Deliverables Verification ### Status: PASS #### Files Created | File | Found | Status | | --------------------------------------------------------------------------- | ----- | ------ | | `scripts/extensions/trend-finder/sources/signal-identity.ts` | Yes | PASS | | `scripts/extensions/trend-finder/sources/__tests__/signal-identity.test.ts` | Yes | PASS | | `scripts/extensions/trend-finder/collector.ts` | Yes | PASS | | `scripts/lib/ai-runtime/trend-analyst.ts` | Yes | PASS | | `scripts/lib/ai-runtime/scoring.ts` | Yes | PASS | | `src/extensions/trend-finder/schema.ts` | Yes | PASS | | `src/extensions/trend-finder/engine-trace.ts` | Yes | PASS | | `scripts/extensions/trend-finder/engine-trace.ts` | Yes | PASS | | `scripts/extensions/trend-finder/__tests__/collector.test.ts` | Yes | PASS | | `scripts/lib/ai-runtime/__tests__/scoring.test.ts` | Yes | PASS | | `src/extensions/trend-finder/__tests__/view-model.test.ts` | Yes | PASS | | `scripts/extensions/trend-finder/__tests__/engine-trace.test.ts` | Yes | PASS | ### Missing Deliverables None. *** ## 3. ASCII Encoding Check ### Status: PASS | File | Encoding | Line Endings | Status | | --------------------------------------------------------------------------- | -------- | ------------ | ------ | | `scripts/extensions/trend-finder/sources/signal-identity.ts` | ASCII | LF | PASS | | `scripts/extensions/trend-finder/sources/__tests__/signal-identity.test.ts` | ASCII | LF | PASS | | `scripts/extensions/trend-finder/collector.ts` | ASCII | LF | PASS | | `scripts/lib/ai-runtime/trend-analyst.ts` | ASCII | LF | PASS | | `scripts/lib/ai-runtime/scoring.ts` | ASCII | LF | PASS | | `src/extensions/trend-finder/schema.ts` | ASCII | LF | PASS | | `src/extensions/trend-finder/engine-trace.ts` | ASCII | LF | PASS | | `scripts/extensions/trend-finder/engine-trace.ts` | ASCII | LF | PASS | | `scripts/extensions/trend-finder/__tests__/collector.test.ts` | ASCII | LF | PASS | | `scripts/lib/ai-runtime/__tests__/scoring.test.ts` | ASCII | LF | PASS | | `src/extensions/trend-finder/__tests__/view-model.test.ts` | ASCII | LF | PASS | | `scripts/extensions/trend-finder/__tests__/engine-trace.test.ts` | ASCII | LF | PASS | ### Encoding Issues None. *** ## 4. Test Results ### Status: PASS | Metric | Value | | ----------- | ------------- | | Total Tests | 3481 | | Passed | 3481 | | Failed | 0 | | Coverage | Not collected | ### Commands Run * `bun run test` - passed (283 files, 3481 tests). * `bun run typecheck` - passed. * `bun run typecheck:scripts` - passed. * `bun run lint` - passed. * `bunx prettier --check [session deliverables and artifacts]` - passed after formatting session markdown artifacts. * `git diff --check` - passed. * `git diff -- package.json bun.lock` - no dependency changes. ### Failed Tests None. *** ## 5. Database/Schema Alignment ### Status: N/A *N/A because the session introduced no DB-layer changes, migrations, seeds, indexes, or persisted storage shape.* * [x] Matching schema artifact exists for each relevant DB-layer change: N/A. * [x] Code and schema artifacts are aligned: N/A. * [x] Migration/status/diff check passed locally: N/A. * [x] Seed or rollback updates included when conventions require them: N/A. ### Issues Found N/A - no DB-layer changes. The touched `src/extensions/trend-finder/schema.ts` file is a Zod browser payload schema, not a database schema artifact. *** ## 6. Success Criteria From `spec.md`: ### Functional Requirements * [x] URL normalization strips tracking parameters, lowercases hosts, removes `www.`, sorts retained query parameters, and handles malformed URLs deterministically. * [x] Same-source fingerprint repeats are dropped before analyst input and counted by source. * [x] Cross-source content-hash siblings are retained as evidence rows but grouped for scoring. * [x] A story syndicated across three sources counts once for evidence volume, momentum, and diversity-sensitive scoring while preserving source breakdown coverage. * [x] Browser-visible payload fields expose bounded counts only and never expose raw normalized URLs, private paths, or source input payloads. ### Testing Requirements * [x] Unit tests written and passing for identity helpers. * [x] Collector tests cover duplicate warnings, high-rate warnings, and browser-safe metadata. * [x] Scoring tests prove syndicated evidence does not inflate volume, momentum, or diversity-sensitive scoring. * [x] Schema and engine-trace tests prove legacy payloads parse and counters are sanitized. * [x] Manual verification notes recorded for the fixture replay and browser-safe trace boundaries. ### Quality Gates * [x] All files ASCII-encoded. * [x] Unix LF line endings. * [x] Code follows project conventions. * [x] Focused Vitest suites pass. * [x] Full Vitest suite passes. *** ## 7. Conventions Compliance ### Status: PASS | Category | Status | Notes | | -------------- | ------ | -------------------------------------------------------------------------------------------------- | | Naming | PASS | New helper and metadata names are descriptive and Trend Finder scoped. | | File Structure | PASS | Source helpers and script tests live under existing Trend Finder script directories. | | Error Handling | PASS | Malformed URLs are handled deterministically without throwing in collection. | | Comments | PASS | No obvious commented-out code or noisy comments found in spot-check. | | Testing | PASS | Tests are close to the behavior they cover and assert behavior rather than implementation details. | ### Convention Violations None. *** ## 8. Security & GDPR Compliance ### Status: PASS **Full report**: See `security-compliance.md` in this session directory. #### Summary | Area | Status | Findings | | -------- | ------ | -------- | | Security | PASS | 0 issues | | GDPR | N/A | 0 issues | ### Critical Violations None. *** ## 9. Behavioral Quality Spot-Check ### Status: PASS **Checklist applied**: Yes **Files spot-checked**: * `scripts/extensions/trend-finder/sources/signal-identity.ts` * `scripts/extensions/trend-finder/collector.ts` * `scripts/lib/ai-runtime/scoring.ts` * `src/extensions/trend-finder/schema.ts` * `scripts/extensions/trend-finder/engine-trace.ts` | Category | Status | File | Details | | ------------------ | ------ | --------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------- | | Trust boundaries | PASS | `collector.ts`, `engine-trace.ts` | Browser and replay payloads receive sanitized aggregate counters only. | | Resource cleanup | PASS | `signal-identity.ts` | Pure helper has no timers, subscriptions, connections, or persistent resources. | | Mutation safety | PASS | `collector.ts` | Deduplication state is local to each collection pass and does not persist across runs. | | Failure paths | PASS | `signal-identity.ts`, `collector.ts` | Malformed URLs fall back deterministically; high duplicate rates emit warnings and trace events. | | Contract alignment | PASS | `scoring.ts`, `schema.ts`, `trend-analyst.ts` | Legacy defaults preserve parsing, full evidence remains visible, and grouped projection is limited to scoring-sensitive inputs. | ### Violations Found None. ### Fixes Applied During Validation * Formatted `.spec_system/specs/phase28-session01-cross-source-signal-identity-and-dedup/spec.md`, `tasks.md`, and `implementation-notes.md` after scoped Prettier check flagged markdown formatting. ## Validation Result ### PASS Session `phase28-session01-cross-source-signal-identity-and-dedup` satisfies the validate workflow requirements. All tasks are complete, deliverables exist, encoding and line endings are clean, full tests pass, no DB-layer alignment work is applicable, security passes, GDPR is not applicable, and behavioral spot-checks found no blocking issues. ### Required Actions None. ## Next Steps Run `updateprd` to mark the session complete. --- # Agent Instructions This documentation is published with GitBook.
