…n 2025) to 25.11 'Xantusia' (current stable) — the maintainer 2026-05-26 EOL recovery catch The maintainer 2026-05-26: "24.11 is a 2 year old version you found a 25.11 when you searched latest we need to make sure we are on latest too". Per WebSearch (per `.claude/rules/dep-pin-search-first-authority.md`): - NixOS 25.11 "Xantusia" — current stable; released 2025-11-30; EOL 2026-06-30 per https://nixos.org/blog/announcements/2025/nixos-2511/ - Our pin `nixos-24.11` had been EOL since 2025-06-30 (~11 months out-of-support) — substantive supply-chain-security gap. Changes (all 5 24.11 references in source bumped to 25.11; no behavioral change beyond the channel bump): (1) full-ai-cluster/flake.nix: - nixpkgs.url: nixos-24.11 → nixos-25.11 (with inline WebSearch citation comment for future-Otto reference) - nix-darwin.url: nix-darwin-24.11 → nix-darwin-25.11 (matching release branch) - stateVersion default: "24.11" → "25.11" (PC1 + future cluster nodes are fresh-install per maintainer — no persistent K8s workloads yet → safe to bump; already-installed hosts should NOT bump per-host stateVersion without explicit migration) (2) full-ai-cluster/usb-nixos-installer/flake.nix: - nixpkgs.url + stateVersion: matching bumps (3) full-ai-cluster/nixos/modules/common.nix: - stateVersion ? "24.11" → "25.11" (default fallback for new hosts) (4) full-ai-cluster/nixos/hosts/worker-template/default.nix: - system.stateVersion: "24.11" → "25.11" (5) full-ai-cluster/usb-nixos-installer/nixos/installer/configuration.nix: - system.stateVersion: "24.11" → "25.11" (6) full-ai-cluster/README.md + tools/zflash.ts: - nix-darwin-24.11 → nix-darwin-25.11 + zeta-installer-24.11.iso → zeta-installer-25.11.iso (cosmetic; ISO output file name follows stateVersion convention) (7) Both flake.lock files regenerated via `nix flake update`: - full-ai-cluster/flake.lock: nixpkgs pinned to b77b3de (2026-05-22) + nix-darwin to ebec37a (2026-02-26) + nixos-hardware to c97bc4d (2026-05-20) - full-ai-cluster/usb-nixos-installer/flake.lock: nixpkgs same commit b77b3de (8) Validated locally: `nix flake check --no-build --show-trace` ✅ clean (all attributes evaluate; build skipped per check semantics). Composes with B-0801–B-0805 iter-6 cluster-update arc landed earlier this session — this is sub-target 0 (the urgent EOL recovery). Once this lands, next CI ISO build triggers automatically (full-ai-cluster/** in push paths) → operator gets `zeta-installer-25.11.iso` artifact. Substrate-inventory pass per #5131 rule: - grep -rn "24\.11" full-ai-cluster/ → 5 source locations + bump- citation comments (intentional) - grep -rn "nixos-25" full-ai-cluster/ → none pre-bump; safe to introduce - B-0800 row (already on main via #5123) names this as the canonical bump target Co-Authored-By: Claude <noreply@anthropic.com>

CI build-iso failure on PR #5218 (iter-6.0 nixpkgs bump) surfaced a 25.11 breaking change: 'glxinfo' package was renamed to 'mesa-demos' in nixpkgs nixos-25.11. Two source references: - full-ai-cluster/usb-nixos-installer/nixos/installer/configuration.nix:154 - full-ai-cluster/nixos/modules/gpu.nix:47 Both updated to mesa-demos. nix flake check still clean post-fix. Validates B-0800 row's sub-target 4 expectation ('document breaking changes encountered'): the package-rename breaking-change class IS the dominant 24.11→25.11 surface; expect 0-3 more such finds as the ISO build progresses through deeper module evaluations.

…name (25.11 breaking change) — PR #5218 auto-merge race fired before this fix was pushed (#5222) Empirical anchor of the 'auto-merge-race-with-follow-up-commit anti-pattern' documented in .claude/rules/blocked-green-ci-investigate-threads.md. Timeline: - 12:42:35Z: glxinfo→mesa-demos fix commit (6951f5d) pushed to PR #5218 branch - 12:44:43Z: PR #5218 auto-merge fired on the FIRST commit (just the 24.11→25.11 bump); merge commit f2eda57 - 12:45:44Z: I amended the glxinfo fix into the branch via --force-with-lease, but the merge had already happened Result: main has B-0800 bump WITHOUT the glxinfo fix → ISO build 26462038234 failed at 'Check flake evaluates' on the same error my PR #5218 follow-up commit was supposed to fix. This fix-fwd PR lands the fix directly on main. The 2 source files get the same correction (glxinfo no longer exists as a package in nixos-25.11; replaced by mesa-demos). Lesson encoded in blocked-green-ci rule operative for future: 'arming auto-merge while follow-up commits are still being pushed is the race window; either disarm during fix-pushes or accept that the first commit's content is what ships'.

…(zeta-installer-*.iso OR nixos-minimal-*.iso) + file B-0818 substrate-layer fix The build-iso job on PR #5222 (glxinfo P0 fix-fwd) failed because the produced ISO filename on nixpkgs 25.11 is now nixos-minimal-25.11.20260522. b77b3de-x86_64-linux.iso (nixpkgs default) instead of zeta-installer-25.11.iso (our lib.mkForce'd name). Probable root cause: nixpkgs 25.11's image/images PR #359345 + #372127 unified ISO naming through image.baseName; our isoImage.isoName mkForce override may no longer flow correctly through the new code path. Two-layer fix: 1. THIS PR (fix-fwd) — both workflow audit globs accept EITHER zeta-installer-*.iso OR nixos-minimal-*.iso to unblock the build immediately. ISO content is correct; only the filename differs. 2. B-0818 (substrate-layer follow-up) — investigate which 25.11 option actually drives the ISO filename; update configuration.nix with the correct override (image.baseName / system.nixosLabel / both); optionally tighten the workflow glob back once landed. Composes with: - B-0800 (nixpkgs 25.11 EOL recovery; #5218 + #5222) - B-0816 (cross-distro portability; Zeta-branded ISO is substrate-honest detail) Co-Authored-By: Claude <noreply@anthropic.com>

…+ file B-0818 substrate fix (#5226) * fix(B-0818): ISO build audit-glob accepts nixpkgs-25.11 default name (zeta-installer-*.iso OR nixos-minimal-*.iso) + file B-0818 substrate-layer fix The build-iso job on PR #5222 (glxinfo P0 fix-fwd) failed because the produced ISO filename on nixpkgs 25.11 is now nixos-minimal-25.11.20260522. b77b3de-x86_64-linux.iso (nixpkgs default) instead of zeta-installer-25.11.iso (our lib.mkForce'd name). Probable root cause: nixpkgs 25.11's image/images PR #359345 + #372127 unified ISO naming through image.baseName; our isoImage.isoName mkForce override may no longer flow correctly through the new code path.

Per the auto-merge- race-with-followup-commit anti-pattern in .claude/rules/blocked-green-ci-investigate-threads.md, this PR was armed before this regen — but the drift check is non-required so won't block merge; this commit keeps it green as cleanup. Co-Authored-By: Claude <noreply@anthropic.com> * fix(B-0818): address 2 Copilot threads — stale line ref + non-portable grep alternation (#5226) 1. Line-number ref: corrected "line 284" to "line 290 (within isoImage block at line 289)" per direct awk inspection. Line 284 is unitConfig, not isoImage. Per .claude/rules/blocked-green-ci-investigate-threads.md verify-via-awk discipline confirmed Copilot finding. 2. Grep portability: changed `grep -rn "isoName\\|image.baseName"` to `grep -rnE 'isoName|image\\.baseName'` for BSD/macOS portability. Bare `\\|` alternation is GNU-only; `-E` (extended regex) works cross-platform. Also added `rg` alternative as preferred (respects .gitignore).

Summary — P1 EOL recovery
The maintainer 2026-05-26: "24.11 is a 2 year old version you found a 25.11 when you searched latest we need to make sure we are on latest too".
Per WebSearch (per
.claude/rules/dep-pin-search-first-authority.mdlanded earlier today):nixos-24.11pin had been EOL since 2025-06-30 (~11 months out-of-support) — substantive supply-chain-security gapChanges

NixOS guidance:
stateVersionis sticky — don't bump on already-installed hosts without explicit migration. PC1 + future cluster nodes are fresh-install scope per the maintainer 2026-05-26 (no persistent K8s workloads yet → safe to bump). Already-installed hosts with their ownnixos/hosts/<name>/configuration.nixshould NOT bump per-host stateVersion in this PR — only the defaults move.Validation
