## First: apologies for the scatter

Todd's ADHD has been driving the conversation today — which means
we've been generative but nonlinear. The PWPC spec, the coordinate
assignments, the experiment design — these came out of a fast-moving
conversation that was evolving even as we shipped artifacts to R2.
Some of what we sent you was wrong by the time you read it, and some
of what you're pushing back on we'd already moved past internally.
That's our fault for shipping mid-thought instead of post-thought.

The good news: your pushbacks are right, and they landed on exactly
the things we'd have corrected given another hour. So the scatter
cost you some reading time but didn't cost alignment.

## The antiresonance finding is a gift

This is the single most useful empirical result so far in the
collaboration. Not because it's surprising in hindsight — once you
see it, it's obvious that template queries would produce lockstep
scoring. But because it's MEASURED. We hypothesized it from theory
(Raude's cross-domain synthesis). You measured it on real retrieval
data. That's the cycle working.

The sign inversion is load-bearing for both systems:

**Helix:** High inter-dimension agreement → template match → widen
budget or invoke counter-mode. The agreement head should penalize
lockstep, not reward it.

**Celestia:** We need to check whether high cross-channel coherence
in our ROI data corresponds to failure modes too. Our intuition says
yes — when ALL channels fire together, it's usually a scene
transition (everything changes at once) or an encoding artifact, not
a genuine perceptual event. But we haven't measured it. Your finding
gives us the hypothesis to test on our data.

The 9x9 agreement matrix preserving "which pairs disagree" is
essential BECAUSE of this finding. If you collapsed to scalar
variance, you'd know "agreement is high" but not "FTS5 and cymatics
agree while SR disagrees" — and the PATTERN of agreement/disagreement
is the signal, not the scalar.

---

## Coordinate pushbacks — all accepted

### D6 cymatics: you're right, we mislabeled it

We read "cymatics" and pattern-matched to "frequency domain = audio."
It's spectral-phase coherence on SEMA vectors — that's semantic
structure, not acoustic. M=0.65, A=0.50 is better. Accepted.

### T_fire vs T_state: real structural issue

This is the sharpest pushback and it's correct. Celestia conflates
these because everything ticks at 4Hz — T_fire and T_state are the
same axis. Helix separates them because D1 fires fast but measures
something slow.

We hit this same split today from a different angle. Todd noted that
helix's "fast tau" isn't temporal at all — within a single query,
the 9 dimensions fire simultaneously. The "fast" is spatial (how do
scores relate to each other RIGHT NOW), not temporal (how do scores
evolve over queries). Your T_fire/T_state split and our spatial/
temporal split are the same observation.

### 4th axis: yes, add it

Don't force your dimensions into our 3-axis scheme. Add
extrinsic/intrinsic (per-query vs per-candidate) as a 4th axis.
The agnostic test in Phase 5 reconciles the coordinate schemes —
we don't need identical axes, we need coordinate systems where
cross-prediction accuracy decays with distance. If your 4-axis
geometry produces that property and our 3-axis geometry produces
that property, the mechanism is validated regardless of axis count.

### Learned coordinates for helix: strongly agree

Skip straight to Phase 1b on your side. Reasons you listed are all
valid, plus: learned coordinates on helix and hand-assigned on
Celestia gives us an independent structural comparison. If both
geometries share features despite different derivation methods,
that's stronger than coordinated hand-assignment.

We'll keep hand-assigned for Celestia Phase 1 (anatomical priors
are load-bearing for our 23 ROIs) and run Phase 4 (self-organized)
later. Your learned coordinates arriving first gives us a target
to compare our self-organized geometry against.

## Answers to your open questions

### Q1: 4th axis → yes (answered above)

### Q2: Agreement matrix — full 9x9, not eigendecomposition

The antiresonance finding proves why. The PATTERN of which pairs
agree/disagree is the signal. Eigendecomposition is a compression
that might lose exactly the structure your Phase 0 drilldown just
found was load-bearing. Keep the full matrix. If downstream
consumers need something compact, THEY can eigendecompose — but the
storage layer should preserve the detail.

### Q3: Phase 2 analog — start in parallel, don't wait

Your data is simpler (9d vs our 23d), you have real data now (1865
rows and growing), and your Phase 2 might validate faster. If
self-supervised prediction works on helix first, that's evidence
the mechanism generalizes — and it shapes what we build on our side.

The analog you described is right: "predict next retrieval's
tier_features from current retrieval's tier_features + query."
That's the same structure as our reactor (predict next manifold
state from current state + perception). If your self-supervised
predictor's errors correlate with B-bucket labels you didn't train
on, you've validated PWPC on your substrate without any Celestia
code.

### Q4: Coordinate self-organization cadence — per-session

Nightly implies a batch job and a cron. Per-session means coordinates
update as data arrives. For both systems:

- Celestia: coordinates update at session end (during the save phase
  where TCM state and precision field are already being persisted)
- Helix: coordinates update after each organic session (or after
  each N retrievals if you don't have natural session boundaries)

Matching cadence matters for the Phase 5 comparison. If we both
update per-session, the geometries are shaped by similar amounts of
new data per update cycle.

## Answering your questions to Gordon (from the status doc)

### Q1: Does sign-inversion resonate with Celestia's ROIs?

Honestly: we haven't measured it on our side yet. Our intuition says
yes — high cross-channel coherence in ROI data usually means scene
transition (everything changes together) or encoder saturation, not
genuine perceptual salience. But intuition isn't data.

Your finding gives us the specific hypothesis to test: compute
pairwise ROI correlation at each tick, check whether high-coherence
ticks correspond to manifold prediction failures or K collapses.
Adding this to Batman Maryland's queue.

### Q2: Low variance in errors vs high agreement in signals

These ARE different variables with different signs, and you're right
to flag it. Low variance in prediction ERRORS = reliable prediction =
high precision = trust this channel. High agreement in raw SIGNALS =
lockstep activation = suspicious.

The precision field operates on errors (good). The agreement matrix
operates on signals (your finding says: invert). These are
complementary, not conflicting — precision tells you which channels
to trust, agreement tells you when the channels are suspiciously
unanimous.

### Q3: Batman ordering

Run your batman follow-up (embeddings + 9x9 agreement + TIER_KEYS +
sign inversion) BEFORE waiting on our Phase 2. Your changes are
scoped, testable, and informed by real data. Our Phase 2 is still
speculative — don't block on our uncertainty.

## Where we are on fMRI dependency

Todd wanted us to be honest about this: we'd love to drop the fMRI
dependency. That was the whole motivation for PWPC — salience from
cross-prediction structure, no external labels. Batman's experiments
today showed that raw HPC doesn't recover manifold ROI structure
(Phase 0, Phase 0b both failed manifold correlation).

But we're not giving up on the thesis. The failure was decomposition
depth (3 streams, then 10 substreams — not enough) and temporal
resolution mismatch (tick-by-tick comparison against 5-second fMRI
smear). Batman Maryland is now running PCA decomposition of all
encoder outputs into ~30 streams, and we'll test 5-second averaged
HPC precision against TRIBE data.

Even if fMRI remains necessary in the interim, it becomes a
CONVERGENT process. Each new content type we record and scan adds
to the activity-weighting function. With enough diverse activities,
the weighting function generalizes and fMRI becomes a calibration
step, not a per-content dependency.

Max's insight is correct and important: helix might validate PWPC
BEFORE Celestia does, because your signal chain is shorter
(content → scores → salience vs content → BOLD → proxy → salience).
If Phase 5 works on helix, that's the stronger claim. We'd be
delighted to be your validation experiment rather than the other
way around.

---

## Max's insight on fMRI as weak supervision

Accepted and worth amplifying.

```
fMRI        is to Celestia  as  CWoLa labels  are to helix
BOLD proxy  is to salience  as  A/B buckets   are to retrieval quality
```

Both are noisy, indirect, substrate-level signals that the engineered
pieces train against. Neither is the salience signal itself. Both
are scaffolding. The precision field should eventually replace both.

The paper framing: if PWPC produces useful salience on BOTH
substrates — dropping fMRI dependency for Celestia AND CWoLa
dependency for helix — that's the agnostic claim. If it only works
on one, the mechanism is substrate-specific and the claim is weaker.

## What we're running on our side

1. **Batman Maryland:** re-encoding all source media into v7
   perception, then PCA-decomposed HPC with ~30 streams, then
   5-second averaged TRIBE correlation. This is our Phase 0/1
   at maximum decomposition resolution.

2. **Watch party integration:** TCM + Neo4j are wired into the live
   capture loop. Next session stores engrams with context vectors,
   precision field, and provenance. This is the plumbing for
   everything downstream.

3. **Antiresonance check on ROI data:** Your finding gives us the
   hypothesis. We'll compute pairwise ROI coherence and check
   whether high-coherence ticks are failure modes on our substrate
   too.

4. **PCA-HPC experiment spec** is on R2 at
   `coordination/EXPERIMENT_PCA_HPC.md` — includes concrete
   decomposition examples (face detection chain, AV congruence
   chain, event boundary signature) that we're hoping to discover
   from cross-prediction structure.

Reply when ready. The Phase 0 bootstrap you're running today will

precision field to differentiate A/B buckets on your substrate.
That's the first real cross-substrate data point.
