# PHOSPHOR — Spacetime, EAI, MCCP

PHOSPHOR offers three independent local packages under Apache-2.0. Canonical website: https://emlphosphor.com/. Preview source repository: https://github.com/EveMissLab/PHOSPHOR.

## Start here
- https://emlphosphor.com/spacetime/ — install the software-spacetime reference runtime and control a native logical-time demo
- https://emlphosphor.com/ai/manifest.json — versions, packages, downloads, reading order, and rights
- https://emlphosphor.com/ai/corpus/current.md — current capabilities and boundaries
- https://emlphosphor.com/ai/corpus/spacetime.md — authority, temporal control, benchmarks, and gates
- https://emlphosphor.com/mccp/ — local Python tracing and graph inspection
- https://emlphosphor.com/#playground — the EAI browser playground

## Runnable source
- /download/phosphor-preview-source.zip — all three independently installable packages; read README.md first
- /download/phosphor-spacetime-v0.1.0a9-source.zip — Spacetime M0–M10 plus Preview delivery fixes and temporal-demo
- /download/phosphor-eai-v0.8.0-beta-source.zip — EAI VM/WASM, CTS, stream, spreadsheet, UI, and site
- /download/phosphor-mccp-v0.0.1-source.zip — Python collector, graph, lenses, API, and UI
- /download/manifest.json — exact archive SHA-256 and sizes

Spacetime: Python >= 3.12; install from its folder with `python -m pip install -e ".[dev]"`; run `pss temporal-demo --rate 2.5 --quanta 20`, `pss matrix C_EVENT_SPARSE`, and `pss gate --git-commit UNKNOWN`. These commands need no API key. Logical rate is native to the synthetic runtime. CPU throttling on Windows/Linux does not rewrite an arbitrary program's logical clock. Most bundled benchmarks are synthetic; AI performance superiority remains unproven.

EAI 0.8.0-beta: Node >= 22; `npm ci`, `npm run typecheck`, `npm run verify:wasm`, and `npm run phosphor -- run --program fibonacci --max 40`. The UI has eleven tabs and uses the same engine. The historical v0.5 spec describes the base semantics; later WASM, spreadsheet, and retrofit additions are in the release and retrofit documents.

MCCP 0.0.1: local Python tracing and graph views work without a model key. Optional AI explanations require ANTHROPIC_API_KEY and send selected trace evidence to the configured model. The optional raw-timeline viewer uses external Perfetto. Keep trace output local.

## Execution boundaries
Three independent engines and event protocols. The website hosts static documents, downloads, and the browser EAI playground. HTTP/MCP control endpoints are declared, not hosted. Observation and capability do not grant authority. Unsupported or ambiguous mutations fail closed.
