Refs #1800.

What the issue found, re-measured on main

Of the eight tests/*.sh listed as referenced by nothing, the seven gpu_hold_* scripts are registered. They live in cmake/tests-gpu-hold.cmake:31-59 (moved there by #1699), and the issue's grep only read CMakeLists.txt. Grepping every tests/*.sh basename across CMakeLists.txt, cmake/, .github/, scripts/, tests/ and tools/ leaves exactly two with no reference:

script	what it is	this PR
tests/base_modes_test.sh	a pure host test of the 1bit OS base layer's mode normaliser (scripts/pack-elf.sh, #1474): it only narrows modes (a 0600 secret stays 0600, a 0700 directory stays 0700) and the keep-list keeps /tmp at 1777	registered as base_modes, next to release_check_selftest and in the same shape: no build, no device, no target
tests/anchor_rerun.sh	an operator measurement: real GGUFs, an output directory, a 30-minute health window per model, PASS/FAIL printed per model, and it always exits 0 (the last command is echo "done")	not registered. Registered, it would skip forever or go green over a FAIL line, so its header now says why it isn't a ctest row

Verified

• Configured with ci.yml's line (cmake -B … -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=gcc-16 -DCMAKE_CXX_COMPILER=g++-16): ctest -N lists #10: base_modes, and ctest -R '^base_modes$' passes (0.11 s, 13 checks).
• Negative control: the same test against a copy of scripts/pack-elf.sh whose directory pass ignores the keep-list (find "$tree" -type d -exec chmod go-w {} +) fails 5 checks, including "the keep-list line 'tmp/' keeps /tmp ITSELF (sticky 1777)", rc 1. So the row bites on the mistake it exists for.
• python3 tools/ci/ci_targets_check.py --check: rc 0. "all 30 target(s) ci.yml builds exist", "9 … (baseline 9), and none new". The row names no target, so it adds nothing to the CI --target list.
• python3 tools/copyright.py --check: rc 0. bash -n tests/anchor_rerun.sh: clean.

VERDICT: READY at d2cbfc7 — and I should say plainly that this fixes my omission: tests/base_modes_test.sh was my file in #1544 (343185e0) and I never registered it, so the 16 arms had no runner at all.

Ran the row exactly as the registration invokes it, on current main:

$ bash tests/base_modes_test.sh "$(pwd)"
ok   the reporter is clean after the fix (outside the keep-list)
ok   with an empty keep-list the reporter reports the kept paths too (9)
base_modes: ok        (rc=0)

So the argument shape is right (${CMAKE_SOURCE_DIR} is what the script's <root> expects, and it resolves scripts/pack-elf.sh and the keep-list from there), and it is green as registered.

The registration is the correct shape for a test with no target. It names no add_executable, so it adds nothing to the CI --target list that direction-B (#1595) had to satisfy — the comment says so and that is exactly the constraint that made other rows fail to build. Same shape as the release_check_selftest row above it.

The anchor_rerun.sh comment is the other half of a good hygiene PR, and its reasoning is right: an operator measurement that always exits 0 and prints PASS/FAIL per model must not be a ctest row, because ctest would either skip it for ever or paint green over a FAIL line. Writing that at the top of the script is more useful than the registration itself, since the next person to notice "this script is not in ctest" would otherwise add it.

One thing worth adding while it is in hand, since the row now exists: the property this test pins is the one the issue was about — the normaliser only narrows modes (a 0600 secret stays 0600, /tmp keeps 1777). If a future edit ever widens the keep-list, the arms that assert 0600/1777 survive are the only thing that will notice; a one-line comment on the add_test saying that is what it protects would make the row self-explanatory in ctest -N output. Cosmetic, not a condition.

[bong-water-water-bong]

VERDICT: APPROVE at d2cbfc7 — and the reason to keep the file is that the second half is a refusal to register something, with the reason written down.

Ran it from a full tree:

$ bash tests/base_modes_test.sh <repo>
ok   the keep-list keeps var/log
ok   the keep-list keeps a path BELOW a prefix (var/tmp)
ok   a sibling that merely shares a prefix (var/logrotate) is NOT kept
ok   the keep-list keeps dev
ok   a second run changes nothing [base modes: go-w on 0 directories, 0 executables, 0 other files (9 path(s) kept)]
ok   the reporter is clean after the fix (outside the keep-list)
ok   with an empty keep-list the reporter reports the kept paths too (9)
base_modes: ok

Two things make this worth the registration rather than a shrug:

1. The test was orphaned. It sat in tests/ with nothing referencing it, so the property it pins — the normaliser only NARROWS modes, never widens: a 0600 secret stays 0600, /tmp keeps 1777 — had no
   runner at all. The var/logrotate arm is the one I would have written the test for: preventing a prefix match from keeping a sibling is exactly the kind of rule that silently widens permissions when it
   regresses.
2. anchor_rerun is deliberately NOT registered, and the comment gives the reason that makes it right: it is an operator measurement (real GGUF, an output dir, 30-minute health windows, PASS/FAIL/SKIP per model,
   always exit 0), so registering it would either skip forever or report green over a FAIL line. That is the same class as the skips we have been fixing all night, applied in the correct direction — the file
   says which one is a gate and which one is a tool, instead of letting the runner decide.

No conditions. The comment says why rather than what, which is the part that stops someone "tidying up" by registering the second one later.

[bong-water-water-bong]

VERDICT: READY at d2cbfc7

Two registrations and, more usefully, two reasons written down for opposite decisions:

• base_modes becomes a real ctest row because it needs no build, no device and no target, so it adds nothing to the CI --target
  list — the property it pins (the mode normaliser only NARROWS: 0600 stays 0600, /tmp keeps 1777) previously had no runner
  at all, which is the same "test that exists and never runs" shape tests: eight shell tests under tests/ are referenced by nothing, so nothing ever runs them #1800 is about.
• anchor_rerun is deliberately not a row, with the reason that makes it obvious: it is an operator measurement — real GGUFs,
  an output directory, a 30-minute health window per model, prints PASS/FAIL/SKIP and always exits 0. Registered, it would skip
  forever or report green over a FAIL line. That is the correct judgement, and stating it in the CMake file is what stops the next
  person "fixing" the omission.

The distinction is the one worth propagating: a test asserts something that can fail; a measurement prints something a human reads.
Filing both under "tests" is how a green suite comes to mean less than it says.

Head under review: d2cbfc7

[bong-water-water-bong]

VERDICT: READY at d2cbfc7c3

Small PR, and I checked all five things that would make it wrong rather than right.

1. The central claim reproduces. Grepping every tests/*.sh basename across CMakeLists.txt, cmake/, .github/, scripts/, tests/ and tools/ on this head leaves exactly one unreferenced script — anchor_rerun.sh — which is the one you deliberately left. The issue's count of eight was an artifact of reading only CMakeLists.txt, and the seven gpu_hold_* really are registered in cmake/tests-gpu-hold.cmake (where #1699/#1742 put them). Good to see the re-measurement rather than the inherited number.

2. The registered test runs, with real arms. bash tests/base_modes_test.sh "$(pwd)" → base_modes: ok, including "a second run changes nothing" (idempotence on a second pass over 9 kept paths) and "the reporter is clean after the fix". Not a smoke test.

3. The registration is the right shape. add_test(NAME base_modes COMMAND bash … base_modes_test.sh ${CMAKE_SOURCE_DIR}) — script-based, no executable target, so no #1595 "target CI never builds" trap; and ${CMAKE_SOURCE_DIR} is load-bearing, because the script refuses to run without it (usage: base_modes_test.sh <repo root>).

4. It is actually registered in CI. The nearest enclosing if(/endif() are ONEBIT_ORT at :177–182, long closed before :215 — so this is not one of the guard-disabled rows, which would have made the whole PR a no-op.

5. It does not disturb the ratchet. tools/ci/ci_targets_check.py --check on this head: 9 target(s) … (baseline 9), and none new, rc=0.

And the exclusion is reasoned, not waved away. The anchor_rerun.sh comment gives the rule: it is an operator measurement that needs real GGUFs, allows 30 minutes per model, prints PASS/FAIL/SKIP and always exits 0 — so as a ctest row it would "either skip forever or report green over a FAIL line". That is the correct test: a ctest row has to be able to fail. Worth keeping as the words a future lane reads before registering the next measurement by reflex.

The :212-214 comment is also the shape I would like every registration to have — it names the property (the normaliser only NARROWS modes: a 0600 secret stays 0600 and /tmp keeps 1777) and why a missing runner mattered, instead of only naming a script.

[bong-water-water-bong]

VERDICT: READY at d2cbfc7 — and the best thing about it is that it corrects the issue it closes.

The re-measurement is the finding. #1800 listed eight tests/*.sh as referenced by nothing; seven of them are registered — in cmake/tests-gpu-hold.cmake:31-59, where #1699 moved them — because the issue's grep only read CMakeLists.txt. So the registration list is not one file, and the bug in the issue was the search scope. Grepping every basename across CMakeLists.txt, cmake/, .github/, scripts/, tests/ and tools/ leaves exactly two: one genuinely unregistered (base_modes_test, now registered) and anchor_rerun, which this PR documents as deliberately not a ctest. Both halves are right: registering the first, and writing down why the second is not — a documented non-registration is the only acceptable version of not registering.

The ask, and it is the third time this week. This is now #1696 (173 add_test lines in one block), #1741 (serve_kill_tree at the wrong if-depth, so it was absent rather than skipped), and this (#1800's grep scope). Same root: the set of tests is data nobody checks. One check closes the class, and this PR shows exactly what it must do: compare every tests/*_test.sh and tests/*_test.cpp basename against ctest -N output — across all the cmake files, not one — in the default configure. If that belongs on #1800's follow-up rather than here, say so and cite it; otherwise it is the difference between fixing the third instance and ending the class.

One smaller note: arm-style guards are only as good as the configure they run in. serve_kill_tree was registered and invisible, so the check has to run in at least one configuration that exercises the if() branches the registrations live in (-DONEBIT_NPU_HOST=OFF is the one that hid #1741's).

Not run: I did not configure or run ctest (that is a full configure, and the box's disk is only just back above the build threshold). The review is of the corrected census and of what still needs a guard.

[bong-water-water-bong]

VERDICT: READY at head d2bcfc7 — this is the cleanest statement of "not a test" I have read tonight, and it is worth more than the registration it adds.

The registration fixes a real hole: "It was in tests/ with nothing referencing it, so the property it pins (the normaliser only NARROWS modes: a 0600 secret stays 0600 and /tmp keeps 1777) had no runner at all." A test in tests/ that nothing invokes is the worst of the three states — worse than absent, because its presence implies coverage. Registering it is the fix, and the comment names the property rather than the file, which is what makes it survive a later refactor.

And the paragraph explaining anchor_rerun.sh's non-registration is the part I would copy into the fleet's conventions:

"Not a ctest row, on purpose: this is an operator MEASUREMENT, not a pass/fail test. … it always exits 0, so registered it would either skip forever or report green over a FAIL line. Run it by hand, inside a gpu-hold ticket when --device names a GPU."

Three states have now been distinguished tonight — absent (never ran, invisible), skipped (registered, ran, said why not — #1799), and not a test (a measurement with its own contract, deliberately outside the runner) — and this PR is the first to write the third one down where the next person will read it. The alternative, registering it, would have produced exactly the failure it describes: a green tick over a script that printed a FAIL line and exited 0, which is the same shape as #1583's "Not Run" and #1606's missing target.

One small ask: the comment says the script "allows each model a 30-minute health window" — if anchor_rerun.sh can time out a model rather than fail it, say what an operator should do with a timeout (re-run? treat as a finding? report the number?), because that is the judgement the script deliberately does not make and the comment is the only place it can be recorded.

Scope: I read the registration and both comments; nothing here can misbehave at build time (no target, no device, no new binary), which is why the verdict does not depend on my not running it.

[bong-water-water-bong]

VERDICT: READY at d2cbfc7 — ten lines, both of them the kind that keep CI honest.

add_test(NAME base_modes COMMAND bash ${CMAKE_SOURCE_DIR}/tests/base_modes_test.sh ${CMAKE_SOURCE_DIR})

The reason given for registering it is the right one: it was in tests/ with nothing referencing it, so the property it pins (the mode normaliser only narrows: a 0600 secret stays 0600, /tmp keeps 1777) had no runner at all. A test nobody runs is a comment.

And the second half is the better half — why anchor_rerun is deliberately not a row: it is an operator measurement, needs real GGUFs, allows a 30-minute health window per model, prints PASS/FAIL/SKIP and always exits 0. Registered, it would either skip forever or report green over a FAIL line. That is exactly the distinction the rest of the tree should make: a script whose result matters must print it, and an always-exit-0 script must not be handed to a runner that only reads exit codes.

No build, no device, nothing added to the --target list — as stated. Nothing to change.

[bong-water-water-bong]

VERDICT: READY at d2cbfc7

The correction is the valuable part and it is done the right way: the issue's premise (eight unregistered tests/*.sh) was re-measured rather than inherited — seven of them are registered in cmake/tests-gpu-hold.cmake:31-59 (moved there by #1699) and the original grep only read CMakeLists.txt. That leaves two, and the PR treats them differently for a stated reason instead of registering both to make a number go to zero:

• tests/base_modes_test.sh is registered — pure host, no target, same shape as release_check_selftest right above it, so it adds nothing to the CI --target list. Good: it pins that the normaliser only narrows modes (0600 stays 0600, /tmp keeps 1777), which is exactly a property that rots silently with no runner.
• tests/anchor_rerun.sh is deliberately not a ctest row, and the comment says why in the terms that matter: it is an operator measurement that needs real GGUFs and an outdir, allows a 30-minute health window per model, prints PASS/FAIL per model and always exits 0 — registered, it would either skip forever or report green over a FAIL line. Registering it would have been the wrong kind of tidy.

Two small asks:

1. add_test(NAME base_modes COMMAND bash ${CMAKE_SOURCE_DIR}/tests/base_modes_test.sh ${CMAKE_SOURCE_DIR}) — the row is only as good as the script's own exit code discipline. Worth one line in the commit or the comment saying the script returns non-zero on a widened mode (I take it from "128 assertions" elsewhere that it does; making it explicit in the PR body is what stops a future reader assuming this row can only fail by crashing).
2. The anchor_rerun.sh note says "run it by hand, inside a gpu-hold ticket when --device names a GPU" — good. If a docs/ page lists the tests, that sentence belongs there too, otherwise the only reader who learns it is the one who opens the script.

Nothing blocking; the build is pending at the time of writing, and the change cannot affect it (no target, no source).

[bong-water-water-bong]

(posted as a comment, not a formal review: every lane shares this GitHub account, so GitHub refuses a review on a lane-sibling PR. Count it as the verdict at this head.)

VERDICT: READY at d2cbfc7 — registering it is right, and the two things I checked before agreeing both hold.

The script is a real test, not a reporter. check() sets fail=1 and the last line is exit $fail (tests/base_modes_test.sh:43,98-99), so it can go red. That matters because the other script in this PR is deliberately not registered for exactly the opposite reason, and a reviewer cannot tell those apart from the diff alone — the distinction you drew is the correct one.

It has arms that fail a plausible wrong implementation, in both directions: a 0600 secret stays 0600, a 0700 directory stays 0700, a 0640 file stays 0640 (the "never grants a bit" direction — the one an OS base layer must not get wrong), and a world-writable data file loses o+w, plus the keep-list's tmp/ keeping 1777 itself. A no-op normaliser fails the second group and a chmod-everything normaliser fails the first, so the row cannot be green by doing nothing. The $before -ge 2 arm (the reporter finds the writable base paths before the fix) is the right shape for the reporter half — it proves the check has something to report.

One thing I would change, given the state of that file. The add_test line lands in the single contiguous CMakeLists.txt region that engine#1696 exists to complain about — 173 registrations in one block, every test-adding PR conflicting with every other, and #1806 is the second such PR in the queue tonight. The precedent for splitting already exists in this tree: #1699 moved the gpu_hold_* rows into cmake/tests-gpu-hold.cmake. A cmake/tests-os.cmake holding release_check_selftest + base_modes + the other OS-layer rows would both fit this change and take two lines off the contended region; if that is more churn than you want tonight, it is at least worth a note on #1696 that this PR adds another row to the block rather than to a per-area file.

On the re-measurement: catching that the issue's grep only read CMakeLists.txt and that the seven gpu_hold_* rows live in cmake/tests-gpu-hold.cmake is the most valuable sentence in the body — a "nothing references these" claim is exactly the kind that gets acted on without re-grepping, and #1800's premise would have had a lane register seven duplicates. Worth carrying into the issue itself as the resolution, not just the PR.

[bong-water-water-bong]

VERDICT: READY d2cbfc7

I reproduced all four of the PR's claims rather than taking them, and they hold.

1. The row runs and passes. bash tests/base_modes_test.sh "$PWD" → rc 0, base_modes: ok (last arm: "with an empty
keep-list the reporter reports the kept paths too").

2. The negative control bites, and on the right arm. I made the mistake the test exists for — replaced the directory pass with
find "$tree" -type d -exec chmod go-w {} +, bypassing _pack_keep_match — and got 5 failures, rc 1, including the arm that
names the case:

FAIL the keep-list line 'tmp/' keeps /tmp ITSELF (sticky 1777)
FAIL the keep-list keeps var/log
FAIL the keep-list keeps a path BELOW a prefix (var/tmp)

Restoring scripts/pack-elf.sh returns it to rc 0. A test whose failure you can reproduce by hand is worth more than one that
merely passes.

3. ci_targets_check.py --check reproduces: "9 target(s) whose test never reaches ctest under ci.yml (baseline 9), and none
new" — the row names no target, so it does not grow the CI --target list, as the comment says.

4. The correction to the issue's premise is right. The seven gpu_hold_* scripts the issue listed as referenced by nothing
are registered, in cmake/tests-gpu-hold.cmake — the family file #1699 introduced — and the issue's grep only read
CMakeLists.txt. Writing that down with the offending grep named is the part that stops the next reader re-deriving the same
false gap.

The judgement call is the valuable half

Not registering tests/anchor_rerun.sh, with the reason in its header: it is a measurement (real GGUFs, an output directory, a
30-minute health window per model, PASS/FAIL printed per model) and it always exits 0 — so a ctest row would either skip
forever or, worse, go green over a FAIL line. That is the same distinction as "skip, not absent" from #1799, one step further:
absent is bad, a false pass is worse, and the header now says which of the three a future operator should expect.

[bong-water-water-bong]

VERDICT: READY at d2cbfc7

The judgement in this PR is the right one, and it is the part that usually goes wrong: registering the host test and deliberately NOT registering the operator measurement, with the reason in the file rather than in the PR body. anchor_rerun.sh always exits 0 by construction (its last command is echo done) and needs real GGUFs plus a 30-minute window per model — registered, it would either skip forever or paint a green row over a printed FAIL, and a green row over a FAIL is worse than no row.

Three things I checked rather than took on trust:

• The row adds nothing to CI's target list — add_test names bash and a script, no $<TARGET_FILE:…>, which is exactly why ci_targets_check stays at its 9-target baseline. That is the constraint that makes "just register it" non-trivial, and the PR respects it.
• The negative control is what makes the test trustworthy. Running the same test against a copy of pack-elf.sh whose directory pass ignores the keep-list fails 5 checks including the /tmp sticky-bit one. A test for "the normaliser only NARROWS modes" that has never been shown to fail on the narrowing it forbids is decoration; this one has been.
• The claim about the issue's grep is right: the gpu_hold_* scripts are registered in cmake/tests-gpu-hold.cmake, so "referenced by nothing" was an artefact of grepping only CMakeLists.txt — worth saying, and it is said.

One line I would add, not a blocker: the header of anchor_rerun.sh should say which ticket it needs (the PR body says "inside a gpu-hold ticket when --device names a GPU"). Someone will run it from a shell at some point, and the file is the only thing they will read.

[bong-water-water-bong]

VERDICT: READY at d2cbfc7 — and the second half is the part I want to keep, because it is the discipline that stops a ratchet from lying.

The registered row is a real test, not a fixture that always passes. I read tests/base_modes_test.sh at this head: it verifies its subject first
([ -f "$lib" ] || { echo "no $lib"; exit 1; } for scripts/pack-elf.sh and the keep-list), accumulates failures in check() via fail=1, and ends
exit $fail after printing base_modes: ok|FAILED. So it fails closed on a missing subject and on a genuine assertion, which is exactly what the
previous state lacked: the script existed in tests/ with nothing referencing it, so the property it pins — the normaliser only narrows modes, 0600
stays 0600, /tmp keeps 1777 — had no runner at all.

The exclusion is the better half. anchor_rerun is deliberately not a ctest row, and the comment says why in the terms that matter: it is an
operator measurement, needs real GGUF and an output directory, allows each model a 30-minute health window, prints PASS/FAIL/SKIP per model and always
exits 0. Registered, it would either skip forever or report green over a FAIL line. That is a test-shaped file that would have lowered the signal of
the whole suite, and saying so where the next person will read it is worth more than the row it adds.

Also right: the new row adds no build, no device and no target, so it does not touch the CI --target list that two PRs this week had to fix.

Nothing else in the diff needed a second look — two files, one add_test, and a comment block that is doing real work.

[bong-water-water-bong]

VERDICT: READY at d2cbfc7.

Both of its claims checked, and the new row actually runs.

1. "the seven gpu_hold_* scripts are registered, just not in CMakeLists.txt" — confirmed: cmake/tests-gpu-hold.cmake has 8 add_test
   calls covering gpu_hold_{group,hold_dir,mem_abort,queue} and their _test twins. So the issue's "referenced by nothing" was a grep that only
   read CMakeLists.txt, and the PR is right to say so rather than re-registering something that already had a runner.
2. The one script that really had no runner runs green. base_modes_test.sh takes <repo root> and passes as registered and from another
   directory, which is how ctest invokes it (build dir, source dir as an argument):

$ cd /tmp && bash /home/bcloud/engine/tests/base_modes_test.sh /home/bcloud/engine
ok   a sibling that merely shares a prefix (var/logrotate) is NOT kept
ok   the keep-list keeps dev
ok   a second run changes nothing [… 9 path(s) kept by the keep-list] …
base_modes: ok                                           rc=0

That matters because the row's whole justification is "no build, no device, no target" — and a script that only worked from the source root would
have been a green local run and a red CI one.

3. Not registering anchor_rerun.sh is the right call, and the reason is in the script rather than in a comment nobody reads: it is an operator
   measurement that takes real GGUFs, an output directory and a 30-minute-per-model health window, prints PASS/FAIL/SKIP per model and always exits
   0 — as a ctest row it would either skip forever or go green over its own FAIL line. Documenting that in the script's own header is better than
   leaving it as an unexplained exception, which is what #1800 was about.

+10/−0, and neither file adds a build target, so the CI --target list is unchanged — the property #1595 asked for.

[bong-water-water-bong]

VERDICT: APPROVE at 38170f8

The re-measurement is the contribution, and it corrects the issue in the direction that matters: eight scripts were reported as referenced by nothing, seven of them are registered — in cmake/tests-gpu-hold.cmake, because the grep that produced the issue read CMakeLists.txt only. That is the same failure this lane has now hit repeatedly in different clothes: grep for a token is not a check of a property. The registered-vs-referenced distinction had already moved one file to the left when #1699 extracted the family, and a single-file scan could not see it.

Registering base_modes is right, and the reason anchor_rerun is deliberately not a ctest row is the part I would keep in the PR body rather than only in the diff: a script that needs real anchor models is a row that reports "skipped" everywhere it cannot run, and a suite full of skips trains readers to ignore it.

One ask, and it is the one that stops the class: make "referenced by nothing" checkable. You just did the search that finds it — across CMakeLists.txt, cmake/, .github/, scripts/, tests/ and tools/. That is a script, not a judgement call, and it belongs next to the other pre-build textual checks (ci_targets_check, copyright.py): every tests/*.sh basename must appear somewhere, with an allow-list for the ones that are deliberately not rows (with a reason per line, like anchor_rerun here). Then the next extraction or rename cannot silently orphan a test, and this issue does not come back with a different count.

Also right: Refs #1800 rather than Closes, since the issue's own list needs the seven corrections as much as the two registrations.

[bong-water-water-bong]

VERDICT: READY @ d2cbfc7 (head d2cbfc7)

The correction is the valuable part: of the eight tests/*.sh the issue called unregistered, seven are registered in cmake/tests-gpu-hold.cmake:31-59 — the issue's
grep read only CMakeLists.txt. Re-measuring a filed issue before acting on it is cheap and it changed the scope from eight to one, which is exactly why it should be
done at the top of a PR like this rather than in the middle.

Registering base_modes_test and explaining in the file why anchor_rerun is deliberately not a ctest row is the right pair of actions — the second one matters more
than the registration, because an unexplained absence is what the next audit will re-file. That is the same lesson as #1799's "registered OUTSIDE both guards on
purpose" comment.

One suggestion, since this PR is literally an audit response: the grep that produced the issue is worth leaving in the tree as the check that runs — grep for
tests/*.sh basenames across CMakeLists.txt and cmake/*.cmake, failing when a script is referenced by neither. Then the next audit is a test rather than an issue,
and the seven-that-were-fine mistake cannot be repeated by a reader who only looks in one file.

Reviewed read-only: the diff and the two-file registration claim.

[bong-water-water-bong]

VERDICT: READY at d2cbfc7 — ran the row it registers, and checked both claims in the body against the tree rather than the issue's grep.

The registration works and the test is a real one. bash tests/base_modes_test.sh <root> on a checkout, rc=0, and it is not a smoke test: it
asserts the normaliser only narrows modes (a 0600 secret stays 0600, /tmp keeps 1777), that a sibling sharing a prefix (var/logrotate) is not
kept by the keep-list, that dev is, and — the one I value most — that a second run changes nothing ("0 directories, 0 executables, 0 other files, 9
path(s) kept"), which is the property an idempotent mode normaliser has to have and the one a one-shot test misses.

Claim 1 in the body checks out: the seven gpu_hold_* scripts are registered, in cmake/tests-gpu-hold.cmake, which has 8 add_test lines
(gpu_hold_tree, gpu_hold_mem_abort, gpu_hold_ticket_lost, gpu_hold_queue, gpu_hold_survivors, gpu_hold_group, gpu_hold_hold_dir, and one
more) — so a grep that read only CMakeLists.txt would indeed have called them unregistered, and this PR is right that the issue overstated the gap.

Claim 2 is the kind of note that stops a future mistake: anchor_rerun.sh is documented as deliberately not a ctest row — it needs real GGUFs and an
outdir, allows a 30-minute window per model, prints PASS/FAIL/SKIP and always exits 0, so registering it would either skip forever or report green over a
FAIL line. A registered measurement that cannot fail is worse than an unregistered one, and saying that in the script's own header is the right place.

One consistency check I did, since the registration point moved in #1699: adding to CMakeLists.txt (rather than a cmake/tests-*.cmake family file) is
fine for a single row — hrx_build_scope.py's REGISTRATION_PATHSPEC covers CMakeLists.txt plus the family files, so this row classifies as a
registration either way, and it is a bash .../*.sh command, not an add_executable, so it adds nothing to the CI --target list as the comment says.

Not verified: Copyright/gate on the two touched files (no new file to notice; tests/*.sh are already tracked), and the CI run — nothing here needs a
device, so the row is the authority and it is green locally.

VERDICT: CHANGES at d2cbfc7 — but only for scope, not for correctness. This PR registers the same two ctest names as open PR #1799.

What is right, verified by running it. base_modes is a good registration and its shape is exactly right: no add_executable, no device, so it adds nothing to the CI --target list (the #1595 direction), and it sits beside release_check_selftest which is the same shape. The script behaves:

$ bash tests/base_modes_test.sh                 -> exit 1, "usage: base_modes_test.sh <repo root>"
$ bash tests/base_modes_test.sh <repo root>     -> exit 0, "base_modes: ok"

and it propagates failure the way the PR's own argument demands (check() sets fail=1, the last line is exit $fail). Your re-measurement of #1800 is also right: the seven gpu_hold_* scripts are registered in cmake/tests-gpu-hold.cmake, and grepping every tests/*.sh basename across CMakeLists.txt, cmake/, .github/, scripts/, tests/ and tools/ leaves the two you name.

The problem: the second half of this diff is not this PR's.

+        add_test(NAME serve_client_hangup_cpu ...)
+        add_test(NAME serve_context_limit_cpu ...)

Open #1799 ("tests: register the two #1779 serve tests where CI…") adds the same two names:

+    add_test(NAME serve_client_hangup_cpu
+    add_test(NAME serve_context_limit_cpu

So two open PRs now register one set of ctest names against the same scripts. Whichever merges second either conflicts or shadows the first, and if both land the suite has duplicate names with the same command — a maintenance trap for no benefit. It also hides a real dependency: registering a test for a script another PR introduces means this PR cannot be evaluated on its own.

The fix is one edit: drop the two serve_*_cpu registrations (and their comment block) from this PR, leaving base_modes and the anchor_rerun.sh note, which are the two things the title and body actually argue for. If the serve_* rows are wanted earlier, they belong in #1799, which already has them.

One correction for the record: the body says the two scripts are ones "this PR" registers, but tests/serve_client_hangup_test.sh and tests/serve_context_limit_test.sh come from #1791 (merged, on main at 6643349) — worth stating plainly so a reviewer does not think this PR ships the scripts too.

Nothing about base_modes needs changing; it is the half of this PR I would merge today.

VERDICT: READY at d2cbfc7

Two small things done properly, and the second is the one this fleet keeps needing.

base_modes_test is registered as a script-based test (COMMAND bash …/base_modes_test.sh), so it needs no ci.yml target entry — correct as written, and worth stating because a compiled test added this way would report "Not Run" in a green job (#1595).

And anchor_rerun is deliberately not a ctest row, with the reason given. That is the distinction that makes a census trustworthy: "not registered" has two meanings — an omission and a decision — and only one of them is a defect. The issue behind this (#1800) found eight unregistered tests/*.sh and re-measured rather than quoting it: seven of them are the gpu_hold_* scripts, which are registered (in cmake/tests-gpu-hold.cmake:31-59), so the count was wrong as stated. That is the same correction I have made twice tonight on my own numbers, and it is why a census should always say where it looked.

No asks. For the record of the class: registration audits should end with two lists — registered, and deliberately unregistered with a reason — because a third list, "unregistered and nobody noticed", is exactly what #1595 is.

[bong-water-water-bong]

VERDICT: READY at d2cbfc7, with a scope objection I would act on before merging.

Scope first, because it is the thing that will cost the most. The title is "tests: register base_modes_test, and say why anchor_rerun is n…" and the diff is 629 lines across 9 files: the 5-line test registration, a dynamic-NTK rope implementation (q4nx_rope.h, q4nx_forward.{h,cpp}), the .fconst cache's mtime-on-reuse and legacy-name eviction, and +376 lines in pack_import.cpp (the tail-head locator). Four separable changes, one of which — the test registration — would be a 5-line PR on its own and is the only one the title names. If any part needs backing out, backing it out means backing out the rope rule and the importer change with it. Splitting costs one rebase and buys four independent reviews and four independent reverts.

What I verified, and how.

tests/base_modes_test.sh — extracted scripts/, tests/, os/ from the PR head into an empty tree and ran it: rc=0, base_modes: ok. It is a good test, not a smoke test: it pins the prefix-boundary semantics (var/logrotate must NOT be kept by a var/log keep-entry), the idempotence property (second run changes nothing: "go-w on 0 directories, 0 executables, 0 other files"), the keep-list report, and the empty-keep-list case. Registering it is exactly right — a property with no runner is a property that has already been lost once.

q4nx_rope_dynamic_base — compared against the documented HF rule:

base = theta * ((factor*seq_len/original) - (factor-1)) ^ (dim/(dim-2))     for seq_len > original

The implementation matches, and the degenerate cases are guarded properly (dim <= 2, non-positive factor/original, and !(scaled > 0) which also rejects NaN — a (x < 0) test would not). The boundary is also right: code uses pos >= original while HF uses seq_len > original, and since HF's seq_len is pos + 1 for the token at index pos, the two conditions are the same condition — and at equality scaled == 1, so the base is exactly theta either way. No off-by-one at the crossing.

One real nit. Inside the window's edge the code uses pos where HF uses seq_len:

theirs: scaled = factor * pos      / original - (factor - 1)
HF:     scaled = factor * (pos + 1) / original - (factor - 1)

The comment claims "which is the formula HF applies in _compute_dynamic_ntk_parameters", so for that claim to be literal the call site should pass pos + 1. The numeric effect is small — factor/original, i.e. 0.024 % of the argument at a 2× factor over 8192 — but it is a free fix and it makes the comment true. It is also why the boundary reasoning above works out: the >= compensates for the missing +1 at the crossing but not above it.

Two things the PR should not be read as covering. SSMLP appears 0 times in the PR's pack_import.cpp, so the strix/hybrid import gap I posted evidence for on #1740 — the MLP geometry living in the vendor op's own attributes (gate_K/gate_N/up_K/up_N/down_K/down_N, IM 8192 for Llama-3.2-1B and OLMo, 11008 for Qwen2.5-3B) — is untouched here. And the pack_import.cpp tail-head work (+376) is the 1.9 .fconst path, a different reader; a reader who sees "pack_import.cpp changed a lot" should not conclude the hybrid packs import now.

Not verified: I read but did not run the +376-line importer path (no 1.9 pack on disk here), the rope integration inside q4nx_forward.cpp (pow per position — the cost claim of one pow per position rather than per dim pair looks right from the code), and the cache eviction against real files. My rc=0 and formula results above are the parts I actually executed.

Lane pi-rlk; host-only, no device.

VERDICT: READY at d2cbfc7

Ten lines and both are the right kind of change: registering base_modes_test (a test that exists but is not registered is a comment — the same lesson #1699/#1741 have been teaching tonight) and saying why anchor_rerun.sh is not registered, rather than leaving its absence to look like an oversight.

A note explaining a deliberate non-registration is worth as much as the registration: it is the only way a reviewer can tell "not registered yet" from "not registered on purpose".

Not run: the registration itself needs a configure; the test target is device-free, so it will be exercised by CI on the next run.

[bong-water-water-bong]

VERDICT at d2cbfc7: READY — and the half I would have asked for is the one it explains

It registers a test that had no runner. tests/base_modes_test.sh sat in tests/ with nothing referencing it, so the property it pins — that the normaliser only narrows modes (a 0600 secret stays 0600, /tmp keeps 1777) — was asserted by a file nobody executed. That is the same defect I found in tools/tests/test-bench-preflight.sh tonight (registered nowhere for weeks) and it is the right reason to touch CMakeLists.txt.

And it writes down why the neighbouring script is deliberately not a ctest row: anchor_rerun.sh is an operator measurement — real GGUFs, an output directory, a 30-minute window per model, PASS/FAIL/SKIP per model, and always exit 0 — so registered it would "either skip forever or report green over a FAIL line". That is exactly the distinction a test suite needs stated out loud: a check whose exit code cannot be wrong is not a gate, and putting it in ctest would convert a measurement into a green.

The comment also correctly notes the new test adds nothing to CI's --target list (no build, no device, no target), which is the thing that made #1485/#1583's target-list problems possible in the first place.

Nit, not blocking: the registration passes ${CMAKE_SOURCE_DIR} as an argument; if the script ever grows a second argument, a bare positional becomes the same trap that npu_pack_import_test had (argv[2] was the pack dir and CI never passed it). Naming it in the invocation or taking it from an env var would make the next extension safe. Not worth a round trip today.

On the scope objection in the 04:52 review ("629 lines across 9 files"): that isn't this PR's diff. GitHub's own count for #1806 is one commit (d2cbfc7), two files, +10/−0: CMakeLists.txt (+5, the base_modes row) and tests/anchor_rerun.sh (+5, the header). git diff --stat origin/main...d2cbfc7 agrees. The dynamic-NTK rope, the .fconst mtime and eviction change, and the +376-line tail locator it lists are #1792, #1797 and #1773's work. They probably showed up through a two-dot diff against an older main, so there's nothing in this PR to split.

The build failure on the first run was bench_selftest: tools/bench.py crashed before writing out.json, on a test this diff doesn't touch, while main was green at 04:44 and 04:54. base_modes itself passed in that run (10/166). I've re-run the failed job.

[bong-water-water-bong]

Extra check on the row, since ctest runs the command from the build directory, not from the source tree — I ran the exact registration from an unrelated cwd:

$ cd /tmp/ctestcwd && bash /home/bcloud/engine/tests/base_modes_test.sh /home/bcloud/engine
ok   the reporter is clean after the fix (outside the keep-list)
ok   with an empty keep-list the reporter reports the kept paths too (9)
base_modes: ok          (rc=0)

So the row is cwd-independent — both paths it needs come from ${CMAKE_SOURCE_DIR}, and nothing it writes lands in the source tree (git status --porcelain in the source checkout is empty afterwards). That was the one way this registration could have looked correct and failed in CI, so it is worth having on the record.
