* feat(planguard): read sqlc statement text and load a strict plan corpus * fix(planguard): fail on unextracted statements, keep fragments mode-neutral * feat(planguard): plan assertions, scoped sort exemptions and narrow retired-index verdicts * fix(planguard): an errored run always fails * fix(planguard): keep subplan conds off their parent scan; fail on unanalyzed budgets * feat(planguard): read-only plan runner, reports and the run command * fix(planguard): validate identifiers in emitted scripts; prove read-only runs * feat(planguard): end-state corpus, planted regressions and the generated cached-plan policy * fix(planguard): derive observer cases from data; mark legacy generic plans * fix(planguard): bound the dense-region route resolvers; test policy refusals * fix(planguard): re-measure the dense-region route cases; cover every policy refusal * feat(planguard): synthetic fixture built through the migrations, checked in CI * ci(planguard): build the fixture once; guard fixture data for identifiers * fix(planguard): hash every fixture generator input; harden the fixture guard * feat(planguard): snapshot diff over every column, named result classes and cursor walks * fix(planguard): bound the relaxed diff classes; derive the cursor tie from data * fix(planguard): refuse multi-statement text in the corpus runner * feat: read-only server mode and an HTTP page diff between two builds * fix(planguard): refuse escape strings and psql meta-commands in corpus text * fix: storediff follows each build's own cursor; prove read-only gates via the log * fix(planguard): match the PostgreSQL lexer on high-bit bytes; check every emitted line * feat(admin): daily read-only plan check on the maintenance pool, its metric and report * feat(planguard): daily prod check behind planguard.daily_check * fix(planguard): cancel fresh runs at shutdown; expose a never-ran check * ci(planguard): pin the fixture server and collation; refresh baselines * fix(planguard): calibrate route budgets on one dataset; skip entries whose index is absent
