Alongside the dated log files, ServerLogTask/SudLogTask now also write
(and overwrite) a fixed-name copy on every write() - logs/log_latest.json
and logs/log_latest_sud.json - so a dashboard/tail-style consumer can
point at one unchanging path instead of tracking the current run's
timestamped filename.
Also switches SudLogTask's own dated/latest filenames from .log to .json,
matching what they've always actually contained. This incidentally fixes
utils/analyze_log.py's two-argument CLI form, which already assumed a
.json extension for sud logs.

sim_warp_factor was scaling DT_TASK unconditionally, including against real
hardware, and was leaking into recorded sample timestamps via wall-clock
time - both violate its intended meaning (a reciprocal scale on task wait
time only). Clamp it to 1.0 whenever Heater.type isn't "sim", and track
elapsed time via tick-counted accumulators (Sud.elapsed for SudLogTask, a
matching one for ServerLogTask) instead of time.monotonic().
Sud/server logs now also carry HeaterPowers, the effective SimWarpFactor,
the raw Doc, a correct Name, and ForecastAnchors (one entry per real
_reanchor_forecast() trigger) - enough for utils/analyze_log.py to rebuild
a SudForecastEstimator and replay the exact same splice-per-transition
forecast correction offline that a live client sees, replacing the old
(always-dead) forecast_*.json sidecar lookup.
Two bugs found and fixed along the way:
- ServerLogTask's periodic wall-clock checkpoint had no way to know a
SudLogTask run had just ended, so it would immediately re-write the
just-completed log with PlantParams/ForecastAnchors cleared back to
empty. Gated the checkpoint on _should_sample().
- _reanchor_forecast() truncated the old forecast against real elapsed
time, which can end up numerically less than the old forecast's own
(very wrong) speculative timestamps once a WAIT_USER confirmation runs
long - leaving a "ghost" segment instead of a clean cut. Truncate
against forecast_step_starts[index] instead, which lives in the same
coordinate space as the forecast being cut.

- Rename "State replay on connect" to "State is server-only; GUIs only
reflect it" and expand it with the core design principle: neither GUI
client ever maintains its own model of server state — controls update
only on server push, never speculatively on user input. Multi-client
sync, stale-overwrite safety, and reconnect correctness all follow from
this single rule.
- Update TC-enable description: HeaterTask now owns the TC's enabled
switch via the closed_loop flag; SudTask no longer touches it.
- Add "Heater control modes" subsection describing Closed-loop/Open-loop,
the enable/disable rules per mode and sud state, the auto-reset on play,
and the schedule parameter restore on resume.

checkbox, header countdown timers, and the always-reflect-server-values

A new HTML/CSS/JS client, added next to client/brewpi_gui.py rather
than replacing it, speaking the exact same WebSocket pub/sub protocol
- no server-side protocol changes needed. server/brewpi.py gains a
--http-port (default 8080) stdlib http.server.ThreadingHTTPServer,
in its own daemon thread and deliberately decoupled from the existing
asyncio WebSocket server, serving web/ statically.
v1 covers the Manual tab (direct heater/stirrer/controller control)
and the new Progress tab - the two most actionable surfaces, neither
needing a charting library. web/app.js ports the relevant logic from
brewpi_gui.py directly: components/sud.py's _build_step()/
_merge_defaults() for resolving the raw schedule doc, and the
StepPlate/_update_step_plates()/update_status_step_label() logic
behind the Progress tab and status line.
Deliberately deferred rather than stubbed (see web/TODO.md for the
full parity backlog against the Qt GUI): Sud control actions (Start/
Pause/Stop/Confirm), the Automatic tab's forecast plot and the Plot
tab's live strip charts, Sud file management, and auth (matching the
WebSocket server's own existing lack of it).
No new Python dependencies - functools/threading/http.server are all
stdlib.

heater_name/sensor_name/plant_name were three independent config keys,
each picked via its own factory - in practice sim and real hardware
are never actually mixed and matched, so this could (nonsensically)
disagree, e.g. a real heater paired with a simulated sensor.
Add PlantFactory (components/plant/plant_factory.py): plant_name alone
now builds the whole rig together. "sim" gets HeaterSim/Pot (the
modeled plant, as before)/TempSensorSim. Anything else gets
HeaterHendi/PotReal/TempSensor_max31865 - PotReal is a new, deliberately
unmodeled Pot for the real, physical kettle (components/plant/pot_real.py):
the real temperature comes straight from the real sensor, not from a
model, so it just accepts and ignores set_plant_params()/
set_ambient_temperature()/initial() and reports no temperature of its
own, satisfying PotTask/SudTask's interface with nothing to actually
simulate.
heater_name/sensor_name are gone from config.json.templ; server/brewpi.py
delegates to HeaterFactory/TempSensorFactory lazily from inside
PlantFactory, same as before, so real hardware's spidev/pyserial deps
still aren't needed just to import the module.
Documents the recent SudTask.send_forecast()/recv() changes (anchored at
get_theta_ist_set(), re-anchored on every fresh Start) and the two
spurious-divergence fixes: client/brewpi_gui.py's forecast_history t=0
seeding, and the hardcoded last_theta_ist=20 bug in both TempController
variants.

config.json.templ's component names already default to "sim" for every

server/brewpi.py no longer pre-configures the real Pot's or Smith's model's
plant params at startup - there's no longer any generic baseline at all,
since the only source of truth is now a loaded Sud's own doc (applied via
tasks/sud.py's SudTask.apply_plant_params(), on Load and on every step).
Ambient temperature and PID gains stay configured at startup, since
they're independent of any Sud (global setting / hardware tuning, not
doc-derived).
Add Pot.is_configured() (already existed)/TempControllerBase.is_configured()/
TempController(Smith).is_configured(), and have tasks/pot.py's PotTask and
tasks/tempctrl.py's TcTask skip process() while not yet configured instead
of letting it raise - so plant and temp control are genuinely inert (not
crashing) until a Sud is loaded. "Normal" has no plant-model dependency,
so it stays active regardless.
Also refreshes README.md: removes stale tracer.py/.mat references (already
removed in an earlier commit), documents SudLogTask's JSON logs, the doc's
L/Td fields, and this inert-until-loaded behavior.

_continue_forecast_after_confirm()'s bridge was repeating forecast_theta[-1]
to cover the real-world wait, but that's whatever value the simulation
happened to log the instant WAIT_USER tripped - often still mid-ramp, not the
step's actual hold target. The real controller stays enabled and actively
holding throughout WAIT_USER, so capture its setpoint (tc.get_theta_soll_set())
in recv() before calling Sud.confirm() - confirming synchronously pushes the
next step's own target onto it - and use that to fill the gap instead.

dead, so the GUI's forecast plot only ever showed the first segment on Load.

WsServerMultiUser.global_state persists every message ever broadcast
and replays the full accumulated state to any client that subscribes
- by design, so a client connecting fresh or reconnecting mid-run
always gets the same complete picture (see README's new "State replay
on connect" section). That mechanism has no concept of "transient":
the {'Sud': {'Error': ...}} added for Load-rejection got treated as
durable state just like everything else, so any client connecting
after the fact - even one that never touched Load - got the stale
error replayed on connect. Confirmed live before this fix.
tasks/sud.py: send {'Sud': {'Error': None}} immediately after the
error itself, clearing it back to neutral in global_state.
client/brewpi_gui.py: on_sud_changed() treats a falsy Error as a
no-op instead of popping an empty dialog.
README.md: documents the underlying principle (client state replay
on connect, and the corollary that one-shot events need explicit
clearing) under a new Architecture subsection, and refreshes the Sud
channel/forecast sections to match this session's other changes
(Elapsed-based dynamic forecast anchoring instead of wall-clock time
times the nominal warp factor, Load's Error reply).

Previously, whether a schedule step ramped at all was decided purely by
the presence of a 'ramp' key (components/sud.py's _advance()) - a
hold-only step jumped straight into its hold countdown, assuming the
plant was already at temperature. Now every step ramps toward
'temperature' first, for as long as the controller's own gap-tracking
FSM (TempControllerBase, already distinguishing HEAT/COOL/HOLD) says
the gap actually warrants it - via the new is_holding() (on APid and
TempControllerBase), which replaces a separate, redundant
TEMP_REACHED_TOLERANCE constant duplicated across tasks/sud.py,
components/sud_forecast.py, and scripts/demos/sud/demo_sud.py.
set_theta_soll() now recomputes the FSM eagerly so is_holding() can't
read stale HOLD for a tick after a much-further-away target is pushed.
components/sud.py's _build_step() always synthesizes a 'ramp' block
from default.step.ramp (so 'rate' is always available), but leaves
'temperature' undefaulted - every real sude/*.json's
default.step.temperature is inert template filler, and defaulting it
would send hold-only steps chasing 0 degrees. SudTask/
SudForecastEstimator/the demo only push a new theta_soll/heatrate_soll
when a step actually specifies its own temperature; otherwise the
controller keeps whatever the previous step left running.
Also fixes a related crash this surfaced: SudTask.remaining_schedule()'s
synthetic mid-hold step dropped 'ramp' to signal "don't re-ramp" - now
that every step always carries a 'ramp' dict, dropping it left 'rate'
missing the moment the synthetic step was re-resolved by
SudForecastEstimator. Drops 'temperature' instead, which is what
actually signals "no new target" under the new model.

- Architecture diagram: add client/user_config.py and
components/sud_forecast.py; note the pid/ controllers' 4-state FSM
(IDLE/HEAT/HOLD/COOL) and master enabled switch; expand the GUI
client's description (ambient temp, controller enable, pot reset,
Sud New/Load/Save/Start/Pause/Stop, forecast plot).
- Mash schedules: document Start's restart-from-finished behavior,
Pause's freeze-and-resume semantics, and the temperature
controller's enabled lifecycle (SudTask owns it during a run, off by
default otherwise, GUI checkbox for manual mode).
- Fix sude/'s "heat"/"hold" wording to the actual "ramp"/"hold" keys;
add matplotlib (demos-only) to the server requirements list.
- Logging & analysis: mention the text log alongside the .mat traces.
Documents why a brew commonly takes ~250-270 min against a ~160 min
static estimate: the PID cascade needs real time to spin up and settle
within the tight 0.2°C "reached" tolerance, a roughly per-step-constant
lag that accumulates across every ramp/hold transition. Found and
confirmed by a live measured run on the real server.
Pure rename (brewpi.py, brewpi.sh, requirements.txt, __init__.py) plus
the README's path references - no code changes. "server/" describes
the directory's role rather than duplicating the project name already
in brewpi.py itself.
Several sude/*.json schedules can exist on disk; only one runs at a
time, chosen by a client Load. Sud no longer takes a path at all - it
starts empty (EMPTY_SUD) and the server config no longer names a
specific schedule file, removing the implicit link to sud_0010.json
in particular. Reading/writing sude/*.json is now entirely the
client's job (e.g. the GUI's Load/Save file dialogs); the server's Sud
only ever holds whatever was last Load()ed, in memory, until replaced
or the server restarts.
Updates demo_sud.py/demo_sud_save_load.py to construct an empty Sud()
and load() a schedule explicitly, matching the new constructor.
A step's target temperature applies to the whole step (it's what a
ramp ramps to and what a hold then holds at), not just its ramp phase
- promote it from a nested "ramp": {"temp": ...} to a step-level
"temperature" field, defaulted like descr/grain_mass/etc. Updates all
consumers (Sud._build_step, SudTask, the GUI's forecast estimator,
demo_sud.py) and migrates sude/sud_0010.json and the README.
A step can now carry both 'ramp' and 'hold': it ramps to the target
temp, then holds there for the given duration, instead of needing two
separate schedule entries. Sud.temp_reached() switches such a step
from its ramp phase into its hold phase in place (re-firing the
step-changed callback so SudTask/demo_sud re-apply the hold's stirrer
settings); user_wait_for_continue still applies once the whole step -
both phases - is done.
Merges sud_0010.json's three ramp/hold pairs into combined steps.
Reverts 19dc7a9 ("Fix Sud hold duration units: seconds, not minutes")
per explicit instruction - duration is minutes again. Re-adds the
*60.0 conversion in Sud._advance() (hold_remaining is ticked in
simulated seconds), the matching conversion in the forecast plot's
_estimate_course(), and flips the README wording back.
grain_mass and water_mass now live on each step (defaulted from
default.step) instead of being fixed for the whole brew, since both
change over a mash (malt going in, water boiling off).
Sud.derive_plant_params() takes them as arguments so it can be
recomputed per step; the demo re-applies the resulting M/C to both the
real plant and the controller's Smith-predictor model on every step
change via the new Pot.set_thermal_params()/
TempController.set_model_params().

sude/sud_0010.json moved from a list of combined ramp+hold+wait
"Rasten" with global stirrer constants to a flat "schedule" list of
explicit {"type": "heat"|"hold", ...} steps, each carrying its own
stirrer_speed/stirrer_time_on/stirrer_time_off and an optional
user_wait_for_continue (+ user_message).
- components/sud.py: Sud now tracks the current `step` instead of
`rast`; "heat" steps enter RAMPING (advanced externally via
temp_reached()), "hold" steps enter HOLDING and count down
`duration` minutes (0 if omitted). Either step type can pause in
WAIT_USER via user_wait_for_continue, surfaced through the new
user_message attribute.
- tasks/sud.py: SudTask only pushes theta_soll/heatrate_soll on
"heat" steps, converts each step's stirrer_time_on/off into a
duty_cycle/cycle_time on every step change (replacing the old
state-based RAMPING/HOLDING stirrer switching), and broadcasts
user_message changes. Stirring is now fully schedule-driven instead
of implicitly stopped on WAIT_USER/DONE (DONE still stops it, since
there's no step left to read settings from).
- scripts/demos/sud/demo_sud.py: mirrors the same step-driven wiring.
- README's Mash schedules section rewritten for the new schema.

brewpi.py had a dead -m/--model CLI arg and sude/*.json schedules were
pure data with no code to drive them, despite the README documenting
them as if they were already wired up.
Add components/sud.py's Sud, which loads a sude/*.json schedule and
steps through its Rasten (ramp -> hold -> optional wait-for-user ->
next rest), and tasks/sud.py's SudTask, which drives the temperature
controller's theta_soll/heatrate_soll from the current rest and
switches the stirrer between continuous (ramping) and intermittent
(holding, via stirrSpeedRast/stirrDutyRast/stirrCycleTime) operation.
Exposes progress on a new "Sud" WebSocket channel and accepts
Start/Confirm commands. Enabled via a new optional top-level "sud"
config key (see config.json.templ/.sim).
"Reached target" is detected via abs(theta_ist - theta_soll_set) <
tolerance rather than tc.state == HOLD, since the latter can still
read HOLD left over from the previous rest for one tick after a new
target is pushed (tc.state only updates on the controller's own,
independently-scheduled process() tick).
