Add CODEX_AUTO_COMPACT_LIMIT (999_999_999) so Codex cannot compact recipe content out of the agent's context during long pipeline runs. Wire it through _is_autoskillit_registered and ensure_codex_mcp_registered (both normal and corrupt paths), plus the re-export chain and the test fixtures that build "valid config" dicts. Add a new PreToolUse guard `recipe_read_guard.py` that denies run_cmd/Bash commands containing recipe/skill/agent path patterns and run_python callables matching `autoskillit.recipe.*` in headless sessions. This is defense-in-depth that cannot be compacted away, unlike the prompt-based prohibitions in `_backend_supplement()`. Register the guard in HOOK_REGISTRY with matcher `Bash|mcp__.*autoskillit.*__(run_cmd|run_python)` and add it to NEW_SUBDIR_BASENAMES. Run `task sync-hooks-hash` to refresh registry.sha256.

…_guard Mirrors the pattern established in fleet_dispatch_guard.py — emit sys.stderr.write() on the fail-open path so silent OSError failures are observable in session logs without changing the fail-open contract.

Summary
Prevent Codex sous-chef sessions from losing recipe content during long pipeline runs by:
Disabling auto-compaction — Set
model_auto_compact_token_limit = 999999999in the Codexconfig.tomlviaensure_codex_mcp_registered(), using the existing_ensure_top_level_key()pattern already used fortool_output_token_limit.Structural recipe-read guard — Add a new blocking PreToolUse guard hook (
recipe_read_guard.py) that deniesrun_cmd/Bashcalls containing recipe/skill/agent file path patterns andrun_pythoncalls importingautoskillit.recipe.*. This provides defense-in-depth that cannot be compacted away, unlike the prompt-based prohibitions in_backend_supplement().Implementation Plan
