`OKF_V0_2` landed in D2 but was unreachable from outside: no door took a
profile. This threads one through, keyword-only behind the `*` the signature
already carried, so every three-positional call site stays source-compatible —
which is what po-claude asked for, and what makes additivity a property of the
signature rather than something a consumer measures.
Nine sites, not the ~6 STATE claimed. The load-bearing one is the call at
materialize.py:378: the CONTENT phase has accepted `profile` since D2, but the
call site never passed one, so A-E3/A-E4/A-E5 were all unreachable. The other
eight are the disk phase (ownership glob, index name, index maintenance,
concept filenames) plus `generated_filename` in manifest.py.
`link_in_index` is public and called from all three doors, so it gets
`*, profile=DEFAULT` rather than having the lookup moved to the call site:
doors B and C keep exactly the behaviour they had, and which profile THEY own
stays an open question instead of being decided silently by a signature change.
Byte-neutrality is proven, not asserted: `OKF_V0_2.paths is DEFAULT.paths` and
`.index is DEFAULT.index`, and the golden suite is green. That identity is also
why six of the nine sites cannot be proven reachable by any shipped-profile
test — no assertion distinguishes two names for one object. A synthetic
test-only profile renaming the index and the concept files closes that gap, so
a site left on `DEFAULT` fails by name rather than passing quietly.
Scope stated rather than glossed: the profile does NOT reach manifest type
validation (`manifest.py:198` still reads `DEFAULT.types`; measured equal to
`OKF_V0_2.types`, so nothing is hidden today), and `STRICT_V1` is not supported
here — its index policy sets three judging fields the materializer does not
honour. Both are named in the docstring.
No `okf_version` anywhere: that lands once, at D5, when the §12 placement
question closes.
550 tests pass (was 542).
