docs: explain and demonstrate Conditions across the API - #258
Conversation
Conditions were barely documented: Read and StreamedListObjects never mentioned them at all, and none of the worked JSON examples for Write/Check/ListObjects/ListUsers/Expand/ReadChanges/BatchCheck showed a conditioned tuple in practice. Add message-level docs for Condition, ConditionMetadata, ConditionParamTypeRef, RelationshipCondition, TupleKey, TupleKeyWithoutCondition, and Tuple, and add a consistent worked example (a time-limited access grant) to every relevant RPC description, including verified behavior notes (context merge/override order, Expand's non-evaluation of conditions, ReadChanges stripping conditions on deletes).
The description fields render as Markdown, but many sentences were separated only by a single newline, which Markdown collapses into one run-on paragraph instead of distinct paragraphs. Add blank lines between logical points in Read/Write/Check/Expand/ListObjects/ ListUsers/ReadChanges/StreamedListObjects (also fixes two spots in ListUsers where sentences were concatenated with no separator at all). Kept as its own commit, separate from the condition content changes, so it can be reverted independently if it affects rendering once deployed.
Condition-related explanations in Check and Expand were split across non-adjacent paragraphs with unrelated content (authorization_model_id, consistency, response tree structure) sandwiched in between, making the condition story hard to follow. Reorder so all condition/context material for a given RPC is contiguous.
…gression
Several examples pointed elsewhere ("see the Write API docs for that
example") instead of restating the small amount of data needed
(grant_time/grant_duration values, or the condition/model signature) -
embed it directly so each example stands on its own. Also restructure
ListObjects and ListUsers, which jumped straight to a conditioned
example with no plain query shown first, to follow the same
typical -> conditioned -> contextual-tuple progression already used by
Write and Check. Adds a missing contextual_tuples example for
ListObjects and ListUsers (the latter uses a plain array, not a
tuple_keys-wrapped object, unlike Check/ListObjects/Expand).

ReadChanges returns TupleChange, not Tuple. The current text gives SDK users the wrong response shape.

Pull request overview
This PR improves the API’s documentation around ABAC/conditional tuples by expanding and reorganizing proto/RPC descriptions and synchronizing the generated Go/OpenAPI artifacts so conditions and context behavior are clearer for API consumers.
Changes:
- Adds/expands documentation for
RelationshipCondition,TupleKey,Tuple, and modelConditions to explain conditioned relationships and context usage. - Enhances RPC docs (Read/Write/Check/ListObjects/ListUsers/Expand/ReadChanges/BatchCheck) with clearer paragraphs and more self-contained examples.
- Updates generated artifacts (
*.pb.go,apidocs.swagger.json) to reflect the proto comment/example changes.

- This comment says deletes “ignore” any
condition, butWriteRequestDeletes.tuple_keysisTupleKeyWithoutCondition(no condition field). That makes the wording confusing for API consumers; it’s clearer to state that conditions aren’t supported/used for deletes.

This condition only enforces the expiration boundary, so it also evaluates to true before grant_time. Since the surrounding text describes a grant that starts at grant_time, could we use current_time >= grant_time && current_time < grant_time + grant_duration here (and in the corresponding examples), or revise the wording if pre-start access is intentional?

This list omits BatchCheck and StreamedListObjects, both of which accept request context and evaluate conditional tuples. Could we include them here and in the other new API enumerations so the generated documentation does not imply that conditions are ignored by those endpoints?

ReadChanges returns TupleChange entries (tuple_key, operation, and timestamp), rather than wrapping stored tuples in Tuple as Read does. Could we distinguish the two response shapes here so generated SDK/API documentation does not describe ReadChanges incorrectly?

Conditions/contextual tuples were barely documented across the API — Read never mentioned them at all, and none of the worked examples for Write/Check/ListObjects/ListUsers/Expand/ReadChanges/BatchCheck showed a conditioned tuple in practice. Also took the opportunity to add paragraph spacing throughout for better readability.
No behavior change — proto comments, doc-generation annotations, and generated docs only.
Summary
This adds message-level docs (Condition, RelationshipCondition, TupleKey, etc.) and a consistent worked example — a non_expired_grant time-limited access condition, matching the existing docs.openfga.dev example — to every relevant RPC.
