Group review, feedback, evaluation, observability, and entrypoint code into packages. Keep thin top-level compatibility shims for existing scripts and imports, and mirror the structure in the tests.
Adds the evaluation layer on top of the review traces: five deterministic
scores describing how the reviewer behaved, a bridge that turns human reactions
into ground truth, and a dataset seeded from the reviews already run.
The two are kept apart on purpose. feedback.db has recorded 113 reviews and
zero reactions, resolutions or replies — nobody has ever responded to a bot
comment — so an accuracy metric cannot be built yet. The scorers therefore
measure behaviour, which is computable from data in hand, and feedback_scores
turns verdicts into scores the moment any arrive.
eval_scores.py emits finding_rate, severity_info_ratio, severity_max,
dropped_findings and cost_per_finding into the same ingestion batch as the
trace. Undefined values are omitted rather than reported as zero: an info ratio
over a silent review is undefined, and charting it as 0 would read as perfect
calibration.
dropped_findings needed a parser change. Both parsers silently discard findings
with an unusable path/line, which made a model emitting garbage locations
indistinguishable from one that found nothing. last_parse_dropped() exposes the
delta, read at parse time — after apply_repo_config the drops are the config
working as intended, not the model misbehaving.
feedback_scores.py scores the session ("{repo}#{pr}"), because feedback arrives
days later against a PR and nothing records which re-run produced which
comment. review_acceptance is absent rather than 0 when nothing was engaged.
eval_bootstrap.py registers the score configs, seeds the pragent-reviews
dataset, and can backfill scores onto traces that predate the scorers.
expectedOutput is the reviewer's own prior output, flagged
labelled_by_human: false — a regression baseline, not verified truth.
Also fixes a silent telemetry failure: the ingestion endpoint answers 207 when
only some events succeed, so a batch with every event rejected still looked
like success. Score events were missing the required per-event timestamp and
ingested nothing while reporting 207. _warn_on_rejected_events now logs the
per-event errors under LANGFUSE_DEBUG.
