feat(cli): okf project/consume/check/skill, and a generated skill with no path into a checkout

Browse source 
The reading direction existed only for someone standing in a clone. `consume`,
`contract_check` and `skill` moved from `tools/` into the package and are
reachable as `okf consume`, `okf check` and `okf skill`; `okf project` is new
and does the whole thing in one command.

The red measurement: a consumption skill generated from a checkout carried 4
lines naming that checkout by absolute path, 2 of them the commands the skill
tells a reader to run. It now names `okf consume` and `okf check`, and a test
asserts this repository appears in it nowhere, with a known-positive so the
zero is a measurement rather than a search that could not find.

The `tools/` files stay as ALIASES, not re-exports: a re-export binds copies of
the names into a second module object, so a caller patching one patches a
binding the implementation never reads. Two tests that monkeypatch okf_consume
went green again only under the alias. Every published reproduction block runs
unchanged.

The template and docs/consumption-contract.md (the section 7.4 known-positive)
are force-included into the wheel from the file they are authored in, so both
travel with the commands that cannot run without them and there is still one
authored copy of each.

Step 0, before any of it: okf build's default gained Arm E (--table-grid),
with --no-table-grid as its opt-out. The default moved to D plus F earlier the
same day on Arm F's published 5 of 12 -- a figure measured with Arm E ON.
Without it the fold has no joined table to fold, and the shipped default scored
2 of 12 with docx 0 of 3. Measured on the operator's folder: 30 md / 15
concepts on the new default against 43 / 28 without Arm E.

Install measurement from a fresh uv tool install, empty folder, this repository
nowhere on PYTHONPATH: 5 documents in, 15 concepts out, 0 references to tools/
in the generated skill, okf check conformant (15 rules, 0 findings).

Deviation stated rather than hidden: the order asked that
tests/test_okf_consume.py be left untouched. Two assertions in it read a PATH,
which is the one thing this work changes. Both were moved and the second made
stronger -- it now asserts every command the README recipe names is a
subcommand the CLI registers, which a file existing on disk never proved.

Suite 1414 -> 1427. ruff clean, mypy --strict clean over 21 files.

"""Check a consumption skill and one pre-pass payload against the contract.
#!/usr/bin/env python3
"""Thin entry point. The implementation is `llm_ingestion_okf.contract_check`.
`docs/consumption-contract.md` is normative prose. Prose has no test, so this
command reads the mechanically checkable half of it: the payload shape (SS 3, 5,
6, 7, 8) and the fixed vocabulary a conformant `SKILL.md` must carry (SS 4, 6).
It moved into the package on 2026-09-08 (O5): the generated consumption skill's
check step named this file by absolute path into a checkout, so the one command
that tells a reader whether their payload conforms was unreachable from an
install. The command is now `okf check`, on PATH.
**What it cannot see, said here rather than implied.** The division of labour
(SS 2) and the prohibitions (SS 9) are properties of a RUN -- whether an agent
went looking for context the pre-pass withheld, whether a retrieval tool was
pointed at the verdict layer. No static check reaches them. Conformance here is
the floor, never the proof, and a green run means the payload carries what a
claim would have to rest on -- not that the claim was made honestly.
This file stays because the published reproduction blocks name it, and a
measurement whose command no longer runs is a measurement nobody can repeat.
**Every rule has its own code.** One "invalid" verdict over fourteen different
defects is a diagnostic no caller can act on. The codes are the contract's
paragraphs made addressable.
**The report carries denominators**, because the contract requires them of its
consumers and a checker exempting itself would be stating the rule it breaks:
how many rules ran, over how many excerpts and withheld entries.
Exit codes are three, not two: 0 conformant, 1 non-conformant, 2 the check did
not run. Collapsing 2 into 1 would report an unread file as a failed check.
It lives outside `src/`, so it never enters a wheel and no consumer's install
surface changes because it exists.
No logic here, deliberately: a second copy of a contract rule is a second thing
that can pass while the shipped one fails.

"""Instantiate the consumption skill template for ONE named OKF bundle.
#!/usr/bin/env python3
"""Thin entry point. The implementation is `llm_ingestion_okf.skill`.
`skills/okf-consume-template/SKILL.md` is a template whose own rule is that a
copy leaving a `<PLACEHOLDER>` unfilled "is not configured, it is unfinished".
Filling it by hand is what produced `skills/okf-consume/` for one corpus. This
command does the same thing for any bundle, from values it measures rather than
values someone remembered.
It moved into the package on 2026-09-08 (O5). The objection that kept it out --
a wheel-installed `okf skill` would emit a command pointing at a file the wheel
does not carry -- was about what the GENERATED skill names, and it was answered
by changing that: the emitted commands are `okf consume` and `okf check`, names
on PATH, and both moved into the package in the same step.
**Why a generator rather than one generic skill.** Measured 2026-09-08: the
contract checker passes the UNFILLED template against a real payload (exit 0, 15
rules, 0 findings), and passes a skill built for a different bundle against this
one's payload. So the checker cannot tell the two forms apart, and the choice
could not be made on conformance. It was made on what the skill has to state:
§ 5's denominators, § 7.6's breaking point and § 6.4's conditional-field list
are all per-bundle numbers. A generic skill can either leave them as holes -- the
template's own definition of unfinished -- or carry another corpus's numbers,
which is worse, because a stated cost that is false for this bundle is a
measurement failure and not merely a gap. Instantiating is what makes them true.
And with several bundles connected at once, a generic skill has nothing to
select on: each generated skill carries the bundle's id in its own name.
**Zero model calls, zero network, no clock.** The same bundle bytes produce the
same skill bytes. It lives outside `src/`, so it never enters a wheel and no
consumer's install surface changes because it exists -- and a wheel-installed
`okf skill` would emit a command pointing at `tools/okf_consume.py`, which the
wheel does not contain.
Exit codes are three, as elsewhere in this chain: 0 the skill was written, 1 the
run happened and refused, 2 the run did not happen.
This file stays because `docs/2026-09-07-okf-konsumskill-maaling.md` names it,
and a measurement whose command no longer runs is a measurement nobody can
repeat.
