Adds opt-in `ccsx auth import-default <name>` to migrate the existing
~/.codex/auth.json into a new profile, plus the cross-system integration
tests and user-facing documentation.
- import-default-command (C3 torn-write protection):
- readFileSync + JSON.parse with 3x retry / 100ms backoff to survive
Codex's truncate-then-write auth.json refresh race
- decode-id-token sanity-check on JWT shape (catches mid-write JWT
corruption that JSON.parse alone wouldn't notice)
- pgrep -f codex best-effort detection; warns + refuses without
--force-while-running flag if a live codex process is found
- rejects cliproxy-format auth files ({type: "codex", ...} wrapper)
with a clear "use ccs cliproxy ..." pointer
- atomic write to <dest>.tmp.<pid>.<rand> + rename
- --with-history defaults to false per D8 (auth-only is the safer
default; opt in for bulkier data)
- --force backs up existing auth.json to .bak-<ts> before overwrite
- non-destructive — never modifies ~/.codex/; legacy mode keeps
working without ever running this command
- integration tests:
- two-terminal-isolation: two profiles with separate CODEX_HOMEs
write to their own auth.json/history.jsonl with no crosstalk
- ccsxp-independence: codex-auth profile set; ccsxp still uses its
own CCSXP_CODEX_HOME / ~/.codex pool (H5 stderr notice present)
- legacy-fallback: no profiles registered → codex-runtime-router
leaves CODEX_HOME unset → codex falls back to ~/.codex
- import-default.integration: real fs copy + decode + register
- docs/codex-auth.md: user guide covering quick start, two-terminal
example, migration, dashboard, and caveats (cmd.exe, Windows
symlinks, ccsx vs ccsxp distinction)
155 codex-auth-scope tests green (45 Phase 1 + 57 Phase 2 + 19 Phase 3
+ 15 Phase 4 + 19 Phase 5). Full suite 3051/3082 — the 1 failure is a
pre-existing test-pollution issue between ccsxp-runtime.test.ts and
codex-runtime-integration.test.ts that exists on dev today; the test
passes in isolation.
