 ## Update: 16:30 PT — Discord Bot Phase 1.5, Tedards + Dataforth EOP investigations, cert auth on 5 MSP apps
 ### User
 - **User:** Mike Swanson (mike)
 - **Machine:** GURU-BEAST-ROG
 - **Role:** admin
 - **Session span:** ~2026-05-01 11:00 PT through ~16:30 PT (separate Claude Code session from the morning license-audit + breach-check + initial-Dataforth work that produced the prior section)
 ### Session Summary
 This update wraps up the Dataforth email issue the prior section left open, refactors the Discord bot from a hand-rolled Anthropic-SDK app into a Claude Agent SDK harness, generates and rolls out cert-based auth on all 5 MSP Entra apps, and corrects the prior section's incorrect claim that the EXO admin REST API does not expose `Get-MessageTraceV2`, `Get-QuarantineMessage`, `Set-MailboxJunkEmailConfiguration`, or related Tenant Allow/Block-List cmdlets. They are exposed — the prior session called them from the Security Investigator tier (which lacks the `Exchange.ManageAsApp` Graph permission), so EOP cmdlets returned 401. Calling the same `outlook.office365.com/adminapi/beta/{tenant}/InvokeCommand` endpoint from the **Exchange Operator** tier (which already has both `Exchange.ManageAsApp` and the Exchange Administrator directory role) works end-to-end. Joel Lohr's whitelist was applied via REST — `azlohr@comcast.net` added to Dataforth's Tenant Allow List for 90 days, and all 12 quarantined messages released to ghaubner and jantar. The previous session's PowerShell + cert-thumbprint workaround was a dead end based on a permissions misdiagnosis; the actual blocker was tier selection, not REST exposure.
 The Discord bot pivoted from "structured RPC client with three hand-written Anthropic tool definitions (`query_claudetools_api`, `run_breach_check`, `run_tenant_sweep`)" to "Claude Code in a Discord channel." `bot/claude/client.py` now wraps `claude-agent-sdk==0.1.72` with a per-thread `ClaudeSDKClient`; the workspace `cwd` is the ClaudeTools repo root and the system prompt is the verbatim contents of `.claude/CLAUDE.md`, so the bot inherits the same identity rules, mode triggers, vault patterns, and NO EMOJIS rule the interactive Claude Code does. Two architectural side decisions: (1) routed auth through the bundled CLI's local OAuth credential (Mike's Pro Max subscription) rather than the API key after the first turn hit the Tier-1 ITPM 10K limit on CLAUDE.md alone; (2) suppressed the streaming `[INFO] Using tool: X` notices that were cluttering the thread, because Discord orders messages by send-time and edits by edit-time, which placed the final-answer message at the top and a trail of tool-use notices below it. Discord-side @mention requirement was relaxed for follow-ups within bot-owned threads. Image/PDF/text attachments now download to a per-thread directory under `.attachments/<thread_id>/` (gitignored), get referenced by absolute path in the user message, and are wiped after the turn — 25 MB per-file, 100 MB per-turn caps. Bot is running as a background process on GURU-BEAST-ROG.
 The cert-auth refactor is the larger long-term change. Each of the five ComputerGuru MSP Entra apps (Security Investigator, Exchange Operator, User Manager, Tenant Admin, Defender Add-on) now has a self-signed RSA-2048 cert with 2-year validity (expires 2028-04-30) registered in `keyCredentials` alongside the existing client_secret in `passwordCredentials` (expires 2028-04-20). Both auth methods are now valid concurrently. The vault entries at `msp-tools/computerguru-{slug}.sops.yaml` carry four new fields under the encrypted `credentials:` block: `cert_thumbprint` (SHA1 hex, drop-in for `Connect-ExchangeOnline -CertificateThumbprint`), `cert_thumbprint_b64url` (for OAuth `x5t` JWT header), `cert_expires`, and `cert_private_key_pem_b64` (base64-encoded PEM). `get-token.sh` was refactored (+225/-38) to prefer cert auth when the fields are present, fall back to client_secret when not, and accept a `REMEDIATION_AUTH=secret|cert` env var override. End-to-end verified for all three modes after token-cache wipe. A one-time scheduled remote agent (routine `trig_013415ZYng6zfJbXPX8ea4a3`) fires 2027-12-15T13:00:00Z to open an internal Computer Guru Syncro ticket reminding Mike to rotate the credentials before the spring-2028 expiry.
 Side findings worth keeping: the Tedards email issue (lindsay@agencyzoomify.com going to trash, only Lindsay, not other users at the same domain) was diagnosed without remediation — Lindsay sends "as agencyzoomify" from a separate boltonselect.com tenant, so DMARC alignment fails (envelope-from is boltonselect, From header is agencyzoomify, neither domain has DKIM, agencyzoomify has `p=quarantine`); the customer-facing fix is on Lindsay's IT, not Tedards's. Posted explanation as a Syncro comment on ticket #32228. Sync at end of session pulled three Howard commits (Syncro skill timer-entry-first refactor, three new feedback memory files including one for the Windows /tmp path issue we hit earlier in this same session) and pushed three local commits cleanly.
 ### Key Decisions
 - **Bot uses Pro Max OAuth, not the API key.** The vaulted Anthropic API key was on a low API tier (10K ITPM on Sonnet 4.6) and a single turn with the full CLAUDE.md as system prompt blew the limit. OAuth via the bundled Claude Code CLI's local credential store taps Mike's Pro Max subscription quota, which has far more headroom for an internal-team chat bot. Tradeoff: bot traffic now competes with Mike's interactive Claude Code in the same 5-hour usage window. Acceptable for a small MSP with two users. The API key stays vaulted as a fallback if metering becomes important later.
 - **Cert auth and client_secret coexist; no rotation of secrets.** Adding a cert is a strict superset — both auth methods work, no breakage risk if cert rollout has any issue. Client_secret stays valid through 2028-04-20 as a known-good fallback. Future-state can drop the secret once the cert flow has run for some time without issues.
 - **90-day expiry on the Dataforth allow-list entry.** Microsoft's `New-TenantAllowBlockListItems` accepts `ExpirationDate` up to 90 days max (or `NoExpiration: true` for permanent). 90 days gives Comcast time to fix their SPF (unlikely; their outbound posture has been a perennial issue) without leaving a permanent override that would mask future legitimate failures. Re-add expected.
 - **Renewal reminder at 2027-12-15, not earlier.** Cert expires 2028-04-30, secret 2028-04-20. Picked Dec 15 2027 because it's ~135 days out from secret expiry / ~137 days from cert expiry — both inside the 180-day "should rotate" window. Earlier dates miss the window; later dates leave less rotation lead time. Initial proposal of "~2026-12" was a typo — corrected to 2027-12.
 - **Corrected the prior section's "EXO REST API not exposed" claim.** Tested via Exchange Operator instead of Security Investigator; cmdlets work because the Operator tier already has `Exchange.ManageAsApp`. Recommended Option A (add `Exchange.ManageAsApp` to Security Investigator's manifest) for read-only EOP investigation paths going forward, but that's a separate task — not done in this session.
 - **Stopped posting `[INFO] Using tool: X` notices to Discord.** Discord orders messages by send-time, edits in place. The status message (which gets edited with the final streaming answer) was anchored at the top of the thread by send-time T0, so every tool-use notice posted as a new message at T1+ landed below the final answer. Tool-use feedback now goes only to server-side logs.
 ### Problems Encountered
 - **10K ITPM rate limit on first bot turn.** Resolution: routed bot through OAuth (Pro Max) instead of API key. Removed `ANTHROPIC_API_KEY` from `.env`; made it `Optional[str] = None` in `bot/config.py`. Bundled Claude Code CLI now reads `~/.claude/.credentials.json` for auth.
 - **Security Investigator returned 401 for EXO admin REST.** Token claims showed `aud=outlook.office365.com` and `roles=[full_access_as_app]` only — that role is the EWS-level mailbox-read permission, not the admin permission needed for `InvokeCommand`. Real fix is to add `Exchange.ManageAsApp` (`dc50a0fb-09a3-484d-be87-e023b12c6440`) to the Investigator manifest and re-consent across tenants. Workaround used in this session: ran the Dataforth investigation via Exchange Operator tier instead, which already has the permission. Filed as Option A in the EOP-permissions discussion; not yet implemented.
 - **Graph PATCH keyCredentials read-back showed stale data.** Eventual consistency — the immediate post-PATCH GET returned `keyCredentials=[]` for 4 of 5 apps, but a re-read seconds later showed all 5 with the new cert in place. PATCH returned 200 for all 5; the issue was the read replica, not the write. No retry needed.
 - **`pydantic-settings==2.3.0` blocked `claude-agent-sdk==0.1.72` install.** SDK requires `pydantic-settings>=2.5.2` (and `pydantic>=2.11.0`) because it pulls in `mcp>=1.19.0`. Loosened the pins in `requirements.txt` to `>=` ranges; `pydantic` resolved to 2.13.3.
 - **Discord tool-use notices appeared below the final answer.** Cause documented under Key Decisions. Fix: removed the Discord post; tool-use events now log server-side only.
 - **`Get-QuarantineMessage` rejected the `SenderAddress` parameter as a string.** Error: `Cannot convert value "azlohr@comcast.net" to type "System.String[]"`. Microsoft's typed-cmdlet wrapper expects an array. Fixed by wrapping in a JSON array (`["azlohr@comcast.net"]`).
 - **Ollama narrative draft for this /save pulled stale prior content.** Same bug Howard documented in `feedback_tmp_path_windows.md`: prior `/save` left `save_narrative_prompt.txt` in `%LOCALAPPDATA%/Temp`; my Write call rejected because the file already existed. The next `py` call read leftover prompt content and qwen3 produced a perfectly-coherent but wrong narrative about license audits. Resolution: explicit `rm -f` before `Write`. Worth fixing in the `/save` skill (delete-before-write or unique-per-session filename).

 ### Pending / Incomplete Tasks
 #### From this session
 - [ ] **Add `Exchange.ManageAsApp` to Security Investigator manifest** — Option A from the EOP-permissions discussion. One manifest field add in the home tenant, plus re-consent loop across all currently-onboarded tenants. Unlocks `Get-MessageTraceV2`, `Get-QuarantineMessage`, `Get-TransportRule`, `Get-HostedContentFilterPolicy`, etc. for the read-only Investigator tier (currently they only work via Exchange Operator, which is overprivileged for read paths).
 - [ ] **Optional: tighten Investigator's directory role from Exchange Administrator (read+write) to Security Reader (read-only)** — pairs with Option A above. Better hygiene; not blocking.
 - [ ] **Optional: clean up the `[DEBUG] on_message fired:` and `[DEBUG] Guild:` lines added to `bot/main.py`** — useful for troubleshooting the intent/permissions setup on first run, but noisy now. Currently committed.
 - [ ] **Optional: rotate the Discord bot token** — it transited this Claude conversation when Mike pasted it. Low urgency (private guild, internal-only bot), but belt-and-suspenders.
 #### Carried from morning section (still open)
 - [ ] **wwilliams password reset** — still requires manual Admin Center action.
 - [ ] **wwilliams MFA upgrade** — Authenticator app + remove email MFA.
 - [ ] **BG Builders / Kittle CSP verification** — Pax8 portal check.
 - [ ] **Kittle license renewal** — both subs expire 2026-05-31 (30 days).
 #### Followups proactively scheduled
 - 2027-12-15 — `trig_013415ZYng6zfJbXPX8ea4a3` fires; opens internal Syncro reminder for cert + secret rotation.
