+# Handoff / Resume Notes
+
+Read this first if you're picking this project back up — whether that's
+Claude Code in a future session or a human developer. The phase-by-phase
+build plan is in `CommunityOS_Implementation_Plan_for_Claude_Code.md`; this
+file is the "where things actually stand" companion to it.
+
+## Status at a glance
+
+| Phase | What it is | Status |
+|---|---|---|
+| 0 | Repo scaffold, Docker dev stack, CI + brand-leak guardrails | ✅ Done, committed |
+| 1 | `community_membership` | ✅ Done, committed |
+| 2 | `event_qr_ticketing` | ✅ Done, committed |
+| 3 | `community_school` | ✅ Done, committed |
+| 4 | `community_classifieds` + `community_benefits` | ✅ Done, committed |
+| 5 | `community_interac` (Interac e-Transfer payment provider) | ✅ Done, committed |
+| 6 | `community_theme_base` + `community_portal` | ✅ Done, committed |
+| 7 | `tncsc_deployment` (client config layer) | ✅ Done, committed |
+| 8 | TNCSC data migration scripts | 🟡 Barely started, **not committed** — see below |
+| 9 | Packaging for resale + production go-live | ⬜ Not started |
+
+Every phase 0–7 commit was verified against a **live** Odoo 19 + Postgres 16
+container before being committed — not just written and assumed to work.
+Run `git log --oneline` for the full commit list; each commit message
+documents what was built and how it was verified, including several real
+Odoo 19 API changes that don't match older docs/tutorials (see "Gotchas"
+below for the index).
+
+**No git remote is configured.** This repo only exists on this machine
+right now. Before handing off to a team, push it somewhere (GitHub/GitLab/
+etc.) — see "Handing off to a team" below.
+
+## Resuming the dev environment
+
+```bash
+cd deploy
+docker compose up -d
+```
+
+- Odoo: http://localhost:8069, database `communityos_dev`, login `admin` /
+  password `admin`.
+- This dev database has been used for **all** testing across every phase —
+  it has real posted accounting entries in it (from Interac transaction
+  confirmations, membership invoices, etc.). That's *why* Phase 7's
+  `tncsc_deployment` module can't be installed on it directly (Odoo
+  correctly refuses to change a company's currency once journal entries
+  exist) — it was instead verified on throwaway fresh databases
+  (`tncsc_freshN`, all dropped after verification). A real TNCSC production
+  database should be a genuinely fresh install, not this dev one.
+- **After any module code change**, the *running* `deploy-odoo-1` container
+  has a stale in-memory registry until you either upgrade the module (`-u`)
+  and restart the container, or just restart it:
+  ```bash
+  docker compose restart odoo
+  ```
+  This bit repeatedly during development — don't skip it when testing.
+
+## Phase 8 — exactly where it was left off
+
+Two files exist, committed as WIP (see the `wip:` commit), inert (not
+imported by anything, not installed, no manifest references them):
+
+- `scripts/_migration_common.py` — shared JSON-RPC helpers (auth, execute_kw,
+  CSV normalization, a `MigrationReport` class) for the migration scripts.
+  Finished, not yet tested against anything.
+- `scripts/migrate_members.py` — first pass at the member migration script
+  (idempotent upsert by email, dry-run flag, tier lookup by code, report
+  CSV). Written but **not tested at all** — no live run against Odoo yet.
+
+Still to do for Phase 8 (see the plan's Phase 8 section):
+- `scripts/migrate_students.py` — not started.
+- `scripts/migrate_opening_balances.py` — not started.
+- Test all three against synthetic/sample CSV data on a live instance,
+  the same way `scripts/migrate_classroom.py` was tested (see that file
+  and Phase 3's commit for the pattern: dry-run first, then a real run,
+  then a second real run to prove idempotency).
+- Real TNCSC member/student data doesn't exist yet — these scripts were
+  intentionally designed against a *documented, assumed* CSV schema (see
+  each script's docstring) since the real export format isn't known yet.
+  Confirm the assumed column names match the real export before relying on
+  them, or adjust the scripts to match.
+
+To pick this back up: either continue `migrate_members.py`'s testing and
+write the other two scripts, or decide the assumed CSV schemas are wrong
+and redesign first once real export samples exist.
+
+## Phase 9 — not started
+
+Two sub-parts with very different risk profiles:
+- **9-A (productize)**: static description pages, READMEs, CHANGELOGs,
+  release tagging for the product modules. Safe to do autonomously.
+- **9-B (go-live)**: SSL, DNS cutover, firewall rules, backups on a **real
+  production server**. This needs a human in the loop with actual server
+  access/credentials — don't let an agent run this unattended.
+
+## Gotchas discovered this build (Odoo 19 API drift + environment quirks)
+
+This Odoo 19 build (`19.0-20260817`, essentially a nightly) diverges from
+older tutorials/docs in several places that cost real debugging time. Each
+is documented in detail in the commit message where it was found — this is
+just the index so you know to search `git log` for it instead of
+re-discovering it:
+
+- `res.groups.category_id` → replaced by `privilege_id` →
+  `res.groups.privilege.category_id` (Session 1-A commit).
+- Settings pages use a new `<app>/<block>/<setting>` structure inherited
+  from `base.res_config_settings_view_form`, not the old raw-div layout
+  (Session 1-A commit).
+- `ir.cron` dropped `numbercall` entirely (Session 1-B commit).
+- `event.event` has no `state` field anymore (replaced by a
+  `stage_id`/`event.stage` kanban system) (Phase 2 commit).
+- Route `type='json'` should be `type='jsonrpc'` (`'json'` still works but
+  is deprecated) (Phase 2 commit).
+- Search-view `<group>` elements for "Group By" sections no longer accept a
+  `string` attribute, only `name` (Phase 3 / Phase 4 commits).
+- `res.groups.users` → renamed to `user_ids` (Phase 4 commit).
+- `res.config.settings` fields backed by `config_parameter=` only support
+  boolean/integer/float/char/selection/many2one/datetime — **not**
+  `Binary`. Using it on a Binary field breaks *every* Settings tab, not
+  just the one you're adding, since they share one model (`fix:` commit
+  after Phase 6).
+- Anonymous visitors hitting an `auth='user'` + `website=True` route in
+  this specific build crash with a raw 500 instead of a clean redirect to
+  `/web/login` (`Request._serve_db`'s `finally: self.env = None` runs
+  before the website error handler tries to build the redirect). Worked
+  around by switching those routes to `auth='public'` with a manual
+  `if request.env.user._is_public(): return request.redirect(...)` check
+  (`fix:` commit after Phase 6 — this is the fix to reach for if you add
+  *new* member-only pages later, don't reintroduce `auth='user'` on a
+  `website=True` route without it).
+- Setting `res.company.country_id` on a brand-new company auto-schedules
+  this build's own chart-template installer via a precommit hook, which
+  races an explicit `try_loading()` call made in the same install
+  transaction and silently reverts it afterwards. `ir.cron` code execution
+  is also sandboxed and forbids direct attribute assignment (`STORE_ATTR`)
+  — use `.write(...)`. Both fully explained in the Phase 7 commit message,
+  fix pattern is in `addons/tncsc_deployment/models/res_company.py`.
+
+## Handing off to a team
+
+1. **Push this repo to a real remote** (GitHub/GitLab/etc.) — right now it
+   only exists locally.
+2. Point them at `CommunityOS_Implementation_Plan_for_Claude_Code.md` (the
+   plan) and this file (current status).
+3. They'll need Docker Desktop (or equivalent) to run `deploy/docker-compose.yml`
+   locally — no other local dependencies.
+4. If they're using Claude Code to continue: just point it at this repo and
+   this file. It doesn't need conversation history — everything load-bearing
+   is either in a commit message or in this document.

+"""Migrate existing TNCSC members into Community OS Membership.
+
+Input CSV columns (source system export - adjust the header names below to
+match the real export once available, the column *names* are what matter,
+not their order):
+
+    full_name,email,phone,tier_code,membership_start,membership_expiry,is_volunteer
+
+  - full_name: required.
+  - email: required, used as the dedupe/match key.
+  - phone: optional, normalized to digits (with a leading + kept if present).
+  - tier_code: required, must match an existing community.membership.tier
+    code (e.g. IND, FAM, STU, SEN, LIFE for the TNCSC deployment).
+  - membership_start / membership_expiry: optional, several common date
+    formats are accepted and normalized to ISO (YYYY-MM-DD).
+  - is_volunteer: optional, "1"/"true"/"yes" (case-insensitive) = True.
+
+Behaviour:
+  - Rows missing full_name/email, with an unrecognized tier_code, or that
+    duplicate an email already seen earlier in the SAME file are marked
+    'failed' with a reason and skipped - they never reach Odoo.
+  - Existing members are matched by email (case-insensitive) and updated;
+    new ones are created. Re-running the same file is safe: it always
+    converges on the same end state rather than creating duplicates.
+  - A member with a tier and no explicit state that isn't already active
+    is activated (generates a member ID) after being created/updated.
