+# Aurélio Embroidery — Agent Guide
+
+The embroidery subsystem of the Portugal Futurista platform. This repo holds the
+universal vendor bridge, MCP server, IDE plugins, and all knowledge needed to
+connect any embroidery machine to the Aurélio fleet.
+
+## Repository layout
+
+| Path | What | Language/Toolchain |
+|------|------|-------------------|
+| `README.md` | Vision, philosophy, roadmap | — |
+| `AGENTS.md` | This file — agent instructions | — |
+| `vendor-registry/` | Machine vendor database (formats, connectivity, hacks) | YAML |
+| `mcp/` | Aurélio Embroidery MCP server | Python, FastMCP |
+| `plugins/desktop/` | Aurélio Desktop IDE plugin | TypeScript |
+| `plugins/web/` | Aurélio Web IDE plugin | TypeScript |
+| `hardware/universal-bridge/` | ESP32/RPi bridge firmware | C, ESP-IDF |

+| `lib/inkstitch/` | Ink/Stitch Inkscape extension submodule | Python |
+| `lib/embroidermodder/` | Embroidermodder 2 submodule | C++, Qt |
+
+## Philosophy
+
+Every submodule added to this repo must be accompanied by a clear statement of **why
+it matters** — what philosophy or grand dream for society made us include it. The
+README.md serves as that statement. When adding new submodules, update README.md with
+the same pattern: one heading, one paragraph of context, one paragraph of why.
+
+## Submodule management
+
+Submodules are pinned to specific commits. To update:
+
+```bash
+# Update all submodules to latest remote
+git submodule update --remote
+
+# Update a specific submodule
+cd lib/pyembroidery && git pull origin main && cd ../..
+git add lib/pyembroidery && git commit -m "chore(submodule): update pyembroidery"
+```
+
+## Vendor registry
+
+`vendor-registry/registry.yaml` is the single source of truth for all known
+embroidery machines. Each entry declares:
+
+- `vendor`: manufacturer name
+- `models`: list of model names/patterns
+- `format`: native stitch format(s)
+- `media`: how designs get into the machine (floppy, card, usb, serial, network)
+- `interface`: electrical interface type (ibmpc, shugart, custom)
+- `jumpers`: Gotek jumper configuration for floppy emulation
+- `hacks`: known community modifications
+- `notes`: quirks, gotchas, references
+
+## MCP server
+
+The MCP server (`mcp/server.py`) exposes embroidery tools to the Aurélio fleet:
+
+- `embroidery_convert` — convert between any supported formats
+- `embroidery_machines` — list known machines from vendor registry
+- `embroidery_preview` — generate stitch preview (PNG/SVG)
+- `embroidery_send` — push design to a connected machine
+- `embroidery_formats` — list supported formats with read/write capabilities
+
+Built on FastMCP. Loads vendor registry at startup. Uses pyembroidery for all
+format operations.
+
+## Build & test
+
+```bash
+# MCP server
+cd mcp
+pip install -r requirements.txt
+python server.py
+
+# Vendor registry validation
+python -c "import yaml; yaml.safe_load(open('vendor-registry/registry.yaml'))"
+```
+
+## Related repos in the fleet
+
+- `replica-omnisciente/` — parent monorepo, contains this repo's context
+- `aurelio-backend-native/` — C23/C++23 backend, may host native digitizing engine

+# Aurélio Embroidery
+
+> *"From artisans to AI. The first art of the Omniscient Replica."*
+
+**Aurélio Embroidery** is the embroidery digitizing, machine control, and universal
+vendor bridge for the Portugal Futurista platform. It plugs into Aurélio Web IDE and
+Aurélio Desktop IDE, giving every artisan the power to draw, digitize, and "print"
+embroidery designs — as easily as 3D printing.
+
+---
+
+## The Grand Dream
+
+My family has a long history of textile creation. I grew up surrounded by fabrics,
+threads, sewing machines, and the slow, beautiful craft of turning raw material into
+adorned cloth. This project is a love letter to that heritage.
+
+The dream is simple: **small embroidery machines that work like a CNC for thread**.
+You draw or create something, press "print," and the machine stitches it out. No
+$2,000 software. No proprietary dongles. No vendor lock-in. Just art → thread → fabric.
+
+But the dream is bigger than convenience. It's about **preserving and teaching the
+old ways** — the *ofícios* — while giving them new life through technology. Imagine
+Guitar Hero, but for learning embroidery. A platform that guides your hands through
+the motions of satin stitch, chain stitch, cross stitch, until muscle memory takes
+over and you're no longer following lights on a screen — you're creating.
+
+This is the start of the **Omniscient Replica**: the first real art, for artists and
+from artisans.
+
+---

+
+---
+
+## Why These Projects Matter
+
+### FlashFloppy — the universal key
+Embroidery machines from the 1990s-2010s read designs from floppy disks. FlashFloppy
+lets you replace that floppy drive with a USB stick. Drop a Gotek ($25) into any
+Tajima, Barudan, Brother, Melco, or Toyota machine, flash this firmware, and you
+have a modern machine that reads designs from USB. **This is the hardware hack that
+unlocks the entire ecosystem.**
+
+### pyembroidery — the universal translator
+Reads 46 embroidery formats, writes 20. Every brand, every variant. This is the
+Rosetta Stone that lets Aurélio speak to any machine ever made. If a format exists,
+pyembroidery can read it, convert it, and write it.
+
+### libembroidery — the embedded engine
+A single C file you drop into any project. 45+ formats, command-line tool (`sew`),
+permissive license. This is what runs on the ESP32 inside the universal bridge.
+
+### Ink/Stitch — the free digitizer
+The ONLY open-source alternative to Wilcom EmbroideryStudio. Full Inkscape
+integration: draw in SVG, export to PES/DST/EXP/JEF/VP3. Satin stitch, fill
+stitch, lettering, auto-column. This is the design tool every artisan deserves.
+
+### Embroidermodder 2 — the free editor
+A Qt-based GUI for viewing, editing, and converting embroidery files. Still in
+alpha, but the vision is complete: a free, cross-platform embroidery editor.
+
+---
+
+## The Universal Bridge
+
+The missing piece — the thing we're building here — is the **Universal Embroidery
+Machine Bridge**: a $15 ESP32-S3 that emulates a floppy drive, serves designs over
+WiFi, and speaks every embroidery format through libembroidery.

+
+## Roadmap
+
+### Phase 1 — Foundation (now)
+- [x] Repository created, vision documented
+- [x] Key submodules added (FlashFloppy, pyembroidery, libembroidery, Ink/Stitch)
+- [ ] Vendor registry populated with all known machines
+- [ ] MCP server skeleton (FastMCP): convert formats, list machines, preview stitches
+
+### Phase 2 — The Bridge
+- [ ] ESP32 universal floppy emulator firmware (based on FlashFloppy logic)
+- [ ] WiFi design upload (drag & drop PES/DST → machine)
+- [ ] Aurélio Desktop IDE plugin: embroidery panel with live preview
+- [ ] Aurélio Web IDE plugin: same, in the browser
+
+### Phase 3 — The Art
+- [ ] Auto-digitizing pipeline (GPU-accelerated: raster/vector → stitches)
+- [ ] 4× 8GB VRAM GPU cluster for batch digitizing
+- [ ] "Guitar Hero for embroidery" — interactive learning mode
+- [ ] Integration with the full Omniscient Replica fleet
+
+### Phase 4 — The Movement
+- [ ] Open hardware reference design published
+- [ ] Community-contributed machine profiles
+- [ ] Teaching curriculum (traditional Portuguese embroidery techniques)
+
+---
+
+## Philosophy
+
+This project exists because **the tools of creation should belong to the creators**.
+
+Wilcom costs $2,000+. Pulse costs $3,000+. The machines are locked to Windows 95
+floppy drives and proprietary dongles. The artisans who keep textile traditions alive
+are locked out by software they can't afford and hardware they can't connect to.
+
+We're breaking that open.
+
+Every line of code in this repo is free. Every machine profile is community-owned.
+Every design you make is yours. The GPUs in our lab (4× 8GB when the fleet is back
+online) will accelerate the hard parts — auto-digitizing, stitch simulation, preview
+rendering — so your laptop doesn't have to.
+
+This is Portugal Futurista's contribution to the world's textile heritage:
+**the tools, the knowledge, and the bridge between tradition and tomorrow.**

+vendors:
+  - vendor: Tajima
+    models:
+      - "TME*"   # TME series (multi-head electronic)
+      - "TMB*"   # TMB series (bridge type)
+      - "TMEX*"  # TMEX series
+      - "TF*"    # TF series
+    formats: [dst, dsb, dsz, tbf]
+    media: floppy
+    floppy:
+      interface: ibmpc
+      density: hd    # 1.44MB
+      sectors: 18
+      tracks: 80
+    jumpers: [JC, S1]
+    connectivity:
+      - gotek_flashfloppy   # Drop-in Gotek + FlashFloppy (JC+S1)
+      - tajima_dgml_network # Official Tajima LAN adapter (expensive)
+    notes: |
+      The industry standard. DST is the universal format — every machine reads it.
+      Most Tajima machines use IBM PC floppy interface. Some older models (pre-1995)
+      use Shugart (jumper S0 only). DST has no color information — color sequence
+      must be managed separately.
+
+  - vendor: Barudan
+    models:
+      - "BE*"   # BE series
+      - "BEX*"  # BEX series
+      - "BES*"  # BES series
+    formats: [dst, dsb, u01, fdr, fmc, dat]
+    media: floppy
+    floppy:

+      density: hd
+    jumpers: [JC, S1]
+    connectivity:
+      - gotek_flashfloppy
+      - barudan_ethernet
+    notes: |
+      Barudan machines are workhorses. Same interface as Tajima for floppy.
+      The U01 format is Barudan-specific. FDR/FMC are older Barudan formats.
+
+  - vendor: Brother
+    models:
+      - "PR*"     # PR series (professional)
+      - "PE*"     # PE series (home/consumer)
+      - "NV*"     # Innov-is series
+      - "LB*"     # Labelle / limited edition
+      - "BES*"    # BES series
+      - "HE*"     # HE series
+    formats: [pes, pec, phb, phc]
+    media: [floppy, card, usb]

+      - flashair_wifi_sd       # WiFi SD in card slot
+      - usb_direct             # USB port on newer models (PR1050X+)
+    notes: |
+      PES is the most common consumer embroidery format. Brother machines from the
+      2000s used proprietary memory cards; later models added USB. The Brother
+      card writer is a commercial product but expensive. FlashAir WiFi SD in a
+      card adapter is the popular hack.
+
+  - vendor: Melco
+    models:
+      - "EMT*"   # EMT series
+      - "EP*"    # EP series
+      - "Amaya*"
+      - "Bravo*"
+    formats: [exp, cnd, ofm]
+    media: [floppy, serial, network]
+    floppy:

+      density: hd
+    jumpers: [JC, S1]
+    connectivity:
+      - gotek_flashfloppy
+      - melco_actifeed       # Melco network adapter
+      - melco_usb_interface
+    notes: |
+      Melco created the first embroidery sample head (1980). EXP is Melco's
+      format. The Amaya/Bravo lines have networking built-in but older EMT/EP
+      machines are floppy-only or RS-232 serial.
+
+  - vendor: Janome
+    models:
+      - "MC*"    # Memory Craft series
+      - "MB*"    # MB series
+    formats: [jef, jef+, sew]
+    media: [floppy, compactflash, usb]
+    floppy:

+      density: hd
+    jumpers: [JC, S1]
+    connectivity:
+      - gotek_flashfloppy
+      - cf_to_sd_adapter     # CompactFlash → SD adapter
+      - janome_usb_cable     # Janome USB cable (commercial)
+      - clothset             # Janome Clothset USB
+    notes: |
+      JEF is Janome's format. Machines from the MC series used floppy, then CF.
+      CF-to-SD adapters work for newer machines. Older MC models require the
+      proprietary USB cable.

+    notes: |
+      HUS/SHV/VIP/VP3 are all Viking/Pfaff formats. VP3 is the most modern.
+      Viking machines use a proprietary USB stick (not a standard USB port).
+
+  - vendor: Pfaff
+    models:
+      - "Creative*"
+      - "Performance*"
+    formats: [vp3, pcs, ksm, max]

+      - gotek_flashfloppy
+      - pfaff_usb_stick
+    notes: |
+      Pfaff and Viking share formats (both owned by SVP Worldwide). VP3 is the
+      modern format. PCS is the older card format.
+
+  - vendor: Bernina
+    models:
+      - "Artista*"
+      - "880*"
+      - "790*"
+      - "770*"
+      - "570*"
+    formats: [art, exp]
+    media: [usb_stick, card]
+    connectivity:
+      - bernina_usb_stick    # Bernina-branded USB stick
+      - flashair_wifi_sd     # WiFi SD in card slot
+    notes: |
+      ART is Bernina's proprietary format — it's encrypted/DRM'd. Third-party
+      software can write ART but Bernina machines may reject files not signed
+      by Bernina software. The USB stick must be Bernina-branded (or hacked).
+      EXP (Melco) is also supported on some models.
+
+  - vendor: Toyota
+    models:
+      - "ES*"    # ES series

+# ─── Gotek / FlashFloppy Reference ──────────────────────────────────────
+#
+# Universal floppy emulator configuration:
+#
+#   Standard IBM PC (95% of embroidery machines):
+#     Jumpers: JC + S1
+#     FF.CFG:  interface = ibmpc
+#     Image:   FAT32 USB, 1.44MB IMG files
+#
+#   Shugart (older machines, pre-1995):
+#     Jumpers: S0 only
+#     FF.CFG:  interface = shugart
+#     Image:   FAT32 USB, 720KB or 1.44MB IMG files
+#
+#   Other interface modes available in FlashFloppy:
+#     ibmpc-hdout, akai-s950, amiga, jc, shugart, ibmpc, pc98, ensoniq
+#
+# USB stick preparation:
+#   1. Format USB stick as FAT32
+#   2. Copy blank IMG files (created with dd or HxCFloppyEmulator)
+#   3. Rename to DSKA0000.IMG, DSKA0001.IMG, etc.
+#   4. On the machine, format each "disk" before use
+#   5. Use pyembroidery or Embird to write designs to the IMG files on PC
+#
+# FlashAir WiFi SD hack:
+#   1. Get Toshiba FlashAir W-04 (or ezShare WiFi SD)
+#   2. Configure as AP or station mode
+#   3. Map the SD card as a network drive on PC
+#   4. Insert into machine's SD/PCMCIA card slot via adapter
+#   5. Designs dropped into the network folder appear on the machine
+#
+# ESP32 Universal Bridge (TO BE BUILT):
+#   - ESP32-S3 bitbangs floppy signals on GPIO
+#   - SD card slot for local storage
+#   - WiFi for network design upload
+#   - pyembroidery running on-device for format conversion
+#   - Web interface at http://embroidery.local
