kb_changelog

List the coffees registered for the account, with status filter. Each coffee carries its bags[] (every purchase, with its own freshness and grams left) and current_bag_id; the row's top-level roast_date, state, grams_remaining and age fields are the current bag's. The `id` on each row is the number this account knows that coffee by, counting from 1 — safe to show, and what other tools expect back; bag ids are a separate series.

list_beans

List machines registered for the account, with status filter. The `id` on each row is the number this account knows that record by, counting from 1 — safe to show, and what other tools expect back. Each row carries its maintenance block, researched per model: every task with its class, due state, what the maker forbids, and the guide to follow. `settings` lists the selectors its model has and where each stands (null: unknown model, or none).

list_machines

List grinders registered for the account, with status filter. The `id` on each row is the number this account knows that record by, counting from 1 — safe to show, and what other tools expect back. Each row carries its maintenance block: every task with its class (S schedule, H habit, Y symptom, A the machine signals it, T technician, N never, U unstated, E event), due state, and the guide to follow.

list_grinders

List recipes (all or filtered by equipment and status). The `id` on each row is the number this account knows that record by, counting from 1 — safe to show, and what other tools expect back.

list_recipes

What maintenance is due across the user's current grinders and machines, most urgent first — for "is anything due?". Only tasks with an interval compete: a task the machine counts and signals itself, one done by habit or when a symptom shows, and one the maker advises against never appear. Each item says how far along it is (ratio, done of every, on which basis), whether it is coming up (soon), and whether the interval is the user's, the maker's or ShotPulled's default.

list_maintenance_due

List registered scales for the account. The `id` on each row is the number this account knows that record by, counting from 1 — safe to show, and what other tools expect back.

list_scales

List shot history with support for pagination and filtering. Every shot carries a derived taste_pending flag (1 = logged with no sensory tags, no rating, and no tasted flip — the tasting is still owed and can be backfilled with update_shot).

list_shots

List registered waters for the account. The `id` on each row is the number this account knows that record by, counting from 1 — safe to show, and what other tools expect back.

list_waters

Lock a successful shot as the reference dialing recipe for this equipment profile. It overwrites the recipe already locked for the same coffee, grinder, machine, program and drink intent, which keeps its recipe_id.

lock_recipe

Log a recommended dialing change to allow contradiction/oscillation checking (G2).

log_recommendation

Log an espresso or alternative shot/brew attempt. Uses the active context (bean/grinder/machine/program) unless overridden via bean_id/grinder_id/machine_id/program_id — ALWAYS pass bean_id explicitly when the user names a specific coffee, so the shot cannot land on the wrong bag. Backdate with pulled_at when the shot happened earlier. When the user reports taste (bitter, sour, harsh, hollow…), include matching sensory_tags — the diagnosis engine reads tags and metrics, not free-text flavor_notes. When the user tasted the shot and reports it as GOOD/clean (no defects), pass tasted=1 with no sensory_tags — otherwise a tag-less, rating-less shot is filed taste-pending as if never tasted.

log_shot

Log a cleaning or maintenance job against a piece of equipment. A task that takes the thing apart opens a calibration epoch, and every recipe locked before it is read through that epoch's offset — so record the offset here if you counted the clicks while reassembling, which is the one moment anybody actually knows it. Any task in the maintenance vocabulary can be logged against a grinder or machine it belongs to — including one the maker advises against, because the log records what was done. Read each piece of equipment's tasks, their intervals and their due state from list_grinders and list_machines.

log_maintenance

Fold one coffee into another when the same coffee was registered twice. Every bag, shot, recipe and recommendation of from_bean_id moves to into_bean_id; the active coffee follows if it was the one merged away; origins move only if the target has none. Where both hold a locked recipe for the same grinder, machine, program and drink, the newer lock wins and the older is deleted. The source coffee is archived, never deleted. Irreversible — confirm both numbers with the user first (list_beans shows them).

merge_beans

Sandbox-only diagnosis, writes nothing (no verdict, no recommendation-trail entry). Two modes: pass shot_id to dry-run a LOGGED shot (optionally overriding its sensory_tags — the "what would this read as?" preview; the shot's own bean and its age at pulled_at are used), or pass the full metric set (bean_id, grinder_id, machine_id, grind_label, dose_g, yield_g, time_s, source) for a hypothetical shot. Identical output shape to diagnose_shot, including bean_context.

diagnose_preview

Register another bag of a coffee that is already in list_beans — the same roaster's product, bought again. It keeps the coffee's recipes, notes and history; only the purchase facts (roast date, weight, price, state) are new. Does not change the active coffee. Returns a bag_id: bag numbers are their own series, separate from bean numbers. For a coffee that is not in list_beans yet, call register_coffee instead.

register_bag

Register a coffee that is NOT yet in list_beans, together with its first bag. It does not switch a coffee in use: it becomes active only when no coffee is in use (none active, or the active one archived or with every bag finished); otherwise call set_active with its bean_id when the user starts brewing it. The `active` field of the reply says which. The coffee is the roaster's product (roaster, origins, variety, process, roast level, roasting type, cupping score, aromatics, roaster notes, rest window); the bag is this purchase (roast date, weight, price, state). For another bag of a coffee already on file call register_bag instead — it keeps the recipes and notes. Returns bean_id and the first bag's bag_id.

register_coffee

Register a manual or electric grinder with its dial settings scheme. It becomes the active grinder only when no grinder is in use (none active, or the active one archived); otherwise call set_active with its grinder_id to switch to it. The `active` field of the reply says which.

register_grinder

Register a programmed shot button on a machine. A program cuts the shot off either by weight (program_type "volumetric", set target_volume_g) or by time (program_type "timed", set target_time_s). One machine can have a mix of both. A program_number the machine already has is overwritten with these settings; shots logged on it keep pointing at it.

register_program

Register a brewing scale — the instrument that weighs the dose and the yield.

register_scale

Register a custom or commercial water formulation.

register_water

Register an espresso or alternative preparation machine. It becomes the active machine only when no machine is in use (none active, or the active one archived); otherwise call set_active with its machine_id to switch to it. The `active` field of the reply says which.

register_machine

Set the user's own schedule for one maintenance task on one grinder or machine: their own interval, switching it off, or muting the reminder until a date. Only the keys you send in fields change; send every: null to go back to the maker's guidance and muted_until: null to unmute. Use it when the user states how often they do a task or asks to be left alone about one — never to invent an interval. The task's class, interval and due state are read back from list_grinders and list_machines.

set_maintenance_schedule

Switch the active bean, grinder or machine for this account. The numbers come from list_beans, list_grinders and list_machines. Registering a coffee, grinder or machine makes it active only when nothing of that kind is in use (the `active` field of the reply says which), so call this to start using something new as well as to switch back.

set_active

Record how far a maintenance job moved the reference, on an entry that opened a calibration epoch. Takes an ENTRY, not a piece of equipment: the offset belongs to the event that caused it, which is what lets several of them compose for a recipe locked before all of them. Zero is a legitimate measurement and means "measured, and it had not moved" — omit offset_value entirely to clear it back to unmeasured.

set_maintenance_offset

Set the current grinder collar position. source="measured" resets verification freshness. It replaces the stored position; no history of earlier positions is kept.

set_grinder_position

Retrieve the single next experiment step from the reasoning engine.

suggest_next_step

Change bag-level facts on one bag of a coffee: open, seal, freeze, thaw or finish it, correct its roast date, weight, grams left or price. Bag numbers come from the bags[] on list_beans (or current_bag_id). For the coffee itself — roaster, origin, roast level, rest window, notes — use update_bean.

update_bag

Update a coffee's own fields (roaster, origins, roast level, rest window, notes, rating…). Bag-shaped fields sent here (state, roast_date, bag_weight_g, grams_remaining, cost…) land on the coffee's CURRENT bag — use update_bag when it has more than one. Changing dial_category changes what the engine advises (G5, C10), so say why in the optional note.

update_bean

Correct a registered grinder — its name, burrs, collar scheme, nominal step, layout, range or notes. Only the keys you send in fields change; send null to clear an optional field (an empty string also clears a text field, but not a number or a closed list). Required fields can be changed but not cleared. fields may be omitted when only reason is sent. setting_scheme, nominal_step and components_spec describe the collar every recorded grind label is read through: call with dry_run first to see which recorded settings would read as a different position, and tell the user before saving. Saving records the change in the grinder's maintenance history; when a locked recipe's setting moves it also opens an unmeasured calibration epoch (set_maintenance_offset resolves it). The collar's current setting is marked assumed when it reads differently, or cleared when the new collar cannot read it, and measured offsets are converted when a click changes worth. Changing direction_convention is a correction — it moves no number, but every finer/coarser said about this grinder was the wrong way round.

update_grinder

Correct a registered machine — its name, control type, prep type and style, basket, boiler, accessories or notes — or record where its selectors stand (settings). Only the keys you send in fields change; send null to clear an optional field (an empty string also clears a text field, but not a number or a closed list). Required fields can be changed but not cleared. fields may be omitted when only reason is sent. prep_style decides whether shots on this machine are diagnosed at all: only "espresso" is. Programs are edited with register_program, the built-in grinder link is not editable here, and archiving is set_equipment_archived.

update_machine

Correct a registered scale — its type, resolution, capacity, capabilities, build or notes. Only the keys you send in fields change; send null to clear an optional field (an empty string also clears a text field, but not a number or a closed list). Required fields can be changed but not cleared. fields may be omitted when only reason is sent. The three capabilities are 1, 0, or null for "the maker never said"; leave one out rather than sending 0 when nobody knows.

update_scale

Correct fields on an already-logged shot in place — no need to delete and re-log. Use for fixing a wrong dose/yield/time or grind label, re-filing a shot onto the right bean (bean_id), backfilling rating/tasting notes, or fixing the timestamp (pulled_at). Changing grind_label re-derives the numeric grind position from the shot's grinder; changing yield/time/dose/tds keeps flow rate and extraction yield consistent automatically.

update_shot

Correct a registered water — its name, type, mineral figures or notes. Only the keys you send in fields change; send null to clear an optional field (an empty string also clears a text field, but not a number or a closed list). Required fields can be changed but not cleared. fields may be omitted when only reason is sent.

update_water
