OPT-11 P1 review: a mode never beats the peak floor; SAFETY-03 kept at the rail
- arbiter: a mode now gives way only as far as a site limit above P_MODE
needs (_unit_modes at N>1, _site_mode at N=1). Before, the modes were
released only when the peak floor bound S, so a trade won above the floor
kept them and placed less than the floor (an Off battery at N=1 went to 0 W
under a 2000 W floor), and a capped grid charge released an Off battery.
While released, held batteries weigh 0 and carry only the shortfall.
- control: a side of the loop bound that reaches the rail is left to the
rail, so SAFETY-03's i_clamped still fires with every battery on.
- opt11_identity: add maintenance scenarios and a 6000-case arbiter digest
(peak floor, trades, maintenance, refusals);

OPT-11 P1: per-battery mode limits, on/off, solar order
A battery's mode is a soft unit limit (source `mode`, P_MODE 35) kept
apart from the hard limits in pre_resolve(). The allocator applies it
only while the site target is decided at or below 35 (new
Resolution.deciding_priority), so the peak floor releases it and a mode
`hi` never meets the site `lo`. At N=1 resolve() applies the same rule
to the site target after stage 2. A mode range without 0 W is dropped
as a software fault, so REFUSE_SIGN stays unreachable from a mode.
compute() gets the loop bound (sum over live units of hard limits with
modes applied), so the loop never asks for watts no battery may give
and the saturation freeze never parks on them. While charging, Leftover
solar weighs 0 so Solar first fills first. Store keys pack_use and
pack_mode per battery, set by two new /action values; Off stops and
skips maintenance with a log line. Minimal Batteries cards (EN/NL).
Off by default (battery_modes_enabled); off, commands are byte-identical

CI-12 round 2: INFRA_READ_TOKEN for admin/goodwe; the pin tracks release/1.0
- checks.yml's infra checkout and infra-pin.yml's admin/goodwe ls-remote use the INFRA_READ_TOKEN secret; the self fetch keeps GITHUB_TOKEN. - infra-pin.yml compares against admin/goodwe refs/heads/release/1.0; STALE message, comments and README follow. - test_control.py / test_alloc.py: drop the claim that CI cannot reach admin/goodwe. - .gitea/infra-pin is DELIBERATELY one release/1.0 merge behind (d84ac01) for the "infra-pin / fresh goes red" proof; the next commit sets it to HEAD.

SAFETY-48: the slew step ceiling reaches the integrator, and what it bounds is the LEAD
`compute()` freezes the integrator with an asymmetric rule and the comment beside it states the requirement outright - "the requirement is that the INTEGRATOR stop accumulating, not only the command" - but `frozen` is computed from ONE signal, `abs(prev_w - actual_w) > saturation_w`, and slew-limiting never enters it. The integrator moves `gain * error` a cycle and the command moves at most `slew_w`, so the integrator outruns the command whenever `|error| > slew_w / gain`: 667 W at the live shape, against a measured median grid error of 1114 W at the onset of a recorded episode. SAFETY-39's retune made it MORE frequent, not less - a smaller step is a lower threshold. ⚠️ THE FORM THE CARD ASKED FOR RAISES THE BILLED QUANTITY, WHICH IS WHY IT IS NOT WHAT SHIPPED. Reusing the asymmetric freeze on a carried slew flag was built from release/1.0's own source and measured over 16.00 days / 256 252 meter instants of the live install's recorder: export 39.61 -> 34.43 kWh, and the worst quarter-hour average OFFTAKE 3739 -> 3935 W with the mean quarter +2.73 W, in five of six plant and tuning variants. A frozen integrator stops at `prev + gain*error`, which undershoots by (1 - gain); for an export that is free and for an import it is offtake, for as long as the ramp lasts. The card said "do not invent a second rule"; the measurement says to, and both sentences are recorded. WHAT SHIPS BOUNDS THE LEAD AT ONE SLEW STEP, inside the branch where the slew actually bound. Same 16 days, same ticks, same disturbance, same plant, same seed: export 39.61 -> 34.07 kWh, wasted throughput 4.67 -> 3.19 kWh, battery sign reversals 2992 -> 2770, median recovery 232 -> 199 s, p99 849 -> 850 s, max 901 -> 898 s, unrecovered 53 -> 31, worst |i_w - prev_w| 9200 -> 800 W - and the worst 15-minute average offtake 3739 -> 3434 W, i.e. the billed quantity IMPROVES. `i_w = slewed` (a cap of zero) is better again at 32.02 kWh and is refused: it is the velocity form this module's docstring says `i_w=None` collapses to. TWO COMMITTED NUMBERS MOVED, DELIBERATELY, WITH THE REASON BESIDE THEM. SAFETY-13's released command settles at -800 W and -1200 W where release/1.0 settled at -1190 W and -2390 W, because there is less wound integrator to settle onto; AC 4's property - it stops at the frozen integrator, not the rail - is what is asserted and the second is now graded against `i_w` rather than a literal. And SAFETY-39's "the slew does not own the over-absorption" is now FALSE - INVERTED, on the independent first-order plant test_control.py writes itself: 1005/1109/1285/1330 W rising with a slower slew becomes 729/550/424/326 falling. Two plant models that share nothing agree on the sign. Evidence: `tools/replay_recorded_loop.py` plus the read-only capture it made (scenarios/loop-2026-09-02_2026-09-17). The "before" law is the shipped file with the block removed by a named substitution - never a transcription - and a missing anchor is a REFUSAL carrying "NOTHING HAS BEEN MEASURED". The instrument prints its own fidelity first: it reproduces 39.6 kWh of export where the install exported 29.4, i.e. it is ~35 % pessimistic about the loop's tracking, so only the delta is claimed. 30/30 suites green, including test_control.py's exhaustive i_w=None equivalence sweep against the transcribed release/1.0 law, untouched: the cap moves `i_w` and not `target`, and that sweep compares (target_w, sat_count, frozen, reason). Six law mutations, one instrument battery. L4 - the cap applied unconditionally, -92 B - was a SURVIVOR of all thirty files: it is bit-identical on the shipped configuration (0 of 256 246 ticks) and separable on 2050 of 257 400 swept states, all at `integrator_max_w` above `max_w`, which part 4 now drives. L5 and L6 are ZERO BYTES. AND TWO COMMENTS IN THIS CARD WERE INVENTED AND ARE CORRECTED IN PLACE. The one-sided spelling was justified by a two-sided form that would "drag a trailing integrator" - it does not, and the two agree on 205 920 of 205 920 swept states; and a "118 of 256 252 ticks" figure had been measured against a different pair. MUTATION.md gains habits 21 and 22 for both shapes. NOT DEPLOYED, NOT VERSIONED. The live install still runs release/1.0's law.

SAFETY-13: the bound came from the wrong half of a two-sided measurement
checks / unit (pull_request) Successful in 5m34s
NOTES.md 5.10 measured the 1.78 kW step BOTH ways - "Up: ~18 s from step to deadband. Down: ~23 s" (NOTES.md:1550). SAFETY-39 takes 18 correctly: its bound is a REFUSAL and the looser number refuses less. This branch reused PLANT_SETTLE_S for the opposite job - how long the plant may still be the EXPLANATION for a divergence - where the conservative half is the longer one. ceil(23/2) = 12, not 9, and being short there does not refuse anything, it accuses. The false positive is real and is measured here. One inverter, one compute(), one plant, no second writer anywhere in the harness: the command falls through zero while the pack is still coasting the old way, unasked_power() calls our own power "unasked", the counter reaches 9 while it is still coasting, and the law emits "freeze-released". At the plant's own measured 18 s/23 s shape, over 272 load-step pairs, the 9-cycle bound fires in 62 and the 12-cycle bound in 2. PLANT_SETTLE_DOWN_S = 23.0 is added beside PLANT_SETTLE_S = 18.0, because the plant's settling time is a PAIR and each bound has to say which half it means and why. SETTLE_CYCLES = ceil(PLANT_SETTLE_DOWN_S / LOOP_TICK_S) = 12. It is no longer the reciprocal of SLEW_RAIL_FRAC; that was a coincidence of both reading the same half, and test_control.py now asserts the inequality. _SAT_COUNT_CAP moves with it, 10 -> 13. config.yaml accepts saturation_cycles as int(1,10), so the whole accepted range is now strictly BELOW the bound and the degenerate configuration this branch used to document no longer exists - pinned against config.yaml's own schema line. Three shipped statements were falsified by that measurement and are rewritten, not renumbered - at 12 the residual is smaller, not zero: unasked_power()'s docstring said anything outside the interval "was put there by something other than this loop". It was our own power: eight cycles after a +1990 W command the command is 0 and the pack still reads +522.3 W. control.py said "SO THE BOUND BELONGS TO (b) AND ONLY TO (b)". It fired in case (a). DOCS.md told an operator "if you see freeze-released, look for the second writer" - on a single-inverter install, hunting something that does not exist. Replaced by a section that gives the innocent causes first (a large load or PV swing; a plant slower than the one measured, 8/320 scenarios at 23 s rising to 268/320 at 50 s) and the second writer only when the state STANDS. Round 1's own results are kept and re-graded, not weakened. The release/1.0 sweep had to widen to reach the new bound (3780 cases): 3267 bit-identical, 432 releases, 27 command changes - all still charge starts from prev_w == 0 - and 81 differing in the saturation counter alone, which nothing downstream can read. The card's case releases on the twelfth saturated cycle instead of the ninth and settles at the same -1190 W against the same frozen integrator. Also corrected, because they were claims and did not reproduce: the coverage table's "output freeze" row was 11, and the mutation form its own note describes gives 6 on this tree, 6 on the first SAFETY-13 commit and 2 on release/1.0; the detector row was left at 11 and is 15; the frozen = False footnote was left at 10 and is 13. And section 6 reported 107 625 as "released states" when it is the number of states SWEPT - 67 500 of them release, and both are counted now. Nothing here reached the inverter. 22/22 test files pass in goodwe-addon-ci, tree rsynced to a plain path, mounted :ro, python3 -B, __pycache__ purged and printed first (0 dirs / 0 .pyc; the worktree carries none).

SAFETY-13: the output freeze gets an exit, and only where it needs one
checks / unit (pull_request) Successful in 5m30s
While the loop is frozen the command's magnitude may fall but never rise. At prev_w == 0 there is no magnitude left to fall, so a charge cannot START. That refusal is deliberate and it is kept: the inverter reporting power we did not command means another writer is on the actuator, which is the §1.5 non-goal. What it did not have was an END - nothing cleared it but the other writer leaving. Reproduced on release/1.0 @ |

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.

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. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

SAFETY-04: record the coverage audit as a comment, with its invariant
The audit found a dead mechanism twice, both times a clamp standing in for the mechanism under test, so the technique has to survive this ticket. Not as a script: the only cheap way to automate it is to key on source lines, that goes stale silently, and a green audit that has quietly stopped testing anything is this ticket's own failure mode one level up. Automating it properly would mean decomposing compute() to make its statements separately addressable, which is a refactor of the most safety-critical function in the repo for the benefit of test tooling. So it goes in as a comment block next to the checks it describes, carrying the commit it was measured at, the thirteen figures, and the invariant with the teeth in it: every mechanism must be noticed by at least two checks when it is deleted, and adding a mechanism means re-running the audit. A comment cannot go stale-green, because it never claims to be running. Also recorded: fixtures must sit clear of every rail they are not testing, which is the rule both misses violated; and the `python -B` / clear-pycache discipline, with the reason (CPython invalidates on source mtime-in-seconds plus size, so a same-second same-size rewrite reuses stale bytecode) and the reason it casts no doubt on the figures (the error is one-directional, so every number is a lower bound). Figures are the lead's independent reproduction. I re-measured the one that differed: the detector is 11 for `saturated_now = False` and 10 for the weaker `frozen = False` form, so the table names the form. test_control.py stays at 55 checks, all passing.

SAFETY-04: stop the clamps standing in for the mechanisms under test
AC 3 - "integration freezes while saturated" - had no non-vacuous test. Deleting the integrator freeze outright failed 0 of 55 checks: the two checks that name it used a fixture at max_w 2000 with the integrator bound following it, so a wound value was truncated back to exactly 2000 and the assertion passed on the clamp instead. Fixture lifted to max_w 5000, clear of every rail. Deleting the freeze now fails 2. Then swept the whole function for the same pattern, one mechanism at a time: delete it, count which checks notice. It found a second instance - the OUTPUT clamp. `clamped to max_w` and `clamped to -max_w` were both satisfied by the integrator bound truncating first, so removing the output clamp failed only the reason-string check. Those two fixtures now set integrator_max_w above max_w so the mechanism they name is the binding one; the output clamp goes from 1 failure to 3. Every mechanism in compute() is now caught by a check that names it: freeze 2, integrator clamp 6, bound-follows-max_w 4, output clamp 3, slew 4, output freeze 2, deadband 5, quantise 2, detector 10, duration 2, counter reset 6, grid bias 3, None-seeding 6. No mechanism at zero. Method note: the audit disables bytecode caching. Rewriting control.py inside one second leaves a stale app/__pycache__ entry and silently under-reports - it under-reported one mutation as 2 failures where the true figure is 6. test_control.py stays at 55 checks, all passing.

SAFETY-04: exactly zero is its own case in the freeze tie-break
`min(moved, i_w) if i_w > 0 else max(moved, i_w)` files i_w == 0.0 under rising-only, so the first push toward charging from exactly zero was blocked permanently - the S-1 deadlock again, mirrored in sign. main.py resets i_w to exactly 0.0 on every stop and every reseed, so it is a normal state. Zero is now handled explicitly and both directions are allowed: nothing is wound, so "may not wind further" has no referent, and a first step from zero is bounded by the gain, the output clamp and the slew limit like any other. Measured before the fix, at i_w == 0.0 and frozen: 12 800 of 25 920 ticks held the integrator and 8 304 of those changed the emitted command, worst case abandoning a 2 kW charge into a 4 kW export. Note this is NOT the same as the reported symptom: at prev_w == 0 the command holds at 0 W either way, because the output freeze forbids starting a charge while saturated, and that rule is release/1.0's and unchanged. There is now a test asserting it deliberately. Tests. The durable part is a property rather than more points: over 13 041 frozen states the integrator may be held ONLY by a correction pushing it further from zero on the side it already sits, and any other hold fails. Both signs at exactly 0.0. Mirrors added everywhere the suite tested one direction of two - freeze wind/unwind while charging, i_w=-100, the export-direction runaway, the negative clamp and slew. DOCS: the cycles-vs-seconds deviation is now written down as a deviation - the "> 10 s" criterion is not met as literally written, a cycle is one CHANGED meter reading, and there is no guaranteed wall-clock window. test_control.py: 43 -> 55 checks, all passing.

SAFETY-04: revive the clamp reason, and compare reasons in the sweep
`want = i_w` after the integrator bound, so at the default limit == max_w the output clamp can never fire and `reason == "clamped"` had become unreachable. Observability only today - nothing gates on the string - but SAFETY-03 exists to alarm on exactly that engagement, so its hook was dead before it was built. The integrator bound now reports "i-clamped", and that is the signal SAFETY-03 must watch: it is the one that fires on a default install. "clamped" stays reachable for a configuration that lets the integrator run above the rail, where both fire and the output clamp - which describes the value actually emitted - is the one reported. Two names because the two events want different alarms: the loop winding, versus a command that came out over the rating. The real fix is the second half. The equivalence sweep compared (target_w, sat_count), which is how a dead reason survived 3024 cases. It now compares (target_w, sat_count, frozen, reason) and it catches this defect: dropping the emit turns it red. Deliberate rename aliased explicitly, so any OTHER reason divergence still fails. Result of adding reason to the tuple: 105 of 3024 cases differ, and every one of them is the i-clamped/clamped rename. Zero value divergences, `frozen` included. Nothing else surfaced. test_control.py: 41 -> 43 checks, all passing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Du77usMj8XNKNFZGmUiWDa |

SAFETY-04 review fixes: the freeze deadlocked, the bound was too loose
S-1. The frozen branch admitted a correction only if it shrank |i_w|. That is unsatisfiable for BOTH signs of error whenever |correction| > 2*|i_w|, i.e. whenever the integrator is near zero, so the loop stopped moving and the freeze could never clear - it clears when the inverter tracks, and not tracking is what saturation means. Measured: 0 W held into a 2 kW import indefinitely, where release/1.0 recovers on the next cycle. Re-encoded as the same asymmetric rule the output freeze has always used: may not wind further in the direction it is already pushing, may fall, cross zero or reverse. Same interpretation, an encoding that cannot deadlock. S-2. integrator_max_w defaulted to 1.5x max_w, which ADDED windup: in release/1.0 the accumulator was the post-clamp command and could never pass the rail. Default is now "follow max_w" (config 0 = unset). Measured on the 4000 W load-drop sim, first cycle after the drop: 1000 W at the new default, 1800 W at 3000. DOCS row inverted - the useful direction is below max_w, and the 14 768 W anecdote is a vendor controller, not evidence about this code. S-3. The claim that i_w=None preserved release/1.0 exactly was false, because the S-1 gate ran regardless of seeding. It is true again, and now asserted rather than asserted-about: 3024-case exhaustive comparison against a transcription of the old law, over both freeze states, both signs and either side of the deadband. Added the carried-i_w convergence/overshoot sim that the shipped configuration was missing. S-4. Cycles are distinct meter values, not seconds: cycle() runs only when the meter reading changes, so the window has no wall-clock bound. Comment and DOCS corrected; the stall is detection latency, not a windup hazard, because the same condition stalls the whole loop. test_control.py: 33 -> 41 checks, all passing.

SAFETY-04: clamp the integrator, not only the output
The loop was in velocity form: the accumulator WAS the commanded power, so "clamp the integrator" and "clamp the output" were the same line of code and could not be set apart. This makes the accumulator an explicit carried value (`i_w`), bounds it with its own `integrator_max_w`, and keeps the output clamp where it was. Killing either mechanism now still leaves the other holding - which is the point of the ticket, and what the new regression test asserts. Freeze semantics: while saturated the integrator may unwind but not wind further. A strict freeze would strand the command at whatever it reached, because the condition that releases it is the inverter tracking again, and not tracking is exactly what saturation means. The integrator is re-seeded from the arbiter's actual output whenever the loop did not get what it asked for, so entering any failsafe (all of which resolve to 0 W) zeroes it, and the first cycle after release does not dump the stale period as power. test_control.py: 24 -> 33 checks, all passing.

Rest the meter just below zero, not at zero
The deadband is a one-way ratchet: any resting point inside it holds indefinitely. Import and export are separate registers on the meter, so a loop resting at +14 W bills 0.34 kWh/day while behaving perfectly. target_grid_w (default -10 W) moves that residue onto the export register. Worst billed rest point drops from 15 W to under 5 W. Behaviour is unchanged at target_grid_w: 0. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Precedence arbiter: one rule instead of an if/else ladder
Two controllers writing one actuator is the failure this system exists to
avoid. "Exactly one writer" was true, but only as a convention held up by
careful reading - which does not survive an EV charger and a heat pump wanting
the same battery.
Strategies now return claims and arbiter.py resolves them:
highest-priority `set` wins (none at all means 0 W), then every `limit` whose
priority is >= that set's applies, most restrictive first; contradictory
limits command 0 W and are flagged as the bug they are.
The second clause is the whole point. "Money outranks maintenance" used to be a
hand-written exception inside a Jinja template; it is now a consequence of the
priorities - the charge-only limit binds the loop but cannot bind a
higher-priority peak claim.
Also: maintenance shaping moved out of control.py, which is a controller again
and not a policy engine; the loop now tracks the arbiter's actual output rather
than its own last wish, so it does not jump when it regains control; and every
decision explains itself ("loop -> 0 W, limited by maintenance(charge-only)")
in the UI and the log.
19 new assertions in test_arbiter.py, each one a precedence question someone
will eventually ask in the field. Deployed to the reference site as 0.2.0 and
holding grid within a few watts of zero.

Packaged as a Home Assistant add-on, with a field guide
Turns the reference RS485 controller into something a technician can install at a client site: a typed config form instead of YAML, an ingress UI that names misconfiguration in words, and persistent state that cannot be broken by a timezone. Why an add-on rather than YAML packages or blueprints: - Blueprints cannot create helpers, and the maintenance cycle is a state machine whose phase and completion date must survive restarts. - YAML packages need filesystem access, a configuration.yaml edit and a restart - none of which belong in a client install. - Add-ons authenticate with SUPERVISOR_TOKEN, so there is no long-lived token to generate, store or leak on someone else's machine. - Requires HA OS/Supervised. Container and Core installs cannot run add-ons at all, which is a market decision, not an oversight. The control law and the maintenance machine are pure functions with no Home Assistant imports, and both ship with runnable checks (22 and 22 assertions). Every assertion corresponds to a rule whose absence caused an observed failure on hardware - the saturation duration term, the clamp-before-slew ordering, the deadband, the sign convention. One behaviour deliberately differs from the implementation it replaces: when its inputs go missing this commands 0 W rather than replaying the last setpoint. The reference version kept replaying, which the hardware watchdog cannot catch - from the ESP32's side, Home Assistant is still talking to it. Includes the ESPHome firmware (now parameterised: node name, inverter rating, watchdog timeout) and the optional RS485 e-stop. FIELD-GUIDE.md carries the commissioning gates, all judged on the wire rather than on how Home Assistant looks, plus the written statement a site without an e-stop needs signed.
