64 — Forgeyard Remote Development Environments, Cloud Workspaces, Codespaces-Style Sessions & Developer Workspace Orchestration System Architecture

Document type: Core Remote Development Environment, Cloud Workspace, Developer Session, Prebuild, Workspace Persistence, IDE/Terminal Access & Developer Environment Orchestration System Architecture
Project: Forgeyard CI/CD
Subsystem: ephemeral remote developer workspaces, local/remote parity, workspace templates, exact source/toolchain/environment identity, prebuilds, persistent developer volumes, workspace suspension/resume, secure terminal/IDE access, port forwarding, private network access, developer secrets, per-workspace credentials, environment drift, cost/TTL governance, workspace snapshots, recovery, and promotion boundaries between development and CI/CD
Architecture style: Reproducible developer environments, explicit workspace identity, disposable compute with bounded persistent state, zero-trust access, exact source snapshots, prebuild acceleration, dev/CI parity, no hidden release authority, and no undeclared dependency on mutable workstation state
Status: Target production architecture extending the Forgeyard series beyond the original 01–26 plan
Relationship to prior work: Builds on Developer Experience/Local Dev, Runner/Agent, Sandbox/Executor, Toolchains, Test Environments, Infrastructure-as-Code, Network Connectivity, Secrets/Trust, Runner Image Factory, Configuration, Multi-Tenancy/Quotas, Cost/FinOps, Identity/Authz, Audit, Observability, and Data Lifecycle. This subsystem gives Forgeyard a first-class remote development workspace model without compromising CI determinism or supply-chain trust.

1. Purpose

Developers increasingly work in environments that are not their physical laptops:

remote Linux workspaces
cloud VMs
ephemeral containers
browser IDEs
SSH/terminal sessions
remote Dioxus/desktop IDE clients
GPU development workspaces
device-development hosts
on-prem development nodes
air-gapped engineering environments

A remote workspace can improve:

onboarding
toolchain consistency
performance
large monorepo access
private-resource access
GPU availability
cross-platform development
reproducibility

But unmanaged remote environments also create risks:

persistent snowflake machines
developer secrets in disks
shared SSH keys
stale source trees
untracked package installation
hidden build dependencies
long-lived production credentials
unbounded compute cost
workspace data leakage

The central rule is:

A developer workspace is a user-facing mutable working environment, but its reproducible base, source identity, toolchains, permissions, network reachability, and persistent state must be explicit.

A second rule is:

Remote workspace success never substitutes for CI validation. A developer can experiment freely inside a workspace, but release/build authority remains with normal Forgeyard pipelines and evidence.

A third rule is:

Persistent developer convenience state must be separated from authoritative build inputs. Personal caches, editor state, and writable home directories are never silently incorporated into derivation identity.

3. Goals

The subsystem MUST:

define workspace identity;
define workspace template identity;
define developer environment identity;
support local and remote workspace parity;
support cloud and on-prem providers;
support ephemeral workspaces;
support persistent developer volumes;
support exact toolchain setup;
support source checkout/snapshot identity;
support prebuilds;
support suspension/resume;
support workspace recreation;
support secure IDE access;
support terminal access;
support port forwarding;
support private network resources;
support scoped developer secrets;
support short-lived credentials;
support per-user authorization;
support quotas and TTL;

release systems
IDE products
desktop OS management
VDI products
endpoint management

It orchestrates developer workspaces around Forgeyard’s reproducible environment model.

6. DeveloperWorkspaceId

#![allow(unused)]
fn main() {
pub struct DeveloperWorkspaceId(Ulid);
}

Represents one live or historical developer workspace instance.

7. WorkspaceTemplateId

#![allow(unused)]
fn main() {
pub struct WorkspaceTemplateId(Digest);
}

Immutable normalized definition of the desired developer environment.

8. WorkspaceTemplate

#![allow(unused)]
fn main() {
pub struct WorkspaceTemplate {
    pub id: WorkspaceTemplateId,
    pub project: ProjectId,
    pub platform: WorkspacePlatform,
    pub toolchains: Vec<ToolchainDescriptorId>,
    pub services: Vec<WorkspaceServiceRef>,
    pub network: WorkspaceNetworkPolicyId,
    pub resources: WorkspaceResourceSpec,
}
}

9. Workspace Platform

#![allow(unused)]
fn main() {
pub enum WorkspacePlatform {
    Linux,
    Windows,
    MacOS,
    Custom(PlatformId),
}
}

Remote Linux is expected to be the baseline.

Windows/macOS use real platform hosts where required.

10. Source Identity

Workspace attaches to:

RepositoryId
RevisionId
SourceSnapshotId

Branch name is navigation metadata, not canonical source identity.

11. Dirty Working Tree

Allowed.

12. DirtyWorkspaceSnapshotId

#![allow(unused)]
fn main() {
pub struct DirtyWorkspaceSnapshotId(Digest);
}

When needed, Forgeyard can snapshot the working tree explicitly.

13. CI From Workspace

If developer runs CI from dirty workspace:

capture explicit dirty SourceSnapshotId
  ↓
CI runs against immutable snapshot

No CI runner reads developer filesystem live.

14. Critical Boundary

workspace mutable filesystem
    !=
CI source input

CI consumes explicit immutable snapshot.

15. Workspace State

#![allow(unused)]
fn main() {
pub enum DeveloperWorkspaceState {
    Requested,
    Provisioning,
    Starting,
    Ready,
    Active,
    Suspended,
    Resuming,
    Stopping,
    Stopped,
    Failed,
    Unknown,
}
}

16. Unknown

Provider outcome uncertain.

Inspect before duplicate provision/start/stop.

17. Workspace Ownership

#![allow(unused)]
fn main() {
pub struct WorkspaceOwner {
    pub principal: PrincipalId,
    pub tenant: TenantId,
    pub project: ProjectId,
}
}

295. Core Tests

Identity

template identity deterministic;
mutable base alias resolves exact image.

Source

dirty workspace run captures immutable SourceSnapshotId;
runner never reads live workspace filesystem.

Prebuild

prebuild cache miss still works;
secret-bearing prebuild is not globally reusable.

Sessions

expired session denied;
static shared SSH key absent;
public port requires explicit permission.

Secrets

production secret unavailable in standard dev workspace;
no secret baked into image/snapshot.

Volumes

cross-user mount denied;
delete warns on dirty/unpushed work.

Drift

base/security drift triggers recreate requirement;
user shell customization does not corrupt template identity.

Cost/TTL

idle suspend preserves data;
budget pressure never silently deletes active dirty work.

Federation

residency blocks disallowed region;
air-gap blocks public egress.

Security

workspace cannot act as release/signing runner.

296. Chaos Tests

Inject:

cloud VM provision timeout
volume attach failure
workspace-agent crash
region outage
session gateway outage
prebuild service outage

Expected:

workspace state remains explicit
no duplicate instance creation
persistent data durability follows declared policy
sessions recover or fail cleanly

297. Scale Tests

Test:

thousands of active workspaces
large prebuild fanout
large monorepo checkout/index
high concurrent session count
large persistent volume fleet

Every workspace has immutable WorkspaceTemplateId.
Workspace source revision resolves to exact SourceSnapshotId.
Dirty workspace CI captures explicit immutable snapshot.
CI never builds directly from live mutable workspace filesystem.
Workspace base image is exact/digest-bound.
User customization is separate from reproducible base identity.
Prebuilds are optional acceleration only.
Prebuild failure does not make workspace fundamentally unusable.
Secret-bearing prebuilds are not shared broadly.
Developer persistent volumes are tenant/user/project scoped.
Cross-user/cross-tenant mounts are denied by default.
Production data is not present by default.
Production secrets are denied in standard workspace profile.
Credentials are late-bound and short-lived.
No static shared SSH key is required.
Port forwards are explicit and expiring.
Public port exposure requires separate permission.
Workspace network reachability does not imply service authorization.
Workspace compute can suspend independently from persistent state.
Security/base drift can require workspace recreation.
Remote workspace is never automatically trusted as release/signing runner.
Long-running reproducible work can be promoted into a normal JobSpec.
Budget/TTL policy cannot silently delete active dirty work.
Workspace deletion warns/protects unpushed work according policy.
Workspace snapshots exclude secrets by design.
DR behavior reflects actual persistent-volume durability/RPO.
Federation placement obeys residency.
Air-gapped workspaces run without public egress.
Admin/support access is explicit and audited.
Forgeyard dogfoods remote workspaces for its own development.

300. Production Readiness Gates

Do not call remote workspaces production-ready until:

workspace/source identity is stable
dirty-source snapshotting works
session credentials are short-lived
persistent volume isolation is proven
production-secret denial is enforced
public port controls are machine-enforced
prebuild isolation/cache rules pass
suspend/resume and provider Unknown reconciliation work
DR/RPO behavior is documented and tested
security/chaos/scale tests pass

301. Architectural Invariants

workspace base is reproducible;
user mutable layer is separate;
branch name is not source truth;
dirty CI uses explicit snapshot;
CI never consumes live workspace filesystem;
prebuild is acceleration only;
persistent state is explicit;
caches are disposable;
secrets are not baked into workspace image/snapshot;
standard workspace lacks production secrets;
session credentials are short-lived;
no static shared SSH key baseline;
port forwards are scoped/expiring;
network reachability is not authorization;
workspace can suspend independently from persistent state;
base/security drift affects freshness;
developer workspace is not trusted release runner;
workspace process state is never “promoted” into CI;
reproducible long work becomes a normal JobSpec;
user/admin access boundaries are explicit;
no silent session/keystroke recording baseline;
public exposure requires explicit permission;
tenant/user volume isolation is enforced;
quota/cost policies preserve dirty work safely;
data lifecycle governs snapshots/volumes;
DR promises match actual persistence durability;
federation obeys residency;
air-gap blocks public egress;
provider effects are reconciled after ambiguity;
Forgeyard dogfoods its own remote workspace system.

                     Normal CI

State separation:

Immutable base
    +
Project/template layer
    +
Persistent developer volume
    +
Disposable cache
    +
Ephemeral credentials

CI boundary:

developer workspace
      ↓
capture exact source snapshot
      ↓
normal Forgeyard pipeline
      ↓
trusted runners/evidence
      ↓
release

The key guarantee is:

Forgeyard can offer fast, persistent, cloud-hosted development environments without weakening its local-first and reproducible CI architecture. Developers keep mutable, personalized workspaces for productivity, while every transition into CI/release crosses an explicit immutable snapshot boundary and re-enters the normal governed Forgeyard pipeline.
