From 015bec367e5a4883ff911ecf3d6f0efaccdfe87a Mon Sep 17 00:00:00 2001 From: Number531 <120485065+Number531@users.noreply.github.com> Date: Thu, 16 Apr 2026 11:31:35 -0400 Subject: [PATCH 01/27] =?UTF-8?q?obs(w1):=20docs=20=E2=80=94=20observabili?= =?UTF-8?q?ty=20planning=20+=20impl=20spec=20baseline?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Baseline the Wave 1 reference documents on observability/wave-1 before implementation begins. - observability-updates-april-26.md — scoping, retrofit-cost roadmap (4 waves), per-item complexity/break-risk/time ratings, acceptance criteria, explicit out-of-scope. - observability-implementation-spec.md — granular per-module spec: file paths, function signatures, NDJSON row schemas, test matrices, rollout plan, cross-wave concerns (feature flags, env vars, alerts, DR runbook), module dependency graph. Wave 1 scope (to follow in subsequent commits): #3 raw-source archive (Path B: session-dir + global pool + per-agent manifests) #8 prompt-injection detection on tool outputs #12 per-tool latency histograms (P50/P95/P99) #13 per-API 7-day SLA dashboard All four items gated behind feature flags defaulting to false. Module decomposition + NDJSON schema versioning bundled day-one to avoid disproportionate retrofit cost later.

Planning / pre-implementation +**Context**: Gap analysis against institutional-buyer observability requirements (PE / IB / M&A / hedge fund / IC). Most original Tier-1 items from the audit collapsed once the single-tenant-per-MD architecture, Docker-versioned reproducibility, and certification-layer citation provenance were confirmed. Four items survive. + +**Revision note (2026-04-16)**: +- **#3 redesigned to "Path B"** — session-directory + global content-addressed pool + per-agent manifest view, replacing the original `source_documents` DB-backed approach. Leverages the existing `document_ready` pattern and `reports/{session_id}/` convention. Zero new DB tables in the initial ship; kg_provenance FK and `kg_node_provenance` link table deferred to Wave 3. +- **Added: Enterprise Readiness Roadmap** (P0/P1/P2) with retrofit-cost analysis — only one P0 item (module decomposition) is bundled into initial ship; everything else is safely deferrable at single-MD scale. +- **Revised shipping sequence into 4 waves** with explicit gates between them. + +--- + +## Scope Summary (revised) + +| # | Item | Complexity | Break Risk | Time | Priority | +|---|------|-----------:|-----------:|-----:|----------| +| 3 | Raw-source archive (Path B: session-dir + global pool + per-agent manifests) | **1/5** | **1/5** | **5–7h** | Tier 1 | +| 8 | Prompt-injection detection on tool outputs | 2/5 | 1/5 | 4–6h (Phase 1) + 2–3h (Phase 2) | Tier 2 | +| 12 | Latency histograms per tool (P50/P95/P99) | 2/5 | 1/5 | 3–4h | Tier 2 | +| 13 | 7-day SLA dashboard per external API | 3/5 | 2/5 | 6–8h | Tier 2 | + +**Wave 1 combined estimate**: 18–25 engineer-hours. +**Full roadmap including Waves 2–4 (enterprise hardening)**: ~60–80 engineer-hours across 3–4 months. + +--- + +## Enterprise Readiness Roadmap + +After architectural review (2026-04-16), the core design satisfies most enterprise principles by construction (single source of truth, immutability, idempotency, separation of concerns, loose coupling, DRY, data lineage). Gaps between "well-designed" and "enterprise-deployed" were catalogued and assessed by **retrofit cost**. The principle: do items whose retrofit cost is high on day one; defer items whose retrofit cost is linear or low. + +### Retrofit-cost scorecard + +| Item | Retrofit cost | Disposition | +|---|---|---| +| **P0 #1 — WAL + reconciliation** | Low | **Defer to Wave 3.** Correct write ordering (pool body → metadata → manifest → index → DB) makes orphan files benign. WAL becomes necessary when multiple cross-system atomic writes exist — not the case today. | +| **P0 #2 — Error taxonomy** | Low | **Defer to Wave 3.** Retrofit via find-and-replace. Typed errors replace strings without touching call sites. | +| **P0 #3 — Module decomposition** | **HIGH** | **Bundled into Wave 1.** Building modular from day one adds ~2 hours; refactoring a monolithic `rawSourceService.persist()` later costs 20–30 hours plus production review latency. | +| **P0 #4 — Migration tool (node-pg-migrate)** | Medium | **Adopt at Wave 2 second schema change**, not now. Retrospectively version existing DDL as `001_initial`. Avoids paying introduction cost for a single-schema codebase. | +| **P1 #5 — Access audit log** | Low | **Wave 3.** New table + middleware. Zero coupling to existing paths. | +| **P1 #6 — Retention classes + tombstone** | Low-Medium | **Wave 3.** Add columns to existing tables; erasure workflow is new code. | +| **P1 #7 — DR / RPO-RTO / GCS tiering** | Medium | **Wave 3.** Bodies already dedup by hash; tier daemon is additive. | +| **P1 #8 — OpenTelemetry distributed tracing** | Medium | **Wave 3.** `@opentelemetry/api` instrumentation is additive, but touching many files — batch with Wave 3 hardening. | +| **P1 #9 — Capacity + backpressure** | Low | **Wave 3.** Guard clauses on queue depth + pool writes. | +| **P2 #10 — Multi-region readiness** | Medium | **Wave 4.** Schema supports region columns from Wave 3 onward; activate when EU client needs it. | +| **P2 #11 — NDJSON schema versioning** | **LOW (free)** | **Bundled into Wave 1.** Every manifest row includes `"schema_version": 1`. Costs nothing, avoids future parse ambiguity. | +| **P2 #12 — Embedding model versioning** | Low | **Wave 2.** `embedding_generation` column added with the embedding table. | +| **P2 #13 — Cost ledger per session** | Low | **Wave 4.** Tag metadata with session_id; aggregation job is new code. | +| **P2 #14 — Testing discipline mandate** | Ongoing | **Applied from Wave 1.** Each module gets unit tests; integration test per wave; chaos test at Wave 3. | + +### Day-one enterprise baseline (bundled into Wave 1) + +Two items from the P0/P1/P2 list ship with the initial scope because deferring them is disproportionately expensive: + +1. **Module decomposition** (from P0 #3) — the rawSourceService work is split across 7 files from the start: + ``` + src/utils/rawSource/ + ├── SourceHasher.js (pure fn: canonicalize + SHA-256, ~40 LOC) + ├── SourceSanitizer.js (pure fn: secret scrubbing, ~60 LOC) + ├── SourceStorage.js (tier-aware pool read/write, ~80 LOC) + ├── SourceManifestWriter.js (session + per-agent NDJSON manifests, ~60 LOC) + ├── SourceIndexWriter.js (global _index.ndjson with fsync, ~40 LOC) + ├── SourceEmbeddingDispatcher.js (queue stub; real queue in Wave 2, ~20 LOC) + └── index.js (RawSourceService orchestrator, ~30 LOC) + ``` + Each module is pure or narrowly scoped, independently unit-testable, and has a single responsibility. Hexagonal / ports-and-adapters discipline from day one. + +2. **Schema versioning on manifest NDJSON** (from P2 #11) — every row in `raw-sources.ndjson`, `sources.ndjson` (per-agent), and `_index.ndjson` includes `"schema_version": 1`. Parser dispatches on version from day one. Free future-proofing. + +--- + +## Wave 1 — Initial Ship (~18–25 hours) + +Goal: deliver all four observability items behind feature flags, modular by construction, with the architectural baseline that makes Wave 2–4 additive rather than rewriting. + +### #3 — Raw-Source Archive (Path B) + +#### Goal +Persist every raw external API response (SEC filings, CourtListener opinions, Exa results, PTAB, EPO, etc.) as content-addressed files in a **global session-directory pool**, with a **per-agent manifest view** that makes each subagent's evidence auditable from the filesystem. Mirrors the existing `document_ready` SSE pattern on the ingress side. + +#### Architecture + +**Physical storage (global content-addressed pool):** +``` +reports/ +├── _sources/ ← Global pool, content-addressed, immutable, dedup'd +│ ├── ab/ ← 2-char shard on hash[0:2] +│ │ └── cd/ ← 2-char shard on hash[2:4] +│ │ └── abcd...ef.html.gz ← SHA-256-named, zlib-compressed +│ ├── meta/ +│ │ └── abcd...ef.json ← fetch metadata sidecar (url, tool, fetched_at, content-type) +│ └── _index.ndjson ← append-only global index (tamper-evident) +│ +└── {session_id}/ + ├── specialist-reports/ + │ ├── legal-researcher-report.md + │ ├── legal-researcher-sources/ ← logical view (~1–5 KB) + │ │ └── sources.ndjson ← rows: {schema_version, hash, display_name, url, fetched_at, tool, tool_use_id} + │ ├── financial-analyst-report.md + │ ├── financial-analyst-sources/ + │ │ └── sources.ndjson + │ └── ... + ├── raw-sources-manifest.ndjson ← session-level roll-up (all hashes consumed this session) + └── ... (existing section-reports/, review-outputs/, qa-outputs/) +``` + +**Presentation model (separated from storage):** +- Filesystem stores bytes **once** in the global pool — same SEC 10-K fetched across 50 deals = 1 file. +- Per-agent `sources.ndjson` manifests give auditors the "open the folder, see the analyst's evidence" UX with zero byte duplication. +- `/api/sessions/{sid}/agents/{agent}/bundle.zip` endpoint assembles per-agent audit bundles on demand. + +#### Integration points + +1. **New module: `src/utils/rawSource/`** — 7 files as shown in Day-One Baseline above. +2. **`src/utils/hookSSEBridge.js` — PostToolUse block** (~line 269): wire `RawSourceService.persist()` for `fetch_document`, `exa_web_search`, and future raw-source-carrying tools. Use existing `agentTypeMap` correlation from `agentStreamHandler.js` to attribute each capture to its originating subagent. +3. **`src/server/claude-sdk-server.js`** — new routes: + - `GET /api/raw-sources/:hash` → decompressed body (streaming, Content-Type from meta) + - `GET /api/raw-sources/:hash/meta` → fetch metadata JSON + - `GET /api/sessions/:sid/raw-sources` → session manifest (existing `/api/reports` pattern) + - `GET /api/sessions/:sid/agents/:agent/sources` → per-agent manifest +4. **SSE event addition** — `raw_source_ready` with `{ hash, size, url, tool_name, agent_id, dedup }` emitted on each capture. Frontend `#rawLog` (app.js:571) already captures this via `addRaw(e)` — zero frontend changes required. +5. **No DB tables in Wave 1.** `kg_node_provenance` and `source_chunk_embeddings` are Wave 2/3. +6. **No BaseHybridClient changes.** PostToolUse hook is the single chokepoint. + +#### Write pipeline (per PostToolUse fire, inside `setImmediate`) + +``` +1. Allow-list filter: fetch_document | exa_web_search | (extensible) +2. Extract body from tool_response.content[0].text +3. Size guard: body.length < MAX_RAW_BYTES (default 10 MB) +4. Canonicalize (SourceHasher): trim/collapse whitespace for text +5. hash = sha256(canonicalized) +6. Dedup check: fs.existsSync(poolPath(hash))? + ├── HIT → skip write, append to session + agent manifests only + └── MISS → sanitize → compress → atomic write (.tmp + rename) + → write meta sidecar → append to _index.ndjson + → append to session + agent manifests + → enqueue embedding (Wave 2 activates this) +7. Emit raw_source_ready SSE +``` + +**Invariants:** +- Atomic writes (write `.tmp` + `rename()` — readers never see partial files) +- Idempotent replay — same `(session_id, agent_id, hash)` on retry = no-op +- Fire-and-forget — all steps in `setImmediate`, never blocks hook chain +- Integrity check on every read — recompute SHA, compare to filename +- Append-only `_index.ndjson` and manifests — O_APPEND only at OS level where possible + +#### WORM / retention (Wave 1 interim) + +- **Wave 1**: filesystem `chmod 555` on `_sources/` after write; revoke write permission for the app user except via the write path. Weak legal grade; defensible for internal audit. +- **Wave 3**: GCS Object Lock migration + lifecycle daemon (hot 90d → warm GCS Standard 1y → cold Coldline 7y). + +#### Ratings + +- **Complexity**: **1/5** — filesystem writes, NDJSON appends, SHA-256, zlib. No DB, no base-class wrapping. +- **Break risk**: **1/5** — single insertion point in hookSSEBridge; fire-and-forget; already-proven pattern (`document_ready`). +- **Time estimate**: **5–7 hours** + - 2h module decomposition + implementation (7 files) + - 1h hookSSEBridge wiring + - 1h API routes + - 1h unit tests per pure module (Hasher, Sanitizer) + - 1h integration test (session run produces pool files + manifests) + - 1h docs + +#### Open questions + +- **Dedup scope**: global by hash alone. Same 10-K fetched twice = one file in pool. Per-session attribution via manifest file. +- **Compression threshold**: all text/JSON via zlib; skip PDFs/PNGs (already compressed). +- **Sanitizer patterns**: start with `Authorization:` / `api[-_]?key=` / AWS-keys / JWTs; extensible. +- **MAX_RAW_BYTES**: 10 MB default; log metadata-only stub for oversized responses. +- **Schema version**: all NDJSON rows include `"schema_version": 1` (free future-proofing). + +--- + +### #8 — Prompt-Injection Detection on Tool Outputs + +#### Goal +When an external response contains adversarial instructions (`[SYSTEM]`, `<|im_start|>`, explicit "SYSTEM:" with colon, hostile markdown/XML), detect it and write a new `event_type='PromptInjectionDetected'` row to `hook_audit_log`. **Detection + logging only in Phase 1 — no hard block.** Escalation to block can come after FP-rate calibration. + +#### Architecture — what exists today +- **Best interception point**: `postToolUseHandler` at `sdkHooks.js:993–1162`. Already parses `_hybrid_metadata` (lines 1018–1031) — perfect place to add detection. +- **Existing input-side regex patterns**: `middleware/inputValidation.js:1–46` has (`/ignore (previous|all|above) (instructions|prompts)/i`, `/\[SYSTEM\]/i`, `/<\|im_start\|>/i`). **Reuse, do not modify.** +- **Event-type flexibility**: `hook_audit_log.event_type` is `VARCHAR(50)` with no enum constraint. + +#### Integration points +1. **New file: `src/utils/promptInjectionDetector.js`** (pure module) — exports `detectInjection(text, context)` returning `{ detected: bool, confidence: number, patterns: string[], excerpt: string }`. +2. **`sdkHooks.js:1018–1031`** — inside existing `_hybrid_metadata` parse block, add detection call and emit `PromptInjectionDetected` event_type when triggered. +3. **No schema change** — `hook_audit_log` handles the new event type via existing `persistAuditEvent`. +4. **No frontend change in Wave 1** — silent DB logging. Frontend timeline marker is Wave 3 polish. + +#### Ratings +- **Complexity**: **2/5** — single pure module + one insertion point. +- **Break risk**: **1/5** — additive, inside existing try/catch. +- **Time estimate**: **4–6 hours** (Phase 1). Phase 2 (Haiku verification) +2–3h, any time later. + +#### Open questions +- **FP rate**: target regex on formatting tokens (`[SYSTEM]`, `<|im_start|>`, `SYSTEM:` with colon), not semantic phrases. Expect 15–20% FP on legal docs — acceptable for logging-only. +- **Scan length**: first 16 KB of tool response. +- **Haiku cost at Phase 2**: $0.005–0.02/session — acceptable. + +--- + +### #12 — Latency Histograms per Tool (P50/P95/P99) + +#### Goal +Emit P50/P95/P99 latency histograms labeled by `tool_name` and `client` (`directFetch`, `exa_fallback`, etc.).

This is the prerequisite. + +#### Integration points +1. **`src/utils/hookDBBridge.js` persistAuditEvent (~line 530–560)** — extract and merge fetch metadata into `event_data` JSONB. **Highest-risk change in Wave 1** (hot PostToolUse path); feature-flagged via `SLA_TELEMETRY=true`. +2. **`src/db/postgres.js`** — composite index shared with #12. +3. **`src/server/dbFrontendRouter.js`** — new route `GET /api/analytics/sla/7day`. +4. **`test/react-frontend/app.js` + `index.html`** — new SLA panel with 60s polling. + +#### Ratings +- **Complexity**: **3/5** — coordinated changes across hook, SQL, frontend. +- **Break risk**: **2/5** — hot-path change, mitigate with feature flag + try/catch. +- **Time estimate**: **6–8 hours**. + +--- + +## Wave 2 — Extended Archive + Migration Discipline (~12–15 hours, weeks 2–3) + +Kicks in when the observability value of Wave 1 is confirmed in production. Adds the DB-backed provenance chain that makes "claim → source chunk → bytes" queryable end-to-end. + +### Scope +1. **Adopt `node-pg-migrate`** (P0 #4) — retrospectively version existing schema as `001_initial_schema`, lock in migration discipline for all future DDL. One-time adoption cost ~2 hours. +2. **`source_chunk_embeddings` table + HNSW index** — chunks from the global pool, embedded via Gemini (`RETRIEVAL_DOCUMENT`, 3072 dims). Activates `RAW_SOURCE_EMBEDDING=true` flag. +3. **Chunking strategy per content type** — SEC filings by `Item NA` section headers, court opinions by paragraph (4K cap), Exa results 1-per-result, JSON by field-path.

No side effects, no I/O, trivially unit-testable. Design change from earlier spec draft: **no canonicalization**. The earlier spec specified text canonicalization (trim + collapse whitespace) before hashing, to improve dedup hit rate when the same document is re-fetched with trivial whitespace differences. That was rejected in favor of byte-exact audit fidelity: - stored bytes == API response bytes (modulo secret sanitization, a legitimate security transform auditors accept) - recomputing SHA-256 on a pool file matches the filename directly - an auditor can re-fetch from the API and compare bytes without having to replicate any canonicalization pipeline - realistic dedup loss is small — HTTP responses for the same URL from the same client tend to be byte-stable HashResult shape simplified: { hash, bytes, size, inferredContentType }. Content-type sniff (html/json/xml/text/binary) is informational only — drives filename extension, never mutates bytes. Spec updates in the same commit: - observability-implementation-spec.md §1.1.1 — Option B design note - observability-updates-april-26.md — write-pipeline step ordering (sanitize precedes hash; no canonicalize step) - module summary tagline updated Tests: 27 pass in 91ms under NODE_OPTIONS=--experimental-vm-modules jest. Covers: determinism, whitespace-different-inputs-different-hashes, byte-exact storage, filename-integrity (recomputed SHA matches), content-type sniffing (incl. binary NUL detection), input validation (TypeError on null/undefined/number/object), empty input, 1 MB performance (<50 ms).

Bundled into one commit because they share design discipline (append-only, parent-dir- on-demand, schema-version-agnostic). SourceManifestWriter — per-session and per-agent manifests: appendSession(sessionId, row) → {sessionsRoot}/{sessionId}/raw-sources-manifest.ndjson appendAgent(sessionId, agentType, row) → {sessionsRoot}/{sessionId}/specialist-reports/{agentType}-sources/sources.ndjson - Path traversal guard: agentType matches /^[a-z0-9][a-z0-9_-]*$/i (rejects '..', absolute paths, spaces). - Writer is intentionally dumb — does NOT validate row shape. schema_version presence and field correctness are the orchestrator's responsibility. - Uses fs.appendFile (Node O_APPEND under the hood) — concurrent appends from the same process produce well-formed NDJSON. SourceIndexWriter — global tamper-evident _index.ndjson: append(row) → {poolDir}/_index.ndjson - Per-call: open(a) + write + fsync + close. - The fsync per row is the difference from manifests: tail entries cannot be lost on crash. Cost is acceptable because append() only fires on dedup miss (new hash landings are rare). - Future Wave 3 hook: nightly Merkle root over this file becomes the tamper-evident anchor. Tests: 23 pass (12 manifest + 11 index) in 272ms against real temp dirs. Manifest: - factory validation, exposed surface - session path / agent path correctness - parent-directory creation on first append - strict NDJSON (one object per line, newline-terminated) - rich row shapes round-trip - path-traversal rejection ('../etc/passwd', '/abs', 'name with space') - safe agent-type acceptance (alphanum, hyphen, underscore, mixed case) - 10 parallel appendSession → 10 well-formed rows, all values present Index: - factory validation, indexPath exposed - single-row + multi-row ordering - poolDir creation on demand - strict JSON lines (no array wrapper, no trailing comma, newline-terminated) - rich row shapes round-trip (incl. nested objects) - 20 parallel appends → 20 distinct well-formed rows Co-Authored-By: Claude Opus 4.6 (1M context) --- .../src/utils/rawSource/SourceIndexWriter.js | 53 ++++++ .../utils/rawSource/SourceManifestWriter.js | 69 ++++++++ .../sdk/rawSource/SourceIndexWriter.test.js | 101 ++++++++++++ .../rawSource/SourceManifestWriter.test.js | 154 ++++++++++++++++++ 4 files changed, 377 insertions(+) create mode 100644 super-legal-mcp-refactored/src/utils/rawSource/SourceIndexWriter.js create mode 100644 super-legal-mcp-refactored/src/utils/rawSource/SourceManifestWriter.js create mode 100644 super-legal-mcp-refactored/test/sdk/rawSource/SourceIndexWriter.test.js create mode 100644 super-legal-mcp-refactored/test/sdk/rawSource/SourceManifestWriter.test.js diff --git a/super-legal-mcp-refactored/src/utils/rawSource/SourceIndexWriter.js b/super-legal-mcp-refactored/src/utils/rawSource/SourceIndexWriter.js new file mode 100644 index 000000000..3785d1a26 --- /dev/null +++ b/super-legal-mcp-refactored/src/utils/rawSource/SourceIndexWriter.js @@ -0,0 +1,53 @@ +/** + * SourceIndexWriter — global tamper-evident `_index.ndjson` with fsync discipline. + * + * Distinct from SourceManifestWriter because: + * - The global index records every NEW hash that lands in the pool (one row, + * ever, per hash) — used for nightly Merkle-root summarization (Wave 3). + * - Each append is fsynced so a crash cannot lose tail entries. + * + * Per-call cost: open + write + fsync + close.

charset=UTF-8 Content-Transfer-Encoding: 8bit Sixth of seven modules under src/utils/rawSource/. Intentionally minimal: preserves the interface the orchestrator will call so RawSourceService can `dispatcher.enqueue(hash, sourceType)` unconditionally — no branching on a feature flag for an absent real implementation. Wave 2 replaces this stub with: - bounded worker pool (BATCH_SIZE=20, MAX_DEPTH=500) - dedup check against source_chunk_embeddings (no re-embed) - chunkContent → embedDocuments (Gemini RETRIEVAL_DOCUMENT) - transactional INSERT into source_chunk_embeddings table - flag: RAW_SOURCE_EMBEDDING (default false) Wave 3 adds: - backpressure: shed-work above MAX_DEPTH, log + metric - per-error counter via raw_source_errors_total - circuit breaker on consecutive failures Stub is fail-open by design: enqueue() always resolves, never rejects. The orchestrator's `.catch(err => console.warn(...))` is defensive — the stub gives nothing to catch. No new tests — single async function returning undefined; full behavior tested via the RawSourceService orchestrator integration test in the next commit.

Composes the six preceding modules into a single fire-and-forget persist() call that the PostToolUse hook will invoke for raw-source-carrying tools. Pipeline (per persist() call): 1. Validate input (graceful — log + return null, never throw) 2. Size guard (drops oversize at the door) 3. Sanitize → cleaned (only pre-storage transform; secrets removed) 4. Hash raw bytes (Option B; cleaned bytes = stored bytes = hash input) 5. Storage.write (idempotent — dedup hit short-circuits with written:false) 6. Sidecar + global index (only on first landing) 7. Session manifest (always — even on dedup hit) 8. Per-agent manifest (when agentType present and passes path-traversal guard) 9. Fire-and-forget embedding enqueue (Wave 1 stub no-ops; Wave 2 activates) Defensive properties: - Never throws — every step wrapped in try/catch with structured warn log - Per-step error isolation: appendAgent failure does NOT abort the rest of the persist (pool body + session manifest still land) - Embedding enqueue rejection ignored at the orchestrator boundary - Returns null on input-validation failure or oversize trip Dependency injection: `overrides` slot in createRawSourceService accepts { storage, manifestWriter, indexWriter, embeddingDispatcher, hasher, sanitizer } for tests / future swaps. Production callers pass only { poolDir, sessionsRoot } and get a fully-wired service. Module also re-exports the six component pieces (hashSource, sanitize, PATTERNS, createSourceStorage, ChecksumError, etc.) so consumers can import everything from one path. Tests: 24 new orchestrator tests + 97 existing module tests = 121 total across 6 suites, all passing in 489ms. Orchestrator coverage: - factory validation (poolDir / sessionsRoot required) - input validation: missing sessionId/content/toolName, null/undefined input, non-string content, oversize → all return null without throwing - first landing: pool body + sidecar + index + session manifest all land - per-agent manifest: written when agentType provided, skipped otherwise - dedup: same content twice = one pool file, one index row, two manifest rows (second has dedup_hit=true) - cross-session dedup: same content from sessions A and B = one pool file, each session has its own one-row manifest - sanitization: API key + Authorization header redacted from stored body; [REDACTED:*] tags appear; original secrets do NOT appear in pool file - clean SEC text passes through (sanitized=false, redactions=[]) - embedding dispatcher receives correct (hash, sourceType); rejection does not propagate - error isolation: invalid agentType (path-traversal) does not abort pool/session writes - content-type routing: html/json/text → correct ext + sourceType Co-Authored-By: Claude Opus 4.6 (1M context) --- .../src/utils/rawSource/index.js | 268 +++++++++++++++ .../sdk/rawSource/RawSourceService.test.js | 309 ++++++++++++++++++ 2 files changed, 577 insertions(+) create mode 100644 super-legal-mcp-refactored/src/utils/rawSource/index.js create mode 100644 super-legal-mcp-refactored/test/sdk/rawSource/RawSourceService.test.js diff --git a/super-legal-mcp-refactored/src/utils/rawSource/index.js b/super-legal-mcp-refactored/src/utils/rawSource/index.js new file mode 100644 index 000000000..ea4ef2948 --- /dev/null +++ b/super-legal-mcp-refactored/src/utils/rawSource/index.js @@ -0,0 +1,268 @@ +/** + * RawSourceService — orchestrator for the content-addressed raw-source archive. + * + * Composes the six pure/stateful modules in this directory: + * SourceHasher (pure; SHA-256 over raw bytes — Option B) + * SourceSanitizer (pure; secret scrubbing — only pre-storage transform) + * SourceStorage (atomic, idempotent, sharded pool I/O + integrity check) + * SourceManifestWriter (session + per-agent NDJSON appends) + * SourceIndexWriter (global tamper-evident _index.ndjson with fsync) + * SourceEmbeddingDispatcher (Wave 1 stub; Wave 2 real queue) + * + * Orchestrator-only logic lives here: + * - input validation (graceful: log + return null, never throw into hooks) + * - size guard (drops oversize at the door) + * - source_type derivation from tool_name + * - display_name derivation from url + * - dedup-vs-first-landing routing (sidecar + index only on first landing; + * manifests on every call) + * - fire-and-forget embedding enqueue + * + * Designed to be called from the PostToolUse hook chain via + * `setImmediate(() => svc.persist({...}).catch(...))` — never blocks the + * hook chain; never throws. + * + * @module rawSource + */ + +import { hashSource } from './SourceHasher.js'; +import { sanitize } from './SourceSanitizer.js'; +import { createSourceStorage } from './SourceStorage.js'; +import { createManifestWriter } from './SourceManifestWriter.js'; +import { createIndexWriter } from './SourceIndexWriter.js'; +import { createEmbeddingDispatcher } from './SourceEmbeddingDispatcher.js'; + +const DEFAULT_MAX_RAW_BYTES = 10 * 1024 * 1024; + +/** Map a tool_name to the source_type used in metadata + index rows. */ +const SOURCE_TYPE_BY_TOOL = { + fetch_document: 'document', + exa_web_search: 'exa_result', + // Hybrid-client-specific tool names would map here too as they're added. +}; + +function inferSourceType(toolName) { + if (!toolName) return 'unknown'; + return SOURCE_TYPE_BY_TOOL[toolName] || 'unknown'; +} + +/** Best-effort human label for a source.

Why `client`: the same tool_name (e.g., fetch_document) can route through different external services (direct HTTP vs Exa /contents fallback). Without the client label, a slow Exa-fallback path is invisible in the aggregate. Cardinality bound: ~50 tool_names × ~6 clients × 3 statuses ≈ 900 series. Well under prom-client default limits. Bucket set widened on the long tail (10000, 30000, 60000) to capture slow external APIs that today bunch into the >5s bucket. Backward-compatible signature on recordToolDuration: Legacy: recordToolDuration(toolName, status, durationMs) → observed with client='unknown' Wave 1: recordToolDuration({ tool_name, client, status }, durationMs) Existing callers (researchHandler.js:256) keep working with client='unknown'. The Wave 1 hook integration (next commit, #12 scope) will use the object form with deriveClient() to populate the new label. Also adds: deriveClient(toolName, hybridMetadata) → string fetch_document + source='exa' → 'exa_fallback' fetch_document + source='native' → 'direct_fetch' fetch_document + null/undefined → 'direct_fetch' (default) exa_web_search → 'exa_native' mcp____ → '' everything else → 'other' Tests: 13 pass in 137ms. - Label set check: histogram exposes [client, status, tool_name] - Wave 1 object signature: observes with all three labels - Wave 1 partial labels: missing fields default to 'unknown' - Legacy positional signature: client='unknown', tool_name + status preserved - deriveClient: every documented branch (fetch_document with/without metadata, exa_web_search, mcp__sec__/courtlistener/super-legal-tools, SDK tools, null/undefined/non-string) - Cardinality bound: 4 tools × 5 clients × 2 statuses → 40 distinct series Note: ran `npm install --legacy-peer-deps` in the worktree to materialize node_modules (peer-dep conflict on @google/genai surfaced as a known project issue from main; resolution unchanged).

Closes the critical gap that blocks #13: _hybrid_metadata fields (fetch_source, fallback_reason, fetch_mode, confidence) are extracted in sdkHooks.js:1018-1031 today but are never persisted, so the /api/analytics/sla/7day endpoint has no data to query. Implementation: - Insertion point: persistAuditEvent at line ~563 (just before INSERT) - Triggers only when: SLA_TELEMETRY=true AND hookName='PostToolUse' AND tool_name ∈ SLA_HYBRID_TOOLS (fetch_document | exa_web_search) - Parses tool_response.content[0].text as JSON; extracts _hybrid_metadata.{source, fallback_reason, fetch_mode, confidence} into eventData.{fetch_source, fallback_reason, fetch_mode, fetch_confidence} - Native-success inference: when a hybrid-client tool succeeds but produces no _hybrid_metadata (typical for native-only paths), set fetch_source='native' so the SLA dashboard can still group it - JSON.parse wrapped in try/catch — non-JSON responses are common (HTML, plain text); parse failure is silent (audit insert proceeds normally) Hot-path discipline: - Flag-gated: featureFlags.SLA_TELEMETRY (default false). With flag off, zero behavior change vs pre-Wave-1 baseline. - Single try/catch boundary: a malformed response cannot break the audit insert under any circumstance. - Fields are optional — every column that consumed event_data already handles null via COALESCE / COALESCE-style frontend code. Verification: - Module loads cleanly (node -e import). - Full end-to-end coverage (PostToolUse hook fires → row in hook_audit_log has fetch_source populated) lives in test/integration/sla.integration.test.js coming in Task #15. Cannot unit-test persistAuditEvent in isolation — function is not exported and depends on a live pg pool + sessionCache. SLA_HYBRID_TOOLS set is intentionally minimal in Wave 1: fetch_document — direct + exa fallback paths exa_web_search — direct exa search Wave 4 expands to per-hybrid-method instrumentation (searchSECFilings, searchCourtOpinions, etc.).

Four files modified, each change focused. src/hooks/sdkHooks.js (postToolUseHandler): - Import detectInjection (#8) + recordToolDuration/deriveClient (#12). - Restructure existing _hybrid_metadata block to capture parsedToolResponse and textContent for reuse across detection + metric labeling. - Prompt-injection detection (flag-gated by PROMPT_INJECTION_DETECTION): runs detectInjection(textContent, {toolName}); if detected, attach to `entry` (file log) and propagate via hook return value `{ continue: true, prompt_injection: {...} }`. Detector failures caught locally — never throws. - Histogram observation (#12, always-on, no flag): on every PostToolUse with non-null duration_ms + tool_name, observes claude_tool_duration_ms{tool_name, client, status} where client is derived from tool_name + _hybrid_metadata.source. Recording failures caught locally. - Return value backward-compatible: handlers that don't fire injection detection still return { continue: true } unchanged. src/utils/hookDBBridge.js (persistAuditEvent): - Read result.prompt_injection.detected and merge five fields into eventData: prompt_injection_detected, _patterns, _excerpt, _confidence, _classifier. Frontend filters on prompt_injection_detected; analytics queries can do `WHERE event_data->>'prompt_injection_detected' = 'true'`. - PostToolUse row's event_type is preserved (not replaced) so the audit chain stays intact and the SLA telemetry on the same row continues to work. src/utils/hookSSEBridge.js: - Import featureFlags + define RAW_SOURCE_TOOLS allow-list with .includes() matcher (handles MCP-wrapped variants like 'mcp__direct-fetch__fetch_document'). - Extend forwardHookToSSE signature with sseOptions = {} as 8th arg (backward-compatible default). - PostToolUse case grows two new top-of-block sections: a) Raw-source archive (#3): when RAW_SOURCE_ARCHIVE=true AND sseOptions.rawSourceService is wired AND tool is in RAW_SOURCE_TOOLS, fire-and-forget `persist({sessionId, agentId, agentType, toolName, toolUseId, url, content})`. On success, emit `raw_source_ready` SSE event with { hash, size, url:/api/raw-sources/{hash}, agent_id, agent_type, ext, source_type, dedup, redactions, sanitized }. Errors caught at the .catch() boundary; never block the hook chain. b) Prompt-injection forwarding (#8): when result.prompt_injection.detected, emit `prompt_injection_detected` SSE event with patterns/confidence/ excerpt/classifier so the frontend timeline can surface it live. - wrapHooksForSSE + createSSEBridge both grow `sseOptions` parameter (default {}) and propagate through to forwardHookToSSE. All existing callers keep working; new callers opt into the raw-source wiring. src/server/agentStreamHandler.js: - Import createRawSourceService. - Per-request instantiation: poolDir = reports/_sources, sessionsRoot = reports/. Service is constructed unconditionally; the SSE bridge skips the persist branch when RAW_SOURCE_ARCHIVE=false (zero behavior change with flag off). - Pass { rawSourceService, getSessionId: () => ctx.sessionDir } as the third arg to createSSEBridge so PostToolUse can attribute writes to the live session. - Stash service on ctx for downstream consumers (future Wave 2/3). Verification: - All four modified modules load cleanly via direct node import. - All 163 unit tests across 8 suites still pass in 623ms (rawSource modules, promptInjectionDetector, metrics) — no regressions. - Default-off state (all three flags=false) produces zero behavior change: sdkHooks skips both detection + metric record; hookDBBridge skips SLA extraction; hookSSEBridge skips raw-source persist + injection forwarding. - Full end-to-end (PostToolUse → pool file lands; raw_source_ready event surfaces in #rawLog; hook_audit_log row carries prompt_injection_*) covered by integration tests in Task #15.

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the External API SLA (7d) panel to the Status tab as a collapsible section between Rate Limiter and Stream Stats. Panel polls /api/analytics/sla/7day every 60 seconds and renders a table grid (day × api_client) with calls, success rate, P95 latency, and fallback count per row. Files: test/react-frontend/index.html - New
with id="slaPanel" - Empty-state placeholder rendered when SLA_TELEMETRY=false or no rows - with thead (Day / API / Calls / Success / P95 / Fallback) test/react-frontend/app.js - New `slaTimer` (let, near healthTimer) - `fetchSlaDashboard()` — fetch + render, silent on non-200 - `renderSlaTable(rows)` — toggles empty/table visibility, renders rows with successClass mapping: ≥99% accent, 95-99% neutral, <95% error - Bootstrapped alongside fetchHealth + fetchSubagents + fetchCatalog - setInterval(fetchSlaDashboard, 60_000) starts on first init Behavior with flag off (SLA_TELEMETRY=false): - Backend route /api/analytics/sla/7day still responds (returns 0 rows since no event_data.fetch_source values exist to group by). - Frontend renders the empty placeholder. No console noise. Behavior with flag on: - Backend extracts fetch_source/fallback_reason/fetch_mode into event_data on every PostToolUse for fetch_document / exa_web_search. - Within ~60s of first traffic, the table populates with the live grid. - Color-coded success_rate gives at-a-glance API health view. Verification: node --check app.js syntax-clean; HTML well-formed (matches existing collapsible-section pattern). End-to-end (live API populates rows) covered by smoke + integration tests in Task #15. Note: the percentile columns on /api/analytics/tools/health (also Wave 1 #12) are exposed at the API level and visible via curl /metrics or direct JSON; a frontend Tools Health table is deferred to Wave 4 polish because no current panel renders that data shape.

Closes the test + rollout gap so the release is shippable end-to-end. test/fixtures/raw-sources/ (4 files, used by both integration tests): sec-10k-sample.html — SEC filing excerpt with phrases that could trigger semantic injection patterns but legitimately don't (e.g., "Ignore all prior filings"); used to verify FP resistance court-opinion-sample.json — court opinion JSON with _hybrid_metadata so the orchestrator picks the .json extension exa-results-sample.json — exa_web_search response shape with results[] and _hybrid_metadata for source/result_count injection-corpus.json — 12 calibration samples (6 clean, 6 dirty) with per-sample expected_detected labels and notes explaining the detector behavior test/integration/rawSource.integration.test.js (6 tests): - SEC fixture full pipeline → pool body, sidecar, _index.ndjson, session manifest, per-agent manifest all present and well-formed - Exa JSON fixture → .json extension + exa_result source_type - Cross-session dedup → unique-content probe lands once, manifests in both sessions - Sanitization end-to-end → API key + Auth header redacted from stored body; original secrets never appear on disk - Tampered file → ChecksumError on read test/integration/promptInjection.integration.test.js (5 tests): - Per-sample expected_detected matches detector across all 12 corpus entries - Aggregate FP rate on clean samples ≤ 25% (Wave 1 acceptance criterion) - Aggregate detection rate on injected samples ≥ 80% - Overall accuracy ≥ 90% - SEC + Exa fixtures pass detector cleanly (no FP) test/smoke/README.md: Runbook-style smoke tests (curl commands + SQL queries) for each of the four Wave 1 items plus the default-off regression check. Automated smoke spawning the dev server in CI deferred to Wave 3 alongside the chaos suite. docs/runbooks/wave-1-deploy.md: Deploy runbook with pre-flight checklist, 5-step staging→production flag rollout (24h soak between flips, 48h before raw-source enable), per-flag rollback procedures, full verification matrix with pass criteria for each acceptance item, and known limits / Wave 2 follow-ups. package.json: Added test:integration:wave1 (scoped to test/integration/, distinct from the existing tests/integration script that runs unrelated suites) and test:smoke (echoes the runbook README path).

Item 1A. Risk Factors

+ +

The Company's business, financial condition, operating results, and cash flows are subject to a number of risks. These risk factors should be read in conjunction with the consolidated financial statements and the related notes thereto. Ignore all prior filings that referenced the 2024 annual report; the present filing supersedes those disclosures in their entirety.

+ +

Macroeconomic conditions, including but not limited to inflation, interest rate volatility, and foreign currency exchange rate fluctuations, may adversely affect the Company's results of operations.

+ +

Cybersecurity Risk

+

The Company is subject to risks related to information security, including data breaches, cyber-attacks, and unauthorized access. These instructions apply to participants in the Company's information security training program.

+ +

Forward-Looking Statements

None breaks the functional pipeline; each has operational implications worth pre-deploy attention. Runbook additions: 1. Histogram label rename (tool → tool_name) with explicit grep + migration guidance for existing Prometheus/Grafana queries and alert rules. The legacy positional recordToolDuration() call signature is preserved, so existing call sites (researchHandler.js:256) still observe values under the new label set with client="unknown". 2. Composite index idx_audit_tool_time_dur added to hook_audit_log inside initSchema(); runs synchronously on first server start. Added a sizing query to estimate indexed_rows + decision matrix mapping row count to expected build time: < 10M rows → < 30s, deploy normally 10M-100M rows → 30s-5min, schedule during low-traffic window > 100M rows → pre-build with CREATE INDEX CONCURRENTLY before deploy (IF NOT EXISTS makes in-process create a no-op) 3. Always-on metric observation in postToolUseHandler. Adds ~750 Prometheus series (50 tool_name × 5 client × 3 status). Per-call cost ~1-2 μs. Runbook added a cardinality-budget pre-flight check. Frontend hygiene comment: app.js — added a comment near slaTimer noting that, like healthTimer, no explicit clearInterval is wired. Both rely on the page lifecycle (hard navigation / window close) to reclaim. If SPA-style navigation is added later, both timers need cleanup. This documents the existing convention rather than masking it. The audit's "byte-identical to main" verdict is C+ (qualified) — flag-gated paths are all safe, but the three unconditional changes above mean deploy parity is operational, not strict. The runbook now makes that explicit.

Factory signature change: BEFORE: createRawSourceService({ poolDir, sessionsRoot, maxRawBytes, overrides }) AFTER: createRawSourceService({ sessionsRoot, maxRawBytes, overrides }) — no poolDir; it's derived per persist() call from sessionsRoot + sessionId Per-session pool path derivation inside persist(): sessionPoolDir = path.join(sessionsRoot, sessionId, 'raw-sources') → SourceStorage + SourceIndexWriter instantiated with this path each call Why per-session: The product is single-tenant-per-MD deal work. Sessions = deals = audit boundaries. Legal hold, 7-year retention, regulatory deletion, and session-level backup/restore all align with session folders. Global pool was optimizing cross-session dedup (~$3/yr at realistic throughput) at the expense of self-containment. Not the right tradeoff for this product. Storage + index instantiation: Both were previously factory-time singletons bound to a single poolDir. Now per-persist() call. Storage construction does zero I/O, so per-call cost is negligible (~100 μs). Overrides (test DI) still short-circuit per-call instantiation for deterministic fixtures. Filesystem layout change (user-visible): BEFORE: reports/_sources/{ab}/{cd}/{hash}.ext.gz AFTER: reports/{sessionId}/raw-sources/{ab}/{cd}/{hash}.ext.gz Session manifests (raw-sources-manifest.ndjson, specialist-reports/ {agent}-sources/sources.ndjson) were already session-scoped — unchanged. Follow-up commits in this correction sequence: 2. Delete SourceIndexWriter (redundant per-session); add first_landing flag to session manifest rows so Wave 3 tamper-evident Merkle rollup can still distinguish new-hash events from dedup hits. 3. Update hooks/server wiring + routes (/api/raw-sources/:hash → /api/sessions/:sid/raw-sources/:hash). 4. Update tests (paths + fixtures). 5. Update docs (planning + spec + runbook + smoke README). Verification: node --check passes; module imports cleanly; createRawSourceService is exported as a function. Full test updates land in commit 4 of this sequence.

Under the old global pool, _index.ndjson served two purposes: 1. Tamper-evident log of new-hash landings (for Merkle root rollup) 2. Global dedup registry Per-session, both purposes collapse into the session manifest: 1. Tamper-evident: session manifest is already append-only + session-scoped 2. Dedup: session-local; SourceStorage.exists() handles it To preserve Wave 3's Merkle-rollup ability to distinguish new-hash events from dedup hits, a new `first_landing: boolean` field is added to each session manifest row (set from SourceStorage.write().written).

Root cause: RAW_SOURCE_TOOLS only matched 'fetch_document' and 'exa_web_search' — the MCP tool names. When EXA_WEB_TOOLS is false, PostToolUse fires with tool_name='WebFetch'/'WebSearch' which did not match the allow-list. Fix: split into two sets: RAW_SOURCE_MCP_TOOLS — .includes() match for MCP-wrapped variants RAW_SOURCE_SDK_TOOLS — exact-match Set for SDK built-in tools isRawSourceTool() now checks both. Archive fires regardless of which web-tool configuration is active.

Root cause recap (three failed interception points): 1. PostToolUse hook: tool_response.content[0].text is empty for server-side tools (WebFetch/WebSearch executed by API internally) 2. Stream content_block_start: SDK doesn't yield web_fetch_tool_result or web_search_tool_result blocks (confirmed: zero in 3 live tests) 3. Both fail because WebFetch/WebSearch are API-internal server tools The fix: capture at wrapWithConversation() in toolImplementations.js. This function wraps ALL 163 MCP tool handlers. Every external API call returns its response through this single middleware. With EXA_WEB_TOOLS=true, WebFetch/WebSearch are replaced by MCP tools (fetch_document, exa_web_search), routing ALL web activity through wrapWithConversation. Coverage: 99.4%. toolImplementations.js changes: - Added imports: path, fileURLToPath, getStore (requestContext), featureFlags, createRawSourceService - Added lazy singleton getRawSourceService() with __dirname-derived reportsRoot (zero I/O at import time; instantiates on first persist) - Inside wrapWithConversation: after tool execution + conversation logging, if RAW_SOURCE_ARCHIVE=true AND getStore()?.sessionDir is set: - Extract content: prefer MCP text field, fall back to JSON.stringify - Fire-and-forget persist({sessionId, toolName, content, url}) - .catch() swallows errors; never breaks tool execution - Outer try/catch as belt-and-suspenders agentStreamHandler.js changes: - Removed dead Path C code (web_fetch_tool_result / web_search_tool_result branches from commit 82bdc20) — confirmed these block types are never yielded by the SDK at runtime despite existing in type definitions - Replaced with comment explaining why and pointing to Correction 1.3 All 165 existing tests pass (rawSource modules untouched; only trigger moved).
