-- **v1.25 (2026-06-20):** **§3.3 renamed** — Priority 3 "Hardened Security" → "Secure / Security By Design", aligning the priority name with the Security By Design principle (security built in from the start rather than bolted on).
+- **v1.25 (2026-06-20):** **§3.3 renamed** — Priority 3 "Hardened Security" → "Security by Design", aligning the priority name with the Security By Design principle (security built in from the start rather than bolted on).
 - **v1.24 (2026-06-19):** **§8 Documentation (Texinfo) added** — Texinfo codified as the first-class technical-manual format for user-facing Spacecraft Software projects, following GNU conventions (`@dircategory`/`@direntry` for Info-directory registration; `@copying`/`@titlepage`/`@node Top`/`@menu` required structural elements; `make info`/`make html`/`make pdf` Makefile targets via `makeinfo`/`texi2any`/`texi2pdf`; `.info`/`.html`/`.pdf` outputs; CC-BY-SA-4.0 default with GFDL-1.3-or-later as a permitted alternative; `install-info` packaging integration for Guix/Nix/PKGBUILD). Prior §8–§15 renumbered §9–§16 accordingly; §16 compliance checklist gains a §8 bullet; Skill Cross-References gains a Texinfo-manual row.
 - **v1.23 (2026-06-19):** **§14.1:** registered the **Docs** subdomain (`Docs.SpacecraftSoftware.org`), paired in the same change-set with its row and GitHub-repo link in Spacecraft-Software/Projects `PROJECTS.md`. The `Docs` repo — a centralized aggregation of the umbrella's planning corpus (PRDs, plans, TODOs, research) organized by project then document type — was created private with §5.2 posture files and §4.3 REUSE compliance (CC-BY-SA-4.0 documents, `reuse lint`-clean). (Subdomain table is §15.1 after the v1.24 renumber.)
 - **v1.22 (2026-06-18):** **§7 Shell Environment added** — codifies Nushell, Ion, Brush, and Bash as four equally first-class shell environments; §7.1 Script Portability Policy mandates POSIX-compatible scripts by default, Nushell/Ion native variants where shell-native idioms are required, and prohibits Bashisms in shared scripts. Prior §7–§14 renumbered §8–§15 accordingly. §15 compliance checklist gains a §7 bullet; Skill Cross-References gains a shell-work row (`spacecraft-cli-shell` + `spacecraft-cli-preference`). **§14.2:** added email-obfuscation note — the `Mohamed.Hammad [at] SpacecraftSoftware.org` form is permitted in plain-text prose, but PKGBUILD `# Maintainer:` lines and `SPDX-FileCopyrightText` headers must retain the full address (parsed by `makepkg`/`pkgcheck` and `reuse lint`).
