fix(credentials): keep profile secrets out of the interactive keyring on a file-keyring core - #8670
When the operator picks a file, encrypted_file or memory keyring (OPENHUMAN_KEYRING_BACKEND), auth-profile secrets now go into the encrypted profile document. They no longer go through TinySecurity's interactive keyring.
memory_engine_set / clearing the CortexDB key now report the whole error chain ({error:#}). Before, the cause ("keyring operation approval timed out") was dropped.
Problem
On a headless core (Docker, no OS keyring, no one to answer prompts), every profile write failed after exactly 120 s:
engine error: storing the API key failed: TinySecurity keyring set failed for profile memory-cortexdb:default
Why:
AuthProfilesStore::construct set use_keychain whenever a config was present (store_core.rs), regardless of the operator's keyring backend.
TinySecurity asks the host for fresh human consent before every keyring operation (adapter_crypto.rskeyring_inner -> consent).
The host publishes the prompt and waits MAX_CONSENT_WAIT_MS = 120 000 ms (operation_approval.rs). With no renderer, the prompt times out as Pending.
Pending is a consent error, so prepare_persisted deliberately does not fall back to the document, and the write is refused.
As a result, a headless core can never store any profile secret: here the CortexDB key, which turns long-term memory off. #8664 (module_keyring_backend) changed where the module keyring stores data for file setups, but the per-operation prompt still blocks.
Solution
keyring_selected_for_profiles(selection) parses OPENHUMAN_KEYRING_BACKEND exactly as module_keyring_backend and the host secret storage do. file / encrypted_file / memory turn the keychain off for profile stores. Unset, os or unrecognised values keep today's behaviour, so the desktop is unchanged.
The read paths (load, readonly::load_profile) already honour use_keychain = false and read document-owned secrets, so nothing else changes.
Existing records whose secret_location is Keyring keep their metadata (the existing retention in prepare_persisted). On a file-keyring host none can exist, because no keyring write ever succeeded there.
Submission Checklist
Tests added: file_keyring_backend_stores_profile_secrets_without_asking_the_keyring runs the write inside without_keyring, which refuses any keyring call with a consent-class error exactly like an unanswered prompt. RED before the fix (backend=file: keyring not asked while no one can approve it), GREEN after. config_backed_profile_store_uses_tinysecurity_and_existing_namespaced_key now pins OPENHUMAN_KEYRING_BACKEND unset so it cannot race the new test.
Diff coverage ≥ 80%: left for CI to confirm. The new function and both branches are run by the two tests above.
Linked issue: N/A, found in a production incident (Teeny's spine on a headless box).
Local run (macOS, symlink-free TMPDIR): cargo test -p openhuman --lib credentials::profiles gives 122 passed. Across credentials::, the same 4 tests fail with and without this change (openai_oauth concurrent_refresh…, scope_rollback failed_credential_rebind…, profiles::credentials x2), so they predate it. inference::provider::factory::inspection_requires_credentials_for_explicit_authenticated_cloud_routes also fails identically on origin/main.
Impact
Only headless/operator-configured keyring backends are affected. The desktop OS keyring path is unchanged.
Security: with a file keyring the operator has already chosen file-held secrets under a master key. The profile document is TSD-encrypted, which is the existing "Headless / no keychain" branch.

Bug Fixes
Profile credentials now use the configured storage backend, avoiding unnecessary keychain access when file-based, encrypted-file, or in-memory storage is selected.
CortexDB API-key storage and removal errors now provide more detailed information to help diagnose failures.
Adds a test asserting that the file, encrypted_file, and memory keyring
backends keep profile secrets in the encrypted profile document without
touching the keyring, since a headless core has no one to answer the
per-operation prompt. The existing config-backed test now pins the keyring
backend env var so it no longer depends on ambient configuration.
Auto-committed-on: macbook
Auth profiles now only use the OS keychain when the configured keyring backend selects it, instead of whenever the security module feature is enabled. This keeps profile storage consistent with the chosen backend and avoids keychain access when a different backend is configured.

…nd is selected
Profile secrets now stay in the encrypted profile document when the operator selects a file, encrypted_file, or memory keyring backend, since every keyring operation waits on a human approval prompt that a headless core can never answer, causing each write to time out and be refused.
Auto-committed-on: macbook
…db key
The error messages for storing and removing the CortexDB API key now use the alternate formatting flag so the complete error source chain is preserved instead of only the outermost message, making failures easier to diagnose.

Profile secret storage now uses the keyring whenever the security module is enabled, removing the helper that skipped it for file, encrypted_file, and memory backends. The backend selection no longer influences where profile secrets are kept.

Full summary
Pull request purpose (title): fix(credentials): keep profile secrets out of the interactive keyring on a file-keyring core. This pull request stops auth-profile secrets from being routed through TinySecurity's interactive keyring when the operator has selected a non-keyring backend (`file`, `encrypted_file`, or `memory`) via `OPENHUMAN_KEYRING_BACKEND`, so a headless core no longer waits out a 120 s consent prompt and refuses every profile write. It also widens the error chain reported by the CortexDB key store/clear paths. No push delta was available for this review.

What changed
`AuthProfilesStore::construct` now gates `use_keychain` on a new `keyring_selected_for_profiles` helper that parses `OPENHUMAN_KEYRING_BACKEND` and returns false for `file`, `encrypted_file`, and `memory` selections, leaving unset/`os`/unrecognised values on the existing keyring path. Profile secrets for those selections are therefore written to the encrypted profile document instead of the keyring. In `memory/engine.rs`, the error messages in `store_cortexdb_key` and `clear_cortexdb_key` now format with `{error:#}` so the underlying cause (e.g. a keyring approval timeout) is preserved. A new test exercises all three non-keyring selections inside `without_keyring`, and the existing keyring-path test now pins the env var unset.
Features
Added — Keyring-backend gate for auth-profile secret storage: On a headless core configured with a file/encrypted_file/memory keyring, profile writes no longer go through TinySecurity's per-operation consent prompt and instead persist in the encrypted profile document, so writes succeed instead of timing out and being refused. Desktop OS-keyring behavior is unchanged. (crates/openhuman-core/src/credentials/profiles/store_core.rsimpl AuthProfilesStore {, crates/openhuman-core/src/credentials/profiles/store_core.rsuse crate::security::secret_storage::SecretStore;)
Modified — Full error chain in CortexDB key store/clear errors: Failures from `store_cortexdb_key` and `clear_cortexdb_key` now surface the underlying cause in the engine error message rather than only the top-level keyring failure, improving diagnosability of headless keyring problems. (crates/openhuman-core/src/memory/engine.rspub async fn store_cortexdb_key(config: &Config, key: &str) -> Result<()> {, crates/openhuman-core/src/memory/engine.rspub async fn clear_cortexdb_key(config: &Config) -> Result<bool> {)
Tests
test modification — The existing keyring-path test now acquires an env guard that unsets `OPENHUMAN_KEYRING_BACKEND` before constructing the store, so it continues to exercise the keyring branch and cannot race the new test.: The tests lane reported this keeps the keyring branch covered and avoids cross-test env interference; no defect reported. (crates/openhuman-core/src/credentials/profiles_keychain_error_tests.rsasync fn config_backed_profile_store_uses_tinysecurity_and_existing_namespaced_k)

Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: The behavioural change is small and well covered: the new `keyring_selected_for_profiles` gate is pinned by `file_keyring_backend_stores_profile_secrets_without_asking_the_keyring`, which exercises all three non-keyring selections and would fail if the gate were removed (the write inside `without_keyring` would be refused), and the existing keyring-path test was updated to unset the variable so it still exercises the keyring branch. The `{error:#}` changes in `engine.rs` only widen the error chain in a message and need no new test. I found no reportable defect. _The code index is behind this pull request (indexed at `6229813dbf1f`), so retrieved context may be out of date._

The profile store now disables keychain use for file, encrypted_file, and memory backends. Tests cover profile writes and loads for these backends. CortexDB key storage and removal errors now include alternate-formatted error details.
Changes: Auth profile backend selection
Layer / File(s)
Summary
Backend selection and profile-store tests crates/openhuman-core/src/credentials/profiles/store_core.rs, crates/openhuman-core/src/credentials/profiles_keychain_error_tests.rs
The store checks the selected backend before enabling keychain use. Tests cover file, encrypted_file, and memory backends, and unset the backend environment variable in the config-backed store test.
Epic: Finish storage ownership #8427: This change adjusts auth-profile behavior for selected backends, but does not implement explicit per-user backend selection.
Possibly related PRs

Merge Risk: Moderate · up to 1a973
The change may not fully remove the headless profile-write prompt when secret encryption is enabled. Profiles already stored in a file-backed keyring can become unreachable after the upgrade. A new test can also fail intermittently in parallel runs. These should be addressed or explicitly accepted before merge.

🟡 Changes recommended
Cold encrypted profile writes can still require human approval with non-keychain backends, while process-global backend overrides can race with keyring-dependent tests and cause nondeterministic failures.
The reason will be displayed to describe this comment to others. Learn more.
Preserve access to existing file-keyring profiles
For a file or encrypted_file workspace that already has an approved keyring-backed profile, this disables reads as well as new writes. resolve_snapshot() skips those records at profiles/migration.rs:40–41, the read-only loader returns Unavailable, and removal is refused, so upgrading makes saved sessions and provider credentials inaccessible. These records can exist because module_keyring_backend() already configures an encrypted module keyring for both selections, and users can approve its operations. Retaining opaque metadata is insufficient; preserve read/delete access to existing keyring-owned records or provide a consent-aware migration before disabling that access.
The reason will be displayed to describe this comment to others. Learn more.
Isolate the override from other keyring-dependent tests
When the profile tests run in parallel, this global override can affect profiles::keychain::tests::a_save_rebuilds_a_row_whose_keyring_secret_is_unchanged, whose keyring_store() helper does not acquire TEST_ENV_LOCK. If that test constructs its store during this loop, the new backend gate sets use_keychain to false, causing prepare_persisted() to attempt field encryption with modules disabled; its unwrap() at profiles/keychain_tests.rs:258 then fails. The guard only serializes cooperating tests, so pin/unset the backend under the same lock in the other keyring-dependent tests, or exercise the selection without mutating process-wide environment state.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Do not persist fields encrypted with a transient master key.
With memory and encrypt_secrets=true, document fields use a master key held by MemoryBackend. After a restart, that backend is empty, so a profile written in a fresh workspace cannot be decrypted. Use a recoverable master for persisted fields or avoid persisting ciphertext that cannot be recovered. (raw.githubusercontent.com)

Isolate the backend environment change.
Other tests construct AuthProfilesStore::new_with_config without TEST_ENV_LOCK. They can observe the temporary backend and take the document path instead of the keyring path. For example, a_save_rebuilds_a_row_whose_keyring_secret_is_unchanged can fail its keyring assertion.
Run these cases in isolated processes or synchronize all readers.

Avoid the field-cipher prompt on headless writes.
With encrypt_secrets=true, selecting a document-backed profile sends each secret through SecretStore::encrypt_via_security. Resolving its master key still requires approval unless unattended unlock is configured and permitted. A headless write can therefore still wait or fail. The new test passes false and does not exercise this path. (raw.githubusercontent.com)
