 ## Active Objective
 Build the FESA structural solver foundation around the initial feature `mitc4-linear-static-shell`.
 
+## Repository Context
+- Canonical remote repository: `https://teagit.mimi1011.synology.me/baram2584/FESADev.git`
+- Default remote name: `origin`
+- Shared baseline branch: `dev`
+- New task branches should use `codex/<short-task-name>` unless the user requests otherwise.

 ## Current High-Level Plan
 1. Maintain project-level documentation and handoff files.
 2. Analyze new solver feature requirements for `mitc4-linear-static-shell`.

 - `python scripts/validate_workspace.py` remains the default validation path.
 - MITC4 reference comparison covers nodal displacement, reaction, element internal force/resultant, and stress.
 - Result comparison uses a single tolerance value `1e-5` with absolute-or-relative pass logic.
+- Agents can identify the canonical git remote and shared baseline branch from the project handoff documents.
 
 ## Coordination Rules
 - Update this file when the plan, scope, ordering, or acceptance criteria change.
 - Update `docs/PROGRESS.md` after completing work or running validation.
 - Update `docs/WORKNOTE.md` after mistakes, failed approaches, environment traps, or decisions that future Agents should not rediscover.
 - Keep `.codex/agents/*.toml` and `.codex/skills/*/SKILL.md` pointed at `docs/AGENT_RULES.md` for common operating rules.
+- Verify `git status --short --branch` and `git remote -v` at the start of git-aware work.
 
 ## Known Blockers
 - No CMake project exists yet, so `python scripts/validate_workspace.py` currently takes the no-op path.
