What

Closes #1063 (the surface half; the endpoint it asked for is included).

A signed-in chat user had no way to see credits or usage anywhere. This adds a small pill above the chat composer showing credits remaining and today's spend, with Claude-style phrasing, dismissible for the session.

Data source

The balance is derived, never stored (credit_ledger_entries summed by ledger.Service.GetBalance, reused untouched). The gap #1063 identified was identity: chat sessions authenticate as Open WebUI users in tenant_users, a disjoint id space from account_memberships, so /api/v1/accounts/current/credits/balance is unusable from chat as-is.

New internal route on control-plane:

POST /internal/chat/credits/balance   {"email": "..."}
  -> 200 {posted_credits, reserved_credits, available_credits, usage_today_credits}
  -> 404 no billed account (banner hides)
  -> 400 empty/oversized body

Mounted behind RequireInternalToken, and only when a nonempty internal token is configured. The OWUI backend shim (owui-patches/hive_credits.py) resolves its own signed-in session to an email server side and calls this route with the X-Internal-Token header; the browser only ever sees the trimmed numbers under Open WebUI's own session. tenant_billing_accounts never reaches a browser.

Multi-tenant members resolve to the tenant selected in the product (raw_user_meta_data->>'selected_tenant_id', written by /v1/tenants/switch), newest active membership as fallback; malformed selections degrade to the fallback order.

UI

  • src/lib/hive/CreditsBanner.svelte: three states.
    • healthy/low (below $0.50 in credits): "You've used N credits today · M remaining", amber at low.
    • empty: "You're out of credits." + Top up link when HIVE_CONSOLE_BILLING_URL is configured (deployment configuration served through the shim as top_up_url).
  • Renders above both composer paths (conversation MessageInput and the landing Placeholder).
  • Dismissible for the browsing session (sessionStorage, survives remounts).
  • Any fetch failure degrades to no banner, zero console spam.
  • MessageInput.svelte submit logic untouched.

Enterprise posture

Prepaid credits are a hosted-SaaS concept. Deployments that do not carry CONTROL_PLANE_INTERNAL_TOKEN on the chat container get 404 and no banner (control-plane does not even mount the route); silent absence is the posture gate, documented in compose comments.

Tests

  • Go unit tests (stub repo): resolution, not-found semantics, handler contract incl. method/body/email edge cases, gate wiring.
  • Go live-DB tests (HIVE_TEST_DB_URL-gated, run against the full migrated schema): four-table join, case-insensitive email, selected-tenant-wins, malformed-selection fallback. Verified locally against a migrated throwaway Postgres.
  • Frontend vitest suite (81 tests green): state thresholds, dismissal persistence + storage-absence degradation, fetch success/non-200/network-failure silence, top_up_url passthrough.

Visual proof

Posted below against a stack built from this branch (frontend + control-plane internal route, full migrated schema, signed-in chat user): healthy, low, and empty banner states. Comment: #1119 (comment) ; capture log: docs/proof/usage-at-composer/capture-2026-08-24.md

Review streams

  • CodeRabbit GitHub app: ran (5 findings). All addressed or rebutted; every thread resolved.
  • Plain adversarial pass: ran. Four findings fixed pre-push (dismissal persistence across remounts, payload coercion inside the failure path, server-side upstream-failure logging, i18n) plus one integration bug caught only by the live proof stack (shim sent the shared secret on Authorization: Bearer; RequireInternalToken reads X-Internal-Token): fixed and verified end to end.
  • CodeRabbit CLI: SKIPPED, twice, WebSocket connection error from this environment. Noted per pipeline fallback rules.

Buglog entry

Carried in commit 41d070f (wrong auth header between shim and RequireInternalToken, found by live-stack verification); to be appended to .wolf/buglog.jsonl on main via a buglog-only PR once this merges, per the issue #873 protocol.

Issue #1063: a signed-in chat user had no way to see credits or usage
anywhere. This adds the missing Claude-defining surface: a small pill
above the composer showing credits remaining and today's spend.

Control plane (Go, unit + live-DB tested): new internal route
POST /internal/chat/credits/balance behind RequireInternalToken.
Service.GetChatBalance resolves the signed-in email through auth.users ->
tenant_users -> tenant_billing_accounts and reuses ledger.Service.GetBalance
untouched, plus GetUsageSince for today's usage charges. The tenant-to-
account link never crosses to a browser; unmapped emails are 404, errors
are opaque and never echo the email; the body is size-capped and the
email rides in a POST body so it cannot land in access logs.

Chat backend shim: owui-patches/hive_credits.py mounts GET
/api/v1/hive/credits/balance under get_verified_user, forwarding only the
session-resolved email server side. Deployments without the control-plane
token (Hive Enterprise posture) get 404 and no banner: silent absence is
the posture gate.

Frontend: src/lib/hive/CreditsBanner.svelte renders three states with
Claude-style phrasing (healthy and low: used-today plus remaining;
empty: out-of-credits warning linking to console top-up). Dismissible for
the browsing session via sessionStorage. Every fetch failure degrades to
no banner with zero console noise. MessageInput.svelte submit logic is
untouched; Chat.svelte gains one import and one component mount.

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds tenant chat credit resolution, a token-protected control-plane endpoint, an authenticated Open WebUI proxy route, and a dismissible credits banner above the chat composer.

Changes

Chat credits balance flow

Layer / File(s) Summary
Ledger account resolution and usage queries
apps/control-plane/internal/ledger/repository.go, apps/control-plane/internal/ledger/service_test.go, apps/control-plane/internal/ledger/chat_balance_live_test.go
The repository resolves active billed accounts by normalized email and sums usage from a supplied timestamp. Stubs and live tests cover mapped and unmapped emails.
Protected chat balance API
apps/control-plane/internal/ledger/chat_balance.go, apps/control-plane/cmd/server/main.go, apps/control-plane/internal/ledger/chat_balance_test.go
The service calculates balance and UTC-day usage. The control plane registers a gated POST route with bounded requests, validation, structured responses, and opaque server errors.
Open WebUI backend integration
deploy/docker/owui-patches/hive_credits.py, deploy/docker/owui-patches/apply_credits_patch.py, deploy/docker/Dockerfile.open-webui, deploy/docker/docker-compose.yml
Open WebUI retrieves the signed-in user email, calls the internal control-plane route with a bearer token, and exposes normalized balance data. Docker build steps inject and validate the router.
Chat credits banner
vendor/open-webui/src/lib/hive/credits.ts, vendor/open-webui/src/lib/hive/CreditsBanner.svelte, vendor/open-webui/src/lib/components/chat/Chat.svelte, vendor/open-webui/src/lib/hive/credits.test.ts
The frontend classifies credit states, fetches balances, refreshes on visibility changes, supports session dismissal, and renders the banner above the editable chat composer.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔴 Critical · up to a877d

This PR adds credit and usage visibility to chat, but the balance endpoint currently relies on a committed fallback token that could allow unauthorized balance lookups. It also has unresolved risks of showing the wrong tenant’s balance, inaccurate financial aggregation, misdirected billing links, and missing the banner before the first message; merge should be blocked until the security issue and these correctness issues are addressed.

…server side

Adversarial self-review fixes before review streams:

1. CreditsBanner initialized its dismissed flag to false on every mount,
   so an SPA navigation that remounted the composer resurrected a banner
   the user had dismissed this session. Initialize from sessionStorage
   instead.

2. hive_credits coerced the upstream payload outside the try block, so a
   malformed response surfaced as a 500 traceback instead of the same
   quiet 404 path every other failure takes.

3. Upstream non-200 now leaves exactly one server-side log line with the
   status code and nothing else, so an operator reading container logs
   can tell a down surface from silent absence without the browser ever
   getting console noise.

… top-up URL, landing banner

Review stream findings on PR #1119, addressed:

1. Internal-token fallback (critical): the open-webui compose lines now
   pass CONTROL_PLANE_INTERNAL_TOKEN through with no committed default,
   and control-plane mounts the chat-balance route only when a nonempty
   internal token is configured. RequireInternalToken already fails
   closed; skipping the mount makes misconfiguration read as silent
   absence. The pre-existing hive-local fallback shared by other
   services' env blocks is untouched: changing it here would alter
   unrelated services' local-dev boots and belongs in its own change.

2. Multi-tenant resolution: ResolveAccountIDForEmail now prefers the
   tenant selected in the product (/v1/tenants/switch writes
   raw_user_meta_data->>'selected_tenant_id') over the newest-membership
   fallback, via text comparison so a malformed selection degrades to
   the fallback order instead of erroring. Live regression test covers
   no-selection, selected-wins, and malformed-selection.

3. Landing composer path: CreditsBanner also renders above Placeholder
   for the no-messages landing state, not only above MessageInput.

4. Top-up URL is deployment configuration: the shim serves
   HIVE_CONSOLE_BILLING_URL from its environment as top_up_url; the
   banner renders the link only when configured, warning text either
   way. No hardcoded production host in frontend source.

Also fixes the live test's own seed (tenants.deployment is an enum-like
check constrained to HIVE_CLOUD / ENTERPRISE_EDGE, not 'cloud'), which
is what broke Go tests (control-plane) on CI.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
End-to-end proof-stack verification caught what unit tests could not:
the shim authenticated to control-plane with 'Authorization: Bearer',
while platform/http/internalauth.go compares X-Internal-Token, so every
banner request died as upstream 401 and degraded silently. Send
X-Internal-Token.

Buglog entry (to be appended to .wolf/buglog.jsonl on main via a
buglog-only PR once this merges):

{"error_message":"chat credits banner never rendered; OWUI shim got 401 from control-plane on every call","root_cause":"hive_credits.py sent the shared secret on Authorization: Bearer while RequireInternalToken reads X-Internal-Token; unit tests stub both sides so the contract drift was invisible until a live stack exercised it","fix":"send X-Internal-Token from hive_credits.py; verified end to end against a proof stack","tags":["auth-header-contract","owui-shim","integration"]}

…e is pruned (#1150)

## What this is

Thirty-four captures of the running chat and console, taken 2026-08-23
between 20:25 and 20:48 against the demo box, plus a README describing
them.

They existed only inside an unmerged agent worktree and would have been
destroyed by a prune. Two documents depend on them as evidence, both in
the project vault: the functional Claude-parity audit of 2026-08-24, and
the design similarity scorecard written today,
`session-2026-08-25-claude-similarity-scorecard`. The scorecard reads
the owner's 27 Claude Desktop reference captures for design criteria,
then scores Hive against those criteria surface by surface, citing these
files.

No code changes. `docs/` only.

## Redaction

Every image was reviewed before being added. One carried
credential-shaped content: `27-console-api-keys.png` shows the console's
own masked key strings, which print a fixed prefix, an elision and a
short suffix. Six of the seven rows are revoked and one is active. The
suffix cannot reconstruct a key, but a fragment of a live credential
does not belong in a committed capture, so the entire KEY column was
painted over before the file was added. The column header and every
other column are untouched.

Nothing else in the set contains a token, an authorization code, a
session value, or a URL with a credential in its query string, because
these captures are viewport-only and carry no address bar. `npm run
lint:proof-tokens` passes: `ok (161 files under docs/proof/ scanned)`.

The account address visible in the chat sidebar and console account row
is the shared E2E fixture already documented in `docs/live-test-auth.md`
and in earlier proof directories here. The workspace, owner name and
balances in the console captures are E2E fixture values, not a real
tenant.

## Staleness, recorded on purpose

These are the live state of 2026-08-23. Five pull requests have merged
since and no screenshot here reflects any of them: Projects (#1117), the
Scheduled sidebar row (#1118), the composer credits banner (#1119), the
composer size-failure fix (#1112), and the `/artifacts` index (#1141).
The README says so, and the scorecard scores the verified state
separately from a projection for those five. A fresh capture is required
before claiming any of them looks the way it is supposed to.

## Test plan

- [x] `node tools/lint-no-token-in-proof-captures.mjs` passes, self-test
plus 161 files scanned
- [x] Redaction verified by re-reading the modified region of the image
after the edit
- [x] Every one of the 34 images opened and reviewed for credentials,
tokens, account data and customer data before commit

## Summary

Live verification of every capability DEMO.md claims, against the
actually deployed box (chat-hive, console-hive, api-hive, control-hive),
run today after the 2026-08-25 Cloudflare regional-edge false alarm
cleared. Full capability matrix and methodology in
`docs/proof/demo-readiness-verify-2026-08-25/log.md`.

**Confirmed fixed, DEMO.md corrected (was stale):**
- Artifacts (#1110, fixed by PR #1141): `/artifacts` renders a real
empty-state index today, not the "spins forever" DEMO.md described. No
sidebar entry yet (tracked by #943 item 4, not new).
- In-chat credits (#1063, fixed by PR #1119): a "You've used N credits
today, N remaining" strip sits above the composer, matching the console
Billing balance exactly.

**Confirmed still broken, unchanged:**
- Knowledge nav (#1109): clicking it still does nothing (URL unchanged).
Direct `/knowledge` now answers an honest 404 instead of the
originally-reported silent bounce home, a minor symptom shift, not a
fix.

**Verified today's merges, all landed after this session started:**
- Cache-aware billing (#1157) and Anthropic `cache_control` passthrough
(#1152): shipped and tested, but unexercised live. The catalog has no
Anthropic model today, and a direct `usage_events` query shows zero
cache-bearing requests since deploy.
- Free pool failover (#1155) and the null-content coercion fix (#1169):
no regressions in the trailing 24h of live traffic (zero error-status
`usage_events` rows across 356 requests), though neither fix's specific
trigger recurred live to re-test directly.
- External uptime probe (#1166): confirmed running on its 15-minute
schedule, all green. Added a T-1 checklist note pointing at it, since
today's regional Cloudflare maintenance window is exactly the scenario
it exists to catch.

**Corrected a claim broader than the two named stale items:** the "not
demoable: multi user isolation (#947, #948, #949 family)" line was
itself stale. All three were fixed 2026-08-23 (PRs #960, #1067, #1091,
#1096). One residual, #1056 (two Knowledge by-id/files routes still
short-circuit on `role == admin`), is still open, so the line now says
that precisely instead of citing three closed issues.

## New issues filed

None. Every genuinely broken thing found already has an open tracking
issue (#1109, #1056, #943).

## Verification

- `node tools/lint-no-token-in-proof-captures.mjs` passes against the
new proof log.
- Live session obtained via the standard admin one-time-token mint
(`docs/live-test-auth.md`), read-only against the demo fixture account,
no password touched, no message sent, no key minted, no task submitted.
- Screenshots posted separately to the PR via
`scripts/post-pr-visual-proof.sh` (permanent GitHub Release, per
`.wolf/decisions.md` D-042).

## Test plan

- [x] `node tools/lint-no-token-in-proof-captures.mjs`
- [x] Manual read of the rendered DEMO.md for internal consistency
