+# #703 Git Wrapper Interactive and Auth Resilience
+
+## Objective
+
+Restore the deployed Git wrapper contract: issue-create supports interactive invocation and Gitea mutation behavior tolerates a stale Tea authenticated user by validating current identity and using the existing host-scoped API fallback.
+
+## Scope
+
+- `packages/mosaic/framework/tools/git/issue-create.sh`
+- `packages/mosaic/framework/tools/git/detect-platform.sh`
+- Git wrapper regression harnesses
+- This scratchpad
+
+## Requirements / acceptance evidence
+
+1. `issue-create -i` and `--interactive` prompt for missing issue fields without exposing credentials.
+2. Explicit command-line fields retain precedence and do not trigger prompt input.
+3. Gitea wrapper resolves the current user dynamically from the target host and does not rely on the saved Tea user identity.
+4. A Tea `GetUserByName` failure falls back to authenticated API creation.
+5. Existing body-safety, login-resolution, issue-create, and pr-create paths remain green.
+6. Source framework is re-seeded to deployed `~/.config/mosaic`, then deployed wrappers are verified end to end.
+
+## Plan
+
+1. Add failing shell regression harness for interactive input and stale Tea user fallback.
+2. Implement minimal helper and parser changes.
+3. Run wrapper harnesses, syntax checks, and repository baseline checks.
+4. Re-seed deployed framework and run live wrapper verification.
+5. Commit, queue guard, push, open PR, and stop for independent review.
+
+## Progress
+
+- Issue #703 filed before code; issue comment records #536 root cause and stale-login trigger.
+- Deployed wrapper `issue-create.sh -i` reproduced: `Unknown option: -i` (exit 1).
+- Live Tea mutation did not reproduce `GetUserByName` on this host because the current mosaicstack Tea login is valid. The test harness models the reported stale authenticated-user condition.
+- Implemented `-i` / `--interactive` prompt collection and a dynamic Tea `/user` validation. A stale Tea identity now selects the existing host-scoped Gitea API fallback before mutation for both issue and PR creation.
+- Re-seeded the framework with `MOSAIC_INSTALL_MODE=keep MOSAIC_SYNC_ONLY=1 bash packages/mosaic/framework/install.sh`. Installed and source wrapper SHA-256 values matched.
+- Live deployed verification: interactive issue-create opened then closed #704; installed dynamic identity resolved `jason.woltje`.
+
+## Verification
+
+- PASS: `packages/mosaic/framework/tools/git/test-issue-create-interactive-auth.sh`
+- PASS: `packages/mosaic/framework/tools/git/test-issue-create-body-safety.sh`

+# TESS-M1-SEC-001 — Command authorization and exact-action approval
+
+- Issue/milestone: #707 / M1
+- Branch: `fix/tess-command-authz`
+- Requirement: `TESS-SEC-002`, with approval binding controls from `TESS-SEC-007`
+- Scope: `apps/gateway` only, plus required in-repo security/developer documentation.
+
+## Plan
+
+1. Locate the gateway command executor, command metadata, authorization context, and existing test conventions.
+2. Write abuse/authz tests before production changes. Expected red cases: non-admin blocked from admin/system command; forged caller scope cannot authorize; privileged/destructive action requires durable exact-action approval; expired/replayed/mutated approvals deny.
+3. Implement server-derived role/scope enforcement and durable approval validation/consumption with audit results.
+4. Run focused security tests, then repository baseline gates: typecheck, lint, format-check, test.
+5. Run independent security/code review, commit, queue-guard, push, and open the PR to `main` through the stated Gitea API fallback. Stop after PR creation.
+
+## Assumptions
+
+- The existing gateway persistence interface is the available durable approval boundary. If no persistence abstraction exists, a minimal injectable repository interface will be introduced rather than an in-memory approval implementation, because TESS-SEC-002/007 require durable enforcement.
+- “Exact action” is a canonical digest over structured command identity and normalized arguments; role/scope checks always use authenticated server context, not client-declared claims.
+
+## TDD evidence
+
+- Pending: abuse/authz test written and observed red before implementation.
+
+## Verification evidence
+
+- Pending.
