# Dependency graph
requires:
  - phase: 10-01 (foundation & dependencies)
    provides: Tender / TenderSourcePollConfig Prisma models (dedupKey @unique, sourceType @unique)
  - phase: 10-02 (marketplace registration)
    provides: TendersModule skeleton, singleton doe-opendata poll config seeded on boot
  - phase: 10-03 (adapter & normalizer)
    provides: DoeOpenDataAdapter, TenderNormalizerService
  - phase: 10-04 (ingestion orchestration & scheduler)
    provides: TenderSchedulerService.setInterval()/stopJob() (no tenant arg), TenderIngestionService.pollDueSources()
provides:
  - "TendersController — GET/GET:id (global read, @UseModule-gated, never row-scoped by tenant id) + GET/PUT source-config (Roles-guarded singleton config, live-applies to the scheduler)"
  - "SourceConfigDto, TenderQueryDto — class-validator DTOs following the DKV conventions"
  - "Automated proof (controller spec) of the tenant-gated-not-scoped invariant and the live scheduler-apply on config save"
affects: [phase 11 saved searches/filter UI (consumes GET / and GET /:id as the read surface over the ingested catalog)]

    - "Global-read-gated-by-module-not-by-tenant-row: GET / and GET /:id use plain PrismaService with a where clause built only from query params (status/pagination), gated exclusively by @UseModule('tender-radar') — this is the one controller in the codebase where tenant-gated (feature visibility) and tenant-scoped (row filtering) genuinely diverge"
    - "Admin platform-config routes are Roles-guarded, not ModuleGuard-gated — configuring the shared platform-wide poll schedule is a platform-admin action, not a per-tenant module feature, so @UseModule is deliberately absent from source-config routes"
    - "Scheduler live-apply on config save: PUT /source-config calls tenderScheduler.setInterval(intervalMin) / stopJob() with no tenant argument, mirroring DkvController.saveConfig minus the per-tenant parameter (the DÖE config is a platform-wide singleton)"

  - "Comment wording avoids the literal 'tenantId' token in tenders.controller.ts (uses 'the tenant's id' / 'tenant-id' instead) — the acceptance criterion's grep-gate (`grep -c tenantId tenders.controller.ts` must return 0) checks for the literal string; an explanatory comment naming the concept using that exact identifier would trip the same false-positive class of issue Plan 10-04 documented and fixed twice already in this phase"
  - "TenderQueryDto.status defaults to 'active' at the controller layer (query DTO field itself has no default value, per plan spec — defaulting happens in listTenders(), matching DkvController's page/limit default-at-usage-site pattern)"

# Phase 10 Plan 05: Tenders Controller — Global Read + Admin Source-Config Summary

**`TendersController` wires the phase's one deliberately-divergent read surface — `GET /` and `GET /:id` gated by `@UseModule('tender-radar')` but never row-scoped by tenant — alongside `@Roles`-guarded `GET`/`PUT /source-config` that live-applies interval/active-state changes to `TenderSchedulerService`, completing INGEST-06's admin-configurable half.**

## Performance

- **Duration:** ~20 min
- **Started:** 2026-07-21
- **Completed:** 2026-07-21
- **Tasks:** 3 (Task 1 auto, Task 2 auto, Task 3 tdd="true" — spec passed immediately against Task 2's already-correct implementation)
- **Files modified:** 5 (4 created, 1 modified)

## Accomplishments

- `SourceConfigDto` (`pollIntervalMin` `@Min(5) @Max(1440)`, `isActive` `@IsBoolean`) and `TenderQueryDto` (`page`/`limit` pagination copied from `DkvHistoryQueryDto`, plus `status` `@IsIn(['active','expired'])`) — both class-validator DTOs following the exact DKV conventions (DoS-mitigation bounds, `@Type(() => Number)` query-string coercion).
- `TendersController` (`@Controller('modules/tender-radar')`):
  - `GET /` and `GET /:id` — paginated global `Tender` catalog read via plain `PrismaService`, gated only by `@UseModule('tender-radar')` (module activation), never row-scoped by a `where: { tenantId }` filter. `GET /:id` throws `NotFoundException` for a missing id.
  - `GET /source-config` / `PUT /source-config` — both `@Roles(Role.ADMIN, Role.SUPER_ADMIN)`-guarded. `PUT` upserts the singleton `doe-opendata` config, then live-applies the change to `TenderSchedulerService.setInterval(intervalMin)` (single argument, no tenant id) when active, or `stopJob()` when deactivated — satisfying INGEST-06's "applied without restart" requirement.
- `TendersController` registered in `TendersModule.controllers`; `TenderSchedulerService` (already a provider since Plan 04) resolves via DI.
- Controller spec (5 tests): proves the read path never adds a `tenantId` key to the prisma `where`, `GET /:id` 404s for a missing tender, and both config-save branches (`isActive=true`+interval / `isActive=false`) drive the scheduler exactly as specified.
- Full API test suite green (74/74), `tsc --noEmit` clean for both `apps/api` and `apps/web`, all grep gates (`UseModule` present, `tenantId` absent, `@Roles` on both admin routes) pass.

## Task Commits

Each task committed atomically:

1. **Task 1: SourceConfigDto + TenderQueryDto** — `f6e636c` (feat)
2. **Task 2: TendersController — global read (ModuleGuard) + admin source-config (Roles) + live scheduler apply** — `7b9b6b8` (feat)
3. **Task 3: Controller test — global read not tenant-scoped + admin config applies to scheduler** — `eaff1d8` (test)

**Plan metadata:** see final `docs(10-05)` commit.

## TDD Gate Compliance

- Task 3 (`tdd="true"`): the spec (`eaff1d8`, `test(10-05): ...`) passed on first run, immediately after being written — **this is expected, not an unexpected-pass violation of the RED-GREEN gate.** Task 2's `feat` commit (`7b9b6b8`) already implemented the tenant-gated-not-scoped read path and the scheduler live-apply correctly; Task 3's test locks in and regression-proofs that already-correct behavior via genuine assertions on the prisma `where` clause and scheduler mock calls, rather than driving new production code. This plan's frontmatter is `type: execute` with a per-task `tdd="true"` flag (not a full `type: tdd` plan), matching the exact precedent documented in Plan 10-04's Task 3 — the strict "investigate a passing RED" rule applies to full-plan TDD gates, not this per-task flag usage.
- No REFACTOR commit was needed — the spec passed cleanly on first write, no post-green cleanup required.

## Files Created/Modified

- `apps/api/src/tenders/dto/source-config.dto.ts` — `pollIntervalMin` (`@IsOptional @IsInt @Min(5) @Max(1440)`), `isActive` (`@IsOptional @IsBoolean`)
- `apps/api/src/tenders/dto/tender-query.dto.ts` — `page`/`limit` pagination (`@Type(() => Number)` coercion, `@Min(1)`, `limit @Max(100)`) + `status` (`@IsOptional @IsIn(['active','expired'])`)
- `apps/api/src/tenders/tenders.controller.ts` — `TendersController`: `GET /`, `GET /:id` (global, `@UseModule`-gated), `GET /source-config`, `PUT /source-config` (`@Roles`-guarded, scheduler live-apply)
- `apps/api/src/tenders/tenders.controller.spec.ts` — 5 tests: no-tenantId read-path assertion, detail found/404, `setInterval(30)` single-arg assertion, `stopJob()` assertion
- `apps/api/src/tenders/tenders.module.ts` — `TendersController` added to `controllers`

## Decisions Made

- **No intermediate service layer for the controller** — `TendersController` talks to `PrismaService` and `TenderSchedulerService` directly. The plan's `files_modified` list and PATTERNS.md's controller sketch show no `TenderConfigService`/`TenderQueryService`; the source-config upsert and the paginated global read are simple enough that an intermediate service would be premature indirection for this plan's scope. `TenderIngestionService`/`TenderSchedulerService` remain the sole business-logic services (Plan 04).
- **Comment wording avoids the literal `tenantId` token** in `tenders.controller.ts` (rephrased as "the tenant's id" / "tenant-id" throughout) — the acceptance criterion's grep gate (`grep -c tenantId tenders.controller.ts` must return 0) checks for the literal string, and an explanatory comment naming the concept with that exact identifier would trip the same false-positive class of issue Plan 10-04 documented (and auto-fixed twice) in this phase. Caught during Task 2's own verification pass before committing.
- **`TenderQueryDto.status` has no DTO-level default** — matching `DkvController`'s existing `page ?? 1` / `limit ?? 20` pattern, the `'active'`-only default is applied at the controller call site (`query.status ?? 'active'`), not baked into the DTO class itself.

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 1 - Bug] `@Body()` decorator missing on `saveSourceConfig`'s parameter**
- **Found during:** Task 2 authoring (caught before running verification)
- **Issue:** Initial draft of `saveSourceConfig(dto: SourceConfigDto)` omitted the `@Body()` parameter decorator, which would have left `dto` as `undefined` at runtime (NestJS only populates decorated parameters).
- **Fix:** Added `@Body()` and its import from `@nestjs/common`.
- **Files modified:** `apps/api/src/tenders/tenders.controller.ts`
- **Commit:** folded into `7b9b6b8` (Task 2 commit, caught and fixed before commit)

**2. [Rule 1 - Bug] Literal `tenantId` token in explanatory comments tripped the plan's own grep-gate acceptance criterion**
- **Found during:** Task 2 verification (`grep -c tenantId tenders.controller.ts` initially returned 4, not the required 0)
- **Issue:** Doc comments explaining the tenant-gated-not-scoped divergence used the literal word "tenantId" to describe what the code does NOT do — the same class of false-positive documented twice in Plan 10-04's Deviations (grep-gate assertions check for the literal string, regardless of whether it appears in code or in a comment explaining its absence).
- **Fix:** Reworded all four occurrences to "the tenant's id" / "tenant-id" (with an explicit space/hyphen breaking the literal token match) while preserving the exact same explanatory meaning.
- **Files modified:** `apps/api/src/tenders/tenders.controller.ts`
- **Verification:** `grep -c tenantId tenders.controller.ts` → 0; `tsc --noEmit` clean; full spec suite still green.
- **Committed in:** `7b9b6b8` (Task 2 commit, caught and fixed before commit)

**3. [Rule 3 - Blocking] `tsc` type errors in the controller spec's mock typing**
- **Found during:** Task 3 post-write `tsc --noEmit` verification
- **Issue:** `prisma.tender.findMany`/`count` fakes were declared as zero-argument `vi.fn(async () => ...)`, which TypeScript inferred as a `[]`-length call-args tuple — `mock.calls[0][0]` then failed with "Tuple type '[]' of length '0' has no element at index '0'".
- **Fix:** Added an explicit optional `_args?: any` parameter to both fakes so `mock.calls[0][0]` type-checks.
- **Files modified:** `apps/api/src/tenders/tenders.controller.spec.ts`
- **Verification:** `tsc --noEmit` clean; `pnpm test -- tenders.controller` still green (5/5).
- **Committed in:** `eaff1d8` (Task 3 commit, caught and fixed before commit)

---

**Total deviations:** 3 auto-fixed (2 Bugs, 1 Blocking — all caught and fixed inline before their respective commits, zero scope creep, zero behavior change beyond the fixes themselves)

## Issues Encountered

None beyond the three documented deviations above. Local Docker Postgres stack (per environment context) was not needed — the controller spec uses in-memory prisma-shaped fakes, matching this phase's established test convention (10-04's ingestion/scheduler specs), so no live-DB dependency was introduced.

## User Setup Required

None — no external service configuration required. The local Docker stack (`tessera-ctl-api-1`/`-db-1`) was left running unmodified; restarting/rebuilding it to pick up these code changes (so the new `/modules/tender-radar` routes are actually reachable over HTTP) is left to the user per project convention.

## Next Phase Readiness

- INGEST-06 is now fully complete: the platform-wide poll interval is admin-readable/writable via `GET`/`PUT /modules/tender-radar/source-config`, and saving live-applies to the running scheduler without a restart (Plan 04 built the scheduler mechanics; this plan wires the admin-facing surface to it).
- `GET /modules/tender-radar` and `GET /modules/tender-radar/:id` give Phase 11 a ready-made, paginated, `@UseModule`-gated read surface over the ingested global catalog — Phase 11's saved-searches/filter UI can consume these directly and layer richer filtering (region/CPV — FILTER-*) on top without touching the tenant-gated-not-scoped invariant established here.
- No open threat-model items from this plan carry forward unmitigated: T-10-13 (Elevation of Privilege on `PUT /source-config`) is mitigated by `@Roles(Role.ADMIN, Role.SUPER_ADMIN)` + the global `RolesGuard`; T-10-14 (Broken Access Control on `GET /tenders`) is mitigated by `@UseModule('tender-radar')` and proven by the no-tenantId controller test; T-10-15 (Input Validation DoS) is mitigated by `SourceConfigDto`/`TenderQueryDto`'s class-validator bounds.
- No blockers for the next phase (11, saved searches/filter UI over this ingested catalog).
