[Phase 2] feat(hosting): add rollback, deployment history and logs - #5593
Conversation
An agent could deploy a site and could not get back off a bad deploy. `hosting_launch_site` had no counterweight: nothing promoted an earlier deployment, and nothing even returned a deployment id to promote except the launch that created it. A deploy that broke a live site was a one-way door. Three tools, all of them thin over `tinyhosts` calls that already exist: - `hosting_rollback` — points production back at an earlier deployment, via `Host::promote`. There is no separate promote tool: the crate models promote and rollback as one operation deliberately, and this is named for the reason an agent reaches for it. Carries `external_effect`, so it parks for approval like every other outward effect — opt-in per call rather than a standing capability. - `hosting_list_deployments` — the history a rollback picks an id from, newest first with status and target. Read-only. - `hosting_domain_status` — whether a site's domains are verified and serving, the read half of `hosting_add_domain`. Read-only. `hosting_rollback` reads the deployment before promoting it and refuses one that did not finish building. `hosting_list_deployments` returns failed and still-building deployments too — that is the history an agent is reading — so the id it picks is not necessarily one that can serve traffic, and promoting a failed build would take the site down during an attempt to bring it back up. It deliberately does *not* check that the deployment belongs to the named site. `Host::deployment` looks a deployment up by id alone and falls back to an empty name when the provider's response omits one, so comparing that against the site argument would refuse legitimate rollbacks. The provider owns that check. Tested against a mock of the provider's REST API, through the real adapter — `connect_to` takes a base URL for exactly this. The load bearing assertion is `expect(0)` on the promote route in the refusal case: the guard has to stop the outward call, not report an error after production already moved. `hosting_deployment_logs`, the fourth gap, is not here: `Host` has no logs method at all, so it needs a trait method, a provider implementation and a mock in the tinyhosts crate before a tool can wrap it. The other three needed no crate change. Refs tinyhumansai/opencompany#913

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds an agent-triggered rollback that can repoint live production traffic. In CLI/Docker execution, approval can be absent or disabled, and the implementation does not locally verify that the deployment belongs to the named site, leaving important safety boundaries to provider behavior; merge should wait for explicit acceptance or hardening of these controls.

Both list assertions checked for presence rather than for pairing, so each passed just as happily with the values swapped: - The domain test asserted that a `true` and a `false` both appeared somewhere in the response. Verified and pending are exactly what that tool exists to tell apart, so the one arrangement it must not report was the one the test could not see. - The deployment test asserted that both ids appeared. A list returning the right ids against the wrong statuses would point a rollback at the deployment that just broke the site. Both now parse the JSON and bind the value to its key: the domain by name, the deployment status by id. The deployment test also pins the order the crate documents, newest first. Raised by CodeRabbit on the domain assertion; the same weakness in the deployment assertion is fixed with it rather than left for a second pass.

Parked as Phase 2 — please do not merge for nowThis PR is complete and green (17 lanes, 0 failures, review thread resolved), but the work it belongs to — What it adds (in the value order the research established):
Happy to un-park it whenever Phase 2 opens; nothing here needs rework. |
The `hosting` family has never been compiled in any configuration. Its gate in
the root Cargo.toml declares its own intent:
# ... Default-OFF, product-ON: a host with no hosting credential has no use
# for the tools, and an agent that can deploy to the internet is authority a
# headless embedding should have to ask for.
but `hosting` appears in neither `scripts/ci/product-features.txt` nor the
shell's forwarding list in `app/src-tauri/Cargo.toml`, and it is not in
`default`. So 1,643 lines - including a 511-line test file and nine `hosting_*`
agent tools - are compiled by nothing, tested by nothing, and shipped in
nothing.
This is the same shape as #4901, where `voice` shipped missing to 56 users. The
feature-forwarding gate built to prevent a recurrence passes here, because it
asserts set equality between two lists and `hosting` is absent from both. A gate
cannot catch a feature nobody told it about.
It also explains the CI observation in #5593: `Rust Core Coverage` reported
success having run `0 tests; 12202 filtered out`, because the feature under test
was in no CI command.
Everything else is already wired correctly - `src/openhuman/mod.rs:29` declares
the module behind the gate, and `tools/ops.rs:1031` registers the tools. That
registration is credential-gated on `Account::from_config`, so enabling the
feature adds no tools for a host without `[hosting].api_key` or the provider's
environment variable. Users who have not configured hosting see no change.
Verified `scripts/ci/check-feature-forwarding.mjs` passes with both lists moved
together (19 shell forwards).

The recovery pathhosting_launch_sitenever had.hosting_list_deployments— the deployment history a rollback picks an id from. Read-only.hosting_domain_status— whether a site's domains are verified and serving. The read half ofhosting_add_domain. Read-only.tinyhostscalls that already exist and are already implemented against the provider. No crate change, no new dependency, no vendor pin bump.hosting_rollbackrefuses a deployment that never finished building, and the test proves the refusal stops the outward call rather than reporting an error after production already moved.Problem
An agent could deploy a site and could not get back off a bad deploy.
hosting_launch_sitehad no counterweight. Nothing promoted an earlier deployment, and nothing even returned a deployment id to promote except the launch that created the current one — so an agent that wanted to go back to the deployment before the bad one had no way to name it. A deploy that broke a live site was a one-way door.Solution
Three tools in
src/openhuman/hosting/tools.rs, following the shape of the six already there: argument parsing, one call intotinyhosts, and a result described for a model.Why there is a rollback and no separate promote.
Host::promoteis both — its own documentation says so: "a rollback is a promote of an older deployment, and modelling it twice would suggest otherwise." The tool is named for the reason an agent reaches for it.hosting_rollbackcarriesexternal_effect. It changes what the public sees on a live site, so it routes through the approval gate likehosting_launch_site,hosting_set_envandhosting_add_domain— opt-in per call rather than a standing capability.The guard, and its deliberate limit. The tool reads the deployment before promoting it and refuses one that is not ready, naming the state it refused so a model can pick a different id rather than retry the same one. This matters because
hosting_list_deploymentsreturns failed and still-building deployments too — that is the history an agent is reading — so the id it picks is not necessarily one that can serve traffic, and promoting a failed build would take the site down during an attempt to bring it back up.It deliberately does not check that the deployment belongs to the named site.
Host::deploymentlooks a deployment up by id alone, and the adapter falls back to an empty name when the provider's response omits one (into_deployment("")), so comparing that against thesiteargument would refuse legitimate rollbacks. The provider owns that check. This is recorded in the code and the README rather than left for someone to "fix" later.Nothing else needed wiring.
tools/ops.rsmatcheshosting_as a domain-exclusive prefix, with a standing comment that a NEW hosting tool auto-gates rather than falling through toPlatform— so the grant model covers these three with no edit.Tests
In
src/openhuman/hosting/test.rs, against a mock of the provider's REST API driven through the real adapter —tinyhosts::connect_totakes a base URL for exactly this case, and loopbackhttp://is accepted so a test can carry a bearer token to a server that never leaves the machine.wiremockwas already a dev-dependency.rolling_back_to_a_deployment_that_never_built_does_not_touch_production— the failure path, and the one that matters.expect(0)on the project-resolution route the promote goes through: the guard has to stop the outward call, not report an error afterwards. Also asserts the refusal names the state.rolling_back_to_a_ready_deployment_promotes_it— the happy path,expect(1)on the promote route, and the result names the deployment and where it is serving.listing_deployments_reports_the_history_a_rollback_picks_from— both a failed and a ready deployment come back; the failed one is why the agent is here, the ready one is where it is going.domain_status_distinguishes_a_verified_domain_from_a_pending_one— attached-but-unverified is the distinction the whole tool exists for.a_rollback_missing_either_argument_is_refused_before_any_callandthe_new_read_tools_report_a_missing_site_rather_than_calling_out— argument validation happens before any network call.external_effect.What is NOT in this PR
hosting_deployment_logs. It was ranked second by value and it is not here, so this is the gap to know about.Unlike the other three, it has nothing to wrap:
Hosthas no logs method at all, and neither does the Vercel adapter. Shipping it means a trait method onHost, a provider implementation against/v2/deployments/{id}/events, and a mock, all in thetinyhostscrate — then a vendor pin bump here. That is its own cross-repo deliverable, not a few more lines in this file. The other three needed no crate change, which is why they are together and it is not.Impact
