§ 01 · Some Things I’ve Built

Flagship · N=04

Independent builds: I chose the problem, designed the system and wrote it, and the source is open for every one.

SYS.01

Understory

Explains why a line of code exists, from the commits, pull requests, issues and reviews behind it.

The model only explains evidence collected without it: every citation is checked against the real artifacts, a claim counts as supported only when its source is quoted verbatim, and a silent history is reported as silent.

Evidence

An 8-case gold set runs the real pipeline on a seeded repo: 7/8 pass, out-of-scope questions are refused in 14/14 scored runs, and the failing case is published with its cause.

Full record

Software archaeology for a line of code. Point it at a GitHub or GitLab repository, pick a line, and it follows blame to the commits, pull requests, issues and reviews behind it, then asks a language model to explain the why using only that evidence. The model never has the last word: a deterministic check matches every citation against the artifacts actually collected, a second pass accepts a source as support only when it quotes that source verbatim and the quote is found in it, and confidence is computed from those signals rather than taken from the model. When the history does not explain a line, the case says so and marks the gap. It runs on the web with GitHub sign-in and cases saved to Postgres, from the terminal, as a VS Code extension, or as a Docker container inside a firewalled GitLab.

Horizonte

A music player where the record has mass, and the mass bends the space around it.

One full-screen fragment shader bends the typography, the cover and the dust using the same gravitational field, with nothing drawn on top.

Evidence

Each record’s physics comes from its own audio descriptors: measured offline in Python, reproduced in the browser by a hand-written FFT held to the same numbers.

A music player where the record has mass and mass bends space. A single full-screen fragment shader deforms the monumental typography, album art and dust using the same gravitational field, with nothing drawn on top. Collection, album and track exist as one continuous change of scale rather than separate screens. Each record's physics comes from its own audio descriptors, measured offline in Python and reproduced in the browser by a hand-written FFT using the exact same numbers.

Plain-language auditor for documents, measured against ABNT NBR ISO 24495‑1.

EvidenceThe fence between proof and signal is a CI step: the build fails if the deterministic core imports the model layer, and 2,500 tests pin each detector to the cases that broke it.

Full record

Deterministic text auditor that checks a document against verifiable criteria for clarity and structure, including those from ABNT NBR ISO 24495-1. Its 23 detectors flag passages that may hinder reading, trace each criterion to its source, and explain why, without altering a word of the text. When a rewrite arrives, from the author or a language model, the engine re-analyses it and separates what it can prove from what it can only signal, with the boundary between the two layers enforced by the build.

Field noteLucid: engineering applied to auditing document clarity

Skyline

Rebuilds any public web page as an isometric pixel-art city, from the page’s real structure rather than a screenshot.

EvidenceEvery layer is built over a corpus of frozen real pages, switched on and off, and 222 checks fail if it reaches outside itself: polish changes no decision, atmosphere touches only sky and light.

TypeScriptNext.jsThree.jsReact Three FiberZustandTailwind CSSparse5Puppeteer

LiveSource
Full record

Reads the real structure of a public web page and rebuilds it as an isometric pixel-art city you can walk through. The server captures the page and sends the client only structure and metrics, never HTML; the client turns each part of the page (hero, navigation, feed, index, references, footer) into a district whose land follows how much of the page it occupies and whose buildings follow what it holds, so a news front page, a documentation site and a shop produce recognisably different cities. Click any building to see the excerpt of the page it came from, or ask the city why it looks the way it does. Fetching arbitrary URLs is the riskiest thing it does, so SSRF is closed at the socket, with every redirect validated again, and real images come through an HMAC-signed proxy; sites behind a bot challenge or a login are refused, never worked around.

Origin Trace

Finds the exact Wikipedia edit that introduced a sentence and determines whether it ever had a source.

Evidence278 tests drive a fake Wikipedia instead of the live API; one caps a full descent at 20 revision reads, so the O(log n) claim breaks the build if it ever regresses.

Provenance tracer for any Wikipedia claim: with no AI and no guessing, it bisects a revision history thousands of entries long to find the exact edit that introduced a sentence — reading dozens of revisions instead of all of them — then classifies whether the claim was born with a source, had one retrofitted later, or never had one. It follows the sentence through rewordings by shared anchors, flags circular sourcing, and audits a whole article sentence by sentence into an evidence-health dossier.

Full record

Full-stack reading platform — library, feed, ratings, submissions and a moderation workflow, behind Google, GitHub and credentials auth. The recommendation rail is the part taken seriously: a pure, dependency-free module that blends a Bayesian-damped community rating with category affinity, tells the reader why each book was picked, and — holding no database — can be evaluated offline. A seeded leave-one-out harness hides a book each synthetic reader would love among distractors and reports hit-rate@4 ≈ 0.845 and MRR ≈ 0.766 over 400 trials, against a random baseline of ~0.15. The test fails below 0.8, so the number stays measured rather than remembered.

Computer Engineering and Systems Laboratory, Federal University of Ceará
Research grant · coordination

Technical lead of the ERP that took LESC’s project management as an EMBRAPII unit off spreadsheets, leading ten people across DevOps, front end, back end and QA while also writing front-end code.

  • Proposed moving the front end from Flutter to React and Next.js, which the team adopted: native HTML, DOM and CSS, easier accessibility work and direct browser APIs, and mature libraries for the forms and tables an administrative system runs on.
  • Introduced front-end testing with Vitest and Testing Library on jsdom, so components and interface behaviour are tested without running the whole application in a browser.
  • Set the team’s working conventions: Conventional Commits, a Trello template stating the minimum a task needs before it reaches development, and a link from every card to its pull request, so any request leads straight to its implementation.
  • Onboarded all four people who joined in recent months, from the project’s context and architecture to the team’s standards and workflow, staying with each until they could work more independently.
  • Built the financial simulation module for project prospecting, with an approval workflow and persisted results.
  • Moved activity reporting, review and signing into the ERP, DocuSeal replacing DocuSign since May 2026, retiring emailed PDFs and hand-set signatures that slowed payments and left reported work untraceable.

fix(checkbox): sync hidden input when initially indeterminate

Problem
A checkbox that started indeterminate exposed a plain unchecked native input.
Fix
The machine now syncs the native input on entry, as select already does.

Areas: AccessibilityState machinesForms

Investigation
Conditions
@zag-js/checkbox 1.45.0 with defaultChecked: "indeterminate" or a controlled checked: "indeterminate", in every framework adapter. The control showed the mixed state while the hidden input kept indeterminate: false until the first change, so a screen reader on that input announced “not checked” instead of “mixed”, :indeterminate did not match, and the same held after a form reset with no interaction yet. Reported by someone testing through Ark UI, which is built on Zag.
Cause
The machine wrote the native input in one place, syncInputElement, called from a watch on checked. track skips the initial value in every adapter, so the action never ran on mount, and indeterminate has no HTML attribute, so the render could not set it either: the machine state said "indeterminate" and the input said nothing. The report showed the mismatch; why it happened was not in it.
Change
Adds entry: ["syncInputElement"] to the checkbox machine, two lines, so the action that already kept the input in step with later changes also runs once on mount. That write sets the values the input already has, apart from indeterminate, and dispatches no events.
Test
An indeterminate example page in five frameworks (Next, Nuxt, Preact, Solid and Svelte) mounts an uncontrolled and a controlled checkbox; a Playwright test opens it and checks that the hidden input’s indeterminate is true and checked is false before any interaction. It fails without the change.
Decision
Syncing on entry follows the precedent select set with syncSelectElement, so the input is still written by one action rather than a second, per-adapter mount effect. The first commit also tested the controlled case, a click clearing the state, a form reset restoring it and an accessibility pass; in review the maintainer trimmed the e2e to the initial case, the one that fails without the fix, and reworded the changeset. The fix and the five example pages are from the first commit.

fix(Search): apply tabIndex to the collapsed expandable search button

Problem
A collapsed ExpandableSearch stayed in the tab order even with tabIndex={-1}.
Fix
While collapsed, the expand button now takes the consumer’s tabIndex.

Areas: AccessibilityFocus managementReact

Investigation
Conditions
Reported by the IBM Knowledge Catalog team on @carbon/react 1.117 with React 19: an ExpandableSearch given tabIndex={-1} to keep it off the keyboard path. While the search was collapsed, Tab still stopped on its magnifier; once expanded, the input honored the prop.
Cause
ExpandableSearch passes tabIndex through to Search, which applies it to the <input> only. While the search is collapsed, that input is inert with tabIndex="-1", and the one focusable element is the magnifier, a role="button" whose tabIndex was hard-coded to 0, so the prop went to the one element that could not take focus. The report had pinned the symptom to the collapsed button.
Change
One expression in Search.tsx: while collapsed and enabled, the expand button takes tabIndex ?? 0 instead of 0. The other states keep their values: no tabIndex when disabled, and -1 once expanded, where the prop keeps going to the input. A search without tabIndex behaves exactly as before.
Test
Four tests across Search and ExpandableSearch: the collapsed button carries -1, a disabled button carries no tabIndex even when one is passed, and after expanding by click the input carries the prop. The collapsed-button tests fail without the change.
Decision
Disabled takes precedence over the consumer: a disabled button gets no tabIndex even when one is passed, so tabIndex={0} cannot put a disabled control back in the tab order, and a test pins that case. The PR merged as opened, with no change in review.

perf(target-size): skip neighbors at least minOffset away before checking role

Problem
target-offset measured every neighbor in a 200px grid, even ones too far away.
Fix
An opt-in findNearbyElms margin drops far neighbors before any expensive work.

Areas: PerformanceAccessibilityGeometry

Investigation
Conditions
Any audit that runs the target-size rule (WCAG 2.5.8), which is off by default and enabled explicitly. The cost grows with how densely targets sit: on the repository’s MDN page, one run checked the role of 213,510 neighbors and called getOffset 33,279 times.
Cause
findNearbyElms(vNode, minOffset) returns every element in the 200px grid cells around the target, and target-offset ran getRoleType, isFocusable and getOffset on each of them, including neighbors far enough away that they could never be “too close”. The issue, opened by the maintainer, asked to test target-size performance and fix what turned up; this was the waste it turned up.
Change
Adds an opt-in withinMargin option to findNearbyElms that returns only elements whose bounding box overlaps the target’s box grown by the margin, skipping the rest before the dedupe and isFixedPosition; target-offset opts in with minOffset. No offset result can change: a skipped neighbor is at least minOffset away box to box, so its offset is at least minOffset / 2 and the doubled value never falls below minOffset. The one difference is deliberate: a far neighbor with too many rects used to leave the target incomplete, and it is now skipped, which is right because it cannot be too close.
Test
Six findNearbyElms tests pin the margin (same grid cell, exactly at the margin, diagonals, margin: 0) and five target-offset tests pin the distances that matter, such as an undersized neighbor 21px away that must still fail. Breaking the filter in eight ways (half the margin, a hard-coded 24, summed axes, an inclusive boundary…) made at least one test fail each time. On 5,515 nodes across the repository’s perf pages and five synthetic pages, results were identical; getOffset calls fell by 65 to 94% and the rule took 14 to 45% less time.
Decision
The first version filtered inside target-offset. In review the maintainer suggested moving the filter into findNearbyElms so other callers could use it, as an option so the public API would not break; that version also ran 2 to 5% faster. target-size stays out on purpose: it reads the same list to find content that overflows the target, and opting it in turned 186 of 300 incomplete results into violations on a test page. The maintainer reran it on separate benchmark sites and confirmed both the speedup and the unchanged results.

fix(search): preserve word boundaries between block elements

Problem
Search glued table cells together, so a cell’s first word never matched.
Fix
Text extraction adds one space between blocks and none inside inline text.

Areas: SearchMarkdownParsing

Investigation
Conditions
useSearchCollection and queryCollectionSearchSections on any page whose text sits in sibling block elements: table cells and rows, list items, paragraphs in a blockquote, the blocks inside an MDC component. The report’s table was indexed as Setting NameDescriptionapi_keyYour API…, so searching for Description, Your or Request missed the section.
Cause
The report traced it to extractTextFromAst, which joined child text with an empty string. What it left open was why nothing separated the blocks: the @nuxtjs/mdc compiler drops the newline-only text nodes between block siblings, so the tree’s structure was the only record of a boundary, and the glue reached every block structure, not only tables.
Change
Rewrites extractTextFromAst as one walk that marks a pending boundary on entering and leaving a block element and writes a single space before the next text only when neither side already has whitespace. Inline elements set no boundary, and the boundary is a flag rather than a count, so nested blocks never double the space; existing whitespace is left as it was.
Test
Ten unit tests pin the boundaries in tables, minimark bodies, nested and loose lists, blockquotes, MDC components and slots, around <br>, <hr> and ignored blocks, and pin that inline text and headings come out exactly as before. An end-to-end test parses the report’s table with the real MDC parser, indexes it into an in-memory SQLite FTS5 table and searches each cell’s first word; the old extractor fails it.
Decision
Joining children with a space would have fixed the tables and broken inline text: un**bold**ed would index as un bold ed, so the boundary follows the tree instead. The PR treated unknown and custom tags as inline; in review the maintainer inverted that rule, listing the inline tags so that everything else, raw HTML blocks such as <article> and custom components included, separates (an automated review had flagged article and figure). The maintainer also made an ignored block set its own boundary next to bare text and added img as inline. The walk, the single-space rule and the tests, one expectation aside, are from the first commit.

Fix declaration maps for export assignment expressions

Problem
TS 7 emitted no .d.ts.map mappings for export default of an expression.
Fix
Synthesized export assignments now keep the statement’s source-map range.

Areas: CompilerSource mapsGo

Investigation
Conditions
The native compiler (TypeScript 7) with declaration and declarationMap on, and an export default or export = of anything other than an identifier, such as export default { b, d }. The .d.ts was byte-identical to TypeScript 6.0’s, but its map came back with "mappings":"", so no position in it resolved to the source.
Cause
For these cases declaration emit synthesizes a declare const _default and a new export default _default;. When that logic moved into a shared transformExportAssignment (microsoft/typescript-go#3388), the export stopped being built with UpdateExportAssignment(input, …), which kept the original statement’s source-map range, and started using NewExportAssignment, which has none, so the printer had nothing to map. The report had narrowed it to the synthesized _default; the identifier form it used as the working case still mapped, but had lost its statement-level start and end mappings too.
Change
Assigns the original statement’s source-map range to each of the four export assignments transformExportAssignment synthesizes, with EmitContext().AssignSourceMapRange(exportAssignment, input): four lines in transform.go. Only the maps change; the emitted declarations do not.
Test
A new compiler test, declarationMapsExportAssignmentExpression, baselines the maps for export default of an object, export = of an object, export = class {} and a default-exported arrow function; the object case now maps exactly as TypeScript 6.0 does, and the old transformer fails it with an empty map. The existing declarationMaps baseline now matches 6.0, and no .d.ts baseline changed.
Decision
Copying the statement’s Loc onto the new node would also have restored the mappings, but it reattaches source comments: declarationEmitCastReusesTypeNode4 would emit export default /** @type {P} */ _default;. Copying only the source-map range keeps every declaration byte-identical. In review, the maintainer pointed to an automated note that the class and function branches had no map coverage; those two cases came in a second commit, and the maintainer approved with no change to the code.

fix(core): preserve semicolons in style values

Problem
mergeProps truncated style values at every ;, even inside quotes or url().
Fix
Style strings now split only on semicolons outside quotes and parentheses.

Areas: ParsingCSSFramework internals

Investigation
Conditions
Any style string passed to mergeProps in @zag-js/core 1.44.0 alongside another style, and the Svelte adapter’s own mergeProps, which returns a string. --label: "a;b" came back as "a, and a data URL such as url("data:image/svg+xml;base64,...") was cut at its first semicolon. It reproduces in Node, with no browser.
Cause
The parser read each declaration with CSS_REGEX, whose value group [^;]* stops at the first semicolon wherever it sits, so a ; inside a string or a function read as a declaration separator. The Svelte adapter carries its own copy of the same parser. The report pointed at the regex.
Change
Replaces the global regex loop with a single pass that tracks quotes, escapes and parenthesis depth and ends a declaration only at a top-level ;; the regex now reads one declaration at a time. The same scanner goes into both copies, core and Svelte.
Test
Core tests pin quoted values, an escaped quote, data URLs inside url() and a nested image-set(url(...)), with a baseline that ordinary separators still split; a Svelte test checks the adapter’s combined string. All but the baseline fail against the old regex.
Decision
In review the maintainer added /* */ comment handling to both parsers, so a ; or ( inside a comment no longer counts, with its own test, and reworded the changeset. The quote, escape and parenthesis scanning, the Svelte copy and the other tests are from the original commit.

fix(Loading): reset overlay dialog focus outline

Problem
The Loading overlay drew the browser’s focus ring around its spinner.
Fix
Resets the outline to transparent, which forced-colors mode still paints.

Areas: AccessibilityFocus managementSass

Investigation
Conditions
Loading with withOverlay, the default, in Chrome and Edge. The ring appeared on mount and again after every Tab.
Cause
The overlay’s focus trap (#22196) focuses an internal tabindex="-1" dialog on mount and reclaims it on every Tab. Carbon gave that element no focus style, so Chromium painted its user-agent :focus-visible outline.
Change
Applies Carbon’s own focus-outline('reset') to that element only. The reset is a transparent 2px outline rather than outline: none, so forced-colors mode still shows a focus indicator, as on .cds--modal-container.
Test
A Sass regression test compiles the Loading styles and asserts the exact declarations on the overlay dialog’s :focus rule. The existing focus-trap tests still pass.
Decision
The issue suggested reverting #22196. The fix keeps that focus trap, and its follow-up in #23152, and changes only how the programmatically focused element is painted.

fix(colors): publish generated type declarations

Problem
@carbon/colors 11.59.0 types pointed to a missing file; TypeScript saw no exports.
Fix
Publishes js/generated, guarded by a test that walks the declaration graph.

Areas: Package publishingTypeScriptDesign tokens

Investigation
Conditions
Any TypeScript project importing the package from 11.59.0 on, such as import { gray40 } from '@carbon/colors'. Runtime bundles kept working, so only type-checking broke.
Cause
After the DTCG migration, src/index.ts re-exports Style Dictionary output. tsc keeps that relative specifier, so the published lib/index.d.ts pointed at ../js/generated/, a directory the package’s files allowlist left out of the tarball.
Change
Adds js/generated to the files allowlist, the pattern @carbon/themes already publishes, so the re-export in lib/index.d.ts resolves inside the tarball.
Test
The test resolves every relative import reachable from types and checks it against files; it fails without the fix. Checked with npm pack --dry-run, which follows the same packlist as lerna publish where yarn pack does not, then type-checked the packed tarball under node16, nodenext and bundler resolution.
Decision
The generated declarations are wider than the hand-written ones in 11.58.0 (string instead of literal hex types) while exporting the same names. The PR flags that difference and leaves it out of scope.

fix: don't overwrite an unchanged spread value

Problem
Number inputs set through a spread erased incomplete text such as 1e while typing.
Fix
The spread path no longer rewrites a value the element already holds.

Areas: Framework internalsDOMForms

Investigation
Conditions
A number input fed through a spread whose value is read back from the input, as SvelteKit remote forms do with field.as('number'). Typing 1e, or 250. under some locales, cleared the field. A plain input, or value={...} without a spread, never did.
Cause
Incomplete input reads back as ''. That value returned through the spread, and the spread path wrote element.value unconditionally, clearing the field. The non-spread path already skipped equal writes, a guard Svelte 3 also had and Svelte 5 lost.
Change
Skips the write when element.value already equals the incoming value, as set_value does. The first write still happens: it sets the input’s dirty-value flag, without which a later defaultValue would change the field.
Test
A runtime-browser test types through document.execCommand('insertText'), so the incomplete state comes from the browser’s own editing, not from a mock or a dispatched event. It fails without the change.
Decision
In review the fixture moved from 250. to 1e: Chromium on Linux accepts 1. as 1, while 1e is incomplete on every platform. Comments documenting the guard and the execCommand choice were added at the maintainer’s request.

The six checks had no incomplete message, and nothing caught it: getCheckEvaluate, the helper that fails a test when a result has no matching message, never reached their undefined paths.
Change
Adds the six messages, covers each undefined path through getCheckEvaluate, and moves label-content-name-mismatch onto the helper so its existing messages are asserted too.
Test
New cases build SerialVirtualNodes with no parent or children and stub getComputedStyle to return a non-numeric value, so each undefined path runs through the message check. The locale template and rule docs were regenerated.
Decision
Scoped with the maintainer on the issue before writing code: the seven checks flagged in #5367 in this PR, and the migration of every remaining check test to the helper as separate follow-ups.

§ 04 · About Me

Profile

I came to engineering through architecture and design, which is why shipping a feature only counts when the system it lands in can still be understood.

My journey in technology is dedicated to transforming public services through code. As a full-stack developer at ÍRIS (Government of Ceará’s Innovation and Data Lab), I engineer end-to-end digital solutions to modernize public service delivery, from AI-powered prototypes to secure APIs.

Previously, I directed the development of the Ceará sem Fome Platform, where I built a unified design system, data management interfaces, and analytics dashboards to support food security efforts for vulnerable populations.

My path runs from the built environment to the screen. I trained as an architect and urbanist (UFC), then took a master’s in Psychology researching autism and the built environment, with a focus on universal design and sensory-inclusive spaces for people who perceive the world differently. That question didn’t change when I moved into software; it only changed medium. I build full-stack systems where accessibility and legibility are measured, auditable properties rather than afterthoughts. It is the same attention to the person on the other side, now in TypeScript, React and Laravel.
