From 30a3288c3d242ca0f4cc759f6861218ff0c620a9 Mon Sep 17 00:00:00 2001 From: CleverThis Date: Fri, 10 Apr 2026 06:11:02 +0000 Subject: [PATCH] docs(spec): document GitWorktreeSandbox, ContextTierHydrator, and idempotent execute dispatch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Minor clarifications documenting implementation details discovered from merged PRs. Changes: 1. GitWorktreeSandbox implementation details (Issue #6958, PR #5998): - Added 'Implementation class: GitWorktreeSandbox' note to §Sandbox Implementation Strategies - Documents worktree path (.worktrees/plan-) and branch naming (cleveragents/plan-) - Documents non-git fallback: filesystem_copy strategy using shutil.copy2 2. Idempotent execute dispatch (Issue #6958, PR #5998): - Added idempotency note to _cleveragents/plan/execute in §Complete Method Routing - Prevents duplicate dispatch errors in multi-agent scenarios 3. ContextTierHydrator (Issue #6953, PR #4219): - Added new §Context Tier Hydration subsection after §Three Storage Tiers - Documents ContextTierHydrator component: file discovery, fragment creation, injection point - Documents constructor injection pattern (no get_container() calls) - Documents sandbox root path (.cleveragents/sandbox/) - Added ContextFragment metadata type constraint warning (strings required in metadata dict) All changes are minor clarifications — no new architectural decisions, no interface changes.
