Commons settled on 2026-08-01 that MCP is an extension of the `http` source
family, not a fourth family (`shared/ingest-spec.md` §4). This implements it
with ZERO schema change and zero spec amendment.
The transport discriminator lives in `base_url`, not in new manifest fields:
the shared library rejects unknown manifest keys fail-fast, and we consume it
pull-only at a pinned v0.3.1, so `server_ref`/`tool` as fields would have meant
a spec amendment plus a library release. It buys nothing — the library already
joins `base_url` + `/` + `query`, so `mcp+stdio://<server_ref>` + `<tool>`
reproduces exactly the two-part structure the (now stale) reference plan wanted.
Staying inside the family INHERITS what a fourth family would have had to write
and could have forgotten: the §8 network grant (measured to fire before any tool
call), the `max_rows` cap, §5 verbatim fenced rendering, and the §7 provenance
stamp. The discriminator gates rather than labels — `mcp_get` refuses a URL it
does not own, so an MCP transport can never quietly serve an `https://` manifest
and leave the bundle's provenance claiming a transport that was never used.
Parsing is string-based, not `urlsplit`-based: `urlsplit().hostname` lowercases
the host, which would silently break the case-sensitive env lookup `server_ref`
depends on.
`ingest.py` is untouched — it is AST-guarded mcp-free, so the transport lives in
its own module and is opt-in at the call site. `ingest_mcp.py` imports the open
`mcp` protocol client but never `agent_framework`, keeping the seam D7-portable.
Load-bearing, six mutations all measured RED: detach the scheme guard · make the
refusal unconditional · swap parsing to `urlsplit().hostname` · skip non-text
content instead of raising · force `allow_network=True` · smuggle in a MAF
import. Both source files restored byte-identical (`shasum -c`) after each.
Honesty: `stdio_call_tool` (the real stdio path) is written but never executed
end to end — every test injects a canned tool call, so the suite spawns no
subprocess and opens no socket. No golden fixture, and MCP stays unwired in the
optimiser run path. Stated in docs/extending.md rather than implied away.
555 -> 578 tests; ruff + mypy green.

Door A (manifest -> connector -> deterministic materialization -> index) is no
longer implemented here. src/portfolio_optimiser/ingest.py becomes a thin
consumer seam over the shared library, git-pinned to v0.3.1 on the same Forgejo
channel portfolio-optimiser-claude uses. Net -626/+385; ingest.py 599 -> 145 lines.
shared/ingest-spec.md remains the normative spec: the library implements it, it
does not replace it. Spec changes continue to go via commons.
Acceptance criterion met and proven: all three golden bundles (file/sql/http)
are byte-exact before and after, including the idempotence re-run. examples/ and
shared/ carry ZERO modifications -- the fasit was not adjusted to fit.
The rejection set was verified equivalent, not assumed: all 22 malformations the
repo's pydantic models refused are refused by the library, with typed codes
(okf_type_reserved, credential_embedded, extraction_id_duplicate, ...).
Test rebinding (invariants preserved, vehicle changed): the library has zero
runtime dependencies by design, so pydantic is unavailable to it.
ManifestV1.model_validate(dict) -> load_manifest_bytes(bytes); ValidationError ->
ManifestError; model_fields -> dataclasses.fields; PathSecurityError ->
SourceError(path_escape); ValueError -> MaterializationError(ingested_at_invalid).
Tests now also pin the refusal `code`, the library's documented stability
contract -- a sharper assertion than "some validation error was raised".
Two accepted behavioural deltas, recorded rather than silently dropped:
- Title whitespace is stored verbatim instead of collapsed at validation, so the
frontmatter title and the index label are no longer guaranteed identical for
irregular whitespace. Both behaviours are spec-conformant (the spec is SILENT;
the old one was a repo-local pinned decision). Queued as a commons-amendment
candidate so both stacks pin the same answer. Goldens unaffected.
- The section 8 audit log moves to logger llm_ingestion_okf.materialize. Nothing
in the repo consumed the old channel.
Also: the `type` discriminator is no longer a dataclass field, so the spec
cross-check asserts it explicitly -- without that line the swap would have
silently narrowed the test.
New tests/test_ingest_library_seam.py pins the seam itself: the restated section 5
stamp formula against the stamp the library actually writes (the one place the
adapter does not purely delegate, since v0.3.1 exposes no stamp helper), the
local-only allow_network default, the list[Path] unwrapping, and a guard that the
adapter never regrows local Door A machinery. All four verified RED when detached,
as were both golden regressions under a byte-level render mutation.
Door A is UNGATED: it calls no guard before writing to disk. Gating untrusted
content remains the caller's responsibility (guard wiring still planned).

Findings 4-7 from the 2026-07-02 status analysis, per the session plan (S1):
- CHANGELOG rewritten truthfully (was: 'Plan phase - no framework code yet')
- README stack line names the split GA packages, not the agent-framework meta-package
- CLAUDE.md: MCP downgraded to extension point (in-process FunctionTool is the default seam)
- Verdict conflict semantics documented as chosen (store first-write-wins per id,
disk/wiki last-write-wins per file; full B10 taxonomy deliberately deferred)
- docs/extending.md: explicit 90%-principle cut-list (B10, B11, U12, U14, concurrent fan-out)
- .gitignore covers .trekexecute-progress-* (docs/.DS_Store was already untracked/ignored -
the plan's git rm --cached assumption was stale; no-op)
No code behavior changed (docstring only in verdicts.py). Suite 152/4 green, mypy clean,
ruff format --check clean.
