Summary

  • Replace ad hoc shelf-based content placement with principled spatial formalism derived from AoA stella octangula geometry
  • 30 anchor points (8 HIGH cube-vertices, 10 MEDIUM octahedron/child, 12 LOW trisection) with mandala zone discipline (Utama/Madya/Nista)
  • Camera: 75° FOV, energy-modulated orbit, atmospheric perspective (depth desaturation + light falloff)
  • Tensegrity breathing: opacity-driven radial push/pull in spatial drift
  • Triangular grid on floor/ceiling, volumetric beams retargeted to dual tetrahedron vertices
  • YouTube JPEG direct-load for insphere texture; DoF shader written but disabled (NVIDIA 595.71 SPIR-V crash)
  • Migrated work from 3 prior worktrees (reverie-spherical, aoa-sphere, aoa-naming)

Research basis

8 parallel research agents produced converging evidence across:

  • Enactivist phenomenology (Varela, Merleau-Ponty, Gibson)
  • Functionally symbolic structures (stella octangula, mandala cosmograms, tensegrity)
  • Empirical livestream spatial design (eye-tracking, VTuber stages, sustained viewing)
  • Hapax constitutional constraints (nebulous scrim, anti-visualizer, anti-parasocial)

6 REQ specs written: REQ-20260522-scroom-{tetrahedral-spatial-formalism, depth-of-field-focus-pull, enactive-camera-system, tensegrity-layout-breathing, tetrahedral-grid-projection, deliberate-occlusion-depth-revelation}

Test plan

  • 59 scene tests pass (anchor zone invariants, entropy classification, camera bounds)
  • Binary builds clean (1 dead_code warning)
  • Deployed to hapax-imagination, service stable
  • Visual verification: content distributed at tetrahedral anchors, triangular floor grid visible, atmospheric perspective working
  • CI checks

Review Change Stack

cc-task: 20260522-scroom-tetrahedral-spatial-formalism

…yout

Replace ad hoc shelf-based content placement with a spatial formalism
derived from the AoA's stella octangula geometry.

Core changes:
- 30 anchor points (8 cube-vertices HIGH, 10 octahedron/child MEDIUM,
  12 trisection LOW) computed from tetrahedral dual geometry
- Three mandala zones (Utama r<2.5, Madya 2.5-4.5, Nista >4.5)
  enforce spatial discipline around AoA centroid
- Content sources classified by entropy (HIGH/MEDIUM/LOW) and placed
  at geometrically principled positions
- Camera FOV widened from 60 to 75 degrees for stronger peripheral depth
- Energy-modulated orbital drift (radius 1.25-2.0, period 72-90s)
- Atmospheric perspective: depth-dependent desaturation and light falloff
- Tensegrity breathing: opacity-driven radial push/pull in spatial drift
- Triangular grid on floor/ceiling (tetrahedral tiling at AoA edge spacing)
- Diagonal grid lines on walls
- Volumetric beams retargeted to dual tetrahedron vertex positions
- YouTube JPEG loaded directly from compositor SHM for insphere texture
- DoF shader written but disabled (NVIDIA 595.71 SPIR-V driver crash)

Migrated work from 3 worktrees:
- alpha/reverie-spherical-surface (sphere + YouTube + shaders)
- alpha/aoa-sphere-warmth-signal (insphere + warmth)
- alpha/aoa-naming-migration-completion (AoA rename + heatmap + tests)

6 REQ specs written for the complete formalism (REQ-20260522-scroom-*).

…t gaps

Fixes from 4-agent parallel audit:

1. GPU texture leak: upload_yt_jpeg_if_fresh now reuses a persistent
   texture instead of creating a new one every 3 frames. Only recreates
   when YouTube frame dimensions change.

2. Sphere warmth atomic corruption: split single AtomicU32 into separate
   FRAME counter and CACHED warmth value. Previously the fetch_add frame
   counter and the stored warmth bits corrupted each other.

3. Cross-role anchor fallback: when same-role anchors are exhausted,
   sources fall back to unused anchors of other roles instead of being
   silently dropped. Prevents invisible content in 40+ source scenes.

4. Four new unit tests:
   - scene_anchors_returns_30_points_with_correct_role_counts
   - classify_source_entropy_routes_correctly
   - anchor_exhaustion_drops_excess_sources_gracefully
   - orbital_drift_with_max_energy_stays_bounded

5. Restored overflow test assertion strength (unwrap instead of if-let).

6. Fixed misleading dof=enabled log message to dof=disabled.

P1 Badge Re-register Sierpinski class name alias

Registering only AoaCairoSource here removes the SierpinskiCairoSource key that existing layouts still reference (for example config/compositor-layouts/default.json source sierpinski), so SourceRegistry.construct_backend will raise a KeyError when it resolves params.class_name during compositor startup. This makes the canonical layout fail to instantiate unless every layout is migrated in the same change; keep a compatibility alias (register both names) until the JSON corpus is updated.

P1 Badge Separate warmth cache from frame counter

read_sphere_warmth() uses one AtomicU32 both as a frame counter (fetch_add) and as cached float bits (store(warmth.to_bits())), so after the first cache write every subsequent fetch_add mutates the float bit pattern instead of counting frames. In practice the function returns drifting/garbage warmth values on most frames and can inject unstable color modulation into the sphere; use distinct atomics (or local statics) for frame cadence and cached warmth.

P2 Badge Preserve unique pane for fire material

Depth-2 pane indexing collapses fire onto the same bucket as void because MATERIAL_INDEX maps fire to 4 but _pane_ordinal_depth2 uses (material % 4). Any impingement/recruitment tagged fire will overwrite the void pane instead of its own material lane, so the AoA heatmap can no longer represent those two materials distinctly.

…rchy

Narrow the size ratio between HIGH/MEDIUM/LOW content quads from ~8:1
to ~3:1 area ratio. LOW sources (tickers, atmospheric) were illegibly
small at 0.20 height; raised to 0.28. HIGH (cameras) reduced from 0.50
to 0.44.

Viewer experience: content sources should be distinguishable by size
(hierarchy) but all must remain legible at livestream resolution.

Cursor invalidation on file truncation or rotation.

If the JSONL file is truncated or rotated (replaced with a new file), the stored cursor position may exceed the new file's length. While f.seek() to a position beyond EOF won't error, subsequent reads will return nothing until the file grows past the old cursor—missing all events written to the rotated file.

Consider checking if the file size is smaller than the cursor (indicating rotation) and resetting to 0:

Optimize: avoid redundant texture sample.

Line 153 samples tex again, but the original color was already sampled at line 95 and stored in color. Sampling the same texture twice per fragment is inefficient.

⚡ Proposed fix: reuse the original sample

Store the original color before modifications:

 fn main_1() {
     var color: vec4<f32>;
+    var original_color: vec3<f32>;
     var gray: f32;
     var sep: vec3<f32>;

+    original_color = _e15.xyz;
     source_luma = dot(color.xyz, vec3<f32>(0.299f, 0.587f, 0.114f));

Then use original_color instead of re-sampling:

     graded = mix(_e117.xyz, _e116, vec3(surface_presence));
     // Preserve entity color identity: blend graded result back toward
     // original so entity hue always shows through the color grade.
-    let original = textureSample(tex, tex_sampler, v_texcoord_1).xyz;
     let entity_preserve = 0.90;
-    graded = mix(graded, original, vec3(entity_preserve * surface_presence));
+    graded = mix(graded, original_color, vec3(entity_preserve * surface_presence));

276-311: 💤 Low value

Computed sphere_depth is unused; hardcoded 0.999 returned instead.

Line 278 computes perspective-correct depth via hit_clip.z / hit_clip.w, but Line 311 returns a hardcoded 0.999. While this may be intentional for the "panes occlude sphere" ordering, the computation is then wasted. If hardcoded depth is desired, consider removing the unused computation or documenting the intent.

In `@agents/studio_compositor/aoa_heatmap.py`:
- Around line 130-133: The function _pane_ordinal_depth2 currently compresses
material indices with (material % 4), which maps MATERIAL_INDEX entry 4 (fire)
to the same slot as 0 (void); update the slot calculation in
_pane_ordinal_depth2 to use a stride of 5 (e.g., replace material % 4 with
material % 5 or change the family_slot*4 stride to family_slot*5) so each
material index 0–4 maps to a distinct pane; ensure any other constants relying
on a 4-wide packing are adjusted or documented if you choose to keep
compression.

In `@agents/studio_compositor/aoa_loader.py`:
- Around line 186-187: stop() currently only flips _running and fails to stop
directors started in _start_director(); update stop() to call stop/cleanup on
self._director, self._twitch_director, and self._structural_director (if they
exist) and then clear them (or join/wait if those directors expose join/await
methods) to ensure background threads exit. Also initialize those attributes to
None in __init__ (or ensure they always exist) and replace any hasattr checks
with explicit "is not None" checks when guarding calls to
_director/_twitch_director/_structural_director; reference the
_start_director(), stop(), _director, _twitch_director, and _structural_director
symbols when making the changes.
- Around line 91-107: The constructor __init__ neglects to declare the instance
attributes that _start_director() sets ( _director, _twitch_director,
_structural_director ), which can lead to AttributeError if those are accessed
before startup or if startup fails; declare and initialize these attributes in
__init__ (e.g., self._director = None, self._twitch_director = None,
self._structural_director = None) with appropriate typing hints or forward refs
(use TYPE_CHECKING imports if needed) so callers and linters know the attributes
exist even before _start_director() runs.

In `@agents/studio_compositor/aoa_renderer.py`:
- Around line 381-394: The current block can leave orphaned temp files if
os.replace raises OSError because tmp_path is never cleaned up; modify the
try/except so tmp_path is tracked (e.g., initialize tmp_path = None before the
with), and in the exception handler (or a finally) attempt to
os.unlink(tmp_path) if tmp_path is set and the file exists; ensure you only call
os.unlink after ensuring tmp_path is not None and catch/remove any OSError from
the unlink to avoid masking the original error. Use the existing
VIDEO_ATTENTION_PATH code path and tmp_path (from the NamedTemporaryFile) to
locate and remove the orphaned .video-attention.*.tmp file.

In `@hapax-logos/crates/hapax-visual/src/scene_renderer.rs`:
- Around line 347-361: The function read_sphere_warmth incorrectly uses a single
static AtomicU32 (LAST) for both frame counting and caching, corrupting the
cached float bits; split responsibilities by introducing two statics (e.g.,
FRAME_COUNTER: AtomicU32 = AtomicU32::new(0) for fetch_add increments and
LAST_WARMTH: AtomicU32 = AtomicU32::new(0.5f32.to_bits()) for cached warmth).
Change fetch_add and modulus checks to use FRAME_COUNTER, use
LAST_WARMTH.load(Ordering::Relaxed) when returning cached values, and store
warmth bits into LAST_WARMTH.store(warmth.to_bits(), Ordering::Relaxed) after
reading from the file. Ensure initial LAST_WARMTH is set to a sane default
(0.5f32.to_bits()) and keep Ordering::Relaxed for both operations.

In `@hapax-logos/src-imagination/src/headless.rs`:
- Around line 159-160: The field scene_shm (ShmOutput) is allocated but never
used to publish scene frames; update the render pipeline in render_frame() to
copy the rendered texture into the SHM buffer and call scene_shm.write_frame so
the direct scene output path works. Specifically, after the scene is rendered
(use scene.output_texture() or the texture returned by Scene::render), map or
blit the texture into the scene_shm pixel buffer using the same format/stride
used by ShmOutput, then call scene_shm.write_frame() (or the equivalent method
on ShmOutput) with the populated buffer and proper timestamp/frame metadata;
ensure this logic mirrors how intermediate/primary outputs are handled and guard
it behind the existing scene_shm presence checks so the branch only runs when
scene_shm is enabled.

In `@tests/studio_compositor/test_aoa_no_yt_extraction.py`:
- Around line 43-45: The AST import guard only checks alias.name which misses
"from subprocess import run"; update the check in the loop over node (used for
ast.Import and ast.ImportFrom) to also inspect node.module when node is an
ast.ImportFrom and assert node.module != "subprocess" (or fail with the same
message referencing path) so that both plain imports and from-imports from the
subprocess module are caught; refer to the existing symbols node, ast.Import,
ast.ImportFrom, alias.name, names, node.module and path to locate and modify the
assertion logic.

In `@tests/studio_compositor/test_geal_source.py`:
- Around line 360-365: Update the stale inline comment that mentions
"Sierpinski's geometry cache" to accurately reference the AoA geometry source
used here: change the comment to state that the centre invariant is resolved via
AoaCairoSource's geometry cache; locate the comment above the import/usage of
AoaCairoSource and geometry_cache and replace the wording so it explicitly
mentions AoaCairoSource().geometry_cache (target_depth=2, canvas_w=1280,
canvas_h=720) instead of Sierpinski's geometry cache.

In `@tests/studio_compositor/test_video_attention.py`:
- Around line 25-28: This test file is failing Ruff formatting checks; run the
formatter (e.g., ruff format) on the test file and fix import/spacing issues so
imports like VIDEO_ATTENTION_PATH and AoaCairoSource (and the other import
groups referenced) follow project style; ensure imports are grouped/ordered and
whitespace is normalized across the file, then re-run ruff format --check to
verify the file passes CI.

In `@tests/test_audio_visual_correlation.py`:
- Around line 21-27: The file's import blocks aren't formatted to Ruff's
standards; run the formatter (ruff format) on the test file and fix import
formatting so multi-line imports like AUDIO_LINE_WIDTH_BASE_PX,
AUDIO_LINE_WIDTH_SCALE_PX, SIERPINSKI_AUDIO_ATTACK_ALPHA,
SIERPINSKI_AUDIO_BURST_CLAMP, and AoaCairoSource are arranged and wrapped per
Ruff/PEP8 conventions and applied consistently for the other import groups
referenced in the review; ensure the import lines are reorganized/line-broken
uniformly across the file so ruff format --check passes.

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Material "fire" collides with "void" due to material % 4.

MATERIAL_INDEX defines 5 materials (indices 0–4), but material % 4 maps index 4 (fire) to 0, causing fire events to update the same pane as void events. This likely should be material % 5 or the slot stride should be 5 instead of 4.

Proposed fix
 def _pane_ordinal_depth2(domain: int, family_slot: int, material: int) -> int:
     base = 20
-    slot = domain * 16 + family_slot * 4 + (material % 4)
+    slot = domain * 20 + family_slot * 5 + (material % 5)
     return base + (slot % 64)

Note: This changes the slot stride and may require adjusting other constants if pane distribution matters. Alternatively, if the compression is intentional, document that fire maps to the void slot.

scene_shm is allocated but never used to publish scene frames.

Lines 159/212/239 add the direct scene SHM path, but render_frame() never copies scene.output_texture() into scene_shm or calls scene_shm.write_frame. So the “direct scene output” path is currently non-functional.

update the render pipeline in render_frame() to copy the rendered texture into
the SHM buffer and call scene_shm.write_frame so the direct scene output path
works. Specifically, after the scene is rendered (use scene.output_texture() or
the texture returned by Scene::render), map or blit the texture into the
scene_shm pixel buffer using the same format/stride used by ShmOutput, then call
scene_shm.write_frame() (or the equivalent method on ShmOutput) with the
populated buffer and proper timestamp/frame metadata; ensure this logic mirrors
how intermediate/primary outputs are handled and guard it behind the existing
scene_shm presence checks so the branch only runs when scene_shm is enabled.

P2 Badge Reset cursor when log file shrinks

_read_new_impingements stores a byte offset and seeks to it unconditionally, but it never handles file truncation/recreation. When /dev/shm/hapax-dmn/impingements.jsonl (or similarly the recruitment log) is rotated or rewritten, the saved cursor can point past EOF, so subsequent reads return no lines and the heatmap silently stops ingesting new events until the file grows beyond the stale offset. Add a size/inode check and reset the cursor to 0 when the file has been replaced or shrunk.

P2 Badge Use ray-marched depth for insphere fragments

The shader computes sphere_depth from the ray-sphere hit point but returns a hardcoded fragment depth of 0.999, so every insphere pixel is written at nearly the far plane regardless of actual geometry. This breaks depth-correct occlusion as the camera moves (the sphere cannot properly interleave with other 3D content) and defeats the purpose of the hit-point projection done just above; return the computed depth instead of a constant.

Useful? React with 👍 / 👎.

Anchors with near-vertical direction from AoA centroid (vertical_ratio
> 0.7) now get a lateral spread applied before distance normalization.
This prevents content from clustering directly below the AoA and
intersecting the floor plane.

Previously anchor 6 (cube-vertex B-dual, directly below centroid) would
be placed at y=-3.0 after scaling, well below the floor at y=-2.0. Now
it gets pushed sideways, staying at the correct radial distance while
keeping a visible position above floor level.

…am res

Replace 30-point tetrahedral scatter with two-band concentric arc layout
designed for the 2D projection the viewer actually sees.

- Band 1 (inner, r=3.8): HIGH-entropy sources (cameras, IR, CBIP) at
  height 0.56, full opacity. Spread across full circle.
- Band 2 (outer, r=4.6): MEDIUM/LOW sources (wards, tickers) at height
  0.44, 0.72 opacity. Offset rotation for visual separation.

Key insight from operator: the tetrahedral scatter was mathematically
principled but visually illegible — "postage stamps scattered randomly."
Content must be large enough to read at 1080p and arranged so the
projection makes spatial sense to the viewer.

The tetrahedral anchor system remains as infrastructure (scene_anchors(),
classify_source_entropy(), mandala zones) for future use by the
tensegrity breathing system. The arc layout is the immediate fix for
viewer legibility.

Line 116 and Line 117 add explicit floor/ceiling limits, but scale_anchor_outward() never applies them.

…munication above, grounding below

Replace arc scatter with four-region semantic layout that communicates
Hapax's functional architecture to the viewer:

- LEFT: cameras + IR (perception — what Hapax sees). 2-column grid.
- RIGHT: wards + data (cognition — what Hapax thinks). 2-column grid.
- ABOVE: tickers, chat, programme context (communication — Hapax speaking).
- BELOW: provenance, precedent, evidence (grounding — epistemic floor).
- CENTER: AoA tetrix (Hapax's self-representation).

The spatial organization is now legible at 1080p and communicates
function, not arbitrary geometry. Camera feeds are large enough to
identify. Ward text is readable. The layout tells the viewer: this
system has perception, cognition, communication, and grounding.

Nitpick comments:
In `@hapax-logos/crates/hapax-visual/src/scene.rs`:
- Around line 2089-2090: The finiteness-only assertion around ir.position (the
check ir.position.is_finite()) is too weak — add a minimum-separation invariant
to prevent nodes collapsing onto each other/AoA: compute the Euclidean distance
between ir.position and the relevant anchor/neighbor position(s) (use the same
distance helper used in nearby tests or Vec2::distance) and assert it exceeds a
named constant like MIN_IR_SEPARATION (pick a sensible value from nearby tests
or define it close by). Replace the plain is_finite() assertion with a combined
check (is_finite() && distance > MIN_IR_SEPARATION) and update the error message
to mention the minimum separation; apply the same change to the other occurrence
that mirrors this check (the second ir.position assertion).

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Grounding classifier is shadowed by the ticker classifier.

IDs like precedent_ticker/chronicle_ticker match the communication branch first, so they never reach grounding classification even when they carry grounding semantics.

In `@hapax-logos/crates/hapax-visual/src/scene.rs` around lines 1079 - 1085, The
communication branch currently checks id.contains("ticker") etc. before the
grounding-related keywords, causing IDs like "precedent_ticker" to be captured
by communication; fix by ensuring grounding-related matches (e.g.,
id.contains("provenance") || id.contains("precedent") ||
id.contains("chronicle") || id.contains("pressure")) are evaluated before the
communication branch or by adding an exclusion to the communication condition to
skip when grounding keywords are present; update the logic around the same id
checks that push into communication (and the counterpart grounding push) so
grounding ids are classified into the grounding collection rather than being
shadowed by the ticker/chat branch.

Grounding sources at y=-1.60 were projecting onto the translucent floor
grid (y=-2.0), creating a false mirroring effect. Raised to y=-1.15
and pushed z forward so they read as content above the floor, not
embedded in it.

Grounding sources were placed behind the AoA (z=-2.76) where the
translucent floor grid draws over them from the camera's perspective,
creating a mirroring artifact regardless of y position. Moved to z=-1.26
(in front of AoA, between camera and tetrix) so the floor grid is
behind them, not in front.

Merge communication, cognition, and grounding into a single right-side
column at the same depth as cameras (cam_z). Eliminates the floor-grid
overlay artifact that persisted through two fix attempts.

The four-region model (perception/cognition/communication/grounding)
was creating three different depth bands which each had floor interaction
problems. The bilateral model (cameras left, everything else right,
AoA center) is simpler, more legible, and artifact-free.

… room

Spread content across the full room volume instead of cramming into
narrow columns near the AoA:

- LEFT WALL (x=-4.5 to -5.9): cameras in 2-col grid, y range ±1.2
- RIGHT WALL (x=4.0 to 6.4): wards in 3-col grid, y range ±1.2
- TOP (y=1.6-1.95): communication, spread horizontally near ceiling
- FRONT-BOTTOM (y=-1.2, z forward): grounding, above floor plane

Room is 30 units wide — use it. No more floor-plane clipping because
nothing extends below y=-1.5. The semantic organization is maintained
(perception left, cognition right, communication above, grounding
front) while using the spatial depth the room provides.

Replace the ray-marched cylinder (which caused severe perspective
warping, invisible walls, and backward-ray artifacts) with 8 flat
octagonal wall panels + 4 level platforms.

Architecture:
- 8 wall panels (45° each, radius 6, full tower height)
- 4 level platforms at y=1, 4, 7, 10 (the cornices become floors)
- Ground floor (quad 0) and ceiling retained
- Light marker + 4 volumetric beams renumbered to quads 13-17
- AoA insphere at quad 18

Camera:
- Gentle pendulum (up then down, no snap)
- Rises from y=1 to y=8, descends back
- 120-150s period, one revolution
- Targets always look at AoA height (y=5.5)

Content fixes:
- rot_y corrected: theta+PI (was atan2(cos,-sin), 90° wrong)
- All content now faces inward toward the tower axis

The flat panels are proven technology (floor/ceiling already work
perfectly). No ray-marching, no backward rays, no billboard coverage
gaps. The viewer sees actual wall surfaces, not thin lines in a void.

Level platforms are now spiral ramp segments — wide tilted quads that
hug the outer wall (r=2.5 to 5.7), leaving the central void open.

Each segment covers 90° of arc and rises 3 units (one level height).
4 segments create a continuous ascending spiral ramp from y=-2 to y=10.
The ramp is the visible path the camera follows through the tower.

The open center void means you can look down/up through the tower
shaft at any point, seeing the AoA and other levels.

Ramp segments now follow the octagonal wall geometry — each plank
aligns with a pair of wall panels (90° arc), outer edge flush with
the wall. Inner edge at r=2.0 leaves the central void open.

Each plank rises 1.5 units across its width, creating a gentle slope.
4 planks cover the tower's vertical extent.

Each shelf is a 3.5×3.0 rectangle positioned tangent to the wall at
y=0, 3, 6, 9. Outer edge flush with wall (r=5.5), inner edge at r=2.5
leaving central void open. Slight 0.5-unit tilt for ramp feel.

Rotated 90° per shelf (0°, 90°, 180°, 270°) creating a spiral
staircase of wide flat platforms ascending the tower.
