### How It Works
Each workstream maintains its own `.planning/` directory subtree. When you switch workstreams, GSD swaps the active planning context so that `/gsd:progress`, `/gsd:discuss-phase`, `/gsd:plan-phase`, and other commands operate on that workstream's state.
Each workstream maintains its own `.planning/` directory subtree. When you switch workstreams, GSD swaps the active planning context so that `/gsd:progress`, `/gsd:discuss-phase`, `/gsd:plan-phase`, and other commands operate on that workstream's state. Active context is session-scoped when the runtime exposes a stable session identifier, which prevents one terminal or AI instance from repointing another instance's `STATE.md`.
This is lighter weight than `/gsd:new-workspace` (which creates separate repo worktrees). Workstreams share the same codebase and git history but isolate planning artifacts.

@@ -9,8 +9,55 @@ parallel milestone work by multiple Claude Code instances on the same codebase.
1. `--ws <name>` flag (explicit, highest priority)
2. `GSD_WORKSTREAM` environment variable (per-instance)
3. `.planning/active-workstream` file (shared, last-writer-wins)
4. `null` — flat mode (no workstreams)
3. Session-scoped active workstream pointer in temp storage (per runtime session / terminal)
4. `.planning/active-workstream` file (legacy shared fallback when no session key exists)
5. `null` — flat mode (no workstreams)
## Why session-scoped pointers exist
The shared `.planning/active-workstream` file is fundamentally unsafe when multiple
Claude/Codex instances are active on the same repo at the same time. One session can
silently repoint another session's `STATE.md`, `ROADMAP.md`, and phase paths.
GSD now prefers a session-scoped pointer keyed by runtime/session identity
(`GSD_SESSION_KEY`, `CODEX_THREAD_ID`, `CLAUDE_CODE_SSE_PORT`, terminal session IDs,
or the controlling TTY). This keeps concurrent sessions isolated while preserving
legacy compatibility for runtimes that do not expose a stable session key.
## Session Identity Resolution
When GSD resolves the session-scoped pointer in step 3 above, it uses this order:
1. Explicit runtime/session env vars such as `GSD_SESSION_KEY`, `CODEX_THREAD_ID`,
`CLAUDE_SESSION_ID`, `CLAUDE_CODE_SSE_PORT`, `OPENCODE_SESSION_ID`,
`GEMINI_SESSION_ID`, `CURSOR_SESSION_ID`, `WINDSURF_SESSION_ID`,
`TERM_SESSION_ID`, `WT_SESSION`, `TMUX_PANE`, and `ZELLIJ_SESSION_NAME`
2. `TTY` or `SSH_TTY` if the shell/runtime already exposes the terminal path
3. A single best-effort `tty` probe, but only when stdin is interactive
If none of those produce a stable identity, GSD does not keep probing. It falls
back directly to the legacy shared `.planning/active-workstream` file.
This matters in headless or stripped environments: when stdin is already
non-interactive, GSD intentionally skips shelling out to `tty` because that path
cannot discover a stable session identity and only adds avoidable failures on the
routing hot path.
## Pointer Lifecycle
Session-scoped pointers are intentionally lightweight and best-effort:
- Clearing a workstream for one session removes only that session's pointer file
- If that was the last pointer for the repo, GSD also removes the now-empty
per-project temp directory
- If sibling session pointers still exist, the temp directory is left in place
- When a pointer refers to a workstream directory that no longer exists, GSD
treats it as stale state: it removes that pointer file and resolves to `null`
until the session explicitly sets a new active workstream again
GSD does not currently run a background garbage collector for historical temp
directories. Cleanup is opportunistic at the pointer being cleared or self-healed,
and broader temp hygiene is left to OS temp cleanup or future maintenance work.
