feat(ai): admin-only paid OpenRouter + refresh model catalog & pricing - #1473
Merged
Merged
Conversation
Gate the paid OpenRouter provider to global admins (role === 'admin'), independent of subscription tier — a paid-tier non-admin gets no access, an admin on the free tier does. - Add ADMIN_ONLY_PROVIDERS + isAdminOnlyProvider() as the single source of truth - /api/ai/settings GET/PATCH: role-aware provider visibility; admins bypass the Pro-subscription gate (still counted against daily quotas) - requiresProSubscription() gains an isAdmin short-circuit - /api/ai/chat enforces admin-only at generation time (defense-in-depth for a demoted ex-admin's stored selection) Refresh the paid OpenRouter catalog against the live API (343 models): add current tool-capable flagships (Claude Opus 4.8, GPT-5.2 Pro/Chat, GLM 5.1, Kimi K2.6, MiniMax M3, Qwen3.7 Max, etc.) and drop 12 stale IDs that 404 on OpenRouter. Now 120 models, all confirmed live. Keep the AI_PRICING metering table in sync: add per-1M prices (from the live OpenRouter API) for every newly added model — the cost fallback is $0, so a missing entry would meter the model as free. Achieves full catalog↔pricing parity (also fills a pre-existing gap for writer/palmyra-x5). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

When an admin has an existing saved OpenRouter selection or passes selectedModel for x-ai/grok-4/x-ai/grok-4-fast, createAIProvider still sends that model ID to OpenRouter without consulting AI_PROVIDERS, but this replacement removes their AI_PRICING entries. trackAIUsage then calls calculateCost, which falls back to AI_PRICING.default (0), so those paid calls are logged as free and billing/monitoring underreports costs.

Good catch — fixed in 9776f5e (now merged into the branch). Pricing is now treated as a superset of the selectable catalog: x-ai/grok-4 and x-ai/grok-4-fast were removed from the picker but their AI_PRICING entries are retained (with a comment explaining why), so any lingering saved selection still meters at the correct rate instead of falling back to the $0 default. This also matches how the other delisted models were handled — they were only removed from the catalog, never from pricing.
Addresses Codex review (P2): removing x-ai/grok-4 and x-ai/grok-4-fast from AI_PRICING would meter any lingering saved selection at the $0 default fallback. Pricing is now a superset of the selectable catalog — entries for delisted models are retained for correct cost tracking while the models stay out of the picker.

# Conflicts: # apps/web/src/lib/subscription/__tests__/rate-limit-middleware.test.ts
The chat route now calls isAdminOnlyProvider() in the hot path. The stream-socket-events test mocks ai-providers-config, so the missing export made the call throw → route 500'd before createStreamLifecycle, failing all 13 lifecycle assertions. Add isAdminOnlyProvider to the mock (returns false). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

- Around line 433-440: The code currently uses
createSubscriptionRequiredResponse() when isAdminOnlyProvider(currentProvider)
blocks non-admins, which returns a misleading 403 message about subscription;
change this to return a dedicated admin-restriction response (e.g.,
createAdminRestrictedResponse()) or directly return the same error shape/message
used by validateProviderModel ("This provider is restricted to administrators")
so the client sees the correct reason; update the call site in route.ts (the
block using isAdminOnlyProvider) to call the new helper instead of
createSubscriptionRequiredResponse(), and add the helper function (or adjust the
existing response helpers) to centralize the 403 + correct error message for
admin-only provider rejections.
In `@packages/lib/src/monitoring/ai-monitoring.ts`:
- Around line 20-21: The new AI_PRICING entries lack corresponding
MODEL_CONTEXT_WINDOWS entries so getContextWindow() falls back to the default;
update MODEL_CONTEXT_WINDOWS to add explicit context-window sizes keyed by each
new priced model id (the exact keys from AI_PRICING such as
'anthropic/claude-opus-4.8', 'anthropic/claude-opus-4.8-fast', and the other IDs
called out in the comment) so they map to the correct token/window values, or
alternatively add a parity guard test that asserts every key in AI_PRICING has a
matching key in MODEL_CONTEXT_WINDOWS (use the existing AI_PRICING and
MODEL_CONTEXT_WINDOWS symbols and the getContextWindow() usage to locate where
to add entries/tests).

Addresses CodeRabbit review:
- Minor: the chat route's admin-only block returned createSubscriptionRequiredResponse()
("requires a Pro/Business subscription"), which is misleading — the block is on
role, not tier. Add createAdminRestrictedResponse() (403, "restricted to
administrators") and use it. Mock it in the stream-socket-events test.
- Major: every newly priced model lacked a MODEL_CONTEXT_WINDOWS entry, so
getContextWindow() fell back to the 200k default (risking truncation / provider
context-limit errors). Add accurate context windows (from the live OpenRouter API)
for all 26 new models, achieving full AI_PRICING<->MODEL_CONTEXT_WINDOWS parity.
- Add a parity guard test so future pricing additions can't drift from context windows.

…route Global assistants are per-user (not shared), so they're a primary surface for the admin-only paid OpenRouter option — and they already expose it via the footer's gated ProviderModelSelector. Add the matching backend guard to /api/ai/global/[id]/messages so admin-only providers are blocked for non-admins (defense-in-depth against a stored selection surviving a role downgrade), mirroring the page-AI chat route. Admins are unaffected (the route has no subscription gate). Update the two stream-socket-events test mocks to declare the new exports the route now consumes (isAdminOnlyProvider, createAdminRestrictedResponse).

…econcile, accounting + e2e (#1484) * fix(billing): meter all AI provider calls and bill resolved model names Close revenue leaks where AI provider calls bypassed credit metering or recorded $0 cost. Billing only happens via AIMonitoring.trackUsage → consumeCredits with a real userId and a model present in AI_PRICING. Unmetered call sites — add trackUsage (real userId was already in scope): - ask_agent (agent-communication-tools): the largest leak — a user-triggerable tool loop of up to stepCountIs(20) round-trips, never billed; also reached by every channel @mention of an agent. Returns full ProviderResult from getConfiguredModel and meters response.totalUsage so every round-trip counts. - Memory discovery/integration/compaction: run per active user on memory cron, on the expensive pro/glm-5 tier; discovery fires 3 passes/run. - Zoom extract-action-items and generate-summary: per webhook. Mis-metered ($0) call sites — track the resolved providerResult.modelName instead of the raw stored model (PageSpace tier aliases 'standard'/'pro' and the unpriced default 'glm-4.5-air' all hashed to AI_PRICING.default = $0): - /api/v1/chat/completions (was page.aiModel ?? 'unknown') - page-agents/consult (was agent.aiModel || 'glm-4.5-air'); also switch to result.totalUsage since it is a stepCountIs(100) tool loop - /api/ai/chat (was raw currentModel) Catalog↔pricing drift: - Add 'glm-4.5-air' to AI_PRICING (0.35/1.55, matching z-ai/glm-4.5-air); it was selectable via the glm provider but unpriced, so it metered at $0. Correctly-metered paths (global assistant, pulse generate/cron, workflow executor) already used providerResult.modelName and are unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(billing): lock in metering for ask_agent and glm-4.5-air pricing Regression guards for the leak fixes in this PR: - ai-monitoring: assert PageSpace-tier backend models (glm-4.5-air, glm-4.7, glm-5) all price above $0, and that glm-4.5-air bills at its published rate. Catches future catalog↔pricing drift that would meter at $0. - agent-communication-tools: assert ask_agent bills the requesting user against the resolved model name (glm-5) using totalUsage (all tool-loop round-trips), proving the previously-unmetered path is now metered. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(billing): make AI-usage persistence durable and stop $0 ledger churn Two metering-correctness gaps left open by #1475 (audit-leaks), found in the prepaid AI-credits audit. Both are pure correctness/safety; no billing-policy change. 1. Durability (was fire-and-forget). `trackAIUsage` detached the writeAiUsage -> consumeCredits chain with `.then()` and returned before it settled. Callers `await` trackAIUsage from a stream onFinish / post-response handler, but a serverless freeze could drop the detached promise — losing BOTH the usage log AND the charge. With no aiUsageLogs row, the reconcile cron's orphan sweep has nothing to recover from, so the charge is gone for good. Now the chain is awaited, so the write is durable before the request returns. Still never throws into the AI request. 2. $0 ledger churn. A free/local model — or a tool-only analytics log with no tokens (trackAIToolUsage) — produced amountCents 0, yet consumeCredits still opened a balance transaction, took the row lock, and ran a $0 decrement, writing a misleading "applied/monthly" ledger row per call. In an agent tool loop that serialized N no-op locks on the user's balance row. Now a zero-charge call settles the claimed row as 'skipped' without the balance transaction. The claim row still exists, so the orphan sweep stays idempotent and never re-processes it. Tests: +1 durability test (asserts consume runs before the awaited trackAIUsage resolves, no setTimeout flush) and +1 zero-charge test (no transaction, row marked 'skipped'). credit-consume + ai-monitoring suites: 76 passed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(billing): extend usage-persistence durability to the tool-call path Addresses Codex review (P2) on #1476: trackAIToolUsage called trackAIUsage without returning/awaiting it, so a caller that `await`s trackToolUsage resolved immediately — the durability guarantee didn't reach tool-analytics logs, and the writeAiUsage / zero-charge ledger settlement could still be dropped on a serverless freeze after onFinish. trackAIToolUsage now RETURNS the trackAIUsage promise (no longer an async wrapper that discards it), so awaiting it waits for the log to persist. +1 test asserting the returned promise stays pending until writeAiUsage settles. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(billing): schedule reconcile cron, drain backfill, bill errored-but-real AI spend The "billed exactly once across crashes/deploys" guarantee had three holes: W4a — reconcile cron unscheduled. /api/cron/reconcile-credits existed and was HMAC-protected but absent from docker/cron/crontab, so nothing ever ran the reconciliation. Added a signed GET every 10 minutes using the same cron-curl pattern as the other ~16 jobs. W4b — backfill never drained. backfillCredits() did a single LIMIT 200 pending sweep + single LIMIT 200 orphan sweep; a backlog >200 silently left the rest. It now loops until a pass returns fewer than BATCH from both sweeps (settled rows drop out of the next query, so re-querying makes forward progress), bounded by MAX_PASSES=50 as an unbounded-run backstop. GRACE_MS cutoff and the isBillingEnabled() guard are unchanged; returns cumulative {retried, orphans}. R1 — errored-but-real spend was dropped (deliberate billing-policy change). Tokens consumed before a mid-stream error/abort are real provider cost, but trackAIUsage only billed when success===true and the orphan sweep filtered success=true, so an errored generation that produced tokens was logged with a real cost and billed by neither path. Now: - trackAIUsage bills when aiUsageLogId && (success || totalTokens > 0). A token-less pre-generation failure still carries 0 tokens and is skipped; consumeCredits still settles a zero-charge call as 'skipped' (no $0 churn). - the orphan sweep reconciles success:false rows carrying cost > 0, and now filters gt(cost, 0) so no/zero-cost rows stay excluded. The base PR intentionally left failed calls unbilled; the audit owner has decided errored-but-real spend MUST be billed. Tests: backfill drains a >200 backlog across passes, stops at the safety cap, bills a success:false orphan with cost, and asserts the sweep no longer gates on success; trackAIUsage bills an errored call with tokens but not a token-less failure. @pagespace/lib typecheck clean; billing + ai-monitoring suites green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(billing): fund prepaid balances from Stripe (invoice.paid refill + credit-pack top-up) The pure routing/arithmetic in credit-core (classifyStripeEvent, computeMonthlyRefill, applyTopup) had zero callers and there was no funding shell, so a paid invoice or credit-pack purchase never became spendable credit. The webhook only logged invoice.paid and ignored credit-pack checkouts. Add credit-funding.ts — an imperative shell that: - invoice.paid -> resets the monthly bucket to the tier allowance, rolls the billing window forward from the invoice period, and records a monthly_grant ledger row keyed on the invoice id. - checkout.session.completed (mode=payment, kind=credit_pack) -> adds the pack to the never-expiring top-up bucket via applyTopup, recording a topup_purchase ledger row keyed on the session id. Exactly-once: each funding ledger insert uses onConflictDoNothing against the partial unique index credit_ledger_stripe_ref_unique (predicate restated as the arbiter), and the balance mutation only runs when that insert actually inserted — so a redelivered Stripe event credits the balance exactly once. Ledger insert and balance write share one transaction. Funding never throws into the webhook: a failure is logged and swallowed; Stripe retry / the reconcile cron re-delivers. No-op when billing is disabled (tenant/onprem) and for tier_change events (tier persistence stays in handleSubscriptionChange; the next invoice.paid refills at the new allowance). Wire applyStripeFunding into the webhook for invoice.paid and checkout.session.completed, additively — existing logging and subscription-tier behavior are unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(billing): enforce prepaid gate at AI entry points + log usage when metadata missing Wire canConsumeAI() into every user-facing AI generation entry point so an out-of-credits user is blocked (HTTP 402) before the model runs, instead of the platform silently fronting the overage. Also fix the global-messages route to always write an aiUsageLogs row (R4) so the orphan-sweep can recover/bill calls where the provider returned no usage metadata. Entry points gated (402 out_of_credits when !gate.allowed): - api/ai/chat - api/ai/global/[id]/messages - api/v1/chat/completions - api/ai/page-agents/consult - api/pulse/generate (on-demand; cron path intentionally not gated) R4: api/ai/global/[id]/messages now always calls AIMonitoring.trackUsage in onFinish (0/undefined tokens are fine — $0 cost, but the log row exists). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(billing): make credit-pack top-up funding race-safe; correct funding-failure docs Self-review of the funding shell surfaced a lost-update on the top-up money path: two concurrent first-time credit-pack purchases (distinct session ids, so their ledger inserts don't serialize each other) would both SELECT ... FOR UPDATE on a not-yet-existent balance row — locking nothing — both read 0, and the second write would overwrite the first instead of adding to it, silently dropping a paid top-up. Fix: inside the funding transaction, ensure the balance row exists first (INSERT ... ON CONFLICT DO NOTHING), then SELECT ... FOR UPDATE always locks a real row, making the read-add-write atomic. applyTopup is still the source of the new value; concurrent purchases now serialize on the row lock and both increments apply. Add a first-time-buyer regression test alongside the existing add-to- existing-balance test. Also corrected the module/function docs: funding swallows its own errors (never 500s) and the webhook's coarse stripeEvents guard blocks same-event reprocessing, so a failed funding event is not auto-recovered by Stripe retry. The previous comment overclaimed retry/cron recovery; it now states failures are surfaced via logs for operator follow-up. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(billing): non-zero reserve floor, shortfall-as-debt, sub-cent remainder, gate-driven monthly reset Closes four correctness gaps in the prepaid credit core: R2a — Reserve floor default 0 -> 25¢, bounding the single in-flight call that can overshoot zero (cost is only known post-stream). Env override kept. R2b — Shortfall is no longer silently discarded. decrementAndSettle records appliedCents (what actually left the balance) on the usage row and, when the balance can't cover the charge, writes the uncovered remainder as a terminal 'adjustment' (debt) row in the same txn — visible, queryable by aiUsageLogId, recoverable. Balances stay >= 0 (DB CHECK); debt lives in the ledger. The usage-log unique index is scoped to entryType='usage' so the debt row can share the call's aiUsageLogId. R3 — Sub-cent costs no longer round to $0. Charges accrue in millicents into a per-user pendingMillicents carry; each settle debits floor(pending/1000) whole cents and banks the remainder. New pure core: chargeMillicents / accruePending / accrueCharge. No float ever reaches stored state. W3-free — canConsumeAI now stamps a monthlyPeriod{Start,End} on lazy-init and, when the window has expired, resets the monthly bucket to the tier allowance and rolls the window forward — giving free/no-subscription users a monthly reset without a cron. The reset UPDATE re-checks expiry in its WHERE so a racing invoice.paid refill naturally wins. Schema: + credit_balances.pendingMillicents, + credit_ledger.appliedCents, + credit_ledger.chargeMillicents; usage-log unique index scoped to 'usage'. Migration 0144 generated (not hand-written). Out of scope (tracked separately): per-user in-flight concurrency cap / reservation, which requires threading a reservation id through routes+monitoring. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(billing): mark funding ledger rows settled so the backfill cron can't claw them back Critical: monthly_grant and topup_purchase rows inherited creditLedger's default consumeStatus 'pending'. backfillCredits() sweeps EVERY pending ledger row through settlePendingLedgerRow() -> decrementAndSettle(), which SUBTRACTS abs(amountCents) from the balance (it exists to settle unsettled *usage* charges). A funding row has a positive amountCents, so after the 5-minute grace period the cron would reverse every grant/top-up — clawing back exactly the credit funding just added. Funding applies its balance change in the same transaction as the ledger insert, so the row is already settled the moment it is written. Insert funding rows with consumeStatus 'applied' so the pending sweep skips them. Add assertions to the monthly-refill and top-up tests pinning consumeStatus 'applied'. Reported by Codex review (P1). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(billing): end-to-end credits-flow integration tests Drive the real billing shells (applyStripeFunding, canConsumeAI, consumeCredits, backfillCredits) wired together over one shared in-memory DB, proving the prepaid money path fund→gate→consume→reconcile works as a single system. Covers happy path, idempotency (aiUsageLogId + stripeRef), crash recovery (pending settle, orphan sweep, success:false billing, >BATCH multi-pass drain), monthly reset, sub-cent accrual, shortfall/debt, and billing-disabled no-op. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(billing): align gate tests with #1473 (mock createAdminRestrictedResponse + isAdminOnlyProvider) * fix(billing): await ask_agent metering so the sub-agent charge is durable Addresses Codex P2: trackAIUsage now persists+debits inside its returned promise, so the ask_agent call must await it (matching the chat/v1 handlers) or the sub-agent usage log and credit debit can be dropped on a serverless return. * fix(billing): make funding failures retryable via Stripe redelivery Codex P1 (re-raised): the webhook commits its stripeEvents idempotency marker before processing, so a swallowed funding failure was lost forever — Stripe's redelivery short-circuits as "already processed" and the backfill cron reconciles only usage rows, not funding. A transient DB error during invoice.paid or a credit-pack checkout could leave a paying customer permanently unfunded. applyStripeFunding now logs and RE-THROWS genuine failures (non-actionable cases — billing disabled, ignored events, unknown customer, missing ids — still return quietly). The webhook wraps funding in fundOrLetStripeRetry: on a funding failure it deletes the stripeEvents marker and rethrows, so the route returns 500 and Stripe redelivers, reprocessing the event. Funding is idempotent on creditLedger.stripeRef, so the balance is still credited exactly once. Safe to reprocess: the handlers that run before funding on these events are log-only / no-op (handleInvoicePaid only logs; handleCheckoutCompleted acts only for mode 'subscription', whereas a credit-pack top-up is mode 'payment'). Tests: rethrow-on-failure assertion replaces the old swallow test; added a non-actionable-cases test asserting no throw for unknown customer / ignored / billing-disabled. 55 billing tests pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(lib): export ./billing/credit-funding so the web build can resolve it The Stripe webhook route imports @pagespace/lib/billing/credit-funding, but the new module was missing from package.json exports + typesVersions. tsconfig-path typecheck resolved it locally, but the Next build resolves via package exports and failed collecting /api/stripe/webhook. Verified: web build now exits 0. * fix(billing): make the whole funding-relevant webhook path retryable, not just funding Codex P1: the marker-cleanup only wrapped the funding call, but for invoice.paid handleInvoicePaid runs first and does a DB user lookup. A transient failure THERE threw before the cleanup, leaving the stripeEvents marker in place — the outer catch returns 500, and Stripe's redelivery short-circuits at the marker conflict and never reaches applyStripeFunding, so the paid monthly credit is still lost. Replace fundOrLetStripeRetry(event) with withFundingRetry(eventId, run): it wraps the WHOLE funding-relevant case body (pre-funding handler + applyStripeFunding) and deletes the marker on ANY failure before rethrowing, so Stripe redelivers and the whole path reruns. Safe to reprocess: handleInvoicePaid only logs; handleCheckoutCompleted's sole throwable is an idempotent customer-link upsert (and it acts only for mode 'subscription' — a credit-pack top-up is mode 'payment'; its provisioning POST swallows its own errors); funding is idempotent on stripeRef. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(billing): gate self-heals a NULL monthly period so top-up-first users get the free allowance If a credit-pack purchase creates the first credit_balances row (topup funding inserts { userId } only — monthly 0, monthlyPeriodEnd NULL) before the user's first AI request, the gate previously skipped both the reset (period was NULL, not expired) and lazy-init (a row existed), so the free monthly allowance was never granted and never reset. The gate now resets on (period IS NULL OR expired), stamping a window and granting the tier allowance. Race-safe: the UPDATE re-checks the same predicate. +1 test; integration fake-DB engine gains an 'or' operator. * fix(billing): address CodeRabbit review (gate ordering, paid-user reset, migration CHECK, test rigor) - chat route: run the prepaid gate BEFORE persisting the user message, so a 402 no longer leaves an orphaned/duplicate prompt in chat history on retry. - credit-gate: restrict gate-driven monthly reset to FREE/non-subscription users. Paid tiers refill authoritatively via invoice.paid; gate-resetting them would over-grant when a renewal invoice is late or retried. +tests (paid user blocked). - migration 0144: add the credit_balances_pending_millicents_range CHECK so DBs upgraded through this migration enforce the 0<=pending<1000 carry invariant. - global R4 test: prove trackUsage is AWAITED via a never-resolving deferred (a synchronous mock + 'was called' could not catch a fire-and-forget regression). - integration test: derive the billing window from Date.now() so the funded period is always active (a hardcoded past window let the gate refill mid-test). - consult test: drop the file-wide no-explicit-any disable; type the mock helpers. * fix(billing): bound drain loop on no-progress, not just MAX_PASSES Review hardening for the backfill drain loop: - No-forward-progress break. `decrementAndSettle` (credit-consume.ts) leaves a ledger row 'pending' when the user has no balance row yet, so such rows never drop out of the pending sweep. The drain loop would therefore re-fetch and re-attempt the same unprocessable batch every pass up to MAX_PASSES (50× the work, every 10-min cron run, for a balance-less backlog). Now each pass fingerprints the fetched rows (order-independent); two identical consecutive passes mean nothing settled, so the loop stops instead of churning. A truly stuck full batch now ends in 2 passes, not 50. Partial progress still drains normally via the short-pass break. - Hoisted the cap-exhaustion warning out of the loop body. It now fires exactly when the loop ran to MAX_PASSES (a real remaining backlog), not on a narrow last-iteration batch-size coincidence, and is now covered by tests. Tests: +1 (stuck full batch stops early, no MAX_PASSES warning) and the cap test now asserts the warning fires. @pagespace/lib typecheck clean; full lib suite 178 files / 4361 tests green.

Exported + unit-tested across mid-month, month-end, leap-year, and year-rollover cases. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> (cherry picked from commit 7e69435) * fix(billing): address credits-remediation review findings (gate ordering, funding tier/customer, expired paid monthly, webhook test) Five follow-ups from the /aidd:review of pu/credits-remediation: - [P1] Mock applyStripeFunding in the webhook unit tests. The new funding call loaded the real billing module against a mock db that can't satisfy its query chain, turning every funding-relevant event into a 500. Mock the module and add wiring assertions (funding invoked once per event; 500 is retryable). - [P1] Resolve a credit-pack buyer from trusted session metadata.userId before the customer link. A first-time payment-mode checkout doesn't link the Stripe customer to a user, so the customer lookup missed and the top-up was silently dropped. resolveTopupUser prefers metadata.userId, falls back to the customer. - [P2] Run the global-assistant credit gate BEFORE persisting the user message, matching the page-chat route. A denied request no longer leaves an orphaned prompt that duplicates on top-up + retry. - [P2] Exclude a paid user's expired monthly bucket from the gate decision. Once monthlyPeriodEnd has passed (renewal delayed), leftover monthly allowance no longer funds calls — only the never-expiring top-up does (blocked-until-renewal). - [P2] Base the monthly refill on the tier derived from the PAID invoice line, not the stored users.subscriptionTier, so an invoice.paid that races ahead of the subscription webhook still grants the correct allowance. applyStripeFunding takes an optional { tier }; the webhook derives it via getTierFromPrice. Tests: +4 lib billing (95 pass), +4 web route (webhook/global gate). lib + web typecheck clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(marketing): move pricing/FAQ/terms copy to metered AI credits (#1495) Rewrite every "N AI calls per day" surface in apps/marketing to the prepaid metered AI-credits story: each tier includes a monthly $ AI-credit allowance that meters usage, you can buy more anytime via top-up packs, unused monthly credits reset each billing period, and model access still differs by tier (free = standard models; paid = standard + Pro models). Numbers are sourced from packages/lib billing/credit-pricing.ts via a new single-source-of-truth module (apps/marketing/src/lib/credits.ts) so public copy can't drift from what the app actually meters. Surfaces updated: pricing page (cards + comparison table), FAQ (incl. new "how credits work" entry + reworded out-of-credits answer), Terms (plan list + usage-limits section), getting-started + features/ai docs, privacy, schema.org offers, search index, and the BYOK blog post.

Supports --dry-run, --verified-only, --limit, --delay-ms, --log. Verified end-to-end with --dry-run against a seeded DB: per-tier numbers render correctly (free $5 / pro $15 / founder $50 / business $100), invalid emails skip, ledger entries skip, and --verified-only/--limit behave. No real emails sent. lint, typecheck, build, and lib tests green.

Resolve the URL from NEXT_PUBLIC_APP_URL then WEB_APP_URL, preferring the first non-localhost value (handles a setup where only the server-side WEB_APP_URL is production). - Make the idempotency ledger crash-safe: open + validate writability before the first send, fsync each record, and treat a ledger-write failure after a successful send as fatal — abort and name the unrecorded recipient so a re-run can never silently double-send it. - Drop the unused emailVerified column from the user select.

GateResult gains holdId. - credit-consume: consumeCredits({…, holdId?}) releases the hold inside the settle transaction (and on the zero-charge path); new releaseHold() frees a reservation for token-less failures that never bill. - credit-backfill reconcile: sweeps holds past expiresAt so a crashed stream's reservation can't permanently shrink spendable (BackfillResult.expiredHolds). - holdId threaded gate -> route -> billing: AIUsageData/trackUsage -> consumeCredits, across all 5 AI routes (+ agent-communication-tools note). Shared credit-gate-response helper maps out_of_credits -> 402, too_many_in_flight -> 429. Workstream B — retire daily AI rate limits: - chat + global-assistant routes: removed the getCurrentUsage -> createRateLimitResponse (429) blocks and the incrementUsage/broadcastUsageEvent calls in onFinish. Model-tier gating (requiresProSubscription / admin-only providers) preserved. usage-service / rate-limit-cache / rate_limit_buckets / sweep-expired left intact — confirmed they back auth/login/integration limits. Tests: extended billing unit + integration suites (hold accounting, in-flight cap, hold release on settle, expiry sweep, full gate->consume hold lifecycle) and added route 429 + helper coverage. lib 4426 + web routes green; typecheck, lint, web build all pass.

P2 (global/[id]/messages + chat + consult + pulse routes): release the credit hold on pre-generation early returns/throws. A holdHandedOff flag + finally frees the reservation whenever the request exits after the gate but before the stream/billing takes ownership (auth/permission/provider/save failures), instead of stranding it against the user's balance + in-flight cap until the reconcile sweep. v1 unchanged (no explicit early return after its gate; a throw falls through to the reconcile backstop like any crashed stream).

Gives users the surfaces that make the hard cutover humane: see their balance, get correct 402/429 messages with a CTA, and buy more credits. - Balance API: GET /api/credits → { monthly, topup, spendable, reserved } with a read-only getCreditBalance() that mirrors the gate's window semantics for display (free-tier lapsed → full allowance; paid lapsed → 0 monthly; spendable nets holds). SWR hook useCreditBalance with live socket updates. - Live updates: replace the retired daily-quota usage:updated socket event with credits:updated (broadcastCreditsEvent + emitCreditsUpdated), emitted after a call settles (the two interactive AI routes) and after funding (the Stripe webhook). - Widget: replace UsageCounter with a CreditBalance header widget (remaining + low warning + Buy credits) and a CreditBalanceCard on settings/billing. settings/plan + settings/billing now show credits, not aiCalls/day. - Buy-credits checkout: POST /api/stripe/create-credit-topup mirrors create-subscription (mode:'payment', inline price_data from CREDIT_PACKS, metadata.kind='credit_pack'), so the existing webhook funds the top-up bucket. BuyCreditsButton in settings + in the out-of-credits chat error states. - Error UX: classifyAIError distinguishes out_of_credits (402) and too_many_in_flight (429) with distinct copy; SidebarChatTab + ChatInputArea show a Buy-credits CTA. - Copy: plans.ts limits move from aiCalls/pro/day to a monthly credit allowance + proModels capability, sourced from credit-pricing via a new web credits.ts helper (mirrors apps/marketing/src/lib/credits.ts).

Not changed: CodeRabbit's "decouple apps/marketing from @pagespace/lib" — master already couples it (contact route imports @pagespace/lib/security), so the standalone premise is stale; the import is the no-drift source of truth.

Add an env flag so the gate can be dark-launched: deploy the code in observe-only mode (meter + record real cost/charged credits for the unit-economics view) and flip blocking on deliberately once the numbers are validated. - credit-pricing.ts: envBool + isCreditsEnforcementEnabled() (default FALSE), read at call time so it toggles via env+redeploy and is settable per-test. - credit-gate.ts: the gate still does ALL bookkeeping (lazy-init, monthly reset, balance read, hold on the allow path); when enforcement is OFF it only overrides a would-be denial (out_of_credits / too_many_in_flight) to allowed:'enforcement_disabled'. A credit-having user is unchanged (normal allow + hold). consumeCredits is untouched, so metering/observability run regardless. - credit-core.ts: add 'enforcement_disabled' to GateReason (an allowed reason; credit-gate-response only maps deny reasons, so no HTTP change). - tests: the two suites that exercise real enforcement set CREDITS_ENFORCEMENT_ENABLED=true; new dark-launch cases assert denials are suppressed while bookkeeping still runs.

Summary
Exposes the paid OpenRouter provider to global admins only (gated on
role === 'admin', independent of subscription tier), refreshes the model catalog against the live OpenRouter API, and keeps the metering price table in sync.Admin-only gating (role-based, not tier)
ADMIN_ONLY_PROVIDERS+isAdminOnlyProvider()inai-providers-config.tsas the single source of truth.GET/PATCH /api/ai/settings: provider visibility is now role-aware — admins see & can select paid OpenRouter; everyone else (includingpro/business) gets it masked →503on PATCH. Admins bypass the Pro-subscription gate.requiresProSubscription()gains anisAdminshort-circuit./api/ai/chatenforces admin-only at generation time (defense-in-depth: handles a demoted ex-admin whose stored selection is still paid OpenRouter)./api/ai/settingsreports as available.A paid-tier non-admin gets no access; an admin on the free tier does. Admins still count against the standard/pro daily rate-limit quota.
Catalog refresh (hit the live API — 343 models)
Diffed the static list against the live OpenRouter catalog:
claude-3.5-sonnet,gemini-2.0-pro,grok-4,grok-4-fast,llama-3.1-405b-instruct,devstral-medium/small,gpt-5.2-mini/nano,jamba-mini-1.7,inception/mercury,gemini-2.5-flash-lite-preview-06-17).:free/legacy variants were intentionally excluded (the selector is for tool-using chat).Metering / pricing (the important bit 💸)
calculateCost()falls back todefault: { input: 0, output: 0 }, so any model missing fromAI_PRICINGis metered as free. Added per-1M prices (pulled from the live OpenRouter API) for every newly added model, achieving full catalog↔pricing parity — and fixed a pre-existing gap wherewriter/palmyra-x5was unpriced.Verification
typecheck: clean across all changed source files (after building@pagespace/db+@pagespace/lib).Provider surfaces covered
Both per-user model-selection paths go through the same gated
ProviderModelSelector(chat footer + global assistant viaChatInput → InputFooter), so admins see paid OpenRouter in both and non-admins never do. Backend enforcement (admin-only guard + admin subscription bypass) is applied on both the page-AI chat route (/api/ai/chat) and the per-user global assistant route (/api/ai/global/[id]/messages).Genuinely out of scope: shared page-agent (AI Chat page) configuration used by other drive members — that is a shared surface with different semantics and is not part of this per-user admin-gating change.
