+### Mail-host compiler CPU (x86-64-v3)
+
+The mail host compiles its own Rust and C/C++ source builds for
+`x86-64-v3`. That is the measured guest CPU: avx, avx2, bmi1, bmi2,
+f16c, fma, lzcnt (kernel flag `abm`), movbe, popcnt, sse4.1, sse4.2,
+and ssse3. AVX-512 is absent, so this is not `x86-64-v4`. QEMU iothread
+was not sampled. Do not claim `iothread=1`.
+
+`hosts/mail-vps/configuration.nix` sets `surmount.mailHostCpu.enable`.
+`modules/mail-host-cpu.nix` then sets `gccArch` and `rustTargetCpu` to
+`x86-64-v3`, `NIX_CFLAGS_COMPILE` and `NIX_CXXFLAGS_COMPILE` to
+`-march=x86-64-v3`, and `CARGO_BUILD_RUSTFLAGS` to
+`-C target-cpu=x86-64-v3`. The nixpkgs cc-wrapper applies
+`NIX_CFLAGS_COMPILE` to both C and C++. This nixpkgs does not map
+`gcc.arch` onto rustc, so the Rust flag is set on the derivation.
+
+`nixpkgs.hostPlatform.gcc.arch` stays unset. The cc-wrapper bakes
+`gcc.arch` into the stdenv, and that would rebuild the NixOS closure
+and force the same march onto every package. Generic CI eval
+(`tests/module-eval.nix` without the mail-vps host file) leaves
+`surmount.mailHostCpu.enable` false, so those flags are empty. Flake
+`packages.*` (GitHub Actions `checks.*.ci`, laptop `nix build`) are
+built from `mkPkgsBare` and are not wrapped.
+
+Do not use `-march=native` in this public flake. Stalwart stays a
+release binary (`dontBuild`); this march does not recompile that
+tarball or the RocksDB inside it. Splora and bitcoind or elementsd are
+on the tune list only when a derivation references those attributes.
+The sample host does not enable `surmount.sploraIndexer` and does not
+start bitcoind.
+
+Contract: `t62-mail-host-cpu-v3` in `tests/module-eval.nix`.

 ### Mail-host compiler CPU (x86-64-v3)
 
-The mail host compiles its own Rust and C/C++ source builds for
-`x86-64-v3`. That is the measured guest CPU: avx, avx2, bmi1, bmi2,
-f16c, fma, lzcnt (kernel flag `abm`), movbe, popcnt, sse4.1, sse4.2,
-and ssse3. AVX-512 is absent, so this is not `x86-64-v4`. QEMU iothread
-was not sampled. Do not claim `iothread=1`.
+The mail host compiles C and C++ for `x86-64-v3`, including libraries
+those packages build, not only a named list of top-level derivations.
+That is the measured guest CPU: avx, avx2, bmi1, bmi2, f16c, fma, lzcnt
+(kernel flag `abm`), movbe, popcnt, sse4.1, sse4.2, and ssse3. AES is
+present on that guest. This module does not add a separate `-maes` or
+any flag above `x86-64-v3`. AVX-512 is absent, so this is not
+`x86-64-v4`. QEMU iothread was not sampled. Do not claim `iothread=1`.
 
 `hosts/mail-vps/configuration.nix` sets `surmount.mailHostCpu.enable`.
-`modules/mail-host-cpu.nix` then sets `gccArch` and `rustTargetCpu` to
-`x86-64-v3`, `NIX_CFLAGS_COMPILE` and `NIX_CXXFLAGS_COMPILE` to
-`-march=x86-64-v3`, and `CARGO_BUILD_RUSTFLAGS` to
-`-C target-cpu=x86-64-v3`. The nixpkgs cc-wrapper applies
-`NIX_CFLAGS_COMPILE` to both C and C++. This nixpkgs does not map
-`gcc.arch` onto rustc, so the Rust flag is set on the derivation.
-
-`nixpkgs.hostPlatform.gcc.arch` stays unset. The cc-wrapper bakes
-`gcc.arch` into the stdenv, and that would rebuild the NixOS closure
-and force the same march onto every package. Generic CI eval
-(`tests/module-eval.nix` without the mail-vps host file) leaves
-`surmount.mailHostCpu.enable` false, so those flags are empty. Flake
-`packages.*` (GitHub Actions `checks.*.ci`, laptop `nix build`) are
-built from `mkPkgsBare` and are not wrapped.
-
-Do not use `-march=native` in this public flake. Stalwart stays a
-release binary (`dontBuild`); this march does not recompile that
-tarball or the RocksDB inside it. Splora and bitcoind or elementsd are
-on the tune list only when a derivation references those attributes.
-The sample host does not enable `surmount.sploraIndexer` and does not
-start bitcoind.
+`modules/mail-host-cpu.nix` then sets `nixpkgs.hostPlatform` to this
+host's system with `gcc.arch = "x86-64-v3"`. The nixpkgs cc-wrapper
+reads `targetPlatform.gcc.arch` and writes `-march=x86-64-v3` into
+`cc-cflags-before`. That flag applies to every C and C++ compile that
+uses this host's stdenv, including dependencies such as nixpkgs
+RocksDB, libsodium, and bitcoind or elementsd libraries when those
+derivations are built. The next switch rebuilds that C and C++ closure.
+The module is opt-in. Generic CI eval does not enable it.
+
+The same module still sets `gccArch` and `rustTargetCpu` to
+`x86-64-v3`, and it still prefixes `NIX_CFLAGS_COMPILE`,
+`NIX_CXXFLAGS_COMPILE`, and `CARGO_BUILD_RUSTFLAGS` on a named
+top-level list. The nixpkgs cc-wrapper applies `NIX_CFLAGS_COMPILE` to
+both C and C++. This nixpkgs does not map `gcc.arch` onto rustc, so
+the Rust `-C target-cpu=x86-64-v3` flag stays on those named
+derivations only. The host platform march is what covers C and C++
+dependency builds.
+
+Generic CI eval (`tests/module-eval.nix` without the mail-vps host
+file) leaves `surmount.mailHostCpu.enable` false, so
+`nixpkgs.hostPlatform.gcc.arch` stays unset and the named flags are
+empty. Flake `packages.*` (GitHub Actions `checks.*.ci`, laptop
+`nix build`) are built from `mkPkgsBare` and are not wrapped. Do not
+set this march on those package sets.
+
+Do not use `-march=native` in this public flake. Do not request
+`x86-64-v4` or `-mavx512`. Stalwart stays a release binary
+(`dontBuild`). This march does not recompile that tarball or the
+RocksDB inside it. A nixpkgs RocksDB built as a dependency of something
+this host compiles is in scope. The vendored RocksDB inside the
+Stalwart release tarball is not. Splora and bitcoind or elementsd are
+on the named tune list only when a derivation references those
+attributes. The sample host does not enable `surmount.sploraIndexer`
+and does not start bitcoind.
 
 Contract: `t62-mail-host-cpu-v3` in `tests/module-eval.nix`.

+### Builder login cc, C++, and Lean (2026-11-04)
+
+When `surmount.remoteBuilder.enable` is true,
+`modules/remote-builder.nix` adds `surmount-builder-devtools` to
+`users.users.nixbuilder.packages`. NixOS activation installs that list
+at `/etc/profiles/per-user/nixbuilder/bin`. Measured ssh as nixbuilder,
+including a login shell, already has that directory on PATH. The
+directory was missing because the user had no packages. A later switch
+rebuilds the profile from this list, so the names stay. The public
+module default of `remoteBuilder.enable` stays false. The private
+overlay on horizon sets enable and does not list these packages. The
+module supplies them when enable is true.
+
+This does not set `systemd.services.nix-daemon.path`. It does not
+change the sandbox. Live `/etc/nix/nix.conf` on surmount-1 had
+`sandbox = true`, `sandbox-fallback = false`, and an empty
+`extra-sandbox-paths`. Derivations still use their own stdenv.
+`surmount-remote` and mail-host `gccarch-x86-64-v3` stay on
+`extra-system-features`. `pkgs.gcc` is the host `pkgs` wrapper, so
+mail-host `gcc.arch` still applies to that `cc`.
+
+`cc`, `c++`, `gcc`, `g++`, `clang`, `clang++`, `ld`, `lld`, `ld.lld`,
+and `make` are symlinks. `lean`, `lake`, `leanc`, and `leanmake` are
+wrappers that exec the pinned store paths. `leanmake` uses `dirname`
+of its own path to find `share/lean/lean.mk`, so a symlink in this
+devtools tree would point at the wrong directory. The derivation
+checks that the source paths exist when it is built. On 2026-11-04
+`nix eval --raw .#surmount-lean4.version` printed `4.35.0` and
+`nix eval --raw .#surmount-lean4.outPath` printed
+`/nix/store/v22cg43c1292h1wwbrl32xjl42h84snh-lean4-4.35.0`.
+That store path's `bin/lean --version` printed
+`Lean (version 4.35.0, x86_64-unknown-linux-gnu, commit eb6cafb7290e8bd5f2937522d8d804f58f02bafc, Release)`.
+The devtools profile derivation was not built in that same command.

+   `7dcdd87373d72e7a2173e4db02e20d3d7f495cfd`). cc-wrapper creates
+   `bin/cc` and `bin/c++`. It does not install `ld`. There is no live
+   `gcc --version` because `gcc` was not on PATH.

+3. `ld` from `pkgs.binutils`.

+5. `make` from `pkgs.gnumake` (package expression version 4.4.1). The

+Measured on surmount-1 as nixbuilder before this edit: the login PATH
+did not contain `cc`, `c++`, `gcc`, `g++`, `clang`, `clang++`, `ld`,
+`lld`, `lean`, `lake`, or `leanc`. Those names were also absent from
+`/run/current-system/sw/bin`. An elan tree was on disk at
+`/home/nixbuilder/.elan/toolchains/leanprover--lean4---v4.32.0/bin`
+and was not on PATH. `lean`, `lake`, `leanc`, `clang`, and `ld.lld`
+there failed `--version` with the NixOS stub dynamic linker.
+`leanmake` is a shell script and printed `make: command not found`.
+`leantar` printed `leantar 0.1.19`. This nixpkgs pin has no `leantar`
+attribute, so it is not in the profile. Activation does not delete
+that home tree. The directory name v4.32.0 is not the pin. The pin
+is official tag v4.35.0 in `nix/packages/lean4.nix`. nixpkgs
+`pkgs.lean4` on this lock remains 4.29.1 and is not what the login
+profile installs. The live login PATH does not have 4.35.0 until a
+switch. `just deploy` was not run for this pin.
+
+`~/.nix-profile` pointed at a profile with no `bin`. There was no
+bashrc. A switch would not put the elan bin directory on PATH. It
+replaces `/run/current-system` and the per-user profile from this
+module. Declaring the package is what makes the next switch install
+the tools.
+
+The switch was not run. These names are not on the live nixbuilder
+login PATH until that switch. The flake attribute `.#surmount-lean4`
+evaluates to version 4.35.0, and the built binary at
+`/nix/store/v22cg43c1292h1wwbrl32xjl42h84snh-lean4-4.35.0/bin/lean`

+the fallback when no Rust project does that job. Do not write a new C
+program to stand in for that Python. The C files added under

 | **Stack language** | **NixOS + Nix + Rust**. **No Python** product/ops (fail2ban transitional-at-most). **No NPM**. Gaps filled in-house. [principles.md](principles.md) section 5b. |
 | **No GHC, Haskell, or Python** | Operator 2026-11-06: this repo builds with Rust or C. GHC, Haskell, and Python are forbidden, including transitive dependencies. An eval that reaches them fails. The firewall-tool check was the remaining Haskell edge after nixfmt-rs and is now a non-Haskell `writeShellScriptBin` script. nftables and the firewall stay enabled. Do not construct upstream `nixos-firewall-tool`. Mail-host eval throws on `ghc`, `haskellPackages`, `haskell.compiler`, `hadrian`, ShellCheck, `python`, `python3`, and `pythonPackages`. The mail-host closure walk is `t73-no-haskell-mail-host-closure` in `tests/module-eval.nix`. It rejects shellcheck, ShellCheck, ghc, hadrian, haskell, and a name or pname containing python (python3, pythonPackages, dbus-python, pandas, pip, json-schema-for-humans). An empty walk does not pass. Git keeps `pythonSupport` false. Dual-pin `AGENTS.md`. |
 | **End a broken nested agent** | Operator 2026-11-07: if an L2 or L3 is broken, end it and start a replacement when the work is still owed. Do not spend the turn weighing that choice. Broken includes an early exit with no land report, an L2 that is still reading or editing after it should have spawned an L3, an L2 started with the wrong instructions, and an L3 still on turn 1 with no file save after about 15 minutes. A healthy agent that is already doing the assigned work stays up. Dual-pin `AGENTS.md` section *How agents work here*. |
-| **Existing Rust first, and every dry-run root together** | Operator 2026-11-07: replace a Python step with an existing Rust project. Prefer Rust over C. An existing C project is only the fallback when no Rust project does that job. Do not write a new C program from scratch. The homemade C files this session added under `nix/packages/` are not that replacement. Jinja templates have existing Rust renderers. MiniJinja is one (https://github.com/mitsuhiko/minijinja, accessed: 2026-11-07). Do not reject a Rust renderer because it is not a line-for-line copy of the Python script, and do not write a C renderer in its place. One `just deploy-dry-run` transcript is the full failure list (`--keep-going` is already on the build line). Fix every builder-failed root from that transcript before the next dry-run. Do not fix one root and rerun while other roots from the same transcript remain. Dependents of a failed root are not extra roots. Dual-pin `AGENTS.md` section *Existing Rust or C, and every dry-run root together*. |

 | **No Cloudflare products** | Direct-to-VPS path required. CF Research blog posts may be **cited for learning** only. No orange-cloud, Workers, Tunnel, CF WAF, CF Access as critical path. |
 | **Agents never touch Git's index** | The index is how the operator tracks agent work. No `git add`, `git commit`, `git push`, stage, `git restore --staged`, `git reset`, `git rm --cached`. Do not "clean up" the index. Operator 2026-08-28: stop touching Git. Dual-pin host `~/.grok/AGENTS.md`. |

+## No Python script and no C program inside Nix (operator 2026-11-08)
+
+Operator 2026-11-08, always remember. Do not inline a Python script in a
+Nix file. Do not inline a C program in a Nix file. A build-phase string
+must not carry a Python program body or a C program body. Renaming a
+`.py` file, hiding that text in `printf` or `cat`, or stuffing the same
+text into a patch is the same violation. Handwritten C already forbids
+a C program embedded in Nix. This section adds the Python script, and
+it restates that a shortcut which pastes either language into
+`nix/overlays.nix` is not the fix. Use an existing Rust tool, or change
+the build so the missing program is not invoked. Do not add a package
+whose name contains python.
+
+A Nix file we own must not carry a Meson program body. That includes
+meson.build text, a muon rewrite, a dependency() method sentence, an
+install_headers rewrite, or a PKG_CONFIG_PATH prepend whose purpose is
+to patch a Meson lookup. Hiding that text by rename, printf, cat, or a
+patch is the same forbid. Upstream packages may still be built by their
+own upstream build system. Our Nix files do not contain that program
+text. Operator 2026-11-08 stopped the Meson-in-Nix and C-in-Nix
+patching line.

Broken includes an early exit with no land report, an L2 that is still reading or editing after it should have spawned an L3, an L2 started with the wrong instructions, and an L3 still on turn 1 with no file save after about 15 minutes. A healthy agent that is already doing the assigned work stays up. Dual-pin `AGENTS.md` section *How agents work here*. |
 | **Existing Rust first, and every dry-run root together** | Operator 2026-11-07: replace a Python step with an existing Rust project. Prefer Rust over C. An existing C project is only the fallback when no Rust project does that job. Do not write a new C program from scratch. The homemade C files this session added under `nix/packages/` are not that replacement. Jinja templates have existing Rust renderers. MiniJinja is one (https://github.com/mitsuhiko/minijinja, accessed: 2026-11-07). Do not reject a Rust renderer because it is not a line-for-line copy of the Python script, and do not write a C renderer in its place. One `just deploy-dry-run` transcript is the full failure list (`--keep-going` is already on the build line). Fix every builder-failed root from that transcript before the next dry-run. Do not fix one root and rerun while other roots from the same transcript remain. Dependents of a failed root are not extra roots. Later the same day, handwritten C is forbidden. See the next row.

That includes a `.c` or `.h` file, and C embedded in Nix, bash, a patch, or any other file that emits a C program at build time. The operator cannot audit that code. Removing Python is to shrink the attack surface. Handwritten C is the same class of unauditable code. Upstream projects that are written in C may remain as dependencies. Do not replace removed C with new C. Remove every `.c` and `.h` file we added. Dual-pin `AGENTS.md` section *Handwritten C is forbidden*. |

 | **Agents never touch Git's index** | The index is how the operator tracks agent work. No `git add`, `git commit`, `git push`, stage, `git restore --staged`, `git reset`, `git rm --cached`. Do not "clean up" the index. Operator 2026-08-28: stop touching Git. Dual-pin host `~/.grok/AGENTS.md`. |
 | **Test and deploy procedure** | 2026-10-12: the update, audit, test, and switch command block is [TEST-AND-DEPLOY.md](TEST-AND-DEPLOY.md) section *Update, audit, test, and switch*. `nix flake update`, then `cargo update`, then `just audit-remote`, `just check-remote`, `just check-heavy`, `just deploy-dry-run`, `just btop`, `just deploy`. No `just` recipe for the first two. 2026-10-05: `just publish` is the static-site command. `just deploy` is the host switch. `just deploy-dry-run` is the agent dry-run. `just deploy-host -- ...` stays the explicit equivalent with no default target. 2026-09-20: [TEST-AND-DEPLOY.md](TEST-AND-DEPLOY.md). Agent runs named eval, `just check-remote`, and the dry-run. Operator does not run those to find errors. Operator runs the real switch with Eternal Terminal open. Dual-pin `AGENTS.md` Deploy dry-run is agent work. |
+| **Do not stop before a passing dry-run (operator 2026-11-09)** | Never stop until just deploy-dry-run exits 0. The operator will not run just deploy until that dry-run passes. Stopping to ask the operator to deploy, or ending the task before a green dry-run, wastes the operator's time. The agent runs the dry-run. The agent must not run just deploy. just deploy-host without --dry-run is that same switch. Dual-pin `AGENTS.md` section *Do not stop before a passing dry-run (operator 2026-11-09)*. |
+| **Rebuilds must hit the cache (operator 2026-11-09)** | A later dry-run must not recompile a derivation that a previous dry-run already built, unless an input that derivation depends on actually changed. If the same package builds again with no input change, the cache is broken and that is a bug to fix. Do not treat a full rebuild of an unchanged package as normal. Dual-pin `AGENTS.md` section *Rebuilds must hit the cache (operator 2026-11-09)*. |
+| **Trim dependencies to this host (operator 2026-11-09)** | Drop dependencies the mail host configuration does not need. The machine is surmount-1. Keep what that configuration uses. Do not add a package only because nixpkgs pulls it by default. Dual-pin `AGENTS.md` section *Trim dependencies to this host (operator 2026-11-09)*. |
 | **GitHub tracking and git-flow (operator 2026-09-08)** | Same-turn GitHub issue on plan Approve (plan text, no secrets). Same-turn GitHub issue on operator bug reports, with screenshots attached. Agents never GPG-sign and never push. After the operator signs and pushes the feature branch, the agent opens the PR describing the work. Collaborating git uses git-flow `feature/<slug>` and `bugfix/<slug>` branches, not a pile on `main`. Dual-pin `AGENTS.md` and host `~/.grok/AGENTS.md`. |
 | **Leftovers: complete sentences, none already done** | Operator 2026-08-28: every numbered leftover is a complete sentence. Do not re-list work the screenshot or live host already shows is done. Dual-pin host `~/.grok/AGENTS.md`. |
 | **Prove the operator gate** | Operator 2026-09-02: do not list a step as operator residual without evidence the agent cannot do it (secrets, standing forbid of the real `just deploy` switch, hypervisor, Namecheap hosted DNSSEC Status click). Agents may run one `just check-remote` at a time. The real switch `just deploy` is operator-owned. Agents must not run `just deploy`. `just deploy-host` without `--dry-run` is that same switch and has no default target. Host-local enable is agent work. Using the TUI is the product, not leftover. Operator 2026-09-07: if horizon already has Namecheap env files, `just laptop-renew-cert` is agent work for a DNS-01 issue from horizon. That recipe is not required for the certificate to keep renewing. surmount-1 renews the Let's Encrypt production certificate with HTTP-01. horizon does not have to stay online for that renewal.

+//! Std-only generator for the filesystem-sets capture modes.
+//! Edition 2021. Tables follow the filesystem-sets script output shape.
+//! The header declares fs_type_to_string(statfs_f_type_t) and
+//! fs_in_group(const struct statfs *, enum FilesystemGroups). The script
+//! defines the second parameter as `st` and the group parameter as the
+//! FilesystemGroups typedef. Those forms are the captured C text.
