* docs: Ralph report scaffolding + pureintent eval baseline (10.87s)
* cycle-1: drop nixvim — pureintent eval 10.87s → 6.98s (-36%)
nixvim's home-manager module system is by far the dominant cost of
evaluating `nixosConfigurations.pureintent`: a profile of selective
imports puts it at 3.97s of the 10.87s baseline (~36%).
Replace it with a minimal `programs.neovim.enable = true` configuration.
The runtime behaviour of `nvim` changes (no plugins, no LSP, no
mapleader/telescope/treesitter/etc.) — accepted by the user.
Measured on srid-nc (nixos, 6.12.85 kernel), 7 warm-cache runs with
`--option eval-cache false`:
baseline: 10.85 10.86 10.86 10.87 10.87 10.88 10.91 -> median 10.87s
cycle-1: 6.94 6.96 6.98 6.98 7.02 7.02 7.73 -> median 6.98s
Other configurations still evaluate:
- nixosConfigurations.naiveintent
- darwinConfigurations.infinitude-macos
- homeConfigurations."srid@zest"
Removes flake input `nixvim` (+ its `flake-parts`, `nixpkgs`, `systems`
sub-inputs from the lock).
* docs: wrap up Ralph report (10.87s -> 6.99s = -35.7%)
7 dead-ends documented so they don't have to be re-tried. Key
finding: after dropping nixvim (cycle 1), the eval floor is
home-manager's per-entry submodule materialisation
(systemd.user.services / programs.ssh.matchBlocks), not the
option-declaration count of any wrapper module. Inlining
jumphost-nix or vira moves the cost; it does not eliminate it.
- Move AI config from nix-agent-wire/srid to ./AI
- Update flake input: srid/AI -> srid/nix-agent-wire
- Update home modules to use local AI folder via flake.self.outPath
Systemd user services don't inherit shell environment. Add PATH with
essential tools (git, coreutils, gnugrep, gnused, findutils) so opencode
can run basic commands.
