2. The Envelope page
Every tile, line, control and chart element of the home page.
The Envelope page, from top to bottom
The page reads from top to bottom like a short report.
The header has the page title, a one-line status of the data behind it, the + Add a source button and the ? menu.
The Ask box is one line. Type a question about a condition and press Ask, or leave it and use the tiles.
The four scenario tiles are ready-made conditions: the ISS cabin, NASA's Moon Base, a NASA exploration atmosphere, and Your condition. Click one to load it.
The three columns are the controls on the left, the evidence chart in the middle, and on the right the verdict and the list of where the evidence is. The left and right columns scroll by themselves, so the chart stays in view.
The result cards under the columns hold one card per investigation, with the reasons and the receipts.
Reading a scenario tile, line by line
Take NASA's Moon Base.
The title names the scenario, and the line under it says where it comes from. The condition line gives oxygen, pressure and gravity with units. A pressure the source writes as "psi" stays "psi", with a hover note that it is absolute pressure.
The bold line says how many investigations apply and how many need extrapolation, or, when none applies, the headline of the chart. For the Moon Base it reads "No PSI test in this gravity regime".
The smaller lines give more: the closest solid-fuel investigation that can be compared and how many others lack the values, or, for the exploration atmosphere, what microgravity would give for the same atmosphere.
The quote on the Moon Base tile is from NASA's FM2 page, with a link. The button What would close this gap opens the plan of experiments (chapter 5). Hover a tile for its sources.
The tones of the map
Behind the outlines and points the chart is shaded. The shading is the evidence map of the regime you selected.
Bright cyan means that at least one investigation applies there: it tested the same regime and covers that oxygen and pressure. The brighter, the more investigations.
Three violet tones mark extrapolation by distance from the tested data: just outside, outside and far outside. They are steps of distance, not degrees of safety.
A hatch marks a combination that was never tested although each setting was tested on its own.
Dark means no investigation of this regime covers the point.
Hover the chart to read which investigations apply at the cursor.
Full screen, zoom and pan
The Full screen button opens the chart over the whole window with a sidebar listing where the evidence is. Esc returns you to the page, with the same view.
Pan by dragging anywhere on the plot. Move the target by dragging from its marker, or by clicking without moving. Zoom with the plus and minus buttons, with the wheel in full screen, or with Ctrl and the wheel on the page. The arrow keys pan, plus and minus zoom, and 0 resets.
The axes always show their units and add psia once the view is zoomed. Zoom and pan change only what you see; no verdict changes.
Ask button
What it is. The button of the Ask TARS SI bar.
What it shows. Nothing by itself.
How to use it. Press it to open TARS SI and send your question.
Example. Press Ask after typing a question.
What it does not do. It does not change the chart; use Show on the envelope in TARS's answer for that.
Ask TARS SI bar
What it is. The single question bar at the top of the Envelope page.
What it shows. Rotating example questions; nothing is computed until you send one.
How to use it. Type a question and press Ask: TARS SI opens with the question already sent.
Example. Ask what PSI says at 34 % oxygen and 8.2 psia.
What it does not do. It does not decide anything itself: TARS reads the condition by code, and the engine writes every verdict.
Question box
What it is. The text box of the Ask TARS SI bar.
What it shows. Example questions that rotate while it is empty.
How to use it. Type your question, with numbers and units if it is about a condition.
Example. Would solid fuel burn differently in a lunar base at 30 % oxygen and 10.2 psi?
What it does not do. It does not run the engine on its own; it hands the question to TARS SI.
The Envelope page and its chart
The Envelope page is the home page. The chart plots oxygen (% by volume) against pressure (kPa). Each shaded outline is the envelope of one regime: the oxygen and pressure range that PSI tested for one combination of gravity, fuel phase, diluent and flame type.
Your condition is the target marker. Click the chart, drag the marker or use the controls on the left to move it. Dragging elsewhere pans the view; Ctrl and the wheel, or the + and - buttons, zoom.
Inside an outline means that oxygen and pressure lie within the region spanned by an investigation's test points (between tests, not necessarily tested at that exact point). Outside means beyond every extracted PSI test region.
The three big tools (line on the Envelope page)
What it is. One line of links under the scenario tiles.
What it shows. Three links: Mission Planner (what would close the Moon gap), Investigations (the 24 PSI studies) and TARS SI (ask the AI assistant).
How to use it. Click one to open that page.
Example. Click Mission Planner to see how much of the Moon Base band PSI covers.
What it does not do. It does not change the condition you have chosen.
The four scenario tiles
The strip at the top of the Envelope page has four tiles. Click one to load it into the dashboard.
ISS cabin air, NASA's Moon Base (as stated in the Flame in Freefall challenge) and the NASA exploration atmosphere (from an NESC report) are conditions NASA has written down; hover a tile for its source. "Your condition" shows the current controls.
Every number on a tile is computed live by the engine on the real records. Changing any control leaves the preset and lights "Your condition".
The evidence map (shading)
Under the chart's outlines, the shading is the evidence map for the selected regime. Bright cyan means NASA investigations apply there; brighter means more of them. Violet means only extrapolation, in three steps by distance from the tested data (just outside, outside, far outside), with a hatch for an untested combination. Dark means no investigation of that regime covers the point.
Hover the chart to see which investigations apply at the cursor.
Full screen, zoom and pan
The Full screen button opens the chart over the whole window with a sidebar listing where the evidence is. Esc or "Exit full screen" returns to the page with the same view.
Drag anywhere to pan. Drag from the target marker to move the target. A click without movement places the target. In full screen the wheel zooms around the cursor; on the page, hold Ctrl. The arrow keys pan, + and - zoom, 0 resets. Zoom and pan change only the view, never a verdict.
Command palette search box
What it is. The text box inside the command palette.
What it shows. What you type, filtering presets, sections and pages.
How to use it. Type a few letters, use the arrow keys, press Enter to go.
Example. Type "lunar" and press Enter to load NASA's Moon Base.
What it does not do. It only jumps to things inside PYRION; it does not answer questions.
Command palette result
What it is. One entry of the palette list: a preset, a section or a page.
What it shows. Its group and its label.
How to use it. Click it or press Enter on it to run it.
Example. Click "ISS cabin air" to load that scenario.
What it does not do. It does not change anything until you pick it.
Status bar at the page foot
What it is. The row of small status cells above the footer.
What it shows. Facts about the checks behind this build, for example the validation result.
How to use it. Read it to see the state of the evidence pipeline; hover a cell for its meaning.
Example. Look at "Validation: 0 critical findings".
What it does not do. It is not live monitoring of the site, only the last committed report.
Envelope page overview
What it is. The home page: choose a condition, see where NASA's tests stand relative to it, and read the verdicts.
What it shows. From top to bottom: header line, Ask box, four scenario tiles, the controls, the chart, the verdict and the list "Where the evidence is", then the result cards for every investigation.
How to use it. Pick a tile, or set oxygen, pressure and gravity by hand, and read the headline.
Example. Click "NASA's Moon Base" and look at the headline.
What it does not do. It never says a condition is safe or validated; it says what PSI contains.
Header status line
What it is. The one small line under the page title.
What it shows. How many condition values were extracted, from how many investigations, and whether each is located in the NASA source by code.
How to use it. Read it to know how much data stands behind the page; click details for the breakdown.
Example. records in the files, how many the engine uses after rejections, and how many investigations they come from. Every count says what it counts.
What it does not do. It does not say the data is complete: six investigations have no extracted values yet.
Details link in the header
What it is. A link beside the status line.
What it shows. Opens the Data page.
How to use it. Click it for the full count and lineage.
Example. Use it to see how many values are located cell by cell.
What it does not do. It does not change the Envelope page.
Scenario tiles
What it is. The row of four tiles under the Ask box.
What it shows. ISS cabin air, NASA's Moon Base, NASA exploration atmosphere and Your condition, each with live numbers.
How to use it. Click a tile to load it into the dashboard; hover it for its sources.
Example. Click the exploration atmosphere tile.
What it does not do. The numbers are computed by the engine for exactly that condition; they are never typed in.
Tile title (loads the scenario)
What it is. The title and condition of a tile, which is also the button that loads it.
What it shows. The scenario name and its condition line.
How to use it. Click it to apply that scenario to the controls and the chart.
Example. Click "NASA's Moon Base".
What it does not do. Loading a scenario replaces the current controls; Your condition shows them again if you change anything.
Tile title
What it is. The name of the scenario.
What it shows. ISS cabin air, NASA's Moon Base, NASA exploration atmosphere or Your condition.
How to use it. Read it to know what the tile represents.
Example. Moon Base is NASA's stated band, not a measurement.
What it does not do. It is not a recommendation.
Tile subtitle
What it is. The small line under a tile title.
What it shows. Where the condition comes from, for example "as stated in the Flame in Freefall challenge".
How to use it. Read it before trusting a tile.
Example. The exploration tile cites its NTRS document.
What it does not do. It is not a quote of the full source; hover the tile for that.
Tile condition line
What it is. The monospaced line of numbers on a tile.
What it shows. Oxygen, pressure and gravity of the scenario, with units. A pressure the source writes as "psi" stays "psi" with a hover note that it is absolute.
How to use it. Read it to compare scenarios at a glance.
Example. "34 % O₂ · 8.2 psia · 0.16 g".
What it does not do. It is the condition PYRION tests against PSI, not a prediction about it.
Tile verdict summary
What it is. The bold line on a tile.
What it shows. How many investigations apply, split by fuel phase, and how many need extrapolation; or, when none apply, the headline of the chart.
How to use it. Read it to see how much evidence PSI holds for that scenario.
Example. "4 applicable (3 gas fuel, 1 liquid fuel)".
What it does not do. Applicable means the oxygen and pressure lie within the region spanned by PSI test points in the same regime (between tests, not necessarily tested at that exact point); it does not mean the condition is safe.
Tile detail line
What it is. A smaller line below the summary on a tile.
What it shows. A computed fact such as the closest solid-fuel investigation, or what microgravity would give for the same atmosphere.
How to use it. Read it for the next level of detail.
Example. "Closest solid-fuel investigation that can be compared: BASS, just outside the tested data".
What it does not do. It names only investigations the engine could compare; the others are counted, not guessed.
NASA quote on a tile
What it is. An italic line quoting NASA.
What it shows. A sentence from NASA's FM2 page about lunar gravity, with a link.
How to use it. Click the link to read the page.
Example. "materials may burn at lower oxygen concentrations in lunar gravity compared to Earth".
What it does not do. It is a quotation, not a PYRION finding.

About this scenario
What it is. A collapsible note under the tiles.
What it shows. The chosen scenario's description, its sources and limits.
How to use it. Click to open it.
Example. Read the limits of the ISS preset.

What it is. The left column of controls.
What it shows. Oxygen, pressure, gravity regime and the other axes.
How to use it. Change any control to test your own condition.
Example. Move pressure to 70 kPa.
What it does not do. Changing a control leaves the preset: the result then says "your condition".
Oxygen number box
What it is. A number box for oxygen in percent by volume.
What it shows. The current oxygen level.
How to use it. Type a value between the window limits.
Example. Type 34.
What it does not do. It is the ambient oxygen of the target, not a partial pressure.

What it shows. The same pressure with ticks at 8.2, 10.2 and 14.7 psia.
How to use it. Drag it.
Example. Drag to the ISS tick.
What it does not do. The ticks are NASA conditions, not safe limits.
Regime selects (gravity, fuel phase, diluent, flame type)
What it is. The drop-downs for the regime axes.
What it shows. The value of each axis, or "left open".
How to use it. Choose a value to compare only tests in that regime; leave an axis open if you do not know it.
Example. Set gravity to microgravity.
What it does not do. A regime is a barrier: tests in a different regime are not compared. An axis left open is not compared, and an investigation that did not record it may become insufficient evidence.
Gravity level box
What it is. A number box shown for partial gravity.
What it shows. The gravity level in g, for example 0.165.
How to use it. Type a level.
Example. Type 0.165 for the Moon.
What it does not do. It is shown only; no PSI test is at a partial-gravity level, so it is not compared.
Evidence envelope card
What it is. The card that holds the chart and its controls.
What it shows. The legend, the chart, the target callout, the map legend and a data table.
How to use it. Use its buttons to zoom, pan or open it full screen.

What it shows. For each investigation, the smallest outline holding its measured oxygen and pressure points.
How to use it. Check whether your target marker is inside an outline of the right colour.
Example. Move the target into a green-teal outline.
What it does not do. Inside an outline in a different regime does not count: regimes are barriers.
Measured points
What it is. The dots, triangles and squares on the chart.
What it shows. One mark per extracted oxygen and pressure pair of a test.
How to use it. Hover for the test, click for its receipt.
Example. Hover a point to see its investigation.

What it shows. Your condition on the chart.
How to use it. Drag it to move the target; click elsewhere to place it.
Example. Drag it to 8.2 psia.
What it does not do. It is a condition you chose, not a measurement.
Target callout
What it is. The small label next to the target.
What it shows. The scenario name and the headline: inside or outside the measured envelope.
How to use it. Read it for a one-glance result.
Example. "Inside the tested range".
What it does not do. "Inside" means it lies within the region spanned by PSI test points in this regime (between tests, not necessarily tested at that exact point); it does not mean safe.
Verdict rail
What it is. The thin coloured strip at the chart's right edge.
What it shows. The headline at your oxygen along the pressure axis.
