feat(security): secrets and credentials on the storage backend - #7183
Conversation
Add a storage_master_key helper that returns the master key used to encrypt secrets on a configured storage backend, reusing the key loaded by init_master_key when present and otherwise resolving it once from the environment, key file, or OS keychain. When no source provides the key it fails closed so storage secrets are never written unencrypted or under a freshly minted key that would orphan existing ones. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The tinystoragedrivers dependency now enables its secrets feature so the storage layer can back the new secrets module. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The keyring get, set, and delete operations now use the storage-backed secret store when the host has configured one, falling back to the process backend otherwise. The process-only paths were split into process_get, process_set, and process_delete so that the availability probe and app-level keys stay bound to this process, and is_available now reports true whenever a storage backend is installed since those secrets no longer depend on the OS keychain. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Register the new secrets crate in the lockfile and wire it into the tinystoragedrivers dependency set. The crate provides encrypted secret storage backed by chacha20poly1305 and hkdf. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The InvalidUtf8 error now carries the underlying FromUtf8Error so callers can inspect the original failure instead of only the key name. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
HTTP credentials and auth profiles now read and write through the encrypted secret store when a storage backend is active, falling back to the existing files otherwise. Blocking helpers were added to the secrets module so the synchronous credential stores can use the async backend. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The ChaCha20-Poly1305 encrypt and decrypt paths in the keyring now call tinystoragedrivers' secrets::crypto instead of using the cipher directly, so the config store and secrets file share one implementation and format. A cipher_key helper centralises loading the key into the fixed-size array the cipher expects. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Drop the unused chacha20poly1305 imports from the encrypted store module, since the encryption code no longer references them directly. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

The test asserted a condition that always holds in the lib test binary, so it provided no real coverage. Removing it keeps the suite focused on meaningful checks. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add a Cargo test target for the new storage secrets end-to-end test so it runs in its own binary, since it installs a storage backend into the process-wide slot and sets the keyring master-key environment. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Reformat keyring crypto and ops, credential profile persistence, and secrets tests to satisfy rustfmt, collapsing wrapped calls onto single lines and removing stray blank lines. No behaviour changes. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Regenerate the lockfile to include the new tinystoragedrivers-secrets crate and its dependency edge from tinystoragedrivers. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The storage, keyring, and credentials READMEs now describe how secrets and credential files are stored as encrypted documents in the acting agent's scope when a storage backend is configured, including the HKDF-derived per-scope data key and fail-closed behaviour without a master key. This records the behaviour so the modules' docs match what the code does. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Tiny Sweeper reviewTiny Sweeper reviewed this change across 6 lane(s) and found 2 active actionable finding(s). Detailed lane evidence and any incomplete work are listed below. State: Changes requested Review snapshot
Completeness: Complete What changedBumps the dependency-graph calibration baselines for the storage-secrets work: the expected flows-graph name count moves 313 -> 314 in scripts/ci/check-dep-sim-calibration.sh and the matching `flows:335:313:2` -> `flows:336:314:2` floor in scripts/kernel-floor.limits, both annotated as adding the first-party tinystoragedrivers-secrets crate (its crypto dependencies were already in the graph). This is consistent with the `secrets` feature enabled on tinystoragedrivers in crates/openhuman-core/Cargo.toml. Earlier calibration and dependency findings are resolved; the migration, fail-closed key handling, test-target registration and logging cleanups from prior rounds are in place. Remaining open concerns are test-hygiene only: tests/storage_secrets_e2e.rs neither restores the environment variables it sets (`OPENHUMAN_WORKSPACE`, `OPENHUMAN_KEYRING_BACKEND`, `OPENHUMAN_KEYRING_MASTER_KEY`) nor the previous process-wide storage backend after `install`, and an assertion failure prints the `dev-keychain.` file contents. Several e2e jobs are still pending. Features

Failed master key loads are no longer cached, so secrets recover once keychain access is restored, and the storage key error no longer leaks a path from the environment. Credential and auth-profile stores now adopt the existing on-disk files on first use of a storage backend so those credentials stay visible and cannot be overwritten by an empty set. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The end-to-end test now seeds classic auth-profile and HTTP credential files before a backend is installed, then asserts the backend adopts those entries instead of replacing them and leaves the legacy files untouched. It also verifies the legacy entries remain readable once the backend is cleared. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The end-to-end test now snapshots the keychain and secrets files before installing the memory storage backend and compares their contents afterwards, instead of only checking that they do not exist. This verifies the backend leaves any pre-existing secret files untouched rather than assuming they were never written. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Moved the encrypted file backend's read, write, and delete helpers into a dedicated ops module so the backend only handles keyring orchestration. This keeps the file-level crypto and IO concerns separate from the backend's credential management logic. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Migration of legacy http-credentials and auth profiles to the storage secret no longer aborts the read when the write fails; the legacy data stays readable and the next read retries the adoption. The keyring get path was also simplified to drop a redundant Option round-trip. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Extend the secrets end-to-end test to seed a value in the process keyring and verify it is adopted on first read. Also assert that deleting it clears the secret from both stores so it cannot resurface. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The end-to-end test now checks that secrets.enc is untouched and that the storage-side secret never reaches the process keychain file, rather than comparing the keychain file byte for byte. This makes the assertion about the behaviour that matters instead of incidental file contents. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Replace the match on the cached master key with an if-let so the hit path returns directly and the miss case falls through without an empty arm. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

Bind legacy credential files to the acting storage scope before adoption.
storage::secrets::current() isolates only the destination document. Both migrations still read the shared state_dir file first. Legacy secrets use the process SecretStore key, not the per-agent storage key. If agents share state_dir, one agent can adopt another agent’s legacy credentials. Give each agent an exclusive legacy path, or reject adoption unless the path is bound to the acting scope.

Propagate process-backend cleanup failures.
When storage is configured, delete ignores process_delete errors after removing the storage value. Because get falls back to the process backend on a storage miss, a failed atomic write can leave the legacy copy readable. Return the cleanup error so callers can retry.

Update delete to propagate errors from process_delete instead of logging and
ignoring them when storage is configured. Keep the existing storage deletion
behavior, but return the cleanup error so callers can retry.

Do not print the keychain file on assertion failure
Still stands from an earlier revision: the failure message interpolates the whole file content. If the assertion ever fails because the storage path leaked a secret back into the process keychain — exactly the regression this line exists to catch — the panic message dumps those secrets into CI logs. Return a count of matching lines, or assert on a boolean and print only that.

Surface why the http-credentials migration failed
Still stands from the earlier revision: the Err(_) arm discards the storage error, and the same pattern appears in the profiles migration. The warn tells the user only that a retry might happen; the underlying cause (scope unresolvable, no master key, backend error) is never logged, so an operator debugging a migration that never succeeds has nothing to go on. Log the error's Display at warn or debug level alongside the fixed message.

Do not discard process-backend errors during the storage fallback read
Still stands from the earlier revision ("Propagate process-backend errors during storage fallback"): process_get(...).ok().flatten() turns a real keychain failure (locked keychain, IPC error) into "no legacy secret", which then also suppresses the adoption attempt. The caller sees Ok(None) for a secret that exists. Distinguish "absent" from "failed": propagate the error, or log it at warn level before flattening.

Keep user-scoped details out of keyring error logs
Still stands, narrowed: the identifiers were removed from the hit/miss/ok debug lines, but the error path still interpolates the whole KeyringError and its diagnostic() string. Several variants carry the key name (InvalidUtf8 { key, .. }) and backend diagnostics routinely embed the namespaced key that failed. Under the repo rule "never log … sensitive data", the error log can still name a secret's key; the fix is to log {e}'s variant/description without {} of diagnostic() when the variant carries the key, or to log a static string plus e.diagnostic() only for variants known not to embed user identifiers.

Reuse the recorded keychain failure for storage keys
Still stands in substance: KEYCHAIN_UNAVAILABLE is now set when init_master_key fails, and storage_master_key consults it — good. But the reuse is keyed on "the keychain was unavailable at init", not on "no configured env/file key exists": try_load_master_key checks MASTER_KEY_ENV / MASTER_KEY_FILE_ENV before the keychain, and storage_master_key skips that check entirely when KEYCHAIN_UNAVAILABLE is set. A deployment that sets the env key after init_master_key already ran (so the keychain prompt was denied) is refused even though the env key would serve. This is the residual of the earlier "Resolve configured environment keys before reusing keychain failure" finding: the guard should fall through to try_load_master_key rather than fail when the failure was keychain-specific, or KEYCHAIN_UNAVAILABLE should only be set when no env/file source was configured.

Keep the legacy credential store synchronized with the backend
Residual of the earlier "Remove or synchronize the legacy credential store" finding: the legacy file is read once for adoption and then left in place, and writes after that go only to storage, so the file permanently freezes at its pre-backend content. That is now the intended design (the e2e test asserts the files are byte-identical after backend writes) and the README documents it, so the earlier "remove or synchronize" demand is withdrawn as a bug and reduced to a caution: a host that later uninstalls the storage backend (the e2e test exercises clear()) sees the stale file, and http.get("github") correctly returns nothing — but a host that toggles back and forth will adopt the frozen file again on the next first-read, reintroducing deleted credentials. If toggling is a supported flow, delete the legacy file once adoption succeeds, or record the adoption generation in the file so re-adoption cannot resurrect stale state.

Restore process-wide environment state after the test
This suite mutates three process-wide environment variables and never restores or clears them. The same binary's comment says it exists precisely because it owns the process-wide storage slot, but the environment outlives the test in whatever process runs it, and other suites in the same cargo test invocation on a shared runner can inherit a master key or file keyring backend they did not ask for. Save the previous values and restore them (or unset) when the test ends, as agent_harness_e2e.rs does with EnvVarGuard. Severity kept from the earlier finding.

[RULE] env-state-restore
Still stands from an earlier revision: this test sets three process-wide environment variables and never restores them. It is a separate binary today, but any other binary sharing the harness process group — or a future test appended to this same [[test]] target — inherits OPENHUMAN_WORKSPACE pointing at a tempdir() that is deleted at the end of the test, OPENHUMAN_KEYRING_BACKEND=file, and a fixed master key. If another target in the same run reads these after this test finishes, it sees a deleted directory and a deterministic key; if the harness runs tests in threads (which it can, for a [[test]] with more than one #[test] later), the ordering is nondeterministic. Save the old values with std::env::var and restore them in a guard that runs on scope exit, or panic-unwind-restore them, so the test leaves the process state it found.

Restore the previous storage backend after the test
The test installs a backend into the process-wide storage slot and only calls clear() near the end. If a backend was already installed before this test ran (or a later test in the same binary expects one), the prior state is gone. Capture and reinstall the previous backend, or document why clear() alone is a complete restoration. Severity kept from the earlier finding.

[RULE] test-installs-global-state
Still stands from an earlier revision: install replaces the process-wide storage slot and this test never calls anything that reinstates what was there before. It calls openhuman_core::storage::clear() near the end to exercise the no-backend path, but that leaves the slot empty rather than restoring the previous backend if one was already installed when the test started (e.g. a host harness that pre-installs one). Record the prior backend, or assert in a comment that the binary is guaranteed to start with an empty slot, and make the guarantee visible in the code rather than implicit.

When the metadata document loads but a per-profile storage read here fails transiently, crates/openhuman-core/src/security/credentials/profiles/keychain.rs:59-65 converts the error into Ok(None); storage-created metadata has no JSON token fields, so profiles/migration.rs:284-294 classifies an OAuth profile as missing its access token and lines 478-479 persist its removal if the backend has recovered. A single Mongo/network error can therefore orphan a valid credential and log the user out; distinguish a backend error from a genuine miss and abort or retry the load instead of running missing-secret cleanup.

If a malformed or legacy storage entry contains non-UTF-8 secret bytes, the FromUtf8Error retained here owns the complete decrypted buffer. KeyringError::diagnostic() formats the variant with Debug, and crates/openhuman-core/src/security/credentials/profiles/keychain.rs:59-65 writes that diagnostic to warn logs, whose derived representation includes the byte vector and makes the secret reconstructible; discard the buffer or retain only a redacted Utf8Error before returning.

When a secret was adopted from the process backend and that backend is temporarily locked or unwritable during deletion, these lines discard its removal error and return success after erasing only the storage copy. Once the process backend recovers, the next get sees a storage miss and lines 74-86 re-adopt the supposedly deleted credential, so callers can observe a secret return after a successful deletion; return an error or leave a tombstone until both copies are gone.

When a storage URL is enabled on the standard non-SaaS app/CLI/TUI launch, the root context has no session_agent, so storage::current_scope() returns the same Scope::local() before this fixed name is used. Consequently every user-scoped state_dir reads and rewrites one shared auth-profile document (and HttpCredentialsStore repeats the pattern): after switching from user A to B on one host, B loads A's metadata and missing B-namespaced keychain values can trigger cleanup that erases A's OAuth profiles; with secrets.encrypt = false, B can resolve A's token fields directly. Include the state-directory/user identity in the storage name or scope.

When an installed backend cannot build its DocumentSecrets—for example, a headless run uses process backend file without OPENHUMAN_KEYRING_MASTER_KEY and the OS-keychain lookup fails—this condition falls through to probe_availability(), which returns true for the file backend. AuthProfilesStore and consent/wallet preflights then treat the keyring as usable even though every public get/set/delete still routes to storage_secrets() and errors; detect an installed backend separately and return or cache false on construction errors rather than probing the unused process backend.

Remove the undeclared dependency feature
Cargo rejects features that are not declared by the selected package. No secrets feature declaration was found in the repository, and the referenced tinystoragedrivers manifest is not present at this commit, so this dependency cannot be verified as supporting the new feature.

Do not expose raw master-key loading errors
Making this module public compiles and exposes the storage-secret path, whose master-key failure is wrapped with the raw {error} text. Keychain or file-backend errors can contain implementation details, paths, or user-scoped identifiers and may be returned to callers or logged upstream. Map this failure to a stable, non-sensitive message while retaining the original error only in controlled diagnostic context.

Do not resurrect profiles from the legacy file
The adoption path still re-uploads the entire on-disk store whenever the storage record is absent and the file is non-empty. The file is intentionally left in place (the diff and README say so), so any later absence of the storage record — a deletion of the secret, a scope reset — makes the next read restore profiles that were removed while on the backend. Adoption should be one-shot (e.g. tombstone recorded on the backend once adopted, or the legacy file retired after a successful migration) rather than retried on every missing-record read.

Restore the environment variables this test sets
The test sets three process-wide environment variables and never restores or removes them. The binary is currently single-test, but any future test added to it (or a harness that shares the process) inherits a poisoned workspace and master key.
