Fixed: non-fatal NATS connect + `WorkflowOrchestrator::new(config, swarm, kg, nats, db)` in `main.rs`; 503 only when NATS is genuinely unavailable. +- **`WorkflowService` was missing from `AppState`**: `api/workflows.rs` existed with all handlers referencing `state.workflow_service`, but the field did not exist — module was commented out with `// TODO: Phase 4`. Fixed: + - `workflow_service: Option>` added to `AppState` + - `with_workflow_service(Arc)` builder added + - Non-fatal init chain in `main.rs`: `AgentRegistry → AgentCoordinator → StepExecutor → WorkflowEngine + WorkflowBroadcaster + AuditTrail → WorkflowService` + - `pub mod workflows` uncommented in `api/mod.rs` + - `.nest("/api/v1/workflows", api::workflows::workflow_routes())` added to router; 503 on coordinator init failure +- **`get_workflow_audit` Result bug**: `workflow_service.get_audit_trail(&id).await` returned `anyhow::Result>` but the result was used directly as `Vec` — compile-time oversight. Fixed with `.map_err(|e| ApiError(...))?`. + +#### `vapora-llm-router` — `try_fallback_with_budget` was a no-op + +- `try_fallback_with_budget` iterated the fallback provider list but never called any provider — the loop body only collected names. Fixed: accepts `prompt: String` + `context: Option`; calls `provider.complete(prompt.clone(), context.clone()).await`; logs cost on success, logs error on per-provider failure, returns `AllProvidersFailed` only when all are exhausted. +- `complete_with_budget` now clones `prompt`/`context` before the primary call so ownership is available for the fallback path. +- Pre-existing `cost as u32` no-op casts removed (both occurrences). + +#### `vapora-tracking` — hollow VAPORA integration layer + +- `TrackingPlugin::on_task_completed`: was `Ok(())`. Now constructs a real `TrackingEntry` (`source: WorkflowYaml`, `impact: Backend`) and calls `self.db.insert_entry(&entry).await?`. +- `TrackingPlugin::on_document_created`: was `Ok(())`. Now constructs a real `TrackingEntry` (`source: CoderChanges`, `impact: Docs`, `files_affected: 1`, `details_link: Some(path)`) and persists it. +- `events` module (`#[cfg(feature = "async-nats")]`): `NatsPublisher` struct implemented — wraps `Arc`, `publish_entry_created(&TrackingEntry)` serializes to JSON and publishes to `{prefix}.{source:?}` subject. + +#### `vapora-doc-lifecycle` — workspace integration + all three plugin stubs + +- Crate added to workspace members (was completely isolated — `cargo check -p vapora-doc-lifecycle` returned "no match"). +- `Cargo.toml`: broken `doc-lifecycle-core` path fixed (`../doc-lifecycle-core` → correct relative path to `Tools/doc-lifecycle-manager/crates/doc-lifecycle-core`). +- `error.rs`: added `From`. +- `classify_session_docs(task_id)`: scans `.coder/` directory via async stack-walk (`collect_md_docs`), calls `Classifier::classify(path, Some(content))` on each `.md` file, logs type + confidence. +- `consolidate_docs()`: scans `config.docs_root`, calls `Consolidator::find_duplicates(&docs)`, warns on each `SimilarityMatch` with path pair and score. +- `update_rag_index()`: scans `config.docs_root`, chunks each doc via `RagIndexer::chunk_document`, calls `generate_embeddings`, zips embeddings back into `chunk.metadata.embedding`, calls `build_index`. +- `documenter.rs`: added `nats: Option>` field + `with_nats()` builder. +- `update_root_files(task_id)`: appends timestamped line to `{docs_root}/CHANGES.md` using `OpenOptions::append`. +- `publish_docs_updated_event(task_id)`: JSON payload `{event, task_id, timestamp}` published to `config.nats_subject` when NATS is configured; debug-logged and skipped when not. + +#### `audit/mod.rs` — Merkle tamper-evident audit trail (previous session) + +- **Replaced append-only log** with a hash-chained Merkle audit trail. +- `block_hash = SHA256(prev_hash|seq|entry_id|timestamp_rfc3339|workflow_id|event_type|actor|details_json)` — modifying any field invalidates the hash and every subsequent entry. +- `prev_hash` on the genesis entry is `GENESIS_HASH` (64 zeros). +- `write_lock: Arc>` serializes writes so `(seq, prev_hash)` fetched from DB is always consistent. +- `verify_integrity(workflow_id) -> IntegrityReport` — recomputes every block hash from stored fields; returns `IntegrityReport { valid: bool, total_entries, first_tampered_seq: Option }`. +- `AuditEntry` gains `prev_hash: String` and `block_hash: String` fields; SurrealDB schema updated. +- **ADR-0039**: design rationale, limitations (truncation, single-process lock, no HMAC key), and deferred alternatives (NATS append-only stream, HMAC authentication). + +--- + ### Added - Security Layer: SSRF Protection and Prompt Injection Scanning #### `vapora-backend/src/security/` — new module diff --git a/Cargo.lock b/Cargo.lock index f130785..6a18b57 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2807,6 +2807,22 @@ dependencies = [ "urlencoding", ] +[[package]] +name = "doc-lifecycle-core" +version = "0.1.0" +dependencies = [ + "anyhow", + "globset", + "once_cell", + "regex", + "serde", + "serde_json", + "thiserror 2.0.18", + "tokio", + "tracing", + "walkdir", +] + [[package]] name = "document-features" version = "0.2.12" @@ -12394,6 +12410,7 @@ dependencies = [ "clap", "dotenv", "futures", + "hex", "http", "jsonwebtoken 10.3.0", "lazy_static", @@ -12407,6 +12424,7 @@ dependencies = [ "serde", "serde_json", "serde_yaml", + "sha2", "sqlx", "surrealdb 3.0.0", "tempfile", @@ -12478,6 +12496,25 @@ dependencies = [ "vapora-shared", ] +[[package]] +name = "vapora-doc-lifecycle" +version = "1.2.0" +dependencies = [ + "anyhow", + "async-nats", + "async-trait", + "chrono", + "doc-lifecycle-core", + "serde", + "serde_json", + "tempfile", + "thiserror 2.0.18", + "tokio", + "tracing", + "tracing-subscriber", + "uuid", +] + [[package]] name = "vapora-frontend" version = "1.2.0" diff --git a/Cargo.toml b/Cargo.toml index 1cfeb97..9849a5c 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -15,6 +15,7 @@ members = [ "crates/vapora-a2a", "crates/vapora-a2a-client", "crates/vapora-tracking", + "crates/vapora-doc-lifecycle", "crates/vapora-worktree", "crates/vapora-knowledge-graph", "crates/vapora-analytics", diff --git a/crates/vapora-backend/Cargo.toml b/crates/vapora-backend/Cargo.toml index 1be2c75..7540685 100644 --- a/crates/vapora-backend/Cargo.toml +++ b/crates/vapora-backend/Cargo.toml @@ -74,6 +74,8 @@ tower-cookies = { workspace = true } # Utilities uuid = { workspace = true } chrono = { workspace = true } +sha2 = { workspace = true } +hex = { workspace = true } dotenv = { workspace = true } once_cell = { workspace = true } regex = { workspace = true } diff --git a/crates/vapora-backend/src/api/mod.rs b/crates/vapora-backend/src/api/mod.rs index 5119405..873f618 100644 --- a/crates/vapora-backend/src/api/mod.rs +++ b/crates/vapora-backend/src/api/mod.rs @@ -20,8 +20,7 @@ pub mod tasks;

Enterprise compliance frameworks (SOC 2, ISO 27001, HIPAA) require tamper-evident logs where post-hoc modification is provably detectable. + +--- + +## Decision + +Replace the append-only audit log in `vapora-backend/src/audit/mod.rs` with a Merkle hash-chain where each entry cryptographically commits to every entry before it. + +--- + +## Context + +### Why Append-Only Is Insufficient + +An append-only log prevents deletion (assuming no `DELETE` privilege) but does not prevent modification. An attacker with write access to `audit_entries` can silently rewrite the `event_type`, `actor`, or `details` fields of any existing row without leaving any trace detectable by the application. + +The previous implementation stored `seq`, `entry_id`, `timestamp`, `workflow_id`, `event_type`, `actor`, and `details` — but no integrity metadata. Any row could be updated without detection. + +### Merkle Hash Chain Model + +Each audit entry stores two additional fields: + +- `prev_hash` — the `block_hash` of the immediately preceding entry (genesis entry uses `GENESIS_HASH = "00...00"` / 64 zeros) +- `block_hash` — SHA-256 of the concatenation: `prev_hash|seq|entry_id|timestamp_rfc3339|workflow_id|event_type|actor|details_json` + +Modifying *any* covered field of entry N invalidates `block_hash` of entry N, which causes `prev_hash` in entry N+1 to mismatch its predecessor's hash, propagating invalidation through the entire suffix of the chain. + +### Write Serialization + +Fetching the previous hash and appending the new entry must be atomic with respect to other concurrent appends. A `write_lock: Arc>` serializes all `append` calls within the process. This is sufficient because VAPORA's backend is a single process; multi-node deployments would require a distributed lock (e.g., a SurrealDB `UPDATE ...

A separate monotonic counter or external timestamp anchor would address this. +2. **Single-process write lock**: The `Arc>` is sufficient for a single backend process. Multi-node deployments need a distributed lock or a database-level sequence generator with compare-and-swap semantics. +3. **SHA-256 without salting**: The hash is deterministic given the inputs. This is correct for tamper detection (you want reproducibility) but means the hash does not serve as a MAC (an attacker who rewrites a row can also recompute a valid hash chain if they have write access). For full WORM guarantees, chain anchoring to an external append-only service (e.g., a transparency log) would be required. +4. **Key rotation not addressed**: There is no HMAC key — `sha2` is used purely for commitment, not authentication. Adding a server-side HMAC key would prevent an attacker with DB write access from forging a valid chain, but requires key management. + +--- + +## Alternatives Considered + +### Database-Level Audit Triggers + +SurrealDB (v3) does not expose write triggers that could hash entries at the storage level. A pure DB-level solution is not available. + +### External Append-Only Log (NATS JetStream with `MaxMsgs` and no delete) + +Would require a separate NATS stream per workflow and cross-referencing two storage systems. Deferred — the Merkle chain provides sufficient tamper evidence for current compliance requirements without external dependencies. + +### HMAC-based Authentication + +Adds server-side secret management (rotation, distribution across nodes).
