Database/Schema Alignment ### Status: N/A *N/A because the session introduced no DB-layer changes, migrations, persisted database schema, seed data, indexes, constraints, or generated database types.* ### Issues Found N/A - no DB-layer changes. *** ## 6. Success Criteria From `spec.md`: ### Functional Requirements * [x] A configured source with a private last-good baseline and zero current accepted evidence produces a source-death warning. * [x] A first run with zero accepted evidence does not produce a source-death warning. * [x] Disabled, unconfigured, credential-missing, restricted, placeholder, and skipped fallback sources do not produce source-death warnings. * [x] Sources with current accepted evidence update the private last-good baseline. * [x] Collection health, Sources, and Engine Replay show safe source-death warning labels. * [x] Browser payloads expose no private baseline path, cache path, file name, prior accepted-evidence count, raw diagnostic payload, stack trace, prompt, provider response, token, or credential-shaped string. ### Testing Requirements * [x] Unit tests written and passing for baseline read/write, eligibility, zeroed-live alarm, first-run no-op, disabled no-op, corrupt baseline fallback, and privacy-safe formatting. * [x] Collector tests prove alarm integration, safe warning propagation, baseline update behavior, and no warnings for ineligible sources. * [x] Schema/view-model tests prove legacy default parsing and browser-safe warning labels. * [x] Engine Replay and Sources component tests prove warning visibility without private strings or layout instability. * [x] Payload-size and private-artifact checks remain green. ### Non-Functional Requirements * [x] Browser payload stays under the 1 MB extension budget. * [x] The private baseline helper is deterministic, bounded, and linear in source count. * [x] Private baseline writes use safe path segments and atomic write behavior. * [x] No new source, media, credential flow, database, hosted storage, dependency, or third-party transfer is introduced. ### Quality Gates * [x] All files ASCII-encoded. * [x] Unix LF line endings. * [x] Code follows project conventions. * [x] New enum or schema branches use explicit fallback behavior. *** ## 7. Conventions Compliance ### Status: PASS | Category | Status | Notes | | -------------- | ------ | ------------------------------------------------------------------------------------------------------- | | Naming | PASS | Source-death helper, schema, and view-model names are descriptive and align with Trend Finder language. | | File Structure | PASS | Script helper/tests, app schemas, view models, components, and docs stay in established directories. | | Error Handling | PASS | Missing/corrupt baseline and write failures degrade to safe warnings without exposing private paths. | | Comments | PASS | No obvious commented-out code or noisy explanatory comments added. | | Testing | PASS | Focused unit, collector, trace, view-model, Sources, and Engine Replay tests were added near behavior. | ### Convention Violations None. ### Format Note The repo-wide `bun run format:check` reports existing `.spec_system` markdown formatting warnings outside this session. Session-touched files checked with targeted Prettier pass after scoped formatting. *** ## 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/source-death-baseline.ts` * `scripts/extensions/trend-finder/collector.ts` * `scripts/extensions/trend-finder/engine-trace.ts` * `src/extensions/trend-finder/schema.ts` * `src/extensions/trend-finder/view-model.ts` | Category | Status | File | Details | | ------------------ | ------ | ----------------------------------------------- | -------------------------------------------------------------------------------------------- | | Trust boundaries | PASS | `source-death-baseline.ts`, `engine-trace.ts` | External/private baseline input is parsed with Zod and browser trace output is sanitized. | | Resource cleanup | PASS | `source-death-baseline.ts` | Atomic write failure removes the temp path and tests cover cleanup. | | Mutation safety | PASS | `collector.ts` | Alarm evaluation is derived once at the source boundary before trace/browser handoff. | | Failure paths | PASS | `source-death-baseline.ts` | Missing/corrupt baseline and write failure return safe warnings and do not block collection. | | Contract alignment | PASS | `schema.ts`, `view-model.ts`, `engine-trace.ts` | Browser and trace schemas have defaulted fields and tests cover legacy parsing. | ### Violations Found None. ### Fixes Applied During Validation * Removed an unused catch parameter in `scripts/extensions/trend-finder/source-death-baseline.ts`. * Ran scoped Prettier formatting on `scripts/extensions/trend-finder/engine-trace.ts` and the session spec. ## Validation Result ### PASS Session 09 meets the implementation, testing, privacy, payload, and quality requirements for the private source-death baseline alarm. ### Required Actions None. ## Next Steps Run `updateprd` to mark the session complete. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase29-session09-source-death-baseline-alarm/validation.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
