(Optional) Switch the agent loop to `claude-agent-sdk` - -DataMind ships two interchangeable agent-loop implementations: - -| Backend | How it talks to the model | When to pick it | -|---|---|---| -| `native` (default) | Pure Python, `anthropic` SDK → your gateway | Simplest deploy, fewest deps | -| `sdk` | `claude-agent-sdk` → `claude` CLI → **CCR** (local translator) → your gateway | Want the SDK's own Subagents / Compaction facilities | - -The role-scoped tool registries (19 read/utility tools for RetrieveAgent and 11 write tools for StoreAgent), the event shape, the frontend, **and DataMind's own safety HookChain** (PathAllowlist / DestructiveSql / AuditLog) all work identically either way — only the inner loop changes. On `native` the HookChain runs at the loop's dispatch chokepoint; on `sdk` it runs inside each MCP tool wrapper. Same chain instance, same Allow/Deny/AskUser/Rewrite decisions, same audit log. - -> Note: the SDK's *own* hook system (its `PreToolUse`/`PostToolUse` API) is a separate thing from DataMind's `HookChain`. DataMind's safety hooks are enforced on both backends regardless of which one you pick. - -### Why CCR - -The SDK always speaks Anthropic's `/v1/messages` protocol. If your upstream gateway only speaks OpenAI `/v1/chat/completions`, put `claude-code-router` (CCR) in the middle — it's a tiny Node process that translates both directions. - -### Start CCR - -```bash -# Install node >= 18. Then point CCR at your upstream: -export UPSTREAM_BASE=http://your-gateway.example.com/v1 # OpenAI-compatible -export UPSTREAM_KEY=sk-... -export UPSTREAM_MODEL=claude-sonnet-4-6 - -bash scripts/start_ccr.sh -# → listens on http://127.0.0.1:13456 -``` - -Keep it running in its own terminal. - -### Switch DataMind to the SDK backend - -```bash -# In .env.datamind or inline: -export DATAMIND__AGENT__BACKEND=sdk -export DATAMIND__AGENT__CCR_BASE_URL=http://127.0.0.1:13456 - -# Everything else is unchanged: -python -m datamind chat -python -m uvicorn datamind.server:app --port 8000 -``` - -Server startup logs will show the active backend: - -``` -INFO agent_loop_backend backend=sdk ccr=http://127.0.0.1:13456 -``` - -Switch back to native any time by setting `DATAMIND__AGENT__BACKEND=native` (or removing the var — `native` is the default). - ---- - -## 9. Add your own data — three ways - -There are three ways to put data into DataMind, and they coexist. Pick whichever fits your workflow. - -### 9.1 Agentic storage (recommended for ad-hoc additions) - -StoreAgent owns all writes across the five data surfaces.

- DataMind inference-time data plane -

- -

StoreAgent writes on the warm path. RetrieveAgent reads across the shared data plane and returns evidence.

- -> **v1.0.0** — stable native backend + local profile storage. SDK/CCR and remote database adapters are supported integration paths; validate them in your own environment. - -## The idea - -Most agent systems can retrieve knowledge, but they have nowhere to put the new fact they just learned. DataMind gives the runtime two explicit roles: - -~~~text -message / file / CSV / relationship - │ - ▼ - StoreAgent ─────── write receipt ───────▶ KB · DB · Graph · Skills · Memory - │ - │ next question - ▼ - RetrieveAgent ◀──── evidence + answer ──── shared data plane -~~~ - -This is **inference-time data**: not model training data, not a batch ETL pipeline, -and not an unbounded chat transcript. It is scoped, inspectable state that can -change while an agent is running. - -## Two agents. One hard boundary. - - - - - - -
- -### StoreAgent - -Chooses a destination and writes: - -- documents and chunks -- rows and tables -- graph triples -- profile skills -- durable memories - -Returns a receipt describing what changed. - - - -### RetrieveAgent - -Chooses sources and reads: - -- semantic KB search -- SQL inspection and queries -- graph traversal -- Skills and safe utilities -- scoped Memory recall - -Returns an answer with normalized evidence. - -
- -The split is enforced in code, before tools reach the model. RetrieveAgent sees -19 read/utility tools; StoreAgent sees 11 write tools. Every call also passes -through `PathAllowlistHook`, `DestructiveSqlHook`, and `AuditLogHook`. - -## Five surfaces, one answer - -- **KB / RAG** — documents, notes, policies, semantic search -- **Database** — exact numbers, filters, joins, aggregations -- **Knowledge Graph** — entities, relationships, multi-hop facts; ingest - structured triples or extract bounded triples from text files and directories -- **Skills** — reusable procedures and safe utilities -- **Memory** — preferences and durable facts, scoped to `global`, `profile`, or `session` - -Default providers are Chroma + BM25, SQLAlchemy (SQLite / MySQL / PostgreSQL), -NetworkX, profile-scoped `SKILL.md`, and SQLite memory. - -## Choose a way to use DataMind - -### 1. Codex plugin — local, single-user workflow - -The official Codex integration lives in [`plugins/datamind-context`](./plugins/datamind-context/). -It is a thin MCP adapter: it exposes DataMind's RetrieveAgent, StoreAgent, -RAG, GraphRAG and Memory capabilities to Codex and shares the same profile, -configuration and storage model. It does not ship a second DataMind runtime. - -~~~bash -./scripts/install_codex_plugin.sh -~~~ - -This is the shortest path to using DataMind with personal files and a local -Codex session. - -`datamind_use_folder` indexes supported text files into the KB and builds the -Graph by default. Use `datamind_graph_ingest` when you want graph-only ingest; -each generated edge keeps its source path for provenance and replacement on -re-ingest. - -### 2. DataMind service — concurrent, multi-session deployment - -Run the FastAPI server or place DataMind behind an authenticated service layer -when several sessions or users need to share a data plane. Requests carry their -own session and profile context; choose a shared database and storage backend -for a multi-process deployment. - -~~~bash -python -m uvicorn datamind.server:app --host 0.0.0.0 --port 8000 -~~~ - -The local SQLite profile is a convenient single-user baseline. Public or team -deployments need authentication, authorization, TLS, rate limits and an -appropriate shared backend; see the [DataMind documentation site](https://opendcai.github.io/DataMind-Doc/). - -### 3. Python, CLI and HTTP APIs - -Use `pip install datamind` when DataMind is embedded in another application or -when you want to call the runtime directly from Python, the CLI or HTTP. +**The shared workspace data layer for Codex.** Codex reasons, ingests and retrieves; +DataMind stores data, executes tools, and returns evidence and write receipts. + +[中文](./README_zh.md) · [Codex plugin](./plugins/datamind-context/) · +[CI](https://github.com/OpenDCAI/DataMind/actions/workflows/python-ci.yml) · +[Documentation](https://opendcai.github.io/DataMind-Doc/) + +```text +Local Codex (personal) Codex SDK (enterprise host) + └──────── main Codex agent ────────┘ + Skills + MCP + │ + shared DataMind data tools + KB · SQL · Graph · Skills · Memory + evidence · receipts · workspace revisions +``` + +The plugin, official Codex SDK integration, CLI, HTTP API and browser UI share +the same data layer.

Start `datamind_operation_begin(mode="write")` and fetch `workspace-ingest`. +2. `datamind_workspace_prepare(path)` returns a source inventory with SHA-256 versions. +3. Codex reads documents and submits `datamind_workspace_publish(path, surfaces, + graph_sources=[{uri, version, triples}, ...])`. Include an explicit empty list + for each new or changed document without relations (snapshot mode requires all documents). Set `truncated=true` when appropriate. +4. DataMind validates source versions, materializes the selected surfaces privately, + reuses completed source checkpoints, then publishes one complete revision. + Failed or conflicting publications preserve the previous head. +5. Start `datamind_operation_begin(mode="read")` to pin the published revision. + Reuse its `operation_id` across KB, SQL, graph and raw-evidence calls. Concurrent + publication does not move that reader. Start another operation to see newer data. + +Every tool after operation_begin requires the operation_id. Fetching a Skill +persists its version/hash for subsequent receipts in that operation. Skills and +Memory stay live profile context; they are outside the business-data snapshot. + +Incremental workspaces share immutable sources, source-scoped SQLite graph assertions, +LanceDB vector versions and Dolt table trees across revisions. New workspaces keep +only the latest version by default; choose recent N or all for historical rollback. +Active readers and protected revisions survive cleanup. Existing snapshot workspaces +keep their history and migrate explicitly. See [storage and migration](docs/WORKSPACE_STORAGE.md). + +Independent `kb_add_path`, `db_import_path`, `graph_replace_source` and explicit +triple writes remain available. They do not modify published snapshots. For graph +source replacement, Codex submits triples plus the expected source hash; validation +happens before retracting old support. `graph_forget_source` removes only that +source's managed support and preserves the original file and other evidence. + +## CLI, HTTP and UI + +```bash +pip install -e '.[codex]' +datamind info # no model startup +datamind ask "Who owns Project A?" # Codex with read-only data access +datamind store "Import this file" # same Codex host, authorized writes +datamind chat # /store permits writes, /new resets context +python -m uvicorn datamind.server:app --host 127.0.0.1 --port 8000 +``` + +The UI and `/api/ask`, `/api/store`, `/api/chat` call the same Codex host. Read +requests pin the published revision at admission, and tools enforce that binding +across calls. With no published workspace, a read request explicitly uses live +stores. The API's optional `revision` selects a retained historical snapshot. +Source uploads, direct KB administration, graph status and scoped Memory reads +remain available. Receipt IDs, request IDs and data-tool evidence are returned +from actual data calls, including when Codex uses code mode. + +## Migration to 2.0 + +The old `datamind.agent.build_datamind`, StoreAgent/RetrieveAgent classes, role +prompts, and Claude SDK/CCR agent adapter have been removed. Use `CodexHost` for +natural-language requests and `build_data_plane` for direct data operations. +`DATAMIND__CODEX__*` configures the main agent; the old native/sdk backend switch +no longer selects a product runtime. See [2.0 migration](./docs/LEGACY_RUNTIME.md). + +The plugin's direct-tool workflow, source checkpoints, immutable revisions, +source-scoped graph replacement and rollback remain the same. Prepared graph +assertions are supplied by Codex; direct Workspace builds do not implicitly +start a model. Optional explicit text utility clients remain supported for +custom pipelines and deterministic experiment fixtures. + +## Verify + +```bash +pip install -e '.[dev,codex]' +pytest -q datamind/tests plugins/datamind-context/tests python -m datamind.scripts.verify_sqlite_demo -~~~ - -The repository's CI runs the no-network test suite and the deterministic SQLite -demo.

Codex Plugin —— 本地单人工作流 - -官方 Codex 适配位于 [`plugins/datamind-context`](./plugins/datamind-context/)。 -它是一个薄 MCP 适配层，把 DataMind 的 RetrieveAgent、StoreAgent、RAG、 -GraphRAG 和 Memory 能力提供给 Codex，并和 DataMind 共用 profile、配置及 -存储。插件不包含第二套 DataMind runtime。 - -~~~bash -./scripts/install_codex_plugin.sh -~~~ - -这是使用个人文件和本地 Codex session 的最短路径。 - -`datamind_use_folder` 默认会把支持的文本文件写入 KB 并同步构建 Graph。 -如果只需要图谱入库，可以使用 `datamind_graph_ingest`；每条生成的边都会保留 -来源路径，重复入库时可按来源替换。 - -### 2. DataMind Service —— 并发、多 session 部署 - -当多个 session 或用户需要共享 data plane 时，运行 FastAPI 服务，或者把 -DataMind 放到带鉴权的服务层后面。每个请求携带自己的 session 和 profile -上下文；多进程部署应选择可共享的数据库和存储后端。 - -~~~bash -python -m uvicorn datamind.server:app --host 0.0.0.0 --port 8000 -~~~ - -本地 SQLite profile 适合作为单人基线。公网或团队部署还需要认证、授权、 -TLS、限流和合适的共享后端，详见 [DataMind 文档站](https://opendcai.github.io/DataMind-Doc/)。 - -### 3. Python、CLI 与 HTTP API - -需要把 DataMind 嵌入其他应用，或者直接从 Python、CLI、HTTP 调用时，使用 -`pip install datamind`。 - -## 快速开始 - -~~~bash -pip install datamind - -export DATAMIND__LLM__API_BASE=https://your-gateway.example.com -export DATAMIND__LLM__API_KEY=sk-... -export DATAMIND__LLM__PROTOCOL=anthropic # 或 openai_chat_completions -export DATAMIND__LLM__MODEL=claude-sonnet-4-6 - -datamind chat -~~~ - -或者启动浏览器界面： - -~~~bash -python -m uvicorn datamind.server:app --port 8000 -# http://127.0.0.1:8000 -~~~ - -协议必须显式设置，并会复用于外层 Agent loop 和内部生成（NL2SQL、multi-query、Memory、图谱抽取）。 - -

Missing/corrupt +artifacts are failures, not successful submissions. A `BLOCKED: ...` string is +not an export ID.

Diagnostics use the configured +log directory. Ordinary free-form prose without a contract remains compatible; +this does not prove semantic correctness of an answer. + +### Mistyped database identifiers + +Native SQLite tools reject unknown `database_id`/`database_ids` before accessing +data. Errors include the supplied invalid IDs, exact available IDs with their +source URIs in the current profile/operation, total count and truncation indicator. +The preview is limited to 20 databases; `db_list_databases` returns the full list. +Copy a complete ID without shortening it. Correct the arguments instead of +reimporting a file. There is no fuzzy automatic selection or cross-profile lookup. +The same error details are retained in MCP responses and diagnostic logs. + +### Existing Python calls + +Low-level `DBService.query_sql/export_sql` and existing Python tool calls without +intent remain compatible. Python callers can opt in by supplying intent, and can +require it by reusing a `RequestContext` whose `extra` contains +`query_contract_required=True`. Bind the same context or pass it to each +`DataPlane.call`; without a host/operation ID the context's stable `trace_id` +provides the scope.

Task/profile boundaries, +read-only SQL, bundle allowlists and final prediction integrity checks remain enabled. + +## Data flow + +| Input | General behavior | DataSpace test behavior | +| --- | --- | --- | +| CSV / TSV / XLSX | DB tables; retain Unicode column names and positional original-name mappings | Same | +| SQLite `.sqlite` / `.sqlite3` | Consistent native SQLite snapshot, registered in DB | Read-only registration of the original standalone file; no file or row copy | +| JSON table envelope | Existing document ingestion | Complete typed DB rows, schema cards in KB, and long text cells in KB | +| Other JSON / Markdown / PDF | Existing document ingestion | Same | +| MP4 | Existing video bundle, KB and Graph workflow | Same; automatic image viewing is unchanged | + +For structured JSON and SQLite, selecting Graph adds deterministic file-to-table, +table-to-column and declared foreign-key relationships. Model-supplied semantic +assertions remain optional for these structured sources. A matching field name +alone is not treated as a foreign key. Ordinary CSV graph routing is unchanged. + +DataSpace JSON is read in streaming passes. Values remain numbers, strings or +NULL, rather than being converted uniformly to text. Numeric-looking strings +such as `"000021"` stay strings. Duplicate rows remain duplicate. Nested JSON +cells and integers outside signed 64-bit range fail explicitly; they are not +silently flattened or rounded. An empty `records` array still gets a schema +card and an empty managed table with provenance columns, without inventing +business columns. JSON text cells of at least 160 characters are split into KB +chunks with source/table/column/row locators; short values remain in DB. KB is +not a copy of every numeric cell, and no model invents semantic relationships +as part of the deterministic adapter. Codex may supply additional explicitly +evidenced relationships through the existing `graph_sources` interface. + +## Column and source discovery + +`db_list_databases` discovers registered SQLite IDs, source versions, storage +mode and original table names. Pass `database_id` to `db_list_tables`, +`db_describe_table`, `db_query_sql`, `db_query_nl` or `db_export_sql` to use a +native source. Omitting it selects managed CSV/JSON tables, including +source-scoped `ws_...` names. `db_describe_table(table).source_metadata` exposes the original source +file, table name (`sheet`), column mapping, types, original declared types, +primary keys, foreign keys and row count when present. The workspace manifest +contains the same catalog. Direct CSV imports also persist their original +column mapping. Each mapping entry is positional: + +```json +{"ordinal": 1, "original_name": "收入（万元）", "name": "收入（万元）"} +``` + +Headers are trimmed and kept as quoted Unicode identifiers. Blank, duplicate, +control-character or reserved `_source_file` headers receive a stable fallback; +long names are limited to 64 characters and collisions are disambiguated. The +original header remains in `column_mapping`, including duplicate originals. +Use dialect-appropriate quotes, e.g. SQLite `SELECT "收入（万元）" FROM "ws_..."`. +CSV/XLSX values retain the existing TEXT/NULL import semantics. JSON has a +synthetic `_source_row` (or a nonconflicting variant) to locate long-text KB +hits. `_source_file` identifies the source for managed tables. Native SQLite keeps +its exact columns; provenance lives in the registry and Graph evidence. + +## Native SQLite registration + +With the standard policy, Workspace builds and direct `db_import_path` create +consistent SQLite snapshots with SQLite's backup API, including committed WAL data. Native schema +objects, views, indexes, constraints, collations and trigger definitions remain +in the file. Triggers are not replayed into a different database. Original +scalar types, BLOBs, NULLs and row multiplicity are preserved. No per-table CSV +cache or managed table copy is generated for SQLite. + +The DataSpace policy instead registers the original absolute file path in both +Workspace builds and direct imports. It +requires an independently readable database with no nonempty WAL or rollback +journal. The registry stores database ID, source URI/version, SHA-256, workspace +revision, storage ownership, full schema objects and column/foreign-key metadata. +DataSpace native queries and KB/Graph reads do not validate source versions or +checksums again. Keep inputs immutable for the whole run; +read-only connections alone do not prevent a different process changing files. +The test runner does not provide an operating-system sandbox. + +Ordinary native queries retain before/after validation of the selected snapshots. +A bounded process-local cache reuses successful hashes while device/inode, size, +nanosecond modification/change times and WAL/journal state match. Changed metadata +invalidates the check; unrelated KB/Graph tools do not scan databases. This cache +is not a substitute for OS-level immutability against a privileged writer. + +Native connections use read-only SQLite URIs, query-only mode, SQL guards and a +query deadline. Views are queried directly. Available built-in virtual modules +such as FTS5 work without flattening; a missing custom module is reported as a +schema/query error rather than silently skipping the table. Extensions are not +loaded automatically. `.db` remains unregistered because its format is ambiguous. + +For joins across registered SQLite files, supply `database_ids` to +`db_query_sql`/`db_export_sql`. Refer to an attached source as +`"database_id"."original_table"`. These IDs resolve only through the current +registry; the model cannot attach arbitrary paths. Omitting the primary +`database_id` joins these sources with the managed SQLite CSV/JSON database. +SQLite's limit of ten attached databases per query applies. Joining native +SQLite with a managed Dolt database in one statement is not implemented; query +those providers separately. Native SQLite itself does not get converted to Dolt. + +The manifest retains source-scoped table catalog keys for evidence identity; +for native tables use its `database_id` and `native_table` fields in SQL tools, +not the catalog key as a physical table name. KB schema cards and Graph locators +include the routing ID. Only schema and explicit declared relationships are +extracted automatically; views are not treated as inferred foreign keys. + +Use versioned Workspace publication for coordinated updates and retained +snapshots. Referenced DataSpace revisions do not retain historical source bytes: +changing a source during evaluation is outside the immutable-input contract and +is no longer detected by reference reads. Rebuild for a new input set. +GC never owns or deletes referenced inputs. Normal snapshot revisions remain +readable after the original file changes or disappears. Existing pre-native +revisions remain readable through Workspace; rebuild old DataSpace test +workspaces to use this new registration path. + +Direct `db_import_path` keeps native names (no `table_prefix`). For an already +registered source use `if_exists="replace"`; append does not concatenate SQLite +databases. `db_delete_path` unregisters a native source without deleting its +original file. Publication replaces the registry entry as a unit, so deleted tables +cannot linger from the old file. `db_update_path` remains the CSV/Excel interface. + +## Setup and execution + +From the repository root, in your activated Python environment: + +```bash +python -m pip install -e '.[dataspace]' +``` + +The `dataspace` extra adds `ijson`; regular SQLite/CSV ingestion needs no new +optional parser. Use a separate runtime root for tests. Each task receives a +separate `dataspace_task_N` profile, workspace and agent working directory. +Only `input/task_N/context` is registered as the input root. The agent working +directory is in the runtime profile, not the original dataset. The test entry +reads the question from that task's `task.json`; it never loads `output/`, +reference answers or evaluation configurations. The model prompt also forbids +other tasks and Memory. This is application-level task separation, not an OS +security boundary against an adversarial model with unrestricted filesystem tools. + +A DB-only build validates ingestion without model/API calls: + +```bash +python -m datamind.dataspace \ + --dataset-root /path/to/DataSpace-Benchmark \ + --runtime-root /path/to/dataspace-runtime \ + --task task_1 --phase build --surfaces db +``` + +The default on-demand run uses the existing Codex host. Configure embeddings +if KB indexing or search is needed, and the optional OCR/ASR providers for +video processing. Configure these as for ordinary DataMind; no credentials +are bundled by this change. + +```bash +python -m datamind.dataspace \ + --dataset-root /path/to/DataSpace-Benchmark \ + --runtime-root /path/to/dataspace-runtime \ + --task task_1 --phase run +``` + +`--phase build` publishes inputs and `--phase query` solves against the published +revision. The default `--phase run` uses on-demand tools without requiring a +full Workspace build. With an explicit `--sql`, `--phase run` instead performs +the build and deterministic query workflow. A model build must publish a new revision +with the requested surfaces and complete current inventory; an old workspace +cannot silently stand in for a failed build. `--sql 'SELECT ...'` substitutes an +explicit read-only query for model solving and is useful for offline checks. +Use `--database-id` with `--sql` to select a native source. It is not a +benchmark prediction generated by the agent. + +## Complete results + +The task setting `db.row_limit=None` reaches both the host and MCP subprocess. +It applies to direct and generated SQL. Explicit SQL `LIMIT`, query timeouts, +read-only guards and revision restrictions remain in effect. Normal runs still +use the configured 1,000-row default. Long-running benchmark queries may need a +larger `DATAMIND__DB__QUERY_TIMEOUT_S`; disabling a row cap does not disable timeouts. + +For final answers the test entry requires `db_export_sql`. It streams results +to `storage/dataspace_task_N/query_results/.csv` and returns only a +small preview plus the full row count, hash and pinned revision. The runner +checks `complete`, `truncated`, revision and hash before creating: + +```text +/predictions/task_N/prediction.csv +``` + +This avoids mistaking a shortened model/tool preview for the full answer. +The model still chooses the SQL and is responsible for the question's columns, +ordering and values. This adaptation does not establish benchmark accuracy. + +Direct filesystem ingestion does not use the web uploader, so its existing +25 MiB HTTP upload limit does not apply. The uploader itself is unchanged. +Existing published revisions stay readable; rebuilding creates a new revision +and applies the new column/schema rules without renaming old snapshots in place. + +## Offline verification + +```bash +python -m pytest -q datamind/tests plugins/datamind-context/tests +python scripts/verify_dataspace_inputs.py \ + --dataset-root /path/to/DataSpace-Benchmark \ + --runtime-root /path/to/dataspace-runtime \ + --task task_1 +``` + +The verifier requires an existing DB build. It compares managed CSV/JSON rows +and native SQLite query results with the originals, verifies SQLite reference +ownership, and checks a 1,505-row export. +The additional tests cover policy isolation, Unicode/duplicate headers, typed +SQLite and JSON values, BLOBs/NULLs/empty tables, retained revisions, schema +Graph evidence, explicit migration, full CSV export, mocked Codex orchestration, +and rejection of builds that did not publish. The mocked orchestration test +checks integration contracts; it does not call a real model. diff --git a/docs/mp4.md b/docs/mp4.md new file mode 100644 index 0000000..52a954e --- /dev/null +++ b/docs/mp4.md @@ -0,0 +1,153 @@ +# MP4 workspace evidence + +MP4 sources join the existing Workspace KB and Graph publication pipeline. +They do not introduce another data surface.

Videos without an audio stream are +marked `no_audio`; silent audio can legitimately return zero speech segments. + +Copy the relevant settings from `.env.video.example` into your configuration, +filling the empty vision API URL/key first.

Configure embeddings +and the main Codex host as usual; video vision credentials are separate. +The example does not enable a working API endpoint and is not loaded automatically. + +## Ingest and retrieve + +1. In a write operation, call `workspace_prepare(path)` for a task-local source + directory. MP4 files appear in its SHA-256 inventory. +2. Call `video_prepare(path_to_mp4)`.

Page through `kb_video_read(bundle_id, offset, limit)` until `next_offset` is + null. View relevant images using `kb_video_frame(bundle_id, frame_id)`. +4.

Each + triple needs `properties.video_bundle` set to the prepared bundle ID and + `properties.video_evidence`, for example: + + ```json + {"subject":"Revenue","relation":"amount","object":"42 million", + "properties":{"video_bundle":"","video_evidence":[{"frame_id":"frame-0001"},{"segment_id":"speech-0000"}]}} + ``` + +5. Include the MP4 `{uri, version, triples}` entry in `workspace_publish` along + with other document assertions. Publish with `surfaces=["kb","graph","db"]` + (or the required subset). Use explicit empty triples if no semantic + relationships exist. A preprocessing failure is not an empty source. +6. Start a pinned read operation. `kb_search` returns `bundle_id`, `frame_id`, + timestamps, source version and PNG checksum in chunk metadata. The video + read tools fetch layout/speech or original PNGs for the same revision. + +Text evidence reads load the bundle manifest without scanning frame images. +Ordinary `kb_video_frame` reads only the selected PNG and verifies those exact +bytes before returning them; it does not hash every other frame. DataSpace +evaluation trusts immutable inputs and prepared media, skipping repeated source +and image checksum comparisons. Bundle completeness, task membership, safe image +paths and the image size limit still apply. First-build fingerprints remain in +metadata; this does not enable automatic image viewing. + +The Python `Workspace.update` API follows the same contract and accepts +`graph_sources`. For MP4 Graph publication, it requires explicit assertions; +it does not create a second conversational agent. Snapshot mode needs entries +for all documents; incremental mode can reuse unchanged source assertions. +When changing video processing configuration, prepare again and resubmit video +assertions. Legacy live `kb_add_file`, `kb_add_path` and CocoIndex imports remain +text/document pipelines; use Workspace publication for MP4. + +## Evidence and lifecycle + +Graph includes deterministic `has_frame`, `has_layout` and `aligned_speech` +edges. Semantic triples receive validated frame/speech locators, source hash +and pipeline version. Multiple frames can support the same assertion. +Relation vocabulary and semantic triple limits do not suppress structural edges. +Frame alignment uses slide onset (`start_s`); PNG evidence records the actual +decoded frame time (`capture_s`). Words are assigned by midpoint. Missing word +timestamps use explicit segment overlap and may refer to more than one frame. + +Both snapshot and incremental storage persist bundle references in their +manifests/checkpoints. Changed/deleted sources replace the current revision's +KB and Graph data; retained revisions, leases, rollback and migration preserve +their old media. GC protects retained bundle references. Unreferenced media +has a 24-hour grace period for preparation before publication; expired bundles +and their stale snapshot checkpoints are eligible for cleanup. + +The cache key includes source URI/hash, pipeline and nonsecret configuration. +Increment `video.cache_revision` when replacing model weights or changing a +server-side model behind the same name. Credentials are neither written into +bundles nor hashed as cache content. Failed preprocessing leaves no complete +bundle, and failed publication leaves the previous Workspace head readable. + +## Method and limits + +The design follows [zhezh/kddcup2026_champion](https://github.com/zhezh/kddcup2026_champion) +at commit `bdc874fc4260e3565ae0dce041728fdf5b376709`: packet-size bursts, +settled-slide frames, Hiccup layout OCR, local tiny/medium Whisper and timeline +alignment. Its repository contained no license file when reviewed. DataMind's +adapter is independently implemented; no champion source files are vendored. +Its private gateways, static-ffmpeg downloader, remote ASR service and +question-specific voting/answer adjudication are not imported. Hiccup is +represented as validated JSON arrays, avoiding executable parsing. + +Packet-burst detection is a heuristic for presentation videos. Periodic guard +frames improve coverage of hard cuts but do not guarantee capturing every +visual event. Full-resolution PNGs remain available for visual verification. +ASR and OCR may be wrong; no accuracy claim follows from a successful import. +Limits on duration, bytes and frame count fail explicitly rather than silently +dropping evidence. OCR token truncation, malformed layout, missing models and +image checksum failures also fail explicitly in ordinary mode. Vision request retries/timeouts +use the existing model client; offline CPU transcription has no API dependency. + +HTTP upload's existing 25 MiB limit is unchanged. For larger videos, place the +file in an allowed server-side workspace directory. MP4 support does not change +SQLite workspace input support, SQL row limits or existing column normalization. + + +## Direct question answering and OCR format + +`video_prepare(path, ocr=True, asr=True)` can be used directly without publishing +KB or Graph. `ocr=False` and/or `asr=False` skip only that explicitly selected +operation; manifests report `disabled`. Frame image extraction and direct +`kb_video_frame` viewing remain available, including without auxiliary models. +The flags participate in the bundle cache identity. A failed enabled operation +still fails rather than publishing a silently partial bundle. + +`video.ocr_response_format` supports the original `hiccup`, opt-in `json_schema` +for providers that enforce it, and `text`. In `text` mode, the model +transcribes text and Python constructs/serializes the Hiccup wrapper. This +removes model-generated JSON syntax/schema failures, but provides no guarantee +of OCR accuracy or structured page layout. Inspect original PNGs for charts, +layout and verification. Refusals/empty responses, truncation and transport +failures remain explicit errors. Select `json_schema` only when your provider +supports and enforces the requested schema; enforcement is provider-dependent. diff --git a/pyproject.toml b/pyproject.toml index ebd4e46..8af074f 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -78,6 +78,9 @@ Repository = "https://github.com/OpenDCAI/DataMind" Issues = "https://github.com/OpenDCAI/DataMind/issues" [project.optional-dependencies] +dataspace = ["ijson>=3.2,<4"] +# faster-whisper still passes metadata_errors, removed by PyAV 19. +video = ["av>=14,<19", "faster-whisper>=1.1,<2", "Pillow>=10", "opencc-python-reimplemented>=0.1.7"] # Historical v0.1 capability modules only; main.py/server.py now delegate # to the shared Codex CLI/HTTP host.
