[0.9.4] - 2026-06-25

Slide entropy scorer was returning NaN when deck had fewer than 4 slides — zero-division bug, embarrassing, Kenji spotted it during the Brauer demo and I wanted to die (PDC-1147)
TAM/SAM/SOM extractor no longer crashes on decks that spell it "TAM / SAM / SOM" with spaces around slashes. Regex was too strict. Three hours of my life gone. Three.
Fixed "founder faces detected: 0" false positive on slides with heavy drop shadows — the vision pipeline was eating the face region. Bumped contrast threshold from 0.31 to 0.47 (calibrated against the test corpus, don't touch it, see notes/threshold_history.txt)
PDF text layer extraction now falls back to OCR automatically when the layer is encrypted or empty. Previously it just returned {} silently like a coward. (fixes #PRB-992, reported by Fatima like three weeks ago, sorry Fatima)
competitorSlideExists() — was always returning true because I left a return true stub in and never came back to it. It has been like this since v0.8.1. Nobody noticed until now. Cool.
Corrected off-by-one in slide numbering output. Deck page 1 was being labeled page 0 in the autopsy report. Confusing everyone. (PDC-1139)
Memory leak in the batch processing queue — promise chain wasn't getting cleaned up after timeout. Fixed with a proper finally block. // pourquoi je n'ai pas fait ça dès le début

Autopsy report PDF generation is ~40% faster after switching from pdfkit to our custom renderer for table layouts. Not perfect but Dmitri said it was "acceptable" which from Dmitri means it's good
Better detection of "hockey stick" revenue projections — now flags decks where projected growth exceeds 10x in 18 months AND has no footnote. Previously only caught 10x with no caveats at all. Nuance!
Traction slide classifier retrained on 200 new examples. F1 went from 0.71 to 0.79. Could be better. Will be better. Eventually.
redFlagSummary() output is now sorted by severity descending instead of by slide order. Makes the executive summary actually useful
Added Spanish-language deck support to the keyword extractor — mercado, tracción, inversión etc. now map correctly. Básicamente porque tuvimos tres decks en español la semana pasada y cero funcionó bien
CLI --verbose flag now actually does something (PDC-1098, open since February, unbelievable)

Korean and Japanese deck support still broken, multibyte PDF parsing is a whole thing, tracked in PDC-887, not touching it this cycle
The "team slide completeness" score goes haywire on decks where the founding team section is split across two slides. Workaround: merge slides before upload. Real fix: TODO, ask Priya if she has bandwidth next sprint
Batch mode with >50 decks will occasionally stall at 94% — seems to be a race condition in the worker pool but I can't repro it reliably. If it happens, just re-run, it clears itself. (PDC-1141, open)
--output json flag produces valid JSON but the slides array is 1-indexed in the metadata and 0-indexed in the content blocks. I know. I know. Don't file another ticket about it

Hotfix: autopsy report would include raw S3 presigned URL in the output JSON when redact_sources was set to true. Not great. (PDC-1121)
"No problem identified" decks were still generating a three-page problem analysis section. (это было смешно если честно)

Initial batch processing mode (--batch flag) — processes multiple decks from a directory
fundability_score field added to JSON output (experimental, not in docs yet, Kenji is writing them)
Support for PPTX input format alongside PDF

Initial public release of PitchDeck Coroner. It works. Mostly.
