feat(metric): Merge Strategy detection + mergeCommit ingestion (#75, #76)#77
Merged
Conversation
) Ingest (#75): capture mergeCommitSha + commit subjects - PullRequest gains merge_commit_sha / merge_commit_parent_count; CommitRef gains subject (messageHeadline). All backward-compatible. - github_reader: mergeCommit added to gh field lists; the light GraphQL pass now also fetches mergeCommit{oid parents{totalCount}} + per-commit messageHeadline (renamed _fetch_pr_enrichment_graphql). Metric (#76): Merge Strategy detection per repo + reliability flag - New analysis/merge_strategy_detector.py: per-PR classify (2-parent ground truth -> commit_refs presence in main -> squash (#N) subject stamp), aggregated to merge|squash|rebase|mixed|unknown with dominant_share and commit_metrics_reliable (False only for squash/mixed). Strictly per-repo. - Wired full chain: schema, aggregator (logs unknown reason), report writer Merge Strategy section, narrative finding, i18n (en + pt-br), TS types, platform UI (repo-detail reliability badge + compare column desktop/mobile), ingest route + migration 019 (indexed columns), docs/METRICS.md. Tests: tests/test_merge_strategy_detector.py (10 cases) + 8 added to tests/test_github_reader_state.py. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Implements #75 (ingestion enabler) and #76 (the metric that consumes it).

Backward-compatible defaults.github_reader:mergeCommitadded to the gh--jsonfield lists (cheap{oid}on every path); the light GraphQL enrichment pass now also fetchesmergeCommit{oid parents{totalCount}}and per-commitmessageHeadline(renamed_fetch_pr_enrichment_graphql). Parent count lands on the GraphQL path; gh-only paths get the sha and fall through to the heuristic.#76 — Merge Strategy detection per repo + reliability flag

The compare-table column needs migration
019_merge_strategy.sqlapplied to Supabase before those columns populate. The repo-detail badge reads the JSONB payload and works regardless.Closes #75
Closes #76
