Michael Suchacz 6b8f820493 feat: remove native chat cost tracking in favor of AI Gateway cost data (#27330)
## Stack Context

This stack makes AI Gateway data and budgets the source of truth for AI
spend controls.

1. Re-back the per-chat cost endpoint with AI Gateway data (#27328,
merged).
2. Remove native chat usage limits (#27329, merged).
3. **This PR, now based on `main`:** remove native chat cost tracking
and its dedicated admin UI.

## Summary

Removes native per-message price calculation, model pricing fields, cost
persistence, aggregate cost queries, and admin cost API types. It also
deletes the Analytics and Spend pages plus their legacy redirects. The
AI Gateway-backed per-chat cost row and compact budget indicators
remain.

The spend documentation is renamed to `spend-management.md` and updated
for the remaining surfaces, group budget APIs, CSV export, upgrade
handling for native pricing and cost history, and the absence of a
deployment-wide spend dashboard. The per-chat cost API documents that
data follows AI Gateway retention and reports zero after all matching
requests are purged.

No schema is dropped in this release. `chat_messages.total_cost_micros`
remains nullable and unwritten so replicas from the previous release can
continue inserting messages during rolling upgrades. #27600 tracks
removal after the compatibility window.

Michael Suchacz f0e6ac64b3 feat: remove native chat usage limits in favor of AI Gateway budgets (#27329)
## Stack Context

This stack makes AI Gateway data and budgets the source of truth for AI
spend controls.

1. Re-back the per-chat cost endpoint with AI Gateway data (#27328,
merged).
2. **This PR:** remove native chat usage limits.
3. Remove native chat cost tracking and its dedicated admin UI (#27330).

## Summary

Removes the native usage-limit API, SDK types, SQL, and chat enforcement
for deployment, user, and group chat limits. Compact AI Gateway budget
indicators remain in the Agents sidebar, user menu, and group settings.
Gateway budget rejections and provider quota failures continue to
classify as usage-limit errors, including a 409 response for synchronous
title generation.

Budget-period labels now use the API's UTC boundaries, so users see the
same dates in every browser timezone. The documentation explains the AI
Gateway replacement, its licensing requirements, and the differences
from native limits.

No schema is dropped in this release. The usage-limit table, index, user
and group columns, constraints, audit mappings, and generated scan
fields remain for mixed-version rolling upgrades. #27600 tracks their
removal after the compatibility window.

## Breaking change

Native day, week, and month chat spend limits are removed and are not
migrated. AI Gateway budgets are month-based, group-scoped with per-user
overrides, and require the AI Gateway entitlement. Deployments without
that entitlement no longer have chat spend enforcement.

Jaayden Halko 54d5eb7ec2 feat: add hourly hb_agent_runtime_v1 usage events for Coder Agent runtime (#27312)
closes CODAGT-839
closes CODAGT-843
closes CODAGT-773

## Summary

Adds a new heartbeat usage event type, `hb_agent_runtime_v1`, measuring
the total agent-loop runtime of Coder Agents (chats) per UTC hour, plus
a reconciler that generates one event per hour with self-healing
backfill over a trailing 7-day window. Events flow to Tallyman through
the existing publisher unchanged. This measures the new Coder Agents
(the `chats` tables), not the deprecated Tasks counted by
`dc_managed_agents_v1`.

Independent of #27508, which fixes the dead ai-seats cron registration.
Both PRs carry the identical `usage_event` create permission hunk for
the usage-publisher subject (this feature's generator and the ai-seats
cron each need it for heartbeat inserts), so they can land in either
order and the overlap merges cleanly.

> [!WARNING]
> **Do not include this in a release until Tallyman accepts
`hb_agent_runtime_v1`.** The publisher marks permanently rejected events
as done-forever, and the generator then sees those buckets as complete
locally, so their usage would be silently and permanently lost.

## Details

Each event's payload is `{"runtime_ms": N}`: the sum of
`chat_messages.runtime_ms` for messages created in the hour bucket `[H,
H+1)`, across all chats (sub-agents, API-created, archived, and
soft-deleted messages included). Events use deterministic IDs
(`hb_agent_runtime_v1:<bucket start>`) with `created_at` set to the
bucket start, so concurrent replicas race safely via `ON CONFLICT (id)
DO NOTHING` without locking, and daily rollups attribute backfilled
hours to the correct day. Idle hours produce zero-valued events. A
bucket becomes eligible 5 minutes after it closes; hours missing for
longer than the 7-day window are forfeited, which can only undercount.

Note that this makes `usage_events.created_at` explicitly the *event
occurrence time* rather than the row insertion time; the two only
diverge for backfilled events. It already behaved as the occurrence
timestamp (it drives the daily rollup day and is shipped to
Tallyman/Metronome as the event timestamp), and the migration now
documents this with a `COMMENT ON COLUMN`, which also surfaces as a Go
doc comment on `UsageEvent.CreatedAt`.

The new `usage.Generator` runs unconditionally in enterprise builds; the
`publish_usage_data` license flag continues to gate egress only, so
air-gapped deployments still fill their local ledger. The
`aggregate_usage_event()` trigger sums `runtime_ms` per day into
`usage_events_daily` (unlike `hb_ai_seats_v1`, which takes the daily
max).

`InsertHeartbeatUsageEvent` now takes an explicit `createdAt` so
generators can backfill historical buckets; the cron passes
`clock.Now()` to preserve its existing behavior.

## Tallyman follow-up

<details>
<summary>Prompt for the Tallyman-repo agent</summary>

> **Task**: Add support for the new Coder usage event type
`hb_agent_runtime_v1` so Tallyman accepts, validates, and forwards it to
Metronome.
>
> **Background**: coder/coder PR (this PR) adds hourly heartbeat events
measuring Coder Agent runtime. Events arrive via the existing
`/api/v1/events/ingest` endpoint with: `event_type:
"hb_agent_runtime_v1"`, `event_data: {"runtime_ms": <int64 >= 0>}`,
deterministic `id` of the form `hb_agent_runtime_v1:2026-07-15_14:00:00`
(UTC hour bucket start), and `created_at` set to the bucket start (may
be up to ~8 days in the past due to backfill; within Metronome's 34-day
dedup window). Zero-value events are normal (idle hours).
>
> **Work**:
> 1. Update Tallyman's vendored/imported `coderd/usage/usagetypes` (or
equivalent) to the coder/coder commit that adds
`UsageEventTypeHBAgentRuntimeV1` and `HBAgentRuntime`.
> 2. Ensure ingestion validation accepts the type (`Valid()` switches)
and rejects negative `runtime_ms`.
> 3. Ensure Metronome forwarding maps the event with transaction ID
derived from the event `id` as for existing types, passing `runtime_ms`
through as the property for a SUM-aggregated billable metric ("Coder
Agent Hours" = `SUM(runtime_ms) / 3,600,000`).
> 4. Do NOT permanently reject unknown-but-well-formed future `hb_*`
types if avoidable; at minimum confirm current behavior for unknown
types (temporary vs permanent rejection) and report it.
> 5. Tests: ingest accept/validate, dedup by ID, Metronome payload
mapping.
>
> **Constraint**: this must be deployed to tallyman-prod **before** any
coder/coder release containing the event generator; coderd treats
permanent rejections as terminal per event.

Michael Suchacz 1c722ff969 fix(coderd/database): order the chat prompt query and its boundary by id (#27619)
## Stack context

Follows #27495 (merged), which gives `chat_messages.id` an append-order
guarantee and moves the history reads onto it. This PR applies the same
fix to the query that builds the model prompt.

## Why?

`GetChatMessagesForPromptByChatID` mixed two orderings. It selected the
compaction boundary with `created_at DESC, id DESC`, then applied that
boundary with an `id >` comparison, and returned rows with `created_at
ASC, id ASC`.

`created_at` is `now()`, so it is the transaction start time. Every row
in one insert batch shares it, and concurrent transactions can commit in
the opposite order to the one they started in. Two consequences, both
reaching the provider:

- **Malformed prompts.** A tool result could be ordered ahead of the
assistant message that requested it.
`chatprompt.injectMissingToolResults` does not repair this: it only
handles tool rows already contiguous after an assistant row, and adds
missing results. It never moves a tool row that precedes its assistant,
and nothing re-sorts the rows in Go.
- **Wrong compaction boundary.** The boundary is picked by timestamp but
compared by id, so a stale compressed summary could be retained while
the actual latest one was dropped.

## Changes

Both the boundary CTE and the outer query order by `id`. The `id >`
predicate is unchanged, which is the point: the ordering now matches the
comparison that was always being made.

**The boundary index was dead, so it is rebuilt to match.**
`idx_chat_messages_compressed_summary_boundary` was created for exactly
this lookup, but its predicate requires `role = 'system'` while
compaction writes its summary with the user role
(`message_conversion.go:334`, the only writer of `compressed = true`).
It matched zero rows, and no other query can use it. Migration `000560`
rebuilds it as `(chat_id, id DESC) WHERE compressed AND NOT deleted AND
visibility = 'model'`, which also matches the new order key.

Measured on PostgreSQL 13 with a 20k-message chat, 11 summaries, and 14
sibling chats so `chat_id` is selective:

| boundary lookup | plan | buffers |
|---|---|---|
| old predicate | Index Scan `idx_chat_messages_chat`, 19,989 rows
filtered | 267 |
| rebuilt index | Index Only Scan | 2 |

Not in scope: the outer `SELECT` still inspects every row of the chat,
because its `role = 'system' AND compressed = FALSE` disjunct has no
lower `id` bound. That predates this PR and needs a query rewrite rather
than an index.

## Testing

Two subtests, both verified red by reverting the `ORDER BY` and
regenerating:

- `OrdersByIDWhenTimestampsDisagree` returned `[4,3,2,1]` instead of
`[1,2,3,4]`, placing the tool result before the assistant call.
- `CompactionBoundaryUsesID` selected the stale summary and leaked the
messages between the two summaries into the prompt.

Existing subtests pass unchanged. Migration up/down tests pass, and the
rebuilt index was verified red-green: restoring the old predicate
returns the plan to a 267-buffer scan, and the old predicate matches 0
rows in the fixture.

Michael Suchacz 91c7232d97 feat: add chat suffix messages, idle failure, and content update support (#27428)
Adds generic chat state and query capabilities that the lifecycle hooks
integration (#27429) builds on. Part of the lifecycle hooks stack
(#27401, #27429, #27430).

- `chatstate`: `EditMessage` accepts caller-provided suffix messages
inserted after the replacement in the same transaction, transitions can
carry a typed error kind, and `FinishError` is also allowed from waiting
chats so admission-time failures can park an idle chat in error.
- `chatstate`: `ValidateToolResults` holds the submitted-tool-result
rules (duplicate, invalid JSON, missing, unexpected) in one place, so
`CompleteRequiresAction` and API-level prechecks reject the same
payloads with the same typed causes.
- `database`: `InsertChat` accepts an optional caller-provided ID.

No hook-specific state or behavior is introduced here; these primitives
are usable by any caller.

An earlier revision added a message-content rewrite primitive so a
`pre_tool_use` override could update an already-committed tool call.
Message content is immutable by design, and @hugodutka pushed back on
changing that. The rewrite is gone: #27429 now dispatches the hook
before the assistant message is stored, so the stored input is the one
that runs and nothing needs updating.

Michael Suchacz e96d8646e2 fix(coderd): give chat message ids an append-order guarantee (#27495)
Chat message ordering was derived from `created_at`, which is `now()`
and therefore the transaction start time. That makes it unusable as an
append-order column for two independent reasons: every row in one
`InsertChatMessages` batch shares a single timestamp, and two concurrent
transactions can commit in the opposite order to the one they started
in.

This PR gives `chat_messages.id` a real append-order guarantee and moves
the history reads onto it.

## Changes

**`InsertChatMessages` had no input-order guarantee.** Callers index the
returned slice by input position. That only worked because PostgreSQL
happens to evaluate the `BIGSERIAL` default in row order. Ids are now
allocated up front and the k-th smallest is assigned to input index k,
so the pairing does not depend on where the column default is evaluated.
Returned rows are explicitly `ORDER BY id`.

**Three history reads now order by `id`.**

| Query | Was | Now |
|---|---|---|
| `GetChatMessagesByChatID` | `created_at ASC` | `id ASC` |
| `GetChatMessagesByRevisionForStream` | `created_at ASC, id ASC` | `id
ASC` |
| `GetLastChatMessageByRole` | `created_at DESC, id DESC` | `id DESC` |

`GetChatMessagesByChatID` paginated by `id` while ordering by
`created_at`, which is incoherent on its own terms.

The other two matter because of who consumes them. The stream query
supplies incremental updates on the same socket that emits a full
`GetChatMessagesByChatID` snapshot on history reset, so once that
snapshot moved to `id` the two disagreed under timestamp skew.
`GetLastChatMessageByRole` returns an id that is then used as an id
cursor, both as `AfterID` when synthesizing tool cancellations and as
`chats.last_read_message_id`, where a stale anchor leaves later
assistant messages permanently unread.

A tie-breaker would not have fixed either one. It only resolves equal
timestamps; leading with `created_at` is the actual defect.

**`GetLastChatMessageByRole` loses its index, so this adds one.** `ORDER
BY created_at DESC, id DESC` could take an ordered scan of
`idx_chat_messages_chat_created`. Nothing in the schema can supply
`ORDER BY id DESC LIMIT 1` for a given `chat_id` and `role`, so the
planner switches to a backward scan of the primary key and filters every
newer row in the table, scanning all of it when the chat has no message
in that role, which is the routine case for a fresh chat. Migration
`000559` adds `(chat_id, role, id DESC) WHERE deleted = false`, the same
shape as the existing `idx_chat_messages_user_prompts`. This matters
because the query is hot: it runs on every stream connect and
disconnect, and once per turn when synthesizing tool cancellations.

`GetChatMessagesForPromptByChatID` has the same defect and is fixed in
the stacked PR, because its compaction boundary change is semantic and
deserves a separate review. Auto-archive stays timestamp-based
deliberately: it measures activity, not order.

Wrapping the insert in a CTE (needed because `INSERT` cannot take `ORDER
BY`) makes sqlc synthesize `InsertChatMessagesRow`. It is structurally
identical to `ChatMessage`, so the call sites use a direct struct
conversion that stops compiling if the two ever diverge.

## Testing

Behavior tests write `created_at` values inverted against id order, so a
reader that leads with `created_at` returns the batch backwards. All
three queries were verified red by reverting the `ORDER BY` and
regenerating: the stream query returned `[3,2,1]` for `[1,2,3]`, and
`GetLastChatMessageByRole` picked id 1 instead of id 3.

`TestInsertChatMessagesOrderContract` asserts against the generated SQL,
covering what a behavior test cannot: PostgreSQL evaluates the id
default in row order anyway, so a batch still looks ordered once the
guarantee is removed.

`TestChatMessagesSequenceCacheIsOne` guards the cross-batch half of the
invariant. Ids follow chat row lock order only while the sequence hands
out one value at a time; sequence cache blocks are per session, so with
a cache above one a backend holding stale cached values can lock second
and still commit lower ids. Bumping a sequence cache is an ordinary
throughput tweak, and it would silently corrupt history order.

The index was checked on a 200k row fixture. Without it, the zero-match
lookup filters all 200,000 rows over 2763 buffers; with it, the plan is
an index scan with both `chat_id` and `role` in the index condition, no
sort node, and 3 buffers.

Note that the within-batch mapping does not depend on the cache size. It
is established by `ROW_NUMBER() OVER (ORDER BY id)` over the allocated
ids, so it holds regardless of `nextval` evaluation order.

## Note on the deleted subagent hand-sort

The subagent history reader's hand-sort stays deleted, but calling it
redundant was imprecise. It sorted by `created_at` then `id`, so it is
only equivalent to `id` ordering when the two agree. When they disagree
the old code selected a different "latest assistant". This is a
deliberate behavior change to match the new invariant, not dead-code
removal.

Jaayden HalkoandCursor 6f2011af88 feat: add chat summary tab in the right sidebar and per-chat cost endpoint (#26649)
Stacked on #26657 (the persisted whole-chat summary backend). Base
branch is `chat-summary-62j9`; review/merge that first.

Adds a reusable `ChatSummary` component.

The summary text is the persisted whole-chat summary (`chat.summary`)
introduced by #26657. It is generated asynchronously and may be `null`
until the first summary is produced, in which case the popover renders a
muted empty state. Live updates arrive via that PR's
`chat_summary_change` watch event, which is already merged into the chat
caches.

Cost is served by a new per-chat endpoint, `GET
/api/experimental/chats/{chat}/cost`, which rolls up assistant-message
cost across a chat's root and child (subagent) chats and is authorized
like the other `{chat}` routes (read on the chat, 404 otherwise).

Visual and interaction coverage lives in `ChatSummary.stories.tsx` and
`ChatSummaryPopover.stories.tsx` (including populated-summary,
empty-state, and cost-loading cases).

Jaayden HalkoandCursor 3c7a1d33e3 feat: add persisted whole-chat summary with background generation (#26657)
Adds a persisted whole-chat summary that backs the chat summary popover.
A new nullable `chats.summary` column is populated in the background
after a successful root-chat turn and pushed to clients via a new
`chat_summary_change` watch event (distinct from `summary_change`, which
is bound to `last_turn_summary`), so the popover reads `chat.summary`
straight off the loaded `Chat` with no extra query.

This is the data source for the popover and per-chat cost UI built in
#26649; the popover can consume `chat.summary` once this lands (the
field is nullable, so merge order does not matter).

## How it works

- **Generation** runs in the existing successful-turn finalize hook,
detached from the request so the user's turn is never blocked. A cadence
gate generates the first summary after one completed turn, then
regenerates every three turns, using the `chats.summary_generated_at`
freshness marker. Generation reads compaction-aware history, renders it
to a bounded plain-text transcript (short transcripts are skipped), and
asks for a 1-3 sentence summary via structured output. Failures never
clear an existing summary.
- **Staleness** is guarded by `history_version` (mirroring
`last_turn_summary`), so a background write racing a newer turn loses
while worker lifecycle transitions cannot reject a fresh write.
- **Model selection** uses the chat's configured model.

## Deferred to follow-ups

- **Cost accounting**: the `chat_messages.cost_source` discriminator and
summary/title usage recording were removed from this PR so summary
persistence is not blocked by hidden accounting rows advancing
`history_version`. Title usage recording stays on main's
`InsertChatMessages` path.
- **Model override**: deployment-wide summary generation model selection
is split into #26803; the base feature always uses the chat model.

## Notes

- Migration `000540` adds `chats.summary` and
`chats.summary_generated_at`, and recreates `chats_expanded` to expose
the new columns.
- Root chats only; shared viewers pick up the summary on their next
refetch (live watch events are owner-only).

Michael Suchacz 3227cac217 feat: add manual chat compaction via /compact (#27081)
Adds a user-triggered `/compact` action for Coder Agents chats: typing
`/compact` in the composer (or picking it from the `/` trigger menu)
summarizes the conversation so far to free up context window space.

## How it works

- New `POST /api/experimental/chats/{chat}/compact` endpoint
(owner-only, RBAC `ActionUpdate`, excluded from the public API reference
via `x-apidocgen skip`). It marks the chat with a durable one-shot
`chats.compaction_requested_at` signal and moves it `waiting -> running`
via a new `RequestCompaction` state transition; no message row is
inserted. AI Gateway attribution needs no per-request key: generation
preparation resolves the owner's synthetic API key (#27170) like any
other turn.
- `RequestCompaction` hands off chat ownership (clears
`worker_id`/`runner_id`) so a worker acquisition hint is published;
since the transition changes no history, the previous runner could
otherwise miss the request under reordered pubsub delivery.
- The background chat worker picks the chat up like any other turn. A
pending manual request takes precedence over turn completion in the
generation decision, and forces compaction even below the automatic
threshold (and when compaction is disabled via threshold=100). The
commit step consumes the request marker in the same transaction; any
transition that ends the turn clears stale markers.
- The summary triplet reuses the automatic-compaction path, now tagged
with a `source` (`automatic` | `manual`) that is plumbed through
streamed progress parts, persisted tool JSON, and the UI label
("Summarized (manual)").
- Validation order: busy chats reject with 409 (state-machine conflict),
empty/already-compacted chats with 409 "nothing to compact", archived
chats with 400; the owner usage-limit check runs last so no-op requests
surface the specific conflict instead of a limit error.
- Web UI: the `/` trigger menu now has a built-in "Commands" group
listing `/compact`; submit intercepts exactly `/compact` and calls the
endpoint instead of sending a message. A personal or workspace skill
named `compact` takes precedence over the built-in command; while skill
collisions are still resolving, an exact `/compact` submission is
blocked with a retryable hint instead of leaking as message text.
History and queued-message edits are never intercepted. After
compaction, the context usage indicator resets to its unknown state
until the next assistant response reports fresh usage, instead of
showing the stale pre-compaction number.
- codersdk: `ExperimentalClient.CompactChat`.

Worker-path execution (rather than compacting synchronously in the
handler) reuses the existing lock fencing, live "Summarizing..."
streaming, retry accounting, restart resilience, and debug-run
observability. Rationale documented in `coderd/x/chatd/ARCHITECTURE.md`.

## Testing

- State machine: transition-matrix coverage for `RequestCompaction`,
marker lifecycle tests (carried by lease renewals/queue appends, cleared
by terminal transitions, consumed by commit), ownership handoff +
acquisition hint assertions.
- Worker: decision-ordering and forced-compaction unit tests;
active-server end-to-end test (manual compact below threshold produces a
`source=manual` summary, returns to `waiting`, no assistant follow-up;
busy chat rejected).
- API: success, archived, non-owner, RBAC-denied, empty-chat, no-daemon
cases; usage-limit ordering (at-limit owners still get
state/nothing-to-compact conflicts for no-op requests, with marker
rollback).
- Frontend: Storybook play tests for the Commands menu group, submit
intercept, skill-name collision, queued-edit passthrough, and
manual/automatic tool rendering; unit tests for command availability
resolution and the post-compaction context usage reset.

Michael Suchacz 4ed6fcced7 refactor(coderd): stop storing chat gateway key IDs and drop the columns (#27171)
> Mux is working on behalf of Mike.

## Summary

Stop reading and writing the legacy `api_key_id` columns on chat
messages and queued messages, and drop the columns in the same PR.
Runtime AI Gateway attribution continues to use the per-user synthetic
key introduced by #27170.

With the columns gone, `sqlc` generates `database.ChatMessage` and
`database.ChatQueuedMessage` without `api_key_id`, so no transitional
query scaffolding is needed.

Migration `000548` drops the `api_key_id` columns. #27170 already
removed their foreign keys, so the down migration re-adds nullable text
columns without constraints. Previous column values cannot be restored.

Also moves the model config validation in `CreateChat` above the
message-building work so a disabled or invalid model fails fast. On main
this mattered more: the old ordering minted a synthetic API key before
rejecting the request.

Deploy note: replicas still running the previous release write
`api_key_id` on insert, so chat message inserts on old replicas fail
during the rolling window after the column drop. This was previously
split across two PRs to avoid that window; per review feedback the split
added more churn than it was worth for an experimental surface.

Depends on #27170 (merged).

Michael Suchacz 46d1823c0a feat: add workspace skills to agent chat slash menu (#25600)
> This Pull Request was updated by Mux working on behalf of Mike.

Adds workspace skills to the agent chat slash menu, sourced entirely
from the chat's pinned context resources (the single-chat GET response
the page already fetches), the same inventory `read_skill` resolves
from. No new API endpoint is introduced.

Personal entries insert `/name`, or `/personal/name` when the name
collides with a workspace skill or the chat's pinned context has not
resolved yet; workspace entries insert `/workspace/name`. Qualified
aliases stay searchable even when the displayed trigger is bare. Before
a chat binds a workspace (new chat form, or a selected but unbound
workspace), the menu lists personal skills only.

Sending a message invalidates the chat detail query, and chatd
broadcasts a context watch event when a first-turn bind pins the chat,
so the menu picks up newly pinned context without a reload.

Makes `UpdateChatWorkspaceBinding` a no-op when the requested
workspace/build/agent binding is unchanged, preserving `updated_at` so
chat list ordering and watch events stay stable.

Includes regression coverage for the no-op binding guard, pinned-context
skill mapping, collision qualification, and skills menu behavior.

Michael Suchacz 6f6d7539c8 feat: remove unused chat statuses pending, paused, and completed (#27064)
The chatd state machine only recognizes `waiting`, `running`, `error`,
`requires_action`, and `interrupting`. Remove the unused `pending`,
`paused`, and `completed` values from the database enum, backend, SDK,
frontend, generated queries, and API docs.

Migration `000543_chat_status_remove_unused` remaps existing `pending`
rows to `running`, remaps `paused` and `completed` rows to `waiting`,
drops the obsolete `idx_chats_pending` index, and recreates
`chats_expanded` around the enum swap. It also removes the dead
`AcquireChats` query and all remaining query literals for the deleted
statuses.

**NOTE**: The enum swap can break chat queries from older replicas
during a mixed-version rollout because they still reference
`'pending'::chat_status`. Chats are experimental, so this PR accepts

Michael SuchaczandMathias Fredriksson 1eb5d579b0 fix: unblock manual chat title generation for unowned chats (#26963)
## Problem

The Generate button in the chat Rename dialog (POST
`/api/experimental/chats/{chat}/title/propose`) could fail in ways
unrelated to actual concurrent title generation:

- The manual title lock returned 409 for any `pending` chat and any
`running` chat without a worker. Legacy `pending` rows are never
acquired by workers, so those chats 409'd forever. Running chats are
unowned in the normal window between message submission and worker
acquisition (indefinitely when runners are down), producing spurious
409s.
- A missing default chat model config surfaced as a generic 500, and the
dialog hid the actionable cause carried in the error detail.

## Fix

Backend (`coderd/x/chatd`, `coderd`, `coderd/database`):

- Remove the manual title lock entirely. Races between title writers are
already resolved by `recordManualTitleUsage`, which re-reads the chat
under `GetChatByIDForUpdate` and only persists the generated title when
it is unchanged since the request snapshot, so concurrent regenerates
and renames settle by last write wins. The lock only suppressed
duplicate model calls (the dialog already disables the button in flight,
and usage limits bound spend), and its synthetic `worker_id` marker was
the source of the spurious 409s. The 409 responses, the marker and
staleness handling, and the now-unused
`UpdateChatStatusPreserveUpdatedAt` query are gone.
- New `ErrNoDefaultChatModelConfig` sentinel mapped to 400 "No default
chat model config is configured." in both title endpoints, matching the
POST `/chats` precedent.

Frontend (`site`):

- The Rename dialog error alert now renders the API error detail under
the message, reading `error.response.data.detail` directly so
detail-less API errors do not show the generic developer-console hint.
- Removed the dead regenerate-title UI plumbing (`onRegenerateTitle`
outlet wiring and the `regeneratingTitleChatIds` spinner pipeline). The
Rename dialog propose flow is the only live title-generation UX; the
endpoint, codersdk methods, and the `api.ts`/`queries/chats.ts` layer
are kept for API consumers.

## Tests

- chatd internal: a strict-mock test pinning the compare-and-swap guard
(a concurrently changed title must not be clobbered by a generated one),
plus the existing persist-and-broadcast coverage without lock
transactions.
- HTTP: `PendingWithoutWorker` expects 200 for both endpoints,
`NoDefaultModelConfig` (400) subtests, a stopped-workspace propose
regression, and an `Unauthenticated` propose subtest.
- Storybook: stories asserting the API error detail renders in the
dialog alert, and that detail-less API errors and plain errors do not
leak the developer-console hint.

Mathias Fredriksson 047c47495b refactor: drop chat_model_configs provider column (#26877)
The provider type already lives authoritatively in ai_providers.type,
reachable on every active row through ai_provider_id, which the
chat_model_configs_ai_provider_required_when_active CHECK makes
mandatory. The stored provider string was a denormalized copy the system
kept in sync with a startup backfill and no longer needs.

Every surface now derives provider type from the linked ai_providers
row. Telemetry is the one exception: it keeps emitting provider, now
sourced from ai_providers.type via a JOIN, so the BigQuery column and the
Nexus dashboards that read it are unaffected. The experimental HTTP/SDK
response drops provider and makes ai_provider_id required, since those
endpoints return only active configs; consumers resolve provider type
from ai_provider_id and the AI providers listing.

This ships in a single release with no compatibility window: production
reads the table via SELECT *, so a pre-drop binary fails config reads the
moment the column is gone. Operators must scale to zero before upgrading,
and there is no rollback.

Kyle Carberry cd56ab9e33 refactor: remove legacy live-read and injected-history chat context paths (#26585)
This PR makes the agent-pushed pinned snapshot
(`chat_context_resources`) the sole source of workspace context for
chats, completing the "Release 5" cleanup. It removes legacy mechanisms
now superseded by the snapshot that agents push over dRPC
(`PushContextState`) and refresh via `chat-context/refresh`.

Removed:

- **Live-read at turn time.** MCP tool discovery, skill live-body reads,
and the instruction/skill history fallback that dialed the workspace on
every turn.
- **Context injected as message history.** The
`persist_workspace_context` generation action and its decision-loop
guard.
- **The legacy write path.** `POST`/`DELETE
/api/v2/workspaceagents/me/experimental/chat-context`, the agentsdk
`AddChatContext`/`ClearChatContext` methods, and the CLI one-shot
writer.
- **The `chats.last_injected_context` column** and all of its plumbing
(migration `000529`, queries, `db2sdk`, `dbauthz`, audit table, and the
frontend `ContextUsageIndicator` fallback).

Subagent context inheritance no longer copies parent context messages;
children now hydrate the parent's pinned `chat_context_resources` on
create, which yields an identical pin for the same workspace and agent.

What stays (still served by the live agent connection, not the
snapshot): `read_skill_file` supporting-file reads, `read_skill`
supporting-file listing, and MCP tool execution.

> [!NOTE]
> Migration `000529` drops `chats.last_injected_context` and recreates
the `chats_expanded` view without it. The down migration restores both.

<details>
<summary>Decision log (D1-D5)</summary>

- **D1 (subagent inheritance):** Re-point inheritance from the legacy
message copy to a pinned hydrate. Children call
`hydrateChatContextOnCreate` instead of copying parent context messages.
- **D2 (`persist_workspace_context`):** Remove the generation action
entirely along with the decision-loop guard it existed to satisfy, since
context is never injected into history anymore.
- **D3 (legacy HTTP + CLI):** Remove the experimental `chat-context`
POST/DELETE endpoints, the agentsdk methods, and the CLI one-shot. The
dRPC push + `chat-context/refresh` replace them.
- **D4 (frontend fallback):** Remove the `last_injected_context`
fallback in `ContextUsageIndicator`; pinned `resources` are the sole
source.
- **D5 (sequencing):** Ship as a single PR rather than a stacked pair.

Kyle Carberry 1c78bd84b7 feat(coderd): copy agent context resources into the per-chat pin (#26438)
## What

Populates `chat_context_resources` (the per-chat pinned copy added in
#26430) by copying from `workspace_agent_context_resources` at the
points where a chat's `context_aggregate_hash` is set, in the same
transaction, so the pinned hash and pinned bodies always agree. No
prompt-building change yet; consuming the pinned copy in
`prepareGeneration` is a later, experiment-gated PR.

## How

- `HydrateAgentChatsContext` now hydrates NULL-hash chats **and** copies
the agent's resources onto them in one statement (a data-modifying CTE),
so the chat-create and agent-push paths need no Go change.
- New queries `InsertAgentContextResourcesIntoChat`,
`DeleteChatContextResources`, `ListChatContextResources`, each with a
hand-written dbauthz wrapper (per-chat update/read) and a
`MethodTestSuite` entry.
- `RefreshChatContext` re-pins resources via a shared `repinChatContext`
helper (clear-then-copy in a transaction). A dirty chat keeps its old
bodies until refresh.
- On agent rebind (e.g. a workspace rebuild produces a new agent), the
chat's context is re-pinned to the new agent so it stops injecting the
previous agent's resources. Best-effort: a context error never fails the
binding.

## Invariant

A chat's `chat_context_resources` always correspond to its
`context_aggregate_hash`. Bodies are (re)written only when the hash is
set (hydrate, refresh, rebind); a dirty chat keeps its old bodies until
refresh.

## Testing

Extends the context integration test to push real resources and assert
the copy across hydrate, dirty (no re-copy), and refresh. The dbauthz
`MethodTestSuite` covers the three new methods.

<details>
<summary>Why clear-then-copy (two statements)</summary>

The refresh/rebind re-pin clears the chat's rows then inserts the
agent's. It uses two sequential statements inside the transaction rather
than a single `WITH cleared AS (DELETE ...) INSERT ...`, because a
data-modifying CTE cannot see its own delete under snapshot isolation,
so overlapping sources (the common case: the same files re-pinned) would
collide on the `(chat_id, source)` primary key. The hydrate path inserts
into never-pinned (NULL-hash) chats and uses `ON CONFLICT DO UPDATE`
defensively.

</details>

<details>
<summary>Follow-ups</summary>

- `prepareGeneration` consuming the pinned instructions and skills
(experiment-gated).
- `codersdk.ChatContext` resources plus changed diff, and the frontend
indicator/refresh.
- Removing the per-turn pull and `last_injected_context`.

</details>

Kyle Carberry 53a6459ecd feat(coderd/database): add chat_context_resources table (#26430)
Adds chat_context_resources: a per-chat pinned copy of the agent context
resources a chat is hydrated against. The agent-side table
(workspace_agent_context_resources) is last-writer-wins with no history,
so a chat copies its resources at hydration/refresh to keep a stable view
while the agent drifts.

Schema foundation only (no queries/dbauthz/prepareGeneration/SDK yet).
chat_id FK ON DELETE CASCADE for cleanup parity; no agent FK so the pin
survives agent replacement; PK (chat_id, source); reuses the 000522 enum
types.

Kyle Carberry 210261b143 feat: add chat context pinning storage and push trigger (#26385)
Foundation for the Workspace Context Sources RFC (phase 3). The agent
push (#25983) and coderd snapshot storage (#26145) already persist
per-agent context snapshots; this PR lands the **chat-side storage**
plus the **`agentapi` push trigger** that a follow-up will use to read
them. It does **not** touch `chatd` and changes no behavior — nothing
wires an implementation yet.

## What changed

- Adds four nullable columns to `chats` — `context_aggregate_hash`,
`context_dirty_since`, `context_dirty_resources`, and `context_error` —
and rebuilds the `chats_expanded` view.
- Adds three queries — `SetChatContextSnapshot`,
`HydrateAgentChatsContext`, `MarkChatsContextDirtyByAgent` — with
`dbauthz` wrappers and `audit` entries. They are store-interface methods
covered by a Postgres test (`TestChatContextHydration`).
- Adds the `agentapi.ContextDirtyMarker` interface and invokes it inside
the `PushContextState` transaction, publishing collected events only
after commit.

## Intentionally inert

There are **no production callers** of the three queries and **no
implementation** wired for `ContextDirtyMarker`, so the push trigger is
dormant. This is deliberate: the PR is the durable storage/query
foundation only.

The actual integration — the `chatd` implementation that
hydrates/dirties chats and backs a refresh endpoint, consuming the
pinned context in prompt building, the rich SDK types + UI, and retiring
the live per-turn pull — lands as a single follow-up PR. Splitting this
way keeps the schema/query layer reviewable on its own and keeps the
integration whole in one place.

Refs #25983, #26145.

<details>
<summary>Decision log</summary>

- **Columns over a side table.** The four `chats` columns are the
durable model (accepting the one-time `chats_expanded` view/CTE churn).
`last_injected_context` is deliberately left untouched — it is
load-bearing for the live per-turn context pull.
- **Keep `agentapi`, drop `chatd`.** The earlier revision wired the
hydrate/dirty implementation through `chatd` and added a `PUT
/chats/{chat}/context` refresh endpoint. Those were removed so this PR
is pure foundation; `agentapi` defines the trigger + interface (it does
not import `chatd`), and the `chatd` implementation arrives with the
full integration.
- **No new experiment flag.** The columns are dark and unread by prompt
building.
- **Authz.** The new query wrappers authorize chat updates under the
chat RBAC object / `ResourceChat`, consistent with the existing system
chat mutators.

Michael Suchacz 8b1705eb65 feat: route chatd provider traffic through aibridge (#25629)
## Summary

Routes chatd model calls backed by concrete AI Provider rows through the
in-process aibridge transport by default, with deployment options to use
direct provider routing when AI Gateway is disabled or chat AI Gateway
routing is disabled.

- Splits model routing into common, direct provider, and AI Gateway
paths behind a single deployment-mode entry point.
- Builds chatd models through explicit request, route, and options data.
Active API key attribution is passed explicitly instead of being hidden
inside generic model construction.
- For AI Gateway BYOK routes, resolves the user's provider key in chatd,
forwards it through provider-specific auth headers, and sets
`X-Coder-AI-Governance-Token` to the `delegated` marker so aibridge
preserves those headers while still stripping Coder-specific metadata.
- Keeps central provider credentials and deployment fallback credentials
out of forwarded provider auth headers, so AI Gateway central policy
remains authoritative.
- Redacts delegated provider auth from default string formatting to
avoid accidental plaintext logging of user BYOK credentials.
- Covers selected chat models, advisor overrides, title and quickgen
paths, subagent overrides, computer use model selection, and an
integration-style chat turn through the aibridge transport path.
- Persists initiating API key IDs on chat and queued user messages,
including subagent child messages, and fails closed for AI
Gateway-routed model builds without an active key.
- Removes unused `api_key_id` indexes while keeping the persistence
columns and foreign keys.
- Keeps the deployment option available through config and env parsing,
but hides it from CLI help and generated docs.
- Stabilizes the subagent poll fallback test so background CreateChat
processing cannot win the state transition under slower CI environments.

Cian Johnston c8b1fa3196 fix: use UTC day boundaries for chat auto-archive eligibility (#25597)
Fixes CODAGT-311.

Users receive too many auto-archive notification emails because the
dbpurge loop runs every 10 minutes and archives chats on each tick using
timestamp-precise cutoffs, causing chats to trickle past the threshold
continuously.

Switch archive eligibility from timestamp arithmetic to date arithmetic
(UTC day boundaries). All chats whose last activity falls on the same
UTC date are now archived together on the first tick after midnight UTC,
reducing notification emails to ~at most~ probably one per day.
(Exception: if we hit the auto-archive limit)

- SQL compares `(last_activity AT TIME ZONE 'UTC')::date` against cutoff
date
- Go truncates current time to start-of-day before subtracting archive
days
- Tests verify date boundary semantics including late-activity and batch
edge cases
- Docs updated to describe UTC day boundary behavior and at-most-daily
notification cadence

Michael Suchacz cb37047dce feat: dedicated /prompts endpoint for chat history cycle (#25083)
Follow-up to #25004. The merged change cycles only through messages
already loaded in the in-memory chat store (page size 50). Long chats
and chats whose oldest turns have rolled out of the page lose access to
their earlier prompts in the composer's up/down arrow cycle. This PR
adds a dedicated server endpoint that returns the full prompt history,
newest first, and rewires the composer to use it.

## What changed

### Endpoint

`GET /api/experimental/chats/{chat}/prompts?limit=N`

```go
type ChatPrompt struct { ID int64; Text string }
type ChatPromptsResponse struct { Prompts []ChatPrompt }
```

- `limit`: `0..2000`. `0` (the default) is treated as the server-side
default of 500; out-of-range values return `400`. Negative values are
rejected by the SDK's `PositiveInt32` parser before reaching the
handler.
- Auth: parent-chat read in `dbauthz`, mirroring
`GetChatMessagesByChatID`.
- The SQL filters `role='user'`, `deleted=false`, `visibility IN
('user','both')`, guards the lateral with `jsonb_typeof(content) =
'array'` so legacy V0 scalar-string rows are silently skipped, then
unrolls `content` JSONB with `WITH ORDINALITY` and concatenates only
`type='text'` parts in original order via `string_agg(... ORDER BY
ordinality)`. Messages whose joined text is whitespace-only are dropped
via `HAVING ... ~ '\S'` so cycling never lands on a blank entry.

### Partial index (migration `000494`)

```sql
CREATE INDEX idx_chat_messages_user_prompts
ON chat_messages (chat_id, id DESC)
WHERE deleted = false
  AND role = 'user'
  AND visibility IN ('user', 'both');
```

The partial WHERE matches the query's filter exactly and the key order
matches `ORDER BY id DESC`, so the planner gets both the filter and the
ordering from the index without a sort step.

`EXPLAIN ANALYZE` on a synthetic 51-chat × 5,000-message dataset (≈260k
rows, 10k user prompts in the target chat, `random_page_cost=1.1`):

| | Plan | Buffers hit | Time |
|---|---|---|---|
| Without index | `Index Scan Backward using chat_messages_pkey`,
**250,848 rows removed by filter** | 6,683 | 32.4 ms |
| With index | `Index Scan using idx_chat_messages_user_prompts`, no
filter | 38 | 1.3 ms |

≈25× faster, 175× fewer buffer hits.

### Frontend

- `chatPromptsKey` / `chatPromptsQuery` factories in
`site/src/api/queries/chats.ts` (`staleTime: 30s`, `enabled: chatId !==
""`, asks the server for 500 prompts).
- `ChatPageContent.tsx` replaces the in-memory derivation with
`useQuery(chatPromptsQuery(chatId ?? ""))`. The composer's existing
`cycleHistorySnapshotRef` anchors the in-flight cycle so a refetch
arriving mid-cycle cannot shift the indexed prompt out from under the
user.
- `getEditableUserMessagePayload` now concatenates user-message text
parts verbatim, mirroring the server's `string_agg(part->>'text', ''
ORDER BY ordinality)`, instead of routing through the streaming-oriented
`parseMessageContent` / `appendText` pipeline (which drops
whitespace-only chunks — correct for assistant streams, wrong for a
user's persisted message). This keeps the cycle and the edit path in
agreement on the same message. File blocks are still pulled separately
via
`parseMessageContent(...).blocks.filter(isEditableUserMessageFileBlock)`.
- Cache invalidation in `createChatMessage.onSuccess`,
`editChatMessage.onSettled`, and `useChatStore.upsertCacheMessages`
(only when an upserted message has `role === "user"`).
- Page-level stories pre-seed `chatPromptsKey(CHAT_ID)` from the same
`messagesData` to keep them offline.

## Tests

- New `TestGetChatUserPrompts` in `coderd/exp_chats_test.go` with five
subtests:
- `NewestFirstFiltering` — multi-part concatenation, non-text parts
skipped, whitespace-only filtered, soft-deleted excluded, `model`-only
visibility excluded, assistant-role excluded by `cm.role = 'user'`,
legacy V0 scalar row silently excluded by the `jsonb_typeof` guard,
ordering newest first.
- `LimitClampsResults` — explicit `limit=2` returns the two newest
prompts.
  - `InvalidLimitRejected` — `limit=5000` is `400 Bad Request`.
- `NotFoundForOtherUsers` — a separate user in the same org gets `404`,
not the prompts.
- `EmptyResultIsJSONArray` — zero-message chat and assistant-only chat
both return `Prompts: []` (non-nil, empty).
- New unit test in `messageParsing.test.ts` asserting that
`getEditableUserMessagePayload(["hello", " ", "world"])` returns `"hello
world"`, locking in the agreement with the SQL `string_agg`.
- `dbauthz_test.go` adds the
`MethodTestSuite.TestChats/GetChatUserPromptsByChatID` entry, asserting
parent-chat `policy.ActionRead`.
- `pnpm test src/pages/AgentsPage` — 1159 passed, 2 skipped.
- `make gen` produces no diff.

## Manual verification

Seeded a dev chat with Claude Sonnet 4.6 via the aibridge Anthropic
provider and posted 20 user prompts end-to-end. Verified that the
`/prompts` endpoint returns 20 rows newest-first, that `limit=10` clamps
correctly, that `limit=0` uses the server default of 500, and that the
up/down keyboard cycle in the composer walks the same sequence (and
reverses correctly back to the empty draft).

## Out of scope

- Cross-chat history.
- Per-user opt-out for the cycle.
- File-reference / attachment cycling — the cycle continues to reproduce
plain text only, by design.

<summary>Implementation plan</summary>

# CODAGT-319 Follow-up — Dedicated `/prompts` endpoint

## Context

The merged feature ([#25004](https://github.com/coder/coder/pull/25004)
/ [d32842f](https://github.com/coder/coder/commit/d32842f)) cycles only
through messages already loaded in the in-memory chat store, which is
capped at the first 50 messages of the current page. Long chats and
chats whose oldest turns have rolled out of the page can no longer
recall their full prompt history. This follow-up exposes a dedicated
server endpoint that returns the user-authored prompts in a chat, newest
first, and rewires the composer to use it.

## Design

### Endpoint

`GET /api/experimental/chats/{chat}/prompts?limit=N`

Returns:

```go
type ChatPrompt struct {
    ID   int64
    Text string
}
type ChatPromptsResponse struct {
    Prompts []ChatPrompt
}
```

- `limit`: `0..2000`. `0` (the default) → server-side default of 500.
The wire-level default is encoded in SQL as `COALESCE(NULLIF($limit, 0),
500)`. Negatives are rejected upstream by `PositiveInt32`; the handler
only caps the upper bound.
- Auth: parent-chat read in `dbauthz`, mirroring
`GetChatMessagesByChatID`.
- Listed under the experimental router so we can iterate without API
guarantees.

### SQL

The query lives in `coderd/database/queries/chats.sql` as
`GetChatUserPromptsByChatID`:

- Filters `role='user'`, `deleted=false`, `visibility IN
('user','both')` to mirror the composer's "what the user actually typed
and can re-send" contract.
- Guards the lateral with `jsonb_typeof(content) = 'array'` so legacy V0
rows whose content is a scalar JSON string (predates migration `000434`)
are silently excluded instead of raising `"cannot extract elements from
a scalar"`.
- Unrolls `content` JSONB with `jsonb_array_elements WITH ORDINALITY`
and concatenates only `type='text'` parts, preserving original order via
`string_agg(... ORDER BY ordinality)`.
- Casts the result to `text` so sqlc emits a `string` field instead of
`[]byte`.
- Drops whitespace-only prompts via `HAVING string_agg(...) ~ '\S'` so
cycling never lands on a blank entry.
- Orders by `cm.id DESC` (`id` is a sequence, so this is "newest first"
without relying on `created_at`).

### Index

New partial index added in migration `000494`:

```sql
CREATE INDEX idx_chat_messages_user_prompts
ON chat_messages (chat_id, id DESC)
WHERE deleted = false
  AND role = 'user'
  AND visibility IN ('user', 'both');
```

The partial WHERE clause matches the query's filter exactly, so the
planner can use the index for both filtering and ordering without a sort
step.

### Frontend

- `chatPromptsKey(chatId)` and `chatPromptsQuery(chatId)` factories in
`site/src/api/queries/chats.ts`. `staleTime: 30s`, `enabled: chatId !==
""`. Asks the server for 500 prompts (well below the 2000 max, plenty
for the cycle).
- `ChatPageContent.tsx` replaces the in-memory derivation with
`useQuery(chatPromptsQuery(chatId ?? ""))`. The composer's
`cycleHistorySnapshotRef` already takes a stable snapshot at cycle
entry, so a refetch arriving mid-cycle cannot shift the indexed prompt
out from under the user.
- `getEditableUserMessagePayload` extracts the edit-path text from raw
user-message parts (filter `type === "text"`, join verbatim) instead of
going through `parseMessageContent` / `appendText`, which is built for
assistant streams and intentionally drops whitespace-only chunks.
Without this, cycling and clicking Edit on the same message could
produce different draft text for messages with whitespace-only
interleaved text parts.
- Cache invalidation: `createChatMessage.onSuccess`,
`editChatMessage.onSettled`, and `useChatStore.upsertCacheMessages`
(when at least one upserted message has `role === "user"`) all
invalidate `chatPromptsKey(chatId)`.

### Tests

- `TestGetChatUserPrompts` (`coderd/exp_chats_test.go`) covers:
- `NewestFirstFiltering` — multi-part concatenation, non-text parts
skipped, whitespace-only filtered, soft-deleted excluded, `model`-only
visibility excluded, assistant-role excluded by `cm.role = 'user'`,
legacy V0 scalar row silently excluded by the `jsonb_typeof` guard,
ordering newest first.
- `LimitClampsResults` — explicit `limit=2` returns the two newest
prompts.
  - `InvalidLimitRejected` — `limit=5000` is `400 Bad Request`.
- `NotFoundForOtherUsers` — a separate user in the same org gets `404`,
not the prompts.
- `EmptyResultIsJSONArray` — zero-message chat and assistant-only chat
both return `Prompts: []` (non-nil, empty).
- `messageParsing.test.ts` adds a unit test asserting that
`getEditableUserMessagePayload(["hello", " ", "world"])` returns `"hello
world"`, locking in the agreement with the SQL `string_agg`.
- `dbauthz_test.go` adds the
`MethodTestSuite.TestChats/GetChatUserPromptsByChatID` entry, asserting
the parent-chat `policy.ActionRead`.

## Out of scope

- Cross-chat history.
- Per-user opt-out for the cycle.
- File-reference / attachment cycling — the cycle still reproduces plain
text only, by design.

Kyle Carberry 5040ab6fca feat: filter chats by diff URL via the q search parameter (#24970)
Adds a `diff_url:` term to the `q` search parameter on `GET
/api/experimental/chats` so callers can look up the chat associated with
a particular pull request, merge request, or any other URL persisted on
the chat's diff status.

```
q=diff_url:"https://github.com/coder/coder/pull/123"
```

Match is case-insensitive. When the URL lives on a delegated sub-agent's
diff status, the parent chat is returned so the relationship surfaces
from a single lookup.

<details>
<summary>Design notes</summary>

- **Forge-agnostic.** Reuses the existing `chat_diff_statuses.url`
column rather than introducing a `pr:` vocabulary, since the SDK already
documents the URL as "may point to a pull request or a branch page
depending on whether a PR has been opened." Works for GitHub PRs, GitLab
MRs, branch pages, etc.
- **Composes with `archived:`.** The two terms can be combined:
`q=archived:true diff_url:"..."`.
- **Case handling.** The parser used to lowercase the entire `q` string
up front, which would mangle URL path segments. Switched to lowercasing
only the field key inside `searchTerms` (already happens there) and
keeping the value as the caller typed it. The SQL comparison lowercases
on both sides.
- **Validation.** `diff_url` must be a syntactically valid HTTP(S) URL
with a non-empty host. No forge-specific validation.
- **Index.** Adds `idx_chat_diff_statuses_url_lower` on `LOWER(url)` so
the lookup is cheap even on large datasets.
- **Sub-agent fan-in.** `EXISTS` clause matches when the URL lives on
the chat itself or any chat with `root_chat_id` equal to the chat's id,
so a delegated sub-agent's PR pulls in its parent.
- **Deferred.** Sentinels like `pr:any` / `pr:none` and a forge-agnostic
state filter (`diff_state:open|merged|closed`) were intentionally left
out of this change. They couple cleanly to a second forge or a clearer
product call, and shipping them now would lock in vocabulary we may want
to revisit.

</details>

## Tests

- `coderd/searchquery`: parser tests for valid URLs, case handling (key
insensitive, value preserved), composition with `archived:`, and
validation errors (non-HTTP scheme, missing host, malformed URL).
- `coderd/exp_chats_test.go`: end-to-end coverage hitting `ListChats`.
Verifies a root chat matches its own URL, a parent chat surfaces when
only a sub-agent has the URL, lookups are case-insensitive, non-matching
URLs return empty, and invalid URLs return `400`.

Michael Suchacz 0bfb9f6f13 feat: show agent turn summary in agents sidebar (#24942)
Persists the agent-generated turn-end summary on `chats` and shows it as
the Agents sidebar subtitle when present, falling back to the model
name. Errors still take precedence.

> Mux is acting on Mike's behalf.

## What changes

**Storage.** New nullable `last_turn_summary` column on `chats`
(migration `000486`). New `UpdateChatLastTurnSummary` query normalizes
blank/whitespace input to `NULL`, preserves `updated_at` (so the chat
does not jump to the top of the sidebar on summary writes), and uses an
`expected_updated_at` stale-write guard so an older async summary cannot
overwrite a newer turn.

**Backend.** `coderd/x/chatd/chatd.go` decouples summary generation from
webpush. Generated summaries persist for completed parent turns even
when webpush is unconfigured or has no subscriptions. The same generated
text is reused as the webpush body when webpush is configured, so the
summary model is not called twice. Generic fallback push text is no
longer persisted; it clears any stale summary instead.
Error/interrupt/pending-action terminal paths clear `last_turn_summary`
for the latest turn.

**Frontend.** `AgentsSidebar.tsx` subtitle priority is now `errorReason
|| lastTurnSummary || modelName`, normalized via the existing
`asNonEmptyString` helper from `blockUtils.ts`.

## Tests

- `TestUpdateChatLastTurnSummary` (database): success,
whitespace-to-NULL, stale guard rejects, `updated_at` preserved.
- `TestUpdateLastTurnSummaryRejectsStaleWrites` (chatd internal): direct
stale-`expected_updated_at` test.
- `TestSuccessfulChatPersistsTurnSummaryWithoutWebPush`: persistence
works without webpush subscriptions.
- `TestSuccessfulChatSendsWebPushWithSummary`: same generated text
drives both DB and push body.
-
`TestSuccessfulChatSendsWebPushFallbackWithoutSummaryForEmptyAssistantText`:
fallback text is not persisted.
- `TestErroredChatClearsLastTurnSummaryAndSendsWebPush`: error path
clears the field.
- `TestInterruptChatDoesNotSendWebPushNotification`: interrupt path
clears the field, no push fires.
- `AgentsSidebar.test.tsx`: subtitle priority for summary-present,
error-wins, no-summary fallback, whitespace fallback.
- `AgentsSidebar.stories.tsx`: `ChatWithTurnSummary` and
`ChatWithTurnSummaryAndError`.

## Notes

- No backfill. Existing chats keep showing the model name until their
next turn completes.
- Parent chats only in this iteration; the field is rendered on any
`Chat` if a future change extends generation to children.
- Decoupling generation from webpush adds quickgen model calls for
completed parent turns that previously skipped generation when no
subscriptions existed. Existing parent-only, assistant-text-present,
`PushSummaryModel` configured, and bounded-timeout gates keep this
behavior bounded.

Ethan 4751416b29 fix!: persist structured chat errors (#24919)
**Breaking change for changelog:**

> `codersdk.Chat.last_error` now returns a structured `ChatError` object
(`{message, kind, provider, retryable, status_code, detail}`) instead of
a plain string. The chats API is experimental
(`/api/experimental/chats`), so this ships without a deprecation cycle;
consumers reading `chat.last_error` as a string must update to read
`chat.last_error.message`. SDK/generated TypeScript terminal error
payloads now use the single `ChatError` type; the live stream error
payload type is renamed from `ChatStreamError` to `ChatError`.

Persisted chat errors now carry the same provider-specific detail (kind,
provider, retryable, HTTP status, optional detail) as the live stream,
so refreshing a failed chat rehydrates with the full structured error
instead of a one-line headline.

Existing rows are migrated in place: legacy text errors are wrapped into
`{message, kind: "generic"}` so already-errored chats still render, and
rows with `last_error IS NULL` stay NULL. Internally, persisted fallback
decoding now reuses the existing `chaterror.KindGeneric` constant, with
no JSON value change.

Cian Johnston 70d6efa311 feat: chat auto-archive owner digest notifications (#24643)
Depends on #24642

Adds per-owner digest notifications onto the chat auto-archive
subsystem.

Each tick's archived rows are grouped by owner, the top 25 titles per
owner are rendered into a new `Chats Auto-Archived` notification
template, and any remainder surfaces as `and N more`. Each digest is
per-tick, so users with large amounts of purgeable data may get multiple
notifications in sequence (one per user per tick).

The template body branches on `retention_days`: when retention is
disabled (`retention_days=0`), users are told archived chats are kept
indefinitely rather than falsely claiming imminent deletion.

### Changes
- migration `000XXX_chat_auto_archive_notification_template` adds new
notification template
- `dbpurge`: threads `notifications.Enqueuer` through `New`; and
enqueues notification message.
- `cli/server.go`: passes `options.NotificationsEnqueuer` into
`dbpurge.New`.
- `coderd/notifications/events.go`: new `TemplateChatAutoArchiveDigest`
UUID.
- `coderd/inboxnotifications.go`: inbox registration.
- Docs: adds a `Notifications` section to `chat-auto-archive.md`.

Michael Suchacz c7cac9debe fix: persist per-turn model on chats and queued messages (#24688)
Previously, `chats.last_model_config_id` was not updated when a user
sent a mid-chat message with a different model, and queued messages did
not store their own per-turn model, so promotion ran against whatever
the chat row said at promote time. Chat watch events also did not merge
`last_model_config_id` into the site's root, child, and per-chat
caches, so sidebar labels stayed stale after direct sends and queued
promotions.

- Add nullable `chat_queued_messages.model_config_id`, backfilled from
  `chats.last_model_config_id`. Queued inserts round-trip the effective
  model id at enqueue time.
- In `coderd/x/chatd`, direct sends update `chats.last_model_config_id`
  inside the same transaction that inserts the admitted user message.
  Manual promotion and auto-promotion use the queued row's stored
  `model_config_id`, with a fallback to `chats.last_model_config_id`
for legacy NULL rows during rollout.
`PromoteQueuedOptions.ModelConfigID`
  is now ignored.
- On the site, extract `mergeWatchedChatSummary` and
  `mergeWatchedChatIntoCaches` in `site/src/api/queries/chats.ts` so
  status-change watch events merge `last_model_config_id` into the
  root infinite chat list, the parent-embedded child entry, and the
  per-chat `chatKey(chatId)` cache. `updated_at` guards against stale
  watch payloads clobbering newer cached state, while diff status
  events still merge their PR metadata because they are timestamped
  outside the chat row. Watch timestamps are compared as instants so
  variable fractional precision does not make fresh events look stale.
- Queued promotion validates stored model config IDs before admission.
  Invalid legacy queued IDs fall back to the chat's current model config
  instead of dropping the queued message during auto-promotion.
- Backend and frontend regression coverage added for admission, queue
  promotion (including FIFO across mixed models, legacy NULL fallback,
  and invalid queued model IDs), and chat watch cache merging.

Mathias Fredriksson f8fe5d680b fix(coderd): reject API operations on archived chats (#24633)
Archived chats accept mutations (messages, edits, queued-message
promotions, tool-result submissions) via the API, causing them to
re-enter the processing pipeline. This violates the hard-stop
design intent from PR #23758.

Add archived checks at three layers:

- HTTP handlers (postChatMessages, patchChatMessage,
  promoteChatQueuedMessage, postChatToolResults): return 400
  after auth so callers get a clear error.
- Daemon functions (SendMessage, EditMessage, PromoteQueued,
  SubmitToolResults): return ErrChatArchived after row lock,
  guarding against future callers that bypass the handler.
- AcquireChats SQL: filter out archived chats so they are never
  acquired for processing.

Mathias Fredriksson 467430d8fa fix: sort child chats newest-first and prepend on creation (#24524)
GetChildChatsByParentIDs sorted created_at ASC, but the cache
helper appended new children to the end. On refetch the API and
cache agreed on oldest-first, putting the just-created child at
the bottom. Users expect newest first, matching the root-chat
sidebar convention.

- SQL: change child sort to created_at DESC, id DESC.
- Cache: prepend instead of append in addChildToParentInCache
  (renamed from appendChildToParentInCache to avoid leaking
  position semantics).
- Test: update ordering assertion to expect newest-first.

Mathias Fredriksson fc2493780f fix: exclude subagent chats from sidebar pagination (#24404)
GetChats now returns only root chats (parent_chat_id IS NULL).
A new GetChildChatsByParentIDs query fetches children for visible
roots and embeds them in each parent's Children field. The
singular getChat endpoint does the same.

Archive invariant is one-way: parent archived implies child
archived. Parent archive/unarchive cascades via root_chat_id.
Individual child archive is permitted; child unarchive while the
parent is archived is rejected atomically (row lock on child,
re-read parent inside the transaction). Embedded children are
filtered by the caller's archive state so individually-archived
children stay hidden from active-parent views.

Gitsync MarkStale uses GetChatsByWorkspaceIDs directly;
MarkStaleParams.OwnerID removed (dead after the switch).

Frontend: buildChatTree reads from the embedded children field,
WebSocket handlers route child events into the parent's children
array, and archiving a child strips it from the parent cache.

Dean Sheather 4ba74dcdc8 feat(coderd): add PR status summary to telemetry snapshots (#24379)
Adds aggregate PR counts (total, open, merged, closed) from
`chat_diff_statuses` to telemetry snapshots, giving visibility into AI
agent PR outcomes across deployments.

The existing telemetry system reports `Chats`, `ChatMessageSummaries`,

collected via a parallel `eg.Go()` block in `createSnapshot()`.
- `dbauthz` wrapper uses `rbac.ResourceSystem` (telemetry-only pattern).

Dean Sheather 3452ab3166 chore: add client_type field to chats and telemetry (#24342)
Add a `chat_client_type` enum (`ui` | `api`) and `client_type` column to
the `chats` table. The column defaults to `api` for new rows so API
callers don't need to set it explicitly. Existing rows are backfilled to
`ui`.

The field flows through `CreateChatRequest`, `chatd.CreateOptions`,
`InsertChat`, and is returned in the `Chat` response via `db2sdk`.

<details>
<summary>Implementation notes (Coder Agents generated)</summary>

### Changes

**Database migration (000469)**
- New enum `chat_client_type` with values `ui`, `api`.
- New `client_type` column, `NOT NULL DEFAULT 'api'`.
- Backfill: `UPDATE chats SET client_type = 'ui'`.

**SQL query** — `InsertChat` now includes `client_type`.

**SDK** — `ChatClientType` type added; `ClientType` field added to both
`CreateChatRequest` (optional, defaults server-side to `api`) and `Chat`
response.

**Handler** — `postChats` maps the request field (defaulting to `api`)
and passes it through `chatd.CreateOptions`.

**Sub-agent** — Child chats inherit their parent's `client_type`.

**db2sdk** — Maps the database value to the SDK type.

### Decision log
- Default is `api` (not `ui`) so existing API integrations get the
correct value without code changes.
- Backfill sets existing rows to `ui` per requirement.
- Child chats inherit `client_type` from parent rather than defaulting.

- Update dbauthz wrappers for new param structs
- HTTP endpoints (`chatCostSummary`, `getMyChatUsageLimitStatus`) pass
`uuid.Nil` with TODO for future org-scoped UI

columns DESC so the cursor tuple < comparison still works. Update
