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.
