# Session notes — 2026-09-23

Working notes for the `feat/waves-11-13` line (CR-019, CR-020 reserved, D18),
written up before merge. Not a spec document — `wave-11.md`, `wave-13.md` and
`decisions-2026-09-17.md` are the source of truth for scope and acceptance
criteria. This is the "what actually happened building it" record.

## What shipped today

**CR-019 (wave 11) — usage/activity metrics, T11.1 through T11.6 complete:**

- `UsageEvent` table + migration (T11.1), a capture endpoint wired into
  `auth-guard.js` so every protected page pings it once per load, plus a
  `login` event at Okta sign-in (T11.2).
- `GET /api/usage/summary` (T11.3) — active users by day/week/month,
  per-user last-active, per-tool breakdown, filterable by date/project/
  user/tool, all combinable.
- `GET /api/usage/export` (T11.4) — raw and sanitized CSV. Sanitized mode
  replaces the username with an HMAC-SHA256 pseudonym (keyed with
  `auth.SECRET_KEY`), stable per user across rows and across separate
  export calls, so an external tool (Power BI etc.) can still group by
  user without ever seeing a real name.
- A new "Activity & usage" card in the admin console (T11.5): real filter
  controls, the summary tables, both export buttons. Client-side gated
  admin-only same as the rest of the console; the API underneath is
  independently gated server-side regardless.
- Retired the old per-browser "Usage logs" panel and `wp-usage.js`
  entirely (T11.6) — it had no reader left and was never a real data
  source for the new report anyway. The scattered `track()` call sites in
  the creator and wizard were left in place calling a documented no-op,
  rather than deleting ~45 individual call sites for the same effect.

Only **T11.7 (final wave verification)** is left before wave 11 is fully
closed out — everything under it has already been verified per-task, so
this is a consolidation pass, not new work.

**D18 (wave 13) — Okta/AD deprovisioning, T13.1 only:**

- Session lifetime changed from one flat `AUTH_SESSION_HOURS` to a sliding
  idle timeout (`AUTH_IDLE_MINUTES`, default 30) capped by a hard ceiling
  from original sign-in (`AUTH_SESSION_HOURS`, default 8, meaning changed
  from "session length" to "absolute ceiling"). Both defaults are flagged
  in `.env.example` and `DEPLOYMENT.md` as proposed, not confirmed against
  the tenant's actual Okta SSO policy.
- **T13.2 onward (the actual Okta Management API sync job) is paused** —
  explicit call from Matt: no Okta API credential yet, come back to it
  later. Not started, not blocked on anything code-side.

**CR-020 (wave 12, bulk user editing):** not started. Reserved, scoped in
`wave-12.md`, no code touched.

## Environment work (not itself a task, but load-bearing)

- Fixed a CRLF/LF mismatch that was making every tracked file look modified
  to this session's git client (`core.autocrlf true`, repo-local, no file
  content changed).
- This machine had no Python. Installed it via `winget` (`Python.Python.3.12`)
  and set up a `.venv` in the repo with `server/requirements.txt` installed,
  specifically so `tests/baseline_shots.py` could run locally — this
  sandbox has no headless-capable browser and can't download one (network
  allowlist), so the 390px/1440px screenshot verification CLAUDE.md asks
  for had to run on Matt's own machine instead, using the browser already
  installed there (Edge).
- Established a repeatable local verification loop for every task: throwaway
  SQLite, fake-Okta sign-in, promote to admin, `seed_demo.py` +
  `smoketest.py` (27/27 passing throughout), plus `baseline_shots.py` for
  anything touching `html/`.

## Standing constraints, still in effect

- Everything stays local on this branch line. No `git push` at any point
  today.
- One task per PR discipline was kept even though all of it landed on one
  branch — each commit corresponds to exactly one task ID, in wave order,
  each individually verified before the next started.

## Before merging

- Run T11.7 (full wave-11 verification pass) and record it in `wave-11.md`.
- Decide where this branch actually merges to — `feat/waves-11-13` has all
  of today's commits already; this notes branch was cut from it so it can
  fast-forward back in, or merge as its own PR if the notes should be
  reviewed separately from the code.
- T13.2+ and all of wave 12 remain explicitly out of scope until Matt says
  otherwise.
