+## Pre-commit hooks (web/)
+
+The repo uses **husky** git hooks (installed via `web/`'s **lint-staged** + npm) to catch
+lint/format/type/API-drift errors locally, before they reach CI. Because the git root and
+the npm project dir differ (monorepo: no root `package.json`, the JS/TS project lives
+entirely in `web/`), the wiring is:
+
+- `husky` + `lint-staged` are devDependencies of `web/package.json` (not a root package —
+  there isn't one).
+- The committed hook scripts live at the repo root: `.husky/pre-commit`, `.husky/pre-push`,
+  `.husky/commit-msg`.
+- `web/package.json`'s `prepare` script (`cd .. && husky`) runs on `npm install` inside
+  `web/` and points git at the repo-root `.husky` dir (`git config core.hooksPath
+  .husky/_` — the `_` subdir is husky's generated internal dir, gitignored via its own
+  `.husky/_/.gitignore`; only the hook scripts themselves are committed). This works
+  because npm keeps `web/node_modules/.bin` on `PATH` for the `prepare` script even after
+  it `cd ..`s to the repo root (which husky's init requires — it hard-checks for `.git`
+  in the *current* directory).
+
+**The four hooks:**
+
+1. **`pre-commit`** — (a) `cd web && npx lint-staged`: runs `eslint --fix` on staged
+   `web/src/**/*.{ts,tsx}` files, then a project-wide `npm run typecheck` (`tsc -b` isn't
+   file-scoped, so it runs the full check, but only when a `.ts`/`.tsx` file is staged);
+   (b) back at the repo root, if any **`*.cs`** files are staged, `dotnet format
+   ErsatzTV.sln --verify-no-changes --include <staged .cs>` — a formatting violation
+   blocks the commit. The .cs step is **skipped entirely when no .cs is staged**, so
+   web-only commits don't pay the sln-load cost; when it does run it's scoped to the staged
+   files (~6-7s wall in practice, dominated by the workspace load).
+2. **`pre-push`** — CI-parity gate: `cd web && npm run check:api && npm run lint && npm run
+   typecheck && npm run build`. `check:api` guards generated-OpenAPI drift
+   (`ErsatzTV/wwwroot/openapi/v1.json` → `web/src/api/generated/v1.d.ts`); the full
+   lint/typecheck/build catch a staged change that breaks an *unstaged* file (lint-staged
+   only sees staged files). Any failure blocks the push.
+3. **`commit-msg`** — enforces the CLAUDE.md protocol: the message must carry a
+   `Co-Authored-By:` trailer, else the commit is rejected. Merge commits are exempt
+   (detected via `git rev-parse --verify MERGE_HEAD`).
+
+- **Worktree/subdir gotcha**: git exports `GIT_DIR` (and friends) while running hooks. In a
+  worktree or any subdir, an explicit `GIT_DIR` makes nested `git` commands mislocate the
+  working tree — `pre-push`'s `check:api` (`git diff --exit-code`, run from `web/`) then
+  silently reports "no diff" and lets drift through. `pre-push` therefore `unset`s
+  `GIT_DIR GIT_WORK_TREE GIT_INDEX_FILE` first. (`pre-commit`'s `.cs` collection uses
+  `git diff --cached`, index-vs-HEAD, which needs only `GIT_DIR` and is unaffected.)
+- **Practical effect**: a fresh `web/` `npm install` (after cloning or pulling this change)
+  installs all four hooks automatically — no separate setup step. Commits that touch only
+  non-`web/`, non-`.cs` files skip linting/formatting (lint-staged no-ops with nothing to
+  run, the `.cs` step is skipped).
