Keys (was API Keys) and Ingestion.

  • Keys: one table for the ingest key pair, API keys and MCP keys (type filter, status, search), fitted to the content column with container-query lanes. Ingest keys roll only; members can create MCP keys and revoke their own. OAuth clients point to MCP > Connected clients. API reference collapsed.
  • Ingestion: endpoint plus a link to Keys, setup collapses once telemetry arrives, recommendations wrap, mappings with a wide Rule column and an always-visible menu.

Trace sampling was dropped from this stack: ingest is being reworked separately, so there is no sampling endpoint, service or UI here.

Verification

  • keys-table tests, v2 config resource route tests, scoped typecheck of web, api, domain and backend.
  • Local stack: created an API key through the dialog.

Keys

Stack

Settings redesign, bottom to top: #1525 foundation, #1526 general and members, #1527 billing and usage, #1528 keys and ingestion, #1529 audit log, setup health and data platform, #1530 MCP, #1531 AI and email preferences. Bug fixes from the same audit shipped in #1524. Alerts routing is a later stack.

🤖 Generated with Claude Code

One table with type and status filters, ingest keys with reveal, copy and roll, a split create button for API and MCP keys, an OAuth pointer to MCP and a compact API reference.
…ings

Ingest keys move to Keys, setup folds into one row once telemetry arrives, recommendations wrap, and mapping rows get an Applies to column and an always-visible menu.
Keep percentage and slow-span threshold save through the save bar, the error-span switch saves on its own, and the trace_sampling scope family joins the key dialog and API reference.
…eway does

A stored ratio of 0 or a non-positive slow threshold made GET and PATCH fail
schema validation, so the policy could not be repaired from the UI.
…elds

The upsert's conflict branch now sets only the requested fields, inside a
transaction that locks the row so the audit diff reads a consistent before.
Admins always get the ingest pair, so the full-panel error never showed for
them. A failed API and MCP key list now gets an inline alert with retry.
The name lane had no w-0, so long names set the table's width and pushed
Last used and Expires off screen. Lanes now collapse on the table's own
width, the type badge rides beside the name, and the lanes are tighter.
…ert races

With no row, FOR UPDATE locks nothing. The first insert now skips on conflict and
re-reads the other writer's row under lock, so the audit before is its values.

📝 Walkthrough

The change adds organization-level trace-sampling policy retrieval and updates through the v2 API, with persistence and settings controls. It also combines API, MCP, and ingest-key management in settings and revises attribute-mapping and recommendation displays.

Changes: Trace Sampling Policy

Layer / File(s) Summary
Trace-sampling contracts
packages/domain/src/http/trace-sampling.ts, packages/domain/src/http/v2/trace-sampling.ts, packages/domain/src/http/v2/api.ts, packages/domain/src/http/v2/openapi.test.ts
Defines policy and update schemas, defaults, validation, and the GET and PATCH endpoints for /v2/trace_sampling. Registers the API group and adds route-surface expectations.
Policy persistence
packages/backend/src/services/org/TraceSamplingPolicyService.ts, packages/backend/src/services/org/TraceSamplingPolicyService.test.ts, packages/backend/src/services/audit/audit-actions.ts
Adds policy reads and partial updates, normalizes stored values, handles concurrent writes, and declares the trace_sampling.updated audit action.

Connects the routes to the policy service, requires admin access for updates, records changed values, and tests defaults, validation, permissions, scopes, and audit changes. Documents the resource and adds an OpenAPI tag.
Sampling settings interface
apps/web/src/components/settings/sampling-draft.ts, apps/web/src/components/settings/sampling-section.tsx, apps/web/src/components/settings/sampling-draft.test.ts
Adds policy-to-draft conversion, input validation, changed-field patches, admin editing, read-only values, and tests for draft behavior.
Ingestion endpoint and service setup
apps/web/src/components/settings/ingestion-section.tsx, apps/web/src/components/ingest/guided-setup.tsx, apps/web/src/components/settings/settings-section.tsx
Updates the endpoint display and setup instructions, composes sampling controls into ingestion settings, and adds a framework icon strip and section-anchor support.

Key Management and Ingestion Setup

Layer / File(s) Summary
Key row data and filtering
apps/web/src/components/settings/keys-table.ts, apps/web/src/components/settings/keys-table.test.ts
Adds shared row construction, status and type filters, ordering, access summaries, load-failure display rules, and related tests.
Combined key management interface
apps/web/src/components/settings/api-keys-section.tsx, apps/web/src/components/settings/ingest-key-value.tsx, apps/web/src/components/settings/api-reference.tsx, apps/web/src/components/settings/create-api-key-dialog.tsx, apps/web/src/components/settings/api-key-status.test.ts
Replaces the API-only page with a combined API, MCP, and ingest-key view. Adds role-based key actions, ingest-key reveal and copy behavior, API scope documentation, and the trace_sampling scope family.

Mapping Settings Presentation

Layer / File(s) Summary
Mapping and recommendation rows
apps/web/src/components/settings/attribute-mappings-section.tsx, apps/web/src/components/settings/recommended-mappings-section.tsx
Changes mapping labels and admin controls. Recommendation rows now show usage details and distinguish available actions for rename recommendations and other open recommendations.

Maple review

🟡 Confidence 6/10 · needs attention
The service and its concurrency tests check out, but the settings save sends both sampling fields, which undoes a concurrent change to the other one.
quality 88/100 · 1 warning · 1 note · tests covered · risk medium · 2/2 new units observable · 1 file not read

Adds one Keys table for ingest, API and MCP credentials, reshapes Ingestion, and adds GET/PATCH /v2/trace_sampling over the gateway policy row. Backend service, route and scope tests all read; the settings save undermines the partial update. Not read: the generated apps/ios/.../openapi.json.

  • buildKeyRows/filterKeyRows merge the ingest pair, API and MCP keys into one filterable table
  • New GET/PATCH /v2/trace_sampling with admin-only writes and an audit entry
  • TraceSamplingPolicyService.update locks the row and writes only the fields the request names
  • New Sampling section in Ingestion with a percent and millisecond draft

Findings

🟠 Warning · F1 · Sampling save writes both typed fields, reverting a concurrent change

correctness · apps/web/src/components/settings/sampling-section.tsx:44

validateSamplingDraft always builds a payload carrying both trace_sample_ratio and always_keep_slow_spans_ms (sampling-draft.ts:58-64), and TraceSamplingPolicyService.update writes every field the request names. With the page open, a change to only the slow threshold made by another admin or an API key is silently reverted to the value this form last read when this admin edits only the percentage and saves; the audit entry then reports a field this user never touched.

Build the payload from the fields that differ from `saved` (the `samplingDraftFromPolicy(policy)` view of the current policy) instead of sending the whole draft, the way `setKeepErrors` already sends only its own field.

🟢 Confidence 8/10 · likely safe to merge
The samplingPatch fix is pinned by sampling-draft.test.ts; the one open item is the *-scoped Access cell in keyAccessSummary.
quality 98/100 · 1 note · tests covered · risk medium · 2/2 new units observable

Adds an admin-writable GET/PATCH /v2/trace_sampling over the existing gateway policy table, plus rebuilt Keys and Ingestion settings. The previously reported sampling-revert defect is fixed and pinned by tests; the *-scoped Access cell is still open.

  • GET/PATCH /v2/trace_sampling merges partial updates under a row lock
  • samplingPatch sends only the fields the user changed
  • keys-table merges ingest and API/MCP keys into one filtered table
  • Ingestion install steps collapse once telemetry arrives

Still open from earlier reviews

Sampling patch and the first-insert race are pinned by real tests; the one open finding here is unchanged, and the six files "changed since the last review" are not part of this diff.
quality 98/100 · 1 note · tests covered · risk medium · 2/2 new units observable

Merges ingest, API and MCP keys into one filterable Keys table, reshapes the Ingestion tab around the endpoint and a new Sampling section, and adds admin-only GET/PATCH /v2/trace_sampling over the existing gateway policy row. Safe to merge.

  • buildKeyRows/filterKeyRows drive one Keys table with type and status filters
  • TraceSamplingPolicyService.update locks the row and writes only the named fields

Adds a v2 trace-sampling API (admin-only PATCH, audited, clamped reads) and reshapes Settings: one Keys table for ingest, API and MCP keys, plus sampling controls in Ingestion. No new defect in the files changed since the last review; the earlier empty-Access-cell finding still reproduces.

🟢 Confidence 7/10 · likely safe to merge
Service, route and keys-table logic are pinned by tests and I traced the gateway's own clamping; the three reshaped mapping/guided-setup files went unread.
quality 90/100 · 5 notes · tests covered · risk medium · 3/3 new units observable

Adds a v2 trace sampling policy API (admin-only writes, scoped, audited) over the existing gateway policy table, merges ingest, API and MCP keys into one filtered Keys table, and reshapes Ingestion. Safe to merge; the open *-scoped Access cell and the new findings are minor.

  • GET/PATCH /v2/trace_sampling in apps/api, trace_sampling scope, admin-only writes with an audit entry
  • TraceSamplingPolicyService merges partial PATCHes under a row lock, clamping stored rows the way the gateway does
  • buildKeyRows/filterKeyRows put ingest, API and MCP keys in one table with type and status counts
  • Ingestion collapses AddServiceSection once telemetry arrives and hosts the new Sampling section

Findings

🔵 Note · F3 · storedSlowSpansMs reads a stored 0 as off while the gateway keeps every span

correctness · packages/backend/src/services/org/TraceSamplingPolicyService.ts:30

The column is an int4 with no CHECK and this helper exists to render out-of-range rows, so a row holding 0 is reported to the admin as the slow-span rule being off. The gateway reads that same row as Some(0) (apps/ingest/src/main.rs:6945) and then keeps every span whose duration_ms >= 0 (apps/ingest/src/telemetry.rs:4056-4061); only negatives fail u64::try_from and disable the rule. Map negatives to null and leave 0 as a value.

const storedSlowSpansMs = (ms: number | null) => (ms === null || ms < 0 ? null : ms)
🔵 Note · F4 · Ingest chip is offered while the ingest keys are loading or in a status that can never hold them

correctness · apps/web/src/components/settings/api-keys-section.tsx:210

The chip is gated only on ingest !== null, which is true for every admin, so it reads Ingest · 0 while the pair is still loading or has failed, and in the Expired and Revoked statuses (ingest rows are hard-coded active, keys-table.ts:106). Selecting it lands the table on "No keys here / There are no expired keys of this type." with nothing but the other chips to get back.

Gate the chip on rows that exist, e.g. `.filter((type) => type !== "ingest" || ingest?.keys != null)`, or hide it whenever `statusFilter !== "active"` since ingest keys are always active.

0.07000000000000001 and 0.07 are the same double in JS (checked with node -e "console.log(0.07000000000000001 === 0.07)" → true), and both sides of the comparison go through ratioToPercent, so the case stays green even with toPrecision(6) deleted; it repeats the "edit only reformatted" case above it. Use a stored ratio that is genuinely a different double from the payload's.

Store `0.1 * 0.7` (`0.7000000000000001`) and patch with `0.7`, so the noise path is actually taken.

`storedSlowSpansMs` reads a stored `0` as off while the gateway keeps every span
The column is an int4 with no CHECK and this helper exists to render out-of-range rows, so a row holding `0` is reported to the admin as the slow-span rule being off. The gateway reads that same row as `Some(0)` (`apps/ingest/src/main.rs:6945`) and then keeps every span whose `duration_ms >= 0` (`apps/ingest/src/telemetry.rs:4056-4061`); only negatives fail `u64::try_from` and disable the rule. Map negatives to `null` and leave `0` as a value.
Replace those lines with:
const storedSlowSpansMs = (ms: number | null) => (ms === null || ms < 0 ? null : ms)

`Ingest` chip is offered while the ingest keys are loading or in a status that can never hold them
The chip is gated only on `ingest !== null`, which is true for every admin, so it reads `Ingest · 0` while the pair is still loading or has failed, and in the Expired and Revoked statuses (ingest rows are hard-coded `active`, `keys-table.ts:106`). Selecting it lands the table on "No keys here / There are no expired keys of this type." with nothing but the other chips to get back.
Suggested fix: Gate the chip on rows that exist, e.g. `.filter((type) => type !== "ingest" || ingest?.keys != null)`, or hide it whenever `statusFilter !== "active"` since ingest keys are always active.

🟡 Confidence 6/10 · needs attention
Every open finding still reproduces here (ran the float-noise case; read the gateway's ms >= 0 rule), and the delta since the last review is a base merge.
quality 90/100 · 5 notes · tests partial · risk high

Adds the trace-sampling v2 API and one merged Keys table. All five earlier findings still reproduce at this head; the only delta since the last review is a base-branch merge of spend-chart.tsx, which this PR does not contain.

Ingest is being reworked separately, so this stack no longer adds the sampling endpoint, service or UI.

🟢 Confidence 8/10 · likely safe to merge
Two prior info findings, unchanged in the head, cap it; the sampling reverts are complete and leave no dangling reference.
quality 96/100 · 2 notes · tests partial · risk low

At this head the pull request is only the Keys and Ingestion settings rework — one filterable keys table, a reshaped Ingestion tab. The trace sampling API and Sampling section the title and description promise were reverted and no longer exist, so nothing sampling-related ships here.

  • buildKeyRows/filterKeyRows merge the ingest pair, API and MCP keys into one searchable, type- and status-filtered table
  • Members get Create MCP key and a read-only On/Off column; AdminOnlyNotice replaces the old per-section footers
  • Ingestion drops its inline key rows for an EndpointSection that links to the Keys tab
  • Attribute mappings and recommendations lose their tooltips in favour of an always-visible RowActionsMenu
