Build a secret's link from the site's URL, not the browser's
Reported from production: clicking a secret link gave an IIS 404, and the link read /s/<token> where the site lives at /shopdb/s/<token>. The link was assembled from window.location.origin, which is scheme and host only. site_base_url already exists for this and says so in its own description - "used for QR codes and any absolute link the app emits" - with getSiteBaseUrl() as the helper the QR pages use. This reached past all of it. Both halves were wrong, and the second is worse because it fails silently: MOUNT PATH. A site served under /shopdb or /ops carries that in front of every route. Leaving it off is the reported 404. HOST. Whoever creates a secret may have reached the app by an IP, a short hostname, or a name that resolves in one VLAN, and the recipient opens the link from somewhere else entirely. The configured site URL is the one address known to work for both of them. The shape of this failure is what makes it worth spelling out: the secret was created SUCCESSFULLY and the sender was handed a link that could never work, so the failure landed on the recipient, the sender had no reason to doubt it, and the secret expired unread. A 500 would have been kinder. Falls back to the browsing origin when a site has not set site_base_url, which is what every other absolute link here does. BASE_URL is injected at build time, so the subpath half of this cannot show up in dev and only appears on a subpath deployment. |

Refuse a measurement that makes the label stop existing
Reported as a barcode rendering 176 by 0. A bar height of zero is what does it: the number went straight into a CSS length, height: 0in is perfectly valid, and an image sized height: 100% of a zero-height box is zero pixels tall. The label comes out full width with nothing on it, which reads as a rendering failure rather than as a field doing exactly what it was told. A cleared field was the same bug wearing a different hat. An emptied number input holds '', not 0, so the page emitted `NaNin`; the browser dropped the declaration and the box fell back to auto height. That one merely looked wrong instead of vanishing, which is arguably worse for finding it. Measurements now go through labelVars(), which will not emit NaN, an empty length, or a zero for anything whose zero means the box stops existing. Padding, the quiet zone and the gap still take zero, because there zero is a real answer, and offsets stay signed. It is a separate module because this is exactly the kind of arithmetic that needs tests rather than a preview: every case in labelVars.spec.js is a value a number input can actually hold. The stylesheet now carries fallbacks on its var() reads as well, but they are a net, not the fix: a custom property set to garbage is substituted and then dropped at computed value time, and the fallback does not apply - it only covers a property that is absent entirely. |

Stop a caption from eating the barcode, and put the labels beside the settings
Reported as the CODE128 not appearing in the preview. It was appearing, in 44 of the 45 preset and layout combinations swept - as a 36 pixel stub. The code box and the caption were both allowed to grow, so a caption of any length took half the label and then kept taking, and on 1.00 x 0.50in stock a few words of caption left a barcode too narrow to scan. Present, useless, and indisinguishable from a failed render. The caption now takes the room it needs and no more, and a CODE128 holds at least 40% of the label, or all of it when stacked: past that there are too few narrow bars left to read, and a caption that wraps or clips is the better trade. So that a real failure can never again look like this one, an empty code box now says so in red in the preview. It is screen-only - the marker must never reach a printed label. The settings were a narrow column with the preview trailing below them, which put the labels being adjusted off the bottom of the screen. Settings on the left, labels on the right in a column that stays in view and scrolls on its own, folding back to one column on a narrow window. That scrolling column is a print hazard worth naming: an ancestor with its own overflow clips a multi-page print to whatever happened to be on screen. Print resets it, and the check is a six-page two-sided run coming out as six pages with the label as the only clipping box in the chain. |

Put a code on the back of a card, a picture on the front, and the page in the app
The back side landed last commit carrying text by default, and a back laid out as text-only renders no code box at all. So a two-sided run came out with a blank reverse, which reads as the code having failed rather than as a setting doing exactly what it said. The back now defaults to carrying a code, takes its own content per row, and chooses its own symbology - a QR on the front that opens the record, a CODE128 on the back that the bench scanner already reads. Text-only is refused while the back carries a code, and the contradiction is reconciled on load, so a saved setting from the broken combination repairs itself rather than printing another blank box of cards. A picture can go on a label: above the code, beside it, or behind everything as a watermark, on either side or both. The file is read in the browser and never sent anywhere, which is what makes it usable at an air-gapped site, and it is deliberately not saved between visits - a data URL runs to megabytes and would take every sizing value with it when the quota gave out. The watermark says plainly that it costs the scanner contrast. The generator was a full-screen route with no navigation and a narrow column of controls against the left edge. That shape exists so a print cannot put the sidebar on label stock, which is a real hazard and the reason core's label pages are built that way - but it is a hazard the print stylesheet can answer, and style.css now hides the shell at print time. A tool someone spends ten minutes in gets the navigation and the full width; the stock still gets nothing but labels, confirmed against a print PDF rather than a preview. Two smaller things found while checking the above. A test print paired each page with a rendered code by loop position, while the codes are keyed to position in the whole run, so a two-sided test card could carry the wrong code; the index now travels with the page. And the back's dotted preview outline outspecified the print reset, drawing a dashed rule down the edge of every second card. |

Give a label its own gap, its own position, and a back side
Three things the code generator could not do, each of which had someone
working around it with a control that meant something else.
The gap between a code and its caption was the quiet zone. That is the
clear space a scanner needs around the code, so closing up a caption meant
shaving the thing that makes the code readable, and the only way to get a
tight label to scan was to push the caption further away than it looked
like it should be. Quiet zone now means the code's own margin and nothing
else; gap means the distance to the caption, and adds to the quiet zone
rather than eating into it. Each stock preset carries the gap that suits it.
Position had one pair of controls and they moved the label box on the
stock. That is the fix for a printer whose origin is off, and it is not the
fix for a code sitting in the wrong place on a label - but it was the only
lever there, so it got used for both. The label div is now the media and
holds still; everything printed sits in a content wrapper that Align,
Vertical and Content X/Y move within it. The old pair kept its behaviour
and is labelled Media X/Y.
A badge card has two sides and the generator only ever emitted one page per
card. The back can now carry the same code again, a fixed block of text,
its own per-row content, or nothing. Page order is a choice because the two
kinds of printer want opposite things: interleaved for a duplex card
printer, which takes pages two at a time, and grouped for a single-sided
one whose stack gets flipped and reloaded. A row that leaves its back
column empty still gets a blank back page - a page count that varies per
row shifts every later back onto the wrong front, which prints a box of
perfectly readable cards that are all wrong.
CSV parsing and page building moved to plugins/tools/frontend/labelPages.js

labels: one module knows how to draw a code, seven views stop guessing
Three core pages and four plugin pages each imported qrcode and jsbarcode directly, and each carried its own answer to the same questions: what margin, what width, which error correction, how big a module must be before a scanner can read it. The answers had already drifted - margin 0 in one place and 2 in another, width 150 against 160 - and on a label that is the difference between a sticker that scans and one that does not. frontend/src/utils/codes.js owns it now: the label-stock presets, the quiet-zone and margin defaults, CODE128 with no printed value, and the printer-resolution arithmetic that only the Tech Tools generator had. A view passes what is specific to its own label and nothing else - MachineBadge still asks for CODE39, because the badge readers predate the shop-floor scanners and decode nothing else, and that is exactly the kind of thing a call site should say out loud. views/print/qrLogo.js is folded in rather than left as a second half-shared helper that only some of the pages reached into. The check script now fails a build that imports either library outside that module. Without it this re-forks within a month: the next label page starts by copying the nearest existing one, which is how it happened the first time. Tests cover the part no amount of looking at a screen verifies - a QR that looks fine at 96 dpi on a monitor can be unreadable at 203 dpi on half-inch stock. |

tools: a Tech Tools section, starting with codes on label stock
A place for the small utilities a technician reaches for at a bench. The plugin owns no API and no tables: every tool runs entirely in the browser, so an air-gapped site gets them for free and a bad network cannot break them. Adding the next tool is a view, a route, and one entry in tools.js. First tool is a barcode/QR generator. Content is typed text, a URL, or a CSV (content,label,copies - quoted fields and an optional header both handled), so a batch of a few hundred is one paste. Label stock is adjustable in inches with five presets, and the code renders to an SVG data URI rather than a PNG: a bitmap gets downscaled to label size and smears the module edges a scanner reads, where SVG rasterizes at the printer's resolution with hard edges. It also carries the dot-grid rule that is easy to get wrong by eye. A thermal head cannot render a fraction of a dot, so a code sized off the grid gets uneven modules; pick a DPI and the page says what the current size lands on and what to use instead. The quiet zone is blank label rather than white baked into the code, so it can be tuned - and it applies to CODE128 too, which needs clear space at each end and was letting bars run into the caption. Tech Tools is the first bundled plugin that owns no schema, which two guards did not model: it belongs in the universal installer profile, and upgrade-all reports it 'no-migrations' where every plugin was assumed to report 'ok'. The migration test now asserts that status explicitly for schema-less plugins, so a table-owning plugin whose chain went missing still fails. |
