From ff8afe32aa026e17055729e440664252d9b76b6d Mon Sep 17 00:00:00 2001 From: code-engineer Date: Fri, 10 Apr 2026 17:46:55 +0200 Subject: [PATCH 01/12] =?UTF-8?q?chore:=20prep=20for=20import-file=20wirin?= =?UTF-8?q?g=20=E2=80=94=20interface=20split=20+=20markdown=20extractor?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 3b prep commit. Adds the name-agnostic extraction pipeline restructuring that the import-file route handler will orchestrate in the next commit(s): - packages/core/src/extraction-pipeline.ts: split interface. Converter returns { mdIntermediate: string } only via ConverterOutput. ExtractionOutput { mdIntermediate, triples, provenance } remains as the composite type assembled by the orchestrator (route handler). - packages/core/src/index.ts: export ConverterOutput. - packages/cli/src/extraction/markitdown-converter.ts: return type updated to ConverterOutput (no behavior change, same binary invocation). - packages/cli/src/extraction/markdown-extractor.ts: NEW Phase 2 structural extractor (~331 lines) implementing deterministic node-side extraction from Markdown. Handles YAML frontmatter, wikilinks, tags, Dataview inline fields, heading structure. No LLM, no external deps. - packages/cli/src/extraction/index.ts: exports the new extractor. - packages/cli/test/extraction-markdown.test.ts: NEW 27 unit tests covering structural extraction cases. All pass. - packages/core/test/extraction-pipeline.test.ts: updated for split interface. 7/7 pass. - packages/cli/test/document-processor-e2e.test.ts: updated for split interface. - packages/cli/test/extraction-markitdown.test.ts: updated for split interface. Next commit wires POST /api/assertion/:name/import-file to orchestrate Phase 1 (converter) + Phase 2 (markdown extractor) and write triples to the target assertion. Prep commit ships no new HTTP routes — the existing import-file endpoint in daemon.ts is unchanged until Phase 3b completes wiring.

Adds two building blocks the import-file route handler will consume in the next commit: - packages/cli/src/file-store.ts: content-addressed disk store for uploaded files and markdown intermediates. sha256-keyed with a two-level sharded directory layout (ab/cdef...). put/get/has APIs return `sha256:` prefixed hashes which the route handler surfaces as fileHash and mdIntermediateHash in ImportFileResponse. Idempotent: re-putting the same bytes yields the same hash and overwrites with identical content. - packages/cli/src/http/multipart.ts: minimal RFC-7578 multipart/ form-data parser. Handles the exact subset the import-file endpoint needs: one file part with filename + content-type headers, plus any number of text parts. No nested multipart, no base64 transfer-encoding, no streaming (parses a buffered Buffer). Zero new npm dependencies. Throws MultipartParseError on malformed input so the caller can return a clean 400. Tests: - packages/cli/test/file-store.test.ts: 12 unit tests covering put/ get/has/hashToPath, idempotency, binary content, empty input, malformed-hash handling, bare-hex vs sha256:-prefixed forms. - packages/cli/test/multipart.test.ts: 19 unit tests covering parseBoundary (standard, quoted, case-insensitive, missing), and parseMultipart (text fields, file fields, mixed bodies, binary content with 0x00/0xff bytes, malformed input error paths). All 31/31 tests pass. CLI build clean. No route handler changes yet — the next commit wires POST /api/assertion/:name/import-file to use these primitives.

charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the import-file document ingestion endpoint and its companion extraction-status polling endpoint on the daemon. Wires Phase 1 (converter) → Phase 2 (markdown structural extractor) → write triples to the assertion graph, matching the orchestration described in 05_PROTOCOL_EXTENSIONS.md §6.5. New endpoints: - POST /api/assertion/:name/import-file (multipart/form-data) Fields: file (required) — the uploaded document bytes contextGraphId (required) — target context graph contentType (optional) — override the file part's Content-Type ontologyRef (optional) — CG _ontology URI for Phase 2 guided extraction subGraphName (optional) — target sub-graph inside the CG Orchestration: 1. Parse multipart body, store original file in FileStore → fileHash 2. Resolve detectedContentType (explicit field > multipart Content-Type) 3. Phase 1: - text/markdown → skip converter, use raw bytes as mdIntermediate - registered converter → run converter.extract(), store MD result in FileStore → mdIntermediateHash - no registered converter → graceful degrade: return status="skipped", no triples written, file blob retained for later manual extraction 4. Phase 2 → extractFromMarkdown({ markdown, agentDid, ontologyRef, documentIri: assertionUri }) → triples + provenance 5. Ensure assertion graph exists (idempotent), write triples + provenance via agent.assertion.write 6. Record in in-memory ExtractionStatusRecord map, return ImportFileResponse Error paths return typed extraction.status = "failed" with the error message. Sub-graph registration errors propagate from assertionCreate/Write (finding 4 of issue #81). - GET /api/assertion/:name/extraction-status?contextGraphId=...&subGraphName=... Returns the current extraction job state for an assertion by looking up the in-memory record. Synchronous extractions populate this on the import-file response; this endpoint lets agents re-query without holding the original response and provides the hook for async extraction workflows in V10.x. Supporting changes: - packages/cli/src/daemon.ts: - Import contextGraphAssertionUri, extractFromMarkdown, FileStore, parseBoundary, parseMultipart, MultipartParseError - New constant MAX_UPLOAD_BYTES = 50 MB for document uploads - New interface ExtractionStatusRecord - New readBodyBuffer() helper — Buffer variant of readBody for binary multipart payloads - Instantiate FileStore at {dataDir}/files and extraction-status Map at daemon start; thread both into handleRequest via two new parameters - Log message for missing MarkItDown updated to clarify markdown uploads still work - packages/cli/test/skill-endpoint.test.ts: - Regex tolerance for CRLF line endings in the YAML frontmatter check (/^---\r?\n/ instead of /^---\n/). Pre-existing test was Windows-hostile because Git's core.autocrlf normalizes LF → CRLF on checkout. Linux CI was fine; Windows was failing. Tolerant regex fixes both. Tests: - All existing cli tests pass unchanged: multipart 19/19, file-store 12/12, extraction-markdown 27/27, extraction-markitdown 8/8, document-processor-e2e 13/13 (4 expected skips), skill-endpoint 11/11, extraction-pipeline 7/7. - Integration tests for the new route handlers land in the next commit. CLI build clean (TypeScript).

SKILL.md updates: - §5 Memory Model "Working Memory (WM)" section: removed the "🚧 Planned" marker on the assertion API (create/write/query/promote/ discard ship as of PR #108; import-file and extraction-status ship in this PR). Listed the full shipped API surface with body shapes, added the import-file and extraction-status endpoints, and noted the sub-graph registration check from issue #81 finding 4 so agents know to createSubGraph() before targeting one. - §7 File Ingestion: replaced the "🚧 Planned" section with complete documentation of the shipped POST /api/assertion/{name}/import-file endpoint: - Two-phase pipeline overview (Phase 1 converter, Phase 2 structural extractor) with explicit text/markdown skip-Phase-1 note - Request table listing all form fields (file, contextGraphId, contentType, ontologyRef, subGraphName) - End-to-end curl example - Response shape with all fields populated - Extraction status semantics (completed / skipped / failed) - GET /api/assertion/{name}/extraction-status usage for polling Integration tests (packages/cli/test/import-file-integration.test.ts): NEW 12-test suite that exercises the full Phase 1 → Phase 2 → assertion.write orchestration without requiring a full DKGAgent (which needs libp2p + chain). Uses real FileStore (temp dir), real ExtractionPipelineRegistry, real extractFromMarkdown, real parseMultipart, and a mock agent that captures assertion.create/write calls for verification. This drives the exact call sequence the daemon route handler does, so it covers the orchestration end-to-end. Happy paths (5 tests): - text/markdown upload skips Phase 1, runs Phase 2, writes triples covering every extractor feature (rdf:type, schema:name from frontmatter title, schema:mentions from wikilink, schema:keywords from hashtag, Dataview status field, dkg:hasSection headings) - text/markdown detection from filePart Content-Type header when no explicit contentType field is provided - contentType text field overrides the file part Content-Type - Registered PDF converter runs Phase 1, stores MD intermediate via FileStore with a separate mdIntermediateHash distinct from fileHash, runs Phase 2 on the converter's output - ontologyRef threaded through to the converter - subGraphName threaded through to assertion.create and assertion.write Graceful degrade (2 tests): - Unregistered content type (image/png): file stored with correct magic bytes preserved, status="skipped", pipelineUsed=null, no triples written, no assertion.create/write called - File part with no Content-Type header defaults to application/octet- stream and also degrades gracefully Extraction-status semantics (2 tests): - startedAt and completedAt timestamps populated on success - Multiple imports to different assertions get separate status records keyed by assertionUri Boundary parsing (2 tests, via parseBoundary wrapper): - Extracts boundary from daemon-style header - Rejects non-multipart requests skill-endpoint.test.ts updates: - Replaced the stale "marks planned endpoints clearly" test (which asserted /api/assertion/create was planned — no longer true) with two tests: one that confirms the *(planned)* marker still exists (for context graph sub-resources and agent profile), and a new test "documents the now-shipped assertion API surface" that verifies all 7 shipped assertion routes (create/write/query/promote/discard/ import-file/extraction-status) appear in SKILL.md.

Widen the signature to string | string[] | undefined and reject array values as ambiguous so the route handler returns a clean 400 instead of 500-ing inside the parser. 2. The outer write-stage catch in the import-file handler only matched has-not-been-registered / Invalid / Unsafe errors and rethrew everything else without updating the extraction status record. That left /extraction-status stuck reporting in_progress on unexpected agent.write() failures even after the import had failed. Record the failure via recordFailedExtraction(...) before rethrowing so the status reflects reality. Mirror the same fix in the import-file orchestration test helper, which had the same shape.

Anchor both `name=` and `filename=` matches to a real `;` parameter boundary (or start of string). 2. import-file route: an empty `contentType=` form field was treated as a real override because `??` only catches null/undefined, not empty string. A client sending `contentType=` would downgrade a valid text/markdown / application/pdf upload to application/octet-stream and trigger graceful-degrade. Treat blank/whitespace overrides as absent in both the daemon route handler and the test orchestration helper. 3. /.well-known/skill.md discovery: text/markdown is hard-coded as a supported native ingestion type by the import-file route (skip Phase 1, run Phase 2 markdown extractor directly), but extractionRegistry.availableContentTypes() only listed registered Phase 1 converters. Skill clients reading the discovery surface would think Markdown ingestion was unavailable when it was actually always supported. Surface text/markdown alongside the registered converters in both the skill.md endpoint and the startup log. Adds 5 tests: - parseMultipart rejects parts with only filename= and no name= - parseMultipart parses filename-first ordering correctly - parseMultipart parses name= and filename= independently - import-file orchestration treats blank contentType= as absent - import-file orchestration treats whitespace-only contentType= as absent Co-Authored-By: Claude Opus 4.6 (1M context) --- packages/cli/src/daemon.ts | 28 ++++++++++-- packages/cli/src/http/multipart.ts | 8 +++- .../cli/test/import-file-integration.test.ts | 44 ++++++++++++++++++- packages/cli/test/multipart.test.ts | 41 +++++++++++++++++ 4 files changed, 114 insertions(+), 7 deletions(-) diff --git a/packages/cli/src/daemon.ts b/packages/cli/src/daemon.ts index eebe954ea..010c10f26 100644 --- a/packages/cli/src/daemon.ts +++ b/packages/cli/src/daemon.ts @@ -818,8 +818,15 @@ async function runDaemonInner(foreground: boolean, config: Awaited 0 + ? contentTypeOverrideRaw + : undefined; const ontologyRef = textField('ontologyRef'); const subGraphName = textField('subGraphName'); diff --git a/packages/cli/src/http/multipart.ts b/packages/cli/src/http/multipart.ts index 523d44495..104415419 100644 --- a/packages/cli/src/http/multipart.ts +++ b/packages/cli/src/http/multipart.ts @@ -120,11 +120,15 @@ export function parseMultipart(body: Buffer, boundary: string): MultipartField[] if (!disposition) { throw new MultipartParseError('Malformed part: missing Content-Disposition'); } - const nameMatch = disposition.match(/name\s*=\s*(?:"([^"]*)"|([^;]+))/i); + // Anchor parameter matches to a real `;` boundary (or start of string) so + // `name=` doesn't accidentally match the `name=` substring inside `filename=`, + // and vice versa.
