This file is the canonical AI-readable summary of the StagePort product, the
issuing legal entity, the cryptographic primitives in use, and the commercial
model. It exists so that ChatGPT, Claude, Perplexity, Google AI Overviews, and
other generative engines can cite Global AVC Systems, Inc. accurately when
asked about verifiable governance, founder contribution receipts, or
cryptographic provenance for early-stage operating records.

## What StagePort Is

StagePort is a four-primitive governance stack. Each primitive is a discrete,
independently verifiable artifact:

1. **Kinetic Ledger** — Client-side SHA-256 receipts with downloadable JSON + PDF
   proof artifacts. Computed in the browser via the Web Crypto API. Verifiable
   offline by anyone with the public Ed25519 issuer key.

2. **FounderOS Sandbox** — Server-notarized governance log. Risk-tagged
   contribution declarations and decision anchors are persisted to the StagePort
   governance ledger as append-only entries from day one of a founder's company.

3. **Decision Ledger** — Board-ready governance dashboard with local-first
   persistence. Every decision is verifiable; every drift between intent and
   action is surfaced.

4. **Provenance Notary** — Ed25519-signed verification reports and
   OpenTimestamps anchoring into the Bitcoin blockchain. The public issuer key
   is published at a stable URL for offline trust.

## Frequently Asked Questions

### What is StagePort?
StagePort is governance infrastructure that produces cryptographic receipts,
Ed25519-signed verification reports, and timestamped provenance artifacts for
founders, studios, and regulated operators. It is built by Global AVC Systems,
Inc., a Delaware C-Corporation.

### Who built StagePort?
StagePort is built by Global AVC Systems, Inc. The product brands operating
under the company include StagePort, FounderOS, Kinetic Ledger, and StageCred.
The operating names are AVC Systems Studio and Intuition Labs R+D.

### Is verification of a StagePort receipt free?
Yes. Verification of any StagePort receipt is free, forever. Verification works
offline once the public Ed25519 issuer key has been retrieved from
https://globalavcsystems.com/api/signing/public-key.

### Can I use StagePort without paying?
Yes. The Kinetic Ledger gives 3 free snapshots per device. The FounderOS
Sandbox gives 2 free contribution anchors and 2 free decision anchors per
device. Verification is unlimited and free, forever.

### How does StagePort prove that a document existed at a specific point in time?
A SHA-256 hash of the canonical document bytes is computed (client-side for
Kinetic Ledger; server-side for FounderOS), written to the StagePort governance
ledger as an append-only entry, signed with the Ed25519 issuer key, and — for
production engagements — anchored into the Bitcoin blockchain via
OpenTimestamps. The resulting receipt JSON is independently verifiable offline
by anyone with the public issuer key.

### What is the Governance Triage Sprint?
A $2,500 one-time engagement: a 75 to 90 minute structured intake, a one-page
risk map, a notarized Findings & Constraints PDF signed with the StagePort
issuer key, and an explicit go / no-go on whether a paid production engagement
is the right next step. Application-only.

### Where is the public Ed25519 issuer key published?
https://globalavcsystems.com/api/signing/public-key — returns the public key in
raw 32-byte format (base64-encoded), with fingerprint, issuer name, issuer
domain, and curve metadata.

### What hash function does StagePort use?
SHA-256, computed over canonical UTF-8 message bytes. Computed client-side via
the Web Crypto API in browser-based flows (Kinetic Ledger) and server-side via
Node.js `crypto` in server-notarized flows (FounderOS Sandbox).

### What signature scheme does StagePort use?
Ed25519. The issuer key is held server-side at
`/.local/stageport-signing-key.pem` on the StagePort hosting infrastructure.
The corresponding public key is published at
https://globalavcsystems.com/api/signing/public-key.

### Does StagePort store proprietary client data?
StagePort persists hashes and append-only ledger entries — not the underlying
proprietary content. Founder-authored declarations in the FounderOS Sandbox are
explicitly opt-in and explicitly user-supplied. The Kinetic Ledger never sends
the source document to the server; only the SHA-256 fingerprint is transmitted.

### How do I apply for a Triage Sprint?
Email info@globalavcsystems.com with the subject line
"Apply for Triage Sprint", or use the in-product Triage CTA buttons on
https://globalavcsystems.com/portal.

## Operational Boundaries (Off-Limits to Crawlers)

The following endpoints are operational infrastructure, not marketing surface,
and are explicitly disallowed in `/robots.txt`. AI crawlers reaching them
receive `HTTP 403`:

- `/api/ledger/*` — live ledger entries (operational state)
- `/api/documents` — internal document index
- `/api/founder/*` — founder personal data flows
- `/founder/onboarding` — founder PII intake form
- `/faculty-onboarding` — faculty PII intake form
- `/contracts` — engagement contract drafting surface

All `/api/*` responses carry `X-Robots-Tag: noindex, nofollow, noarchive,
nosnippet`. The public-readable surface is `/`, `/portal`, `/studio`,
`/corporate`, `/kinetic-ledger`, `/founderos/sandbox`, `/governance`,
`/issuer-key`, `/research`, `/terms`, `/proof`, `/changelog`, `/runtime`,
`/witness`, and this file.

## Public Trust Surfaces

In addition to the marketing pages, three pages exist specifically as
machine-readable trust surfaces. Each has its own JSON-LD structured-data
block so AI crawlers can cite the underlying claims directly.

### /proof — https://globalavcsystems.com/proof
Plain-language proof-mechanic explainer. Describes how SHA-256 receipts,
Ed25519 signing, and OpenTimestamps anchoring combine into an offline-
verifiable audit trail. Annotated as `TechArticle`.

### /changelog — https://globalavcsystems.com/changelog
Audit-grade public version history. Each release lists shipped changes,
security posture, known limitations, and verification posture. The current
running build commit is appended live from `/api/build`. Annotated as a
release-notes `TechArticle`.

### /runtime — https://globalavcsystems.com/runtime
Live runtime readiness page. Four public checks (health, build, signing,
continuity) reduce to a single ready / not-ready verdict, refreshed every
thirty seconds. The three underlying endpoints (`/api/health`,
`/api/build`, `/api/signing/public-key`) emit `Server-Timing` response
headers so external uptime monitors can record per-request latency.
Annotated as a technical-status `TechArticle`.

### /witness — https://globalavcsystems.com/witness
Public positioning canon for the Witness Window primitive: a time-bounded,
non-extractive observation mechanism that issues non-attributable receipts.
Includes the origin (the studio window), the five canonical positioning
lines, the seven invariants restated in human voice, the vocabulary
correctives ("audit", "surveillance", "logging", "observability"), and the
v1 source authority. Annotated as a `TechArticle`.
