chore(scripts): restore PR #65 (Q8_0 default + --target flag) lost in ht rewrite

[marksverdhei]

Summary

Epoch #86 task 3 (bench-dflash.sh drift check) surfaced this: PR #65 ("scripts(dflash): switch default bench target to Q8_0 + --target flag") was merged 2026-06-04 19:39 (merge commit `09b2124f`), but its content is missing from the current `origin/ht` tip. The script on ht still has the pre-#65 state — `TARGET=...gemma-4-31B-it-Q4_K_M.gguf` hardcoded, no `--target` flag, no `DFLASH_BENCH_TARGET` env var.

Likely cause: the 2026-06-04 ht history rewrite happened around the same time and didn't carry PR #65's diff through the 8-commit consolidation. (Spot-checked PRs #52, #54, #55 from the same window — those are all still present under different commit hashes, so this is genuinely the one that fell through.)

Fix

Cherry-picked `2079a61de` ("scripts(dflash): switch default bench target to Q8_0 + --target flag") directly onto ht. Same diff Markus originally approved; no other changes.

Test plan

• `git cherry-pick 2079a61` clean (no conflicts).
• Post-pick `bench-dflash.sh` has Q8_0 default, `--target PATH` flag, `DFLASH_BENCH_TARGET` env var, `DFLASH_BENCH_DRAFTER_DIR` env var, and the VRAM-math comment block.
• (post-merge) re-run bench-dflash on a Q8 target to confirm the lower default still works.

Audit follow-up

Suggest tagging `ht-pre-rewrite-2026-06-04` (already exists per memory) as the canonical reference for "what content was present pre-rewrite" — so future rewrites can sanity-check against this list. Filing as a low-priority observation rather than a PR.

Retracting — false positive. My local origin/ht was stale at the time I ran the ancestry check; after a fresh fetch + pull, origin/ht IS at 09b2124fb which includes the original PR #65 merge commit. The script already has the Q8_0 default and --target flag.

This is exactly the failure mode feedback_local_vs_origin_branch_check was written to prevent — I checked against local refs without fetching first. Updating the memory note to reflect that the cherry-pick was unnecessary.

Apologies for the noise; deleting the branch.
