• The framework's seventh PBC, and the first one whose ENTIRE purpose
    is to react to events published by other PBCs. It validates the
    *consumer* side of the cross-PBC event seam that was wired up in
    commit 67406e87 (event-driven cross-PBC integration). With pbc-finance
    in place, the bus now has both producers and consumers in real PBC
    business logic — not just the wildcard EventAuditLogSubscriber that
    ships with platform-events.
    
    What landed (new module pbc/pbc-finance/, ~480 lines including tests)
      - JournalEntry entity (finance__journal_entry):
          id, code (= originating event UUID), type (AR|AP),
          partner_code, order_code, amount, currency_code, posted_at, ext.
          Unique index on `code` is the durability anchor for idempotent
          event delivery; the service ALSO existsByCode-checks before
          insert to make duplicate-event handling a clean no-op rather
          than a constraint-violation exception.
      - JournalEntryJpaRepository with existsByCode + findByOrderCode +
        findByType (the read-side filters used by the controller).
      - JournalEntryService.recordSalesConfirmed / recordPurchaseConfirmed
        take a SalesOrderConfirmedEvent / PurchaseOrderConfirmedEvent and
        write the corresponding AR/AP row. @Transactional with
        Propagation.REQUIRED so the listener joins the publisher's TX
        when the bus delivers synchronously (today) and creates a fresh
        one if a future async bus delivers from a worker thread. The
        KDoc explains why REQUIRED is the correct default and why
        REQUIRES_NEW would be wrong here.
      - OrderEventSubscribers @Component with @PostConstruct that calls
        EventBus.subscribe(SalesOrderConfirmedEvent::class.java, ...)
        and EventBus.subscribe(PurchaseOrderConfirmedEvent::class.java, ...)
        once at boot. Uses the public typed-class subscribe overload —
        NOT the platform-internal subscribeToAll wildcard helper. This
        is the API surface plug-ins will also use.
      - JournalEntryController: read-only REST under
        /api/v1/finance/journal-entries with @RequirePermission
        "finance.journal.read". Filter params: ?orderCode= and ?type=.
        Deliberately no POST endpoint — entries are derived state.
      - finance.yml metadata declaring 1 entity, 1 permission, 1 menu.
      - Liquibase changelog at distribution/.../pbc-finance/001-finance-init.xml
        + master.xml include + distribution/build.gradle.kts dep.
      - settings.gradle.kts: registers :pbc:pbc-finance.
      - 9 new unit tests (6 for JournalEntryService, 3 for
        OrderEventSubscribers) — including idempotency, dedup-by-event-id
        contract, listener-forwarding correctness via slot-captured
        EventListener invocation. Total tests: 192 → 201, 16 → 17 modules.
    
    Why this is the right shape
      - pbc-finance has zero source dependency on pbc-orders-sales,
        pbc-orders-purchase, pbc-partners, or pbc-catalog. The Gradle
        build refuses any cross-PBC dependency at configuration time —
        pbc-finance only declares api/api-v1, platform-persistence, and
        platform-security. The events and partner/item references it
        consumes all live in api.v1.event.orders / are stored as opaque
        string codes.
      - Subscribers go through EventBus.subscribe(eventType, listener),
        the public typed-class overload from api.v1.event.EventBus.
        Plug-ins use exactly this API; this PBC proves the API works
        end-to-end from a real consumer.
      - The consumer is idempotent on the producer's event id, so
        at-least-once delivery (outbox replay, future Kafka retry)
        cannot create duplicate journal entries. This makes the
        consumer correct under both the current synchronous bus and
        any future async / out-of-process bus.
      - Read-only REST API: derived state should not be writable from
        the outside. Adjustments and reversals will land later as their
        own command verbs when the real P5.9 finance build needs them,
        not as a generic create endpoint.
    
    End-to-end smoke verified against real Postgres
      - Booted on a fresh DB; the OrderEventSubscribers @PostConstruct
        log line confirms the subscription registered before any HTTP
        traffic.
      - Seeded an item, supplier, customer, location (existing PBCs).
      - Created PO PO-FIN-1 (5000 × 0.04 = 200 USD) → confirmed →
        GET /api/v1/finance/journal-entries returns ONE row:
          type=AP partner=SUP-PAPER order=PO-FIN-1 amount=200.0000 USD
      - Created SO SO-FIN-1 (50 × 0.10 = 5 USD) → confirmed →
        GET /api/v1/finance/journal-entries now returns TWO rows:
          type=AR partner=CUST-ACME order=SO-FIN-1 amount=5.0000 USD
          (plus the AP row from above)
      - GET /api/v1/finance/journal-entries?orderCode=PO-FIN-1 →
        only the AP row.
      - GET /api/v1/finance/journal-entries?type=AR → only the AR row.
      - platform__event_outbox shows 2 rows (one per confirm) both
        DISPATCHED, finance__journal_entry shows 2 rows.
      - The journal-entry code column equals the originating event
        UUID, proving the dedup contract is wired.
    
    What this is NOT (yet)
      - Not a real general ledger. No debit/credit legs, no chart of
        accounts, no period close, no double-entry invariant. P5.9
        promotes this minimal seed into a real finance PBC.
      - No reaction to ship/receive/cancel events yet — only confirm.
        Real revenue recognition (which happens at ship time for most
        accounting standards) lands with the P5.9 build.
      - No outbound api.v1.ext facade. pbc-finance does not (yet)
        expose itself to other PBCs; it is a pure consumer. When
        pbc-production needs to know "did this order's invoice clear",
        that facade gets added.

  • The buying-side mirror of pbc-orders-sales. Adds the 6th real PBC
    and closes the loop: the framework now does both directions of the
    inventory flow through the same `InventoryApi.recordMovement` facade.
    Buy stock with a PO that hits RECEIVED, ship stock with a SO that
    hits SHIPPED, both feed the same `inventory__stock_movement` ledger.
    
    What landed
    -----------
    * New Gradle subproject `pbc/pbc-orders-purchase` (16 modules total
      now). Same dependency set as pbc-orders-sales, same architectural
      enforcement — no direct dependency on any other PBC; cross-PBC
      references go through `api.v1.ext.<pbc>` facades at runtime.
    * Two JPA entities mirroring SalesOrder / SalesOrderLine:
      - `PurchaseOrder` (header) — code, partner_code (varchar, NOT a
        UUID FK), status enum DRAFT/CONFIRMED/RECEIVED/CANCELLED,
        order_date, expected_date (nullable, the supplier's promised
        delivery date), currency_code, total_amount, ext jsonb.
      - `PurchaseOrderLine` — purchase_order_id FK, line_no, item_code,
        quantity, unit_price, currency_code. Same shape as the sales
        order line; the api.v1 facade reuses `SalesOrderLineRef` rather
        than declaring a duplicate type.
    * `PurchaseOrderService.create` performs three cross-PBC validations
      in one transaction:
      1. PartnersApi.findPartnerByCode → reject if null.
      2. The partner's `type` must be SUPPLIER or BOTH (a CUSTOMER-only
         partner cannot be the supplier of a purchase order — the
         mirror of the sales-order rule that rejects SUPPLIER-only
         partners as customers).
      3. CatalogApi.findItemByCode for EVERY line.
      Then validates: at least one line, no duplicate line numbers,
      positive quantity, non-negative price, currency matches header.
      The header total is RECOMPUTED from the lines (caller's value
      ignored — never trust a financial aggregate sent over the wire).
    * State machine enforced by `confirm()`, `cancel()`, and `receive()`:
      - DRAFT → CONFIRMED   (confirm)
      - DRAFT → CANCELLED   (cancel)
      - CONFIRMED → CANCELLED (cancel before receipt)
      - CONFIRMED → RECEIVED  (receive — increments inventory)
      - RECEIVED → ×          (terminal; cancellation requires a
                                return-to-supplier flow)
    * `receive(id, receivingLocationCode)` walks every line and calls
      `inventoryApi.recordMovement(... +line.quantity reason="PURCHASE_RECEIPT"
      reference="PO:<order_code>")`. The whole operation runs in ONE
      transaction so a failure on any line rolls back EVERY line's
      already-written movement AND the order status change. The
      customer cannot end up with "5 of 7 lines received, status
      still CONFIRMED, ledger half-written".
    * New `POST /api/v1/orders/purchase-orders/{id}/receive` endpoint
      with body `{"receivingLocationCode": "WH-MAIN"}`, gated by
      `orders.purchase.receive`. The single-arg DTO has the same
      Jackson `@JsonCreator(mode = PROPERTIES)` workaround as
      `ShipSalesOrderRequest` (the trap is documented in the class
      KDoc with a back-reference to ShipSalesOrderRequest).
    * Confirm/cancel/receive endpoints carry `@RequirePermission`
      annotations (`orders.purchase.confirm`, `orders.purchase.cancel`,
      `orders.purchase.receive`). All three keys declared in the new
      `orders-purchase.yml` metadata.
    * New api.v1 facade `org.vibeerp.api.v1.ext.orders.PurchaseOrdersApi`
      + `PurchaseOrderRef`. Reuses the existing `SalesOrderLineRef`
      type for the line shape — buying and selling lines carry the
      same fields, so duplicating the ref type would be busywork.
    * `PurchaseOrdersApiAdapter` — sixth `*ApiAdapter` after Identity,
      Catalog, Partners, Inventory, SalesOrders.
    * `orders-purchase.yml` metadata declaring 2 entities, 6 permission
      keys, 1 menu entry under "Purchasing".
    
    End-to-end smoke test (the full demo loop)
    ------------------------------------------
    Reset Postgres, booted the app, ran:
    * Login as admin
    * POST /catalog/items → PAPER-A4
    * POST /partners → SUP-PAPER (SUPPLIER)
    * POST /inventory/locations → WH-MAIN
    * GET /inventory/balances?itemCode=PAPER-A4 → [] (no stock)
    * POST /orders/purchase-orders → PO-2026-0001 for 5000 sheets
      @ $0.04 = total $200.00 (recomputed from the line)
    * POST /purchase-orders/{id}/confirm → status CONFIRMED
    * POST /purchase-orders/{id}/receive body={"receivingLocationCode":"WH-MAIN"}
      → status RECEIVED
    * GET /inventory/balances?itemCode=PAPER-A4 → quantity=5000
    * GET /inventory/movements?itemCode=PAPER-A4 →
      PURCHASE_RECEIPT delta=5000 ref=PO:PO-2026-0001
    
    Then the FULL loop with the sales side from the previous chunk:
    * POST /partners → CUST-ACME (CUSTOMER)
    * POST /orders/sales-orders → SO-2026-0001 for 50 sheets
    * confirm + ship from WH-MAIN
    * GET /inventory/balances?itemCode=PAPER-A4 → quantity=4950 (5000-50)
    * GET /inventory/movements?itemCode=PAPER-A4 →
      PURCHASE_RECEIPT delta=5000  ref=PO:PO-2026-0001
      SALES_SHIPMENT   delta=-50   ref=SO:SO-2026-0001
    
    The framework's `InventoryApi.recordMovement` facade now has TWO
    callers — pbc-orders-sales (negative deltas, SALES_SHIPMENT) and
    pbc-orders-purchase (positive deltas, PURCHASE_RECEIPT) — feeding
    the same ledger from both sides.
    
    Failure paths verified:
    * Re-receive a RECEIVED PO → 400 "only CONFIRMED orders can be received"
    * Cancel a RECEIVED PO → 400 "issue a return-to-supplier flow instead"
    * Create a PO from a CUSTOMER-only partner → 400 "partner 'CUST-ONLY'
      is type CUSTOMER and cannot be the supplier of a purchase order"
    
    Regression: catalog uoms, identity users, partners, inventory,
    sales orders, purchase orders, printing-shop plates with i18n,
    metadata entities (15 now, was 13) — all still HTTP 2xx.
    
    Build
    -----
    * `./gradlew build`: 16 subprojects, 186 unit tests (was 175),
      all green. The 11 new tests cover the same shapes as the
      sales-order tests but inverted: unknown supplier, CUSTOMER-only
      rejection, BOTH-type acceptance, unknown item, empty lines,
      total recomputation, confirm/cancel state machine,
      receive-rejects-non-CONFIRMED, receive-walks-lines-with-positive-
      delta, cancel-rejects-RECEIVED, cancel-CONFIRMED-allowed.
    
    What was deferred
    -----------------
    * **RFQs** (request for quotation) and **supplier price catalogs**
      — both lay alongside POs but neither is in v1.
    * **Partial receipts**. v1's RECEIVED is "all-or-nothing"; the
      supplier delivering 4500 of 5000 sheets is not yet modelled.
    * **Supplier returns / refunds**. The cancel-RECEIVED rejection
      message says "issue a return-to-supplier flow" — that flow
      doesn't exist yet.
    * **Three-way matching** (PO + receipt + invoice). Lands with
      pbc-finance.
    * **Multi-leg transfers**. TRANSFER_IN/TRANSFER_OUT exist in the
      movement enum but no service operation yet writes both legs
      in one transaction.

  • The fifth real PBC and the first business workflow PBC. pbc-inventory
    proved a PBC could consume ONE cross-PBC facade (CatalogApi).
    pbc-orders-sales consumes TWO simultaneously (PartnersApi for the
    customer, CatalogApi for every line's item) in a single transaction —
    the most rigorous test of the modular monolith story so far. Neither
    source PBC is on the compile classpath; the Gradle build refuses any
    direct dependency. Spring DI wires the api.v1 interfaces to their
    concrete adapters at runtime.
    
    What landed
    -----------
    * New Gradle subproject `pbc/pbc-orders-sales` (15 modules total).
    * Two JPA entities, both extending `AuditedJpaEntity`:
      - `SalesOrder` (header) — code, partner_code (varchar, NOT a UUID
        FK to partners), status enum DRAFT/CONFIRMED/CANCELLED, order_date,
        currency_code (varchar(3)), total_amount numeric(18,4),
        ext jsonb. Eager-loaded `lines` collection because every read of
        the header is followed by a read of the lines in practice.
      - `SalesOrderLine` — sales_order_id FK, line_no, item_code (varchar,
        NOT a UUID FK to catalog), quantity, unit_price, currency_code.
        Per-line currency in the schema even though v1 enforces all-lines-
        match-header (so multi-currency relaxation is later schema-free).
        No `ext` jsonb on lines: lines are facts, not master records;
        custom fields belong on the header.
    * `SalesOrderService.create` performs **three independent
      cross-PBC validations** in one transaction:
      1. PartnersApi.findPartnerByCode → reject if null (covers unknown
         AND inactive partners; the facade hides them).
      2. PartnersApi result.type must be CUSTOMER or BOTH (a SUPPLIER-only
         partner cannot be the customer of a sales order).
      3. CatalogApi.findItemByCode for EVERY line → reject if null.
      Then it ALSO validates: at least one line, no duplicate line numbers,
      positive quantity, non-negative price, currency matches header.
      The header total is RECOMPUTED from the lines — the caller's value
      is intentionally ignored. Never trust a financial aggregate sent
      over the wire.
    * State machine enforced by `confirm()` and `cancel()`:
      - DRAFT → CONFIRMED   (confirm)
      - DRAFT → CANCELLED   (cancel from draft)
      - CONFIRMED → CANCELLED (cancel a confirmed order)
      Anything else throws with a descriptive message. CONFIRMED orders
      are immutable except for cancellation — the `update` method refuses
      to mutate a non-DRAFT order.
    * `update` with line items REPLACES the existing lines wholesale
      (PUT semantics for lines, PATCH for header columns). Partial line
      edits are not modelled because the typical "edit one line" UI
      gesture renders to a full re-send anyway.
    * REST: `/api/v1/orders/sales-orders` (CRUD + `/confirm` + `/cancel`).
      State transitions live on dedicated POST endpoints rather than
      PATCH-based status writes — they have side effects (lines become
      immutable, downstream PBCs will receive events in future versions),
      and sentinel-status writes hide that.
    * New api.v1 facade `org.vibeerp.api.v1.ext.orders.SalesOrdersApi`
      with `findByCode`, `findById`, `SalesOrderRef`, `SalesOrderLineRef`.
      Fifth ext.* package after identity, catalog, partners, inventory.
      Sets up the next consumers: pbc-production for work orders, pbc-finance
      for invoicing, the printing-shop reference plug-in for the
      quote-to-job-card workflow.
    * `SalesOrdersApiAdapter` runtime implementation. Cancelled orders ARE
      returned by the facade (unlike inactive items / partners which are
      hidden) because downstream consumers may legitimately need to react
      to a cancellation — release a production slot, void an invoice, etc.
    * `orders-sales.yml` metadata declaring 2 entities, 5 permission keys,
      1 menu entry.
    
    Build enforcement (still load-bearing)
    --------------------------------------
    The root `build.gradle.kts` STILL refuses any direct dependency from
    `pbc-orders-sales` to either `pbc-partners` or `pbc-catalog`. Try
    adding either as `implementation(project(...))` and the build fails
    at configuration time with the architectural violation. The
    cross-PBC interfaces live in api-v1; the concrete adapters live in
    their owning PBCs; Spring DI assembles them at runtime via the
    bootstrap @ComponentScan. pbc-orders-sales sees only the api.v1
    interfaces.
    
    End-to-end smoke test
    ---------------------
    Reset Postgres, booted the app, hit:
    * POST /api/v1/catalog/items × 2  → PAPER-A4, INK-CYAN
    * POST /api/v1/partners/partners → CUST-ACME (CUSTOMER), SUP-ONLY (SUPPLIER)
    * POST /api/v1/orders/sales-orders → 201, two lines, total 386.50
      (5000 × 0.05 + 3 × 45.50 = 250.00 + 136.50, correctly recomputed)
    * POST .../sales-orders with FAKE-PARTNER → 400 with the meaningful
      message "partner code 'FAKE-PARTNER' is not in the partners
      directory (or is inactive)"
    * POST .../sales-orders with SUP-ONLY → 400 "partner 'SUP-ONLY' is
      type SUPPLIER and cannot be the customer of a sales order"
    * POST .../sales-orders with FAKE-ITEM line → 400 "line 1: item code
      'FAKE-ITEM' is not in the catalog (or is inactive)"
    * POST /{id}/confirm → status DRAFT → CONFIRMED
    * PATCH the CONFIRMED order → 400 "only DRAFT orders are mutable"
    * Re-confirm a CONFIRMED order → 400 "only DRAFT can be confirmed"
    * POST /{id}/cancel a CONFIRMED order → status CANCELLED (allowed)
    * SELECT * FROM orders_sales__sales_order — single row, total
      386.5000, status CANCELLED
    * SELECT * FROM orders_sales__sales_order_line — two rows in line_no
      order with the right items and quantities
    * GET /api/v1/_meta/metadata/entities → 13 entities now (was 11)
    * Regression: catalog uoms, identity users, partners, inventory
      locations, printing-shop plates with i18n (Accept-Language: zh-CN)
      all still HTTP 2xx.
    
    Build
    -----
    * `./gradlew build`: 15 subprojects, 153 unit tests (was 139),
      all green. The 14 new tests cover: unknown/SUPPLIER-only/BOTH-type
      partner paths, unknown item path, empty/duplicate-lineno line
      arrays, negative-quantity early reject (verifies CatalogApi NOT
      consulted), currency mismatch reject, total recomputation, all
      three state-machine transitions and the rejected ones.
    
    What was deferred
    -----------------
    * **Sales-order shipping**. Confirmed orders cannot yet ship, because
      shipping requires atomically debiting inventory — which needs the
      movement ledger that was deferred from P5.3. The pair of chunks
      (movement ledger + sales-order shipping flow) is the natural next
      combination.
    * **Multi-currency lines**. The schema column is per-line but the
      service enforces all-lines-match-header in v1. Relaxing this is a
      service-only change.
    * **Quotes** (DRAFT-but-customer-visible) and **deliveries** (the
      thing that triggers shipping). v1 only models the order itself.
    * **Pricing engine / discounts**. v1 takes the unit price the caller
      sends. A real ERP has a price book lookup, customer-specific
      pricing, volume discounts, promotional pricing — all of which slot
      in BEFORE the line price is set, leaving the schema unchanged.
    * **Tax**. v1 totals are pre-tax. Tax calculation is its own PBC
      (and a regulatory minefield) that lands later.

  • The fourth real PBC, and the first one that CONSUMES another PBC's
    api.v1.ext facade. Until now every PBC was a *provider* of an
    ext.<pbc> interface (identity, catalog, partners). pbc-inventory is
    the first *consumer*: it injects org.vibeerp.api.v1.ext.catalog.CatalogApi
    to validate item codes before adjusting stock. This proves the
    cross-PBC contract works in both directions, exactly as guardrail #9
    requires.
    
    What landed
    -----------
    * New Gradle subproject `pbc/pbc-inventory` (14 modules total now).
    * Two JPA entities, both extending `AuditedJpaEntity`:
      - `Location` — code, name, type (WAREHOUSE/BIN/VIRTUAL), active,
        ext jsonb. Single table for all location levels with a type
        discriminator (no recursive self-reference in v1; YAGNI for the
        "one warehouse, handful of bins" shape every printing shop has).
      - `StockBalance` — item_code (varchar, NOT a UUID FK), location_id
        FK, quantity numeric(18,4). The item_code is deliberately a
        string FK that references nothing because pbc-inventory has no
        compile-time link to pbc-catalog — the cross-PBC link goes
        through CatalogApi at runtime. UNIQUE INDEX on
        (item_code, location_id) is the primary integrity guarantee;
        UUID id is the addressable PK. CHECK (quantity >= 0).
    * `LocationService` and `StockBalanceService` with full CRUD +
      adjust semantics. ext jsonb on Location goes through ExtJsonValidator
      (P3.4 — Tier 1 customisation).
    * `StockBalanceService.adjust(itemCode, locationId, quantity)`:
      1. Reject negative quantity.
      2. **Inject CatalogApi**, call `findItemByCode(itemCode)`, reject
         if null with a meaningful 400. THIS is the cross-PBC seam test.
      3. Verify the location exists.
      4. SELECT-then-save upsert on (item_code, location_id) — single
         row per cell, mutated in place when the row exists, created
         when it doesn't. Single-instance deployment makes the
         read-modify-write race window academic.
    * REST: `/api/v1/inventory/locations` (CRUD), `/api/v1/inventory/balances`
      (GET with itemCode or locationId filters, POST /adjust).
    * New api.v1 facade `org.vibeerp.api.v1.ext.inventory` with
      `InventoryApi.findStockBalance(itemCode, locationCode)` +
      `totalOnHand(itemCode)` + `StockBalanceRef`. Fourth ext.* package
      after identity, catalog, partners. Sets up the next consumers
      (sales orders, purchase orders, the printing-shop plug-in's
      "do we have enough paper for this job?").
    * `InventoryApiAdapter` runtime implementation in pbc-inventory.
    * `inventory.yml` metadata declaring 2 entities, 6 permission keys,
      2 menu entries.
    
    Build enforcement (the load-bearing bit)
    ----------------------------------------
    The root build.gradle.kts STILL refuses any direct dependency from
    pbc-inventory to pbc-catalog. Try adding `implementation(project(
    ":pbc:pbc-catalog"))` to pbc-inventory's build.gradle.kts and the
    build fails at configuration time with "Architectural violation in
    :pbc:pbc-inventory: depends on :pbc:pbc-catalog". The CatalogApi
    interface is in api-v1; the CatalogApiAdapter implementation is in
    pbc-catalog; Spring DI wires them at runtime via the bootstrap
    @ComponentScan. pbc-inventory only ever sees the interface.
    
    End-to-end smoke test
    ---------------------
    Reset Postgres, booted the app, hit:
    * POST /api/v1/inventory/locations → 201, "WH-MAIN" warehouse
    * POST /api/v1/catalog/items → 201, "PAPER-A4" sheet item
    * POST /api/v1/inventory/balances/adjust with itemCode=PAPER-A4 → 200,
      the cross-PBC catalog lookup succeeded
    * POST .../adjust with itemCode=FAKE-ITEM → 400 with the meaningful
      message "item code 'FAKE-ITEM' is not in the catalog (or is inactive)"
      — the cross-PBC seam REJECTS unknown items as designed
    * POST .../adjust with quantity=-5 → 400 "stock quantity must be
      non-negative", caught BEFORE the CatalogApi mock would be invoked
    * POST .../adjust again with quantity=7500 → 200; SELECT shows ONE
      row with id unchanged and quantity = 7500 (upsert mutates, not
      duplicates)
    * GET /api/v1/inventory/balances?itemCode=PAPER-A4 → the row, with
      scale-4 numeric serialised verbatim
    * GET /api/v1/_meta/metadata/entities → 11 entities now (was 9 before
      Location + StockBalance landed)
    * Regression: catalog uoms, identity users, partners, printing-shop
      plates with i18n (Accept-Language: zh-CN), Location custom-fields
      endpoint all still HTTP 2xx.
    
    Build
    -----
    * `./gradlew build`: 14 subprojects, 139 unit tests (was 129),
      all green. The 10 new tests cover Location CRUD + the StockBalance
      adjust path with mocked CatalogApi: unknown item rejection, unknown
      location rejection, negative-quantity early reject (verifies
      CatalogApi is NOT consulted), happy-path create, and upsert
      (existing row mutated, save() not called because @Transactional
      flushes the JPA-managed entity on commit).
    
    What was deferred
    -----------------
    * `inventory__stock_movement` append-only ledger. The current operation
      is "set the quantity"; receipts/issues/transfers as discrete events
      with audit trail land in a focused follow-up. The balance row will
      then be regenerated from the ledger via a Liquibase backfill.
    * Negative-balance / over-issue prevention. The CHECK constraint
      blocks SET to a negative value, but there's no concept of "you
      cannot ISSUE more than is on hand" yet because there is no
      separate ISSUE operation — only absolute SET.
    * Lots, batches, serial numbers, expiry dates. Plenty of printing
      shops need none of these; the ones that do can either wait for
      the lot/serial chunk later or add the columns via Tier 1 custom
      fields on Location for now.
    * Cross-warehouse transfer atomicity (debit one, credit another in
      one transaction). Same — needs the ledger.

  • The eighth cross-cutting platform service is live: plug-ins and PBCs
    now have a real Translator and LocaleProvider instead of the
    UnsupportedOperationException stubs that have shipped since v0.5.
    
    What landed
    -----------
    * New Gradle subproject `platform/platform-i18n` (13 modules total).
    * `IcuTranslator` — backed by ICU4J's MessageFormat (named placeholders,
      plurals, gender, locale-aware number/date/currency formatting), the
      format every modern translation tool speaks natively. JDK ResourceBundle
      handles per-locale fallback (zh_CN → zh → root).
    * The translator takes a list of `BundleLocation(classLoader, baseName)`
      pairs and tries them in order. For the **core** translator the chain
      is just `[(host, "messages")]`; for a **per-plug-in** translator
      constructed by VibeErpPluginManager it's
      `[(pluginClassLoader, "META-INF/vibe-erp/i18n/messages"), (host, "messages")]`
      so plug-in keys override host keys, but plug-ins still inherit
      shared keys like `errors.not_found`.
    * Critical detail: the plug-in baseName uses a path the host does NOT
      publish, because PF4J's `PluginClassLoader` is parent-first — a
      `getResource("messages.properties")` against the plug-in classloader
      would find the HOST bundle through the parent chain, defeating the
      per-plug-in override entirely. Naming the plug-in resource somewhere
      the host doesn't claim sidesteps the trap.
    * The translator disables `ResourceBundle.Control`'s automatic JVM-default
      locale fallback. The default control walks `requested → root → JVM
      default → root` which would silently serve German strings to a
      Japanese-locale request just because the German bundle exists. The
      fallback chain stops at root within a bundle, then moves to the next
      bundle location, then returns the key string itself.
    * `RequestLocaleProvider` reads the active HTTP request's
      Accept-Language via `RequestContextHolder` + the servlet container's
      `getLocale()`. Outside an HTTP request (background jobs, workflow
      tasks, MCP agents) it falls back to the configured default locale
      (`vibeerp.i18n.defaultLocale`, default `en`). Importantly, when an
      HTTP request HAS no Accept-Language header it ALSO falls back to the
      configured default — never to the JVM's locale.
    * `I18nConfiguration` exposes `coreTranslator` and `coreLocaleProvider`
      beans. Per-plug-in translators are NOT beans — they're constructed
      imperatively per plug-in start in VibeErpPluginManager because each
      needs its own classloader at the front of the resolution chain.
    * `DefaultPluginContext` now wires `translator` and `localeProvider`
      for real instead of throwing `UnsupportedOperationException`.
    
    Bundles
    -------
    * Core: `platform-i18n/src/main/resources/messages.properties` (English),
      `messages_zh_CN.properties` (Simplified Chinese), `messages_de.properties`
      (German). Six common keys (errors, ok/cancel/save/delete) and an ICU
      plural example for `counts.items`. Java 9+ JEP 226 reads .properties
      files as UTF-8 by default, so Chinese characters are written directly
      rather than as `\\uXXXX` escapes.
    * Reference plug-in: moved from the broken `i18n/messages_en-US.properties`
      / `messages_zh-CN.properties` (wrong path, hyphen-locale filenames
      ResourceBundle ignores) to the canonical
      `META-INF/vibe-erp/i18n/messages.properties` /
      `messages_zh_CN.properties` paths with underscore locale tags.
      Added a new `printingshop.plate.created` key with an ICU plural for
      `ink_count` to demonstrate non-trivial argument substitution.
    
    End-to-end smoke test
    ---------------------
    Reset Postgres, booted the app, hit POST /api/v1/plugins/printing-shop/plates
    with three different Accept-Language headers:
    * (no header)         → "Plate 'PLATE-001' created with no inks." (en-US, plug-in base bundle)
    * `Accept-Language: zh-CN` → "已创建印版 'PLATE-002' (无油墨)。" (zh-CN, plug-in zh_CN bundle)
    * `Accept-Language: de`    → "Plate 'PLATE-003' created with no inks." (de, but the plug-in
                                  ships no German bundle so it falls back to the plug-in base
                                  bundle — correct, the key is plug-in-specific)
    Regression: identity, catalog, partners, and `GET /plates` all still
    HTTP 200 after the i18n wiring change.
    
    Build
    -----
    * `./gradlew build`: 13 subprojects, 118 unit tests (was 107 / 12),
      all green. The 11 new tests cover ICU plural rendering, named-arg
      substitution, locale fallback (zh_CN → root, ja → root via NO_FALLBACK),
      cross-classloader override (a real JAR built in /tmp at test time),
      and RequestLocaleProvider's three resolution paths
      (no request → default; Accept-Language present → request locale;
      request without Accept-Language → default, NOT JVM locale).
    * The architectural rule still enforced: platform-plugins now imports
      platform-i18n, which is a platform-* dependency (allowed), not a
      pbc-* dependency (forbidden).
    
    What was deferred
    -----------------
    * User-preferred locale from the authenticated user's profile row is
      NOT in the resolution chain yet — the `LocaleProvider` interface
      leaves room for it but the implementation only consults
      Accept-Language and the configured default. Adding it slots in
      between request and default without changing the api.v1 surface.
    * The metadata translation overrides table (`metadata__translation`)
      is also deferred — the `Translator` JavaDoc mentions it as the
      first lookup source, but right now keys come from .properties files
      only. Once Tier 1 customisation lands (P3.x), key users will be able
      to override any string from the SPA without touching code.

  • The third real PBC. Validates the modular-monolith template against a
    parent-with-children aggregate (Partner → Addresses → Contacts), where
    the previous two PBCs only had single-table or two-independent-table
    shapes.
    
    What landed
    -----------
    * New Gradle subproject `pbc/pbc-partners` (12 modules total now).
    * Three JPA entities, all extending `AuditedJpaEntity`:
      - `Partner` — code, name, type (CUSTOMER/SUPPLIER/BOTH), tax_id,
        website, email, phone, active, ext jsonb. Single-table for both
        customers and suppliers because the role flag is a property of
        the relationship, not the organisation.
      - `Address` — partner_id FK, address_type (BILLING/SHIPPING/OTHER),
        line1/line2/city/region/postal_code/country_code (ISO 3166-1),
        is_primary. Two free address lines + structured city/region/code
        is the smallest set that round-trips through every postal system.
      - `Contact` — partner_id FK, full_name, role, email, phone, active.
        PII-tagged in metadata YAML for the future audit/export tooling.
    * Spring Data JPA repos, application services with full CRUD and the
      invariants below, REST controllers under
      `/api/v1/partners/partners` (+ nested addresses, contacts).
    * `partners-init.xml` Liquibase changelog with the three tables, FKs,
      GIN index on `partner.ext`, indexes on type/active/country.
    * New api.v1 facade `org.vibeerp.api.v1.ext.partners` with
      `PartnersApi` + `PartnerRef`. Third `ext.<pbc>` after identity and
      catalog. Inactive partners hidden at the facade boundary.
    * `PartnersApiAdapter` runtime implementation in pbc-partners, never
      leaking JPA entity types.
    * `partners.yml` metadata declaring all 3 entities, 12 permission
      keys, 1 menu entry. Picked up automatically by `MetadataLoader`.
    * 15 new unit tests across `PartnerServiceTest`, `AddressServiceTest`
      and `ContactServiceTest` (mockk-based, mirroring catalog tests).
    
    Invariants enforced in code (not blindly delegated to the DB)
    -------------------------------------------------------------
    * Partner code uniqueness — explicit check produces a 400 with a real
      message instead of a 500 from the unique-index violation.
    * Partner code is NOT updatable — every external reference uses code,
      so renaming is a data-migration concern, not an API call.
    * Partner deactivate cascades to contacts (also flipped to inactive).
      Addresses are NOT touched (no `active` column — they exist or they
      don't). Verified end-to-end against Postgres.
    * "Primary" flag is at most one per (partner, address_type). When a
      new/updated address is marked primary, all OTHER primaries of the
      same type for the same partner are demoted in the same transaction.
    * Addresses and contacts reject operations on unknown partners
      up-front to give better errors than the FK-violation.
    
    End-to-end smoke test
    ---------------------
    Reset Postgres, booted the app, hit:
    * POST /api/v1/auth/login (admin) → JWT
    * POST /api/v1/partners/partners (CUSTOMER, SUPPLIER) → 201
    * GET  /api/v1/partners/partners → lists both
    * GET  /api/v1/partners/partners/by-code/CUST-ACME → resolves
    * POST /api/v1/partners/partners (dup code) → 400 with real message
    * POST .../{id}/addresses (BILLING, primary) → 201
    * POST .../{id}/contacts → 201
    * DELETE /api/v1/partners/partners/{id} → 204; partner active=false
    * GET  .../contacts → contact ALSO active=false (cascade verified)
    * GET  /api/v1/_meta/metadata/entities → 3 partners entities present
    * GET  /api/v1/_meta/metadata/permissions → 12 partners permissions
    * Regression: catalog UoMs/items, identity users, printing-shop
      plug-in plates all still HTTP 200.
    
    Build
    -----
    * `./gradlew build`: 12 subprojects, 107 unit tests, all green
      (was 11 / 92 before this commit).
    * The architectural rule still enforced: pbc-partners depends on
      api-v1 + platform-persistence + platform-security only — no
      cross-PBC dep, no platform-bootstrap dep.
    
    What was deferred
    -----------------
    * Permission enforcement on contact endpoints (P4.3). Currently plain
      authenticated; the metadata declares the planned `partners.contact.*`
      keys for when @RequirePermission lands.
    * Per-country address structure layered on top via metadata forms
      (P3.x). The current schema is the smallest universal subset.
    * `deletePartnerCompletely` — out of scope for v1; should be a
      separate "data scrub" admin tool, not a routine API call.

  • Adds the foundation for the entire Tier 1 customization story. Core
    PBCs and plug-ins now ship YAML files declaring their entities,
    permissions, and menus; a `MetadataLoader` walks the host classpath
    and each plug-in JAR at boot, upserts the rows tagged with their
    source, and exposes them at a public REST endpoint so the future
    SPA, AI-agent function catalog, OpenAPI generator, and external
    introspection tooling can all see what the framework offers without
    scraping code.
    
    What landed:
    
    * New `platform/platform-metadata/` Gradle subproject. Depends on
      api-v1 + platform-persistence + jackson-yaml + spring-jdbc.
    
    * `MetadataYamlFile` DTOs (entities, permissions, menus). Forward-
      compatible: unknown top-level keys are ignored, so a future plug-in
      built against a newer schema (forms, workflows, rules, translations)
      loads cleanly on an older host that doesn't know those sections yet.
    
    * `MetadataLoader` with two entry points:
    
        loadCore() — uses Spring's PathMatchingResourcePatternResolver
          against the host classloader. Finds every classpath*:META-INF/
          vibe-erp/metadata/*.yml across all jars contributing to the
          application. Tagged source='core'.
    
        loadFromPluginJar(pluginId, jarPath) — opens ONE specific
          plug-in JAR via java.util.jar.JarFile and walks its entries
          directly. This is critical: a plug-in's PluginClassLoader is
          parent-first, so a classpath*: scan against it would ALSO
          pick up the host's metadata files via parent classpath. We
          saw this in the first smoke run — the plug-in source ended
          up with 6 entities (the plug-in's 2 + the host's 4) before
          the fix. Walking the JAR file directly guarantees only the
          plug-in's own files load. Tagged source='plugin:<id>'.
    
      Both entry points use the same delete-then-insert idempotent core
      (doLoad). Loading the same source twice produces the same final
      state. User-edited metadata (source='user') is NEVER touched by
      either path — it survives boot, plug-in install, and plug-in
      upgrade. This is what lets a future SPA "Customize" UI add custom
      fields without fearing they'll be wiped on the next deploy.
    
    * `VibeErpPluginManager.afterPropertiesSet()` now calls
      metadataLoader.loadCore() at the very start, then walks plug-ins
      and calls loadFromPluginJar(...) for each one between Liquibase
      migration and start(context). Order is guaranteed: core → linter
      → migrate → metadata → start. The CommandLineRunner I originally
      put `loadCore()` in turned out to be wrong because Spring runs
      CommandLineRunners AFTER InitializingBean.afterPropertiesSet(),
      so the plug-in metadata was loading BEFORE core — the wrong way
      around. Calling loadCore() inline in the plug-in manager fixes
      the ordering without any @Order(...) gymnastics.
    
    * `MetadataController` exposes:
        GET /api/v1/_meta/metadata           — all three sections
        GET /api/v1/_meta/metadata/entities  — entities only
        GET /api/v1/_meta/metadata/permissions
        GET /api/v1/_meta/metadata/menus
      Public allowlist (covered by the existing /api/v1/_meta/** rule
      in SecurityConfiguration). The metadata is intentionally non-
      sensitive — entity names, permission keys, menu paths. Nothing
      in here is PII or secret; the SPA needs to read it before the
      user has logged in.
    
    * YAML files shipped:
      - pbc-identity/META-INF/vibe-erp/metadata/identity.yml
        (User + Role entities, 6 permissions, Users + Roles menus)
      - pbc-catalog/META-INF/vibe-erp/metadata/catalog.yml
        (Item + Uom entities, 7 permissions, Items + UoMs menus)
      - reference plug-in/META-INF/vibe-erp/metadata/printing-shop.yml
        (Plate + InkRecipe entities, 5 permissions, Plates + Inks menus
        in a "Printing shop" section)
    
    Tests: 4 MetadataLoaderTest cases (loadFromPluginJar happy paths,
    mixed sections, blank pluginId rejection, missing-file no-op wipe)
    + 7 MetadataYamlParseTest cases (DTO mapping, optional fields,
    section defaults, forward-compat unknown keys). Total now
    **92 unit tests** across 11 modules, all green.
    
    End-to-end smoke test against fresh Postgres + plug-in loaded:
    
      Boot logs:
        MetadataLoader: source='core' loaded 4 entities, 13 permissions,
          4 menus from 2 file(s)
        MetadataLoader: source='plugin:printing-shop' loaded 2 entities,
          5 permissions, 2 menus from 1 file(s)
    
      HTTP smoke (everything green):
        GET /api/v1/_meta/metadata (no auth)              → 200
          6 entities, 18 permissions, 6 menus
          entity names: User, Role, Item, Uom, Plate, InkRecipe
          menu sections: Catalog, Printing shop, System
        GET /api/v1/_meta/metadata/entities                → 200
        GET /api/v1/_meta/metadata/menus                   → 200
    
      Direct DB verification:
        metadata__entity:    core=4, plugin:printing-shop=2
        metadata__permission: core=13, plugin:printing-shop=5
        metadata__menu:      core=4, plugin:printing-shop=2
    
      Idempotency: restart the app, identical row counts.
    
      Existing endpoints regression:
        GET /api/v1/identity/users (Bearer)               → 1 user
        GET /api/v1/catalog/uoms (Bearer)                  → 15 UoMs
        GET /api/v1/plugins/printing-shop/ping (Bearer)    → 200
    
    Bugs caught and fixed during the smoke test:
    
      • The first attempt loaded core metadata via a CommandLineRunner
        annotated @Order(HIGHEST_PRECEDENCE) and per-plug-in metadata
        inline in VibeErpPluginManager.afterPropertiesSet(). Spring
        runs all InitializingBeans BEFORE any CommandLineRunner, so
        the plug-in metadata loaded first and the core load came
        second — wrong order. Fix: drop CoreMetadataInitializer
        entirely; have the plug-in manager call metadataLoader.loadCore()
        directly at the start of afterPropertiesSet().
    
      • The first attempt's plug-in load used
        metadataLoader.load(pluginClassLoader, ...) which used Spring's
        PathMatchingResourcePatternResolver against the plug-in's
        classloader. PluginClassLoader is parent-first, so the resolver
        enumerated BOTH the plug-in's own JAR AND the host classpath's
        metadata files, tagging core entities as source='plugin:<id>'
        and corrupting the seed counts. Fix: refactor MetadataLoader
        to expose loadFromPluginJar(pluginId, jarPath) which opens
        the plug-in JAR directly via java.util.jar.JarFile and walks
        its entries — never asking the classloader at all. The
        api-v1 surface didn't change.
    
      • Two KDoc comments contained the literal string `*.yml` after
        a `/` character (`/metadata/*.yml`), forming the `/*` pattern
        that Kotlin's lexer treats as a nested-comment opener. The
        file failed to compile with "Unclosed comment". This is the
        third time I've hit this trap; rewriting both KDocs to avoid
        the literal `/*` sequence.
    
      • The MetadataLoaderTest's hand-rolled JAR builder didn't include
        explicit directory entries for parent paths. Real Gradle JARs
        do include them, and Spring's PathMatchingResourcePatternResolver
        needs them to enumerate via classpath*:. Fixed the test helper
        to write directory entries for every parent of each file.
    
    Implementation plan refreshed: P1.5 marked DONE. Next priority
    candidates: P5.2 (pbc-partners — third PBC clone) and P3.4 (custom
    field application via the ext jsonb column, which would unlock the
    full Tier 1 customization story).
    
    Framework state: 17→18 commits, 10→11 modules, 81→92 unit tests,
    metadata seeded for 6 entities + 18 permissions + 6 menus.

  • Adds the framework's event bus, the second cross-cutting service (after
    auth) that PBCs and plug-ins both consume. Implements the transactional
    outbox pattern from the architecture spec section 9 — events are
    written to the database in the same transaction as the publisher's
    domain change, so a publish followed by a rollback never escapes.
    This is the seam where a future Kafka/NATS bridge plugs in WITHOUT
    touching any PBC code.
    
    What landed:
    
    * New `platform/platform-events/` module:
      - `EventOutboxEntry` JPA entity backed by `platform__event_outbox`
        (id, event_id, topic, aggregate_type, aggregate_id, payload jsonb,
        status, attempts, last_error, occurred_at, dispatched_at, version).
        Status enum: PENDING / DISPATCHED / FAILED.
      - `EventOutboxRepository` Spring Data JPA repo with a pessimistic
        SELECT FOR UPDATE query for poller dispatch.
      - `ListenerRegistry` — in-memory subscription holder, indexed both
        by event class (Class.isInstance) and by topic string. Supports
        a `**` wildcard for the platform's audit subscriber. Backed by
        CopyOnWriteArrayList so dispatch is lock-free.
      - `EventBusImpl` — implements the api.v1 EventBus. publish() writes
        the outbox row AND synchronously delivers to in-process listeners
        in the SAME transaction. Marked Propagation.MANDATORY so the bus
        refuses to publish outside an existing transaction (preventing
        publish-and-rollback leaks). Listener exceptions are caught and
        logged; the outbox row still commits.
      - `OutboxPoller` — Spring @Scheduled component that runs every 5s,
        drains PENDING / FAILED rows under a pessimistic lock, marks them
        DISPATCHED. v0.5 has no real external dispatcher — the poller is
        the seam where Kafka/NATS plugs in later.
      - `EventBusConfiguration` — @EnableScheduling so the poller actually
        runs. Lives in this module so the seam activates automatically
        when platform-events is on the classpath.
      - `EventAuditLogSubscriber` — wildcard subscriber that logs every
        event at INFO. Demo proof that the bus works end-to-end. Future
        versions replace it with a real audit log writer.
    
    * `platform__event_outbox` Liquibase changeset (platform-events-001):
      table + unique index on event_id + index on (status, created_at) +
      index on topic.
    
    * DefaultPluginContext.eventBus is no longer a stub that throws —
      it's now the real EventBus injected by VibeErpPluginManager.
      Plug-ins can publish and subscribe via the api.v1 surface. Note:
      subscriptions are NOT auto-scoped to the plug-in lifecycle in v0.5;
      a plug-in that wants its subscriptions removed on stop() must call
      subscription.close() explicitly. Auto-scoping lands when per-plug-in
      Spring child contexts ship.
    
    * pbc-identity now publishes `UserCreatedEvent` after a successful
      UserService.create(). The event class is internal to pbc-identity
      (not in api.v1) — other PBCs subscribe by topic string
      (`identity.user.created`), not by class. This is the right tradeoff:
      string topics are stable across plug-in classloaders, class equality
      is not, and adding every event class to api.v1 would be perpetual
      surface-area bloat.
    
    Tests: 13 new unit tests (9 EventBusImplTest + 4 OutboxPollerTest)
    plus 2 new UserServiceTest cases that verify the publish happens on
    the happy path and does NOT happen when create() rejects a duplicate.
    Total now 76 unit tests across the framework, all green.
    
    End-to-end smoke test against fresh Postgres with the plug-in loaded
    (everything green):
    
      EventAuditLogSubscriber subscribed to ** at boot
      Outbox empty before any user create                      ✓
      POST /api/v1/auth/login                                  → 200
      POST /api/v1/identity/users (create alice)               → 201
      Outbox row appears with topic=identity.user.created,
        status=PENDING immediately after create                ✓
      EventAuditLogSubscriber log line fires synchronously
        inside the create transaction                          ✓
      POST /api/v1/identity/users (create bob)                 → 201
      Wait 8s (one OutboxPoller cycle)
      Both outbox rows now DISPATCHED, dispatched_at set       ✓
      Existing PBCs still work:
        GET /api/v1/identity/users → 3 users                   ✓
        GET /api/v1/catalog/uoms → 15 UoMs                     ✓
      Plug-in still works:
        GET /api/v1/plugins/printing-shop/ping → 200           ✓
    
    The most important assertion is the synchronous audit log line
    appearing on the same thread as the user creation request. That
    proves the entire chain — UserService.create() → eventBus.publish()
    → EventBusImpl writes outbox row → ListenerRegistry.deliver()
    finds wildcard subscriber → EventAuditLogSubscriber.handle()
    logs — runs end-to-end inside the publisher's transaction.
    The poller flipping PENDING → DISPATCHED 5s later proves the
    outbox + poller seam works without any external dispatcher.
    
    Bug encountered and fixed during the smoke test:
    
      • EventBusImplTest used `ObjectMapper().registerKotlinModule()`
        which doesn't pick up jackson-datatype-jsr310. Production code
        uses Spring Boot's auto-configured ObjectMapper which already
        has jsr310 because spring-boot-starter-web is on the classpath
        of distribution. The test setup was the only place using a bare
        mapper. Fixed by switching to `findAndRegisterModules()` AND
        by adding jackson-datatype-jsr310 as an explicit implementation
        dependency of platform-events (so future modules that depend on
        the bus without bringing web in still get Instant serialization).
    
    What is explicitly NOT in this chunk:
    
      • External dispatcher (Kafka/NATS bridge) — the poller is a no-op
        that just marks rows DISPATCHED. The seam exists; the dispatcher
        is a future P1.7.b unit.
      • Exponential backoff on FAILED rows — every cycle re-attempts.
        Real backoff lands when there's a real dispatcher to fail.
      • Dead-letter queue — same.
      • Per-plug-in subscription auto-scoping — plug-ins must close()
        explicitly today.
      • Async / fire-and-forget publish — synchronous in-process only.

  • The reference printing-shop plug-in now actually does something:
    its main class registers two HTTP endpoints during start(context),
    and a real curl to /api/v1/plugins/printing-shop/ping returns the
    JSON the plug-in's lambda produced. End-to-end smoke test 10/10
    green. This is the chunk that turns vibe_erp from "an ERP app
    that has a plug-in folder" into "an ERP framework whose plug-ins
    can serve traffic".
    
    What landed:
    
    * api.v1 — additive (binary-compatible per the api.v1 stability rule):
      - org.vibeerp.api.v1.plugin.HttpMethod (enum)
      - org.vibeerp.api.v1.plugin.PluginRequest (path params, query, body)
      - org.vibeerp.api.v1.plugin.PluginResponse (status + body)
      - org.vibeerp.api.v1.plugin.PluginEndpointHandler (fun interface)
      - org.vibeerp.api.v1.plugin.PluginEndpointRegistrar (per-plugin
        scoped, register(method, path, handler))
      - PluginContext.endpoints getter with default impl that throws
        UnsupportedOperationException so the addition is binary-compatible
        with plug-ins compiled against earlier api.v1 builds.
    
    * platform-plugins — three new files:
      - PluginEndpointRegistry: process-wide registration storage. Uses
        Spring's AntPathMatcher so {var} extracts path variables.
        Synchronized mutation. Exact-match fast path before pattern loop.
        Rejects duplicate (method, path) per plug-in. unregisterAll(plugin)
        on shutdown.
      - ScopedPluginEndpointRegistrar: per-plugin wrapper that tags every
        register() call with the right plugin id. Plug-ins cannot register
        under another plug-in's namespace.
      - PluginEndpointDispatcher: single Spring @RestController at
        /api/v1/plugins/{pluginId}/** that catches GET/POST/PUT/PATCH/DELETE,
        asks the registry for a match, builds a PluginRequest, calls the
        handler, serializes the response. 404 on no match, 500 on handler
        throw (logged with stack trace).
      - DefaultPluginContext: implements PluginContext with a real
        SLF4J-backed logger (every line tagged with the plug-in id) and
        the scoped endpoint registrar. The other six services
        (eventBus, transaction, translator, localeProvider,
        permissionCheck, entityRegistry) throw UnsupportedOperationException
        with messages pointing at the implementation plan unit that will
        land each one. Loud failure beats silent no-op.
    
    * VibeErpPluginManager — after PF4J's startPlugins() now walks every
      loaded plug-in, casts the wrapper instance to api.v1.plugin.Plugin,
      and calls start(context) with a freshly-built DefaultPluginContext.
      Tracks the started set so destroy() can call stop() and
      unregisterAll() in reverse order. Catches plug-in start failures
      loudly without bringing the framework down.
    
    * Reference plug-in (PrintingShopPlugin):
      - Now extends BOTH org.pf4j.Plugin (so PF4J's loader can instantiate
        it via the Plugin-Class manifest entry) AND
        org.vibeerp.api.v1.plugin.Plugin (so the host's vibe_erp lifecycle
        hook can call start(context)). Uses Kotlin import aliases to
        disambiguate the two `Plugin` simple names.
      - In start(context), registers two endpoints:
          GET /ping — returns {plugin, version, ok, message}
          GET /echo/{name} — extracts path variable, echoes it back
      - The /echo handler proves path-variable extraction works end-to-end.
    
    * Build infrastructure:
      - reference-customer/plugin-printing-shop now has an `installToDev`
        Gradle task that builds the JAR and stages it into <repo>/plugins-dev/.
        The task wipes any previous staged copies first so renaming the JAR
        on a version bump doesn't leave PF4J trying to load two versions.
      - distribution's `bootRun` task now (a) depends on `installToDev`
        so the staging happens automatically and (b) sets workingDir to
        the repo root so application-dev.yaml's relative
        `vibeerp.plugins.directory: ./plugins-dev` resolves to the right
        place. Without (b) bootRun's CWD was distribution/ and PF4J found
        "No plugins" — which is exactly the bug that surfaced in the first
        smoke run.
      - .gitignore now excludes /plugins-dev/ and /files-dev/.
    
    Tests: 12 new unit tests for PluginEndpointRegistry covering literal
    paths, single/multi path variables, duplicate registration rejection,
    literal-vs-pattern precedence, cross-plug-in isolation, method
    matching, and unregisterAll. Total now 61 unit tests across the
    framework, all green.
    
    End-to-end smoke test against fresh Postgres + the plug-in JAR
    loaded by PF4J at boot (10/10 passing):
      GET /api/v1/plugins/printing-shop/ping (no auth)         → 401
      POST /api/v1/auth/login                                  → access token
      GET /api/v1/plugins/printing-shop/ping (Bearer)          → 200
                                                                 {plugin, version, ok, message}
      GET /api/v1/plugins/printing-shop/echo/hello             → 200, echoed=hello
      GET /api/v1/plugins/printing-shop/echo/world             → 200, echoed=world
      GET /api/v1/plugins/printing-shop/nonexistent            → 404 (no handler)
      GET /api/v1/plugins/missing-plugin/ping                  → 404 (no plugin)
      POST /api/v1/plugins/printing-shop/ping                  → 404 (wrong method)
      GET /api/v1/catalog/uoms (Bearer)                        → 200, 15 UoMs
      GET /api/v1/identity/users (Bearer)                      → 200, 1 user
    
    PF4J resolved the JAR, started the plug-in, the host called
    vibe_erp's start(context), the plug-in registered two endpoints, and
    the dispatcher routed real HTTP traffic to the plug-in's lambdas.
    The boot log shows the full chain.
    
    What is explicitly NOT in this chunk and remains for later:
      • plug-in linter (P1.2) — bytecode scan for forbidden imports
      • plug-in Liquibase application (P1.4) — plug-in-owned schemas
      • per-plug-in Spring child context — currently we just instantiate
        the plug-in via PF4J's classloader; there is no Spring context
        for the plug-in's own beans
      • PluginContext.eventBus / transaction / translator / etc. — they
        still throw UnsupportedOperationException with TODO messages
      • Path-template precedence between multiple competing patterns
        (only literal-beats-pattern is implemented, not most-specific-pattern)
      • Permission checks at the dispatcher (Spring Security still
        catches plug-in endpoints with the global "anyRequest authenticated"
        rule, which is the right v0.5 behavior)
      • Hot reload of plug-ins (cold restart only)
    
    Bug encountered and fixed during the smoke test:
    
      • application-dev.yaml has `vibeerp.plugins.directory: ./plugins-dev`,
        a relative path. Gradle's `bootRun` task by default uses the
        subproject's directory as the working directory, so the relative
        path resolved to <repo>/distribution/plugins-dev/ instead of
        <repo>/plugins-dev/. PF4J reported "No plugins" because that
        directory was empty. Fixed by setting bootRun.workingDir =
        rootProject.layout.projectDirectory.asFile.
    
      • One KDoc comment in PluginEndpointDispatcher contained the literal
        string `/api/v1/plugins/{pluginId}/**` inside backticks. The
        Kotlin lexer doesn't treat backticks as comment-suppressing, so
        `/**` opened a nested KDoc comment that was never closed and the
        file failed to compile. Same root cause as the AuthController bug
        earlier in the session. Rewrote the line to avoid the literal
        `/**` sequence.

  • Adds the second core PBC, validating that the pbc-identity template is
    actually clonable and that the Gradle dependency rule fires correctly
    for a real second PBC.
    
    What landed:
    
    * New `pbc/pbc-catalog/` Gradle subproject. Same shape as pbc-identity:
      api-v1 + platform-persistence + platform-security only (no
      platform-bootstrap, no other pbc). The architecture rule in the root
      build.gradle.kts now has two real PBCs to enforce against.
    
    * `Uom` entity (catalog__uom) — code, name, dimension, ext jsonb.
      Code is the natural key (stable, human-readable). UomService rejects
      duplicate codes and refuses to update the code itself (would invalidate
      every Item FK referencing it). UomController at /api/v1/catalog/uoms
      exposes list, get-by-id, get-by-code, create, update.
    
    * `Item` entity (catalog__item) — code, name, description, item_type
      (GOOD/SERVICE/DIGITAL enum), base_uom_code FK, active flag, ext jsonb.
      ItemService validates the referenced UoM exists at the application
      layer (better error message than the DB FK alone), refuses to update
      code or baseUomCode (data-migration operations, not edits), supports
      soft delete via deactivate. ItemController at /api/v1/catalog/items
      with full CRUD.
    
    * `org.vibeerp.api.v1.ext.catalog.CatalogApi` — second cross-PBC facade
      in api.v1 (after IdentityApi). Exposes findItemByCode(code) and
      findUomByCode(code) returning safe ItemRef/UomRef DTOs. Inactive items
      are filtered to null at the boundary so callers cannot accidentally
      reference deactivated catalog rows.
    
    * `CatalogApiAdapter` in pbc-catalog — concrete @Component
      implementing CatalogApi. Maps internal entities to api.v1 DTOs without
      leaking storage types.
    
    * Liquibase changeset (catalog-init-001..003) creates both tables with
      unique indexes on code, GIN indexes on ext, and seeds 15 canonical
      units of measure: kg/g/t (mass), m/cm/mm/km (length), m2 (area),
      l/ml (volume), ea/sheet/pack (count), h/min (time). Tagged
      created_by='__seed__' so a future metadata uninstall sweep can
      identify them.
    
    Tests: 11 new unit tests (UomServiceTest x5, ItemServiceTest x6),
    total now 49 unit tests across the framework, all green.
    
    End-to-end smoke test against fresh Postgres via docker-compose
    (14/14 passing):
      GET /api/v1/catalog/items (no auth)            → 401
      POST /api/v1/auth/login                        → access token
      GET /api/v1/catalog/uoms (Bearer)              → 15 seeded UoMs
      GET /api/v1/catalog/uoms/by-code/kg            → 200
      POST custom UoM 'roll'                         → 201
      POST duplicate UoM 'kg'                        → 400 + clear message
      GET items                                       → []
      POST item with unknown UoM                     → 400 + clear message
      POST item with valid UoM                       → 201
      catalog__item.created_by                       → admin user UUID
                                                       (NOT __system__)
      GET /by-code/INK-CMYK-CYAN                     → 200
      PATCH item name + description                  → 200
      DELETE item                                    → 204
      GET item                                       → active=false
    
    The principal-context bridge from P4.1 keeps working without any
    additional wiring in pbc-catalog: every PBC inherits the audit
    behavior for free by extending AuditedJpaEntity. That is exactly the
    "PBCs follow a recipe, the framework provides the cross-cutting
    machinery" promise from the architecture spec.
    
    Architectural rule enforcement still active: confirmed by reading the
    build.gradle.kts and observing that pbc-catalog declares no
    :platform:platform-bootstrap and no :pbc:pbc-identity dependency. The
    build refuses to load on either violation.

  • Implements the auth unit from the implementation plan. Until now, the
    framework let any caller hit any endpoint; with the single-tenant
    refactor there is no second wall, so auth was the most pressing gap.
    
    What landed:
    
    * New `platform-security` module owns the framework's security
      primitives (JWT issuer/verifier, password encoder, Spring Security
      filter chain config, AuthenticationFailedException). Lives between
      platform-persistence and platform-bootstrap.
    
    * `JwtIssuer` mints HS256-signed access (15min) and refresh (7d) tokens
      via NimbusJwtEncoder. `JwtVerifier` decodes them back to a typed
      `DecodedToken` so PBCs never need to import OAuth2 types. JWT secret
      is read from VIBEERP_JWT_SECRET; the framework refuses to start if
      the secret is shorter than 32 bytes.
    
    * `SecurityConfiguration` wires Spring Security with JWT resource
      server, stateless sessions, CSRF disabled, and a public allowlist
      for /actuator/health, /actuator/info, /api/v1/_meta/**,
      /api/v1/auth/login, /api/v1/auth/refresh.
    
    * `PrincipalContext` (in platform-persistence/security) is the bridge
      between Spring Security's SecurityContextHolder and the audit
      listener. Bound by `PrincipalContextFilter` which runs AFTER
      BearerTokenAuthenticationFilter so SecurityContextHolder is fully
      populated. The audit listener (AuditedJpaEntityListener) now reads
      from PrincipalContext, so created_by/updated_by are real user ids
      instead of __system__.
    
    * `pbc-identity` gains `UserCredential` (separate table from User —
      password hashes never share a query plan with user records),
      `AuthService` (login + refresh, generic AuthenticationFailedException
      on every failure to thwart account enumeration), and `AuthController`
      exposing /api/v1/auth/login and /api/v1/auth/refresh.
    
    * `BootstrapAdminInitializer` runs on first boot of an empty
      identity__user table, creates an `admin` user with a random
      16-char password printed to the application logs. Subsequent
      boots see the user exists and skip silently.
    
    * GlobalExceptionHandler maps AuthenticationFailedException → 401
      with a generic "invalid credentials" body (RFC 7807 ProblemDetail).
    
    * New module also brings BouncyCastle as a runtime-only dep
      (Argon2PasswordEncoder needs it).
    
    Tests: 38 unit tests pass, including JwtRoundTripTest (issue/decode
    round trip + tamper detection + secret-length validation),
    PrincipalContextTest (ThreadLocal lifecycle), AuthServiceTest (9 cases
    covering login + refresh happy paths and every failure mode).
    
    End-to-end smoke test against a fresh Postgres via docker-compose:
      GET /api/v1/identity/users (no auth)        → 401
      POST /api/v1/auth/login (admin + bootstrap) → 200 + access/refresh
      POST /api/v1/auth/login (wrong password)    → 401
      GET  /api/v1/identity/users (Bearer)        → 200, lists admin
      POST /api/v1/identity/users (Bearer)        → 201, creates alice
      alice.created_by                            → admin's user UUID
      POST /api/v1/auth/refresh (refresh token)   → 200 + new pair
      POST /api/v1/auth/refresh (access token)    → 401 (type mismatch)
      GET  /api/v1/identity/users (garbage token) → 401
      GET  /api/v1/_meta/info (no auth, public)   → 200
    
    Plan: docs/superpowers/specs/2026-04-07-vibe-erp-implementation-plan.md
    refreshed to drop the now-dead P1.1 (RLS hook) and H1 (per-region
    tenant routing), reorder priorities so P4.1 is first, and reflect the
    single-tenant change throughout.
    
    Bug fixes encountered along the way (caught by the smoke test, not by
    unit tests — the value of running real workflows):
    
      • JwtIssuer was producing IssuedToken.expiresAt with nanosecond
        precision but JWT exp is integer seconds; the round-trip test
        failed equality. Fixed by truncating to ChronoUnit.SECONDS at
        issue time.
      • PrincipalContextFilter was registered with addFilterAfter
        UsernamePasswordAuthenticationFilter, which runs BEFORE the
        OAuth2 BearerTokenAuthenticationFilter, so SecurityContextHolder
        was empty when the bridge filter read it. Result: every
        authenticated request still wrote __system__ in audit columns.
        Fixed by addFilterAfter BearerTokenAuthenticationFilter::class.
      • RefreshRequest is a single-String data class. jackson-module-kotlin
        interprets single-arg data classes as delegate-based creators, so
        Jackson tried to deserialize the entire JSON object as a String
        and threw HttpMessageNotReadableException. Fixed by adding
        @JsonCreator(mode = PROPERTIES) + @param:JsonProperty.

  • Design change: vibe_erp deliberately does NOT support multiple companies in
    one process. Each running instance serves exactly one company against an
    isolated Postgres database. Hosting many customers means provisioning many
    independent instances, not multiplexing them.
    
    Why: most ERP/EBC customers will not accept a SaaS where their data shares
    a database with other companies. The single-tenant-per-instance model is
    what the user actually wants the product to look like, and it dramatically
    simplifies the framework.
    
    What changed:
    - CLAUDE.md guardrail #5 rewritten from "multi-tenant from day one" to
      "single-tenant per instance, isolated database"
    - api.v1: removed TenantId value class entirely; removed tenantId from
      Entity, AuditedEntity, Principal, DomainEvent, RequestContext,
      TaskContext, IdentityApi.UserRef, Repository
    - platform-persistence: deleted TenantContext, HibernateTenantResolver,
      TenantAwareJpaTransactionManager, TenancyJpaConfiguration; removed
      @TenantId and tenant_id column from AuditedJpaEntity
    - platform-bootstrap: deleted TenantResolutionFilter; dropped
      vibeerp.instance.mode and default-tenant from properties; added
      vibeerp.instance.company-name; added VibeErpApplication @EnableJpaRepositories
      and @EntityScan so PBC repositories outside the main package are wired;
      added GlobalExceptionHandler that maps IllegalArgumentException → 400
      and NoSuchElementException → 404 (RFC 7807 ProblemDetail)
    - pbc-identity: removed tenant_id from User, repository, controller, DTOs,
      IdentityApiAdapter; updated UserService duplicate-username message and
      the matching test
    - distribution: dropped multiTenancy=DISCRIMINATOR and
      tenant_identifier_resolver from application.yaml; configured Spring Boot
      mainClass on the springBoot extension (not just bootJar) so bootRun works
    - Liquibase: rewrote platform-init changelog to drop platform__tenant and
      the tenant_id columns on every metadata__* table; rewrote
      pbc-identity init to drop tenant_id columns, the (tenant_id, *)
      composite indexes, and the per-table RLS policies
    - IdentifiersTest replaced with Id<T> tests since the TenantId tests
      no longer apply
    
    Verified end-to-end against a real Postgres via docker-compose:
      POST /api/v1/identity/users   → 201 Created
      GET  /api/v1/identity/users   → list works
      GET  /api/v1/identity/users/X → fetch by id works
      POST duplicate username       → 400 Bad Request (was 500)
      PATCH bogus id                → 404 Not Found (was 500)
      PATCH alice                   → 200 OK
      DELETE alice                  → 204, alice now disabled
    
    All 18 unit tests pass.
