Owner question: can score and confidence be combined into one number that is
easier to understand and for the system to decide on?
Research (pre-registered, nothing ships to the signal path):
- signals.grading_mode: "pair" (default, the shipped two-floor rule, byte-
identical: all five reference MD5s reproduce on both scripts), "min"
(min(|score|, 0.6*conf)), "product" (|score|*conf/100); thresholds fixed from
the control's corner points, no tuning. Helpers _final_signal_and_grade /
_transitioning_boost / conviction / CONVICTION_THRESHOLDS in signal_aggregator;
mirrored in K2 (GRADING_MODE_CODES, PF_conv_* packed from the live module);
twin refuses other values; M15 OOS MD5 equal on both scripts for both modes.
- Verdict: FAILED on M5 and M15. K-MIN moves 43-54 trades for -1.2R / -2.9R
(clauses a,b,e / a,b,d); K-PROD -29R on M15 (PF 1.29, W3 DD 28.9R), neutral
on M5. H1/H4 product +11.9R / +17.0R on W3 from extra low-score trades
(H1 PF 1.98 -> 1.75, DD doubles): hypothesis only.
- Code review (high) before the runs: 6 findings fixed, 1 recorded
(engine_config_fingerprint omits the switch under "pair", so live rows keep
their fingerprint).
Delivery (books untouched): alerts lead with the grade and print the two raw
numbers in words (main.plain_words: "Direction: strong buy · Reliability: good
· timeframes agree", cut-offs = the grade table's own) on Telegram, /status,
the CLI and the dashboard card (plain_words in the snapshot); "MTF" label
replaced by "Other timeframes"; guides updated. Suite 566 passed.
Evidence: backtest/research/conviction_campaign_2026-09-27.md
One card per timeframe (M5/M15/H1/H4) in a Bootstrap column grid, above a
direction board that charts every timeframe's score as a diverging bar.
Each card carries its own indicator-vote chart, and the newswire gets a
headline-tone bar. Bootstrap Icons and the hand-rolled CSS gauges are gone;
dashboard.css is now the token set plus the app-specific pieces only.
Chart marks use a diverging pair validated on this surface (#0d9f7a /
#e8503a: lightness band, chroma floor, colour-vision separation, contrast).
Lighter steps of the same two hues carry the colour where it has to work as
text, and direction never travels as colour alone -- an arrow icon and the
word ride with it.
Behaviour is unchanged: same snapshot.json / news.json contract, the same
coordinated refresh loop (boundary poll, 60 s fallback, 15 s retry,
in-flight guard, stale-snapshot guard), per-timeframe change detection,
modal state preservation, HTML escaping, the news_summary.php contract and
the warming / scan-failed / weekend states. Nothing on the signal path is
touched, so no book moves.
Verified headlessly against a fixture replayed through the real signal code
(wide / laptop / tablet / mobile, both dialogs, every degraded state): no
console errors, html-validate clean.
Suite 553 -- the old static-UI test splits into one that pins the CDN stack
and one that pins a card and a chart per timeframe against
dashboard_publisher.DASHBOARD_TFS.
Page now uses Bootstrap 5.3 color modes (data-bs-theme), Bootstrap Icons,
and Bootstrap modals. Custom code shrinks to dashboard.css (app tokens,
score bar, signal accents) and dashboard.js (rendering/polling logic,
ported verbatim from the inline script). dashboard_publisher copies the
new css/js into the docroot; all 381 tests still green.
