Define a minimal named Resource envelope with exact URI identity, opaque type tags, strict uniqueness and shape validation, and no runtime lifecycle semantics. agent-session-id: dev3.dotfiles-cos-misc-st2-resource-design agent-tool: Codex agent-tool-version: 0.145.0 agent-model: gpt-5.6-sol agent-runtime-profile: /home/schickling/.local/state/agent-session-recovery/2026-07-29-pty-st2-cutover/runtime-profile/profile-without-null-opencode.json agent-skills-manifest: /nix/store/kx5j47nghj1yps2v693ryb6wnf1c2xhb-agent-skills-corpus/share/agent-skills/manifest.json tooling-profile: dotfiles@16a22c6
Validate exact RFC 3986 syntax without normalization, keep public serde on the same strict schema, and expose declared descriptors through the stable agents JSON roster. agent-session-id: dev3.dotfiles-cos-misc-st2-resource-design agent-tool: Codex agent-tool-version: 0.145.0 agent-model: gpt-5.6-sol agent-runtime-profile: /home/schickling/.local/state/agent-session-recovery/2026-07-29-pty-st2-cutover/runtime-profile/profile-without-null-opencode.json agent-skills-manifest: /nix/store/kx5j47nghj1yps2v693ryb6wnf1c2xhb-agent-skills-corpus/share/agent-skills/manifest.json tooling-profile: dotfiles@16a22c6

Why
Agent declarations need a portable way to name the external resources an agent depends on without copying payloads or making st2 own downstream schemas, access, readiness, or lifecycle policy.
What
Add a direct named Resource envelope to Agent Spec:
The public
agent-specmodel preserves bindings in deterministic name order across KDL, TOML, and JSON. Names are unique,_tagstays opaque to st2, anduriis validated as RFC 3986 absolute syntax while its exact bytes remain unnormalized. Public serde uses the same strict invariants and rejects unknown policy fields.st2 agents --json [--enrich]exposes each declaration's orderedresourcesdescriptors for language-neutral inspection, including unknown downstream tags.VRS requirements R20-R21 define the portable envelope and its observable, nondisruptive runtime boundary; the implementation spec traces directly to them.
Rationale
The envelope intentionally contains only the agent-local semantic name, concrete type discriminator, and URI identity. Unsupported policy properties fail closed so callers cannot mistake ignored fields for enforcement. Resource bindings are excluded from task launch targets; a resource-only edit adopts a healthy live task without replacement or relaunch.
This does not project folder-eval resources or define resolution, readiness, access, lifecycle, or mutation semantics.
