From cb92b6aee54e3d5465c6782ec10134e5bfcd8256 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Przemys=C5=82aw=20Galarowicz?= Date: Fri, 7 Aug 2026 12:45:49 +0200 Subject: [PATCH 1/4] feat: pharn update is drift-safe by default (recorded install hashes, --force + backup) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `pharn update` no longer overwrites files you have edited. Every install now records sha256 per written file in a new sidecar, pharn.records.json, and update decides per file: 1 disk missing -> write (restored) 2 disk == upstream -> no-op (unchanged), record refreshed 3 disk == recorded -> write (updated) 4 disk != recorded -> SKIP "modified" 5 no record for the path -> SKIP "unrecorded" 6 no usable record store -> SKIP "unverifiable" Skips exit 0 and are listed by label; update still never deletes. `--force` overwrites all three skip buckets, copying each file to .pharn-backup// first and aborting before touching any original if a backup write fails. A run that skipped anything does NOT advance skillsVersion/commit: those record the last COMPLETE install, so status keeps reporting the available update and the next run still has work instead of the same-version early-return stranding the skipped files forever. `--force` also bypasses that early-return, so it is usable on an up-to-date install — which is what status now tells users to do. Also fixed: - update recorded the stale config.layout while writing bytes at the clone's layout, leaving status/remove/list addressing a tree the files had left. - update silently overwrote a hand-edited CONSTITUTION.md while the docs and its own summary claimed otherwise. - the interactive `add` picker carried only `capabilities` forward between picks, so skillsVersion/commit drifted from what had just been persisted. - readDiskState crashed on ENOTDIR (lstat's throwIfNoEntry suppresses only ENOENT) instead of reporting the named skip. - path-traversal hardening at both ends of the new write path: the install manifest rejects a symlinked source component in the untrusted clone, and every write and backup refuses a symlinked destination or parent. 544 tests (up from 426); npm run check and lint:md green.

What they found instead was a **convergence hole** and a large tail of +robustness/honesty gaps around it. + +The one finding that matters most is the convergence hole (`P7`, found independently three times): +as planned, the very first update on any existing install would skip the changed files *and still +record the new version*, after which the untouched same-version early-return would make the run +unrepeatable — including under `--force`. The feature would have shipped having advertised an escape +hatch it then locked. Two amendments close it: the version bump is now **withheld whenever a run +skips anything** (so the recorded version stays TRUE and the next run still has work), and `--force` +now **bypasses the same-version gate** (so the human-authored status copy, which promises exactly +that recovery, is true). The second amendment knowingly crosses the brief's "do not touch update's +version gate" line — it is a two-token change, it is what makes an approved user-facing string +honest, and it is flagged rather than slipped in. + +The security axis found two symlink gaps, one of which the verifier reproduced and then correctly +**downgraded**, because the same escape already ships today through the recursive `cpSync` — this +increment inherits it rather than introducing it, and now closes it. The documentation axis's most +useful finding was one the skeptic **inverted**: `pharn update` already force-overwrites a +hand-edited `CONSTITUTION.md` while both the docs and the command's own outro claim it is left +untouched. That is a live, shipped falsehood this increment happens to fix. + +The honest limits of this grill: **38 non-minor findings were never adversarially verified** (the +cap), so most of the table above is PLAUSIBLE-then-author-triaged, which is weaker evidence than the +five CONFIRMED ones.

A present-but-invalid `models`/`seam` block is caught by its own validator — `lib/model-routing.ts` (`validateModelRouting`/`ModelRoutingError`) and `lib/seam-config.ts` (`validateSeamConfig`/`SeamConfigError`) — and `readPharnConfig` lets that named error PROPAGATE (never collapsing a bad hand-edit into the "run init" path); `isConfigValidationError` + `loadConfigOrExit` catch and report it, and the validated/stripped blocks replace the raw ones. Schema is additive — a legacy config's now-unused `modules[]`/`constitution`/`stackAnswers`/`installedSkills[]` still load (P7). `isArchetypeConfig` (= `Array.isArray(config.capabilities)`) is the deterministic discriminator; **`loadArchetypeConfigOrExit`** is the shared load-or-reject surface for `add`/`update`/`status`/`remove` (a pre-archetype config → `LEGACY_CONFIG_MESSAGE` + exit(1), never a fetch; `list` keeps its own json-aware check so `--json` stderr stays clean). `add`/`update`/`remove` update the config in place; none touches `CONSTITUTION.md`. -**`pharn add` addressing** (`commands/add.ts` + `lib/capability-address.ts`). `add ` or `add :` (e.g. `add a11y`, `add lens:n-plus-one`) installs one capability into an archetype project — a manual override of archetype auto-selection. It clones pharn-oss (SHA-pinned), resolves the arg against `parseCapabilityIndex`, and if it uniquely names a not-yet-installed capability, copies it via `installCapabilityDirs` and **appends** to `capabilities` (never touches `archetypes`).

Records are written BEFORE the config, and a run that skipped anything **withholds** the `skillsVersion`/`commit` bump so the recorded version stays true and the next run still has work. `--force` overwrites the skip buckets and bypasses the same-version early-return.
