8ca0455be4* studio/ci: sweep actions/cache@v5 hardening across sibling smoke workflows Follow-up to PR 5396, which fixed the same flake in studio-windows-inference-smoke.yml. actions/cache@v5 has a recurring mode where it logs `Cache hit for: <key>` and then exits non-zero without extracting the archive (see actions/cache#1621 and github community discussion #163260). 12 cache blocks across 8 sibling Studio smoke workflows remained on the vulnerable one-step pattern and would abort before priming HF_HOME / installing Studio on the same flake. Apply the same restore + save split mechanically to every block: - actions/cache/restore@<v5.0.5 sha> with continue-on-error: true - Prime/Download gate widened to also fire on outcome != 'success' so the silent-restore-failure path re-downloads - actions/cache/save@<v5.0.5 sha> with continue-on-error: true, gated on the Prime/Download outcome so we only write a fresh entry when we actually rebuilt the directory Same SHA-pinned action, same cache keys (character-identical), same paths. Existing cache entries keep matching. Only behavior change is that a transient restore-side or save-side failure now falls through to a re-download instead of failing the job. Files touched (12 cache blocks total): studio-api-smoke.yml (1 block) studio-mac-api-smoke.yml (1 block) studio-mac-ui-smoke.yml (1 block) studio-ui-smoke.yml (1 block) studio-windows-api-smoke.yml (1 block) studio-windows-ui-smoke.yml (1 block) studio-inference-smoke.yml (3 blocks: HF, GGUF flat, HF+mmproj) studio-mac-inference-smoke.yml (3 blocks: HF, GGUF flat, HF+mmproj) Verification: all 12 single-step actions/cache@ uses removed, replaced by 12 restore@ + 12 save@; every file parses as valid YAML. * studio/ci: drop continue-on-error from cache/save steps Reverting the save-side continue-on-error addition. Defensive masking of save failures was correct in principle but loses signal: - cache/save@v5.0.5 already swallows ReserveCacheError (the most common save flake) as a non-fatal core.info, so the mask was rarely doing anything today. - A real save-side failure (sustained cache backend outage, blob server 5xx storm) is something we want to see, not hide. Without the signal we would see slow CI for days without knowing the cache layer is broken. - If save flakes start showing up in practice we add this back with concrete evidence. The restore-side continue-on-error stays -- that is the actual fix for actions/cache#1621 silent-restore-failures and removing it would re-introduce the bug.

# Three end-to-end smoke jobs that boot a freshly-installed Studio and
|
|
# exercise the surfaces real users hit through the OpenAI / Anthropic
|
|
# SDKs and curl. Each job picks the smallest model that exercises the
|
|
# behaviour under test, primes HF_HOME via actions/cache, and shares
|
|
# the install.sh --local --no-torch bootstrap.
|
|
#
|
|
# 1. OpenAI, Anthropic API tests
|
|
# gemma-3-270m-it UD-Q4_K_XL (~254 MiB).
|
|
# Password rotation via /api/auth/change-password (old fails,
|
|
# new works), then OpenAI + Anthropic Python SDKs against /v1/*
|
|
# with temperature=0 and a fixed seed. Asserts the four-turn
|
|
# conversation is deterministic across two runs.
|
|
#
|
|
# 2. Tool calling Tests
|
|
# Qwen3.5-2B UD-IQ3_XXS (~890 MiB). OpenAI function calling,
|
|
# server-side tools (python, terminal, web_search) via
|
|
# enable_tools / enabled_tools, and enable_thinking on/off.
|
|
#
|
|
# 3. JSON, images
|
|
# gemma-4-E2B-it UD-IQ3_XXS (~2.4 GiB) + mmproj-F16 (~986 MiB).
|
|
# response_format JSON-schema decoding and OpenAI image_url
|
|
# (data URI) plus Anthropic source/base64 image inputs.
|
|
#
|
|
# All three jobs run in parallel. Total wall time is dominated by job 3
|
|
# on a cold cache; warm cache cuts that to ~3 min.
