feat(github-app): validator for Connections panel (#403) - #406
Merged
Conversation
Implements the #403 panel's headless contract on the amico-run side: writeGithubAppCredentials (atomic 0600 PEM + config, same discipline as pasqal) and validateGithubAppConnection (real mint path: read file → mintAppJwt → GET /app identity check → POST /app/installations/{id}/access_tokens). Both use the same file contract (~/.amico/github.json + pem_path) that the gh shim reads, so the headless CLI path and the panel share ONE store. The validator exercises the exact surface the shim arms on next spawn — JWT signature, App existence, installation token — and maps every failure to a token-free ConfigError-shaped message (no PEM/JWT/token in output). The GET /app probe mirrors the #403 AC2 'JWT + GET /app + installation-token' triple; a 401/403/404 on /app surfaces as 'App not found or PEM mismatch'. Sandbox isolation honored via AMICO_GITHUB_FILE override (already in SANDBOX_ENV_PASSTHROUGH). No network in tests — fetchImpl injectable, same pattern as pasqal_launch.test.ts. UI wiring (Connections panel form + status card + remove path) remains fork-side and will land as the follow-up slice per #403 scope; this commit gives it the shipped-node-bundle verb to spawn (the pasqal_validate.py precedent).

Keep the active PEM and configuration as one recoverable credential generation.
Line 113 replaces the active PEM before Lines 115-123 replace github.json. If the process stops or the configuration write fails after Line 113, an existing configuration can retain the old app_id and installation_id while it references the new PEM at the same path. Validation then fails and the prior working connection cannot be recovered.
Write each new PEM to a new generation-specific path. Commit github.json with that path. Remove the previous PEM only after the configuration rename succeeds.

Fix the credential writer’s ES module and path handling.
- Replace the
require(...)calls. This package uses ES modules, sorequireis undefined whenwriteGithubAppCredentialsruns. - Resolve relative
pemPathvalues to absolute paths before storingpem_path; consumers use the stored value directly.
