 - **Remediation / review closure:** Architecture, PERFORMANCE, federation SETUP/MILESTONES, deployment/dev/migrate-tier, and README now use one Markdown-bounded `Held future procedure` form where needed: non-operative/no-current-command-authority; KBN-101-00/-03/-05; external bootstrap → TLS/roles → `mosaic-db-migrator --run` → `mosaic-db-migrator --verify` → Gateway/Compose readiness. Any runner hit outside that section is a -06 semantic failure. Fleet backlog current behavior is PGlite-only. README accurately records the checked-in direct CI migration as an active, isolated-disposable-database, uncertified legacy N-1 DDL exception that is non-authorizing as an operator route and pending -06 removal; it no longer falsely claims the current CI role lacks DDL capability. Independent Codex review found and this pass closed the readiness-endpoint, standalone-verify, CI-factuality, and scanner-boundary findings. Its only residual finding concerns pre-existing tracked `.mosaic/orchestrator` runtime state, which is explicitly excluded and unstaged by task scope; security review found no vulnerability.
 - **Validation:** changed-doc Prettier PASS; `pnpm exec tsc --noEmit -p docs/native-kanban-sot/tsconfig.json` PASS; changed-doc local links 72/0; `git diff --check` PASS; full README/CLAUDE/docs lexical+semantic scan outside reports/scratchpads PASS (106 Markdown documents; 7 operator documents with runner tokens; zero unqualified future-runner/current-CI authority routes); KBN-101 manifest check PASS (10 dependency-ordered cards; -07 docs/-06 fixtures disjoint); docs-only allowlist PASS (16 docs, pre-existing `.mosaic` excluded).
 - **Delivery evidence:** committed `d857463a8a4658e34a77177737860cf82cc26ac6` (`docs(#771): hold unimplemented runner routes`). Pre-push queue guard returned `state=unknown` without failure; the push hook ran repository `pnpm typecheck`, `pnpm lint`, and `pnpm format:check`, all PASS. Push succeeded and `origin/docs/771-kbn101-db-role-split` matched `d857463a8a4658e34a77177737860cf82cc26ac6`. This evidence append is committed and pushed next; `.mosaic/orchestrator/{mission.json,session.lock}` stays pre-existing, unstaged, and excluded. Await exact-head independent re-review/Ultron reverify.

+## 2026-07-15 — rc.16 exact one-finding generic-wrapper remediation intake
+
+- **Objective / scope:** Close only HIGH-1 in `/home/hermes/agent-work/reviews/771-kbn101-contract-rereview10-18e253c.md` against exact head `18e253c8790bdbb5bc30a06c116472213b83b22f`. Documentation/tracking only: no source, Compose, CI, deployment, migration, Vault, report, or `.mosaic` change.
+- **Source-backed correction:** `packages/storage/src/cli.ts` currently labels `storage migrate` a thin wrapper for `pnpm --filter @mosaicstack/db db:migrate` and executes that direct Drizzle command with `execSync`; no `mosaic-db-migrator` executable exists. Therefore the README commented form and user-guide executable form must not describe runner delegation or provide current command authority.
+- **Plan:** Remove the current wrapper command from README/user-guide command guidance; record it as legacy N-1, uncertified, non-operative, and forbidden pending KBN-101-02/-03/-06/-08 activation. Retain only the held future ordered bootstrap → TLS/roles → runner `--run` → `--verify` → readiness sequence and the separately held secure migrate-tier route. Extend KBN-101-06's future semantic fixture/matrix with both exact former forms (including the README commented code-fence form), requiring their failure before inventory/status masking and a source-consistency assertion that direct Drizzle wrapper source cannot be described as runner delegation. Synchronize status/version references only where required, then run document gates, stage docs only, commit, queue-guard, push, and verify the remote SHA.
+- **TDD decision:** not applicable: this bounded task changes documentation only; the required future -06 semantic/source-consistency fixtures are specified as implementation acceptance evidence.
+- **Remediation / validation:** README and user-guide remove the generic wrapper from command guidance and state the direct-Drizzle current-source truth, legacy-N-1/uncertified/non-operative MUST-NOT-INVOKE boundary, named -02/-03/-06/-08 activation cards, future external-bootstrap → TLS/roles → runner `--run` → `--verify` → readiness sequence, and separately held secure migrate-tier route. The KBN-101 rc.16 contract records both exact former forms (README commented code fence and user-guide executable code fence), requires failure before inventory/ownership/status masking, and requires the direct-Drizzle/no-runner-bin source-consistency proof. Prettier passed on all nine changed Markdown documents; changed-doc local links passed (72/0); strict native-kanban contract TypeScript and `git diff --check` passed; full README/CLAUDE/docs scan outside reports/scratchpads passed (106 documents, zero non-normative executable generic-wrapper or false runner-delegation route); and manifest validation passed (10 cards, 90 exact tokens, zero overlaps). Pre-existing `.mosaic/orchestrator/{mission.json,session.lock}` remains excluded.
