gui: the window rebuilt in eight steps - one scale, a grid, a live line, our own tabs and controls, Inter, a catalogue, and a list that follows the window - #103
Conversation
…it on Measured before this change: 149 distinct gaps between neighbours across the stored screens, 72 of them zero. The window had three gaps of its own and every stock container added the theme's padding on top, so what reached the screen was the sum of a step somebody chose and one nobody did. parts/tokens.go now holds the scale (4/8/12/16/24/32), the roles on it, the four text sizes, the radii and the widths - and the views name a role, never a value. Field names, screen titles and section titles are canvas texts drawn with no room of their own around the ink (parts/words.go), sentences that wrap keep the toolkit label with its inner padding taken off, and a panel keeps its inset through a layout of ours rather than the toolkit's padded container. Most common gaps on four screens after: 16, 8, 4 and 24. The guards read words through one helper, wordsOf, instead of asserting the label type in sixteen files - the first run named nine fields as nil, which is the loud kind of failure. Seven mutation entries moved with the constants they target, all still caught. Stored screens regenerated. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
A field is one row: its name in a column of names, its box beside it, and every box on a screen starting on the same edge. Until now the name stood over the box, so each field cost two rows and the small explanation button was the tallest thing on the name's line - the name floated 13 px above the middle of its box. The column is worked out from every name the window can show - the dictionary, the settings of every format, the parameters of every damage and every preset - so choosing a format with a long setting name moves no box. Names are regular weight and the one bold thing on a screen is the title of a section. The star beside a required name keeps the palette's error red, the same one a refusal uses. The count of bytes a size comes to stands right after the size box, written by core.ExactBytes, so the window and the command line spell a number one way - the window's own copy of that function is gone. The settings a format declares stand one to a row, the pairing of two narrow settings on one line is removed, and the three ways of stating a size on the batch screen keep their switch above one box in the column of controls. The table of files inside an archive keeps its name-over-box cells, which is what a table wants. Guards: a name stands level with its box to 1 px and every box on a screen shares one edge, checked row by row - the first version asked only that the name sat within the box's height and a mutation showed it passing with the name at the top of the row. A declared setting stands on the same edge as the fields above it. Every name a screen shows, at every format, damage and preset, is in the list the column is measured from - the list is written by hand, so the screens are read and the list is asked, not the other way round. Rows keep the name first and the control second, because every guard that finds a field by shape depends on that order. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The line at the foot of every form is a live summary now: how many files, how many bytes, what kinds and where, worked out from the form as it is typed, with no disk read and no planning. Until now it named the destination until the first press and never again, so after a preview a cost worked out for the old values stayed on the line while the form changed under it. A change of the form puts the summary back over whatever a press said. The arithmetic is a pure function of the targets the form settles into and says what it cannot know: a range says "between" its two ends until Preview draws the sizes, a container sized by its contents says so, and a total that leaves the range a number can hold is left unsaid rather than invented - the run is refused for it anyway. A form that does not settle falls back to naming the destination alone, read off its own box. After Preview the line is exact and the destination carries the room left on its disk, measured on the worker rather than on the interface thread. Menus and switches report a change to the runner the way boxes always did, so choosing a format from the menu reaches the live check and the line. The refusal about a run as a whole now scrolls inside the same room as the run's other messages, so the bar no longer grows when a run is refused, and the run's own words stand on the edge every other word on the form stands on. A refused preset no longer carries the note of the expansion before it. A strip of four rows in the form's grid was built first and taken out on the owner's verdict from the render: four short values in a wide strip read as a panel with nothing in it. The same four facts fit on the line the bar already keeps clear. run.go went past its ceiling and the refusal placement moved to its own file - chosen over the preview because it holds no goroutine, and the files that may be concurrent are declared by name. Guards: the line follows the boxes to the byte and follows the menu, falls back to the destination when the form does not settle, says between for a range, goes exact after a preview, and gives way to a change of the form. The guards reading the old sentences read the line instead. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The strip across the top was the toolkit's container.AppTabs, and three things about it were measured rather than disliked: its words stood on the edge of the window (x=10) while every word under them stood on the column (x=157), its renderer reserves the bar's height unconditionally so a strip drawn anywhere else would have paid for it twice, and its buttons answered the pointer only - no key could reach the way between screens. parts.Tabs draws the strip: the words go through the same column and indent as a screen's title, so the two share an edge by construction, the chosen word carries a 2 px mark in the accent colour on a hairline across the window, a word lights up under the pointer, and each word holds the keyboard - Tab reaches it, Enter and Space choose, the arrows and Home and End move along the strip without choosing. A press moves the keyboard quietly and a key moves it visibly, the decision every control here already makes. parts.Tabbed puts the strip and every screen in a plain container, so every walk that knows a container reaches every screen, shown or not, and no guard needed a new case for the strip's type. One vocabulary for a screen: its title is the word on its tab, and what the title used to say became a quiet sentence under it - rewritten to say what the screen is for, since "Generate files" under "Single batch" explained nothing. About keeps the product and its version as its title, asserted as the one exception rather than tolerated. Guards: six new in tabs_test.go (edge, title, Enter, arrows, press, hover read off the drawn colour), the stands-out guard measures the words where they are instead of at fixed bands, the Tab-order guard names the strip's words as chrome and asks that every one is reachable from every screen, and the helpers point at the new type with their 59 call sites untouched. The stored screens are regenerated, 25 of 25, because the strip is on each. Open went past the crowded band and lost its focuser to a function. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Step 5 of the window rework. The buttons, the tick-box switch and the three-ways-of-stating-a-size control are drawn by the tool now rather than by the toolkit, so the states the toolkit drew wrong or not at all - a focus ring the filled button swallowed (O207), a hover nobody could see (O205), a pressed look that did not exist, Enter that did nothing - are ours to draw. - parts.Button: four looks (primary, secondary, quiet, glyph) and five states. A filled face for the action that does the work, an outline for the rest, hover and pressed washes worked out from the palette, and a 2 px accent ring drawn only when a key put the focus here. Enter presses as well as Space. - parts.Toggle: our own square, its name in the column of names like every field rather than on the control. The other side of O72, in a grid. - parts.Segments: one control with the arrows walking the choice, in place of three radio circles - one keyboard stop, not three. - The same ring on every stop: a box, a menu, a switch, the segmented switch, a button. Entry wires it on focus; WithRing leaves a self-edged control alone. - O213: one quiet colour. A caption, the byte count and a folded summary recede to the hint's grey; the disabled colour is kept for a switched-off value only. The look of each state is held by the 25 stored screens, regenerated here. Six guards for the behaviour a picture cannot show, each with a mutation.

…ed ourselves The window was drawn in Noto Sans, the toolkit's own face - the one thing left on screen after steps 1 to 5 of the rework that still said "library". Inter 4.1, the static Regular and Bold instances, is embedded by internal/gui/font under the Open Font License, read from the release and from the name table of each file. Every other style falls through to the toolkit's face, in the order the default theme resolves them. The window binary grows by 816 279 bytes, measured on a build. That entry is the first in the licence registry for bytes a package of this project embeds itself, and the registry could not describe it: what a binary carries was decided by module, and both binaries are one module. The embedded-files guard and the SBOM generator skipped our module altogether. Now an entry of ours is answered by package - go list for the document, the package's own init (legal.Carrying) for a running binary - and the guard walks our module like any other: a file there is either in the registry or named as our own work. The toolkit's Inter symbols file is renamed Inter Symbols, so the two entries cannot share a name. Guards: the painter measures a sentence wider under our theme than under the toolkit's, for both weights, and the styles the window never draws keep the toolkit's face. The command line links no package of ours that embeds somebody else's bytes and its licence command names none, and every such package announces itself. Stored screens regenerated - the widget trees change only in positions and sizes. A set of outlined Lucide icons was built and rendered in the same step and dropped after a look at the render, so nothing of it is in the tree. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
tfg-gui --catalogue opens a hidden screen that draws each part of the window in each state it has, from one registry (internal/gui/catalogue): sixteen entries, ninety-three states, the same widths as on a form. The first catalogue was a probe outside the repository and stopped compiling two steps ago without anything saying so - a catalogue nothing builds is a catalogue that does not exist. The registry is held to the package it draws: go/ast reads every exported type, constructor and drawable function of parts, and each has to be an entry, a state of one, or named with the reason it is left out. Every state has to draw differently from the others of its entry - that guard found a fold built open, a hover on the chosen segment and two identical disabled faces before anybody looked at a picture. The whole catalogue is a stored scene, drawn at its full height, so a change of a token shows on every control at once. A build with no window answers the flag with the same sentence and exit code as before. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The list a menu drops down stopped at eight rows in every window: measured with guirender, 224 px at 800x600, at 1100x1300 and at 1101x1025 alike, so a third of the twenty-four formats showed however tall the window was, and every format added would have lowered that share. Eight was chosen for the smallest window and then applied to every window - a rule about the label and the context staying in view, written down as a count. The ceiling is a share of the window now: half of its height, in whole rows (listShare, parts.ListCeiling), applied where the window's height is known - roomForList, which already chose the side a list opens on and cut it to the room there. Ten rows at 600 px, where the list still ends above the buttons, eighteen at 1025, twenty-three at 1300. The list itself no longer carries a ceiling, because it does not know the window. The guard asks two canvases, one half the height of the other: on each the list covers no more than half and no less than half less a row, in whole rows, and it shows more rows on the taller one - a count small enough to fit inside the share is green on one canvas and red on two. The catalogue's list states are drawn as wide as the box they would drop from, where a bare list measured its width off an empty template row and stood as a 42 px strip with one letter of each value showing. Three semicolons left in comments by the previous step are full stops. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Two steps of the window rework landed without an entry under Unreleased: the window being set in Inter, which a person sees and which makes the window binary about 800 kB larger, and tfg-gui --catalogue, which is the first argument the window binary has ever read. Both are things somebody updating would want to be told. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…n table The rows REGRESSION.md carries for steps 3 to 7 of the window rework named their guards by test and left the file in the paragraph over the table, which the table guard does not read - so five files cited in CLAUDE.md counted as unjustified, and the guard was red from the step that added the first of them. The rows name their files now, one of them being the file this list excused, and a name excused after it is justified is the drift the list says it will not hide. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…again The full mutation run at the end of the window rework reported nine entries not caught. Not one was a defect in what the tool does - each was a guard, or its mutation, that had stopped reaching the thing it names, and the run is the only instrument that sees that shape. Three came with the rework. The line the "explanation loses its button" entry broke lived in withDetail, which nothing had called since the form became a grid - the function is gone and the entry aims at the name cell that adds the button. The "back to the overlay layer" entry named a package detail.go stopped importing when DetailButton moved onto our own Button, so its mutant could not compile - it goes through the canvas's overlay stack now. And the refusal-width guard read the generate screen, which has had one field to a row since the grid, so nothing it measured went through Fields.Row - it asks the batch screen now, where the files inside an archive still stand three to a row, and a message confined to its cell is 185 px where the row is 788. Six were older, found now because the rework was the first full run in a while. The section-name guard classified a field as bold words at the body size, which no field name has been since the grid, so its set of fields was empty on every screen - names are read off the rows now, and a screen with sections and no fields is skipped rather than counted as clean. The progress bar guard wrote 64 MB in eight files, which has taken 40 ms since files are written over several threads - under the 100 ms before the bar first draws - so it writes 2000 small files, whose cost no faster disk removes. The manifest guard for verify asked the exit code, and an unclaimed manifest has been "another run's record" since 2026-09-07, a note at exit zero - it reads the JSON report and demands no difference of any kind. The temporary-name guard could not tell the check before the run from the single door every file is created through, since both leave the file whole and the exit code non-zero - it takes the second file's name now and demands that nothing was written at all. The golden-value entry turned one of md's three cases into txt, which left md pinned by the other two - it aims at pdf, which has one. And the plan-ceiling guard planned four thousand files, which is fewer than the 4096 the ceiling waits after a swept reading that finds the heap no larger than at the start - it plans ten thousand, so the second reading lands on a plan that nothing can collect.

The exhaustive linter, which runs on the CI runner and not in the subset the rework was verified with step by step, found two switches from the rework with cases left unsaid: the primary button's face on a resting or disabled button, and the strip's total when every size is on the form. Both fell through to the right answer and now say so. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Keep catalogue size separate from the ordinary window size.
When showCatalogue is true, run still reads host.Remembered().Size() and registers host.rememberThisSize(). Closing a resized catalogue therefore overwrites the windowWidth and windowHeight values used by the ordinary GUI.
Use the existing default size for catalogue mode and register the close callback only for the ordinary GUI.
size, centre := window.HowToOpen(fyne.Size{})
if !showCatalogue {
size, centre = window.HowToOpen(host.Remembered().Size())
}
w.Resize(size)
if centre {
w.CenterOnScreen()
}

w.SetOnClosed(func() { host.rememberThisSize() })

The desktop driver delivers a press of space to a focused control twice - as the key, ending in TypedKey, and as the character, ending in TypedRune (internal/driver/glfw/window.go, processKeyPressed and processCharInput, read in the pinned module). The toolkit's own button leaves TypedRune empty for that reason. Ours answered both since the controls became ours, on the sentence that the toolkit's button "answers to space" - true of its TypedKey and not of that hook - so one press of space on Add batch added two batches in the window. No guard saw it: the test driver delivers a key and a character as two separate calls, and every guard sent one. An outside review of the pull request named it. The finding was checked against the driver's source rather than taken from the review, and holds. TypedRune answers nothing now, and a guard delivers one press the way the driver does - both calls - and asks for one press. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…no key Four findings of an outside review of the pull request, each checked against the toolkit's source before anything was changed, and one more found beside them. A press on a switch - the square and the segmented one - now puts the keyboard on it quietly, and the first key drawn on it turns the ring on: the rule PointerFocus has stated since the menus, which the Chooser followed and the two controls of the rework did not. The desktop driver unfocuses whatever had the keyboard on a press and leaves focusing to the widget (internal/driver/glfw/window.go, mouseClicked); the toolkit's own Check and radio item focus themselves in Tapped, and ours did not, so after a click the keyboard was nowhere - the next Space flipped nothing and the next Tab started from the top of the screen. The review said the keyboard stayed on the previous control, which the driver does not do, and drew the right conclusion from the wrong mechanism. The guard that promised "a press moves the keyboard without drawing its mark" asked only about the mark, so a control that took the keyboard nowhere passed it. It asks both now. A frozen control answers no key. The focus manager asks Disabled only when it moves the focus, and the driver hands every key to whatever is focused, so a segmented switch that had the keyboard when a run began went on moving its choice under a form drawn as frozen. The review named the switch. The menu does the same through the toolkit's Select.TypedKey, which asks nothing either, and is stopped in the same place. One press of the space bar flips a switch once. Toggle.TypedRune answered the space character as Button.TypedRune did, so a press flipped the switch twice and left it where it was, which reads as a switch that ignores space. Found by reading the control beside the one the review named. An ownWork exemption that no build spends is red, as a registry entry that no build matches already was: a key for a file that has gone would exempt whatever landed at that path next. The catalogue no longer writes its window size down as the size the ordinary window opens at. The comment beside it said nothing about it was remembered, and the close callback two lines below remembered it. Behind cgo, like the rest of the remembering, so no guard reaches it.

…ed beside it on Windows (#109) * gui: the OpenGL binding is carried as a copy that imports no opengl32.dll at load time The published github.com/go-gl/gl links -lopengl32 and calls wglGetProcAddress as an imported symbol, so the window binary names opengl32.dll in its import table and the loader maps the system's copy before a line of our code runs. Windows hands a library already mapped under a name to every later request for that name, which means a software renderer loaded by path afterwards can never be the opengl32.dll the toolkit finds when it creates its context. Measured on 2026-09-17 with the process's own module list, on a machine with a driver and on a guest with none. go.mod now replaces the module with a copy under third_party/go-gl-gl, reduced to the two packages the window imports, with one change: the Windows branch of GlowGetProcAddress looks wglGetProcAddress up at run time after loading the library by name, and both cgo LDFLAGS lines naming opengl32 are gone. PATCH.md beside the copy says what changed and why, and carries the published version's module sum, because go.sum stops carrying the sum of a replaced module. The CI module list is unchanged - go list reports a replaced module under its own path - and the comment above it says so. Three guards. One downloads the pinned version and holds every file of the copy to the published bytes plus exactly the patch, and the sum in PATCH.md to the sum the toolchain computes. One builds the window binary with cgo on Windows and reads its import table through debug/pe - no opengl32.dll, with gdi32.dll as the canary that the table was read. That one is proven by a probe rather than a mutation entry: broken by hand it went red naming the import, resolved through the -lopengl32 the windowing library links, and the run took 3 min 56 s of recompiling everything above the binding, which the mutation runner's ceiling would cap. Measured before the guard was written and worth stating: a guard reading linker flags would have refused a binary that was already right, because the windowing library links -lopengl32 too and the binary still imports nothing from it. The third guard asks that the walk behind fourteen shape guards leaves a nested module alone, which it now does by the toolchain's own rule - a directory with its own go.mod is outside "./..." - rather than by a name on a list. The registry entry for the module gains a note and THIRD-PARTY-NOTICES.md a paragraph, since the copy is what ships. The blank line that had split the window's module table in two since #103 is closed. sortedKeys in the telemetry guard sorts, which its name has promised since it was written. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * gui: a window the driver refused is tried again with the software renderer shipped beside it On a machine whose graphics driver offers no OpenGL 2.1 the window binary refused, since #108, with a sentence and exit code 1. It now tries once more before refusing: the first process starts this program again with the same arguments plus --software-gl, waits, and answers with that process's exit code. The second process, before the toolkit exists, names the driver in its environment and loads Mesa's llvmpipe from opengl/ beside the executable - renderer first, loader second, both by absolute path - so the toolkit's request for OpenGL by name finds it already mapped. Measured on 2026-09-17 on a machine with a driver: started with the flag and no variable in the environment, the window is drawn by the two files beside it and nothing else answers to that name, twice out of twice. Without the files beside it the window opens on the driver and says which file was missing. Without the flag nothing changes. The seam gains the second attempt: OpenOrRefuse asks for one when the window has no native window, and refuses with the reason only when there was none. The decision lives in gui.SecondAttempt with every piece that touches the world as a field, so a guard presses all nine states without a window, a renderer or a process: the second process never starts a third, nothing is tried where nothing ships, the arguments are handed on whole, and the refusal says what became of the renderer - which file is missing, that starting again failed, or that it was tried and did not help. On Linux and macOS it says nothing, by the owner's decision, since nothing ships there. Said out loud, rule 6: the first process writes one line before it starts the second, the second says what it draws with, and the About screen carries the same sentence for as long as the window is open. The Host gains SoftwareRendering for that, and a guard reads the screen both ways. The flag is public and takes the renderer on any machine. The first process hands the driver variable over as well, and the second sets it for itself, because a person asking by hand has no first process. Two guards learn the new file shapes with their reasons: the hardening guard, for a load by a path under the executable's own directory, and the telemetry guard, for the one spawn in this tree - this program, by the path os.Executable answers. That guard also gains os in its list of low level packages: os.StartProcess walked past it until now, found by asking what else the tree could have used. The canary carries the case, and a staleness half now covers the two file keyed registries. Its findings name the file. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * legal: the registry gains a third class, for what ships beside a binary rather than in it A module is reported by the build and a font by the compiler that embeds it. The software renderer in the Windows archive is neither: two files the release workflow downloads and puts next to tfg-gui.exe, loaded at run time, which nothing in a binary can report. So the registry gains a Companion: what it is, which binary and which archive carry it, the files in the order the program loads them with their sizes and sums, the licence expression of everything compiled into them, and exactly where the bytes come from - the project, its release, the archive and that archive's sum. Everything in the entry was read from the files of the pinned versions. The archive itself carries no licence file - one readme pointing at a web page - so docs/license.rst and licenses/ of mesa-26.2.0.tar.xz, the build list of pal1000/mesa-dist-win at its 26.2.0 tag, llvm/LICENSE.TXT at llvmorg-22.1.8 and the DirectX-Headers licence at v1.619.5 were read instead, and the renderer's own bytes were asked what they hold: Mesa 26.2.0, LLVM 22.1.8, the llvmpipe, d3d12, zink and softpipe drivers, and no zlib or zstd, whatever stands in the build environment. The GPL marked files in the Mesa tree are Linux kernel headers and two drivers' headers, none compiled on Windows. The expression is MIT AND Apache-2.0 WITH LLVM-exception AND BSL-1.0. Four consumers. The notices gain a section naming the files, their sums, the archive and its sum, and reproduce the two licence texts they did not carry - the LLVM exception and the Boost licence - from the files they came from. The window's About screen names it under a third heading, on every system, because the notices say the same everywhere; the stored picture of that screen is regenerated, one of twenty-six. The command line's list never names it, since nothing ships beside that binary. The bill of materials ships it beside the window as DEPENDS_ON, with the archive's name and sum, and beside nothing else. One guard for each consumer, and one holding the registry's file list to gui.SoftwareFiles - the same files in the same order, or the archive would be packed with something other than what the program looks for. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * ci: the release puts the software renderer beside the window, signs it, and checks it on the page Two files of Mesa's llvmpipe reach the Windows archive of the window through a download the workflow makes. The release of pal1000/mesa-dist-win to take them from, the SHA-256 of that release's archive and the two files with their own sums stand in .github/mesa-dist-win, and nowhere else the workflow can read. .github/scripts/fetch_software_renderer.sh reads that file, downloads the archive from the project's own releases, checks its sum BEFORE unpacking anything, takes exactly the two files out of x64/, checks each file's sum, and refuses anything but two files under opengl/. Run on this machine: 18 s, every sum agreeing with the registry. Run with a wrong archive sum and with a wrong file sum: refused, exit 1, nothing unpacked in the first case. Both workflows that build the window call it, on Windows only, between the build and the packing - the one that builds from a branch as well, by the owner's decision, so a build from a branch is the build a guest without a driver can be handed. The signing script used to put a subdirectory back EMPTY. It repacked from os.listdir, which names a directory and none of its contents, and zipfile writes a directory entry for a directory and nothing more - measured on an archive shaped like the window's: opengl/ came out with nothing under it, a valid archive, no error. Nothing shipped in a subdirectory until now, so nothing had noticed. It walks every directory now, counts the repacked files against what it unpacked, and signs the libraries beside the program as well as the program, verifying each one's certificate against the pin. The workflow that checks a published release reads the renderer's files out of the registry, asks the window's Windows archive to carry them, and asks every program and every library in every Windows archive who signed it - on the bytes a person downloads. The release notes say the renderer is in the archive, where, and when it is used. Six guards: the pin agrees with the registry, the fetch script checks before it unpacks and carries no copy of the pin, every window build fetches between building and packing, the signing repacks whole and signs the libraries, and the published archive is checked for the renderer. The guard over links leaving this project learns that a workflow's download from somebody else's release is not a place a person is sent. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * git: a Python bytecode cache reached a commit, and none may again The signing script was imported by a probe to exercise its repack, which left a cache file beside it that the next commit swept up. Removed, and __pycache__ ignored from here on. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * guard: the window build's fetch of the renderer is asked for as a call, not as text anywhere in the file The mutation runner answered the first version with the call commented out: the text was still in the file, the guard was green, and the archive would have shipped without the renderer. It asks for the call at the start of a line now. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs: the readme, the changelog and the security policy say the Windows window carries a software renderer One paragraph each. The readme says what the folder next to the program is, when the window uses it, what happens without it, and that nothing of the kind ships for Linux or macOS. The changelog entry says the same for a person deciding whether to update, with the version of Mesa and the fact that both files are signed, named in the notices with the sums they were reviewed at, and in the bill of materials. The security policy names the one thing in the Windows archive this project did not write, how the release workflow pins and checks it, and that the program loads it only by absolute path under its own directory and only after the driver refused. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * gui: the flag on a system the renderer does not ship for says so, rather than naming the system as an error Found in the review before the pull request: --software-gl on Linux or macOS printed "could not be loaded: linux", the reason type's words in a sentence meant for a file that did not load, and if the driver then refused the refusal would have added that sentence too - on the systems where the owner decided nothing is said about the renderer. A window asked for the renderer now says one of three things about the loading, through one function: that it draws with the renderer, that none ships for this system, or what stood in the way. The refusal on such a system stays as it was. The download address in the registry is registered with the guard over addresses in shipped code: the release workflow fetches from it and the bill of materials names it, the program never does. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * ci: the dependency gate is told about the copy of the OpenGL binding GitHub's dependency graph reported the directory behind go.mod's replace directive as an added dependency with no licence, and the gate blocked - correctly, for a name nobody had looked at. This one has been: the licence is the copied module's own MIT, carried in the directory, and the bytes are the published module plus one patch, which a guard holds by downloading the pinned version and comparing. The exception names that one directory. A second directory nobody looked at still blocks, and the guard over the gate asks both. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * gui: three things the first CI run found that no local subset reads staticcheck on Linux called loadFailed unused, because the one file that raises it is built on Windows alone - the type now lives in that file. gosec and semgrep both flagged the one spawn in this tree, a command built from variables. It is settled where they read it, with the reason: the program is os.Executable and the arguments are this process's own plus one flag. The guard on flag spelling below the surfaces found the flag's name in the registry's note, which names it in words now. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * gui: eleven things an outside review of the pull request named, each measured before it was changed The signing script interpolated a file's path into PowerShell text, and a name with a quote in it ran as PowerShell - measured before the change on a copy named "a'; throw 'injected'; #.dll": the throw ran. The path goes through an environment variable now, and a guard refuses the old shape. A file of the renderer that cannot be read was reported as missing, with the advice for a missing file. The look beside the program tells the two apart now, the refusal has a sentence for each, and the look is a function with the question to the file system handed in, so a guard can answer it with a permission error no test can arrange on every disk the same way. Two allowances forgave more than they were written for: the hardening guard let a registered file grow any number of computed loads, and the telemetry guard dropped every spawn and every computed load in a registered file. Each forgives one now, a second is a finding, and a canary holds it. The link guard's exemption for a release download applied to every file, SECURITY.md included - it belongs to the fetch script alone now, and a canary puts the same address into a human facing file and asks for the refusal. The release guards read active lines, with comments taken out, so an operation commented out is an operation gone. The walk behind the shape guards names the nested modules it skipped and the guard asks for exactly one. Guards over tracked files fail rather than skip when the file is missing - the notices, the workflows, the signing script. Three sentences said more than was true: the flag on a system nothing ships for claimed the window was drawn by the driver before the window was shown, and the readme, the changelog, the security policy and the release notes said the renderer was never touched on a machine with a driver, which the flag makes untrue. Each says now exactly what happens. Not changed, with the reason written down: the gles2 package of the binding is not patched, because no shipped binary links it - measured with go list on every release platform - and wrapping the restart's errors in English would put words a person reads outside the text package, which a guard refuses, while the sentence that shows them already says what failed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * gui: six things the second outside review of the pull request named, each measured before it was changed The release notes, the changelog and the bill of materials said the software renderer is used when the graphics driver offers no OpenGL 2.1. The program tests something else - whether the first attempt left a window - and the notes now say that, with the driver as the usual reason. The guard over links to other projects forgave a release download by the script's NAME, and any project's download in that script. The review asked for the pinned address written into the guard, which the script does not hold: it builds the address from the pin. The exemption is now the script's path from the repository root plus the project the companion registry names, so a companion added later is covered on the day it arrives. The guards over sign_release.py read text, so a required operation inside a docstring or a string literal satisfied them - and one of the texts, codesign.go, stands in the script four times, once as the constant and three times in messages. The review asked for a reader that drops every string literal, which would have turned the guards red on the correct script: five of the ten things they look for are string contents by nature, measured with Python's own tokenizer. The reader now drops comments to the end of a line and docstrings whole, keeps short literals, and what is code is asked for as a statement at the start of a line. Two allowances - a computed library load, a spawn - forgave one operation of a KIND in a registered file. They now name the operation: the call, and the function that answers its first argument, followed back to its one binding in the enclosing function. The hardening guard reads the same registry instead of a copy. The helpers and their canary have a file of their own, because the telemetry guard had grown into the band the test shape ceiling watches.
