Meta Vens f68bd4099f testparse: jest names come only from "●" lines under a FAIL header; real jest fixtures
Jest without a TTY prints "FAIL jt/add.test.js" with one space; the parser
matched two, so a real jest load failure read ERROR, not UNVIABLE. The old
`^ +● ` denylist also named process.exit's "●  process.exit called with "1""
as a killing test (CAUGHT). Names now need a FAIL file header above them; a
crash with no named failing test is ERROR. The "no test counts recognised"
line names jest. The synthetic jest logs and mock are replaced by real jest
29.7.0 output captured on Yggdrasil from tools/fixtures/mutation-probe/jsr
(green, wrong, load, exit runs in logs/jest-real.log).

#!/usr/bin/env bash
# Sourced, not run. Reads a test-run log and says what it contains.

# tp_scan <log> one line per fact:
# FRAMEWORK <name> passed=<n> failed=<n> skipped=<n> (summed over the log)
# FAILED <test name> (one per failing test)
# LOADFAIL <file> (a test FILE that failed, with no test name:
# a module that did not load; jest also prints one for a file with failing tests)
# tp_sections <log> [max-lines] cargo failure sections ("---- name stdout
# ----"), each cut to its last <max-lines> lines (default 30)
#
# Frameworks: cargo test, dotnet test, vitest, jest, pytest. Anything else is
# simply not recognised; the callers treat "recognised nothing" as a fact to
# print, never as success.
#
# Owner: tools/stopgap/ygg-verify.sh (summary mode) and tools/mutation-table.sh
# (kill attribution). One parser, so a summary and a kill table cannot disagree
# about what failed. Written for mawk: no match() groups, no gensub.
