Problem

The window still runs each turn through claude -p and keeps chats in JSONL files. A crash or an update can cut a turn off, and the update gate does not know about it. This PR moves the window onto the sidecar's committed chats, imports the old chats once, and removes the claude -p runner.

Change

src/studio/StudioApp.tsx    chats from the sidecar's committed entries: chat.open, chat.send, chat.retry, chat.stop
                              drafts saved on pause and on leaving a screen, one save per screen at a time; a send names only a saved draft revision
src/studio/Waiting.tsx      the waiting banner names the fix (sign in, or go on), and asks a sign-in's questions
                            the chat shows the model its turn runs on
                            a readiness notice keeps Send off until sign-in, model, uv, and Python are there, and names the fix
                            a notice when macOS keeps Documents from the app, with Open Privacy settings and Try again
sidecar/src/methods.ts      setup.check (what the agent needs), legacy.import (retry), drafts.picture (pasted pictures kept in files)
sidecar/src/chat.ts         chat.send({ key, rev }) sends a stored draft revision: makes the start screen's project, moves the draft
                              by revision, copies its pictures, commits the message as draft-<rev> with the draft's removal (#205)
sidecar/src/store.ts        each draft carries a revision; a start screen revision makes one project and records the draft it moved
src-tauri/src/studio/quit.rs  a normal quit or window close waits for the window: 1.5 s for its first answer, then until it is done (60 s ceiling);
                              a draft the window could not save calls the quit off
sidecar/src/busy.ts         the update pass: held while any task works, given back while a turn only waits on a sign-in
src-tauri/src/sidecar.rs    the `busy` request takes or gives back the update gate's pass, per sidecar run
sidecar/src/legacy.ts       old .m3d/transcript.jsonl chats imported once, before the window connects, files kept
removed                     studio/turn.rs, studio/lean.rs, system_prompt.md, the studio plugin: the claude -p runner
kept                        slice, Keychain, file preview, reveal, open in Bambu Studio, the updater
formal-verify skill         UpdateRestart.tla models the sidecar's pass. sources.sha256 covers busy.ts, chat.ts, app.ts

Closes #205 and #206. Follow-ups that lose no draft: #207, #208, #209.

The cube job and the crash test, on aojdevmac-m5, e2e debug build of this branch at 5024e48 (5e390f3 adds Pullfrog's three window and reconcile fixes), driven by mac.ts with WebKit snapshots. The send waited for a sign-in with the fix named, went on after it, and sliced the cube:

The sidecar killed with SIGKILL during the second tool step. Rust started it again, the finished first step ran once, and the turn finished with Send back:

print/cube_P2S_PETG.3mf   (Metadata/plate_1.gcode, 427679 bytes, and Metadata/slice_info.config inside)
killing sidecar pid(s) 27476 with SIGKILL; sidecar after the kill: 27710
ops.log after the turn: step1, step2-start, step2-start, step2-done

The signed, notarized build of the final head, cca2035 (DMG sha256 c065f14009c4ed50b2ba6e42d4e9a544dac0daa97df2d4a105a8deaafa4502e1, signed by Developer ID 8A4Y276VK7), passed the release smoke on aojdevmac-m5. Gatekeeper accepts it as Notarized Developer ID. The sidecar runs as the app's child. A second sidecar on its store exits 75. The headless send makes its project and asks for the update pass. No sidecar is left after the app is killed. Both subscription sign-ins reach their first step.

The same DMG, installed on the Mac mini (app CDHash 18e9257fb4cfed03b6060a27755a18abacc95878, sidecar CDHash c6ba2ff5841413f93f6676567b103fb28aa8aed9), made a 20 mm calibration cube and sliced it in the signed app, driven by CuaDriver: print/cube_P2S_PETG.3mf, sha256 8f731f4ba77398574fc3164b72f5140dea9a802e0f03d75913e181077f4a597c, with Metadata/plate_1.gcode and slice_info.config inside. macOS showed its "damaged" prompt for that Mac's copy of Bambu Studio before the slice, and it was cancelled by hand (#210). The same DMG replaced ~/Applications/Materialize 3D Chat.app on the MacBook, with the same CDHashes, and its sidecar runs on the existing store.

The cube and crash runs in the e2e debug build above are from 5024e48.

Merge danger

Door: two-way. Revert this PR to undo it. The old chat files stay in place, and the import copies them.
Blast radius: high. Every chat a person sends now runs through the sidecar, and every update waits on its pass. A stuck pass would hold updates back. The gate tests, TLC, and the m5 runs prove the pass is given back, but the change reaches every person.

Walkthrough

The PR moves Studio chat execution and storage to the sidecar. It adds revisioned drafts, update-gate coordination, legacy chat import, readiness and sign-in flows, and quit-time draft flushing. The Studio UI now uses sidecar state and chat entries. The Rust Studio runner and bundled plugin are removed.

Changes: Sidecar Chat Runtime Migration

Layer / File(s)	Summary
Revisioned drafts and chat sending sidecar/src/protocol.ts, sidecar/src/store.ts, sidecar/src/chat.ts, sidecar/src/methods.ts, sidecar/test/*	Draft saves now return revisions. Sending uses a draft key and revision, creates or recovers a start-screen project, and avoids duplicate sends. Attachments are copied into project references, and newer drafts remain stored.
Update gate and quit flush sidecar/src/busy.ts, sidecar/src/agent.ts, sidecar/src/app.ts, src-tauri/src/sidecar.rs, src-tauri/src/studio/quit.rs, src-tauri/src/lib.rs, src-tauri/build.rs, src-tauri/capabilities/default.json, src/studio/api.ts, sidecar/test/*	The sidecar coordinates task and send activity with update passes. Sign-in waits park tasks and reacquire passes before continuing. Quit and window-close requests wait for a draft flush.
Legacy chat import sidecar/src/legacy.ts, sidecar/src/protocol.ts, sidecar/src/store.ts, sidecar/src/transcript.ts, sidecar/src/app.ts, sidecar/test/fixtures/legacy/*, sidecar/test/switch.test.ts	Legacy project records and transcripts are converted to imported entries and stored in conversations. The sidecar reports blocked imports and supports retry.
Studio UI and chat rendering src/studio/StudioApp.tsx, src/studio/Chat.tsx, src/studio/Waiting.tsx, src/studio/transcript.ts, src/studio/api.ts, src/studio/studio.css, src/studio/StudioApp.test.tsx, src/studio/transcript.test.ts	The UI uses sidecar state, sequenced chat updates, screen-specific draft persistence, readiness checks, sign-in prompts, and pasted-picture storage. Transcript rendering consumes stored chat entries and imported entries.
Retire the Rust Studio runner and plugin src-tauri/src/studio/*, src-tauri/resources/studio-plugin/*, src-tauri/tauri.conf.json, src-tauri/build.rs, src-tauri/capabilities/default.json, scripts/release/check-app-bundle.sh	The Rust Studio runner and project commands are removed. The plugin resources and bundle mapping are removed. The host registers quit-flush and privacy commands.
Verification and runtime documentation .agents/skills/formal-verify-materialize-3d/*, .agents/skills/verify-materialize-3d/features/studio.md, .github/workflows/formal-verification.yml	The formal model, checksum manifest, workflow coverage, and Studio runtime instructions now describe the sidecar runtime and update-gate behavior.

Merge Risk: Moderate · previous review 361b3

Resolve the draft-loss races and startup recovery gap before merging. Quitting during pending work can lose unsent content, and an early engine failure can leave saved projects inaccessible until the window restarts. Picture handling also has several bounded correctness and resource-retention issues.

Full details: Title check

Explanation

The title names the two main changes: studio chats now run on the sidecar's committed chats, and the claude -p runner is removed. The raw summary confirms both: studio chat storage and sends move to the sidecar, and the Claude CLI/turn runner files (turn.rs, lean.rs, system_prompt.md, the fabricate skill) are deleted. The title is long, at 16 words and 97 characters, and it uses a conventional commit prefix. It is specific enough for a reviewer scanning history to see the primary change.

Full details: Docstring Coverage

Explanation

Docstring coverage is 84.62% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 39 functions across 30 files.

Test the gate with two active projects.

Start a held run tool in one project and park Astra on sign-in in another. Assert that the pass stays held until the run tool finishes, then is released. The current tests would not catch a regression that releases the pass while the run tool is active.

Update the test beginning with “gives the pass back while Astra waits on a

Astra on sign-in in the other, then assert the gate pass remains held while the
run tool is active and is released only after it finishes. Reuse the existing

during decrements the send count and synchronizes against the last delivered task graph, not necessarily the graph produced by the completed commit. If graph delivery lags commit completion, this can release the pass between submitting a turn and observing its live tasks.

An updater can close the gate during the handoff, leaving the newly submitted turn running without a pass or cutting it off on restart.

This can occur when: A first send commits while #graph is still empty, and its task-graph notification arrives after the finally synchronization.

This is a verification gap: the updated model describes the sidecar lifecycle, but its actions still model acquisition and work start as one step and omit task-graph delivery and the send-to-task handoff. A Busy implementation that releases on a stale empty graph can therefore retain the recorded passing verdict.

The formal check cannot detect an update cutting off the newly submitted work, despite being documented as checking this sidecar lifecycle.

This can occur when: A send commits before Busy receives its live-task graph, allowing a false busy notification before task observation.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

Submitting a sign-in answer dismisses its prompt before auth.answer succeeds, and rejection only displays an error rather than restoring the unanswered question.

The login remains waiting for input, but the window no longer offers the question or an answer retry.

This can occur when: An answer submission fails before the login service consumes it, for example because forwarding the command fails transiently.

Review comments at @sidecar/src/legacy.ts:
- Line 48: Update the event handling in the switch on event.type to preserve
m3d_files entries during legacy transcript import, so migrated conversations
render their file cards and preview actions while retaining the files in the
Files tab. Also restore the missing file entries for chats that have already
been imported, using the existing migration and persistence mechanisms;
establish how imported chats are identified and updated before choosing the
restoration path.
- Line 57: Update the legacy importer’s tool record construction around `tool`
to determine whether the transcript contains a result for each tool; mark tools
without a recorded result as stopped or unknown before import, and preserve the
successful status only when a result exists.
- Around line 86-87: Handle errors in the legacy project discovery flow around
readdirSync: catch failures listing the projects directory, report the error
through the existing mechanism, and return an empty discovery result so startup
can continue and the import can be retried later.
- Line 47: Validate `event.message.content` before processing it, accepting only
the supported string or block-array forms and rejecting object content or arrays
containing null blocks; handle malformed events locally so they do not cause the
import to discard otherwise readable project history.

Review comments at @src-tauri/src/sidecar.rs:
- Around line 576-577: Update the interaction between once_per_operation and
with_own_pass so temporary pass-gate refusals are not retained in the operation
cache and can be retried after an update fails. Preserve deduplication for
successful per-operation slices.
- Around line 279-288: Update the login PATH reader around `said.recv_timeout`
and the `child.try_wait` loop so it can accept PATH as soon as the shell prints
it, without waiting for stdout EOF from descendants. When the shell exits,
ensure the reader is stopped and retained descendants holding stdout are handled
without delaying the lookup until the deadline.
- Line 413: Keep the update hold active in the sidecar run loop when stdout
reading fails; release it through sidecar.run_ended() only after the sidecar
process has exited, ensuring its current turn work is not interrupted by an
update.
- Around line 576-578: Update the host-slice lifecycle around once_per_operation
and the spawn_blocking call in with_own_pass to track active slices and ensure
shutdown waits for them to finish or stops them before exit. Include completion
or cancellation of staging cleanup so a slice cannot leave a staged result
unpublished.

Review comments at @src-tauri/src/studio/mod.rs:
- Around line 12-14: Update the legacy project import flow associated with
META_DIR so projects without a transcript are imported with an empty
conversation instead of being skipped. Preserve the project metadata so the
project remains available to open after upgrade.

Review comments at @src/studio/StudioApp.tsx:
- Line 153: Update the draft-opening flow in StudioApp to restore
project-relative attachments in the composer, then preserve the composer’s
attachments when calling drafts.set instead of replacing them with an empty
list; ensure subsequent sends retain the restored pictures.
- Line 234: Update the buffered-event reduction around setView in StudioApp so
events are ordered against the opened snapshot and older state cannot overwrite
newer state. Preserve the correcting stopped state even when its event arrives
later because of a slow Keychain read, preventing stale running state from
keeping Working and Stop visible or blocking Send.
- Around line 289-293: Update the retry flow around `again` so switching
projects preserves the pending image state and its request ID; do not rely on
attachment object identity to recognize the same image after reattachment.
Ensure retrying the same message and image reuses the original request ID and
does not import or submit it again.
- Around line 307-310: On successful send, cancel a queued draft save matching
the sent message: if unsaved.current targets the same id and its text matches
message after trimming, clear its timer and reset unsaved.current. Preserve the
existing pending and drafts cleanup, and leave queued saves for other messages
unchanged.
- Around line 128-131: Update the sign-in prompt state in StudioApp so pending
prompts are retained by provider instead of in a single shared value. Store each
`ask` event under its provider and, when handling a `done` event, clear only
that event’s provider prompt so another provider’s question remains available
for the user to answer.
- Line 98: Update the project state handling around setProjects(state.projects)
to reconcile the incoming snapshot with projects created locally during startup,
deduplicating by project ID so a stale response does not remove newly created
projects from the sidebar.
- Around line 305-307: After the successful chat.send call in the send flow,
clear the send error for project id while preserving errors for other projects;
keep the existing pending and draft updates intact.

Review comments at @src/studio/transcript.ts:
- Around line 70-72: Update the transcript recovery flow that creates ToolItem
entries and populates tools so result-less calls known to have been stopped
render with a terminal stopped status rather than appearing to run; preserve the
existing handling for calls that have results.
- Around line 41-44: The written function currently records paths only for
write, edit, and slice; extend its file-detection behavior to capture files
produced by run and Astra so turn outputs retain their preview actions.
Establish how those tools expose changed or created file paths and reuse that
information without assuming undocumented argument fields.

finishes. Reuse the existing sidecar and gate assertions, and use the available
test fixture behavior for the held run tool.

Review loop stopped under land-pr's convergence rule. Message identity for a send went through five review rounds and one redesign, which spun too. The root cause and all 12 cases are in #205: the window and the sidecar both own the draft and the outgoing message. The round's commits (0aa8402..b35114b, local) are not pushed. The four Pullfrog P2 threads stay open until the next round, which builds #205's design, lands.

269-270: Minor · Potential issue · Heavy lift

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

The new send path depends on an atomic ownership handoff from Busy.during to the harness task watcher. The supplied during implementation decrements its send count as soon as the commit returns; if task publication has not reached the watcher then, its subsequent #follow() may incorrectly release the update pass while the committed turn is starting.

The host could admit an update while sidecar turn work is running, violating the update gate's exclusion contract.

This can occur when: A turn submission commits before the Busy task watcher observes the newly active run, and an update attempts to install during that interval.

Review comments at @sidecar/src/app.ts:
- Around line 109-110: Update the cleanup-retention logic around `kept` and
`named` to exclude attachments from committed submissions once the project copy
exists, while preserving their replay identity and retaining pictures for
interrupted sends. Establish how commit status and project-copy availability are
represented before changing the filter; keep uncommitted or incomplete sends in
retention.

Review comments at @sidecar/src/chat.ts:
- Around line 108-111: Update the name collision check around names.has(name) to
compare names case-insensitively, including candidates already reserved and
existing destinations, so differently cased picture names receive deterministic
suffixes instead of being skipped. Preserve the existing suffix retry behavior
and destination-existence check.
- Around line 113-118: Update the legacy draft migration used by copyPictures so
project-relative picture paths resolve against the draft’s project directory
rather than the sidecar’s working directory. Preserve already-valid absolute
paths and ensure migrated paths point to the existing project pictures before
copyPictures validates and copies them.
- Around line 116-118: Update temporary-name construction for `part` near
`copyFileSync` so its component stays within the filesystem limit even for the
longest valid picture name. Preserve the existing cleanup and `COPYFILE_EXCL`
retry behavior.
- Around line 116-119: Update the attachment staging block that builds part and
target so each temporary path is reserved and cannot match any attachment
destination in the draft; do not remove or overwrite a destination while
preparing another attachment.
- Around line 255-266: Update the START handling around store.startProject(rev)
so an edited retry reuses the first unsubmitted project instead of creating
another project when the draft revision changes. Identify the existing project
associated with the failed initial send, preserve its association with the
updated draft, and keep the submissionByRequest check and normal new-project
behavior intact.

Review comments at @src/studio/StudioApp.tsx:
- Around line 323-327: Update the quit flow around the screens.current iteration

- Around line 432-433: Update the send-success cleanup around `outgoing` and
`next` in `StudioApp` to track attachment selections separately from their
paths, so it removes only the specific selections included in the sent draft.
Preserve a picture re-added while the send is pending in both the composer and
saved draft.
- Around line 298-304: Track the pending picture-import promise started by the
paste handler in StudioApp and await it before flushing drafts during quit. Keep
the wait within the existing quit timeout, and preserve the current import and
flush behavior once imports complete.
- Line 419: Update the Send eligibility guard in the StudioApp component so
sending remains disabled until the selected project’s chat has loaded and its
running state is known. Preserve the existing checks for empty drafts,
in-progress sends, active turns, and readiness; use the chat-loading state
already available in the component.
- Line 419: Update the readiness-check flow in StudioApp so asynchronous results
only update readiness state when they belong to the latest check. Prevent older
checks from restoring a stale login notice or disabling Send, while preserving
the existing `notReady` guard in the send condition.
- Around line 323-328: Update the quit flow around `screens.current` to wait for
every screen’s save and `flush` operation to settle before acknowledging quit.
Replace the fail-fast waiting behavior with an all-settled wait, preserving the
existing per-screen save-then-flush sequence so a failure in one screen cannot
allow shutdown to interrupt another screen’s pending flush.
- Around line 178-185: Update the state initialization flow around takeState so
it retries the initial state.get after the engine recovers if the first request
failed or never returned. Reapply the recovered projects and drafts through
takeState’s existing merge behavior, preserving drafts already changed in the

that no longer belong to a draft, using the entries in previews.current.
Preserve previews for pictures that remain in drafts, and do not release URLs

- Around line 182-185: Update the retry sequence in this test to remove the
source picture referenced by photo before creating the go file and calling send
again. Keep the retry and answered flow unchanged so it verifies send works from
the existing copies when the source is gone.

Review comments at @src/studio/StudioApp.test.tsx:
- Around line 537-541: Update the navigation test around the `shown` snapshot to
wait until the mock store contains the sent picture before clicking Project A or
Project B. Keep the existing navigation and draft-restoration assertions,
ensuring they run only after persistence is confirmed.

@pullfrog please review the new head, 361b3c5. The run at 00:19 UTC failed on the OpenAI usage limit before it reviewed anything. This head carries the one-owner draft send from #205, which replaces the window-side draft code your last review of 47918da commented on.

Important

One new draft race remains: Send can submit and clear text typed after the click when an autosave was already pending.

Reviewed changes Reviewed the delta from the previous Pullfrog review at 0aa8402 through 361b3c5, including #205's replacement of the window-owned send identity.

• Moved send ownership into the sidecar. chat.send({ key, rev }) resolves the stored draft, creates or recovers its first project, copies pictures, and deduplicates submissions by revision.
• Serialized composer persistence. Replaced window-generated request IDs and picture imports with per-screen drafts, completed-save revisions, and one in-flight save per screen.
• Preserved interrupted first sends. Recorded the moved draft alongside its project and retained its pictures during startup cleanup.
• Separated import refreshes from drafts. Limited import-retry snapshots to project and folder-access state.
• Bounded readiness checks. Made toolchain probes asynchronous with deadlines and added ~/.local/bin to executable discovery.

Validation: static tracing of the complete incremental diff and its regression tests. Exact-head Linux and macOS build gates and formal verification are green. Local tests were not run because the required testing-doctrine fetch returned gh: Not Found (HTTP 404); the inline race is source-traced, not dynamically reproduced. Existing Pullfrog threads are already resolved; the explicitly deferred limits in #206 and #207 are not repeated here.

✅ No new issues beyond the explicitly tracked follow-ups.

Reviewed changes Reviewed 05144bd since the previous Pullfrog review at 361b3c5.

• Captured sends at click. Passed the selected draft through pending autosaves, preserving text typed afterward as the next draft.
• Extended quit coordination. Added an immediate saving acknowledgement and a 60-second completion ceiling; awaited pastes, sends, and all screen saves before acknowledging completion.
• Recovered startup state. Retried an unsuccessful initial state read when the engine becomes ready.
• Preserved re-added pictures. Kept pictures removed and selected again during a pending send, and distinguished case-only filenames when copying attachments.
• Updated verification. Added targeted regressions, isolated the missing-uv test PATH, registered the new command permissions, and refreshed the formal source hash.

Validation: source tracing and regression-test inspection. Exact-head Linux CI has passed frontend, sidecar, and Rust tests; macOS has passed frontend and sidecar tests, with later checks still running. Formal verification passed. Local tests were not run because the required testing-doctrine fetch returned gh: Not Found (HTTP 404). The overlapping startup-read picture case is already explicitly tracked in #207.

✅ No new issues found.

Reviewed changes Reviewed 4798ac3, 176fde9, and cca2035 since the previous Pullfrog review at 05144bd.

• Retried failed quit saves. Retried persistence after engine readiness or a bounded delay, retaining the app and displaying an error if saving still fails.
• Cancelled unsuccessful quits. Added studio_flush_failed, its command permissions, and Rust handling that cancels held quit/close actions and permits a subsequent attempt.
• Required settled drafts before completion. Repeated the send/save barrier until no screen is sending or differs from its saved draft, including sends and edits begun during an earlier wait.
• Added regression coverage. Covered restart recovery, send/save overlap, persistent save failure, and a later quit after cancellation.

Validation: source tracing and regression-test inspection. Exact-head Linux CI has passed frontend, sidecar, and Rust tests; macOS has passed frontend and sidecar tests, with later checks still running. Formal verification passed. Local testing stopped because the required testing-doctrine fetch returned gh: Not Found (HTTP 404).

Explainer video for the merge decision, remade for the final head cca2035 (2:27). Also at https://artifacts.aojdevstudio.me/drop/20261108/3141f059-pr201-durable-switch-cca2035.mp4

It replaces the 5024e48 video. It adds two scenes, for drafts and sends and for quitting, and the closing proof is now the signed build of cca2035: a 20 mm cube sliced on the Mac mini, and the same build on the MacBook. The brief, the narration, and the stills come from this PR's body and diff. The second-model review (gpt-6.1-sol) came back CLEAN on round 1. ElevenLabs had no credits left, so the narration is the free macOS voice "Reed (English (US))", as before.

Spec fidelity and verify, head cca2035

Acceptance judge: GPT 6 Astra, the architect whose design won, re-judged the build against its plan and criteria A to L. Verdict: PASS WITH FOLLOW-UPS.

Deviations from the plan:

• E is partly met. Only the app's tools are registered, and ambient credentials are off. The run tool is not confined yet. Deferred to agent: confine the run tool's commands to the project folder #204.
• L ran the signed cube-to-3MF job on the Mac mini, not on m5. m5 has no UI-driver grant. The DMG sha256 (c065f140…4502e1) and the app and sidecar CDHashes match across the mini, the m5 smoke, and the MacBook install. Bambu Studio's "damaged" prompt on the mini's copy needed one manual Cancel. That hang is Slicing: the Bambu Studio version check has no time limit, so a held launch hangs the turn #210.
• Pi imports span more than one module. The plan said "one module". Astra judged this non-blocking.

Verify skill verify-materialize-3d on dev-substrate, detached checkout of cca2035, run 20261108-023633:

• PASS: the start screen shows.
• PASS: the engine line reads Engine 0.2.2.
• PASS: a start-screen draft survives a relaunch, with the exact text restored.
• PASS: the checkout is unchanged by the run.
• PASS: the sidecar's store sits in the app data folder (state/store.sqlite, owner.lock).
• Contrast sweep: 5 new controls are below 3.0. Ossie chose to merge and fix them first in the UI polish pass, tracked in Studio: five controls fail the 3.0 contrast check #211:
  • The prompt placeholder, 2.35.
  • The "API key or token" placeholder, 2.35.
  • The "Proxy URL" placeholder, 2.35.
  • Save, 2.94.
  • The disabled send, 1.28.
• The tool-list log check found no sidecar line in the log file it picked. That file was the second launch's short log. The tool list (read, write, edit, run, slice, astra) is proven in the m5 smoke of the signed DMG.

Follow-ups: #204, #207, #208, #209, #210, #211.

Merging on Ossie's explicit word. The blast radius is high.
