NVDA and other screen readers ignore the title attribute on interactive
elements and non-interactive divs. Add aria-label alongside title on:
- Stop All button (dynamic label reflects active task count)
- Restart All button (dynamic label reflects pending workspace count)
- StatusPill component (online/offline/failed/provisioning counts)
- WsStatusPill component (connected/connecting/disconnected variants)
Inner dot and text spans get aria-hidden="true" so the screen reader
reads the single aria-label rather than individual child nodes.

WCAG 1.3.1 / 4.1.3: the error div that appears after a failed workspace
deploy or blank-workspace create had no ARIA live region, so screen
readers never announced it. Adding role="alert" makes the message an
implicit aria-live="assertive" region so assistive technology surfaces
the error immediately without requiring the user to navigate to it.

Wire WCAG 1.3.1 label associations: 6 bare <label>+control pairs in
ConfigTab (Description, Tier, Runtime, Effort, Task Budget, Backend) now
use stable useId() IDs with matching htmlFor/id. Field helper in
DetailsTab updated to generate its own fieldId via useId() and inject it
into the child element via cloneElement, so every Name/Role/Tier field in
edit mode is correctly associated without requiring call-site changes.

When a cron fires, the scheduler now fetches the last 10 messages from
the workspace's Slack channel via conversations.history and prepends them
to the cron prompt as '[Slack channel context — recent team messages]'.
This gives each agent ambient awareness of what peers are doing:
- Backend sees Frontend posted 'PR #840 ready for review' → can check
- Security Auditor sees Backend posted 'new endpoint added' → plans review
- PM sees all engineering activity → better synthesis in rollup
Implementation:
- slack.go: FetchChannelHistory() calls conversations.history, filters
bot's own messages, returns last N as SlackHistoryMessage structs
- manager.go: FetchWorkspaceChannelContext() looks up the workspace's
Slack config, fetches history, formats as readable context block
- scheduler.go: ChannelBroadcaster interface extended with
FetchWorkspaceChannelContext; fireSchedule injects context before
the cron prompt (prepended, not appended, so the agent sees team
context BEFORE its task instructions)
Best-effort: if Slack API fails or workspace has no channels, the
prompt is unchanged. Truncated to 200 chars per message, 10 messages
max to keep prompt overhead bounded.

Code review findings addressed:
Critical:
1. Bot echo loop: add bot_id + subtype='bot_message' check in ParseWebhook
to prevent outbound auto-posts from triggering inbound → infinite loop
2. Connection leak: close resp.Body immediately after reading instead of
defer inside loop (was holding N connections open for N chunks)
3. Cancelled context: auto-post goroutine now uses context.Background()
with 30s timeout instead of inheriting fireCtx (which gets cancelled
by deferred cancel() when fireSchedule returns)
4. Slug validation: regex ^[a-zA-Z0-9 _-]+$ rejects path traversal and
special chars in [slug] routing
Improvements:
5. Shared HTTP client (slackHTTPClient) for connection pooling instead of
per-request &http.Client{}
6. Rune-safe truncation in BroadcastToWorkspaceChannels for CJK/emoji
7. Log async HandleInbound errors instead of silently discarding
8. url_verification challenge properly returned (c.JSON with challenge)

Humans type [backend] what's #800? in a shared #mol-engineering channel
and the message routes specifically to Backend Engineer's workspace.
Matching logic (case-insensitive):
[pm] → PM
[backend] → Backend Engineer
[dev-lead] → Dev Lead
[security] → Security Auditor (prefix match on 'security-auditor')
Unknown slugs return the available agent list for that channel so the
user knows what slugs are valid.
Messages without a [slug] prefix route to the first matching workspace
(backward compat with Level 2).

Level 1 — Auto-post cron output to Slack:
- scheduler.go: captures A2A response body, extracts agent text via
extractResponseSummary(), broadcasts to workspace's configured Slack
channels on successful non-empty cron completions
- manager.go: adds BroadcastToWorkspaceChannels() — fans out to all
enabled channels for a workspace (engineering+firehose for eng agents,
research+firehose for research agents, etc.)
- main.go: wires scheduler → channel manager via SetChannels()
- Truncates output to 500 chars for Slack readability
Level 2 — Inbound Slack messages route to workspaces:
Already implemented by the existing webhook handler (POST /webhooks/slack)
+ the ParseWebhook method in slack.go which handles both Events API JSON
payloads and slash command form-encoded payloads. Needs Slack App Events
API URL configured to: https://<platform-host>/webhooks/slack
Also in this commit:
- slack.go: dual-mode adapter (bot_token + webhook fallback)
- 031 migration: pgvector guard wraps entire DO block

Slack adapter: adds chat.postMessage mode alongside legacy webhooks.
When bot_token is configured, uses chat:write.customize for per-agent
display name + emoji on every message. Each of the 15 active agents
posts with a distinct identity (PM 💼, Backend ⚙️, etc.).
5 channels configured:
#mol-engineering — PM, Dev Lead, Frontend, Backend, QA, Security, UIUX, Docs
#mol-research — Research Lead, Market Analyst, Tech Researcher, Competitive Intel
#mol-ops — DevOps, Triage, Offensive Security
#mol-ceo-feed — PM synthesized rollup (CEO-facing)
#mol-firehose — all agents (raw feed)
Tested live: 5 test messages across 4 channels, all ok=true.
pgvector migration: moved ALTER TABLE + CREATE INDEX inside the DO
block so the entire migration is skipped when pgvector extension is
unavailable (was crashing platform on restart — the guard caught
CREATE EXTENSION but execution continued to ALTER TABLE which used
the non-existent vector type).

Replaces the racy SELECT-then-Stop two-step in HibernateWorkspace with a
three-step atomic pattern that eliminates the TOCTOU window (SAFE-819):
1. Atomic claim: single UPDATE WHERE id=$1
AND status IN ('online','degraded')
AND active_tasks = 0
— rowsAffected=0 means another caller already claimed it or tasks
arrived; we abort immediately without calling Stop.
2. provisioner.Stop: safe because status='hibernating' blocks new task
routing between step 1 and step 2 (no new task can be dispatched).
3. Final UPDATE to 'hibernated': records the completed hibernation.
Also adds stopFnOverride func(ctx, id) to WorkspaceHandler (always nil in
production) so tests can count Stop calls without a running Docker daemon.
Tests added/updated (13 total across 2 files):
- TestHibernateWorkspace_ActiveTasksNotHibernated
- TestHibernateWorkspace_AlreadyHibernatingNotHibernated
- TestHibernateWorkspace_SuccessPath
- TestHibernateWorkspace_ConcurrentOnlyOneStop
- TestHibernateWorkspace_DBErrorOnClaim
- Updated 3 existing HibernateWorkspace tests + 1 HTTP handler test

Add role="separator" + aria-valuenow/min/max/orientation + tabIndex={0}
to make the resize handle focusable and discoverable by screen readers
(WAI-ARIA slider pattern). Add onKeyDown handler: ArrowLeft/Right moves
by 16px, Home/End snaps to min/max. Persist width to localStorage on
keyboard resize, matching the existing mouse behaviour.
Focus ring uses focus-visible:ring-2 to avoid showing on mouse click.

Previously loadMessagesFromDB swallowed all errors and returned [] — a
network failure was indistinguishable from an empty history, so the user
had no way to know loading failed. Now the function returns
{ messages, error } and the MyChatPanel renders a role="alert" banner
with the error message and a Retry button when messages are empty and
a load error occurred.

Replace title attribute (not read by screen readers for truncated text)
with aria-label, add role="status" so live regions announce the error,
and raise text color from text-amber-300/60 (~2.1:1) to text-amber-400
(~10.6:1) to meet WCAG AA contrast (4.5:1 minimum).

The ALTER TABLE and CREATE INDEX referenced vector(1536) outside the
exception-handling DO block, so when pgvector wasn't installed they
crashed the migration runner — blocking ALL E2E runs on main.
Fix: move all DDL inside the single DO block so the EXCEPTION handler
catches any pgvector-related failure and skips the entire migration.
