What

Three related commits, previously on local main, now routed through a PR:

  1. feat(invoice) — optional correspondentBic on the bank model, rendered
    on invoices (default template + label). Enables USD-wire accounts that need
    an intermediary bank. Only renders when present.
  2. feat(email) — new invoicr-bulk-email command to email already-generated
    invoices in bulk (select by number / --month / most-recent), grouping clients
    that share a recipient into one batch email. Extracts the group-and-send
    orchestration inline in bulk.ts into a shared sendInvoiceEmails() and adds
    bounded invoice-file lookups (so SM-1 no longer matches SM-15).
  3. feat(web) — multi-select + "Email N selected" on the invoice history
    screen; refactors the batch-email API handler to reuse sendInvoiceEmails(),
    removing duplicate grouping logic. Response shape unchanged.

Testing

  • Backend: 757 passing / 6 skipped.
  • GUI: 46 passing.
  • New coverage: selection helpers, bounded file lookups, the shared emailer's
    grouping/results, the batch-email endpoint guards, and the history-view
    multi-select bulk-send.

Note

Opened before the CI workflow (#2) landed on main, so checks won't appear
until this branch is rebased onto a main that includes CI. I'll rebase after
#2 merges.

Summary by CodeRabbit

  • New Features
    • Select invoices with available PDFs in invoice history and email them together. Clear selections manually; after successful sending, the selection clears.
    • Send existing invoices from the command line by client, invoice number, or month. Preview selections, run a dry run, or send in test mode.
    • Add an optional correspondent bank BIC to bank details and invoice documents.
  • Bug Fixes
    • Invoices without PDFs cannot be selected for emailing. Failures preserve the current selection.

Add an optional correspondentBic field to the bank model and render it on
invoices (default template + label), so USD-denominated accounts that require
an intermediary bank can show it. Only renders when the account provides one,
leaving other accounts unchanged.
Add a command that emails already-generated invoices in bulk, selecting each
by number, --month, or most-recent, and grouping clients that share a recipient
into a single batch email (like invoicr-bulk --email) without regenerating.

Extract the group-and-send orchestration that was inline in bulk.ts into a
shared sendInvoiceEmails() (returning structured per-group results), and add
pure selection helpers plus bounded invoice-file lookups (so SM-1 no longer
matches SM-15). bulk.ts now reuses the shared path.
Add multi-select with a "Email N selected" action to the invoice history
screen, so several existing invoices can be sent as one grouped batch email
instead of one at a time.

Refactor the batch-email API handler to reuse the shared sendInvoiceEmails()
and bounded findHistoryEntryByPdf() lookup, removing its duplicate grouping
logic and the SM-1/SM-15 filename-match bug. Response shape is unchanged.

📝 Walkthrough

Walkthrough

The changes add shared invoice-email sending, a CLI for selecting and emailing existing invoices, and invoice selection in the history interface. The batch-email API route and existing bulk command use the shared sender. Provider bank details and generated templates now support an optional correspondent-bank BIC.

Changes

Invoice bulk emailing

Layer / File(s) Summary
Invoice selection and lookup
src/lib/bulk-email-utils.ts, src/lib/history-manager.ts, src/lib/index.ts, tests/bulk-email-utils.test.ts, tests/history-manager-lookup.test.ts
Added client and invoice parsing, month normalization, invoice selection, and PDF/XML attachment and history-entry lookup. Tests cover selection results, filename matching, and lookup fallbacks.
Shared invoice email sending
src/lib/invoice-emailer.ts, src/lib/index.ts, tests/invoice-emailer.test.ts
Added shared individual and recipient-grouped sending with per-draft results and success/error counts. Tests cover grouping, no-batch mode, test mode, and failed sends.
Bulk-email CLI
src/commands/bulk-email.ts, package.json
Added a CLI to select existing invoices, preview email groups, run a dry run, and send invoices. Added the package binary and npm script.
Existing API and bulk-command integrations
src/api/routes/files.ts, src/commands/bulk.ts, src/lib/index.ts, tests/api/files.test.ts
The batch-email API route and existing bulk command use the shared sender. API tests cover invalid invoice input, missing PDFs, and missing clients.
GUI invoice selection and batch email
gui/src/components/history/InvoiceHistory.tsx, gui/src/components/history/InvoiceHistory.test.tsx
Added individual and select-all controls for invoices with PDFs, selection clearing, send-result feedback, and disabled controls for invoices without PDFs. Tests cover selection and submission behavior.

Correspondent-bank BIC

Layer / File(s) Summary
Correspondent BIC data and template output
src/types.ts, src/schemas/provider.ts, src/lib/template-generator.ts
Added an optional correspondent BIC to bank details and provider validation. Template data carries the value and adds a translated label.

Merge Risk: 🟡 Moderate · up to 82d5b

Some existing-invoice emails can contain incorrect invoice details or give misleading send results, and a mistyped dry-run option can create drafts. Resolve these issues before merging.

Inline comments:
Review comments at @src/commands/bulk-email.ts:
- Around line 37-41: Update the argument parsing around monthFlag and specs to
reject unsupported options, distinguish an absent --month from one with a
missing or empty value, and reject space-separated --month operands instead of
treating them as client specs; report the invalid option and exit with an error.

Review comments at @src/lib/bulk-email-utils.ts:
- Around line 34-36: Update normalizeMonthName to validate the input format
before calling parseMonthArg, accepting both MM-YYYY and YYYY-MM with one- or
two-digit months. Extract the month from the matched format and reject values
outside 1–12 so malformed dates cannot produce “Invalid Date” or roll into
another year.

Review comments at @src/lib/history-manager.ts:
- Around line 176-215: Update `matchesInvoice` and its call in `findByExt` so
the period-based match must end with the requested extension, while retaining
the underscore-bounded match. This prevents a longer invoice number from
matching another invoice’s filename.

Review comments at @src/lib/invoice-emailer.ts:
- Around line 35-63: Update createEmail and sendSingle to return and propagate a
boolean indicating whether draft creation succeeded, including false when
recipients are missing or AppleScript fails. In handleSingle, use that result to
set success and log draft creation only on success, so failures do not increment
emailSuccess.
- Around line 52-62: Update sendSingle to set context.currency from
invoice.currency alongside the other recorded invoice fields, so single-invoice
email drafts format historical amounts using the invoice’s recorded currency.
- Around line 120-156: Update the batch-mode flow around groupInvoicesByEmail to
detect invoices omitted from all recipient groups and record each omitted
invoice as a failed email, so the summary reports them as failures. Preserve the
existing handling of invoices included in groups.

Review comments at @src/lib/template-generator.ts:
- Line 193: Add the correspondent BIC placeholder and its label to the detailed
and minimal built-in templates, using the same conditional rendering behavior as
the default template so both are omitted when no correspondent BIC is present.

- createEmail now returns whether the draft was created, so a missing
  recipient or an AppleScript failure is recorded as a failure instead of
  a success
- batch mode records invoices whose client has no email recipient as
  failures instead of dropping them from the summary
- single-invoice drafts use the currency recorded on the invoice
- unknown --flags and --month with no value now exit with an error; a
  typo such as --dryrun previously created real drafts
- normalizeMonthName validates MM-YYYY and YYYY-MM (including
  single-digit ISO months) and rejects month 0 or 13
- an invoice number that is a dotted prefix of another (SM.-1 and
  SM.-1.-1) matched the other invoice's file through a bare "_N." substring
- the match is now "_N_" or a filename ending in "_N<ext>"
- only default.docx had the correspondent BIC block
- adds the same conditional line to detailed and minimal, with a render
  test over every built-in template

All 7 findings from the review of 82d5b71 are addressed, each on its inline thread:

  • 6f33770 fix(email): failed single drafts, skipped batch invoices, recorded currency (3 findings)
  • c082bd0 fix(bulk-email): unknown flags, --month without a value, month validation (2 findings)
  • 3a7fed6 fix(history): attachment lookup anchored to the file extension
  • edfcaf2 fix(templates): correspondent BIC in detailed and minimal

Verification: npm run build and npm test pass (41 files, 779 tests, 6 skipped). The new tests for the unknown-flag and BIC-template fixes fail against the previous code.

CodeRabbit's status on edfcaf2 reads "Review rate limited" with state success, so it has not reviewed these commits yet. Requesting a full review, since the rate limit can drop commits from the incremental cursor.
