* ralph(eval): baseline + benchmark harness pureintent cpuTime 23.17s, zest cpuTime 14.93s (median of 5). Methodology: NIX_SHOW_STATS cpuTime, eval-cache off, warm fetcher cache. * ralph(eval) cycle 1: disable NixOS options manual on pureintent documentation.nixos.enable = false. Generating the NixOS manual evaluates every option's doc string. nrThunks 20,400,114 -> 19,201,996 (-5.9%), nrFunctionCalls -6.2%, nrPrimOpCalls -7.5%. Package man pages unaffected. Metric pivoted to deterministic NIX_SHOW_STATS counters: cpuTime is unusable on this thermally-throttling machine (same eval = 11s..21s). * ralph(eval): switch home target zest -> sincereintent (per request) sincereintent home config baseline: nrThunks 5,323,428 / calls 3,227,404 / primops 1,565,120 (deterministic). * ralph(eval) cycle 2: disable home-manager options manpage manual.manpages.enable = false in shared modules/home/default.nix. HM builds home-configuration.nix(5) by default, evaluating every HM option's doc string. sincereintent nrThunks 5,323,428 -> 3,551,679 (-33.3%), calls -35%, primops -39%. * ralph(eval): record cycle-2 pureintent gain (shared HM module) pureintent nrThunks 19,201,996 -> 17,431,437 (-9.2%); cycle-2's manual.manpages.enable=false also feeds pureintent's embedded home-manager via modules/nixos/default.nix. Total pureintent -14.6% from baseline. * ralph(eval) cycle 3: profiling + dead-ends (no behaviour-preserving win) Confirmed: nixpkgs single-instantiation (no 2x trap), unused inputs are lazy (no counter impact), escapeShellArg hotspot is HM file-linking + /etc (not patchable here). Remaining eval cost is feature-bound (embedded HM, vira/kolu, google-cloud-sdk/pandoc/omnix). * ralph(eval) cycle 4: drop heavy home.packages (yt-dlp/lima/omnix/pandoc/gcloud) User-approved behaviour change. Removed from shared modules/home/cli/terminal.nix (kept hledger). pureintent nrThunks 17,431,437 -> 16,989,720 (-2.5%), sincereintent 3,551,679 -> 2,757,201 (-22.4%). Totals from baseline: pureintent -16.7%, sincereintent -48.2%. * ralph(eval): finalize report (final measurement, key findings, cost breakdown)
