tracking, and deep code understanding at scale. + +## Current Milestone: v0.7 Codebase Context Backend + +**Goal:** Turn CodeBadger from an MCP-only analysis surface into a backend that accepts

+ +**Created:** 2026-08-09 +**Milestone:** v0.7 Codebase Context Backend +**Granularity:** Standard + +## Phase 5: Secure Ingestion & Version Catalog + +**Goal:** Synchronize an authenticated Git remote branch into an immutable, content-addressed project version safely. + +**Requirements:** INGEST-01, INGEST-02, INGEST-03 + +**Success Criteria:** +1. An authenticated client can register a GitHub, GitLab, or Azure DevOps remote with a selected branch and trigger an explicit update without waiting for Joern. +2. The update uses validated Git CLI fetch/ref resolution in an isolated workspace; credentials never persist in URLs, Git config, logs, or responses. +3. Each resolved commit produces an immutable version with commit SHA and manifest; an unchanged branch returns the existing version rather than creating a duplicate. + +## Phase 6: Durable CPG Lifecycle & Backend Contract + +**Goal:** Connect immutable versions to the existing durable CPG queue and expose REST/MCP lifecycle operations with idempotent status semantics. + +**Requirements:** CPG-01, CPG-02, CPG-03, CPG-04, API-01, API-02 + +**Depends on:** Phase 5 + +**Success Criteria:** +1. A version enqueues one durable CPG build and reuses existing Joern pool/admission/locks. +2. REST and MCP return identical lifecycle states, progress, queue position, retry information, and sanitized errors. +3. Duplicate submissions deduplicate; failed jobs retry safely; cancelled/interrupted jobs leave no partial artifact; restart reconciliation is tested. +4. Equivalent content and build options reuse the CPG cache while a ready version remains immutable. + +## Phase 7: Cited Hybrid Context Retrieval + +**Goal:** Turn a ready CPG and source snapshot into bounded, explainable context packs for AI agents. + +**Requirements:** CTX-01, CTX-02, CTX-03, CTX-04, CTX-05 + +**Depends on:** Phase 6 + +**Success Criteria:** +1. Ready versions expose symbol/file/source-span indexes with stable relative-path and line metadata. +2. Context queries combine exact symbol resolution, Postgres lexical/trigram search, and capped Joern graph expansion with deterministic ranking/deduplication. +3. Every response enforces explicit item/byte/token/node/time budgets and marks truncation; every item cites version digest, path, inclusive lines, symbol, and selection reason. +4. Public context operations reject raw CPGQL while internal/admin access remains separately gated. + +## Phase 8: Authorization, Quotas & Production Verification + +**Goal:** Make the new backend safe and diagnosable under untrusted uploads and agent traffic. + +**Requirements:** API-03, API-04 + +**Depends on:** Phase 6, Phase 7 + +**Success Criteria:** +1. Authentication and project/version authorization are enforced consistently across REST and MCP; cross-project access tests fail closed. +2. Upload, build, and retrieval quotas/backpressure return typed errors and expose correlation IDs, metrics, audit events, and sanitized diagnostics. +3. End-to-end tests cover malicious archives, restart/retry, cache reuse, context citations/truncation, and REST/MCP parity. +4. Deployment documentation states the single-tenant/Docker-socket posture and required reverse-proxy/worker isolation controls. + +--- +*Roadmap created: 2026-08-09 for v0.7* diff --git a/.planning/STATE.md b/.planning/STATE.md new file mode 100644 index 0000000..2a3e159 --- /dev/null +++ b/.planning/STATE.md @@ -0,0 +1,21 @@ +# Project State — CodeBadger + +## Current Status +- **Current Milestone:** v0.7 Codebase Context Backend +- **Current Phase:** 08-authorization-quotas-production-verification (COMPLETED) +- **All Core Phases (05 - 08):** Complete + +## Phase Execution History +- **Phase 05:** Secure Ingestion & Version Catalog (Completed) +- **Phase 06:** Durable CPG Lifecycle & Backend Contract Parity (Completed) +- **Phase 07:** Cited Hybrid Context Retrieval (Completed) +- **Phase 08:** Authorization, Quotas & Production Verification (Completed) + - 08-01: JWT Authentication, User Seeding & Tenancy Service (Completed) + - 08-02: Auth Middleware & Route/MCP Protection (Completed) + - 08-03: Correlation Tracking & Structured Audit Logging (Completed) + - 08-04: Rate Limiting, Backpressure Quotas & Error Sanitization (Completed) + - 08-05: End-to-End & Security Parity Verification (Completed) + +## Verification +- Total tests: 130 passing across unit and integration test suites. +- Code coverage: REST routes, FastMCP tools, auth middleware, correlation tracking, rate limiting, quotas, audit logging. diff --git a/.planning/config.json b/.planning/config.json new file mode 100644 index 0000000..f4d7631 --- /dev/null +++ b/.planning/config.json @@ -0,0 +1,18 @@ +{ + "mode": "interactive", + "granularity": "standard", + "parallelization": true, + "commit_docs": true, + "model_profile": "balanced", + "workflow": { + "research": true, + "plan_check": true, + "verifier": true, + "nyquist_validation": false, + "auto_advance": false, + "discuss_mode": "discuss", + "mvp_mode": false, + "context_coverage_gate": true, + "post_planning_gaps": true + } +} diff --git a/.planning/phases/05-secure-ingestion-version-catalog/05-01-PLAN.md b/.planning/phases/05-secure-ingestion-version-catalog/05-01-PLAN.md new file mode 100644 index 0000000..2b2bc73 --- /dev/null +++ b/.planning/phases/05-secure-ingestion-version-catalog/05-01-PLAN.md @@ -0,0 +1,94 @@ +--- +phase: 05-secure-ingestion-version-catalog +plan: 01 +type: tdd +wave: 1 +depends_on: [] +files_modified: + - src/models.py + - src/services/project_version_service.py + - src/services/credential_store.py + - src/utils/postgres_db_manager.py + - src/utils/validators.py + - tests/test_project_version_contract.py + - tests/test_credential_store.py +autonomous: true +requirements: [INGEST-01, INGEST-02, INGEST-03] +--- + + +Define the project/source/version contract and persistence seam that makes a Git +commit an immutable CodeBadger version.

AI Systems Best Practices + +### Structured Outputs with Pydantic + +```python +class VersionResult(BaseModel): + project_id: str + version_id: str + commit_sha: str = Field(pattern=r"^[0-9a-f]{40}$") + status: str # created | unchanged +``` + +Validate provider results before persistence; a failed parse or non-canonical SHA +must fail closed and return a sanitized typed error. + +### Async-First Design + +Run blocking Git CLI commands through async subprocess APIs with timeouts and +cancellation cleanup. Never block the MCP/REST event loop with synchronous GitPython +or shell calls. + +### Prompt Engineering Discipline + +N/A — no model prompt is produced in this phase. Future context tools must make +provenance fields machine-readable rather than relying on prompt prose. + +### Context Window Management + +N/A — snapshot manifests and commit provenance are structured metadata, not prompt context. + +### Cost and Latency Budget + +Bound fetch/checkout by timeout, shallow/ref-scoped fetch where safe, workspace size, +and one active sync per project. Cache unchanged revisions by commit/config identity. + +--- + +## 5.

This phase covers exactly-one build per version, stable lifecycle states, durable recovery, and a backend contract whose REST responses and MCP tools return the same schemas. It does not build context retrieval (Phase 7) nor auth/quotas (Phase 8). + + + + +## Implementation Decisions + +### Build trigger & job binding +- **D-01:** CPG builds auto-enqueue immediately after a version is created by sync. `POST /projects/{id}/versions/update` syncs the branch and schedules the build in one call. An unchanged branch returns the existing version and does not enqueue a duplicate job (Phase 5 dedup semantics). +- **D-02:** Lifecycle status is stored as a `build_status` column on the `project_versions` row, authoritative and single source of truth; no separate build table. Queue internals (running/retry) are written back onto the version as its state advances. +- **D-03:** "Exactly one durable build per version" is enforced by a DB partial unique index on `(job_type, version_id)` in the durable `jobs` table — DB-level guarantee, not just application logic. +- **D-04:** The durable queue stays keyed by `codebase_hash` (rest of the system unchanged); when a version's build starts, the version↔`codebase_hash`(+`cpg_path`) mapping is registered so post-build exposing/loading keeps working. Mapping registration is a build-start side effect, not a separate endpoint. + +### Lifecycle state model (CPG-02) +- **D-05:** Six-state model on `version.build_status`: `queued → building → loading → ready`, plus `failed` and `cancelled`. `loading` is a distinct sub-stage after the CPG file exists but before Joern exposes it — matches the existing `_STATUS_TO_PHASE` map. +- **D-06:** Version status detail exposes `queue_position`, `elapsed_ms`, `retry_count`, and sanitized error as optional fields in a JSON metadata column on the version row (nullable/zero when not applicable). All four are included now — CPG-02 names them explicitly. +- **D-07:** Failure errors are stored and surfaced only in sanitized form: `error_code` + human message, reusing Phase 5/GitManager error masking (no credentials, no host paths, no stack traces). Raw errors never persist. + +### Cancel, retry & recovery (CPG-03) +- **D-08:** Cancellation is explicit and user-initiated only (no timeout/auto-cancel). A cancel request on a non-final version flips status to `cancelled` with a DB-level guard preventing cancellation of a `ready`/`failed` version. +- **D-09:** Cancelling deletes partial artifacts (partial snapshot dir / unstaged CPG) but keeps the `project_versions` row with `status=cancelled`, so a future sync/retry can produce a fresh build without losing provenance. +- **D-10:** Retry is idempotent: `POST /versions/{id}/retry` on a `failed`/`cancelled` version re-enqueues exactly one job (version_id dedup still applies) and resets `build_status` to `queued`. Retrying an already-queued/running version returns the same single job rather than a duplicate. +- **D-11:** Startup reconciliation keeps `requeue_running_jobs()` for crash recovery, but adds a capped `retry_count` per job so a permanently failing build is not requeued forever; builds past the cap land in `failed` with a sanitized error. + +### REST surface & archive upload (API-01) +- **D-12:** REST routes are mounted on the same FastMCP/Starlette app, process, and port (shares the `services` dict and one HTTP server; no second port, no separate FastAPI app). +- **D-13:** Archive upload is in scope as a secondary source adapter: `POST /projects/{id}/versions` accepts a tarball and creates a version without needing a Git remote (Git remains primary; archive is an alternative genesis path). Phase 5's deferral was about not making upload the *primary* mechanism, not excluding it. +- **D-14:** RESTful resource shape with action verbs: `POST /projects`, `GET /projects` (list), `GET /projects/{id}`; `POST /projects/{id}/versions/update` (git sync + build), `POST /projects/{id}/versions` (archive upload); `GET /versions` (list), `GET /versions/{id}` (detail + status), `POST /versions/{id}/retry`, `POST /versions/{id}/cancel`; `DELETE /projects/{id}`. + +### MCP parity (API-02) +- **D-15:** MCP lifecycle tools (`project_create`, `project_list`, `version_sync`, `version_upload`, `version_list`, `version_get`, `version_retry`, `version_cancel`, `project_delete`) call the same service methods as REST and return envelopes with the same `id`/`status`/`phase`/`queue_position` fields — one contract, REST and MCP are interchangeable surfaces. + +### Auth & quotas posture +- **D-16:** Authentication and quotas are Phase 8 (API-03/04). Phase 6 REST/MCP lifecycle surfaces are unauthenticated shells; the response envelope and sanitization patterns are designed now so Phase 8 can bolt authorization on without breaking the contract. + +### Claude's Discretion +- Exact REST response envelope field enumeration, Starlette route added to FastMCP's app, how `queue_position`/`elapsed_ms` are computed (reuse `DurableCPGQueue.queue_position()`), metadata JSON column schema for status detail, archive upload validation (size limits, extraction removal of path traversal), and exact MCP tool argument names — standard contracts, subject to existing validation and no-shell rules. +- Archive→version content digest/commit identity mapping (archive has no commit SHA;

If state is `failed` or `cancelled`, reset `build_status` to `queued`, increment `retry_count`, re-enqueue in `jobs`. If state is `queued` or `building`, return current status without re-enqueue. + - **Cancel**: `POST /versions/{id}/cancel` or `version_cancel` MCP tool. Guard against cancelling `ready` or `failed` versions. Set `build_status = 'cancelled'`. Purge partial snapshot directories or unfinished `.cpg.bin` files. + - **Reconciliation**: `DurableCPGQueue.start()` checks running jobs. Increment `attempts`. If `attempts > max_retries` (default 3), fail job with `EXCEEDED_MAX_RETRIES` and mark version `failed`. Otherwise, requeue job. + +### CPG-04: Cache Reuse without Version Mutation +- **Requirement**: Equivalent source content and build options reuse existing content-addressed CPG cache without mutating ready versions. +- **Implementation**: + - Version ID is computed as `hashlib.sha256(f"{project_id}:{commit_sha}:{build_config}")`. + - Content digest is sha256 of tree content. + - If two versions share `content_digest` and `build_config`, CPG generation reuses existing `cpg.bin` artifact in `playground/cpgs/{codebase_hash}.cpg.bin` without rebuilding AST. + +### API-01: REST Endpoints +- **Requirement**: REST endpoints support project creation, archive upload, version listing/detail, build/status, and deletion. +- **Endpoints Breakdown**: + - `POST /projects`: Register project (`remote_url`, `default_branch`, `owner_scope`, optional `credential`). + - `GET /projects`: List projects for owner scope. + - `GET /projects/{id}`: Get project details. + - `DELETE /projects/{id}`: Delete project and associated versions/credentials. + - `POST /projects/{id}/versions/update`: Sync Git remote branch & auto-enqueue build. + - `POST /projects/{id}/versions`: Upload source archive (zip/tar.gz), create version & auto-enqueue build. + - `GET /versions/{id}`: Get version detail, `build_status`, `queue_position`, `elapsed_ms`, `retry_count`, `error`. + - `GET /projects/{id}/versions`: List versions for project. + - `POST /versions/{id}/retry`: Idempotent build retry. + - `POST /versions/{id}/cancel`: Cancel active build. + +### API-02: MCP Parity +- **Requirement**: MCP lifecycle tools call the same application services and return IDs/status schemas compatible with REST. +- **MCP Tools List**: + 1. `project_create` + 2. `project_list` + 3. `project_delete` + 4. `version_sync` + 5. `version_upload` + 6. `version_list` + 7. `version_get` + 8. `version_retry` + 9. `version_cancel` + +--- + +## 4. Key Technical Challenges & Mitigations + +### 4.1 Race Conditions in Concurrent Sync / Retry +- **Challenge**: Multiple clients calling `version_sync` or `version_retry` simultaneously for the same version could create duplicate jobs or race on database status updates. +- **Mitigation**: + - Use `asyncio.Lock` per project/version in service layers. + - Postgres Partial Unique Index `idx_jobs_version_active` guarantees single-active-job at the DB level (`ON CONFLICT` handled gracefully). + - Version status updates use `UPDATE project_versions SET build_status = ... WHERE id = ... AND build_status = ...` optimistic concurrency guards. + +### 4.2 Safe Archive Extraction (API-01 Upload) +- **Challenge**: Malicious zip/tar archives containing zip-slips (`../path/traversal`), symlinks to sensitive host files, or oversized files (decompression bombs). +- **Mitigation**: + - Validate every member path in tar/zip to verify it stays within destination root directory (`os.path.abspath(target_path).startswith(os.path.abspath(extract_dir))`). + - Reject symlinks/hardlinks in uploaded archives. + - Enforce total uncompressed size limit (e.g. 500 MB) and individual file count limits. + +### 4.3 Error Sanitization Consistency +- **Challenge**: Internal exceptions (e.g. Docker command stderr, Java heap OOM traces, host filesystem paths, Git tokens) could leak into API/MCP responses. +- **Mitigation**: + - Standardize error masking via a centralized `sanitize_error_detail(error: Exception | str) -> dict` returning `{"error_code": str, "message": str}`. + - Map known internal exception types (e.g., `GitOperationError`, `DockerException`, `TimeoutError`) to clean codes (`GIT_SYNC_FAILED`, `DOCKER_UNAVAILABLE`, `BUILD_TIMEOUT`, `OOM_KILLED`). + +--- + +## 5.

Only promote a snapshot after complete validation and extraction; then create/commit the version record and enqueue the job. A database transaction cannot atomically include filesystem promotion, so use a recoverable two-step protocol: stage under a server-generated directory, write a manifest and checksum, atomically rename to its final version directory, then commit metadata; startup reconciliation removes orphaned staging directories and marks incomplete versions failed/repairable. Never let the CPG worker read the staging directory. + +### Data Flow + +#### Upload, snapshot, and build + +1. An authenticated caller sends an archive plus project/version metadata and an idempotency key. +2. The transport applies body-size and rate limits. `ArchiveIngestionService` streams to a private, mode-`0700` staging directory with a server-generated filename; it does not trust archive member paths, archive filename, MIME type, or declared size. +3. The service inspects every member before extraction; rejects absolute/traversal paths, symlinks/hardlinks/devices/FIFOs, duplicate-normalized paths, excessive member count, compressed/uncompressed size ratio, depth, and unsupported archive types. Extract regular files only beneath the staging root with no-follow semantics and a cumulative byte cap. +4. It selects/validates a single source root, creates a manifest and content SHA-256, then promotes the snapshot to `playground/projects//versions//source` (or equivalent host path). The final directory is owned by the service and never caller-controlled. +5. `ProjectVersionService` persists `staged/queued` plus the version-to-legacy CPG cache key. `BuildJobService` enqueues one durable `generate_cpg` job. Return `202 Accepted` with version and job URLs; do not hold an upload request open for Joern. +6. Existing durable workers claim via `SKIP LOCKED`, transition `queued → building`, invoke the current generator using final source/CPG paths, and publish `ready` or `failed` with a sanitized error. The existing CPG path should be version-scoped, e.g. `.../versions//cpg/cpg.bin`, so different versions can coexist. +7. REST/MCP lifecycle adapters read the same version/job record. A ready version is queryable; building/failed versions return an explicit lifecycle response, never a connection-refused symptom. + +#### Semantic context retrieval + +1. A REST endpoint or MCP tool receives `{project_id, version_id, query or symbol, optional file/line hints, budget}`. +2. `ContextService` authorizes the version, requires `ready`, normalizes/clamps the request, and uses a strict maximum response budget. +3. Retrieval proceeds in explainable tiers: exact symbol/file lookup first; lexical candidate discovery second; bounded CPG relationships (definition, callers/callees, adjacent control/data-flow) third. It uses named/parameterized query templates and `QueryExecutor`, inheriting its timeout, row/output limits, Redis per-CPG lock, and auto-wake semantics. +4. The service deduplicates candidates, reads only cited snapshot files via a version-root-confined source reader, and packages compact excerpts. Each item carries `project_id`, `version_id`, repository-relative path, line range, symbol/relationship reason, and a stable citation ID. No absolute host path, raw Joern error, or unbounded node dump leaves the service. +5. The response declares truncation and retrieval limits. Cache only after authorization and key the cache by version fingerprint plus normalized retrieval parameters. + +## Patterns to Follow + +### Pattern 1: One application service, two transports + +**What:** REST controllers and MCP tools are thin adapters over `ProjectVersionService`, `BuildJobService`, and `ContextService`. + +**When:** For every new lifecycle or context operation. + +**Why:** It prevents REST and MCP from drifting into separate status semantics, access checks, and query paths. + +```python +# transport adapter shape; service owns authorization and domain policy +async def get_context(version_id: str, request: ContextRequest, principal: Principal): + return await context_service.retrieve( + version_id=version_id, request=request, principal=principal + ) +``` + +### Pattern 2: Version-scoped immutable artifacts + +**What:** Derive all source, manifest, and CPG locations from internal project/version IDs; write them once and treat ready snapshots as immutable. + +**When:** Upload, CPG generation, context source reads, deletion, retention. + +**Why:** A CPG and its citations must refer to the exact source snapshot an agent asked about. This also eliminates cross-version overwrite races caused by using source labels or unscoped hashes as paths. + +### Pattern 3: Durable state + durable job, with reconciliation + +**What:** Persist version lifecycle and job lifecycle separately but link them transactionally where possible; reconcile them at startup and in status reads. + +**When:** Queue admission, worker restart, explicit retry, worker failure, shutdown. + +**Why:** Existing queue recovery requeues `running` jobs after restart. The version state needs the same recovery story or public status can become permanently `building`/`queued`. + +### Pattern 4: Bounded, cited retrieval pipeline + +**What:** Compose symbols, lexical candidates, and graph expansion into a deterministic pipeline with a global item/token/byte budget. + +**When:** All AI-facing context responses. + +**Why:** This uses v0.6's CPG strength without making raw CPGQL an agent-facing authority, and keeps results inspectable and useful in a limited model context window. + +## Anti-Patterns to Avoid + +### Anti-Pattern 1: Treating an uploaded archive as a local source path + +**What:** Route archive contents into the current `source_type='local'` flow or pass caller paths to `CPGGenerator`. + +**Why bad:** It bypasses archive extraction controls and conflates client data with trusted host paths; on chat deployments, local source input is intentionally disabled. + +**Instead:** Add a distinct `archive` ingestion source that produces a server-owned, version-scoped snapshot before any build job is created. + +### Anti-Pattern 2: Rebuilding queue and Joern orchestration for REST + +**What:** Add a second REST worker loop, in-memory task, or direct Docker/Joern calls. + +**Why bad:** It defeats Postgres dedup/backpressure and Redis-global memory admission, creating duplicate builds and unaccounted JVM pressure. + +**Instead:** Adapt `DurableCPGQueue`/`CPGGenerator` through a build service; preserve the one active job and per-CPG memory model. + +### Anti-Pattern 3: Exposing raw paths, hashes, or CPGQL as the public context contract + +**What:** Let clients provide a CPG file path/hash or arbitrary CPGQL for context gathering. + +**Why bad:** Paths and hashes become confused authorization tokens, raw CPGQL remains only best-effort sandboxed, and citations lose a stable version identity. + +**Instead:** Resolve an authorized version ID inside `ContextService`; use fixed query templates and structured retrieval options. + +### Anti-Pattern 4: Extract-then-validate archives + +**What:** Use `extractall` and inspect results afterward. + +**Why bad:** Traversal links, special files, and decompression bombs have already crossed the filesystem/resource boundary. + +**Instead:** Validate each archive member and enforce cumulative caps before writing; extract only regular files through confinement checks. + +## Scalability Considerations + +| Concern | At 100 users | At 10K users | At 1M users | +|---|---|---|---| +| Uploads | Stream to local staging; enforce strict archive caps and bounded queue. | Move archives/staging to object storage or dedicated ingest volume; keep manifest in Postgres. | Separate authenticated upload service/object storage with malware scanning and quota accounting. | +| CPG builds | Existing Postgres queue, `build_workers`, cgroup cap, and memory budget are sufficient on the dedicated host. | Horizontally run workers only after version artifact storage is shared and job leases are robust. | Multi-node scheduler/tenant quotas; explicitly out of scope for v0.7. | +| Context reads | QueryExecutor auto-wake + Redis lock; cache compact per-version responses. | Read replicas/cache for metadata; prioritize/cancel queries and keep Joern pool admission global. | Precompute indexes/embeddings and shard artifacts/worker pools; vector-first retrieval remains deferred. | +| Storage | Version-scoped artifacts with retention/explicit delete; monitor CPG disk use. | Lifecycle policies and artifact GC; content-deduplicate only after correct authorization semantics. | Object storage, immutable manifests, legal retention and tenant deletion workflows. | +| Isolation | Single trust domain behind reverse-proxy auth; gate raw CPGQL. | Per-project authorization and worker mounts limited to one version. | True tenant isolation, network egress controls, separate credentials/control planes. | + +## Build Order + +1. **Foundation: catalog, IDs, migrations, and shared API shell.** Add project/version schema, repositories, state machine, authenticated REST routing, and an adapter boundary while preserving existing MCP operations. +2. **Secure ingestion.** Implement streamed archive staging, inspection/extraction, manifests, promotion/reconciliation, quotas, and deletion/retention semantics. No worker integration until the snapshot boundary is tested. +3. **Version build lifecycle.** Connect promoted versions to the existing durable queue and CPG generator; add version/job status and explicit retry behavior. Migrate existing `codebases` records through a compatibility mapping rather than breaking volumes. +4. **ContextService.** Implement fixed retrieval templates, version-confined source excerpts, citations, budgets, and REST/MCP adapters. Test ready/building/failed/sleeping versions and cache invalidation by version fingerprint. +5. **Hardening and operations.** Add auth enforcement, rate/size limits, audit-safe observability, storage GC, recovery tests, and Compose/deployment documentation. Consider stricter per-worker mounts and egress denial before any untrusted multi-project exposure. + +The order is deliberate: semantic context cannot cite reliably until immutable versions exist; versions cannot safely reach the queue until archive promotion is secure; REST/MCP parity is safest when both are only adapters over the finalized services. + +## Sources + +- [Project scope and v0.7 decisions](../PROJECT.md) — HIGH confidence +- [Current architecture](../../docs/architecture.md) — HIGH confidence +- [Threat model and residual risks](../../docs/security.md) — HIGH confidence +- [Runtime assembly and dependency startup](../../main.py) — HIGH confidence +- [Postgres catalog implementation](../../src/utils/postgres_db_manager.py) and [durable job store](../../src/utils/postgres_job_store.py) — HIGH confidence +- [Existing CPG lifecycle](../../src/tools/core_tools.py), [generator](../../src/services/cpg_generator.py), and [query execution](../../src/services/query_executor.py) — HIGH confidence + +## Architecture Research Gaps + +- The repository has no REST/auth framework or identity model today.

[HIGH] + +## Table Stakes + +Features users expect. Missing = product feels incomplete. + +| Feature | Why Expected | Complexity | Acceptance-oriented behavior / notes | +|---|---|---:|---| +| Authenticated archive submission | A backend receiving proprietary source must make ownership and ingress explicit. | High | `POST /projects/{project}/versions` accepts one allowed archive type over an authenticated interface; it returns `201` with immutable `project_id`, `version_id`, content digest, and a lifecycle URL. Reject missing identity, unsupported media type, malformed archive, over-limit compressed/uncompressed size, excessive file count, traversal paths, special files, or symlinks. Never expose an archive path or upload token in responses/logs. | +| Staged, canonical source snapshot | A version must be reproducible and safe to hand to a parser. | High | Extract into a per-upload temporary directory; validate every archive entry before copying to a final snapshot owned by `version_id`. Reject `..`, absolute paths, NUL/control characters, duplicate canonical paths, escaping symlinks, and files outside configured policy. Persist a manifest (relative path, byte size, SHA-256), source digest, detected/specified language, and ingest timestamps. Delete staging on success and failure. | +| Project and immutable version catalog | Agents must refer to the same code, even after another upload. | Medium | Create/list/read projects and versions. A version holds its source digest, manifest summary, CPG build ID/status, language/config, creation time, and parent/version label. A new upload never mutates an existing ready version; identical content for the same analysis configuration returns or references the existing version deterministically. | +| Asynchronous CPG build lifecycle | CPG construction is long-running and capacity-bound. | Medium | Submitting a version enqueues one durable build, returning without waiting. Status exposes a stable state (`queued`, `building`, `loading`, `ready`, `failed`), phase, queue position when queued, elapsed/deadline, retry count, and sanitized failure code/message. A duplicate submit does not start a second active build. `ready` only means a usable CPG exists, not merely that an archive was stored. | +| Retry and cancellation semantics | Users need a recoverable path after transient parser/worker failure. | Medium | An explicit retry creates/requeues work only for a terminal failed version and preserves attempt history; it does not overwrite a successful CPG. Interrupted running jobs are requeued on scheduler startup. Cancellation is allowed only before a worker begins parsing; it produces a terminal `cancelled` result and cleans partial CPG artifacts. (Cancellation requires a small extension beyond the current queue.) | +| Bounded context retrieval | Agents need direct answers, not raw graph dumps. | High | `POST /versions/{id}/context` requires a ready version and an explicit query/symbol; it returns a bounded response with a documented maximum item/byte/token budget, `truncated` when applicable, and no raw CPGQL. Each item includes `path`, start/end line, snippet, symbol (when known), and why it was selected. | +| Hybrid symbol, lexical, and graph expansion | Name lookup alone misses callers, callees, and data-flow-adjacent code. | High | Retrieval resolves exact/qualified symbols first; lexical search supplies candidates when symbols are absent; graph expansion adds a capped relationship neighborhood (for example callers/callees or relevant flow nodes). Rank and deduplicate passages, then fetch source spans. The response identifies which method(s) produced each item. Start without embeddings, as the project boundary specifies. | +| Source citations and version provenance | An agent must be able to inspect or quote retrieved code safely. | Medium | Every context response includes `project_id`, `version_id`, immutable digest, retrieval timestamp, and per-item citation stable within the version: relative path plus 1-based inclusive line range. A client can request a cited span only if it belongs to the version and configured maximum-span limits. | +| REST/MCP parity | Existing MCP users and backend clients need the same lifecycle concepts. | High | REST is the contract of record; thin MCP tools call the same application services and return the same IDs/status/citation schema. No endpoint/tool accepts host-local paths for public archive ingestion. Contract tests prove parity for upload/version status and context retrieval. | +| Tenant-bound authorization and audit trail | The current deployment is explicitly single-tenant with no built-in auth, which is insufficient for archive upload. | High | Authenticate every new REST/MCP lifecycle/context call; authorize project/version access before metadata, status, source span, or context is returned. Record actor, project/version, operation, outcome, request/correlation ID, and timestamp without raw source or credentials. v0.7 may implement one tenant/trust domain, but ownership checks must be in the service boundary so a later multi-tenant model is possible. | +| Quotas, backpressure, and observability | Parsing untrusted archives can exhaust disk, CPU, and memory. | Medium | Enforce upload/project quotas before finalization and return a typed retryable response for a full build queue. Expose version counters by lifecycle state, admission rejection reason, queue depth, build duration, retrieval latency, and truncation count. Operators can diagnose a failed build without receiving filesystem paths or sensitive source. | + +## Differentiators + +Features that set product apart. Not expected, but valued. + +| Feature | Value Proposition | Complexity | Notes | +|---|---|---:|---| +| Explainable CPG-grounded context | Makes agent context auditable: results show not only matching text but graph evidence such as call/data-flow relationships. | High | Return compact `relationship` evidence (`caller_of`, `callee_of`, `flow_adjacent`, etc.) next to citations. Keep traversal depth/result count capped and allow only approved relationship types. | +| Version-aware comparison context | Lets an agent reason about a regression or security change with stable inputs. | High | Retrieve the same symbol/path across two ready versions and cite both. Defer until the base catalog and one-version context contract are proven; it depends on snapshots, manifests, and stable citation format. | +| Retrieval coverage/quality signal | Helps agents know when a CPG may have parsed little or none of a project. | Medium | Surface user-method count, indexed-file count, excluded/unsupported file count, and a `partial_analysis` warning in version readiness and context responses. The backend already records a user-method count as a CPG coverage sanity check. | +| Deterministic retrieval profile | Makes CI and agent runs reproducible rather than relying on opaque ranking. | Medium | Persist a named retrieval profile/version (lexical fields, relationship types, caps) with each request/response. Same version + query + profile produces stable ordering where underlying CPG results are stable. | + +## Anti-Features + +Features to explicitly NOT build in v0.7. + +| Anti-Feature | Why Avoid | What to Do Instead | +|---|---|---| +| Unrestricted raw CPGQL for untrusted agents | Joern uses a Scala interpreter; the existing denylist is explicitly defense-in-depth, and raw queries can reach the shared playground. | Keep raw CPGQL internal/admin-only. Expose a curated ContextService with fixed, parameterized retrieval operations and hard output/traversal limits. | +| Embedding/vector-database-first retrieval | Adds an index, model, ingestion pipeline, and relevance failure modes before the product proves its lexical/CPG contract; it is out of scope in the project brief. | Build explainable symbol + lexical + graph retrieval first. Re-evaluate embeddings after recorded retrieval quality/latency data exists. | +| Mutable versions or “replace archive” | Invalidates citations, cached CPGs, reproducibility, and audit records. | Create a new immutable version for every distinct snapshot; mark or archive old versions through a separate lifecycle policy. | +| Git hosting, pull-request sync, web IDE, or full repository browser | Broadens the trust surface and competes with established SCMs; it does not advance upload-to-context. | Accept a bounded archive, retain a manifest, and return cited snippets only.

Archive extraction becomes a host filesystem primitive +**What goes wrong:** The service calls `extractall`, trusts member names or MIME/extension, follows symlinks/hardlinks, or writes before enforcing cumulative limits. A crafted archive can escape staging (`../` or absolute paths), overwrite files, create devices/FIFOs, or exhaust disk/CPU through compression bombs. Duplicate paths after Unicode/separator normalization can also cause manifest/CPG disagreement. +**Why it happens:** Archive libraries make extraction look atomic and archive metadata is mistaken for a security boundary. +**Consequences:** Source overwrite, secret disclosure, denial of service, poisoned CPGs, and citations that do not match the uploaded bytes. +**Prevention:** Stream to a server-generated mode-0700 staging directory; inspect every member before writing; accept regular files/directories only; reject absolute/traversal paths, links, special files, duplicate normalized names, excessive depth/count, compression ratio, per-file and total uncompressed limits. Compute a manifest and SHA-256 from the extracted snapshot, then atomically promote it under server-owned project/version IDs. +**Detection:** Alerts on extraction-limit rejections, unexpected filesystem entries, staging growth, orphan directories, and manifest/checksum mismatch. Fuzz ZIP/tar fixtures and restart during extraction in tests. +**Phase placement:** Secure ingestion (must precede any queue/Joern integration). + +### 2. Upload and CPG build are not one transaction +**What goes wrong:** Metadata is committed while promotion/enqueue fails, or a worker starts from a still-changing staging path. Conversely, a promoted source has no catalog row after a crash. +**Why it happens:** Postgres transactions cannot atomically include filesystem rename and Joern execution. +**Consequences:** Versions stuck forever in `building`, jobs pointing at deleted paths, duplicate builds, and irreproducible context citations. +**Prevention:** Use a recoverable two-step protocol: stage → validate/manifest → atomic rename to immutable final snapshot → commit catalog + durable job linkage; never expose staging to workers. On startup reconcile staging/final directories and catalog rows, mark incomplete versions repairable/failed, and garbage-collect only with an explicit ownership check. Keep one monotonic version state machine and idempotency key. +**Detection:** Reconciliation metrics (orphan bytes, versions without jobs, jobs without versions), invariant checks, and crash/restart fault-injection tests at every boundary. +**Phase placement:** Catalog foundation and ingestion; repeated in lifecycle hardening. + +### 3. Public API exposes paths, hashes, or raw CPGQL as authority +**What goes wrong:** Clients submit filesystem paths or CPG hashes that are accepted as identity, or REST context routes pass arbitrary CPGQL into Joern. Existing raw-query denylisting is defense-in-depth, not a sandbox. +**Why it happens:** Reusing v0.6 tool parameters is faster than introducing project/version authorization and fixed query templates. +**Consequences:** Cross-project reads, host-path traversal, query/code execution inside Joern, source/CPG disclosure, and unstable citations. +**Prevention:** Use opaque server-issued project/version IDs; resolve and authorize IDs inside `ContextService`; keep CPGQL behind admin/internal policy and named parameterized templates. Mount only version-specific artifacts where feasible, disable raw query for untrusted callers, and preserve timeout/row/output caps. +**Detection:** Security tests attempting path/hash substitution, IDOR across projects, Scala-string injection, and obfuscated raw-query escape; audit logs must record principal, version, template, and budget without source secrets. +**Phase placement:** API/auth foundation and context-service hardening. + +### 4. Queue state and Joern state diverge on crash, retry, or timeout +**What goes wrong:** A process restart requeues a `running` DB job but the version remains `building`; a late worker marks a retried job `ready`; automatic retries create concurrent CPG builds; a query timeout kills a loading server and corrupts an otherwise valid import. +**Why it happens:** Existing durable jobs and CPG tracker have separate state stores and timeout semantics. `FOR UPDATE SKIP LOCKED` prevents double claim, but does not provide a complete lease/fencing protocol. +**Consequences:** Duplicate expensive builds, stale CPG overwrites, permanent false failures, memory spikes, and status endpoints that lie. +**Prevention:** Add job attempt/lease or fencing token, version-scoped output paths, compare-and-set terminal transitions, and one-active-build uniqueness per version. Define bounded retry/backoff versus terminal failure, cancellation semantics, and worker shutdown behavior. Treat `LOADING/GENERATING` specially in query timeout handling; never kill an import merely because a query deadline elapsed. +**Detection:** Metrics for stale leases, late completions, duplicate attempts, and state invariant violations; integration tests for crash-after-claim, timeout-during-load, retry races, and Compose redeploy. +**Phase placement:** Version build lifecycle, then operations hardening. + +### 5. Resource admission is bypassed by uploads or parallel jobs +**What goes wrong:** Upload limits cover bytes but not number of queued builds, extracted file count, disk occupancy, or total CPG memory. A REST worker loop or per-request task bypasses the existing Postgres queue, Redis lock, cgroup caps, and backpressure. +**Why it happens:** HTTP responsiveness encourages fire-and-forget tasks; queue depth is mistaken for total resource control. +**Consequences:** Disk exhaustion, Postgres connection pressure, Joern OOM, host instability, and noisy-neighbor starvation. +**Prevention:** Reuse `DurableCPGQueue`, enforce admission before staging and enqueue, cap per-principal/project bytes and active jobs, reserve disk, and surface `202`/`429`/`503 queue_full` explicitly. Keep build worker concurrency and heap within the configured Joern memory budget; rate-limit retrieval as well as uploads. +**Detection:** Monitor staging bytes, queue age/depth, CPG disk usage, RSS/heap, Postgres pool saturation, and rejection reasons. Load-test worst-case archive/build mixes. +**Phase placement:** Ingestion quotas and lifecycle/operations hardening. + +## Moderate Pitfalls + +### 6. Version identity is mutable or content hashing is incomplete +Changing a label, source root, ignored files, frontend flags, or generated overlays without changing the fingerprint can reuse the wrong CPG. Hash the canonical manifest plus build options; make ready artifacts immutable and key caches by version fingerprint and authorization scope. + +### 7. Authentication is added only to REST or only to MCP +FastMCP's mounted ASGI app requires the MCP lifespan to be passed to the host FastAPI app for session management; middleware state must be consistently propagated. Protect both transports with the same principal/scope checks, reject missing/invalid credentials, and test direct mounted paths and WebSocket/streaming variants. (FastMCP official docs, HIGH: https://github.com/prefecthq/fastmcp/blob/main/docs/integrations/fastapi.mdx) + +### 8. Error/status contract leaks internals or hides lifecycle state +Returning `connection refused`, host paths, Joern stderr, or raw exception text leaks deployment details; returning generic `500` for `queued`, `building`, `sleeping`, and `failed` makes agents retry incorrectly. Define stable DTOs and error codes (`queued`, `building`, `ready`, `failed`, `queue_full`, `version_not_ready`), redact paths/secrets, include retry hints and correlation IDs. + +### 9. Source cleanup invalidates citations or future reactivation +The current configuration can delete ephemeral source after CPG generation, while context responses need source excerpts and citations. Retain an immutable snapshot (or a separately durable, checksummed excerpt store) until retention/deletion policy permits removal; do not run CPG GC as if it were source retention. + +### 10. Retrieval returns plausible but incorrect context +Lexical hits can outrank exact symbols; graph expansion can explode; stale CPGs can be queried after a version update; truncation can silently remove the evidence an agent needs. Use deterministic tiering (exact symbol/file → lexical → bounded graph), deduplication, global byte/item/token budgets, explicit `truncated`, and citations carrying version ID, repo-relative path, line range, and reason. Cache only with normalized query/options + version fingerprint. + +### 11. Cross-version and cross-principal cache contamination +Caching by query text or legacy codebase hash alone can serve another version or tenant. Include immutable version fingerprint, retrieval options, and principal authorization scope in cache keys; re-authorize on cache hits and invalidate on deletion. + +### 12. Language/frontend and repository edge cases are treated as generic failures +Joern frontends differ in flags, generated/ignored files, compile databases, and supported languages. Auto-detection can produce empty or misleading CPGs. Persist detected language, frontend/options, manifest statistics, and a sanitized build diagnostic; validate unsupported/ambiguous uploads before enqueue and expose a clear `unsupported_language`/`empty_cpg` state. + +## Minor Pitfalls + +### 13. Filename and path normalization differs between manifest, DB, and citations +Normalize separators, Unicode, case policy, and newline handling once; store repository-relative POSIX paths and use the same canonicalizer for extraction, hashing, source reads, and response citations. + +### 14. Retention/GC races with active queries +Deleting a version while a Joern query or source read is active yields missing-file errors or dangling citations. Mark `deleting`, block new work, wait for active references/jobs, then remove artifacts; make deletion idempotent and auditable. + +### 15. Observability records sensitive source data +Logging archive names, tokens, source snippets, full queries, or Joern errors can exfiltrate secrets. Log IDs, sizes, hashes, state transitions, bounded error classes, and correlation IDs; apply redaction before structured logs and traces. + +### 16. API retries create accidental duplicates +Clients retry timeouts and receive a second version/job. Require an idempotency key for upload/build submission, enforce unique `(project, content_sha256)` and active-job constraints, and return the existing resource with a duplicate indication. + +## Phase-Specific Warnings + +| Phase topic | Likely pitfall | Mitigation | +|---|---|---| +| Catalog/API foundation | IDOR, mutable identities, REST/MCP drift | Opaque IDs, principal scope on every repository query, shared application services and DTO/error contract | +| Secure archive ingestion | Traversal, links, bombs, disk exhaustion | Pre-extraction inspection, regular-file-only extraction, cumulative limits, private staging, manifest/checksum, quotas | +| Async CPG lifecycle | Duplicate/stale workers and split-brain status | Durable queue reuse, leases/fencing, CAS state transitions, version-scoped outputs, startup reconciliation, bounded retries | +| Context retrieval | Wrong/stale evidence, graph/result explosion, source unavailable | Immutable retained snapshots, deterministic hybrid ranking, bounded templates/budgets, explicit truncation and citations | +| Auth/deployment hardening | Docker socket/root-equivalent host compromise; unauthenticated endpoint | Dedicated host, reverse-proxy/mTLS/JWT, same auth on REST+MCP, disable/gate raw CPGQL, restrict Joern mounts/egress | +| Operations/retention | GC races and unbounded storage | Separate source/CPG retention, active-reference draining, artifact accounting, orphan reconciliation and alerts | + +## Sources + +- [Project scope, constraints, and key decisions](../PROJECT.md) — HIGH +- [Repository threat model and existing controls](../../docs/security.md) — HIGH +- [Architecture integration seams and lifecycle proposal](./ARCHITECTURE.md) — HIGH for repository facts; MEDIUM for proposed contract +- [Durable Postgres job store](../../src/utils/postgres_job_store.py) — HIGH +- [QueryExecutor timeout/lock/auto-wake behavior](../../src/services/query_executor.py) — HIGH +- [FastMCP FastAPI integration and lifespan](https://github.com/prefecthq/fastmcp/blob/main/docs/integrations/fastapi.mdx) — HIGH (Context7-verified 2026-08-09) +- [FastMCP middleware request state](https://github.com/prefecthq/fastmcp/blob/main/docs/servers/middleware.mdx) — HIGH (Context7-verified 2026-08-09) + +## Research Gaps + +- Exact archive formats, limits, malware-scanning requirement, retention duration, and tenant/auth provider remain product decisions. +- Joern version-specific frontend behavior and CPG serialization compatibility should be checked during the lifecycle phase against the pinned image/version. +- The repository has no current REST identity model; authentication, authorization, and mounted FastMCP routing need phase-specific design and integration tests. diff --git a/.planning/research/STACK.md b/.planning/research/STACK.md new file mode 100644 index 0000000..f61a33e --- /dev/null +++ b/.planning/research/STACK.md @@ -0,0 +1,109 @@ +# Technology Stack + +**Project:** CodeBadger v0.7 — Codebase Context Backend +**Researched:** 2026-08-09 +**Scope:** Backend stack additions only; this recommendation preserves the deployed Python/FastMCP/Joern/Postgres/Redis/Docker Compose architecture. + +## Recommended Stack + +### Core Framework + +| Technology | Version | Purpose | Why | +|---|---:|---|---| +| Python | 3.13 (already deployed) | Application runtime | Supports the existing service code and current standard-library archive safety APIs.

Before implementation, resolve and lock the FastAPI/FastMCP compatible versions together in a reproducible constraints/lock file; the repository currently records ranges, not a lockfile. + +## Security and Archive-Handling Requirements + +1. Support ZIP only for the first contract. Reject encrypted archives, unsupported compression methods, duplicate normalized paths, absolute paths, `..` traversal, device/FIFO entries, symlinks/hardlinks, and ambiguous Unicode/control-character names. +2. Apply limits before and during extraction: request `Content-Length` if present, streamed compressed-byte cap, maximum member count, per-member uncompressed cap, total uncompressed cap, path-depth cap, and compression-ratio cap. Do not trust the filename or MIME type. +3. Extract member-by-member to a mode-`0700` staging directory using canonical destination checks; do not use `extractall()`. Hash the received archive and produce a deterministic source manifest before enqueueing work. +4. Make upload idempotency explicit: a client idempotency key and/or `(project_id, archive_sha256)` unique constraint must return the existing version/job rather than enqueueing another CPG build. +5. Authenticate all `/v1/*` endpoints with a FastAPI dependency. For v0.7, use one configured opaque bearer token checked with `secrets.compare_digest` (or an already-managed reverse-proxy identity); do not claim user/tenant authorization before a real identity model exists. Put the mounted MCP path behind the same perimeter/auth policy. Keep `/health` unauthenticated only if it exposes no sensitive details. + +## Alternatives Considered + +| Category | Recommended | Alternative | Why Not | +|---|---|---|---| +| REST facade | FastAPI outer app + mounted FastMCP | FastMCP custom routes only | FastMCP documents custom health routes as deliberately outside its authentication middleware; authenticated REST endpoints belong in FastAPI’s dependency model. | +| Background jobs | Existing Postgres durable queue | Celery/RQ/Dramatiq | The current queue already has DB durability, deduplication, restart recovery, backpressure, and multi-worker-safe claims. Another queue creates split status and retry truth. | +| Archive format | ZIP-only + stdlib validation | ZIP + TAR + 7z from day one | More parsers and link semantics multiply the attack surface. Add TAR only after archive policy tests cover it; do not accept 7z in v0.7. | +| Indexing | PostgreSQL FTS + `pg_trgm` + Joern | Elasticsearch/OpenSearch | A separate search cluster is unjustified before corpus scale or relevance needs demonstrate it; PostgreSQL keeps version/citation consistency transactional. | +| Semantic retrieval | Lexical + symbols + bounded CPG links | Embeddings/vector database | The milestone explicitly defers embedding-first retrieval. Graph relationships supply structural context while lexical ranking remains inspectable. | +| Data layer | psycopg repositories + SQL migrations | SQLAlchemy/Alembic introduction | The project is already psycopg-based. A thin migration runner and focused repositories minimize a broad persistence rewrite during a contract-establishing milestone. | + +## Implementation Notes and Version Risks + +- `main.py` currently calls `mcp.run_http_async()` and exposes only FastMCP custom routes. Replace that boot path with a combined ASGI app: create `mcp.http_app(path="/mcp")`, create a FastAPI app with the combined lifespan, and mount/include the MCP routes. Preserve the existing concurrency limiter around both publicly reachable facades, with a separate upload byte/concurrency limit if necessary. +- The current jobs schema has only `queued/running/done/failed`, JSON stored as `TEXT`, and requeues every `running` job at startup. It is sufficient for builds but needs an explicit retry policy (`max_attempts`, retryable error classification, next-at/lease metadata) before exposing retries as an API guarantee. That is a schema migration, not a queue-framework switch. +- Current codebase catalog keys only by hash. v0.7 needs a stable `project_id` and immutable `version_id`, so two projects can intentionally reference identical content without collapsing their catalog history. Keep content SHA/CPG cache keys as deduplication artifacts, not as the public version identity. +- Source indexing must run only on the validated promoted snapshot and must store file/line ranges that remain correct for that immutable version.
