Console: read-only memory-engine panel, Brain re-listed, selection-scope decision recorded

[YellowSnnowmann]

Summary

P2 + P3 of the memory-engine surfacing plan, in one PR. Stacked on #1273 (needs its MemorySpec.healthy field; review from commit 4268475b). Merge order: #1248 → #1273 → this.

P2 — the operator can finally SEE the engine

• Brain returns to the nav (parked by nav: remove Inbox, Desk, Brains and Finances from the sidebar #302, re-listed deliberately: an operator choosing between memory engines needs somewhere to look). The parked-view comments are updated to match.
• Engine panel on the Brain view: driver, mode, negotiated capability chips, and the boot probe rendered as a green / red / neutral state (reachable / unreachable — check the endpoint and credential / not probed). A hosted engine serving exactly the mandatory three families says so out loud — the spec's operator rights assume richer families that live only engine-side (the G13 surfacing half; the backend already refuses over-claims at bind, and no oc port can currently reach an unsupported family, so there is no typed-unsupported error to add yet).
• Memory engine card in Settings: the same facts as read-only InfoRows beside the Connection card.
• Both surfaces render nothing on the store default and on hosts predating the /spec memory field.

P3 — the decision, recorded where it binds

• docs/spec/runtime/memory-engine.md gains the selection-scope record: infra-operator only, instance-wide, env at boot — no per-company/per-agent selection, no API or Console setter, and why it deliberately does not follow the per-company [inference] model. The two new UI surfaces carry no setter for exactly this reason, and their doc-comments say so.

Verification

• npm run typecheck and npm run build in frontend/ — clean
• No Rust changes; no e2e spec touched (the existing memory-engine-badge testid is preserved; the new panel and card add memory-engine-panel / settings-memory-engine testids for future specs)

📝 Walkthrough

Walkthrough

The change adds configurable memory engines, boot-time health probing, /spec health reporting, read-only frontend engine panels, deployment documentation, expanded provider conformance tests, and CI coverage for the tenant feature union.

Changes

Memory engine lifecycle

Layer / File(s)	Summary
Memory configuration and deployment .env.example, .github/workflows/deploy-staging.yml, deploy/README.md, docs/spec/runtime/memory-engine.md	Memory engine variables, hosted and embedded feature requirements, deployment settings, switching procedures, and boot behavior are documented.
Boot health propagation src/store/select.rs, src/bin/opencompany.rs, src/app/types.rs, src/server/routes.rs	Provider overlays retain probe handles, perform bounded startup health checks, and expose optional health through /spec.
Memory engine presentation frontend/src/api/types.ts, frontend/src/components/app-shell.tsx, frontend/src/views/MemoryView.tsx, frontend/src/views/SettingsView.tsx	The Brain view becomes visible. Memory engine identity, backend mode, capabilities, and health appear in read-only panels.
Provider conformance and CI src/store/memory/*, Cargo.toml, .github/workflows/ci.yml, scripts/ci/feature-lanes.txt, vendor/openhuman	Embedded and hosted providers receive conformance and facade round-trip tests. CI runs these tests with the tenant feature union.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to ac213

This PR adds read-only memory-engine status surfaces and feature-enabled provider/conformance wiring; the current Rust feature path references a vendored conformance crate that is not present, which can block compilation or CI, while remote-provider health logging and transport behavior still need bounded owner follow-up. Merge should wait for the dependency path to be corrected or explicitly accepted.

I’m a rabbit with a memory bright,
Engines now wake and report their state.
CI hops through providers at night,
Brain panels show what /spec can relate.
Boot checks pause, then open the gate.

The panel is clean — three-states Option<bool> correctly, leaks nothing, genuinely read-only, and the P3 reasoning holds up against the code it cites. Two things block.

First, credit where I owe it: the staleness concern I raised on #1273 is already addressed here, and better than I expected. MemoryView.tsx:563-565 reads "reachable at boot" / "unreachable at boot — check the endpoint and credential" / "not probed", and Settings hedges structurally instead — the InfoRow is labelled "Boot probe" and the card says "read at boot", so its bare "reachable" is scoped by its own label. That clears the bar I said was owed. The only residual is that neither surface says when boot was, so "reachable at boot" on a 30-day-old pod is true but unhelpful, and the green dot still reads as "live" faster than the text beside it does. A timestamp is a /spec change so I'm not asking for it here; a less status-light-coded treatment for the dot might be worth a thought.

Major — backend === "null" renders as an ordinary healthy engine, on the one view with a write button.

MemoryView.tsx:526 and SettingsView.tsx:350 gate on backend === "store" only. But MemoryBackend::Null (select.rs:165-166, "writes accepted and discarded, reads empty") binds through open_provider, gets probed, and reports healthy: true. So an operator sees Engine: <driver> · Mode: null · green dot, "reachable at boot" — beside a working-looking "New memory" button whose writes vanish.

The host already treats this as the alarming case. select.rs:661-669 emits a dedicated warn: "OPENCOMPANY_MEMORY=null is bound: memory writes are accepted and discarded… Nothing this company is told will be remembered." — with the stated reason that every read returning empty is indistinguishable from a company that simply hasn't learned anything yet. Moving that from the pod log into the operator's eye is exactly what this panel is for, and the panel's own docstring says it exists "so an operator can see what a hosted engine does NOT support before a cycle discovers it". Rendering the loudest case as a normal green row inverts that.

One conditional fixes it — backend === "null" gets warning treatment carrying the discard sentence. I'd suppress or warn on the Add button too, but the copy is the minimum.

Major — the Brain e2e was left skipped, and its comment now says the opposite of the truth.

frontend/test/e2e/wiring.spec.ts:71-78:

"Parked by issue #302: the console no longer lists Brain… this stays here verbatim to be un-skipped the day the surface is relisted, rather than deleted and rewritten from memory."

This is that day, and the test.skip and comment are untouched. So the re-listed view and both new surfaces ship with zero automated coverage, a repo comment is now factually false, and the body's "the parked-view comments are updated to match" is incomplete.

Compounding it: EnginePanel isn't exported, so the Option<bool> → three-state mapping — a pure function, trivially testable, and the exact thing an operator's trust rests on — can't be unit-tested either. npm test is 148 files / 1417 tests; this repo doesn't ship UI logic untested. Either un-skip the wiring spec (it should pass — Console E2E runs a real host binary), or export EnginePanel and unit-test the three states plus the store/null/old-host gates.

Non-blocking

• app-shell.tsx:166 — the HIDDEN_VIEWS comment still lists memory among the parked views. The two you updated at :156 and :177 are good; this one now disagrees with them ten lines apart.
• MemoryView.tsx:584 — "Richer families (trees, graph, sources)". Both the Rust (store/memory/mod.rs:147) and this PR's own doc (memory-engine.md:69-70) say "no summary tree, no graph and no taint tier"; sources appears nowhere. Also "are not served over a hosted engine" over-generalizes from this engine to all hosted ones — the condition is mandatoryOnly, a statement about the bound engine.
• MemoryView.tsx:509 — MANDATORY_FAMILIES is a hardcoded frontend copy of a backend contract asserted at routes.rs:925-927 and store/memory/test.rs:578-580, with no coupling test. A backend rename silently stops the note rendering with nothing going red — same class as the classifier-string-drift trap.

Nits: healthy: null renders a transparent dot with no label (MemoryView.tsx:554-566) — currently unreachable thanks to skip_serializing_if, so defensive only, but an else would make the render total. The P3 section at memory-engine.md:329-339 near-duplicates the runbook paragraph three lines below it. And the memory-engine-badge pill at :231-247 now says the same thing as the panel directly beneath it — retaining the testid for the e2e is fair, but the visible pill may be redundant.

What I verified clean: no leakage — MemorySpec carries exactly backend, driver_id, capabilities, healthy, with no reason string, so there's no channel for an error message to smuggle an endpoint, and the panel renders a strict subset. All three Option<bool> states map correctly and undefined cannot render as red (checks are strict === false). Genuinely read-only on both surfaces — no setter, no mutation path, no disabled-but-present control implying a future one.

On re-listing Brain — safe. I looked up #302 and it was a pure MVP-IA declutter, which went out of its way to say "Removing the nav item is not removing the capability" and "No backend route, store or test is deleted as part of this — nav only." Not parked for being incomplete or misleading, and the premise has lapsed anyway since NAV now carries Ledgers, Approvals, Workflows, Workspace and Company. One note: this reverses a maintainer IA decision without a sign-off cited, so probably worth a ping rather than a block.

Stack drift worth catching: this doesn't carry #1273's 69dac733 ("privatize the probe handle, pin the merge commit, unclaim the union") — the commit that addresses my #1273 review. Merge #1273 first and rebase, or this PR's merge re-introduces the pre-review Rust.

CI is clean — everything green except Rust (openhuman, tinycortex) still running at normal duration, and all the Rust lanes are inherited #1273 content anyway since this PR has zero Rust. I reproduced locally: all three typecheck projects clean, npx vitest run 148 files / 1417 passed. Note Console E2E passes without exercising Brain, per the skipped spec. tinysweeper's approval is pinned one commit stale and is an embedding-only pass; CodeRabbit hasn't posted at this head. Its walkthrough bullet about "improved settings lifecycle handling" is misattributed — there's no lifecycle change, it's describing the new card's own live/setEngine(undefined) cleanup guard.

[YellowSnnowmann]

@oxoxDev Both majors are addressed in bb80e2c9, plus most of the non-blockers:

null renders as the alarming case now. enginePanelMode() classifies backend === "null" as discard: the dot goes amber regardless of the probe (green would be a lie beside a write button), and a destructive Alert carries the host's own discard sentence — accepts-and-discards, reads-come-back-empty, indistinguishable-from-never-learned, with the env var to unset. Settings' card description carries the same sentence. I stopped short of disabling the Add button — the copy is doing the warning's job and a dead button invites "is this broken?" — but happy to add suppression if you'd rather.

The Brain e2e runs again — and on the default lane, not just live-brain. Un-skipping in place would have left it gated: wiring.spec.ts is file-level test.skip(!LIVE_BRAIN) because it proves the mocked inference chain, while this flow exercises …/memory and needs no inference at all. So the test moved verbatim to its own brain-memory.spec.ts (history noted in its header), ungated — the default Console E2E job now executes it instead of skipping it. Verified locally against the real host binary: passes in 542ms. The panel logic is also now unit-testable and tested: enginePanelMode / probeLabel (total over the domain, including a literal null) / isMandatoryOnly exported pure, 9 new tests, suite at 150 files / 1427.

Non-blockers: app-shell enumeration fixed; families copy now says summary tree/graph/taint and scopes the claim to this engine; MANDATORY_FAMILIES carries the drift-trap pointer at the two Rust assertion sites (a generated contract is the real fix; out of scope here); the render is total (no blank label on any healthy value); the P3/runbook near-dup deduped. Kept: the pill above the panel (testid is load-bearing for the e2e, and the pill is the glanceable summary of the panel's detail).

On re-listing Brain reversing #302's IA decision: flagged to the product owner rather than assumed — the re-listing was their direct request, but your "ping rather than block" is noted in the PR body now too.

Stack drift: already healed before your review posted — the branch carries #1273's 69dac733 (and its 75dfe5d9 doc fix) via merge; merge order stays #1273 → this.

[oxoxDev]

Approving. Both blockers are genuinely fixed, and I verified them by rendering the panel and by reading the CI log rather than by inspection.

null backend — fixed. The logic routes through an exported enginePanelMode(), and I rendered EnginePanel directly across all four states:

input	dot	discard alert
backend:"null", healthy:true	bg-status-blocked (amber)	present
backend:"null", healthy:false	bg-status-blocked	present
backend:"remote", healthy:true	bg-status-done (green)	absent
store / old host	renders ""	—

Amber is a real token (--status-blocked, index.css:232) used the same way in status-pill and host-switcher, and the store/old-host gates still return null — confirmed by render, not by reading the branch. The copy carries both the meaning and the lever: "accepts and discards every write — nothing this company is told will be remembered … Adding memories here does nothing until the infra operator unsets OPENCOMPANY_MEMORY=null." Settings got the same treatment on its CardDescription. Leaving the Add button live is fine given the Alert sits directly beneath the header row that contains it and says adding does nothing.

Brain e2e — fixed, and better than what I asked for. Rather than un-skipping in place you moved it to brain-memory.spec.ts, and the reasoning holds: wiring.spec.ts:7 carries a file-level test.skip(!LIVE_BRAIN, …), so un-skipping in place would have left it gated on PW_LIVE_BRAIN. The new spec has no such gate — and it actually ran, from the Console E2E log at head:

✓ 26 test/e2e/brain-memory.spec.ts:28:1 › operator adds a Brain memory that persists across reload and can be deleted (854ms)
23 skipped / 192 passed (5.4m)

Green in the live-brain lane too. And the nine new unit tests are load-bearing — I mutation-tested them and all four mutations were caught: dropping the null → "discard" branch, inverting probeLabel, reducing isMandatoryOnly to a length check, and emptying the probeLabel fallback.

Non-blocking items: the HIDDEN_VIEWS comment is fixed, and the families copy is fixed on both halves — "summary tree, graph, taint" now matches MemoryTaint and the doc's own line 70, and "this engine serves only the floor" replaces the over-general phrasing. MANDATORY_FAMILIES stays uncoupled but now names the two Rust assertion sites in a comment; the unit test uses the constant as its own oracle so a backend rename still drifts silently — reasonable as recorded debt. The healthy: null label is total and explicitly tested, and the doc duplication is now a one-line back-reference.

Two small things for whenever you're next in here, neither worth another round:

• The blocker-1 remedy itself has no committed test — only the decision is covered. I deleted the entire {mode === "discard" && <Alert …>} block and the full suite still passed 1426/1426; nothing references memory-engine-discard, memory-engine-panel or settings-memory-engine. A renderToStaticMarkup assertion closes it in about five lines (RTL isn't installed, so react-dom/server is the path — I confirmed it works).
• SettingsView duplicates the classification inline (backend === "store" gate, const discarding = engine.backend === "null") instead of importing enginePanelMode. Two surfaces, one contract, no shared source — it drifts if a future backend adds another discard-shaped mode.

The badge pill still duplicates the panel beneath it and still renders for null in neutral styling, which is cosmetic but is the element physically adjacent to the Add button while the Alert sits below. And the null panel still reads "reachable at boot" beside an amber dot — literally true, you flagged the tension in-comment, and the Alert disambiguates immediately.

Stack drift is resolved: merge-base is exactly 75dfe5d9 and this carries 69dac733, so no out-of-order-merge risk. Gates clean locally — all three typecheck projects exit 0, npx vitest run 149 files / 1426 tests, build fine. CI fully green at head; Rust (openhuman, tinycortex) resolved to success at 30m33s — it was queue-slow, not broken, with five sibling runs of the same lane in flight simultaneously.

One caveat on the bot row, as usual: tinysweeper's approval is at a two-commits-stale SHA on an embedding-only pass (0 in / 0 out, sub-checks reporting "Reviewed 0 files"), and CodeRabbit's check reads pass on "Review rate limited". Its stale CHANGES_REQUESTED at ac213933 was never re-submitted, though it did explicitly withdraw all four inline findings at head — all of which were on #1273's Rust rather than this increment.
