IP-317 Planning Phase Handoff

Phase: plan
Status: review corrections applied; independent re-review pending
Scope: IP-317, including child stories IP-325 and IP-326
Artifacts: SPEC.md and execution-ready PLAN.md in this folder
Sources: approved spec; completed Q1-Q28 context/projection grill decisions; live Linear IP-317, IP-325, and IP-326 descriptions, relations, and comments; IP-319 characterization/readiness evidence; current compiler/scaffold/projection code and tests
Validation: every child acceptance signal maps to a task and final assertion; all Tn fields, RED/GREEN commands, dependency waves, exact write scopes, review/docs gates, and branch/base constraints are present; targeted Oxfmt and diff checks pass
Review/debug/docs state: plan self-review complete; implementation, runtime debugging, docs ingest, backlog mutation, commit, push, and PR creation did not run
UI Evidence: not applicable
Next suggested route: implement-spec after a readonly plan-reviewer pass, preserving T1-T3/IP-325 before T4-T8/IP-326; T10 remains readonly parent validation and routes findings back to owning tasks
Branch/base intent: parent draft PR #76 uses team/stefan/refactor-cli-architecture; child branch team/stefan/ip-317-context-plan targets that parent branch, never main; parent and child remain unmerged and undeployed
Blockers: no product or dependency blocker; final independent plan review remains required before implementation
