add Group 9 delivery scenarios for self-haul and last-mile paths

Browse Source 
- Implemented G9·S38 tests for customer self-haul truck assignments, ensuring compliance with container limits and truck assignments.
- Added G9·S39 tests for last-mile delivery, self-haul, and yard pickup, verifying independent paths for multiple bookings on the same train.
- Created seed data for Group 1 and Group 2 scenarios, ensuring proper setup for weight and capacity tests.
- Updated booking interface to deprecate  in favor of  for better clarity in allocations.

**Read `SCENARIO_ENGINE_NOTES.md` before changing any of these.** Five
scenarios describe behaviour the engine does not implement (out-of-order
checkpoints, second-duty gating, hazardous/reefer clamping) or invert what it
does (mid-corridor intercity). Those are written as a passing test of CURRENT
behaviour plus an adjacent `it.skip` naming the desired behaviour — un-skipping
one is the definition of done for the corresponding fix, not a test repair.
Three specs are also flag- or policy-dependent and say so in their headers:
`g3_export` needs `FREIGHT_EXPORT_SPLIT` off, and `g4_multi_schedule` asserts
the whole-placement policy (S20) rather than the fill-first one (S21).
### Group 1 conventions (`flows/g1_*.cy.ts`)
The visual counterpart to the corridor suite — helpers in `flows/g1-utils.ts`,
arrange-data in `fixtures/seed-g1-train.sql` (run it AFTER
`seed-import-corridor.sql`).
Two things make these different from the older flow specs:
- **A 53-wagon BUILT train** (`TRN-G1-1`), not a loco pair. A loco-pair
schedule cannot hold 53: `syncScheduleMaxWagons` recomputes `max_wagons`
from locomotive length (`floor(760 / 13.966) = 54` on this corridor). A
built train's physical consist wins outright — see
`booking-batch.service.ts:4152`. The consist staff marshal IS the capacity.
- **The configuration phase and every capacity verdict run through the UI**:
the consist is seen in the Train Builder, the schedule is created through
the real "New schedule" form, the batch is run from the
`Doc review complete — run batch` button, and FULL/NOT FULL is read off the
batch board's Priority Tracking tab — which renders the literal
`Capacity line · 53/53 wagons · FULL` divider plus `In the batch` /
`Waiting list` / `Expired` lanes.
Bulk cargo still goes through the API (`bookContainers`): a 30-wagon booking
is 30-60 ISO-number inputs, which tests the form rather than the engine. Each
scenario books its ONE small booking visually via
`bookContainersVisually()`. **Payment is always API-driven** — the portal has
no mock payment path; "Pay now" redirects off-origin to a real gateway, which
Cypress cannot follow.
## Extending
Deep module flows (booking wizard → staff approval → scheduling → billing)

# Scenario ↔ engine reconciliation (S1–S40)
Verified against the API source while writing the Group 1 specs. Every claim
below carries a `file:line`; re-check them before trusting this file, it is a
snapshot of the code as of the freight_feature/usermanagement branch.
The point of this file: several scenarios in the original 40-case document
describe behaviour the engine does **not** implement. Those are not spec bugs
to code around — they are either product gaps worth a ticket, or scenarios
whose premise needs restating. Writing a green test against a premise the code
contradicts is worse than having no test.
## Capacity: 53 vs 54
The scenarios are written for a **53-wagon** train. A loco-pair schedule cannot
hold 53 on this corridor: `syncScheduleMaxWagons` recomputes `max_wagons` as
`floor(locoLength / shortest active wagon length)`, and `seed-import-corridor.sql`
deliberately pins that at `floor(760 / 13.966) = 54`.
A **built train** is exempt — `booking-batch.service.ts:4152`:
const maxWagons = physicalWagons ?? capacityLimits(loco).base.wagons;
So Group 1 runs on `TRN-G1-1`, a 53-wagon built consist (`seed-g1-train.sql`).
Note `train-capacity.util.ts:107` calls 53 "the marshalling figure" and says the
slot count is "never a fixed 53" — the number is real, it just has to come from
a consist rather than from locomotive length.
## Confirmed — scenario matches the engine
| Scenario | Engine fact | Where |
| --- | --- | --- |
| S1/S5 cascading promotion | `fillFromWaitingList` loops up to 10 rounds until a pass reserves nothing | `booking-batch.service.ts:2788` |
| S4/S6 split offers | `booking_batch_offers`, `status` defaults `OFFERED`, `offered_wagons` | `booking-batch-offer.entity.ts:27,46,73` |
| S9 heavy VGM | NW5 tare **22.4T** → 2×28 + 22.4 = 78.4T gross, exactly as the scenario computes | `train-capacity.util.ts:16,82` |
| S11 split ignores tolerance | tolerance "spendable only by admitting a booking whole, never by a split" | `train-capacity.util.ts:58`, `booking-batch.service.ts:4109` |
| S13 holds occupy space | reserved = `SELECTED_FOR_BATCH`/`AWAITING_PAYMENT`, subtracted from capacity until the deadline lapses | `bookings.repository.ts:1372`, `booking-batch.service.ts:4487` |
| S18 oversized export rejected | 409 at `requestOperation` with a sized message | `booking-transition.service.ts:1016`, `booking-batch.service.ts:900` |
| S25 per-station arrival | checkpoint at an intermediate yard auto-unloads bookings destined there | `booking-journey.service.ts:261` |
| S30 cancel snapshot | `train_schedules.wagon_allocation_snapshot` jsonb, frozen before wagons are released; holds wagon numbers + per-slot weights | `train-scheduling.service.ts:3984`, `4647` |
| S31 wagon transfer | statuses `PENDING/PARTIALLY_FULFILLED/FULFILLED/CLOSED_SHORT/CANCELLED` | `packages/types/src/freight/index.ts:353` |
| S31 movement ledger | `wagon_movements`, kind `EMPTY_REPOSITION`, carries `transfer_request_id` | `wagon-movement.entity.ts:16,49,55` |
| S37 risk history | `clearance_milestones.metadata` → `riskLevel` + append-only `riskHistory` (oldest-first) | `clearance-milestone.entity.ts:38`, `clearance-milestone.service.ts:250` |
| S38 max 2 per truck | `MAX_CONTAINERS_PER_TRUCK = 2`, error `A truck carries at most 2 containers` | `truck-load.util.ts:5,36` |
| S38 duplicate container | 409 `Container X is already loaded onto another truck` | `truck-load.util.ts:52` |
| S40 re-price parks the booking | batch pool is `status = 'PAID'` exactly, so `PRICE_CHANGED_PENDING_CONFIRM` holds zero capacity | `bookings.repository.ts:1136` |
## Corrected — same intent, different mechanism
**S7 government.** The scenario says government "jumps the queue" via an
institution field and a +50,000 priority. Two corrections:
- the bonus is real (`GOVERNMENT_PRIORITY_BONUS = 50_000`,
`rule-engine.service.ts:258`) but keys off `bookings.is_government`, set from
`contracts.is_government` — there is no institution lookup;
- government does not merely outrank, it **preempts**: it displaces the
lowest-priority already-reserved commercial booking and rides unpaid
(`preemptForGovernment`, and see `flows/government_preemption.cy.ts`).
Created via `POST /bookings` + `POST /bookings/:id/government-expedite`
against a `kind='government'` company, not through the contract wizard.
**S8 priority tiers.** `USD_PAYER` / `RAIL_AND_FORWARDING` no longer exist as
priority types — migration `1783000000000-ReplacePriorityRulesWithPriorityConfigs`
replaced `priority_rules` with `priority_configs`, whose `type` is only
`WAGON | CURRENCY | CUSTOMS`, scored by wagon-count range
(`priority-config.entity.ts`, applied at `rule-engine.service.ts:247`). The
scenario's ordering intent survives as: a CURRENCY(USD) config, a CUSTOMS
config, and a plain booking that matches neither.
**S3 "day stays open".** Best asserted through
`GET /bookings/:id/day-availability?date=` → `{ fits, freeWagons, trainsForDay }`
(`booking-transition.service.ts:1078`), which is what the portal calendar reads.
## Contradicted — the engine does NOT do this
These need a product decision before a test can be written honestly.
**S26 — mid-corridor intercity is NOT blocked.** The scenario expects
Dire Dawa → GMP (both Ethiopian) to be rejected as disabled intercity. It is
the opposite: DOMESTIC is a first-class direction derived from yard countries
(`bookings.service.ts:270`), and the guard rejects *non*-Ethiopian endpoints —
`'Intercity bookings only run between Ethiopian yards'`
(`bookings.service.ts:218`). The only related rejections are
`'Intercity bookings cannot pin a date or schedule'` (`:771`) and
`'No route passes through this origin and destination in order'`.
→ Either the scenario is stale, or intercity was meant to be disabled and is
not. Ticket, not a test.
**S29 — there is no out-of-order checkpoint guard.** `recordCheckpoint`
(`train-scheduling.service.ts:3681`) validates only: schedule exists, status is
DISPATCHED, and the station is on the route. Nothing compares `sequenceNo`
against the highest already logged, so "Arrived Adama" before "Passed Meiso" is
accepted. `currentSequenceNo` is a `Math.max` (`:3643`) so the timeline does not
visibly regress — which *masks* the real damage: the position fix at `:3741`
moves the locomotives, every wagon on the schedule, and the built train to that
station's yard. A stray backward checkpoint silently relocates rolling stock.
→ Real bug. Worth a spec that documents current behaviour as `.skip` plus a
ticket, rather than an assertion that pretends the guard exists.
**S36 — `importReleaseGranted` is NOT gated on the second duty.** The scenario
expects release to stay false until the second duty settles. `importReleaseGranted`
is computed from the `IMPORT_RELEASE_GRANTED` milestone
(`booking-clearance.service.ts:368`), which completes purely by uploading a file
with fieldname `import_release`. `completeByDocTrigger`
(`clearance-milestone.service.ts:430`) performs **no** precondition check, and
`assertPriorCompleteOnMilestones` only walks *pre-booking* milestones
(`clearance-workflow.service.ts:119`) — so all 17 post-`DO_COLLECTED` codes,
including the whole `T1_CLOSED → RISK_ASSIGNED → SECOND_DUTY_* →
IMPORT_RELEASE_GRANTED` tail, are unordered.
→ Release can be granted with `SECOND_DUTY_PAID` still PENDING. Real gap.
**S40 — hazardous quantity is NOT rejected, it is silently clamped.** The
scenario expects `hazardousQuantity=12` on a `quantity=10` line to be rejected.
The DTO has `@Min(0)` and no `@Max` (`create-booking.dto.ts:60`), and the
repository clamps to `0..quantity` (`bookings.repository.ts:217`): the booking
is created 201 with the value truncated, no warning. Reefer behaves identically.
Note `returnQuantity` — same layer, same shape of data — *does* throw
(`contract-booking.service.ts:1740`), so the pattern exists and these two just
do not use it.
→ Real gap. A test asserting rejection would fail today.
**S40 — reefer is NOT derived from container type.** The scenario expects
`reeferQuantity` forced to 0 for DRY types. No such logic exists; a DRY type
with `reeferQuantity > 0` is an explicitly supported state and applies the
surcharge anyway (`booking.entity.ts:384`, `booking-pricing.service.ts:402`).
## Flag-dependent — assert the flag, or the test is vacuous
**S13/S14/S18 "export never splits"** holds only while
`FREIGHT_EXPORT_SPLIT !== "true"` (`booking-batch.service.ts:394`). With the
flag on, `isSplitEligible` admits EXPORT (`:2558`) and `tryExportPartialOffer`
(`:1240`) runs. The export specs must assert the flag is off, or they silently
stop testing whole-or-nothing the day someone flips it.
## Known type hole (not scenario-blocking)
Last-mile and first-mile billing write the literal `'last_mile'` / `'first_mile'`
cast past the type checker (`last-mile-invoice.service.ts:41`), while
`Freight.InvoiceSource.LastMile` is `"lastmile"`. `invoices.source` is a plain
varchar with no constraint, so both spellings persist. Writes and reads agree
within each module so billing works — but S39's "invoice source LASTMILE"
assertion must match `'last_mile'`, not the enum value.

* are valid — "available days depend on the wagons your cargo needs";
* 3. a blank cargo description aborts the submit SILENTLY (no modal, no
* toast, no request) — cy.fillCargoDescription covers it.
*
* Leaves the browser on /bookings/:id, the page the form redirects to.

/**
* GROUP 10 · S40 — line-level validation and the re-priced booking.

* - return quantity above the line quantity (enforced)
* - a re-priced booking parks with ZERO capacity footprint
*
* ── TWO SCENARIO CORRECTIONS (see SCENARIO_ENGINE_NOTES.md) ────────────────
*
* S40 expects `hazardousQuantity: 12` on a `quantity: 10` line to be REJECTED.
* It is not. The DTO carries only @IsOptional @IsInt @Min(0) with no @Max
* (create-booking.dto.ts:60-76), and the repository CLAMPS instead of throwing
* (bookings.repository.ts:217): the booking is created 201 with the value
* silently truncated to 10. Reefer behaves identically.
*
* Worth noting because it is the same layer and the same shape of data:
* `returnQuantity` DOES throw, with a precise message
* (contract-booking.service.ts:1740). So the pattern exists in the codebase —
* hazardous and reefer just do not use it. That asymmetry is asserted below,
* because it is the clearest evidence the clamp is an oversight rather than a
* deliberate design.
*
* S40 also expects reefer to be forced to 0 for DRY container types. No such
* logic exists: a DRY type with reeferQuantity > 0 is an explicitly supported
* state that applies the REEFER surcharge anyway (booking.entity.ts:384,
* booking-pricing.service.ts:402).
*
* Both are written as passing tests of CURRENT behaviour plus skipped tests of
* the DESIRED behaviour.
*
* Sequential steps per scenario — retries off.

* A/B/C are all selected by the batch and given pay windows. B and C pay. A

*
* Final consist: B 20 + C 30 + D 3 = 53/53, FULL.
* A is recoverable: its contract is untouched, so it can rebook a later day
* with no re-approval.
*
* WHAT IS DRIVEN THROUGH THE UI (this is the "visual" spec of the pair)
*
* - the whole fleet-configuration phase: the 53-wagon consist and its
* locomotives are SEEN on the Train Composition tab before any cargo
* exists, so the capacity under test is the capacity on screen;
* - D — the small booking — is booked by the customer through the real
* portal shipment form, end to end (6 containers = 6 ISO inputs);
* - every capacity verdict is read off the backoffice Priority Tracking
* tab: the "In the batch" / "Waiting list" / "Expired" lanes and the
* literal `Capacity line · 53/53 wagons · FULL` divider.
*
* WHAT STAYS ON THE API, AND WHY
*
* - A/B/C's cargo (53 wagons ≈ 106 ISO container numbers) — typing those
* through the form is minutes of keystrokes per scenario and tests the
* form, not the scheduling engine. `bookContainers` is the same helper
* every corridor spec uses.
* - PAYMENT. There is no mock/test payment path in the portal: "Pay now"
* opens a provider modal that redirects off-origin to a real gateway
* (useBookingPayment → window.location.href). Cypress cannot follow that,
* so payment is settled the way every other spec settles it — staff
* mark-paid, or the internal gateway webhook via `settleViaGateway`.
*
* Sequential steps of one journey — retries off (steps are not idempotent).

/**
* GROUP 1 · S5 — one expiry cascades into a second promotion.
*
* In the batch: A 10w + B 20w + C 23w = 53/53
* Waiting: D 8w, E 5w (priority order D before E)
*
* A never pays and EXPIRES → 10 wagons freed → D (8w) is promoted.
* D ALSO never pays and EXPIRES → its 8 wagons are freed again → the next
* top-up pass promotes E (5w), and the 3 wagons still loose are offered as a
* partial to whoever is next in the pool.
*
* The point is that ONE settle does not stop at ONE promotion:
* `fillFromWaitingList` (booking-batch.service.ts:2788) loops up to 10 rounds,
* re-running the day pool until a pass reserves nothing — because expiring an
* N-wagon booking can free room for several smaller ones, and reserving those
* can in turn leave room for the next size down. A single-pass top-up would
* strand E until the next window cycle, and this scenario would catch it.
*
* Every expiry must also leave an audit trail: each expired reservation is a
* terminal EXPIRED booking with its invoice closed out, not a silent
* disappearance.
*
* Sequential steps of one journey — retries off.

/**
* GROUP 1 · S6–S8 — a declined split, government preemption, and priority tiers.
*
* Three scenarios that all turn on WHO gets the last wagons, run against the
* 53-wagon built train (see g1-utils / seed-g1-train.sql).
*
* S6 a split offer nobody takes: the offer lapses, the booking expires
* WHOLE, and the wagons it was offered stay unsold.
* S7 government jumps the queue — by PREEMPTION, not by ranking.
* S8 commercial priority tiers decide who is offered the remainder.
*
* TWO SCENARIO CORRECTIONS (see SCENARIO_ENGINE_NOTES.md for the full write-up)
*
* S7 as written says a government booking with "institution set" gets
* +50,000 priority and therefore sorts above commercial. The bonus is real
* (GOVERNMENT_PRIORITY_BONUS = 50_000, rule-engine.service.ts:258) but it
* keys off `bookings.is_government`, not an institution lookup — and
* government does not merely outrank: it DISPLACES the lowest-priority
* commercial reservation on an already-committed train and rides unpaid.
* Government bookings are created via POST /bookings against a
* kind='government' company and promoted with /government-expedite; they
* never go through the contract wizard.
*
* S8 as written names priority tiers USD_PAYER and RAIL_AND_FORWARDING.
* Those enum values were retired with the `priority_rules` table
* (migration 1783000000000-ReplacePriorityRulesWithPriorityConfigs). The
* live model is `priority_configs`, typed WAGON | CURRENCY | CUSTOMS and
* scored by wagon-count range. The scenario's INTENT — tiered commercial
* ordering, the lowest tier getting the split — is preserved against the
* real mechanism.
*
* Sequential steps per scenario — retries off.

/**
* GROUP 2 · S9–S12 — when WEIGHT binds before slots.
*
* Group 1 kept every non-slot axis slack so wagon arithmetic was the only
* thing under test. This group inverts that: the trains pull 3500T base
* (two 1750T locomotives — pull weight ADDS UP across a set,
* train-capacity.util.ts:358) and the cargo is heavy enough that the pull
* limit runs out before the 53 slots do.
*
* THE ARITHMETIC — all of it follows from `grossWagonWeightTons` = tare + cargo
* (train-capacity.util.ts:197). The weight axis is GROSS: a locomotive hauls
* the wagon as well as what is in it. NW5 tare = 22.4T, two 20ft per wagon:
*
* heavy (28T VGM): 2 × 28 + 22.4 = 78.4T per wagon
* light (12T VGM): 2 × 12 + 22.4 = 46.4T per wagon
*
* S9 35 wagons × 78.4 = 2744.0T fits; +10 more = 3528.0T breaks 3500T.
* C is refused on WEIGHT with 18 slots still empty.
* S10 the same 3528T is admitted WHOLE on a train whose locomotives carry a
* 90T tolerance (cap 3590T). Tolerance buys a whole booking, nothing else.
* S11 with 756T of base room left, a split may size at most 9 wagons
* (705.6T) — never 10, because a split is budgeted against BASE only.
* S12 light cargo: 53 wagons weigh 2459.2T, 70% of the limit. SLOTS bind.
*
* Each scenario names the binding axis in its verdict — "FULL by weight at
* 35/53 slots" and "FULL by slots at 70% weight" are different states and a
* test that only counted wagons could not tell them apart.
*
* Fixture: seed-g2-weight.sql (TRN-G2-BASE, TRN-G2-TOL — both 53 NW5 wagons,
* so any difference in outcome is attributable to weight alone).

/**
* GROUP 3 · S13–S18 — EXPORT is first-come-first-served and whole-or-nothing.
*
* Export does not run the import batch. There is no window/doc-review/priority
* cycle: ops ACCEPT is the reservation (`acceptExportBooking` →
* `pickExportSchedule`, booking-batch.service.ts:1301), and an export booking
* must ride ONE train WHOLE — it is never split across trains and never
* part-loaded.
*
* S13 unpaid holds occupy space until they expire
* S14 whole-or-nothing packing SKIPS a booking that cannot fit, and takes
* smaller ones behind it
* S15 the customer chooses between two departures on the same day
* S16 a hold expiring flips `fits` back for the next customer
* S17 clearance holds gate one booking without touching the other 33 wagons
* S18 a booking bigger than any train is refused outright
*
* ── THE FLAG THIS GROUP DEPENDS ON ────────────────────────────────────────
*
* "Export never splits" is TRUE ONLY while FREIGHT_EXPORT_SPLIT is off
* (booking-batch.service.ts:394). With the flag on, `isSplitEligible` admits
* EXPORT (:2558) and `tryExportPartialOffer` (:1240) starts making partial
* offers — at which point S14 and S18 would silently stop testing
* whole-or-nothing and still pass for the wrong reason.
*
* The first test below asserts the flag is off. If it fails, do not "fix" the
* assertion — the rest of this group is meaningless until the flag is back off.
*
* Corridor: the reversed corridor KALITY → DJIB_PORT (ET → DJ = EXPORT),
* created by ensureExportRoute(). Export trains run on loco pairs from the
* corridor fixture; capacity is the 54-slot loco-derived figure, so this group
* is written in 54s rather than Group 1's built-train 53.
*
* Sequential steps per scenario — retries off.

/**
* GROUP 4 · S19–S21 — two trains on one import day.
*
* The import batch fills a route-DAY, not a single schedule: `topUpFill`
* re-runs the whole day pool (booking-batch.service.ts:2277, and see the
* comment at :2284 explaining why a schedule-scoped query was the bug). So a
* day with two departures is one pool with two boards, and these scenarios
* pin down how demand lands across them.
*
* S19 an oversized booking is split ACROSS the two trains (import may do
* what export cannot — see Group 3)
* S20 the batch prefers whole placements over forcing a split when a second
* train exists
* S21 the fill-first-train policy: T1 is closed out with a split before T2
* is opened up
*
* ── S20 vs S21 ARE COMPETING POLICIES ──────────────────────────────────────
*
* The original scenario document poses them as alternatives and says "pick
* one, the test asserts it". They cannot both be true of the same engine:
* S20 says a 10-wagon booking facing a 3-wagon gap on T1 goes WHOLE to T2;
* S21 says the same booking is split 3 + 7 to close T1 first.
*
* The engine's actual rule is visible in the batch loop: a booking is placed
* whole when ANY open train can take it whole, and `maybeOfferPartial` is
* reached only when `!target` — i.e. when NO train fits it
* (booking-batch.service.ts:2473-2496). That is S20. S21's fill-first policy
* is therefore NOT implemented, and its test is written `.skip` documenting
* the difference rather than asserting a behaviour that does not exist.
*
* Both trains are 53-wagon built consists (TRN-G1-1, TRN-G1-2) so the two
* boards are directly comparable.
*
* Sequential steps per scenario — retries off.

* GROUP 5 · S22–S24 — what happens to a booking that loses its seat.
*
* S22 an expired booking moves itself to the next day, no re-approval and
* no re-pricing
* S23 a booking that paid a SPLIT keeps the paid part when the REMAINDER
* later expires — the two halves have independent fates
* S24 the waiting list is walked in priority order when freed space is too
* small for its head
*
* These are the recovery paths. Group 1 proved the batch fills correctly; this
* group proves that losing is survivable — a customer whose reservation lapses
* still owns their cargo, their contract, and their place in line.
*
* Sequential steps per scenario — retries off.

/**
* GROUP 6 · S25–S29 — the train on the corridor.
*
* S25 three bookings alight at three different stations on one run
* S26 mid-corridor (Ethiopia → Ethiopia) boarding — see the correction below
* S27 tracking before the booking is on a schedule at all
* S28 a booking ARRIVES while its train is still moving
* S29 out-of-order checkpoints — see the correction below
*
* Corridor (6 stops, DJ → ET = IMPORT):
* DJIB_PORT → NAGAD → DIRE_DAWA → E2E_AWASH → MOJO → KALITY
* seq 0 1 2 3 4 5
*
* ── TWO SCENARIO CORRECTIONS (full write-up in SCENARIO_ENGINE_NOTES.md) ───
*
* S26 is INVERTED. The scenario expects a mid-corridor Ethiopian booking to be
* rejected as disabled intercity. The engine does the opposite: DOMESTIC is a
* first-class direction derived from the yards' countries
* (bookings.service.ts:270), and the guard rejects *non*-Ethiopian endpoints —
* 'Intercity bookings only run between Ethiopian yards' (:218). Per the
* decision recorded in the notes, S26 is written to assert that intercity
* WORKS, plus the two constraints that really do apply to it.
*
* S29 asserts a guard that DOES NOT EXIST. `recordCheckpoint`
* (train-scheduling.service.ts:3681) validates only that the schedule exists,
* is DISPATCHED, and that the station is on the route. Nothing compares
* sequenceNo against the highest already logged, so "Arrived Adama" before
* "Passed Meiso" is accepted. It is written below as a passing test of CURRENT
* behaviour plus a skipped test of the DESIRED behaviour, because the gap has
* teeth: the position fix at :3741 relocates the locomotives, every wagon on
* the schedule, and the built train to the out-of-order station's yard.
*
* Sequential steps per scenario — retries off.

* GROUP 8 · S34–S37 — the import customs walk.

* S34 the full clearance chain, milestone by milestone, in order
* S35 draft-declaration ping-pong: reject, correct, reject, accept
* S36 a second duty raised after arrival — see the correction below
* S37 risk level history: three assignments, oldest-first
*
* Clearance is per BOOKING and runs alongside scheduling, never inside it. A
* booking's seat on a train is not affected by where its paperwork has got to
* (Group 3 · S17 asserts the converse: paperwork does not block the train).
*
* The 28 import milestone codes are defined in
* packages/types/src/freight/contracts.ts:673 (IMPORT_MILESTONES); the split
* between contract-level and booking-level is IMPORT_PRE_BOOKING_LAST =
* 'DO_COLLECTED' (clearance-milestone.catalog.ts:93). Codes before it hang off
* the contract, codes after it off the booking.
*
* ── ONE SCENARIO CORRECTION (see SCENARIO_ENGINE_NOTES.md) ─────────────────
*
* S36 expects `importReleaseGranted` to stay false until the second duty
* settles. It does not: the milestone completes purely by uploading a file
* with fieldname `import_release`, and `completeByDocTrigger`
* (clearance-milestone.service.ts:430) performs NO precondition check.
* `assertPriorCompleteOnMilestones` only walks PRE-booking milestones
* (clearance-workflow.service.ts:119), so the entire post-DO_COLLECTED tail —
* T1_CLOSED → RISK_ASSIGNED → SECOND_DUTY_* → IMPORT_RELEASE_GRANTED — is
* unordered. Release can be granted with SECOND_DUTY_PAID still PENDING.
* Written below as current behaviour + a skipped test of the desired gate.
*
* Sequential steps per scenario — retries off.

* GROUP 9 · S38–S39 — the last leg, after the train has arrived.
*
* S38 three arrived bookings collected by the customers' own trucks
* S39 three different post-arrival paths off ONE train: EDR last-mile,
* customer self-haul, and plain yard pickup
*
* Self-haul and last-mile are mutually exclusive per booking — the engine
* enforces it both ways (mile-haulage.util.ts:38-42). What marks a booking as
* last-mile is the delivery ADDRESS alone; coordinates are stored but gate
* nothing (mile-haulage.util.ts:20-31, whose docstring explains that
* `service_types.includes_last_mile` ships true on every service type and is
* therefore useless as a signal).
*
* The truck rules under test (all in common/truck-load.util.ts):
* - MAX_CONTAINERS_PER_TRUCK = 2 → "A truck carries at most 2 containers"
* - a 40ft container fills a truck alone → "assign only 1 container to this truck"
* - a container may ride ONE truck only → 409 "already loaded onto another truck"
* - a truck may only carry THIS booking's containers
*
* Sequential steps per scenario — retries off.

-- Arrange-data for the GROUP 1 visual scenario specs (flows/g1_*.cy.ts).
-- Run AFTER seed-import-corridor.sql (it provides the corridor yards, the
-- 20FT/40FT container types + NW5 allow-list, the yard distances and the LIVE
-- CONTAINER_IMPORT rates every booking here prices against). Idempotent.
--
-- WHY A BUILT TRAIN
--
-- The Group 1 scenarios are written against a 53-wagon train. A loco-pair
-- schedule cannot hold that number: syncScheduleMaxWagons recomputes
-- max_wagons as floor(locoLength / shortest active wagon length), which the
-- corridor fixture deliberately pins at floor(760 / 13.966) = 54. A BUILT
-- train is exempt — booking-batch.service.ts:4152 takes the physical consist
-- count first and only falls back to the loco-derived figure:
--
-- const maxWagons = physicalWagons ?? capacityLimits(loco).base.wagons;
--
-- So 53 physically coupled wagons IS the capacity, and it survives the tick.
-- This is also what makes the specs' visual config phase load-bearing rather
-- than decorative: the consist staff marshal is the number the engine fills.
--
-- WEIGHT MUST NOT BIND IN GROUP 1
--
-- Group 1 tests slot arithmetic (fill, split, waitlist, priority). Weight is
-- Group 2's axis and must stay slack here or a scenario would fail for the
-- wrong reason. The locos below pull 9000T; a full 53-wagon board at the 10T
-- default VGM the specs book weighs
-- 53 × 22.4T tare + 106 × 10T cargo = 1187.2 + 1060 = 2247.2T — well under.
-- Length: 53 × 13.966 = 740.2m under the 760m cap. Slots bind, nothing else.
--
-- DEDICATED CODES
--
-- LOCO-G1-*, TRN-G1-1, WGN-G1-* are used by NO other spec. seed-import-corridor
-- re-parks loose NW5/CW4 stock between runs and sweeps whichever wagons sort
-- last into other yards, so sharing the general pool would let a sibling spec
-- steal this consist mid-run (see the header of seed-adjust-consist.sql for the
-- same hazard). Coupled wagons (train_id set) are never swept.
-- 1. Locomotive pair at DJIB_PORT — the import corridor's origin yard, which a
-- built-train schedule requires the train to be parked at. 9000T pull and 760m

-- Group 1 must never be rescued by tolerance, and Group 2 sets its own.

-- Run AFTER seed-import-corridor.sql. Idempotent.
--
-- Group 2 is the only group where WEIGHT binds before slots. Group 1's train
-- (TRN-G1-1) deliberately keeps every non-slot axis slack; this one does the
-- opposite, so the two must never share rolling stock.
--
-- THE ARITHMETIC (all from train-capacity.util.ts)
--
-- The weight axis is GROSS — a locomotive hauls the wagon as well as its
-- cargo (`grossWagonWeightTons` = tare + cargo). NW5 tare is 22.4T, and two
-- 20ft containers ride one NW5. So with a heavy VGM of 28T per container:
--
-- wagon gross = 2 × 28 + 22.4 = 78.4T ← S9's number exactly
--
-- S9 base pull 3500T: 35 wagons × 78.4 = 2744.0T ✔ fits
-- 45 wagons × 78.4 = 3528.0T ✘ over base
-- → C is blocked on WEIGHT while 18 slots still sit empty.
--
-- S10 tolerance 90T → cap 3590T: 3528 ≤ 3590, so C is admitted WHOLE.
-- Tolerance is spendable ONLY to admit a booking whole.
--
-- S11 after 2744T used, base room = 3500 − 2744 = 756T.
-- 756 / 78.4 = 9.64 → a split may size at most 9 wagons (705.6T).
-- It may NEVER reach 10 by dipping into the 90T tolerance, because
-- sizePartialOfferWagons budgets against BASE only
-- (train-capacity.util.ts:58, booking-batch.service.ts:4109).
--
-- S12 light cargo (12T/container): wagon gross = 2 × 12 + 22.4 = 46.4T.
-- 53 × 46.4 = 2459.2T — only 70% of base. SLOTS bind, not weight.
--
-- TWO LOCOMOTIVE PAIRS, ONE TRAIN EACH
--
-- Pull weight ADDS UP across a set but length takes the MINIMUM
-- (combinedLocomotiveLimits, train-capacity.util.ts:358), so a pair of 1750T
-- locos gives exactly the 3500T base the scenarios assume. Weight tolerance
-- adds up too — hence 45T each for the 90T set.
--
-- TRN-G2-BASE LOCO-G2-A/B 1750T each, tolerance 0 → 3500T base, no slack
-- TRN-G2-TOL LOCO-G2-C/D 1750T each, tolerance 45T → 3500T base + 90T
--
-- Both carry 53 NW5 wagons so the SLOT axis is identical to Group 1 and any
-- difference in outcome is attributable to weight alone.
