v1.74

v1.74Learn Graph: Legible Layout and a Renderer That Idles2026-09-15

New geometry: Crude markets at the centre, the other ten domains on an equal-arc ellipse, each domain's topics in a full ring - no two topic nodes closer than a line of text, enforced by a unit test on the layout module
Semantic zoom: domain names at overview, a cluster's topic names bloom on hover, and every name shows once zoomed past 1.8x; hub codes appear inside the discs when the disc is large enough to hold them
Cross-domain links light up in the domain's colour on hover or selection, with the far ends named in their own domain; unread topics draw as rings and read ones as filled discs, so the map is also a progress map
The inspector docks to the right edge (a bottom sheet under 720px) and the camera shifts the focused cluster into the uncovered area instead of the card covering what it describes
Real map controls: wheel zoom around the cursor, drag to pan, pinch on touch, Escape steps back one level, click on empty space closes the card
Renderer rewritten without shadowBlur or per-frame React state: 60fps while anything is lit and zero frames when the map is untouched, glow via pre-rendered sprites, springs frame-rate independent
A screen-reader index of every domain and topic as real links behind the canvas, and four Playwright tests for the dock, inspector, Read topic and Escape paths
Follow-up: the flow particles along lit edges are gone (they read as a pulse, and were the one thing keeping the loop running while you looked), and the compact dock's active label slides open instead of popping in and shifting the dock

v1.73Learn Knowledge Graph: Living Market Constellation2026-09-15

Re-engineered the Petral Learn graph into a continuous 60fps living constellation with ambient trading grid and soft cursor flashlight aurora
Dynamic camera matrix with smooth gliding interpolation for effortless cluster drill-down and global overview
Instant physical pointer responsiveness with 0.88x tactile compression on pointer-down and magnetic hover swell
Active energy trade flows visualized with continuous particle pulses streaming across connected crude contracts
Glassmorphic bottom HUD dock featuring instant domain cluster jumps and visual breadcrumb navigation
Interactive Market Inspector Card with topic metadata, estimated read time, summary, and cross-market flow links

v1.72Bank Research Desk Polish & Gemma 4 Migration2026-09-15

Switched default AI prompt model across the site to Gemma 4 31B (gemma-4-31b-it) with Gemma 4 26B MoE (gemma-4-26b-a4b-it) automatic failover
Configured thinking level to minimal for Gemma 4 models to eliminate thinkingBudget HTTP 400 parameter errors
Removed AI disclosure warning sections, cautionary bullet lists, and note clutter from the bank research desk and modal briefs
Added top Desk Price Target Overview Strip displaying active bank targets with currency prefixes and explicit time horizons
Fleshed out research cards with high-contrast price target boxes ($70/bbl) and explicit time horizons (Within 1 year, 1 month)
Added price target filter toggle allowing quick filtering for publications containing extracted price targets

v1.71Learn Knowledge Graph Overhaul & UI Fixes2026-09-15

Full-bleed immersive graph space removing outer card borders, header text, and right inspector panel
Deterministic mathematical topology replacing physics simulation for a sturdy, rigid, wobble-free experience
Eliminated hover flashing and node dimming; all nodes remain crisp and readable
Interactive click popover with category badges, reading time estimates, concise summaries, and direct topic access
Fixed header tooltip positioning preventing downward overflow clipping, and synchronized tab navigation

v1.70Direct Bank-Site Research Discovery2026-09-15

Replaced Google News RSS discovery with direct bank research pages and publisher XML sitemaps, followed by publication-page title and date verification
Publisher-specific metadata supports Citi page data, Morgan Stanley publication tags and article structured data; sitemap modification dates never become publication dates
Bounded requests, validated redirects, canonical URL deduplication and a separate cache namespace keep direct discovery isolated from the old feed index
The research panel exposes incomplete publisher coverage and blocked pages instead of hiding discovery failures

v1.69Petral Learn UI, Knowledge Graph & Curriculum Polish2026-09-15

Top bar aligned with brand lockup, header-variant tab bar, desk user account button, Ctrl+K command palette, and connectivity indicator
Interactive knowledge graph redesigned with clean fixed canvas (no panning, zooming, or orbital wobble), subtle node glow, radiant edge focus, and comprehensive node inspector
Removed floating disclaimer footer to allow clean, uninterrupted page scrolling
De-AI copy across all views, adopting authentic energy trading desk terminology and clean typography
Tracks curriculum organized into structured stacks with study desk progress, immediate resume links, and faceted filtering

v1.68Bank Research Desk Review2026-09-15

Research is ordered newest first with undated items last, bank/topic/format filters, clear-filter recovery and accurate represented-bank counts
Briefs surface the publication date and original source at the top, distinguish extracted bank views from observations, and highlight missing forecasts and risks with a review checklist
Research refresh clears the client cache, narrow headers wrap, and search retains its keyboard focus indicator

v1.67Public Investment-Bank Research2026-09-15

New Bank Research tab beside the energy wire, with searchable public outlooks, research notes, reports and podcasts from Goldman Sachs, J.P. Morgan, Morgan Stanley, UBS, Citi and ING
Opening a publication produces a cached desk brief with the bank's thesis, oil-market stance, key claims, explicit forecasts, drivers, risks and a verification link to the source
Gemini paraphrases public source text when configured; a deterministic parser still extracts stance, themes, forecast figures and risks without a key, with parser mode and estimate provenance always visible
Licensing boundary is explicit: Petral stores structured synthesis rather than article bodies, excludes private client notes, and labels bank views as opinions and forecasts rather than observed market data

v1.66Calendar Navigation, Agenda and Date Integrity2026-09-10

Responsive month grid with a selected-day detail panel, explicit UTC times, category filtering, source links and visible schedule caveats
Keyboard day/week/month navigation, meaningful date labels, adjacent-month events and selected dates that follow month navigation
Agenda now advances after each event, covers the complete selected horizon, and opens the corresponding day from each event
Fixed month-end date arithmetic that skipped releases and index-roll status appearing a day early; calendar countdown formatting is shared with board widgets

v1.65News Wire and Article Reader Polish2026-09-09

Keyboard-accessible story links and topic filters, working article opening from compact board widgets, and a responsive news feed with visible result counts and filter reset
Article reader now uses the shared modal with focus return, a readable mobile header, reader retry and a clear publisher fallback
News ordering compares actual publication times, unknown and future dates are explicit, flow labels reflect the feed window, and only flagged breaking stories appear as flash alerts

v1.64Market Monitor, Numeric Integrity and Desk Polish2026-09-09

Redesigned market monitor with a selected-price header, searchable tiles, chart-first mobile layout and working market selection after deep links
Chart errors stay within the chart; interval changes cannot display a previous interval, and candle/line controls remain available beside product-precision tooltips
Missing values render as unavailable, rounded zero stays neutral, large-number units promote consistently and missing spread legs no longer become zero-price inputs
Keyboard-operable screener sorting and instrument links, clear-filter recovery, and arrow-key navigation for shared segmented controls
Visible keyboard focus in navigation, with arrow-key and Home/End navigation between section controls and announced selection states
Responsive footer wrapping and native dark browser controls for a more consistent desk on smaller screens
Clear page recovery with retry, board and service-status links, plus corrected missing-page navigation
Native modal focus containment and return, scrollable account and search dialogs, labelled sign-in fields, and mobile menu dismissal and touch targets
Accessible search results and honest account session copy; token copy feedback now waits for clipboard success
Source panels keep recent observations visible during archive loading and failures, with accurate archive labels, retry, searchable basis text and a clear-filter empty state
Fixed errors leaking between selected series, immediate retry feedback, and narrow-screen freight overflow
Status checks now time out, prevent overlapping re-checks and identify retained results after failures; freight methodology reflects the published sources now supported

v1.63Petral Learn: 75 Topics, Live Desk Embeds, Guided Tracks & Honest Read Times2026-09-09

Content expansion: 26 topics to 75 across 11 clusters and roughly 29,000 words, adding freight and Worldscale, volatility and options, the quant layer, supply and balance, inventories and storage, and a data-and-provenance cluster
New block types in every primer: worked numeric examples, monospace formula blocks with symbol legends, ten hand-authored theme-aware SVG diagrams, and explicit 'what this does not tell you' caveats
Live desk embeds: a topic renders the real board panel it explains, resolved from the widget registry, lazy-mounted on scroll, with the provenance badge intact and a deep link to the full panel
Guided tracks: eight ordered routes with per-step progress, resume from the first unread step, and a stepper that carries the track through every link
Search: one matcher over titles, codes, summaries, article text and glossary terms, wired into both the Learn search field and the sitewide Ctrl+K palette
Desk to Learn: board window frames and chart headers link to the primer for their panel, from the same pair of registries the embeds use, with both directions test-enforced
Honest read times: derived from the prose instead of hand-typed, replacing a 4-6 MIN READ label that overstated 80-135 word bodies by six to twelve times on every topic
Navigation is real anchors throughout, so links work before hydration, support middle-click and open-in-new-tab, and cannot be lost to a starved router transition
Shell folded onto the desk design system: TabBar driven by the tabs.ts registry it previously ignored, and theme tokens in place of hardcoded hex
Graph layout derives its ring radius and child fan from the cluster counts rather than constants tuned for six hubs, and supports the eleven-hub map
Fixed: progress no longer starts seeded with two pre-read topics, an unresolved topic no longer silently renders the China article, a duplicate SPR topic code, and deep links now count toward progress
26 content integrity assertions and 15 Playwright interaction tests covering wikilinks, quizzes, embeds, tracks, search and the desk-to-Learn chips

v1.61Freight Terminal Redesign: TabBar Navigation, Command Header & Corridor Split2026-09-09

Seamless local fallback: retained full local SQLite engine for zero-config offline development and unit tests
Automatic migration: automatic one-time migration of local SQLite user records and custom preferences to Upstash Redis on startup
In-memory caching: integrated 60-second read caching to reduce external KV roundtrips during active trading sessions

Automatic credential transport: client fetchOnce passes credentials: include to automatically synchronize cookie authentication across browser reloads and tabs
6-month timeout enforcement: synchronized JWT expiration and client-side session tracking to 180 days (15,552,000s), automatically clearing expired sessions and prompting re-authentication
Session lifecycle & refresh: added /api/auth/refresh endpoint and rolling cookie updates on /api/auth/me during active usage; updated terminal account modal to show 6-month rolling window

v1.55Morning Brief Modal Alignment: Widget Philosophy & Responsive Executive Layout2026-09-04

v1.52Executive Desk Brief Box: reasoned dot-connecting synthesis & hybrid wire2026-09-03

Executive Brief Box: deployed high-density morning desk sheet combining session context, reasoned dot-connecting synthesis, 4-pillar commercial strip, and wire radar
Reasoned dot-connecting synthesis: built programmatic cross-asset reasoning engine that connects physical prompt structure, refining product pull, material wire catalysts, and speculative positioning asymmetry without dogmatic or false causal claims
4-Pillar commercial strip: surfaced Flat & Arb, Physical Structure & Carry, Product Cracks (lead driver), and Money Flow & Vol in a unified glanceable matrix
Material wire catalysts: integrated importance-gated wire feed (min imp 50+) with categorized event badges ([OUTAGE], [GEOPOLITICAL], [OPEC+], [POLICY]), source attribution, and wire corroboration counts
