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

Parent agents were re-using AuthInstanceID when spawning child agents.
This caused GetWorkspaceAgentByInstanceID to return the most recently
created sub agent instead of the parent when the parent tried to refetch
its own manifest.
Fix by not reusing AuthInstanceID for sub agents, and updating
GetWorkspaceAgentByInstanceID to filter them out entirely.
Adds coderd_template_workspace_build_duration_seconds histogram that
tracks the full duration from workspace build creation to agent ready.
This captures the complete user-perceived build time including
provisioning and agent startup.
The metric is emitted when the agent reports ready/error/timeout via the
lifecycle API, ensuring each build is counted exactly once per replica.
Previously, UpsertBoundaryUsageStats (INSERT...ON CONFLICT DO UPDATE) and
GetAndResetBoundaryUsageSummary (DELETE...RETURNING) could race during
telemetry period cutover. Without serialization, an upsert concurrent with the
delete could lose data (deleted right after being written) or commit after the
delete (miscounted in the next period). Both operations now acquire
LockIDBoundaryUsageStats within a transaction to ensure a clean cutover.
Task snapshots were orphaned when tasks were soft-deleted. The
`task_snapshots` table has an `ON DELETE CASCADE` foreign key, but
that only fires on hard deletes.
Modified DeleteTask to use a CTE that atomically soft-deletes the
task and removes its snapshot in a single transaction. The query now
returns just the task UUID instead of the full row.
Closescoder/internal#1283
Adds support for filtering workspaces by health status using
healthy:true or healthy:false in the search query.
This is done by changing `has-agent` to accept a list of statuses and
aliasing `health:true` to `has-agent:connected` and `healthy:false` to
`has-agent:timeout,disconnected`.
Fixes#21623
The AcquireProvisionerJob query only checked started_at IS NULL, allowing
it to acquire jobs that were canceled while pending (which have
completed_at set but started_at still NULL).
Added completed_at IS NULL check to the query to prevent this.
Also fixed JobCompleteBuilder.Do() in dbfake to set started_at when
completing jobs to match production behavior.
Fixescoder/internal#1323
Previously there were two issues that could cause incorrect boundary
usage telemetry data.
1. Bad handling across snapshot intervals: After telemetry snapshot deleted
the DB row, the next flush would INSERT the stale cumulative data (which
included already-reported usage). This would then be overwritten by
subsequent UPDATE flushes, causing the delta between the last snapshot
and the reset to be lost (under-reporting usage). Additionally, if there
was no new usage after the reset, the tracker would carry over all usage
from the previous period into the next period (over-reporting usage).
2. Missed usage from a race condition: Track() calls between the first
mutex unlock and second mutex lock in FlushToDB() were lost. The data
wasn't included in the current flush (already snapshotted) and was wiped
by the subsequent reset. This is likely low impact to overall usage
numbers in the real world.
Fix by tracking unique workspace/user deltas separately from cumulative
values and always tracking delta allowed/denied requests. Deltas are used
for INSERT (fresh start after reset), cumulative for UPDATE (accurate unique
counts within a period). All counters reset atomically before the DB operation
so Track() calls during the operation are preserved for the next flush.
Closes#21044
This pull-request addresses an issue we were seeing where we would
attempt to filter the `<UserCombobox />` by the users username or email
not their username (which the rendered options would show).
To highlight this I created three different users. Each with a username
that did not contain their `email` or `name` and attempted to filter.
Attempting to search for `John` wouldn't actually show the user as his
username was `x`, and infact whereas a subset of users might be returned
from the backend for having `john` in the `email` it would've been
filtered by the frontend for not being in the `name` field.
| Name | Username |
| --- | --- |
| `Jake` | `z` |
| `Jeff` | `y` |
| `John` | `x` |
| Previously | Now |

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`.
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.

This change adds a POST /workspaceagents/me/tasks/{task}/log-snapshot
endpoint for agents to upload task conversation history during
workspace shutdown. This allows users to view task logs even when the
workspace is stopped.
The endpoint accepts agentapi format payloads (typically last 10
messages, max 64KB), wraps them in a format envelope, and upserts to the
task_snapshots table. Uses agent token auth and validates the task
belongs to the agent's workspace.
Closescoder/internal#1253
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
Agents were losing authentication during workspace shutdown, causing
shutdown scripts to fail. The auth query required agents to belong to
the latest build, but during shutdown a `stop` build becomes latest while
the `start` build's agents are still running.
Modified the auth query to allow `start` build agents to authenticate
temporarily during `stop` execution. The query allows auth when:
- Agent's `start` build job succeeded
- Latest build is `stop` with `pending`/`running` job status
- Builds are adjacent (`stop` is `build_number + 1`)
- Template versions match
Auth closes once `stop` completes.
Renamed `GetWorkspaceAgentAndLatestBuildByAuthToken` to
`GetAuthenticatedWorkspaceAgentAndBuildByAuthToken` since it returns the
agent's build (not always latest) during shutdown.
Closes coder/internal#1249
Fixes#19467
Relates to https://github.com/coder/internal/issues/1214
The `ExtractWorkspaceAgentParam` middleware ends up making 4 database
queries to follow the chain of `WorkspaceAgent` -> `WorkspaceResource`
-> `ProvisionerJob` -> `WorkspaceBuild` -- but then dropping all that
hard work on the floor. The `api.workspaceAgent` handler that references
this middleware then has to do all of that work again, plus one more
query to get the related `User` so we can get the username. This pattern
is also mirrored in `getDatabaseTerminal` but without the middleware.
This PR:
* Adds a new query `GetWorkspaceAgentAndWorkspaceByID` to fetch all
this information at once to avoid the multiple round-trips,
* Updates the existing usage of `GetWorkspaceAgentByID` to this new
query instead,
* Updates `ExtractWorkspaceAgentParam` to also store the workspace in
the request context
Dalibo: [0.63ms](https://explain.dalibo.com/plan/40bb597f3539gc6c)
Adds a per-organization setting to disable workspace sharing. When enabled,
all existing workspace ACLs in the organization are cleared and the workspace
ACL mutation API endpoints return `403 Forbidden`.
This complements the existing site-wide `--disable-workspace-sharing` flag by
providing more granular control at the organization level.

Update user last_seen_at when we mark them active on login. This prevents a narrow race where they can be re-marked dormant and fail to log in.
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`.
Previously the GetTemplateVersionVariables query did not sort output,
relying on PostgreSQL on-disk ordering which is undeterministic.
Variables are now sorted by name because there is no alternative for
ordering.
Tests were adjusted to accommodate the new ordering, previously they
relied on data being written to disk in insert order.
In this PR we're optimizing the `GetTemplateAppInsightsByTemplate` query
by pre-filtering out apps which do not have an active session during the
start/end time window.

To summarize, the current version of this query selects from
`workspace_agent_stats` twice. The expensive portion of this query is
the bitmap heap scan we have to do for each of these selects. We can
easily cut the cost of this query by 40-50% by cutting this down to a
single select, and using those rows for both sets of calculations.
Eliminating the heap scan itself would require a follow up PR to
introduce a new index. Blink helped with the rewrite of the query.
The current plan looks like this:

If we compare the results of the query they're similar enough that any
differences can be attributed to slightly different timestamps for
`now()` in the version of the query I am using to generate results for

Previously setting AI Bridge retention to 0 would cause records to be
deleted immediately since we didn't check for the zero value before
calculating the deletion threshold.
This adds a check for aibridgeRetention > 0 to skip deletion when
retention is disabled, matching the pattern used for other retention
settings (connection logs, audit logs, etc.).
Also fixes the return type of DeleteOldAIBridgeRecords from int32 to
int64 since COUNT(*) returns bigint in PostgreSQL.
Refs #21055
Replace hardcoded 7-day retention for workspace agent logs with
configurable retention from deployment settings. Defaults to 7d to
preserve existing behavior.
Depends on #21038
Updates #20743
Replace hardcoded 7-day retention for expired API keys with configurable
retention from deployment settings. Skips deletion entirely when effective
retention is 0.
Depends on #21021
Updates #20743
Add configurable retention policy for audit logs. The DeleteOldAuditLogs
query excludes deprecated connection events (connect, disconnect, open,
close) which are handled separately by DeleteOldAuditLogConnectionEvents.
Disabled (0) by default.
Depends on #21021
Updates #20743
Add `DeleteOldConnectionLogs` query and integrate it into the `dbpurge`
routine. Retention is controlled by `--retention-connection-logs` flag.
Disabled (0) by default.

Updates #20743
## Problem
Users may not realize that task notifications are disabled by default.
To improve awareness, we show a warning alert on the Tasks page when all
task notifications are disabled.
**Alert visibility logic:**
- Shows when **all** task notification templates (Task Working, Task
Idle, Task Completed, Task Failed) are disabled
- Can be dismissed by the user, which stores the dismissal in the user
preferences API
- If the user later enables any task notification in Account Settings,
the dismissal state is cleared so the alert will show again if they
disable all notifications in the future

/>
## Changes
- Added a warning alert to the Tasks page when all task notifications
are disabled
- Introduced new `/users/{user}/preferences` endpoint to manage user
preferences (stored in `user_configs` table)
- Alert is dismissible and stores the dismissal state via the new user
preferences API endpoint
- Enabling any task notification in Account Settings clears the
dismissal state via the preferences API
- Added comprehensive Storybook stories for both TasksPage and
NotificationsPage to test all alert visibility states and interactions
Closes: https://github.com/coder/internal/issues/1089
Closes https://github.com/coder/coder/issues/20913
I've ran the test without the fix, verified the test caught the issue,
then applied the fix, and confirmed the issue no longer happens.

## Description
This PR fixes an issue where `GetLatestWorkspaceAppStatusesByAppID`
returned an unbounded number of rows for a given app ID, which could
cause performance issues for noisy or long-running AI tasks.
## Impact
This change reduces database query overhead for workspace app status
updates, particularly for busy AI tasks that update their status
frequently. Previously, fetching the latest status would return all
historical statuses, now it returns only the most recent one.
Fixes#20862

## 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

Addresses [`aibridge#54`](https://github.com/coder/aibridge/issues/54)
When querying against the values in the database for
`/api/experimental/aibridge/interceptions` we found strange behaviour
wherein there was interceptions that lacked prompting and other various
fields we want. Generally this was as a result of the data not actually
existing for these values (as they were inflight).
The simple solution to this was to hide them if they didn't exist. This
PR addresses that.

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.
* Adds a `GetTaskByOwnerIDAndName` query
* Updates `httpmw.TaskParam` to fall back to task name if no task by
UUID found.
* Updates the `TaskByIdentifier` used in `cli/` to use direct lookup instead of searching.
