checks / unit (pull_request) Successful in 6m22s
Review approved and found four things worth fixing. Three are cosmetic; the
fourth is the same defect this card is about, one level up.

⚠️ THE FLOOR WAS PRINTED AS 59 AND ASSERTED AS `> 15`. So a manifest change
dropping the required count to 20 would have passed while the sentence beside it
still said 59 - a number displayed but not graded, which is exactly what let
UX-01's AC 3 survive review in the first place, and exactly the shape
`test_translations.py` was already fixed for.

Now DERIVED and graded in two separate assertions, because they are two
different claims:

  1. `_EXPECT_REQ = len(schema) - len(_OPTIONAL)`, where optional is Supervisor's
     own rule - a `?` suffix, plus `inverters` because `UiOptions` marks a list
     optional - asserted EQUAL to Supervisor's required count. The printed
     number is computed, so it cannot go stale.
  2. ⚠️ AND THE WITHDRAWAL'S PREMISE, SEPARATELY. The equality alone is not
     enough and I checked why: both sides read the same `?` convention, so
     marking a key optional moves BOTH and it stays green - measured, by making
     `slew_w` optional and watching it pass. That grades Supervisor agreeing
     with us, NOT the thing AC 3 was withdrawn for. The second assertion grades
     the premise: the floor is still far above the ~15 AC 3 asked for, and if it
     ever is not, the withdrawal needs re-arguing rather than re-asserting.

Driven, both directions, against the real 2026.08.0 image:

    clean                         PASS  "floor is DERIVED: 71 schema keys minus
                                         12 optional ones is 59, and
                                         Supervisor's own required flag agrees"
    premise threshold 15 -> 40    FAIL  "the floor of 59 is still far above
                                         the ~40 AC 3 asked for"

Also: a dangling reference to `DECISIONS/UX-04-hiding-and-the-deepmerge.md`,
which was never the filename shipped, and `DOCS.md` still saying section F
"prints" what it now grades.

Not changed, and review agreed both are disclosed rather than defects: the
pair-keyed ledger cannot see a SECOND site for a pair it already holds (the
site count can grow while the pair set cannot), and the probe's assertions run
by hand rather than in CI because they need the Supervisor image - the same
status as before this card, not a regression.

Suite: 27 files, all pass. Probe: all cases passed on
ghcr.io/home-assistant/amd64-hassio-supervisor:2026.08.0, --network none.

Claude Opus 5 21f22b393a UX-04: nothing was hidden, the defaults pin was never built, and CFG-04 was closed by UX-02
checks / unit (pull_request) Successful in 6m20s
UX-01's three unmet acceptance criteria, closed out. It shipped in 0.7.0 and is
LIVE, so all three describe the running install. No behaviour, no schema and no
default moves here: config.yaml, translations/ and every module under app/ are
byte-identical to 6e7b233.

⚠️ AC 3 - "the visible count drops to ~15" - IS WITHDRAWN AS UNSATISFIABLE, and
the arithmetic is the reason rather than the effort. options: and schema: both
declare all 71 keys, so the set HA's toggle can hide is EMPTY - it hides a key
only when it is ?-optional AND absent from options:, and nothing is absent. But
the deeper fact is that no manifest could have met it: Supervisor's own
UiOptions marks 59 of the 71 REQUIRED, and the frontend's own filter -
`schema.filter(e => e.name in opts || e.required)`, transcribed out of the
bundle in the release image - shows a required field unconditionally. So 59 is
the floor with options: EMPTIED ALTOGETHER. The target was ~4x below anything
reachable.

⚠️ AND THE 12 HIDES THAT ARE EXPRESSIBLE WOULD BE BOUGHT WITH THE UPGRADE PATH.
A key absent from options: has no default for the Supervisor to deep-merge into
an existing box's stored blob. That is exactly the delivery_hold_s mechanism
this release rests on: a REQUIRED key a 0.7.0 blob has never stored resolves to
its options: default of 185 instead of becoming exit 78. Hiding a key is
precisely the edit that removes that. It would also promote the 27 unpinned
in-code literal fallbacks the new check ledgers into the ACTUAL source of the
defaults on a live install - the CFG-03 defect the same card's AC 4 exists to
police, made load-bearing by its AC 3.

⚠️ THE COUNT WAS PRINTED AND NEVER GRADED, WHICH IS HOW THIS PASSED REVIEW.
supervisor_shape_probe.py section F has printed "the Configuration tab renders
71 fields" since the day it was written and exited 0 through UX-01's whole
review while displaying the number that contradicted the criterion it was
evidence for. Three assertions replace the bare print, every number computed
from the manifest and from Supervisor's own `required` flag rather than typed,
including an ISOLATED COUNTERFACTUAL that empties options: and nothing else.
MEASURED RED: delete one key (price_feed_url) from options: and two of them
fail - `Hideable: ['price_feed_url']`, `70 of 71 fields render` - exit 1.

--- AC 4: the AST check, built --------------------------------------------

AC 4's first clause is VACUOUS over an empty set (see above) and its second -
"the table changed goes red" - already works six times over. The third, the one
with the content, was never written: the only literal scan in the repository is
test_validate.py's regex over eight maintenance_* keys, which is a grep and
predates the card.

test_defaults_pin.py walks ast.Call nodes over app/*.py. It:

  - DISCOVERS the six *_OPTION_DEFAULTS mirrors from the tree rather than
    naming them. Every existing pin names its own table by hand, so a SEVENTH
    table added tomorrow is pinned by nobody and nothing says so;
  - grades all 30 mirrored keys against config.yaml, and requires that no
    module carries a literal fallback for any of them;
  - FREEZES the CFG-03 backlog at exactly today's 27 (module, key) pairs, by
    pair and not by count - a count goes green again the moment one site is
    deleted and another added. Line numbers are deliberately out of the key: a
    ledger that reddens on an unrelated reformat is one people re-bless without
    reading. It can only shrink;
  - grades every remaining literal AGAINST config.yaml, which is the half that
    catches CFG-04's actual failure - two copies of one number, one moves.

⭐ ONE PREVIOUSLY UNREPORTED DIVERGENCE, and it is what that last check is for:
main.py:290 answers a missing target_grid_w with 0 where config.yaml ships -10.
It cannot reach an operator - the deep-merge guarantees the key is present - and
the only paths that hand over a partial dict are sim/inject.py and this repo's
fixtures. Recorded as the single permitted divergence with its reason rather
than corrected; changing it alters the control loop's target and belongs to a
card that grades the loop. A second divergence goes red.

⭐ THE RED DIRECTION WAS RUN, TWICE OVER. Part 5 feeds the scanner a synthetic
module containing a deliberate violation of each rule and REQUIRES it to be
caught, in-process, through the same function the graded parts call - so a
scanner that goes blind stops working there too - and the site total is graded
against a floor. And a literal was planted in the REAL tree:

    main.py:290  float(opts.get("maintenance_charge_w", 2000))
    -> FAIL no literal fallback survives for any of the 30 keys a mirror
       already answers for                                          exit 1

    main.py:290  opts.get("p1_host", "x"), opts.get("slew_w", 999)
    -> FAIL no NEW module/key pair has started carrying a literal fallback
            [('main.py', 'p1_host')]
       FAIL every remaining literal still AGREES with config.yaml
            main.py  slew_w: code 999 vs config.yaml 0               exit 1

Both plants removed.

--- AC 5: CFG-04 is closed, and not by this card's predecessor -------------

fef6ef2 touched config.yaml, translations/, test_translations.py and the probe -
no defaults code at all - and on 0.7.0 the max_w 2000 -> 2500 triple mutation
survives 21 files, 0 RED. CONFIRMED CLOSED on release/1.0 by re-running the same
triple mutation on a throwaway copy of 6e7b233: 26 files, RED at
test_selfconfig.py, exit 1 -

  1 FAILED: ⚠️ CLEARING max_w ON THE LIVE SHAPE IS REFUSED - rule 10 catches
  the rail collapsing to the 2000 default under an explicit 400 W slew

git log -L 310,325:test_selfconfig.py attributes that check to bcee235,
"UX-02: pin both halves of the max_w fix, because neither was graded". The AC is
met BY UX-02 and ships with the pending 0.9.0 deploy. Nothing was re-done.

--- the 8 per-entry translations: they stay --------------------------------

Measured negative and not a defect in them: UiOptions gives inverters type
schema WITH multiple, the frontend sends that case to ha-selector-object, which
labels fields `fields[name].label || name`, and the converter sets neither label
nor translation_key. The Supervisor tab CANNOT be made to render them. They stay
because UX-02's ingress panel is the surface that can, because they cost
nothing, and because deleting them removes the only thing that would catch a
per-entry key added without a translation - which is how SAFETY-32's REQUIRED
bms_soc_floor would have joined the roster unlabelled. A written decision, not a
change; translations/ is untouched.

tools/supervisor_selfapi_probe.py stays red on its hardcoded len(_sub) == 7.
That is TOOL-04, already filed, and it is not re-filed or fixed here.

--- evidence ---------------------------------------------------------------

  positive control  test_defaults_pin.py's mirror floor moved 6 -> 7 inside the

Nothing here touched hardware, the live Home Assistant at 192.168.2.158, or
sim/. Both probe runs were throwaway containers over a read-only mount.

DECISIONS/UX-04-the-configuration-tab-and-the-defaults-pin.md carries all four
decisions, the frontend transcription, and the two counterfactual transcripts.

glenn schrooyenandClaude Opus 5 1ba35f9c99 PKG-13: one safe.directory flag, not two, and the tighter of the pair
checks / unit (pull_request) Successful in 6m19s
Review found `-c safe.directory={where}` and `-c safe.directory=*` set on the
same invocation, the specific value redundant once the wildcard is present.

Dropped the WILDCARD rather than the specific path, which is the opposite of
the suggestion and the tighter end of it: `_git()` always runs `-C where`, so
the only repository it ever reads is the one it was pointed at, and naming that
one path grants exactly the trust the tool needs. `*` granted trust to every
repository on the machine for the lifetime of each subprocess - harmless for
read-only `log`/`show` with no tty, as review measured, but broader than the
job.

Verified after the change: the documented container invocation still runs BOTH
halves and reports `no runtime change since the last bump` / `CLEARED for
deploy`, so the fix this branch exists for is intact.

Suite: 26 files, all pass.

glenn schrooyenandClaude Opus 5 0b653c35a6 PKG-13: the no-op half of the pre-deploy check has never run as documented
checks / unit (pull_request) Successful in 6m19s
⚠️ THE INVOCATION ON PKG-09's CARD AND IN THE TOOL'S OWN DOCSTRING RUNS ONLY
HALF THE CHECK. The container runs as uid 0 against a checkout owned by the
operator, and git refuses that:

    fatal: detected dubious ownership in repository at '/w/goodwe-addon'

`_git` returned non-zero, `last_version_change()` returned None, and the
silent-no-op check - THE REASON PKG-09 EXISTS - reported SKIPPED. Measured, on
the documented command against release/1.0:

    ⚠️  SKIPPED: could not ask git what changed since the last bump;
                 the no-op check is INCONCLUSIVE, not clean
    NOT CLEARED

and with `--user $(id -u):$(id -g)`, unchanged otherwise:

    no runtime change since the last bump - nothing to deploy
    CLEARED for deploy.

⚠️ THE TWO HALVES WERE MUTUALLY EXCLUSIVE ACROSS THE TWO DOCUMENTED
ENVIRONMENTS. In the container the validator ran and git skipped; on a bare host
git ran and the validator skipped on aiohttp. NEITHER DOCUMENTED COMMAND RAN
BOTH. The pre-0.9.0 clearance was sound only because it happened to be driven as
two separate invocations.

⚠️ AND IT WAS INVISIBLE IN THE ONLY CASE ANYONE HAD RUN. `main()` consults the
git result only when `shipped == deployed`; every real run so far compared 0.7.0
against 0.9.0 and printed its verdict without ever needing git.

FIXED IN `_git()` WITH `safe.directory`, NOT BY DOCUMENTING `--user`. The tool
should be correct however it is invoked rather than requiring every future
caller to remember a flag; the read is read-only, on a repository the operator
is about to deploy from.

⚠️ WHY THE TESTS COULD NOT SEE IT, WHICH IS THE FINDING BEHIND THE FINDING.
`test_version_gate.py` invokes the gate with `sys.executable` against fixtures
it creates as its own uid, so no fixture could ever meet an ownership mismatch.
MUTATION.md habit 4 in a fourth shape, inside the file written to prevent it -
after the pickaxe bug, after the one-bump history, after the filter-only
survivor. Two fixtures added:

  - a directory that is NOT a git repository, so the lookup genuinely fails:
    the gate must exit 2 saying INCONCLUSIVE and must NOT say CLEARED.
  - ⚠️ THE EXIT CODES PINNED BY VALUE, NOT BY TRUTHINESS. `returncode != 0` is
    satisfied by collapsing NOT-CLEARED into REFUSED, which review found the
    earlier draft could not tell apart. 1 says "this deploy is wrong"; 2 says
    "nobody checked". Driven: collapsing 2 into 1 now goes red on exactly that
    check.

Suite: 26 files, all pass.

glenn schrooyenandClaude Opus 5 04b3330def PKG-09: refuse a deploy that would be a no-op, or that the add-on would reject
checks / unit (pull_request) Successful in 6m16s
Two ways a deploy of this add-on has gone wrong, and the Supervisor reports
both as success.

THE SILENT NO-OP. The Supervisor keys the built image by `version:`, so
`ha apps update` against an unchanged version installs nothing and says it
worked. PKG-06 recorded this on 2026-09-05 with six merges behind an unbumped
version; PKG-07 recorded it again on 2026-09-06 with six. Both times a human
noticed. Nothing else was going to.

THE REFUSED CONFIG. A config the shipped validator rejects is SystemExit(78) -
the add-on does not start. ⚠️ AND THE INGRESS PANEL GOES WITH IT, because the
add-on serving it is not running, so recovery means the Supervisor UI.

⚠️ IT CAUGHT A LIVE ONE ON ITS OWN PULL REQUEST. Run against release/1.0 while
this branch was in review: version 0.8.0 on both sides with UX-02's and
OPT-09's runtime commits already merged behind it. The class this exists to
catch had recurred, the same day, unnoticed - which is the argument for PKG-10,
a non-required post-merge check, since this script only helps someone who
remembers to run it.

⚠️ THE FIRST VERSION WAS BROKEN ON EVERY REAL REPOSITORY AND ITS TESTS COULD NOT
SEE IT. The "when did the version last change" lookup was `git log -S`, the
pickaxe, which finds commits that change the COUNT of a literal string. A bump
edits the line IN PLACE, so the count never moves and it returned only the
commit that first INTRODUCED the line. Measured here:

    -S  ->  0a1e61d  2026-08-23  Packaged as a Home Assistant add-on
    -G  ->  06661c5  2026-09-06  PKG-07: bump 0.7.0 -> 0.8.0

so a correctly bumped tree was reported as 87 COMMITS BEHIND AN UNBUMPED
VERSION, PKG-06's and PKG-07's own bump commits among the offenders. A tool
whose whole purpose is to be trusted cried wolf on every run.

⚠️ AND `-G` IS NOT THE FIX EITHER, ONLY A BETTER FILTER - it matches a reformat,
a quote change, a comment moved onto the line. `-G` narrows the candidates and
the VALUE is then compared against the parent's.

⚠️ THREE DISTINCT SHAPES OF HABIT 4 IN ONE FILE, each found by a different
means, which is the honest record of how this landed:
  1. Fixtures built fresh repositories whose version line is introduced once and
     never edited - the one shape in which `-S` looks correct. Found by review.
     Answered with a three-state history; the old lookup goes red on 4 checks.
  2. That three-state history still could not tell "value-compared" from
     "filtered-only": review swapped in `-G`'s newest raw hit and THE WHOLE
     SUITE STAYED GREEN, so the docstring's central claim was pinned by nothing.
     Answered with a cosmetic touch of the version line - `-G` matches it, the
     value comparison does not. That mutant now goes red on 3 checks.
  3. The counts below were claimed fixed and two of them had not landed at all.

Two git shapes it still gets wrong are recorded in the docstring rather than
fixed - a bump resolved inside a merge commit (false refusal) and a bump
reverted while the work is kept (false clearance, the dangerous direction).
Neither has ever occurred here; both were constructed in review. Card PKG-11.

⚠️ AND THE PROSE COUNTS, WHICH I REPORTED AS FIXED WHEN THEY WERE NOT. Round 1
found "PKG-06 ... four merges" (its own commit message says six) and "recorded
eleven times" (MUTATION.md:550 says TWELFTH). I replaced them without asserting
the replacement matched, said "all applied", and round 2 found both still in the
tree - one fixed in DOCS.md but not in the script, one not fixed anywhere. A
claim that a correction landed is itself a claim that needs checking, and this
is PROC-01's tenth instance.

WHAT IT DOES NOT DO. It does not read the live box: the options blob needs the
Supervisor API. Without --options the validator half SKIPS - loudly, exit 2 -
and never pretends. On a bare host `app/validate.py` needs aiohttp, so that half
skips too and names the container to re-run in. A missing or malformed --options
file is a REFUSAL with a sentence, not a traceback.

EXIT CODES: 0 cleared, 1 REFUSED, 2 NOT CLEARED. ⚠️ 2 IS NOT A PASS.

Suite: 26 files, all pass.

glenn schrooyenandClaude Opus 5 fdaf3fb54f UX-02: the validator's refusals, next to the field, before the save
checks / unit (pull_request) Successful in 6m17s
The Configuration tab can only render types and ranges. `validate.py`'s most
useful refusals are CROSS-FIELD - two inverters naming one `setpoint_entity`, a
`maintenance_charge_w` above `max_w`, a flat `setpoint_entity` left set beside a
declared roster - and the Supervisor's UI has no way to express a rule spanning
two keys. Today the operator meets those as exit 78 in a log, after saving and
restarting. This puts them on the screen beside the field they name, before
anything is written.

WHAT IT ADDS
  app/configui.py     the field model, built from `GET /addons/self/info`'s own
                      `schema` + `translations`. No option key, no label, no
                      rule of its own. UX-01's `Group · ` label prefix becomes a
                      real section heading, in whichever language resolved.
  app/selfconfig.py   the Supervisor conversation and the write gate.
  app/config_page.py  the page. Its longest function decides which HTML input a
                      type deserves; it contains no rule.
  app/web.py          five routes. Still the only file a reviewer has to read to
                      answer "does anything here reach the inverter".

THE FOUR THINGS THAT COULD HURT SOMEBODY, AND HOW EACH IS HELD
  1. A blob the SHIPPED validator refuses is never written - not warned about,
     not written. An invalid blob plus a restart is exit 78, and the panel is
     gone with the add-on that serves it.
  2. A blob that moved underneath is refused, not clobbered. Read hands out a
     sha256 of the canonical blob, save hands it back, and the stored blob is
     re-read IMMEDIATELY BEFORE the write. This is SAFETY-28's discipline
     applied to configuration - "a blob reaches the Supervisor only if it was
     derived from the blob stored right now" - with the honest weakening stated
     in the decision record: a second writer is DETECTED, not made
     inexpressible.
  3. Every message is the validator's own, byte for byte. test_selfconfig.py
     part 6 inserts ONE new rule into a COPY of validate.py, hashes every file
     under app/ to show validate.py is the only one that differs, and serves the
     real /config/validate route out of that copy in a subprocess. The new
     sentence arrives, filed under the key it names.
  4. Nothing on the surface commands an inverter or clears a latch. Saving does
     not restart: applying costs a control interruption - the wind-down commands
     0 W on every inverter - so that is a separate, confirmed button that says
     so first.

MEASURED, NOT CITED (tools/supervisor_selfapi_probe.py, run against
Supervisor 2026.08.0's own code; it contacts nothing)
  - the three self-paths are permitted, and `/addons/self/info` is admitted by
    the `default` role too while `options` and `restart` rest on the bypass
    ALONE. The probe's first draft claimed the role admitted none of the three
    and went red.
  - `/addons/self/options/validate` is NOT reachable from inside an add-on, so
    the only validator this panel can call is ours - which is the one with the
    cross-field rules.
  - a POST that omits a key does not preserve it: the key reverts to
    config.yaml's default. Hence whole-blob read-modify-write.
  - the Configuration tab CAN be removed, and doing so drops 0-of-71 options
    through and takes the add-on down. The card said it could not be; it stays
    by decision, which is a better reason.

DOES NOT TOUCH config.yaml, main.py or any control path. UX-01 is a dependency,
not something this supersedes: its translations are where every label,
description and section heading on this page comes from, and the Configuration
tab is still the recovery surface. DECISIONS/UX-02-two-config-surfaces.md
records which surface is authoritative (neither: the stored blob is) and what
the second surface costs.

Also corrects a stale "70 options" in three prose spots to the 71 the probe
counts - config.yaml grew a key in SAFETY-42 and the sentences did not follow.

---

⚠️ REBASED ONTO release/1.0 @ 3368231, AND HISTORY DELIBERATELY FLATTENED.
The original branch carried `653874d` - an ORPHANED first attempt at PKG-07
whose commit message justified the version bump with a claim that was FALSE
(that `slew_w: 0` used to mean "no limit"; the schema was `int(50,5000)` from
the repo's first commit, so 0 was never legal). That commit's CONTENT was
superseded when release/1.0 was merged in, and the merge resolved correctly -
one 0.8.0 section, no fabricated text. But the retracted claim would have
entered release/1.0's history as a commit message with no retraction attached
to it, where PKG-07's own merged commit is the thing that retracts it.

So the branch is replayed as a single commit on top of the corrected PKG-07
rather than merged with the bad one trailing behind. The tree is byte-identical
to the reviewed branch tip; only the ancestry changed.

adminandClaude Opus 5 5d7e275df4 SAFETY-39: slew_w is a ratio to the rail, and gain is what is still wrong
checks / unit (pull_request) Successful in 5m16s
`slew_w: 1000` was derived on 2026-08-22 against a clamp of 1500 W, where
"capping how far the loop can jump ahead of the inverter" was true because the
rail itself bounded the excursion. The live install went to max_w 5000 and the
constant did not move, so the loop crosses its whole output range in 10 s
against a plant NOTES.md §5.10 measured at ~18 s. Measured on the owner's system
2026-09-05 11:43-11:46: a 3.4 kW export drove the setpoint 380 -> 5000 W in five
2 s ticks, the battery to -5154 W past a 5000 VA rating, and the grid from
3.4 kW of EXPORT to 2.8 kW of IMPORT. Nothing was broken; the rail moved.

REPRODUCED FIRST, and one half of it is not reproducible at all. On
plantsim.Plant and on an independent in-repo model: the setpoint stepping a full
1000 W per tick to the rail (48 of 51 export steps), and the meter crossing from
export into import. The -5154 W figure is NOT reproducible in either model,
because both clamp the plant at its rating - so the card's AC "battery no longer
exceeds max_w in simulation" is unfalsifiable and was rewritten rather than met.

THE DELIVERABLE IS THE RELATIONSHIP.
  SLEW_RAIL_FRAC = LOOP_TICK_S / PLANT_SETTLE_S = 2 s / 18 s = 1/9
  slew_w = 0 now means FOLLOW THE RAIL - SLEW_RAIL_FRAC * max_w - exactly as
  integrator_max_w = 0 already means follow max_w. It is the shipped default:
  222 W at max_w 2000, 556 W at 5000, 1067 W at a ~9600 W two-inverter site.
  validate.py rule 10 refuses an explicit value faster than that, graded against
  sum(unit_caps(opts)) - the roster sum, i.e. Controller.site_max_w - so a
  second inverter moves the bound with no operator action.

VERIFIED BY BREAKING IT: restoring slew_w 1000 at max_w 5000 is refused, and the
refusal names the rail, the crossing time, the measurement and what to do.
Equality, one watt of slack, the live interim 400 and slew_w 0 at every rating
all still start.

GAIN IS THE CONSTANT THAT IS STILL WRONG, and it is NOT changed here. Over 51
export steps the over-absorption is FLAT in slew (958 W at 1000, 1081 W at 250)
and monotone in gain (987 W at 0.6, 876 at 0.3, 435 at 0.2): slew_w bounds the
OUTPUT, while the integrator moves gain*error per cycle and reaches a 5000 W
rail in under three ticks whatever the slew is. Two control-law constants moving
in one release on a running house makes the next measurement uninterpretable.

⚠️ N=2: the site rail becomes sum(max_w) ~ 9600 W (inverter B FROM DATASHEET AND
SERIAL, not measured, and sim/plantsim.py's INVERTER_B is A copied), and the
enforced ratio produces 1067 W there automatically. But a growing rail LOOSENS
this bound, and the >= 900 W symptom goes stale at N=2 the same way the constant
did - both stated in the record rather than left to be discovered.

Nothing reached the inverter. The live install still runs the interim slew_w 400
applied by hand on 2026-09-05, which rule 10 accepts unchanged.

Claude Opus 5 e2efc765af SAFETY-38 round 4: the enumeration covered one sink, and it was not the one this codebase uses
checks / unit (pull_request) Successful in 5m12s
The scanner's two censuses between them scored ONE syntactic sink and called it
the family. Every one of census B's 16 members was a sentence that is APPENDED,
ASSIGNED to a `reason`-shaped name, or passed as a LOG ARGUMENT. Not one was
RETURNED - and census A's return bucket only ever held a callee formatting its
own PARAMETERS, so a method formatting its own ATTRIBUTES and handing the string
back was invisible to both. That is the whole describe() / explain() /
reason-builder family, which is where this repository actually keeps its
operator sentences. Worse than the gap: it was in NONE of the five blind spots
the tool printed about itself.

THE SCANNER, WIDENED - and it rediscovered both members without being told:

  * CENSUS C, the return sink, resolved through the returning method's CALL
    SITES so a returned KEY (store.unit_key, mqtt.unit_state_key - MAINT-05's
    card) is not mistaken for a returned SENTENCE. 53 returned pairs, 39
    reaching an operator, 16 of those sharing a format spec.
  * A sentence handed to a constructor as `reason=` or placed under a "text"
    dict key is a MESSAGE. That one line of the sink walker was hiding SIX more
    caller-built members, census B 16 -> 22.
  * Every census B and C row now prints whether the two interpolations share a
    FORMAT SPEC - the difference between a transposition that is silent and one
    that merely looks broken.
  * The blind-spot list is now TWO lists: what it scans (printed from the
    constants, so they cannot drift) and WHAT IT DOES NOT SCAN AT ALL, largest
    hole first - `%s`-style lazy logging, MEASURED at 31 calls across 8 modules
    and each one listed, not asserted.

CLOSED, both zero-byte survivors of a green 21-file suite:

  * clamp.py:253 ClampResult.describe(), requested_w <-> applied_w. No
    test_*.py mentioned describe() at all. It is the SS15 action-log row
    (main.py:1366) AND the ClampWatchdog notification reason (main.py:2452) -
    the alarm SAFETY-40 and SAFETY-41 are about. Under the swap the guard
    reports a setpoint clamped UPWARD, to +9999 W by a bound whose rating the
    same sentence gives as 2000 W. Pinned on the ORDERED PAIR on the contiguous
    literal at BOTH consumers, operands read off ctl.target and
    hass.writes[-1] - what the loop asked and what the device was sent - not
    off the ClampResult the swap lives in. 4 checks red.
  * peakguard.py:493 PeakDecision.explain(), projected_w <-> ceiling_w. "peak
    guard idle" was in no test_*.py. The row then reads "projects 5013 W under
    a 2300 W ceiling" - 2713 W OVER - on a row whose own words say idle and
    whose own flag says ok. Pinned on the decision and on the shipped status
    row. 3 checks red.
  * test_arbiter.py's scope-violation check, whose CLAIM was wider than its
    ASSERTION. Measured this round rather than left at source level: 0 bytes,
    21/21 green before, red now. 2 checks.

DISCLOSED, NOT CLOSED - 11 measured zero-byte survivors, each with its file
fingerprint and its 21/21 verdict, in the decision doc SS7e-SS7g. Three in
allocator.py's UnitPlan.explain(), three across arbiter.py's two explain()s,
two in tariff.py, two in arbitrage.py's trade reasons, one in main.py's
SoC-floor notification. An enumerated list with honest gaps beats a fifth round
finding a fifth instance.

CORRECTIONS THIS ROUND OWES:

  * The idle sentence does NOT reach main.py:3299/3302 - those are the
    floor-limited branch, where explain() returns self.reason before the idle
    literal is built. It reaches main.py:3313 and, on the release edge, 1951.
    1951 is disclosed unpinned.
  * SS4's "Every one of the ten is red" sat under a twelve-row table: it is the
    ten site_standing entries.
  * SS6b said "weaker evidence than A1-A3"; A4 was measured, so SS7d's
    "A1-A4 and B1" is the right list and SS6b now says it.
  * AND THE PROBE THAT GRADES THESE MUTATIONS WAS THE DEFECT, ONCE. Its first
    cut numbered the operands BY ORDER OF APPEARANCE, so after a transposition
    the other leaf took the same number and all thirteen mutant renders came
    back byte-identical - which reads exactly like "the edit is inert". Keying
    the value to the NAME fixed it. Habit 4, in the measuring instrument:
    MUTATION.md habit 16 is the new entry, and the count there is corrected to
    eleven rather than inflated.

14 mutations measured: fresh full-repo copy each, mounted :ro, bytecode purged
and the purge COUNT printed, the edit re-read from disk, length and sha256
printed on both sides, and every one required to change the EMITTED SENTENCE
and not merely the bytes. 12 survived the pre-round suite, 1 was already
caught, 3 are caught now. Full 21-file suite green on the final tree.

NOT ONE BYTE OF app/ MOVES. This card changes coverage only.

adminandClaude Opus 5 357cb4f07f SAFETY-38 round 3: pin the banner the SHIPPED install actually prints
checks / unit (pull_request) Successful in 5m12s
Round 2 pinned the operand order of `SignWatchdog.evaluate()` at main.py:1620 -
the SITE detector. Part 9c asserts that detector is never armed at a roster of
one, so on every install this add-on has, the PER-UNIT banner is the only
sign-disagreement sentence that can ever be printed, and its call site is a
different line. main.py:1560 was left unpinned.

1. THE SAME ZERO-BYTE DEFECT ONE CALL SITE OVER.
   `evaluate(stood, against, ...)` -> `evaluate(against, stood, ...)`:
   app/main.py 234 542 bytes before and after, delta 0, fingerprint
   61aa413f... -> e57e6026..., bytecode purged, tree mounted :ro, line re-read
   from disk. On the round-2 tree the FULL 21-FILE SUITE PASSES.

   Nothing behavioural could ever have caught it. `watchdog.disagrees()` is
   SYMMETRIC in its first two arguments - `commanded_w * against_w < 0` with an
   abs() gate on both - so the mutant takes identical actions on every input.
   Not "no fixture happens to separate them": no fixture CAN.

   What moves is the sentence. Measured by diffing the suite's own printed
   banners between the round-3 tree and the same tree carrying only this edit:
   9 emitted banner lines invert, in 3 distinct sentences.

     shipped  commanded -2000 W against a meter reading +2000 W
     swapped  commanded +2000 W against a meter reading -2000 W
     shipped  commanded +1000 W against its own measured power -1000 W
     swapped  commanded -1000 W against its own measured power +1000 W
     shipped  commanded -2000 W against a meter reading +4000 W   (the N=1 arm)
     swapped  commanded +4000 W against a meter reading -2000 W

   Persisted to `sign_reason` and re-read after the restart the latch exists to
   survive; also the action log, `_LOG.error` and `status_payload()`'s headline.

   CLOSED by the ORDERED PAIR on both per-unit banners, both operands read off
   the OBSERVED CYCLE - `inv.last_write` and `inv.batt` off the objects the
   plant moved, never off the arguments the detector was handed, which would
   compare the swap against itself:
     - part 3, the N>=2 trip: "commanded {stood:+.0f} W against its own
       measured power {meas:+.0f} W", plus the persisted namespaced copy;
     - part 7, the N=1 controller-driven trip: "commanded {stood:+.0f} W
       against a meter reading {grid:+.0f} W", plus the namespaced key AND the
       flat rollback mirror;
     - a PRECONDITION on each that the two operands are different numbers of
       opposite sign - without it a transposition produces the same string and
       the check is decoration.

   Measured after the fix: RED on four named checks in test_watchdog.py, GREEN
   in the other twenty files. M11 (the site swap) re-measured on this tree:
   still red. Round 1's and round 2's kills are intact.

2. A FALSE STATEMENT ROUND 2 INTRODUCED, AND IT WAS WORSE THAN REPORTED.
   Section 4 said "three of these left the whole suite green - M1, M2 and M3 -
   and the remaining seven were caught by SAFETY-30's own N>=2 checks". Round
   1's vaguer wording was harmless; naming three made it specific and wrong.

   Re-measured mutation by mutation on clean release/1.0 @ bbc903b, each on a
   fresh copy, bytecode purged, byte delta and fingerprint printed, FULL 21-FILE
   SUITE each time:

     M1  +24 B  fp 362374cf...  21/21 PASS - SURVIVOR
     M2   +9 B  fp 86573e74...  21/21 PASS - SURVIVOR
     M3   +4 B  fp 59fa8815...  21/21 PASS - SURVIVOR
     M4   +9 B  fp 43d852be...  21/21 PASS - SURVIVOR
     M5  +16 B  fp 58d26de8...  RED  test_watchdog.py, 3 checks
     M6   +1 B  fp 407ddb5f...  RED  test_watchdog.py, 3 checks
     M7  -11 B  fp 2a635a4e...  21/21 PASS - SURVIVOR
     M8   +6 B  fp b21eed89...  21/21 PASS - SURVIVOR
     M9   +6 B  fp 0973d3ca...  21/21 PASS - SURVIVOR
     M10  +7 B  fp 0e7b7a4f...  21/21 PASS - SURVIVOR

   EIGHT survived, not three - and not the four a reviewer proposed either.
   The corrected sentence is in DECISIONS section 4.

   AND THE TWO THAT WERE CAUGHT MAKE THE CARD'S CASE. M5 (`sum(abs ...)`) and
   M6 (`-sum`) are the only two entries that reverse the SIGN. Every other one
   changes only the MAGNITUDE, and `_sign_site` - the suite's only N>=2 site
   fixture before this card - runs shares of about -2500 W each against a 320 W
   gate, so sum / mean / max / min / sorted[-1] / [0] / self.target / half /
   double land on -2500, -2500, -2500, -2500, -2500, -2500, -2500, -1250 and
   -5000 W: nine numbers, ALL ON THE SAME SIDE OF THE SAME THRESHOLD. The
   pre-existing coverage could see a sign and nothing else.

3. THEN THE THING THAT WOULD HAVE CAUGHT BOTH: the SYMMETRIC-PREDICATE FAMILY,
   enumerated by machine rather than by hand for a third time.
   `tools/symmetric_message_scan.py` renames each parameter pair, erases every
   formatted string, canonicalises the commutative operators and iterates to a
   FIXPOINT - the symmetry is usually one call deep, and a single pass reports
   an EMPTY family on a tree whose answer is already known. A second census
   covers sentences the CALLER builds. Both print their own blind spots,
   including the one way the scan OVER-reports.

   It found one open survivor this card does not close and now discloses:
   rail_unreachable()'s dev_min/dev_max at main.py:3208 - 0 bytes, 21/21 green,
   a status-page NOT COVERED row - and twelve unpinned caller-built sentences,
   including SAFETY-31's `circ_reason`, which is the same shape and is also
   persisted and re-read after a restart. DECISIONS section 7 has the list, the
   pinned status of every member, and what the instrument cannot see.

No app/ code changes. MUTATION.md gains habit 15.

Claude Opus 5 fef6ef20a4 UX-01: translate the add-on config, and order it by task
checks / unit (pull_request) Successful in 5m1s
The add-on had NO translations/ directory, so Home Assistant fell back to
rendering the raw option KEYS. An operator opening Configuration read
`unit_sign_disagree_w`, `saturation_cycles`, `integrator_max_w` - seventy of
them, in file order, with no description and no way to tell a constant derived
from 1890 closed-loop test runs from their own inverter's rating.

⚠️ PRESENTATION ONLY. Not one default, not one schema range and not one line of
behaviour moved. The 175 non-comment lines of config.yaml are byte-identical to
release/1.0's, reordered; the only comment lines that changed are the group
banners and five sentences whose "above"/"below" the reorder made false.

* translations/en.yaml and translations/nl.yaml: a name and a description for
  all 70 options and all 7 per-entry keys of the `inverters:` repeatable
  section. The Dutch is written for a Flemish homeowner - afname/injectie,
  kwartierpiek, capaciteitstarief - not transliterated from the English.
* ⭐ Every derived constant says WHERE IT CAME FROM and whether to touch it.
  `unit_sign_disagree_s` cites its 1890 closed-loop runs (SAFETY-30);
  `circulation_w` its 924 runs and the measured 400 W knee (SAFETY-31);
  `meter_freeze_s` its 2399 s capture (SAFETY-18); `bms_soc_floor` register
  0x0560. The two numbers that are the operator's - max_w and peak_cap_w - say
  "THIS IS YOUR NUMBER". `cycle_cost_threshold_eur`, which is neither, says it
  is an open product question (OPT-08).
* config.yaml reordered into task order in BOTH halves, comments carried with
  their keys: hardware -> meter -> ratings and limits -> tariff -> maintenance
  -> safety -> advanced.
  ⚠️ test_inverter.py:1788's trap is PRESERVED: the nested per-entry `max_w:`
  still precedes the flat one under `schema:`, and `inverters: []` still ships
  in the `options:` half. Moving the nested block below the flat one is a 1-byte
  edit; it was run and goes red in test_inverter.py and test_translations.py.
* tools/supervisor_shape_probe.py section F MEASURES the result against
  ghcr.io/home-assistant/amd64-hassio-supervisor:2026.08.0 - Supervisor's own
  _read_app_translations(), its own UiOptions, and the frontend's label
  resolution transcribed from the shipped bundle - and prints every rendered row
  in both languages. `all cases passed`, exit 0.
* ⚠️ ONE MEASURED NEGATIVE RESULT, NOT GLOSSED: the per-entry keys inside the
  `inverters:` section still render RAW on frontend 20250925.1, because a
  list-of-objects goes to ha-selector-object and the converter sets no `label`
  and no `translation_key`. The `fields:` translations are shipped and validated
  - that is Supervisor's own shape for this - but this card does not claim they
  reach the screen. The `inverters` label and description do.
* test_translations.py: a translation naming a non-existent option, or an option
  with no translation, fails CI - both directions, both languages, top level and
  per entry. Mutation-tested BOTH WAYS: eleven in-process mutations each
  required to NAME the key they broke, plus a negative control; six more run on
  disk through the purge-and-re-read protocol. Two of the eleven are the ones
  that cost the WHOLE FILE rather than one label - an unrecognised top-level
  block, and a `network:` value that is not a string. Supervisor drops a file
  that fails SCHEMA_APP_TRANSLATIONS with only a log warning, so those silently
  return the entire tab to raw keys; neither is reachable through the
  `configuration:` coverage, which is why they were hunted for and closed.
* tools/translations_lint.py is the hand parser CI needs (no PyYAML in the
  add-on image) and the probe grades it, key by key and string by string,
  against Supervisor's own loader. It is strict and RAISES rather than skipping;
  nine malformed shapes prove it.

Full 20-file suite green (19 existing + test_translations.py).

adminandClaude Opus 5 19decf433f SAFETY-32 round 5: stop closing sites, build an instrument that finds its own scope
checks / unit (pull_request) Successful in 4m59s
Rounds 2, 3 and 4 each closed exactly the survivor they were handed and each time
the reviewer found the same shape one step over: the reduction, the call site, the
sibling argument, and now the sibling MODULE. Round 4's enumeration stopped at the
`Controller` class boundary; round 5's four blockers were reductions in validate.py,
over a list DERIVED from the roster three calls away from it. Closing four more sites
by hand would have produced a fifth rejection, so this round widens the instrument
instead and lets it enumerate.

⚠️ THE BLOCKERS ARE NOT EQUIVALENT MUTANTS - a safety refusal disappears, verified by
calling the shipped validator both ways on the real tree:

  roster max_w 5000 (inverter-a) beside 2000 (inverter-b), sign_disagree_w 3000
    clean                        -> 1 problem, "...max_w (inverter-b) is 2000 W, so the
                                    SAFETY-02 sign-disagreement watchdog can never fire"
    min(caps[:1])          +4 B  -> 0 problems. The site STARTS.
    caps_ix[:1]            +4 B  -> 0 problems.
  the SAME roster with the small cap FIRST (2000, 5000)
    clean                        -> 1 problem, naming inverter-a
    min(caps[-1:])         +5 B  -> 0 problems.

⚠️ AND THE ONE-ROSTER FIXTURE COULD NOT HAVE SEEN THAT. On [5000, 2000] the `[-1:]`
mutant still refuses, because last IS min there. A fixture of N members cannot separate
two reductions that agree on N members - which is why the behavioural half below is a
SET and not a roster.

THE INSTRUMENT (test_peakguard.py part 12j, widened past `Controller`)

Every `.py` under app/ is read off disk and parsed - NO MODULE IS NAMED IN THE CHECK -
and the roster is found by transitive closure from ONE seed, the `inverters` option key:
through returns, through lists ACCUMULATED in a loop over a roster (which is exactly
what `caps`, `roster` and `problems` are, and what round 4's rule could not express),
through attributes and properties, and THROUGH CALL ARGUMENTS, which is how it walks
into peakguard, arbiter, allocator, circulation, maintenance and store without being
told they exist. A slice of a roster stays a roster so a mutation cannot cut the taint;
an index is one unit and does not.

  183 roster reductions across 9 modules, out of 23 files parsed:
  main 96, allocator 24, validate 19, arbiter 14, circulation 10, maintenance 10,
  peakguard 4, inverter 3, store 3.  14 modules reduce over no roster at all.

⚠️ THE HAND-WRITTEN MODULE LIST WOULD HAVE BEEN WRONG IN BOTH DIRECTIONS. It named
watchdog.py, which reduces over no roster at all (SAFETY-30's sign watchdogs are
strictly per-unit), and omitted maintenance.py and store.py, which both do. A vacuous
claim about one module and no claim at all about two others - which is the argument for
computing the scope, made with data.

The pin rediscovers ALL FOUR blockers without being told where to look, and finds a
FIFTH beside them (validate.py:783, rule 5's own message) that no review round named.
Its counterfactual runs at two depths: every enumerated site's expression mutated with
each of the four cuts this card has been defeated by (183 x 4 = 732 spellings, all
reported), and `[:1]` written into app/validate.py at each blocker position with the
WHOLE analysis re-run over the mutated source.

THE SWEEP, AND THE NUMBER THAT MUST NOT BE QUOTED ALONE

All 183 sites mutated to `[:1]`, +4 B each, against the full 19-file suite in
goodwe-addon-ci (:ro, -B, fresh rsync per mutant, 0 .pyc before and after - a read-only
mount cannot write one): 183/183 RED. ⚠️ That is TAUTOLOGICAL on its own, because the
pin makes every slice red. So the 51 whose first red was test_peakguard.py were re-run
with the pin NEUTRALISED:

  145 of 183   a behavioural fixture separates the site from a slice of itself
   38 of 183   ONLY the structural claim. Behaviourally UNGRADED.

All 38 are listed by site with what a `[:1]` there would cost, in the DECISIONS record
and in part 12j itself: 15 are rows and counts on the operator's page, 3 are
`len(targets)` arithmetic beside a write path that IS graded, 6 are allocator internals
ALLOC-01 reaches but not with enough units to separate. NONE of the 38 is closed
behaviourally by this card and none is counted as covered.

THE BEHAVIOURAL HALF, because a shape pin grades an identity and never a meaning

test_validate.py grows a ROSTER SET for the three rules that reduce over
`unit_caps_indexed()`: widths 2, 3, 4, 5 with the one small cap at EVERY position,
14 rosters x 3 rules = 42 runs of the real validator, each asserting the refusal fires
AND names the unit the number came off. Beside it a COMPUTED family table of twelve
candidates - max, first, last, the mean, [:1], [-1:], [:2], [:3], [1:], [:-1], [::2] -
each compared against what the shipped validator actually answered on the same roster.
Only `min` agrees everywhere; a member no roster kills is printed as a NAMED SURVIVOR.

⚠️ A THIRD RULE WAS READING THE FLAT `max_w`, AND IT IS SAFETY-30's

Found by reading the three branches side by side, NOT by the pin - and said that way
because it is the shape of what the pin cannot see. `unit_sign_disagree_w` was graded
against `_number(opts, "max_w", 2000.0)`, three lines under a branch that had already
stopped doing that. Both directions were measured before the fix:

  two 2000 W units + a leftover `max_w: 5000` + unit_sign_disagree_w 3000 -> 0 problems.
  The site started, the status page said `armed`, and the per-inverter watchdog could
  not trip on EITHER unit. Identical sentence to the blocker, one branch over.
  two 5000 W units with NO flat key -> REFUSED against a 2000 W default the operator
  never wrote, for a threshold both units can reach.

It takes the same `weakest` the branch above takes and names the same unit. At a roster
of one `unit_caps()` is `[max_w]`, so the shipped single-inverter refusal is the same
comparison, the same boundary and the same sentence.

B1-B6 are caught by the BEHAVIOURAL set in test_validate.py, before the pin is reached.
B7 is a deliberate no-op control: `max(0.0, weakest)` is `weakest` for weakest > 0, and
it stays green, so the battery is not merely red for everything.

R3a is a ZERO-byte delta, so the shipped function was called both ways as well:
  packs floors [15.0, 30.0, 20.0], peak_soc_floor 15
  binding_soc_floor(...) = 30.0   the 0-byte mutant would answer 15.0   (+15.0 pp)
  -> the site would discharge to 15 % while pack-b's own BMS cuts out at 30 %.

⚠️ PRODUCTION IS DEGENERATE ON THE FLOOR AXIS. SPIKE-04: pack A and pack B BOTH floor
at 10 %, so a differing floor exists ONLY in the fixtures. That is the argument for
keeping them, not for simplifying them - collapsing them deletes the only data in this
repository that can see the reduction at all. Restated in config.yaml's example, in the
probe and in the fixtures.

⚠️ INVERTER B DOES NOT PHYSICALLY EXIST (~2026-09-12). Every second-unit figure here -
4600 W FROM ITS DATASHEET, 15 % illustrative, the whole roster SET - is SIMULATED and
labelled. Only inverter A's 10 % is read off hardware.

REBASED onto 67e649a. Two conflicts with SPIKE-04a, both in the blocks this card had
rewritten (config.yaml's roster example and the probe's C/D sections). Resolved to carry
BOTH claims, and the probe was RE-RUN rather than hand-merged: `all cases passed` on
ghcr.io/home-assistant/amd64-hassio-supervisor:2026.08.0, transcript updated with the
date. MUTATION.md habit 8 - a committed transcript stitched together out of two runs is
not a measurement.

Suite: 19/19 green in goodwe-addon-ci, mounted :ro, bytecode purged and verified 0
before and after. CI-06: test_peakguard.py run four times in isolation, green each time
(288 ok lines); test_validate.py three times, green each time.

MUTATION.md gains habits 12 and 13: build the instrument once the same shape has been
found twice AND make it discover its own scope, and say what the instrument cannot see
with sizes in the same breath.

adminandClaude Opus 5 f9e7fbf86d SAFETY-32: bms_soc_floor per pack, rule 8 per unit
`bms_soc_floor` describes A BATTERY, not a site. At two packs of different
models the cut-outs differ, and one number for both graded the shallower pack
against the deeper one's BMS - so a site with cut-outs of 10 % and 30 % under
`peak_soc_floor: 20` STARTED, and the guard would command a forced discharge
that pack B's BMS, not the operator's floor, is the thing that stops. That is
rule 8's own failure mode, reached through rule 8.

Scoped to the card's third bullet, per its PM PROOFREAD: the aggregate
anti-windup (DEV-02) and per-instance `achievable_w` (CFG-04) were verified as
already shipped and are untouched.

* config.yaml: `bms_soc_floor: int(0,50)` REQUIRED per `inverters:` entry.
  Nothing is inherited; the flat key stays the single-inverter shape's own
  cut-out. A per-entry DEFAULT was declined - a default is one number for every
  pack, which is this card's defect - and the decision is recorded.
* inverter.py: `Inverter.bms_soc_floor`; an entry that states none gets None,
  not a borrowed number and not 0.0 (the most permissive value the key has).
* peakguard.py: `Pack`, `pack_floor_pct()`, `pack_permissions()`,
  `binding_soc_floor()`. `discharge_permitted()` is unchanged and is still the
  one place the question is answered.
* validate.py: `unit_bms_floors_indexed()` carries the ROSTER index; rule 8
  grades EVERY unit and NAMES the one it refuses. Graded with the offender
  SECOND and with the same two numbers in the other order.
* main.py: `Controller.packs`; `decide(soc_floor=...)` is the per-pack
  reduction of the same option; the floor-limited notification names the pack
  that stopped the site. `pack_floor_soc` - the emptiest pack, and its
  None-on-missing behaviour - is untouched.
* tools/supervisor_shape_probe.py: RE-RUN and repaired. The required key broke
  §C and left §D printing PASS on a refusal about a different key. §D is now an
  isolated counterfactual over an accepted merged baseline, one key varied,
  asserting the key name. `all cases passed` on 2026.08.0.

Stated rather than hidden: under any config rule 8 accepts the per-pack FLOOR
reduces to `peak_soc_floor` for every pack. The reduction is written for
`unit_caps_indexed()`'s reason and graded on both sides - 1775 rule-8-valid
pairs answer the option, the pair rule 8 refuses answers the cut-out.
`peak_soc_floor` is still one number for the site, so the "deeper pack
needlessly withheld" half is filed as an open question, not closed.

Full 19-file suite green. Twelve source mutations through
tools/mutation_run.sh: eleven red, one argued survivor. The battery also found
`_flat_bms_floor()` defaulting in two places, each covering for the other.

No measurement of inverter B appears anywhere: it does not exist yet. Every
second-pack figure is simulated and labelled.

glenn schrooyenandClaude Opus 5 a9993aeda2 SPIKE-04a: inverter B is 4600 W FROM ITS DATASHEET, and the copies are pinned
checks / unit (pull_request) Successful in 4m51s
The desk half of SPIKE-04. No control behaviour changes; this is documentation
and the check that stops it drifting again.

Three places stated inverter B's rating - config.yaml's commented roster
example, DOCS.md's, and tools/supervisor_shape_probe.py's "a blob an operator
would POST" - and all three said 3000 W, a number nobody had measured or read
off anything. The owner supplied B's model and serial on 2026-09-04: a GoodWe
GW5048D-ES, serial `55048ESU22AW0992`, max charging and discharging power
4600 W. Serial characters 6-8 are `ESU`, platform 105 / AA55, so SPIKE-01 does
not gate this site. All three copies now read 4600.

⚠️ 4600 W IS FROM A DATASHEET AND IS NOT A MEASUREMENT, and the one ambiguity
is recorded rather than guessed. The datasheet prints it under BATTERY INPUT
DATA, so it is probably DC, while max_w is graded against 0x0518 - the
inverter's own AC power. If it is DC the AC ceiling is nearer 4324 W. Neither
reading is written in as fact; SAFETY-20's min(max_w, dev_max) already bounds
it correctly under either, once dev_max is read off the unit, so `max_w: 4600`
is what an operator should configure today. goodwe/NOTES.md §1.1b carries the
full record with the date and the method on every figure.

A NEW CHECK, BECAUSE A DOCUMENTATION FIX WITHOUT ONE DRIFTS AGAIN.
test_validate.py now pins all three documented rosters: findable, in agreement,
and equal to 4600 - with an explicit len(...) == 3 guard so that a regex which
stopped matching cannot leave "they all agree" green on the two sites still
read. It also grades the PROVENANCE beside the number (the datasheet, the
0x0518 it is graded against, and the 4324 W the DC reading would make it)
WITHIN 2500 characters of the roster rather than file-wide.

⚠️ The first version of that provenance check searched whole files and was
ALREADY VACUOUS on two of them: 0x0518 appeared once in config.yaml and once in
DOCS.md before this card, for unrelated reasons, so `"0x0518" in src` was green
no matter what happened next to B's rating. That is a check whose data cannot
reach the failure it names, in the file that exists to complain about them. It
is fixed, and the window is what fixes it - deleting the caveat beside the
number now goes red even where the same token survives elsewhere in the file.
The windowed version immediately found that the DOCS.md caveat did not name
0x0518 at all; DOCS.md now says it.

Four mutations, bytecode purged and counted at 0 before and after each, all
RED (two of them 0-byte deltas that change a printed answer):
  M1  probe's operator blob 4600 -> 3000        0 B   RED (value + agreement)
  M2  DOCS.md's DC/AC caveat deleted         -157 B   RED (provenance)
  M3  config.yaml alone 4600 -> 4324            0 B   RED (agreement)
  M4  probe entity renamed, regex finds nothing       RED (the vacuity guard)
Restored, green again. The probe itself was re-run against Supervisor
2026.08.0's own AppOptions validator with the 4600: all cases passed, exit 0.

⚠️ THE TEST FIXTURES KEEP 3000 W ON PURPOSE AND NOW SAY WHY AT THE LINE.
test_inverter.py, test_maintenance.py, test_peakguard.py and test_watchdog.py
build a second inverter at 3000 W against A's 5000 W. The only property those
checks consume is that B's number is unmistakably not A's, and the real pair is
a 400 W gap - narrower than slew_w, inside the range where an off-by-one-unit
bug and ordinary control arithmetic produce indistinguishable numbers.
Collapsing them onto the real values would buy realism those checks do not use
and cost them their separating power, which is exactly what test_peakguard.py's
own §10g PRECONDITION exists to prevent. Their comments no longer call 3000 W a
hypothesis about B's rating; they call it illustrative, and not a placeholder
either - the placeholder era ended on 2026-09-04.

Also recorded in the changelog for the cards that own them: 94 % battery-to-AC
=> ~88 % round trip => ~360 W burned continuously to circulate 3 kW, which is
the number SAFETY-31 argues its threshold from without having one; < 13 W night
self-consumption per unit, which nothing accounts for; and the A/B asymmetry in
opposite directions (~33 % more energy, ~8 % less power), which means MAINT-05's
12 h drain timeout was derived on A and should be re-checked against B.

⚠️ Honest survivors:
- goodwe/NOTES.md §1.1b, where all of this is actually recorded, is graded by
  nothing here. Rewriting its 16 occurrences of 4600 to 3000 and turning every
  FROM DATASHEET label into MEASURED ON THE UNIT leaves all 19 files GREEN.
  This CI cannot fetch admin/goodwe - private, and GITHUB_TOKEN is minted for
  this repository only, as .gitea/workflows/checks.yml already states - so the
  cross-repo check is not buildable here.
- No check can see whether 4600 is the RIGHT number. Everything above pins a
  datasheet reading against itself. Only the bench half of SPIKE-04 can say
  whether the unit agrees, and the DC-vs-AC ambiguity is the live example.
- The constant is still named B_RATING_HYPOTHESIS in four test files, which
  reads as a hypothesis about B's rating when it is now an illustrative
  fixture. It is left alone deliberately: renaming ~20 sites across
  test_peakguard.py and test_inverter.py would collide hard with the open
  SAFETY-32 pull request, which rewrites 1255 lines of the first. The comment
  directly above each definition says what the value is and is not.

Suite: 19/19 green in goodwe-addon-ci, mounted :ro, bytecode purged and
verified 0 before and after.

glenn schrooyenandClaude Opus 5 22c016fadd CFG-04 fix round: the probe now measures the key it is cited for
checks / unit (pull_request) Successful in 4m33s
Review blocked this on ONE finding, and it was in the EVIDENCE, not the code.
The design and the shipped behaviour are unchanged.

THE INSTRUMENT DID NOT MEASURE WHAT FOUR DOCUMENTS SAID IT MEASURED

tools/supervisor_shape_probe.py section B validated the RECONSTRUCTED LIVE
options blob - which is missing many required keys that have nothing to do with
this card. Its refusal therefore named whichever of THOSE the validator reached
first: the committed transcript recorded `meter_freeze_s`, the reviewer's run
printed `p1_phase_export_entities`, and a run today printed `sign_disagree_w`.
The string those documents quoted - `Missing option 'inverters' in root` - was
never produced by the instrument.

And section B asserted a bare `not ok`. Any refusal at all satisfied it, so
deleting `inverters: []` from config.yaml left it printing PASS: the probe could
not detect the one regression it is the committed evidence for.

THE UNDERLYING CLAIM IS TRUE AND IS NOW MEASURED PROPERLY

Section B is an ISOLATED COUNTERFACTUAL now: the full shipped `options:` block
(expect accept), and the SAME block with `inverters` removed and nothing else
varying (expect refusal). One key differs, so the refusal has nowhere else to
come from - and the assertion is on the KEY NAME IN THE REFUSAL STRING, so the
line goes red if the refusal is ever about a different key. The probe also exits
non-zero when any case fails; without that a transcript is only evidence to
someone who reads it.

The old live-blob case survives as section B2, relabelled for what it is: an
incomplete reconstruction whose RAW half is refused for unrelated missing keys,
kept because its MERGED half genuinely demonstrates what App.options is.

VERIFIED BY BREAKING IT, WHICH IS THE WHOLE POINT

`inverters: []` deleted from config.yaml, probe re-run against
ghcr.io/home-assistant/amd64-hassio-supervisor:2026.08.0:

  == B. THE LOAD-BEARING ONE: an options blob with no `inverters` key ==
    FAIL  the shipped `options:` block validates AS IT STANDS - ...
          Missing option 'inverters' in root in GoodWe RS485 Controller
  ...
  == 2 CASE(S) FAILED ==

exit 1. Key restored, same image, same command: `== all cases passed ==`, exit
0. The transcript in DECISIONS is that restored run, re-run today, not the old
one.

THE FOUR MIS-CITATIONS

DECISIONS/CFG-04-inverter-roster.md section 4's "section B shows both halves"
sentence and its line-103 transcript; CHANGELOG.md; test_inverter.py's part-9
comment and its part-12 mutation row; and the PR description. All now attribute
the string to section B and say plainly what section B2 does not show. The
part-12 row additionally records that the probe was blind to that mutation until
review, because a mutation table that lists a defeat nothing catches is the
failure this repository keeps finding.

MUTATION.md gains it as the sixth instance of "the check's data cannot reach the
failure it names" - the first found OUTSIDE the suite, in a committed evidence
artifact, because nothing in that document had ever been pointed at tools/. Three
habits with it: assert on the CONTENT of a refusal rather than that one happened;
vary ONE thing, from an ACCEPTED baseline; and treat a committed transcript as a
check subject to the mutation battery.

TWO NON-BLOCKING FINDINGS, ALSO FIXED

  validate.py rules 5 and 6 NAMED THE WRONG INVERTER. `unit_caps()` SKIPS an
  entry with no usable `max_w`, so caps position i stops being roster position i
  the moment one entry is malformed - and rule 5 fed `caps.index(weakest)` to
  `_unit_label()`, which indexes the roster, while rule 6 paired `caps[0]` with a
  hard-wired `_unit_label(opts, 0)`. Right number, another inverter's name: an
  operator sent to the wrong device by the message that exists to stop that. New
  `unit_caps_indexed()` carries the roster index with the cap. It is latent -
  rule 9(d) refuses such a config in the same pass - but that was a property of
  today's rule ordering, not of the code, and validate_startup_config() is also
  sim/inject.py's entry point. Part 10 gains a check that asserts the fixture
  really does desynchronise the two lists, then that both messages name the right
  unit, then the counterfactual: the OLD expressions, on that same config, still
  evaluate to the wrong names.

  DOCS.md called a downgrade "safe". True of the SCHEMA - the older schema drops
  the key with a warning - and incomplete about the ADD-ON: rule 9(e) requires the
  flat `setpoint_entity` be cleared when a roster is declared, so a config that
  downgrades cleanly is by construction one whose flat actuator is blank, and the
  older version has nothing to write to. Confirmed by running release/1.0's own
  validate_startup_config() on that blob: one refusal, naming setpoint_entity.
  Recoverable and loud, but an outage until a field is refilled. The note says so
  now, and tells the operator to write the entity down before downgrading.

19/19 green in the goodwe-addon-ci image.

adminandClaude Opus 5 6b85acb0f1 CFG-04: an operator can declare a second inverter, and the shape was measured
checks / unit (pull_request) Successful in 4m30s
DEV-02 made every per-device value per-instance - rating, SoC, watchdogs,
heartbeat, store keys - so the code stopped assuming one inverter. The options
schema did not. `build_roster()` returned a list of exactly one and said so in
its own docstring, and there was no `inverters:` key for an operator to write,
so the roster could only ever be a roster of one.

THE SHAPE, AND WHY IT WAS MEASURED RATHER THAN CHOSEN

config.yaml had no list-of-objects anywhere, and `static_profile` carries a
whole tariff structure as a JSON string in a `str?` precisely because a nested
schema was doubted. That is a question about somebody else's software, so it was
answered by running it: `tools/supervisor_shape_probe.py` (committed) runs
Supervisor 2026.08.0's OWN `AppOptions` validator and `SCHEMA_APP_CONFIG`, out
of the release image, against this repository's config.yaml. 2026.08.0 is the
version the live install reports. The full transcript and the argument are in
DECISIONS/CFG-04-inverter-roster.md.

It accepts the list, enforces per-entry types, refuses a missing `name` /
`setpoint_entity` / `max_w` BY NAME, renders the option in the UI as a
repeatable section, and drops the key with a warning under an older schema - so
a downgrade is not the forward trap in reverse.

⚠️ AND THE `inverters: []` DEFAULT IS LOAD-BEARING, WHICH IS THE MEASUREMENT
THAT MATTERED MOST. Supervisor answers `Missing option 'inverters' in root` for
an options blob that has no such key - which every existing install's has, since
the key did not exist when they were written. `App.options` is the shipped
`options:` block deep-merged with the operator's stored one, so the empty
default is the difference between an upgrade nobody notices and an add-on that
cannot start with a schema pinned to the version that would fix it. That is
docs/deploy-rollback.md §4's trap in the FORWARD direction, found before it was
sprung. The merger was checked too: lists override rather than concatenate, so a
non-empty default could not have grown a roster behind the operator's back.

NOTHING IS INHERITED, WHICH IS DEV-02 RESTATED AS A CONFIG RULE

`name`, `setpoint_entity` and `max_w` are required of every entry. An entry that
omits `soc_entity` has no SoC sensor; it does not borrow the flat one. A
three-line fallback would have rebuilt the sibling-grading defect DEV-02 spent a
card removing, in YAML. Defaults still live in exactly one place (CFG-03):
there is no per-entry default anywhere, because there is no optional per-entry
number. A flat `setpoint_entity` left set beside a declared roster is refused
rather than ignored - it names an actuator nothing will write.

TWO PERMISSIVE READERS IN SHIPPED CODE, AND THREE MORE IN THE CHECKS

  validate.py rules 5 and 6 compared their thresholds against the FLAT `max_w`.
  At a roster of two 2000 W units with `max_w: 5000` left over from a
  single-inverter install, `sign_disagree_w: 3000` passed rule 5 while
  SAFETY-02's watchdog could fire on NEITHER unit - rule 5's own failure mode,
  reached through rule 5. They read `unit_caps()` now, which at one inverter is
  `[max_w]` exactly.

  main.py's `run_control()` re-ran the device-rating check behind
  `if self.o.get("setpoint_entity")` - the flat key, which a roster leaves blank
  - so on a two-inverter site no inverter's `max_w` was graded against the
  device it is written to, and the skip was silent. `validate_unit_ranges()`
  grades each unit against its own ESPHome and runs unconditionally.

  test_peakguard.py's `read_option()` and `_schema_bound()` and
  test_inverter.py's `read_schema_max()` matched a STRIPPED line and took the
  first hit, so the nested per-inverter `max_w:` began outranking the flat one -
  silently, and correctly, because the two bounds are the same int(100,5000)
  today. A reader that is right by coincidence is this project's named failure
  mode. All three are anchored at exactly two spaces now; the file's two halves
  disambiguate `peak_cap_w` instead of first-match, and an ambiguous key raises
  rather than picking one. test_tariff.py's copy of the idiom went with them.

THE AUDIT IS A CHECK, NOT A PROMISE

test_inverter.py part 11 finds every config.yaml-reading function in the suite -
transitively, because two of the readers CFG-04 had to change never name the
file - EXECUTES each against a synthetic two-inverter config.yaml whose
per-inverter numbers differ from its flat ones, and fails if any answers with
the per-inverter value. The table is not maintained by hand: the signature
decides, so the eleventh reader is named on its first run. config.yaml declares
`inverters:` BEFORE `max_w:` on purpose and part 11 asserts that ordering, so
the trap stays baited.

SAFETY-28's `actuator_writers()` needed no change - it was already a structural,
case-folding census - but until now there was no configuration in which two
writers on one actuator could be WRITTEN DOWN. There is now, and it is refused.

VERIFIED BY BREAKING IT

Ten mutations run through tools/mutation_run.sh and observed red, listed in
test_inverter.py part 12 with the check that bites each. Two survived the first
run and the CHECKS were changed, not the table: the inheritance check had blank
flat keys, so "inherited" and "not inherited" were the same empty string; and
the `run_control()` check asserted a SOURCE LINE was present, which re-indenting
it does not remove. Both are recorded in MUTATION.md's "the check's data cannot
reach the failure it names" section, which now carries two more habits: assert
on behaviour rather than on source text, and give a check whose failure mode is
a hang a deadline.

19/19 green in the goodwe-addon-ci image. The one-inverter path is byte-
identical: the whole existing suite runs unmodified against it.

Version bumped to 0.6.0 - the Supervisor keys the built image by `version:`, so
a schema change without a bump is a schema nobody reads.

glenn schrooyenandClaude Opus 5 e306c74cb8 DEV-02: per-instance inverter objects, so nothing is graded against a sibling
checks / unit (pull_request) Successful in 4m15s
Every piece of per-device state in the Controller was a scalar, and several of
them are safety inputs. app/inverter.py introduces an `Inverter` that owns its
entities, its rating, its device range, its SignWatchdog, its last_write and
its last_beat, under store keys namespaced by unit name. The Controller holds a
list of them and keeps only what is genuinely site-level: the P1 reading, the
site integrator, and the tariff quarter.

WHAT THE SCALARS WERE SILENTLY ASSERTING

  dev_min/dev_max   one pair, read from one setpoint_entity. A second
                    inverter's rating was NEVER READ AT ALL, so its clamp, its
                    freeze rail and the peak guard's achievable_w were the
                    first one's numbers.
  soc               one reading into the maintenance FSM, SAFETY-24's pack
                    floor and arbitrage's bounds. An average lets the emptier
                    pack be driven below its own floor.
  sign_wd           ONE SignWatchdog, whose own docstring says "one instance
                    per actuator", latched under FLAT store keys - so a trip
                    caused by B latched A across restarts and one operator
                    press cleared both.
  last_beat         one deadline and one serialised hass.call(), so a hung
                    write to A ate B's 30 s layer-1 budget.

actual_w BECAME SITE LEVEL WHILE THE READINGS BECAME PER-INSTANCE, and those
are opposite directions on purpose. compute()'s anti-windup test is
`abs(prev_w - actual_w) > saturation_w` with prev_w the SITE target, so feeding
it one inverter's power compares a site number against a unit number, trips the
saturation freeze permanently and leaves a standing grid error. Measured on
admin/goodwe's two-master rig (tools/alloc_sim.py --splits, 2 kW load, 40
cycles), worst |delta| between splits at the meter:

    gain    one unit's power      the site sum
    0.2           510 W                0 W
    0.4           250 W                0 W
    0.6            50 W                0 W

That was ALLOC-01's disclosed finding; test_alloc.py part 8 kept its stimulus
and now grades the other row.

THE STORE MIGRATION IS GRADED, NOT MERELY PERFORMED. sign_tripped/sign_reason
move to unit/<name>/... once, verified by READING BACK what was written, and
the version marker is set only when nothing that carried state was lost. The
flat keys stay in the file so a rollback still finds its latch. And __init__
compares the pre-migration flat latch against what unit A actually came up
with: if the latch did not survive it is RE-ARMED from the legacy value and
shouted about. A latch that silently fails to migrate is a disarmed safety
guard on an install whose state file says it is protected - which is strictly
worse than never persisting it, because now there is evidence saying it is
fine. test_inverter.py part 2 breaks the migration and watches the guard fire.

HEARTBEATS ARE INDEPENDENT AND THE BUDGET IS DERIVED. Each inverter owns its
deadline, the refreshes go out concurrently, and each write is bounded by
WRITE_BUDGET_S = 4 s. The inequality is graded rather than asserted: 4 +
heartbeat_s's schema maximum of 25 < 30, validate.FIRMWARE_INGEST_VETO_S.
Verified by injecting a transport that accepts and never answers.

live_units() ANSWERS HONESTLY. A unit whose every write has been rejected for a
whole layer-1 window is not commandable; the allocator drops it, the survivors
carry its share, the action log names it, and the dropped unit is commanded
0 W rather than left standing on its last share. A roster entry with NO
setpoint_entity is deliberately not handled there - that is a configuration
that cannot be delivered, and it reaches main.py's refusal branch, which is how
that branch keeps a live trigger after this card removed its old one.

AT N=1 NOTHING MOVES. The removed scalars survive as read/write properties of
the sole inverter, so every existing replay runs unmodified - and they REFUSE
at N>=2 rather than answering for the first inverter, which is the tripwire on
a consumer that was never made per-instance.

EVIDENCE. 19 files green. test_inverter.py is new (82 checks). Eighteen
mutations were applied to the shipped modules on a purged tree via
tools/mutation_run.sh and each was observed RED. Two of them SURVIVED first
time and the checks were changed rather than the table: the serialised dispatch
and the shared last_beat both passed while part 6 gathered its own writes and
computed its own `due` list. send_heartbeats() was extracted from run_control()
so the shipped dispatch is reachable by a check at all.

INVERTER B STILL DOES NOT EXIST. build_roster() returns exactly one inverter
from the flat options and is the one function CFG-04 changes; every two-unit
figure here is architecture, and the second rating in the checks is marked a
hypothesis.

glenn schrooyenandClaude Opus 5 186e13ceca ALLOC-01: allocate the site grid target, sum-invariant, never broadcast
checks / unit (pull_request) Successful in 4m6s
ARB-03 left `allocate()` as a documented seam that passed through at N<=1 and
DECLINED at N>=2, with the reasoning recorded at the line: the obvious
placeholder - hand the site target to each inverter - IS the ARCH-01 fault, and
"a placeholder that cannot be told apart from the real thing by any guard we
have is worse than no placeholder". This fills the seam.

WHY A BROADCAST IS A FAULT AND NOT AN INEFFICIENCY. The control primitive is
meter emulation: the master reports a FABRICATED grid reading and the inverter
regulates itself to it, so one number means "the battery moves X W" to this
add-on and "the grid is at X W" to the inverter - an identity that holds only at
N=1. Hand two inverters the same target and each supplies it IN FULL, so the
loop gain at the meter becomes N times the per-unit gain. Reproduced on
admin/goodwe's two-master rig against this tree: -400 W export overshoot at
gain 0.6, and at gain 1.0 - which config.yaml accepts as its documented maximum
- a permanent 4000 W peak-to-peak limit cycle, commands alternating
1000/2000/1000/0 W, with NOT ONE GUARD FIRING. The sign watchdog is evaluated on
every cycle and never trips, because the disagreement flips on alternate ticks
and never holds its 180 s window.

WHAT WAS BUILT. `app/allocator.py`, host-side and strictly above the driver
seam. It consumes intervals and a number and nothing else - no claims, no
priorities, and no measurement, because an allocator that read P1 would be a
SECOND integrator on the site measurement.

  * ENVELOPE CLAMP, from ARB-03 stage 1's `UnitBounds`, read PER TICK. `plan()`
    is a pure function and the module holds no state, so there is nowhere for a
    construction-time envelope to be cached.
  * WATER-FILL by weight, with the surplus of a full unit moving to the others.
    Weights express PREFERENCE, envelopes express PERMISSION: a zero weight is
    honoured while another unit has headroom and overridden when it does not,
    because the SUM is the safety property and stranding capacity behind a
    comfort choice manufactures a standing error at the meter.
  * LARGEST-REMAINDER ROUNDING. The target is rounded ONCE, at the top; every
    sum below that line is integer arithmetic, so it cannot drift. Measured: a
    per-unit round() drifts -125 W over 50 000 ticks at three inverters.
  * THE ALLOCATION RECORD, with `unmet_w`, `dropped` and a per-unit reason.
    `ok` is one boolean for SAFETY-28 to gate on, and `unmet_w` is deliberately
    NOT fused into it - a saturated inverter must not park the whole site.

THE STABILITY PROPERTY IS STRUCTURAL. With sum(a_i) = 1 the gain at the meter is
sum(a_i * g_i), a convex combination of the per-unit gains, so it lies in
[min g_i, max g_i] FOR ANY SPLIT. That is what makes the weights a comfort
choice rather than a tuning parameter, and it is why a bad split cannot
destabilise the site. Graded directly, and measured end to end: 90/10, 50/50 and
100/0 give a bit-identical aggregate trace at the meter, and a gain sweep to 1.0
at every split has a flat tail at all 84 combinations.

THE TWO REFUSALS main.py NOW MAKES, AND WHY THERE ARE TWO. `allocated=False` no
longer means "no allocator"; it means no safe split EXISTS - a mis-routed claim,
an empty envelope set, or a split that could only be made by commanding one pack
to charge while another discharges. Separately, and this guard is the price of
making allocate() succeed rather than something inherited, main.py refuses to
act on a valid split it cannot DELIVER: there is one `setpoint_entity`, so
writing the site target to the one inverter it can reach would over-command that
inverter by exactly the other's share. Commanding a partial site is a worse
instruction than commanding nothing. DEV-02 gives it the second writer.

scope_violations() IS NOW CONSUMED, AND AS A REFUSAL. ARB-03 left it logging
without changing the resolution. A mis-routed claim means the number about to be
divided may itself be wrong, and dividing a number that may be wrong is worse
than not dividing it - the same answer clause 3 already gives a contradiction.
It is NOT promoted into an envelope: a unit-scoped claim that landed on the site
names no unit, so promoting it would mean guessing one, or applying one
inverter's rating to a sibling that does not have it.

AT N<=1 IT IS A PASS-THROUGH, BYTE-IDENTICAL: the share is the site target, as a
float, unrounded and unclamped. All 17 existing suites replay unedited.

test_peakguard.py part 10h and test_arbiter.py part 7 were RE-AIMED, not
deleted. PR #40's reviewer proved that refusal branch was unreachable and
untested once; removing its trigger without giving it a new one would have
rebuilt the hole. Part 10h now drives three real cycles - a deliverable split, a
dead sibling, and every master stale - and grades all three.

KNOWN AND NOT CLOSED HERE: at a roster of two the loop's `actual_w` is one
inverter's power used as a site measurement, because the add-on binds a single
`inverter_power` sensor. That is the SENSING half of the same N=1 identity this
card removes from the COMMANDING half, and it makes the aggregate trace
split-dependent below gain 1.0. Measured with its counterfactual in test_alloc.py
part 8 and tools/alloc_sim.py --splits. It belongs to DEV-02.

Verified: all 18 suites green in the CI image. 16 mutations run through
tools/mutation_run.sh on a purged tree; 13 red, and the 3 survivors are recorded
in test_alloc.py part 12 with the reason each cannot be caught.

glenn schrooyenandClaude Opus 5 7b4877d56d TEST-15: purge the bytecode cache before a mutation run, not after
checks / unit (pull_request) Successful in 3m35s
FCST-03's developer reverted `self.provisional` to `here.provisional`, re-ran,
and reported the mutation as a survivor. It was not one. CPython validates a
cached `.pyc` on (source size, source mtime truncated to whole seconds), and
that edit moved neither number - same length, same second - so the interpreter
loaded the bytecode it already had. Disassembly settled it at the time: the
source read `here`, the running code loaded `self`. A mutation run had graded
code that was not there, with no error and exit status 0.

This does not make the results already on the record wrong. It makes them
UNVERIFIED, and that distinction is the whole card - so nothing here re-runs a
campaign and nothing here quietly assumes the old numbers hold.

REPRODUCED, THEN CLOSED. test_bytecode.py builds a real package whose two
return values are the same length, imports it in a real subprocess, rewrites it
inside the same second (retrying until both writes land in one whole second -
milliseconds, no sleep) and reads back which value ran. Part 1 shows the
interpreter running SELF off a file that says HERE.

AND THE TWO OBVIOUS MITIGATIONS DO NOT WORK. Measured, not read off
documentation: `python3 -B` and PYTHONDONTWRITEBYTECODE=1 are write-side only.
Neither stops an EXISTING stale .pyc being read, and a mutation run always has
one, because the previous run wrote it. Part 2 grades both still running the old
code. The advice in test_control.py's coverage audit led with `-B`; it is
corrected here - the purge is the half that works, and `-B` earns its place by
keeping THIS run from leaving a cache for the NEXT edit to inherit.

NO SLEEP ANYWHERE. One-second mtime resolution is the mechanism, not the enemy.
Waiting it out would slow every run down and would still only cover the edit
somebody remembered to slow down.

THE HARNESS. tools/mutation_run.sh purges, prints a sha256/byte fingerprint of
every app/*.py it is about to grade - so a mutation report can say WHICH source
produced it, which is the reviewer's addition to this card - runs each suite
under `python3 -B`, refuses a tree with no test_*.py (CI-01's rule, for CI-01's
reason), and fails if a cache appears during the run. It takes the tree as an
argument so the infra repo's replay harnesses can call it without being moved.

WHERE IT IS SAID (AC 2). MUTATION.md carries the mechanism, the measurement,
the reporting rules and the survey, and every one of the 16 suites now points at
it from its docstring. That list is DERIVED FROM THE TREE by test_bytecode.py
part 5, so a new suite that joins this directory without the pointer is red -
the same failure shape CI-01's file glob exists to prevent.

CI WAS ALREADY IMMUNE, AND IS DESCRIBED THAT WAY (AC 4). Verified rather than
reasoned: with the checkout bind mounted `-v "$WS:/w:ro"` the interpreter writes
no __pycache__ into the tree at all, and it fails SILENTLY - no error, exit
status 0 - while the same probe on a writable mount produces one. Each job also
rm -rf's its workspace and clones afresh, so nothing crosses between jobs on the
shared runner. PYTHONDONTWRITEBYTECODE=1 is added as belt and braces only: the
`:ro` is one character wide and the next person debugging a write will be
tempted by it. Part 6 grades both ON THE DOCKER COMMAND LINE rather than on the
file - the first draft searched the whole workflow and stayed green after the
flag was deleted, because the comment explaining it still named it.

THE SHIPPED ADD-ON IS NOT AFFECTED and the question is closed:
goodwe_controller/Dockerfile has set PYTHONDONTWRITEBYTECODE=1 since it was
written. There is no deploy-side finding.

THE SURVEY (AC 3), in MUTATION.md, scoped BY THE PROPERTY. The defect is
one-directional - a mutation that never took leaves the suite green, so stale
bytecode manufactures SURVIVORS and cannot manufacture a red - which puts every
"all red, no survivors" claim in the window out of scope, along with mutations
executed in-process (SAFETY-07's B1/B2/B3, test_peakguard parts 7 and 10, where
no source file is edited) and everything run after the purge discipline landed
on 2026-08-31 (SAFETY-24, SAFETY-26, OPT-04, FCST-03's re-run). What is left is
the recorded SURVIVORS from source-edit runs before that date. Two were re-run
here under the harness and both still stand: TARIFF-01's record_block() ignoring
its policy argument, and SAFETY-03's abs() on the clamp limit - 15 suites green
each, on the tree as it stood. The rest are labelled still-unverified rather
than assumed or re-run; each is one harness run to close, and the moment to
spend it is when somebody next touches that module.

OUT OF SCOPE AND RECORDED: the infra repo's sim/ replay harnesses import the
add-on and write bytecode into both trees (goodwe/sim/__pycache__ exists today),
so SAFETY-02's headline replay carries the same exposure. mutation_run.sh takes
a tree argument for exactly that, but the change belongs in that repo and some
of those harnesses want the rig.

RED AND GREEN. Every new check was broken and watched fail: the purge commented
out of the harness turns part 4 red (and its non-vacuity probe already proves
the fixture would mis-grade without it); one docstring pointer removed turns
part 5 red naming the file; `:ro` and the `-e` flag removed from the workflow
turn part 6 red. Full suite green, 16 files, in the CI image on a read-only
mount - the shape the runner uses.

glenn schrooyenandClaude Opus 5 04292c4a08 DATA-01: thirty days of the real meter, and what AC 3 actually measures
checks / unit (pull_request) Successful in 3m36s
TARIFF-01 and SAFETY-07 both merged with AC 3 - "monthly peak held under
the soft limit in >= 95 % of intervals over a 30-day simulation replay" -
honestly unmet, because two days of capture existed and it was believed
nothing longer could be produced. That belief was a true statement about
the past read as a claim about the future: HA's recorder still held the
whole month, and the reason nobody found out is that the 2026-08-25
export was a one-off script that left no artefact.

So the exporter is committed and runnable now.
scenarios/p1-net-30d-2026-08/ is 2026-08-01 to 2026-08-30, 485,841
samples, 30/30 days read, 0 failed, 4.13 MB gzipped, in the schema the
two committed days already fixed.

VERIFIED AGAINST THE DAYS THAT EXIST. `--verify` re-fetches 2026-08-20
and 2026-08-23 by this exact route and reproduces both committed files
BYTE FOR BYTE after decompression (865,024 B / 15,600 samples and
894,387 B / 16,351 samples). The gzip containers differ by design: this
exporter writes mtime 0 so its output is reproducible, where the one-off
wrote a wall clock.

A FAILED READ IS NOT AN OBSERVATION. A day whose read fails writes no
file, is recorded "read": "FAILED", and the run exits non-zero; the
entity is proved to exist through /api/states before any empty day is
believed, because a typo would otherwise answer 200 [] thirty times and
produce a consistent dataset of nothing. Nothing is interpolated, so the
month's 13 gaps (1291 s, 99.95 % covered) and its 3 `unavailable`
samples stay visible as holes.

SIZE: COMMITTED, DELIBERATELY, AND MEASURED. A git bundle of the whole
history goes from 1.58 MB (release/1.0 @ 86c43eb) to 5.28 MB - +3.70 MB,
x3.3 - and a Home Assistant supervisor clones that on every install.
Downsampling was not on the table: meter_max_age_s is 30 s, so any
coarser resample turns real coverage into modelled meter-gap and moves
the number being measured. "Outside the repo with a pointer" is what
already happened and is why this card exists. The files sit in a
SUBDIRECTORY so the non-recursive globs in test_tariff.py part 9 and
test_peakguard.py part 6 do not pick them up - CI keeps replaying the two
small days instead of growing ~50 s per PR.

AC 3, MEASURED OVER 30 DAYS (tools/replay_ac3.py, which must reproduce
test_peakguard part 6's 189/190 to be believed):

  uncontrolled  2847/2879 = 98.89 % of quarters at or under 3500 W
  guarded       2850/2879 = 98.99 %
  month peak    5029.8 W -> 4107.3 W

Met on the ">= 95 % of intervals" reading - and the uncontrolled figure
is the finding, because a month with no controller at all passes it. Not
met on the other reading of the same sentence: 4107.3 W is still over the
soft limit. The guard pulls 31 of the 32 over-cap quarters down but lands
only 3 under the cap, because CEILING_MONTH_PEAK defends the running
month peak rather than the cap once one is set. Both suites' honesty
notes are corrected to point at the month instead of at its absence.
