENT, so errors other than genuine absence propagate. The level-by-level walk additionally handles the Windows case where lstat beneath a file reports ENOENT rather than ENOTDIR. More complete than the one-liner I suggested.


Incremental diff — b2b086c (Form.tsx +5/-4, send.test.tsx +163/-23)

Form.tsx:528–533 — functional update for asset selection after wallet reload

The old guard if (found && !selectedAsset) prevented refreshing a selected asset's balance once any selection existed. The new code:

if (assetOptions.length === 0) return
setSelectedAsset((current) => {
  const assetId = current?.assetId ?? sendInfo.assets?.[0]?.assetId
  return assetOptions.find((option) => option.assetId === assetId) ?? current
})

Key properties:

  • Precedence is right. current?.assetId takes priority over the preset so a wallet reload after a returned Taxi payment refreshes the balance of whatever is currently selected rather than resetting to the preset. The second test case pins this: re-rendering with updated metadata refreshes the user-chosen asset's ticker/balance without restoring the preset from sendInfo.assets.
  • Functional update form is correct. Avoids stale closure on selectedAsset; React bails out via Object.is(null, null) on pure-bitcoin flows, so the extra call is a no-op.
  • ?? current fallback. When the selected asset is absent from the new assetOptions, the selection is preserved. assetOptions is built from assetBalances (not availableAssetBalances), so an asset only disappears entirely if it leaves assetBalances entirely — a zero spendable balance doesn't remove it. A retained stale option would show stale balance but is rejected by the submit-time balance check. This is the pre-existing bounded send-flow issue CodeRabbit noted; this commit doesn't worsen it.
  • Dep array unchanged ([assetOptions, sendInfo.account, sendInfo.assets]). The sendInfo.assets reference is stable across pure-amount edits (spread preserves the nested array ref), so the effect fires only on meaningful state transitions.

send.test.tsx — two new regression cases both confirmed to fail on the prior code:

  1. Refreshes returned Taxi asset balance so the recorded payment can continue — mounts a stateful ReloadingForm that holds sendInfo and availableAssetBalances independently, simulates ReturnedDirectTaxi, fires reloadWallet, releases it with act, then asserts refreshed balance and enabled Continue button. Correct and sufficient regression coverage for the balance-refresh path.
  2. Refreshes metadata for the chosen asset without restoring a different preset or changing its amount — user explicitly picks 'chosen-asset'; re-render with updated metadata should refresh that selection, not restore 'preset-asset' from sendInfo.assets. Covers the primary risk that current precedence might be broken by a future sendInfo.assets change.

No issues to raise on this diff. The fix is minimal, correctly motivated, and the test coverage is thorough.

1 commit, 2 files changed since b2b086c. All 5 prior issues are now fixed. The new commit is clean.


Loop closure on prior findings

🔴 #1 — Double-row emission when evidence — Fixed

The / condition and the surrounding block are both gone. activityHistory.ts:473-479 now unconditionally renders assetSwapTx(swap, …) when an activity carries a known swap id, and the orphan sweep at L505 guards on renderedAssetSwaps.has(swap.id). The old double-emission path for invalid-evidence swaps is structurally closed.

🔴 #2 — Silent catch {} — Fixed

Same refactoring. The exception-swallowing block is removed. Direct rows.push(assetSwapTx(…)) followed immediately by renderedAssetSwaps.add(swap.id) — no suppression, no orphan re-emission path.

🟡 #3 — WalletAssetSwap.carrier typed as parsed — Fixed

swapRepository.ts:66 now reads carrier?: unknown. Confirmed at this head.

🟡 #4 — Post-install export check never runs in CI — Fixed

.github/workflows/ci.yml:43-50 now runs verify.mjs before install and verify.mjs --installed after. The post-install step uses --installed which fails when there is no install to inspect, so it cannot pass vacuously.

🟡 #5 — isPresent swallows ENOTDIR — Fixed

scripts/carrier-artifacts/lib.mjs:113-125: the function now walks the path one level at a time, catches ENOENT only (returns false), and rethrows everything else. A file where a directory is expected (Linux ENOTDIR, Windows ENOENT) surfaces as a throw through resolveInstalled → verify.mjs pushes to failures → exit 1. The broken-symlink path continues to work as intended.


Incremental diff — 4efde8e7

src/screens/Wallet/Send/Form.tsx:523-535 — asset-availability effect

The fix is correct:

  • Removes the if (assetOptions.length === 0) return guard that was preventing any update when the options list emptied.
  • When the chosen asset is not found in the refreshed list, returns { ...current, balance: BigInt(0) } rather than the stale current. The UI correctly shows "0 <ticker> available" and disables Continue.
  • Returns null (not a zero-balance phantom) when there was no prior selection.
  • When the asset re-enters the list, assetOptions.find takes the left branch and restores the live balance from the fresh option; no setSendInfo call fires while the asset is absent, so the draft amount and asset id are preserved across the gap.

The { ...current, balance: BigInt(0) } spread is safe: trusted, decimals, assetId, name, ticker, icon are intrinsic to the asset, not sourced from the balance list, so spreading them from the previous option is correct while the asset is temporarily unavailable.

src/test/screens/wallet/send.test.tsx:726-800 — new it.each case

Covers both failure modes (missing from a non-empty list, missing from an empty list), verifies the disabled state, checks the draft amount survives unchanged, confirms no setSendInfo calls during absence, and verifies the restored balance and re-enabled Continue on reappearance. Regression coverage is proportionate to the fix.


No protocol-critical paths (VTXO/signing/forfeit/round/exit) are touched by this commit. The fix is purely UI state.
