+# The Android shell under `android/` ships from the same tag the desktop line
+# publishes, and lands on the same release page.
+#
+# It is a separate workflow rather than a job inside release-studio.yml for two
+# reasons. The toolchains share nothing — Go, the Android SDK, a Gradle wrapper —
+# so a runner carrying both would install three toolchains to build one artifact.
+# And `signing-contract` pins which workflows may reach the SignPath credentials;
+# this one never touches them, and keeping it out of that graph is what keeps the
+# fingerprint stable.
+#
+# A failure here does not hold back the desktop release: the two are independent
+# by construction, and an APK is worth less than the desktop builds it sits

+## Auditing a batch
+
+`-batch DIR` writes two files from a suite run: `results.jsonl` (one row per
+attempt — the raw record every figure is computed from) and `batch.json`
+(manifest v1). `-mode audit -batch DIR` re-derives the report's headline figures
+from `results.jsonl`, prints the manifest's claim beside the recomputed value,
+and exits non-zero naming any figure that moved. It also refuses a batch whose
+manifest is missing, records no commit, or whose rows are truncated.
+
+This is an **aggregation audit, not a replay**: it proves the published figures
+follow from the retained rows. It does not re-execute the model, tools or
+environment, and cannot show the experiment would reproduce. A real replay would
+need the commit, a corpus fingerprint, the model and provider configuration, the
+seed, the flags, the raw results and the runtime version; it is not implemented.
+
+`schema_version` is top level. The rest is three groups:
+
+| Group | Fields | Answers |
+| --- | --- | --- |
+| `over` | `command.mode` and `command.axes` (every flag that changes what a figure means; paths omitted); `tasks.count` and `tasks.digest` (sha256 over sorted, NUL-separated task ids — the corpus identity, never the task text); `filters`; `denominator` (`unit`, `definition`, `value`) | what the figures are over |
+| `producer` | `commit` (or an explicit `unknown`, never a guess), `commit_source`, `dirty`, `model`, `provider`, `seed`, `started_at`, `finished_at`, `harness_version`, `go_version` | which run produced them |
+| `trust` | `results_sha256`, `claimed` (the headline figures), `ledger`, `retention` | why they can still be checked |
+
+The ledger accounts for every planned run, and the audit checks that the counts
+form a funnel (`scored ≤ completed ≤ attempted`, `failed ≤ scored`,
+`scored = pass1 + failed`, `rows = attempted + skipped`). A row count is never a
+denominator: `denominator.value` is a count of scored tasks, and `rows` is
+published only to show what was retained.
+
+| Count | Meaning |
+| --- | --- |
+| `planned` | graded runs the batch set out to attempt: filtered tasks × trials |
+| `attempted` | retained rows for runs that started (skipped rows are not attempts) |
+| `completed` | attempts that ended and left a row; this harness writes a row only after an attempt ends, so it equals `attempted` and the equality is checked, not assumed |
+| `scored` | completed first attempts of solvable, non-skipped tasks — the pass@1 denominator |
+| `failed` | scored attempts the grader did not pass |
+| `unmeasured` | attempts whose cost and tokens are unknown because no metrics landed; kept out of spend totals, never counted as zero |
+| `excluded` | rows kept out of the accuracy denominator: skipped, `no_solution`, and retry entries |
+
+Spend and cache fields are omitted from `claimed` when nothing was measured, so
+an absent figure reads as unknown rather than as a measured zero. `seed` is
+omitted for the same reason: the harness does not set a sampling seed.
+`results_sha256` covers the values and the presence of every row; line endings,
+indentation and key order are normalised away because none of them is evidence,
+while number spelling is kept (a rewritten `1` is not `1.0`).
+A successful audit records the verifier version (`audit.verifier_version`) and
+the digest it checked in `batch.json`, so a re-verification can tell which code
+checked the batch.
+
+`results.jsonl` is retained unredacted beside the manifest — task prompts and
+agent notes included — and is not public. The manifest itself carries a task-id
+digest, no prompt text, no absolute paths, no endpoints or keys and no model
+output. A claim whose rows are gone cannot be audited: there is nothing to
+recompute from, and this tool will not certify it.
+

+## Messages sent during a run
+
+**Settings → Appearance → Keyboard shortcuts → Messages sent while running** chooses the default:
+
+- **Steer at the next tool boundary** (default) adds guidance to the current run.
+- **Send after the whole run** queues a new turn until the active run finishes.
+
+The choice is local to this device's browser profile, applies across projects,
+and survives reloads. It does not change idle sends or messages already queued.
+Skill invocations continue to use follow-up turns.
+
+The queue still supports hold/resume, editing, and taking a message back into
+the composer. **Send now** overrides the wait for a selected message by stopping
+the current response and starting that message as a new turn; it is unavailable
+while the queue is held.
+
+Guidance not delivered before a run ends still becomes a follow-up through the
+kernel's existing queue.
+
+## Global show/hide shortcut
+
+In the desktop shell, **Settings → Appearance → Global show / hide shortcut**
+offers one opt-in binding, disabled by default.
+
+1. Click **Record shortcut**, then press a modifier and key combination.
+   Escape cancels recording.
+2. Review the platform-native label, then **Apply shortcut** to register it.
+3. **Clear shortcut** disables it immediately.
+
+You can also edit the Electron accelerator directly (up to 128 characters).
+The shell requires Control, Command, Alt or Super, even through IPC or when
+restored from disk. Shift may accompany one of them but cannot qualify alone.
+
+The shortcut hides a focused Studio window; otherwise it restores, shows and
+focuses the existing window. It does not change in-app shortcuts or tray settings.
+
+The primary Electron instance owns the binding and stores it in its local shell
+profile. Changes apply immediately; invalid or unavailable bindings leave the
+previous saved and registered binding intact.
+
+Startup registration failures are shown in settings rather than reported as
+success. An unavailable binding may be occupied, reserved by the OS, denied
+permission, or unsupported by the desktop.
+
+Native Wayland environments may not support registration with this Electron
+backend; no portal authorization or cross-platform success is implied.
+
+The binding exists only while Studio is running. It cannot launch a stopped
+application and no external daemon is installed. Browser and network viewers
+cannot configure a remote machine's global shortcut.

+The Linux/X11 and macOS shortcut smoke drives the real Studio window, chord

 # Reasonix Studio frontend

+## Feedback contact
+
+- Studio prefills new reports with the contact value from the last successful
+  submission, stored in this device's local browser storage.
+- The field stays editable; submitting it empty clears the remembered value.
+  Failed submissions do not replace it.
+- An unsent draft takes precedence while the page is open.
+- No feedback body or screenshots are persisted by this preference.
+
+## Pane workspace metadata
+
+- Each pane owns one workspace-metadata read after its initial status settles.
+  Chrome and the composer's workspace chip consume that same result.
+- A failed initial status still allows the read using the runtime's known root;
+  history loads independently of both status and workspace metadata.
+- Changing the pane's port or directory reads again and discards superseded
+  responses. Focusing an already-open pane reuses its own result.
+- Opening the workspace chooser still refreshes its branches and worktree
+  sources; it does not issue another workspace-metadata read.

+  sampling only after `setViewportSize` returns can miss the stale-mirror frame.
+  It selects `/init`, types the draft, then visits
+  1440 → 960 → 640 → 420 → 1440px at each zoom.
+- The native-scrollbar case requires a space-consuming gutter, not an exact
+  pixel width; overlay-scrollbar browsers explicitly skip that case.
+- `?panes=N` seeds the mock hub's shared runtime/session book. Tree rows and open
+  panes must agree on both transcript path and runtime ID.
+- `rail-toggle-panes.mjs` selects two existing sessions by path, verifies that the
+  original transcript DOM node is hidden and restored, and checks scroll retention
+  while new output arrives in the background.
+- The same guard checks that a neighbouring pane following the latest output
+  continues to do so. `RAIL_TOGGLE_SHOTS` saves its before/hidden/returned views.
