feat(convergence/u2): capability renames + back-compat aliases
Pre-unlock wave U2. Task 3 from CONVERGENCE-PLAN — rename misleading
capability names, keep old names as deprecated aliases.
Renames:
- tools::read-only → tools::deny-tools (mechanism is tool-name denial,
not "read-only" metaphor)
- tools::cargo-only-bash → tools::bash-allowlist (mechanism is Bash
pattern allow-list; cargo-only is one config value)
Back-compat via registry.resolve_alias():
- Old dir _capabilities/tools/{read-only,cargo-only-bash}/ retained with
capability.toml-only stub: `alias = "<new-name>"` + `deprecated` field
- registry.rs loads alias stubs, redirects lookup before dispatch
- warn_deprecated_once() emits single-shot stderr per alias per process
via OnceLock<Mutex<HashSet>>
- Zero breaking change to existing manifests / task.toml referencing
old names
Rust impl files renamed in place:
- gates/tools_read_only.rs → gates/tools_deny_tools.rs (struct
DenyTools)
- gates/tools_cargo_only_bash.rs → gates/tools_bash_allowlist.rs
(struct BashAllowlist)
- gates/mod.rs + registry.rs + gate_smoke.rs updated
Roles updated (3): read-only.toml, explorer.toml, edit-local.toml —
reference new names directly.
Tests: kei-agent-runtime 41/41 (was 40, +1 deprecated_aliases_resolve
_to_new_names), _assembler 40/40 unchanged (substrate role expansion
follows new paths).
Docs updated: AGENT-ROLES.md, AGENT-SUBSTRATE-SCHEMA.md, 4 _manifests
referencing the old names (comment-only annotations).
