From 01aa7f3e8fdd3a9b17c4107d94bb6f7b834e2e2c Mon Sep 17 00:00:00 2001 From: Your Name Date: Mon, 7 Sep 2026 07:25:38 -0400 Subject: [PATCH] =?UTF-8?q?fix:=20OpenRouter=20402=20=E2=80=94=20send=20ma?= =?UTF-8?q?x=5Ftokens=20cost=20cap;=20make=20session=20window=20configurab?= =?UTF-8?q?le?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit User hit 'API error 402: ...

Architect decisions: - AI_MAX_TOKENS (num, default 2048): sent as max_tokens on OpenRouter and generationConfig.maxOutputTokens on Gemini — a real per-request cost ceiling. llamacpp unchanged (local/free, no pre-check). - AI_SESSION_TURNS (num, default 40 kept back-compat; messages, 2 per exchange — 10 = last 5 conversations): resolved lazily in session_push because config loads after the hardcoded line-25 default. - Both registered in the bin/pos-ai POS_CONFIG @General section, so they appear in 'pos config ai' with num: validation.

User hit OpenRouter 402 on the `assist` alias: "You requested up to 131072 tokens, but can only afford 4511" — no provider sent `max_tokens`, so OpenRouter pre-bills the routed model's full worst-case output (131072 on `openrouter/auto`); user also asked to bound session history to last-5 requests. Architect decisions: `AI_MAX_TOKENS` (num, default **2048**, real cost cap) sent as `max_tokens` on OpenRouter and `generationConfig.maxOutputTokens` on Gemini (llamacpp skipped — local/free); `AI_SESSION_TURNS` (messages, 2 per exchange; default 40 kept back-compat; 10 = last 5 conversations) resolved lazily in `session_push` because config loads after the hardcoded line-25 default; both registered in the `bin/pos-ai` `# POS_CONFIG:` `@General` section → visible in `pos config ai`.

Tester regression round not run this cycle (user's call); permanent coverage remains a follow-up. + - **2026-09-06** — `pos ai alias` create-flow silent abort + bogus step labels. User hit: pressing Enter on "System prompt (empty = use built-in)" silently returned to the menu (no alias created); step counters showed `[1/4] [2/4]` in a 5-step flow. Detective: `menu_ask_value` (lib/menu-lib.sh) contract returns rc 1 for empty+no-default, collapsing "empty" with "cancel"; the Step 4 call at `:410` passed `""` default so the advertised empty answer triggered `|| return 0` → silent abort; same latent trap at alias-name `:353` (re-prompt dead code). Pre-existing (introduced with the alias feature `f61766b0`/`9f289ba3`/`300b742a`), NOT a 2026-09-06 regression; 11 other `menu_ask_value` callers correct (6 external rely on empty=cancel, 4 pass defaults) → no global semantic change allowed. Architect: opt-in `--allow-empty` flag on `menu_ask_value` (backward-compatible; empty+no-default → rc 0 empty value, genuine cancel/EOF → rc 1, default wins) + step labels fixed to `/5`.

User chose to commit without the Tester regression round (report: `AgentsReport/tester/2026-09-06_alias-menu-tests.md` — pty feasibility proven, steps 2-6 pending). - **2026-09-06** — AI server breakage post-llamacpp install — four root causes found and fixed (Detective→Architect→Builder→Tester chain).

Architect DQ1-DQ6: help-gated validation stays; dir-expansion never silently picks; `ensure_user_bus` in `lib/common.sh` pre-flights all three tools; `--no-unit` direct-run escape hatch for SSH/headless; candidates narrowed to `llama-server`/`llama-server-cuda`; port pinned 8088; installer post-install sanity.

Pathological but config-ui-enterable. Covered by the same fix as Findings 1/2. + +## Step 4: Config surface — [PASS: static] / [UNVERIFIED: runtime] + +- Registry (`lib/registry.sh`) is format-driven: `reg_config_keys <scope>` echoes the whole `# POS_CONFIG:` line(s) per scope; the `ai` scope line (pos-ai:6) now contains `AI_MAX_TOKENS=num:…` and `AI_SESSION_TURNS=num:…` inside `@General`, exactly matching the proven `LLAMACPP_CTX_SIZE=num:…` pattern. config-ui renders `@`-captioned sections. +- Static conclusion: both keys ARE discoverable under scope `ai` in `@General`. Runtime `reg_config_keys ai` / `pos config ai` display could not be executed (sandbox denies `source`/bash) → **UNVERIFIED**; Orchestrator/next agent can re-run. +- Note: `bin/pos-ai-hf` also declares scope `ai` (pre-existing); both lines merge under `ai` — unchanged behavior. + +## Step 5: Doc sync — [PASS] + +- `DOC/POS.md:94-95` new rows: `AI_MAX_TOKENS` no/`2048`/"Max output tokens per request (OpenRouter/Gemini cost cap)"; `AI_SESSION_TURNS` no/`40`/"Session message cap — 2 per exchange; 10 = last 5 exchanges" — consistent with header + code (2048 default; 40 messages = 20 exchanges; 10 = 5 exchanges). `:64` parenthetical true (default unchanged). +- `DOC/HOWTO.md:45` and `DOC/AGENT_Context_Project.md:491` append both vars. ✓ +- GEN blocks: only the filetable row `bin/pos-ai 705→709` changed (inside `GEN:START filetable`/`GEN:END`, AGENT_Context 614-662); `wc -l bin/pos-ai` = 709 → the generated row is byte-consistent with the file, so a `make gen` rerun would be a no-op for that row. Other GEN blocks and `completions/pos.bash` untouched (no key-level completion table exists — config is read live from headers). Hand-maintained Key-File rows (AGENT_Context:593-613) do not include `lib/ai-providers/*`, so "no bump needed" is correct. + +## Step 6: Gates — [UNVERIFIED] + +Sandbox permission rules deny `make`, `bash`, `source`, `jq`, `mkdir` (allowlist: git read commands, head/tail/wc/sort/grep/rg only).

Post-fix the request body carries `max_tokens: 2048`, so the pre-check estimate ≈ input_tokens + 2048 (output) instead of + 131072. With the terse `ask` prompt (~200 input tokens) the estimate is far under the ~4511-token affordance → 402 resolved for typical requests. Math is plausible. +- Caveats for the user (also in Findings → caveats below): (1) if the auto-routed model's *output* price per token is steep, 2048 output tokens can still exceed the balance → 402 persists; set an explicit cheaper `OPENROUTER_MODEL` or switch `AI_PROVIDER=gemini`/`llamacpp`. (2) `max_tokens:2048` truncates long `--full` answers (raise the var). (3) Live OpenRouter/Gemini repro was not run (no network, no key) → UNVERIFIED. + +--- + +## Findings + +**Finding 1 — REQUIRED** +- **Evidence:** `lib/ai-providers/openrouter.sh:22-23` and `lib/ai-providers/gemini.sh:17-19` pass `${AI_MAX_TOKENS:-2048}` straight into jq `($mt|tonumber)` with no range/format guard. `lib/config-ui.sh:419` `num:` validation accepts `^-?[0-9]+$` — so `AI_MAX_TOKENS=0`, `-5`, `010` are all savable via `pos config ai`. Consequences: `0`/`-5` → provider 400 on every request (OpenRouter `max_tokens` must be ≥ 1; Gemini `maxOutputTokens` ≥ 1); `010` → jq invalid numeric literal → command substitution fails → `set -euo pipefail` (pos-ai:2) aborts the whole CLI with a raw jq error; same raw abort for a non-numeric value hand-set/exported (e.g. `AI_MAX_TOKENS=abc`). The sibling `AI_SESSION_TURNS` got an explicit guard (pos-ai:290-291) — the asymmetry shows the guard pattern was intended but not applied to the token cap, and the session guard itself misses leading-zero values (see Finding 2). +- **Relevant files/lines:** openrouter.sh:22-23; gemini.sh:17-19; config-ui.sh:419; bin/pos-ai:290-291. +- **Approved scope reference:** design §Decision 1 (providers read `${AI_MAX_TOKENS:-2048}`), §Decision 5 ("empty/unset values fall back to documented defaults" — satisfied, but 0/negative/leading-zero are neither empty nor unset). +- **Why it matters:** a value the project's own config UI accepts (0 — a plausible "no cap" attempt, valid on some OpenAI-compatible backends) hard-breaks both remote providers until manually cleared; the new var is the 402 fix, so its input path should fail closed to the safe default, matching the guarded sibling var. +- **Fix demand (Builder, in scope):** in both providers, before jq: `mt="${AI_MAX_TOKENS:-2048}"; [[ "$mt" =~ ^[1-9][0-9]*$ ]] || mt=2048` (also rejects 0, negatives, leading zeros, empty, non-numeric) then `--arg mt "$mt"`. 2-3 lines each. + +**Finding 2 — NOTE (folded into Finding 1's fix)** +- **Evidence:** `bin/pos-ai:290-291` guard is `^[0-9]+$` + `(( n >= 1 ))`; `AI_SESSION_TURNS=010` passes both (octal 8) then `--argjson n "010"` is an invalid JSON numeric literal → jq abort. Pathological, but config-ui-enterable. Fix: switch the session guard to the same `^[1-9][0-9]*$` pattern. + +**Finding 3 — NOTE (unverified runtime claims)** +- Gates/suite/live-402 claims from the Builder report could not be re-run under the sandbox (deny rules). The Orchestrator must run `make gen`/`make check`/`make lint`/`make test` and, if desired, a live OpenRouter repro before merge.
