No new product behavior, endpoint, data schema, dependency, or external transfer path is intended in this session. *** ## Review Matrix | Area | Security Claim | Evidence | Status | | -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------ | | Read bridge | `/__graphify_list` and `/__graphify_graph` are loopback-only and path-confined | Source audit complete; focused tests cover loopback rejection, method rejection, invalid id, path escape, no-store/nosniff headers, stream failure, seed fallback headers, registry validation, and stale-entry prune | PASS | | Admin writes | `/__graphify_admin_status`, `/__graphify_ingest`, and `/__graphify_remove` require loopback, same-run token, admin env, non-demo state, and non-production mode | Source audit complete; focused tests cover disabled admin, remote rejection, invalid token, wrong method, bad JSON, unsupported media type, body limit, unsafe Git URL, missing source path, invalid remove id, and client demo/offline/token-missing gates | PASS | | Process spawn | External `graphify` calls use argv-only spawn and bounded cleanup | Source audit complete; tests assert graphify receives `["update", sourceDir]`, Git receives `["clone", "--depth", "1", ...]`, temp clone cleanup runs, and local `graphify-out` cleanup runs after failures and success | PASS | | Path confinement | Local paths, registry graph paths, temp clones, and graph ids are constrained before file access | Source audit complete; tests cover graph path escape, private path non-leakage, confined remove, and idempotent missing remove | PASS | | Oversized graphs | Vendored-dependency and node-count guards reject risky graph payloads | Source audit complete; tests cover `graph_too_large`; source audit confirms vendored-dependency guard | PASS | | Token redaction | Dashboard tokens, OAuth material, and auth headers are not logged or documented | Source audit complete; focused token tests cover malformed/failure states without exposing token material; private-artifact scan passed | PASS | | Third-party transfer | Optional `graphify` AST extraction remains local; no new third-party data transfer is introduced by this session | Global security posture and docs now state graphify is optional/local and no hosted ingest or new third-party transfer path was added | PASS | | GDPR | No new personal data export behavior is introduced; local graph registry/metadata has a deletion path | Global inventory now includes local Knowledge Graph registry/metadata with local storage, self-use basis, retention, and deletion path | PASS | *** ## Validation Evidence | Check | Status | Notes | | ---------------------- | ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Source security audit | PASS | Read bridge, admin bridge, hooks, token hook, docs, and global security posture reviewed | | Focused security tests | PASS | `bun run test -- scripts/lib/__tests__/knowledge-graph-dev-bridge.test.ts scripts/lib/__tests__/knowledge-graph-admin-bridge.test.ts src/hooks/__tests__/use-knowledge-graph-admin.test.tsx src/hooks/__tests__/use-knowledge-graph-token.test.tsx` passed: 4 files, 23 tests | | Full test suite | PASS | `bun run test` passed after closeout fixes: 267 files, 3305 tests | | Typecheck and lint | PASS | `bun run typecheck`, `bun run typecheck:scripts`, `bun run lint`, and `bun run format:check` passed; lint reports existing fast-refresh warnings only | | Private artifact scan | PASS | `bun run runtime:check-private` passed after build; ignored Playwright artifacts from failed drafts were removed | | ASCII and LF scan | PASS | Changed and untracked files passed ASCII, LF, and trailing-whitespace checks | *** ## Findings No open findings. *** ## Residual Risk Residual risk is low and local-only. * Live destructive ingest/remove against operator data was not run by default. Future live write smoke checks should remain opt-in and use disposable sources. * `graphify` remains optional. Missing binary states are expected and do not block seed/demo fallback. * Graph JSON files can contain local project structure. Operators should remove entries through `/knowledge-graph` or delete graph files directly when a graph should no longer be retained. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

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/phase26-session09-documentation-validation-release/security-compliance.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.
