fix: bound unproven profile submissions and support single-worker takeover

Do not cache transient repository-list failures as empty weight sets.
Deduplicate normalized file paths without lowering reported file sizes.
Record whitelisted OOM evidence and bounded discovery diagnostics.

+## Single-worker takeover release 2026.10.26.1
+
+This release is intended to replace the competing workers, using all configured
+accounts in one process. Deployment must stop the old **agent process**, not
+its already-submitted validation tasks. Code cannot reserve capacity while an
+old worker continues to refill the same accounts. No live stop or cancellation
+is performed by installing this release.
+
+Keep `MODELHUB_STATE_SYNC_BRANCH=agent-state-accuracy-v2` to resume the newest
+checkpoint. Startup adopts the live waiting/running queue by task ID, without
+resubmission or attributing old work to the new version. It retains existing
+aggregate evidence; do not add the old branch's lifetime counters to it, which
+would double-count shared tasks. Historical tasks without encoding/provenance
+remain unknown. Queue cancellation remains disabled by default during takeover;
+existing tasks continue occupying capacity until the platform finishes them.
+
+Changes:
+
+- Recognize MLX metadata and top-level quantization configuration. Unknown packed
+  formats are deferred before submission to conventional backends. GGUF routes
+  retain their existing file-specific checks. No repository-name heuristics.
+- Persist an encoding signature so FP8 and INT4 variants of compressed-tensors
+  do not share a feedback-admission budget. Until the exact architecture,
+  encoding, GPU and framework has three successes and at least 50% observed
+  non-platform success, admit at most two pending tasks per group, including
+  tasks selected in the same concurrent batch. Deferrals are not failures or
+  permanent exclusions; completed tasks release the budget. This cap only
+  constrains already-eligible candidates; it does not create exploratory routes.
+- In the same success-confidence band, completion-speed estimates precede
+  community popularity when ordering candidates. Quality gates remain enabled.
+- Persist per-version terminal results and print `[feedback]` with success,
+  failure and pending counts. Unexplained failed statuses no longer pretend to
+  identify a parameter/template defect.
+- Close Git repository handles, throttle idle-cycle snapshots to once per
+  minute (intent/result writes stay synchronous), bound history traversal, and
+  rotate the disposable local clone after verified history compaction so old
+  unreachable objects do not accumulate indefinitely.
+- Log worker RSS/high-water memory and available cgroup memory counters once
+  per minute; retain the last sample and exit-time OOM counters with crashes.
+
+The thresholds above are conservative policy settings, not a guarantee of a
+particular success rate. Evaluate actual terminal outcomes separately from
+waiting tasks after deployment. A full inherited queue will not immediately
+produce new capacity just because the old agent process has stopped.
+
+## Accuracy release 2026.10.18.1
+
+This release rejects malformed YAML command arrays, including the observed
+`/opt/entrypoint.sh    - /model` executable error, even in restored cached
+official configurations. It preserves terminal compatibility errors when a
+log also contains transient platform resource messages. Framework scoring
+includes unresolved non-platform failures; sparse model-profile evidence is
+blended with eight prior observations instead of discarded below a threshold.
+
+For operation alongside the baseline agent, the new default state branch is
+`agent-state-accuracy-v2`. Do not override it with the baseline's `agent-state`.
+The separate branch starts its own checkpoint on first boot; it does not
+overwrite or migrate the baseline state. New submissions retain agent version,
+instance ID and platform strategy ID. Historical tasks are not assigned an
+invented version.
+
+`MODELHUB_COEXISTENCE_MODE=1` is the default: this agent does not run queue
+cancellation, including deterministic cleanup, because the accounts are shared
+with the baseline. Submission preflight remains enabled. Set this variable to
+`0` only when account-wide cleanup is intended; `--disable-queue-cleanup` still
+disables cleanup explicitly. The baseline agent is unchanged. Both agents share
+account capacity and platform deduplication; separate state does not reserve
+capacity or eliminate simultaneous submission races.
