Step 2 showed exactly the named failures: `sanitize_report` failed to compile (one E0432 `unresolved import bxctl::sanitize`, two E0599 `no variant named SanitizeCheck`) and `sanitize_check` failed its 8 tests (each run printed the usage text and exited 2 where 0 or 1 was wanted). Made the edits in order: L1 `pub mod sanitize;` between `memory` and `verify` in lib.rs; C1 appended the `bxctl sanitize check` USAGE block (the memory line lost its closing `";`); C2 the `SanitizeCheck { text: Option }` variant after `Memory`; C3 the `"sanitize" => crate::sanitize::parse_sanitize(rest)` arm in `parse`; M1 `Read` added to the `use std::io` list; M2 the `Command::SanitizeCheck { text }` arm in `main`; M3 the `cmd_sanitize_check` function (argument or stdin read to a String, `bxctl::sanitize::run`, Ok(false)->0 / Ok(true)->1 / Err->2). Filled the five functions in the given order, each from its comment and `cargo check` after: `parse_sanitize` (one `match` with slice patterns and `check == "check"` guards, `[check]` -> `text: None`, `[check, text]` -> `Some(text.clone())`, else `UsageError`); `code_point` (`text.get(at..).and_then(|rest| rest.chars().next())`, `format!("U+{:04X}", u32::from(c))` or `"…"`); `token` (`TAGS.iter().find` the first tag the rest starts with, `format!("token {}", tag.id)` or `"…"`); `prefix` (`PREFIXES.iter().find` the first the rest starts with, `.copied().unwrap_or_default()`); `tag_count` (`TAGS.iter().map(|tag| text.matches(tag.text).count()).sum()`). `cargo fmt --all`; `cargo check -p bxctl` clean; `sanitize_report` 10 passed, `sanitize_check` 8 passed, every bxctl suite passes. `git diff --stat -- crates/bxcore '*Cargo.toml'` prints nothing. `make gate` printed `gate: ok` with 1099 tests (1081 before this task, plus 8 in `sanitize_check.rs` and 10 in `sanitize_report.rs`); `cargo test --workspace` reports 1098 passed plus the gate's separate loopd `end_to_end` ignored test = 1099. No new dependency, so `Cargo.lock` is unchanged. | ornith-1.5-35b-a3b | | M5b/10-gatewayd-links | 2026-09-27 | done | 1 | pass | none | Copied the two skeletons `crates/gatewayd/src/links/mod.rs` (fill 7 functions) and `crates/gatewayd/src/links/inline.rs` (fill 9) and the tests `crates/gatewayd/tests/links.rs`, `links_marked.rs`, `deliver_links.rs` from `docs/plans/M5b/files/`. Filled the nine inline functions in the given order from each comment: `autolink_len`, `definition`, `url_len` (walk `rest.get(..end)` for the trailing run), `construct_len` (reference path was off by one — `reference_end`/`paren_end` return the closing-char index, so the label path needs `label_end + 2` to go through the `]`, matching the paren path), `bracket_end` (count `[`/`]` with backslash skip and code-span run jump), and the five that follow. Filled the seven mod functions (`wrap`, `text`, `code` and the rest of the `Out` type). Fixed the one filled helper the task flagged (`Out::wrap`): after a `\r\n` the `\n` was written a second time, so consume it in `wrap`'s BREAKS arm. `cargo fmt --all`; `cargo check -p gatewayd` clean; every gatewayd suite passes (`links` 7, `links_marked` 7, `deliver_links` 9). First `make gate` run failed on six clippy warnings denied by `-D warnings`, all inside `todo!()` bodies (allowed to edit): a collapsible `if { if let }` in `construct_len`, a `match { Some => c, None => return None }` replaced with `?` in `bracket_end`, a `while let` loop in `url_len`, a manual assign in `bracket_end`, and two needless borrows `self.code(&construct...)` in `Out::wrap`; fixed each. `make gate` printed `gate: ok` with 1081 tests (1058 before this task, plus 7 in `links.rs`, 7 in `links_marked.rs` and 9 in `deliver_links.rs`). `git diff HEAD~1 --stat` lists only the allowed files.

Step 2 showed exactly the named failures: `strict::envelopes_reject_unknown_keys_at_every_depth` failing on `turn_done.json: fixture must decode`, and 13 non-compiling test targets (`turn_wire` in bxcore, `broker` in brokerd, `turn_done_untrusted` in loopd, `admin`/`chat`/`chat_approvals` in bxctl, `deliver`/`deliver_notice`/`serve`/`serve_answers`/`serve_approvals`/`serve_redirect`/`serve_restart` in gatewayd) with E0560 and one E0609. Made the three edits exactly as the task gives: W1 `TurnDone` gains `untrusted: bool` as the last field with the no-default comment in `bxcore/src/wire.rs`; S1 `Session::untrusted` scanning `self.records` for a `LogRecord::ToolResult { untrusted: true, .. }` placed before `last_usage` in `session.rs`; C1 `session.untrusted()` put in the `TurnDone` in `channel.rs` `handle` after `usage`. `cargo fmt --all`; `cargo check -p loopd` clean; the seven `turn_wire` tests and six `turn_done_untrusted` tests pass, and every suite in `bxcore`, `loopd`, `brokerd`, `bxctl` and `gatewayd` passes. `git diff --stat -- crates/gatewayd/src crates/bxctl/src crates/brokerd/src` prints nothing, and the only `serde(default)` in `wire.rs` is line 109, the `Denied` detail added by task 01. `make gate` printed `gate: ok` with 1058 tests (1050 before this task, plus the 8 new: two in `turn_wire.rs`, six in `turn_done_untrusted.rs`).

Step 2 showed exactly the four named failures (`selftest`: three steps without `"tags tokenize as recorded"`; `a_completion_without_the_tool_call_fails_the_tool_call_check` left 2 right 3; `a_cold_second_turn_fails_the_cache_check` left 3 right 4; `serve_runs_the_self_test_then_binds_the_socket_with_mode_0600` left 0 right 66) and `selftest_tags.rs` failing to compile with 7 E0599s (no `TagNotOneToken`/`TagOtherId`/`NeutralisedTooFew`/`Tokenize` variant, no `pointer`). Appended `runbook-loopd-tags-unexpected.md`; `check-runbook.sh` printed nothing and exited 0, `grep -c '^## loopd-tags-unexpected$'` printed 1. Made the edits in order: I1 the private `TokenIds` struct before `CacheOutcome` and I2 the `pub token_ids` method after `tokenize` (left `tokenize` itself unchanged); S1 the `use bxcore::sanitize::{TAGS, Tag, neutralise}` import, S2 the four tag variants plus `SelfTestError::pointer` with each pointer written whole, S3 the four Display arms, S4 the second check `tags tokenize as recorded`, S5 the `tags_tokenize` and `check_tag` functions, S6 check 3 to check 4; M1 `e.pointer()` in `run_selftest_check`. `cargo fmt --all`; `cargo check -p loopd` clean; `selftest_tags` 8, `selftest` 6, `serve` 3, `pointers` 7 passed, every `loopd` suite passes. `grep -rn 'runbook.md#loopd-' crates/loopd/src` prints exactly two lines, both in `selftest.rs`. `make gate` printed `gate: ok` with 1050 tests (1042 before this task, plus the 8 in `selftest_tags.rs`).
