Namespaced (distinct topic; GURU-5070 already authored 2026-05-25-session.md today, and this machine has a separate 2026-05-25-beast-chrome-fetch-and-identity-audit.md).

Session Summary

Picked up GURU-KALI's "RMM re-audit #2" handoff (coord message; 45 findings, 0 CRITICAL, 5 HIGH, 6 MEDIUM) and worked it end to end under the coordinator model: read the full report, claimed a coord lock, then triaged and remediated via the Coding Agent + mandatory Code Review Agent. The audit branch (audit/2026-05-25-rmm-audit-2) was docs-only — the fixes were recommendations to implement. All work landed on a new gururmm branch fix/audit-2-remediation (pushed, NOT merged, NOT deployed).

Triaged all findings into gururmm/docs/FEATURE_ROADMAP.md as BUG-002..BUG-012 and brought the report + UI_GAPS delta onto the branch. Implemented the safe, well-specified HIGH fixes: #1 crash detection (re-keyed health.rs from the never-emitted update_applied to update_success, converted that query + increment_crash_count to runtime sqlx to avoid a .sqlx cache break and chip at the BUG-007 macro MEDIUM, dropped the paired total_attempts double-count, added 2 #[sqlx::test] regression tests) and #5 (update_channel — found it IS read by 3 dashboard pages, so ADDED it to the server SELECTs rather than dropping from TS). Code Review returned REQUEST-CHANGES on one item: the migration-046 header-comment fix would itself break sqlx::migrate!'s checksum on the already-applied migration — the exact outage class the audit flagged — so it was reverted; the rest was approved.

Hardened build-server.sh (#2/BUG-003) on the branch — build lock + previous-binary backup + auto-rollback on failed is-active — and documented that the outage-causing script is the divergent webhook copy at /opt/gururmm/build-server.sh (unchecked git reset), which still needs reconciling. Mid-session, Mikes-MacBook-Air sent a deploy-coordination coord message; replied with a HOLD recommendation and three hazards (046 already applied in prod, the feature is inert, the server build script is unhardened).

For #3 (update_rollouts), Mike chose option (b): keep the feature inert and clearly labeled now, move the automated health-gated promotion (a) to the roadmap as a Phase-2 item that must be re-spec'd. Implemented the label via a code comment at resolve_agent_channel + roadmap entries, and reconciled the four Phase 5/6 docs in the ClaudeTools repo with a "feature inert" banner (this sync hit a rebase conflict from a concurrent GURU-5070 edit — resolved keeping both sides).

Finally, with build-server access granted, investigated #4 (Mac builds "40 behind"). The audit was wrong: the trigger is not broken — build-mac.sh is an intentional stub (no Mac build machine), the webhook invokes it every push and it no-ops, and Mac builds were never implemented in this pipeline. Corrected BUG-005 from HIGH "trigger broken" to LOW "unimplemented stub — product decision," and notified GURU-KALI.

Key Decisions

• #5 update_channel: ADD to server, not drop from TS — grep showed it's read by AgentDetail/ ClientDetail/SiteDetail; the column already exists (migration 026), so adding to the SELECT is zero-risk and preserves working UX.
• Reverted the migration-046 comment fix — editing an already-applied migration changes its sqlx checksum and fails sqlx::migrate! at startup (BUG-003 outage class). Left 046 byte-for-byte intact; marked won't-fix. Same hazard blocks the scaffolding-label-in-046-header idea.
• #3 = option (b) (Mike) — keep update_rollouts/health metrics inert + labeled (code comment + roadmap), defer automated gating (a) to a Phase-2 roadmap item requiring a full re-spec. Rationale: (a) adds a failure mode to an already-fragile pipeline, depends on the unmerged/unverified #1 signal, and is undesigned work — not safe to rush mid-deploy.
• Recommended MacBook HOLD the deploy — not a git conflict (work is on a branch), but 046 is already applied in prod, the feature is inert, and the server build script is unhardened.
• #4: corrected rather than "fixed" — verified via SSH the trigger fires and stubs out; Mac was never built and no runner is configured. Re-triggering (the audit's rec) is a no-op. Did not provision hardware or advance last-built-commit-mac artificially (would falsely claim a build).
• Used the Coding Agent + Code Review Agent for the production Rust changes (coordinator model); did doc/triage edits and the bash hardening directly.

Problems Encountered

• Migration-046 checksum hazard (caught in review) — the cosmetic header fix would reproduce the outage. Reverted (8ef8159); the applied migration is untouched.
• Rebase conflict during the ClaudeTools sync — GURU-5070 concurrently edited verify-rollout- system.sh (renamed host Saturn→gururmm-build) and a prior auto-sync had bumped the gururmm submodule pointer. Resolved: kept both the rename and my banner; kept the submodule at 938fa33 (gururmm main tip — a legitimate advance, not my branch).
• No SSH key access to the build server from BEAST (Permission denied (publickey,password)). Resolved using the vaulted password over paramiko for read-only commands.
• .sqlx macro cache risk in the #1 fix — changing an inline SQL literal in a sqlx::query! macro would break the offline build. Resolved by converting that query to runtime sqlx (also addresses part of BUG-007).

Configuration Changes

gururmm repo — branch fix/audit-2-remediation (origin azcomputerguru/gururmm):

• server/src/updates/health.rs — crash-detection fix (update_success), runtime-sqlx conversion of 2 queries, dropped total_attempts double-count, 2 new #[sqlx::test] tests; 2 stale .sqlx cache files removed.
• server/src/db/agents.rs — added update_channel: Option<String> to Agent/AgentResponse/ AgentWithDetails + both list SELECTs.
• server/src/db/updates.rs — scaffolding comment at resolve_agent_channel (health gating NOT wired; Phase-2).
• server/migrations/046_safe_rollout.sql — header edit made then REVERTED (untouched, intact).
• build-server.sh — build lock + binary backup + auto-rollback (BUG-003 hardening).
• docs/FEATURE_ROADMAP.md — BUG-002..012; BUG-004 decision (b); BUG-005 corrected; safe-rollout Phase-2 roadmap item.
• docs/UI_GAPS.md, reports/2026-05-25-rmm-audit-2.md — brought from the audit branch.

ClaudeTools repo (main):

• PHASE_6_TEST_PLAN.md, PHASE_5_COMPLETE.md, IMPLEMENTATION_SUMMARY.md, verify-rollout-system.sh — [WARNING] STATUS banner (feature inert / Phase-2 aspirational).
• Submodule pointer projects/msp-tools/guru-rmm advanced to 938fa33 (gururmm main tip).

Credentials & Secrets

• Build server SSH: guru@172.16.3.30:22 (Ubuntu 22.04, "gururmm-build"). Password (and same sudo password) is vaulted at infrastructure/gururmm-server.sops.yaml field credentials.password — value not reproduced here. Retrieved via the vault wrapper and used over paramiko for read-only commands only; no server changes made.
• No new credentials created or rotated this session.

Infrastructure & Servers

• Build/prod server: 172.16.3.30 (gururmm-build, Ubuntu 22.04). Gitea: azcomputerguru/gururmm.
• Build pipeline: /opt/gururmm/ — build-shared.sh (version bump + repo sync from /home/guru/gururmm, change-gate), build-linux.sh, build-windows.sh, build-mac.sh (STUB), webhook-handler.py; logs /var/log/gururmm-build{,-linux,-windows,-mac}.log. build-agents.sh is a deprecated wrapper. last-built-commit-{mac=1ed5596, linux/windows=373c5ce}.
• gururmm main tip: 938fa33 (deployed server was v0.3.22 at audit time / 3dcb30e).
• Coord API: http://172.16.3.30:8001/api/coord.

Commands & Outputs

• Read audit report: git -C projects/msp-tools/guru-rmm show origin/audit/2026-05-25-rmm-audit-2:reports/2026-05-25-rmm-audit-2.md.
• SSH (read-only) via paramiko: paramiko.SSHClient().connect("172.16.3.30",22,"guru",<vault pw>); ran cat/grep/git rev-list only.
• Mac log confirmed stub no-op: /var/log/gururmm-build-mac.log → 24+ "Mac build: no build machine configured, skipping" on 2026-05-25.
• Agent gap since last mac build: git -C /home/guru/gururmm rev-list --count 1ed5596..HEAD = 48 total, -- agent/ = 5.
• Build verification (on BEAST): cargo build (SQLX_OFFLINE) clean; #[sqlx::test] compile clean but need a live DB to run (pending on build server).

Pending / Incomplete Tasks

• Branch fix/audit-2-remediation not merged / not deployed — awaiting Mike's review + merge.
• Run the 2 #[sqlx::test] crash-detection tests against a live DB (build server) — they only compile offline here.
• #2 server-side: reconcile the divergent /opt/gururmm/build-server.sh (unchecked git reset) with the hardened repo copy, then deploy — needs SSH + sign-off.
• #3 (a): safe-rollout automated gating — Phase-2 roadmap item, MUST be re-spec'd before implementation (depends on #1 merged + verified).
• #4 decision: (A) ship Mac agents (provision Apple HW / osxcross + implement build-mac.sh + signing) or (B) defer + quiet the freshness alarm (treat stubbed platform as N/A).
• #6 MEDIUMs + LOWs (BUG-007..012): open.
• MacBook deploy: flagged HOLD; go/no-go is Mike's.
