Summary

A finding re-raised on a later push was routinely reported at a different level
than the one already sitting on the pull request. Measured across every
tinysweeper[bot] inline comment on tinyhumansai/tinysweeper and
tinyhumansai/tinymemory:

PR concern levels, in order
tinysweeper#89 a test comment misattributing the 8000-token failure medium → high → critical → high
tinysweeper#86 Pin dtolnay/rust-toolchain to a commit SHA medium, medium → high and medium in one run
tinymemory#13 verdict flipped CHANGES_REQUESTED → APPROVED in ten minutes

It is not cosmetic. fail_on and request_changes_at gate on severity, so a
medium↔high wobble flips the check-run conclusion and the review verdict with no
code change in between.

What changed

The schema had no rubric. severity was the only field in the response
schema with no description, and nothing in harness::prompt filled the gap —
the only mention of a "severity rubric" was the prompt-injection defence telling
the model not to let the repository change one that was never stated. Compare
rule, two fields above, which explicitly demands cross-run stability.
SHARED_RULES now carries a four-level rubric anchored on the consequence rather
than the topic, and says outright that confidence is the other question.

Layer 5 carried titles only. The model was shown what it said last time but
not at what level, so it could not have been consistent even when asked. Prior
findings are now listed as severity — title, carried in
ReviewedState::severities and read back off the comment's own priority badge
(forge wins over store — the comment is what the author is looking at, and it is
the copy a human can edit). The continuity contract asks for the level to be kept
unless the code moved.

Asking is not sufficient. Severity is not derived from anything checkable, so
two runs over identical code can disagree without either breaking a rule the model
was given. lane_proposal pins the level of any finding whose title it has already
seen, ahead of the conclusion and the verdict. Only an exact title match pins: a
reviewer that reworded the finding has re-made the case and may argue its own level.

Dedupe could not catch the repeats. The fingerprint hashes the model-authored
rule and the snippet the model chose to quote, so it only recognises a finding
described identically twice. src/eval/runner.rs on #86 carried one concern posted
three times over two pushes — lines 146, then 145 and 171 — under three
fingerprints. already_posted now also suppresses a finding anchored within three
lines of one of our own comments in the same lane and file. Asked last, needs both
findings placed on a line, and reads anchors off the live pull request so a comment
a maintainer deleted stops suppressing anything.

council::agree merged too much. Two findings on one file that neither could
place merged unconditionally — right for two copies, wrong for two defects.
.github/workflows/eval.yml on #86 yielded an unpinned dtolnay/rust-toolchain
and an unpinned Swatinem/rust-cache, both real, both unplaceable, and one was
thrown away. They now merge only on a matching rule id.

Behaviour changes

  • A finding already on the pull request is reported at the level it was first
    posted at, whatever the model says on a later push. A finding whose title
    changed is not pinned.
  • A repeat anchored within three lines of an existing comment from the same lane
    is suppressed as a duplicate. It still counts toward the check-run conclusion —
    suppression runs after the verdict, as before.
  • Two unplaceable findings on one file no longer merge unless they name the same
    rule.
  • ReviewedState gains severities, #[serde(default)] so records written
    before this deploy still load.

Validation

  • cargo fmt --all -- --check
  • cargo clippy --locked --all-targets -- -D warnings
  • cargo check --locked --all-features --all-targets
  • cargo test --locked1449 pass, 0 fail

Corpus re-recorded

SHARED_RULES and prompt layer 5 both changed, so every cassette missed and
eval::committed_test failed — the test doing exactly the job it exists for.
Re-recorded with tinysweeper eval run --record; nothing the corpus forbids
reappeared, and the suite is green.

Two things a reviewer should know rather than read off the scorecard:

The committed baseline is stale, and not because of this branch.
evals/baselines/current.json was recorded on z-ai/glm-5.2 on 2026-08-09.
2fbe77b switched both model tiers to deepseek/deepseek-v4-pro-0813 on
2026-08-13 without a re-record, so the baseline's config_digest
(6cdb039960d4f0e7) already disagrees with main's (f4167f5c587b5910).
digest_of hashes config only — no prompt text — so that difference is the
model switch, not this change. I left the baseline alone: refreshing it is a
decision about what the corpus claims, not a side effect of a prompt edit.

I cannot honestly attribute the false-positive count to this change. I
recorded the corpus twice off identical code, and ts-0045 scored 4 false
positives the first time and 7 the second. At n=1 per configuration the run-to-
run variance is larger than any effect a control run against main would have
measured, so I did not spend one — it could not have distinguished a regression
from noise. What is asserted holds: forbidden_hits is empty on both cases,
which is the regression the corpus exists to guard.

Tests

  • a_finding_keeps_the_severity_it_was_first_posted_at — two pushes over
    identical code, second model rates the same title low instead of high; the
    lane conclusion stays Failure. Verified non-vacuous by disabling the pin.
  • a_reworded_finding_may_still_argue_for_its_own_severity — the other half, so
    the pin cannot freeze severity across the whole pull request.
  • a_repeat_of_a_finding_that_moved_a_line_is_recognised_by_its_anchor, plus the
    three ways it must not match: another file, another lane, far away.
  • an_unplaceable_finding_is_never_suppressed_by_an_anchor.
  • a_level_that_already_drifted_is_pinned_to_the_earliest.
  • the_lane_is_taken_from_the_badge_and_not_from_the_prose — the badge parsers
    build their fixtures from render's own helpers, so a renderer change breaks
    the parser test instead of silently breaking production.
  • a_state_written_before_severities_existed_still_loads.
  • two_unplaceable_findings_on_one_file_corroborate_only_on_the_same_rule
    replaces the test that asserted the old unconditional merge.

A finding re-raised on a later push was routinely reported at a different
level than the one already on the pull request. On tinysweeper#89 one
unchanged concern read medium, then high, then critical, then high across
four pushes; on tinymemory#13 the wobble flipped the verdict from
changes-requested to approved ten minutes later with nothing between the
two but a re-review.

Four causes, all of them fixed here:

- `severity` was the one field in the response schema with no description
  and no rubric anywhere behind it, so every run re-guessed the level from
  nothing. `SHARED_RULES` now carries a four-level rubric keyed on the
  consequence rather than the topic, and separates severity from
  confidence explicitly.

- Prompt layer 5 listed prior findings by title alone, so the model could
  not have been consistent even when asked. It now lists them as
  `severity — title`, carried in `ReviewedState::severities` and read back
  off the comment's own priority badge, and the continuity contract asks
  for the level to be kept unless the code moved.

- Asking is not sufficient: severity is not derived from anything, so two
  runs over identical code can disagree without either breaking a rule.
  `lane_proposal` pins the level of any finding whose title it has seen,
  before the check-run conclusion and the request-changes verdict are
  computed. Only an exact title match pins — a reworded finding has
  re-made its case and may argue for its own level.

- Dedupe could not catch the repeats that caused the drift, because the
  fingerprint hashes the model-authored rule and the snippet the model
  chose to quote. `src/eval/runner.rs` on tinysweeper#86 carried one
  concern posted three times over two pushes, at lines 146, then 145 and
  171, under three fingerprints. `already_posted` now also suppresses a
  finding anchored within three lines of one of our own comments in the
  same lane and file — asked last, needing both findings placed, and read
  off the live pull request so a deleted comment stops suppressing.

Also narrows `council::agree`: two findings on one file that neither could
place used to merge unconditionally, which is right for two copies and
wrong for two defects. `.github/workflows/eval.yml` on tinysweeper#86 gave
an unpinned dtolnay/rust-toolchain and an unpinned Swatinem/rust-cache,
both real, both unplaceable, and one was thrown away. They now merge only
on a matching rule id.

`ReviewedState::severities` is `#[serde(default)]`: the field arrived after
records were in the store, and a record that failed to load would be
discarded and the pull request re-reviewed from scratch, losing exactly the
continuity it was added to keep.

📝 Walkthrough

Walkthrough

This PR adds severity-aware review continuity, anchor-based duplicate suppression, and rule-aware corroboration for unplaceable findings. It updates prompts, schemas, state persistence, documentation, tests, and evaluation cassettes.

Changes

Review continuity and deduplication

Layer / File(s) Summary
Prior review state and parsing
src/findings/prior.rs, src/state/types.rs, docs/modules/state/README.md
Prior reviews store finding severities and comment anchors. Badge parsing and positional matching support continuity across pushes. Existing serialized state remains compatible.
Severity-aware review orchestration
src/app/review.rs, src/harness/prompt.rs, src/harness/schema.rs, docs/modules/harness/README.md
The review pipeline carries continuity context, restores exact-title severities, suppresses covered anchors, and applies severity guidance during verdict processing.
Rule-aware unplaceable finding corroboration
src/council/agree.rs, src/council/agree_test.rs, docs/modules/council/README.md
Unplaceable findings corroborate only when normalized rule identifiers match. Tests and documentation cover distinct findings on one file.
Evaluation cassette updates
evals/cassettes/ts-0045-kernel-bypass-hallucination/*, evals/cassettes/ts-0068-description-anchored-to-code/*
Evaluation records include revised guidance, usage metrics, and recorded critique results for the affected scenarios.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 3b71a

The PR stabilizes finding severity across pushes, but identical titles used for different findings can still transfer severity across files or review lanes and change the resulting check or review verdict; the bounded risk should be fixed or explicitly accepted before merge.

tinysweeper 0.1.0

@tinysweeper tinysweeper Bot added the priority: p2 Soon. Real but survivable — a rough edge, a gap, a thing that will bite later. label Aug 16, 2026
Prompt layers 1 and 5 changed, so every cassette missed and the corpus
test failed on cassette misses — which is the test doing its job. No
finding forbidden by the corpus reappeared.

Recorded on deepseek/deepseek-v4-pro-0813, the configured primary. The
committed baseline was recorded on z-ai/glm-5.2 four days before 2fbe77b
switched both tiers to DeepSeek, so it is already stale against main and
its numbers are not comparable to these. Left alone rather than quietly
refreshed here: refreshing a baseline is a decision about what the corpus
now claims, not a side effect of a prompt change.

Exercise the new rule normalization behavior.

The implementation trims surrounding whitespace and ignores ASCII case, but this test uses identical rule strings. Add a differently formatted rule value so a regression to exact comparison fails the test.

Updated the first cassette in the ts-0045 kernel bypass hallucination eval to
reflect the higher input and output token usage of the new model version,
increasing the cost estimate accordingly. The rules_markdown value was also
refreshed to match the latest rule set.

Comment thread src/findings/prior.rs
The anchor fallback suppressed on lane, file and line proximity alone, so
two defects a few lines apart in one function were one repeat and one
silent deletion — and a deleted finding can flip a verdict, which is the
failure this branch exists to stop. It was the same mistake corrected in
`council::agree` here (merge on evidence, never on its absence) left
standing in the dedupe itself.

`PostedAnchor` now carries the title and `covers_anchor` requires it to
match. The title rather than the `rule`, on the evidence: the four repeats
of one concern on #86 carried the rules `untrusted-repo-rules`, `Pin
third-party actions to a commit SHA`, and twice nothing at all, while the
title was identical every time. Keying on the rule would leave the
fallback catching nothing in the case it exists for. A comment whose title
cannot be read anchors nothing rather than everything.

Adds the review-flow coverage the helper's unit tests did not give:
`a_finding_whose_anchor_moved_is_not_posted_twice` drives two real reviews
over one defect, the second quoting a different snippet so it hashes to a
fresh fingerprint, and asserts one posted comment. It also asserts the two
identities differ, so it cannot pass by the fingerprint having matched.

The doc comment at the `already_posted` call site still described the
pre-title rule — lane, file and proximity — so it read as though the
fallback could suppress a distinct defect on a nearby line. The code has
required an exact title match since the previous commit; the comment had
not caught up, and tinysweeper's own review believed the comment over the
implementation and filed two findings on it.

Two unplaceable findings with empty or whitespace-only rule ids were incorrectly treated as corroborating, causing one of them to be silently discarded. The fix ensures that an absent rule id is treated as no evidence of a match, so both findings survive independently.

priority high tests confident

Make the severity pin test avoid its own anchor dedupe

The test posts a high finding on the first push, then re-review returns the same title, path, and line with a low severity. already_posted now has an anchor fallback that matches on same lane, file, title, and line proximity, so the downgraded finding is deduplicated before the severity pin is ever observable. With the finding suppressed, second.lanes[0].conclusion becomes success and the assertion fails. Exercise the pin on a finding that the anchor does not suppress, e.g. by keeping the title but changing the file or moving the line outside LINE_TOLERANCE.
