fix(reconcile): flag a partial ledger read instead of reporting it as complete

[erhnysr]

Problem

loadGatewayRows follows the /v1/usage cursor. When a page after the first fails, it returns the rows it already has. When the 40-page cap is reached with a cursor still pending, it does the same. Nothing marks either result as short, so reconcile treats a partial ledger as the whole window.

A partial ledger reconciles cleanly. Every charge on the unread pages drops out of chargedNotRecorded, so the output shows no unrecorded charges and clawrouter reconcile exits 0, which a scheduled check reads as nothing to report. UsagePage says "a visible gap beats a silently short page", and this is the one gap on that path that is not visible.

Reproduced with a mocked /v1/usage: page 1 holds the call this machine made, page 2 holds a $2.43 charge made elsewhere. On main, with both pages read:

  Gateway charged:  $2.44   (2 settled calls)
  Journal recorded: $0.01
  ⚠ Charged but NOT in this machine's journal: 1 call(s), $2.43
exit 2

On main, with page 2 returning 502:

  Gateway charged:  $0.01   (1 settled calls)
  Journal recorded: $0.01
  Matched:          1, of which 0 disagree on amount
exit 0

Change

• loadGatewayRows keeps the rows it read but sets incomplete to the reason: which page failed, or that the page cap was hit. A first-page failure still returns undefined, as before.
• reconcile copies it to ReconcileResult.ledgerIncomplete, and formatReconcile prints a "Partial ledger" warning above the totals it qualifies.
• New reconcileExitCode: 2 for unrecorded charges (unchanged), 1 for a partial read, 0 otherwise. cmdReconcile uses it, and the README documents the new exit code.

Days the gateway itself lists in unavailable_days keep their current exit code. Happy to treat them the same way if you prefer.

Tests

• src/reconcile.test.ts: a failed second page and the page cap both mark the read incomplete (both fail on main). The warning prints before the totals, and the exit code is covered for each case. A full read stays unmarked, and the cursor is passed back verbatim.
• npx prettier --check ., npx eslint src/, npm run typecheck, npm test (1153 passed), npm run build, the brand-numbers check and the lifecycle integration test all pass locally on Node 22.

Summary by CodeRabbit

• New Features
  • Reconciliation warns when gateway ledger data is incomplete while retaining results from successfully read pages.
  • Exit codes distinguish unrecorded charges from incomplete ledger reads; a clean, complete reconciliation exits successfully.
• Documentation
  • Clarified reconciliation exit codes and noted that pending-pricing rows are excluded from totals.

📝 Walkthrough

Walkthrough

Gateway pagination retains rows read before a later-page failure, repeated cursor, or page limit. Reconciliation reports incomplete reads, displays a warning, and selects exit codes based on ledger completeness and charges missing from the local journal.

Changes

Reconciliation

Layer / File(s)	Summary
Gateway pagination and incomplete-read result src/reconcile.ts, src/reconcile.test.ts	loadGatewayRows returns accumulated rows and an incomplete reason when a later page fails, a cursor repeats, or the page limit is reached. Tests cover pagination, failures, repeated cursors, and complete reads.
Reconciliation reporting and exit status src/reconcile.ts, src/cli.ts, src/reconcile.test.ts, README.md	Reconciliation carries the incomplete-read reason into its result and output. The CLI and documentation use exit code 2 for unrecorded charges and code 1 for an incomplete ledger when no such charges exist. A complete clean reconciliation returns code 0.

Priority: ➖ Normal

Merge Risk: ⚪ Minimal · up to 9d46d

Partial ledger reads are reported as incomplete, and a first-page read failure remains an explicit error with exit status 1. No actionable merge risk is established by the supplied review context.

- Line 130: Update loadGatewayRows to reject a pagination response whose next
cursor does not advance before appending its rows, so repeated pages cannot add
duplicate charges or be reported as page-cap exhaustion. Keep the page-cap test
in src/reconcile.test.ts using advancing cursors.
