# Cross Code Review Report — Job 384b7986
|
||
|
||
- **Job ID**: 384b7986
|
||
- **Reviewer**: cline (session: herdr:canary-projects-multi-agent-mux-creator-cline)
|
||
- **Target**: Improve deployment files in `deploy/*` (4 requirements: latest updates / essential markdowns only / install remove.sh & update.sh into `{workspace}/.mam_deploy/` / generate `.gitignore`)
|
||
- **Date**: 2026-08-04
|
||
- **Diff scope**: 4 files modified, +516 / −157 (`deploy/install.sh` +373/−, `deploy/install_mam.sh` +96/−, `deploy/remove.sh` +152/−, `deploy/update.sh` +52/−). New untracked test suite `tests/test_deploy_layout.py` (5 tests, T-D1→T-D28).
|

|
||
|
||
## 1. Summary
|
||
|
||
The changeset refactors the MAM deployment scripts into a Rev.2 layout that satisfies all four stated requirements. The implementation is cohesive, idempotent, and backward-compatible:
|
||
|
||
1. **Latest updates (safe-refresh)** — `deploy/install.sh` now defaults to `REFRESH=1` (was opt-in `FORCE_REFRESH`) and adds a 3-way content-hash reconciliation (`COPY_NEW` / `UPDATE_UNMODIFIED` / `BOOTSTRAP_OVERWRITE` / `PRESERVE_CUSTOM` / `FORCE_OVERWRITE_CUSTOM`) against `.mam/asset_hashes.txt`. User-modified framework skills are preserved and backed up to `.mam/skill-backups/<TS>/` unless `--overwrite-custom` is passed. A `--no-refresh|--offline` flag is added for air-gapped reinstalls. `remove.sh` now backs up locally-modified skills to `.mam-skill-backup.<TS>/` before deletion (mirroring install-side preservation).
|
||
|
||
2. **Essential markdowns only** — Archive/git fetch excludes `.agents/reports/*`, `.agents/references/*`, `MESSAGING.md`, `BOOTSTRAP.md`, `BOOTSTRAP.ko.md` via `tar --exclude` and `find ... *.tmp|*.log|*.pyc` skip. Default root docs limited to `AGENTS.md` (`MAM_INSTALL_DOCS=minimal`); `INSTALL.md` placed under `.agents/`. The separate `install_mam.sh` rsync gains `--exclude='/references/' --exclude='*.tmp'` (previously only excluded `.git/`, `/reports/`, `*.log`, `__pycache__/`, `*.pyc`). Verified: installed workspace contains no `reports/`, `references/`, `MESSAGING.md`, or `BOOTSTRAP.md`.
|
||
|
||
3. **`.mam_deploy/` layout** — `install.sh` and `install_mam.sh` both now copy `deploy/remove.sh` and `deploy/update.sh` into `.mam_deploy/` (chmod 0755, registered in manifest). Legacy root-level `remove.sh`/`update.sh` are migrated into `.mam_deploy/` if manifest-owned. `remove.sh` and `update.sh` gain `SCRIPT_DIR`-based auto-resolution: when invoked from inside `.mam_deploy/`, they target the parent workspace; when passed `.mam_deploy` as the target arg, they normalize to its parent. `update.sh` uses dual-resolution (`REMOVER` loop over `.mam_deploy/remove.sh` then `remove.sh`) before invoking the uninstaller.
|
||
|
||
4. **`.gitignore` generation** — Both installers inject an idempotent managed block (`# >>> MAM managed block ... <<<`) via a Python filter that removes any stale block before re-inserting. Block covers `/.venv/`, `/.mam/`, `/.mam_deploy/`, `/.mam.env`, `/.mam.env.*`, `!/.mam.env.example`, `/.cache/multi-agent-mux-monitor/`, `/.mam-skill-backup.*/`, `CURRENT_JOB.md`. `remove.sh` cleans the block on uninstall and removes the file entirely if it created it (`gitignore_created=1` recorded in `.mam/install_state`). `.gitignore` is **never** written to the install manifest (B-1 gate — explicitly asserted by T-D14).
|
||
5. **State preservation across updates (B-5)** — `update.sh` now stages and restores `install_state`, `asset_hashes.txt`, `version.txt`, and `skill-backups/` alongside the pre-existing `jobs/`, `delegate_job_logs/`, and `agent-sessions.*` — verified by T-D27/T-D28.

|
||
### 2.3 Live install inspection (clean temp workspace, `MAM_REPO_URL=. MAM_SKIP_VENV=1`)
|
||
```
|
||
--- .gitignore (managed block) ---
|
||
# >>> MAM managed block (managed by install.sh — do not edit) >>>
|
||
/.venv/ /.mam/ /.mam_deploy/ /.mam.env /.mam.env.* !/.mam.env.example
|
||
/.cache/multi-agent-mux-monitor/ /.mam-skill-backup.*/ CURRENT_JOB.md
|
||
# <<< MAM managed block <<<
|
||
|
||
--- .mam_deploy/ --- remove.sh (0755) update.sh (0755)
|
||
--- root files --- .gitignore .mam.env .mam.env.example AGENTS.md (no MESSAGING/BOOTSTRAP)
|
||
--- exclusions verified --- .agents/reports/ absent .agents/references/ absent MESSAGING.md absent BOOTSTRAP.md absent
|
||
--- .mam/install_state --- gitignore_created=1
|
||
--- .mam/version.txt --- source=<local> commit=2ff8b2c... fetched_at=20260804T131420Z method=local
|
||
--- manifest B-1 gate --- .gitignore NOT in manifest (PASS) .mam_deploy/remove.sh in manifest .mam_deploy/update.sh in manifest
|
||
```
|
||
|
||
### 2.4 Pre-existing test status (out of scope)
|
||
`tests/test_sanity.py` HANGS (timed out at 30s) — requires live `herdr`/tmux environment. **Pre-existing**, not modified by this changeset. No regression introduced.
|
||
---
|
||
|
||
## 3. Findings
|
||
|
||
### 3.1 Blocking defects — NONE
|
||
No syntax errors, no control-flow breaks, no manifest-corruption paths. All 4 requirement gates are satisfied and covered by passing tests.
|
||
|
||
### 3.2 Non-blocking follow-ups (informational, do not block merge)
|
||
|
||
**R-1 (Low) — Stray untracked `.tmp` file not covered by repo `.gitignore`**
|
||
A runtime artifact `multi-agent-mux-delegate-job.13436_75009.tmp` exists untracked under `.agents/skills/multi-agent-mux-delegate-job/`. The install-time `find` skip (`*.tmp` at install.sh:188) and `install_mam.sh` rsync `--exclude='*.tmp'` (line 118) correctly prevent it from being *installed* into target workspaces, but the **source repo's own `.gitignore`** has no `*.tmp` rule, so it keeps reappearing as an untracked file across reviews (also flagged in jobs `9c44c6b2` and `54413a8a`). Recommend adding a top-level `*.tmp` ignore to the repo `.gitignore` or cleaning the artifact at source. **Does not affect installed workspaces.**
|
||
|
||
**R-2 (Low) — `update.sh` legacy-restore ordering hazard on legacy-owned `.env`**
|
||
In `update.sh` lines 207–209, when `MAM_LEGACY_ENV_OWNED=1` and `ENV_BACKUP_SRC=.env`, the restore does `mv -f "$ENV_BACKUP_TMP" ".mam.env"` — correct file migration. The pre-capture of `MAM_LEGACY_ENV_OWNED` + `export` (lines 86–90) is correctly inherited by the child `install.sh`, which reads it in `migrate_legacy_env()` (install.sh:476). **Edge case:** the child installer runs in step 4 *before* the parent restore in step 5. The child sees no `.env` (moved to `.env.update-tmp`) and no `.mam.env`, so it creates a fresh default `.mam.env`. The parent's restore then sees `.mam.env` already exists and falls to the `else` branch (`mv -f "$ENV_BACKUP_TMP" "$ENV_BACKUP_SRC"` = `.env`), leaving the user's real config at `.env` while a fresh default `.mam.env` shadows it. This only manifests when updating a workspace whose config is still legacy `.env` AND MAM-owned. Recommend either (a) restoring the env backup *before* invoking the child installer, or (b) having the child installer skip env creation when `MAM_LEGACY_ENV_OWNED=1` and a `.env.update-tmp`/`.mam.env.update-tmp` sentinel exists. Not exercised by the current test suite (T-D27/T-D28 use `.mam.env`, not legacy `.env`).
|
||
|
||
**R-3 (Info) — `remove.sh` deletes `.mam_deploy/update.sh` unconditionally**
|
||
`remove.sh:307` calls `delete_asset ".mam_deploy/update.sh"` outside the manifest-ownership loop used for `remove.sh`. In practice `update.sh` is always in the manifest (both installers register it), so this is fine, but it's a minor asymmetry: `remove.sh` self-deletion is guarded by manifest/`FORCE` while `update.sh` is deleted unconditionally. Harmless given current installers always register `update.sh`; a one-line comment would aid future maintainers.
|
||
|
||
**R-4 (Info) — `install_mam.sh` does not write `install_state` / `asset_hashes.txt` / `version.txt`**
|
||
`install_mam.sh` deploys skills via `rsync` but does not populate `.mam/install_state`, `.mam/asset_hashes.txt`, or `.mam/version.txt`. Consequently a subsequent `install.sh --no-refresh` would treat all files as `BOOTSTRAP_OVERWRITE` (no `db_sha`), and `remove.sh`'s `GI_CREATED` lookup would default to 0. The primary installer is `install.sh`; `install_mam.sh` is a secondary path. Not a regression (it never wrote these files before). Documenting the divergence would help.

## 5. Verdict
|
||
|
||
The changeset is well-structured, addresses all four requirements with idempotent and backward-compatible logic, and is backed by a passing 5-test suite covering the critical gates (essential-docs filtering, `.mam_deploy/` layout, `.gitignore` managed block + manifest exclusion, safe-refresh custom-skill preservation, and update-cycle state preservation). The 4 non-blocking follow-ups (R-1 through R-4) are low severity and do not impede merge. No blocking defects found.
