New endpoints:
POST invoices/eims/bulk-register { invoiceIds: [...] } — trigger
POST eims/webhook/bulk-register — MoR's callback
Fundamentally different shape from single register: bulkRegister
answers only {conversationId, status:202} immediately: MoR processes
the array asynchronously and pushes the real per-invoice results
(a mix of accepted/rejected in one array, per the collection's own
examples) to a webhook configured out of band. So this ships as two
halves that don't share a call stack — EimsBulkRegistrationService.
registerBulk() reserves a contiguous block of counters (durable
reservation, same doctrine as single register, extended to N items)
and submits; handleBulkCallback(), invoked by the new
EimsWebhookController whenever MoR gets around to it, settles.
New EimsSystemState.inFlightConversationId is the bulk equivalent of
inFlightInvoiceId — a whole batch outstanding, not one invoice — and
the two markers block each other since they share the same counter
sequence. The conversation id isn't known until MoR's 202 arrives, so
reservation stamps a locally-generated placeholder first (same
commit-before-the-network-call reasoning as single register), then
swaps it for MoR's real id right after — the only value the callback
can actually use to find the batch again.
Only the first invoice in a bulk batch chains via PreviousIrn — every
other item gets an empty string, matching the collection's own
two-invoice example exactly (MoR doesn't expect a batch to chain to
IRNs that don't exist yet at submission time).
Webhook has no auth (MoR has no JWT to send) — the conversation id
embedded in the payload is what stands between this and a forged
callback: an item only ever touches an invoice actually holding that
exact id, and an unknown id is logged and ignored, never applied.
Migration 3580000000000: eims_system_state.in_flight_conversation_id,
invoices.eims_bulk_conversation_id (tags which batch an invoice was
submitted in, so a stuck batch — webhook never arrived — can be found
and reconciled by conversation id). Applied to dev DB and recorded in
freight.migrations directly (idempotent IF NOT EXISTS DDL).
Not live-testable from this sandbox (no route to MoR's real gateway).
Signing the whole array as one envelope, the way single /v1/register
was confirmed live to need despite the collection's raw example
showing no envelope, is the reasonable extension of that confirmed
behavior, not a blind guess — but it has not itself been exercised
against the real gateway. Left for the first live bulk attempt to
confirm, same as every other MoR-facing assumption this integration
has made.
New endpoint: POST invoices/eims/bulk-cancel, body { items: [{invoiceId,
reasonCode, remark?}] }. Same eimsCancel permission as single cancel — a
batch-scale version of the same irreversible-at-MoR action, not a new
capability.
Same local-eligibility doctrine as single cancel: an already-cancelled or
never-registered invoice is refused right here, no HTTP call, before it
gets a seat in the batch. Only genuinely eligible invoices go into the one
/v1/bulkCancel request; every outcome (local refusal or MoR's own
per-IRN result) is reported back independently — one invoice failing
never blocks the rest.
MoR's bulk response mixes success and error shapes in the same array,
disambiguated by Status (capital, error) vs status (lowercase, success)
— matched back to our invoices by IRN. Notably the bulk success shape
carries no cancellationDate at all, unlike single cancel.
Left out of this pass: bulkRegister. It's async (returns only a
conversationId immediately, results arrive via a webhook callback we
don't have yet) and needs manual counter/previousIrn management per
the collection's own docs — a materially different reservation model
than today's single-invoice TX1/TX2 pattern. Scoping that is a
separate, bigger piece of work.
Add manual single-invoice registration, verification and reconciliation.
Nothing submits automatically; invoice creation is untouched.
Sequencing uses a durable reservation. The counter is consumed and the
holder recorded in a committed transaction before the request leaves the
process, and the HTTP call runs outside every transaction. A counter is
therefore never reused once an attempt begins, a crash mid-flight leaves the
reservation standing instead of inviting a blind resubmission, and an
ambiguous result blocks the whole system number rather than one invoice --
PreviousIrn is unknown, so any later document would chain to a stale IRN.
Deterministic rejections (400/406/401/403) mark the invoice FAILED and clear
the block. Timeouts and 5xx mark it UNKNOWN and keep it. Since /v1/verify
takes an IRN we never received in that case, POST :id/eims/resolve is the
exit: record the IRN confirmed in the MoR portal, or discard. A recorded IRN
is verified against the gateway first and refused unless EIMS reports it
against this invoice's document number.
Business and tax configuration is validated locally before anything is
locked, allocated or sent, so a missing tax code fails naming the exact
environment variables instead of at the gateway. No tax value is defaulted.
Filing gets its own permission (invoices:eims_register) rather than riding
on invoices:export -- registration is irreversible at MoR and must not
follow from the right to download a PDF.
