Replace the earlier peer-authentication proposal with the reviewed,
implementation-oriented design. The plan now records the identity-storage
state machine, pinned TLS and endpoint rules, signed Call-to-Play objects,
download-source authorization, resource limits, safe protocol phases, and
phase-owned acceptance gates.
Remove the standalone review after incorporating its findings and follow-up
adjudication into the authoritative plan, including an explicit closure matrix.
This avoids maintaining two documents with conflicting severity and guidance.
Test Plan:
- `git diff --cached --check` -- passed
- Code tests not run; documentation-only change
Treat an unavailable actor ID or an explicit not-ready result as normal peer
startup and tell the user that LAN connection is still in progress. Clear that
message when snapshot registration succeeds.
Map obsolete, missing-history, and active-history-limit store failures to
distinct guidance without marking a healthy transport unavailable. Preserve a
generic message for unexpected publish failures.
Test Plan:
- just frontend-test
- just build
- git diff --cached --check
Pass the effective nomination deadline into the Add time action and extend
from whichever is later: that deadline or the current time. This preserves
remaining time when a call becomes ready early while still giving an overdue
call a fresh five-minute window.
Test Plan:
- just fmt
- just frontend-test
- just build
- git diff --cached --check
Keep complete running and cancelled histories visible for fifteen minutes so
peers retain the roster, chat, and outcome long enough to understand what
happened. Compact them to terminal tombstones afterward without charging
settled calls against the active-history limit.
Model running and cancelled as durable read-only frontend states, exclude
them from active badges, prune retired raw events, and document the lifecycle.
Add peer scenario S49 to prove a late joiner reconstructs a terminal call with
its roster and chat intact.

Raise the wire protocol to version 7 and add explicit Call to Play delivery
outcomes. Live requests now wait for an application acknowledgement, allowing
the sender to distinguish applied, duplicate, obsolete, incomplete, and
rejected updates instead of treating a successful write as acceptance.
Remove source-IP equality from actor verification. The receiver now requires
the envelope peer ID to be present in its known roster and requires every live
event actor to match that envelope. This matches the cooperative-LAN trust
model without misrepresenting the shared TLS identity as per-peer
authentication.
Transport failures, malformed responses, NeedHandshake, and NeedHistory each
trigger one asynchronous Hello/HelloAck resync. Rejections are logged without
retry, and local publication remains independent of remote availability.
Test Plan:
- `just fmt` -- passed
- `just clippy` -- passed

Replace per-event insertion with a transactional batch merge. The store now
validates and deduplicates an entire history before committing it, rejects
conflicting event IDs without partial mutation, evaluates retention after all
batch events are present, and reports applied, duplicate, obsolete, and
missing-root outcomes explicitly.
Derive event identity from retained history instead of preserving an unbounded
ID set. Expired histories can therefore be restored by a complete Create plus
AddTime batch, while orphan actions request history and terminal tombstones
continue to reject stale resurrection. Capacity applies only to unresolved
history, allowing Start and Cancel to settle a full call.
Only retained events reach the UI or live broadcast path. Handshake and live
merge callers log invalid or incomplete histories without publishing events
that compaction discarded.

- `just fmt` -- passed
- `just clippy` -- passed
- `just test` -- passed
- `git diff --cached --check` -- passed
Expired call histories were removed on the next store insertion, so an otherwise
idle peer could continue carrying stale payload through handshakes after the
five-minute UI retention ended.
Run the same inactive-call compaction before local and handshake snapshots. This
makes the expiry boundary exact without trimming any event from an active call.

A failed fire-and-forget event left one peer's active call state divergent until
some later discovery or reconnect happened. During a LAN party that could leave
different players looking at different rosters or chat.
Fall back to the existing bidirectional handshake whenever a live Call to Play
send fails. Its active-history exchange heals both sides immediately when the
failure was transient. Document the related wall-clock synchronization
assumption for deadline and countdown presentation.

Deadline completion previously shared the green Ready presentation with a full
roster and remained visible forever. An abandoned call therefore looked ready
to launch and required its creator to return and cancel it.
Give elapsed calls a distinct Time's up state and a five-minute grace period in
which the creator can start or extend them. After that, both the reducer and
peer store remove the call as a unit. Filled calls remain ready until their
deadline, and active calls continue to retain complete history for late joiners.

Calls for a game missing from the local catalog still contributed to the badge
but were discarded by both the ticker and overlay. Opening the badge could
therefore show a blank modal with no explanation.
Render those calls with an unavailable-game label, the sender and game ID, the
normal roster and chat, and safe coordination actions. The creator can mark the
match started, but automatic launch remains disabled until catalog data exists.

The 4,096-event store retained every completed call forever and local commands
only reported that they reached the queue. Once the bound was reached, GUI
actions could therefore fail with no user-visible result. The CLI snapshot wait
could also be satisfied by an unrelated live event.
Keep the complete event and chat history for every active call so late joiners
receive full context. When the creator starts or cancels a call, replace its
history with a single terminal tombstone; this bounds retained payload while
still healing peers that missed the live terminal action. Publish commands now
reply with the actual store result, and CLI snapshots use a direct reply.

Participant maps and creator authorization previously used display names, so
two peers left at the default Commander name collapsed into one participant
and could exercise each other's creator controls through the normal client.
Carry a stable actor_id separately from actor_name. The peer overwrites actor_id
on every local publish, and live event envelopes are accepted only when the
known peer, source, and event actor match. The frontend keys participants and
authorization by actor_id while retaining actor_name for display. This follows
the trusted-LAN model and is not cryptographic authentication against a hostile
peer.

Implement the launcher design as a production peer-to-peer feature. Call to
Play actions are immutable, validated events broadcast over the existing QUIC
control channel, deduplicated in a bounded in-memory history, and exchanged in
Hello/HelloAck so late joiners reconstruct current calls.
Add the Tauri bridge and modular launcher surfaces for play-now and scheduled
calls, check-in, readiness buffers, role-aware controls, chat, tickers, and
actual caller launch. A deterministic frontend reducer derives presentation
state from replicated history. Extend the JSONL peer harness with publish/list
commands and a three-peer live-delivery and late-join scenario.
This intentionally raises the only supported wire protocol from version 5 to
version 6; older builds are not supported. Document the transport architecture
and exclude generated peer-test state from Docker build contexts.

Extend the launcher design specification and prototype reference with the
"Call to Play" multiplayer coordination feature and clean up top-bar chrome.
Key additions and changes:
- Spec & Roadmap: Document Call to Play mechanics in SPEC.md, including Play
Now / Scheduled call flavors, 15-minute check-in windows, top-bar button
with active count badge, quick-bar ticker stack above grid, overlay modal,
and per-call group chat. Update design/README.md.
- Components & Logic: Add calltoplay.jsx and ctp-chat.jsx components for call
creation, status progression, and chat. Extend data.jsx with a mock peer
roster (PEERS) and helper functions for peer install count tracking.
- Top-bar Cleanup: Move game-folder configuration from top bar into Settings ->
Library, freeing top-bar space for the Call to Play action button.
- Styling & Layout: Add CTP quick-bar, ticker, badge, card, and chat styles to
styles.css, and integrate CTP components into launcher.jsx, components.jsx,
and SoftLAN Launcher.html.
Test Plan:
- `git diff --cached --check` -- passed (no trailing whitespace or conflict markers)
- `cargo check --workspace` -- passed cleanly
- Manual review of staged diff across 9 design/launcher files -- confirmed clean staging
Bug report: unrar.exe kept running after closing the launcher during a
game install. The orphaned process kept extracting in the background and
held file handles on the staging directory.
Root cause (regular install path): run_unrar_sidecar ran the unrar
sidecar via tauri-plugin-shell's Command::output(). That helper spawns
the process on a detached SharedChild OS thread and immediately drops the
CommandChild; there is no Drop impl that kills the process. On app exit
only shutdown_peer_runtime ran, and Windows does not cascade-kill child
processes, so closing the launcher left unrar running.
Fix:
- run_unrar_sidecar now uses .spawn() instead of .output(), keeping a
killable CommandChild. It registers the child in a new
LanSpreadState.active_unrar_children registry and an RAII
UnrarChildGuard deregisters it on every return path. The CommandEvent
stream is drained to reproduce the exact stdout/stderr (NEWLINE_BYTE
is b'\n'), status code, success flag, and UnpackLogEntry the old
.output() produced, so logging behavior is unchanged.
- kill_active_unrar_children() runs in the RunEvent::Exit handler before
shutdown_peer_runtime, killing every in-progress unrar. Killing first
also lets the install task unwind so the runtime stops promptly.
Two concurrency hazards were closed in the registry design:
- Children are keyed by a monotonic id, not pid. A pid key let a
finishing install's guard deregister a different install's child after
the OS recycled the pid, which could re-orphan a live child.
- A shutting_down latch lives in the registry under the same mutex as
the kill sweep. The sweep is a one-shot drain, so a child registered
after it (a task caught between spawn() and registration, or a later
archive in a multi-archive install -- unpack_archives does not observe
the shutdown token) would be missed. Registration now checks the latch
under that mutex and kills the child immediately instead of inserting
it. Since registration and the sweep serialize on one mutex, every
interleaving kills the child.
Also hardened the streamed-install sender path (ExternalUnrarStream
Provider) with kill_on_drop(true) on its tokio unrar spawns, so a
dropped or aborted producer task cannot orphan unrar there either.
Known limitation: a hard force-kill or crash of the launcher (e.g. Task
Manager -> End Task) bypasses RunEvent::Exit and is not covered. Making
that bulletproof would require a Windows Job Object with
JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE; the reported "close the launcher"
case is fully fixed.
Test Plan:
- just clippy (pedantic, -D warnings): clean.
- just fmt: no changes.
- just test: all suites pass (incl. the 20 Tauri-lib unit tests).
- Manual (Windows): start a game install, close the launcher mid-extract,
confirm no unrar.exe remains in Task Manager. Repeat with two
concurrent installs and with a multi-archive game.
An adversarial audit of the headless peer-to-peer scenario suite
(crates/lanspread-peer-cli/scripts/run_extended_scenarios.py, driven by
`just peer-cli-tests`) found assertions that passed even when the behavior
they claim to test was not happening, plus timing races and doc-vs-code
divergences. A full baseline run (S1-S47) passed beforehand, confirming these
were test-quality gaps, not peer regressions; the baseline output itself
exposed the worst offenders -- e.g. S14 chunk totals {128 MiB, 1 MiB} (a
two-chunk file whose "balanced within one chunk" check can never fail) and
S16/S18 serving the whole ~120 MiB alienswarm.eti from a single source, so
fanout and retry were never exercised.
Test-correctness fixes (a broken behavior could previously pass green):
- S18: the "no download-failed" check was dead -- it reused a LineWaiter
already advanced past download-finished, so it scanned an empty tail.
Replaced with assert_no_event_since over the whole window. Switched to a
4*CHUNK_SIZE sparse archive so both peers get chunks; the test now proves the
download SURVIVES a mid-download source kill (every byte delivered, survivor
served part, no download-failed, clean diff). Retry-onto-survivor is the
mechanism but is not asserted: the kill/serve race against `docker rm -f`
cannot be forced, so asserting an exact split would be flaky.
- S7: the only check was a diff against byte-identical ggoo fixtures, so it was
source-agnostic. Added assertions that the download committed exactly once,
every chunk came from the validated two-peer set, both peers served, and no
chunk was fetched twice.
- S14: enlarged to 4*CHUNK_SIZE so the balance check can fail under a 3+1
imbalance; asserts an exact 2+2 split summing to the file size.
- S16: inflated the .eti to 2*CHUNK_SIZE so it fans out across both
catalog-version peers (the stock 120 MiB fixture is a single chunk).
- S37: validate the throughput rate fields (positive, self-consistent
mbit/mib == 8.388608, mib_per_s == bytes/duration), not just the byte count.
- S35: assert the source actually advertises the unknown game before checking
it is filtered, so "absent" means "filtered" and not "never sent".
- S15: cross-check each peer's raw advertised eti_version via list-peers; the
list-games eti_game_version is synthesized from the catalog and can only ever
equal the asserted value.
- S2: poll for library convergence and verify the bidirectional exchange
(bravo sees alpha's 3 games, not just alpha seeing bravo's 4).
- S12/S28: require the gating unit test to appear as "<name> ... ok" so an
#[ignore]d (un-run) test no longer satisfies the check.
- S24/S25: assert the requested install=false final state.
- S34: assert exactly 21 coherent chunks (20 files + version.ini), 21 distinct
paths, no duplicates, instead of a >= 21 floor.
Flake fixes:
- S19: force-kill the sole source right after download-begin on a 4*CHUNK_SIZE
file and accept download-failed or download-peers-gone. The old graceful
shutdown on a single-chunk file could let the transfer finish first, turning
the expected failure into a download-finished. A chunk may complete before
the kill lands, but the full transfer cannot, so the failure is deterministic.
- S26: use a large sparse source so the first operation is reliably still
active when the duplicate request is issued (TOCTOU on active_operations);
also assert the active operation == "Downloading".
- S11: drop the "listener address must change" assertion -- it tested the OS
ephemeral-port allocator and could fail spuriously; keep the same-identity /
no-duplicate invariant.
Coverage and determinism:
- S27: add handshake::tests::inbound_hello_from_self_is_ignored for the
protocol-level self guard. The CLI scenario only exercises the CLI
string-compare guard, which short-circuits before any network call, so the
peer-crate guard had no test.
- find_fixture_game now iterates sorted(FIXTURES) so the ambiguous cnctw
(fixture-bravo/multi/solid) resolves deterministically to fixture-bravo.
Reviewed and deliberately left as-is (documented in the run log): S20, S21,

passed; post-fix passed; a final run on the exact committed code passed
47/47. Evidence: S14 {268435456, 268435456} balanced 2+2; S16 .eti split
across B and C {134217728, 134217728}; S18 all 536870912 bytes delivered with
no download-failed; S19 deterministic download-failed; S37 ~874 MiB/s.
- `just test` (incl. inbound_hello_from_self_is_ignored), `just clippy`

Add a peer-cli-tests just recipe as the public entry point for the existing
extended scenario runner. The recipe depends on peer-cli-image, so Docker
uses its normal layer cache to decide whether the image needs rebuilding
before the Python harness runs.
This gives contributors one memorable command for the full S1-S47 matrix
while still allowing selected scenarios as positional arguments. The
underlying runner continues to own container topology and JSONL command/event
handling.

An emit-vs-listen audit of the event surface showed the GUI is
state-as-source-of-truth: useGames renders the complete `games-list`
snapshot (full library + active_operations) and reconstructs status from
it, not from a stream of granular events. Several PeerEvents were emitted
but had no consumer at all -- no frontend `listen()` and no peer-cli
scenario assertion -- so they were pure dead weight that made the backend
look event-driven when it no longer is.
This prunes that dead surface in two parts.
1. Remove three PeerEvent variants with no consumer: InstallGameBegin,
UninstallGameBegin, and RemoveDownloadedGameBegin. The operation-start
transition is still observable via ActiveOperationsChanged (the
snapshot already carries the Installing/Updating/Uninstalling/
RemovingDownload kind), so nothing is lost. This drops their emit
sites in handlers.rs, the begin-event assertions in the peer's
lifecycle unit tests (the asserted sequence is now
ActiveOperationsChanged(kind) -> LocalLibraryChanged ->
ActiveOperationsChanged([]) -> *Finished), the peer-cli JSONL
mappings (install-begin/uninstall-begin/remove-download-begin) plus
the now-orphaned install_operation_name helper and InstallOperation
import, and the matching Tauri handler arms.
2. Drop Tauri webview emits that no frontend listener consumed:
peer-local-ready, game-download-begin, game-download-pre,
game-download-finished, game-uninstall-finished, and
peer-connected/-disconnected/-discovered/-lost. The log lines and all
real side effects are kept (handle_got_game_files still forwards
PeerCommand::DownloadGameFiles). The orphaned emit_peer_addr_event and
handle_download_finished helpers and the now-unused SocketAddr import
are removed. peer-runtime-failed is kept pending a decision on
surfacing runtime failures in the GUI.
Why not re-wire instead: under state-as-source-of-truth, per-event UI
state is exactly the pattern this project abandoned. Live progress
already flows via game-download-progress, and the peer-cli's chunk,
timing-trigger, and transition assertions read events that are retained
(download-begin, download-chunk-finished, the *-finished/*-failed
terminals), so test coverage is unchanged.
Behavior change: none functional. The Tauri backend no longer emits
events nothing listened to; the GUI is unchanged. The peer-cli no longer
emits the three *-begin JSONL events. PeerEvent is a workspace-internal
UI-reporting type, not a wire-protocol type, so there is no protocol or
version impact and all consumers are updated in this commit.
Docs: PEER_CLI_SCENARIOS.md S39 no longer lists install-begin (with a
note that the start transition is visible via active-operations-changed),
and a dated Run Log entry records the removal. The historical 2026-05-18
run-log note is left intact as a dated observation.
Test Plan:
- just test: pass (incl. peer lifecycle event-sequence tests).
- just clippy: pass (-D warnings, all targets).
- just frontend-test: pass (11/11, incl. streamed-install gating/labels).
- just build: pass (release, no bundle).
- Not run: the Docker S39-S47 matrix (run_extended_scenarios.py); those
scenarios never asserted the removed *-begin events, so coverage is
unaffected. just fmt's tombi step needs network and was skipped; no
TOML changed.
Refs: peer event-surface emit-vs-listen audit; no external consumers of
the removed events.
`just clippy` was failing on peer test and helper code after the current lint
set denied warnings. This keeps the cleanup local to the reported warnings and
avoids changing runtime peer behavior or the wire protocol surface.
The test helpers now avoid needless ownership, active-operation assertions take
slices, and the local monitor watch-event helper no longer wraps a value that
cannot fail. The install recovery matrix keeps the same cases, but moves the
case table and per-case assertions into helpers so the test body stays below the
clippy line limit. The remaining lint fixes replace similar temporary names and
use an explicit `expect` message for test-only length conversion.
No separate project documentation update is needed because this only changes
internal test/helper structure and lint-only assertions; the existing peer
architecture docs remain accurate.

A streamed install sender kept the original frame sink alive outside the
producer task. After the producer sent Complete, or an Error for a provider
failure, the forwarding loop still had a live mpsc sender in scope and waited
forever for another frame.
Move the sink into the producer so the channel closes when the producer exits.
That lets the QUIC writer close, the request task return, and the outbound
TransferGuard drop after successful streamed installs and provider-side
failures.
The peer-cli harness now keeps the outbound-transfer map it passes into the
peer runtime and exposes per-game counts in status. S39 asserts that the source
has no active outbound transfer for cnctw after the streamed install finishes,
which catches the sender-side lifecycle leak that receiver-only assertions
missed. The peer-cli README and scenario table document that status field and
expectation.

Refs: NEXT_STEPS.md streamed install lifecycle hardening
Claude Fable 5's branch review found that receiver cancellation or a QUIC
send failure could leave the sender-side archive producer blocked on the
bounded frame channel. That kept the outbound transfer guard alive and could
block later installs or updates of the same game.
Route archive frames through a cancellable StreamInstallFrameSink instead of
exposing the raw channel sender to providers. The QUIC forwarder now cancels
and closes the receive side before awaiting the producer, so a blocked send
wakes and the transfer guard can drop normally.
Make PeerCommand::StreamInstallGame own its peer metadata preflight inside the
peer core. The Tauri layer now sends the command directly, and the peer runtime
fetches file details from catalog-version peers before running the existing
majority validation and retry logic. This removes the UI-only pending streamed
install set and gives PeerEvent::GotGameFiles one meaning again: continue a
normal archive download.
Tighten the receiver transaction edge cases too. Rollback removes a newly
created empty game root, but preserves pre-existing roots. Once streamed
staging has been promoted to local/, intent or launch-settings cleanup failures
are logged for startup recovery instead of reporting a failed install for bytes
that are already committed.
Accept missing RAR CRC32 metadata for zero-byte files as CRC32 00000000 while
still requiring CRC32 metadata for non-empty files. Update the peer README,
scenario docs, and next-steps handoff so the documented ownership and remaining
trust limitation match the implementation.

Remote aggregation now filters to catalog-version roots, but the checked-in
peer-cli fixtures and skew scenarios still stamped synthetic future versions.
That hid fixture rows in S3 and left scenario docs asserting latest-version
behavior.
Teach the harness the catalog versions for fixture game IDs, stamp generated
fixtures with catalog versions by default, and update skew, mesh, propagation,
and throughput scenarios to expect only catalog-version peers. Also wire S38
into the executable matrix so the documented first-play launch-setting scenario
is covered by the same full run as S1-S47.
This keeps stale peers as negative coverage: they are absent from list-games and
cannot provide descriptors, votes, or chunks. The fixture version.ini updates
are checked in so alpha, bravo, charlie, and persona roots advertise
downloadable catalog games again.

NEXT_STEPS item 7 needed the installed-but-not-downloaded state to be
clear to users. Keep streamed installs in the installed visual state so
sorting, filters, and the primary Play action stay unchanged, but make the
sharing limitation visible in the UI.

status says `Installed, not shareable`. Downloaded-and-installed games
keep the normal `Installed` wording.

NEXT_STEPS item 6 called for the remaining streamed-install edge cases to
be covered in the peer-cli matrix. Add S43-S47 for already-installed
rejection, corrupt archive rollback, sender disconnect, receiver cancel,
and sorted multi-archive streaming.
The receiver-cancel scenario needs the harness to drive the same runtime
path as the GUI, so `lanspread-peer-cli` now accepts a narrow
`cancel-download` command that forwards to `PeerCommand::CancelDownload`.
A parser test covers the new JSONL command shape.
Add `fixture-multi/cnctw`, a tiny two-archive RAR fixture. S47 uses it to
prove streamed installs process root `.eti` archives in sorted order and
commit only extracted `local/` payloads, not the root archives or
`version.ini` sentinel.
