-## MAIN BRANCH EXECUTION GUARD
+## WORKSTREAM BRANCH EXECUTION GUARD
 
 Before any BUILD execution, Codex must verify the current git branch.
 
 Rules:
-- The required execution branch is:
+- Approved execution branches are:
   - `main`
-- If the current branch is not `main`:
+  - approved team workstream branches
+- Approved team workstream branch format:
+  - `team/<TEAM>/<workstream>`
+- Workstream branch examples:
+  - `team/ALPHA/game-hub`
+  - `team/BETA/messages`
+  - `team/GAMMA/admin`
+- The repository must be clean before file changes.
+- The current branch must not be detached HEAD.
+- The current branch must have an origin upstream unless a new PR branch has just been created from an approved execution branch.
+- Local branch HEAD must match origin branch HEAD when an origin upstream exists.
+- TEAM ownership must match the approved workstream branch and requested PR scope.
+- PR scope must stay inside TEAM ownership.
+- If the current branch is neither `main` nor an approved team workstream branch:
   - HARD STOP.
   - Do not create code changes.
   - Do not create implementation PRs.
   - Do not create ZIP artifacts.
   - Do not continue execution.
+- If the repository is dirty, HARD STOP.
+- If the current branch is detached HEAD, HARD STOP.
+- If local branch HEAD does not equal origin branch HEAD when an origin upstream exists, HARD STOP.
+- If the current branch is ahead of origin or has unpushed commits, HARD STOP.
+- If TEAM ownership mismatches the branch or scope, HARD STOP.
+- If cross-team scope is attempted without explicit Master Control assignment, HARD STOP.
 - Codex must report:
   - current branch
-  - expected branch (`main`)
+  - expected branch (`main` or approved `team/<TEAM>/<workstream>`)
   - local branches found
-- Codex may continue only after the user explicitly returns to `main`.
+  - upstream branch
+  - local/origin sync PASS/FAIL
+  - TEAM ownership PASS/FAIL
+- Codex may continue only after the user explicitly moves to `main` or an approved team workstream branch and all guard checks pass.
 
 Exception:
-- Explicit branch-audit or branch-comparison PRs may inspect non-main branches but must not perform implementation work on them.
+- Explicit branch-audit or branch-comparison PRs may inspect unapproved branches but must not perform implementation work on them.
 
 Required report output:
 - Current branch
+- Expected branch
+- Upstream branch
+- Local/origin sync PASS/FAIL
+- TEAM ownership PASS/FAIL
 - Branch validation PASS/FAIL

 ## OWNER-CONTROLLED STABLE AND MERGE APPROVAL
 
 Stable promotion and merge approval are owner-controlled.

 - Codex may prepare scoped changes, reports, validation evidence, ZIP artifacts, branches, and PRs.
-- Codex must not merge a PR or mark a workstream stable without explicit approval from the assigned Team Alpha or Team Beta owner.
+- Codex must not merge a PR or mark a workstream stable without explicit approval from the assigned Team Alpha, Team Beta, or Team Gamma owner.

+
+Confirmed:
+- `MAIN BRANCH EXECUTION GUARD` is no longer present.
+- `WORKSTREAM BRANCH EXECUTION GUARD` is present.
+- The main-only BUILD start hard stop is gone.
+- Execution is allowed from `main` or approved team workstream branches.
+- Approved branch format is `team/<TEAM>/<workstream>`.
+- Hard stops remain for dirty repo, unapproved branch, TEAM mismatch, cross-team scope, detached HEAD, local/origin mismatch, and unpushed commits.
+- GitHub authoritative sync governance remains present.
+- Local-only commits remain prohibited.
+- Runtime code was not changed.
+- EOD merge approval remains owner-controlled and requires explicit approval.

+## Validation Notes
+
+Static validation was sufficient because this PR updates governance documentation only.
+
+Skipped lanes:
+- Playwright was not run because no UI route, component, or browser behavior changed.
+- Samples smoke was not run because samples are outside the requested docs/static validation scope.
