A raw `adb shell input tap` took no lease, so one session's tap landed in
another session's app (2026-09-25). python_pkg.phone_guard classifies every
adb call in a Bash command and, as the Claude Code PreToolUse hook, takes
the matching phone_lease (one app / real screen / whole phone) or exits 2:
key/text input without -d, input on another session's virtual display, or
a lease still held elsewhere after 40 s.
android_ui gains --display self|<id>: it drives only this session's
phone_vd display under that app's lease, and every input carries -d.
uiautomator sees display 0 only, so virtual-display trees come from a tiny
instrumentation APK (A11yDump.java) built from source without Gradle.
Prunes the oldest evidence artifact to stay under the 60-file cap.

Two sessions driving the same phone interleave their taps: on 2026-09-20 a
tap meant for the workout sandbox opened another session's manga reader,
twice. The lease is a flock-guarded JSON file per serial under
~/.cache/phone-lease/, owned by the nearest ancestor `claude` process (one per
session), refreshed on every android_ui call and expiring 180 s after the
last one, so a quiet session frees the phone without anyone remembering to.
A foreign fresh lease makes a call wait up to 60 s, then exit 3 naming the
holder and pointing at the alternatives (the phone's virtual display, the
headless emulator) instead of inviting a retry loop. phone_deploy.sh takes
the same lease (exit 40).
The oldest evidence artifact is pruned to stay under the 60-file cap; it
remains in history.

Also bumps the 16 meta/requirements pins the freshness gate flagged
(anthropic 1.5.0, numpy 2.5.3, pytest-randomly 5, flake8-bugbear 26.9.9,
ruff 0.16.7, pyright 1.1.414, selenium 4.49.0, hypothesis 6.168.0, lxml
6.1.3, pipdeptree 4.2.5, the two types-* stubs) and Flutter 3.47.3 in
meta/.fvmrc. One test still expected the pre-move ~/mcp-servers path.
The pre-commit hook fed .zsh files to shfmt and shellcheck, neither of
which parses zsh (SC2148/SC1071), so no zsh file could be committed since
the hook was tightened on 2026-08-22; those now get `zsh -n` instead. The
hook's own shfmt pass also staged its reformat of 8 shell files.
CI_GREEN_SKIP because main is red on exactly the dependency-freshness
finding this commit fixes, which is the documented use of that flag.

A Flutter/Material TextField publishes its label as `hint` and leaves text
and content-desc empty, so every field on such a form arrived as an
anonymous EditText. The workout app's manual-workout form is nine of them:
the only way to fill it was by screen position, which is precisely the
mis-tap-writes-the-wrong-field failure this tool exists to prevent.
`hint` ranks below text and content-desc but above resource-id. Material
clears the hint once content arrives, so a filled field still answers to its
real text and a caller can tell an empty field from a completed one.
The app-side alternative does not work and is documented as a trap: wrapping
the field in Semantics(label:) emits a second labelled node at the same rect,
and MergeSemantics collapses them by dropping the hint from Android's tree,
which leaves the form MORE anonymous than before. Widget tests cannot catch
that -- they assert on Flutter's SemanticsNode while this tool reads
Android's AccessibilityNodeInfo, so nine of them passed green on the build
whose on-device labels had just gone empty.

Shared across every repo with an Android surface (screen-locker's workout_app,
todo, dufs-cloud/app). Works against a plain release APK on a physical device
over adb — no root, no emulator, no Flutter debug connection, no app changes.
Driving an app by tapping pixel positions read off a screenshot fails in ways
that look like success. All observed in one session (2026-08-10) verifying
workout_app's Firebase restore:
* A tap aimed at a password field landed with the field unfocused. The typed
password went nowhere and NOTHING errored — the next screenshot just showed
an empty box. type_into/type_into_field now re-read the field and raise.
* Opening the soft keyboard moved a field from y=1572 to y=1319, so a
coordinate captured one step earlier was already wrong. Every action
re-resolves the element immediately before acting.
* A widget behind the keyboard reports its LAID-OUT position (1549) not its
real one (1939) — a 390px error that taps a letter key and reports success.
keyboard_is_up() distinguishes "absent" from "behind the keyboard", and tap
closes the keyboard first.
* KEYCODE_BACK is a route pop in Flutter, not a keyboard dismiss: it navigated
out of Settings and discarded typed credentials, twice. dismiss_keyboard
tries ESCAPE then BACK and verifies via dumpsys input_method.
* `input text` inserts at the cursor, so typing over a filled field produced
"canary@example.com321krzychu@gmail.com". Fields are cleared first.
* uiautomator returns ONLY the focused EditText nodes while a Flutter text
field has focus, and stays that way across retries — so a naive retry loop
never converges. Partial trees are retried and the best result kept.
* An EMPTY EditText has no text, content-desc or resource-id, so a
"must be labelled" filter drops the very field you need to fill in. Editable
nodes are kept regardless and addressable by position.
Ambiguity is an error rather than a silent first-match: `tap "Back"` correctly
refuses when "OFFLINE BACKUP" is also on screen.
Its own test suite caught a real bug in _escape: backslash sat inside the
escape loop, so "&" became "\\&" and a password containing shell
metacharacters would have been typed wrong.
