+# Token bake warning
+
+Tag `v0.2.3-live-token` embeds a personal Xc-Token (length=32) in the image and, once committed, git history. This is a security risk.
+
+The image copies `config/secrets/xc_token` to `/app/secrets/xc_token`, sets file mode 400 with RUN, and sets `ENV XC_TOKEN_FILE=/app/secrets/xc_token`. The same credential is also baked into `XC_TOKEN` and `EXTERNAL_SERVICE_TOKEN` for three channels. Resolution order is `XC_TOKEN_FILE` → `XC_TOKEN` → `MODELHUB_XC_TOKEN` → `EXTERNAL_SERVICE_TOKEN`.
+
+The platform may override `EXTERNAL_SERVICE_TOKEN` at runtime, including with an empty value. The file is checked first so this override cannot wipe the file channel. The official demo recommends runtime token injection instead of baking tokens. This requested bake is an explicit exception. Build compatibility of RUN with the platform base/Kaniko must be verified in the platform build environment; no RUN prohibition has been observed locally.
+
+Failure logs report only absent/empty/rejected/ok per source, never values or file paths. Successful resolution logs only the source name.
+
+Set `ALLOW_LIVE_SUBMIT=0` to stop live submissions. Rotate the token if the repository or image is exposed.

+# Live gate update — 2026-10-17
+
+Queue snapshots accept integer or ASCII digit-string totals and derive model/GPU pairs from modelId and gpuType across all statuses. Nonterminal tasks count toward the queue gate. Invalid or incomplete snapshots stop submissions with ledger_rebuild_failed.
+
+Token resolution prefers EXTERNAL_SERVICE_TOKEN, XC_TOKEN_FILE, XC_TOKEN, then MODELHUB_XC_TOKEN; empty and placeholder credentials are skipped. Missing credentials hold even with injected submit clients. Each allowed cycle logs only the selected source name. Xc-Token remains the authentication header.
+
+Offline generators read local adapt evidence only. Input candidates: A=60, B=296; after pending and banned filters: A=46, B=296, total=342. Verified reuse A precedes other A, then B. Baked ledger: 206 pairs and 28 blocked models. Baked JSON ships through COPY src/; .dockerignore does not exclude src/data/*.json.
+
+The ledger merges remote pairs, baked pairs, and persisted model|gpu pairs. Explicit do-not-resubmit models are blocked on every GPU; other models may use the next mapped, unsubmitted GPU in candidate order. Reservations are written before task/add, including failed attempts. Legacy model-only state files fail closed and require offline migration. Startup rebuild logs source counts; each prospective submission refreshes remote identities and queue count.
+
+Validation: make test passes 59 tests using stdlib only. Added coverage for pair dedupe and restart persistence, baked blocks, next-GPU selection, missing tokens, token source logging, digit-string totals, invalid totals, and baked candidate ordering/filtering. SIGTERM uses a mocked HTTP server and real subprocess signal without network calls. Dockerfile FROM unchanged. No git commit, push, tag, live probe, build-config call, or live submission performed.

+# Token file bake fix
+
+Host verification showed a valid credential (length=32), while production logged missing/invalid_token without a successful source line. This indicates production resolution had no usable credential. A runtime override of EXTERNAL_SERVICE_TOKEN or dropped token environment settings is the likely cause; the exact platform behavior remains unverified.
+
+The Dockerfile retains its original FROM and EXTERNAL_SERVICE_TOKEN, adds the identical XC_TOKEN value, copies config/secrets/xc_token to /app/secrets/xc_token, applies mode 400 using RUN, and sets XC_TOKEN_FILE=/app/secrets/xc_token. The original staged file remains length=32, no newline, mode 600. A narrow .dockerignore exception makes this file available to COPY while excluding other config files.
+
+Resolution order is XC_TOKEN_FILE → XC_TOKEN → MODELHUB_XC_TOKEN → EXTERNAL_SERVICE_TOKEN. The three baked channels are the file, XC_TOKEN, and EXTERNAL_SERVICE_TOKEN. Empty or rejected sources fall through. Failure diagnostics expose only fixed status labels; successful resolution logs only the source name.
+
+Validation: make test passed all 63 tests. Coverage includes file-first precedence with competing valid aliases, empty EXTERNAL_SERVICE_TOKEN falling through to the file, alias fallback order, missing credentials holding without submission, and probe/log secrecy. Static checks confirmed both baked ENV values match the file without printing values.
+
+Docker is unavailable locally, so image build, RUN support under the platform base/Kaniko, runtime file readability, and production recovery remain unverified. RUN chmod is included as requested; no observed Kaniko rejection justifies removing it. No live calls, commit, push, or tag were performed.
