+# SeedPass Dev Control Center
+
+Last updated: 2026-03-02  
+Branch baseline: `beta`
+
+This is the single source-of-truth document to decide what to work on next.
+
+## 1) Current Health Gate
+
+Run before starting any new slice:
+
+```bash
+git pull --rebase origin beta
+PATH=".venv/bin:$PATH" scripts/run_ci_tests.sh
+```
+
+Latest verification in this session:
+- `origin/beta` matched local `beta` (no new remote commits to pull).
+- `scripts/run_ci_tests.sh`: PASS
+  - determinism gate: PASS
+  - full suite: `979 passed, 16 skipped`
+  - coverage: `85.65%`
+
+## 2) Canonical Status Sources
+
+Use these docs as inputs, but treat this file as the decision layer:
+
+- TUI v2 plan: `docs/tui_v2_plan.md`
+- TUI parity backlog: `docs/tui_v2_parity_backlog.md`
+- TUI parity checklist: `docs/tui_v2_parity_checklist.md`
+- Cutover memo: `docs/tui_v2_cutover_decision.md`
+- Security readiness: `docs/security_readiness_checklist.md`
+- Supply-chain integrity: `docs/supply_chain_release_integrity.md`
+- QA roadmap: `docs/agent_testing_roadmap.md`
+- Agent TUI testing: `docs/ai_agent_tui_testing.md`
+- KB scale validation: `docs/kb_scale_validation.md`
+- Beta hardening report: `docs/beta_hardening_2026-03-02.md`
+
+## 3) What Is Still Open
+
+### Parity / Product
+- `docs/tui_v2_parity_checklist.md` still marks:
+  - Full legacy workflow coverage: **Pending**
+
+### Security Readiness
+- `docs/security_readiness_checklist.md` still marks:
+  - #4 Backup/restore integrity: **In Progress**
+  - #5 Nostr sync security/resilience: **In Progress**
+  - #7 Testing gates/quality thresholds: **In Progress**
+  - #8 Supply chain/release integrity: **In Progress**
+  - #9 Operational runbooks: **Not Started**
+  - #10 External audit/rollout: **Not Started**
+
+### Supply Chain Specific
+- `docs/supply_chain_release_integrity.md` remaining work:
+  - execute at least one tagged production release through integrity workflow and record evidence
+  - resolve/document exception `GHSA-wj6h-64fc-37mp`
+  - enforce release protection rules
+  - add/validate maintainer verification runbook
+
+## 4) Recommended Next Steps (Priority Order)
+
+1. Close remaining TUI v2 legacy parity gap with an explicit action matrix and tests.
+2. Strengthen testing gates by adding critical coverage thresholds for TUI v2 and key service modules used by v2.
+3. Advance Nostr resilience validation with deterministic failure-mode suites (then optional real-relay soak lane).
+4. Update cutover memo to reflect current reality and remaining concrete blockers.
+5. Finish supply-chain readiness evidence and release-protection policy.
+
+## 5) Next Slice Definition (Recommended Immediate Work)
+
+### Slice A: “Legacy Parity Closure Matrix”
+
+Deliverables:
+- Add `docs/tui_v2_legacy_parity_matrix.md` mapping legacy interactive actions to TUI v2 equivalents (or explicit gaps).
+- Add tests for any currently uncovered high-value legacy actions surfaced by that matrix.
+- Update `docs/tui_v2_parity_checklist.md` to remove or narrow “Full legacy workflow coverage: Pending”.
+
+Exit criteria:
+- Matrix exists, reviewed, and linked from this document.
+- New tests pass in CI-equivalent run.
+- Remaining parity gaps are explicit and severity-ranked.
+
+## 6) Working Rule
+
+When priorities conflict:
+1. Keep CI green.
+2. Close user-visible parity gaps.
+3. Raise security/testing gates.
+4. Then optimize docs and process.

   - Search input can capture keystrokes by default; test now focuses `#entry-list` before keybinding presses to exercise app-level binding path reliably.
 - Validation run:
   - `pytest -q src/tests/test_tui_v2_textual_interactions.py src/tests/test_tui_v2_action_matrix.py src/tests/test_tui_v2_helpers.py` -> `34 passed`.

+## 2026-03-02 Centralized dev planning doc added
+- Added `docs/dev_control_center.md` as the single decision-layer document for what to work on next.
+- The control center now links plan, parity, security, QA, and hardening documents and includes a prioritized next-step queue.
+- Added `docs/README.md` “Start Here” link pointing to `dev_control_center.md`.
+- Pre-slice health verification executed first:
+  - remote sync check on `origin/beta` (no new remote commits)
+  - `scripts/run_ci_tests.sh` pass with full suite: `979 passed, 16 skipped`, coverage `85.65%`.
