v0.4.28 (2026-09-28) — ARIS_REASONING_EFFORT now works on the Anthropic channel (#446): low / medium / high / xhigh / max for the main session and subagents; unset, requests are unchanged. ARIS_MAX_TOKENS raises the output cap when a high effort runs into it. autoCompactEnabled: false in settings turns automatic compaction off. 🐛 #444 tool calls through relays that send a {} placeholder no longer fail with invalid tool input JSON. 🌐 System proxy on Windows / macOS is used without exporting HTTPS_PROXY (#401, by @JasmineLCY); NO_PROXY=* connects directly as before. Upgrading: if you already export ARIS_REASONING_EFFORT, have an OS proxy, or have autoCompactEnabled: false in settings, read the upgrade notes.
v0.4.27 (2026-09-19) — launching and quitting the REPL no longer leaves an empty session file; /resume lists only sessions with messages (#439 follow-up).
v0.4.26 (2026-09-16) — Fable 5.1: the fable alias now resolves to claude-fable-5-1, /model lists Fable 5.1 first (Fable 5 stays selectable) and the system-prompt identity names it; the default executor remains claude-opus-5 (the Mythos tier is $10/$50 vs Opus 5's $5/$25, so the default does not move). Saved executor_model values are ids, not aliases, and are untouched. Pricing already matched on fable; a test pins 5.1. Tests unchanged (aris-cli 225 + 4 e2e / runtime 252 / tools 71 / commands 6). Codex MCP (gpt-6-astra xhigh) gate: GO.
v0.4.25 (2026-09-16) — the reviewer-bridge release. codex-cli 0.154 removed codex mcp-server, the entry point ARIS-Code's aris setup had written into settings.json for every Codex review; on an updated codex every review call died. Built-in codex exec bridge: mcp__codex__codex / codex-reply run as codex exec --json with nothing to register — no settings entry, a legacy codex mcp-server entry is migrated in memory (env, -c defaults, requestTimeoutSecs, trust kept), an explicit Python-bridge entry is used as configured, thread records share ~/.codex/state/codex-exec/threads/ with the Python bridge, 1800 s budget for ultra audits, ARIS_CODEX_BRIDGE=0 restores the old path; aris doctor prints the effective backend. Found on the way: the model never received a Codex result's threadId (it lives only in structuredContent), so codex-reply could not continue a thread — results now start with a threadId: line. /since [full] replays the user's last input and everything after it with the live formatters (display only; after /resume and in --resume batch mode too); a dim hint after turns with ≥ 8 tool calls (ARIS_TURN_SUMMARY=0). #430 Windows consoles deliver no paste event, so each pasted line became its own Enter — lines are now merged into the input and never auto-submitted, Ctrl+C discards the rest (ARIS_PASTE_BURST=0; inferred from crossterm's source, pending confirmation on a Windows machine). #439 /resume lists sessions with [n] indices and ages and accepts an index, a unique id prefix or a path; the last turn is replayed after loading. #428 the .cmd-shim message carries the official native installer one-liner. Bundle 81→83 (pin 3e49e63 → 4734364): /proof-orchestrator, /research-implement-feature, 32 helpers (+review_gate.py, copilot_native_evidence.py, idea_discovery_gate.py), repo-root templates/ bundled; reviewer doctrine and system prompt on gpt-6-astra (fallback gpt-5.6-sol → gpt-5.5), explicit — reviewer: directives win, LlmReview results carry reviewer_model: so HTTP rounds report to review_gate.py truthfully; gpt-6-astra pricing tier $10/$50 (cache write $12.50, read $1). Tests: api 35+6 / aris-cli 225 + 4 e2e / runtime 252 / tools 71 / commands 6, all green; live codex exec fresh + resume roundtrip on codex-cli 0.154.0. Codex MCP (gpt-6-astra): ultra design gate (2 rounds), xhigh implementation gate per step (5/2/2/2 rounds), final whole-diff gate (2 rounds) → GO.
v0.4.24 (2026-08-09) — the Claude 5 model refresh (#392, requested by @YukinoshitaLove). Explicit --model claude-opus-5 / claude-fable-5 already passed through on every platform — this release makes them first-class. Default → claude-opus-5 (main session, subagents, aris setup; same $5/$25 tier as Opus 4.8); the v0.4.18 availability fallback becomes an ordered chain walk (Opus 5 → Opus 4.8 → Opus 4.7, one step per precise 404 not_found_error, explicit choices never silently change) — the naive constant swap would have stranded 4.7-only accounts and configs saved by v0.4.23's setup, a regression the cross-model review caught and an end-to-end mock-404 chain test now locks. /model picker adds Fable 5 / Opus 5 / Sonnet 5; new fable alias. New Mythos-class pricing tier (fable/mythos = $10/$50, cache write $12.50 / read $1, verified 2026-08 — previously fell to the conservative $15/$75 unknown-model tier, a 1.5× over-estimate); Opus 5 / Sonnet 5 pinned on their existing branches. Tests: api 41 / aris-cli 213 + 4 e2e / runtime 226 / tools 70 / commands 5, all green; live smoke on claude-opus-5, claude-fable-5 and the fable alias. Codex MCP (gpt-6-astra xhigh) implementation gate: NO-GO → NO-GO → GO.
v0.4.23 (2026-08-02) — the output-folding release (top real-user complaint: "aris dumps thinking and the full content of documents it reads onto the screen"). 🧹 Tool-output folding, display layer ONLY: the disk-verified culprits were format_read_result appending the ENTIRE read payload, bash pushing full stdout/stderr, grep dumping its full content blob, and the edit preview capping line counts but not line LENGTH. Now Read/Grep show the first 6 lines, Bash shows first 4 + last 4 per stream (stderr keeps its red), each kept line capped at 240 chars (the minified-single-line case), then one dim "… (+N more lines — set ARIS_TOOL_OUTPUT_LINES=0 for full output)" hint. ONE env knob: unset = defaults, a positive integer overrides every tool, 0 = the exact old display; the session, model context, --output-format json and /export are untouched and always complete. Thinking was verified to never print (Anthropic deltas only accumulate; Kimi reasoning_content only feeds the replay cache — the "thinking dump" perception came from the document dumps); two end-to-end sentinel tests (real binary vs mock SSE server) lock that thinking/reasoning never reaches the terminal. Interactive expand/collapse was deliberately rejected as over-engineering. 🐛 Bash timeout now kills the command: a timed-out call reported interrupted: true while the dropped tokio future left the child RUNNING — side effects landed after the report; now kill_on_drop (escape hatch ARIS_BASH_KILL_ON_TIMEOUT=0; background tasks untouched; locked by a real behavioral test — a timed-out "sleep 1 && touch marker" must not create the marker). 📦 Bundle 79→81 (pin 7182624 → 3e49e63): /integrity-forensics — the Anti-Autoresearch SHA-pinned thin launcher (span-anchored evidence ledger → GPT auditors propose → deterministic rules-only adjudicator decides → typed BLOCK/WARN gate + obligations ledger) — and /web-debug-search, +tools/forensics_gate.py (29 helpers, 104 embedded resources). 🎁 Also: grep's content mode no longer shows a false "0 matches" above real results (the gate caught that "numMatches": null serializes with the key present, defeating a naive presence check); all four crates' local-mock-server tests are now proxy-immune (a shell with http(s)_proxy set used to turn 15 tests red on a released tag — 127.0.0.1 was routed through the proxy). The rest of the runtime-state package (compaction re-arm, failed-turn cleanup, /cost dollars, SSE tail) ships as v0.4.24 — the cached-token cost fix is deliberately held back because it changes what the compaction trigger measures. Tests: api 41 / aris-cli 212 + 3 e2e / runtime 225 / tools 69 / commands 5 (+13), all green under a live proxy; new-code clippy delta zero. Codex MCP (gpt-6-astra): ultra scope+design adjudication, then a 3-round implementation gate (round 1 caught the null-serialization defeat and a non-hermetic behavioral test; round 3 GO).
v0.4.22 (2026-07-12) — the skills-resync + GPT-6-Astra release. 📦 Bundle resync (pin 7e3ab67 → 7182624, 93 commits): 79 bundled skills (+meta-apply, +paper-poster-html; paper-poster retired to a redirect stub), 28 tools helpers (8 new: capture_filter, evidence_check, iteration_log, provenance, run_state, threat_scan, meta_opt/trigger_eval + sample evals), 11 new shared-references docs (fan-out-pattern, acceptance-gate, external-cadence, skill-governance, compute-env-contract, resumable-runs, evidence-precheck, injection-hygiene, capture-antipatterns, output-composition, taste-calibration); sync hardening — ARIS_SYNC_EXPECT_SHA guard (aborts before touching assets if main moved; it caught a real move on first use) + exact-inventory drift tests + the vendored posterly MIT license text now ships. 🎛 GPT-6-Astra two-tier reviewer alignment: the CLI's system-prompt nudge now passes the skills' explicit model: gpt-6-astra + per-call effort pins through (the v0.4.17 blanket "never pass a model" rule would have silently stripped deep audits from ultra to xhigh), carries the canonical capability-only fallback chain (effort-unsupported → same model xhigh, deep tier only; model-unknown → explicit gpt-5.5+xhigh; never degrade on transport-class errors; an explicit call-level override disables the chain), pins approval-policy: "never" + explicit sandbox on every fresh codex call, and makes the HTTP fallback pre-dispatch-only with parameter stripping; the HTTP LlmReview default deliberately stays gpt-5.5 pending a real smoke; gpt-5.6 family pricing (sol $5/$30, terra $2.50/$15, luna $1/$6) verified against the official page; banner/Reviewer display//reviewer are honest about primary-vs-fallback (pure-Codex setups get status + guidance instead of a fake picker). 🐛 8 verified fixes: explicit --model was silently overridden by the saved executor model (model provenance now tracked end-to-end; the 4.8→4.7 availability fallback respects explicit choices; /model and /setup re-arm it); saved models no longer leak across provider transports (blank saved models count as absent; OpenAI transport with no model source fails fast; the first-run wizard's config now actually feeds startup model resolution); --output-format json never prompts (locked by a real end-to-end binary test against a mock SSE server); Windows aris login fixed (PKCE randomness read /dev/urandom → getrandom); Windows command probing fixed (the PowerShell tool probed itself through sh; now where.exe); codex .cmd shims classified honestly (three-state probe; setup requires explicit confirmation before writing a config the MCP client can't spawn); nested config.json warns instead of silently parsing to all-defaults; NotebookEdit mints collision-free cell ids. (workspace compile gate + three targeted test groups, each guarded against silent 0-test green). Tests: api 41 / aris-cli 204 + 1 e2e / runtime 223 / tools 69 / commands 5 (+54), all green; new-code clippy delta zero. Codex MCP (gpt-6-astra): design gate — 5 rounds, NO-GO ×4 → GO — then a 3-round implementation gate whose round 2 caught a first-run config-wiring blocker before it shipped; 4 implementation subagents, every report disk-verified.
v0.4.21 (2026-06-28) — bug-fix patch: 5 new user-facing bugs from a Codex adversarial hunt (all disk-verified, distinct from v0.4.20), each cross-model reviewed at a design gate and an implementation gate (gpt-5.5 xhigh; both started NO-GO — the reviewer caught an off-by-one in the grep line-mapping and a missing stream-level test before GO). 🐛 Headline: OpenAI-compatible streaming corrupted multi-byte UTF-8 (CJK / emoji) split across network chunks into � — each HTTP body chunk was from_utf8_lossy'd independently, so a 3-byte Chinese character or 4-byte emoji straddling a chunk boundary broke on both sides (a frequent hit for Chinese users on domestic OpenAI-compatible providers — Kimi/GLM/MiniMax/DeepSeek/Qwen/Doubao — streaming Chinese text); the stream buffer is now raw bytes, decoding only complete SSE lines. A saved OpenAI/custom executor config no longer overrides a shell-set EXECUTOR_PROVIDER — the startup "shell-provided vars win" path had one ungated write that re-pointed EXECUTOR_PROVIDER=anthropic … aris … to OpenAI (wrong executor / model-not-found). An Anthropic stream truncated after content but before a terminal signal now hard-errors (premature_eof) instead of saving a half-finished answer to history as a complete turn (symmetric to the OpenAI #249 guard; the stop_reason-only compat path is preserved, and ARIS_ALLOW_EOF_WITHOUT_STOP=1 opts a terminal-signal-less proxy back into the old behavior). grep_search with multiline: true now matches across lines in content mode (was silently empty — count mode already worked). MCP tool results carried only in structuredContent (empty content) are no longer dropped — the model gets the JSON structured payload. Tests (CI mode): api 32→35 / runtime 205→212 / tools 67 / aris-cli 172→181 / commands 5 (+21, incl. 2 stream-level integration tests), all green. Codex MCP (gpt-5.5 xhigh): design gate (NO-GO → GO after fixing the off-by-one) → implementation gate (NO-GO → GO after adding the stream-level integration tests); the Anthropic streaming spec (every stream ends with message_stop) was WebFetch-verified. Two latent-only candidates (Anthropic block-index routing, OpenAI multi-line SSE) remain deferred.
v0.4.20 (2026-06-19) — bug-fix patch: 7 user-facing bugs surfaced by a Codex adversarial hunt, each reviewed across 3 rounds (the reviewer caught a redraw gap, a trailing-blank, a spinner tail, and a blank-line edge before GO). 🐛 Headline (#299): short REPL replies showed only "✔ Done" — the spinner draws "⠋ Thinking…" with Save/RestorePosition so streamed output overwrites it on the same line, but finish then cleared that whole line, erasing a short single-line reply. The REPL now finishes without clearing when the turn printed visible text (Clear(UntilNewLine) wipes only the spinner tail after the reply). Streamed multi-paragraph replies rendered glued ("para1para2") — each chunk's paragraph separator was trimmed at the stream boundary; the markdown streamer now preserves separators via a held-separator so streamed output equals a single full render (no dangling blank line). Markdown tables with CJK/fullwidth content misaligned — width now counts display cells (CJK = 2), not chars. aris "prompt" / --print ignored the executor model saved by aris setup (REPL-only before) — a configured OpenAI/custom executor got the Anthropic default sent to its endpoint; the one-shot and REPL paths now share one resolver. Esc now actually closes the completion dropdown (it was recomputed right back). glob_search reports the total matched count when truncated (not the capped 100, which made the model think a 1000-match glob had 100 files). /model's custom menu reads the effective env the executor uses, not stale on-disk config. Tests (CI mode): api 32 / runtime 205 / tools 67 / aris-cli 172 / commands 5, all green; +7 new; real-machine verified (short reply renders + "✔ Done"; paragraphs keep their blank lines). Codex MCP (gpt-5.5 xhigh): hunt → 3 review rounds (NO-GO → NO-GO → GO). Two latent-only candidates (Anthropic block-index routing, OpenAI multi-line SSE) deferred to a hardening pass.
v0.4.19 (2026-06-14) — honesty / guardrails patch (theme from a Codex fresh-eyes audit; no behavior change for healthy setups). 🔴 MCP protocol-version negotiation guard — the stdio handshake requested 2025-03-26 but never read the version the server negotiated back (a parsed-but-dead field), so a server agreeing on a version ARIS can't speak was silently accepted and later tools/list / tools/call ran on an incompatible protocol with opaque failures. ARIS now validates the negotiated version against a supported set (2025-11-25 / 2025-06-18 / 2025-03-26 / 2024-11-05 — stdio framing is identical across these) and, on an unsupported one, terminates the child + clears the slot + surfaces a clear per-server error (aris doctor shows it) — the "terminate when versions can't be agreed" behavior the MCP lifecycle spec requires. The request stays 2025-03-26 (proven against codex mcp-server), so healthy servers are unaffected — verified end-to-end: the real Codex MCP server still spawns + initializes + advertises its tools under the guard. 🧹 Papercuts: the OpenAI-family subagent fail-loud message dropped its stale "lands in v0.4.18" marker (now version-agnostic + actionable, still credential-free); OpenAI upstream error bodies are now truncated (500 chars) + credential-redacted (sk-… keys and Bearer … tokens, via a substring scanner that catches the compact-JSON shape {"api_key":"sk-…"} a misconfigured proxy can reflect back) instead of splatted verbatim; the system-prompt hook-events summary now counts only the hooks the runtime actually executes (a command hook with a command string), matching the parser. Tests (CI mode): api 32 / runtime 204 / tools 67 / aris-cli 167 / commands 5, all green; live smoke confirms the real Codex MCP server still initializes under the guard. Reviewed by Codex MCP (gpt-5.5 xhigh): design GO → impl NO-GO (compact-secret miss + command-string strictness) → GO after fixes.
v0.4.18 (2026-06-14) — default model → Claude Opus 4.8, with corrected pricing and a safety net. The bump moves DEFAULT_MODEL, the opus alias, the model picker, aris setup, and the subagent default to claude-opus-4-8 — with an availability fallback: if the account lacks 4.8 (the API returns 404 not_found_error), ARIS auto-falls-back to claude-opus-4-7 for the session, rebuilds the system-prompt model identity so it stays coherent (the model is never told it's 4.8 while served 4.7), warns once, and retries — for the main session (text + JSON) and subagents. It fires only on that precise 404 (never 400/rate-limit/auth), latches against loops, and the text path rebuilds from a pre-turn snapshot so a retry never double-appends the user message; accounts with 4.8 are byte-identical to a plain bump. 💰 Pricing corrected (verified against Anthropic's published schedule; had been a 3–5× over-estimate): current Opus 4.5–4.8 = $5/$25 (deprecated Opus 4/4.1 keep $15/$75, split by word-boundary so a future opus-4-10 isn't mis-tiered); Sonnet 4.x = $3/$15 (decoupled from the generic unknown-model fallback, which stays $15/$75); Haiku was already correct. 🧹 Backlog: aris setup option 10 pins the Codex MCP reviewer to model_reasoning_effort="xhigh" (deterministic for new setups, independent of ~/.codex/config.toml; idempotent merge never clobbers an existing entry); a startup + aris doctor misconfig hint (#259) for a silently-ignored/misplaced config (malformed JSON, or a stray ~/.aris/config.yaml — stderr-only so --print/JSON stdout stays clean); the system-prompt hook summary now marks parsed-but-never-fired events "PARSED ONLY … will NOT run" instead of implying dead hooks run (full event expansion — actually firing SessionStart/SessionEnd/… — deferred to a separate issue). Tests (CI mode): api 32 / runtime 202 / tools 67 / aris-cli 166 / commands 5, all green; a live one-shot smoke returns model=claude-opus-4-8 end-to-end. Reviewed by Codex MCP (gpt-5.5 xhigh) across the design + both implementation batches (design REWORK→GO, impl NO-GO→GO, batch-2 GO).
v0.4.17 (2026-06-13) — the MCP release. Before v0.4.17, mcpServers in settings.json parsed, showed in aris doctor, and did nothing; now ARIS spawns each configured stdio server, runs the MCP handshake, discovers tools, and advertises them as mcp____ on both provider paths (Anthropic + OpenAI-family), with end-to-end dispatch, soft per-server degradation, and an approval gate for untrusted MCP tools (external processes the sandbox can't cover; --allowedTools now accepts mcp__ names). 🆕 zero-API-key cross-model reviewer: aris setup → option 10 (Codex MCP, ChatGPT subscription, no API key) writes an idempotent mcpServers.codex entry into the settings file the runtime actually reads (atomic write + backup, explicit consent before trust: true), with an optional API reviewer as fallback (ARIS_REVIEWER_PROVIDER=codex-mcp + ARIS_REVIEWER_FALLBACK_PROVIDER); /setup in-REPL rebuilds the system prompt + runtime so reviewer changes take effect without quitting. 🔴 Protocol fix the fakes couldn't catch: real-machine e2e against codex mcp-server exposed that our stdio transport spoke LSP-style Content-Length: framing while the MCP spec (and codex) use newline-delimited JSON-RPC — every fake-server test passed because the fakes spoke the same wrong dialect; writes are now NDJSON, reads auto-detect both, and the spec-mandated notifications/initialized is sent after initialize (a select-based round-trip also closes the #286 large-request deadlock). Hooks: object-style Claude Code hooks preserve matcher / timeout / async (anchored-regex matcher filtering; per-hook timeout, default 30 s kill = warning not deny). Long tail: ARIS_DISABLE_KEYCHAIN gate, Anthropic stop_reason clean-EOF symmetry (CL2), OpenAI tool-call index-missing merge-by-id (OE6), slash commands enter history. Real-machine push-gate hardening (the zero-key reviewer's first run): codex codex/event notification spam silenced by default (gated behind ARIS_MCP_STDERR=inherit), the system prompt now tells the model not to pass a model parameter to Codex (account default = gpt-5.5 + xhigh; arbitrary names are rejected by a ChatGPT account), and a Codex-MCP-primary-with-no-fallback call returns a clear "use " message instead of a misleading / error. Built with the v0.4.16 zero-regression methodology (24 new characterization tests; every deliberate flip annotated in-place). Tests (CI mode): runtime 199 / aris-cli 165 / tools 67 / api 30 / commands 5, all green. Reviewed phase-by-phase by Codex MCP (gpt-5.5 xhigh) across 17 rounds (7 NO-GOs all resolved). Subagent MCP routing (P8) + MCP bump + hook execution deferred to v0.4.18.
v0.4.16 (2026-05-30) — REPL UX + provider hardening, shipped under a zero-regression discipline: 64 characterization ("golden") tests locked the current provider-routing / pricing / reviewer / subagent / REPL behavior first, then stayed green through every change. Closes #274: command history now persists to ~/.config/aris/history (0600) and reloads on startup, with an ARIS_NO_HISTORY kill-switch and a disk-only secret-skip (credential-looking lines stay in in-session history but never touch disk); bash-style Ctrl+R reverse incremental search (CJK display-width-aware single-line render; no existing key binding changed; no new dependency). Security: an OpenAI-family main session (Kimi / GLM / MiniMax / …) spawning a subagent previously silently billed the user's Anthropic OAuth/Keychain credential — it now fails loud with a clear, credential-free error; full OpenAI-family subagent routing is a cross-crate change deferred to v0.4.17. Groundwork (no behavior change): the 3 byte-identical word-boundary matchers consolidate into one canonical runtime::word_match; new pure ProviderFamily classifier (unwired). Tests (CI mode): runtime 164 / aris-cli 128 / tools 49 / commands 5, all green. Codex MCP (gpt-5.5 xhigh) reviewed each phase + a final integration pass.
v0.4.15 (2026-05-29) — OpenAI-compatible streaming robustness hotfix. Closes #249: MiniMax (and other OpenAI-compatible providers / proxies) were effectively unusable because the clean-EOF completion check treated the data: [DONE] SSE sentinel as the only authoritative signal. A non-empty choices[].finish_reason is the Chat Completions spec's terminal-chunk marker; [DONE] is a transport convention some compatible providers never emit (MiniMax sends finish_reason: "stop" then closes without [DONE]). The clean-EOF decision is now a pure, unit-tested stream_eof_action(...) that completes on EITHER [DONE] OR a non-empty finish_reason; reads are NOT stopped early at finish_reason (a trailing include_usage usage-only chunk is still consumed), genuine truncation still hard-errors, and a pre-output proxy abort still restarts. Coupled fixes: OE7 reads finish_reason before the delta guard (delta-less terminal choice); OE2 flushes pending tool calls on any non-empty finish_reason; OE4 surfaces a mid-stream error envelope as a hard error instead of silently dropping it; OE3 tolerates data:{...} without the space after the colon. +5 unit tests (77→82) extract the previously-untested SSE completion logic into pure helpers. Anthropic SSE path untouched. Codex MCP (gpt-5.5 xhigh) 3 rounds (GO-WITH-NITS → GO-WITH-NITS → GO).
v0.4.14 (2026-05-25) — Security-hygiene release closing the top items from the v0.4.13 codex audit (gpt-5.5 xhigh, 6/10 NEEDS-REWORK verdict). 🔴 S9 (P0) system-prompt config redaction — before v0.4.14, render_config_section() dumped the merged settings.json verbatim into the system prompt sent to the LLM provider, leaking env, mcpServers..headers.Authorization Bearer tokens, hook command env, signed-URL query params, and apiKey fields. New renderer whitelists top-level fields (model/permissionMode/theme/outputStyle/permissions/sandbox with recursive redaction inside), redacts sensitive keys (apikey/token/secret/password/authorization/headers/env/_KEY/_SECRET/_TOKEN), replaces MCP command with placeholder, reduces MCP `url` to strict origin (scheme allow-list http/https/ws/wss, ASCII host, digit-only port, IPv6 brackets), and drops hook command strings entirely. Regression test exercises 9 distinct leak surfaces; URL parser has its own targeted test for 7 smuggling attempts including port-position secret injection (codex round-3 catch). 🟡 P9 (P1): DeepSeek aris --help now points at aris setup option 7 instead of an env-var path the resolver never honored. 🟡 M1/M2 (P1) doc: aris doctor + README/README_CN gain experimental warning whenever mcpServers.len() > 0 (full MCP tool dispatch lands v0.4.16). 🟢 C11 (P2) stream idle timeout — both Anthropic MessageStream and the OpenAI SSE loop wrap response.chunk().await in tokio::time::timeout (env ARIS_STREAM_IDLE_TIMEOUT_SECS, default 120, clamp [10, 1800], 0/negative disables); closes the "aris hangs forever with no output" symptom when an upstream HTTPS proxy holds a connection without keepalives. Bundle: 77 skills (+1 /wiki-enrich via late same-day sync to main 7e3ab67 which also picks up upstream check_ready.sh awk + grep-c null-match fix), 54 helpers. Codex MCP 6 rounds (NO-GO + 4 → GO-WITH-NITS + 3 → NO-GO + port smuggling → GO → release metadata GO → sync GO).
v0.4.13 (2026-05-25) — Residue-cleanup release closing every codex audit P1 carried since v0.4.10–v0.4.12, plus the long-tail regression tests. 🟡 v0.4.10 P1.D per-server MCP timeout — mcpServers..requestTimeoutSecs override > MCP_REQUEST_TIMEOUT_SECS env > 300s default (clamped 1..=1800), so one Codex MCP agent can run 5 min while filesystem MCP errors in 5 s. 🟡 v0.4.10 known limitation closed — McpStdioProcess::request() skips JSON-RPC notifications (id absent/null) and keeps reading until the correlated response. 🟢 meta_opt hook deploy via aris init — tools/meta_opt/{log_event,check_ready}.sh bundle into the binary; aris init writes ARIS-namespaced aris-meta-opt-log-event.sh / aris-meta-opt-check-ready.sh to ~/.claude/hooks/ (codex round-1 #1: never clobbers user hooks); settings.json merge idempotent, backups hard-fail, final rewrite atomic via tempfile + rename. 🧪 9 v0.4.12 targeted regression tests for sandbox.strictMode (3) + parse strictMode + provider_match pricing + has_word o-series + stream_options 400 + meaningful-content classification + premature-EOF retry truth table (codex round-1 #3 — should_retry_on_premature_eof() extracted to pure fn, 7-row test). Bundle: 76 skills, 54 helpers (+2 meta_opt scripts vs v0.4.12). Codex 3 rounds (NO-GO + 3 → NO-GO + metadata → GO).
v0.4.12 (2026-05-22) — Bug-fix + small-feature release. #238 sandbox.strictMode opt-in config key; when set, SandboxConfig::resolve_request() ignores all five LLM-supplied overrides (dangerouslyDisableSandbox, namespaceRestrictions, isolateNetwork, filesystemMode, allowedMounts) — closes the gap where a tool call could silently bypass user sandbox policy. aris doctor adds a "Sandbox:" row; bash tool schema documents the strictMode semantics. #232 auto-review-loop-llm updated from legacy deepseek-chat / deepseek-reasoner (deprecate 2026-07-24; reasoner rejects tool_choice) to deepseek-v4-flash / deepseek-v4-pro. v0.4.10 audit P1 follow-ups: P1.A Anthropic stream retry gates on has_emitted_meaningful_content (a stream that only sent MessageStart before EOF is retry-eligible); P1.B supports_reasoning_effort + reviewer mirror use word-boundary match so openai/o3-mini / proxy:o4 route correctly; P1.C stream_options.include_usage:true proxy fallback retries once without on real 400 unknown-field errors; P2 pricing match precision via provider_match() so qwen3.6-plus / kimi-k2.5 route correctly while my-kimi-clone does not. Skills sync (76 skills, 52 helpers): /interview-cheatsheet + /render-html newly bundled; build.rs ALLOWED_EXTS gains html for render-html templates; EXCLUDED_SKILL_PREFIXES → starts_with("skills-codex"). CI fetch-depth: 0 + origin/main fetch so drift-test ancestor check runs. Cross-reviewed by Codex MCP (gpt-5.5 xhigh) over 4 rounds.
v0.4.11 (2026-05-18) — Skills bundle refresh + sync infrastructure. The embedded skills set in the v0.4.10 binary had fallen behind main (~6 of 56 main skills/ commits had been cherry-picked); v0.4.11 syncs the full set and ships sync infrastructure so the gap can't silently reopen. Bundle: 65→74 user-facing skills, 34→49 helper resources. 10 new skills bundled: /citation-audit (fourth-layer bibliography audit), /experiment-queue (SSH multi-seed job queue with OOM retry), /kill-argument (two-thread adversarial review for theory papers), /resubmit-pipeline (W5: text-only port to a new venue), /paper-talk (end-to-end conference talk pipeline), /slides-polish (per-page Codex layout review), /overleaf-sync (two-way Overleaf Git-bridge), /gemini-search + /openalex (broader literature sources), /qzcli (Qizhi GPU jobs). 46 existing SKILL.md refreshed — most critically the canonical resolver chain rollout (closes real user incident where /research-wiki was empty for a week from hardcoded tools/research_wiki.py), submission assurance gate + external verifier (/paper-writing Phase 6 now functions). tools/ goes 9→18: 9 baseline helpers refreshed (research_wiki.py 315→767 lines with canonical ingest_paper API), 9 new helpers (extract_paper_style.py, figure_renderer.py, paper_illustration_image2.py, overleaf_{setup,audit}.sh, verify_wiki_coverage.sh, watchdog.py, experiment_queue/{build_manifest,queue_manager}.py). New tools/sync_main_skills.sh automates main → bundle rsync with symlink pre-flight + codex-mirror prune + SKILLS_SOURCE_COMMIT pinning. 3 new CI drift tests in crates/runtime/src/cache.rs cover all 4 resolver layer patterns. Gemini MCP calls in /research-lit and /gemini-search now pass model: 'auto-gemini-3' (avoids silent downgrade to 2.5-pro on OAuth-personal capacity exhaustion). CLI runtime unchanged — codex-audit P1 follow-ups remain on v0.4.12 backlog. Cross-reviewed by Codex MCP (gpt-5.5 xhigh) across 5 rounds (REQUEST CHANGES → APPROVE WITH NITS → NO-GO → GO → final GO).
v0.4.10 (2026-05-17) — Stream + MCP reliability + multi-provider pricing. C6 whole-stream restart in Anthropic MessageStream + OpenAI SSE loop on chunk decode failure / premature EOF (ARIS_STREAM_RETRY, default 2, clamp 0..=5, fires only when nothing emitted yet — closes #228-style "error decoding response body" loop). M3 MCP stdio gains 300s default tokio::time::timeout over send+read (override MCP_REQUEST_TIMEOUT_SECS, clamp 1..=1800); response.id ↔ request.id correlation; ensure_server_ready() try_wait() dead-process respawn; kill().await on all failure paths so the next call starts clean (closes #151 / #172 "Calling codex..." stalls). C8/P4 OpenAI streaming requests now send stream_options.include_usage:true + parse cached_tokens; Anthropic streaming merges MessageStart.usage (input/cache) with MessageDelta.usage (output). C9 multi-provider pricing registry (15+ models, OpenAI cache_read = input × 0.1 corrects 5× generic overstatement, DeepSeek cache_hit/cache_miss tiers, has_word() boundary matcher for provider/ slugs). 9 dead-code warnings cleared; aris setup help text synced with actual behaviour.
v0.4.9 (2026-05-17) — Closes Codex v0.4.7 audit residuals (L1 TLS double-stack, L3 reasoning_cache compaction misalign, L4 reasoning replay unbounded). 2 new skills bundled (/figure-spec + /paper-illustration-image2 with scripts/ subdirs, new Layer 0b = $ARIS_CACHE_DIR/skills//scripts/); research_wiki.py promoted to shared tools/ (9+ callers); 5 more SKILL.md migrated to fallback chain.
v0.4.8 (2026-05-17) — Skill helper subsystem rewrite. Bundled helpers extract to ~/.config/aris/cache// at startup; every Skill invocation surfaces helperReport JSON + 4-layer resolver preamble; /skills export copies helpers; new integration-contract.md with 6 failure policies; 8 shared helpers (arxiv/deepxiv/exa/S2/openalex/save_trace/verify_papers/verify_paper_audits) bundled; /research-lit + /deepxiv migrated. Plus 4 bug fixes: gpt-5.5+tools 400 on OpenAI; Custom reviewer reset; missing signature field (#228); --version Build date hardcoded.
v0.4.7 (2026-05-16) — DashScope Coding Plan 405 fixed (#159) via native-tls switch (#225); reasoning_content replay for all reasoning models (OpenAI o1/o3/o4 / DeepSeek-R1 etc.), not just Kimi (#226); 600+ lines dead code cleanup + rustyline dep removed + "Claw Code" → "ARIS-Code" rebrand.
v0.4.6 (2026-05-14) — 🚨 Two long-standing silent bugs fixed: PermissionMode::Prompt silently allowed every tool (derived-Ord bug); system prompt hardcoded current_date = "2026-03-31" made models reject post-cutoff data as future/prompt-injection. Plus Custom OpenAI-compatible provider (/setup option 11) with dynamic /models discovery (@Anduin9527 #221 + #222).
v0.4.5 (2026-05-13) — First-class reasoning-model support: thinking content blocks end-to-end (fixes #161) + reasoning_effort='xhigh' for GPT-5.5 / o1 / o3 / o4 / DeepSeek-thinking. DeepSeek V4 Pro + Xiaomi MiMo + Qwen 3.6 + Doubao in /setup (options 7-10). Object-style hooks parser. Default model bumped to Claude Opus 4.7 + GPT-5.5. REPL input hardening (multi-line wrap / Cmd+V paste / CJK boundary). GitHub Actions CI. Credits: @GO-player-hhy (#186), @Jxy-yxJ (#171), @GetIT-Sunday (#216 partial).
