Pull Request Checklist

  • PR title follows semantic convention
  • PR body includes Closes #7859
  • Tests added/updated: the t27b tests of loop-tools-gate pass locally
  • Specs changed → specs/tri/t27b/steward.t27 has no seal; gen/c/tri/t27b/steward.c is regenerated by t27c gen-c and byte-identical to it

Description

docs/reports/t27b_expectations.json stored counts (pass, pass_vacuous, not_pass) in its header. Those numbers are a total over entries, so every PR that adds a spec changed the same "pass" line. On 2026-10-08, #7579, #7586 and #7626 went dirty three times in two hours on that line alone, while their entries merged cleanly. The fpga jobs take an hour, so a spec PR could not outrun the t27b PRs landing on master.

The rule is written in t27 first. steward.t27 gains header_stored(field): a header field is stored only when it is not a total over the entries. counts is such a total; max_not_pass is not. The cap is the ratchet's promise (non-pass may only fall), and a PR that adds a pass entry does not move it.

Changes

  • specs/tri/t27b/steward.t27: header_stored, plus 4 tests and an invariant. 128 of 128 tests pass, 0 vacuous.
  • gen/c/tri/t27b/steward.c: regenerated by t27c gen-c.
  • scripts/tri_loop/t27b.py, a listed foreign exception (30 lines added): binds header_stored. dump_ledger writes only the fields the spec stores, and ledger_counts derives the totals bless prints. An unknown header field is an error.
  • docs/reports/t27b_expectations.json: the counts block is removed; nothing else changes.
  • scripts/ci/test_a_t27b_spec_cannot_move_silently.py (28 lines added): it read real["counts"] and now checks that there are none. New case: two branches that bless 1 and 2 new pass specs merge without a conflict, and with rules that store the counts the same merge conflicts (negative control).
  • docs/now/2026-10-08-t27b-ledger-derived-counts.md.

Testing

python3 scripts/ci/test_a_t27b_spec_cannot_move_silently.py   # PASS: 0 failure(s)
python3 scripts/ci/test_the_t27b_steward_decides_in_t27.py    # PASS
python3 scripts/ci/test_a_t27b_tick_reads_before_it_acts.py   # PASS
python3 scripts/ci/test_the_t27b_lab_heals_its_clone.py       # exit 0
python3 scripts/ci/test_the_t27b_gen_check_asks_the_lab.py    # exit 0
python3 scripts/ci/test_the_t27b_fuzz_judges_in_t27.py        # exit 0
t27c test-report specs/tri/t27b/steward.t27                   # pass 128, FAIL 0
t27c gen-c specs/tri/t27b/steward.t27 | cmp - gen/c/tri/t27b/steward.c
t27c suite --repo-root . --ratchet --corpus-only              # RATCHET CLEAN
python3 tools/check_json_parses.py                            # OK

The negative control was seen red before it was made robust. In its first form both branches added one entry each, so both moved "pass": 2 → 3 identically and git merged the stored counts cleanly. The control now uses 1 and 2 new entries, as real spec PRs do (#7579 added 1, #7586 3, #7626 18).

Review Notes

  • own-language will be red on this PR. scripts/ci/test_a_t27b_spec_cannot_move_silently.py is a hand-written .py with no entry in tools/policy/foreign-exceptions.txt, and its old assertion reads the removed field, so the test cannot stay as it is. The foreign-line budget passes (28 + 30 of 80, each under 40). The PR needs the owner's owner-approved-foreign label. I did not add it myself.
  • max_not_pass stays stored on purpose. A spec PR that adds a non-pass entry still moves it, but that is rarer, and it is a decision a reviewer should see.

…ed, as steward.t27 decides (Closes #7859)

docs/reports/t27b_expectations.json kept `counts` (pass, pass_vacuous,
not_pass) in its header. Every PR that adds a spec moved the same
"pass" line: on 2026-10-08 #7579, #7586 and #7626 went dirty three
times in two hours on that line alone while their entries merged
cleanly, and the fpga jobs take an hour.

- steward.t27: header_stored(field) -- a header field is stored only
  when it is not a total over the entries. counts is one; max_not_pass
  is not (the ratchet's promise; a pass entry does not move it).
  4 tests and an invariant; 128/128 pass. gen/c/tri/t27b/steward.c
  regenerated by t27c gen-c.
- t27b.py: binds header_stored and dump_ledger writes only the fields
  the spec stores; ledger_counts derives the totals bless prints. An
  unknown field is an error. No other hand-written foreign file moves.
- The committed ledger loses its counts block, nothing else.
- test_a_t27b_spec_cannot_move_silently.py: two branches that bless
  one and two new pass specs merge cleanly; with rules that store the
  counts the same merge conflicts (negative control).

own-language is red by design on this PR and needs the owner's owner-approved-foreign label. I did not add it myself.

  • What it names: scripts/ci/test_a_t27b_spec_cannot_move_silently.py: hand-written .py is forbidden. The file is not in tools/policy/foreign-exceptions.txt. Its old assertion reads real["counts"], the field this PR removes, so the test cannot stay as it is.
  • The rule itself is in t27 (steward.t27 header_stored). The only other hand-written file, scripts/tri_loop/t27b.py, is a listed exception.
  • The foreign-line budget passes: 28 added lines in the test and 30 in t27b.py, each under 40 and 58 of 80 in total. Checked locally with check_budget from gen/c/policy/own_language.c.
  • No re-run: the result is deterministic and only the label changes it.

duplicate-bodies is not this PR's. It has been red on master since a6d4e55 (#7490, run), and python3 tools/dupe_scan.py gives the same three groups on a clean master checkout:

  • LinkSection_text, LinkSection_data and LinkSection_bss in specs/port/bootstrap/src/compiler/LinkSection_text.t27 repeat link_text, link_data and link_bss from specs/fpga/linker.t27.

This PR touches neither file. No fix exists yet. The two ways out are reusing the linker's bodies, or python3 tools/dupe_scan.py --bless if the copy is deliberate, and either one is #7490's call. I did not re-run the check, because the result is deterministic.

duplicate-bodies is red on master since #7490; the same three-line

#7868 lands.

duplicate-bodies stays red on master after #7864 because of `assign 3`;
the same line as #7874, which no-ops once it lands.

The previous commit wrote an empty tools/duplicate_bodies_baseline.txt
(a git show of a branch that was not fetched). This restores it: master's
ledger plus the four lines of #7864 and #7874, nothing else
(dupe_scan: ok).

t27b-native-ratchet is not this PR's. It reports the same findings as master's latest completed run (81da894, job 113450310705): UNEXPECTED PASS 2 (weight_bram, tri/t27b/fuzz), MOVED 3 and UNLISTED 72. This head has UNLISTED 73. The extra one is specs/port/trinity/fpga/openxc7-synth/singularity_d6_top.t27, which landed on master after 81da894 (63a6bc1), so master's next run will show it too.

There is no traceback and no UNREADABLE verdict. The native ratchet reads the ledger without counts and judges it exactly as before, which is what this PR needs to hold.

No fix exists yet. The cure is a bless PR from a fresh lab run of master (tri t27b ratchet --bless --accept-new), which is outside this change. I did not re-run the check, because the findings are deterministic.

Check L1 TRACEABILITY is red because of my own commit: 5b9231c38 fix(dupe): restore the duplicate-bodies ledger emptied by 89c8d0326 names no issue. The other 3 of the 4 checked commits pass.

Fixing that message would mean rewriting a pushed branch, and force-push is forbidden in this workspace. The check is not required, and the PR is merged by squash under the title ... (Closes #7859), so the commit that lands on master carries the reference. Later commits on this branch will carry Refs #7859.
