Fix a git worktree that landed INSIDE the repo instead of the sibling worktrees directory. Use when: (1) you ran `git worktree add <relative/path> <branch>` from within the repo and the worktree appeared at `<repo>/<relative/path>` instead of a sibling like `<repo>.worktrees/<name>`, (2) your convention keeps worktrees in a sibling dir (e.g. `project.worktrees/feature/x`) but a new one nested under the repo root, (3) a nested worktree is now polluting `git status` / risks being tracked. Root cause: `git worktree add` resolves a RELATIVE path against the current working directory (the repo root when run from inside), not against the repo's parent. Fix with an absolute path, or relocate a mistaken one with `git worktree move`.

Repo stays on its default branch; branch work lives in a sibling <repo>.worktrees/ dir. Drift detection and recovery.

Tell a GitHub Actions outage apart from a workflow file you broke, and get the PR unstuck without bypassing branch protection.

Diagnose a GitHub Actions job that fails to assume an AWS role by OIDC with "Not authorized to perform sts:AssumeRoleWithWebIdentity" even though the trust policy allows the whole org and every sibling repo works: GitHub is migrating the OIDC subject claim to the immutable form repo:ORG@ORG_ID/REPO@REPO_ID, which a repo:ORG/* StringLike cannot match. Covers reading the real sub claim without printing the token, the sub_claim_prefix API that finds it with no CI round trip, and the forward-compatible trust-policy patch.

Reorganise Grafana folders with the terraform provider when several terraform states deploy into one workspace, without losing a live dashboard: API-create then `import` shared folders (one state creating them 412s the others), in-place moves (only `uid` is ForceNew), retire a folder in two applies (a same-apply destroy runs first and Grafana cascade-deletes the dashboards), `-target` skips import blocks, and pin data-source uids so dependent dashboards do not plan as replaced.

Adopt a hand-installed macOS app into a Homebrew cask and get past the three ways it silently fails. Use when: (1) brew install --cask <app> --adopt dies on 'chgrp -hR admin ... exited with 1' with hundreds of 'Operation not permitted' lines even though sudo took the password, (2) sudo brew is refused as 'extremely dangerous and no longer supported', (3) a retry fails with 'hdiutil: attach failed - Resource busy' or 'Download failed', (4) an agent shell hits 'sudo: a terminal is required to read the password', (5) brew output piped through tail looks clean but the app version never changed. Root cause of (1) is macOS App Management (TCC) on the terminal app, not file permissions; root does not bypass it. Covers the App Management grant and relaunch, the no-adopt alternative that keeps user data, and detaching the leftover DMG.

Keep timestamps aligned when joining many audio files into one: a lossless concat keeps every piece's gapless padding, so a transcript built from measured durations drifts later and later. Covers why frame counts do not fix it, when to encode once, and how to verify drift.

Serve one LLM call from an ordered list of vendors so a rate limit, a dead key, or an out-of-credits account fails over instead of failing the request. Covers the ordered-config to LiteLLM Router mapping, which Router knobs earn their keep (cooldown_time, allowed_fails, context_window_fallbacks, per-deployment budgets) and which to leave alone, the invisible dead fallback that reads as random flakiness, what must not be waterfalled, and how to prove failover actually happens.

Diagnose and clear a system-wide file-descriptor exhaustion on a macOS workstation caused by orphaned `mcp-language-server` (LSP-to-MCP bridge) processes leaking file descriptors until the kernel file table is full. The symptom masquerades as whatever tool happens to open a file next - "ENFILE: file table overflow" from a CLI, terraform failing, DNS lookups timing out - so it reads as that tool's bug, not the machine's. Use when: (1) any process on a dev machine dies with `ENFILE: file table overflow` or errno 23, (2) unrelated tools start failing at once with open/socket errors while the machine otherwise seems fine, (3) `sysctl kern.num_files` is within a few percent of `kern.maxfiles`, (4) `ps` shows many `mcp-language-server` (or other per-session MCP bridge) processes with PPID 1. Verified 2026-08-19: 20 orphaned bridge processes held 255,298 fds (kern.num_files 275,146 of kern.maxfiles 276,480 - 99.5%); killing them dropped usage to 19,885 and the failing tool ran clean.
