# Documentation completion checklist — #1050 C1 fix round

## Required artifacts

- [x] `docs/PRD.md` exists; #1050 C1 requirement 13 binds the complete in-scope remote stack source chain, and requirement 15 binds pipeline-level exact case+arm execution coverage, executable aggregation, production-bound archive purity, and canonical Alpine/BusyBox plus Debian portability.
- [x] User guide: not applicable; no user-facing production installer behavior changed.
- [x] Admin guide: not applicable; no operator procedure or deployment behavior changed.
- [x] Developer guide: existing `docs/guides/installer-state-machine.md` defines the fail-closed installer model; the C1-specific remote-arm contract and evidence live in the PRD, scratchpad, and scoped verification report.
- [x] OpenAPI and endpoint index: not applicable; no API changed.
- [x] Sitemap: not applicable; no navigation changed.

## API and structural coverage

- [x] API schema/auth/error coverage: not applicable; no endpoint changed.
- [x] Guide book indexes: not applicable; no guide page was added or moved.
- [x] Root hygiene preserved; all new artifacts are under `docs/reports/verification/1050-c1-fix-round/` and the active scratchpad remains under `docs/scratchpads/`.

## Review and publishing

- [x] Verification documentation is in the same logical change set as the shell-test remediation.
- [x] Trust boundary states both halves: the digest proves fetched bytes remain identical through execution/verify-after; it does not authenticate authorship against provider/TLS compromise. Independent provenance is the inherited PRD v2 §3 deferral.
- [x] Round-3 Codex code review APPROVE (confidence 0.92, zero findings) and security re-review risk NONE (confidence 0.96, zero findings). The initial HIGH trust-root finding remains documented as the canonical signed-provenance deferral, not hidden.
- [x] Round-4 review cycle closed: two blocking Codex findings (missing dependency ordering; production manifest comments misparsed) were accepted and fixed. Final code review APPROVE (confidence 0.94, zero findings) and security risk NONE (confidence 0.96, zero findings).
- [x] Round-5 exact arm coverage and archive-purity controls reviewed: Codex code APPROVE (confidence 0.93, zero findings) and security risk NONE (confidence 0.96, zero findings).
- [x] Round-6 executable aggregation and production archive-selector binding reviewed: Codex code APPROVE (confidence 0.94, zero findings) and security risk NONE (confidence 0.97, zero findings).
- [x] Round-7 BusyBox-safe marker inventory and dual-runtime evidence reviewed: Codex code APPROVE (confidence 0.96, zero findings) and security risk NONE (confidence 0.97, zero findings).
- [x] Canonical evidence remains in-repo. No external publishing action was requested or performed.
