people whose nightly install cannot load cannot reach its update controls. npx t3@nightly unfuck starts an installed claude/codex recovery session with machine context, published-release checks, channel and data preservation, and approval before replacement or process changes. without either agent it prints manual guidance and saves the prompt.

reuses the current shared triage session writer, preserving cli and in-app triage. no contracts or bundling changes.

verified on separate linux x64 boat machines with the branch's production cli bundle:

machine	path	result
bx_9yh5gqfm	npm nightly server, codex gpt-6.1-sol low	asked desktop vs cli/server, read published releases, requested approval before resuming the stopped server; approved resume restored http 200 on the same nightly
bx_a3y56b8x	npm nightly server, claude haiku 5.5	same checks; explicitly requested approval for resume and any later restart; approved resume restored http 200
bx_seh7nvv9	no supported agent executables	printed manual recovery guidance and saved prompt/context; created no database or server
bx_qwgbfrxs	existing triage, codex luna	loaded the triage playbook and asked what went wrong

settings.json, statev2.sqlite, and its wal were sha256-identical before and after recovery on both nightly machines. both providers kept 0.1.7-nightly.20261102.4093 because it was the newest published nightly. the online recovery playbook returned 404 before merge, and both used the bundled copy. all four machines were deleted.

before: identified server alive but stopped; environment request timed out
agent: proposed exact process changes and waited for approval
user: approved only SIGCONT for the two identified processes
codex + haiku: HTTP 200; same version/channel; settings/db/wal hashes unchanged

runtime transcript, approval prompts, and complete hashes. blacksmith vp run check:changed passed on the current head cf73434894 (format, lint, knip, graphql, 40 typechecks, 3 test files); production cli bundle exercised above.

unverified: desktop replacement, global npm/standalone/package-manager replacement, windows/macOS, remote/tunnel clients, and project/thread rendering after recovery. on windows/macOS, run the built branch cli against an isolated copy of a t3 home and a broken same-channel install; compare settings/db hashes, check the proposed asset/version/channel, decline changes first, then approve the exact repair and reopen the client to confirm projects and threads. cursor, grok, opencode, and antigravity adapters are unchanged and are not launcher options.

model: gpt-6.1-sol. harness: codex.

Reviewed with sol-loop: 3 rounds with gpt-6.1-sol at high. Verdicts: approved, approved.

Walkthrough

The CLI adds t3 unfuck for broken installs. It creates a recovery session with command-specific prompts and guidance. The recovery instructions require approval before repairs, preserve T3 data, and verify the app or server after recovery.

Changes: T3 install recovery

Layer / File(s)	Summary
Recovery guidance .github/recovery/PLAYBOOK.md, apps/server/src/triage/recoveryPrompt.ts, docs/user/updating.md	Adds instructions for identifying the affected install, selecting a published fix, obtaining approval, preserving data, verifying recovery, and escalating when repair cannot proceed. The user guide explains how to run npx t3@nightly unfuck.
Command-aware prompts and sessions apps/server/src/triage/triagePrompt.ts, apps/server/src/triage/triageSession.ts, apps/server/src/triage/triagePrompt.test.ts, apps/server/src/triage/triageSession.test.ts	Passes the selected command into prompt and context generation. unfuck creates a recovery seed prompt. Tests cover both commands and verify that session setup leaves existing database and settings contents unchanged.
CLI command wiring and agent selection apps/server/src/binCli.ts, apps/server/src/cli/triage.ts	Registers unfuck and shares command handling with triage. Agent selection and fallback output identify the selected command. The unfuck fallback also prints recovery instructions.

Confirm the affected T3 home before using recovery paths

If desktop uses a custom T3CODE_HOME that the terminal does not inherit, npx t3@nightly unfuck reports the CLI’s home as the state, database, and log paths. It can also report an unrelated server or no server. Label these paths as CLI-derived and ask the agent to confirm the affected home before using them.
