Routed the request through the `remediation-tool` skill against the Cascades M365 tenant (`cascadestucson.com`, `207fa277-e9d8-4eb7-ada1-1064d2221498`). + +The opening consent audit graded the tenant RED, reporting "app NOT consented (token mint failed)" for all four app tiers. That was a false negative. The wiki recorded that the Exchange Operator app had worked against this tenant as recently as 2026-06-12 (the `grievances@`/`Surveys@` shared-mailbox delegations), which contradicted the audit. Testing the token mint directly surfaced the real fault: `get-token.sh` resolves the vault from `~/.claude/identity.json`, but this machine's identity and `vault_path` (`D:/vault`) live in the repo at `.claude/identity.json`. With `VAULT_ROOT_ENV=D:/vault` the `exchange-op` token minted immediately. The tenant was fully consented the whole time. + +Read-only recon via the EXO REST `InvokeCommand` endpoint identified `accounting@cascadestucson.com` as a SharedMailbox ("Accounting Dept.", account disabled — normal for shared) and confirmed `accountingassistant@` is a distinct UserMailbox, not a delegate. The existing delegates — Lauren Hasselman, Ashley Jensen, Zachary Nelson — each held FullAccess + SendAs. The wiki independently records Chris Knight as "same access tier as Lauren Hasselman," so the grant pattern was unambiguous. + +After explicit user confirmation, applied `Add-MailboxPermission` (FullAccess, `InheritanceType All`, `AutoMapping $true`) and `Add-RecipientPermission` (SendAs) via the `exchange-op` tier. Both returned OK. The first verification read-back showed FullAccess but **not** SendAs — Exchange replication lag, not a failed write. A re-read confirmed Chris on the SendAs list, and the trustee GUID returned by the write (`a1f1bb9e-0cee-4a49-8397-189e6137d680`) matched his `ExternalDirectoryObjectId`. + +Closed out by updating `wiki/clients/cascades-tucson.md` with a new `accounting@` delegation record (delegates, grant pattern, replication gotcha) and a note on Chris's staff line. Logged two errorlog entries for the path-drift defects found along the way. + +## Key Decisions + +- **Did not trust the RED consent audit.** The wiki's 2026-06-12 record of a successful Exchange Operator write against this tenant contradicted it. Verifying the token mint directly was cheaper than acting on the audit — and acting on it would have meant emailing the client an admin-consent link they did not need. +- **Granted SendAs, not SendOnBehalf.** All three existing delegates hold SendAs; SendOnBehalf would render as "Chris Knight on behalf of Accounting Dept." to recipients and break parity with the rest of the accounting staff. +- **`AutoMapping $true`** was the specific mechanism the request required — "attached email account" means the mailbox self-attaches to the Outlook profile via AutoDiscover, rather than the user hand-adding it. +- **Re-read before declaring the SendAs write failed.** The write returned a trustee GUID; resolving that GUID against `Get-Mailbox` proved the grant landed and the read was stale. +- **Skipped a full `/wiki-lint` pass.** Two bullet edits to one existing article introduced no `[[wikilinks]]`. Ran the applicable checks (link integrity, article structure) instead of a whole-wiki scan. + +## Problems Encountered + +- **`consent-audit.sh` reported a false RED "app NOT consented" for all four tiers.** Root cause was a *local* vault-path lookup failure, not tenant consent. The script conflates "could not read the vault" with "tenant has not consented." Resolved with `VAULT_ROOT_ENV=D:/vault`. Logged to `errorlog.md`; the script should fail loud on a vault-path error rather than downgrading it to a consent finding. **This is the dangerous one** — the false negative points directly at sending a client an unnecessary consent link. +- **`get-token.sh` and peers read `~/.claude/identity.json`,** but the authoritative identity (with `vault_path`) is the repo's `.claude/identity.json`. Same path-drift family. +- **`.claude/commands/wiki-lint.md` hardcodes `cd D:/claudetools`,** but `claudetools_root` on this machine is `C:/claudetools`. Logged as `--friction`. +- **Post-write `Get-RecipientPermission` did not show the new SendAs trustee.** Exchange replication lag across replicas. Re-read confirmed. Recorded in the wiki so the next delegate-add does not misread this as a failure. + +## Configuration Changes + +| File | Change | +|---|---| +| `wiki/clients/cascades-tucson.md` | Added `accounting@` delegation record + grant pattern + replication gotcha (line ~291); appended accounting-mailbox note to Chris Knight's staff line (line ~214) | +| `errorlog.md` | 2 entries: `remediation-tool/consent-audit.sh` (false RED), `wiki-lint` (hardcoded path, `--friction`) | + +**M365 tenant changes (Cascades):** two permission grants on `accounting@cascadestucson.com` — see Commands below.

Highest-value of the three. +- **`get-token.sh` + sibling scripts:** resolve identity from repo `.claude/identity.json` (honoring `claudetools_root`), not `~/.claude/identity.json`.
