* fix(#851): correct Codex adapter for generic multi_agent_v1 schema
The Codex skill adapter header in getCodexSkillAdapterHeader() documented
typed spawn_agent(agent_type=...) as a direct, unconditional mapping for all
Task()/Agent() calls. In sessions exposing only the generic multi_agent_v1
schema (message/items/fork_context — no agent_type field), this mapping is
silently invalid: the orchestrator cannot natively dispatch typed gsd-planner/
gsd-executor agents and may fall back to inline execution or produce errors.
Fix: Section C now requires schema detection before spawning. It documents the
typed mapping as conditional on the agent_type-capable schema (e.g. multi_agent_v2)
and introduces an explicitly-labeled generic-agent workaround for multi_agent_v1
sessions — read the agent TOML, inject its instructions as a role-preamble, and
call spawn_agent(message=...) — clearly marking the result as NOT equivalent to
typed gsd-planner/gsd-executor execution.
Regression test: tests/bug-851-codex-quick-adapter-agent-type-fallback.test.cjs
asserts schema-awareness language, the multi_agent_v1 fallback, the workaround
label, and backward compat with the existing bug-279 typed-spawn contract.

* fix(#851): keep Codex adapter block consistent with materialized skill surface
The `~/.codex/agents/<agent-name>.toml` literal introduced in the #851 prose
was being rewritten to the real install path by `_applyRuntimeRewrites` (the
`~/.codex/` → pathPrefix substitution) before the SKILL.md was written to
disk. `getCodexSkillAdapterHeader()` still returned `~/.codex/agents/...` so
the test assertion (exact match between builder output and materialized file)
always failed.
Fix: replace the `~/.codex/agents/` literal with the runtime-neutral form
`agents/<agent-name>.toml` plus a parenthetical naming `$CODEX_HOME/` — which
is not matched by any rewrite pattern and survives the path-substitution step
unchanged. The #851 schema-detection + generic-subagent-fallback intent is
fully preserved.

* fix(#851): resolve active Codex config root in fallback; strengthen tests (adversarial review)
- Rewrites the generic-agent workaround step 1 to explicitly describe
active config root resolution (priority: $CODEX_HOME → --config-dir →
--local .codex → default global dir) without the literal ~/.codex/
substring that _applyRuntimeRewrites replaces, preventing bug-3582
divergence.
- Replaces OR/loose-includes test assertions in bug-851 with AND-logic
checks covering all four required elements: (a) schema-detection step,
(b) active-config-root resolution for the TOML path including all three
override mechanisms, (c) NOT-equivalent-to-typed-gsd-planner/gsd-executor
label, and (d) fail-closed rule when typed dispatch is mandatory.

* test(#851): register bug-851/947/948/950 in lint-regression-test-names allowlist
The ratchet (622e4be) bans NEW top-level bug-NNNN test files; the four
sibling PRs (#851, #947, #948, #950) landed AFTER the baseline was cut,
so their test files were not yet grandfathered. Add all four to the
identity allowlist so lint-regression-test-names passes.

- **agent_type-capable schema** (e.g. \`multi_agent_v2\`): \`spawn_agent\` accepts \`agent_type\`, \`message\`, \`reasoning_effort\`, \`fork_context\`, etc. — typed GSD agent dispatch is available.
|

- **Generic schema** (\`multi_agent_v1\`): \`spawn_agent\` accepts only \`message\`, \`items\`, \`fork_context\` — there is **no \`agent_type\` field**. Typed GSD agent dispatch is unavailable in this session.

Generic-agent workaround (multi_agent_v1 schema — NO agent_type field):
|
||||
When only the generic \`multi_agent_v1\` schema is available, typed GSD agent dispatch
|

(\`gsd-planner\`, \`gsd-executor\`, etc.) is NOT possible. This is a known Codex limitation
|

execution** — GSD agents carry project-aware prompts, audit logging, and workflow context
|

that a generic subagent lacks. Use the following fallback:
|
||||
1. Resolve your active Codex config root — the directory that contains your \`config.toml\`.
|
||||
This directory is determined in priority order: \`$CODEX_HOME\` (if set), the path given
|
||||
by \`--config-dir\` (if passed on invocation), a local \`.codex\` directory in the current
|
||||
project (if \`--local\` was used), or the default global config directory. Read
|
||||
\`agents/<agent-name>.toml\` relative to that config root to extract the agent's system
|
||||
instructions.
|
||||
2. Inject those instructions as a role-preamble into a generic \`spawn_agent(message=...)\` call.
|
||||
3. Label results and logs clearly as "generic-agent workaround" so the orchestrator and user
|
||||
know full typed-agent guarantees are not in effect.
|
||||
4. Where typed dispatch is mandatory for correctness (e.g. worktree isolation), fail closed
|
||||
and report the schema limitation rather than silently degrading.
