Replaces uppercase_only bool with casing string parameter. Adds
known_start/known_end support for filtering and gap-width measurement.

Supports casing (lowercase/uppercase/capitalized), known_start/known_end
filtering with gap-width measurement of the unknown portion only.

Generate first x last name combinations from associate lists, apply
Title Case or UPPER casing, measure rendered widths, and return matches
within tolerance. Also checks associate name variants (initials,
nicknames) with deduplication.

The full-name solver collected all results into a Vec with no limit,
causing OOM crashes for realistic targets where millions of valid
first×last combinations exist. Thread max_results through
solve_subtree, dfs_first, and the Cartesian product loop so the
search stops early once enough results are found.

Thread EquivClasses and deduped_allowed through solve_subtree, dfs,
generate_prefixes, handle_solve, and dfs_first (full_name). The DFS
hot loop now iterates deduped representatives instead of all allowed
chars, and expand_match restores full class-member variants at match
time. This reduces branching factor for charsets with metrically
identical glyphs while preserving complete result sets.

Foundation for glyph equivalence class optimization. Groups charset
characters with identical metric signatures (width table columns/rows,
left/right edges, optional extra columns) into equivalence classes
using exact f64::to_bits() comparison. Includes 3 unit tests covering
duplicate detection, all-unique case, and extra column splitting.

Group metrically identical characters into equivalence classes to reduce
the DFS branching factor from N to K per node, with Cartesian product
expansion on matches to recover all solutions.

Replace the click-to-analyze and spot-detection flows with an automatic
SSE-driven analysis pipeline. After upload, an EventSource connects to
/api/doc/{id}/analyze and reloads page data as each page completes,
consuming pre-computed analysis from the page data endpoint.
Co-Authored-By: Claude Opus 4.6 <[email protected]>
Replace the old /api/redaction/analyze and /api/redaction/spot endpoints
with a new /api/doc/{id}/analyze SSE endpoint that pre-computes all
analysis during upload. The page data endpoint now returns pre-computed
analysis results instead of requiring per-redaction API calls.

Wire together the per-page pipeline: OCR -> LLM redaction detection ->
guided OpenCV search -> font detection with masking -> pixel alignment.
Includes font caching per line and progress callbacks.
Co-Authored-By: Claude Opus 4.6 <[email protected]>
Adds a new detect_font_masked() function that masks redaction boxes to
white (255) before running pixel-based font detection on the full line
crop. This replaces the fragile approach of cropping just the left/right
portion of a line, which lost signal from narrow crops and coordinate
mismatches. The Dice-based scoring naturally ignores masked (white)
regions since they contain no ink pixels.

Add find_redaction_in_region() that searches for a black rectangle
within a specific page region identified by the LLM. Uses a lower
minimum area threshold (100px vs 500px) since the LLM provides
spatial guidance, preventing merged redactions and false positives.

Introduce llm_detect.py that sends OCR lines to Claude Haiku to identify
redaction locations via broken text patterns (garbled chars, brackets,
pipes). The LLM returns boundary words which are mapped back to pixel
positions using OCR character data. Includes comprehensive tests covering
single/multiple redactions, line start/end edge cases, and error handling.

Instead of using a neighboring line (which may have a different font/size,
e.g. email header vs body text), crop the non-redacted left or right
portion of the actual redacted line for font detection. Falls back to
clean neighbor lines only when neither side has enough text (>=50px).

Replace OCR-based offset calculation with pixel alignment that slides
rendered text across the page image to find the exact position with
maximum Dice overlap. Also fix char filtering to use center-point
(c.x + c.w/2) instead of right-edge, recovering characters like "nt"
in "Sent" that partially overlap the redaction box.

Redaction boxes corrupt OCR text and add spurious dark pixels that
break pixel-based font scoring. Now uses wider crop padding (3x)
and prefers the nearest non-overlapping line for font detection.
Co-Authored-By: Claude Opus 4.6 <[email protected]>
Replace word-width MAE scoring with pixel-overlap Dice scoring in both
_full_search() and _fine_search(). Both functions now accept a line_crop
parameter and use _score_font_line_pixel() instead of _score_font_line().
Comparisons are flipped (higher is better). The size range is now derived
from the OCR line height instead of the fixed SIZE_RANGE constant, and
uses step=1 since pixel scoring has sharp peaks at the exact font size.
Co-Authored-By: Claude Opus 4.6 <[email protected]>
Add _score_font_line_pixel() which renders candidate text and compares
pixels against the actual page image using Dice coefficient overlap.
This captures glyph shape differences that the old word-width MAE
approach cannot distinguish (e.g. serif vs sans-serif).

Reorganize the monolithic 1,436-line frontend into 9 focused modules:
types, state, dom, canvas, viewport, associates, popover, solver, main.
No build step — browsers load ES modules natively. JSDoc @typedef
annotations provide type safety via @ts-check + jsconfig.json.

Without flex properties, #viewer-section collapsed to content
height (just the controls bar), giving the workspace 0 height
and causing zoom to compute as 0%.

- Remove unused detect_redactions import from app.py
- Add de-duplication check in dblclick handler to prevent
creating duplicate redaction entries for the same dark region

Shift+drag now adjusts gap width (was ctrl+shift+drag).
Manual redaction marking via shift+drag is removed;
users now double-click to spot-detect redactions.

Extract inline analysis logic from the analyze endpoint into a reusable
_run_analysis() helper function, then add a new /api/redaction/spot
endpoint that chains spot_redaction detection with analysis in one call.
