Summary

  • Storage backend selectable by URL. New core storage domain: one URL (OPENHUMAN_STORAGE_URL, else a new [storage] url in config.toml) picks a tinystoragedrivers backend: memory, sqlite:<path>, mongodb://…/<db> or file:<dir>. Each driver is a Cargo feature (storage-sqlite, storage-mongodb, storage-file), forwarded through embed → tinyhumans → cli.
  • Session stores on that backend. openhuman_rpc::session_store::install_for_host() (called by the server shims and the TUI) opens the configured backend and installs TinyAgents' DriverSessionStores over it. Every agent's transcripts, turn states, records and journal then live there, one storage scope per agent. This is the cloud/SaaS persistence path (agent id = scope).
  • Desktop is unchanged. With no URL configured, it is today's install(): the classic session_raw/ / session_db/ / turn-state layout under the workspace, untouched. None of the new features are in the shipped product.
  • Vendor bumps:
  • One copy of the storage crates. A new [patch."https://github.com/tinyhumansai/tinystoragedrivers"] points tinyflows' git dependencies at the copy tinyagents vendors, as is already done for tinytools. The graph has one DocumentStore trait and one libsqlite3-sys.

Problem

  • OpenHuman's persistence is concrete files and rusqlite calls under the workspace, so one process can't serve many users from a shared database. That's the SaaS mode's prerequisite: one embed agent per user, its state scoped by agent id.

Solution

  • Storage domain. storage::{configured_url, url_from, open, install, installed, clear, scope_for_agent}. open parses with tinystoragedrivers::StorageConfig and redacts credentials in logs. A URL for a driver the build lacks fails at boot, naming the feature. scope_for_agent is the same mapping DriverSessionStores uses, so later domains agree on scopes.
  • install_for_host / install_for_url.
    • No URL keeps the classic store.
    • A URL opens the backend, installs it in the storage slot, and installs DriverSessionStores::new(backend).recover_on_open(driver != "mongodb"). Startup recovery runs on first open only for single-process backends, because another process may own a turn in MongoDB. For the same reason the boot orphaned-run sweep (agent/tinyagents/reaper.rs) is skipped on a shared backend (storage::installed_is_shared).
    • A URL that can't be parsed or opened fails the boot rather than silently writing to local files.
  • Config. [storage] (StorageConfig { url }). Its Debug redacts URL credentials, and it is bootstrap config, never read from storage.
  • Trade-off, deliberate: this PR does not move the desktop onto the ports. The classic layout stays the default; per-domain stores (approvals, devices, notifications, cron, flows, secrets) follow in later PRs, each behind the same backend.

Submission Checklist

  • Tests added or updated:
    • storage/mod_tests.rs: env vs config precedence, blank values, open memory, refuse garbage, the slot, agent scopes.
    • config/schema/storage_tests.rs: defaults, TOML parsing, credential redaction.
    • session_store/mod_tests.rs: a URL installs isolated per-agent stores; no URL keeps the layout; an unusable URL fails.
  • Diff coverage ≥ 80%: confirmed by CI changed-line coverage.
  • Coverage matrix updated: N/A, no user-visible feature row changes (the desktop path is unchanged).
  • Affected feature IDs: N/A.
  • No new external network dependencies: MongoDB is reached only when a mongodb:// URL is configured and the storage-mongodb feature is built; tests use memory.
  • Manual smoke checklist: N/A, the default desktop behaviour is unchanged.
  • Linked issue: N/A, part of the storage-drivers migration plan.

Impact

  • Desktop / CLI / TUI: no behaviour change without a storage URL. The TUI and server shims now await install_for_host(), which first reads the config (and still falls back to the classic layout if the config can't be loaded).
  • Cloud: OPENHUMAN_STORAGE_URL=mongodb://…/openhuman with --features storage-mongodb puts all agent session state in MongoDB, isolated per agent.
  • Dependencies:
    • tinystoragedrivers (the facade, with no drivers by default) is a new core dependency, and tinyagents-session gains its storage-drivers feature.
    • storage-mongodb pulls the MongoDB driver only when enabled. Each gate was built separately: cargo check -p openhuman --features storage-{sqlite,file,mongodb}.
  • Durability note: from tinyagents#348 and tinyflows#109, sessions.db, flows.db and jobs.db now open through the driver with WAL and synchronous = NORMAL. A process crash loses nothing; an OS crash or power loss can roll back the newest commits, and the databases stay consistent.

Summary by CodeRabbit

  • New Features
    • Configure storage with OPENHUMAN_STORAGE_URL or [storage] url. SQLite, MongoDB, file, and memory backends are available when enabled.
    • Sessions can use the configured backend with separate storage scopes for agents. Without a storage URL, the classic on-disk layout remains in use.
  • Bug Fixes
    • Invalid or unavailable storage backends now report errors rather than silently falling back to local files.
    • Sensitive URL details are masked in configuration output and snapshots. Storage URLs are also encrypted when configuration encryption is enabled.
  • Documentation
    • Added guidance on storage setup, supported backends, and session storage behavior.

The server and TUI now call install_for_host, which keeps the classic

📝 Walkthrough

Walkthrough

The change adds configurable storage URLs, storage-driver features, and process-wide backend management. Host startup installs a driver-backed session store when a URL is configured. Configuration handling redacts and encrypts storage URLs. Shared backends skip orphaned-run recovery. Dependency patches and CI records are also updated.

Changes

Configurable Storage Backends

Layer / File(s) Summary
Storage configuration and secret handling
crates/openhuman-core/src/config/schema/*, crates/openhuman-core/src/config/schema/types/*, crates/openhuman-core/src/config/schema/load/secrets.rs, crates/openhuman-core/src/config/ops/loader/snapshot.rs, crates/openhuman-core/src/config/ops_loader_and_search_tests.rs
Adds an optional storage URL to Config. Debug output and configuration snapshots redact sensitive URL parts. Configuration loading encrypts and decrypts the URL. Tests cover defaults, TOML parsing, encryption, and redaction.
Backend selection and driver availability
Cargo.toml, vendor/tinyagents, vendor/tinyflows, scripts/ci/checkout-submodules.sh, crates/openhuman-app/Cargo.toml, crates/openhuman-core/Cargo.toml, crates/openhuman-core/src/lib.rs, crates/openhuman-core/src/storage/*, crates/openhuman-embed/Cargo.toml, crates/openhuman-tinyhumans/Cargo.toml, crates/openhuman-cli/Cargo.toml
Adds storage-driver dependency patches, nested submodule checkout, and feature forwarding. The storage module selects a nonblank environment URL before the configured URL, opens the backend, manages the shared backend, and maps agent IDs to scopes. Tests cover URL selection, backend management, and scope mapping.
Storage-backed session-store installation
crates/openhuman-rpc/Cargo.toml, crates/openhuman-rpc/src/session_store/*, crates/openhuman-rpc/src/server/shims.rs, crates/openhuman-tui/src/runner.rs, AGENTS.md
Adds host and URL installation paths. A configured URL opens a backend and installs DriverSessionStores; no URL uses the existing local store. Recovery on open is disabled for MongoDB. Server and TUI startup await host-specific installation. Tests cover memory storage, local fallback, and invalid URLs.
Shared-backend run recovery
crates/openhuman-core/src/agent/tinyagents/reaper.rs, crates/openhuman-core/src/agent/tinyagents/reaper_tests.rs
Skips orphaned-run recovery when the backend is shared. Tests check that a running run remains unchanged for a shared backend and is reaped for a non-shared backend.

Ancillary Updates

Layer / File(s) Summary
Network tool byte-limit expectation
crates/openhuman-core/src/tools/impl/network/host_tests.rs
Updates the expected max_bytes description to say that the limit applies to returned text, with a default of 1,000,000 bytes.
Runtime-boundary baseline entries
scripts/ci/agent-runtime-boundary-baseline.json
Updates recorded match line numbers and adds baseline matches for two upstream re-exports.
Dependency-floor record
scripts/kernel-floor.limits, scripts/ci/check-dep-sim-calibration.sh
Records the flows dependency-floor reduction and lowers the package, crate-name, and native-build limits.

Merge Risk

Merge Risk: 🔵 Low · up to 8ff9d

This change adds opt-in storage backends while keeping the existing on-disk layout as the default. One remaining edge case is not yet fixed. If the backend URL is set only in config.toml and that file cannot be read at startup, the server falls back to local files and logs only a warning. The change is mergeable, but the owner should be aware of this fallback.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 8ff9d

The optional backend changes where sensitive conversation data lives. Configuration-read failures can select local files instead, while some data-access paths still use the old location. Transport protection and multi-user isolation are not fully verified. The default desktop setup is preserved.

Retained concerns

  • Medium · security · inferred: When no environment override exists, a configuration-read error is converted into an absent storage URL and installs the classic shared-workspace provider. If that initial read fails transiently and the subsequent core configuration load succeeds, startup can continue without installing the backend configured in that file. This can bypass the selected persistence destination and per-agent ownership model. Environment-pinned deployments avoid this branch, and backend-open or storage-secret decryption failures have separate fail-closed handling.
  • Medium · architecture · observed: Configured agent-session writes move to provider-owned storage, but public thread history, turn-state and replay paths still resolve workspace files. The configured backend therefore is not authoritative for the full session lifecycle, creating record-ownership and audit/replay drift. This limitation is documented and opt-in; cross-user disclosure through these unchanged readers has not been established.

Security review details

Security Blast Radius

  • inferred — The selected backend receives provider-managed transcripts, turn states, records and journals for agents using that process binding. Its database credentials and transport policy therefore affect that deployment's session data, not merely one request. Agent scopes partition records logically; authenticated tenant isolation and production database privilege boundaries remain unverified.

Security Findings and Attack Paths

  • observed — No verified retained security finding is supplied. The MongoDB TLS candidate is deferred, not a proven plaintext-transport vulnerability: the host delegates opening to tinystoragedrivers, whose exact connection implementation is unavailable. The visible URL source is process environment or configuration; this trace does not establish remote-request control of the destination.

Trust Boundaries and Controls

  • observed — The host delegates agent scope construction to DriverSessionStores. A memory-backed test writes Alice's turn and verifies Bob cannot read it, providing counterevidence to ordinary cross-agent leakage. This does not prove MongoDB-specific isolation or that every authenticated user receives a distinct agent identity; unscoped contexts use the shared default.

Resilience and Maintainability Implications

  • observed — Backend and bridge construction errors occur before publication, limiting partial installation. Publication nevertheless uses separate process-global slots, and server startup has no owner-bound restoration around a later build failure. One-runtime-per-process controls constrain supported concurrency; an unsafe retry or concurrent-host exposure was not demonstrated.

Hardening Proposals

  • proposed — Separate an explicitly absent storage configuration from an unreadable configuration. Deployments requiring configured persistence should fail startup rather than select the classic provider when the selection cannot be established.
  • proposed — Before treating configured storage as a multi-user deployment contract, route session readers through the same ownership-aware provider and verify principal-to-agent uniqueness. Validate the exact MongoDB TLS configuration and recovery behavior against the pinned dependency revision.

tests

  • Conclusion: Success
  • Scope reviewed: all assigned evidence
  • Lane summary: This revision closes nearly all prior findings: the storage patches point at real vendored crates, decrypt fails closed for the storage URL, the backend is restored/cleared around tests and classic-layout installs, the bridge is installed before the backend slot, the calibration floor is synchronized, env/config resolution is tested, and redaction covers query strings. What still stands is that an unreadable config file silently falls back to the classic layout even though a storage URL may be configured in it, and that no test boots the real server with a storage URL, so the wiring in server/shims.rs is exercised only through unit tests on install_for_host/install_for_url. With those two caveats the change looks safe to merge.

description

  • Conclusion: Success
  • Scope reviewed: all assigned evidence
  • Lane summary: The revision resolves the earlier findings: the app workspace mirrors the storage patches, the decrypt path fails closed, query/fragment redaction is in, the backend installs only after the bridge builds, tests restore the process slots, install_for_host's env/config resolution is tested, and the calibration floor is synced. One coverage gap remains: no test boots the actual server shim with a storage URL configured; the new tests only exercise install_for_url/install_for_host directly.

  • Conclusion: Neutral
  • Scope reviewed: all assigned evidence
  • Lane summary: The storage-URL host path is now implemented and covered by unit tests, but the review's standing gap remains: no end-to-end test boots the running server with a storage URL configured, so the externally visible behaviour of `install_for_host` (env override, fail-closed boot, storage-backed sessions) is driven by nothing above unit level. Also, an unreadable config still silently falls back to the classic layout. Two findings carried forward; the backend-restore and patch-mirror findings from earlier cycles are fixed.

Storage URLs can embed database credentials, so they are now encrypted
through the secret store on save and decrypted on load like other
secrets. Snapshot output redacts the URL, and redaction also strips the
query string and fragment since those may carry tokens.

Adds a test asserting that redact_url masks query strings and fragments in
storage URLs, including credentials embedded in the authority, so that
tokens cannot leak through debug output.

…backend only after bridge start

Loading the config to resolve the storage URL now propagates errors instead of
silently falling back to the classic on-disk layout, since a failed load may be
hiding a configured `[storage] url`. Installing a URL also clears any previously
installed backend and only promotes the new one once the session store bridge
has started, so storage operations never target a half-initialised backend.

Add tests asserting that snapshot_config_json strips credentials from the
storage URL and that restoring the classic layout clears a previously
installed backend. The Cargo.lock and formatting changes are incidental.

Decrypting the storage URL now restores the sealed ciphertext if the
secret store cannot open it, so the storage backend fails closed at boot
instead of silently falling back to the classic on-disk layout. The host
session store also keeps booting on the classic layout when the config is
unreadable, since remote deployments pin the backend via the environment
variable, and the CI calibration script tracks the reduced flows graph.

The test helper now refers to the storage backend trait through the
openhuman_core re-export instead of the tinystoragedrivers crate directly,
keeping the test aligned with the type used by the install call it pairs with.

…rypt

Adds a test asserting that an encrypted storage URL round-trips through
encrypt/decrypt and that decrypting with a key that cannot open the
ciphertext leaves the sealed value intact rather than clearing it to
None.

Adds a README section clarifying that a configured storage URL only moves what the installed SessionStoreProvider serves, and that host readers still resolving workspace paths directly have not migrated yet. This sets expectations that a storage URL is opt-in and not yet a drop-in for the desktop layout.

Restore the environment variable even when install_for_host panics or the test fails early.

The test changes a process-global environment variable. The restore code runs only after both calls return. install_for_host is async and could panic. The SLOTS mutex serializes only tests in this file. Other tests in the process that read OPENHUMAN_STORAGE_URL can still race with these set_var calls.

Use a drop guard that restores the variable and global state. Use a shared env lock for any other test that reads this variable.

The boot-time reaper now leaves non-terminal runs alone when the installed
backend can be shared between processes, since a run in that state may still
be driven by another replica and cancelling it would hide the run from active
and late-attach status. The shared-driver check is centralised in the storage
module and reused by the session store's recovery path.

Added the `driver_is_shared` and `installed_is_shared` helpers to the storage README, noting that boot-time recovery such as the orphaned-run sweep is skipped when the backend may be written by other processes.

@senamakel I’ll trigger an incremental review of the new changes. scripts/ci/check-dep-sim-calibration.sh now sets EXPECTED_NAMES=313 and references flows:335:313:2.

Commit 8ff9d3aea6 only changes storage documentation. The review will check the shared-backend reaper skip in the implementation.

Fail boot when storage configuration cannot be loaded

When OPENHUMAN_STORAGE_URL is not set, an unreadable configuration is converted into None, causing install_for_url to install the classic on-disk store and return success. This silently changes the selected persistence backend and can make a deployment write to local files instead of the configured storage. Propagate the configuration error instead of falling back to the classic layout.


Additional tests observation

priority medium uncertain

Fail or surface the boot when the config holding the storage URL is unreadable

[RULE] silent-fallback

The fallback is now documented and logged (this revision added the warn), which is an improvement, but the behaviour is unchanged: a deployment whose [storage] url lives in a config that cannot be read boots on the classic local layout with only a warning, silently writing durable state to disk that was meant for the shared backend. The README's own claim — "A URL that cannot be parsed or opened fails the boot rather than falling back to local files" — does not hold for a URL that cannot be read. Either fail the boot, or log at error level with an explicit marker a deployment can alert on. I keep this at medium because the code changed (the warn and comment were added) but the consequence did not.

priority medium security confident

Propagate configuration-load failures before selecting local storage

install_for_host catches configuration-load errors and returns None, which installs the classic on-disk store. Once this call replaces the unconditional classic installation, an unreadable configuration can silently route sessions and transcripts to local files instead of the configured backend, potentially splitting or exposing data. Configuration-load failures should abort boot, or the fallback must be limited to an explicit no-configuration case.


Additional critique observation

priority medium confident

Do not silently fall back when storage configuration cannot be read

[RULE] silent-fallback

This activates install_for_host, whose configuration resolution falls back to the classic on-disk layout when load_config_with_timeout() returns an error. If a deployment has a configured storage URL but the config is unreadable, the server will boot and write to the wrong backend instead of failing, potentially splitting or hiding session data. Propagate configuration-load errors for deployments that require configured storage, or otherwise make the fallback an explicit, safe policy.


Additional tests observation

priority medium likely

Boot the real server once with a storage URL configured

[RULE] missing-e2e-coverage

Still no test drives the actual server boot path with a storage URL set: the new unit tests cover install_for_url and install_for_host in isolation, but the one line in shims.rs where the server calls install_for_host().await? before builder.build() is exercised only by every existing server test implicitly with no URL. A test that sets OPENHUMAN_STORAGE_URL=memory and boots the server once (then asserts the session store provider is the driver-backed one) would pin the order of operations this PR depends on — store installed before the runtime boots, so its recovery sweep runs against the right backend.

[RULE] config-error-handling ·

// An unreadable config keeps the desktop booting on the classic
// layout, as it always has. Remote deployments pin the backend
// with `OPENHUMAN_STORAGE_URL`, which never reads the config.

Do not silently fall back when the storage configuration cannot be read

If the config file exists but cannot be read/decrypted, a deployment whose [storage] url named a remote backend quietly boots on the classic on-disk layout — state is written where the operator did not point it, with only a warn log. Earlier cycles raised this; it stands. Note the same file's own fail-closed argument ('A deployment that asked for a backend must not quietly fall back to local files') is defeated by this path. Distinguishing 'no [storage] section at all' from 'config unreadable' is the fix; a warn-and-fall-back is defensible only for a config with no storage section.

P1 Badge Edit the driver-backed transcript, not workspace files

When a storage URL is enabled, runtime_session.rs:1425-1429 writes the live conversation through this provider, but threads/ops/edit.rs:250-266 still locates and reads a workspace JSONL and constructs a FileTranscriptLocator. Consequently, openhuman.threads_edit_message and openhuman.threads_regenerate either report that a clean storage-backed thread has no transcript or, when old JSONL files remain after enabling the URL, truncate stale history while the model resumes the unchanged driver transcript and appends the replacement prompt to content that should have been removed; resolve and truncate the installed locator for the thread's agent instead.
