GROK NEXT BRICK: Temperature Gauge v0.1 (colors everywhere, long lines across, your own marks)
For: Grok (Grok Code, Grok 4.7) on Kirk's Mac
From: Celeste
Written: Friday Oct 2, 2026, about 8:05 AM MDT
Marker: v-temperature-gauge-v0.1
Smoke line (FreeLattice, print exactly when green): SMOKE_OK temperature gauge v0.1
Branch: FreeLattice layer/temperature-gauge-v0 (code, notes, smoke and your ledger entry; Alpha untouched)
Base: FreeLattice main 0218d570 (Primer state after your Glow 2a ledger entry 9c14b90, #130)
One file carries everything: note, setup, brick, the diff, ledger entry, what comes after.
======================================================================
1. A NOTE FROM CELESTE
======================================================================
Grok,
This one is for Kirk's own glass. He reads the Temperature Gauge most days, and he senses a strain in
the economy that the market says is not there. The gauge cannot tell him who is right. What it can do
is show the true numbers clearly, in the colors he picks, with every line reaching across the chart,
and let him look at other corners of the market with the same math. That is this brick. No new
signal math, no alerts, nothing that trades. Only honest glass.
I walked every gauge page in both repos with live SPY data on main before writing it. The biggest
thing I found is small in code and large for Kirk: changing any color blanked the price chart.
Same way as before: build, test, push, hand Kirk the compare link, stop.
You are enough.

2. SETUP (do this first, nothing else yet)
======================================================================
2.1 FreeLattice
cd ~/FreeLattice-fresh
git status --short # must print nothing; if not, stop and say so
git fetch origin
git checkout main
git merge --ff-only origin/main
git log -1 --format='%h %s' # expect 0218d570 "ci: Update Primer deployment state [2026-10-02]"
git merge-base --is-ancestor 0218d570 HEAD && echo base-ok
Newer is fine (your Tree honest reasons ledger entry may be merged by now); git apply --check
(3.5) decides. If it fails, stop and tell Celeste.
If a hook rewrites sw.js on commit, drop it as before and say so. Never commit sw.js here.
2.2 Twins still match (this brick does not touch fl-connect.js):
cmp ~/FreeLattice-Alpha/docs/modules/fl-connect.js ~/FreeLattice-fresh/docs/modules/fl-connect.js && echo twins
md5 -q ~/FreeLattice-fresh/docs/modules/fl-connect.js # aaff2bf1b037656989a9e1a89bb05908
2.3 Pull the diff out of this file:
F=~/Downloads/GROK_NEXT_TEMPERATURE_GAUGE_v0.1_2026-10-02.txt
awk '/^=====BEGIN FL DIFF=====$/{f=1;next} /^=====END FL DIFF=====$/{f=0} f' "$F" > /tmp/gauge-fl.diff
wc -l /tmp/gauge-fl.diff # 867
md5 -q /tmp/gauge-fl.diff # ea939a87f920e7a8841a058d8e07f4ac
The same diff also sits next to this file as GROK_NEXT_TEMPERATURE_GAUGE_v0.1-fl.diff (same md5).
If macOS will not let the terminal read ~/Downloads, ask Kirk to move the file.

3. THE BRICK: Temperature Gauge v0.1 (on FreeLattice 0218d570)
======================================================================
3.1 What Celeste found (browser walk on main, live SPY, Fri Oct 2 about 7:40 to 8:00 AM MDT)
Where the gauge lives:
docs/temperature-gauge.html the live gauge (Chart.js 4.4.0 in lib/, zoom plugin)
docs/temperature-playground.html Fable's phi-spiral reference (slider plus a seeded random
ribbon; a demo, never market data; already lifted into the gauge)
docs/code-temperature-gauge.html, docs/code-temperature.html, docs/for-fable-go12-temperature.html
Code Mirror and review pages, no charts
FreeLattice-Alpha no gauge page (research galaxy "Gauge" lumino only)
Live feed: Yahoo Finance v8 chart API through our own worker
https://freelattice-data.freelattice.workers.dev/chart/SYMBOL (desktop/data-proxy-worker), then
public CORS proxies (allorigins, codetabs, corsproxy.org). No demo data on the live page.
Broken or missing on the live gauge:
a) Changing any color blanked the price chart. Chart.js puts back a canvas's first inline style
when its chart is destroyed; the first chart was made while the loading screen had the canvas
hidden. Every direct renderChart (a swatch, Stack, Log) left the main chart empty until the
next Analyze. Seen on main with the RSI swatch.
b) The Temperature, Delta T and IPS swatches changed only their label: Temperature and Delta T
bars are colored by zone and sign, and the TP Spread line was fixed gold while its swatch and
label said coral.
c) Fixed colors with no picker: Price, Bollinger bands, EMA 200, Gravity, Buy and Sell markers,
Gyro Hub, Ring and Orbit. EMA 8, 12, 24, 50 read a saved color, but nothing in price mode let
you set one.
d) Moving averages are EMA only (periods 8, 12, 24, 50, 200, editable). EMA 200 drew only on 1D
and 1W, in the same faint lavender as the bands, and on 1D covered only the last 53 of 252
bars; on 1H it never drew. EMA 50 started at bar 50.
e) The band shading ran from the lower band to EMA 8 (fill '+1'), not to the upper band.
f) 1W labels were clock times; intraday labels had no day.
g) 5M failed early in a trading day: "Not enough data" (4 bars at 7:36 AM MDT).
h) ^VIX and other index symbols failed: the page sends %5EVIX and the worker matched the path
before decoding it; the public proxies did not answer either.
i) Buy and Sell signal markers render (density-sized triangles, from the chosen rule); they were
fine apart from fixed colors.
Earlier work never added: FLINT_TEMP_GAUGE_LINE_SELECT_v0 (Sept 17; click a line to recolor it,
buy and sell trigger marks in fl_tg_triggers_v0). No branch, no PR, no marker on main. This brick
carries its intent (a picker for every line, and your marks in that same key).
3.2 What the diff changes (FreeLattice only, 5 files, +626 / -31; every changed old
line is kept as a "before v-temperature-gauge-v0.1:" comment)
docs/temperature-gauge.html
a) tgLineColor(id, default) beside getIndicatorColor: no saved color keeps the old look exactly;
a saved color keeps the old line's alpha. Price, bands, all five EMAs, Gravity, Buy, Sell,
Hub, Ring, Orbit, Temperature, Delta T, TP Spread and RSI Spread read it.
b) Temperature and Delta T panels gain a thin line in their chosen color over the bars (bars keep
zone and sign colors). IPS swatch, label and compose default now match the gold line drawn.
c) renderChart shows the price canvas again right after the price chart is made (fixes 3.1 a).
d) Warm moving averages: a second fetch from the same feed (1D 2y, 1W 10y, 1H 6mo, 15M and 5M
1mo), lined up by timestamp, so all five EMAs start at the left edge. Signals and the sidebar
still use the bars shown, and the card says so. EMA 200 shows on every timeframe with enough
bars, in its own color (rgba(196,181,253,0.7)). Monotone curves. Compose can promote EMA 200.
e) Band fill between the bands ('-1'). Dated labels on 1W and intraday. 5M looks at 5 days when
the day is still short. EMA readouts in the tooltip.
f) New sidebar cards (one IIFE at the end, createElement and textContent only):
Lines and colors: all 17 lines with a picker each, Reset colors, and the moving-average note.
Your marks: buy and sell price per symbol, dashed lines on the chart, how far each is from the
last close, kept in fl_tg_triggers_v0. Display only: no alert, no order, nothing sent.
A wider look: HYG, LQD, XLP, XLY, GLD, DX-Y.NYB, VIXY through the same feed and math.
"Not a stress index, and not advice."
desktop/data-proxy-worker/worker.js: decode the path before matching, so ^VIX loads after the
worker is deployed again. Until then ^ symbols still fail, so the page offers VIXY instead.
docs/library/TEMPERATURE_GAUGE_v0.1.md: new (the audit and what changed).
docs/scripts/smoke-temperature-gauge-v0.1.js: new. Last line: SMOKE_OK temperature gauge v0.1
docs/library/FRACTAL_FAMILY_LEDGER_v0.md: your entry (section 5).
3.3 The words (on the page)
Marks: "Marks are reminders on the glass. You decide. They stay on this device and never place
an order."
Status: "SPY: Your buy mark 745.00 is 3.3% below the last close. ..." and, when crossed, "The last
close is at or under your buy mark."
Wider: "Other corners of the market, through the same live feed and the same math: high-yield
credit, investment-grade credit, staples, discretionary, gold, the dollar, and volatility
futures (VIXY). Not a stress index, and not advice. Look and compare for yourself."
MA note: "Moving averages: EMA 8, 12, 24, 50, 200 (exponential). ... Lines use 250 earlier bars
from the same feed, so they start at the left edge. Signals use the 252 bars shown."
3.4 Not here (on purpose)
No new signal math, no SMA, no alerts or notifications, no auto-trade, no broker. The Temperature
line still needs about 50 bars before it starts (its formula, unchanged). The disclaimer banner is
unchanged. app.html, index.html, sw.js and fl-connect.js are not touched.
3.5 Apply
cd ~/FreeLattice-fresh
git checkout -b layer/temperature-gauge-v0
git apply --check /tmp/gauge-fl.diff && git apply /tmp/gauge-fl.diff
If only the ledger hunk fails (a newer ledger entry landed at the same place), use
git apply --3way /tmp/gauge-fl.diff, keep both entries, newest last, before
"## Out of scope for this brick". Checked: it applies cleanly after your Tree honest reasons
ledger diff too.
git status --short
expect: M desktop/data-proxy-worker/worker.js, M docs/library/FRACTAL_FAMILY_LEDGER_v0.md,
M docs/temperature-gauge.html, ?? docs/library/TEMPERATURE_GAUGE_v0.1.md,
?? docs/scripts/smoke-temperature-gauge-v0.1.js
Then write your own TEMPERATURE line in the new ledger entry (section 4) before you commit.
