Summary

A Stage A documentation accuracy sweep was run against the source. Two gaps were found and are fixed here:

• console_view.py exits with status 2 and prints the usage line when the environment ID is followed by further arguments (parseEnvironmentId requires exactly one argument). The README's Text rendering section and the module docstring said only "missing or is not an integer". Both now name the extra-argument case, and a main()-level test (test_a_further_argument_prints_the_usage_and_exits_two_without_reaching_viron) pins it. Before this, only parseEnvironmentId was tested for that case.
• usage_reporting.py sends unknown as the version when version.txt is missing, cannot be opened or is empty (readVersion() or UNKNOWN_VERSION; readVersion catches only OSError, so an undecodable file instead disables reporting through buildClient). The README's Usage reporting section now says so. That behaviour was already covered by test_missing_version_file_reports_an_unknown_version.

No production behaviour is changed. Only a docstring in console_view.py is edited.

No tracking issue: the gaps were found during the sweep.

Deferred issues

Every open issue was left for later because each one needs an owner decision or is too large for this cycle:

• environments.json does not record which Viron server an environment was created on #63: needs a decision on how environments.json should record the Viron server.
• A failed environment creation leaves the window open and shows no error, unlike a failed load #42: needs a decision on whether a failed creation should be handled like a failed load.
• The Viron submodule is pinned before Viron required bearer tokens, so Patchwork cannot reach a current Viron #41: needs a decision on whether to bump the submodule and add bearer-token support or keep the current pin. Changing the Viron submodule also needs explicit authorization.
• Decide whether per-location colours should be stable across frames #24: needs a decision on whether colours should stay stable or keep changing.
• Support drawing environments with multiple grids #2: support for multiple grids is a feature too large for one cycle.

Test plan

• python3 -m py_compile *.py passes
• python3 -m unittest discover -s tests passes locally: Ran 206 tests ... OK (Python 3.8; Viron is stubbed)
• The Tests workflow is green on this PR

Self-review rubric (head 97c20e6):

• Scope: PASS. All three files are needed: two README sentences, the matching console_view.py docstring, and one test that pins the newly documented exit path. There are no unrelated edits.
• Tests-new: PASS. No new functions were added. The newly documented console_view.main() path is covered by test_a_further_argument_prints_the_usage_and_exits_two_without_reaching_viron. The unknown version fallback was already covered by test_missing_version_file_reports_an_unknown_version.
• Tests-fix: not applicable, since this is not a bug fix. A mutation check was still run. Changing len(argv) != 2 to len(argv) < 2 in parseEnvironmentId made the new test and test_more_than_one_argument_gives_none fail. With the original code restored, all 15 tests in tests.test_console_view passed.
• Sibling structure: PASS. The new test copies the layout of the neighbouring test_a_missing_argument_..._exits_two_without_reaching_viron.
• Sibling renames: not applicable. Nothing was renamed.
• Docs: PASS. README.md is updated. create_environments.bat, up.bat and down.bat are untouched and not affected.
• Issue resolution: not applicable. There is no Closes #N, and the PR body says the gaps were found during the sweep.
• Manual validation: PASS. python3 -m py_compile *.py passed. python3 -m unittest discover -s tests ran 206 tests, all OK, locally. The Tests workflow run 42986061408 is green on 97c20e6. No rendering or Viron-service code was changed, so the live Viron run is not applicable.

One finding was fixed during review:

• README.md:304: the first draft said an unreadable version.txt falls back to unknown. readVersion catches only OSError. A file that cannot be decoded raises UnicodeDecodeError, a ValueError, which buildClient catches and answers with a disabled client. The wording was narrowed to "missing, cannot be opened or is empty" in 97c20e6, and the PR body was updated to match.

Out-of-diff observation, not acted on here: that decode-error path turns reporting off for the run and prints Could not configure usage reporting (...), rather than reporting unknown. Whether that difference is intended is not evident from the source. It was left out because changing it would be a code change in a docs cycle.
