B-gate row 1's premise, made callable. Every path through the framework CLI constructs a chat
client, so an outside caller -- a human at a terminal, or an agent that is NOT po -- could not
reach a single run-path step without paying for a model. These four steps need no model at all.
One CLI, four subcommands, one core call each:
navigate-bundle --bundle-dir -> okf.navigate_bundle
cost-baseline --bundle-dir --project-id -> okf.derive_cost_baseline
retrieve-chunks --query --docs-dir [--top-k] -> datasource.retrieve_chunks
prepass-admit --payload --bundle-dir [--dimension] -> prepass.admit_payload
Each handler is a thin adapter: strings in, the SAME function the run path calls, JSON on stdout,
and an exit code that says what happened (0 ran, 2 malformed call, 3 the step refused, named).
A handler that computed anything of its own would be a second implementation of a run-path step,
and the outside caller would stop getting what the debate gets.
Dispatch is an explicit branch per command, not argparse's `set_defaults(handler=...)`: the table
hides the one thing a reader wants to see, and B-gate row 1 asks the same question of the source
(it walks the call graph from `main` down to the step's symbol), where a callable in a Namespace
is a hop neither can follow.
Probes (`tests/test_toolbox_doors.py`, 10 arms): each starts the door as a SUBPROCESS with the
subcommand in argv and asserts on what it wrote -- never by importing the core function, which is
the whole difference the gate exists to measure. The yardstick is outside the door in every arm:
the filesystem (navigate-bundle, including the one deliberate outside-bundle link), a table
transcribed from the priced fixture (cost-baseline), the in-process seam it must equal byte for
byte (retrieve-chunks), and the producer's own checked-in payload (prepass-admit). Every refusal
arm has an rc-0 control beside it.
`portfolio-optimiser-toolbox` is the THIRD console script, and the pin test now says why: it is
the door the other two cannot be used for. README and CLAUDE.md updated with the command and the
reason it exists; every documented invocation was run.
Row 1: 1 -> 5 of 17 (four subcommands + `gate`, which the class fix in e47be68 stopped rejecting
on a name technicality). No other row moved; exit 1.

Two commands are now part of the install surface a fresh clone gets from `uv sync`:
`portfolio-optimiser` (run:main) and `portfolio-optimiser-demo` (simulation:main).
Deliberately two of five main()s — costsim/hitl/preflight stay module-invoked; every
name here is a name the freeze has to carry. Pinned against the INSTALLED distribution's
metadata, not the TOML: a [project.scripts] line that has never been synced is a claim,
not a command. Measured: stdout is byte-identical across both invocation forms.
stderr (P4 pkt. 2), the session's open decision, resolved by measurement rather than by
preference. Damped: the round-cap notice only, via a filter on the emitting logger, keyed
on the message and installed by main() — never at import, so a library consumer keeps its
own logging config. NOT damped: the two ExperimentalWarnings. They fire while the package
__init__ imports run -> agent_framework, always before simulation's own imports and under
both invocation forms, so silencing them would mean filtering warnings inside the library
package on every consumer's behalf; they are pinned in pkt. 3 instead. A console-script
wrapper was rejected for a second reason: the two forms would then write different stderr,
and a byte-fasit would pin the command rather than the program. stderr 6 -> 4 lines.
A first implementation wrapped simulation's own agent_framework import in a scoped mute.
Measurement showed it can never fire — the package __init__ has already imported
agent_framework by then — so it was removed rather than left as a green-but-dead seam.
Load-bearing MEASURED against the whole suite, five mutations all red + green control:
remove [project.scripts] · typo the target · detach the main() call · make the filter drop
everything · install the filter at import time. The typo mutation also felled a test: the
resolve-assert re-checked the expected constant against itself, and now resolves what the
distribution actually installs. 775 -> 785 passed / 4 skipped.
