+Stage 08/09 OCR misread (2026-07-11, previously flagged in plan.md as a

+empty/None, on every psm mode tried with plain detector.read_int, even
+though the crop and its thresholded/upscaled version both looked perfectly
+clean by eye (scratchpad/probe_event_stage_ocr.py, probe_ocr_psm_sweep.py)
+-- confirmed live NOT a navigation/timing bug this time, since rows
+710/883/1055 ("10"/"11"/"12") read correctly in the same run. Root cause,
+isolated via scratchpad/probe_ocr_fix_08_09.py: tesseract's segmentation
+struggles with this specific tight edge-to-edge crop (no surrounding
+whitespace margin) for a leading-zero digit pair specifically -- adding a
+plain white border around the upscaled crop before OCR fixed both "08"
+and "09" to their exact correct values at every psm mode tried, without
+affecting the already-working "10". Ported as detector.read_int_bordered,
+now used for all EVENT_STAGE_ROW_Y reads in _scan_stage_rows_once.
+
+The same live run also confirmed the sweep itself succeeded end-to-end
+(AP 233->14, credits +5,892, screenshot-confirmed safe return home) but
+still logged "unrecognized_state" instead of "swept" -- the
+_watch_sweep_result outcome-logging bug flagged after Phase 14 follow-up
+#5 as "not yet re-verified live" was, it turns out, still broken, just for
+a DIFFERENT reason than the POST_SWEEP_DISMISS_ROUNDS timing budget that
+fix targeted. Root cause this time, isolated with zero AP cost via
+scratchpad/probe_result_button_fp.py (checks _find_result_button against
+the plain Quest list with no sweep in progress): the shared
+SWEEP_RESULT_BUTTON_REGION (700-1300 x-range, borrowed directly from
+story_sweep.py) reaches into this event's own Quest-list character-art
+panel on the left side of the screen, which false-positive-matched
+SWEEP_CONFIRM_CYAN even with no result dialog showing at all -- confirmed
+on both a wrong/finished event page and, more importantly, the actual
+correct current event's own plain list. This meant _watch_sweep_result's
+reaction kept "finding" a result button and clicking it after the real
+one had already been fully dismissed, so the "modal closed, no result
+button" end condition could never match. Fixed with a new, event_sweep-
+only EVENT_SWEEP_RESULT_BUTTON_REGION (x narrowed to 1000-1300, excluding
+the character-art panel while still comfortably covering the real
+buttons' known x~1150 position) -- confirmed via the same saved
+false-positive screenshot returning no match afterward. Deliberately NOT
+changed in the shared SWEEP_RESULT_BUTTON_REGION story_sweep.py also uses,
+per this file's own established pattern of giving event_sweep its own
+constant rather than coupling the two tasks' config together whenever
+their actual on-screen content differs (see EVENT_STAGE_MODAL_PROBE's
+comment for the earlier instance of the same reasoning). Not yet
+re-confirmed against a fresh real bulk sweep (that day's AP was reduced to
+14/240 by the sweep that surfaced this, too low to force another MAX
+sweep) -- the fix is validated against the actual recorded false-positive
+screenshot and the same live code path, just not a full new live sweep.

 **Status**: the wrong-page-looping bug the user reported twice is now considered definitively fixed, confirmed via two independent real live sweeps in this follow-up alone (three total across the whole Phase 14 investigation). The `_watch_sweep_result` fix is well-reasoned and low-risk (outcome-logging correctness only; the actual sweep behavior was already safe even without it) but awaits live reconfirmation once AP regenerates.
 
+#### Phase 14 follow-up #6: stage 08/09 OCR misread (the flagged non-blocking gap, now actually hit) + the real `_watch_sweep_result` root cause
+
+**Reported 2026-07-11**: the daily rotation picked stage 9 for the first time since this task existed — exactly the previously-flagged-but-never-hit "stage-list rows for stages 08/09 consistently misread by OCR" gap. Real log: rows 366/538 ("08"/"09") read `None` on the first (wrong-page) attempt, then `'2'` and `None` respectively on the second (correct-page) attempt, while rows 710/883/1055 ("10"/"11"/"12") read correctly — confirmed NOT a navigation/timing bug this time.
+
+**Root cause** (isolated with `scratchpad/probe_event_stage_ocr.py` and `probe_ocr_psm_sweep.py`, run directly against a live screenshot with no game interaction needed after capture): the crop and its thresholded/upscaled version both looked completely clean by eye, but tesseract's segmentation consistently misreads "08" as "2" and drops/mangles "09" across every psm mode tried. `scratchpad/probe_ocr_fix_08_09.py` isolated why: the crop is edge-to-edge with no whitespace margin around the glyph pair, and adding a plain white border around the upscaled image before OCR fixed both digits to their exact correct values at every psm mode, without affecting the already-working "10". **Fix**: new `detector.read_int_bordered` (same pipeline as `read_int`, plus `cv2.copyMakeBorder`), used for all `EVENT_STAGE_ROW_Y` reads. Kept as its own function rather than changed in the shared `read_int`/`_ocr_crop`, since no other current OCR read in this project has this specific tight-crop shape.
+
+**Confirmed live**: ran `event_sweep` for real. `row @ 366: read '8'`, `row @ 538: read '9'` — stage 9 found, modal opened, sweep confirmed and executed. AP 233/240 → 14/240, credits +5,892, screenshot-confirmed safe return home. The originally reported bug is fixed.
+
+**Bonus finding**: the same run again logged `unrecognized_state` instead of `swept`, despite the sweep genuinely succeeding — proving follow-up #5's `clicked_any`-gate fix, while a real improvement, was not the whole story. Diagnosed at zero AP cost via `scratchpad/probe_result_button_fp.py` (checks `_find_result_button` against the plain Quest list with no sweep in progress, no AP needed to reproduce): the shared `SWEEP_RESULT_BUTTON_REGION` (x: 700–1300, borrowed directly from `story_sweep.py`) reaches into this event's own Quest-list character-art panel on the left side of the screen, which false-positive-matches `SWEEP_CONFIRM_CYAN` even with no result dialog showing at all — confirmed on both a wrong/finished event page and, more importantly, the actual correct event's own plain list. This meant `_watch_sweep_result`'s reaction kept "finding" a result button and clicking it after the real one had already been dismissed, so its "modal closed, no result button" end condition could never match. **Fix**: new `config.EVENT_SWEEP_RESULT_BUTTON_REGION` (x narrowed to 1000–1300, excluding the character-art panel while still comfortably covering the real buttons' known x≈1150 position), used only by `event_sweep.py`'s `_find_result_button` — deliberately not changed in the shared region `story_sweep.py` also uses, matching this task's established pattern of giving event_sweep its own constant whenever the two tasks' actual on-screen content differs. **Confirmed live** (zero AP): re-ran the same false-positive probe against the deployed fix on the real correct-event Quest list — `_find_result_button` now correctly returns `None` where it previously returned a false match. Not yet re-confirmed against a fresh full real sweep end-to-end, since that day's AP was down to 14/240 (too low for another MAX sweep) — the fix is validated against the actual live false-positive scenario and the real code path, just not a brand-new full sweep cycle.
+
+**Status**: both bugs fixed. The originally reported bug (stage 9 unreadable) is fully confirmed via a real successful live sweep. The `_watch_sweep_result` mislabeling's real root cause is now understood and fixed (previous fix attempt addressed a real but secondary issue); confirmed against the actual live false-positive condition, awaiting one more full live sweep to confirm the outcome log itself reads `"swept"` next time AP allows.
