**P-H032 — Config-driven SQL table names (parent plan `plan-2026-05-16-prelaunch-audit`, sub-plan `plan-stage-c-high-batch`)**.

P-H032 — Config-driven SQL table names (parent plan plan-2026-05-16-prelaunch-audit, sub-plan plan-stage-c-high-batch). 207 SQL string substitutions across 21 source files migrated from hardcoded 'massu_<table>' literals to ${t('<table>')} template-literal substitutions resolving through a new lib/sql-table-names.ts single-source-of-truth helper. Closes the split-brain bug class where tool names were already config-driven via getConfig().toolPrefix but persistence wasn't — non-default-prefix customers (e.g. toolPrefix: 'foo') would have tools named foo_ but still write to / read from massu_ tables, missing their own data. Default-prefix customers (100% of current installs) see ZERO behavior change.

Added

• packages/core/src/lib/sql-table-names.ts — typed MassuTableSuffix union (20 canonical suffixes) + t(suffix) helper returning \${getConfig().toolPrefix}_${suffix}\``. The typed union catches typos at compile time; the helper makes the prefix resolution single-source.
• packages/core/src/tests/sql-table-names-no-hardcoded.test.ts — 2-case drift-guard: (1) walks packages/core/src/** and asserts zero bare massu_<canonical-suffix> literals outside the SoT module + tool-name registries + tests; (2) verifies t() resolves with the configured prefix. Closes the regression class where a future SQL string is written with a hardcoded literal and silently breaks custom-prefix installs.

Fixed

• 20 source files migrated (207 total substitutions): db.ts (64), sentinel-db.ts (46), python-tools.ts (30), tools.ts (13), page-deps.ts (8), python/impact-analyzer.ts (6), middleware-tree.ts (5), python/migration-indexer.ts (4), python/model-indexer.ts (4), validate-features-runner.ts (4), trpc-index.ts (4), python/coupling-detector.ts (3), python/domain-enforcer.ts (3), python/route-indexer.ts (3), import-resolver.ts (2), knowledge-tools.ts (2), python/import-resolver.ts (2), sentinel-scanner.ts (2), domains.ts (1), sentinel-tools.ts (1), plus the hooks/pre-delete-check.ts Python-index queries (4) for parity with the runtime modules.

Verification

• packages/core tsc --noEmit: exit 0
• packages/core vitest run: 2269/2269 PASS (Node 22) — 2 new test cases above the 1.10.6 baseline
• packages/core npm run build:hooks: exit 0 (esbuild bundles lib/sql-table-names.ts into each affected hook)
• Default-prefix behavior unchanged: t('imports') returns 'massu_imports' exactly as the prior hardcoded literal.
