v1.1.0

[1.1.0] - 2026-05-06

Design templates rebuild + automatic Pro+ calibration on every slice
tool + safer pre-print validation gate + a self-service tier diagnostic.

Added

• check_my_tier MCP tool — answers "what plan am I on, and why" for
  agents handling user questions about tier / subscription / paywall
  confusion. Walks the live tier-resolution chain (env var → license
  file → OAuth session → cached entitlement → free fallback) and
  returns a plain-English summary the agent can paste straight to the
  user. Free-tier safe — no license needed to call.
• First-time calibration overlay notice — the first time Kiln
  applies your slicer calibration to a slice (Pro tier), the response
  carries a first_time_notice block that the agent can surface to
  the user ("Kiln just used your OrcaSlicer profile…"). After that,
  silent overlay with the audit trail in every slice response.
  Removable marker at ~/.kiln/calibration_overlay_first_use.seen if
  you want to re-trigger the notice.
• Pro+ continuous calibration learning — when Kiln Pro is
  installed, per-printer offsets refine from every observation (not
  just one-time profile imports). Freshness tracking surfaces when
  your printer drifts; full provenance answers "why is this dimension
  what it is?".
• tablet_stand template — dedicated for tablets / iPads, with
  wider base depth, taller back panel, and slot sized for keyboard
  cases. Phone stands stay focused on phones.
• Pre-print validation gate runs by default — slice_and_print,
  run_quick_print, and run_reslice_and_print now validate the
  mesh against printer + material constraints before slicing.
• Per-machine calibration overlay applied uniformly — Pro+
  calibration now applies to slice_and_print (previously only
  slice_model and reslice_with_overrides).
• kiln events tail / kiln events summary — read-only CLI
  access to the local event log.
• Craftcloud order safety gates — fulfillment orders now require
  an explicit preview-confirmation token AND a shipping-address
  confirmation token before placing. Two new endpoints
  (POST /api/fulfillment/preview-confirm,
  POST /api/fulfillment/shipping-confirm) issue the tokens after
  the user has actually seen the rendered preview and reviewed the
  shipping address. Prevents "agent placed an order I didn't
  expect," surprise shipping mismatches, and stale-quote charges.
• Local shipping profiles store — named shipping addresses now
  persist locally at ~/.kiln/shipping_profiles.json (override via
  KILN_SHIPPING_PROFILES_PATH) and can be referenced by name when
  issuing a shipping-confirm token. No more re-entering the same
  address every time you order a part for the same workshop or
  customer.
• Food-safety material overlays — material-recommendation,
  slice, and food-contact tool paths now consult a structured
  food-safety catalog. PETG / PETG-HF surface as food-safe; PLA
  returns a conditional verdict with constraints (water-only,
  hand-wash, replace 6-12 months); ABS, TPU, ASA, and CF blends
  hard-refuse with MATERIAL_NOT_FOOD_SAFE. Affects
  generate_pet_bowl, material recommendations, and slice metadata.
• Anonymous unique-device counting — heartbeat telemetry
  (already on in v1.0) now includes a one-way-hashed device
  fingerprint so we can count unique installs without identifying
  anyone. No reversal possible; no PII collected.
• Free-tier recommend_settings calibration overlay — free
  users now get per-printer calibration data folded into setting
  recommendations when a calibrated profile is present (Pro+ writes,
  free reads). Smaller-than-Pro continuous-learning, but real.

Changed

• 3 design-template MCP tools renamed — find_design_templates,
  list_design_templates_catalog, get_design_template_info. The
  prior _design_patterns_ names are removed in this release (see
  Removed below).
• Design template count: 17 → 18 — dropped 3 (cable management
  clip schema break, GoPro mount single-vendor, wall mount bracket
  folded into cantilever bracket), then split phone stand into
  phone_stand + tablet_stand.
• design_patterns.json → design_templates.json — file name
  matches the user-facing concept. Old Python imports
  (DesignPattern, pattern_id, get_design_pattern, etc.) are
  removed in this release (see Removed below).
• WHITEPAPER + LITEPAPER — refreshed to match current capability
  • count.
• Site nav — Install hoisted to the top of the Product menu;
  install copy refreshed.

Fixed

• Free-tier safety-floor fallback — when the engineering overlay
  isn't loaded, design intelligence returns conservative safety-floor
  recommendations instead of an error.
• PTFE temperature clamp now actually fires — the safety guard
  capping PTFE-lined hotends at 240°C had a silent failure path
  (PrinterIntel dataclass treated as a dict) that meant Ender 3,
  Ender 5, and any other PTFE-lined hotend was getting the profile's
  raw 260°C ceiling instead of the PTFE-safe 240°C. Now clamps
  correctly; set KILN_OVERRIDE_PTFE_LIMIT=1 to disable for
  user-installed all-metal conversions.
• Decoration engine fixes — face detection, deboss math,
  decoration hierarchy, and fit calculations all hardened in
  this release. Affects users who hit edge-case decoration
  bugs in v1.0.
• Documentation counts refreshed across README, white paper,
  litepaper, FAQ, and the marketing site.

Removed

• MCP tools find_design_patterns, list_design_patterns_catalog,
  get_design_pattern_info — replaced by the _design_templates_
  variants in this release. No back-compat aliases.
• Python imports DesignPattern, pattern_id, kb.patterns,
  get_design_pattern, list_design_patterns,
  find_patterns_for_use_case — all renamed to DesignTemplate,
  template_id, kb.templates, get_design_template,
  list_design_templates, find_templates_for_use_case.
