## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Agents run shell commands during workspace provisioning (git
worktree creation, runtime services)
> - When `process.env.SHELL` is unset, the code falls back to `/bin/sh`
> - But on Windows with Git Bash, `/bin/sh` doesn't exist as an absolute
path — Git Bash provides `sh` on PATH instead
> - This causes `child_process.spawn` to throw `ENOENT`, crashing
workspace provisioning on Windows
> - This PR extracts a `resolveShell()` helper that uses `$SHELL` when
set, falls back to `sh` (bare) on Windows or `/bin/sh` on Unix
> - The benefit is that agents running on Windows via Git Bash can
provision workspaces without shell resolution errors
## Summary
- `workspace-runtime.ts` falls back to `/bin/sh` when
`process.env.SHELL` is unset
- On Windows, `/bin/sh` doesn't exist → `spawn /bin/sh ENOENT`
- Fix: extract `resolveShell()` helper that uses `$SHELL` when set,
falls back to `sh` on Windows (Git Bash PATH lookup) or `/bin/sh` on
Unix
Three call sites updated to use the new helper.
Fixes#892
## Root cause
When Paperclip spawns shell commands in workspace operations (e.g., git
worktree creation), it uses `process.env.SHELL` if set, otherwise
defaults to `/bin/sh`. On Windows with Git Bash, `$SHELL` is typically
unset and `/bin/sh` is not a valid path — Git Bash provides `sh` on PATH
but not at the absolute `/bin/sh` location. This causes
`child_process.spawn` to throw `ENOENT`.
## Approach
Rather than hard-coding a Windows-specific absolute path (e.g.,
`C:\Program Files\Git\bin\sh.exe`), we use the bare `"sh"` command which
relies on PATH resolution. This works because:
1. Git Bash adds its `usr/bin` directory to PATH, making `sh` resolvable
2. On Unix/macOS, `/bin/sh` remains the correct default (it's the POSIX
standard location)
3. `process.env.SHELL` takes priority when set, so this only affects the
fallback
## Test plan
- [x] 7 unit tests for `resolveShell()`: SHELL set, trimmed, empty,
whitespace-only, linux/darwin/win32 fallbacks
- [x] Run a workspace provision command on Windows with `git_worktree`
strategy
- [x] Verify Unix/macOS is unaffected

The agent.task_completed event was sending adapterType (e.g. "claude_local")
as the agent_role dimension instead of the actual role (e.g. "engineer").

Expose telemetry.track through the plugin SDK and server host bridge, forward plugin-prefixed events into the shared telemetry client, and demonstrate the capability in the kitchen sink example.\n\nCo-Authored-By: Paperclip <noreply@paperclip.ing>
Restructure the TelemetryClient to send the correct backend envelope
format ({app, schemaVersion, installId, events: [{name, occurredAt, dimensions}]})
instead of the old per-event format. Update all event dimension names
to match the backend registry (agent_role, adapter_type, error_code, etc.).

The TelemetryClient only flushed at 50 events, so the server silently
lost all queued telemetry on restart. Add startPeriodicFlush/stop methods
to TelemetryClient, wire up 60s periodic flush in server initTelemetry,
and flush on SIGTERM/SIGINT before exit.

Add the shared telemetry sender, wire the CLI/server emit points,
and cover the config and completion behavior with tests.

* fix: auto-detect default branch for worktree creation when baseRef not configured
When creating git worktrees, if no explicit baseRef is configured in
the project workspace strategy and no repoRef is set, the system now
auto-detects the repository's default branch instead of blindly
falling back to "HEAD".
Detection strategy:
1. Check refs/remotes/origin/HEAD (set by git clone / remote set-head)
2. Fall back to probing refs/remotes/origin/main, then origin/master
3. Final fallback: HEAD (preserves existing behavior)
This prevents failures like "fatal: invalid reference: main" when a
project's workspace strategy has no baseRef and the repo uses a
non-standard default branch name.

* fix: address Greptile review - fix misleading comment and add symbolic-ref test
- Corrected comment to clarify that the existing test exercises the
heuristic fallback path (not symbolic-ref)
- Added new test case that explicitly sets refs/remotes/origin/HEAD
via `git remote set-head` to exercise the symbolic-ref code path

When the adapter type changes via PATCH, the server only preserved
instruction bundle keys (instructionsBundleMode, etc.) from the
existing config. Adapter-agnostic keys like env, cwd, timeoutSec,
graceSec, promptTemplate, and bootstrapPromptTemplate were silently
dropped if the PATCH payload didn't explicitly include them.
This caused env var data loss when adapter type was changed via the
UI or API without sending the full existing adapterConfig.
The fix preserves these adapter-agnostic keys from the existing config
before applying the instruction bundle preservation, matching the
UI's behavior in AgentConfigForm.handleSave.

Timer wakes had no taskKey, so they couldn't use agentTaskSessions for
session resume. Adds a synthetic __heartbeat__ task key for timer wakes
so they participate in the full session system.
Includes 6 dedicated unit tests for deriveTaskKeyWithHeartbeatFallback.
