Create Artifact Container failed: The artifact name activation is not valid.\n```\nThis happens **before** the `agent` job starts (0 tokens spent), so it's a pure infra/naming failure, not an agent or content issue.\n\n### Affected workflows and run IDs\n\nConfirmed (all failed at 2026-08-19 ~23:48 UTC, same step, same job):\n- Smoke OTEL — [§32314809023](https://github.com/github/gh-aw/actions/runs/32314809023)\n- Smoke Copilot Small — [§32314806549](https://github.com/github/gh-aw/actions/runs/32314806549)\n- Smoke Copilot MAI — [§32314804312](https://github.com/github/gh-aw/actions/runs/32314804312)\n\nLikely also affected (same run-ID/time cluster, not yet individually confirmed — verify before closing): 32314801400, 32314798663, 32314796269, 32314746588, 32314746662, 32314747000, 32314746697, 32314746781, 32314746796, 32314746805, 32314732816, 32314732184, 32314732334, 32314732431, 32314732660, 32314732376, 32314642769.\n\n### Probable root cause\n\nGitHub's artifact API is rejecting the literal name `activation` for `Create Artifact Container` (likely a reserved-word/naming-policy change on the Actions platform side, or a collision with an internal artifact name). `audit-diff` between two of the failed runs showed zero firewall/network anomalies and identical zero-token-usage profiles — ruling out a network/proxy cause and confirming this is a single systemic naming-validation issue, not per-workflow drift.\n\n### Proposed remediation\n\n- Change the artifact name generated for the activation-upload step (e.g. `activation-${{ github.run_id }}` or `activation-<job-name>`) in the gh-aw workflow-generation code that emits the `.lock.yml` upload-artifact step.\n- Regenerate/recompile affected `.lock.yml` files and re-run one smoke workflow to confirm the upload succeeds.\n- Grep for other hardcoded single-word artifact names in the generator that could hit the same validation rule.\n\n### Success criteria / verification\n\n- A regenerated smoke workflow run completes the \"Upload activation artifact\" (renamed) step with `conclusion: success`.\n- No new `Create Artifact Container failed: ... is not valid` errors appear in subsequent 6h failure-investigator windows.\n","labels":["agentic-workflows","bug","automation"],"parent":"#aw_parent1","title":"[aw-failures] [P0] Artifact upload fails: \"The artifact name activation is not valid\" — smoke-test fleet outage"}}}

Create Artifact Container failed: The artifact name activation is not valid.\nRequest URL https://pipelinesghubeus12.actions.githubusercontent.com/.../artifacts?api-version=6.0-preview\n```\nFailure occurs in the `activation` job at the \"Upload activation artifact\" step — before the `agent` job ever starts (0 tokens spent).\n\n`audit-diff` between [§32314806549](https://github.com/github/gh-aw/actions/runs/32314806549) and [§32314804312](https://github.com/github/gh-aw/actions/runs/32314804312) (Smoke Copilot Small vs Smoke Copilot MAI, both failed): zero firewall/domain anomalies, zero token usage on both — confirms both runs died identically at the same infra step, not from workflow-specific drift. This is one systemic cause, not three separate bugs.\n</details>\n\n<details>\n<summary>Agent CLI failures — insufficient evidence</summary>\n\nAudit of [§32318213755](https://github.com/github/gh-aw/actions/runs/32318213755) (Daily Go Test Parallelizer) surfaced only `Agent execution exited with code 1` with no rate-limit, proxy, timeout, or auth signature in usage/rate-limit logs. Auto-Triage Issues run [§32317125168](https://github.com/github/gh-aw/actions/runs/32317125168) uses a different CLI (Pi) entirely — not the same signature, so not clustered together. Both P2, no action taken this cycle.\n</details>\n\n### Existing issue correlation\n\n- **No match** for the artifact-rejection cluster. Closest existing issue is #53262 (\"'evals' artifact not found — full run failure\") but that's a *missing* artifact at read time, not an API rejection of the artifact *name* at creation time — different failure mode, left open and cross-referenced only.\n- No other open `agentic-workflows` issue (#53935, #53130, #52726, #52459, #52502, #53619, #53263, #54072, #54094, #48838, prior reports #53933/#53129/#52570/#52395) references this signature.\n- No issues closed this cycle — no fresh evidence obtained that any of them are fixed or stale.\n\n### Fix roadmap\n\n- **P0 — do now:** Rename or suffix the `activation` artifact so it passes GitHub's artifact-name validation (e.g. include run ID/job name in the name). Tracked in sub-issue below.\n- **P1 — none confirmed this cycle.**\n- **P2 — monitor only:** Watch for repeat `Execute GitHub Copilot CLI` / `Execute Pi CLI` exit-1 failures; open a tracked issue only once ≥2 runs share the same signature.\n\n### Sub-issues created\n\n- P0 artifact-name-rejection fix (linked below).\n\n**References:**\n- https://github.com/github/gh-aw/actions/runs/32314806549\n- https://github.com/github/gh-aw/actions/runs/32314804312\n- https://github.com/github/gh-aw/actions/runs/32318213755\n","labels":["agentic-workflows","bug","automation"],"title":"[aw] Failure Investigator Report — 2026-08-20 01:11 UTC (6h)"}}}
