fix: bound the API key nickname, neutralise CSV formula cells, and name keys on the spend tab

[sakibsadmanshajib]

Fixes #1400
Fixes #1401
Fixes #1403
Fixes #1406

Four of the console defects the 2026-08-29 QA walk found, plus a verdict on a fifth and two items split out with reasons.

#1400, API key nickname

Two separable halves, both here, because the deployed box already carries at least one row with a 5000-character nickname and a cap alone would not repair it.

Going forward. MaxNicknameLen bounds the nickname at 100 characters, counted in runes so a Bangla name gets the same allowance as an English one. 100 is the bound the BYOK label already uses rather than a number invented for this change. Enforcement is in the control plane, since the form is not the only caller. handleCreateKey and handleRotateKey each carried their own copy of the same decode block, and both copies were missing the same two checks, so the block moves into one decodeMintBody they share.

For rows already stored. The name cell bounds its own width and elides, with the full value on the element's title. That is what makes an existing bad row harmless without a database write, and it is why the fix is not only server side.

The same shared decode now refuses an expires_at that has already passed, which used to mint a credential the console listed as Expired on the spot. handleUpdatePolicy is deliberately left alone: setting a past expiry there is a plausible way to expire an existing key, and it mints nothing.

The issue's third observation, that markup in a nickname is stored raw, needed no separate change. It is escaped correctly on render, and the export path it reached is #1401 below.

#1401, CSV formula injection

The two exports had no shared writer, and each hand-rolled join had its own bug. The logs export replaced quotes, commas and newlines with spaces, which destroyed the value it was meant to export while letting a leading = through untouched. The ledger export stripped commas from one column and escaped nothing else.

Both now go through apps/web-console/lib/csv.ts, which neutralises a cell whose first character is =, +, -, @, a tab or a carriage return, then quotes and doubles embedded quotes per RFC 4180.

A plain number is exempt from the neutralisation. Every debit in the billing ledger starts with a minus sign, and blanket-prefixing turns a numeric column into text and breaks SUM in the spreadsheet the export exists to feed. -1+1 is not a plain number and is still neutralised.

Covered: the request logs export (/console/logs) and the billing ledger export (/console/billing?tab=ledger), the two the issue names, and every future console export that uses the shared writer.

Found and not covered: Open WebUI's own admin exports on the chat surface have the same gap. vendor/open-webui/src/lib/components/admin/Settings/Database.svelte (exportUsers) quotes every cell but does not neutralise a leading formula character on a user's name or email, and admin/Evaluations/Feedbacks.svelte (feedbacksToCsv) quotes only on a comma, quote or newline. Both are admin-only and on a different image, so they are reported rather than folded in here.

#1403, spend by API key showed raw UUIDs

The id to nickname join existed in exactly one place, inside the Overview tile's derivation. It now lives in lib/analytics/api-key-labels.ts and both surfaces call it, so the Usage, Spend and Errors tabs resolve a key the same way the tile does, in the table and on the chart axis alike. The unattributed bucket keeps its own label, since that bucket also holds traffic that never carried a key.

The masked tail travels beside the nickname because two keys may share a nickname and the tail is what tells them apart.

When the key list itself cannot be read the raw id stays on screen. Labelling every row Deleted key because a lookup failed would be a fabricated answer, and there is a test for that specific case.

#1406, analytics scrolling sideways

A grid item's default min-width is auto, which is its min-content width, so one card whose row will not wrap sizes the whole auto track past the container and every sibling card stretches to match. [&>*]:min-w-0 on both analytics grids removes that contribution. This is the same reasoning already written down in components/ui/data-table.tsx for tables, which is where the issue pointed.

<main> in console-frame.tsx is deliberately untouched. It is already a flex item of a column that carries min-w-0, and the measurements in the capture log show the grid track was the whole cause here. Widening the treatment to every console route is #525's scope, not this change's.

#1408 item 1, the blended price subtitle

161,794,930,349.395 credits becomes 161,794,930,349 credits per 1M tokens. The three decimal places came from Intl.NumberFormat's default, reached through the generic formatNumber rather than the integer formatter the rest of the product's credits use.

#1402, verified rather than fixed

Not a defect. The screenshot filed with that issue, docs/proof/qa-matrix-2026-08-29/03-console-feature-gates-stuck-saving.png, shows all twenty-five rows rendering their real toggles in their real positions. No Saving… is visible anywhere in it.

feature-gate-manager.tsx keeps a Saving… span in the DOM on every row at opacity-0 with aria-hidden="true", so the row does not jump in width when a real save starts. rowStatus is idle from first paint and only becomes saving inside toggle(). A text scrape that walks textContent or innerText sees that node, because opacity is not visibility. That is what the issue's text dump recorded.

PR #1394 did not fix it either. That change addressed Viewer.TenantID resolution, whose failure mode on this page is the Could not load feature gates empty state, not Saving…. Detail is in the capture log; the issue can be closed on this evidence.

Split out, with reasons

#1405, chat upload limits. Not in this change, and not because of its size. /api/v1/files/ is served by the vendored Open WebUI Python backend, which arrives as the pinned upstream image and is modified through the build-time patch runners in deploy/docker/owui-patches/. Upstream already has the knobs: RAG_FILE_MAX_SIZE is enforced at routers/files.py, RAG_ALLOWED_FILE_EXTENSIONS is enforced there too but only when the list is non-empty, and /api/config publishes file.max_size to the composer, whose existing client-side guard then fires before the request is made. What is missing is the wiring: docker-compose.yml sets RAG_FILE_MAX_SIZE: ${RAG_FILE_MAX_SIZE:-}, an empty default, and does not mention the other two at all.

The trap, and the reason this is not a two-line change to make blind: owui-patches/hive_rag_env_config.py's RAG_CONFIG_ENV reconcile map does not include rag.file.max_size, rag.file.max_count or rag.file.allowed_extensions. Open WebUI's database wins over the environment after a container's first boot, which is exactly what issue #722 documents, so setting the variable on the already-booted demo box would be a silent no-op unless those keys are added to that map at the same time. Getting either half wrong ships a cap that either does nothing or refuses the owner's demo file mid-walkthrough, on a box this repository auto-deploys to on merge, and there is no substrate here to tell those two outcomes apart: the chat stack cannot start locally (issue #1254). Full findings are on the issue.

#1408 item 2, console 404s rendering outside the shell. Not changed, on purpose. app/not-found.tsx's own comment records that this is the access-control boundary for /console/providers, /console/feature-gates and /console/marketplace, which call notFound() server side for a viewer who may not see them (the #947, #948, #949 family). Adding app/console/not-found.tsx would render ConsoleShell for those denials as well, since the boundary cannot tell a denied route from an absent one. That trades a cosmetic inconsistency for a real disclosure. Reported on the issue as a rebuttal rather than implemented.

Verification

• docker compose run --no-deps --build web-console npm run test:unit: 1013 passed. One pre-existing unrelated failure, tests/unit/ci-web-e2e-secret-free.test.ts, which reads .github/workflows/ci.yml, a path the web-console image does not carry. It fails identically on origin/main in this container.
• docker compose run --no-deps --build web-console npm run test:unit -- components/billing: 9 files, 58 tests passed. Scoped run for the billing ledger export this change touches, including the two assertions on the exported bytes (export triggers a ledger-export.csv download whose content is the rendered rows, neutralises a formula-leading idempotency key so a spreadsheet shows text).
• docker compose run --no-deps --build web-console npm run test:unit -- lib/csv: 9 tests passed, covering the shared writer both billing and logs now use.
• docker compose run --no-deps --build web-console npm run build: compiled successfully.
• go test ./apps/control-plane/internal/apikeys/... ./apps/control-plane/internal/usage/... -count=1 -short: ok.
• node tools/lint-no-token-in-proof-captures.mjs: ok, 218 files under docs/proof/ scanned, self-test 16 assertions.
• Every test in this change was watched fail first. analytics-overview-section.test.tsx in particular was re-run with the fix removed to confirm it goes red, and the assertion it failed on is recorded in the capture log's method section.

Visual proof, with the measured before and after numbers, is in docs/proof/console-qa-defect-cluster-2026-08-29/capture-log.md and posted below as release assets.

📝 Walkthrough

Walkthrough

The change adds shared API key validation, readable analytics group labels, bounded analytics layouts, corrected blended-price text, and centralized CSV escaping. Tests cover validation boundaries, rendering, exports, and QA evidence.

Changes

Console and API key behavior

Layer / File(s)	Summary
API key mint validation apps/control-plane/internal/apikeys/http.go, apps/control-plane/internal/apikeys/types.go, apps/control-plane/internal/apikeys/mint_validation_test.go	Create and rotate requests share nickname and expiration validation. Nicknames are trimmed, required, and limited to 100 UTF-8 characters. Expirations must be future RFC3339 timestamps.
Console key form and list bounds apps/web-console/lib/api-keys.ts, apps/web-console/components/api-keys/*	The create form mirrors the 100-character limit, trims submitted names, validates future dates, and prevents long names from widening the list.
Analytics key label resolution apps/web-console/lib/analytics/api-key-labels.ts, apps/web-console/lib/analytics/api-key-labels.test.ts, apps/web-console/lib/analytics/cache-metrics.ts, apps/web-console/lib/analytics/overview-fetch.ts	Shared helpers resolve API key nicknames, masked suffixes, unattributed groups, and deleted keys. Group-key metadata is fetched only for API key grouping.
Analytics page group labels apps/web-console/app/console/analytics/page.tsx, apps/web-console/__tests__/analytics-api-key-group-labels.test.tsx	Usage, spend, and error rows use formatted API key labels when metadata is available. Failed key-list requests preserve the raw group key.
Analytics display formatting apps/web-console/components/analytics/*	Blended-price notes use whole credits per 1M tokens. Analytics grids constrain child widths with [&>*]:min-w-0.
Shared CSV export serialization apps/web-console/lib/csv.ts, apps/web-console/components/logs/usage-logs-csv.tsx, apps/web-console/components/billing/ledger-csv-export.tsx, related tests	CSV exports use RFC 4180 quoting and neutralize formula-leading cells. Commas and supported numeric values retain their intended representation.
QA capture record docs/proof/console-qa-defect-cluster-2026-08-29/capture-log.md	The capture log records the test method and observed results for the API key, CSV, analytics, layout, blended-price, and no-code-change findings.

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

Merge Risk: 🔵 Low · up to 8b1c1

The PR improves API-key bounds, CSV formula safety, analytics labels, and console layout. It is mergeable with owner awareness that a near-future key expiry can lapse before persistence, strict CSV consumers may expect CRLF line endings, and billing-focused test evidence plus proof-document lint cleanup should be completed.

Review stream 1 of 2: CodeRabbit CLI

coderabbit review --agent --committed --base main. Ran and completed. The repository's own CodeRabbit GitHub App check reports Review rate limited on this pull request, so the CLI is the stream that actually produced findings here.

All 25 changed files were reviewed. One finding, severity minor.

Finding, minor: docs/proof/console-qa-defect-cluster-2026-08-29/capture-log.md, the #1402 verdict

Qualify the #1402 verdict to distinguish DOM presence from visual rendering: the statement that the reported symptom never existed should note that Saving… was present in the DOM and in text output but not visually visible in the browser, preserving the distinction needed for triage.

Accepted. The sentence as written ("the reported symptom, as rendered, never existed") leans on "as rendered" to carry the whole distinction, and a reader triaging this later should not have to notice that qualifier to get the right mental model. The node genuinely is in the DOM on every row, and the accessibility tree genuinely excludes it, and both facts matter to anyone deciding whether a future scrape result is a real defect. Reworded in the follow-up commit.

No other findings. Nothing raised on the CSV escaping, the Go validation, or the analytics changes.

Review stream 2 of 2: Antigravity, gemini-3.1-pro-high, effort high

Run with the whole diff pasted inline, since agy executes in its own scratch directory and cannot read this worktree. The reply opened with apps/control-plane/internal/apikeys/http.go and a quoted line from the first hunk, which is this diff, so the review is of the right change.

Five findings. Three accepted and fixed, one accepted and fixed, one rebutted.

---

1. High, accepted and fixed: formula-lead check anchored at index 0 is bypassable

If an attacker sets an API key nickname to \n=cmd|'/c calc'!A0 or =1+1 (with a leading space), the regex fails to match. Excel ignores leading whitespace and newlines, meaning it will still evaluate the DDE payload.

Fixed. FORMULA_LEAD is now /^\s*[=+\-@\t\r]/, so leading whitespace is skipped before the first character is tested. JavaScript's \s already covers the byte order mark and a non-breaking space alongside the ASCII whitespace, and it still matches a tab or carriage return in first position, which remain leading characters worth neutralising in their own right. Five payload shapes are pinned in lib/csv.test.ts.

Whether a given spreadsheet actually trims before evaluating varies by product and by import path, and I did not verify each one. That is the point: a check anchored at index 0 requires the reader to be sure about all of them, and skipping whitespace costs nothing.

One part not taken. The suggested regex also added the fullwidth look-alikes ＝＋－＠ (U+FF1D and siblings). I could not confirm that any spreadsheet evaluates those as formula introducers, and they are ordinary characters in CJK text. Adding them would prefix an apostrophe onto legitimate values while preventing nothing I can demonstrate. If someone can show a product that evaluates U+FF1D, adding them is a one-character change to the class.

2. Medium, accepted and fixed: the numeric exemption was applied to text columns

If a user sets their API key nickname to -001 or +1337 the PLAIN_NUMBER check passes. Excel will interpret these text fields as numbers, dropping the leading zeros. When the file is round-tripped the original string data is permanently corrupted.

Correct, and the underlying mistake is the one the finding names: the exemption is a property of the column, and I had implemented it as a property of the value by sniffing the string with a regular expression.

Fixed by making the exemption travel as a type instead. CsvValue is string | number. A number is stringified and never neutralised; a string is always neutralised if it leads with a formula character, whatever it looks like. PLAIN_NUMBER is deleted, and both call sites now pass their counts and deltas as numbers rather than pre-stringifying them. This is a smaller change than threading a column type through, and it makes the intent unforgeable: attacker text arrives as a string by construction.

csvCell(-2000)   "-2000"    numeric column, still sums
csvCell("-001")  "'-001"    text column, value preserved exactly

3. Medium, rebutted: "Deleted key" cannot mislabel a live key here

If that endpoint paginates its results, any active key with spend that falls outside that first page will not be present in keyById. The UI will incorrectly fabricate a label of "Deleted key" for a perfectly live key.

The premise does not hold for this repository, and the conditional in the finding ("if getApiKeys() paginates") is doing the load-bearing work. pgxRepository.ListKeys (apps/control-plane/internal/apikeys/repository.go:102) is:

SELECT ... FROM public.api_keys WHERE account_id = $1 ORDER BY created_at DESC

No LIMIT, no OFFSET, no cursor, no status filter. Every key on the account comes back, revoked and expired included. That is already recorded at lib/analytics/overview-fetch.ts:190 as the reasoning behind issue #1347's fix, which is where this label text came from: the only ways a spend row's key id has no match are the unattributed bucket (matched before the lookup and labelled separately), a key genuinely deleted under ON DELETE SET NULL, or a failed fetch, and the failed fetch is handled separately by leaving the raw id on screen.

A staleness window between a key being created and the two concurrent fetches resolving is real but not new, and it is bounded by one request. Renaming the label to "Unknown key" would make the common case (a genuinely deleted key) vaguer in order to hedge a case the schema rules out. Not changed. This label is also unchanged by this pull request; it moved from cache-metrics.ts into the shared helper verbatim.

4. Low, accepted and fixed: an assertion that could not fail

expect(note).not.toContain("0 credits per 1M tokens") will silently pass if the function starts returning "null credits per 1M tokens" or undefined.

Correct, and this repository treats that shape as a defect in its own right (#797). Replaced with an exact-match assertion on "No blended price for this window.".

5. Accepted, resolved by fix 2: the comment claimed more than the code did

The PLAIN_NUMBER comment framed the exemption as being for the ledger's numeric values while the code applied it to every column. The exemption is now genuinely per column, and the comment says so.
