Closes this feature request:
[https://triggerdev.featurebase.app/p/isolated-dev-sessions-for-multiple-local-trigger-dev-instances](https://triggerdev.featurebase.app/p/isolated-dev-sessions-for-multiple-local-trigger-dev-instances)
### Feature notes:
- CLI `trigger dev` works as before
- `trigger dev --branch my-branch` to create a new branch and run
against it.
- `trigger dev archive --branch my-branch` to archive (or in webapp).
- New webapp page to manage and archive dev branches, currently feature
flagged.
### Implementation details:
- No changes to data model, no backfill. `isBranchableEnvironment`
column is ignored for dev branches, we use `parentEnvironmentId IS NULL`
instead.
- `x-trigger-branch` overloaded for preview and dev branches
- New `TRIGGER_DEV_BRANCH` env var available locally.
`TRIGGER_PREVIEW_BRANCH` overloaded for child runs.
- Lots of new glue code to sanitise the branch checks.
### Rollout
- Deploy webapp/API changes (all backwards compatible)
- Manual tests on some orgs
- Deploy docs, release CLI, flip feature flag for webapp feature
### NB
- `api.v1.projects.$projectRef.environments.ts` will return
`isBranchableEnvironment: true` for all dev environments.
### Prerequisites
- [x] Typecheck will not pass until we make a new release of
`@trigger.dev/platform` and bump it here
## Summary
Documents the Sessions HTTP API for non-SDK and server-to-server
callers, which until now appeared only in the conceptual
[ai-chat/sessions](https://trigger.dev/docs/ai-chat/sessions) page.
## What's covered
- **Sessions API reference** —
`create`/`list`/`retrieve`/`update`/`close` added to the OpenAPI spec
and a new "Sessions API" group (`management/sessions/*`), mirroring the
Runs API.
- **Channel endpoints** — a reference page for the `.in`/`.out` realtime
HTTP endpoints (append, SSE read, records drain), the wire protocol,
`Last-Event-ID` resume, and the per-direction auth boundary (`.out`
append is secret-key only).
- **Session scopes** — `read:sessions:{id}` / `write:sessions:{id}` in
the authentication docs, with the capability boundary and the 1h token
TTL.
Cross-linked with the SDK-side `ai-chat/sessions` page. Verified by
rendering each page on the Mintlify dev server.
## Summary
Docs follow-up for #3683 (`TriggerClient` for per-instance SDK
configuration). Adds a dedicated reference page and threads the new
pattern through the existing management + preview-branches docs.
## What's in
**New page** `docs/management/multiple-clients.mdx` — when to use
`TriggerClient` vs `configure()` vs `auth.withAuth`, env-var fallback
rules, isolation contract, namespace surface, `inheritContext` opt-in,
and a when-to-use-what table.
**Updated pages**
- `docs/management/authentication.mdx` — rewrote the `auth.withAuth`
section to reflect the now-ALS-backed semantics (the prior version
warned about concurrency races and pointed at issue #3298 as a tracked
fix; that fix landed in #3683). Added `tr_preview_*` to the key prefix
list. Reframed the multi-target use case to lead with `TriggerClient`,
with `auth.withAuth` as the temporary-override helper.
- `docs/management/overview.mdx` — added a `Multiple clients in one
process` subsection.
- `docs/deployment/preview-branches.mdx` — added a `Triggering across
multiple branches from one process` example.
- `docs/triggering.mdx` — one-liner pointing at the new page for
cross-project triggering.
- `docs/docs.json` — slotted `management/multiple-clients` into the
Management API nav, right after authentication.
Paired with #3683.
## Test plan
- [ ] Mintlify preview renders cleanly
- [ ] Code samples in each updated page run as documented
- [ ] Cross-page links resolve (`/management/multiple-clients`,
`/management/authentication`)
