+"""Inject ``model_config = ConfigDict(extra='forbid', populate_by_name=True)``
+into every generated Pydantic BaseModel class, and add Pydantic v2
+``Field(discriminator=...)`` annotations on tagged-union fields.

-OpenAPI spec lacks `additionalProperties: false`. Springdoc never emits
+OpenAPI spec lacks ``additionalProperties: false``. Springdoc never emits
 that key, so we patch every generated class here.
 
-This implements policies P1 (response extras forbidden) and P2 (request
-extras forbidden) from `mini/cowork/design/040-codegen-policies.md`.
+Why ``populate_by_name=True``?
+==============================
+Without it, models with ``validation_alias=camelCase`` reject snake_case
+kwargs because ``extra='forbid'`` treats them as unknown keys. Setting
+``populate_by_name=True`` lets callers pass *either* the wire alias
+(``frequencySeconds=60``) *or* the Python field name
+(``frequency_seconds=60``), which makes the SDK feel like a proper
+Python library instead of a thin JSON wrapper. Implements P1.Bug5 from
+the round-3 DevEx audit.
+
+Why discriminator injection?
+============================
+Many request bodies (``CreateAssertionRequest.config``, alert channel
+configs, etc.) are *tagged unions*: every member has a
+``type: Literal["..."]`` (or ``channel_type``, ``check_type``, …) field
+that uniquely identifies which subtype applies. Without
+``Field(discriminator='type')``, Pydantic tries every union arm in turn
+and emits an error per arm — for the 41-member assertion union, that's
+**161 errors** for a single bad ``operator`` field. With the
+discriminator, Pydantic routes to the correct subtype based on the tag
+value and reports only that subtype's errors (typically 1).
+Implements P0.Bug4 from the round-3 DevEx audit.
 
-The transform is purely syntactic: scan each line, find `class Foo(BaseModel):`
-or `class Foo(RootModel[...]):` and inject `model_config = ConfigDict(...)`
-on the next non-empty indented line.
+This implements policies P1 (response extras forbidden) and P2 (request
+extras forbidden) from `mini/cowork/design/040-codegen-policies.md` plus
+the two DevEx fixes above.
 
-Idempotent: skips classes that already declare `model_config`.
+The transform is purely syntactic so we can run it on the codegen output
+without parsing Python AST. Idempotent: re-runs upgrade an existing
+``model_config`` line in place if it's missing the populate_by_name flag
+and skip unions already wrapped in ``Annotated[..., Field(...)]``.
