+
+Summary:
+- Oriented to the repository layout and prior collaboration artifacts (00 bootstrap questions and 01 proposal).
+- Created 01-round confirmation questions to secure explicit approval before planning.
+
+Details:
+- Added `collab/questions/01-codexhelper.md` and `collab/questions/01-codexhelper.llm.md` focused on confirming the proposal and minor options.
+- Will not create a plan until explicitly approved per AGENTS.md sequencing rules.
+
+Next Steps:
+- Await approval in `collab/questions/01-codexhelper.md`.
+- If approved, draft `collab/plan/01-codexhelper.md` and begin Phase 1 implementation.
+

+Date: 2025-09-17 15:28 (UTC)
+
+Summary:
+- Adopted one-way progression (no returning to prior step after approval) and in-place editing per step file.
+- Consolidated confirmation items into the proposal; removed redundant questions round.
+
+Details:
+- Updated AGENTS.md sequencing rules to codify one-way progression and `.llm.md` read policy.
+- Added approval checklist to `collab/proposals/01-codexhelper.md` and `.llm.md`.
+- Removed `collab/questions/01-codexhelper.*` to avoid back-stepping.
+
+Next Steps:
+- Await proposal approval in `collab/proposals/01-codexhelper.md`.
+- Then create `collab/plan/01-codexhelper.md`.

+Date: 2025-09-17 15:36 (UTC)
+
+Summary:
+- Captured the global system prompt directly (one-time exception) per request and aligned AGENTS.md to reference it.
+
+Details:
+- Added `prompts/global/system.md` and `prompts/global/system.llm.md`.
+- Updated AGENTS.md to note the canonical system rules location and reinforce `.llm.md`-only reading policy and one-way progression.
+
+Next Steps:
+- Use these artifacts for all subsequent work and generated projects.

+
+Date: 2025-09-17 15:42 (UTC)
+
+Summary:
+- Added seed AGENTS templates and a project AGENTS template for scaffolding.
+
+Details:
+- Created `meta/AGENTS.seed.md` and `meta/AGENTS.seed.llm.md` as bootstrap references.
+- Created `templates/project/_shared/AGENTS.md` to be copied into new projects.
+- Updated AGENTS.md to reference the seed templates.
+
+Next Steps:
+- When implementing `new-project`, copy `templates/project/_shared/AGENTS.md` into the project root.

+Date: 2025-09-17 15:48 (UTC)
+
+Summary:
+- Folded `meta/` seed AGENTS and `prompts/global/` into the proposal so the upcoming plan includes them.
+
+Details:
+- Updated `collab/proposals/01-codexhelper.md` and `.llm.md` to explicitly list `meta/AGENTS.seed.*`, `templates/project/_shared/AGENTS.md`, and `prompts/global/` in repo/project layouts and acceptance criteria.
+
+Next Steps:
+- Await proposal approval; then codify in `collab/plan/01-codexhelper.md`.
+

+
+Date: 2025-09-17 15:55 (UTC)
+
+Summary:
+- Added an explicit governance/propagation rule so that reusable workflow changes are folded into the global system prompt and AGENTS templates and reflected in proposal/plan.
+
+Details:
+- Updated `prompts/global/system.{md,llm.md}` with a Governance and Propagation section.
+- Updated `meta/AGENTS.seed.*` and `templates/project/_shared/AGENTS.md` to include propagation guidance.
+- Reflected this rule in `collab/proposals/01-codexhelper.{md,llm.md}`.
+
+Next Steps:
+- Apply this propagation practice for future non-project-specific instructions.
