The protocol defines four entry statuses plus one pre-submission state (draft, which lives in the agent's buffer, not in the store). + +**Interpretation chosen**: I implement the protocol exactly. The storage layer has four statuses: +- `active` — entry is live and constrains the workspace +- `superseded` — entry has been replaced by a newer entry +- `archived` — entry is old and excluded from default queries +- `tombstoned` — message redacted, graph structure preserved + +The prompt's "validated", "approved", "conflicted", "merged", and "deleted" do not exist as entry statuses in the protocol: +- Validation is a check that happens at submit time, not a status +- Approval does not exist — the protocol is trustless at the validation layer +- Conflict is a property of a (scope, cid) pair, not a status of an individual entry +- Merge is an operation, not a status — merged entries become active in the target scope +- Delete does not exist — entries are tombstoned instead + +--- + +## Ambiguity 2: Immutability vs. Status Mutation + +**Protocol says (Appendix B — Storage Format)**: "Records are never modified after creation." + +**Protocol also says (Section 3 — Supersede)**: "The protocol marks the target as `status: 'superseded'`." + +These are contradictory. Marking a target as superseded requires an UPDATE, which violates "never modified after creation." + +**Interpretation chosen**: Content (id, cid, message) is immutable — never changes after creation. The id proves content integrity. Status is mutable lifecycle metadata — it changes as entries transition through the lifecycle (active → superseded/archived/tombstoned). This preserves the content-addressed integrity guarantee while allowing the lifecycle the protocol requires. + +Implementation: the `status` column is updated in place. All other columns are immutable after insert. A trigger or application check prevents status from transitioning backward (e.g., superseded → active). + +--- + +## Ambiguity 3: Cycle Detection Feasibility + +**Prompt requires**: "Detect and reject cycles at write time." + +**Protocol analysis**: Cycles in the supersession chain are structurally impossible in an append-only DAG where: +1. Entries are immutable — you cannot change an existing entry's `supersedes` field +2. New entries supersede older entries (forward reference) +3. The new entry does not exist yet when the supersedes reference is checked + +Given A exists, and B is created with `supersedes = A.id`: tracing from A through the supersession chain can never reach B because B doesn't exist yet. The only way to create a cycle (A → B → C → A) would require modifying A after B and C exist, which immutability prevents. + +**Interpretation chosen**: I implement cycle detection for defense-in-depth. The check traces the supersession chain from the target entry through all ancestors. If any ancestor's id matches the new entry's computed id (which shouldn't happen since it's not yet inserted), the write is rejected. This is a safety net for bugs, not a case the protocol can produce in normal operation. + +--- + +## Ambiguity 4: Event Log Separate Table? + +**Prompt requires**: "Append-only event log for state transitions." + +**Protocol analysis**: The entries table IS the event log. Each entry records a state transition: +- A new entry with `status: "active"` is a "created" event +- An entry with `supersedes` set is a "superseded" event for the referenced target +- An entry with `status: "archived"` is an "archived" event + +The protocol does not define a separate event log table. + +**Interpretation chosen**: The `entries` table is the sole event log. State transitions are recorded by: +- Creating a new entry (active → becomes part of active set) +- Updating an existing entry's status to superseded/archived/tombstoned (forward lifecycle transition) + +No separate event table. The appended log of entries PLUS the status update history IS the complete event record. + +--- + +## Summary of Exact Protocol Compliance + +| Dimension | Implemented As | Source |

Five passes: scope resolution (inheritance across ancestor scopes), status filter, CID dedup with supersession resolution, inherentance (child overrides parent), and kind-ordered output. Key features: - Scope inheritance: child scopes inherit parent entries unless overridden - Conflict detection: duplicate cids within same scope with different messages and no supersession are flagged, both entries returned - Supersession resolution: superseded entries never leak into output - Token budget: compress observations first, then decisions; never drop rules silently; all drops logged with reason - Task relevance ranking: optional keyword-based relevance scoring - Caching: per (scope, budget, kind, cid), invalidated on scope change - Provenance: every compiled entry tracks sourceScope, inherited flag, fromParent, and supersedesChain - Graceful degradation: summarize before dropping, never silently drop high-confidence constraints 69 tests pass (26 store, 26 compiler, 17 DAG) --- docs/CONFLICT_RESOLUTION.md | 180 +++++++++ packages/protocol/src/compiler-types.ts | 50 +++ packages/protocol/src/compiler.ts | 479 +++++++++++++++++++++++ packages/protocol/src/index.ts | 11 +- packages/protocol/src/store.ts | 13 + packages/protocol/tests/compiler.test.ts | 401 +++++++++++++++++++ 6 files changed, 1133 insertions(+), 1 deletion(-) create mode 100644 docs/CONFLICT_RESOLUTION.md create mode 100644 packages/protocol/src/compiler-types.ts create mode 100644 packages/protocol/src/compiler.ts create mode 100644 packages/protocol/tests/compiler.test.ts diff --git a/docs/CONFLICT_RESOLUTION.md b/docs/CONFLICT_RESOLUTION.md new file mode 100644 index 0000000..f2910f9 --- /dev/null +++ b/docs/CONFLICT_RESOLUTION.md @@ -0,0 +1,180 @@ +# Conflict Resolution in the Context Compiler + +**How the Compiler resolves conflicting commitments — with worked examples.** + +## The Two Sources of Conflict + +Conflicts arise from two distinct mechanisms: + +### 1.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the Supabase-backed v1 with a local-first MCP server built on @contextly/protocol (Store + Compiler). Five tools matching protocol primitives: - read_context: compiled context via Context Compiler with budget, kind, cid, and task-relevance options - commit: idempotent entry creation with conflict detection - query: raw SQLite lookup bypassing compilation (for tooling/debug) - resolve: conflict resolution via supersession - fork/merge: scope branching with inheritance Auth handshake: - Token format: ctx_{scope}_{base64url} — embeds scope for zero-DB auth - verifyTokenIntegrity, validateScope, permission checks on every call - Parent token grants access to child scopes, sibling scopes are isolated Rate limiting: - Per-operation sliding window (read: 100/min, write: 30/min, etc.) - Resets after window expiry, structured RateLimitError with retryAfter Structured errors: - Machine-readable error codes (INVALID_TOKEN, SCOPE_MISMATCH, etc.) - Agents can reason about errors programmatically, not just HTTP codes Integration test (16 tests): - Two-agent loop: Alice reads empty context, commits → Bob reads Alice's context, commits his own → both see all entries - Conflict detection: Alice and Bob write different messages for same cid - Conflict resolution: Bob supersedes Alice's entry with a new decision - Auth enforcement: scope mismatch rejects, parent-child scope allows - Rate limiting: window enforcement and auto-reset - Fork with inheritance: child scope inherits parent entries - Idempotency: duplicate commit returns existing entry --- package-lock.json | 18 +- packages/mcp-server/package.json | 18 +- packages/mcp-server/src/auth.ts | 96 +++ packages/mcp-server/src/errors.ts | 85 ++ packages/mcp-server/src/index.test.ts | 91 -- packages/mcp-server/src/index.ts | 796 ++++++++++-------- packages/mcp-server/src/rate-limiter.ts | 75 ++ packages/mcp-server/tests/integration.test.ts | 344 ++++++++ packages/mcp-server/tsconfig.json | 12 +- packages/mcp-server/vitest.config.ts | 11 + packages/protocol/src/compiler.ts | 10 +- 11 files changed, 1073 insertions(+), 483 deletions(-) create mode 100644 packages/mcp-server/src/auth.ts create mode 100644 packages/mcp-server/src/errors.ts delete mode 100644 packages/mcp-server/src/index.test.ts create mode 100644 packages/mcp-server/src/rate-limiter.ts create mode 100644 packages/mcp-server/tests/integration.test.ts create mode 100644 packages/mcp-server/vitest.config.ts diff --git a/package-lock.json b/package-lock.json index d11c928..5391dbb 100644 --- a/package-lock.json +++ b/package-lock.json @@ -10603,28 +10603,16 @@ }, "packages/mcp-server": { "name": "@contextly/mcp-server", - "version": "1.0.0", - "license": "ISC", + "version": "2.0.0", "dependencies": { - "@contextly/shared": "*", - "@modelcontextprotocol/sdk": "^1.0.1", - "@supabase/supabase-js": "^2.45.4", - "zod": "^3.23.8" + "@contextly/protocol": "*", + "@modelcontextprotocol/sdk": "^1.0.1" }, "devDependencies": { "typescript": "^5.9.3", "vitest": "^1.6.1" } }, - "packages/mcp-server/node_modules/zod": { - "version": "3.25.76", - "resolved": "https://registry.npmjs.org/zod/-/zod-3.25.76.tgz", - "integrity": "sha512-gzUt/qt81nXsFGKIFcC3YnfEAx5NkunCfnDlvuBSSFS02bcXu4Lmea0AFIUwbLWxWPx3d9p8S5QoaujKcNQxcQ==", - "license": "MIT", - "funding": { - "url": "https://github.com/sponsors/colinhacks" - } - }, "packages/protocol": { "name": "@contextly/protocol", "version": "0.2.0", diff --git a/packages/mcp-server/package.json b/packages/mcp-server/package.json index bc65871..f586371 100644 --- a/packages/mcp-server/package.json +++ b/packages/mcp-server/package.json @@ -1,24 +1,20 @@ { "name": "@contextly/mcp-server", - "version": "1.0.0", + "version": "2.0.0", + "type": "module", "main": "dist/index.js", + "types": "dist/index.d.ts", "scripts": { "build": "tsc", "start": "node dist/index.js", - "dev": "tsc -w", "test": "vitest run" }, "dependencies": { - "@contextly/shared": "*", - "@modelcontextprotocol/sdk": "^1.0.1", - "@supabase/supabase-js": "^2.45.4", - "zod": "^3.23.8" + "@contextly/protocol": "*", + "@modelcontextprotocol/sdk": "^1.0.1" }, "devDependencies": { "typescript": "^5.9.3", "vitest": "^1.6.1" - }, - "keywords": [], - "author": "", - "license": "ISC" -} + } +} \ No newline at end of file diff --git a/packages/mcp-server/src/auth.ts b/packages/mcp-server/src/auth.ts new file mode 100644 index 0000000..8ca9d82 --- /dev/null +++ b/packages/mcp-server/src/auth.ts @@ -0,0 +1,96 @@ +import { createHash, randomBytes } from "node:crypto"; + +/** + * Token format: ctx_{scope}_{base62random} + * + * Example: ctx_project.myapp_K4xq7T2mN9pV1cF8jL3wR5bY6aH0gDe + * + * The token embeds the scope so the server can authorize requests + * without a database lookup.

No Data Loss + +Every entry that is successfully inserted into a local Store is preserved. The append-only log is immutable — entries are never modified or deleted (status transitions are additive). Even if an entry is superseded, archived, or tombstoned, the original message is still present in the local log and the relay log. + +### 2. Idempotent Push + +Pushing the same entry to the relay multiple times produces exactly one copy on the relay. The relay deduplicates by content hash (`SHA256(scope + "." + cid + "." + message)`). This is guaranteed at the relay layer — the second push returns `status: "duplicate"`. + +### 3. Deterministic Entry Identity + +Every entry has a globally unique, content-addressed id. Two agents writing the same `(scope, cid, message)` produce the same id. This means: +- No UUID coordination needed between agents +- No central ID authority +- Idempotent merge — merging the same branch twice is safe + +### 4. Strong Consistency Within a Single SQLite Store + +On a single machine, all reads and writes to the Store go through SQLite with WAL mode and transactions. A write is immediately visible to all subsequent reads on the same Store instance. No stale reads within a single process. + +### 5. Causal Ordering Within a Supersession Chain + +If entry B supersedes entry A, then B is guaranteed to appear after A in the history for that cid. The Store enforces this at insert time: B cannot be inserted unless A already exists and is active. The relay enforces the same invariant. + +### 6. Conflict Detection on Pull + +When pulling entries from the relay, the SyncEngine runs the same conflict detection as the Store's insert path. If two entries exist for the same `(scope, cid)` with different messages and no supersession relationship, a `Conflict` is produced. Both entries remain active. The conflict is surfaced in the `SyncSummary.conflicts` array. + +### 7. Compiler Cache Invalidation After Sync + +After a pull completes, the SyncEngine calls `compiler.invalidateScope()`. Subsequent `compile()` calls will recompute the active set from the updated store. Stale compiled output is never served after a sync. + +--- + +## Best-Effort (Not Guaranteed, but Handled Gracefully) + +### 1. Clock Synchronization + +The protocol assigns timestamps at the relay level (`timestamp` field), not at the client level. Local timestamps are set on offline writes but are overwritten by the relay's timestamp on push. + +**What can go wrong**: During offline operation, local timestamps may drift. After sync, the relay's timestamp is canonical. If two agents write offline and both push later, the relay assigns new timestamps on acceptance. The local timestamp is preserved but the relay's timestamp is used for ordering. + +**Impact**: If clock skew > a few seconds, the ordering of entries from different agents may not reflect real-world ordering. The protocol does not depend on clock ordering for correctness — supersession is explicit (via `supersedes`), not implicit (via timestamp). + +### 2. Simultaneous Offline Writes to the Same (scope, cid) + +Two agents can independently write to the same `(scope, cid)` while both are offline. When both come online and push: + +1. Both entries are accepted by the relay (different content hashes → different ids) +2. Both agents pull and see the other's entry +3. The compiler detects the conflict and returns both entries as active + +**No data is lost.** Both versions are preserved. The conflict must be resolved manually (or by a future agent writing a superseding entry). + +### 3. Network Partitions + +Under network partition: +- Each partition can continue to write and read locally (full offline capability) +- When the partition heals, push and pull operations transfer all missed entries +- Conflicts are detected during pull (see "Simultaneous Offline Writes" above) + +**No split-brain scenario** exists because entries are append-only and content-addressed. There is no "last writer wins" scenario — both versions are always preserved. The only question is which version, if any, is treated as "active" for a given cid, and that is determined by explicit supersession, not by timing. + +### 4. Partial Push Failure + +If a push operation is interrupted mid-way (network failure, process crash): +- Some entries may have been accepted by the relay, others not +- On retry, already-accepted entries return `status: "duplicate"` (idempotent) +- Failed entries are retried +- No partial state is left on the relay + +**Impact**: The local `pending_entries` table may show some entries as `synced` and others as `pending`. On retry, only pending entries are sent. The relay handles duplicates gracefully. + +--- + +## Not Guaranteed + +### 1. Global Total Ordering + +There is no global clock. Entries from different scopes have no defined ordering relationship. Even within a scope, entries from different agents may have timestamps that don't reflect real-world ordering if clock skew exists. The only reliable ordering is: +- Within a supersession chain: B supersedes A → B after A +- Within a single Store: insertion order (SQLite rowid) + +### 2. Cross-Region Strong Consistency + +If the relay is replicated across regions (future feature), different regions may see entries at different times. The relay stores the canonical log in a single S3 prefix (or equivalent), so eventual consistency applies: + +- A push to region A may not be visible to a pull from region B for some time (seconds to minutes) +- This is inherent in S3's read-after-write consistency model for the same prefix +- If cross-region strong consistency is required, the relay must use a strongly consistent store (e.g., DynamoDB global tables with DAX) + +### 3. Real-Time Propagation + +There is no push-based notification system in the current protocol. Agents poll for new entries via `pull()` or `sync()`. The interval between polls determines how quickly context propagates. + +For real-time propagation, agents would need to either: +- Poll at a high frequency (trade-off: cost + latency) +- Use a WebSocket or Server-Sent Events connection to the relay (future feature) +- Use a local file watcher on the SQLite database (limited to same machine) + +### 4. Merge Atomicity with Conflicts + +The MergeEngine adopts non-conflicting entries even when conflicts exist in the same merge operation. This means: + +- If source has 3 entries and 1 conflicts with target, the 2 non-conflicting entries are adopted +- The 1 conflicting entry is returned in `conflicts[]`, not adopted +- The merge "completes" with partial adoption + +A true atomic merge (all-or-nothing) would require a two-phase protocol. The current design optimizes for adoption of non-conflicting entries rather than blocking on conflicts. + +--- + +## Summary Table + +| Property | Guaranteed? | Mechanism | +|----------|-------------|-----------| +| No data loss | ✅ | Append-only log, content-addressed | +| Idempotent push | ✅ | SHA256 content hash deduplication | +| Deterministic IDs | ✅ | `SHA256(scope + "." + cid + "." + message)` | +| Single-node strong consistency | ✅ | SQLite WAL + transactions | +| Conflict detection | ✅ | Compiler + SyncEngine detect at pull time | +| Cache invalidation after sync | ✅ | `compiler.invalidateScope()` | +| Clock-independent correctness | ✅ | Supersession is explicit, not timestamp-based | +| Global total ordering | ❌ | No global clock | +| Cross-region strong consistency | ❌ | S3 eventual consistency | +| Real-time propagation | ❌ | Poll-based; no push mechanism | +| Atomic merge with conflicts | ❌ | Partial adoption; conflicts returned separately | +| Offline write safety | ✅ | Content-addressed, no loss, conflicts detected \ No newline at end of file diff --git a/packages/protocol/src/index.ts b/packages/protocol/src/index.ts index b26aec8..810025e 100644 --- a/packages/protocol/src/index.ts +++ b/packages/protocol/src/index.ts @@ -17,4 +17,33 @@ export { type CompilerOptions, type DropRecord, type Provenance, -} from "./compiler-types"; \ No newline at end of file +} from "./compiler-types"; +export { + InMemoryRelay, + MergeEngine, + SyncEngine, + type CloudRelay, + type MergeResult, + type PendingEntry, + type PendingResult, + type PullOptions, + type PullResult, + type PushResult, + type RelayScopeState, + type SyncError, + type SyncState, + type SyncSummary, +} from "./sync/index.js"; +export { + ConflictResolver, + authorityLevel, + type AggregatedConflict, + type AutoResolveResult, + type EscalationPolicy, + type FeedbackRecord, + type ManualResolveInput, + type ResolutionRecord, + type ResolutionRule, + type ResolutionRuleName, + type ResolverStats, +} from "./resolver/index.js"; \ No newline at end of file diff --git a/packages/protocol/src/resolver/index.ts b/packages/protocol/src/resolver/index.ts new file mode 100644 index 0000000..9728f34 --- /dev/null +++ b/packages/protocol/src/resolver/index.ts @@ -0,0 +1,13 @@ +export { ConflictResolver, authorityLevel } from "./resolver"; +export type { + AggregatedConflict, + AutoResolveResult, + ConfidenceFn, + EscalationPolicy, + FeedbackRecord, + ManualResolveInput, + ResolutionRecord, + ResolutionRule, + ResolutionRuleName, + ResolverStats, +} from "./types"; \ No newline at end of file diff --git a/packages/protocol/src/resolver/resolver.ts b/packages/protocol/src/resolver/resolver.ts new file mode 100644 index 0000000..de2c0d2 --- /dev/null +++ b/packages/protocol/src/resolver/resolver.ts @@ -0,0 +1,383 @@ +import Database from "better-sqlite3"; +import { createHash } from "node:crypto"; +import { Store, type Conflict, type ContextEntry } from "../index"; +import { Compiler } from "../compiler"; +import type { + AggregatedConflict, + AutoResolveResult, + EscalationPolicy, + FeedbackRecord, + ManualResolveInput, + ResolutionRule, + ResolutionRuleName, + ResolverStats, +} from "./types"; + +function isoNow(): string { + return new Date().toISOString(); +} + +function computeConflictId(scope: string, cid: string, ids: string[]): string { + const sorted = [...ids].sort(); + const hash = createHash("sha256") + .update(`conflict:${scope}:${cid}:${sorted.join(":")}`) + .digest("hex"); + return `conflict:${hash}`; +} + +export function authorityLevel(author: string): number { + if (author.startsWith("human:")) return 3; + if (author.startsWith("agent:")) { + const name = author.slice(6); + if (name && name !== "anonymous") return 2; + return 1; + } + if (author === "anonymous") return 0; + return 0; +} + +function scopeDepth(scope: string): number { + return scope.split(".").length; +} + +export type ConfidenceFn = (entry: ContextEntry) => number; + +export class ConflictResolver { + private store: Store; + private compiler: Compiler; + private db: Database.Database; + private confidenceFn: ConfidenceFn; + + constructor( + store: Store, + compiler: Compiler, + opts?: { db?: Database.Database; confidenceFn?: ConfidenceFn }, + ) { + this.store = store; + this.compiler = compiler; + this.db = opts?.db ?? store.getDb(); + this.confidenceFn = opts?.confidenceFn ??

server with all protocol primitives - Add API server package with Express.js - Implement all 6 protocol primitives as REST endpoints: - POST /v1/read_context - read compiled context - POST /v1/commit - create context entries - POST /v1/query - query/filter entries - POST /v1/resolve - resolve conflicts - POST /v1/fork - fork scopes - POST /v1/merge - merge scopes - Add authentication middleware (API keys + JWT Bearer tokens) - Implement scope-based authorization with permissions - Add rate limiting (per-tenant and per-API-key) - Build webhook system with retries, idempotency, signed payloads - Auto-generate OpenAPI spec from implementation - Swagger UI at /docs - Postman collection included - Comprehensive test suite --- api/server/src/index.ts | 64 ++ packages/api/server/README.md | 307
