docs(agent): close NEXT #64–#73 after parallel land

Landed worktree batch: migration docs, installer chown, theme-state
reader, theme fidelity, audit/import tools, IR docs, template-sot check,
hardware MOTD tips. Verified contrast + template-sot + flake check.

 ## NEXT
 
-### 64. MIGRATION.md snapshot layout vs installer
-Installer creates disko `@snapshots` → `/.snapshots` and a first-boot
-oneshot for nested `/home/.snapshots`. MIGRATION still speaks of
-top-level `@home-snapshots` (TuringMachine vocabulary). One paragraph
-clarifying installer layout vs migration machines. Cost: docs only; V0.
-
-### 65. Installer soft gap: chown flake dir
-`chown -R 1000:100` on the generated flake assumes first-user UID/GID.
-Use the real install username’s uid/gid (or `id` after user create).
-Cost: small; V0–V1.
-
-### 66. Fail-closed / friendlier theme-state errors in `mkFlake`
-Missing or invalid `theme-state.json` should fail early with a pointer
-to schema/docs, not a raw `readFile`/`fromJSON` stack. Related:
-`settings.displayProfile*` defaults; unknown border role. Cost: medium
-lib UX; V0–V1.
-
-### 67. Theme fidelity / hierarchy nits (popular ports)
-gruvbox Material vs classic name+btop split; nord inverted subtext/text;
-tokyo-night btop warm fg; ethereal surface=base; retro-82 surface
-darker than base; ristretto subtext=text + btop bg drift; flexoki-light
-bright-black. Cost: small JSON/btop each; V0 contrast + V1.
-
-### 68. #52 residual ANSI
-**vantablack** `ansi[8]` still `#fdfdfd` (diverges from `muted #666666`);
-**osaka-jade** `ansi[3]` still warn-green `#459451` while `warn` is
-`#E5C736`. Treat as fidelity bugs (align with muted/warn). Cost: tiny
-JSON; V0 contrast.
-
-### 69. audit-theme-design identity exemptions
-Document expected CVD/hue noise for white/vantablack/lumon/hackerman/
-matte-black/miasma so audits don’t “fix” identity into traffic lights.
-Optional special-case in the report script. Cost: docs or small script; V0.
-
-### 70. Import pipeline hierarchy when ANSI 0==8
-`tools/import-palettes.py` maps surface←color0, overlay←color8; when
-0==8 (gruvbox, everforest) surface=overlay; light themes get sludge
-mantle. Allow role overrides independent of ANSI; don’t re-import
-without a hierarchy pass. Cost: tool + convention; V0.
-
-### 71. Portal/Flatpak IR camera — document (a)
-Ship the recommended path only: document that the WirePlumber *v4l2*
-IR-hide does not cover libcamera/Flatpak pickers (ROADMAP § Webcam).
-Leave (b)/(c) engineering for a T14s session. Cost: docs; V0.
-
-### 72. Installer ↔ template SoT — CI parity check
-Optional pure check that the install share ships the same template
-files as `templates/downstream`. Cost: small tool + flake check; V0.
-
-### 73. Post-install hardware hints residual
-#43 shipped Firmware MOTD/tip. Still open: fingerprint + doctor
-one-liners (once or until dismissed). Cost: small greeter/MOTD/notify;
-V1–V2.
-
 ### 74. Unattended-install test matrix
 `test-install.sh` always LUKS+swap; add (or document) no-swap and
 explicit no-LUKS paths via env flags only. Cost: script + KVM time; V2.
