Fabro's policy layer restated the lithos built-ins under `metadata.fabro`:
enabled flags, credentials, display facts, probe and small-default roles,
and agent profiles. lithos-llm now carries every one of those as a core
field or under the shared `metadata.agent` namespace, so the layer and its
typed view go:
- Delete `fabro-policy.toml` and `FABRO_POLICY_TOML`. The catalog is the
lithos built-ins plus the operator's `[llm]` overlay, nothing between.
- Delete `fabro_types::catalog_policy`. `enabled`, `stands_in_for`,
`api_key_url`, `family`, the cutoffs, `estimated_output_tps`,
`small_default`, and `probe` are read from lithos accessors; the agent
profile and `reasoning_by_default` come from `metadata.agent`, which
Pebble reads too.
- `catalog::provider`, `enabled_providers`, and `listed_providers` return
the lithos `CatalogProvider` directly; `ModelEntry` loses its policy
field and gains `agent_profile()`.
- Test fixtures move `[providers.x.metadata.fabro] enabled = true` onto
the provider table, drop `credentials` lists in favor of the secret name
lithos derives from the provider id, and spell `agent_profile` as
`metadata.agent.profile`.

lithos-llm now owns which named secrets each provider reads and how they
shape into its auth scheme, including a derived `<PROVIDER>_API_KEY` for
operator-defined providers. Fabro's job shrinks to supplying the store:
`VaultCredentialSource` hands lithos a lookup that reads the process
environment, then the vault, under the same conventional names.
What Fabro still adds on top: the Codex OAuth credential in the vault,
refreshed and persisted when it expires; `{{ secrets.NAME }}` tokens in a
provider's `default_headers`, resolved against the vault and re-sent as
credential headers; and OpenAI organization and project headers from the
environment.
Deleted with the `metadata.fabro.credentials` list: `CredentialRef`,
`CredentialResolver`, `EnvCredentialSource` (now
`VaultCredentialSource::environment_only`), and the `env_var_names` /
`expected_vault_secret_name` helpers, replaced by `secret_names` and
`expected_secret_name` over the lithos table. `openai-codex` joins the
first-party provider id constants.

fabro-llm is now a thin integration crate: catalog construction from the
lithos built-ins, the Fabro policy layer, and operator overlays; client
construction from catalog plus credentials; a Fabro `ModelResolver` that
enforces `metadata.fabro` policy; model selection; a server gateway
adapter; attachment inlining middleware; reasoning normalization;
one-shot structured output; probe wiring; and catalog API views. The
in-house codecs, transports, providers, tool loop, retry, cost, and
token-count code are deleted along with the wire snapshots that covered
them.
fabro-agent consumes lithos `StreamEvent`s and `Response`s directly.
Retry is split: lithos's retry middleware handles failures before any
visible output, and the agent replays the turn after.

Brave stays the default. Shops that already vault VENICE_API_KEY
can drop BRAVE_SEARCH_API_KEY by setting
[server.integrations.search] provider = "venice".

The shell executor rendered every returned ExecResult and returned
Ok(output), so nonzero exits, timeouts, and cancellations reached
execute_one_tool() as successes. That false ToolResult propagated
consistently: agent.tool.completed recorded is_error: false, the success
post-tool hook ran, Anthropic saw is_error: false, OpenAI Responses saw a
completed function-call output, and CLI/web rendered a successful tool
call.
ExecResult::is_success() is now the authoritative predicate. The executor
runs through exec_command_streaming() with a sink callback, so it keeps
the production providers' stream provenance and partial-output capture,
and drops the exec 2>&1 prefix that merged stderr into stdout before
Fabro could report it. Model-facing text labels termination, exit code,
duration, and either separate stdout/stderr sections or one combined
section when the provider cannot separate streams.
Session-bound dispatch also emits a typed agent.tool.process.completed
event carrying the process metadata, streams_separated, and bounded
redacted output tails. It is subordinate diagnostic data: the following
agent.tool.completed remains the one tool-protocol completion and the
authoritative owner of is_error, so consumers need no new row.
Nonzero, timed-out, and cancelled commands intentionally change from
successful to failed tool results, and PostToolUseFailure replaces
PostToolUse for them. On Docker the agent shell tool now uses the
streaming path's bash -lc supervisor, which terminates the process group
on timeout instead of leaving container-side processes running.
The public shell schema is unchanged and pinned by an exact assertion.

Follow-up cleanup on the profile-builder refactor.
AgentProfileBuilder::build now borrows instead of consuming, removing the
builder.clone().build() dance at all seven call sites. Deletes
with_command_timeouts, which had no caller but its own test, and the
with_summarizer constructors on all three profiles, whose only remaining
caller was each profile's own new().
Replaces the fifth copy of the profile-kind match (guardrails.rs) with the
builder, and swaps the parity matrix's hand-maintained provider list for
Catalog::effective_agent_profile so a new catalog provider cannot silently
skip the matrix. Collapses web_search_provider_test! into a secrets = arm
on provider_test! and uses EnvVars::BRAVE_SEARCH_API_KEY over a literal.
Drops the Brave key from the Ask Fabro session: AskFabroToolAccessPolicy
denies web_search, and both tools() and the prompt are filtered through
that policy, so the vault read only registered an uncallable tool.
Makes NativeToolOptions::for_profile match exhaustively so a new profile
kind must state its timeout, restores Anthropic's borrowed prompt sections
and Gemini's static prompt (placeholder substitution rather than format!
over 110 lines with doubled braces), and introduces WEB_SEARCH_TOOL_NAME
for the registry lookups that keep tool availability and prompt guidance
in sync.
Updates the product docs, which still described web_search as always
registered and as erroring at call time when unconfigured.
