chore: bump version to 1.4.0

Repo previously had no CHANGELOG.  Establishes the file with full
1.4.0 coverage (attachments end-to-end, dashboard composer refactor,
Slack adapter, per-call plan/task model, provider capability
passthrough, Opus 4.7) plus a one-line 1.3.1 entry for the Opus 4.7
backport.  Format follows Keep a Changelog 1.1.0; release-track
guidance up top covers the three stable branches + main.

Operator-relevant call-out at the top of [1.4.0]: migrations 037 +
038 must be applied before starting 1.4.0 against an existing 1.3.x
database.  Both are additive and idempotent.

+# Changelog
+
+All notable changes to turnstone are documented here.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [PEP 440](https://peps.python.org/pep-0440/) for
+version numbers (`X.Y.Z`, with `X.Y.ZaN` / `bN` / `rcN` for pre-releases).
+
+Three release tracks are maintained:
+
+- **`stable/1.0`** — patch-only (`v1.0.x`)
+- **`stable/1.3`** — patch-only (`v1.3.x`)
+- **`stable/1.4`** — patch-only (`v1.4.x`)
+- **`main`** — experimental (`v1.5.0aN`)
+
+## [Unreleased]
+
+## [1.4.0]
+
+User-visible additions: a full attachment system (images + text documents,
+including pre-creation uploads), a unified dashboard composer, a Slack
+channel adapter, per-call plan/task model selection with an admin UI, and
+provider capability passthrough.
+
+This release introduces two forward-only schema migrations
+(`037_workstream_attachments`, `038_workstream_attachments_reserved_at`)
+that the server applies automatically on first startup against an
+existing 1.3.x database.  Both are additive; no data loss.  See
+**Database migrations** below for details.
+
+### Added
+
+- **Workstream attachments** — images (png/jpeg/gif/webp, 4 MiB cap) and
+  text documents (any `text/*` MIME, allowlisted application MIMEs, or
+  known text extensions; 512 KiB cap; UTF-8 enforced).  Magic-byte image
+  sniffing on upload; per-(ws, user) pending cap of 10.  Three-state
+  lifecycle (`pending → reserved → consumed`) with reservation tokens
+  threaded through `/v1/api/send` so queued multimodal turns can't lose
+  files to overlapping sends.  Provider-side translation: Anthropic
+  emits native document blocks; OpenAI Chat Completions inlines them as
+  escaped `<document>` text blocks; Responses API emits `input_text`
+  with the same wrapper. (#356)
+- **Attachments at workstream-creation time** —
+  `POST /v1/api/workstreams/new` accepts `multipart/form-data` (one
+  `meta` JSON field plus 0..N `file` parts).  Files are validated and
+  reserved onto the first turn before the dispatch worker fires; failure
+  rolls back the fresh workstream so no orphan rows leak.  Web UI
+  (new-workstream modal + dashboard composer), Python SDK, and
+  TypeScript SDK all gained attachment support.  Cluster routing
+  (`/v1/api/route/workstreams/{ws_id}/attachments`) extended to forward
+  multipart bodies + preserve upstream headers (CSP, Content-Disposition).
+  SDKs auto-generate `ws_id` client-side so cluster-routed callers can
+  bind the body to the owning node before it lands. (#362)
+- **Slack channel adapter** (Socket Mode) — mirrors the Discord adapter:
+  per-user channel sessions via configurable slash command, DM routing,
+  SSE event consumption, tool approval buttons (with per-user owner
+  enforcement), plan-review approve / request-changes modal,
+  notification reply routing back into the workstream, session recovery
+  after restart.  Install with `pip install 'turnstone[slack]'`. (#355)
+- **Console admin UX support for Slack** — channel-link modal offers
+  Slack alongside Discord; skill notify-on-complete forms expose a
+  per-row channel-type dropdown (and no longer hardcode `discord`);
+  per-platform `.scope-discord` / `.scope-slack` badge classes with
+  theme-aware tokens (`--discord` / `--slack`) so light theme passes
+  WCAG AA. (#365)
+- **Per-call plan/task model selection** — `plan_model` and `task_model`
+  are now distinct from the conversation model and from each other, with
+  configurable reasoning effort per agent.  `ConfigStore` admin tab in
+  the console UI lets operators set defaults; per-call overrides
+  available via the `plan_agent` / `task_agent` tools. (#360, #361)
+- **Provider capability passthrough** — resolved per-model capabilities
+  (vision support, reasoning support, native web search, etc.) flow
+  through to provider clients so feature gating no longer relies on
+  string matching.  Server companion published in the same change. (#352)
+- **Claude Opus 4.7 support** — provider capabilities, tokenizer
+  awareness, and adaptive thinking semantics. (#357 — also in 1.3.1)
+- **Dashboard composer refactor** — unified single-flow create from the
+  per-node dashboard.  Multi-line textarea + collapsible Options panel
+  (model / judge / skill) + paperclip + drag-drop / paste-image + chip
+  strip.  Submit-button label dynamically toggles between `Create`
+  (empty) and `Send` (text or attachments staged); Enter and click both
+  go through the same `dashboardSubmit()`.  Replaces the inconsistent
+  prior split where Enter created+sent raw and the button opened a
+  separate modal.  Options panel state persists in `localStorage`;
+  active non-default selections render as an inline summary chip beside
+  the Options button; drag-over shows an explicit "Drop to attach"
+  overlay. (#362, #366)
+- **Workstream attachments — orphan reservation sweep** — periodic
+  background sweep clears `reserved_for_msg_id` on rows whose
+  `reserved_at` exceeds a 1-hour threshold, self-healing reservations
+  leaked by process crashes between reserve and consume.  Backed by a
+  partial index on `(reserved_at) WHERE reserved_at IS NOT NULL` so the
+  scan stays cheap as the consumed-history grows.  Threshold tracks
+  reservation age, not upload age, so a long-pending fresh send can't
+  be racially unreserved. (#363)
+- **`SendResponse` extended** — `attached_ids`,
+  `dropped_attachment_ids`, `priority`, `msg_id` fields exposed in
+  Pydantic + TypeScript SDKs so attachment-aware clients can detect
+  partial reservations and dequeue queued messages. (#365)
+
+### Changed
+
+- **`plan_model` and `task_model` now split** from the conversation
+  model and from each other — operators who rely on a single model for
+  all three should set both `plan_model` and `task_model` explicitly in
+  their config; otherwise both default to the conversation model so
+  behaviour is unchanged. (#54dd557)
+- **Channel notify-on-complete `channel_type` is no longer hardcoded
+  in the admin UI** — operators creating notify targets through the
+  skill admin form previously got `channel_type: "discord"` regardless
+  of what they wanted.  Existing skill JSON values are unaffected; only
+  newly created targets through the form differ. (#365)
+- **Slack adapter approval previews** — capped at 600 chars per item
+  with a 2700-char total budget so multi-tool approval batches never
+  exceed Slack's 3000-char `section.text` limit.  Truncated batches
+  show a `…and N more (preview truncated)` suffix. (#365)
+- **PostgreSQL deployment image** swapped from `bitnami/pgbouncer` to
+  `edoburu/pgbouncer` to track upstream releases and reduce image size.
+  No config changes required for typical deployments; review your helm
+  values if you depend on `bitnami`-specific environment variable
+  conventions. (#353)
+
+### Fixed
+
+- **`plan_resolved` SSE broadcast** — when one client resolved a plan
+  approval, other clients viewing the same workstream now have the
+  approval card dismissed in sync. (#87a9af1)
+- **Slack notification reply routing** — one notification reply
+  previously pinned every later assistant response for that workstream
+  to the notification thread until the bot restarted.  Reply-route
+  override now clears on `StreamEndEvent`. (#365)
+- **Slack plan-review mrkdwn fence** — plan content containing triple
+  backticks (very common — plans often quote code) no longer breaks the
+  surrounding fence and lets later content render as live markup.  The
+  shared `_sanitize_slack_preview` helper splices a zero-width space
+  inside any ``` ``` `` sequence while keeping single backticks
+  readable. (#365)
+- **Slack-routed workstreams now load the chat-specific system prompt**
+  via `client_type="chat"`, matching Discord. (#365)
+- **`/v1/api/workstreams/new` no longer emits a phantom
+  `ws_created`/`ws_closed` SSE pair** when attachment validation
+  rejects a multipart create.  Validation runs before the broadcast so
+  failed creates are silent on dashboards. (#362)
+- **Multipart Content-Type boundary preservation** in console routing
+  proxy — `boundary=` parameter is case-sensitive and was being
+  lowercased before forwarding to the upstream node, breaking parsing
+  for clients that used mixed-case boundaries (most browsers). (#362)
+- **Local-theme contrast for new badge colors** — `.scope-discord` and
+  `.scope-slack` first shipped with raw hex that failed WCAG AA on
+  light theme (1.8:1 / 2.4:1).  Theme-aware `--discord` / `--slack`
+  tokens with proper light variants now pass. (#365)
+
+### Security
+
+- **Slack approval per-user authentication** — only the session owner
+  can click Approve/Deny on a Slack tool-approval card.  Without this,
+  any channel member with view access could approve dangerous tool
+  calls initiated by someone else. (#355)
+- **Attachment ownership masking** — cross-user/cross-workstream
+  attachment ID lookups return 404 (not 403) so non-owners can't
+  enumerate workstream existence by response code. (#356)
+- Bumped Debian base image; remaining unfixable `jq` CVEs are
+  documented and exception-listed. (#aaea4d3)
+
+### Database migrations
+
+- **`037_workstream_attachments`** — new `workstream_attachments` table
+  with the lifecycle columns described above.  Indexes for ws_id,
+  pending lookups, message linkage, and reservation scoping.
+- **`038_workstream_attachments_reserved_at`** — adds `reserved_at`
+  column for the orphan-sweep staleness signal, plus a partial index
+  on `reserved_at IS NOT NULL` so the periodic scan is cheap.
+
+Both migrations are additive and idempotent, and the server applies
+them automatically on first startup against an existing 1.3.x database.
+No manual `alembic upgrade` step is required — though running it
+manually beforehand (e.g. as part of a phased deploy) remains safe.
+
+### SDK
+
+Python + TypeScript clients gained:
+
+- `AttachmentUpload` type
+- `upload_attachment(ws_id, filename, data, mime_type=None)`
+- `list_attachments(ws_id)`
+- `get_attachment_content(ws_id, attachment_id) → bytes / Blob`
+- `delete_attachment(ws_id, attachment_id)`
+- `send(message, ws_id, attachment_ids=...)` (extended)
+- `create_workstream(..., attachments=[...])` — multipart variant with
+  client-side `ws_id` generation for cluster-routed callers
+- Console SDK: `route_create_workstream(attachments=...)`,
+  `route_upload_attachment`, `route_list_attachments`,
+  `route_get_attachment_content`, `route_delete_attachment`
+- Refusal of `attachments + target_node` combination at the SDK
+  boundary (the multipart routing layer doesn't honor `target_node`,
+  so silently picking the wrong node is now an explicit error)
+
+## [1.3.1]
+
+### Added
+
+- Backport: Claude Opus 4.7 support (provider capabilities, tokenizer,
+  adaptive thinking). (#357)

+# Release Process
+
+Turnstone uses two parallel release tracks published from a single PyPI package.
+
+## Release Tracks
+
+| Track | Versions | Branch | Docker tags | PyPI install |
+|-------|----------|--------|-------------|--------------|
+| **Stable** | `1.1.0`, `1.1.1` | `stable/1.1` | `:1.1.0`, `:1.1`, `:stable`, `:latest` | `pip install turnstone` |
+| **Experimental** | `1.2.0a1`, `1.2.0a2` | `main` | `:1.2.0a1`, `:experimental` | `pip install turnstone --pre` |
+
+- **Stable** receives bugfixes only. Production-grade.
+- **Experimental** receives new features. May be rough around the edges.
+- When experimental matures, it is promoted to stable. The previous stable branch stops receiving patches.
+
+## Version Scheme
+
+[PEP 440](https://peps.python.org/pep-0440/) pre-release suffixes on a single package:
+
+- `1.0.0` — stable release
+- `1.1.0a1` — alpha (experimental)
+- `1.1.0b1` — beta (experimental, more stable)
+- `1.1.0rc1` — release candidate (experimental, nearly stable)
+- `1.1.0` — promoted to stable
+
+## Releasing an Experimental Version (from main)
+
+```bash
+scripts/release.sh 1.1.0a2 --push
+```
+
+This bumps `pyproject.toml` + `turnstone/__init__.py`, regenerates `uv.lock`, commits, tags `v1.1.0a2`, and pushes. CI runs, then publish + Docker workflows fire automatically.
+
+## Releasing a Stable Patch (from stable/X.Y)
+
+```bash
+git checkout stable/1.0
+git cherry-pick <commit-hash>    # bugfix from main
+scripts/release.sh 1.0.2 --push
+```
+
+## Promoting Experimental to Stable
+
+When `main` is ready for a stable release:
+
+```bash
+# 1. Tag the stable release on main
+scripts/release.sh 1.1.0 --push
+
+# 2. Create the stable maintenance branch from that tag
+git branch stable/1.1 v1.1.0
+git push origin stable/1.1
+
+# 3. Start the next experimental cycle on main
+scripts/release.sh 1.2.0a1 --push
+```
+
+The previous `stable/1.0` branch stops receiving patches at this point.
+
+## CI/CD Pipeline
+
+All releases are gated on CI success:
+
+1. `git push` with `v*` tag triggers **CI** (lint, typecheck, test, test-postgres, lock-check, security audit)
+2. On CI success, **Publish to PyPI** fires via `workflow_run`
+3. On CI success, **Publish Docker Image** fires via `workflow_run`
+
+Pre-release tags (`a`, `b`, `rc` suffixes) produce:
+- PyPI: pre-release version (not installed by default)
+- GitHub Release: marked as pre-release
+- Docker: `:experimental` alias + exact version tag
+
+Stable tags produce:
+- PyPI: stable version (default `pip install`)
+- GitHub Release: full release
+- Docker: `:stable`, `:latest`, `:X.Y`, `:X.Y.Z` tags
+
+## Dependency Updates
+
+Renovate targets `main` (experimental) only. Stable branches receive manual dependency updates via cherry-pick when security-relevant.

+## Per-Model Sampling Overrides
+
+The global `model.temperature`, `model.max_tokens`, and `model.reasoning_effort`
+settings serve as cluster-wide defaults. Individual models can override these
+via per-model settings in the `model_definitions` table (admin Models tab).
+
+Resolution order for sampling parameters:

+| Priority | Source |
+|----------|--------|
+| 1 (highest) | Per-model override (set in Models tab) |
+| 2 | Global default (set in Settings tab) |
+| 3 | Registry default (code) |
+
+When a per-model override is `NULL` (empty in the UI), the global default is
+used. Switching models via `/model <alias>` re-resolves sampling parameters
+from the new model's overrides or global defaults.
+
+**Removed settings:** `model.name` and `model.context_window` have been removed
+from ConfigStore. Model names and context windows are now configured per-model
+in the Models tab. A startup warning is logged if these keys appear in

+An MCP server that exposes tools for executing commands across a Turnstone cluster. Serves as a reference implementation for both MCP server patterns and Turnstone SDK usage.
 
 ## How it works
 
-This server uses Turnstone's SDK client (`TurnstoneServer`) to dispatch shell commands to specific nodes via HTTP. Remote agents execute the command and the raw bash output is captured directly from the `ToolResultEvent` stream — bypassing the costly "agent reads output → re-generates output as completion tokens" round-trip.
+This server uses the Turnstone console SDK (`TurnstoneConsole`) for node discovery and routing, and `TurnstoneServer` for per-node SSE streaming. The dispatch flow for each command is:
+
+1. **Route** — `TurnstoneConsole.route_create_workstream(target_node=..., auto_approve=True)` creates a workstream pinned to the target node via the console's hash-ring routing proxy, returning `ws_id` and `node_url`.
+2. **Execute** — `TurnstoneServer(node_url, token=...)` connects directly to the node's SSE stream using the same `TURNSTONE_API_TOKEN`. `send_and_wait(prompt, ws_id)` runs the command and the raw bash output is captured from the `ToolResultEvent` — bypassing the costly "agent reads output then re-generates output as completion tokens" round-trip.
+3. **Cleanup** — `TurnstoneConsole.route_close(ws_id)` closes the workstream.
