The **only** +difference from a model `read_file` call is that the human typing `@path` **replaces the `confirmAction` +prompt** โ€” a person naming a path at their own prompt is a stronger, more specific consent signal than +answering `[y]` to a model-chosen path. Consent replaces the *prompt*; it **never** relaxes the confidentiality +floor, the binary fail-close, or the size cap โ€” that is what closes attack (1). Further: + +- **Injected bytes are USER-position, untrusted content.** The snapshot is spliced into the user message at + compose time, never the system / instruction position; a `secret`-typed value is still never interpolated + ([ADR-0029](0029-tool-policy-hardening.md)), and any `--json` / observability field passes + `redactSecretShapedText` ([ADR-0029](0029-tool-policy-hardening.md)(c), the one redaction primitive). +- **First-class, directory-navigable completion.** Typing `@` opens a Tab-completion overlay that lists **both + directories** (navigable โ€” selecting one descends into it) and **files** (selecting one injects it), so the + affordance matches and exceeds the competitor `@`-mention UX. `.gitignore` / `.relavium` honoring is + **advisory** โ€” it only trims noise (`node_modules`, dot-dirs) from the **candidate list**, enforced with an + **in-house, ReDoS-safe** matcher (no new `ignore` dependency, per [CLAUDE.md](../../CLAUDE.md) #2). It is + **not** the security boundary: the confidentiality floor above refuses a sensitive path *regardless* of + whether an ignore rule happens to cover it, so a non-ignored `.env` cannot leak on the theory that "ignore + would have caught it." (Directory / glob **expansion** โ€” `@src/`, `@**/*.ts` injecting many files โ€” is a + deferred follow-up, [deferred-tasks.md](../roadmap/deferred-tasks.md); 2.5.D ships single-file injection with + full directory *navigation* in the picker.) +- **Binary fail-close + a byte-heuristic token warning.** A NUL-probe refuses binary content (media input, D12, + is a separate security-reviewed follow-up โ€” [chat-session.md](../reference/cli/chat-session.md)); the + token-limit warning is a **byte heuristic** (`utf8ByteLength`, ~4 bytes/token), **no tokenizer and no new + dependency**. + +*Considered:* a raw `node:fs` read for speed (rejected โ€” reopens attack (1), bypasses the floor); a friendlier +dedicated "user-context" scope broader than the fs tier (rejected โ€” relaxes the confidentiality floor the whole +point is to keep); making `.gitignore` the boundary (rejected โ€” ignore is UX, not security; a non-ignored +secret would leak). + +### `!`-shell routes through the one `run_command` boundary via an additive `AgentSession` method + +`!command` is dispatched as a **user-initiated `run_command`** through the **exact** boundary a model tool call +uses โ€” `enforcePolicy(allowedCommands)` (exact-match, enforced **before** the approval floor) โ†’ the mode-aware +`confirmAction` gate โ†’ the hardened process arm (`shell:false`, ambient-PATH resolution, the declared-env +denylist, a workspace-jailed cwd, bounded output buffers, process-group `SIGKILL`) +([ADR-0055](0055-cli-host-capability-seam-tool-environment-factory.md), [ADR-0057](0057-cli-chat-modes-and-per-tool-approval.md)). +The execution vehicle is a **new, additive `AgentSession.runUserCommand()`** that **reuses `#runTurn`'s +dispatch-context construction verbatim** โ€” the approval regime (`confirmAction`), the `toolPolicy`, the +`fsScope`, and `gateApproved: false` โ€” **never a dispatch context re-assembled in `apps/cli`**.

The floor is unchanged: `enforcePolicy` matches the allowlist **before** + `confirmAction`, so no mode (`auto` included) runs a command outside it. Editing chat `allowedCommands` is a + [security-review.md](../standards/security-review.md) trigger; the curated default set is itself part of the + reviewed surface and lands under that trigger. +- **Output is injected as untrusted, pending context.** `!cmd` stdout/stderr is buffered as **pending context + that rides the next `sendMessage`** (not an immediate model turn โ€” no per-`!` token cost). It carries the + **same untrusted brand** `run_command` output already carries (byte-capped by the bounded buffer, never a + trusted instruction), and is redacted on any observability field. The user sees the output immediately; the + model sees it on the next turn. +- **Non-TTY contract.** With no interactive approver (plain / `--json`), `!`-shell runs only what `auto`-mode + policy + the allowlist already permit and never blocks on a prompt; the [ADR-0049](0049-cli-machine-output-contract.md) + machine-output contract is untouched (`@` / `!` are TTY ergonomics).

ADR-0061 is a **new mechanism at a different layer** โ€” the `apps/cli` **input line** โ€” +so it is a **sibling ADR, not an amendment** to either (per the [README](README.md) convention: a new mechanism +gets its own ADR). Its whole job is to guarantee that the two input-layer features **re-enter** those audited +boundaries rather than bypass them: `@`-mention reuses ADR-0055's `fs` read jail; `!`-shell reuses ADR-0055's +`process` arm + ADR-0057's `confirmAction` floor via the additive `runUserCommand`.

Migrate BOTH input owners (ChatApp's editor/editorRef ref-shadow and the Home controller's state.input) so they stay in lockstep on the one shared reducer; the coalesced-chunk op-not-value functional fold is preserved (edit ops still fold over the accumulated EditorState). dropLastCodePoint stays (reused by deleteBeforeCursor + the palette query).

Fixed: - SECURITY (MEDIUM): Ctrl+A (newly a line-start motion) collided with the approval approve-always intercept โ€” reduceApprovalKey matched char==='a' with no ctrl/meta guard, so a stray Ctrl+A during a pending approval silently selected the persistent, most-permissive approve-always, subverting the ADR-0057 fail-closed floor. Now only an UNMODIFIED letter answers (Ctrl+A/Ctrl+Y/Ctrl+N are swallowed); digit shortcuts stay unconditional. - BUG (MEDIUM): lineStart used lastIndexOf('\n', i-1); at cursor 0, lastIndexOf(-1) clamps to 0 and false-matched a LEADING newline โ†’ Home/Ctrl+A jumped past the empty first line and Ctrl+U inverted its cut range, corrupting '\nabc' โ†’ '\n\nabc'. Guard i<=0. - LOW: killRange now guards from>=to (not just ===) as defense-in-depth against an inverted range; the Home editor arm no longer bumps doctorRunId / clears a visible /doctor notice on a NO-OP boundary motion (reference-equality gate); a pasted CRLF/bare CR is normalized to LF in the appended text so no stray \r reaches the model/transcript. New regression tests: the approval chord guard, line-start at cursor 0 on a leading-newline buffer, CR normalization, controller-level Home motion/newline/kill dispatch, and the no-op-motion-preserves-notice case. All gates green (1213 tests).

Fixed: - SECURITY (MEDIUM): the approval-prompt DIGIT shortcuts (1/2/3) bypassed the opus-round `bare` guard, so Alt+1/2/3 (meta+digit, reachable via ink's ESC-prefixed parsing) still silently answered a pending approval โ€” the same ADR-0057 fail-closed hole the letter fix closed, left open for digits. reduceApprovalKey now requires `bare` for ALL answers. - BUG (MEDIUM): Ctrl+W (killRange word-back) was not line-scoped โ€” wordLeft treats '\n' as ordinary whitespace, so Ctrl+W on/near a blank line wiped the whole previous line/paragraph in one keystroke. Clamp from = max(wordLeft, lineStart), matching the sibling kills. - BUG (MEDIUM): the Home bracketed-paste path spliced raw content, bypassing the CRLF/CRโ†’LF normalization the same PR added to the keystroke append โ€” a pasted '\r' survived in the buffer + transcript. Normalize the paste payload too (both paths now consistent). - LOW: word class now includes \p{M} so a base letter + combining diacritic is ONE word; the Home handleChatKey edit arm skips re-render on a no-op motion (reference-equality gate, mirroring handleHomeKey); PromptEditor documents its intentional reflow (a live editor must keep the cursor visible โ€” truncating would hide it and break multiline). New tests: Alt+digit approval guard, Ctrl+W line-scoping across newlines, combining-mark word motion, and a promptRows+sanitize split-ESC injection test (no ANSI/OSC survives at any cursor split).

Not persisted across sessions (cross-session history is a tracked follow-up). - Vertical Up/Down: moveCursor gains 'up'/'down' (column-preserving, code-point-snapped, a NO-OP at the top/bottom edge). reduceEditorMotion maps the arrows; the chat callers do a vertical move when possible and fall back to history recall at the edge, so multiline navigation and history coexist. The bare Home gets vertical motion only. - Ctrl+R opens a keyboard-owning reverse-search submode (mirrors the / palette: mutually exclusive with it, yields to a pending approval), rendered by ReverseSearchView (sanitized). Enter loads the matched entry; Esc/Ctrl-C cancels. New tests: the full history + reverse-search model, vertical-motion edge cases, and the in-Home chat Up/Down + Ctrl+R end-to-end. All gates green (1227 tests).

Fixed: - Reverse-search accept did not reset history navigation on EITHER surface, so if the user was mid Up-recall when they opened Ctrl+R, a subsequent Down called historyNext and silently clobbered the just-accepted entry with the stale pre-search draft. Both accept branches now resetHistoryNav (the accepted text becomes the live buffer). - A bracketed PASTE while the in-Home reverse-search submode was open bypassed the search fold and leaked into the hidden input buffer โ€” the paste `editable` gate checked `palette` but not `search`. Added `state.search === undefined` so paste is dropped while search owns the keyboard (mirroring the palette). - A NO-OP edit keystroke (Ctrl+K at line end, backspace at column 0) while recalling history reset the nav (discarding the saved draft) BEFORE the no-op guard on both surfaces; reordered to reset only when the buffer actually changed. - Refining a reverse-search query (typing after Ctrl+R-stepping to an older match) re-anchored to the newest match, yanking the selection forward; a new reverseSearchExtendQuery searches from the current match downward (extend narrows; backspace still widens from newest). New tests: the query-extend anchor + the accept-then-Down no-clobber. All gates green (1229).

Fixed: - HIGH regression (my own opus-round fix): the ChatApp edit case had been changed from a true functional setState updater to a constant `() => next` precomputed from editorRef.current, which is stale until the queued updater flushes โ€” so a coalesced stdin chunk interleaving an edit with a move/history action silently DROPPED keystrokes (the reviewer empirically reproduced a-Left-b-Left-c-Left-d โ†’ "ad"). Restored true functional updaters for the edit, move, and reverse-search-accept cases; the no-op check + the idempotent resetHistoryNav now live INSIDE the updater so the fold is never broken again. - MEDIUM: a multi-character paste while Ctrl+R search is open (the standalone chat has no bracketed-paste latch, so a paste is one multi-char event) corrupted the search query via the catch-all extend. foldReverseSearchKey now extends only on a SINGLE code point, dropping a blob (parity with the Home's paste gate). - LOW (x3, ReverseSearchView first-class polish): add marginTop to match the palette's spacing; add a trailing "Ctrl+R older ยท Enter accept ยท Esc cancel" discoverability hint; render the query bold + the match dimmed with a ` โ†’ ` separator so neither is mistaken for the literal framing. All gates green (1229 tests). (The HIGH is a React-wiring regression; the repo has no ink-render test harness, so the fix restores the documented functional-updater pattern the reducer-level burst tests already validate.)

For the chat surface a declared **Full access** tier is **clamped to Project-scoped** โ€” an unjailed read could exfiltrate `~/.ssh` / `~/.aws/credentials` back to the model, a risk a write-capable chat shares โ€” so it clamps too; `full` stays intact only for the author-trusted workflow-run profile. ## Where tools run From 48dd8ad7f8a819a690726827414cab00f39cfe2c Mon Sep 17 00:00:00 2001 From: Cemil ILIK Date: Fri, 3 Jul 2026 08:17:24 +0300 Subject: [PATCH 15/34] feat(cli): @-mention completion model + fs-jailed reader (2.5.D step 4b-i, ADR-0061) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The pure, tested core of @-mention (the UI wiring lands next): a completion-submode state + foldMentionKey contract (โ†‘/โ†“ select, Enter/Tab/'/' accept โ€” a dir descends, a file injects; backspace trims or drops the '@'; a multi-char paste blob is dropped like the other submodes), and a MentionReader that is a THIN wrapper over the session's SAME FsCapability โ€” so the read/list go through that ONE audited boundary: the jail, the sensitive-read confidentiality floor (the listing-gate skips .ssh/.env/.aws/โ€ฆ โ€” never even offered), the binary fail-close, and the 8 MiB cap are all enforced there, never a raw node:fs read. Plus the injection formatter (untrusted, user-position framing with a tag-safe path) and the ~4-bytes/token size heuristic.

Read-only by construction โ€” the mention path never writes; the listing-gate + confidentiality floor + binary/size guards are enforced by the one audited fs boundary. - `mention.ts`: add a `loading` flag, the `mentionOpensAt` word-boundary open predicate, and a `restore` string on the close step so Esc/no-match restores the literal `@`+filter (nothing typed is eaten) while backspace-past-`@` deletes it. - `chat-ink.tsx` (ChatApp) + `home-controller.ts` (in-Home chat): the async submode owns the keyboard (Esc/โ†‘โ†“/EnterยทTabยท'/'/backspace/filter), opens on `@` at a word boundary, lists through the fs jail (a stale resolve dropped by a dir guard), and on accept-file reads + injects `formatMentionInjection` framed, UNTRUSTED, user-position context at the cursor. A large file adds a soft token-warn note; a read rejection surfaces a static, secret-free note. Paste is dropped while the submode owns the keyboard (parity with palette / reverse-search). `@`/`/`/mention are all TTY-only; a plain/`--json` driver treats a leading `@` as a literal. - `mention-view.tsx`: the completion overlay (windowed scroll around the selection, dirs marked `/`, loading vs no-match hints), every free-form field sanitized at the display boundary. Tests: `@`-flow openโ†’descendโ†’acceptโ†’inject + Esc-restore + mid-word literal in the Home controller; `mentionOpensAt` + the `restore`/`loading` model in mention.test.ts; the pure `mentionWindow` scroll math. 1242 CLI tests green; typecheck/lint/build/format/bundle-closure green; Leakwatch clean.

So the `!`-shell can never diverge from the audited command sandbox โ€” no dispatch context is re-assembled in `apps/cli`. - The user command GRANTS `run_command` for its one-off dispatch (the user typed it โ€” the grant is implicit); this never reaches the model (a direct dispatch, not a turn). The security gate stays the allowlist + confirmAction. - The caller pre-tokenizes the line into `command` + `args` (no shell metachar expansion โ€” `shell:false` spawn). The result is a classified discriminated union `UserCommandOutcome` (`ran` | `denied{allowlist}` | `failed` | `cancelled`) so the host renders each case and no raw error escapes; `denied.allowlist` distinguishes an allowlist miss (โ†’ actionable opt-in hint) from an approval / mode deny. The engine stays pure (no platform import, no vendor type). - Callable only when started + idle (a `!` never races a turn); leaves the session idle + reusable. Config: `[chat].allowed_commands` + `allowed_command_globs` (โ†’ engine camelCase `allowedCommands` / `allowedCommandGlobs`), **empty/absent โ‡’ `!`-shell disabled** (the `empty โ‡’ disabled` symmetry; no chat-specific relaxation). Tests: allowlist miss (denied, no spawn), allowlisted run, glob run, approval reject/approve, spawn-fault โ†’ failed (secret-free), lifecycle guard, reuse; the config schema.

A plain message typed during a slow `!npm test` reached `sendMessage` โ†’ threw `SessionStateError` (session not idle) โ†’ nothing caught it โ†’ the whole chat/Home session CRASHED (losing the just-appended turn). Fix: a `shellBusy` flag on both surfaces (a ref-shadowed local in ChatApp; a `HomeControllerState` field in the Home) โ€” set when a `!`-command starts, cleared in every settle branch (+ on chat end), OR'd into the `isRunning` gate that feeds `reduceChatKey` (so a mid-command keystroke can't reach `sendMessage`) and into the busy indicator + the paste gate. Ctrl-C (cancel) and Esc (abort) still precede the gate, so a stuck command stays interruptible. - LOW: `UserCommandOutcome.ran` dropped the `truncated` flag โ€” it was computed from the discarded model-facing `boundForModel` pass, describing data the caller never receives (the returned stdout/stderr are the process-armโ€“bounded identity `output`, and the host re-bounds + marks truncation on inject). A misleading flag on a security-bearing type; removed rather than half-right. Tests: a regression that a message typed while a `!`-command is in flight is gated (never sent, no onError crash) and the session recovers on resolve. Full gate green; Leakwatch clean.

The Home is opened from `run.ts` (the bare-invocation path), NOT through `dispatch.ts`, so it never received the keychain-backed resolver injection. Fix: default the Home's `providers` + `mcpSecretResolver` to keychain-backed (one shared `createOsKeychainStore()`), mirroring `dispatch.ts`'s `keyResolvers` and matching the Home's existing self-wired production defaults (e.g. `doctorProbes`). `createOsKeychainStore()` reads nothing until a key is resolved, so it is side-effect-free; a test injects `providers` and never reaches the keychain. Regression test: with `providers` NOT injected, the resolver MUST receive the keychain (a two-module mock asserts the wiring end-to-end) โ€” this fails against the old env-only code.

Two-layer root cause: `kindFromHttpStatus(402)` fell through to `unknown`, and `codeForLlmError` maps `unknown` โ†’ `internal`. Classification (all three providers, one point): map 402 โ†’ `auth` in the shared `kindFromHttpStatus`. 402 Payment Required is a fatal account/billing problem (insufficient balance, exhausted quota); the `auth` bucket โ†’ `provider_auth` and is non-retryable (retrying the same provider cannot restore balance). Because the Anthropic, OpenAI/DeepSeek and Gemini adapters all route HTTP status through this one helper, the fix covers every provider. Chat surfacing: the interactive footer previously dropped the message for every code except the two approval-floor labels, so even after reclassification it would show only `error: provider_auth`. Add a separately-justified `PROVIDER_MESSAGE_CODES` set (`provider_auth` / `provider_rate_limit` / `provider_unavailable` / `content_filter`) whose message is a provider-authored status line โ€” already secret-scrubbed at the `makeLlmError` seam choke point and terminal-sanitized at render โ€” so the footer now reads `error: provider_auth โ€” 402 Insufficient Balance`. `tool_failed` stays excluded (its message may carry model/MCP context). The `run`/`--json` path already rendered the message; this only closes the interactive-chat gap. Docs: error-handling.md groups 402 with 401/403 under fatal. Tests: kindFromHttpStatus(402) โ†’ auth (non-retryable); the chat footer renders the provider status message for the provider_* / content_filter codes.

Without these rows an agent naming `deepseek-v4-flash` egressed fine (provider inferred from the id prefix) but fell out of the pricing table, so its cost tracked as $0 (UnknownModelError, best-effort zero); it now prices correctly. The legacy `deepseek-chat` / `deepseek-reasoner` aliases are kept (relabeled "(legacy)", prices unchanged โ€” the pricing page no longer lists them, so they hold the last verified 2026-06-11 values) until they deprecate 2026-07-24 15:59 UTC, so existing agents/configs and the conformance fixture keep working until then. Also: repoint the DeepSeek `provider test` / `/doctor --deep` key-probe testModel from the deprecating `deepseek-chat` to `deepseek-v4-flash`; refresh the DEEPSEEK_SUPPORTS comment (v4-flash / -pro both expose thinking โ€” per-provider capability flags unchanged). Tests assert the two new rows' per-MTok prices; the MODEL_PRICING invariant test auto-covers field completeness for the added keys.

Nits: - input-history: `.at(-1)` for the last entry; optional chain in findMatch. - injection / chat-input: `codePointAt(โ€ฆ) > 0xffff` for surrogate-pair detection (matches the file idiom; charCodeAtโ†’codePointAt); `replaceAll` for the nonce. - mention.ts: re-export the injection bounds/nonce via `export โ€ฆ from`. - mention-view: extract the loading/empty/rows nested ternary into a render fn. - home-controller / chat-ink: flip the `parsed !== undefined` submit if/else to a positive condition; guard-return in loadMentions' applyIfCurrent (drops the `x !== undefined && x.y` optional-chain smell while keeping the narrowing). - agent-session: extract the `#userCommandSeq += 1` assignment from the id template; agent-session.test: assert the reusable-session postcondition loudly. - drive-home.test: type the provider-mock wrapper to the real API (no `as never`). Skipped: (1) the "UserCommandOutcome resolves to any" inline comment โ€” a false positive: the built `.d.ts` carries the full discriminated union and strict typecheck (no-any) passes; the reviewer's IDE resolved a stale/unbuilt core. (2) prompt-view array-index key โ€” the prompt echo is a fully-recomputed, non-reorderable positional line list with no per-line id, so the index is the correct React key.

Repriced to flash. - Broken ADR-0061 relative links (one `../` short): injection.ts / shell.ts / mention.ts / mention-view.tsx (4โ†’5 `../` from tui/, verified vs ink-renderer.ts) and agent-session-spec.md (`../`โ†’`../../decisions/`, verified vs its siblings). - config-spec.md: reconciled the contradictory `[chat]` wording โ€” it now states chat DOES define its own `allowed_commands` / `allowed_command_globs` keys that map to the SAME engine `allowedCommands` policy (not "no own allowlist"). - fs.ts: the sensitive-read denial message now names the full current floor (.aws / .env* / .docker config), not just .ssh/.relavium/git. - mention.ts: `foldMentionBackspace` trims the filter by whole CODE POINT (`dropLastCodePoint`), so backspacing an astral char no longer leaves a lone surrogate (test added).

Nits: - home-controller: split loadMentions' undefined-check onto its own line (narrows `open` for the spread, drops the prefer-optional-chain smell). - prompt-view: key each prompt row by its line START char offset โ€” a stable, positional id (not the array index; identical lines never collide). Tests: `runUserCommand` `cancelled` branch (mid-command cancel โ†’ aborted dispatch โ†’ ToolCancelledError).

Tests: new `injection.test.ts` (frame/sanitize/bound/surrogate), `shellDenyHint` branches, `appendAttachment` dedup+cap, Esc-clears-chips (idle) vs no-op (busy), busy-label, stderr preview; existing inline-injection assertions updated to the chip model. Full `pnpm run ci` green; Leakwatch clean. Docs: ADR-0061 "Refined at implementation" append (append-only), chat-session / home keymap (chips, `Delete` forward-delete, `Esc`).

Root cause: ink 6.8.0 reports the Unix physical Backspace key (DEL, `\x7f`) as `key.delete`, NOT `key.backspace` (its parse-keypress carries an explicit TODO about the split), and a prior 2.5.D change routed `key.delete` to a forward-delete. So pressing Backspace erased the character AFTER the cursor โ€” exactly the reported "arrow-left then delete removes to the right" behavior. Fix: map BOTH `key.backspace` and `key.delete` to delete-before-cursor in `reduceEditorMotion` โ€” the same fold the palette / reverse-search / mention submodes already use (the main editor was the lone inconsistency). The true forward-Delete key (`\x1b[3~`) is also reported as `key.delete` and is indistinguishable at ink's useInput layer (both yield input='' + key.delete), so a reliable forward-delete binding isn't achievable; removed the non-functional forward-delete machinery (the `{kind:'delete'}` action, `deleteAfterCursor`, and its `case 'delete'` handlers) โ€” the standard readline / ink-text-input behavior. Docs: home.md + chat-session.md keymaps updated (Backspace/Delete both delete backward). Tests updated. Verified against ink's parse-keypress source; full CLI suite (1283) + lint + typecheck + format + bundle-closure + Leakwatch green; fix adversarially verified (both checks CONFIRMED).
