Creates a new table `ai_seat_state` to keep track of when users consume an ai_seat. Once a user consumes an AI seat, they will forever in this table (as it stands today).
Adds the `head_branch` field (the source/feature branch name of a PR) to
the diff status pipeline. Previously only `base_branch` (target branch)
and the head commit SHA were captured from the GitHub API, but not the
head branch name itself.
## Changes
- **Migration 438**: Add `head_branch` nullable TEXT column to
`chat_diff_statuses`
- **gitprovider**: Parse `head.ref` from the GitHub API response
(alongside `head.sha`) and add `HeadBranch` to `PRStatus`
- **gitsync**: Wire `HeadBranch` through `refreshOne()` into the DB
upsert params
- **worker**: Map `HeadBranch` in `chatDiffStatusFromRow()`
- **coderd**: Convert `HeadBranch` in `convertChatDiffStatus()`
- **codersdk**: Expose as `head_branch` (`*string`, omitempty) in
`ChatDiffStatus` API response
- **Tests**: Updated `github_test.go` pull JSON fixtures and assertions
Implement the backend for the desktop feature for agents.
- Adds a new `/api/experimental/chats/$id/desktop` endpoint to coderd
which exposes a VNC stream from a
[portabledesktop](https://github.com/coder/portabledesktop) process
running inside the workspace
- Adds a new `spawn_computer_use_agent` tool to chatd, which spawns a
subagent that has access to the `computer` tool which lets it interact
with the `portabledesktop` process running inside the workspace
- Adds the plumbing to make the above possible
There's a follow up frontend PR here:
https://github.com/coder/coder/pull/23006
Add cost tracking for LLM chat interactions with microdollar precision.
## Changes
- Add `chatcost` package for per-message cost calculation using
`shopspring/decimal` for intermediate arithmetic
- **Ceil rounding policy**: fractional micros round UP to next whole
micro (applied once after summing all components)
- Database migration: `total_cost_micros` BIGINT column with historical
backfill and `created_at` index
- API endpoints: per-user cost summary and admin rollup under
`/api/experimental/chats/cost/`
- SDK types: `ChatCostSummary`, `ChatCostModelBreakdown`,
`ChatCostUserRollup`
- Fix `modeloptionsgen` to handle `decimal.Decimal` as opaque numeric
type
- Update frontend pricing test fixtures for string decimal types
## Design decisions
- `NULL` = unpriced (no matching model config), `0` = free
- Reasoning tokens included in output tokens (no double-counting)
- Integer microdollars (BIGINT) for storage and API responses
- Price config uses `decimal.Decimal` for exact parsing; totals use
`int64`
Frontend: #23037
Migration 000434 converts chat_messages.role from text to a Postgres
enum, rebuilds the partial index, and adds content_version smallint.
The column is backfilled with DEFAULT 0, then the default is dropped
so future inserts must set it explicitly.
Version 0 uses the role-aware heuristic from #22958. Version 1 (all
new inserts) stores []ChatMessagePart JSON for all roles, including
system messages. ParseContent takes database.ChatMessage directly
and dispatches on version internally. Unknown versions error.
All string(codersdk.ChatMessageRole*) casts at DB write sites are
replaced with database.ChatMessageRole* constants from sqlc.
Refs #22958
Adds `pull_request_title` and `pull_request_draft` to the chat diff
status pipeline (DB → provider → SDK → frontend). The GitHub provider
now fetches the PR title alongside existing status fields.
The agents sidebar now displays PR-state-aware icons for chats that have
a linked pull request (when the chat is in waiting/completed state):
- **Open PR**: `GitPullRequestArrow` (green)
- **Draft PR**: `GitPullRequestDraft` (gray)
- **Merged PR**: `GitMerge` (purple)
- **Closed PR**: `GitPullRequestClosed` (red)
Running/pending/paused/error chats keep their existing activity icons
(spinner, pause, error triangle).
### Changes
**Database migration** (`000432`): Adds `pull_request_title TEXT` and
`pull_request_draft BOOLEAN` columns to `chat_diff_statuses`.
**Backend pipeline**:
- `gitprovider.PRStatus` gains a `Title` field
- GitHub provider decodes the `title` from the API response
- `gitsync` and `coderd/chats.go` pass title + draft through to the DB
upsert
- `codersdk.ChatDiffStatus` exposes both new fields in the API response
**Frontend** (`AgentsSidebar.tsx`): New `getPRIconConfig()` function
resolves the appropriate Lucide git icon based on `pull_request_state`
and `pull_request_draft`. Only applies when the chat is in a terminal
state (waiting/completed).
**Real-time sync**: No changes needed — the existing
`diff_status_change` pubsub event already propagates the full
`ChatDiffStatus` including the new fields.
Adds a `created_by` column (nullable UUID) to the `chat_messages` table
to track which user created each message. Only user-sent messages
populate this field; assistant, tool, system, and summary messages leave
it null.
The column is threaded through the full stack: SQL migration, query
updates, generated Go/TypeScript types, db2sdk conversion, chatd
(including subagent paths), and API handlers. All API handlers that
insert user messages now pass the authenticated user's ID as
`created_by`.
No foreign key constraint was added, matching the existing pattern used
by `chat_model_configs.created_by`.
Adds offset and cursor-based pagination to the `GET
/api/experimental/chats` endpoint, following the exact same patterns
used by `GetUsers` and `GetTemplateVersionsByTemplateID`.
## Changes
### Database
- Add `after_id`, `offset_opt`, `limit_opt` params to
`GetChatsByOwnerID` SQL query
- Use composite `(updated_at, id) DESC` cursor for stable, deterministic
pagination
- Add migration with composite index on `chats (owner_id, updated_at
DESC, id DESC)`
### Backend
- Use `ParsePagination()` in `listChats` handler (matches `users.go`
pattern)
- Add `Pagination` field to `ListChatsOptions` SDK struct
### Frontend
- Add `infiniteChats()` query factory using `useInfiniteQuery` with
offset-based page params (same pattern as `infiniteWorkspaceBuilds`)
- Update `AgentsPage` to use `useInfiniteQuery`
- Add "Show more" button at the bottom of the agents sidebar (matches
`HistorySidebar` pattern)
- Keep existing `chats()` query for non-paginated uses (e.g., parent
chat lookup in `AgentDetail`)
### Tests
- Add `TestListChats/Pagination` covering `limit`, `after_id` cursor,
`offset`, and no-limit behavior
This change adds support for image attachments to chat via add button
and clipboard paste. Files are stored in a new `chat_files` table and
referenced by ID in message content. File data is resolved from storage
at LLM dispatch time, keeping the message content column small.
Upload validates MIME types via content type or content sniffing against
an allowlist (png, jpeg, gif, webp). The retrieval endpoint serves files
with immutable caching headers. On the frontend, uploads start eagerly
on attach with a background fetch to pre-warm the browser HTTP cache so
the timeline renders instantly after send.
To allow tasks to be shareable, we need to share both the `task`
resource and the `workspace` resource, and their sharing state needs to
be kept in sync. We've already implemented all of the necessary ACL
functionality for workspaces, so we can just sort of proxy those ACLs
back to the task as well.
Adds database columns and server-side logic to track interception lineage via tool call IDs. When an interception ends, the server resolves the correlating tool call ID to find the parent interception and links them via `parent_id`.
New `provider_tool_call_id` column on `aibridge_tool_usages` and `parent_id` column on `aibridge_interceptions`, with indexes for lookup. `findParentInterceptionID` queries by tool call ID and filters out the current interception to find the parent.
Adapted from the [coder/coder `dk/prompt_provenance_poc`](https://github.com/coder/coder/compare/main...dk/prompt_provenance_poc) branch.
Depends on [coder/aibridge#188](https://github.com/coder/aibridge/pull/188).
Closes https://github.com/coder/internal/issues/1334
## Summary
Remove the `workspace_agent_id` column from the `chats` table and
dynamically look up the first workspace agent instead.
## Problem
When a workspace is stopped and restarted, the workspace agent gets a
new ID. The `workspace_agent_id` stored on the chat at creation time
becomes stale, making the agent unreachable. This caused chats to break
after workspace restarts.
## Solution
Instead of persisting the agent ID, dynamically look up the first agent
from the workspace's latest build via
`GetWorkspaceAgentsInLatestBuildByWorkspaceID` whenever an agent
connection is needed. The `workspace_id` on the chat remains stable
across restarts.
This behavior may be refined later (e.g., agent selection heuristics),
but picking the first agent resolves the immediate breakage.
## Changes
- **Migration 000425**: Drop `workspace_agent_id` column from `chats`
- **SQL queries**: Remove `workspace_agent_id` from `InsertChat` and
`UpdateChatWorkspace`
- **chatd.go**: `getWorkspaceConn` and `resolveInstructions` now look up
agents dynamically from workspace ID
- **chatd.go**: Remove `refreshChatWorkspaceSnapshot` (no longer needed)
- **createworkspace.go**: Stop persisting agent ID when associating
workspace with chat
- **subagent.go**: Stop passing agent ID to child chats
- **SDK/frontend**: Remove `WorkspaceAgentID` / `workspace_agent_id`
from Chat type

Adds a nullable `last_error` column to the `chats` table so error
reasons survive page reloads.
**Backend:**
- Migration adds `last_error TEXT` (nullable) to chats
- `UpdateChatStatus` writes the error reason when status transitions to
`error`, clears it (NULL) on recovery
- `convertChat` maps `sql.NullString` to `*string` in the SDK
**Frontend:**
- Sidebar falls back to `chat.last_error` when no stream error reason is
cached
- Chat detail page does the same for `persistedErrorReason`
- Fixtures updated for new required field
## Summary
The UI has always labeled the action as "Archive agent" but the backend
was performing a hard `DELETE`, permanently destroying chats and all
their messages.
This change replaces the hard delete with a soft archive, consistent
with the pattern used by template versions.
## Changes
### Database
- **Migration 000423**: Add `archived boolean DEFAULT false NOT NULL`
column to `chats` table
- Replace `DeleteChatByID` query with `ArchiveChatByID` (`UPDATE SET
archived = true`)
- Add `UnarchiveChatByID` query (`UPDATE SET archived = false`)
- Filter archived chats from `GetChatsByOwnerID` (`WHERE archived =
false`)
### API
- Remove `DELETE /api/experimental/chats/{chat}`
- Add `POST /api/experimental/chats/{chat}/archive` — archives a chat
and all its descendants
- Add `POST /api/experimental/chats/{chat}/unarchive` — unarchives a
single chat (API only, no UI yet)
### Backend
- `archiveChatTree()` recursively archives child chats (replaces
`deleteChatTree()` which hard-deleted)
- Chat daemon's `ArchiveChat()` archives the full chat tree in a
transaction
- Authorization uses `ActionUpdate` instead of `ActionDelete`
### SDK
- Replace `DeleteChat()` with `ArchiveChat()` and `UnarchiveChat()`
- Add `Archived` field to `Chat` struct
### Frontend
- `archiveChat` API call uses `POST .../archive` instead of `DELETE`
- No UI changes — the "Archive agent" button now actually archives
instead of deleting
## Design Decision
This follows the **template version archive pattern** (Pattern B in the
codebase):
- `archived boolean` column (not `deleted boolean`)
- Dedicated `POST .../archive` and `POST .../unarchive` routes (not
repurposing `DELETE`)
- Reversible — users can unarchive via the API (UI for this will come
later)
The provisioner state for a workspace build was being loaded for every
long-lived agent rpc connection. Since this state can be anywhere from
kilobytes to megabytes this can gradually cause the `coderd` memory
footprint to grow over time. It's also a lot of unnecessary allocations
for every query that fetches a workspace build since only a few callers
ever actually reference the provisioner state.
This PR removes it from the returned workspace build and adds a query to
fetch the provisioner state explicitly.
## Summary
Harden the OAuth2 provider with multiple security fixes addressing
`coder/security#121` (CSRF session takeover) and converge on OAuth 2.1
compliance.
### Security Fixes
| Fix | Description | Commits |
|-----|-------------|---------|
| **CSRF on `/oauth2/authorize`** | Enforce CSRF protection on the
authorize endpoint POST (consent form submission) | `ba7d646`, `b94a64e`
|
| **Clickjacking: `frame-ancestors` CSP** | Prevent consent page from
being iframed (`Content-Security-Policy: frame-ancestors 'none'` +
`X-Frame-Options: DENY`) | `597aeb2` |
| **Exact redirect URI matching** | Changed from prefix matching to full
string exact matching per OAuth 2.1 §4.1.2.1 | `73d64b1`, `93897f1` |
| **Store & verify `redirect_uri`** | Store redirect_uri with auth code
in DB, verify at token exchange matches exactly (RFC 6749 §4.1.3) |
`50569b9`, `d7ca315` |
| **Mandatory PKCE** | Require `code_challenge` at authorization (for
`response_type=code`) + unconditional `code_verifier` verification at
token exchange | `d7ca315`, `1cda1a9` |
| **Reject implicit grant** | `response_type=token` now returns
`unsupported_response_type` error page (OAuth 2.1 removes implicit flow)
| `d7ca315`, `91b8863` |
### Changes by File
**`coderd/httpmw/csrf.go`** — Extended the CSRF `ExemptFunc` to enforce
CSRF on `/oauth2/authorize` in addition to `/api` routes. The consent
form POST is now CSRF-protected to prevent cross-site authorization code
theft.
**`site/site.go`** — Added `Content-Security-Policy: frame-ancestors
'none'` and `X-Frame-Options: DENY` headers to `RenderOAuthAllowPage`
(consent page only — does not affect the SPA/global CSP used by AI
tasks).
**`coderd/httpapi/queryparams.go`** — Changed `RedirectURL` from prefix
matching (`strings.HasPrefix(v.Path, base.Path)`) to full URI exact
matching (`v.String() != base.String()`), comparing scheme, host, path,
and query.
**`coderd/oauth2provider/authorize.go`** — Added PKCE enforcement:
`code_challenge` is required when `response_type=code` (via a
conditional check, not `RequiredNotEmpty`, so `response_type=token` can
reach the explicit rejection path). `ShowAuthorizePage` (GET) validates
`response_type` before rendering and returns a 400 error page for
unsupported types. `ProcessAuthorize` (POST) stores the `redirect_uri`
with the auth code when explicitly provided.
**`coderd/oauth2provider/tokens.go`** — PKCE verification is now
unconditional (not gated on `code_challenge` being present in DB). If
the stored code has a `redirect_uri`, the token endpoint verifies it
matches exactly — mismatch returns `errBadCode` → `invalid_grant`.
Missing `code_verifier` returns `invalid_grant`.
**`codersdk/oauth2.go`** — `OAuth2ProviderResponseTypeToken` constant
and `Valid()` acceptance are **kept** so the authorize handler can parse
`response_type=token` and return the proper `unsupported_response_type`
error rather than failing at parameter validation.
**`coderd/database/migrations/000421_*`** — Added `redirect_uri text`
column to `oauth2_provider_app_codes`.
### Design Decisions
**`state` parameter remains optional** — The plan initially required
`state` via `RequiredNotEmpty`, but this was reverted in `376a753` to
avoid breaking existing clients. The `state` is still hashed and stored
when provided (via `state_hash` column), securing clients that opt in.
**`response_type=token` kept in `Valid()`** — Removing it from `Valid()`
would cause the parameter parser to reject the request before the
authorize handler can return the proper `unsupported_response_type`
error. The constant is kept for correct error handling flow.
**CSP scoped to consent page only** — `frame-ancestors 'none'` is set
only on the OAuth consent page renderer, not globally. The SPA/global
CSP was previously changed to allow framing for AI tasks
([#18102](https://github.com/coder/coder/pull/18102)); this change does
not regress that.
### Out of Scope (follow-up PRs)
- Bearer tokens in query strings (needs internal caller audit)
- Scope enforcement on OAuth2 tokens
- Rate limiting on dynamic client registration

# Plan: Harden OAuth2 Provider — Security Fixes + OAuth 2.1 Compliance
## Context & Why
Security issue `coder/security#121` reports a critical session takeover
via CSRF on the OAuth2 provider. This plan covers all remaining security
fixes from that issue **plus** convergence on OAuth 2.1 requirements.
The goal is a single PR that closes all actionable gaps.
## Current State (already committed on branch `csrf-sjx1`)
| Fix | Status | Commits |
|-----|--------|---------|
| Fix 1: CSRF on `/oauth2/authorize` | ✅ Done | `ba7d646`, `b94a64e` |
| CSRF token in consent form HTML | ✅ Done | `b94a64e` |
| `state_hash` column + storage | ✅ Done (hash stored, but state still
optional) | `9167d83`, `b94a64e` |
| Tests for CSRF + state hash | ✅ Done | `e4119b5` |
## Remaining Work
### ~~Fix 2 — Require `state` parameter~~ (DROPPED)
> **Decision:** Do not enforce `state` as required. The `state`
parameter is still hashed and stored when provided (via
`hashOAuth2State` / `state_hash` column from prior commits), but clients
are not forced to supply it. This avoids breaking existing integrations
that omit state.
**Rollback:** Remove `"state"` from the `RequiredNotEmpty` call in
`coderd/oauth2provider/authorize.go:42`:
```go
// BEFORE (current on branch)
p.RequiredNotEmpty("response_type", "client_id", "state", "code_challenge")
// AFTER
p.RequiredNotEmpty("response_type", "client_id", "code_challenge")
```
No test changes needed — tests already pass `state` voluntarily.
### Fix 4 — Exact redirect URI matching
Currently `coderd/httpapi/queryparams.go:233` uses prefix matching:
```go
// CURRENT — prefix match
if v.Host != base.Host || !strings.HasPrefix(v.Path, base.Path) {
```
OAuth 2.1 requires **exact string matching**. Change to:
```go
// AFTER — exact match (OAuth 2.1 §4.1.2.1)
if v.Host != base.Host || v.Path != base.Path {
```
**File: `coderd/httpapi/queryparams.go` — `RedirectURL` method**
Also update the error message from "must be a subset of" to "must
exactly match".
**Additionally**, store `redirect_uri` with the auth code and verify at
the token endpoint (RFC 6749 §4.1.3):
1. **New migration** (same migration file or a new `000421`): Add
`redirect_uri text` column to `oauth2_provider_app_codes`
2. **Update INSERT query** in `coderd/database/queries/oauth2.sql` to
include `redirect_uri`
3. **`coderd/oauth2provider/authorize.go`**: Store
`params.redirectURL.String()` when inserting the code
4. **`coderd/oauth2provider/tokens.go`**: After retrieving the code from
DB, verify that `redirect_uri` from the token request matches the stored
value exactly. Currently `tokens.go:103` calls `p.RedirectURL(vals,
callbackURL, "redirect_uri")` for prefix validation only — it must
compare against the stored redirect_uri from the code, not just the
app's callback URL.
<details>
<summary>Why both exact match AND store+verify?</summary>
Exact matching at the authorize endpoint prevents open redirectors
(attacker can't use a sub-path).
Storing and verifying at the token endpoint prevents code injection — an
attacker who steals a code can't exchange it with a different
redirect_uri than was originally authorized. This is required by RFC
6749 §4.1.3 and OAuth 2.1.
</details>
### Fix 7 — `frame-ancestors` CSP on consent page
The consent page can be iframed by a workspace app (same-site), which is
the attack vector. Add a `Content-Security-Policy` header to prevent
framing.
**File: `site/site.go` — `RenderOAuthAllowPage` function (~line 731)**
Before writing the response, add:
```go
func RenderOAuthAllowPage(rw http.ResponseWriter, r *http.Request, data RenderOAuthAllowData) {
rw.Header().Set("Content-Type", "text/html; charset=utf-8")
// Prevent the consent page from being framed to mitigate
// clickjacking attacks (coder/security#121).
rw.Header().Set("Content-Security-Policy", "frame-ancestors 'none'")
rw.Header().Set("X-Frame-Options", "DENY")
...
```
Both headers for defense-in-depth (CSP for modern browsers,
X-Frame-Options for legacy).
### OAuth 2.1 — Mandatory PKCE
Currently PKCE is checked only when `code_challenge` was provided during
authorization (`tokens.go:258`):
```go
// CURRENT — conditional check
if dbCode.CodeChallenge.Valid && dbCode.CodeChallenge.String != "" {
// verify PKCE
}
```
OAuth 2.1 requires PKCE for ALL authorization code flows. Change to:
**File: `coderd/oauth2provider/authorize.go`** — Add `"code_challenge"`
to required params:
```go
p.RequiredNotEmpty("response_type", "client_id", "code_challenge")
```
**File: `coderd/oauth2provider/tokens.go:257-265`** — Make PKCE
verification unconditional:
```go
// AFTER — PKCE always required (OAuth 2.1)
if req.CodeVerifier == "" {
return codersdk.OAuth2TokenResponse{}, errInvalidPKCE
}
if !dbCode.CodeChallenge.Valid || dbCode.CodeChallenge.String == "" {
// Code was issued without a challenge — should not happen
// with the authorize endpoint enforcement, but defend in
// depth.
return codersdk.OAuth2TokenResponse{}, errInvalidPKCE
}
if !VerifyPKCE(dbCode.CodeChallenge.String, req.CodeVerifier) {
return codersdk.OAuth2TokenResponse{}, errInvalidPKCE
}
```
**File: `codersdk/oauth2.go`** — Remove
`OAuth2ProviderResponseTypeToken` from the enum or reject it explicitly
in the authorize handler. Currently it's defined at line 216 but the
handler ignores `response_type` and always issues a code. We should
either:
- (a) Remove the `"token"` variant from the enum and reject it with
`unsupported_response_type`, OR
- (b) Add an explicit check in `ProcessAuthorize` that rejects
`response_type=token`
Option (b) is simpler and more backwards-compatible:
```go
// In ProcessAuthorize, after extracting params:
if params.responseType != codersdk.OAuth2ProviderResponseTypeCode {
httpapi.WriteOAuth2Error(ctx, rw, http.StatusBadRequest,
codersdk.OAuth2ErrorCodeUnsupportedResponseType,
"Only response_type=code is supported")
return
}
```
### OAuth 2.1 — Bearer tokens in query strings
`coderd/httpmw/apikey.go:743` accepts `access_token` from URL query
parameters. OAuth 2.1 prohibits this. However, this may be used
internally (e.g., workspace apps, DERP). Need to audit callers before
removing.
**Approach:** This is a larger change with potential breakage. Mark as a
**separate follow-up issue** rather than including in this PR. Document
the finding.
### OAuth 2.1 — Removed flows
✅ **Already compliant.** `tokens.go` only supports `authorization_code`
and `refresh_token` grant types. The implicit grant
(`response_type=token`) will be explicitly rejected per the PKCE section
above.
### OAuth 2.1 — Refresh token rotation
✅ **Already compliant.** `tokens.go:442` deletes the old API key when a
refresh token is used.
## Migration Plan
All DB changes can go in a single new migration (or extend 000420 if the
branch is rebased before merge). Columns to add:
- `redirect_uri text` on `oauth2_provider_app_codes`
The `state_hash` column is already added by migration 000420.
## Implementation Order
1. **Fix 7** — CSP headers on consent page (isolated, no deps)
2. ~~**Fix 2** — Require `state` parameter~~ (DROPPED — state stays
optional)
3. **Fix 4** — Exact redirect URI matching + store/verify redirect_uri
4. **PKCE mandatory** — Require `code_challenge` + reject
`response_type=token`
5. **Rollback** — Remove `"state"` from `RequiredNotEmpty` in
`authorize.go`
6. **Tests** — Update/add tests for all changes
7. **`make gen`** after DB changes
## Out of Scope (separate PRs)
- Bearer tokens in query strings (needs internal caller audit)
- Scope enforcement on OAuth2 tokens
- Rate limiting / quota on dynamic client registration

_Generated with [`mux`](https://github.com/coder/mux) • Model:
`anthropic:claude-opus-4-6` • Thinking: `xhigh`_
Update provisionerdserver to handle the changes introduced to
provisionerd in https://github.com/coder/coder/pull/21602
We now create a relationship between `workspace_agent_devcontainers` and
`workspace_agents` with the newly created `subagent_id`.
This migration converts all tailnet coordination tables to UNLOGGED:
- `tailnet_coordinators`
- `tailnet_peers`
- `tailnet_tunnels`
UNLOGGED tables skip Write-Ahead Log (WAL) writes, significantly
improving performance for high-frequency updates like coordinator
heartbeats and peer state changes.
The trade-off is that UNLOGGED tables are truncated on crash recovery
and are not replicated to standby servers. This is acceptable for these
tables because the data is ephemeral:
1. Coordinators re-register on startup
2. Peers re-establish connections on reconnect
3. Tunnels are re-created based on current peer state
**Migration notes:**
- Child tables must be converted before the parent table because LOGGED
child tables cannot reference UNLOGGED parent tables (but the reverse is
allowed)
- The down migration reverses the order: parent first, then children
Fixes https://github.com/coder/coder/issues/21333
feat: add boundary usage telemetry database schema and RBAC
Adds the foundation for tracking boundary usage telemetry across Coder
replicas. This includes:
- Database schema: `boundary_usage_stats` table with per-replica stats
(unique workspaces, unique users, allowed/denied request counts)
- Database queries: upsert stats, get aggregated summary, reset stats,
delete by replica ID
- RBAC: `boundary_usage` resource type with read/update/delete actions,
accessible only via system `BoundaryUsageTracker` subject (not regular
user roles)
- Tracker skeleton + docs: stub implementation in `coderd/boundaryusage/`
The tracker accumulates stats in memory and periodically flushes to the
database. Stats are aggregated across replicas for telemetry reporting,
then reset when a new reporting period begins. The tracker implementation
and plumbing will be done in a subsequent commit/PR.

Removes the legacy tailnet v1 API tables (`tailnet_clients`, `tailnet_agents`, `tailnet_client_subscriptions`) and their associated queries, triggers, and functions. These were superseded by the v2 tables (`tailnet_peers`, `tailnet_tunnels`) in migration 000168, and the v1 API code was removed in commit d6154c4310, but the database artifacts were never cleaned up.
**Changes:**
- New migration `000410_remove_tailnet_v1_tables` to drop the unused tables
- Removed 11 unused queries from `tailnet.sql`
- Removed associated manual wrapper methods in `dbauthz` and `dbmetrics`
- ~930 lines deleted across 11 files
Creates migration 000409 with the database foundation for pausing and
resuming task workspaces.
The task_snapshots table stores conversation history (AgentAPI messages)
so users can view task logs even when the workspace is stopped. Each task
gets one snapshot, overwritten on each pause.
Three new build_reason values (task_auto_pause, task_manual_pause,
task_resume) let us distinguish task lifecycle events in telemetry and
audit logs from regular workspace operations.
Uses a regular table rather than UNLOGGED for snapshots. While UNLOGGED
would be faster, losing snapshots on database crash creates user confusion
(logs disappear until next pause). We can switch to UNLOGGED post-GA if
write performance becomes a problem.
Closescoder/internal#1250
Previously the `idx_custom_roles_name_lower` index prevented that.
A check constraint was also added to ensure the `organization_id` column cannot be set to the all-zero UUID.
closes: https://github.com/coder/internal/issues/858
Similar to https://github.com/coder/coder/pull/19375, this one uses
system permissions for fetching actual user and group data.
Modifies the `workspaces_expanded` view to fetch the required data; this way it's made available to all code paths that make use of it.
Also fixes a bug in a test helper function that can result in `null` being saved to the DB for `user_acl` or `group_acl` and break tests; a defensive check constraint that prevents this is worth a PR, e.g:
`ALTER TABLE workspaces
ADD CONSTRAINT group_acl_is_object CHECK (jsonb_typeof(group_acl) = 'object');`
Also adds missing `OwnerName` in `ConvertWorkspaceRows`.
## Context
GetWorkspaceAgentByInstanceID has a suboptimal plan. Even though it is
designed to fetch a small subset of records, there are no corresponding
indexes and that query results in full table scan:
Query:
```
SELECT id, auth_instance_id FROM workspace_agents
where auth_instance_id='i-013c2b96b6441648a' and deleted=FALSE;
```
Plan:
```
------------------------------------------------------------------------------------------------------------------
Seq Scan on workspace_agents (cost=0.00..222325.48 rows=2 width=36) (actual time=0.012..234.152 rows=4 loops=1)
Filter: ((NOT deleted) AND ((auth_instance_id)::text = 'i-013c2b96b6441648a'::text))
Rows Removed by Filter: 302276
Planning Time: 0.173 ms
Execution Time: 234.169 ms
```
After adding the index, the plan improves drastically.
Updated plan:
```
Bitmap Heap Scan on workspace_agents (cost=4.44..12.32 rows=2 width=36) (actual time=0.019..0.019 rows=0 loops=1)
Recheck Cond: (((auth_instance_id)::text = 'i-013c2b96b6441648a'::text) AND (NOT deleted))
-> Bitmap Index Scan on workspace_agents_auth_instance_id_deleted_idx (cost=0.00..4.44 rows=2 width=0) (actual time=0.013..0.014 rows=0 loops=1)
Index Cond: (((auth_instance_id)::text = 'i-013c2b96b6441648a'::text) AND (deleted = false))
Planning Time: 0.388 ms
Execution Time: 0.044 ms
```
## Changes
* add an index to optimize this query
## Testing
* ran the queries manually against prod and test DBs
* ran `./scripts/develop.sh`, connected to the local PostgreSQL
instance, inspected the indexes to make sure new index is there:
```
Indexes:
"workspace_agents_pkey" PRIMARY KEY, btree (id)
// NEW INDEX CREATED SUCCESSFULLY [comment is mine]
"workspace_agents_auth_instance_id_deleted_idx" btree (auth_instance_id, deleted)
"workspace_agents_auth_token_idx" btree (auth_token)
"workspace_agents_resource_id_idx" btree (resource_id)
```

## Problem
Tasks currently only expose a machine-friendly name field (e.g.
`task-python-debug-a1b2`), but this value is primarily an identifier
rather than a clean, descriptive label. We need a separate
display-friendly name for use in the UI.
This PR introduces a new `display_name` field and updates the task-name
generation flow. The Claude system prompt was updated to return valid
JSON with both `name` and `display_name`. The name generation logic
follows a fallback chain (Anthropic > prompt sanitization > random
fallback). To make task names more closely resemble their display names,
the legacy `task-` prefix has been removed. For context, PR
https://github.com/coder/coder/pull/20834 introduced a small Task icon
to the workspace list to help identify workspaces associated to tasks.
## Changes
- Database migration: Added `display_name` column to tasks table
- Updated system prompt to generate both task name and display name as
valid JSON
- Task name generation now follows a fallback chain: Anthropic > prompt
sanitization > random fallback
- Removed `task-` prefix from task names to allow more descriptive names
- Note: PR https://github.com/coder/coder/pull/20834 adds a Task icon to
workspaces in the workspace list to distinguish task-created workspaces
**Note:** UI changes will be addressed in a follow-up PR

This change restructures the `tasks_with_status` view query to:
- Improve debuggability by adding a `status_debug` column to better
understand the outcome
- Reduce clutter from `bool_or`, `bool_and` which are aggregate
functions that did not actually have serve a purpose (each join is 0-1
rows)
- Improve agent lifecycle state coverage, `start_timeout` and
`start_error` were omitted
- These states are easy to trigger even in a perfectly functioning
workspace/task so we now rely on app health to report whether or not
there was an issue
- Mark canceling and canceled workspace build jobs as error state
- Agent stop states were implicitly `unknown`, now there are explicit (I
initially considered `error`, could go either way)
For experimental and dogfood purposes, this adds the ability to opt in a single template.
Leaving the rest of the templates as is.
For GA, this setting might be removed or changed.

If the workspace relating to a task was deleted, most of the
workspace-related fields in `taskFromDBTaskAndWorkspace` will be
zero-valued. However, we can still get information relating to the owner
so that "created by" shows up correctly in the UI.
Updates the `tasks_with_status` view with a join on `visible_users` to
get owner-related info.
- Adds a new table to keep track of which payloads have already been
reported since we only report for the last clock hour
- Adds a query to gather and aggregate all the data by
provider/model/client

Add API key allow list to the SDK
This PR adds an allow list to API keys in the SDK. The allow list is a list of targets that the API key is allowed to access. If the allow list is empty, a default allow list with a single entry that allows access to all resources is created.
The changes include:
- Adding a default allow list when generating an API key if none is provided
- Adding allow list to the API key response in the SDK
- Converting database allow list entries to SDK format in the API response
- Adding tests to verify the default allow list behavior
Fixes#19854
