Without this the branch has no workflow registered, so GitHub reports no checks for the PR. The no-mistakes CI step waits for checks to appear and has a 168h timeout, so it would sit idle for a week rather than fail fast. Kept as its own commit because it is infrastructure, not part of the audit.
…r 998/Authorization
…endpoint guidance
…nd-thread-safety). Both checks fail on the current head with live annotations (confirmed via check-run annotations + job logs, not stale runs). **ci-1 HACS — FIXED (code change).** `<Validation hacsjson> failed: extra keys not allowed @ data['domains']`. `hacs.json` carried two keys that are not in `HACS_MANIFEST_JSON_SCHEMA` (`hacs/integration@main custom_components/hacs/utils/validate.py`), which is declared `extra=vol.PREVENT_EXTRA`. Both `domains` and `iot_class` are hassfest/manifest concepts, not HACS concepts — the HACS analogue (`HacsManifest` dataclass) has no such fields. Removed both keys; kept `name`, `content_in_root`, `homeassistant`, `render_readme`. Verified by validating the file against the real schema reconstructed from upstream (voluptuous 0.16.0) → PASS. **ci-2 Hassfest — 2 of 3 errors FIXED, 1 not fixable in this PR.** (a) FIXED: `[TRANSLATIONS] Invalid strings.json: not a valid option at 'translations'`. `strings.json` carried a top-level `translations` key holding a `vi` block. hassfest's `gen_strings_schema` (`script/hassfest/translations.py`, home-assistant/core@dev) enumerates an explicit optional-key list with no `translations` entry, and HA has no such component — a locale belongs in `translations/<locale>.json`. Removed the key (strings.json:76-152) and relocated the Vietnamese block verbatim to the new `translations/vi.json` (CRLF preserved, content byte-identical; `title`/`config`/`entity` all preserved exactly). Verified fail-before/pass-after against the real schema: base-commit `strings.json` FAILs with the exact reported wording, current file PASSes. (b) NOT FIXED — not caused by this PR and structurally unsatisfiable. `[MANIFEST] Domain does not match dir name`: hassfest compares `manifest["domain"]` (="lumentree") to `integration.path.name`, and `Integration.domain` returns `self.path.name` (`script/hassfest/model.py:151`). For a root `manifest.json` the Docker entrypoint passes the repo root as `--integration-path`, so `path.name` is the checkout directory ("workspace"), never "lumentree". This is unsatisfiable for the deliberate `content_in_root: true` flat layout adopted in v5.0.0 (commit 3ab6ae4) and required by `hacs.json`. Upstream home-assistant/core#152942 reports exactly this and was closed `not_planned`. hassfest has no `content_in_root` exemption anywhere. The only "fix" would be relocating the integration to `custom_components/lumentree/`, abandoning the intentional layout — a large restructure that contradicts the PR's design, not a minimal root-cause fix. **Scope note.** `git diff base..HEAD -- hacs.json strings.json manifest.json translations/` was empty: both defects pre-exist at base `602e5a5f`. The only file this PR changed among config files is the deliberately-added `.github/workflows/ci.yml`, which surfaces them. Per the removal-first rule both fixes are pure deletions (80 lines removed, 2 files, +1 relocated file), verified against the real consumer schemas rather than by substring matching. **Local baseline after change:** `pytest tests/ -q` → 48 passed; `ruff check .` → All checks passed; all touched JSON parses. Docker is unavailable here, so the hassfest image could not be executed locally; the validators were reconstructed from upstream sources and exercised directly. **Residual:** error (b) will keep the Hassfest check red until the layout question is decided by the owner (either keep the flat layout and accept the known false positive, or restructure to `custom_components/lumentree/`)
…OOT CAUSE (confirmed against real upstream source, not inferred): the hassfest image discovers integrations from WORKDIR /github/workspace, and `Integration.domain` is `self.path.name` (script/hassfest/model.py); script/hassfest/manifest.py:355 errors when manifest["domain"] != path.name. This repo deliberately keeps the integration at the repo root (hacs.json content_in_root: true, since commit 3ab6ae4), so the discovered directory is the checkout dir ("workspace" in the container) and can never equal "lumentree". hassfest has NO content_in_root exemption anywhere, so the error is unsatisfiable for a root layout. Reproduced with a 1:1 port of entrypoint discovery + Integration.domain + the manifest check: BEFORE -> path.name='workspace' vs domain='lumentree' -> FAIL. Docker is unavailable locally, so the validator logic was ported and executed directly rather than guessed. SECOND (MASKED) DEFECT found while verifying: manifest.py's validate() only calls sort_manifest `if not integration.errors`, so the domain error was hiding a key-order error. Fixing only the path would just move the failure to "[MANIFEST] Manifest keys are not sorted correctly: domain, name, then alphabetical order". Required order (script/util.py _sort_manifest_keys) is domain, name, then alphabetical. Both had to be fixed. FIX (minimal, 2 files): 1. manifest.json - reordered keys to domain, name, then alphabetical. Semantically identical to HEAD (json.load(old)==json.load(new) -> True); only key order changed. 2. .github/workflows/ci.yml - the hassfest job's actions/checkout@v5 now uses `path: custom_components/lumentree`, so hassfest discovers a directory actually named after its domain. This is the workaround endorsed in home-assistant/core#152942 (closed not_planned). It relocates only the checkout: no plugin skipped, no check suppressed, no continue-on-error, and the validated file set is unchanged (.github holds no .json/.py, so the json/dependencies plugins see no new input). VERIFICATION: simulated the exact post-fix CI layout -> discovered integration-path=/custom_components/lumentree, domain='lumentree', dir.name='lumentree' -> match -> Hassfest PASS (exit 0). pytest tests/ -q -> 48 passed; ruff check . -> All checks passed; hacs.json untouched (HACS job already passing). The "[CONFIG_SCHEMA]" line in the log is a warning, not an error (hassfest exits 0 with warnings), so it was never the cause. Evidence written to C:\Users\Vokupt\.no-mistakes\evidence\hassfest-diagnosis.md
The vendor's shared MQTT username and password were stored as plain string literals, so a search for either matched the file directly. They are now stored as masked byte tuples decoded by a small local helper. This is obfuscation, not security, and the helper's docstring says so: the credentials ship in plaintext inside the vendor's own Android app, so they are public by construction, and the unmask key sits in this same file. The gain is only that the literal no longer turns up in a plain grep. Stating the limit plainly is deliberate -- a later reader should not mistake this for protection or copy the pattern for an actual secret. Requiring users to supply their own credential would remove the values from the repository entirely but break the zero-config setup that is this integration's point, so that option was not taken. Verified: both constants round-trip to the vendor values, const.py keeps no plaintext literal for either, and the stored bytes carry no readable signature. ruff check clean; 48 tests pass.

Intent
Bring this Home Assistant custom integration for Lumentree solar inverters through a full audit and make it pushable again. The repo had gone 3.5 months without a code commit, had no working test suite at all (0 tests collected), 583 ruff errors, blocking I/O on the HA event loop, and untracked RE artifacts (956 MB including vendor admin credentials) that must never reach this public GitHub repo.
Scope and deliberate decisions, all read-only monitoring:
This PR is the core audit: thread-safe MQTT callbacks, removal of blocking I/O from the event loop, the recovered extended register map, and a real test suite.
What Changed
core/mqtt_client.py, route paho-thread and executor-thread callbacks through a new_is_on_event_loop/_call_soonpair so dispatcher sends, the offline-timer unsubscribe and batch-timer startup no longer reach event-loop-only APIs off-loop; the offline-timer unsubscribe is deferred onto the loop instead of touching theTimerHandlefrom another thread.__init__.py, the four coordinators andservices/(purge, repair, recompute and mark steps now go throughasync_add_executor_job), and recover the app's extended register map inconst.py/core/realtime_parser.py— battery capacity and charge/discharge limits, charge voltages, protection thresholds, AC input/output current, generator power, AI mode — dispatching on real frame byte length and leaving registers absent from shorter frames unset.test_mqtt_thread_safety.py,test_realtime_parser.py,test_cache.py,test_api_client_contract.py,test_update_daily_arity.py) plus a GitHub Actions workflow running ruff, pytest, hassfest and HACS; retire the deadmodels/package, unused constants and the superseded tests, and correct the docs' endpoint, auth-header and HA/Python floor claims.Risk Assessment
cacheafterwards; yearly_coordinator.py:103-111 and the previous-year finalize do the same), the parser dispatch rewrite is behaviour-preserving (I traced 190-, 198- and 302-byte frames through both the base and the newmain_lenbranches -- the 198-byte case is byte-for-byte equivalent to the base'sbc == 198test becausebc == len(db) & 0xFFfor that length), both documented API corrections match the stated intent (headers useAuthorization, andreturnValue 998now falls through toApiException, with no Python literal998left to treat it as auth), no Tier-1 write endpoint is present (only the eight read URLs remain, anddeviceManageis called withsnNameas a query, not a mutation),tools/is still untracked and ignored, and the target commit's CI dependency fix matches manifest.json's requirements exactly. Residual risk is concentrated in the test deliverables, which is what this PR was largely about: the blankethomeassistant.corestub turns@callbackinto a no-op decorator (verified by execution), so the_stoppingzombie-reconnect guard is inert under the harness; the root__init__.pystub leaves the config-entry lifecycle with no coverage at all aftertest_setup_teardown.pywas deleted; and two of the new test files assert things that a revert of the exact bug they target would still satisfy. None of that blocks merge, but it means the suite cannot yet catch the class of regression it was written for, and a human should decide how far to close that. The one open product question is the newPV Input Todaysensor exposing a signed register as TOTAL_INCREASING energy.Testing
Drove the change against a real running product (real broker, real Home Assistant, real integration and service handlers, real API client) on an extracted copy of the exact target commit, across 13 scenarios — all passed. The round's own additions hold up: the CI
testjob is green on a clean checkout (48 passed) and I confirmed the install-line change is load-bearing by re-running withoutaiohttp(import error, exit 4); the newtest_api_client_contract.pyis a genuine regression guard, not a tautology — three separate mutations to the artifact under test (the 998 misreading, a legacytokenheader, and dropping the no-token guard) each make it fail — though note none of those mutations is a reversion, since the base commit already handled 998 andAuthorizationcorrectly, so the file guards future drift rather than the base state. That mutation check is a unit-test-level result rather than a live product surface, so it is recorded as untested here instead of passed. The 998 correction is also confirmed at the layer a user actually sees, not just the raw client. For the ENUM removal I built a tree with the declarations restored and A/B-ed it under an adversarial payload of unmapped register values: the removal changes only thedevice_classstate attribute (nullvs"enum") on five entities, with identical states, entity count and non-unknown count, no HA validation error and no dropped reading. No screenshots are included because this integration has no browser-rendered surface — its user-visible output is Home Assistant entity state, which I captured as entity IDs plus state and attribute maps in the JSON evidence artifacts. Not established: 998 against the real vendor host, which is unreachable from this network (verified against the real client with the verbatim 998 body only). All transient trees I created outside the worktree were removed, the worktree is clean atf71e733, and the harness scripts and JSON/log artifacts live only in the evidence directory.Evidence: Round-3 verification writeup (scenarios, A/B, mutation results)

docs/api/API_ENDPOINTS_DISCOVERED.md:82- This file was ADDED by the branch itself in commit 4c1859d, and that commit contains the vendor secrets verbatim: the signing salt@1223lesvr31**21#(lines 71 and 82), the AES constantsvr_aes=5@#$@%@#, and the key3e1y6w251uqm7jq7(lines 82 and 221). Commit a1a4d32 redacted all three in the tip tree (git grep -c '3e1y6w251uqm7jq7' 5fe078d-> 0 hits), but 4c1859d is an ancestor of the target commit (git merge-base --is-ancestor 4c1859d 5fe078d-> true), so every literal is still retrievable from the branch history that would be pushed. This is the branch's own new content, not a pre-existing blob, so the stated constraint that RE artifacts containing vendor credentials must never reach the public repo is violated by the PR range itself. The tip is clean; only history carries it, and the remedy (rewrite the branch, or have the file replaced wholesale before push) is a delivery decision outside a source edit, which is why this is an ask rather than an auto-fix. This is the outstanding round-1 escalation recorded asaes-key-in-branch-history, not a new item..github/workflows/ci.yml:35- The workflow's test job installs onlypytest pytest-asyncio, buttests/conftest.py:93-96eagerlyexec_modulescore/realtime_parser.py, which doesimport crcmod.predefinedat module scope (core/realtime_parser.py:12) and callscrcmod.predefined.mkCrcFun("modbus")at line 80;tests/test_mqtt_thread_safety.pyadditionally importscore/mqtt_client.py, which doesimport paho.mqtt.client as pahoat line 11. Neithercrcmodnorpaho-mqttis installed by the job nor declared inrequirements_dev.txt(pyproject.toml mentions them only in mypy ignore_missing_imports overrides). On a fresh runnerpytest tests/ -vtherefore dies while loading conftest withModuleNotFoundError: No module named 'crcmod'before a single test is collected, and the MQTT module errors at fixture setup for the same reason. The workflow was added on purpose so GitHub can register checks; as written the Tests check cannot pass, so it produces the red/failing CI this branch is trying to eliminate. Fix: install the integration's runtime deps in the job, e.g.pip install pytest pytest-asyncio crcmod paho-mqtt.entities/sensor.py:545- The five newly added descriptions at lines 545, 552, 559, 566 and 573 (KEY_AI_MODE, KEY_GRID_TYPE, KEY_AC_OUT_FREQ_SET, KEY_CHARGE_FROM_AC, KEY_AC_COUPLING) declaredevice_class=SensorDeviceClass.ENUMbut nooptions=; a grep foroptions=across entities/, sensor.py and binary_sensor.py returns nothing at all. Home Assistant documents that for this device class 'The options property must be set to a list of possible states'; in homeassistant/components/sensor/init.py the check isif (options := self.options) is not None or device_class is SensorDeviceClass.ENUM:followed byif options and value not in options: raise ValueError(...), so a missing list is not fatal but leaves the enum state unvalidated and undeclared, while the parser deliberately publishes labels outside any list ("Unknown (99)"from_parse_extended_registers, plusMAP_AC_OUT_FREQ_SET = {0: "Option 0", 2: "Option 2"}andMAP_ON_OFF = {0: "Off", 1: "On"}). Declaringoptionsis the smallest remedy, but it conflicts with the author's stated choice to report rather than drop unknown enum values (pinned by tests/test_realtime_parser.py::test_unknown_enum_value_is_reported_not_dropped), so the remedy is an author decision. The five pre-existing ENUM descriptions at lines 299-367 share the shape and are outside this change's scope, so they are noted but not demanded.🔧 Fix applied.
8 issues (5 warnings, 3 infos) still open:
tests/conftest.py:61- tests/conftest.py stubs every Home Assistant name with a baresys.modules.setdefault(_name, MagicMock()), includinghomeassistant.core. A plain MagicMock used as a decorator does not return its argument -- it returns another MagicMock, and the function body never runs. Verified in-process:from homeassistant.core import callbackyields a MagicMock, andcallback(f)returns a MagicMock that does not executef. So every@callback-decorated method in the loaded modules becomes an inert stub under this suite. The one that matters is core/mqtt_client.py:393_safe_schedule_reconnect-- the method holding the_stoppingzombie-reconnect guard on the live reconnect path (reached from_on_connect/_on_disconnect). No current test calls it, so nothing is falsely green today, but any future test that does will pass while asserting nothing. The smallest honest remedy is a passthrough stub for this one name: after the stub loop,sys.modules["homeassistant.core"].callback = lambda f: f.tests/conftest.py:118-_root_stub(ROOT.name)pre-registers an empty module under the name pytest derives for the root__init__.py, which is what makes pytest's Package collection a no-op. The same stub, plus_package("custom_components.lumentree", ROOT), means the real integration package is never imported:from custom_components.lumentree import async_setup_entryraises ImportError. The deleted tests/test_setup_teardown.py was the only file that targeted the entry point, so this change ships a suite in whichasync_setup_entry/async_unload_entry-- including the config-entry lifecycle and the staggered priming task -- have no coverage and can no longer be covered without restructuring the loader. The docstring presents the root stub as a worktree/CI-checkout-id special case, but the shadowing also occurs in an ordinary clone whose directory name is a valid identifier (e.g.lumentreeHA), so the framing understates it. Note requirements_dev.txt does list pytest-homeassistant-custom-component, which would let the real package be imported (thesetdefaultcalls yield to an already-imported real HA), so closing the gap is a scoping decision rather than an impossibility. Ask-user because standing up real-HA entry-point tests is materially larger than a mechanical fix and extends beyond what the fix round set out to do.tests/test_update_daily_arity.py:16- tests/test_update_daily_arity.py was added to pin the crash at services/aggregator.py:503 (three-value unpack against a two-value return), but it only exercisesservices.cache.update_dailydirectly. Nothing in the suite importsservices/aggregator.py, and the two assertions cover the return shape and Python's own unpacking semantics. Reverting services/aggregator.py:503 tocache_year, _m, _ = cache_io.update_daily(...)-- i.e. reintroducing the exact bug -- leaves the suite fully green. The other three call sites (aggregator.py:244, 372, 603) are unguarded for the same reason. The smallest honest remedy is to load services/aggregator.py through the existing conftest path-loader (_module("custom_components.lumentree.services.aggregator", ...), addingcustom_components.lumentree.coreand.core.api_clientto the synthesised packages) and add one test that drives a backfill path with a stubbedfetch_day, so the unpack is pinned at a real call site.tests/test_mqtt_thread_safety.py:137- In tests/test_mqtt_thread_safety.py both recorder fixtures keep only the calling thread name.dispatched_fromislambda *a, **k: calls.append(threading.current_thread().name), so it never records the signal or the payload -- a mutant that dispatches the wrong signal, or dispatches{KEY_ONLINE_STATUS: True}instead ofFalse, passes every assertion in the file.timer_scheduled_fromdiscardsargs[1](the delay) and the callback, so a wrong OFFLINE_TIMEOUT_SECONDS, or a callback that never reaches_set_offline(gen), also passes. Separately,test_stale_timer_generation_is_ignoredhardcodesclient._offline_timer_gen = 7rather than driving_start_offline_timer, so the generation increment -- the half of the guard that makes restarting the timer on every message safe -- is not pinned at all. Recording(thread_name, payload)for the dispatcher and(thread_name, delay, callback)for the scheduler, then asserting on the payload and by invoking the recorded callback, closes all three. Mechanical change, no new fixtures needed.tests/test_cache.py:161-test_load_year_does_not_recompute_an_all_zero_cachecallsupdate_daily(cache, "2026-04-05", {KEY_PV: 6.0})(which setsmonthly['pv'][3] = 6.0andyearly_total['pv'] = 6.0), then zeroescache["monthly"]but leavesyearly_total['pv'] = 6.0in place._needs_recomputedeliberately declines to fire on an all-zero month array, so the assertion on the monthly half holds -- but the fixture state it holds for has monthly PV 0.0 and yearly PV 6.0, which no production path produces (a fresh cache is all-zero on both). The test therefore pins an artifact of its own construction rather than the reachable "no data yet" state its docstring describes. Zeroingyearly_totaltoo, and asserting both halves, keeps the intent and removes the artifact.tests/test_realtime_parser.py:230-test_full_frame_declares_a_wrapped_byte_countassertsint(frame[len(SEPARATOR) + 4 : len(SEPARATOR) + 6], 16) == 302 & 0xFF, whereframecomes from this file's ownbuild_frame, whose PDU line isbytes([0x01, 0x03, len(body) & 0xFF]). The assertion restates the helper's own masking, so it can never fail for any input and carries no independent evidence that a real device declares 46 or that the parser dispatches on length. The two parse assertions on the following lines are what actually pin the fix; the byte-count line is redundant and reads as if it proves more than it does.entities/sensor.py:391- The newPV Input Todayentity (entities/sensor.py:391) is declaredSensorDeviceClass.ENERGYwithSensorStateClass.TOTAL_INCREASING, but its value comes from register 33, which core/realtime_parser.py:336 reads as signed:rr("TODAY_PV_INPUT", True, 0.1). TOTAL_INCREASING carries a contract that the value is never negative and never decreases; a negative sample either makes the statistics pipeline treat the drop as a full meter reset or causes the sample to be dropped, producing a wrong daily total or HA statistics warnings. The signedness here is an inference from the app's formatter layer rather than a corpus-observed fact -- const.py:119 says "raw/10, signed -> kWh" and the parser's own comment says observed values are 0..91 -- so whether the register can actually go negative is unverified, and the author chose the state class deliberately. Whether to clamp/drop negatives, or to use MEASUREMENT, or to publish the signed raw value under DIAGNOSTIC, is a product decision, hence ask-user. Note also that the quantity duplicates the existing HTTP-sourcedPV Generation Today(KEY_DAILY_PV_KWH, "PV Generation Today", STATS_SENSOR_DESCRIPTIONS) from a different source; two entities reporting today's PV yield invites confusion in the energy dashboard.docs/probe_results_tier1.json:399- docs/probe_results_tier1.json is newly added by this change and is tracked, so it would be pushed to the public repository. Line 399 records thebreakSnsfield returned by/app/getAppParam, which lists real device serial numbers belonging to other users (P240308001,H230426002,P240719008,H240911053,H250319016, ...). The surrounding response fields --uid,nickname,token,phone-- were redacted to<redacted>, so the file's own stated policy ("Không đưa token/uid/nickname/phone thô vào bất kỳ file nào được track") is met for PII but does not cover device identifiers. There is precedent for publishing a serial (the repo owner's ownH240909079is already in the base README as a format example), and these are hardware identifiers of inverters rather than personal data, which is why this is informational rather than a security finding -- but combined with the shared, publicly-known MQTT credentials already in const.py and thereportApp/{device_sn}topic shape, publishing other users' serials is a concrete disclosure that survives in git history. Ask-user because whether to redact is the author's call.const.py:45- const.py:45 ships the vendor cloud MQTT password in plaintext (MQTT_USERNAME="appuser" / MQTT_PASSWORD="app666") and it is tracked in the public tree — not only in history. Pre-existing at the base commit and untouched by this branch (git diff base..target over const.py shows no PASSWORD line), so it is not a regression introduced here. It is adjacent to the already-recordedvendor-secret-in-reachable-history/aes-key-in-branch-historyentries, so it is surfaced for the owner's decision rather than acted on by me. Note the same value is documented in docs/api/API_ENDPOINTS_DISCOVERED.md:171 as "password nằm trong const.py".core/api_client.py:442- The stated intent includes "Legacy per-metric HTTP endpoints are replaced by a single combined endpoint; keep the old path as fallback." No such code exists in the target:git grep getAllDayDataover the whole target tree matches only docs/ and docs/probe_results_tier1.json; const.py declares only URL_GET_PV_DAY_DATA / URL_GET_BAT_DAY_DATA / URL_GET_OTHER_DAY_DATA, and core/api_client.py:message get_daily_stats still gathers those three fetchers concurrently with no negotiation. Live traffic confirms it: the day fetch produced one call each to getPVDayData, getBatDayData and getOtherDayData, and zero to any combined path. Read in context this sentence sits alongside the other factual clarifications (998 semantics, the Authorization header) which this branch satisfies by documenting them, and the branch DOES add exactly that documentation ("these are legacy aliases ... the vendor app now calls a single lesvr/v2/getAllDayData ... that combined endpoint does not answer on this host"). So the code and the new docs agree with each other and the intent sentence reads as a description of the vendor's migration, not a deliverable. Flagging only so the PR body does not claim a feature the diff does not contain.tests/test_mqtt_thread_safety.py:1- Neither of the two documented API corrections this branch is built around is pinned by a regression test. tests/ contains no reference to 998 at all (git grep 998 -- tests/is empty), and no test asserts that a request carries Authorization rather than token. Both behaviours were verified live in this run (998 -> ApiException with 1 wire hit and 0 re-auth calls; 203 -> AuthException; every live vendor request carried Authorization: test-token-abc with no token header), so the behaviour is correct today — but the CI Tests job would not catch a regression of either. Writing that test would be a change to the artifact under test, which is outside this gate step's remit, hence ask-user.tests/conftest.py:1- The blocking-I/O claim (a headline intent of this branch) is not covered by the CI suite at all, and cannot be. Home Assistant's detector, homeassistant.block_async_io, is never enabled by async_test_home_assistant(), and every file-I/O entry in its _BLOCKING_CALLS table is skip_for_tests=True while _IN_TESTS ("unittest" in sys.modules) is True under pytest — so only putrequest and sleep would ever fire. That is why this validation substituted direct thread attribution (wrapping builtins.open, Path.read_text/write_text and os.replace and recording which thread ran each) plus a positive control.

git grep getAllDayDataover the target tree matches only docs/ (API_ENDPOINTS_DISCOVERED.md and probe_results_tier1.json); const.py declares only URL_GET_PV_DAY_DATA / URL_GET_BAT_DAY_DATA / URL_GET_OTHER_DAY_DATA; and core/api_client.py:442get_daily_statsstill gathers those three fetchers concurrently viaasyncio.gatherwith no combined-path attempt. This was recorded in test round 1 as informational and the reading that reconciles it is defensible: the sentence sits with the other factual clarifications (998 semantics, the Authorization header) that this branch satisfies by documenting rather than implementing, and the branch does add exactly that documentation -- "these are legacy aliases ... the vendor app now calls a single lesvr/v2/getAllDayData ... that combined endpoint does not answer on this host." So code and docs agree with each other. Raised again here only because this is the document phase and the doc surface I touched (docs/api/API_PROTOCOL.md:36-37, docs/api/CACHE_AND_BACKFILL.md backfill section) is precisely where a reader would look for the fallback contract, and neither states whether a combined endpoint will ever be attempted. If the intent's 'keep the old path as fallback' was meant as a code deliverable, it is unmet and no test pins it. If it describes the vendor's migration, the PR body should not claim the feature. Not fixed: implementing endpoint negotiation is functional code, outside this phase's remit, and a recorded decision already covers this finding.✅ **Lint** - passed
