From 824e0940c0f753ba531873c67cd3d69443fe2297 Mon Sep 17 00:00:00 2001 From: macanderson Date: Sun, 26 Jul 2026 10:18:30 -0700 Subject: [PATCH 1/7] =?UTF-8?q?fix(ci):=20unbreak=20main=20=E2=80=94=20fin?= =?UTF-8?q?ish=20#707's=20supersession=20of=20the=20rival=20prune=20engine?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `main` has been red since a69dfd95 (7 commits). Four independent failures were stacked, and only the first was visible: `check-file-size.sh` runs before the Rust toolchain is even installed, so fmt/clippy/doc/test never executed and the three compile/doc breaks behind it went unreported. 1. **file-size ratchet.** 13 grandfathered files grew past their recorded ceilings without the baseline being regenerated. Fixed the way the script itself prescribes — `make file-size-update`. No entry added, none obsolete; still 32 grandfathered files. 2. **`stella-store` did not compile (8 errors).** #704 and #707 independently implemented #616's `store.db` retention. #704 landed `stella-store/src/retention.rs` + `retention_tests.rs` + `stella-cli/src/storage_prune.rs` (`stella storage prune`); #707 landed `stella-store/src/prune.rs` + `stella stats prune`. #707's engine won and swapped `pub mod retention;` for `pub mod prune;` in lib.rs — but left #704's two *consumers* wired up, so `retention.rs` became an orphan outside the module tree while `mod retention_tests;` and `mod storage_prune;` kept importing `crate::retention`. `prune.rs` is unambiguously the survivor: `AGENTS.md` documents `stella stats prune` with exactly its semantics, it has an end-to-end witness in `stella-cli/tests/stats_prune_cli.rs`, and it is cross-referenced from `stella-store/src/lib.rs`, `usage.rs`, and `usage_cmd.rs`. The `retention` path cited no issue and was referenced only by its own files. So this completes the supersession rather than reviving the loser: the three files and their `main.rs` wiring are deleted. 3. **`cargo doc -D warnings` failed in `stella-store`.** prune.rs's module docs intra-doc-linked `dependent_tables_cover_every_execution_keyed_table`, which is `#[cfg(test)]` and so unresolvable when rustdoc builds without test cfg. Named in backticks instead, with a note saying why it is not a link. 4. **`cargo doc -D warnings` failed in `stella-tools`.** A redundant explicit link target in policy.rs (`[`catalog::group_for`](crate::catalog::group_for)` — label and target resolve identically). Collapsed to the plain path form. Two behavioural notes, deliberate in #707 and made permanent by dropping #704's tests, called out because they are easy to miss in a red-main repair: unfinished (in-flight) executions are no longer protected from pruning — prune.rs argues a NULL `finished_at` is exactly the debris retention should reclaim — and a pending enterprise export no longer holds an execution back; the export ledger is instead excluded from the cascade outright, since `executions.id` is AUTOINCREMENT and ids are never reused. Verified locally: check-no-scratch, check-action-pins, check-file-size, `cargo fmt --check`, `cargo clippy --workspace --all-targets -D warnings`, and `RUSTDOCFLAGS=-D warnings cargo doc --workspace --no-deps` all pass. --- CHANGELOG.md | 10 + docs/design/threat-model.md | 2 +- scripts/file-size-baseline.txt | 26 +- stella-cli/src/main.rs | 13 - stella-cli/src/storage_prune.rs | 149 ----------- stella-store/src/lib.rs | 2 - stella-store/src/prune.rs | 5 +- stella-store/src/retention.rs | 304 --------------------- stella-store/src/retention_tests.rs | 397 ---------------------------- stella-tools/src/policy.rs | 2 +- 10 files changed, 28 insertions(+), 882 deletions(-) delete mode 100644 stella-cli/src/storage_prune.rs delete mode 100644 stella-store/src/retention.rs delete mode 100644 stella-store/src/retention_tests.rs diff --git a/CHANGELOG.md b/CHANGELOG.md index 837f3865..2547c9e0 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -26,6 +26,16 @@ record of *changes*, curated by the person who made them. ## [Unreleased] +### Removed + +- `stella storage prune` — superseded by `stella stats prune`, which is the + `store.db` retention path documented in `AGENTS.md` and covered end-to-end by + `stella-cli/tests/stats_prune_cli.rs`.

Same syntax operators already type; it just stops hardcoding two keys. Covers MCP (`mcp`) and customer-registered tools (`custom`) too. - `PolicyToolSet` enforces it directly below `DiscoveryToolSet` — above MCP, custom, and interactive — so `tool_search` cannot advertise a withheld tool. It filters `schemas()` AND refuses `execute()`: hiding is a prompt-budget measure, gating is a capability boundary, and the two must not be confused. - `candidate_ws.rs` gets it too. Best-of-N candidates build their own registry from the same options, so post-flip they were a bypass. - `stella tools` names the key that withheld each tool instead of two hardcoded "disabled (default)" blocks. The managed ceiling needed more than union-of-denials, which the witnesses caught: a managed `{"process": "off"}` is a group key and a project `{"start_process": "on"}` is more specific, so the union left the org's denial standing while the tool ran anyway. `apply_tool_ceiling` now also drops any merged grant the ceiling would deny. Witnesses verified against the old code in a detached worktree — six fail there, including `bash_is_registered_with_no_options_at_all` (the flip itself) and four proving the old `ToolsSettings` silently dropped any key that was not `bash`/`web`. Stated honestly: `{"bash":"off"}` hiding-and-refusing is a regression pin, not a fail-on-old witness — bash was absent by default before too. Its group and custom-tool siblings are the discriminating ones.

From adb86ee9cb395bebbe194e79bcf4a8a66c9c99c5 Mon Sep 17 00:00:00 2001 From: macanderson Date: Sun, 26 Jul 2026 11:03:40 -0700 Subject: [PATCH 3/7] feat(tui): a tools on/off editor in the SETTINGS tab MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The settings surface for the tool policy. `views/settings.rs` said "as more config surfaces move here they become sections of this tab" — this is the second section. The deck had no tool list at all, so one now flows from the driver. The catalog alone would not do: MCP tools and customer-registered custom tools only exist at runtime, and being able to switch off your own tools is the point. The driver sources from the live base executor + custom tools + the catalog's session set, and re-derives the effective policy from disk on every refresh — `cfg.tool_policy` is frozen at session start, so reading it would have made a save invisible until restart. Rows are grouped by catalog group, with `mcp` and `custom` as ordinary sections so a customer sees their own tools by name. Each row names the key and the scope that switched it off. Keys are `engine.rs`'s vocabulary verbatim — `space`/`⏎` toggle, `x` clear, `s`/`S` save user/project, `r` reload, `Esc` release — with `t` to focus, mirroring `e`. Org-managed denials render locked and refuse to toggle, and the *writer* refuses a grant the ceiling denies. Both halves, because a UI that offers a switch which silently will not work misrepresents the posture. Two details worth naming: - `ToolRow` has no `enabled` field. On/off is derived from the switches plus unsaved edits, so there is one answer rather than two that can drift. The resolver checks the pending edit at each precedence level before the saved switch, so a pending *group* grant cannot outrank a saved *exact* denial — the naive "edits first, then base" version gets that backwards. - `ToolsSettings::save_to` mirrors `AgentEngineConfig::save_to`: read as a `Value`, replace only `"tools"`, symlink-reject, 0600 for user scope. An emptied section removes the key rather than writing `{}`. The panel sends only changed keys and the driver read-modify-writes, so saving to one scope cannot copy another scope's switches into it. Attribution needed more than `disabled_by()`: that yields the key, but the *scope* is unrecoverable from the merged policy — merging is what destroys it. Hence `Settings::load_tool_scopes` / `ToolScopePolicies`, which also exposes `managed_tool_ceiling()` outside the settings module for the first time. Witnesses are by mutation, since every surface here is new: each named test was confirmed to flip red when the behaviour it pins is removed (the lock short-circuit, the exact-vs-group key choice, the key-preserving write, the writer's ceiling refusal, the tab rendering the panel). That pass caught a weak witness of its own — `toggling_a_tool_writes_its_exact_name_never_its_group` originally toggled `bash`, whose group is also `bash`, so it could not tell the two keys apart; it now toggles `start_process` and asserts `send_stdin` is untouched. Rendering was verified by drawing the real deck into a `TestBackend` at 160x30 and 90x30, focused and unfocused, with a pending group edit and a locked row. That found one defect: a truncated MCP name ran into the state column. The snapshot test writes its frame to `$CARGO_TARGET_TMPDIR` so it stays inspectable. Also moves `mod tool_policy;` to `main.rs`, closing the in-repo FOLLOW-UP the previous commit left behind.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit fixes the issue reported at stella-cli/src/agent.rs:2058 ## Bug In `stella-cli/src/agent.rs`, `run_turn` branches on `process_free_authority_active()`: ```rust let outcome = if crate::enterprise_telemetry::process_free_authority_active() { let engine = Engine::with_sleeper(provider, registry, engine_config_for(cfg), &TokioSleeper) .with_calibration(calibration); engine.run_turn_with_sender(messages, budget, &tx).await } else { // ... builds CustomToolSet -> InteractiveToolSet -> PolicyToolSet -> DiscoveryToolSet let permitted = PolicyToolSet::new(&interactive, session_tool_policy(cfg)); ... }; ``` The process-free branch hands the raw `registry` (`&ToolRegistry`) straight to the engine, **never** wrapping it in `PolicyToolSet`. The `else` branch does apply `PolicyToolSet::new(&interactive, session_tool_policy(cfg))`. ### Concrete trigger `run_turn` is invoked from the interactive REPL loop and from `run_raw_one_shot` (`--no-pipeline`). In process-free mode, `ToolRegistry` still registers many non-host tools (`read_file`, `write_file`, `edit_file`, `apply_edits`, `delete_file`, `save_memory`, task tools, `generate_svg`, etc. — only the host-reaching class is withheld at construction). So with an operator/managed-org policy such as: ```json { "tools": { "write_file": "off" } } ``` or ```json { "tools": { "*": "off", "read_file": "on" } } ``` the model can **still** call the disabled tools on this path, because no `PolicyToolSet` gates them. Every other driver path (`pipeline` in `agent/goal.rs`, `command_deck.rs`, `subsession.rs`, `fleet_cmd.rs`, `run_pipeline_one_shot`) applies `PolicyToolSet` unconditionally — this was the only path with the gap, breaking the stated invariant that the policy sits above the whole session tool stack on every path. ## Fix Wrap `registry` in `PolicyToolSet::new(registry, session_tool_policy(cfg))` in the process-free branch before handing it to the engine, mirroring the other paths: ```rust let permitted = PolicyToolSet::new(registry, session_tool_policy(cfg)); let engine = Engine::with_sleeper(provider, &permitted, engine_config_for(cfg), &TokioSleeper) .with_calibration(calibration); engine.run_turn_with_sender(messages, budget, &tx).await ``` This is type-safe: `&ToolRegistry` already coerces to `&dyn ToolExecutor` (it was passed directly to `Engine::with_sleeper`), which is what `PolicyToolSet::new` accepts, and `&PolicyToolSet` implements `ToolExecutor` (it is wrapped by `DiscoveryToolSet` in the `else` branch). `PolicyToolSet` and `session_tool_policy` are already imported/used in the same function. The process-free layer intentionally strips MCP/custom/interactive/discovery layers, but policy enforcement is preserved.

As on main, `check-file-size.sh` runs before the Rust toolchain installs, so the fast fail hid a genuine compile error behind it. Three fixes: 1. **`stella-cli/src/settings.rs` crossed the 1500-line ratchet at 1623 lines.** It is not grandfathered, and the guard hard-blocks that case while explicitly forbidding a baseline entry — "the baseline only covers files that predate the guard, and this is the rule that stops the tree getting worse." So it is split, not exempted: the 868-line `#[cfg(test)] mod tests` moves to `stella-cli/src/settings/tests.rs`. That directory already holds seven sibling modules, and the same split has precedent in e72b02f0 (deck_ui.rs) and in stella-store's `*_tests.rs` files. settings.rs drops to 756 lines, the new file is 874 — neither needs an entry. Pure move, verified as such: the extracted body is byte-identical to the old inline body modulo one dedent level, all 27 `#[test]`s are still present, and `cargo fmt --check` passes on the result untouched. `use super::*` resolves to `crate::settings` from a file submodule exactly as it did inline, so nothing about name resolution changes. 2. **`StorageCmd::Prune(_)` was missing from `run_storage`'s match** — `error[E0004]: non-exhaustive patterns`. The merge commit 6e612078 kept the variant and its early-return dispatch but dropped the `unreachable!` arm. `origin/main` still has that arm (main.rs:1305) and main is green, so this was introduced by this branch's conflict resolution, not inherited. Restored. 3. **Four grandfathered files grew** — agent_tests.rs +157, agent.rs +32, candidate_ws.rs +24, command_deck.rs +1 — so the baseline is regenerated per the script's own instruction. It also *tightened* five ceilings where this branch shrank files (registry.rs 3052→3014, main.rs, stella-store/lib.rs, media.rs, and one more), so the ratchet moves net-inward. Still 32 entries.

Six grandfathered files were still over ceiling. Regenerated against the actual tree; the raises this branch really owes are now visible, per the guard's own rule: command_deck.rs 4465→4592 (+127) the `tools` section: `handle_tools_input` and `tool_policy_inbound`, beside their inline sibling `handle_engine_config_input` deck_ui.rs 3940→3965 (+25) tools panel state on the deck agent.rs 2223→2224 (+1) the process-free `PolicyToolSet` wrap main.rs 1776→1782 (+6) the Prune arm's fuller comment engine.rs 1650→1652 (+2) `t` alongside `e` in the key row deck_render.rs 1670→1671 (+1) command_deck.rs's +127 is the one worth a reviewer's eye. It is left inline deliberately: `handle_tools_input` is the exact structural peer of `handle_engine_config_input` directly above it, and hoisting only the newer of the two into a submodule would split a matched pair to satisfy a counter. 2. **`StorageCmd::Prune(_)` was duplicated, not missing** — `warning: unreachable pattern`, which `-D warnings` makes fatal. #717 read the merge as having *dropped* main's last-position arm, but the merge had *moved* it to the top of the match with a fuller comment, so re-adding it made two. Removed the re-added copy; the branch's own better-documented arm at the head stands. 3. **`views/settings.rs` intra-doc-links private `SPLIT_MIN_WIDTH`** — `-D rustdoc::private_intra_doc_links` fails the doc build. The prose only names the threshold, so it drops to plain code formatting rather than widen the constant's visibility for a comment's sake.
