Adds `!secure` as a post-auth chat command dispatched before any agent
sees the message. Subcommands:
- `!secure set NAME=value` — stores the secret in fnox and replies
with "Stored `NAME`" + a retention-warning. Never echoes the value.
- `!secure list` — lists stored secret names (not values). Parses
fnox's output defensively; extra columns that look like values are
stripped before replying.
- `!secure help` / `!secure` — usage string.
Dispatch model (matches existing `!switch`/`!sessions`/`!default`):
- `CommandHandler::is_secure_command(&str)` — static, case-insensitive.
- `CommandHandler::handle_secure(text, identity_id) -> String` —
async (shells out to fnox), takes identity for future per-identity
audit/ACL though not used yet. Wired into telegram.rs in both
`handle_message_nonblocking` and `handle_message` paths, and added
to the unknown-command exclusion list so `!secure` doesn't get
intercepted as unknown before hitting the post-auth handler.
Subprocess approach today — `Command::new("fnox").args(["set", …])`.
Acknowledged-cost: three places now shell out to fnox (vault.rs,
secure_set, secure_list), which means three places that need an
availability check. **Follow-up PR (in flight) will migrate all three
to the fnox library crate via `fnox = { git = "https://github.com/jdx/fnox" }`**
— fnox already exposes public modules (secret_resolver, commands,
etc.) at `src/lib.rs`, so no upstream PR is needed.
Redaction discipline:
- The success reply names the stored secret but never echoes the
value; tested.
- The failure reply surfaces fnox's stderr (user needs to know why
it failed) but doesn't carry the value; tested.
- The telegram channel's `debug!` logs only that a !secure command
was handled, without the message text. A `!secure set FOO=bar`
would otherwise leak the value into ops logs.
- Name validation: `[A-Za-z0-9_-]+` only (matches the substitution
engine's accepted ref-name syntax — so a stored secret can be
immediately referenced as `{{secret:NAME}}` without a rename).
Tested with three invalid-char cases.
5 given/when/then behavioral tests:
- `secure_set_reply_includes_name_but_not_value`
- `secure_set_surfaces_fnox_error_without_echoing_value`
- `secure_unknown_subcommand_returns_help`
- `secure_set_rejects_invalid_name_chars`
- `secure_list_returns_names_only`
All use a fake-fnox shell script installed on PATH via TempDir, so
the tests are hermetic regardless of whether the real fnox is
installed on the dev/CI machine.
Explicit non-goals for this PR (follow-ups):
- `!secure remove NAME` — pending a decision on whether fnox's
own remove command or a config-file edit is the right approach.
- `!secure request NAME` — the out-of-band localhost-paste flow
that avoids chat-transport retention entirely (see
docs/rfcs/agent-secret-gateway.md §5).
- Matrix/WhatsApp channel wiring — same pattern as telegram, but
adds separate verification surface. Doing in a follow-up to keep
this PR reviewable.
- Library-based fnox integration (swap subprocess → lib calls) —
committed as next PR per user direction.

Mirror of the Telegram (PR #20) and Matrix (PR #28) wiring — WhatsApp users can now run !secure set/list/help. Same redaction discipline: never log the message body, never echo value in reply. 3-line change in \`channels/whatsapp.rs\`: 1. Add \`!is_secure_command(&text)\` to the unknown-command exclusion 2. New post-auth dispatch block calling \`handle_secure\` with reply spawned as a tokio task (matches the existing pattern for long-running commands) 3. \`debug!\` log says command handled, no body Stacks on PR #20. This completes the !secure command for the three channels we run today (Telegram + Matrix + WhatsApp). Any future channel adapter (Signal, etc.) follows the same 3-step recipe.

handle_secure parses the subcommand via trimmed.splitn(3, ' '), which treats consecutive spaces as empty tokens. For example, !secure set NAME=value can yield an empty sub and fall back to help instead of running set. Consider parsing the command words with split_whitespace() (similar to handle_switch/handle_model) while still preserving the remainder for the set payload.

secure_set passes the secret value as a command-line argument (fnox set <name> <value>). On many systems, process arguments can be observed by other local users (e.g., via ps/proc), which undermines the goal of keeping secrets from being exposed. Prefer passing the value via stdin or an env var if fnox supports it, or switch to the fnox library API to avoid putting secrets in argv.

The comment says to “bail to a raw echo if the output isn't lines-of-tokens”, but the implementation always tokenizes and never falls back to a raw echo. Either implement the described fallback behavior or adjust the comment to match what the code actually does.

The tests wrap std::env::set_var / remove_var in unsafe {} blocks. If these functions are still safe on the toolchain used in CI, this will trigger an unused_unsafe warning, and CI fails due to cargo clippy ... -D warnings. Consider removing the unsafe blocks (keeping the mutex for serialization), or explicitly allowing unused_unsafe if the project intentionally keeps the blocks for compatibility with a newer std API.

This block says !secure runs post-auth “so we can audit who set what”, but the current handle_secure implementation ignores identity_id (it’s _identity_id) and doesn’t emit any audit record. Either remove/update this claim or implement an audit trail that records the identity and secret name without logging the value.

Codex integration sweep: addressed in #38 without editing this PR branch. The integrated !secure set/list paths log the authenticated identity and secret name/operation while still never logging or echoing secret values.
Cross-cutting triage finding (PRs #20, #21, #23, #26, #28, #31): the !secure parser used `splitn(' ')` which mis-shapes multi-space input — `"!secure set NAME=v"` parsed as sub="" rest="set NAME=v", silently routing through the unknown-subcommand path with the secret in the help-error message. Switch to `split_whitespace()`. Also wires the previously-unused `identity_id` into an audit log so the `_` prefix can drop. The log records identity + subcommand, never the value (`rest`). Closes the "audit-claim docstring with no audit implementation" finding from triage.
