feat(memory): one check for whether memory work is free right now

[M3gA-Mind]

Summary

• Adds memory::billing::free_period_active(config) -> bool: the one check every background memory job asks before it starts on its own, i.e. whether memory work is free for the user right now.
• The answer is used by the CortexDB layout migration (old app:tinymemory tree → per-user v3) and by the v1 local-store import. Both rewrite a user's whole memory, so per the user's decision they auto-start only while it costs the user nothing.
• How it decides:
  • Not the hosted engine (self-hosted CortexDB, or a host's own engine): always free here.
  • Hosted tinyhumans engine: free only while the backend's memory free period is on (GET /memory/free-period).
  • Anything unknown (memory off, signed out, no transport, an error, a backend without the route): not free.

Problem

• Re-storing all of a user's memory on the hosted engine is billed per write and derivation. An automatic migration outside the free period would spend the user's credits without asking, and a low balance would hit 402 part-way through.
• The backend's free period (tinyhumansai/backend#1402) was invisible to clients.

Solution

• The backend now exposes it: tinyhumansai/backend#1408 (GET /memory/free-period → {active, until}, budget figures kept private).
• The core asks through the existing backend transport: BackendClient::authed_json, the credential from resolve_backend_credential, and errors through flatten_authed_error. No request is hand-built.
• The answer, failures included, is cached for 60 s per backend URL, so a job polling between batches costs about one request a minute, and a backend without the route is asked once a minute, not once a batch.
• Dependency chain (none of it blocks this PR):
  1. backend#1408: until it deploys, the call answers 404, which this check reads as not free. So nothing auto-runs, which is the safe default.
  2. feat(memory): read whether hosted memory is free right now sdk#49: adds the route to the SDK contract. The vendored SDK's route policy (vendor/tinyhumans-sdk @ 870c0d3, reject_unexposed_route) is a denylist (UNEXPOSED_ROUTES plus admin, internal and undocumented-webhook segments), so /memory/free-period already passes the transport today. The SDK bump keeps the contract in step and can follow the normal release → vendor/tinyhumans-sdk gitlink bump.
  3. Consumers: the layout migration job (OH-1, next) and W5's v1 import call this function. Neither is in this PR.

Submission Checklist

• Tests added or updated: 10 unit tests in memory/billing_tests.rs.
  • Parsing; the cache (TTL, per-backend key, failures cached).
  • Memory off → not free; a non-hosted engine → free.
  • wiremock through the real BackendClient path: on, off, and a 404 → not free.
  • The hosted engine end to end, asking the backend once.
  • Revert-check: short-circuiting the hosted branch makes the end-to-end test fail.
• Diff coverage ≥ 80%: every branch of the new module is exercised by those tests.
• Coverage matrix updated: N/A, an internal helper with no user-facing feature row yet. The consumer PRs add rows.
• Affected feature IDs listed: N/A, no matrix feature changes here.
• No new external network dependencies: tests use wiremock on loopback.
• Manual smoke checklist: N/A, no release-cut surface.
• Linked issue: N/A, this is the openhuman half of the user's billing decision (a) for the layout migration.

Impact

• Core only; no UI. One cached GET to the hosted backend, made only when a consumer asks.
• Security: rides the authenticated backend transport. The backend route exposes no budget figures.

Summary by CodeRabbit

• New Features
  • Memory usage is treated as free when a non-TinyHumans engine is selected or when the TinyHumans service reports an active free period.
  • Free-period status is reused for up to 60 seconds to reduce repeated checks. If the status cannot be confirmed, memory usage is treated as not free.
  • Checks use the configured service and account credentials, so free-period status reflects the relevant backend and account.

Features

• Added — Memory billing free-period check with per-backend, per-account cached answer, fetch-time timestamping, and envelope-tolerant parsing: Background memory jobs that rewrite a user's memory start on their own only when the work is free: non-hosted engines are always free here, the hosted tinyhumans engine asks the backend's /memory/free-period route through the backend transport, and anything unknown (memory off, signed out, no transport, an error, a backend without the route) reads as not free so nothing starts on its own. The answer is cached for 60 seconds, keyed by both the bound engine's backend endpoint and a full SHA-256 digest of the account credential so one account's answer never serves another. The cache is guarded by one async lock covering lookup and fetch, so concurrent callers wait for one request rather than each sending their own. The timestamp used for TTL expiry is read after the fetch completes, so an answer's age starts when it arrives, not when it was asked for. Backend errors are logged without the error text (which can carry the backend's response), and the parser reads `active` whether or not the response still carries the `{success, data}` envelope. (crates/openhuman-core/src/memory/billing.rs, crates/openhuman-core/src/memory/mod.rs)

Tests

• unit — Parses the free-period answer: reads the boolean `active` flag, refuses anything else, and reads an answer still in its `{success, data}` envelope the same way.: Present; each test would fail on regression. (crates/openhuman-core/src/memory/billing_tests.rs)
• unit — An answer is reused within the TTL and asked again after it goes stale.: Present; each test would fail on regression. (crates/openhuman-core/src/memory/billing_tests.rs)
• unit — An answer's freshness is timed from when it arrives, not when it was asked for: a fetch that finishes after the TTL still yields an answer that stays fresh for a full TTL.: Present; each test would fail on regression. (crates/openhuman-core/src/memory/billing_tests.rs)
• unit — An error reads as not free and is cached too, so a backend without the route is asked once a minute rather than once a batch.: Present; each test would fail on regression. (crates/openhuman-core/src/memory/billing_tests.rs)
• unit — Each backend keeps its own cached answer; one backend's answer is not reused for another.: Present; each test would fail on regression. (crates/openhuman-core/src/memory/billing_tests.rs)
• unit — Concurrent callers share one request because the single async mutex serializes misses.: Present; each test would fail on regression. (crates/openhuman-core/src/memory/billing_tests.rs)
• unit — Memory off reads as not free, and an engine other than the hosted one is always free.: Present; each test would fail on regression. (crates/openhuman-core/src/memory/billing_tests.rs)
• unit — Each account keeps its own answer: two different stored credentials against the same backend each trigger their own backend request.: Present; each test would fail on regression. (crates/openhuman-core/src/memory/billing_tests.rs)
• 2 additional supported test mapping(s) omitted by the configured limit.

tests

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Lane summary: The billing gate is now real, tested code: the module exists, the nested payload is parsed, cache keys use the full credential digest, errors are not logged and are cached, and the tests cover TTL, per-backend and per-account isolation, concurrency, and the hosted-engine wiring through wiremock. All earlier findings on those points are resolved. The one remaining concern from earlier revisions stands: nothing in the diff shows an end-to-end test driving a memory job through the free-period gate, so the invariant that gated jobs only self-start when this function returns true is still pinned only indirectly.

description

• Conclusion: Success
• Scope reviewed: all assigned evidence
• Positive: The PR adds a cached, fail-closed free-period check for memory jobs, and the description matches the diff: the module, the per-backend/account cache, the credential digest key, and the tests covering parsing, TTL, concurrency, and wiremock-driven backend paths are all present and consistent with repo rules (sibling test file, credentials via resolve_backend_credential, no error content logged). All previously raised findings — missing module source, cache scoping to backend and account, credential digest length, error logging, fetch-time timestamping, and concurrent-miss serialization — are addressed in this revision. The remaining 'end-to-end gated job path' concern is not applicable here, as no consumer exists yet and the PR states this explicitly.

The check returns false when memory is off or credentials cannot be resolved, and true for engines other than tinyhumans. For tinyhumans, it queries the configured backend and caches answers and failures for 60 seconds by endpoint and credential digest.
Billing behavior tests crates/openhuman-core/src/memory/billing_tests.rs	Tests cover response parsing, engine rules, cache expiry and isolation, concurrent requests, backend selection, and active, inactive, and failed backend responses.

🟡 Minor · Record the cache timestamp after the fetch completes. · billing.rs:132-141

crates/openhuman-core/src/memory/billing.rs:132-141
🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win

Record the cache timestamp after the fetch completes.

active_with_cache captures now before fetch().await and stores that timestamp after the fetch. If the fetch takes at least CACHE_TTL, the next caller treats the new answer as stale and sends another backend request immediately. Record the completion time instead.

Suggested fix

     let active = match fetch().await {
         Ok(active) => active,
         Err(error) => {
             tracing::debug!(%error, "[memory:billing] free period unknown; treating as not free");
             false
         }
     };
-    answers.insert(key.to_string(), (now, active));
+    answers.insert(key.to_string(), (clock(), active));
     active
