Four of the 37 scripts here have actually been watched to flip. That was recorded only as prose in each script's header, so answering "how many of these are real regression tests" meant a grep and a read, and the number could not be quoted. Every script now carries a top-level `proof:` key, one quoted line per piece of evidence, ` -- `. docent.js reads only the keys it names off the parsed document, so this costs a run nothing. tests/proof.js reads them and tallies, wired up as `make proof` in the shared docentTest.mk. It exits 1 on a malformed line, an unknown level, or a line left unquoted -- that last one because nearly every note names a ticket and a bare # in an unquoted YAML scalar silently truncates the sentence at the ticket number, which is how the first pass of this change lost half its text. The levels, weakest first: assertion-only, xfail, sandbox-ab, server-flip, caught-regression. Today that reads 31 / 2 / 0 / 3 / 1. nightly.sh now records the flips it finds. An xfail that PASSES is the best evidence this suite produces -- the same server, the same fixtures, the same script, one real build apart -- and until now it arrived as a red mail and was thrown away with the log 60 days later. It is appended to /hive/users/braney/docentNightly/flips.log, one line per script ever, outside the checkout because --update resets the tree. The mail says what to do with it. The three flips that already happened (rm38272 2026-09-06, rm36212 2026-09-09, rm38310 2026-09-10) were recovered from the old logs and seeded there by hand. Full suite run after the change: 37 scripts, all ok. refs #38252 Co-Authored-By: Claude Opus 5 (1M context) diff --git src/hg/utils/docent/tests/regress/rm27113.docent.yaml src/hg/utils/docent/tests/regress/rm27113.docent.yaml index 5ac4dae5793..dd92c272e04 100644 --- src/hg/utils/docent/tests/regress/rm27113.docent.yaml +++ src/hg/utils/docent/tests/regress/rm27113.docent.yaml @@ -25,30 +25,33 @@ # click 3 155,806,199-155,806,201 3 bases centre 155,806,200 # # A one-base drift at any click moves every window after it, and the last one is three # bases wide, so there is nowhere for it to hide.
