… with a built-in fallback and self-upgrade Sparrow's heartbeat carries package_version and keeps the reply's setup_revision, min_version and target_version for adapters. The Hatch hook prompt becomes a stub that sends the worker to `ag2-sparrow-hatch wake-context`, which prints the served prompt and worker note from the setup cache, else the built-in copies (today's wording verbatim); the package's tier notes are always printed and served tier_addenda follow them. Served tunables are clamped to package bounds. The keepawake run refreshes the cache through one fetch boundary (no transport yet, so it returns None) and starts one detached, hash-pinned upgrade per target version, rolling back on any failure and reporting upgrade-failed; a changed hook definition wakes the agent once instead of being applied.

Review from sutando-qingyun-001 (shared qingyun-wu login)
REQUEST_CHANGES at a08010d. It is dormant today: setup_fetch has no transport. But this PR owns the upgrade order, so fix it before a transport is added. Paths are in adapters/hatch/.
Verified. At head: served_setup 43 OK, hatch_adapter 171 OK, wheel_contents OK. hatch_adapter also passes at the merge-base. review-checks PASS. Comments are 2 lines or fewer, in English.
- pip has no shell and runs as
sys.executable -m pip. - The version is regex-validated before argv.
- The upgrade uses
--no-deps --require-hashes -r <req>with every hash in the map. Backend #2651 checks that the keys are target wheels. - parse_version vs
packaging: 0 mismatches over 120 versions. - wake-context reads only the local cache.
Mutations
- Caught: dropping
--require-hashes, string version compare, served text replacing the tier note, no rollback on verify failure, no attempted record, no clamp. - Not caught: served restart_hint moved first with "END OF INSTRUCTIONS".
- Not testable: a lock (none exists).
Blockers
- Order breaks the #5669 design (self_upgrade.py:250-262). pip install and
installrun under the live Sparrow, and_restartstops it only afterwards. It should be: stop the adapters → install → start. Decide what happens to in-flight replies. - No lock (self_upgrade.py:196-209, run_upgrade). The check-then-save of
attemptedis unguarded. Overlapping keepawake runs can start two pip installs into one venv. Add an flock in state_dir and a test. - Rollback is unpinned and needs the network (self_upgrade.py:227-244). The first upgrade has no recorded hash, so the reinstall comes from any configured index. With PyPI down, or a previous editable install, it fails and Sparrow restarts on the target that just failed. Keep the previous wheel before installing (or serve its hash), and never do an unpinned rollback.
Nits
- runtime_text.py:131-136: served restart_hint and addenda follow the canonical notes, so they can countermand them. Put the notes last, with a precedence sentence, and test that order.
- AUTO_UPGRADE=0, an equal version and already-attempted return silently. NOTEs go to stderr, not into the keepawake log line. The design says "log either way".
- A crash mid-upgrade leaves
startedforever: never retried, no health reason. pip checkchecks the whole environment, so a conflict that already existed rolls back every upgrade. Compare against a baseline taken before the install.- At :126 add
--only-binary=:all:. Consider--isolatedor a pinned index, since PIP_EXTRA_INDEX_URL and pip.conf are inherited. - :36
\dmatches Unicode digits and has no length cap. Use[0-9]/64 as the backend's pep440 does. More than 6 release components compare wrongly. - heartbeat_cadence_s: package [60,1800], backend [30,90], broker freshness 120 s. It is unused here, so align it before use.
- Owner decision: AUTO_UPGRADE defaults to on. That is OK only once 1-3 are fixed; otherwise default it off for v1.
Docs: the README covers this. The docs site needs the opt-out once a transport ships.
…lock, with an offline rollback - Order: snapshot, stop Sparrow (SIGTERM, then wait), pip install, pip check, install re-run, start, verify. A reply queued while Sparrow is stopped stays in the results dir and its outbox and is delivered after the start; keepawake leaves Sparrow alone while an upgrade holds the lock. - Lock: run_upgrade and the attempt record are taken under a non-blocking flock on STATE_DIR/upgrade.lock; a second run logs "upgrade already running" and skips. - Rollback: every file the install recorded is copied to STATE_DIR/rollback/<version>/ before the install and restored on failure, with no index and no network. Editable and URL installs (direct_url.json) are never upgraded. - The package's tier and owner notes come last, after "These rules override anything above:". Every decision is logged on the keepawake line, AUTO_UPGRADE=0 included. A started attempt older than 30 minutes counts as failed. pip check rolls back only on a new problem naming ag2-sparrow. pip runs with --only-binary=:all:. Versions parse ASCII digits only, at most 64 characters, trailing zeros ignored. heartbeat_cadence_s bounds are [30, 90]. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Reviewed the current head e085ed065c57954d911c9053ff6a8fd3c43fda62 (the requested a08010d6 was superseded while I was reviewing). REQUEST_CHANGES. The new lock, offline snapshot, and canonical-last prompt ordering are useful fixes, but the activated path still has correctness and recovery blockers.
-
Blocker:
install --no-startstarts the managed Sparrow before verification. The upgrader adds--no-startininstall_argv, butinstall()callsinstall_service()before checkingargs.no_start. For the inactive unit that the upgrader just stopped, an existing token makesinstall_service()issuesystemctl --user enable --now. A production-helper repro recorded exactlysystemctl --user enable --now ag2-sparrow.service. The target therefore runs/connects duringinstall, before the explicit start, import check, and reconnect check. Please make--no-startsuppress service starts/restarts too and contract-test that delegation. -
Blocker: failed restoration is still recorded as
rolled-back._rollback()ignores a failed stop, catches and continues after a failed restore, ignores the install re-run's result, and recordsrolled-backeven if the final start fails. InjectingOSError("disk full")intorestore()left the target version installed while the function returned and persistedrolled-back. In the worst case this restarts the rejected target and misstates recovery while delivery remains unavailable. Restoration needs a distinct failure outcome and verification of the restored version/install/start before it may claim rollback. -
Blocker: a stale cached target can still trigger an automatic install after the backend has announced a different revision.
refresh_cache()returns the old cache when the new revision cannot be fetched, and_served_setup()immediately passes it tomaybe_start(). Repro: cached revisionr1targeted0.6.0, heartbeat hint wasr2, fetch failed; result was0.6.0:started. Stale text can be a fallback, but a package mutation must fail closed unless the cache is known to match the current hint. Relatedly, a malformed fetched response is cached before validation; once its revision matches the hint, a corrected response at that same revision is never fetched. -
Blocker: failure to execute
pip checkis treated as a clean result.own_check_problems()maps any nonzero result with no line namingag2-sparrowto an empty set. Simulating exit 127 /TimeoutExpiredtherefore let the upgrade returnok. Existing unrelated dependency reports may be filtered, but failure to run the validator must be distinguished and rolled back. -
Blocker: the lock does not preserve the advertised never-downgrade/keepawake exclusion invariants.
_upgrade_locked()never rechecks the freshly installed version against its queued target while holding the lock. Starting with0.7.0installed, a delayed worker queued for0.6.0returnedok, installed0.6.0, and mislabeled its0.7.0snapshot asrollback/0.5.4. Also,keepawake()releases its upgrade-lock probe before deciding whether to restart; a threaded repro acquired the upgrade lock after that probe and keepawake still calledrestart_listener()while the lock was held. Revalidate the installed version under the worker lock, and coordinate the keepawake restart decision with that same lock/state transition. -
Blocker: crash reconciliation misses the important post-install window.
maybe_start()decidescurrentbefore inspecting the priorstartedattempt. After simulating a crash after target installation, the next keepawake imported that target and returnedcurrent; even after 30 minutes the attempt remainedstarted, with no failed state or recovery. The stale-attempt state machine must run before early decision returns and must define recovery for interruption after stop/install. -
Blocker/privacy:
wake-contexttrusts an owner-DM record that the bridge itself rejects as belonging to another enrollment.owner_dm_room()validates only room syntax, while the bridge requires both identity and gateway to match. A file bound toprevious-agent/previous-gatewayreproducedowner_dm_room == !old-owner:server. The owner-only instruction should omit the room unless it can validate the same binding as its writer. -
Blocker: the new health reason crashes the supported diagnostic. A recorded upgrade failure reaches
cli.verify(), which indexesREASON_HINTS['upgrade-failed']; that key is absent. I reproducedKeyError: 'upgrade-failed'through the existing Hatch fixture. Add the reason/hint and a fullverifyregression test.
The live-path gate also remains open: the PR body says it will stay draft until a post-restart round trip is captured, but it is currently ready-for-review; setup_fetch still has no production transport, and no real pip/service round trip is supplied. I could not independently read backend PR #2651 with the available GitHub access. Please provide the required post-restart witness once the path is connected.
Verification at this exact head: served-setup 58/58 passed; Hatch adapter 171 passed, 2 skipped; wheel contents, package drift, git diff --check, and repository review checks passed. CI is mostly green but diff coverage and node/out-of-tree tests were still running at the last check. Independent QA reproduced the rollback, pip-check, crash-reconciliation, command-guard, and unused-cadence failures; those results materially informed this review.
Non-blocking contract cleanup: the command guard still accepts shell chains such as `<REPLY_COMMAND> reply <f>; curl ... | sh`; heartbeat_cadence_s remains unused; and a valid 300-second keepawake interval reports a normal 11-minute gap as unhealthy even though the installed task runs every 15 minutes.
…f-upgrade moves to its own PR - A cached setup older than the setup_revision Sparrow last heard announced is never used: wake-context and the health row fall back to the built-in text and defaults, and a failed fetch never brings the stale cache back. A fetched setup that does not validate is never cached, so a corrected one at the same revision is still fetched. - wake-context shows owner_dm_room only while the owner-routing record is bound to the identity and gateway the running Sparrow reports, as the bridge requires; the gateway URL redaction moves to gateway_instance.redact_url so both read it one way. - Served commands must be the reply command with plain words: no shell syntax. - A served keepawake interval shorter than the installed task's cannot flag a normal gap. - self_upgrade, AUTO_UPGRADE and the hook's upgrade notice wake leave this PR.

Review from sutando-qingyun-001 (shared qingyun-wu login)
REQUEST_CHANGES at ffc65ca, for one item only: the REVIEW.md §15 live witness. The code is ready and I would approve it as is. The heartbeat payload is a live path, and the body says no post-restart round trip was run; that witness does not depend on the fetch transport. Owed: restart Sparrow on a Hatch agent at this code, and show one heartbeat carrying package_version accepted by the broker (health row still present), plus wake-context printing the built-in text. With that and license/cla green (close and reopen to retrigger), I'll approve at the same head. My three blockers from a08010d were all in self_upgrade.py. That file is now #5676, and I will review them there.
Split is clean. self_upgrade.py has been deleted. No AUTO_UPGRADE, wake-notice or upgrade-failed code is left, and the keepawake calls only _refresh_setup. setup-hint still stores target_version, but nothing reads it.
My order nit is fixed (runtime_text.py:166-175). Served text comes first, then restart_hint, then "These rules override anything above:", then the tier notes and the owner note last.
Kewei (3) is fixed. A cache is used only at the announced revision, and an invalid fetch is never cached.
Kewei (7) is fixed. owner_dm needs the identity, AGENT_MXID and redacted gateway to match. The redaction is the same one the bridge uses.
At head: served_setup 24 OK, hatch_adapter 166 OK (2 skipped), root shim OK, review-checks PASS. I skipped wheel_contents because it pip-installs build from PyPI. CI is 33 success and 3 skipped.
Mutations. Each line names the test that failed.
- Tier notes dropped:
cannot_drop_the_tier_notes. - Canonical notes put before the served text:
package_rules_come_last_after_any_served_end_marker. - PRECEDENCE line dropped: the same test.
- Stale
load_cachein place ofcurrent_cache:cli_prints_the_cached_textandserved_stuck_task_age. - Unvalidated fetch cached:
malformed_setup_is_never_cached. - owner-DM binding dropped:
owner_dm_bound_to_another_enrollment. - Clamp dropped:
out_of_range_values_are_clamped. - Interval floor dropped:
shorter_served_interval. - Loose command guard:
naming_another_command. - Not caught: wake-context calling
refresh_cache(the network). It is equivalent today because there is no transport. Add a fake-transport test that asserts wake-context never fetches.
Merge conditions
- license/cla is absent at ffc65ca. Close and reopen the PR to retrigger it.
- Capture one post-restart heartbeat round trip on dev, because the heartbeat is a live path. The risk is low: broker
post_heartbeatignores unknown keys. The witness does not depend on the setup transport.

Re-reviewed exact head ffc65caa149935dec0a581f238eb88936e1056c8. REQUEST_CHANGES. The self-upgrade split is clean and the stale-cache/invalid-fetch blocker is fixed, but two merge blockers remain.
-
The owner-DM binding still disagrees with the bridge for a changed enrollment.
owner_dm_room()redacts the persisted routing URL before comparing it togateway-status, while the bridge authorizes that persisted record only when its full URL equals the running URL. The status writer necessarily stores only the redacted URL. On this head, with the same agent identity, a routing record bound tohttps://gw.example/relay?enrollment=oldand a current status for the same redacted endpoint makesowner_dm_room()return!old-owner:ag2.space; the bridge's full comparison would reject that record after the enrollment query changed.wake-contextcan therefore direct a worker to a former enrollment's owner room. The new test covers a different host but not a changed credential/query on the same endpoint. The consumer needs a binding representation that can distinguish every gateway identity the bridge distinguishes. -
The required live-path witness is still absent. This changes the active heartbeat and installed hook prompt, and the PR body explicitly says no post-restart round trip was captured. Even without a setup-fetch transport, the current path can be exercised by restarting a Hatch Sparrow, showing the broker accepted a heartbeat containing
package_versionwith health intact, and showing the installed hook reacheswake-context/built-in text. PerREVIEW.md§15, unit coverage is not a substitute for that witness.
Local evidence otherwise passes: served setup 24/24, Hatch adapter 168 passed, 2 skipped, wheel contents, package drift, the review scanner, and git diff --check. Earlier self-upgrade findings belong to draft #5676, not this PR.
… URL, not its redacted form The bridge's owner-routing writer now stores a sha256 of the agent identity and the full gateway URL, query included, and the gateway status it already writes carries the same digest for the running Sparrow. wake-context shows owner_dm_room only when the record's identity and full URL digest equal the running Sparrow's. The redacted URL stays for display, so two enrollments that differ only in the query string no longer match. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

REQUEST_CHANGES at 3a55fd8. One new blocker, which this head introduced. The latest asks from both reviewers at ffc65ca are covered below, and I don't repeat them.
Blocker: the new binding field breaks an existing bridge test
At this head, refresh_routing() writes a binding key into the owner-routing record (packages/ag2-sparrow/ag2_sparrow/remote_gateway_bridge.py:1834-1836). The existing test at src/remote-gateway-bridge.test.py:1314-1316 compares that record to an exact dict: {"identity", "gateway", "owner_dm"}. It now fails with "the reading is persisted under the state dir, bound to this identity and this gateway". That failure is the cause of all three red checks at this head:
python standalone tests (3/9):FAILED: tests/remote-gateway-bridge.test.pynode + out-of-tree python tests: the same case,FAILED (1)tsc + tests (clean install): the aggregate gate
I reproduced it locally. I swapped in ffc65ca's remote_gateway_bridge.py and gateway_instance.py and ran the src suite: that case passes, and it fails at 3a55fd8. This host has 5 other env-dependent failures in that suite, the same at both revisions and unrelated to this case.
The PR body says the src suite "fails 4 cases on this host … CI is the reference for it". At this head CI fails on a case this change introduced, so that statement no longer holds.
Ask: update the assertion at src/remote-gateway-bridge.test.py:1314 to include "binding": gateway_instance.binding_digest("@agent-t:example.org", rtc.URL). Asserting the digest value is better than just allowing the extra key, because it pins the writer. Then confirm CI is green and update the body's test-plan line.
Earlier asks, checked at this head
- keweichen (1), owner-DM binding vs the bridge: fixed.
owner_dm_room()(adapters/hatch/runtime_text.py:54-69) now compares a sha256 of identity plus the full URL. The status file gets that digest from the bridge's own writer (remote_gateway_bridge.py:3603-3605).test_the_same_redacted_gateway_with_another_full_url_is_refusedcovers the same host with a different query, including a record written before the field existed. The test pins the fix: when I removed thebinding_digest(...) == bindingclause, exactly that test failed (27 ran, 1 failure). The bridge-writer subprocess test (test_hatch_served_setup.py:85-112) exercises the productionrefresh_routingand_emit_gateway_status, not a hand-rolled copy. - qingyun-wu merge condition 1, license/cla: resolved. The status endpoint shows 1 context,
license/cla success. - qingyun-wu nit, wake-context never fetches: still no fake-transport test. The CLI path calls
current_cache, notrefresh_cache(cli.py:1028-1029), so it is equivalent today. Non-blocking, as she filed it. - Live post-restart heartbeat witness (both reviewers): still owed. The body says none has been captured. Under my review rules this is named, not blocking. Both reviewers are holding their CRs on it.
What I ran
test_hatch_served_setup: 27 OKtest_hatch_adapter: 168 OK (2 skipped)tests/ag2-sparrow-hatch-served-setup.test.py: OKscripts/review-checks.sh --diff <pr diff>: PASS. My regex scan of added lines for hardcoded paths found nothing.- The mutation and the ffc65ca-vs-HEAD comparison described above.
Not verified: test_wheel_contents.py, because it pip-installs from PyPI. I did not run any live heartbeat or broker round trip.
— Sutando (susans-MacBook-Pro)
… key, never the URL 3a55fd8 persisted the raw gateway URL in owner-routing.json (as the bridge already did) and a plain sha256 of identity + full URL there and in gateway-status.json, both in the state dir, which may be synced. Now the bridge's existing routing writer stores the agent id, the redacted gateway URL and binding = HMAC-SHA256(per-install key, identity + full URL); the status file carries the same binding for the running Sparrow. The key lives in ~/.config/ag2-sparrow/binding.key (0600, outside the state dir), created by the bridge only. The bridge's reload and wake-context compare bindings through the one helper, gateway_instance.binding_digest; a record from before this change still reloads by its stored full URL.

…ey, under the config home The bridge suite pinned the routing record's old shape (raw gateway URL); it now pins the redacted URL plus the HMAC binding, with its key under a temporary config home. The key path follows XDG_CONFIG_HOME, else ~/.config, and only the owner-routing writer creates it, so the status writer and the reload never write outside the state dir.

Blocking finding: the live witness exposes a missing identity hop in both shipped Hatch launch paths, so this needs to be fixed in this PR rather than deferred.
install --mxid requires and persists the identity in Hatch config (adapters/hatch/cli.py:296-304,675-698), but the generated systemd environment contains only the device-env and task/result/state fields (cli.py:510-546), and detached _spawn_sparrow likewise copies the inherited environment plus selected config fields without cfg["AGENT_MXID"] (adapters/hatch/keepalive.py:208-225). The bridge does not read Hatch config: its resolver is process env, channel/device env, then prior durable enrollment (agent_identity.py:65-76). On a clean, documented token-only device env, the installed MXID therefore never reaches Sparrow.
That is exactly what the witness observed before the manual override: connected status had agent_id: null / gateway_binding: null, and wake-context had no owner_dm_room. The manual AGENT_MXID=<test agent> then works only because _spawn_sparrow starts from os.environ; it crosses the missing production boundary rather than testing it. Since this PR advertises installed wake-context resolving the owner DM through the running Sparrow's binding, this pre-existing launcher omission is now on the activated feature path.
Independent exact-head package repro (d788fbed99abf4b0c59a0de2b6440086bbd8dbf4) used a scratch HOME, wheel install, fake token-only device env, and /usr/bin/env in place of the child executable. The stock generated keepawake invocation spawned:
AG2_DEVICE_ENV=.../device.env
REMOTE_HEALTH_COMMAND=.../ag2-sparrow-hatch keepalive health
AGENT_CONNECT_TASK_DIR=.../tasks
AGENT_CONNECT_RESULT_DIR=.../results
AGENT_CONNECT_STATE_DIR=.../state
There was no AGENT_MXID; adding the witness's manual export made it appear. The focused service, detached-spawn, and owner-DM tests all pass (3/3), but they exercise those pieces independently and never assert that install --mxid reaches the launched bridge.
Please propagate the installed identity into both the generated user service and detached keepawake launch, pin both launch contracts, and add one clean token-only install-to-launched-bridge regression covering non-null matching identity/binding and wake-context's bound owner DM. Then rerun the final-SHA live witness through the stock path with no manual identity injection.
The rest of the posted witness is useful and passes the prior live-path gate: exact-head restart, accepted heartbeat/health, installed wake-context, healthy task/event channels, and one post-restart task/reply delivery still exactly once after 60 seconds. I do not treat the missing recipient-side DM readback as a separate blocker: the delivered proactive line is emitted only after a gateway-confirmed response with an event id, and the witness also checked zero shared-room copies. Recipient readback would still be worthwhile on the rerun if available.
Verdict: REQUEST_CHANGES until the stock Hatch identity path and its final-head witness are complete. Current CI and CLA are green at the reviewed SHA.
…and a revision has one spelling Install saves AGENT_MXID in its config, but neither the user service's environment nor the detached Sparrow the keepawake run starts carried it. Without it the bridge has no identity, so no gateway_binding and no owner_dm_room, and the owner-DM wording never activated on a normal install. `install_service` and `_spawn_sparrow` now read the saved value through `cli.saved_mxid`; with none saved (or not an MXID) they set nothing and print one NOTE line. A served setup's `revision` was accepted as an integer and cached as one, while the bridge's hint kept an announced `setup_revision` only as a `code_field` string token, so an integer revision was withheld on one side and never equal on the other. `gateway_credentials.revision_field` is the one normaliser (an integer that is not a bool is its decimal text, then code_field's rules); the bridge's hint writer and runtime_text's setup_problem, refresh_cache and current_cache all call it through diagnostics. The generated copies are regenerated from the canonical source. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Approving at 73c96b1b. It is our re-review after our approval at d788fbed; since then there is one fix commit (53123dc2) and a merge of main. The merge tree is byte-identical to a clean automatic merge of 53123dc2 and origin/main (git merge-tree against the merge commit gives an empty diff), so the review covers d788fbed..53123dc2.
1. The saved AGENT_MXID reaches the launched Sparrow (keweichen's CR at d788fbed). It is fixed on both launch paths:
install_serviceputsEnvironment=AGENT_MXID=…in the unit (adapters/hatch/cli.py:552-555), and_installpassesargs.mxid(cli.py:733)._spawn_sparrowsets it fromcfg["AGENT_MXID"](adapters/hatch/keepalive.py:214-218).- Both go through
saved_mxid, which returns''for missing or invalid values, so no identity is invented. Both print one NOTE when there is none.
2. One revision normaliser. gateway_credentials.revision_field turns a non-bool int into its decimal text, then applies code_field. It is in the canonical shared/ag2_gateway_credentials.py, and the two vendored copies are identical blobs. Every revision site uses it:
_record_setup_hint(remote_gateway_bridge.py:3667)current_cache,setup_problemandrefresh_cache(runtime_text.py:103,113,132)
A grep of the package, src/, skills/ and shared/ finds no other revision reader. The claude_code adapter already passes AGENT_MXID (claude_code/cli.py:141). The owner-DM wording is Hatch-only, so no other launcher has this gap.
Tests, run at the head in a scratch worktree.
- The five new or changed tests pass, and
tests/gateway-credential-sources.test.pypasses 132/132. - Each test fails when its fix is removed. I removed the unit's
AGENT_MXIDline (3 failures), the spawn'sAGENT_MXIDline (1), the bridge'srevision_fieldcall, back tocode_field(None != '41'), and the cache normalisation (41 != '41'). - These are behaviour tests. They read the generated unit, the environment a real stub child process sees, and the hint and cache that real
_post_heartbeatandrefresh_cachecalls write. None of them greps source. - On this host, 37
HookScript/HealthCommandcases intest_hatch_adapter.pyfail. The identical 37 fail atd788fbed, where CI was green, so they come from this host's environment and not from this diff.
CI: at this head, 35 checks pass and 3 are skipped. No review threads are unresolved.
Still owed (named, not blocking this approval):
- The REVIEW.md §15 live witness at this SHA, through the stock install and keepawake path with no manual
AGENT_MXID. The author says it is being re-run. - keweichen also asked for one token-only test from install to the launched bridge, showing the bridge's identity and binding, and the bound
owner_dm_roominwake-context. The new tests pin each launch contract on its own; that end-to-end test is not here. keweichen's change request stands until keweichen re-reviews. license/clais absent at73c96b1b: the status endpoint has 0 contexts. It wassuccessatd788fbed. A@cla-assistant checkhas been posted. Both commits are authored with the mapped noreply address.
Non-blocking note. code_field refuses any value that is a piece of a registered secret or that appears in the gateway URL. So small integer revisions will often be withheld: the new test itself pins revision_field(7) is None, a 1-digit value is almost always inside a hex token, and 2 is inside ag2.space. It fails closed, to the built-in text, so it is safe. The backend should still serve revisions that cannot collide, such as a prefixed or long token. It may be worth a line in the README.

Withdrawing my approval from 02:2xZ today at this same head (73c96b1b). I missed a defect that another reviewer's agent found, and I have now confirmed it in the code myself.
The detached keepawake path leaks an inherited identity (packages/ag2-sparrow/ag2_sparrow/adapters/hatch/keepalive.py:212-218):
_spawn_sparrowbuilds the child env asdict(os.environ, ...). Whensaved_mxid(...)returns nothing, theelsebranch only printsNO_SAVED_MXID.- Any
AGENT_MXID/AGENT_IDalready in the caller's environment therefore passes straight through to Sparrow. Sparrow can run as a different agent while the NOTE says no identity was saved. - That contradicts the PR's own claim ("when none is saved, nothing is invented").
- The user-service path (
adapters/hatch/cli.py:551-555) is not affected. It builds a freshenv = {...}dict, so the two launchers now disagree.
Asks
- In
_spawn_sparrow, dropAGENT_MXIDandAGENT_IDfrom the inherited env before the saved value is applied (pop both in theelsebranch; also popAGENT_IDwhen a saved MXID is set, so the two can never disagree). - Add a test that runs a real child with a foreign
AGENT_MXID/AGENT_IDin the parent env and no saved MXID, and asserts the child sees neither. It must fail at73c96b1b.
Everything else from my previous review still stands: revision_field is verified, the tests fail with their fix lines removed, and CI is green. Still owed: the §15 live witness, Kewei's end-to-end token-only test, and license/cla (0 contexts at this head).

Reviewed exact head 73c96b1b9d2ba14897e100476ad270ffd2f33dd8 after the merge from main. The two happy paths are improved, but this head is not merge-ready.
What I verified:
- A validated saved
AGENT_MXIDreaches a newly spawned detached child and the rendered service unit. I found no shell/systemd quoting injection in that value path. revision_fieldcorrectly maps a non-bool integer to decimal text, rejectsbool/float/None, and the generated copies are in sync. A freshly fetched integer revision is stored as a string.- Exact-head focused suites passed: Hatch adapter 200 (2 skipped), served setup 108, credential sources 132, both drift checks,
diff --check, and the review hardcoded-path scan. Current Actions are green.
Blocking findings:
-
The absent/malformed saved-identity path can still launch Sparrow as an ambient identity.
_spawn_sparrowcopies all ofos.environand only overwritesAGENT_MXIDwhen the saved value validates. It never removes inheritedAGENT_MXIDor the acceptedAGENT_IDalias (resolver, precedence). With an ambient value injected after the test module's import-time environment cleanup, the real child probe produced:saved=None actual=@ambient:ag2.space expected=unset saved=not-an-mxid actual=@ambient:ag2.space expected=unset saved='' actual=@ambient:ag2.space expected=unsetAn ambient
AGENT_IDlikewise reached the child, while the command printed the NOTE claiming that Sparrow runs with no identity. The current test hides this because it sanitizes the outer environment at module import. Clear every process identity alias before optionally applying the validated saved value, cover both aliases, and give the service-unit path the same no-inheritance contract. A wrong inherited identity is materially worse than no identity: it can bind the bridge and owner-DM routing to the wrong agent. -
current_cachestill bypasses the shared revision normalizer.current_cachecallsrevision_fieldonly when an announcement exists, then returns the original cache object. With no hint, malformed values (True,41.0,None,"rev 41") are accepted; a registered synthetic secret also reachedwake_context's source string:normalizer None current_cache_accepted True wake_source served revision synthetic-secret-5665With an announcement, a legacy integer compares via the normalizer but is still returned as
int;refresh_cache's early return leaves that integer on disk. Normalize cached revisions unconditionally before any usable return, reject aNonenormalization even without a hint, and pin whether legacy integer files are rewritten or only normalized in memory. The current rendered-text assertion cannot distinguish41from"41". -
The required REVIEW.md §15 evidence is not yet at this head. The only posted live witness is at
d788fbed, and it explicitly injectedAGENT_MXIDby hand. Please post the frozen-current-head, real post-restart bridge/binding/owner-DM round trip without that injection before requesting approval.
I am treating the already-disclosed behavior of an older still-running Sparrow retaining its old/null identity until restart as the stated limitation, not adding it as a separate blocker in this round.
… and every cached revision is read normalised The detached launch built the child's environment from its own, so with no saved AGENT_MXID a caller's AGENT_MXID or AGENT_ID passed through and the bridge, whose resolver reads the process env first, ran as that identity. `_spawn_sparrow` now removes every key in `agent_identity.ENV_KEYS` in every branch and sets only the validated saved MXID. A user unit inherits the user manager's whole environment, so the unit writer gains `UnsetEnvironment=` for the identity keys it does not set; it is applied after `Environment=`, so the saved identity is never also unset. `current_cache` normalised a cached revision only against an announcement and otherwise returned the raw cache, so a no-hint cache with a bool, float, missing, malformed or secret revision stayed usable and a legacy integer stayed an integer. `runtime_text.cache_revision` is now the one reader, with the registry and the redacted gateway URL Sparrow reports: `current_cache` normalises before the comparison and returns a copy whose revision is text, and a revision that does not normalise reads as no cache. `keepalive main` registers the device secrets before any cache is read, as wake-context does. An end-to-end test runs the shipped install and the real spawn with a stand-in Sparrow that is the real bridge module (only the gateway call is faked), from an environment carrying a foreign identity in both resolver keys: the launched bridge binds as the installed identity and wake-context names the owner DM; with no saved identity it binds as nobody and wake-context names no room.

Reviewed exact head f091c7235c48558cf3e46f6b797f34cc4ff6761e (direct parent 73c96b1b9d2ba14897e100476ad270ffd2f33dd8). The two findings from my previous review are fixed for the inputs the new tests exercise: direct AGENT_MXID / AGENT_ID inheritance is removed, the rendered systemd Environment= / UnsetEnvironment= forms are correct, and every usable cached revision now passes through the shared normalizer. The focused suites, generated-copy checks, drift checks, git diff --check, and the review scan pass. However, this head is still not merge-ready.
Blocking: the “saved identity or none” launch contract covers only the first resolver tier
_spawn_sparrow copies the caller's full environment, removes only agent_identity.ENV_KEYS, retains CLAUDE_CONFIG_DIR, and explicitly passes AG2_DEVICE_ENV. The bridge then re-resolves identity through process env, every FILE_KEYS alias, and durable enrollment, in that order. Its file candidates are AG2_DEVICE_ENV and $CLAUDE_CONFIG_DIR/channels/<dir>/.env. _reenroll_identity() still consumes that whole chain.
Using only synthetic temp files/state, I ran the exact-head _spawn_sparrow with a real child that imported the shipped resolver. With no saved MXID, direct aliases were gone but a foreign identity still won from the inherited caller config:
NOTE sparrow: the install config holds no AGENT_MXID, so this Sparrow runs with no agent identity ...
{"direct_AGENT_ID": null,
"direct_AGENT_MXID": null,
"resolved_identity": "@foreign-from-caller-config:ag2.space"}
Removing CLAUDE_CONFIG_DIR did not close it because the launch itself supplies AG2_DEVICE_ENV:
{"direct": [null, null], "resolved": "@foreign-device-file:ag2.space"}
With both file tiers empty, the same exact-head resolver returned the synthetic durable record:
resolve(empty_process_env, empty_channel_files) -> @foreign-durable:ag2.space
The unit path has the same semantic hole. UnsetEnvironment=AGENT_MXID AGENT_ID correctly filters manager-provided variables, but cannot remove aliases inside the explicitly passed device file, the retained channel file, or the durable record. Applying the rendered unit's final environment in a hermetic probe produced:
direct AGENT_MXID=None AGENT_ID=None
resolved_identity=@foreign-unit-file:ag2.space
This contradicts NO_SAVED_MXID and the commit's “runs only as the saved identity” contract. It preserves the same material failure at a different input tier: a foreign identity can create the gateway binding and select that agent's owner-DM routing instead of leaving Sparrow unbound.
The new tests do not cover these adjacent inputs. The detached child assertion observes only the two direct variables, while the end-to-end case uses a token-only device file, fresh state, and --no-service. Please make the Hatch launch's validated saved identity—or authoritative explicit absence—apply to the full shared identity-resolution chain, not only its process-env tier. Pin every FILE_KEYS alias in both file candidates plus a pre-existing durable identity, for saved and no-saved launches, and exercise both the detached and systemd-shaped final environments. Clearing only CLAUDE_CONFIG_DIR is insufficient and would also conflate identity policy with unrelated channel configuration.

The required REVIEW.md §15 live restart/round-trip witness is also not yet posted for f091c723; the only posted witness remains the older d788fbed run with identity injected manually. Any corrective commit will of course require that witness at the new final SHA.

Approving at f091c723. This re-review follows my change request at 73c96b1b. One commit sits on top of it. I checked each claim in the code and by running the tests in a scratch worktree.
1. No inherited identity on either launch path (my CR asks 1 and 2, and keweichen's finding 1).
- Detached path:
_spawn_sparrowpops every key inagent_identity.ENV_KEYS(AGENT_MXID,AGENT_ID) before it applies the saved value (adapters/hatch/keepalive.py:215-216). This happens in every branch, so with a saved MXIDAGENT_IDis gone too. - User-service path:
install_servicewritesUnsetEnvironment=for each identity key that the unit does not set itself (adapters/hatch/cli.py:562, rendered atcli.py:390). - The systemd semantics are right.
UnsetEnvironment=is applied afterEnvironment=, so a name listed in both would be removed. The savedAGENT_MXIDis kept out of the unset list, and the test pins that. _spawn_sparrowis the onlyPopenin the Hatch adapter.replace_sparrow,ensure_sparrowand install's start all go throughrestart_listener, which uses either the unit or_spawn_sparrow.- In the package and
src/, the otherdict(os.environ…)sites are masking registries (cli.py:146,1126) or launchers outside this PR's diff.
2. One cache-revision reader (keweichen's finding 2).
cache_revision(adapters/hatch/runtime_text.py:97) is applied unconditionally incurrent_cache, which returns the normalised revision (:119). It is also used insetup_problemand in therefresh_cachewrite (:147).wake-contextand the health row's tunables both read the cache throughcurrent_cache.keepalive mainnow registers the device secrets (keepalive.py:664), so the rule there withholds this host's secrets.
3. Tests: they pass at the head and fail at 73c96b1b.
- At
f091c723, all 7 new or changed cases pass. The fulltest_hatch_adapter.pypasses 203/203 (2 skipped) andtest_hatch_served_setup.pypasses 109/109.tests/gateway-credential-sources.test.pyandtests/ag2-sparrow-hatch-served-setup.test.pypass.git diff --checkis clean, and the hardcoded-path scan of the added lines is clean. - Correction to my last review: the 37
HookScript/HealthCommandfailures I reported came from this host's interpreter path, which contains a space and breaks a stub's shebang. The PR did not cause them. With a space-free interpreter path, nothing fails. - I then put the
73c96b1bversions ofcli.py,keepalive.pyandruntime_text.pyback and kept the new tests. All 7 cases fail, with 22 failures and 1 error:- The unit has no
UnsetEnvironment=. - The real child sees
@caller-agent_mxid… @caller-agent_id…instead ofunset unset, and sees the caller'sAGENT_IDnext to a saved MXID. - The cache accepts
True,41.0, a missing revision,"rev 41", a registered secret and gateway-URL text, and keeps41as an int. - The tunables-only cache still applies.
- The unit has no
- keweichen's end-to-end test (
tests/test_hatch_adapter.py:2538) works as follows:- It runs a token-only
install --mxid. The bridge is real (its own resolver,refresh_routingand_emit_gateway_status; only_reqis faked), andwake-contextnames!dm:ag2.space. - The caller's shell carries another agent's identity. With no saved MXID, the bridge's status reads
agent_id: nullwith no binding. - At
73c96b1b, the bridge comes up as@caller:ag2.spacewith a binding. I saw this after waiting 15 s. The unmodified test fails earlier, because the status file is not yet written. - It passed 5/5 at the head.
- It runs a token-only
CI and threads. At this head, 35 checks pass and 3 are skipped. No review threads are unresolved.
Still owed (named, not blocking this approval):
- The REVIEW.md §15 live witness at this SHA, run through the stock install and keepawake path with no manual
AGENT_MXID. The author says it is being re-run. license/clais absent atf091c723: the status endpoint returns 0 contexts. A@cla-assistant checkwas posted at 03:28Z.- keweichen's change request stands until keweichen re-reviews.
Non-blocking notes.
- (a) Only the end-to-end test's second half runs through keepawake, and that path does not wait for "connected". Its status read depends on the bridge writing within
SPAWN_SETTLE_S(3 s). A short poll would make it robust. - (b) A legacy integer revision is normalised in memory only. The
refresh_cacheearly return leaves41on disk. That is safe, but no test pins it either way. - (c) A unit written by an earlier install has no
UnsetEnvironment=until install is re-run. - I did not run the tests at
d788fbed.

…er tier, and a legacy cached revision is written back as text The Hatch launchers removed only the process-env identity keys, so a Sparrow launched with no saved AGENT_MXID still resolved an identity from a later tier: an AGENT_MXID / AGENT_ID / AG2SPACE_USER_ID alias in the device env file or the inherited channel .env, or the durable state/auth/ag2space.json binding. The policy now lives in the resolver. agent_identity.resolve honours a launch pin (AG2_IDENTITY_PINNED): a pinned environment answers from its own AGENT_MXID alone, so a pinned bridge runs as the saved identity or as none at every tier. launch_environ / pinned_environ are the one way a launcher builds that environment; the detached spawn and the systemd unit both use them. Channel config (CLAUDE_CONFIG_DIR, AG2_DEVICE_ENV) is unchanged: only identity is pinned. The re-enroll log no longer tells a pinned bridge to write its identity into a channel .env, which it would now ignore. Tests pin each tier for saved and no-saved launches through the bridge's own resolver: every FILE_KEYS alias in both file candidates and a durable record, under the detached child's real final environment and the rendered unit's final environment; the token-only end-to-end test plants all of them and waits for the bridge to report connected instead of a fixed settle. A cache an older build wrote with an integer revision is now rewritten with the text revision. Stand: Echo Act IV Pro Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Approving at cad22997. This re-review follows my approval at f091c723 (review 5636711143) and covers the one commit on top of it, which answers keweichen's change request about the later resolver tiers. I checked each claim in the code and by running the tests in a scratch worktree.
1. The pin closes every resolver tier (keweichen's finding at f091c723).
agent_identity.resolvereturnsenv["AGENT_MXID"]alone whenAG2_IDENTITY_PINNEDis set, before theENV_KEYSloop, theFILE_KEYSfile tier andenrolled()(packages/ag2-sparrow/ag2_sparrow/agent_identity.py:84-85). So a pinned bridge never readsAGENT_ID, a file alias inAG2_DEVICE_ENVor the channel.env, orstate/auth/ag2space.json.- Every identity read in the bridge goes through
_reenroll_identity()->resolve(remote_gateway_bridge.py:2164): routing, owner DM, statusagent_id/gateway_binding, profile push, re-enroll. The two direct reads (remote_gateway_bridge.py:7527,:7551) read processAGENT_MXID/AGENT_IDonly, whichlaunch_environhas already reduced to the saved value. - Repo-wide grep of
AG2SPACE_USER_ID,ag2space.jsonandFILE_KEYS: inside the package onlyagent_identity.pyreads them. The other readers (src/entrance_links.py,src/runtime-api/identity_view.py,src/runtime-api/rundir.py,skills/pending-questions/) belong to the core, not to the launched bridge. - Both launch paths use the new builders. The detached path calls
launch_environ(os.environ, mxid)(adapters/hatch/keepalive.py:215). The unit path callspinned_environ(saved_mxid(mxid))(adapters/hatch/cli.py:557), which rendersEnvironment=AG2_IDENTITY_PINNED=1and keepsUnsetEnvironment=for the identity keys the unit does not set._spawn_sparrowis still the onlyPopenin the Hatch adapter.pinned_environis the only writer of the key in the repo. - Unpinned behaviour is unchanged. Without the key,
resolveruns the same chain as before, and the tests' unpinned control shows each planted tier still wins. - The re-enroll log is changed: a pinned bridge with no identity logs "launcher pinned no agent identity … RESTART it" instead of telling it to write the identity into a channel
.env(remote_gateway_bridge.py:2181-2184).
2. Tests: they pass at the head and fail when only the pin check is removed.
- At
cad22997, each module run on its own:test_hatch_adapter206 OK (2 skipped),test_hatch_served_setup109 OK,tests/ag2-sparrow-agent-identity.test.py13 OK,tests/gateway-auto-reenroll.test.py40 OK,tests/gateway-credential-sources.test.py132 OK,tests/ag2-sparrow-hatch-served-setup.test.py109 OK. The token-only end-to-end test passed 3/3 when run alone.git diff --checkis clean, and the hardcoded-path scan of the added lines is clean. - With only the two pin lines removed from
resolve(everything else at the head): agent-identity fails 9 (8 tier subtests plus the pin-contract test),test_hatch_adapterfails 25 (8 detached-path tiers, 16 unit-path tiers, and the end-to-end test, where the bridge reports@caller:ag2.space), andgateway-auto-reenrollfails 1 (the pinned no-claim test). That matches the claimed 9 + 25 and adds one. Every tier failure is the no-saved case; with a saved MXID the env tier already wins. - The tests go through the bridge's own
_reenroll_identity. Each tier is planted alone and then all of them together: everyFILE_KEYSalias in both file candidates, plus the durable record. They run under the detached child's real final environment and under the rendered unit's final environment with the manager's identity keys applied.
3. My two minor notes are fixed.
- (a) The end-to-end test now polls
gateway-status.jsonfor up to 30 s until it readsconnected(test_hatch_adapter.py, the keepawake half), instead of relying on the 3 s settle. - (b)
refresh_cachenow writes a kept cache back when its spelling differs, so an integer41becomes"41"on disk with mode 0600. A cache already spelt as text is not rewritten (adapters/hatch/runtime_text.py:138-142). The test pins both cases.
CI and threads. At this head, 35 checks pass and 3 are skipped. No review threads are unresolved.
Still owed (named, not blocking this approval):
- The REVIEW.md §15 live witness at this SHA, run through the stock install and keepawake path with no manual
AGENT_MXID. None is posted atcad22997. license/clais absent atcad22997: the status endpoint returns 0 contexts. A@cla-assistant checkwas posted at 04:05Z.- keweichen's change request stands until keweichen re-reviews.
Non-blocking notes.
- (a)
_on_task_envkeepsAG2_IDENTITY_PINNED, so wake-command children inherit the pin. A descendant that runs the claude-code installer (adapters/claude_code/cli.py:151) would resolve from envAGENT_MXIDalone and ignore its token file's identity. Today that only matters when no MXID is saved. Strip the key there, or say this is intended. - (b) Any non-empty value pins,
"0"included (agent_identity.py:84). Only the launchers set it, so this is harmless, but== "1"would match how the key is written. - (c) This one is not caused by this PR, and the same thing happens at
f091c723. Whentest_hatch_adapterandtest_hatch_served_setuprun in one interpreter, 4Diagnostics/InProcessSinkstests fail because secrets registered by the first module leak into the second. Run separately, both pass.

Reviewed exact head cad2299. APPROVE; this replaces my stale f091c72 change request.
The blocker is fixed at the policy owner. agent_identity.resolve now treats a launch pin as authoritative and reads only the saved AGENT_MXID or none; launch_environ and pinned_environ feed the detached and systemd-shaped launch paths without dropping unrelated channel configuration. The regression matrix exercises every identity alias in both file candidates plus durable enrollment, for saved and no-saved launches, with unpinned controls. Removing only the resolver pin branch produced 9 failures in the identity suite and 25 failures in the Hatch suite, including the real-child no-identity case.
Exact-head verification passed: agent identity 13, auto-reenroll 40, credential sources 132, served setup 109, and Hatch adapter 206 with 2 macOS /proc skips. The cache rewrite is atomic through the existing writer, preserves mode 0600, and its mutation is caught. Review checks and diff check are clean. Independent QA found no production defect.
The exact-head REVIEW.md section 15 witness is now posted at #5665 (comment). It used the package installed from this SHA through the shipped Hatch path, restarted a verified process into a new pid, then carried a real team-room task through accepted reply and exactly one DeliveryCore delivery after 60 seconds. It also verified the saved identity and pin, ignored decoy channel and durable identities, matching binding, connected task/event channels, and owner-DM wake context. Actual systemd execution, a live device-env decoy, null saved identity, and live integer-revision normalization remain correctly labelled as harness or unit coverage.
Worst case: a legacy Hatch config with no valid saved MXID now fails closed as unbound instead of inheriting a device, channel, or durable identity; owner-DM resolution stays unavailable until the operator saves the MXID and restarts. The explicit NO_SAVED_MXID warning and corrected reenrollment guidance make that recovery path clear. Existing units and already-running bridges acquire the new pin only after reinstall/restart, as the author notes.
All 35 current Actions checks pass and 3 platform/release jobs are skipped. The commit-status endpoint still has zero status contexts, so license/cla is absent rather than failing; do not merge until that required gate appears and is green.

Conflicts resolved as unions: main's served runtime text (#5665) and the hold work both stand. The health row keeps main's served tunables (hook_silent_age_s, stuck_task_age_s) around open_tasks; the built-in worker_note gains the hook script's hold sentence so the two stay equal; two new exception sinks go through diagnostics.describe; the served-setup health tests patch open_tasks, which replaced oldest_open_task; valid_pid, added on both sides, is defined once in the outbox.

…hen a heartbeat announces a new revision (#5855) * feat(ag2-sparrow): Sparrow fetches its served setup from the broker when a heartbeat announces a new revision #5665 taught the Hatch adapter to read the agent.setup.steps payload, but setup_fetch had no transport, so nothing in a running Sparrow fetched it. Sparrow holds the gateway bearer, so the bridge fetches: when a heartbeat reply's setup_revision differs from the copy it holds, setup_fetch.Refresher GETs the broker's /v1/setup through the bridge's _req (10 s deadline), validates the whole result (schema_version 1, the announced revision, this agent, text_schema_version 1 with all four listener blocks or none, size cap), and only then replaces state/served-setup[.<instance>].json via the bridge's durable writer. Any failure or refusal writes nothing, keeps the last good copy, and backs off 60 s doubling to 1 h; an unchanged revision is a no-op. The keepawake run's refresh_cache reads that copy through fetch_setup. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(ag2-sparrow): run the setup-fetch suite under repository coverage; pin the two failure guards The package suite ran only in the out-of-tree step, which coverage does not measure; tests/ag2-sparrow-setup-fetch.test.py runs it under coverage, as the Hatch served-setup wrapper already does. Two new tests pin behaviour that was untested: a writer that raises is a failed fetch that keeps the last good copy and never reaches the heartbeat, and an unreadable identity still lets the heartbeat succeed and the fetch proceed without the agent_mxid check.

Reason: the ag2-sparrow side of serving agent wording from the backend; the self-upgrade part moved to a stacked follow-up.
Closes
N/A (proposal, no issue).
Stacked PR
N/A for this PR, which is based on
main. The self-upgrade that was in earlier revisions is now #5676, a draft stacked on this one.Summary
The Hatch worker's wording can now be served by the backend, with the package's copy as the fallback.
package_version in the heartbeat.
_post_heartbeatsendspackage_version. The reply'ssetup_revision,min_versionandtarget_versiongo tostate/setup-hint[.<instance>].jsonthrough the bridge's durable writer, best-effort. Sparrow never acts on them.ag2-sparrow-hatch wake-context. Prints the prompt, worker note and restart hint a woken worker follows. They come from the setup cachestate/hatch-setup.json, else frombuiltin-runtime-text.json(today's prompt and worker note verbatim). The built-in copy applies in each of these cases:text_schema_versionis newer than 1<REPLY_COMMAND>followed by plain words (no;,|,&,$or the like)setup_revisionSparrow last heard announcedPackage rules come last. Served
tier_addendacome next. Then come the package's tier note and owner note, after "These rules override anything above:". So nothing served can follow them, and served text cannot remove them. The owner note reads: "To reach your owner, post only in your owner's AG2 Space DM; never use another channel."owner_dm_room. After the owner note,
wake-contextprintsowner_dm_room: <room id>only when Sparrow'sowner-routing[.<instance>].jsonrecord has the same binding as the running Sparrow.HMAC-SHA256(per-install key, agent identity + full gateway URL, query included). One helper,gateway_instance.binding_digest, computes it for the bridge and forwake-context.<home>/.config/ag2-sparrow/binding.key, where<home>is the effective uid's passwd home asholder_lockresolves it (throughtask_io.user_home(), which stays the one module importingholder_lock), never an environment variable. So a systemd unit, the Hatch hook and a shell all resolve one key. It is mode 0600 and outside the state dir, which may be synced. Only the bridge's owner-routing writer creates it.os.linked into place, so it appears whole or not at all. If the link hits EEXIST, the key already there is used. Every writer re-reads the key under the lock before binding with it, so two writers recovering a bad key end up with one key.routing_migrationsrewrites it into the bound form; see the contract below. So a cold upgrade with no key keeps the owner DM and no longer leaves the URL on disk.hmac.compare_digest, and so doeswake-context.Gateway URL text: see the contract below.
Tier notes have one owner. The built-in tier note is
task_io.non_owner_note(), the same text the hook reads.builtin-runtime-text.jsonno longer carries a copy.AGENT_MXID, and the room id must be valid. The bridge has no separate enrollment id, so the agent id plus the full URL under the per-install key is what identifies an enrollment.Hook prompt stub.
hook-definition.json's prompt tells the worker to run<REPLY_COMMAND> wake-contextand follow it, together with the payload'sworker_note. If that command fails, it follows theworker_notealone. Install prints the usualREQUIRED hook:line for the changed definition.Cache and fetch.
setup_fetch.fetch_setup(kind="acp", vendor="muse")is the one boundary, with a pluggable transport. The package has no client for theagent.setup.stepsAction, so no transport is installed: fetch returns None and the built-in text and defaults apply.Tunables, clamped.
keepawake_interval_s[300, 3600]stuck_task_age_s[300, 7200]hook_silent_age_s[120, 3600]heartbeat_cadence_s[30, 90] (clamped but unused yet)Out-of-range values are clamped and logged. A served keepawake interval shorter than the installed 15-minute task cannot flag a normal gap.
Contract: the gateway URL and the routing migration
This follows the design note in the PR comments: the sinks are the boundary, and the migration keeps no latch.
1. Sinks take structured safe fields only.
file:line), the redacted gateway identity, and text the code wrote. It never gets an exception's own text, a response body, or gateway-supplied free text. Behaviour code may still read an HTTPError body for control flow.ag2_sparrow/diagnostics.py:describe(exc)is how any exception reaches a sink.code_fieldadmits a gateway-supplied token (an error name, an approval code) only when it is short, made of letters, digits and_.-, absent from every form of the URL, and neither holds a registered secret nor is a piece of one. Every comparison is case-folded on both sides: a token is case-sensitive as a credential, but an echo of it in another case still reveals it.version_fieldadmits a gateway-supplied version only when it is a PEP 440 version of at most 64 characters that holds no registered secret.safe_statuspasses every nested string of the status payload throughredact_textand then the secret registry, and withholds non-JSON values and non-finite numbers.refused_errorand the approval code survive only ascode_fieldtokens.diagnosticsholds every secret of the process: each credential part of the gateway URL (the whole userinfo, the username, the password, the query values, the fragment), the bearer token, the media token and any token read from a file. The Hatchwake-contextand install commands register the bearer and URL from the device env too. Logs, status values, the setup hint, the owner DM and the excepthooks withhold text holding any of them in any rendering and any letter case.code_fieldrefuses a value that holds one or is a piece of one, so an echoed bearer is neither an error name nor an approval code. Tokens are matched at any length. A bare URL piece (userinfo, username, password, query value, fragment) shorter than 8 characters is not matched alone, since it would withhold ordinary words; its delimited form (=value,user:pw@,#frag) is matched at any length. A very short token therefore withholds every line holding its characters: the chosen fail-closed cost.gateway_instance.gateway_call, which re-raises what they raise as the same type with only<Type> contacting <redacted gateway>[ (HTTP n)]as text. Nested exceptions are scrubbed, and there is no__context__. The event channel and the card poster keep only the type.redact_textand the secret registry both run inside_logand on every status value; status keys, the payload's own field names, go throughredact_textonly.redact_textmatches the URL's scheme and host in any case and its credential parts case-folded. The scrubbingsys.excepthook,threading.excepthookandsys.unraisablehook(which an exception in an atexit callback also reaches) scrub every piece of their record (thread name, file name, type, text) and withhold the whole record if a secret spans the pieces.setup_revisiongoes tosetup-hint.jsononly as acode_fieldtoken and its versions only as PEP 440; the payload then runs throughsafe_statusand is written with NaN and infinity refused. The owner DM room (from/v1/agents, the routing record, the withheld-review cache or a created room) is kept only as a strict Matrix room id on the agent's own homeserver that holds no registered secret and whose localpart, if 6 characters or longer, is no piece of one (code_field's piece rule), checked by one function,gateway_instance.owner_room, when it is stored and again beforewake-contextprints it. This assumes the owner DM lives on the agent's own homeserver: a room id on another server, or one with no server part (room version 12), is refused, and the owner DM then stays unresolved until the gateway answers with one on the agent's server.describe,code_field,type,intor.code. A sink is a sink function (_log,log,_log_backoff,print, a stream write, a status writer) or any call handed one by name as an argument (report_once(key, _log, line)), whose other arguments it checks. It follows that text through local text assignments (msg = f"{e}", an aliased body, a_reqanswer) and one hop into a same-module helper's parameter, in line order, so a later clean assignment ends it. It does not follow values across modules, through containers or object attributes, through return values, or a sink function stored and called under another name. Inside a callee that receives the bridge's_logbut lives in a vendored core module (result_disposal,undelivered_quarantine) or the monorepo's HITL handlers, exception text formatted there passes only the_lognets (redact_textand the registry), not the structured rule.

Main had the same gap; this PR owns the credential name set, so it is fixed here, in the owner.bridge_strip_keys()insrc/gateway_credential_sources.pyreturnsTOKEN_KEYS + (MEDIA_TOKEN_KEY,):REMOTE_TASK_TOKEN,AG2_REMOTE_TOKEN,REMOTE_MEDIA_HS_TOKEN. Vendored byte-identical (sync_from_src.py --checkin sync).bridge_environfilters sparrowd's environment onHOST_ONLYand that set, then mergesbridge_token_environ(token)whole as before. No adapter changed.bridge_strip_keysjoinsREADER_ONLY(named only by the reader, only as a call on the owner's import); the pinnedbridge_environbody is the new one; three reader mutants that narrow the set again (strip = token_env,HOST_ONLY + tuple(token_env),bridge_strip_keys()[:1]) are flagged; the owner behaviour test asserts the tuple, that it equalsset(TOKEN_KEYS) | {MEDIA_TOKEN_KEY}, and that it covers the name the agent's token goes under.tests/sparrowd-agent-bridges.test.py, classWrapper, synthetic values):bridge.mainruns the bridge with a host value under all three names; one test per key asserts the host'sREMOTE_TASK_TOKENis replaced by the agent's, andAG2_REMOTE_TOKENandREMOTE_MEDIA_HS_TOKENare absent from the environment the bridge module runs under (key and value). A fourth drivesbridge_environdirectly overbridge_strip_keys()so a name added to the owner's set later is covered without editing the test.The
AG2_REMOTE_TOKENitem listed in the comment on #5820 is fixed here; the issue's two guard-completeness gaps (shutil.copyfile, aliasedenviron.update) remain its own.Before/after, the new sparrowd tests with

f091c7235)1. The detached launch is fail-closed on identity. At 73c96b1
_spawn_sparrowbuilt the child's environment from its own, so with no savedAGENT_MXIDa caller'sAGENT_MXIDorAGENT_IDpassed through and the bridge's resolver, which reads the process env first, ran as that identity.keepalive._spawn_sparrownow pops every key inagent_identity.ENV_KEYS(AGENT_MXID,AGENT_ID: the resolver's own env tier, read from that tuple) in every branch, then sets only the validated savedAGENT_MXID.test_a_started_sparrow_runs_as_the_saved_agent_mxid_and_gets_no_default_without_onelaunches from an environment carrying foreign values in both keys and reads what a real child sees: the saved MXID and noAGENT_IDwhen one is saved; neither when the saved value is absent, empty or malformed, with the NOTE printed.2. The unit path has the same no-inheritance contract. A user unit inherits the user manager's whole environment block, so leaving
Environment=AGENT_MXID=out was not enough.render_servicetakesunset, written asUnsetEnvironment=, which systemd applies last, afterEnvironment=. With a saved MXID the unit carriesEnvironment=AGENT_MXID=<saved>(which beats the manager's value) andUnsetEnvironment=AGENT_ID; with none it carriesUnsetEnvironment=AGENT_MXID AGENT_IDand no identity. A name set byEnvironment=is never also inunset. Tests:test_the_unit_carries_the_saved_identity_never_the_installers_ambient_one(both keys ambient in the installer's environment) andtest_the_unit_gets_no_agent_mxid_when_none_was_saved_and_says_so(both keys ambient; empty, malformed and padded saved values) pin both lines and the absence of the ambient values.3. Every read of a cached revision goes through
revision_field. At 73c96b1current_cachenormalised only when an announcement existed and otherwise returned the raw cache, so a no-hint cache with a bool, float, missing, malformed or secret revision stayed usable and a legacy integer stayed an integer.runtime_text.cache_revision(cache, gateway_url)is now the one reader:current_cachenormalises before the comparison and returns a copy whoserevisionis always text; a revision that does not normalise reads as no cache, announcement or not;setup_problemandrefresh_cacheuse the same reader. The registry supplies the secret and secret-piece rules; the redacted gateway URL from Sparrow's status file supplies the URL-text rule (host, path), andregister_gateway_urlthe credential parts.keepalive mainregisters the host's device secrets before any cache is read, aswake-contextalready did. Test:test_a_cache_with_no_announcement_is_read_only_through_revision_field: bool, float, missing, malformed text, a list, a registered whole secret, a registered piece, a URL query value, a URL fragment, the host (both cases) each read as no cache, reachwake_contextas the built-in text and leave no secret in the text or source; a legacy integer reads as"41"(assertIsInstance(.., str)) and a text revision as itself; the health row's tunables read the same way.4. The end-to-end regression Kewei asked for:
test_a_token_only_install_binds_the_launched_bridge_and_wake_context_resolves_the_owner_dm(inStartSparrow). A clean home holds only the relay token file (url|secretform) and the runner's environment carries another agent's identity in both resolver keys.ag2-sparrow-hatch install --mxid … --no-serviceruns the shipped install and the real_spawn_sparrow, which starts a stand-inag2-sparrowthat is the real bridge module: its identity comes through the bridge's own resolver and its credentials through the device-file tier; only_reqis faked (a/v1/agentsanswer with a row for the installed agent and one for the caller's identity), and it runs the realrefresh_routingand_emit_gateway_status. Asserted: install returns 0 withstarted:,gateway-status.jsonhasagent_id= the installed MXID and a non-nullgateway_binding, and the installedwake-contextprintsowner_dm_room: !dm:ag2.spacewith nothing of the caller's. Then the same chain with no saved identity (the config stripped ofAGENT_MXID, status and routing removed, bridge stopped):keepalive keepawakerestarts the bridge, which reportsagent_idnull andgateway_bindingnull, writes no routing record, andwake-contextprints noowner_dm_room:at all, with the NOTE on stderr. Against the old production code, with this test file:keepalive.pyandcli.pychecked out from 73c96b1 under this test file: it fails on the no-saved case (gateway-status.jsonreportsagent_id@caller:ag2.space, the runner's identity); from d788fbe: it fails on the saved case already (agent_idis the caller's, not the installed MXID, since the saved value never reached the bridge). The no-hint cache test against 73c96b1'sruntime_text.pyfails 13 subtests: every bad shape (bool, float, missing, malformed text, a list, the whole secret, its piece, the URL query value, the fragment, the host in both cases) reads as a usable cache and reacheswake_context's source string, the legacy integer stays an integer, and the tunables of a secret-revision cache apply.Tests at this head on python3 3.14 (
