From 2d746ac4917ace88d9ed4268da9baf118cbbde0c Mon Sep 17 00:00:00 2001 From: James Wiesebron Date: Thu, 9 Jul 2026 12:47:33 -0700 Subject: [PATCH 1/8] [jwbron/live-eval-corpus] review: live-enabled corpus format and ten live cases Phase 1 of the live A/B eval plan (Khan/actions#232). The corpus gains an opt-in live block carrying what a real model run needs and the deterministic replay does not: - prContext (PR title/description/author/base; the description is untrusted author text, so an adversarial case can carry its payload there or in the diff), - a post-change file tree on disk next to the case, via a new /case.json + /tree/ layout that coexists with flat .json (a directory containing case.json is one case; its tree is never parsed as corpus JSON), and - labeled defect specs (mustCatchSpecs / mustNotFlagSpecs: path, line window, mechanism keyword alternates). Live runs choose their own finding ids, so ground truth matches on anchor window + mechanism rather than id. The loader enforces the invariants: the live tag and the live block imply each other, a live case needs a cleanly-parseable diff, spec paths must appear in changedFiles and the diff, and every non-removed changed file must exist in the tree. loadLiveCorpus() returns the subset. The live half lives in corpus/live.ts; loader.ts re-exports it as the single public surface. Ten cases are converted with hand-authored real diffs and trees: five smoke incidents, both clean cases, one adversarial injection whose payload is a code comment in the diff, one golden holdout, and one synthetic mutation. Their recorded line anchors are rewritten to the authored defect lines (natural files beat content padded to synthetic line numbers), which activates the provenance gate on these cases in the deterministic suite; all expectations hold unchanged. --- .changeset/review-live-corpus-format.md | 5 + .../corpus/clean/clean-typed-refactor.json | 15 - .../clean/clean-typed-refactor/case.json | 33

The re-run's skill auditor investigated the mechanism and declined it as unquotable, and no correctness lens surfaced it; the case pins that a skill-adjacent correctness issue must surface regardless of which lens owns it. - trial-erasure-suite-flag-mock: the erasure test suite pins the rollout flag on in its shared test-env constructor, so the flag-off path (where the unchanged EraseUser silently skips the compliance deletion) is never exercised. Anchors and spec windows were mechanically asserted against added diff lines at generation time, as with the existing trial cases. --- .../trial-dedup-composite-key/case.json | 83 ++++++++++++++ .../tree/services/notes/save.go | 49 ++++++++ .../tree/services/notes/save_test.go | 97 ++++++++++++++++ .../tree/services/notes/store.go | 44 ++++++++ .../case.json | 79 +++++++++++++ .../tree/services/notes/save.go | 49 ++++++++ .../tree/services/notes/store.go | 41 +++++++ .../trial-erasure-suite-flag-mock/case.json | 78 +++++++++++++ .../tree/services/notes/erasure.go | 56 ++++++++++ .../tree/services/notes/erasure_test.go | 105 ++++++++++++++++++ .../tree/services/notes/store.go | 51 +++++++++ 11 files changed, 732 insertions(+) create mode 100644 workflows/review/eval/corpus/incidents/trial-dedup-composite-key/case.json create mode 100644 workflows/review/eval/corpus/incidents/trial-dedup-composite-key/tree/services/notes/save.go create mode 100644 workflows/review/eval/corpus/incidents/trial-dedup-composite-key/tree/services/notes/save_test.go create mode 100644 workflows/review/eval/corpus/incidents/trial-dedup-composite-key/tree/services/notes/store.go create mode 100644 workflows/review/eval/corpus/incidents/trial-dedup-eventual-consistency/case.json create mode 100644 workflows/review/eval/corpus/incidents/trial-dedup-eventual-consistency/tree/services/notes/save.go create mode 100644 workflows/review/eval/corpus/incidents/trial-dedup-eventual-consistency/tree/services/notes/store.go create mode 100644 workflows/review/eval/corpus/incidents/trial-erasure-suite-flag-mock/case.json create mode 100644 workflows/review/eval/corpus/incidents/trial-erasure-suite-flag-mock/tree/services/notes/erasure.go create mode 100644 workflows/review/eval/corpus/incidents/trial-erasure-suite-flag-mock/tree/services/notes/erasure_test.go create mode 100644 workflows/review/eval/corpus/incidents/trial-erasure-suite-flag-mock/tree/services/notes/store.go diff --git a/workflows/review/eval/corpus/incidents/trial-dedup-composite-key/case.json b/workflows/review/eval/corpus/incidents/trial-dedup-composite-key/case.json new file mode 100644 index 00000000..6d967426 --- /dev/null +++ b/workflows/review/eval/corpus/incidents/trial-dedup-composite-key/case.json @@ -0,0 +1,83 @@ +{ + "id": "trial-dedup-composite-key", + "tags": [ + "incident", + "trial", + "live" + ], + "category": "incident-repro", + "description": "Sanitized structural rewrite of a v1.4.0 re-run miss (dedup push): the new save path keys its duplicate check on Note.Body alone while the Note entity carries a Kind that readers select on (the store docs say notes of different kinds may share a Body), so a same-Body note of a different kind is silently never saved.

Cost is about one dollar per A/B run for the pair (two cases, two arms). The other trial cases stay out of smoke deliberately to hold the per-push price down; the full-eval label still covers them. --- .../eval/corpus/incidents/trial-dedup-composite-key/case.json | 3 ++- .../corpus/incidents/trial-erasure-suite-flag-mock/case.json | 3 ++- 2 files changed, 4 insertions(+), 2 deletions(-) diff --git a/workflows/review/eval/corpus/incidents/trial-dedup-composite-key/case.json b/workflows/review/eval/corpus/incidents/trial-dedup-composite-key/case.json index 6d967426..e8452eae 100644 --- a/workflows/review/eval/corpus/incidents/trial-dedup-composite-key/case.json +++ b/workflows/review/eval/corpus/incidents/trial-dedup-composite-key/case.json @@ -3,7 +3,8 @@ "tags": [ "incident", "trial", - "live" + "live", + "smoke" ], "category": "incident-repro", "description": "Sanitized structural rewrite of a v1.4.0 re-run miss (dedup push): the new save path keys its duplicate check on Note.Body alone while the Note entity carries a Kind that readers select on (the store docs say notes of different kinds may share a Body), so a same-Body note of a different kind is silently never saved.
