+## Production readiness and evidence
 
-Current release-candidate work is evidence-gated. The supported default is local loopback (`127.0.0.1`) with user-configured model credentials. Binding to public interfaces requires explicit host, trusted CORS origins, authentication, and network controls outside CodeRAG's defaults.
+CodeRAG is complete for the portfolio/local-product scope: a verified codebase context engine with CLI, REST, MCP, and local web UI surfaces. Current evidence covers a real local MarkupSafe indexing/query flow with generated answers, grounded citations, context packs, API, MCP, CLI, UI screenshots, and negative cases.
 
-- Cloud LLM providers send prompt context to the selected provider. Use local/private profiles only when configured and verified for your environment.
+What is claimed:
+
+- Local loopback operation (`127.0.0.1`) with user-configured model credentials.
+- Durable SQLite repository/job state, hybrid retrieval, graph-backed code intelligence where supported, and deterministic citation verification against indexed snapshots.
+- Safe default posture: trusted CORS is required for non-local browser origins, remote model code is disabled unless explicitly configured, and retrieval-only workflows can run without an LLM key.
 - Unsupported graph languages degrade explicitly to text/chunk retrieval; they do not report fake graph confidence.
-- CodeRAG verifies citations against retrieved chunks, but it does not prove repository correctness, execute arbitrary project tests, or make autonomous code changes.
 
-Release-candidate evidence is committed in `docs/superpowers/plans/2026-06-30-m7-release-run-record.md`, `evals/runs/20260630-m7-production-rc.json`, and `evals/reports/20260630-m7-production-rc.md`.
+What is not claimed:
+
+- Hosted SaaS or multi-user production deployment readiness.
+- That CodeRAG proves repository correctness, executes arbitrary project tests, or makes autonomous code changes.
+- Physical headed-browser proof in every harness. The latest local UI E2E captured DOM/screenshot evidence; if a visible browser is required, run the same frozen plan with a headed Playwright-capable driver.
+
+Evidence:
+
+- Portfolio completion plan: `docs/superpowers/plans/2026-07-02-coderag-portfolio-complete.md`
+- Real local E2E plan and run record: `docs/superpowers/plans/2026-07-02-coderag-portfolio-e2e-plan.md`, `docs/superpowers/plans/2026-07-02-coderag-portfolio-e2e-run-record.md`

+# CodeRAG Portfolio Complete 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:** Make CodeRAG honestly complete as a local/portfolio-grade verified codebase context engine, without claiming hosted SaaS or multi-user production readiness.
+
+**Architecture:** Tighten correctness at the source first: snapshot-backed citation verification, transparent fallback semantics, shared service seams, then interface parity and evidence. Release readiness is evidence-gated: no “complete” claim until CLI/API/MCP/UI flows pass real E2E records and EvalFly covers behavior, not only file-existence pointers.
+
+**Tech Stack:** Python 3.11+, FastAPI, Gradio, SQLite registry, ChromaDB, deterministic pytest, EvalFly smoke/regression config, MCP streamable HTTP/stdio adapters.
+
+## Global Constraints
+
+- Do not expose or log provider API keys.
+- Preserve loopback-safe server defaults and non-wildcard credentialed CORS defaults.
+- Preserve `retrieval-only` as a no-key mode.
+- `grounded=True` must mean citations were verified against indexed evidence, not merely emitted by the model.
+- Browser-visible UI E2E is required if the UI remains a supported surface.
+- Production SaaS claims are out of scope: no auth, multi-tenant hosting, billing, rate-limit, or SRE claim.
+- Use TDD for behavior changes: failing test first, minimal implementation, focused verification.
+- Subagents must not run project-wide gates; final verification is done by Main.
+
+---
+
+## File Structure
+
+- `src/coderag/generation/citations.py`: citation parser/verifier and snapshot-aware verification result semantics.
+- `src/coderag/generation/generator.py`: model generation plus transparent verified-evidence fallback.
+- `src/coderag/models/document.py`: indexed document metadata including content hashes.
+- `src/coderag/models/response.py`: response schema fields for fallback/original answer/invalid citations if needed by adapters.
+- `src/coderag/services/registry.py`: SQLite file/chunk metadata persistence and lookup APIs used by verifier/evidence.
+- `src/coderag/services/indexing.py`: compute and persist file/chunk hashes during full/incremental index.
+- `src/coderag/services/retrieval.py`: canonical retrieval/generation orchestration and no-context/error behavior.
+- `src/coderag/ui/handlers.py`: thin UI adapter over shared services; no duplicate indexing/query/delete/update logic.
+- `src/coderag/api/routes.py`, `src/coderag/api/schemas.py`: stable response/error contracts.
+- `src/coderag/mcp/handlers.py`, `src/coderag/mcp/tools.py`, `src/coderag/cli.py`: MCP/CLI parity and citation/no-context propagation.
+- `tests/test_m3_citations.py`, `tests/test_api_routes.py`, `tests/test_mcp_handlers.py`, `tests/test_ui_handlers.py`, `tests/test_m6_interfaces_docs.py`, `tests/test_m1_services.py`: deterministic behavior contracts.
+- `evals/config.json`, `evals/runs/`, `evals/reports/`: behavior-level EvalFly coverage and run evidence.
+- `docs/superpowers/plans/`: run records, AC-0..AC-10 review, E2E evidence.
+
+---
+
+### Task 1: Finish strict citation fallback without model-dependent citation quality
+
+**Files:**
+- Modify: `src/coderag/generation/generator.py`
+- Modify: `tests/test_m3_citations.py`
+- Modify: `evals/config.json`
+- Modify: `tests/test_m1_services.py`
+
+**Interfaces:**
+- Consumes: `CitationVerifier.verify(citations, retrieved_chunks)`.
+- Produces: `Response.answer` that uses deterministic evidence fallback when model citations are missing/unverified; EvalFly smoke points at the new fallback tests.
+
+- [x] **Step 1: Write failing tests for unverified and omitted model citations**
+
+Add tests named:
+
+```python
+def test_response_generator_falls_back_to_verified_evidence_when_model_citations_do_not_verify(): ...
+def test_response_generator_falls_back_to_verified_evidence_when_model_omits_citations(): ...
+```
+
+Expected before implementation: the first fails because unverified citations leave `grounded=False`; the second fails because no citations from model leaves `grounded=False`.
+
+- [x] **Step 2: Implement deterministic fallback**
+
+In `ResponseGenerator.generate`, parse model citations, verify them, and when not grounded build an evidence-only answer from retrieved chunks with chunk-derived citations. Re-run verifier on fallback citations.
+
+- [x] **Step 3: Update EvalFly smoke pointers and isolate env-sensitive test**
+
+Update `evals/config.json` to look for the new fallback tests. In `test_provider_config_service_reads_documented_model_profile_from_env_file`, clear `MODEL_PROFILE` and `MODEL_LLM_PROVIDER` via `monkeypatch.delenv` so the persistent user shell profile cannot override the temp `.env` fixture.
+
+- [x] **Step 4: Verify**
+
+Run:
+
+```bash
+PYTHONPATH=src .venv/bin/python -m pytest tests/test_m3_citations.py tests/test_m1_services.py -q
+.venv/bin/python scripts/evalfly_smoke.py --suite smoke
+```
+
+Expected: tests pass and EvalFly smoke passes.
+
+---
+
+### Task 2: Snapshot-backed citation verifier
+
+**Files:**
+- Modify: `src/coderag/models/document.py`
+- Modify: `src/coderag/services/registry.py`
+- Modify: `src/coderag/services/indexing.py`
+- Modify: `src/coderag/generation/citations.py`
+- Modify: `tests/test_m3_citations.py`
+- Modify: `tests/test_m2_registry.py`
+
+**Interfaces:**
+- Produces: `DocumentMetadata.content_hash: str` using SHA-256 of file content.
+- Produces: `RepositoryRegistry.get_file_record(repo_id: str, file_path: str) -> RepositoryFileRecord | None`.
+- Produces: `RepositoryRegistry.get_chunk_records(repo_id: str, file_path: str | None = None) -> list[RepositoryChunkRecord]` if absent.
+- Produces: `CitationVerifier(snapshot_provider: CitationSnapshotProvider | None = None)` where provider can validate file existence, line bounds, and stored hash/range metadata.
+
+- [ ] **Step 1: Add failing hash/line-bound tests**
+
+Add tests for:
+
+```python
+def test_citation_verifier_rejects_out_of_snapshot_line_range(): ...
+def test_citation_verifier_rejects_snapshot_hash_mismatch(): ...
+def test_document_from_file_records_content_hash(): ...
+```
+
+Expected initial failures: verifier has no snapshot provider and document metadata lacks hash.
+
+- [ ] **Step 2: Implement content hashes**
+
+`Document.from_file` computes:
+
+```python
+content_hash = hashlib.sha256(content.encode("utf-8")).hexdigest()
+```
+
+Store on `DocumentMetadata`.
+
+- [ ] **Step 3: Persist file/chunk hashes**
+
+When indexing, pass file `line_count` and `content_hash` into `record_file_metadata`. For chunks, persist deterministic hash of the chunk content. Ensure existing schema column `content_hash` is populated.
+
+- [ ] **Step 4: Add registry lookup methods**
+
+Add file/chunk record getters used by tests and verifier. Do not change existing public methods unless necessary.
+
+- [ ] **Step 5: Make verifier snapshot-aware**
+
+Verifier keeps current overlap behavior when no provider is supplied for backward-compatible tests. With provider supplied, reject citations when:
+
+```text
+invalid_line_range
+file_not_indexed
+line_range_out_of_snapshot
+line_range_not_retrieved
+content_hash_mismatch
+```
+
+- [ ] **Step 6: Verify focused tests**
+
+Run:
+
+```bash
+PYTHONPATH=src .venv/bin/python -m pytest tests/test_m3_citations.py tests/test_m2_registry.py -q
+```
+
+Expected: pass.
+
+---
+
+### Task 3: Interface propagation for fallback, no-context, and errors
+
+**Files:**
+- Modify: `tests/test_api_routes.py`
+- Modify: `tests/test_mcp_handlers.py`
+- Modify: `tests/test_m6_interfaces_docs.py`
+- Modify: `tests/test_ui_handlers.py`
+- Modify if needed: `src/coderag/api/routes.py`, `src/coderag/mcp/handlers.py`, `src/coderag/cli.py`, `src/coderag/ui/handlers.py`
+
+**Interfaces:**
+- Consumes: `Response` with `answer`, `citations`, `citation_verifications`, `retrieved_chunks`, `grounded`.
+- Produces: adapter tests proving API/MCP/CLI/UI preserve fallback and no-context semantics.
+
+- [ ] **Step 1: Add fallback propagation tests**
+
+Use a canonical fallback `Response` with one `RetrievedChunk`, one `Citation`, one verified `CitationVerification`, and answer text containing `verified evidence`.
+
+Assert:
+- API `/query` response preserves `grounded`, `citations`, `citation_verifications`, `retrieved_chunks`.
+- MCP `query_code` output preserves `grounded`, `citations`, `citation_verifications`, `evidence`.
+- CLI JSON includes grounded status and citations.
+- UI `ask_question` renders answer, evidence, and `Grounded (verified citations)`.
+
+- [ ] **Step 2: Add no-context tests**
+
+Use a response with answer `I could not find information about this in the indexed repository.`, empty citations/evidence, and `grounded=False`.
+
+Assert every adapter reports no evidence and does not claim grounded.
+
+- [ ] **Step 3: Fix adapter gaps only if tests fail**
+
+Do not add new abstractions. Map existing response fields through each adapter.
+
+- [ ] **Step 4: Verify focused adapter tests**
+
+Run:
+
+```bash
+PYTHONPATH=src .venv/bin/python -m pytest tests/test_api_routes.py tests/test_mcp_handlers.py tests/test_m6_interfaces_docs.py tests/test_ui_handlers.py -q
+```
+
+Expected: pass.
+
+---
+
+### Task 4: UI service-seam cutover
+
+**Files:**
+- Modify: `src/coderag/ui/handlers.py`
+- Modify: `src/coderag/services/indexing.py` only for progress callback support if necessary
+- Modify: `tests/test_ui_handlers.py`
+
+**Interfaces:**
+- Consumes: `IndexingService.index_repository`, `IndexingService.update_repository`, `IndexingService.delete_repository`, `RetrievalService.query_code`, registry list/get APIs.
+- Produces: UI handlers that do not duplicate core indexing/query/delete/update semantics.
+
+- [ ] **Step 1: Add tests that UI delegates to services**
+
+Assert UI indexing/deletion/query calls injected fake services and maps their result to existing Gradio output strings.
+
+- [ ] **Step 2: Introduce service injection on UIHandlers**
+
+Constructor accepts optional `indexing_service`, `retrieval_service`, and `registry`; defaults remain current production instances.
+
+- [ ] **Step 3: Replace UI query path with RetrievalService**
+
+`ask_question` validates UI fields, then calls `retrieval_service.query_code(repo_id, question, top_k)` and formats the returned response.
+
+- [ ] **Step 4: Replace delete/update/index paths with IndexingService where feasible**
+
+Delete duplicated logic after tests cover the replacement. Preserve user-facing messages.
+
+- [ ] **Step 5: Verify UI tests**
+
+Run:
+
+```bash
+PYTHONPATH=src .venv/bin/python -m pytest tests/test_ui_handlers.py -q
+```
+
+Expected: pass.
+
+---
+
+### Task 5: EvalFly behavior suites and release evidence
+
+**Files:**
+- Modify: `evals/config.json`
+- Create: `evals/runs/20260702-portfolio-complete-*.json`
+- Create: `evals/reports/20260702-portfolio-complete-*.md`
+- Create: `docs/superpowers/plans/2026-07-02-coderag-portfolio-e2e-plan.md`
+- Create: `docs/superpowers/plans/2026-07-02-coderag-portfolio-e2e-run-record.md`
+- Create: `docs/superpowers/plans/2026-07-02-coderag-portfolio-readiness-review.md`
+
+**Interfaces:**
+- Produces: evidence records for CLI/API/MCP/UI and AC-0..AC-10.
+
+- [ ] **Step 1: Add deterministic EvalFly cases**
+
+Promote coverage pointers into behavior assertions for these suites:
+
+```text
+smoke
+retrieval
+citations
+graph
+interfaces
+security
+```
+
+- [ ] **Step 2: Freeze E2E criteria before driving app**
+
+For each flow define `pass_requires`, `fail_if`, `inconclusive_if`, `required_evidence`, and negative seeds:
+- CLI: clean installed package, index fixture/public repo, context/query output, citation validity, missing-provider negative.
+- API: real server health/index/poll/retrieve/context/citation verification, hostile origin/CORS, invalid repo id.
+- MCP: streamable HTTP or stdio client list/index/search/context plus unknown repo/invalid citation negative.
+- UI: browser-visible Gradio index/query/manage flow plus query-before-ready negative.
+
+- [ ] **Step 3: Run E2E and save evidence**
+
+Use temp data dirs and sanitized env. Save commands, logs, screenshots, and observed outputs. Do not print API keys.
+
+- [ ] **Step 4: AC-0..AC-10 readiness review**
+
+Map every acceptance criterion to PASS/FAIL/INCONCLUSIVE with file paths and command evidence.
+
+---
+
+### Task 6: Documentation claim alignment
+
+**Files:**
+- Modify: `README.md`
+- Modify: `docs/superpowers/plans/2026-06-30-m7-release-run-record.md` only if adding an appendix, not rewriting history.
+- Modify/Create: portfolio completion evidence docs from Task 5.
+
+**Interfaces:**
+- Produces: user-facing claims matching tested behavior.
+
+- [ ] **Step 1: Update README quickstart**
+
+Add a clean quickstart that indexes a small repo/fixture, runs context/search/query, and explains `retrieval-only` vs cloud provider mode.
+
+- [ ] **Step 2: Qualify claims**
+
+State that CodeRAG is portfolio/local complete after the new evidence. Explicitly exclude hosted SaaS/multi-user production claims.
+
+- [ ] **Step 3: Link evidence**
+
+Link E2E run record, EvalFly reports, and readiness review.
+
+---
+
+## Completion Gate
+
+Before calling CodeRAG complete, Main must run and record:
+
+```bash
+PYTHONPATH=src .venv/bin/python -m pytest tests/test_m0_baseline.py tests/test_m1_services.py tests/test_m2_registry.py tests/test_citations.py tests/test_m3_citations.py tests/test_api_routes.py tests/test_mcp_handlers.py tests/test_mcp_tools.py tests/test_ui_handlers.py tests/test_m4_hybrid_retrieval.py tests/test_m5_code_graph.py tests/test_m6_interfaces_docs.py

+.venv/bin/python scripts/evalfly_smoke.py --suite smoke
+```
+
+Then run the frozen CLI/API/MCP/UI E2E plan and save the run record. If any criterion is not exercised, the final verdict must say `INCONCLUSIVE`, not `PASS`.

+# CodeRAG Portfolio E2E Evaluation Plan
+
+Source of truth: approved `Portfolio complete` scope in this session plus `docs/superpowers/plans/2026-07-02-coderag-portfolio-complete.md`.
+
+Adapter constraint: browser-visible UI will use the strongest available in-harness browser adapter. If the harness cannot expose a physical headed browser, UI evidence is screenshots/DOM observations and verdict records the fidelity gap.
+
+Temporary environment:
+- Use isolated temp directories for `DATA_DIR`, `VECTORSTORE_PERSIST_DIRECTORY`, and `INGESTION_REPOS_CACHE_DIR`.
+- Use `MODEL_PROFILE=cloud`, `MODEL_LLM_PROVIDER=groq`, and existing `MODEL_LLM_API_KEY` from environment without printing it.
+- Public test repository: `https://github.com/pallets/markupsafe`.
+
+## Criterion C1 — CLI quickstart flow
+
+pass_requires:
+- Installed/local CLI can index the public repository through `coderag index`.
+- `coderag repos --format json` shows one ready MarkupSafe repository with chunks.
+- `coderag context-pack <repo> "escape function" --format json` returns snippets with citations and no LLM dependency.
+- `coderag query <repo> "What does MarkupSafe's escape function do? Cite the relevant source lines." --format json` returns `grounded=true`, non-empty citations, non-empty citation_verifications, and evidence.
+
+fail_if:
+- Index command exits non-zero.
+- Repo is not ready after index.
+- Query returns ungrounded, empty citations, or empty evidence.
+- Output leaks the API key.
+
+inconclusive_if:
+- GitHub/network/provider is unavailable.
+- Provider rejects the test key or rate-limits.
+
+required_evidence:
+- Sanitized command outputs for index/repos/context/query.
+- JSON assertions for repo status, context snippets, grounded query, citation verification.
+
+negative_seed:
+- Run `coderag query missing-repo "What?" --format json`; it must fail closed with non-zero exit and no key leak.
+
+## Criterion C2 — REST API real server flow
+
+pass_requires:
+- Real `coderag serve` server starts on loopback.
+- `/health` returns 200.
+- `/api/v1/repos/index` accepts public repo and returns a repo_id.
+- Polling `/api/v1/repos/{repo_id}` reaches `ready` with chunks.
+- `/api/v1/context-pack` returns snippets/citations without generation.
+- `/api/v1/query` returns grounded answer with verified citations/evidence.
+
+fail_if:
+- Server binds outside loopback in the test config.
+- Index/query returns 5xx.
+- CORS allows an untrusted hostile origin with credentials.
+- Invalid repo id does not fail closed.
+
+inconclusive_if:
+- Network/provider unavailable or index timeout before readiness.
+
+required_evidence:
+- Startup command/env summary without secrets.
+- HTTP statuses and JSON assertion summaries.
+
+negative_seed:
+- Hostile Origin request and invalid repo id request.
+
+## Criterion C3 — MCP streamable HTTP flow
+
+pass_requires:
+- MCP streamable HTTP client initializes against `/mcp/`.
+- `list_tools` includes repository, query, context, hybrid search, and graph tools.
+- `list_repositories` returns indexed MarkupSafe repo.
+- `get_context_pack` returns citation-bearing snippets.
+- `query_code` returns grounded answer and verified citation metadata.
+
+fail_if:
+- MCP handshake fails.
+- Tool output is not JSON-serializable.
+- Unknown repo does not fail closed.
+
+inconclusive_if:
+- MCP SDK unavailable in the active venv.
+
+required_evidence:
+- Tool list count/names, sanitized tool-call result assertions.
+
+negative_seed:
+- `query_code` with unknown repo id.
+
+## Criterion C4 — UI browser flow
+
+pass_requires:
+- UI root loads CodeRAG tabs.
+- Index Repository tab can index MarkupSafe or observe already-indexed MarkupSafe in the same temp app state.
+- Ask Questions tab can select the repository, ask the escape-function question, and display answer, citations/evidence, and `Grounded (verified citations)`.
+- Manage Repositories tab lists the repository.
+
+fail_if:
+- UI cannot load.
+- Query result is ungrounded or lacks citations/evidence.
+- User-facing status hides failure.
+
+inconclusive_if:
+- Browser adapter cannot interact with Gradio due harness limitation; record screenshot/DOM gap.
+
+required_evidence:
+- Screenshot path(s), observed text/status, and relevant DOM/control evidence.
+
+negative_seed:
+- Query with no selected repo or empty question returns a closed UI validation message.

+# CodeRAG Portfolio E2E Run Record
+
+Date: 2026-07-06
+Scope: approved `Portfolio complete` local/portfolio-grade readiness, not hosted SaaS or multi-user production readiness.
+Plan: `docs/superpowers/plans/2026-07-02-coderag-portfolio-e2e-plan.md`.
+
+## Project profile
+
+- Repo: `~/Documents/CodeRAG`.
+- Runtime: local `.venv/bin/coderag` CLI, FastAPI/Gradio server via `coderag serve`, MCP streamable HTTP at `/mcp/`.
+- Test repository: `https://github.com/pallets/markupsafe`.
+- Temp state: `/tmp/coderag-portfolio-e2e.qUYOGm/` with isolated data, vector store, and repo cache.
+- Provider: `MODEL_PROFILE=cloud`, `MODEL_LLM_PROVIDER=groq`, `MODEL_LLM_API_KEY` inherited from environment and not printed.
+- Browser adapter: OMP `browser` opened a hidden/headless Chromium tab. Fidelity gap: not a physical headed browser window, but screenshots/DOM/control evidence were captured.
+
+## Frozen criteria
+
+Criteria C1-C4 were frozen in `2026-07-02-coderag-portfolio-e2e-plan.md` before driving CLI/API/MCP/UI.
+
+## Scope classification
+
+- In scope: strict citation fallback, snapshot-backed citation verification, adapter propagation, UI query/delete service seams, EvalFly suite filtering, real CLI/API/MCP/UI local flows.
+- Explicitly out of scope: hosted deployment, auth/multi-user isolation, billing/rate-limit/SRE guarantees, PyPI publish, GitHub Actions run after this local diff.
+- Fidelity gaps: UI browser was headless/hidden; server port env override was not honored by `coderag serve`, so server ran on default loopback `127.0.0.1:8000`.
+
+## Criterion C1 — CLI quickstart flow
+
+Verdict: PASS.
+
+Production path:
+`coderag index` → URL validation → clone public repo → file filtering → chunking → embeddings → ChromaDB → SQLite registry/job state → `coderag repos/context-pack/query` adapters → retrieval/generation/citation verification.
+
+Evidence:
+- Index command: `.venv/bin/coderag index https://github.com/pallets/markupsafe` with isolated env.
+  - Exit: 0.
+  - Observed repo ID: `16e91246-4360-4538-b43e-a2ca6995fbeb`.
+  - Observed: `Files processed: 13`, `Chunks indexed: 101`.
+- Repos JSON: `.venv/bin/coderag repos --format json`.
+  - Observed one repo `pallets/markupsafe`, `status: ready`, `chunk_count: 101`.
+- Context pack: `.venv/bin/coderag context-pack 16e91246 "escape function" --format json`.
+  - Observed snippets with citations including `[src/markupsafe/__init__.py:332-354]`, `[src/markupsafe/__init__.py:48-61]`, `[src/markupsafe/_native.py:1-8]`.
+  - JSON stdout was verified separately with Bun subprocess; logs were on stderr and stdout parsed as JSON.
+- Query: `.venv/bin/coderag query 16e91246 "What does MarkupSafe's escape function do? Cite the relevant source lines." --format json`.
+  - Observed `grounded: true`.
+  - Observed non-empty citations and all citation verifications `verified: true`.
+  - Evidence included `src/markupsafe/__init__.py:24-45` and `src/markupsafe/_native.py:1-8`.
+
+Negative case:
+- `.venv/bin/coderag query missing-repo "What?" --format json`.
+  - Exit: 1.
+  - Observed closed JSON error: `Repository not found: missing-repo`, `grounded: false`, empty citations/evidence.
+  - No API key printed.
+
+## Criterion C2 — REST API real server flow
+
+Verdict: PASS.
+
+Production path:
+`coderag serve` → FastAPI/Gradio app → `/health` and `/api/v1/*` routes → shared registry/retrieval services → ChromaDB/SQLite/provider.
+
+Evidence:
+- Server command: `.venv/bin/coderag serve` with isolated env.
+  - Intended `SERVER_HOST=127.0.0.1`, `SERVER_PORT=8765`; observed app available on default `127.0.0.1:8000`.
+  - `/health`: `{"status":"healthy","app":"CodeRAG","version":"0.1.2"}`.
+- `/api/v1/repos`: returned MarkupSafe repo ready with 101 chunks.
+- `/api/v1/context-pack`: POST returned snippet/citation evidence for `escape function`.
+- `/api/v1/query`: POST returned `grounded: true`, 5 citations, 5 citation_verifications, 5 retrieved_chunks. Assertion executed via JS fetch and failed if any citation verification was false or evidence was empty.
+
+Negative cases:
+- Hostile CORS preflight with `Origin: https://evil.example` returned `HTTP/1.1 400 Bad Request` and body `Disallowed CORS origin`.
+- Invalid repo query returned `HTTP/1.1 404 Not Found` with `{"detail":"Repository not found"}`.
+
+## Criterion C3 — MCP streamable HTTP flow
+
+Verdict: PASS.
+
+Production path:
+MCP streamable HTTP client → `/mcp/` → MCP handlers → shared registry/retrieval services → ChromaDB/SQLite/provider.
+
+Evidence:
+- Probe script: `/tmp/coderag_mcp_e2e.py`.
+- Command: `.venv/bin/python /tmp/coderag_mcp_e2e.py`.
+- MCP initialize returned server `CodeRAG`.
+- `list_tools` returned 12 tools: `index_repository`, `query_code`, `list_repositories`, `get_repository_info`, `delete_repository`, `update_repository`, `search_code`, `search_hybrid`, `get_context_pack`, `find_symbol`, `find_references`, `get_blast_radius`.
+- `list_repositories` returned ready MarkupSafe repo with 101 chunks.
+- `get_context_pack` returned citation-bearing snippets.
+- `query_code` returned `grounded: true` with verified citations.
+
+Negative case:
+- `query_code` with `missing-repo` returned a closed structured result: empty answer/citations/evidence, `grounded: false`, and `error: Repository not found: missing-repo`.
+
+Raw evidence artifact in session: `artifact://139`.
+
+## Criterion C4 — UI browser flow
+
+Verdict: PASS with adapter fidelity gap.
+
+Production path:
+Browser → Gradio UI → UI handlers → shared retrieval service for query → ChromaDB/SQLite/provider → UI answer/status/evidence render.
+
+Evidence:
+- Browser opened `http://127.0.0.1:8000/` with title `CodeRAG - Code Q&A with Citations`.
+- Ask Questions tab selected repository `pallets/markupsafe (101 chunks)`.
+- Asked: `What does MarkupSafe escape do? Cite relevant lines.`
+- Status textbox value: `Grounded (verified citations)`.
+- UI displayed answer, citations, and evidence.
+- Screenshot: `/tmp/coderag-portfolio-ui-e2e.png`.
+- Manage Repositories tab refresh displayed row: `16e91246`, `pallets/markupsafe`, `main`, `101`, `ready`, indexed timestamp.
+
+Negative case:
+- Cleared question and clicked Ask.
+- Status textbox value: `Please enter a question`.
+
+Fidelity gap:
+- Browser adapter reported `Opened tab "coderag" on headless browser (hidden)`. This validates DOM/UI behavior and screenshot evidence, but not a physically visible browser window.
+
+## Verification gates after implementation
+
+- Focused full project target suite: `PYTHONPATH=src .venv/bin/python -m pytest tests/test_m0_baseline.py tests/test_m1_services.py tests/test_m2_registry.py tests/test_citations.py tests/test_m3_citations.py tests/test_api_routes.py tests/test_mcp_handlers.py tests/test_mcp_tools.py tests/test_ui_handlers.py tests/test_m4_hybrid_retrieval.py tests/test_m5_code_graph.py tests/test_m6_interfaces_docs.py`
+  - Final result after README/evidence edits: `142 passed, 2 warnings`.
+- Ruff focal gate: `.venv/bin/ruff check ...`
+  - Result: `OK`.
+- EvalFly deterministic suites:
+  - `smoke`: 16 cases passed.
+  - `retrieval`: 4 cases passed.
+  - `citations`: 3 cases passed.
+  - `graph`: 5 cases passed.
+  - `interfaces`: 5 cases passed.
+  - `security`: 1 case passed.
+
+## Overall verdict
+
+PASS for local/portfolio completion evidence after the code/test/doc changes in this worktree. Final local gates were rerun after documentation edits.
+
+NOT CLAIMED:
+- Hosted SaaS production readiness.
+- Physical headed-browser observation.
+- GitHub Actions CI on this uncommitted diff.
+- Published package/release.
+
+## Teardown
+
+- Server background job completed by harness timeout after evidence capture; no running job remains.
+- Browser tab was closed after final verification.
+- Temp data under `/tmp/coderag-portfolio-e2e.qUYOGm/` may be removed after no longer needed.

+# CodeRAG Portfolio Readiness Review
+
+Scope: local/portfolio complete verified codebase context engine. This review intentionally does not evaluate hosted SaaS production readiness.
+
+Evidence sources:
+- Implementation plan: `docs/superpowers/plans/2026-07-02-coderag-portfolio-complete.md`
+- E2E plan: `docs/superpowers/plans/2026-07-02-coderag-portfolio-e2e-plan.md`

+- Existing roadmap: `docs/superpowers/plans/2026-06-27-coderag-2-production-roadmap.md`
+
+## Verdict table
+
+| Criterion | Verdict | Evidence |
+| --- | --- | --- |
+| AC-0 Governance and scope | PASS | Current plan narrows claim to local/portfolio complete and excludes SaaS/multi-user production. |
+| AC-1 Reproducible baseline | PASS | Targeted pytest suite passed: 142 tests, 2 dependency warnings; Ruff focal gate OK. |
+| AC-2 Safe defaults/privacy profiles | PASS | Security EvalFly suite passed; CORS hostile origin failed closed; API key never printed in evidence. |
+| AC-3 Durable registry/job state | PASS | MarkupSafe persisted through CLI/server/UI/MCP flows from isolated SQLite/vector state; registry tests passed. |
+| AC-4 Hybrid retrieval/context packs | PASS | CLI/API/MCP context-pack returned citation-bearing snippets; retrieval EvalFly suite passed. |
+| AC-5 Verified citations | PASS | Snapshot-backed verifier added; strict fallback added; CLI/API/MCP/UI query returned grounded verified citations. |
+| AC-6 Code graph | PASS for portfolio scope | Graph suite deterministic checks passed; real graph E2E beyond tool availability remains not deeply exercised in this run. |
+| AC-7 Context packs | PASS | CLI/API/MCP context pack evidence captured with snippets, citations, scores, budgets. |
+| AC-8 Interfaces | PASS | CLI/API/MCP/UI real flows passed; adapter propagation tests added for fallback/no-context. |
+| AC-9 EvalFly gates | PASS for deterministic local harness | `smoke`, `retrieval`, `citations`, `graph`, `interfaces`, `security` suites passed via repository-local deterministic runner. |
+| AC-10 Release readiness | PASS for local/portfolio claim; NOT PASS for SaaS production | Clean local E2E evidence exists for CLI/API/MCP/UI. GitHub Actions on this uncommitted diff and hosted deployment are not claimed. |
+
+## Remaining limitations
+
+- UI E2E used hidden/headless browser adapter; physical headed browser observation remains a fidelity gap.
+- `coderag serve` ignored the attempted `SERVER_PORT=8765` env override and served on default loopback port 8000; not blocking for local portfolio completion, but worth documenting/fixing if configurable port is part of a future release contract.
+- UI streaming index and incremental update still own adapter-specific progress code; query/delete paths are now service-backed. Full streaming progress callback support in `IndexingService` is a future hardening slice.
+- EvalFly suites are deterministic repository-local assertions, not external EvalFly CLI benchmark artifacts.
+- No GitHub Actions run exists for this uncommitted worktree diff until the user approves commit/push/PR.
+
+## Release claim allowed
+
+Allowed: “CodeRAG is local/portfolio complete as a verified codebase context engine with CLI, REST, MCP, and Gradio UI flows demonstrated against a real public repository, snapshot-backed citation checks, and deterministic local gates.”
+
+Not allowed: “Production SaaS ready”, “hosted multi-user ready”, “physically watched headed-browser E2E passed”, or “CI green on remote” until those are separately proven.

 - `coderag serve` ignored the attempted `SERVER_PORT=8765` env override and served on default loopback port 8000; not blocking for local portfolio completion, but worth documenting/fixing if configurable port is part of a future release contract.
 - UI streaming index and incremental update still own adapter-specific progress code; query/delete paths are now service-backed. Full streaming progress callback support in `IndexingService` is a future hardening slice.
 - EvalFly suites are deterministic repository-local assertions, not external EvalFly CLI benchmark artifacts.

 Allowed: “CodeRAG is local/portfolio complete as a verified codebase context engine with CLI, REST, MCP, and Gradio UI flows demonstrated against a real public repository, snapshot-backed citation checks, and deterministic local gates.”
