🦋 What this changes

The REST surface used two vocabularies for the same two concepts. Effects served their live-control writes under a current path segment while the sibling read routes already said active. Scene layer stacks hung off /groups/{group_id} while zone CRUD on the very same object used /zones/{zone_id}. Underneath the paths, a handful of payload fields still spelled a zone as a group. This wave makes the surface say one thing per concept.

Every old path is deleted rather than aliased. There is no redirect, no dual-accept, and no serde alias left behind, so a caller on an old spelling gets a 404. Spec 76's lockstep doctrine is what makes that safe: hypercolor ships the daemon and every in-repo client together, so all of them move here.

Names that follow the wire

update_current_controls and set_current_control_binding become their active spellings, UpdateCurrentControlsRequest becomes UpdateActiveControlsRequest, and the OpenAPI operation ids follow. In the layers module parse_group_id and find_group become parse_zone_id and find_zone, BroadcastMediaLayerGroupResponse becomes BroadcastMediaLayerZoneResponse, and in the zone module parse_if_match_groups_revision and attach_groups_revision_headers pick up the zones_revision name they now serve.

🎯 One consumer that would have failed silently

api/access_log.rs demotes high-volume layer reads from INFO to DEBUG so a Studio refresh loop cannot drown out real traffic, and it did so by matching the literal path segment "groups". A pure route rename would have left that matcher intact and quietly wrong: every layer read would have gone back to INFO with nothing failing. It now matches "zones".

🧪 The one domain the compiler could not check

Every other renamed field lives in hypercolor_types::api, so the daemon and its clients share one definition and a rename either compiles everywhere or nowhere. Displays is the exception: the daemon builds DisplayFaceResponse itself and the web UI, the SDK capture script, and the Python client each mirror it by hand. Renaming group to zone there compiled clean on both sides while silently desyncing the wire, which would have broken every face read and write in Studio and Display Preview, thrown inside just capture-faces, and raised a validation error in the Python client.

All four mirrors move in this PR, and a decode fence in the UI crate now deserializes the exact JSON the daemon's own tests assert it emits. The fence is the stand-in for the compiler check this domain lacks, and it retires when the displays contracts move into hypercolor_types::api.

💎 What moved in lockstep

The CLI, the TUI REST client, the web UI (both its API layer and the Studio pages that read the renamed fields), the vendored Python client, and the e2e harness all move here. The Python client under python/src/hypercolor/_generated/ was regenerated with scripts/generate_openapi_client.py, and its --check mode is clean against this tree.

The pinned fences were rewritten deliberately, which is what the lockstep doctrine asks of them. The REST matrix and its MATRIX.md companion now pin the new shapes, and the section that described these paths as legacy spellings kept beside canonical ones describes what they actually are: the only spellings, with a note on the body quirks that earn each row its place.

A new fence, renamed_routes_leave_nothing_behind, asserts that all six retired paths answer 404. Pinning the new routes only proves they exist; asserting the absence of the old ones is what distinguishes a deletion from an alias.

🔮 On /config/get and /config/set

These were already gone. Wave 4.3 shipped the registry-driven config resource routes (GET /config, GET/PUT/DELETE /config/keys/{key}, POST /config/reset, GET /config/schema), and a repo-wide search finds the old verb routes only in the spec prose that schedules their removal. No residue survived in any route, client, fixture, or doc. They are covered by the new 404 fence so the absence stays asserted rather than assumed.

🌊 What deliberately did not change

Persisted scene state. Scene::groups and Scene::groups_revision are written to disk in every saved scene. Renaming them would orphan user data without a schema bump and a migration, which is wave C1c's work. The daemon's API layer reads the persisted groups field and serves it under the zones name.

WebSocket event payloads. HypercolorEvent variants keep their group_id and groups_revision fields, and the render_group_changed event type string is unchanged. That surface belongs to the WS adoption worker's live lane, and this PR stays off api/ws/** and hypercolor-leptos-ext/** entirely.

Internal identifiers. hypercolor-core, the daemon's domain/ layer, and render_thread/ keep their render-group naming. Those are not wire names, and dragging them along would have buried a wire change in a thousand-line mechanical diff.

The Studio vocabulary page previously told doc authors that the zone rename was wire-safe. That stopped being true here, so it now states which surface spells the concept which way instead.

The effects domain served its live-control surface under a "current"
path segment while the sibling read routes already used "active". The
three writer routes now match: /effects/active/controls,
/effects/active/controls/{name}/binding, and /effects/active/reset.
The old paths are deleted outright rather than aliased, per the spec 76
lockstep doctrine.

Handler names, the request type, and the OpenAPI operation ids follow
the paths: update_current_controls becomes update_active_controls,
set_current_control_binding becomes set_active_control_binding, and
UpdateCurrentControlsRequest becomes UpdateActiveControlsRequest. Every
in-repo caller moves in this commit: the CLI, the TUI REST client, the
web UI, the Python client, the e2e harness, the pinned REST matrix and
its fixtures, and the docs that name the routes.

Zone CRUD already lived at /scenes/{id}/zones/{zone_id}, but the layer
stack hanging off the very same object was still reached through
/scenes/{id}/groups/{group_id}/layers. Both now share the /zones prefix
and the {zone_id} path parameter, and the old spelling is deleted rather
than aliased.

The broadcast-media payloads follow the paths: a fan-out target names
its zone_id, the response lists zones, and each entry carries zone_id.
BroadcastMediaLayerGroupResponse becomes BroadcastMediaLayerZoneResponse
to match.

The access log's quiet-path matcher keyed on the literal "groups"
segment to demote high-volume layer reads to DEBUG; it now matches
"zones", so those reads stay quiet instead of silently returning to INFO.

A new fence in the compat suite asserts the retired paths answer 404,
which is what distinguishes a deletion from an alias or a redirect. It
covers the effects rename from the previous commit and the already-gone
/config/get and /config/set as well.

Co-Authored-By: Nova (Claude Opus 5) <noreply@anthropic.com>
The zone REST contracts still spelled their payload fields in the older
render-group vocabulary: the active-scene response carried groups and
groups_revision, and all four zone responses carried groups_revision.
Both now read zones and zones_revision, matching the /zones routes that
serve them and the product's own word for the concept.

Every in-repo reader moves with them: the TUI's ActiveScene mirror and
its If-Match plumbing, the web UI's zone API and Studio pages, the
Python client's Scene and zone models, and the pinned matrix, fixtures,
and docs.

The rename stops at the wire. Scene::groups and Scene::groups_revision
are persisted on disk in every saved scene, so renaming them would
orphan user data without a schema bump and a migration; that is C1c's
work, not this wave's. The daemon's api layer therefore reads the
persisted groups field and serves it under the zones name.

Co-Authored-By: Nova (Claude Opus 5) <noreply@anthropic.com>
The effects payloads named their zone target in the render-group
vocabulary: apply, preset-apply, and reset requests took render_group,
and the active-effect response answered with render_group_id. All four
now read zone_id, which is what the value has always been.

The CLI, TUI, web UI, and Python client move with them, as do the
pinned matrix tests. Route-derived test names follow their routes, so
the suite no longer describes a legacy current path that no longer
exists.

The Studio vocabulary page described the zone rename as wire-safe,
which stopped being true here. It now says which surface spells the
concept which way: REST says zones throughout, while persisted scene
files and WebSocket event payloads keep the older spelling on purpose.

Co-Authored-By: Nova (Claude Opus 5) <noreply@anthropic.com>
The vendored OpenAPI client tracks the daemon's operation ids and
schemas, so the C1b renames land here as generated-module renames:
update_current_controls and set_current_control_binding become their
active spellings, UpdateCurrentControlsRequest follows, the layer
endpoints move to the /zones path, and the broadcast-media group
response becomes the zone response.

Regenerated with scripts/generate_openapi_client.py; --check is clean
against this tree.

Shorter identifiers let several wrapped expressions collapse back onto
one line.

Co-Authored-By: Nova (Claude Opus 5) <noreply@anthropic.com>
Running cargo inside the excluded hypercolor-ui crate rewrote its
separate lockfile and reformatted one pre-existing expression. Both
conditions also reproduce on an untouched main checkout, so neither
belongs in this PR.

Co-Authored-By: Nova (Claude Opus 5) <noreply@anthropic.com>
Two route tables kept prose that named a current effect beside the
renamed path, and the shorter path left their columns ragged. The
daemon-development skill and the REST spec now read active in both the
path and the description.

Co-Authored-By: Nova (Claude Opus 5) <noreply@anthropic.com>
Two doc comments still described the renamed fields in the old
vocabulary, one of them for a field the reader can no longer find.

Co-Authored-By: Nova (Claude Opus 5) <noreply@anthropic.com>
An adversarial pass over the rename found three defects that the
workspace check could not see, plus doc claims that contradicted the
code.

The CLI's scene reader still pulled "groups" off /scenes/active and
printed it as a Groups count. Nothing failed; it just reported zero
zones for every rig. It reads zones now and labels the row Zones.

Three control-surface mocks in the TUI tests were caught by a blanket
rename. ControlSurfaceDocument has its own groups field for driver
field grouping, unrelated to scene zones and carrying no serde default,
so renaming it in a fixture would have failed deserialization. Those
mocks are back to groups; only the scene-shaped one renames.

The new 404 fence asserted the wrong status for the flagship path.
PATCH /effects/current/controls falls through to the live
/effects/{id}/controls sibling with id bound to the literal current,
which fails UUID parsing and answers 400. That is still a deletion, and
the fence now pins the status each retired path actually returns, with
the collision explained where a future reader will hit it.

Two more zone-shaped REST payload fields join the flip: the display
face response and its MCP twin answer with zone rather than group, and
the media-admission 422 detail names zone_id and zone_name.

Spec 64 had been renamed too broadly. Its groups_revision references
describe the persisted Scene field, which this wave deliberately keeps,
so only its five wire-facing mentions and one route now change. Two
public docs stated the opposite of the code, one insisting the segment
was current rather than active and one attributing layer scoping to a
groups segment that no longer exists.

The generated client carries the daemon's doc comments verbatim, so the
later reword of two effects-contract comments left it a commit behind.

Merge Risk: 🟡 Moderate · up to 6a94c

The PR deletes old REST route spellings and renames wire fields, so exact contract alignment is required. At the current head, documentation still promises If-Match/ETag/412 behavior that the handler does not implement, and the cross-client contract check can miss JSON type changes; these could mislead callers or allow incompatible responses through CI, so merge should wait for alignment or explicit acceptance.

Renaming DisplayFaceResponse.group to .zone broke four consumers that
the workspace gates cannot see, because the displays domain is the one
surface in this wave with no shared hypercolor-types::api type behind
it. The daemon builds its own struct and each client mirrors it by
hand, so both sides compile happily while the wire desyncs.

The web UI's mirror declared a required group field, so every face read
and write failed to decode: Display Preview surfaced an error, Studio's
Screen composition rendered nothing, and a successful commit reported
failure. The SDK's capture-faces script reached through state.group and
would have thrown past its fetch-only try/catch, taking just
capture-faces down. The Python client's DisplayFaceAssignment required
group, and its test fixture still pinned the old shape.

A decode fence in the UI crate now deserializes the exact face JSON the
daemon's own api_tests assert it emits. It is the substitute for the
compiler check this domain lacks, and it retires when the displays
batch moves into hypercolor-types::api.

In `@crates/hypercolor-daemon/tests/fixtures/rest_v1/MATRIX.md`:
- Line 206: Update the POST /api/v1/effects/active/reset entry in MATRIX.md to
document both supported request forms: an empty body for resetting all active
effects and a body containing zone_id for resetting a named zone, while
preserving the existing 200 enveloped response description.

In `@docs/content/studio/architecture.md`:
- Line 170: Update the architecture documentation sentence describing Studio
mutation concurrency to scope the guarantee to structural and explicitly
versioned guarded mutations, rather than claiming every mutation carries a
precondition. Ensure it reflects that some zone patches and bulk layer targets
may be unconditional.

In `@docs/design/05-api-design.md`:
- Around line 2607-2608: Update the GET /effects/active endpoint summary from
“Current effect” to “Active effect,” preserving the existing endpoint and
method.

In `@docs/specs/10-rest-websocket-api.md`:
- Line 1058: Update the two opening Markdown code fences at the referenced HTTP
examples to include an appropriate language identifier, such as http, resolving
MD040 while leaving the example contents unchanged.

Apply the same fix in `@docs/specs/60-user-media-and-layer-stack.md` at line 1361:
Untagged HTTP request fence with the same remediation.

In `@docs/specs/31-effect-developer-experience.md`:
- Line 1538: Update the curl request examples at the affected control endpoints
to send a flat control_id-to-value JSON object instead of wrapping values inside
a controls property, matching the REST/WebSocket API contract.

In `@docs/specs/37-cli-completeness-and-styling.md`:
- Around line 383-384: Add POST /effects/active/reset to the canonical REST API
references in the REST API specification and API design documentation, alongside
the existing effects control routes. Keep the documented method and path
consistent with the daemon endpoint and the CLI mapping.

In `@docs/specs/46-interactive-viewport-designer.md`:
- Line 808: Align the documented contract for PATCH
/api/v1/effects/active/controls with its implementation: remove
If-Match/ETag/412 expectations and describe expected_version=None with stale
refusals mapped to 409 Conflict. Apply the documentation correction at
docs/specs/46-interactive-viewport-designer.md:808,
docs/specs/60-user-media-and-layer-stack.md:1146, 1204, and 1356-1357, and
docs/specs/64-multi-zone-scenes.md:741-746; no route implementation change is
required.

In `@python/src/hypercolor/client.py`:
- Around line 402-414: Add regression tests for the zone_id handling in
apply_effect, reset_controls, and apply_preset. Pass a zone_id to each method
and assert the request body contains exactly {"zone_id": ...} alongside any
required fields, adding coverage for reset_controls and extending the existing
apply_effect and apply_preset tests.

In `@python/src/hypercolor/sync_client.py`:
- Around line 170-178: Extend the synchronous-client tests around apply_effect
and reset_controls to invoke both methods with a zone_id, asserting their exact
request bodies include the forwarded zone_id and omit render_group. Follow the
existing apply_effect_preset test conventions in test_sync_client.py.

In `@python/tests/test_scenes_zones.py`:
- Line 319: Update the zone-update test to retain the result returned by
update_zone and assert that its zones_revision value is 13, matching the

Document the named-zone reset request.

The table says this endpoint accepts an empty body. crates/hypercolor-daemon/tests/api_tests.rs lines 8374-8379 show that it also accepts { "zone_id": ... } to reset a named zone. Document both request forms. Otherwise, clients using this matrix cannot discover the named-zone reset operation.

Proposed fix
-| POST | `/api/v1/effects/active/reset` | Empty | `200`, enveloped | |
+| POST | `/api/v1/effects/active/reset` | Empty or `{zone_id: ...}` | `200`, enveloped | |

Update the POST /api/v1/effects/active/reset entry in MATRIX.md to document both
supported request forms: an empty body for resetting all active effects and a
body containing zone_id for resetting a named zone, while preserving the
existing 200 enveloped response description.

## Optimistic concurrency

Every Studio mutation is optimistic and guarded. Two preconditions cover the whole surface: zone and scene mutations carry the active scene's `groups_revision`, and layer mutations carry `layers_version`. Both ride as the `If-Match` header. A stale write is never silently lost. The daemon reports a `Stale` outcome, the client reloads, and the user retries.

Limit the concurrency guarantee to guarded mutations.

Line 170 states that every Studio mutation carries a concurrency precondition. The zone API matrix states that name, color, brightness, and enabled-only patches skip zones_revision. Bulk layer targets can also use an unconditional version. Change this sentence to describe structural and explicitly versioned mutations only.

Use active terminology in the endpoint summary.

Line 2607 still describes /effects/active as Current effect. Rename the description to Active effect so the quick reference does not reintroduce the removed API terminology.

Align the active-controls concurrency contract with the implementation. PATCH /api/v1/effects/active/controls ignores If-Match, passes expected_version: None, emits no mutation ETag, and maps its stale-refusal branch to 409 Conflict. The If-Match/ETag/412 Precondition Failed contract exists on PATCH /api/v1/effects/{effect_id}/controls, not the legacy active route. Update the cited specifications or implement the contract on the legacy route.

Add regression tests for all zone_id parameters. Cover apply_effect, reset_controls, and apply_preset with zone_id and assert the exact {"zone_id": ...} request body. reset_controls has no test, and existing apply_effect and apply_preset tests omit zone_id.

Add synchronous-client tests for apply_effect and reset_controls.

python/tests/test_sync_client.py covers apply_effect_preset, but it does not invoke the other two methods. Add cases that pass zone_id and assert the exact request bodies. This must confirm zone_id forwarding and the absence of render_group.

Assert zones_revision for zone updates.

The fixture now supplies zones_revision: 13, but the test discards the update_zone result. This leaves the renamed PATCH response field unverified, unlike the other zone mutation tests. Store the result and assert its revision.

As per coding guidelines: Tests are mandatory: every public type/function needs coverage in tests/.

Proposed test fix
-    await client.update_zone(SCENE_ID, ZONE_ID, brightness=0.5, color=None, if_match=12)
+    result = await client.update_zone(
+        SCENE_ID,
+        ZONE_ID,
+        brightness=0.5,
+        color=None,
+        if_match=12,
+    )
 
     body = json.loads(route.calls[0].request.content)
     assert body == {"brightness": 0.5, "color": None}
     assert "description" not in body
+    assert result.zones_revision == 13

The fence's own comment overclaimed. It said the test pins the exact
JSON the daemon emits so the mirror cannot drift silently, which reads
as protection against any drift. It is narrower than that in two ways
worth writing down, because wave 3.1 inherits this residue.

The literal is a subset carrying the fields this crate reads, not all
seventeen a Zone serializes. And because the UI crate has no dependency
on the daemon, the test cannot observe the real serializer: it catches a
rename on the client side, but a daemon-side rename that updates the
daemon's own pins would let the mirror and the literal drift together
with both suites green. Closing that needs the shared type, not a bigger
fixture.

The MCP set_display_face tool and its published reference still
described control overrides as landing on the display face group, three
lines from the payload key that now says zone. The vocabulary page bans
group as prose for a zone, and these strings are what an agent reads.

The UI's face decode fence used a hand-copied literal, so a
daemon-side rename that updated the daemon's own pins would drift
both sides together silently. The daemon now pins its live
serializer's key paths against tests/fixtures/rest_v1/
display_face_shape.json, and the UI decode test reads the same file:
a rename must update the fixture, and the updated fixture must still
decode into the UI mirror. The residue narrows to value semantics
until the displays domain moves into hypercolor_types::api.

Also pin the renamed zone_id/zone_name keys in the media-admission
422 layer details, which the cap test previously asserted only by
counts and prose.

Compare JSON types as well as JSON key paths.

Lines 16444 through 16452 compare only key paths. This test passes if the daemon changes a scalar type, or changes an empty array to an empty object. The static UI fixture still decodes, so the cross-client REST contract can drift without a failing test.

Record each node’s JSON type with its path. Record array type even when the array is empty.

-fn collect_key_paths(value: &serde_json::Value, prefix: &str, out: &mut Vec<String>) {
