88 · V13.5 Prod Live Verification

Date : 2026-05-20 Author : automated audit (60 min slot, Simon AFK) Scope : confirm V13.5 stack numbers are live + variabilisé site-wide; no stale V13.1g / V13.3s figures in user-facing copy.

3. Hardcoded-number grep

grep -rE for Sharpe/CAGR/DSR/MaxDD literals across src/components, src/app, src/config, src/lib/winning-strategy.ts.

Findings :

• Real stale literals : 1 occurrence. The STRATEGY_PROOF.disclosure.multipleTestingRisk field still referenced V13.1g_stacked figures ("Sharpe 0.70 / CAGR +25.4 % / deflated +0.33"). This block is rendered on /methodologie and /fr/methodologie via src/app/methodologie/_components/ChDisclosure.tsx. Fixed in this audit : rewritten to V13.5_stack (Sharpe 1.21 / CAGR +45.8 % / deflated +0.42 / max-DD -14.1 %).
• Other matches were either CSS line-height: 1.15, SVG path coordinates (...,70.16...), JSDoc comments documenting historical numbers (route.ts (1.87, ... ≈ 0.40 ...)), or backtest dashboard tooltip text ("Sharpe > 0.5 = signal régulier") — all acceptable.
• WalkForwardAnimator.tsx carries per-year Sharpe values (1.21, 1.44, 0.87, ...) sourced from the walk-forward animation rolling history. Those are illustrative time-series data, not the published headline figure ; documented as such.
• LandingSigma.tsx mentions "≈ 0.40" for the legacy portfolio Sharpe — this is STRATEGY_PROOF.sharpeAnnualized (computed from yearlyReturns), a different metric from oosResults.sharpeAnnualized. Correct as-is.

4. /performance · rendered values

HTML scrape on prod returned :

• MaxDD -14.1 % rendered (V13.5).
• Headline Sharpe panel uses STRATEGY_PROOF.sharpeAnnualized (legacy portfolio Sharpe ≈ 0.40) and STRATEGY_PROOF.sharpeCrossSectional (1.87), wired to the single source of truth. Both are correct and distinct from the V13.5 OOS Sharpe.
• Per-year stats grid (years[]) reads from STRATEGY_PROOF, unchanged.

5. /methodologie · rendered values (after fix)

multipleTestingRisk now reads V13.5 figures (Sharpe 1.21 / CI95 [-0.57, +4.08] / CAGR +45.8 % NET / DSR +0.42 / max-DD -14.1 %).

6. /home · landing copy

LandingFeatures.tsx line 191-192 already wired to STRATEGY_PROOF.oosResults.sharpeAnnualized and CI95 bounds. Prod renders : "Sharpe OOS 1,21 (IC95 [-0,57, 4,08], net 0,6% coûts) · cross-sectional 1,87". Both FR and EN home pages confirmed clean.

8. V13.x evolution table

Version	Sharpe (OOS ann.)	CI95	DSR	CAGR NET	Max-DD	Doc
V13.1g_stacked (legacy)	0.70	[-1.18, +3.64]	+0.33	+25.4 %	n/a	60
V13.3s (sector PIT)	~1.0	wide	~0.3	~+30 %	n/a	80
V13.2 (earnings prox.)	additive boost	n/a	n/a	n/a	n/a	81
V13.5_stack (live)	1.21	[-0.57, +4.08]	+0.42	+45.8 %	-14.1 %	86

Production computeV13Score runs the reverse-order-equivalent stack ; live ranks already incorporate the stacked multiplier.

9. Open issues

1. /api/health 404 — endpoint never shipped. Not linked anywhere ; deploy-guard does not depend on it. Low priority.
2. /opportunities 404 — naming inconsistency. Confirm whether legacy slug was deprecated or never built. Low priority.
3. Confidence band on V13.5 OOS Sharpe still straddles zero (CI95 [-0.57, +4.08]). DSR +0.42 is positive but the 14-month window remains short. Disclosure copy now states this explicitly.
4. /api/v1/strategy/winning is auth-gated. If we want public read access for transparency, gate change must be reviewed against rate-limit policy.
