This project's job is to make that same automation logic work against the real JP client running under Proton on Linux instead — porting the reference's decision logic, navigation, and state-detection approach (including its use of OCR) as faithfully as practical, and replacing only the parts that are genuinely Android-specific (ADB/uiautomator2 input and UI-object-tree queries) with local desktop equivalents (xdotool, scrot, OpenCV, OCR). Inventing a different, simpler approach to avoid porting a piece of reference logic (most notably OCR — see below) is a deviation from that goal, not a shortcut toward it.

 The automation backend is local desktop control:
 
 - `xdotool` for mouse/keyboard/window control

 - Python/OpenCV for image matching and color/template detection

 ### OCR policy
 
-OCR is **not** an Android-specific concern — the reference's OCR-driven region/stage-name/currency matching runs against a screenshot and would work identically against a `scrot` capture on this backend. Only the reference's *input* (ADB/uiautomator2 taps) is Android-specific.
+OCR is **not** an Android-specific concern. The reference's OCR-driven region, stage-name, and currency matching runs against a screenshot and can be ported to this backend using `scrot` captures. Only the reference's input mechanism is Android-specific.
 
-Two features (Stamina/AP mission claim, Normal/Hard story AP sweep) were originally built without OCR by substituting ad hoc pixel-probes, fixed coordinates, or randomized selection for the reference's OCR-driven navigation. For story sweep, that substitution produced more real bugs during live testing than porting the reference's actual approach would have — a wrong modal-open probe, an unverified button click that silently under-spent AP, a modal that doesn't close on Escape, and a latent hazard where a mistimed keypress could have started a real battle (see `plan.md` Phase 9's retrospective for the full writeup). None of those bugs would exist if the reference's deterministic, OCR-based stage targeting had been ported instead of replaced with a heuristic guess. **This has since been fixed** — `story_sweep.py` now ports the reference's actual OCR-based region/stage targeting (see `plan.md` Phase 10) — but the retrospective stays here as the concrete, lived reason for the policy below, not a description of the current state of that task.

 Examples:

 - debug screenshots
 - annotated match results
+- temporary Python probes

-Do not use `/tmp` or `/private/tmp` unless there is a strong reason.
+Create it if missing:
+

+mkdir -p scratchpad
+```
+
+Do **not** use Claude Code's internal temporary directories such as:
+
+```text
+/private/tmp/claude-*
+/tmp/claude-*
+```
+
+Do **not** run probes from `/private/tmp/claude-*` or write temporary scripts there. These paths are outside the repository and often trigger extra permission prompts, interrupting the development flow.
+
+When a temporary Python probe is needed, write it into `scratchpad/` first, then run it from the repository root.
+
+Preferred pattern:

+```bash

+```
+
+Also avoid large multiline `python3 -c "..."` commands when they contain comments or complex quoting. Prefer a temporary script under `scratchpad/` because it is easier to inspect, rerun, and keep within workspace permissions.
 
 `screenshots/` contains human reference captures. They are useful for calibration and documentation, but they are not necessarily automated test fixtures.
 
 `assets/` contains local template images. These should be captured from the local game setup where possible.
 
+## Temporary probe policy
+
+Temporary probes are allowed, but they must be workspace-local.
+
+For non-trivial investigation, use:
+
+```text
+scratchpad/<short_descriptive_name>.py
+```
+
+Examples:
+
+```text
+scratchpad/probe_shop_checkbox.py
+scratchpad/probe_cafe_income.py
+scratchpad/probe_story_modal.py
+scratchpad/probe_ocr_region.py
+```
+
+A temporary probe should:
+
+- run from the repository root
+- read inputs from `scratchpad/`, `screenshots/`, or `assets/`
+- write outputs to `scratchpad/`
+- avoid `/tmp`, `/private/tmp`, and Claude Code internal paths
+- avoid relying on absolute `/private/tmp/claude-*` paths
+- be deletable once the investigation is complete
+
+Prefer:
+
+```bash
+python3 scratchpad/probe_shop_checkbox.py
+```
+
+Do not prefer:
+
+```bash
+python3 -c "large multiline script..."
+```
+
+For very small one-liners, `python3 -c` is acceptable only when it does not require changing directories into `/private/tmp/claude-*`.
+
 ## Testing and checks
 
 Because the game only runs on `nik-gpu`, local macOS testing is limited.
 
 Before deploying, run static/syntax checks locally:
 
-```
+```bash
 bash -n ba_dailies.sh
 python3 -m py_compile ba_daily.py
 python3 -m py_compile ba_auto/*.py
 python3 -m py_compile ba_auto/tasks/*.py
 ```
 
+For temporary investigation scripts, use:
+
+```bash
+python3 scratchpad/<script_name>.py
+```
+
+Do not run temporary investigation scripts from Claude Code's internal `/private/tmp/claude-*` workspace.
+
 On `nik-gpu`, run real integration tests against the live game.
 
 Example:
 
-```
-ssh nik-gpu "~/ba_dailies.sh cafe"
+```bash
+ssh nik-gpu "~/repo/ba-auto-daily/ba_dailies.sh cafe"

-- Live testing found both the mailbox-icon and cafe-icon fixed coordinates were flaky (missed the first click, worked on retry) and that neither task verified anything before proceeding, so a missed click cascaded into blind actions and could reach an unverified Escape press on the home screen — which triggers Blue Archive's own "exit the game?" confirmation. See `plan.md` Phases 5–6 for the full writeup. This is the concrete reason every task now verifies state before acting rather than trusting fixed coordinates or a single click blindly
-- Rank-up popups mid-pat-loop are now handled: a pat that crosses an affection-rank threshold shows a full-screen "絆ランクアップ!" cutscene with no cafe header at all, which `find_cafe_sparkle()` can never recognize (it's nothing like the sparkle template) — the loop used to just spin uselessly against it for the rest of the room's click budget. `cafe.py`'s `_dismiss_rank_up_if_shown()` reuses the existing `navigation.is_on_subscreen` header-brightness probe (confirmed against `screenshots/cafe/student/01-02`: it reads r<200 during the cutscene vs. r>200 on the normal cafe screen) to detect it and press Enter until it clears, porting the reference's own `to_cafe()`-navigation handling of `relationship_rank_up` (`module/cafe_reward.py`). Not yet live-confirmed against a real rank-up trigger (it's semi-random, tied to hitting an affection threshold) — the fix is grounded in real captured screenshots, not a live end-to-end run; treat as implemented-but-unverified until one happens naturally during a real run

+`story_sweep.py` additionally has its own local modal probes and close logic because the stage-info modal is wide enough to break `is_modal_open`'s default probe point, and it does not close on Escape. See `plan.md` Phase 9.
+
+The story sweep modal renders at least two different internal layouts:
+
+- a plain one for the bonus `-A` stage
+- a taller tabbed one for regular numbered stages
+
+Their button coordinates differ. This was discovered live in Phase 10.
+
+Live testing found both the mailbox-icon and cafe-icon fixed coordinates were flaky. They missed the first click and worked on retry. Neither task originally verified state before proceeding, so a missed click cascaded into blind actions and could reach an unverified Escape press on the home screen, which triggers Blue Archive's own "exit the game?" confirmation.
+
+See `plan.md` Phases 5–6 for the full writeup. This is the concrete reason every task now verifies state before acting rather than trusting fixed coordinates or a single click blindly.
+
+Rank-up popups mid-pat-loop are now handled.
+
+A pat that crosses an affection-rank threshold shows a full-screen `絆ランクアップ!` cutscene with no cafe header. `find_cafe_sparkle()` can never recognize this because it is nothing like the sparkle template. The loop used to spin uselessly against it for the rest of the room's click budget.
+
+`cafe.py`'s `_dismiss_rank_up_if_shown()` reuses the existing `navigation.is_on_subscreen` header-brightness probe. This was confirmed against `screenshots/cafe/student/01-02`:
+
+- rank-up cutscene: header probe reads `r < 200`
+- normal cafe screen: header probe reads `r > 200`
+
+It presses Enter until the cutscene clears, porting the reference's own `to_cafe()` navigation handling of `relationship_rank_up` from `module/cafe_reward.py`.
+
+This is not yet live-confirmed against a real rank-up trigger. It is grounded in real captured screenshots, but treat it as implemented-but-unverified until one happens naturally during a real run.
+
+Not yet verified for cafe:
+
+- whether camera zoom/pan can drift over a long unattended run
+- the reference project zooms out before detecting
+- this project currently does not
+- testing did not reproduce a failure from skipping it
+- see `plan.md` Phase 6 "Not verified" list
