The v0.4.0 release commit claimed the [tool.uv.sources] entry "never reaches consumers". Measured against the pushed tag in clean environments, that is wrong in one direction and understated in the other: - uv, installing this package from git, DOES pick the guard up from the tag automatically. uv reads pyproject.toml when it builds from the source tree, so the source applies to the consumer too, not just to development here. - pip does not read it, and fails outright: "No matching distribution found for llm-ingestion-guard<0.3,>=0.2". The guard must be installed from its own tag FIRST. Verified that the guard-first order then installs cleanly and that the shipped adapter runs against the real guard in that environment. What did hold is the part that matters for the pin: the built wheel carries `Requires-Dist: llm-ingestion-guard<0.3,>=0.2`, so the range is still the declared dependency and the git URL is still a channel. README now states the pip order as the default instruction, with the uv shortcut beside it, because a consumer hitting the resolution error would otherwise read it as a broken release.

# llm-ingestion-okf
|
||
|
||
Shared ingestion library for OKF (Open Knowledge Format) bundles.
|
||
|
||
Status: phases 1 and 2 are implemented. Phase 1 (spec-based ingestion) covers
|
||
manifest validation, the `file`/`sql`/`http` connectors, deterministic
|
||
materialization, index generation, and the golden fixture suite under
|
||
`examples/`. Phase 2 adds the bundle inbox (`process_inbox`) and
|
||
external-bundle import (`import_bundle`), both against an **injected** persist
|
||
gate, with `llm_ingestion_okf.guard_adapter` wiring that gate to the real
|
||
guard (see below). One phase-2 item is deliberately outstanding: binary
|
||
extraction (`pdf`/`docx`/`xlsx` behind the `[extract]` extra) is unimplemented,
|
||
so those types are rejected fail-fast. Phases 3–4 are planned (see
|
||
`docs/plan/`).
|
||
|
||
## Planned scope (v1)
|
||
|
||
The library provides three entry points for getting content into an OKF
|
||
bundle:
|
||
|
||
1. **Spec-based ingestion.** An implementation of the normative ingest
|
||
specification owned by `portfolio-optimiser-commons`: manifest →
|
||
`file`/`sql`/`http` connector → deterministic materialization of
|
||
`ingest-{id}.md` concept files → index generation. Zero model calls in the
|
||
run path; output is reproducible byte-for-byte against golden fixtures.
|
||
2. **Bundle inbox.** A drop directory where common file types are converted
|
||
to OKF concept files. All file-type→text extraction lives in this library:
|
||
`md`, `txt`, `csv`, `json`, and `html` are handled by the stdlib core;
|
||
`pdf`, `docx`, and `xlsx` require the optional `[extract]` extra and are
|
||
rejected fail-fast without it. Extracted text passes the security gate
|
||
before anything is persisted.
|
||
3. **External bundle import.** Import and merge of third-party OKF bundles:
|
||
each concept is assessed via the security gate, and only concepts that
|
||
pass are merged, materialized, and linked into the index.
|
||
|
||
## Boundary: security is delegated
|
||
|
||
Security is owned by the sibling package
|
||
[`llm-ingestion-guard`](https://git.fromaitochitta.com/open/llm-ingestion-pipeline-security)
|
||
(pinned `>=0.2,<0.3`). The division is strict:
|
||
|
||
- **guard** answers "is this content safe to persist?" — scan, sanitize,
|
||
quarantine, fail-secure, provenance stamping.
|
||
- **this library** does the plumbing — connect a source, materialize a
|
||
deterministic OKF bundle, generate the index.
|
||
|
||
No security functionality is reimplemented here.
|
||
|
||
### What is gated today: read this before trusting a door
|
||
|
||
- **Door A (`materialize_bundle`) is ungated.** It calls nothing before
|
||
writing to disk and writes what it is given. A caller materializing
|
||
untrusted content is responsible for gating it.
|
||
- **Doors B and C (`process_inbox`, `import_bundle`) gate through an adapter
|
||
you pass in.** Each takes a `gate` argument; the flow hands it the content
|
||
and obeys the verdict, refusing to persist anything that does not clear the
|
||
guard's non-blocking floor — including a disposition it does not recognise,
|
||
and (at Door C) a concept the gate returned no verdict for. What it cannot
|
||
do is check that your adapter is a real guard: a permissive stub approves
|
||
everything, and the flow will believe it.
|
||
|
||
`llm_ingestion_okf.guard_adapter` is the adapter over the real guard, and the
|
||
only module here that imports it — importing the package itself does not:
|
||
|
||
```python
|
||
from llm_ingestion_okf import process_inbox
|
||
from llm_ingestion_okf.guard_adapter import inbox_gate
|
||
|
||
result = process_inbox(inbox_dir, bundle_dir, "2026-07-25T12:00:00Z",
|
||
okf_type="reference", gate=inbox_gate)
|
||
```
|
||
|
||
Two properties of that adapter are worth knowing before you rely on it.
|
||
It screens the **exact bytes it persists** — the guard's `prepare_input`
|
||
bookend prepares text for a model call, which this library never makes, so
|
||
only `screen_output` is used and the screened string is the written string.
|
||
And it **refuses rather than repairs**: a file carrying an invisible
|
||
zero-width or bidi character is rejected, not silently stripped and written.
|
||
Door B screens under the untrusted-upload policy, so any finding at all is
|
||
held back rather than persisted.
|
||
|
||
This section is stated plainly because earlier wording ("calls the guard at
|
||
every persist gate") described the intended end state in the present tense,
|
||
and a consumer reasonably read it as safe-by-default.
|
||
|
||
## Roadmap
|
||
|
||
The library is built in four phases so that every known OKF surface in the
|
||
ecosystem is eventually covered. Each phase has a detailed plan with
|
||
verification criteria:
|
||
|
||
1. Spec-based ingestion (Python) with byte-exact golden fixtures —
|
||
[plan](docs/plan/phase-1-door-a.md).
|
||
2. Bundle inbox and external-bundle import (Python), guard-gated —
|
||
[plan](docs/plan/phase-2-doors-b-c.md).
|
||
3. Configurable bundle contract (types, layers, frontmatter sets, and
|
||
reserved-file policy as configuration), enabling stricter bundle
|
||
profiles such as `strict-v1` —
|
||
[plan](docs/plan/phase-3-configurable-contract.md).
|
||
4. A `node/` half: a zero-dependency Node/ESM package (importable and
|
||
CLI-invokable, vendored per consumer) providing bundle checking, index
|
||
generation, inbox processing, and document conversion for the OKF
|
||
second-brain plugin ecosystem. The Python and Node halves share the OKF
|
||
contract and fixture suite, not code —
|
||
[plan](docs/plan/phase-4-node-half.md).
|
||
|
||
## Non-goals
|
||
|
||
- Verdict/feedback machinery from the method specification (stays in the
|
||
consuming repositories).
|
||
- Embedding- or retrieval-layer functionality.
|
||
- Security functionality, in either runtime — that is always
|
||
`llm-ingestion-guard`'s domain.
|
||
|
||
## Requirements
|
||
|
||
Python 3.10+, and exactly one runtime dependency — the security boundary,
|
||
`llm-ingestion-guard>=0.2,<0.3`. Everything else is stdlib.
|
||
|
||
That guard is not on a package index yet, so **with pip, install it first** —
|
||
otherwise installing this package fails with `No matching distribution found
|
||
for llm-ingestion-guard`:
|
||
|
||
```
|
||
pip install "llm-ingestion-guard @ git+https://git.fromaitochitta.com/open/llm-ingestion-pipeline-security.git@v0.2.0"
|
||
pip install "llm-ingestion-okf @ git+https://git.fromaitochitta.com/open/llm-ingestion-okf.git@v0.4.0"
|
||
```
|
||
|
||
With uv, one command is enough — `uv pip install "llm-ingestion-okf @ git+…@v0.4.0"`
|
||
resolves the guard from the tag on its own, because uv reads the
|
||
`[tool.uv.sources]` entry in this project's `pyproject.toml` when it builds
|
||
from the source tree. Both paths were measured on 2026-07-25.
|
||
|
||
A git URL is a PEP 508 direct reference and pins one exact tag, so it is an
|
||
install-time *channel*, not the pin: the range above stays the declared
|
||
dependency — the built wheel carries `Requires-Dist:
|
||
llm-ingestion-guard<0.3,>=0.2` — and resolves normally once the package index
|
||
exists. The optional `[extract]` extra (pdf/docx/xlsx parsers) is not
|
||
populated yet. The planned Node half targets Node/ESM with zero npm
|
||
dependencies.
