Sandbox/ModelFork/Prod/AcmeCare/PatientModel: Difference between revisions

* '''Last synced:''' v1.0.0 (behind by 1 major version)

! Field !! Type !! Origin

{{Field|model=PatientModel_AcmeCare|section=Identity|name=gender|type=String(1)|notes='''Kept''' — upstream removed in v2.0.0; AcmeCare still requires it}}

== How the sync works ==

A sync operation pulls in upstream changes without touching custom fields. Here is the step-by-step procedure:

=== Step 1 — Diff upstream ===

Compute the delta between the upstream version you last synced from (v1.0.0) and the target version (v2.0.0):

! Change !! Upstream v2.0.0

| '''Added''' || <code>blood_type</code>, <code>preferred_language</code>

| '''Removed''' || <code>gender</code>

| '''Modified''' || <code>phone</code> → required

| '''Unchanged''' || <code>patient_id</code>, <code>first_name</code>, <code>last_name</code>, <code>date_of_birth</code>, <code>email</code>, <code>address</code>

=== Step 2 — Evaluate each change ===

{| class="wikitable"

! Change !! Conflict? !! Decision

|-

| Add <code>blood_type</code> || None — new field, no collision || '''ADOPT''' — add to table

|-

| Add <code>preferred_language</code> || None — new field, no collision || '''ADOPT''' — add to table

|-

| Remove <code>gender</code> || '''Yes''' — AcmeCare has and uses this field || '''DECLINE''' — keep gender, document divergence

|-

| Make <code>phone</code> required || '''Yes''' — AcmeCare currently allows optional phone || '''PARTIAL''' — require for new patients only; existing stay optional

|-

| <code>patient_id</code> through <code>address</code> || None — unchanged || Inherit automatically

|-

| '''Custom fields''' (insurance_provider, insurance_id, primary_care_physician) || None — upstream doesn't know about them || '''Preserved automatically'''

|}

=== Step 3 — Apply ===

Edit this page's field table to reflect the decisions: add the adopted fields, update the phone constraint note, and bump the "Last synced" version to v2.0.0. Custom fields stay in the table untouched. The resulting model after sync:

{| class="wikitable"

! Field !! Type !! Origin

|-

| <code>patient_id</code> || UUID || Upstream v1.0.0+

|-

| <code>first_name</code> || String(100) || Upstream v1.0.0+

|-

| <code>last_name</code> || String(100) || Upstream v1.0.0+

|-

| <code>date_of_birth</code> || Date || Upstream v1.0.0+

|-

| <code>gender</code> || String(1) || '''Kept''' (upstream removed in v2.0.0)

|-

| <code>phone</code> || String(20) || Required for new patients (upstream made required)

|-

| <code>email</code> || String(254) || Upstream v1.0.0+

|-

| <code>address</code> || Text || Upstream v1.0.0+

|-

| <code>blood_type</code> || String(5) || '''Synced from upstream v2.0.0'''

|-

| <code>preferred_language</code> || String(50) || '''Synced from upstream v2.0.0'''

|-

| <code>insurance_provider</code> || String(100) || '''Custom — preserved'''

|-

| <code>insurance_id</code> || String(50) || '''Custom — preserved'''

|-

| <code>primary_care_physician</code> || String(100) || '''Custom — preserved'''

|}

=== Why custom changes never break ===

Because each fork is its own wiki page:

* Upstream fields and custom fields live in the same table — there is no separate "override file" that can get stale

* A sync is just a page edit: add new rows, update notes on changed rows, leave custom rows alone

* Upstream removal of a field has zero effect on the fork — the fork simply chooses not to delete the row

* There is no automated merge, no rebase, no conflict markers — every decision is explicit and recorded in the page history

This is the wiki equivalent of a '''manual three-way merge''' where the fork author is the resolver.

== Upstream v2.0.0 — sync decision table ==

{| class="wikitable"

! Upstream change !! Decision !! Rationale

|-

| <code>blood_type</code> (new) || '''ADOPT''' || Valuable clinical field, no conflict

|-

| <code>preferred_language</code> (new) || '''ADOPT''' || Needed for patient communications

|-

| <code>gender</code> (removed) || '''DECLINE''' || Billing system requires it

|-

| <code>phone</code> → required || '''PARTIAL''' || Required for new patients; existing grandfathered
