# Cleanup Batch (Tier A + B) Implementation Plan
|
||||||
|
|
||||||
|
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
|
||||||
|
|
||||||
|
**Goal:** Close the deferred backlog's fix-items — PATCH allowlist hardening + a11y/copy polish (Tier A), and the two design tradeoffs the user chose to fix properly: per-seed discovery scoring and a persisted scan worklist (Tier B).
|
||||||
|
|
||||||
|
**Architecture:** Tier A is small web edits to two Next.js route handlers and one client component. Tier B adds two additive tables via one Prisma migration: `DiscoverySeedContribution` (normalizes discovery scores so a suggestion's score = sum of every seed's latest contribution, independent of chunk/sweep boundaries) and `ScanWorkItem` (a frozen worklist so `scan_chunk` pops by indexed cursor instead of re-walking the tree each chunk). All worker DB access is raw psycopg SQL.
|
||||||
|
|
||||||
|
**Tech Stack:** Next.js (App Router, TypeScript, vitest, node test env), Prisma (migration source of truth), Python worker (psycopg, pytest against `lyra_test`).
|
||||||
|
|
||||||
|
## Global Constraints
|
||||||
|
|
||||||
|
- Tests run against `lyra_test` only; a guard refuses non-`*_test` DBs. Never point at live `lyra`.
|
||||||
|
- Web vitest env is **node, not jsdom** — no DOM-render tests. UI-only changes (aria-label, copy) are verified by `tsc` + build + Playwright, not unit tests.
|
||||||
|
- Preserve existing `aria-label`s / button text — web route tests and Playwright key off them.
|
||||||
|
- Worker SQL uses quoted PascalCase table/column identifiers (`"DiscoverySuggestion"`, `"seedMbid"`).
|
||||||
|
- Discovery `_upsert_artist`/`_upsert_album` MUST keep their `WHERE "DiscoverySuggestion".status = 'pending'` guard (dismissed/wanted rows are never revived).
|
||||||
|
- Frequent commits: one per task minimum, following the TDD step order.
|
||||||
|
- Migration reaches live `lyra` via the web entrypoint's `migrate deploy` on rebuild; no `down -v`, ever.

## File Structure
|
||||||
|
|
||||||
|
**Tier A (web):**
|
||||||
|
- `web/src/app/api/monitor/config/route.ts` — PATCH allowlist → `hasOwnProperty`.
|
||||||
|
- `web/src/app/api/discover/config/route.ts` — PATCH allowlist → `hasOwnProperty`.
|
||||||
|
- `web/src/app/api/monitor/config/route.test.ts` — prototype-chain rejection test.
|
||||||
|
- `web/src/app/api/discover/config/route.test.ts` — prototype-chain rejection test.
|
||||||
|
- `web/src/app/api/config/route.test.ts` — add `constructor` case.
|
||||||
|
- `web/src/app/settings/settings-form.tsx` — Monitor toggle `aria-label` + eyebrow copy.
|
||||||
|
|
||||||
|
**Tier B (schema + worker):**
|
||||||
|
- `web/prisma/schema.prisma` — add both models.
|
||||||
|
- `web/prisma/migrations/<ts>_add_contributions_and_scan_worklist/migration.sql` — CREATE TABLE ×2.
|
||||||
|
- `worker/tests/conftest.py` — clean the two new tables between tests.
|
||||||
|
- `worker/lyra_worker/discovery.py` — contributions write + recompute.
|
||||||
|
- `worker/tests/test_discovery.py` — new cross-chunk / partial-sweep / drop-off tests.
|
||||||
|
- `worker/lyra_worker/scan.py` — `build_worklist` / new `scan_chunk` / `clear_worklist` / reimplemented `scan_library`.
|
||||||
|
- `worker/lyra_worker/main.py` — `maybe_run_scan` drives the worklist by `scan.id`.
|
||||||
|
- `worker/tests/test_scan_chunk.py` — rewritten to the worklist API.
|
||||||

## Task 1: Tier A1 + A3 — PATCH allowlist hardening + tests
|
||||||
|
|
||||||
|
**Files:**
|
||||||
|
- Modify: `web/src/app/api/monitor/config/route.ts:26-28`
|
||||||
|
- Modify: `web/src/app/api/discover/config/route.ts:28-30`
|
||||||
|
- Test: `web/src/app/api/monitor/config/route.test.ts`
|
||||||
|
- Test: `web/src/app/api/discover/config/route.test.ts`
|
||||||
|
- Test: `web/src/app/api/config/route.test.ts` (add one case)
|
||||||
|
|
||||||
|
**Interfaces:**
|
||||||
|
- Consumes: nothing new.
|
||||||
|
- Produces: nothing consumed by later tasks.
|
||||||
|
|
||||||
|
**Background:** Both PATCH routes filter with `([k]) => k in DEFAULTS`, which walks the prototype chain, so a body key of `__proto__` or `constructor` passes the filter and writes a junk `Config` row (harmless — no delete — but inconsistent with the DELETE handler at `web/src/app/api/config/route.ts:51`, which already uses `Object.prototype.hasOwnProperty.call(...)`).
|
||||||
|
|
||||||
|
- [ ] **Step 1: Write the failing test — monitor PATCH rejects prototype-chain keys**
|
||||||
|
|
||||||
|
Append to `web/src/app/api/monitor/config/route.test.ts` (mirror the file's existing PATCH test style — read the top of the file for its `patchReq` helper; if none exists, add one like below):
|
||||||
|
|
||||||
|
```ts
|
||||||
|
function patchReq(body: unknown) {
|
||||||
|
return new Request("http://localhost/api/monitor/config", {
|
||||||
|
method: "PATCH",
|
||||||
|
headers: { "content-type": "application/json" },
|
||||||
|
body: JSON.stringify(body),
|
||||||
|
});
|
||||||
|
}
|
||||||
|
|
||||||
|
it("ignores prototype-chain keys (__proto__, constructor) and writes no Config row", async () => {
|
||||||
|
const before = await prisma.config.count();
|
||||||
|
const res = await PATCH(patchReq({ __proto__: "x", constructor: "y" }));
|
||||||
|
expect((await res.json()).updated).toBe(0);
|
||||||
|
expect(await prisma.config.count()).toBe(before);
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
Ensure `PATCH` and `prisma` are imported at the top of the test file (`import { GET, PATCH } from "./route";` and `import { prisma } from "@/lib/db";`).
|
||||||
|
|
||||||
|
- [ ] **Step 2: Run it to verify it fails**
|
||||||
|
|
||||||
|
Run: `cd web && npx vitest run src/app/api/monitor/config/route.test.ts`
|
||||||
|
Expected: FAIL — `updated` is `2` (or a Config row was written), because `__proto__`/`constructor` pass `k in DEFAULTS`.
|
||||||
|
|
||||||
|
- [ ] **Step 3: Harden both PATCH routes**
|
||||||
|
|
||||||
|
In `web/src/app/api/monitor/config/route.ts` change the filter:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
const entries = Object.entries((body ?? {}) as Record<string, unknown>).filter(
|
||||||
|
([k]) => Object.prototype.hasOwnProperty.call(DEFAULTS, k),
|
||||||
|
);
|
||||||
|
```
|
||||||
|
|
||||||
|
Apply the identical change in `web/src/app/api/discover/config/route.ts`.
|
||||||
|
|
||||||
|
- [ ] **Step 4: Add the mirror test for discover PATCH**
|
||||||
|
|
||||||
|
Append the same test (with a `patchReq` pointing at `/api/discover/config` and importing this route's `PATCH`) to `web/src/app/api/discover/config/route.test.ts`.
|
||||||
|
|
||||||
|
- [ ] **Step 5: Add the `constructor` case to the DELETE allowlist test**
|
||||||
|
|
||||||
|
In `web/src/app/api/config/route.test.ts`, the test at line 85 ("rejects prototype-chain field names") only exercises `__proto__`. Add `constructor` alongside it:
|
||||||
|
|
||||||
|
```ts
|
||||||
|
for (const bad of ["__proto__", "constructor"]) {
|
||||||
|
const res = await DELETE(delReq(bad));
|
||||||
|
expect(res.status).toBe(400);
|
||||||
|
}
|
||||||
|
// Must not have collapsed to deleteMany({ where: {} }) and wiped the table.
|
||||||
|
expect(await prisma.config.count()).toBe(before);
|
||||||
|
expect(await prisma.config.findUnique({ where: { key: "qobuz.password" } })).not.toBeNull();
|
||||||
|
```
|
||||||
|
|
||||||
|
(Replace the existing single `__proto__` DELETE block; keep the surrounding `before`/PUT setup.)
|
||||||
|
|
||||||
|
- [ ] **Step 6: Run all three affected test files to verify they pass**
|
||||||
|
|
||||||
|
Run: `cd web && npx vitest run src/app/api/monitor/config/route.test.ts src/app/api/discover/config/route.test.ts src/app/api/config/route.test.ts`
|
||||||
|
Expected: PASS.
|
||||||
|
|
||||||
|
- [ ] **Step 7: Commit**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git add web/src/app/api/monitor/config/route.ts web/src/app/api/discover/config/route.ts \
|
||||||
|

## Task 2: Tier A2 — Monitor toggle aria-label + Settings eyebrow copy
|
||||||
|
|
||||||
|
**Files:**
|
||||||
|
- Modify: `web/src/app/settings/settings-form.tsx:159` (eyebrow) and `:273-277` (toggle)
|
||||||
|
|
||||||
|
**Interfaces:**
|
||||||
|
- Consumes: nothing.
|
||||||
|
- Produces: nothing.
|
||||||
|
|
||||||
|
No unit test (node vitest env can't render this component; verified by build + Playwright later).
|
||||||
|
|
||||||
|
- [ ] **Step 1: Add an aria-label to the Monitor enable checkbox**
|
||||||
|
|
||||||
|
At `web/src/app/settings/settings-form.tsx:273`, add `aria-label` to the `<input type="checkbox">` inside the Monitor `<label className="toggle">`:
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
<input
|
||||||
|
type="checkbox"
|
||||||
|
aria-label="automatic monitoring"
|
||||||
|
checked={monitorCfg["monitor.enabled"] === "true"}
|
||||||
|
onChange={(e) => setMon("monitor.enabled", e.target.checked ? "true" : "false")}
|
||||||
|
/>
|
||||||
|
```
|
||||||
|
|
||||||
|
- [ ] **Step 2: Fix the Settings eyebrow copy**
|
||||||
|
|
||||||
|
At `web/src/app/settings/settings-form.tsx:159`, the eyebrow lists only three of the five tabs. Update it:
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
<PageHead title="Settings" eyebrow="Credentials · library · monitor · discovery" />
|
||||||
|
```
|
||||||
|
|
||||||
|
- [ ] **Step 3: Typecheck + build to confirm no breakage**
|
||||||
|
|
||||||
|
Run: `cd web && npx tsc --noEmit && npm run build`
|
||||||
|
Expected: clean (no type errors, build succeeds).
|
||||||
|
|
||||||
|
- [ ] **Step 4: Commit**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git add web/src/app/settings/settings-form.tsx
|
||||||
|
git commit -m "fix(web): label Monitor toggle for a11y + correct Settings eyebrow"
|
||||||
|
```

## Task 3: Migration — add DiscoverySeedContribution + ScanWorkItem tables
|
||||||
|
|
||||||
|
**Files:**
|
||||||
|
- Modify: `web/prisma/schema.prisma`
|
||||||
|
- Create: `web/prisma/migrations/<timestamp>_add_contributions_and_scan_worklist/migration.sql`
|
||||||
|
- Modify: `worker/tests/conftest.py` (clean the new tables)
|
||||||
|
|
||||||
|
**Interfaces:**
|
||||||
|
- Produces (raw SQL tables consumed by Tasks 4 & 5):
|
||||||
|
- `DiscoverySeedContribution(id, "candidateMbid", "candidateName", "seedMbid", score float8, sources text[], "updatedAt")`, `UNIQUE("candidateMbid","seedMbid")`.
|
||||||
|
- `ScanWorkItem(id, "scanId", artist, album, path, done bool)`, `UNIQUE("scanId", path)`.
|
||||||
|
|
||||||
|
- [ ] **Step 1: Add both models to `web/prisma/schema.prisma`**
|
||||||
|
|
||||||
|
Append after the `DiscoverySuggestion` model:
|
||||||
|
|
||||||
|
```prisma
|
||||||
|
model DiscoverySeedContribution {
|
||||||
|
id String @id @default(cuid())
|
||||||
|

|
||||||
|
candidateName String
|
||||||
|
seedMbid String
|
||||||
|
score Float
|
||||||
|
sources String[]
|
||||||
|
updatedAt DateTime @updatedAt
|
||||||
|
|
||||||
|

||||||
|
|
||||||

|
||||||
|

|
||||||
|
scanId String
|
||||||
|
artist String
|
||||||
|
album String
|
||||||
|
path String
|
||||||
|
done Boolean @default(false)
|
||||||
|
|
||||||
|
@@unique([scanId, path])
|
||||||
|
@@index([scanId, done, artist, album])
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
- [ ] **Step 2: Hand-author the migration SQL**
|
||||||
|
|
||||||
|
Create `web/prisma/migrations/20260713120000_add_contributions_and_scan_worklist/migration.sql` (use a timestamp lexicographically after `20260711215631`):
|
||||||
|
|
||||||
|
```sql
|
||||||
|
-- CreateTable
|
||||||
|
CREATE TABLE "DiscoverySeedContribution" (
|
||||||
|
"id" TEXT NOT NULL,
|
||||||
|
"candidateMbid" TEXT NOT NULL,
|
||||||
|
"candidateName" TEXT NOT NULL,
|
||||||
|
"seedMbid" TEXT NOT NULL,
|
||||||
|
"score" DOUBLE PRECISION NOT NULL,
|
||||||
|
"sources" TEXT[],
|
||||||
|
"updatedAt" TIMESTAMP(3) NOT NULL,
|
||||||
|
|
||||||
|
CONSTRAINT "DiscoverySeedContribution_pkey" PRIMARY KEY ("id")
|
||||||
|
);
|
||||||
|
|
||||||
|
-- CreateTable
|
||||||
|
CREATE TABLE "ScanWorkItem" (
|
||||||
|
"id" TEXT NOT NULL,
|
||||||
|
"scanId" TEXT NOT NULL,
|
||||||
|
"artist" TEXT NOT NULL,
|
||||||
|
"album" TEXT NOT NULL,
|
||||||
|
"path" TEXT NOT NULL,
|
||||||
|
"done" BOOLEAN NOT NULL DEFAULT false,
|
||||||
|
|
||||||
|
CONSTRAINT "ScanWorkItem_pkey" PRIMARY KEY ("id")
|
||||||
|
);
|
||||||
|
|
||||||
|
-- CreateIndex
|
||||||
|
CREATE UNIQUE INDEX "DiscoverySeedContribution_candidateMbid_seedMbid_key" ON "DiscoverySeedContribution"("candidateMbid", "seedMbid");
|
||||||
|
CREATE INDEX "DiscoverySeedContribution_candidateMbid_idx" ON "DiscoverySeedContribution"("candidateMbid");
|
||||||
|
CREATE INDEX "DiscoverySeedContribution_seedMbid_idx" ON "DiscoverySeedContribution"("seedMbid");
|
||||||
|
|
||||||
|
-- CreateIndex
|
||||||
|
CREATE UNIQUE INDEX "ScanWorkItem_scanId_path_key" ON "ScanWorkItem"("scanId", "path");
|
||||||
|
CREATE INDEX "ScanWorkItem_scanId_done_artist_album_idx" ON "ScanWorkItem"("scanId", "done", "artist", "album");
|
||||||
|
```
|
||||||
|
|
||||||
|
- [ ] **Step 3: Regenerate the Prisma client and apply to lyra_test**
|
||||||
|
|
||||||
|
Run:
|
||||||
|
```bash
|
||||||
|
cd web && npx prisma generate
|
||||||
|
DATABASE_URL=postgresql://lyra:lyra@localhost:5432/lyra_test npx prisma migrate deploy
|
||||||
|
```
|
||||||
|
Expected: `prisma generate` succeeds; `migrate deploy` reports the new migration applied (8 migrations). Confirm `npx prisma migrate status` (against lyra_test) shows "Database schema is up to date".
|
||||||
|
|
||||||
|
- [ ] **Step 4: Clean the new tables in the worker test fixture**
|
||||||
|
|
||||||
|
In `worker/tests/conftest.py`, the `conn` fixture DELETEs a set of tables both before (setup) and after (teardown). Add the two new tables to **both** DELETE blocks, before the `Config` delete in each:
|
||||||
|
|
||||||
|
```python
|
||||||
|
cur.execute('DELETE FROM "DiscoverySeedContribution"')
|
||||||
|
cur.execute('DELETE FROM "ScanWorkItem"')
|
||||||
|
```
|
||||||
|
|
||||||
|
- [ ] **Step 5: Verify the tables exist and the suite still boots**
|
||||||
|
|
||||||
|
Run: `cd worker && python -m pytest tests/test_discovery_schema.py -q`
|
||||||
|
Expected: PASS (existing schema tests unaffected; the new tables are reachable). If it errors on a missing table, re-check Step 3 applied to `lyra_test`.
|
||||||
|
|
||||||
|
- [ ] **Step 6: Commit**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git add web/prisma/schema.prisma web/prisma/migrations worker/tests/conftest.py
|
||||||
|
git commit -m "feat: add DiscoverySeedContribution + ScanWorkItem tables"
|
||||||
|
```
|
||||||
|
|

||||||
|
## Task 4: Tier B1 — per-seed discovery contributions + recompute
|
||||||
|
|
||||||
|
**Files:**
|
||||||
|
- Modify: `worker/lyra_worker/discovery.py` (`run_discovery` and helpers)
|
||||||
|
- Test: `worker/tests/test_discovery.py` (add new tests)
|
||||||
|
|
||||||
|
**Interfaces:**
|
||||||
|
- Consumes: `DiscoverySeedContribution` table (Task 3); `_upsert_artist`, `_derive_albums`, `_healthy_sources`, `_seed_artists`, `_followed_mbids` (existing, unchanged signatures).
|
||||||
|
- Produces: `run_discovery(conn, sources, browser, cfg) -> DiscoveryResult` (same signature); score is now sum-of-all-seed-contributions.
|
||||||
|
|
||||||
|
**Design:** Replace the in-memory chunk-local aggregation with contribution rows. Per swept seed, replace its rows; then recompute every affected candidate's suggestion from the summed contributions.
|
||||||
|
|
||||||
|
- [ ] **Step 1: Write the failing test — score sums across separate chunks**
|
||||||
|
|
||||||
|
Add to `worker/tests/test_discovery.py`:
|
||||||
|
|
||||||
|
```python
|
||||||
|
def _artist_score(conn, mbid):
|
||||||
|
with conn.cursor() as cur:
|
||||||
|
cur.execute('SELECT score, "seedCount" FROM "DiscoverySuggestion" WHERE "artistMbid" = %s', (mbid,))
|
||||||
|
return cur.fetchone()
|
||||||
|
|
||||||
|
def test_score_sums_across_separate_chunks(conn):
|
||||||
|
# Two seeds, both eligible, forced into separate one-seed chunks by chunk_size=1.
|
||||||
|
insert_watched_artist(conn, mbid="s1", name="Seed One",
|
||||||
|
last_discovered_sql="now() - interval '200 hours'")
|
||||||
|
insert_watched_artist(conn, mbid="s2", name="Seed Two",
|
||||||
|
last_discovered_sql="now() - interval '190 hours'")
|
||||||
|
src = FakeSimilaritySource(similar={
|
||||||
|
"s1": [SimilarArtist("c1", "Shared", 0.6)],
|
||||||
|
"s2": [SimilarArtist("c1", "Shared", 0.5)],
|
||||||
|
})
|
||||||
|
cfg = DiscoveryConfig(chunk_size=1)
|
||||||
|
run_discovery(conn, [src], FakeMbBrowser(), cfg) # processes s1 (older)
|
||||||
|
run_discovery(conn, [src], FakeMbBrowser(), cfg) # processes s2
|
||||||
|
# replace-not-accumulate would leave 0.5/seedCount1; contributions give the sum.
|
||||||
|
assert _artist_score(conn, "c1") == (1.1, 2)
|
||||||
|
```
|
||||||
|
|
||||||
|
- [ ] **Step 2: Run it to verify it fails**
|
||||||
|
|
||||||
|
Run: `cd worker && python -m pytest tests/test_discovery.py::test_score_sums_across_separate_chunks -q`
|
||||||
|
Expected: FAIL — score is `0.5`, seedCount `1` (last chunk overwrote via `score = EXCLUDED.score`).
|
||||||
|
|
||||||
|
- [ ] **Step 3: Rewrite the aggregation in `discovery.py`**
|
||||||
|
|
||||||
|
Replace the body of `run_discovery` (lines ~146-194) and add two helpers. Keep `_upsert_artist`, `_upsert_album`, `_derive_albums`, `_existing_rg_mbids`, `_healthy_sources`, `_seed_artists`, `_followed_mbids` as-is.
|
||||||
|
|
||||||
|
```python
|

## Task 5: Tier B2 — persisted scan worklist
|
||||||
|
|
||||||
|
**Files:**
|
||||||
|
- Modify: `worker/lyra_worker/scan.py`
|
||||||
|
- Modify: `worker/lyra_worker/main.py` (`maybe_run_scan`, imports)
|
||||||
|
- Test: `worker/tests/test_scan_chunk.py` (rewrite to the worklist API)
|
||||||
|
|
||||||
|
**Interfaces:**
|
||||||
|
- Consumes: `ScanWorkItem` table (Task 3); existing `_iter_album_entries`, `_process_album`, `ScanResult`.
|
||||||
|
- Produces:
|
||||||
|
- `build_worklist(conn, scan_id: str, dest_root: str = "/music") -> int`
|
||||||
|
- `scan_chunk(conn, resolver, probe, browser, scan_id: str, limit: int) -> tuple[int, int, bool]` — returns `(imported, skipped, done)`.
|
||||||
|
- `clear_worklist(conn, scan_id: str) -> None`
|
||||||
|
- `scan_library(conn, resolver, probe, browser, dest_root="/music") -> ScanResult` — unchanged signature, reimplemented on the worklist.
|
||||||
|
|
||||||
|
**Note:** `scan_chunk`'s signature CHANGES (drops `dest_root`/`cursor`, adds `scan_id`, drops the returned cursor). `test_scan.py` uses only `scan_library` and is unaffected; `test_scan_trigger.py` checks `scan.progress`/`scan.result`/`scan.inProgress` (not `scan.cursor`) and is unaffected; only `test_scan_chunk.py` must be rewritten.

|

|
|

|
Run: `cd worker && python -m pytest tests/test_scan_chunk.py tests/test_scan.py -q`
|
||||||
|
Expected: PASS (test_scan.py uses `scan_library`, unchanged behavior; test_scan_chunk.py exercises the new API).
|
||||||
|
|
||||||
|
- [ ] **Step 5: Rewire `maybe_run_scan` in `main.py`**
|
||||||
|
|

Update the import at `worker/lyra_worker/main.py:17`:
|
||||||
|
|

|
```python

||||||
|
from lyra_worker.scan import build_worklist, clear_worklist, scan_chunk
|
||||||
|
```
|
||||||
|
|
||||||

Add `import uuid` near the top imports. Replace `maybe_run_scan` (lines ~58-96) with:
|
||||||
|
|
||||||
|
```python
|
||||||
|
def maybe_run_scan(conn, resolver, probe, browser, config, dest_root: str = DEST_ROOT) -> None:

||||||
|

|
_set_config(conn, "scan.progress", "")
|
||||||
|
_set_config(conn, "scan.inProgress", "false")
|

|
clear_worklist(conn, scan_id)
|
||||||
|
_set_config(conn, "scan.id", "")
|
||||||
|
print(f"worker: library scan done — {imported_total} imported, {skipped_total} skipped", flush=True)
|
||||||
|
else:
|
||||||
|
_set_config(conn, "scan.progress", f"{imported_total}/{skipped_total}")
|
||||||
|
```
|
||||||
|
|
||||||
|
- [ ] **Step 6: Run the scan trigger tests + the full worker suite**
|
||||||
|
|
||||||
|
Run: `cd worker && python -m pytest tests/test_scan_trigger.py -q && python -m pytest -q`
|
||||||
|
Expected: PASS. `test_scan_trigger.py` is unchanged (it asserts on `scan.progress`/`scan.result`/`scan.inProgress`, all preserved). Full suite green (previous baseline 173 passed / 7 skipped, now higher with the added tests).
|
||||||
|
|
||||||
|
- [ ] **Step 7: Commit**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git add worker/lyra_worker/scan.py worker/lyra_worker/main.py worker/tests/test_scan_chunk.py
|
||||||
|
git commit -m "feat(worker): persisted scan worklist (O(N) scan, robust to mid-scan changes)"

||||||

## Final verification (before merge)
|
||||||
|
|
||||||
|
- [ ] **Worker suite:** `cd worker && python -m pytest -q` → all green.
|
||||||
|
- [ ] **Web suite:** `cd web && npx vitest run` → all green.
|
||||||
|
- [ ] **Typecheck + build:** `cd web && npx tsc --noEmit && npm run build` → clean.
|
||||||
|
- [ ] **Migration status (lyra_test):** `cd web && DATABASE_URL=postgresql://lyra:lyra@localhost:5432/lyra_test npx prisma migrate status` → up to date, 8 migrations.
|
||||||
|
- [ ] Opus whole-branch review (via subagent-driven-development's final review), then ff-merge `cleanup/tier-a-b` → `main`, push, `docker compose up -d --build web worker`, verify live (web 200, worker healthy, `migrate deploy` reports the new migration applied).

## Self-review notes
|
||||||
|
|
||||||
|
- **Spec coverage:** Tier A1 (Task 1), A2 (Task 2), A3 (Task 1 Step 5); Tier B1 (Tasks 3+4); Tier B2 (Tasks 3+5); migration (Task 3); testing + delivery (Final verification). All spec sections mapped.
|
||||||
|
- **Type consistency:** `scan_chunk` new signature `(conn, resolver, probe, browser, scan_id, limit) -> (imported, skipped, done)` used identically in `scan.py`, `main.py`, and `test_scan_chunk.py`. `build_worklist`/`clear_worklist` signatures match across producer and callers. Discovery `run_discovery` signature unchanged; helpers `_record_contributions`/`_recompute_suggestions` are internal.
|
||||||
|
- **Backward-compat:** existing `test_aggregates_scores_across_seeds`, `test_scan.py`, `test_scan_trigger.py` pass unchanged by design (verified against their current assertions).
