//! Flag (M5b spec, section 6.3): text shaped like an attack. A flag never refuses: memory keeps the
//! text, one tier lower and marked untrusted. So a rule may be a little broad, but it must match
//! attack behaviour, not bossy English, and the code-work corpus in
//! `tests/sanitize_flag_corpus.rs` holds it to that.
//!
//! The first seven rules are ported from Hermes Agent's strict threat patterns,
//! `tools/threat_patterns.py`, read at commit d0288be5b3330d2442e3907185b8e9d0958297bb
//! (2026-09-26; the file last changed in 1b50e99), https://github.com/NousResearch/hermes-agent,
//! Copyright (c) 2025 Nous Research, MIT License. The eighth is M5a's six instruction phrases,
//! which `memoryd` refused and which flag from M5b on.
//!
//! **The translation.** Hermes matches regular expressions on NFKC text; Boxmaker has no regex
//! crate, so each pattern is written as a sequence of `Part`s matched against the words of the
//! `normalise`d text (split at its single spaces). Hermes' `_FILLER`, up to eight `\w+` words, is
//! `Filler(FILLER)`; its `[^\n]{0,N}` gaps are `Gap(LINE)`. `normalise` joins lines, so a gap is
//! bounded in words instead, and does not cross the end of a sentence or of a shell command
//! (`&&`, `||`, `|`). A keyword is a whole word, punctuation around it aside, where Hermes'
//! keywords also matched inside longer words (its `\badd\b` matched in `ssh-add`), which code is
//! full of.
//!
//! **Not ported**, and why (Hermes' pattern ids):
//! - `html_comment_injection`, `hidden_div`: HTML comments and styles are ordinary code.
//! - `translate_execute`: "translate the parser into Rust and run the tests" is a coding task.
//! - `deception_hide`: "do not tell the user whether the email exists" is advice about auth code.
//! - `role_hijack`, `role_pretend`, `leak_system_prompt`, `remove_filters`, `fake_update`,
//! `identity_override`: role-play and prompt vocabulary; a harness's own notes use it.
//! - The C2 group (`c2_*`, `forced_action`, `anti_forensic_*`, `env_var_unset_agent`,
//! `known_c2_framework`): heartbeats, tasks, nodes and `unset OPENAI_API_KEY` are ordinary in
//! distributed code and its how-tos; Hermes itself only warns on them.
//! - `exfil_curl`, `exfil_wget`, `read_secrets`: `curl -H "…$TOKEN" https://api…` and
//! `cat .env.example` are how every API and project README reads; `exfil-url` keeps the attack.
//! - `hermes_env`, `hermes_config_mod`: Hermes' own paths.
//! - `agent_config_mod` (editing `AGENTS.md`, `CLAUDE.md`, `.cursorrules`, `.clinerules`):
//! Boxmaker's agent never loads those files as its own instructions (its identity is `memoryd`'s
//! files), so the rule would protect nothing here, and it fires on ordinary notes about code.
//! - `hardcoded_secret`: secrets are refused by their prefixes (6.1); a `password = "…"` in code
//! is test data far more often.
