Prepare Factory Droid native transport with startup isolation hold - #2096
Factory native worker startup is held until inherited MCP server startup can be safely isolated. The adapter now reports unavailable and both normal launch and the direct host command refuse before helper/provider execution or runtime writes. Pre-existing managed workers are withheld from discovery, outbound caller/reply authority and incoming prompt delivery; their ownership records remain available for cleanup. Adding a private MCP alias and restricting tools does not exclude existing user/project/organization MCP startup, which can register or rotate an identity before a tool is requested.
The proposed native transport keeps a persistent JSON-RPC conversation, native session ID, serialized input, indexed delivery receipts, ambiguous-send fencing, and process-bound private Relay send capability. Those protocol/identity/delivery paths remain covered by tests, but production managed messaging is deliberately unavailable. Factory history collection is independent and remains RelayHistory's responsibility.
No global settings, HOME, model preference, credential, daemon, or existing session is changed. There is no bypass flag. A future isolated-profile design must verify all configuration sources and enroll its exact transcript root through RelayHistory before enabling startup.
Validation at b725a3304 (main 25974652f integrated; CHANGELOG was the only hand conflict):
27 focused Droid tests pass, including adapter/direct-host refusal before side effects and a positively verified pre-existing worker denied all communication without a control-socket connection; input pump, permissions, ambiguity, deduplication and identity regressions remain.
Formatting, public-source and diff checks pass. Rust-oleum 0.1.3: same 100 violations as exact main 25974652f, none added/regressed. Main already exceeds daemon/store ceilings; this PR does not raise or suppress them. Veto host-performed reviewer/security/secrets loop passes; not an independent review.
Exact-head production proof passes (including exactly one SafeError guidance line, no generic connection fallback): a disposable compiled sentinel is positively controlled, then the production host emits the specific isolation refusal without invoking the provider or opening its logs/readiness. The refusal test recovered into a locked worktree after unrelated external cleanup removed build objects. No actual Factory, MCP, model or auth startup occurs.
The prior f4a64ba9c full Relay Node CI (Linux/macOS/Windows) passed in run 42408209893. Current-head normal Actions are running in Relay Node CI 42416573409; earlier head 93fdfb1f9 had no normal pull_request workflows while its merge conflict was present, so a green broker-only rollup was not full CI. no broad local suite rerun during disk constraints.
The branch includes main 72d98585 through merge b921bebf9; the obsolete PR-proof jobs are removed. Normal CI remains the release gate.
Droid 1.6.0 native compatibility and an owned read-only turn were separately verified; Droid 0.148.1 rejected inference with the same valid key. This is not live Relay MCP or hosted-history E2E proof. Live managed startup and outbound MCP verification remain blocked pending a proven isolation contract.
Protocol and hold regressions: 27 focused Droid tests.
Exact production-entry negative proof using a disposable sentinel; no real Factory provider, MCP, key or model startup.
Formatting, public source, quality delta and host-performed Veto checks.
Full current-head GitHub Actions: running normally after main integration.
Live Factory messaging E2E: intentionally not run while startup isolation is unverified.
Screenshots: not applicable to this core transport change.
The follow-up component batch at 78daf7f68 adds an app-owned inert Factory MCP helper and a pure config migration planner. While startup is held, initialize/ping/list cause no enrollment or Relay IPC and effectful calls are denied locally. Migration requires a trusted app-saved source/name/value-digest record plus a recognized contract; it preserves unrelated and unproven entries and disabled state. Organization configuration and reload remain explicit blockers. No live config writer or startup enablement is added.
Validation of that batch: 40 focused Droid tests pass; the compiled real CLI passes the isolated normal/dev component test with unchanged config snapshots and no Unix socket connection; formatting and source checks pass. Independent adversarial/contextual review found no material defect. These checks establish component behavior only. Desktop ownership-record persistence, atomic config installation, effective organization/alias/reload proof, native enrollment and actual model/Relay/hosted-history E2E remain required.
CI repair at 39410bc07: the compiled droid_mcp integration target now explicitly requires production-binaries, matching the executable it invokes and the existing relay_core_binary target. Normal default builds still run every unchanged helper assertion; library-only builds intentionally have no production executable. The library-only full test-target compilation passes, and the real normal/dev compiled helper test passes. No production guard or test-body assertion is weakened. Fresh exact-head CI must complete before readiness is claimed.

This adds Factory Droid as a Relay-managed persistent native worker. Relay launches and tracks the worker, discovers verified sessions, and routes messages through a private control socket. The JSON-RPC engine serializes prompt turns, handles duplicate IDs, applies permission checks, and records uncertain submissions.
Droid is added to the session and partition types, harness registry, spawn settings, MCP selection, and hidden host and MCP commands. Droid target IDs must be UUID-shaped. Automatic final-answer reply settings cannot be enabled for Droid sessions.
The runtime verifies process and record ownership, serializes prompt delivery, and hosts the provider through JSON-RPC and a private Unix socket. The adapter launches, recovers, observes, and stops managed workers.
Session discovery and message routing crates/relay-node/src/relay/local.rs, crates/relay-node/src/relay/local/*, crates/relay-node/src/relay/local_methods/discovery.rs, crates/relay-node/src/relay/sessions.rs
Local Relay discovers verified Droid sessions and routes caller attribution, reply checks, and message injection through the Droid runtime. Droid receives a presentation partition and is excluded from automatic activation.
End-to-end proof and documentation tests/relayflows/cases/factory-droid-persistent-native-worker/*, crates/relay-node/README.md, CHANGELOG.md
The relay-flow case checks session startup, prompt delivery, duplicate handling, changed-payload refusal, and shutdown. The README and changelog describe the worker route and its constraints.

Explanation
The title names the Factory Droid native transport and the startup isolation hold, which matches the changeset's main thrust: the adapter reports unavailable and launch paths refuse before side effects. It is a little dense and mixes two ideas, but it stays on topic and is specific enough for a teammate scanning history.

Explanation
The description follows the repository template's sections in substance. It has a Summary-equivalent that explains the change, a Test Plan with checkboxes, and a RelayFlow Proof section. The Summary is not under a "## Summary" heading and the Screenshots section is absent, but its content is covered. The description is detailed about the scope: the native Droid worker is held and production managed messaging is unavailable, pre-existing workers are withheld, and the validation results are listed. It also states that live Factory messaging E2E was not run, and that full current-head CI is still running. The required template information is present. The description is long and dense, but it is not vague. It is mostly complete, so this check passes.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
Adding the known Swift enum case requires exhaustive SessionKind consumers to handle .droid; handling .unknown alone does not cover this new case.
The consuming application or its tests fail to compile until those switches are updated.
This can occur when: A Swift consumer compiled with the regenerated contract switches exhaustively over existing session kinds without a default branch.
Unverified finding

Provider::drop kills and reaps only the immediate Droid child, without terminating its tool or MCP descendants.
Tool subprocesses may remain orphaned after the worker is reported stopped.
This can occur when: A worker is stopped while a provider-launched subprocess is still running.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
stop requires the entire host/child pair to verify before stopping either process. If one process has died, this guard prevents cleanup of the surviving recorded process.
Release can leave the provider running without its controlling host.
This can occur when: The detached host is killed abruptly while Droid continues a long-running turn, then the worker is released.

executable names, such as droid-1.6.0, using the executable identity obtained
from ProcessTable. Preserve recognition of the existing names, validate
versioned names according to the established naming convention, and do not
broaden recognition in a way that crosses the unmanaged-child boundary.
Review comments at @crates/relay-node/src/relay/harness/droid.rs:
- Around line 124-127: Update the development check in the `development`
assignment to match the UTF-8-only behavior used by local plugins: only treat
the app-data directory name as ending in `.dev` when it can be read as UTF-8,
without lossy conversion.
- Around line 175-179: Update the Droid path discovery logic for
RELAY_DESKTOP_DROID and PATH entries to resolve each candidate to an absolute
path before returning it, so discovery completes before the worker’s working
directory changes. Preserve the existing usable check and candidate-selection
behavior.
- Around line 347-353: Update the Droid worker recovery flow around Target::new
and record.session_id to persist whether the initial task was handed off and
reconcile that state before retaining a recovered worker. If submission status
is ambiguous, determine its outcome without resubmitting the task; only report
handoff after confirming delivery.
- Around line 359-363: Update the stop method to remove the Droid runtime
records only after release is confirmed; retain the existing records when
release is not confirmed. Use the record and verified checks to identify the
released worker, and remove both associated records without changing the release
verification behavior.
Review comments at @crates/relay-node/src/relay/harness/droid/host.rs:
- Around line 170-171: Update CONTROL_LINE_LIMIT used by the host control-line
handling to accommodate the worst-case JSON-escaped 65,536-byte prompt, along
with the maximum ID and envelope overhead. Preserve the existing Engine::enqueue
text limit and ensure valid requests at that limit are not dropped before
enqueueing.
- Around line 281-285: Update the drive loop’s handling of rx.try_recv to
distinguish an empty channel from a disconnected one; when the provider-frame
reader exits, fail the host or mark the active turn uncertain and stop accepting
prompts until that state is handled.
- Around line 50-51: Ensure initialization and record-publication failures clean
up the socket bound by this host, while preserving the protection in the
UnixListener::bind path against unlinking a socket owned by an earlier host.
Establish ownership before removing the socket on these error paths; do not add
unconditional unlinking.
- Around line 308-309: Update the provider stdin write and flush in the
submission path so they cannot block control requests indefinitely; use a
bounded or otherwise nonblocking write strategy without weakening existing
safeguards. If a submission is interrupted before completion, mark it in doubt
rather than treating it as successful.
Review comments at @crates/relay-node/src/relay/harness/droid/protocol.rs:
- Around line 57-59: Update the turn admission logic in the enclosing protocol
handler so completed turns no longer permanently block new delivery IDs after
4,096 entries. Separate active-turn capacity from retained delivery-ID
deduplication, preserving duplicate protection for completed turns and refusing
new turns only when the worker’s active capacity is exhausted.
Review comments at @crates/relay-node/src/relay/harness/droid/registry.rs:
- Around line 78-83: Update the `verified` check to compare the running child’s
executable against the executable identity captured at launch, rather than
resolving the potentially retargeted `record.executable` symlink during
verification. Preserve the existing PID and ownership checks; retain launch-time
identity in the registry record without weakening those checks.
- Around line 160-162: Update the Droid delivery flow in deliver to distinguish
failures before any write from ambiguous or previously submitted attempts. Keep
definitely unsubmitted messages queued and retryable; preserve InDoubt handling
for ambiguous outcomes and attempts that may already have been submitted.
Review comments at @crates/relay-node/src/relay/local.rs:
- Around line 1168-1169: The SessionKind branch for Droid currently uses the
generic lock-held reply check, but Droid final-answer lookup is unsupported.
Implement final-answer extraction for Droid when reply_with_final_answer is
enabled, or reject that setting for Droid until extraction is supported; do not
leave it enabled while silently returning no answer.

Review fixes are pushed together in d57a9b439adde67c5d256bfc50d2dc9d439d6bc4.
The initial task is admitted before Ready is published, and recovery verifies the handoff ID. Completed delivery IDs move into an indexed private receipt journal, so the pending queue limit no longer becomes a lifetime turn limit.
Release independently checks the owned host and child, reaps an orphan child, and retires identity records only after both are gone. A changed installation symlink no longer changes the saved executable identity. Caller tests cover versioned executables and the nested unmanaged-worker boundary.
Provider output loss fails closed. Provider writes use a nonblocking pipe with a deadline, including the serialized production submission path. Control requests allow worst-case JSON escaping, socket cleanup covers initialization failures, and a bad individual client does not stop the worker.
Definitely unwritten control exchanges stay retryable; partial writes or lost acknowledgments remain uncertain. Retrying an acknowledged ID is still fenced by the host journal.
Relative executable paths and development-directory detection now match discovery. Droid rejects unsupported automatic final-answer forwarding; its replies use its private MCP. The production proof workflows run on Linux; a manual Windows case exits explicitly unsupported without producing a passing observation. Proof cleanup preserves the original assertion and attempts directory removal even if process-group cleanup fails.
Validation for this commit: 20 focused Droid tests pass, as does the exact committed production-host disposable-peer case. Rust formatting, Prettier and the public-source check pass. Rust quality has the same 99 existing violations as base, with no new/regressed violation; extracting reply-setting policy lowered the existing file-length ceiling. The real Veto tool's host-performed code/security/secrets audit passed (not an independent review).
The broad suite passed 2,557 tests at the original feature head. Its review-batch rerun was interrupted by shared disk exhaustion and is not claimed green; fresh-head CI is running. The synthetic peer proof also does not claim a live Relay MCP exchange or hosted history readback.

Remove journals when workers are released
Each launch creates a separate receipt database. Release removes the discovery records but leaves the database, and startup failures after its creation can also leave it behind. Repeated launches can accumulate disk usage without a bound. Reclaim the journal after the host has stopped, including failed startup, while preserving it for live hosts.

feat: add persistent Factory Droid workers with scoped Relay messaging
Prepare Factory Droid native transport with startup isolation hold
Nov 7, 2026
Forward-merged main 1db553041 as 7272f1c38. Only CHANGELOG.md required a manual resolution; it keeps the Factory unavailable notice pending and preserves main’s published release notes. The Factory host, MCP helper, migration planner and focused test bytes are unchanged from 39410bc07. Fresh cargo check --manifest-path crates/relay-node/Cargo.toml --all-targets --all-features passes. Scoped conflict-resolution review passes.
This preserves the managed startup hold. A task-private static inspection of official Factory CLI 1.6.1 still finds the same configured-plus-client MCP merge as 1.6.0; no exclusive pre-start source boundary has been established. No real Factory launch, model, MCP send, credential access or E2E proof was performed for this source integration.
Forward-merged current main at f86ebb6 in a8a203d. Root package manifests now match the canonical #2134 lock exactly; #2135 is superseded.
Adapted Droid private host/helper to main’s shared Build/profile API and preserved Production selection for invalid UTF-8 directory names. Native startup isolation remains held before runtime/provider effects; this does not enable Factory spawning.
Validation: cargo check --all-targets --all-features passed; 40 Droid tests and the CLI leading-hyphen profile test passed. Scoped Veto review passed (host-reasoned; no independent sampling/runtime proof claimed).

Factory native worker startup is held until inherited MCP server startup can be safely isolated. The adapter now reports unavailable and both normal launch and the direct host command refuse before helper/provider execution or runtime writes. Pre-existing managed workers are withheld from discovery, outbound caller/reply authority and incoming prompt delivery; their ownership records remain available for cleanup. Adding a private MCP alias and restricting tools does not exclude existing user/project/organization MCP startup, which can register or rotate an identity before a tool is requested.
The proposed native transport keeps a persistent JSON-RPC conversation, native session ID, serialized input, indexed delivery receipts, ambiguous-send fencing, and process-bound private Relay send capability. Those protocol/identity/delivery paths remain covered by tests, but production managed messaging is deliberately unavailable. Factory history collection is independent and remains RelayHistory's responsibility.
No global settings, HOME, model preference, credential, daemon, or existing session is changed. There is no bypass flag. A future isolated-profile design must verify all configuration sources and enroll its exact transcript root through RelayHistory before enabling startup.

Normal CI remains the release gate.Droid 1.6.0 native compatibility and an owned read-only turn were separately verified; Droid 0.148.1 rejected inference with the same valid key. This is not live Relay MCP or hosted-history E2E proof. Live managed startup and outbound MCP verification remain blocked pending a proven isolation contract.

The follow-up component batch at
78daf7f68adds an app-owned inert Factory MCP helper and a pure config migration planner. While startup is held, initialize/ping/list cause no enrollment or Relay IPC and effectful calls are denied locally. Migration requires a trusted app-saved source/name/value-digest record plus a recognized contract; it preserves unrelated and unproven entries and disabled state. Organization configuration and reload remain explicit blockers. No live config writer or startup enablement is added.Validation of that batch: 40 focused Droid tests pass; the compiled real CLI passes the isolated normal/dev component test with unchanged config snapshots and no Unix socket connection; formatting and source checks pass. Independent adversarial/contextual review found no material defect. These checks establish component behavior only. Desktop ownership-record persistence, atomic config installation, effective organization/alias/reload proof, native enrollment and actual model/Relay/hosted-history E2E remain required.
CI repair at
39410bc07: the compileddroid_mcpintegration target now explicitly requiresproduction-binaries, matching the executable it invokes and the existingrelay_core_binarytarget. Normal default builds still run every unchanged helper assertion; library-only builds intentionally have no production executable. The library-only full test-target compilation passes, and the real normal/dev compiled helper test passes. No production guard or test-body assertion is weakened. Fresh exact-head CI must complete before readiness is claimed.
