pi-ai credentials carry optional members as explicit undefined (a github.com
Copilot grant holds enterpriseUrl: undefined), and the store bridge committed
the object verbatim, so the credential store's strict validator refused the
write and sign-in failed after the provider had already authorized it.
toRecord now drops explicitly-undefined members and renders undefined array
entries null, exactly as JSON.stringify would; everything else passes through
untouched so genuinely unstorable values still fail loud at the store.
os.homedir() reads HOME on POSIX and USERPROFILE on Windows; stubbing
only HOME left the Windows lane expanding ~ into the real profile
directory and failing the fileExists assertions.
Review findings on #2509, all confirmed:
- Every writer of .credentials.yaml now waits out the record-mutation
lock (DOCUMENT_LOCK_WAIT_MS): refs and records share one file and one
lock, so a reference write or record delete contending with an OAuth
refresh must not fail at the 2s file-work default.
- api-key records are admitted before they are rendered: an empty key,
a non-POSIX env name, or an empty env value is refused at the write
instead of persisting a document the next boot rejects wholesale.
- llm-pi-ai no longer lets the credential-key grammar reject legal
route ids: reads answer "nothing stored" via isCredentialKeySegment
(new dsh-credentials export), deletes have nothing to remove, and only
a write refuses, as LlmError UNSTORABLE_PROVIDER_ID; flow registration
skips a future catalog id outside the grammar instead of failing the
mount.
- authorization/settled fans out with contained listener failures on
the credentials seam's terms (INVARIANT still rethrows), so a broken
watcher can never turn a finished attempt into a failure.
- notify() is fire-and-forget at the seam: a surface that cannot render
a notice loses the notice, never the attempt.
- A declined prompt is an outcome: interactions reject with the new
AuthorizationDeclinedError and the attempt settles cancelled instead
of failed.
- NOT_COMMITTED now confirms a commit observed during the attempt
(credentials/record-updated for the flow's key), so a re-auth cannot
pass a stale record off as fresh; a flow that deletes its record is
refused on the same code.
READMEs, the subsystem/event/config catalogs, and the Agent Note follow
the shipped behavior; memory.ts carries the dedup TODO.
pi-ai's auth model reaches this adapter through three translations, all
of which live here: a CredentialStore over the harness credential
records, an AuthContext over the credential plane and the host
filesystem, and one authorization flow per installed provider that
ships a login. The seams they consume name nothing from pi-ai, so a
second adapter family can arrive with a different auth model and share
them.
Every collection is now built with the store and the context rather
than with nothing, which is what makes a signed-in provider stay signed
in across the collection rebuild a configuration change causes. With a
posture that works, the configurable-provider directory no longer
withholds OAuth-only routes and `openai-codex` is offered again; the
predicate that withheld it is gone.
The credential plane stays optional. Reads answer "nothing stored"
without a credentials service because such a composition genuinely
holds no credential, while writes refuse by name — a login whose grant
evaporated would report success and then fail every request. Flow
registration is scoped to the authorization seam, so a headless or ACP
composition mounts with no sign-in and everything else unchanged.
Two fixes found while wiring this up: pre-release credential fixtures
in the llm suites still used the flat document the record work
replaced, and a flow that ignores its cancellation signal would have
held its key for the life of the process — withdrawal now settles the
attempt either way.
