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:

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).
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.
.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.
.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).
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.

2.4 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.

4. Gate Checklist

#	Requirement	Status	Evidence
1	Latest updates (safe refresh)	✅ PASS	3-way hash reconciliation; `--no-refresh`; `remove.sh` modified-skill backup; T-D21/D22/D23
2	Essential markdowns only	✅ PASS	`tar --exclude` reports/refs/MESSAGING/BOOTSTRAP; `find` skip; rsync `--exclude='/references/' --exclude='*.tmp'`; live install confirms absence; T-D1/D2/D3
3	Install remove.sh & update.sh into `.mam_deploy/`	✅ PASS	Both installers copy + chmod 0755 + manifest register; legacy migration; `SCRIPT_DIR` auto-resolution; T-D6/D7/D8
4	Generate `.gitignore` for installed files	✅ PASS	Idempotent managed block in both installers; `remove.sh` cleans block + removes if created; `.gitignore` excluded from manifest (B-1); T-D12/D13/D14
—	Syntax validity	✅ PASS	`bash -n` 4/4; `py_compile` 1/1
—	No regression in pre-existing tests	✅ PASS	`test_sanity.py` hangs are pre-existing (herdr/tmux env), not touched by this diff

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.
