Adds wide-event observability for the supervisor: one flat-keyed JSON line per dequeue iteration, workload-server route, and run socket lifecycle event. Events carry `trace_id` sourced from the inbound W3C traceparent plus `meta.run_id` and related identifiers, so they join across services by run. The outbound warm-start POST also forwards the inbound traceparent so the upstream receiver continues the same trace instead of minting a new one. Off by default behind `TRIGGER_WIDE_EVENTS_ENABLED`. With the flag off, no events are emitted, no ALS state is allocated, and the outbound warm-start request is unchanged — every call site was audited to confirm the off path is byte-identical to current behavior. Dequeue-path phase timings recorded under `phase.<name>.duration_ms`: `restore`, `warm_start`, `workload_create`. A `path_taken` extra distinguishes `restore` / `warm_start` / `cold_create` / `skipped_no_image`. Refs TRI-9480.

Server Changes
This directory tracks changes to server-only components (webapp, supervisor, coordinator, etc.) that are not captured by changesets. Changesets only track published npm packages — server changes would otherwise go undocumented.
When to add a file
Server-only PRs: If your PR only changes apps/webapp/, apps/supervisor/, apps/coordinator/, or other server components (and does NOT change anything in packages/), add a .server-changes/ file.
Mixed PRs (both packages and server): Just add a changeset as usual. No .server-changes/ file needed — the changeset covers it.
Package-only PRs: Just add a changeset as usual.
File format
Create a markdown file with a descriptive name:

With this format:
---

Description
The body text (below the frontmatter) is a one-line description of the change. Keep it concise — it will appear in release notes.
Writing guidance
These entries are public-facing - they ship verbatim in user-visible release notes. A few rules to keep them clean:
- One sentence is usually enough. The body is the bullet in the changelog. If you need a paragraph, you're probably describing the implementation rather than the change.
- Describe behavior, not implementation. Skip internal scopes, middleware names, library specifics, framework internals. Users care about what's different for them, not how it's wired.
- Never name internal tools or infra. Observability stacks, internal services, infra components, monitoring backends, CI surfaces, AWS specifics - none of these belong in user-facing notes.
Lifecycle
- Engineer adds a
.server-changes/file in their PR - Files accumulate on
mainas PRs merge - The changeset release PR includes these in its summary
- After the release merges, CI cleans up the consumed files
