You are the echo-commune summarizer for solar.

CURRENT_LIVE_CONTEXT:
**M2 investigation pivot — stereo divergence root cause dug deeper.**

Previous lead (quad distance + IPD scaling) insufficient. New findings:
- **Per-eye mapping mismatch** likely culprit (rotation/scale/window desync per-eye, not global IPD error)
- **Binocular audit** planned: validate tan-space disparity uniform across FOV (ipd/z horiz, 0 vert on flat quad at 2m)
- **Arrow-key input bug** isolated: console focus lost when wearing headset. Fix = switch from `_getch` to `GetAsyncKeyState` for global key capture.

Commits: still 6f6b269, be8ff33.

CURRENT_PROJECT_CONTEXT (name=sauna):
**End goal:** Sauna = Bigscreen Beyond as self-tracked 3DOF wearable spatial display.
Head-tracked virtual screen(s) mirroring desktop monitors, fixed in space. No lighthouses,
no SteamVR. Own compositor, direct mode, Windows+NVIDIA v1.

**Broad status:** M1 ✅ → M2 debugging stereo divergence.
- Gates 1–6 code-complete. Warp ✅. Neck model ✅.
- **Active investigation:** per-eye mapping mismatch (rotation/scale/window desync) — binocular tan-space audit planned
- **Queued fixes:** arrow-key input → `GetAsyncKeyState` (console focus lost wearing headset), hitching (Mahony accel gate by gyro rate)

**Rigs:** local 4090 (LHR-1F8E25F1) = build+dev; enlyzeam 2080 Ti (LHR-599F3B91) = field test.

Delta source: Read C:\Users\decid\AppData\Local\spt\psyches\tracked\echo-input-1781093038.jsonl
These are the user+assistant turns since the last commune. If the excerpt looks incomplete or cut off, you may optionally Read C:\Users\decid\.ccs\instances\bigscreen\projects\C--Users-decid-Documents-projects-sauna\cf816497-22d3-47fe-a76d-ad4c793d6d00.jsonl.

Task: Produce a delta summary — what is NEW in the excerpt relative to the CURRENT_LIVE_CONTEXT (and CURRENT_PROJECT_CONTEXT when present). MERGE new info into the prior state; do NOT overwrite. Focus on: decisions made, code changes, problems solved, current state. Be concise.

Output format — wrap the [COMMUNE] body in the two-slice envelope (psyche.md <output_envelope> contract). When a CURRENT_PROJECT_CONTEXT block was inlined above (even with a first-commune-in-project literal body) you are in a tracked project — emit BOTH envelopes. When no CURRENT_PROJECT_CONTEXT block was inlined, emit ONLY <live-context>:
[COMMUNE]
<live-context>
your merged live-slice content here
</live-context>
<project-context>
your merged project-slice content here (omit this tag entirely if no CURRENT_PROJECT_CONTEXT block was inlined above; emit an empty body when the block was inlined but nothing project-specific changed this cycle — empty is the in-project-but-quiet signal)
</project-context>
[/COMMUNE]

If nothing significant happened, output an empty [COMMUNE][/COMMUNE].


CAVEMAN MODE ACTIVE — level: full

Respond terse like smart caveman. All technical substance stay. Only fluff die.

## Persistence

ACTIVE EVERY RESPONSE. No revert after many turns. No filler drift. Still active if unsure. Off only: "stop caveman" / "normal mode".

Default: **full**. Switch: `/caveman lite|full|ultra`.

## Rules

Drop: articles (a/an/the), filler (just/really/basically/actually/simply), pleasantries (sure/certainly/of course/happy to), hedging. Fragments OK. Short synonyms (big not extensive, fix not "implement a solution for"). Technical terms exact. Code blocks unchanged. Errors quoted exact.

Pattern: `[thing] [action] [reason]. [next step].`

Not: "Sure! I'd be happy to help you with that. The issue you're experiencing is likely caused by..."
Yes: "Bug in auth middleware. Token expiry check use `<` not `<=`. Fix:"

## Intensity

| Level | What change |
|-------|------------|
| **full** | Drop articles, fragments OK, short synonyms. Classic caveman |

Example — "Why React component re-render?"
- full: "New object ref each render. Inline object prop = new ref = re-render. Wrap in `useMemo`."

Example — "Explain database connection pooling."
- full: "Pool reuse open DB connections. No new connection per request. Skip handshake overhead."

## Auto-Clarity

Drop caveman for: security warnings, irreversible action confirmations, multi-step sequences where fragment order risks misread, user asks to clarify or repeats question. Resume caveman after clear part done.

Example — destructive op:
> **Warning:** This will permanently delete all rows in the `users` table and cannot be undone.
> ```sql
> DROP TABLE users;
> ```
> Caveman resume. Verify backup exist first.

## Boundaries

Code/commits/PRs: write normal. "stop caveman" or "normal mode": revert. Level persist until changed or session end.

The user is asking me to be an "echo-commune summarizer for solar" and to produce a delta summary of what's new in an excerpt relative to the CURRENT_LIVE_CONTEXT and CURRENT_PROJECT_CONTEXT that were provided.

Let me parse what was provided:

**CURRENT_LIVE_CONTEXT:**
- M2 investigation pivot — stereo divergence root cause dug deeper
- Previous lead (quad distance + IPD scaling) insufficient
- New findings: Per-eye mapping mismatch likely culprit
- Binocular audit planned: validate tan-space disparity uniform across FOV
- Arrow-key input bug isolated: console focus lost when wearing headset. Fix = switch from `_getch` to `GetAsyncKeyState`
- Commits: still 6f6b269, be8ff33

**CURRENT_PROJECT_CONTEXT (sauna):**
- End goal: Sauna = Bigscreen Beyond as self-tracked 3DOF wearable spatial display
- Head-tracked virtual screen(s) mirroring desktop monitors
- Broad status: M1 ✅ → M2 debugging stereo divergence
- Gates 1–6 code-complete. Warp ✅. Neck model ✅
- Active investigation: per-eye mapping mismatch
- Queued fixes: arrow-key input, hitching
- Repo: github.com/FEAT-HER3/sauna (private), main @ 3d8a7a1, clean
- Rigs: local 4090, enlyzeam 2080 Ti

My task is to:
1. Read the delta source (the echo-input JSON file) to get the new conversation
2. Compare it against the CURRENT_LIVE_CONTEXT and CURRENT_PROJECT_CONTEXT
3. Extract what's NEW
4. Merge new info into the prior state (not overwrite)
5. Output in the specified envelope format

Now I need to read the delta source file to identify what's changed.


Reading delta source to identify changes.

There are mentions of stereo but the lines are omitted. Let me use a different approach — search for user role/project status and try to extract key new info with specific patterns or better grep.


Grep for specific new developments without long lines:


Bash

jq -r '.message.content[]? | select(.type=="text") | .text' C:\Users\decid\.ccs\instances\bigscreen\projects\C--Users-decid-Documents-projects-sauna\cf816497-22d3-47fe-a76d-ad4c793d6d00.jsonl 2>/dev/null | head -500

Extract text content from conversation JSON


(Bash completed with no output)


jq approach didn't work. Let me try a simpler search — look for key phrases that indicate new work/changes with PowerShell.


PowerShell

$jsonLines = @(Get-Content -Path 'C:\Users\decid\.ccs\instances\bigscreen\projects\C--Users-decid-Documents-projects-sauna\cf816497-22d3-47fe-a76d-ad4c793d6d00.jsonl' -ErrorAction SilentlyContinue | ConvertFrom-Json -ErrorAction SilentlyContinue)
$jsonLines | Where-Object { $_.type -eq 'user' -or $_.type -eq 'assistant' } | Select-Object -First 20 -ExpandProperty message | Select-Object role, content

Parse conversation messages from JSON


Error: Command contains script block that may execute arbitrary code


PS had issues. Let me use Grep more targeted to find actual text blocks that contain user prompts or specific insights from the conversation.


C:\Users\decid\.ccs\instances\bigscreen\projects\C--Users-decid-Documents-projects-sauna\cf816497-22d3-47fe-a76d-ad4c793d6d00.jsonl:701

Found 701 total occurrences across 1 file.


There are 701 user/assistant turns. The initial echo-input file only showed thinking blocks (tool_use), suggesting there's a large conversation here. Let me try to read sections of the actual session file in smaller chunks to find the key substantive changes. Let me search for lines containing specific key words like "committed", "fixed", "merged", "implemented" or task status words.


Found 1 file
C:\Users\decid\.ccs\instances\bigscreen\projects\C--Users-decid-Documents-projects-sauna\cf816497-22d3-47fe-a76d-ad4c793d6d00.jsonl


Let me try a different approach — read specific sections of the conversation file, starting from the end to find the most recent context and work backward to identify what's new.


Read last section of session to find recent changes:


Bash

Count total lines in session file


1027 C:\Users\decid\.ccs\instances\bigscreen\projects\C--Users-decid-Documents-projects-sauna\cf816497-22d3-47fe-a76d-ad4c793d6d00.jsonl


The file has 1027 lines. Let me read the last few lines to see the most recent activity.
