fix(openai): bump client timeout

fix(planner): increase OpenAI timeout & add graceful timeout handling

fix(planner): increase OpenAI timeout & add graceful timeout handling

feat(pipeline): attach executor result to FinalResult and expose real query output to API/UI

feat(pipeline): enable SQL-only repair + log-only repair for early stages with full traces/metrics

feat(pipeline): enable SQL-only repair + log-only repair for early stages with full traces/metrics

feat(metrics): initialize all counters with zero and extend Prometheus rules for full Grafana coverage

feat(metrics): enable repair tracking and Prometheus lifecycle for observability

fix: resolve SQLite path mismatch and ambiguity false positives

feat(metrics): add repair_attempts_total and wire into repair loop outcomes

fix(verifier): correct result flag consistency for verified outputs

fix(core): non-zero generator timing + one-shot EMPTY retry; post-verify drop LIMIT to recover EM when ExecAcc=1

perf(planner): trim relevant tables (+cache) to cut latency; keep repair loop & rich traces

refactor(core): trace schema upgrade, verifier/executor sync, benchmark plot polish

feat(trace): enrich StageTrace (sql_length/row_count/verified/error_type/repair_attempts/skipped) and propagate in normalization; tag EmptySQL; annotate repair attempts

feat(core): refine pipeline & verifier; improve Spider benchmark accuracy

feat(core): always emit per-stage traces in Pipeline.run (fallback when StageResult.trace is empty)

chore(factory): safely load .env via dotenv (with fallback under CI)

feat(metrics): instrument per-stage and pipeline_total latency; count pipeline_runs_total (ok/error/ambiguous)

feat(metrics): integrate Prometheus; expose /metrics; instrument safety & verifier

refactor(core): DI-ready Pipeline; add registry + YAML factory + typed trace/result

fix(verifier): robust aggregate detection and projection-level semantic check

feat(trace): standardize StageTrace (add summary) and coerce duration_ms to int at API boundary

refactor(core): DI-ready Pipeline; add registry + YAML factory + typed trace/result

refactor(core): DI-ready Pipeline; add registry + YAML factory + typed trace/result

test-mode: stub runner in router; factory stubs accept positional calls

fix(router): lazy pipeline build for pytest; fix(factory): stubs accept positional/keyword args

refactor(core): DI-ready Pipeline; add registry + YAML factory + typed trace/result

refactor(core): DI-ready Pipeline; add registry + YAML factory + typed trace/result

refactor(core): DI-ready Pipeline; add registry + YAML factory + typed trace/result

refactor(core): DI-ready Pipeline; add registry + YAML factory + typed trace/result

fix(pipeline): allow optional schema_preview in run() for better typing compatibility with benchmarks

feat(safety): harden SQL validation (multi-CTE, recursive WITH, unicode normalization, precise errors, EXPLAIN gate)

tests green: fix pipeline reference in router and adjust verifier logic for aggregation & error handling

fix(pipeline): align backend-frontend schema and stabilize SQL flow

build(mypy): fix type errors and add safety guards for None values
