User-facing copy + brand updates landed together:
- Page H1 + browser-tab title: "DataTools — Data Cleaning Mastery"
→ "UNALOGIX DataTools". Same change in es.json (was "DataTools —
Maestría en limpieza de datos").
- Hero subtitle: long descriptive caption replaced with the tagline
"Clean. Normalize. Transform." (es: "Limpia. Normaliza.
Transforma.").
- Sidebar brand block: wordmark is now two lines — UNALOGIX in tiny
uppercase tracked eyebrow style on top, DataTools in the 15px
semibold wordmark beneath. The 28px "D" chip stays as the
recognizable mark. New ``.dt-brand-eyebrow`` rule in
``_DESIGN_TOKENS_CSS``.
Top-right Streamlit chrome cleanup — the user reported two stacked
icon buttons. ``.streamlit/config.toml`` bumped to
``toolbarMode = "viewer"`` (most aggressive — suppresses status
indicator + deploy button + running glyph). CSS belt-and-suspenders
hides ``stToolbar``, ``stToolbarActions``, ``stStatusWidget``,
``stDecoration`` for newer Streamlit releases that keep emitting
these with inline styles even under toolbarMode=viewer.

Batch of UX tweaks the user asked for in quick succession:
- Sidebar brand block (mockup §brand) — 28px ink chip with a "D"
wordmark plus the "DataTools" text — injected into
``stSidebarHeader`` by a small JS bundled into the iframe-mounted
script that already runs from ``hide_streamlit_chrome``. The
Streamlit ``stLogoSpacer`` is hidden when the brand block is
present so it sits flush at the top of the sidebar.
- Findings cards are now collapsible. Each file's card head carries
``data-dt-collapsed="true"`` on first render; clicking the head
flips the attribute via the new ``_WIRE_COLLAPSIBLE_FINDINGS_JS``
(MutationObserver re-wires after reruns). A CSS rule
``[stElementContainer]:has(.dt-finding-group-head[data-dt-collapsed
="true"]) ~ *`` hides every later sibling of the head's element
container — covers both ``stLayoutWrapper`` (the columns rows in
this Streamlit release) and ``stElementContainer`` so the rule
survives future Streamlit layout renames. A chevron icon
(``chevron_right``) rotates 90° when expanded. The head itself
gets ``cursor: pointer`` + an accent-fill hover.
- Tool-link buttons in finding rows dropped the leading ``Open`` —
now read ``Clean Text →``, ``Standardize Formats →`` etc.
- Finding-row column order: action is now LEFT of the description,
matching user feedback (``[icon] [Tool →] [description + meta]``).
- Head padding bumped to ``16px 22px`` so the filename has visible
breathing room from the card's left edge (previously the mono
filename felt like it was bleeding into the rounded corner).
- Head margin-bottom bumped to 1.5rem for breathing room before the
first finding row when expanded; collapsed state tucks the head
flush against the card bottom with full ``--r-lg`` corner radius
and no visible bottom border.
- Files card row layout: ``✕`` button moved to the LEFT of the
filename (``[✕] [chip + filename] [size]``).
- Sidebar nav rows tightened: link padding 7px → 4px, line-height
1.25, 1px margin-bottom per li, section-header padding-top reduced.
Plus a new ``--gap: 0.25rem`` rule for vertical blocks inside
bordered containers so the Files card and findings card body have
denser inter-row spacing.
- Sidebar Language selector restyled: widget labels render as the
spec's "Eyebrow" row (11.5px / 500 / 0.08em uppercase, tertiary
ink), selectbox combobox gets a paper surface + soft border that
matches the rest of the sidebar chrome.

(3) Disabled primary buttons no longer read as a "whited-out" dark
slab. Streamlit's primary-button selector
``button[data-testid="stBaseButton-primary"]`` has the same
specificity as our previous ``button:disabled`` selector, so the
primary background + cream text kept winning the cascade tie-break.
The disabled rule's selector list now explicitly matches both the
``kind="primary"``/``kind="secondary"`` shapes AND the
``stBaseButton-primary``/``-secondary`` testids, so disabled
buttons collapse to ``surface-hover`` background, ``ink-tertiary``
label, soft border — same look regardless of starting kind. A
follow-up rule re-asserts ``color: var(--ink-tertiary)`` on every
descendant of the disabled primary so the inner
``stMarkdownContainer > p`` doesn't keep the cream label from the
"all descendants get --bg" primary rule.
(4) The sticky-footer Help + Close buttons now match the sidebar
nav-item look. Old outlined-pill chrome is gone:
``.datatools-footer-btn`` is now display:inline-flex with a
Material-Symbols ligature icon + label, borderless, ``ink-secondary``
text on a transparent surface, ``rgba(0,0,0,0.04)`` hover background.
The Close button keeps a danger tint via ``.close`` so it still reads
as the shut-down action, with a soft ``--danger-fill`` hover. Help
uses the ``help_outline`` icon, Close uses ``power_settings_new``.
Built via a small ``makeFooterBtn`` helper in the iframe JS that
appends the icon span + label text node to the button — keeps the
existing soft-nav click handlers intact.

Two visual cleanups:
1. The block-container "claim padding" rule was a no-op — it targets
the legacy ``stAppViewBlockContainer`` testid; Streamlit renamed
it to ``stMainBlockContainer`` in the current release. Updated the
selector list to match both, so the page title now sits close to
the top edge again (~0.5rem from the hidden header) instead of
inheriting Streamlit's default ~6rem header reservation.
2. ``.dt-finding-group-head`` margin tightened to ``margin: -1rem
-1rem 0.75rem``: -1rem on top/sides still bleeds the head to the
card edges, but +0.75rem on the bottom is breathing room between
the head's bottom border and the first finding row, which were
abutting before.

Mockup §file-add lands as the canonical import affordance:
- Streamlit's ``st.file_uploader`` widget is still mounted (only path
that actually receives browser file events), but parked off-screen
via a new ``[data-testid="stFileUploader"] { position:absolute;
left:-10000px; … pointer-events:none }`` rule. Its hidden
``<input type="file">`` stays reachable to JavaScript.
- The Files card is now always rendered (header + bordered body).
The bottom row of the card is a ``button.dt-file-add`` styled per
mockup §file-add: dashed top border bleeding to the card edges,
surface-hover background, ``+ Add more files`` text in
``--ink-secondary``, accent-fill on hover.
- A small ``<script>`` shipped through ``st.iframe`` wires the
button: ``click → input.click()`` on the off-screen
``stFileUploaderDropzoneInput``. Streamlit's HTML sanitizer
strips inline ``onclick`` from ``unsafe_allow_html`` content, so
the binding has to come from a real script element — same pattern
the sticky footer and Upload→Import rewriter use. A
``MutationObserver`` re-wires the button when Streamlit remounts
it across reruns. The ``dataset.dtWired`` guard prevents double
binding.
Section structure also tightened to match the mockup:
- Section heading is now ``<h2>Files</h2>`` (was ``### Import one
or more files to start``) with the count + total size on the
right of the same flex row. When no files: ``No files imported
yet``. When files exist: ``1 file · 4.8 KB total``.
- Dropped the ``upload.intro_multi`` caption and the
``upload.empty_state`` info banner — the card itself plus the
in-card Add button cover both prompts.
- Empty state now ends after the Files card (no stats / no action
bar / no findings rendered) — matches mockup's single-section
empty view.

Closes the remaining gaps between the live home page and the
``datatools_layout_redesign2.html`` mockup. Four pieces land
together because they all consume the same new CSS scaffold:
1. Page header (§page-header)
``st.title`` + ``st.caption`` + ``st.divider`` collapse into one
flex header: h1 + body subtitle on the left, ``Runs 100% locally``
privacy pill (success-fill + lock SVG) on the right, soft border
below. The "Runs 100% locally" phrase moved out of
``home.caption`` into the new ``home.privacy_pill`` i18n key
(en + es).
2. Files card (§files-card)
The "Imported files" list is now a single bordered card with a
section head (count + KB total on the right, mockup §section-head).
Each row renders a 28px accent-fill chip carrying the inline
document SVG, a mono filename, a right-aligned mono size, and a
compact ``✕`` button. The word-button ``Remove`` is gone —
replaced by an icon-only tertiary button styled via a new CSS
rule that goes transparent → danger-fill on hover (mockup
§file-remove).
3. Action bar (§action-bar)
Three buttons in one row: ``Run analysis`` (primary ink), a new
disabled ``Export report`` (secondary; coming soon, tooltip), and
``Clear results``. New i18n key ``upload.export_report``.
4. Findings — per-file group cards (§finding-group)
``render_findings_panel`` rewritten end-to-end. Output is now:
• A head row (``dt-finding-group-head``) bleeding to the card
edges: worst-severity dot · mono filename · count pills
enumerating non-zero severities (e.g. ``2 info`` blue,
``1 warning`` amber, ``1 error`` rose).
• A flat list of finding rows sorted error → warn → info.
Each row: tinted Material-icon chip + title (description
with optional ``<code>`` column chip) + mono meta line
(rows affected, samples captured) + tertiary
``Open <Tool> →`` action button that ``st.switch_page``s
to the relevant tool.
The previous tool-grouped expander stack is dropped — the new
layout is denser and matches the mockup's single-card-per-file
structure.
``_render_one_finding`` (the old per-finding helper that emitted
markdown lines + sample tables) remains in the file but is no
longer called from the home flow; left in place for any other
surface that still depends on the markdown style.
The "no issues" success state renders a green dot + mono
filename + ``no issues`` success pill in the same card chrome,
so empty-result files visually match the rest of the panel
rather than getting a generic ``st.success`` callout.
CSS additions (``_DESIGN_TOKENS_CSS``):
``.dt-page-header / .dt-page-subtitle / .dt-privacy-pill``
``.dt-files-section-head / .dt-section-meta``
``.dt-file-row / .dt-file-icon-chip / .dt-file-name / .dt-file-size``
``.dt-finding-group-head / .dt-severity-dot{.warn,.info,.error,.success}``
``.dt-group-filename / .dt-group-counts``
``.dt-count-pill{.warn,.info,.error,.success}``
``.dt-finding-row / .dt-finding-icon{.warn,.info,.error}``
``.dt-finding-title / .dt-finding-meta``
Tertiary button rule (transparent → danger-fill on hover) for
the X button and the ``Open Tool →`` row action.
theme.py:
Explicitly loads Material Symbols Outlined alongside Geist —
the severity-chip ligatures (``info`` / ``warning`` / ``error``)
need the font present even when no ``:material/`` token has been
emitted yet on the page. Tightened ``.dt-finding-icon .dt-mui``
selector with ``[data-testid="stMarkdownContainer"]``-scoped
variant so the Material font wins over theme.py's base
``var(--font-sans) !important`` on markdown descendants.
Leading section-heading emojis stripped from i18n
(``upload.heading``) for parity with the mockup's clean ``Files``
/ ``Findings`` h2s.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two pieces of the mockup 2 layout that hadn't landed yet:
1. Sidebar nav icons — emoji glyphs (🧹✂️🔍 …) swapped for
Streamlit's ``:material/<name>:`` syntax, picking the outline
Material Symbol that best matches each mockup SVG:
Home → :material/home:
Fix Missing Values → :material/help_outline:
Find Unusual Vals → :material/insights:
Clean Text → :material/text_format:
Standardize Fmts → :material/format_list_bulleted:
Find Duplicates → :material/search:
Quality Check → :material/check_circle:
Map Columns → :material/view_column:
Combine Files → :material/account_tree:
Auto Workflows → :material/auto_awesome:
Activate → :material/key:
Close → :material/close:
Streamlit injects the icon name as a literal ligature inside a
first-child ``<span>`` of the nav anchor, expected to render
through the Material Symbols font. theme.py's base rule was
forcing Geist on every span under ``stSidebarNav``, turning the
ligatures back into plain text labels — added a structural
exception that targets ``[data-testid="stSidebarNavLink"] >
span:first-child`` (and any descendant), restoring the Material
font family, neutralizing the inherited ``ss01/cv01/cv11``
feature settings, and sizing to 18px.
Also stripped the leading emojis from every page title in the
en/es i18n packs (``home.title``, ``close_page.title``,
``activation.title``, ``tools.*.page_title``) — the icons live
in the sidebar now, the page H1 no longer needs to carry one.
2. Stats overview on home — new ``_render_stats_overview`` in
_home.py emits a 4-card grid above the per-file findings panels:
Files analyzed, Total findings, Warnings (severity ``warn`` ∪
``error``), Info (severity ``info``). Card layout follows the
mockup §stats verbatim — Geist 28px / 600 / -0.03em for the
numeric value (the "Display number" row in spec §4), tiny
uppercase tracked label, paper-surface card with the standard
warm border + faint shadow. The Warnings / Info cards tint the
number with ``--warn`` / ``--info`` when the count is non-zero.
CSS for ``.dt-stats / .dt-stat / .dt-stat-label / .dt-stat-value /
.dt-stat-unit`` added to ``_DESIGN_TOKENS_CSS``; falls to a
2-column grid below 900px viewport, matching the mockup's media
query.

Switches the type system to the single-family Geist spec referenced
in ``Business/DataTools/geist_spec.md`` and the matching
``datatools_layout_redesign2.html`` mockup. Editorial-serif headings
are out; the product now reads as modern SaaS-tool typography per
the spec's positioning note (§10).
src/gui/theme.py (new)
Implements geist_spec.md §3 verbatim — preconnect + Google Fonts
link for Geist (400/500/600/700) and Geist Mono (400/500), the
canonical ``:root`` token table (§7) plus severity extensions,
and the type scale (§4): h1 32/600/-0.035em, h2 22/600/-0.025em,
h3 18/500/-0.018em, h4 15/500/-0.012em, body 14/400, caption
12.5/400, mono 0.92× ss02. ``apply_theme()`` is the single entry
point.
Two deviations from the spec, both anticipated by spec §6.1:
- ``font-family: var(--font-sans) !important`` on the base rule.
Streamlit applies ``font-family: "Source Sans"`` directly to
``[data-testid="stMarkdownContainer"]`` and a few widget
wrappers at equal-or-higher specificity than the spec's
selector list, so plain inheritance loses the cascade.
- The base selector list explicitly enumerates
``stSidebarNav``, ``stMarkdownContainer``, ``stVerticalBlock``
and a few siblings so Streamlit's per-widget font reset
doesn't reach descendant text.
src/gui/components/_legacy.py
- ``_DESIGN_TOKENS_CSS`` no longer redeclares fonts or the
heading rules — those are theme.py's job (spec §9 says the
spec is type-only; everything below is component chrome).
- Token references switched from ``--dt-*`` to the spec names
(``--ink``, ``--bg``, ``--surface``, ``--border``, ``--accent``,
``--font-sans``, ``--font-mono``, …).
- Sidebar section-label rule tightened to 11.5px / 500 to match
the "Eyebrow" row in spec §4.
- Primary-button text color now also targets every descendant
(``button[kind="primary"] *``) so the inner
``stMarkdownContainer > p`` doesn't pick up
``color: var(--ink)`` from the base rule and render
near-invisible ink-on-ink.
- ``hide_streamlit_chrome`` now calls ``apply_theme`` before
injecting component CSS so the base tokens are defined first.
Acceptance criteria from spec §8 verified at 1920×1050:
- h1 computes ``font-family: Geist``, ``font-weight: 600``,
``letter-spacing: -1.12px`` (= 32px × -0.035em), size ``32px``.
- Body ``<p>`` inside ``stMarkdownContainer``: Geist 400 / 14px.
- Caption: Geist 400 / 12.5px.
- Inline mono filenames: Geist Mono in accent-fill chip.
- No Source Sans Pro leaks into any text the user reads.

DataTools is local-first — "Upload" reads like "send data somewhere
remote", which contradicts the product positioning. Sweep replaces
the user-visible term throughout the UI:
- ``src/i18n/packs/en.json`` + ``es.json``: all ``upload.*`` strings
(heading, intro, uploader labels, empty state, switch-back, etc.)
and ``gate.default_name``. The ``intro_multi`` "no upload anywhere"
phrasing dropped the verb entirely — now reads "nothing leaves
this computer".
- All 9 tool pages: ``st.file_uploader(label="Upload …")`` →
``"Import …"``; matching ``st.info("Upload a …")`` empty-state
banners; ``help="Upload …"`` strings on disabled uploaders.
- ``9_Pipeline_Runner`` + ``5_Column_Mapper``: radio-option text
``"Upload schema/pipeline JSON"`` → ``"Import …"`` plus the
``.startswith("Upload")`` branch guards that read those values.
- ``_home.py``: "**Uploaded files**" → "**Imported files**".
- ``app_demo.py``: "Uploaded file is …" → "Imported file is …".
Internal identifiers left untouched: function names
(``pickup_or_upload``, ``_StashedUpload``), session-state keys
(``home_upload``, ``home_uploads``, ``home_uploaded_*``,
``merger_file_upload``), audit-log event category (``"upload"``),
Streamlit testid CSS selectors. None of those are visible to the
user.
The file_uploader's dropzone button text is a baked-in React
literal that Streamlit's ``label=`` doesn't reach; rewritten at the
DOM level with a small ``_RENAME_UPLOAD_BUTTON_JS`` snippet shipped
through ``st.iframe`` (same pattern the sticky footer uses to mount
on ``<body>``). A ``MutationObserver`` on the parent document re-
applies the swap when Streamlit remounts the dropzone after file
add/remove or page navigation, throttled via ``requestAnimationFrame``.

After upload, two near-identical file lists were shown stacked:
Streamlit's built-in compact chip row inside the dropzone (icon +
``messy_sales.csv`` + size) and the home page's own "Uploaded files"
section beneath it (filename + Remove button). User flagged the
duplication.
Hide ``[data-testid="stFileChip"]`` and its first-child wrapper so
the chip row collapses; the dropzone's borderless ``+`` button is
preserved as the "add more files" affordance, and our "Uploaded
files" list is now the single source of truth visually.

Lifts ideas from the ``datatools_layout_redesign.html`` mockup
(artistic licence, not literal). Two changes:
1. ``.streamlit/config.toml`` ``[theme]`` block — cream paper bg
(#fafaf7), warm sidebar (#f5f4ef), stone ink (#1c1917), burnt
orange primary (#c2410c). Streamlit threads these through its
chrome (focus rings, file-uploader accents, link colors).
2. ``_DESIGN_TOKENS_CSS`` injected by ``hide_streamlit_chrome`` on
every page. Imports Fraunces (display serif), Geist (body sans),
Geist Mono. Restyles, scoped through ``--dt-*`` custom properties:
- Page surface + sidebar — warm cream backgrounds, soft warm
borders, no harsh white.
- Sidebar nav — section labels in tiny uppercase tracking, nav
items with soft hover, active item as a white pill with subtle
shadow.
- Typography — H1/H2/H3 in Fraunces with tightened tracking;
body Geist; inline code Geist Mono with orange-on-cream chip.
- Buttons — primary = dark ink (``#1c1917``) with white text;
secondary = paper surface with warm border; disabled = muted
cream.
- Containers / expanders — editorial cards: 14px radius, 1px
warm border, faint shadow, warm-cream summary headers.
- File uploader — cream dropzone with dashed border + per-file
paper chips.
- Alerts — soft tinted fills (info=sky, success=mint, warn=amber,
error=rose) over the kind-specific palette.
- Inputs, tabs, dataframes — paper surfaces with rounded warm
borders.
Verified at 1920x1050 + 1400x900 on home page (empty + with file
uploaded + with findings rendered) and Clean Text tool page; no
regressions in the white-bar fix from 65b663b.

User screenshot pinned the actual culprit: a horizontal white band
across the FULL viewport width (including over the sidebar) above
the Help/Close footer. Diagnosis:
- ``.stApp`` carries ``zoom: 0.85``, so any descendant sized at
``100vh`` only renders at ~85vh visually.
- At 1920x1050 the visual end of ``.stApp`` is around y=893; the
fixed footer overlays y=1017..1050; the strip in between (124px
at this resolution) is ``body`` painting white through, because
``.stApp``, ``stSidebar`` and ``stMain`` are all shorter than
the viewport.
- The previous "min-height: 100vh/0.85" rule targeted the legacy
``data-testid="stAppViewBlockContainer"``. The current Streamlit
release renamed that testid to ``stMainBlockContainer`` — so the
rule was a no-op for months. Verified the new testid by walking
the live DOM.
Fix: stretch ``.stApp``, ``[data-testid="stSidebar"]`` and
``[data-testid="stMain"]`` with ``min-height: calc(100vh / 0.85)``
so they fill the visible viewport. Keep the block-container's 2rem
``padding-bottom`` (now matching both the new and legacy testids in
case Streamlit rolls it back).
Verified at 1920x1050: sidebar gray extends to y=1050, content area
extends to y=1050, footer overlays the bottom 33px, no white band
between content and footer.

The "white bar" was the footer's near-white background painting
over the bottom of the sidebar. The footer is fixed at body level
with ``left: 0; right: 0`` so it spans the full viewport — its
``rgba(255, 255, 255, 0.97)`` background renders as essentially
white over the sidebar's ``rgb(240, 242, 246)`` gray, producing a
visibly different strip at the bottom of the sidebar (this is what
the diagnostic GREEN tint marked as ``stAppViewContainer``-shaped
because that is the element directly behind it).
Pixel-sampled the bottom row to confirm:
y=860 over sidebar → (240, 242, 246) (gray)
y=870 over sidebar → (255, 255, 255) (footer-painted white)
Fix: in the iframe JS that mounts the footer on ``<body>``, measure
``[data-testid="stSidebar"].getBoundingClientRect().right`` and set
the footer's (and help popover's) ``left`` to that offset with
``setProperty(..., 'important')`` so it beats the ``left:0!important``
fallback in CSS. A ``ResizeObserver`` on the sidebar plus a
``window.resize`` listener keep the offset in sync when the sidebar
collapses or expands.
Sidebar collapsed (width 0 or off-screen) clamps to 0 → footer goes
flush-left as before. Also dropped the no-op ``min-height`` on the
view container from the previous attempt; ``stAppViewContainer`` is
transparent, so stretching it never painted anything.
Verified by injecting the same offset on the live page: bottom row
at y=890 is now ``(240,242,246)`` over the sidebar and only turns
white at x=255 where the content area begins.

``use_container_width`` is being removed after 2025-12-31. Streamlit
log was flooding the terminal with the deprecation notice on every
rerun. Mechanical sweep:
use_container_width=True → width="stretch"
use_container_width=False → width="content"
51 call sites across 11 page files + ``app_demo.py``. Also renamed
the ``local_download_button`` helper's ``use_container_width`` kwarg
to ``width`` (default ``"stretch"``); it has no external callers
passing the old name, so this is a safe rename.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Color-tag diagnostic confirmed the bottom-of-viewport strip was
painted by ``stAppViewContainer`` (it showed GREEN), not by the
block container as the previous two attempts assumed. ``.stApp``
has ``zoom: 0.85`` so 100vh visually renders at 85% — apply
``min-height: calc(100vh / 0.85)`` to the view container itself so
it spans the full visible viewport and there is no gap for its own
background to leak through as a "white bar". Reverts the diagnostic
tints (RED/BLUE/GREEN/GOLD); keeps the 2rem block-container
padding-bottom that reserves room for the fixed footer overlay.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Option 2 (stretching the block container with ``min-height``) did
not close the white gap. Either the rule isn't applying, or the
block container isn't the element that fills the visible bottom of
the page. Tint every plausible container so the eye can tell us
instantly which one paints the bar:
- RED ``stAppViewBlockContainer`` (still has min-height applied)
- BLUE ``stMain`` / ``section[stMain]`` (with its own min-height)
- GREEN ``stAppViewContainer``
- GOLD ``.stApp`` (zoomed)
User reload + report which color shows where the "white bar"
previously was — that names the target.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Option 1 (tightening ``padding-bottom`` from 3rem to 2rem) did not
eliminate the gap. The remaining gap is ``.stApp``'s solid white
background showing through the area below the block container's
natural (content-sized) bottom edge — visible because the home
page's content is shorter than the viewport.
Stretch the block container with ``min-height: calc(100vh / 0.85)``
so the container itself fills the visible viewport. Now the area
between the last finding card and the fixed footer is the block
container's own background, not ``.stApp`` showing through —
visually continuous with the content above.
The ``/0.85`` compensates for ``.stApp { zoom: 0.85 }`` (defined in
``_HIDE_CHROME_CSS``): inside a zoomed container, ``100vh`` renders
at 85% of true viewport height, leaving a 15% gap if used raw.
``box-sizing: border-box`` keeps the 2rem padding part of the
total height instead of stacking onto it.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Diagnostics confirmed the "white bar" the user has been describing is
not a separate element — it's ``[data-testid=stApp]``'s solid white
background (``rgb(255,255,255)``, viewport-locked) showing through the
gap between where page content ends and where the fixed Help/Close
footer overlay begins. ``stApp`` stays put while content scrolls
inside it, which is why the bar "doesn't change when scrolling".
The gap exists because ``render_sticky_footer`` overrides the block
container's ``padding-bottom`` to ``3rem`` (48px) to reserve clear
room for the fixed footer. The footer is only ~32-33px tall (min-
height 32px + 0.25rem top/bottom padding), so ~16px of that reserve
was pure visible white space sitting above the buttons.
Reduce ``padding-bottom`` to ``2rem`` (~32px) — just enough to
prevent content from rendering under the footer overlay, no more.
Eliminates the visible gap without exposing text to clipping.
Also remove the diagnostic banner + click-to-inspect iframe from
the home page now that the bar is identified.

User reported the previous TEST #2 banner appeared at the *top* of
the main content area instead of the bottom. Root cause: on the home
page, ``render_sticky_footer()`` is called at line 107 — before
``st.title()`` — so anything that function injects in document flow
lands at the top of ``stAppViewBlockContainer``. Other pages call
``render_sticky_footer()`` at the end of their script, so the flow
content lands at the bottom there.
Remove the marker from ``render_sticky_footer`` and add it directly
at the very end of ``_home._home_page()`` — after the findings
panels. If this banner lines up with the offending white strip when
scrolled to the bottom, the strip is something rendered at the tail
of the page (likely an iframe wrapper from ``render_findings_panel``
or the block container's ``padding-bottom``).

User confirmed the previous marker landed inside the Help/Close
sticky footer — which is NOT the offending white bar. They want the
sticky footer kept; the white strip they're trying to remove sits
*above* the footer in the main content area.
Move the marker out of ``#datatools-sticky-footer`` and render it
via ``st.markdown`` immediately before the ``st.iframe`` call that
injects the footer. That places it at the very bottom of
``stAppViewBlockContainer`` — exactly where the iframe wrapper
(``stElementContainer``) and the block container's
``padding-bottom: 3rem`` reservation live.
Styled as a red dashed banner so it's unmistakable. If it lines up
with the white strip clipping text on scroll, one of those two is
the culprit and the next commit can target it.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The user reports a "white bar/box" at the bottom of the main content
area that clips text when scrolling. The DOM inspector found only one
fixed-position white element near the viewport bottom —
``#datatools-sticky-footer`` (bg ``rgba(255,255,255,0.97)``,
~33px tall) — so this is my best candidate for what they're seeing.
Append a red marker span "◀ CLAUDE TEST: is this the white bar you
want removed? ▶" inside the footer div so the user can visually
confirm. If the text shows up where they see the offending white
bar, the footer is the right target; if the bar is somewhere else,
this confirms it's a different element.
Temporary — to be reverted in the next commit either way.

Same wrong-testid bug as the Close click handler: the CSS rule
that's supposed to position the hidden ``st.page_link`` off-screen
was selecting ``a[data-testid="stPageLink"]``, but the bare
``stPageLink`` testid is on the OUTER wrapper div — the anchor
uses ``stPageLink-NavLink``. ``:has(a[data-testid="stPageLink"]...)``
matched nothing, so the helper rendered as a full-size visible
row at the bottom of every page (the "large white bar blocking
content" the user reported).
Fix: switch both the ``:has()`` rule and the no-:has() fallback
to ``a[data-testid="stPageLink-NavLink"][href*="close"]``. The
``href*="close"`` form also works for base-path deployments
(``/myapp/close``), matching the click handler's selector.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two bugs combined to make the footer Close a no-op:
1. The helper page_link's anchor carries
``data-testid="stPageLink-NavLink"`` — the bare
``stPageLink`` testid is on the OUTER WRAPPER div, not the
anchor. The old selector ``a[data-testid="stPageLink"]``
matched nothing, so ``helper`` was always ``null``.
2. The fallback ``window.location.href = './close'`` ran inside
the component iframe, so it only navigated the (invisible)
srcdoc iframe. The main app stayed put.
End result: click → nothing visible → shutdown_app never runs →
farewell-script's ``window.close()`` attempt never happens →
user sees the Close button as broken.
Fixes:
- Selector → ``a[data-testid="stPageLink-NavLink"][href*="close"]``.
``href*="close"`` covers both root (/close) and base-path
(/myapp/close) deployments.
- Fallback → resolve the parent window via
``doc.defaultView`` (the parent doc's window) with a
``window.top`` fallback, so the hard-nav navigates the whole
app instead of just the iframe.

Streamlit logs a deprecation notice on every render:
Please replace ``st.components.v1.html`` with ``st.iframe``.
``st.components.v1.html`` will be removed after 2026-06-01.
Replace all 9 call sites (6 tool pages + 3 in ``_legacy.py``).
Both APIs feed ``srcdoc`` to the underlying iframe so the
HTML/JS payload and the cross-frame DOM access pattern
(``window.parent.document``) are unchanged.
``st.iframe`` rejects ``height=0`` (raises ``StreamlitInvalid
HeightError``), so bump every zero-height call to ``height=1``.
1px is effectively invisible — these are script-only iframes, no
visible payload — and avoids the validator.

Footer Close was using ``<a href="./close">`` which triggers a
browser hard-nav. That's a visible page-reload flash, websocket
churn, and slower shutdown than the previous sidebar Close —
which used ``st.navigation``'s soft nav.
Restore the soft-nav path:
- ``render_sticky_footer`` now renders a hidden ``st.page_link``
pointing at ``pages/99_Close.py``. Positioned off-screen via
CSS (``stElementContainer:has(a[data-testid=stPageLink]
[href$=/close])``) so it occupies no layout space but stays in
the DOM, reachable + clickable.
- Footer's Close <button> click handler now dispatches a
programmatic click on that hidden page_link. Streamlit's React
handler picks it up and runs the soft nav (same code path the
old sidebar entry used). Falls back to ``window.location.href``
if the helper link hasn't rendered yet so the button is never
a no-op.
- The page_link call is wrapped in try/except: ``AppTest`` doesn't
populate the page-nav session keys it needs and raises
``KeyError('url_pathname')``. Failure costs only the soft-nav
optimization — Close still works via the hard-nav fallback.

Two follow-ups to the prior sidebar/footer cleanup:
- The "_hidden" section header was still visible in the sidebar
because Streamlit renders ``stNavSectionHeader`` as a sibling of
``stNavSection``, not a child — so the ``:has()`` rule on the
section was hiding the items list but leaving the header
(and its collapse/drilldown marker) behind. Move Activate +
Close into the unlabeled section (key ``""``) alongside Home so
there is no header to leak in the first place, then hide just
the two links via ``stSidebarNavLinkContainer:has(...)`` (with
a defensive ``a[href$=...]`` fallback for browsers without
``:has()`` support).
- The sticky footer was missing on ``pages/_Activate.py`` because
the page never called ``render_sticky_footer`` — added the
call so the Help / Close bar persists when the user follows
the popover's Activate / Manage link.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Collapse the Account section: Activate now lives in the same
hidden sidebar section as Close (single ``_hidden`` group). Both
pages stay registered with ``st.navigation`` so /activate and
/close remain URL-routable for the Help-popover / Close-button
links — only the sidebar entries + their section header are
hidden via CSS.
- Help popover always exposes a license-management link now:
``Activate now →`` when the license is inactive, ``Manage
license →`` when it is active and valid. Both point at
``./activate``.
- Extend the sidebar-hide CSS to also match ``a[href$="/activate"]``
and the section that contains it.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Bump version to 3.0 (src/__init__.py).
- Switch support address to support@unalogix.com.
- Help popover now includes a License section that reads
``src.license.current_state()``:
* When activated + valid: name + expiry date + days remaining.
* Otherwise: "Not activated" + an ``Activate now →`` link
pointing at ``./activate``.
License-state queries are wrapped so a corrupted license file
can't take the footer down — it falls through to the inactive
branch.
- Popover HTML is now built in Python (so the license branch
lives in one place) and passed to the JS as a single string.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three small follow-ups to the sticky-footer rework:
- Left-justify the footer buttons (and reposition the Help popover
to anchor at the left edge so it lines up with its trigger).
- Remove the per-page ``st.divider() + st.caption("Runs locally…")``
trailing block from all 9 tool pages. The new sticky footer
covers that text, so it was rendering as an empty white bar at
the bottom of each tool page.
- Hide the Close entry from the sidebar nav via CSS. The page stays
registered with st.navigation so /close is still routable for the
sticky-footer Close button — only the sidebar link + its section
header are hidden (via :has() on stNavSection).

The duplicate full-width Back-to-Home button at the bottom of every
tool page was reading as a "huge footer." Replace it with a real
slim sticky footer holding two controls:
- Close: <a href="./close"> to the Close page (which shuts down).
Full-page nav is fine here — the process is terminating, so the
session-state-loss concern that retired the previous sticky
footer doesn't apply.
- Help: JS-toggled popover showing version + support@datatools.app.
No navigation, no state loss.
Top-of-page Back-to-Home stays (uses st.switch_page, preserves
state). Add footer.* i18n keys for en + es.

User pulled d9e32e5 (async-writer audit log + re-enabled diagnostics
sidebar) and still sees blank pages. The synchronous-write theory
from the previous round was at most a partial explanation; something
ELSE in the audit-log code path is also taking the page render down
on the user's machine.
Restore the kill switch so the user has a working app while we
diagnose:
- ``src/audit.py``: ``_DISABLED = True`` re-introduced at module
top, each of ``log_event`` / ``log_session_start`` /
``log_page_open`` / ``flush_audit_log`` early-returns. The async
writer thread is never started.
- ``hide_streamlit_chrome``: ``_render_diagnostics_sidebar()`` call
re-gated behind ``if False:``.
The async writer code stays in place — easier to flip the flag back
when we identify the real cause than to rewrite a third time. The
shutdown-flush call in ``shutdown_app`` also stays; it early-returns
on the kill switch and is harmless.
Diagnostic plan for the next session: ask the user for the launcher
terminal output (the new stderr "DataTools audit: writes failing..."
message would tell us if the writer thread DID start and DID fail),
and whether ``~/.datatools/logs/`` is being created at all.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Reported earlier: synchronous file writes in ``log_event`` blocked
the GUI render thread on hostile filesystems (Windows antivirus on
``~/.datatools/logs/`` is the prime suspect). A blocking ``open``
call doesn't raise — try/except can't recover from it — so the
only safe re-enable is to take file I/O off the render path.
Refactor:
- ``log_event`` and friends push events onto a ``deque(maxlen=5000)``
via ``put_nowait`` and return in microseconds.
- A single daemon thread (``datatools-audit-writer``) drains the
queue and writes batches. Holds the queue lock only long enough to
snapshot + clear, then does I/O outside the lock so producers can
keep enqueueing.
- ``audit_log_path()`` is now pure path arithmetic — no ``mkdir``
no ``open``. The writer thread does the directory creation off
the request path, so any hang there only affects the writer.
- Bounded queue means an unwritable disk doesn't unbounded-grow
memory; the queue caps at 5000 and overflow drops OLDEST events
so the most-recent (most-diagnostic) ones survive.
- First write failure prints once to stderr; subsequent failures
are silent so logs don't drown the launcher terminal.
- ``flush_audit_log(timeout_s=0.5)`` drains the queue and signals
the writer to exit; bounded so a stuck disk can't delay shutdown.
Other changes in this commit:
- ``shutdown_app`` now emits a "Session ending" event and calls
``flush_audit_log`` before kicking the os._exit timer, so the
closing session's events make it to disk.
- The Diagnostics sidebar in ``hide_streamlit_chrome`` is
re-enabled (the ``if False:`` gate is removed). Wrapped in
try/except defensively — render errors print to stderr, never
blank the page.
- ``_DISABLED`` kill-switch is gone. The async design IS the
safety mechanism now.
Tests in ``tests/test_audit.py``:
- log_event burst of 1000 events completes in well under 1s
(proves non-blocking).
- Events queued before flush land on disk with the expected JSON
shape; session_start renders; idempotent.
- Pointing the audit dir at a file (so mkdir fails) doesn't hang
or crash the producer.
- Non-JSON extras are str()-coerced rather than dropped.

Reported: after the sticky-footer href fix (be7191a) the back-to-home
click worked but the home-page upload list disappeared. Full-page
navigation via ``<a href>`` doesn't preserve ``st.session_state`` on
the user's Streamlit build.
Trade-off forced: pick visible-from-anywhere sticky footer OR state
preservation. Can't have both because ``st.switch_page`` (soft nav,
preserves state) needs a real Streamlit button widget, and Streamlit
widgets can't be reliably CSS-positioned to the viewport bottom —
Streamlit owns the widget DOM and remounts it on every rerun.
State preservation wins. Going back to the pre-sticky design:
- ``render_sticky_footer()`` becomes a no-op shim. Kept as a callable
so the call sites in every tool page don't have to be touched in
this commit; the original implementation is preserved as
``_render_sticky_footer_DISABLED`` if we ever decide to revisit.
- Every Ready/Coming-Soon tool page (1-9) gets ``back_to_home_link()``
reinstated near the top of the page (visible at scroll-top) AND
``back_to_home_link(key="_back_to_home_link_bottom")`` reinstated
near the bottom of the page (visible at scroll-bottom). Both
instances call ``st.switch_page`` via the existing helper — soft
nav, no full reload, ``st.session_state["home_uploads"]`` and
every other session-state key survive.
User trades the "always-visible while scrolling" sticky behavior for
the upload-list-survives-navigation behavior. The two-button pattern
(top + bottom) was what we had before the sticky-footer experiment;
on short pages both are visible at once, on long pages the user has
one in reach at either end.

Reported: clicking Back to Home in the sticky footer surfaced
Streamlit's "Page not found — Running the app's main page" message
in the user's build.
Root cause: ``url_path="home"`` on the home page's ``st.Page``
registration is treated as an alias for the default page in some
Streamlit minor versions, but the user's build doesn't honour the
alias for the page that ALSO has ``default=True``. The default page
is served at the root URL ``/``; ``/home`` is treated as a missing
page on that build.
Switch the footer anchor's href from ``"home"`` (which resolved to
``/home`` from any tool-page URL) to ``"./"`` (resolves to the
current document's directory, which on a single-segment URL is the
server root → default page → Home). Robust across Streamlit minor
versions regardless of how the url_path alias is interpreted.

User confirmed: with the audit-log kill switch (1caedbb) in place,
pages render. So the hang was 100% in the audit-log file writes —
``open()`` blocking on Windows somewhere — not in the chrome
additions disabled during bisection.
Two of those three additions are pure UI and have no filesystem
exposure, so they're safe to re-enable now:
- **Sticky footer**: pure CSS + a components-html iframe whose JS
appends a div to ``parent.document.body``. No disk touch. The
user just reported losing the Back-to-Home button to the
bisection commit — restoring this brings it back.
- **Compact-spacing CSS layer**: gap reductions on stVerticalBlock
/ stHorizontalBlock, slim heading margins, slim hr / caption /
expander / button / metric padding. Pure CSS.
What stays disabled:
- **Audit-log writes** (``src/audit.py:_DISABLED = True``). Any
resumption needs an async-write design with a hard timeout so a
stuck filesystem can't hang the GUI render.
- **Diagnostics sidebar**: it calls ``audit_log_path()`` which
itself does a ``mkdir()`` — and a hanging mkdir would re-introduce
the same blank-pages symptom. Will re-enable once the audit log
is rewritten not to block.

Reported: uploading multiple files on the home page and clicking Run
analysis blew up with
StreamlitDuplicateElementKey: key='_findings_open_02_text_cleaner'
when two uploaded files both had Clean Text findings.
Root cause: ``render_findings_panel`` is invoked once per uploaded
file from ``_home.py``, but the per-tool jump button used a
filename-agnostic key:
key=f"_findings_open_{tool_id}"
Two files both flagging Clean Text → two buttons with identical keys
→ Streamlit rejects the second one.
Fix:
- Add ``key_namespace: str = ""`` to ``render_findings_panel``. The
helper hashes it (sha1 truncated to 8 chars) and appends to every
button key, so different namespaces produce different keys but the
same namespace stays stable across reruns.
- The home page now passes the filename:
``render_findings_panel(findings, header=f"📄 {name}", key_namespace=name)``.
- The single-call site in ``upload_and_analyze_section`` (the legacy
helper, only used outside the new home-page path) keeps the default
empty namespace, which is fine because that path renders findings
for ONE file at a time.

Reported: every page renders empty in the main body even after the
audit-log defensive-wrap commit (59c6d0f). Close button also doesn't
trigger shutdown — that page is blank too. Sidebar nav still renders,
so the chrome path that runs on every page is the suspect.
Three chrome additions land all at once and are temporarily turned
off so the user can see whether bare chrome restores rendering:
1. **Sticky footer (``render_sticky_footer``)**: short-circuited with
``return`` at the top of the function. The CSS-injection +
components-html iframe mechanic is the highest-suspicion item —
if the iframe script throws or the CSS interacts badly with the
user's Streamlit / Python build, the side effects can be
page-killing on theirs while invisible on ours. The original body
is preserved as ``_render_sticky_footer_DISABLED`` so re-enabling
is a one-line change.
2. **Diagnostics sidebar (``_render_diagnostics_sidebar``)**: call
site in ``hide_streamlit_chrome`` is gated by ``if False:``.
Wrapping in try/except (the previous commit) caught exceptions
but didn't help — silent partial renders inside
``with st.sidebar: with st.expander: ...`` can still leave the
render stack in a bad state on some Streamlit versions.
3. **Compact-spacing CSS layer**: the ``gap: 0.5rem !important;`` on
``stVerticalBlock`` / ``stHorizontalBlock``, the slim heading
margins, the slim hr / caption / expander / button / metric
rules — all stripped back to the pre-compact ``_HIDE_CHROME_CSS``.
The ``gap`` rule in particular is a suspect: if the user's
Streamlit version doesn't render stVerticalBlock as a flex
container, the rule is harmless; if it does and interacts badly
with overflow, content could be clipped.
What's deliberately KEPT enabled:
- The audit-log calls (already wrapped from 59c6d0f).
- ``log_page_open`` calls in tool pages (already wrapped internally).
- All UI changes pre-compact (the unified tool-page layout, the
download-button helper, etc.).
If pages render after this commit, we know it's one of the three
disabled items above and can bisect further. If they still don't
render, the cause is in code that pre-dated the audit-log work and
the bisection has to keep going.

Reported: after pulling commit c73d716 (audit log) the main body of
every page showed empty. Sidebar nav still worked.
Diagnosis: the most likely path is that something inside the audit
calls — ``_render_diagnostics_sidebar()`` calling ``audit_log_path()``,
or ``log_session_start()`` itself — raises during ``hide_streamlit_chrome``
on the user's environment (Python 3.14 on Windows, a less-tested
combo than the test environment). Streamlit's script runner sees the
exception, and on some chrome paths it eats it without surfacing an
error block, leaving the page body empty.
The audit log is best-effort by design. Make that contract real:
1. ``hide_streamlit_chrome`` now wraps both ``log_session_start()``
and ``_render_diagnostics_sidebar()`` in try/except. Errors print
to stderr (so the developer running ``python -m src.gui`` sees
them in the launcher's console) but never bubble up to kill the
page render.
2. ``audit_log_path()`` already had a tempdir fallback for the
primary mkdir failure, but the SECOND mkdir wasn't protected
either. Restructured to a two-level fallback: configured dir →
tempdir → ``/dev/null`` (or ``NUL`` on Windows). The last fallback
ensures the function never raises; ``log_event``'s own try/except
handles the eventual unwritable-file case.
3. ``log_page_open(slug)`` now has an outer try/except so it cannot
raise either — protecting every tool page's render path.
If a user reports the same symptom again, the launcher terminal will
now show a real traceback explaining what's wrong, and the GUI will
still render normally.

New ``src/audit.py`` module records GUI actions to a per-session
JSONL file under ``~/.datatools/logs/`` (overrideable via
``DATATOOLS_AUDIT_DIR``). The file is human-readable (one JSON
object per line, each with a ``message`` field) AND trivially
machine-parseable — the support flow is "client mails the file,
we read it and explain what went wrong."
Format example::
{"ts":"2026-05-17T05:30:00.123+00:00","level":"info","category":"session",
"session":"a1b2c3d4","message":"Session started",
"platform":"Windows 11","python":"3.14.0","user":"Michael Dombaugh",
"log_file":"C:\\Users\\Michael Dombaugh\\.datatools\\logs\\datatools-...jsonl"}
{"ts":"...","category":"upload","message":"Uploaded customers.csv",
"filename":"customers.csv","bytes":24813}
{"ts":"...","category":"analyze","message":"Analyzed customers.csv (3 findings)",
"filename":"customers.csv","findings":3,"rows":120,"cols":8}
{"ts":"...","category":"tool_run","message":"Clean Text run",
"page":"2_Text_Cleaner"}
{"ts":"...","category":"error","level":"error",
"message":"analyze(weird.csv): EmptyDataError: No columns to parse",
"filename":"weird.csv","outcome":"empty_after_repair"}
Public API:
- ``log_event(category, message, **extra)``
- ``log_session_start()`` — idempotent banner with platform info
- ``log_page_open(slug)`` — emit a ``nav`` event, deduplicated per
Streamlit session so reruns don't spam the log
- ``log_exception(where, exc, **extra)`` — convenience wrapper
- ``audit_log_path()`` / ``audit_log_dir()`` — for the UI
Wired in at:
- ``hide_streamlit_chrome``: stamps session start, mounts a small
"🩺 Diagnostics" expander in the sidebar with the log path and
an "Open log folder" button so the user can grab the file to
attach to a support email.
- Home page: ``upload`` event on every new file, ``upload`` event
on per-file remove, ``analyze`` event with file count when
Run-analysis fires.
- ``_run_analysis_on_upload``: ``analyze`` event with rows / cols /
findings count per file, plus ``error`` events on every caught
exception (empty upload, empty after repair, pandas EmptyDataError,
generic Exception).
- Every Ready tool page (1, 2, 3, 4, 5, 9): ``tool_run`` event
immediately after the primary action stashes its result.
- Every tool page (1-9): ``log_page_open(slug)`` on render — deduped
via session state so we don't get one event per Streamlit rerun.
Safety:
- ``log_event`` wraps every write in try/except. A broken audit
log must NOT crash the GUI.
- Non-JSON-serializable extras are ``str()``-coerced before writing.
- File CONTENTS are never logged. We capture filename, byte count,
and (in the analyzer) a 12-char sha1 fingerprint of the bytes so
the same file re-uploaded gets the same trace.
- License keys, session cookies, etc. are not logged.
- ``DATATOOLS_AUDIT_DIR`` env var lets tests redirect writes into a
tmp dir.

Two reported issues addressed together because they're the same UX
flow (home findings panel → jump to relevant tool).
(1) Format-Standardizer recommendations weren't firing.
Reported: uploading a file from the format-cleaner test corpus
(``24_format_dates.csv``, ``25_format_phones.csv``,
``29_format_currencies.csv``, ``30_format_integration.csv``) showed
zero "Standardize Formats" recommendations even though the columns
clearly mixed multiple date / phone / currency formats.
Two underlying causes:
- ``_detect_inconsistent_date_format`` required two MATCHES per
distinct format. A test column with N rows each in a different
format had ≤1 match per format and was silently passed over.
Loosened to "≥1 match per format" — the inconsistency signal is
the presence of ≥2 distinct formats, not their volume.
- Only date inconsistency was detected. Phones, currency, and
booleans (the other format-standardizer fix categories) had no
detector at all.
Added three new detectors:
- ``_detect_inconsistent_phone_format``: nine phone-format regexes
(plain-10, US paren / dash / dot / space, +country, extension,
intl plus). Fires when a column is ≥35% phone-shaped AND mixes
≥2 formats.
- ``_detect_inconsistent_currency_format``: thirteen currency regexes
covering US ($1,234.56 / $1234.56), EU (€1.234,56), India lakh
notation, Swiss apostrophe, trailing-symbol, parens-negative,
prefix-currency-code, suffix-currency-code, and negative variants.
Same fire criteria as phone.
- ``_detect_inconsistent_boolean_format``: column is ≥80% boolean
tokens (yes/no/y/n/true/false/1/0) AND uses ≥3 distinct surface
forms (e.g. yes / Y / true / 1 mixed together).
Verified on every file in ``test-cases/format-cleaner-corpus/``:
24_format_dates, 25_format_phones, 29_format_currencies all now
produce a format-standardizer Finding. The integration test file
flags all three.
The threshold loosening (from 50% to 35% of values format-shaped) is
still strict enough to avoid false-positives on free-text comment
columns where a few cells happen to look phone- or date-shaped.
(2) The "Open <Tool>" jump links blended into the page.
Reported: the per-tool jump links inside the home findings panel
were too subtle to notice.
Replaced ``st.page_link`` with ``st.button(type="primary")`` so the
buttons render in Streamlit's primary-action red colour, matching the
"Clean Text" / "Find Duplicates" / etc. run buttons. Click handler
delegates to ``st.switch_page(page_slug)`` so it's still a soft
in-app navigation (no full reload).
2220 tests pass.

Reported: the sticky footer rendered, but the Back to Home button
inside it wasn't visible.
Likely cause: ``st.markdown`` inserts the footer div inside Streamlit's
content tree, which sits under ``.stApp { zoom: 0.85 }`` (our compact
scaler) and several nested padding/positioning contexts. Streamlit's
own ``<a>`` styling rules can also colour-collide with our anchor.
Switch the mount strategy. Two passes:
1. CSS rules go to the parent document via ``st.markdown`` as before,
but every property carries ``!important`` and the selectors key on
``#datatools-sticky-footer`` (id, not class) plus a dedicated
``.datatools-sticky-footer-link`` class on the anchor — so
Streamlit's default ``<a>`` styles can't override colour or
padding. ``z-index: 2147483646`` keeps the footer above
anything else in the page.
2. The footer DOM node itself is created by a script inside a
zero-height ``streamlit.components.v1.html`` iframe. The script
does ``window.parent.document.body.appendChild(...)`` so the div
lives as a direct child of ``<body>`` — outside ``.stApp``,
outside every Streamlit container, free of every parent's
``zoom`` / ``transform`` / ``overflow`` rules.
If the cross-frame access ever fails (Streamlit sandbox config
change), the script falls through to appending inside the
iframe's own document — degraded but still visible.
Each rerun replaces any prior ``#datatools-sticky-footer`` so we
don't accumulate stacked footers on every script pass.
2220 tests pass.

Two unrelated UX issues addressed in one sweep across all nine tool
pages because they share the same edit surface.
(1) Sticky footer replaces the top + bottom back-link buttons.
Reported: a big white empty footer space at the bottom of every page;
the Back to Home button at the top scrolled out of view on long pages.
New ``render_sticky_footer()`` helper in ``components/_legacy.py``
injects a fixed-position bar at ``bottom: 0`` of the viewport with:
- A border-top so it visually reads as a non-movable bar.
- A semi-transparent background (rgba 0.96 + ``backdrop-filter: blur``)
so content underneath shows through faintly when the user scrolls.
- A styled ``<a href="home">`` anchor (not an ``st.button``) because
Streamlit widgets can't be CSS-positioned reliably — Streamlit owns
the widget's DOM container and re-mounts it on every rerun. A real
anchor sits exactly where the CSS puts it and triggers Streamlit's
URL routing to the home page.
- ``padding-bottom: 3.5rem`` on the main container so the last widget
isn't hidden behind the bar.
Called once per tool page, immediately after ``hide_streamlit_chrome()``
so it renders even on pages that ``st.stop()`` early before any other
content runs. The old top-and-bottom ``back_to_home_link()`` calls are
removed from every tool page; their entry/exit points were dropping
the button when the script short-circuited.
(2) Tool-page headers now localize.
Reported: switching the sidebar language picker to Spanish left the
tool page's title + caption in English. Root cause: every page had
hard-coded ``st.title("✂️ Clean Text")`` / ``st.caption("Trim
whitespace...")`` strings.
Added per-tool ``tools.<id>.page_title`` and
``tools.<id>.page_caption`` keys to ``en.json`` and ``es.json`` for
all nine tools. Routed each page's title/caption call through ``t()``.
Verified: with ``ui_lang=es`` set, the Clean Text page now renders
"✂️ Limpiar texto" + the Spanish caption.
Updated ``tests/gui/test_smoke.py::EXPECTED_SUBSTRINGS`` so the
``es`` column for each tool page asserts the actual Spanish string
(was a duplicate of the English string back when the page bodies
were English-only).
2220 tests pass.

Reported: too much whitespace between widgets, dividers, and headings.
Compact-spacing CSS layer added to ``_HIDE_CHROME_CSS`` (so it applies
on every page that calls ``hide_streamlit_chrome``):
- ``[data-testid="stVerticalBlock"]`` and ``stHorizontalBlock`` gap
trimmed from Streamlit's default ~1rem to 0.5rem.
- Heading margins (h1-h4) tightened — h1/h2/h3 used to leave 1-1.5rem
above; now 0.25-0.5rem.
- ``hr`` (``st.divider()``) drops from 1rem above+below to 0.4rem.
- Markdown paragraphs and captions: 0.25rem bottom margin instead of
the default 1rem.
- Expander summary padding reduced (0.35rem top/bottom).
- File-uploader, button, and metric tiles: trimmed internal padding.
Also slimmed the main-container padding from 1rem top / Streamlit
default bottom (~6rem) to 0.5rem top / 0.75rem bottom.
The existing ``zoom: 0.85`` on ``.stApp`` is kept — the user wanted
*less white space*, not *smaller content*, and dropping zoom would
shrink type alongside everything else.
2220 tests pass.

Reported: user asked whether we can send Alt+F4 / Ctrl+W to the
browser from JavaScript to force-close a tab.
Honest answer that's now baked into the hint message: NO. Synthesized
keyboard events from page JS only reach DOM event listeners, not the
browser chrome or the OS. There is no flag, API, or trick that lets
a page close a tab the user opened themselves. The page CAN close a
window it opened (window.opener trail) or one whose display-mode is
``standalone`` (Chrome/Edge ``--app=URL``) — that's what
``python -m src.gui`` arranges, and that's the path that actually
closes the window without a manual Ctrl+W.
Improvements landed:
1. ``isStandalone(win)`` detects Chrome --app windows up front
(``matchMedia('(display-mode: standalone)').matches``). In a
regular tab the manual hint surfaces immediately on the
"Close this window" click; in --app mode we only show it if the
close attempt actually fails.
2. ``fallbackToBlank(win)`` navigates the tab to ``about:blank``
via ``location.replace`` (no history pollution) so the user
sees a clean empty tab instead of the farewell overlay frozen
over Streamlit's connection-error banner. They still have to
Ctrl+W the blank tab, but the screen is no longer a misleading
"did it close or not?" mess. Fires 250 ms after a failed close
in --app mode (very rare path), or 1.5 s in a regular tab so
the user has time to read the hint.
3. Hint message rewritten in en + es to explain WHY the close is
blocked (browser security — not something we can override), to
acknowledge the Alt+F4 / Ctrl+W question directly (those don't
work either, for the same reason), and to point at
``python -m src.gui`` as the path that gives a clean auto-close.
2220 tests pass.

Two issues, same fix surface.
(1) Reported crash on Back-to-Home:
StreamlitAPIException: Could not find page: app.py.
``st.switch_page("app.py")`` doesn't work under ``st.navigation`` —
the entry script is the nav manager itself and is not a registered
page. The fix needs to pass an ``st.Page`` object whose script
identity matches one registered in the nav.
First-pass attempt (``from src.gui.app import _home_page``) hit a
worse failure: importing ``app.py`` from inside a tool-page render
re-executes the nav setup with the WRONG "main script" context, so
every ``st.Page("pages/N_foo.py", ...)`` call in ``_build_navigation``
fails with "file could not be found".
Extract the home renderer into its own module ``src/gui/_home.py``
which has no top-level Streamlit side effects. Both the nav manager
and the back-link helper import ``_home_page`` from there. The Page
object built at click time has the same callable identity as the one
registered, so ``st.switch_page`` resolves it.
(2) Reported UX: the back button scrolled out of view on long pages.
Add a second ``back_to_home_link(key="_back_to_home_link_bottom")``
call near the footer of every tool page (1-9). The unique key avoids
widget-id collision with the top instance. Coming-Soon stubs get it
unconditionally; Ready tools render it only after a result exists
because the page short-circuits with ``st.stop()`` before then —
when no result is on screen the page is short enough that the top
link is sufficient.
2220 tests pass.

Reported: clicking "Open Downloads folder" was opening the Documents
folder instead of Downloads. Root cause is the classic Windows
gotcha: when the path contains a space (e.g.
``C:\Users\Michael Dombaugh\Downloads``), Python's
``subprocess.Popen`` packs the ``/select,...`` argument into a single
quoted token, and Explorer's ``/select`` argument parser does NOT
accept that form — it silently falls back to whatever the user's
default Explorer view is (typically Documents).
Resolution paths considered:
- ``shell=True`` with a hand-built command string — works but opens
the door to shell-injection if a file_name ever contained a quote
or special char.
- ``cmd /c start "" explorer /select,...`` — same parsing issue.
- ctypes ShellExecuteW — pulls in a Windows-only dependency.
- **Skip /select. Open the folder directly.** ✓
Going with the last. ``explorer <folder>`` reliably opens the folder
regardless of spaces in the path; the user finds the freshly-saved
file by its name. The previous "highlight the file" nicety wasn't
worth the path-parsing fragility — every user folder on Windows is
``C:\Users\<name>`` and every Windows username can contain a space.
macOS keeps the ``open -R <file>`` reveal-in-Finder path because
macOS argument parsing is sane and that's a strict UX win.
2220 tests pass.

Reported: clicking "Open Downloads folder" did nothing visible. The
previous implementation called ``os.startfile(folder)`` on Windows,
which is known to silently no-op or open Explorer behind the active
window in some configurations (Streamlit running headless, no
foreground rights inherited by the click handler thread, etc.).
Switch to the more reliable ``explorer /select,<file>`` form:
- Opens Explorer with the just-saved file pre-highlighted instead of
just navigating to the folder — better UX than the old behavior.
- explorer.exe is a real GUI process that's spawned in the user's
session with foreground rights, so it shows up on top.
- Fallback chain on Windows: ``/select`` first, then plain
``explorer <folder>``, then ``os.startfile`` as a last resort.
macOS upgraded the same way: ``open -R <file>`` reveals in Finder
rather than opening the directory.
Linux: no reliable cross-distro reveal, so ``xdg-open <folder>``.
Plus user feedback at the call site:
- On successful dispatch: ``st.toast("Opening <folder>", icon="📂")``
— confirms we tried, in case the window comes up behind the
browser.
- On dispatch failure: ``st.warning`` with the full path the user
can copy/paste into their file manager manually.
2220 tests pass.

Switch the download mechanic from "browser <a download> with a data:
URL" to "write the bytes directly to the user's Downloads folder and
show them the exact path". DataTools runs as a local Streamlit app,
so the "server" IS the user's machine — there's no reason to go
through the browser save dialog at all.
Flow:
1. Click "Download <something>" button (rendered as a regular
``st.button``, so no widget-collision issues).
2. Bytes are written to ``Path.home() / "Downloads" / file_name``
(overwriting any same-named file).
3. The page reruns and renders a success caption with the absolute
path the file landed at.
4. An "📂 Open Downloads folder" button appears. Clicking it pops the
OS file manager via ``os.startfile`` (Windows), ``open`` (macOS),
or ``xdg-open`` (Linux).
Why this is better than the previous HTML-data-URL helper:
- Unambiguous about where the file went — user sees the full path,
not "wherever your browser was configured to save".
- The data: URL approach base64-inflated the page payload by 33% and
bloated for large outputs; server-side write is byte-for-byte.
- No more browser-side widget collision class of bug.
- The save action is a real Streamlit button, so the existing widget
semantics (disabled, help tooltip, key isolation) work without
workarounds.
API surface unchanged. New canonical name ``local_download_button``;
``html_download_button`` is kept as a back-compat alias that points
at the same implementation — every existing call site continues to
work without edits.
Tests are protected from polluting the developer's home dir via a
``DATATOOLS_DOWNLOADS_DIR`` env var override returned by the new
``_downloads_dir()`` helper. Smoke verified end-to-end via AppTest:
click → file appears in tmp dir → success banner shows path →
open-folder button renders.
2220 tests pass, 91 skipped, 35 s.

Reported: uploading 13_non_latin_scripts.csv made the home page bubble
a ``pandas.errors.EmptyDataError`` traceback up through the page
chrome instead of surfacing as a per-file error. In a multi-file
analysis run that kills every other file's results too, which is
worse than the symptom itself.
Wrap ``_run_analysis_on_upload`` in proper error handling:
- Empty bytes ``getvalue() == b""`` short-circuits with a synthetic
error Finding telling the user the upload was zero-byte and to
re-upload.
- Empty ``repair.repaired_bytes`` (file was all NULs / BOM / stripped
to nothing) likewise surfaces as a synthetic Finding rather than
reaching pd.read_csv.
- ``pd.errors.EmptyDataError`` from pandas is caught and rendered as
a Finding that names the file, its byte size, and suggests opening
it in a text editor to verify the header row matches the data row
delimiter.
- Any other exception during read/analyze is caught and surfaces as
a Finding via ``format_for_user`` so the user gets a clean message,
not a Python traceback.
Each file in a multi-file run now stands alone: a bad file produces
one red banner in its own card, every other file analyzes normally.
The 13_non_latin_scripts.csv corpus file is 249 bytes of valid UTF-8
on disk and parses cleanly under the same code path locally — the
user's specific symptom is likely a zero-byte upload (browser /
network / Python 3.14 + Streamlit edge case). The new ``empty_upload``
finding will name the bytes count so they can confirm.

There is no JavaScript override for browser tab-close security:
``window.close()`` only succeeds on windows JS opened (Chrome --app
windows qualify; a regular browser tab does not). What we can do is
make the --app path easier to hit and the failure case more
actionable.
Three changes:
1. ``src/gui/__main__.py`` — extend browser detection. PATH lookup
now also looks for ``msedge`` / ``microsoft-edge``; Windows install
candidates include the Edge install path; macOS candidates include
Edge and Chromium. Edge is Chromium-based, supports ``--app``, and
ships on every Windows 10+ machine — so users without Chrome no
longer fall through to the regular browser tab. When the fallback
IS hit, print a warning to stderr explaining why Close-from-page
will require Ctrl+W. Renamed ``_find_chrome`` to
``_find_app_browser`` to reflect the broader scope.
2. ``_FAREWELL_SCRIPT_TEMPLATE`` in ``components/_legacy.py`` —
factor close attempts into a ``tryClose`` helper that runs three
escalating tries: standard ``win.close()``, the
``win.open('', '_self')`` history-rewrite trick (no-op in modern
Chrome but free), and ``win.top.close()``. Auto-close on paint AND
the manual button now both call this helper. Skip the manual hint
if the close eventually succeeded between the click and the 250 ms
timeout.
3. ``quit.close_hint`` in en/es i18n packs — rewrite the message to
tell the user honestly that this is a browser security restriction,
tell them the Ctrl+W keystroke that works, and point them at
``python -m src.gui`` for the auto-closing app-mode experience.
2008 tests pass.
