The gate had six legs and none of them read a docstring's own command line.
doc_command_check.py existed since 838750c but only as a tool: nothing on the
gate ran it, so a documented flag its parser never learned could land and
nobody read it. This is that leg.
doc-commands tools/doc_command_check.py --rev WORKTREE --fail
WORKTREE, not HEAD: the commit window is where a docstring is
edited. Measured at the worktree this lands in: 67 commands
over 19 oracle tools, 67 OK, rc 0.
doc_command_check.py learns --rev WORKTREE: tracked paths from `git ls-files`
(an untracked tools/x.py is not part of the commit this mode grades), bytes
from disk. Outside a work tree it is rc 2, not an empty clean run. Selftest
15 -> 18 cells: one document edited on disk but not committed is rc 0 at HEAD
and rc 1 at WORKTREE, and the flag it names is the edited one.
Three tools stopped defaulting to a fixed path on this host. verify.py,
selftest_sweep.py, write_probe.py, citation_resolve_check.py,
path_claim_check.py and doc_census_check.py now resolve DEFAULT_REPO from the
file's own location, so a bare run in a clone grades the clone.
Three selftests refuse unreadable input at rc 2 instead of reporting it as
failed content: tool_map (not a work tree), write_probe (no table), and
citation_resolve_check (no corpus). Each cell below them graded `repo`, so an
absent tree read as "your table is wrong".
Evidence, all measured on this tree before the commit:
verify.py --selftest 55 cells, 55 passed (docstring says 55)
doc_command_check.py --selftest 18 cells, 18 passed (baseline pinned 18)
tool_map.py --repo . --rev WORKTREE --check docs/TOOLS.md rc 0
verify.py --repo . 7 legs, 6 pass, 1 fault -- selftest-sweep,
tool_map's drift cell, which renders HEAD
and so cannot pass inside a commit window
tools/selftest_baseline.tsv re-pins doc_command_check.py 15 -> 18 cells.
DEFAULT_REPO was the absolute /root/troupe-standup, so a copy's
`--selftest` -- the invocation selftest_sweep.py uses, no --repo, cwd =
the tree under sweep -- graded the home checkout and reported the copy
clean. Derived from __file__ instead: the default is the checkout the
tool lives in. Measured on a clone at c3058d5 with drifted docs: before,
repo-less --selftest 20/20 rc 0 vs --repo . 19/20 rc 1; after, 19/20
rc 1 both ways.
Also in this commit:
- verify.run_leg: one elapsed-ms clock (_elapsed_ms) and one except arm
for TimeoutExpired/OSError, instead of three copies of the arithmetic;
- write_probe c13: roster read from FLAG_PROBES rather than a hardcoded
three, and selftest_sweep.py --write-baseline added to the table;
- docs/TOOLS.md: the selftest_sweep row grows the flags it now prints.
