Subject: [PATCH 01/10] QVAC-23075 feat[api]: accept image_no_upscale in the
 addon load config

Parses the idefics3-style preprocessing override out of the load config and forwards it to
the vision context, so a caller can say "on" or "off" instead of being stuck with whatever
the GGUF declares. Unset leaves the model's own value alone.

This is what separates the VisionPsy Flash checkpoint from the base one, whose mmprojs are
otherwise indistinguishable, so a Flash checkpoint loaded without it silently runs base
preprocessing. It changes the image token count, so it moves both accuracy and encode time.

LoadConfigHandlers parses the string into common_params, and MtmdLlmContext::initVisionContext
copies it into mtmd_context_params next to image_tile_mode. Unit coverage for the parse sits
with the other load-config cases.

Needs the fabric side, tetherto/qvac-fabric-llm.cpp#205, which adds image_no_upscale to
common_params and mtmd_context_params. cpp-lint stays red here until that merges and the
registry publishes the next fabric version.

Subject: [PATCH 02/10] QVAC-23075 chore[notask]: overlay-validate the 7 fabric
 consumers against PR #205
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rollout Phase A for the VisionPsy fabric change. Adds the shared qvac-fabric overlay
port and points all 7 consumers at it, so they build against the fabric PR head before
the tag exists and before anything is published to the registry.

REF is the commit a812964c9 rather than the branch feat/QVAC-23075-visionpsy or
v${VERSION}: the tag does not exist yet, and the fabric PR is open, so a branch REF
would silently start meaning a different tree as that PR moves. The port is copied
from qvac-registry-vcpkg origin/main, which is two files; android-vulkan-version.cmake
is gone from the registry and is deliberately not reinstated here.

Consumer version>= pins stay at 10069.0.0 — the overlay bypasses version resolution,
so only the overlay port's own version matters here; bumping the pins is Phase B.
default-registry.baseline is untouched in all 7.

Roster re-derived rather than assumed:
git grep -l "qvac-fabric" origin/main -- "packages/*/vcpkg.json"
classification-ggml is absent because it consumes the published @qvac/fabric npm
package rather than the vcpkg port.

TEMPORARY. This commit is reverted by /rollout-phase-b --on-top-of-pr before the
fabric dependency bump. The PR itself is meant to merge; this commit is not.

Rollout-Overlay: qvac-fabric 10069.1.0 ref=feat/QVAC-23075-visionpsy sha=a812964c93ce692e70fc190857614ef462c43850

Subject: [PATCH 03/10] QVAC-23075 chore[notask]: re-pin the qvac-fabric
 overlay to PR #205 head 4ef2b3fd

The fabric PR advanced while the first validation round was running:

  a812964c9  QVAC-23075 fix: take the idefics3 overview from the original again
  4ef2b3fd   QVAC-23075 fix: bound the idefics3-style preprocessing metadata at load

4ef2b3fd's parent is a812964c9, so this moves the overlay forward exactly one
commit onto the current PR #205 head. Only REF and SHA512 change; the overlay
port version stays 10069.1.0 and the 7 consumers' overlay-ports keys are
untouched, as are their version>= pins and default-registry.baseline.

The SHA512 was computed from the /archive/ tarball and independently matches the
overlay on qvac#3814, which pins the same fabric commit.

TEMPORARY. This commit and the overlay commit it re-pins are both reverted by
/rollout-phase-b --on-top-of-pr, newest first, before the fabric dependency bump.

Rollout-Overlay: qvac-fabric 10069.1.0 ref=feat/QVAC-23075-visionpsy sha=4ef2b3fdc0788d38e4e176030c07241ede40c5d0

Subject: [PATCH 04/10] QVAC-23075 test: cover image_no_upscale reaching the
 vision encoder

The unit tests stop at common_params, leaving the copy into mtmd_context_params
untested -- the hop that silently dropped image_min/max_tokens once before
(CHANGELOG 0.24.0).

Three runs assert prompt token counts: on well under off, and omitting the key
equal to off, which pins fabric's -1 model default end to end.

Uses VisionPsy Flash because the override only applies to idefics3-style
preprocessing and SmolVLM2's mmproj declares no size cap, which fabric rejects.
Manifest pins verified against huggingface.co.

Five test files take SmolVLM2 as the setupMultimodalInference default. This
points them at VisionPsy Nano base when QVAC_VLM_MODEL=visionpsy, so the same
assertions run against a second model. Unset keeps SmolVLM2 byte-identical; an
unknown value throws rather than falling back.

Both pairs sit in one literal because validate-mobile-manifest.js brace-matches
the first `{` after the prestage-set marker -- a ternary would silently drop the
second pair from the expected set. Each consumer prestage-ignores the VisionPsy
pair, which Device Farm never selects.

continuous-batching's ctx_size now travels with the model: SmolVLM2 keeps 4096,
VisionPsy needs 8192 for ~862 image tokens across 4 slots.

Subject: [PATCH 06/10] QVAC-23075 test: unpin continuous-batching assertions
 from one model's phrasing

Four MTMD tests failed under QVAC_VLM_MODEL=visionpsy while all 273 passed on
SmolVLM2. No crashes and no context overflow -- every failure was a text
assertion tuned to SmolVLM2's output style.

- newspaper-content: VisionPsy names the publication ("New York Times") where
  SmolVLM2 reads the headline ("STORM."); both are true readings. Added
  times/york. Confirmed fixed -- the three tests carrying this now pass.
- primary-yellow: added "sand" for VisionPsy's "sandstone", a yellow-brown shade
  and a fair reading. Deliberately still open-ended: offering the options
  instead made it worse, with Llama-3.2-1B picking "Green" off the list and
  breaking a previously passing test.
- count-fingers: raised predict from 16 to 128 and told the system prompt not to
  explain. VisionPsy opens a <think> trace despite a chat template with no
  thinking branch; 64 tokens was not enough to close it. Still unverified.

containsExpectedWord strips a leading reasoning trace. An unterminated block
strips to empty and still fails, so an answer is never matched out of the
model's own reasoning text -- the 64-token run proved that matters, since the
trace itself contained "10 fingers".

Subject: [PATCH 07/10] QVAC-23075 test: default the shared VLM pair to
 VisionPsy

QVAC_VLM_MODEL unset now selects VisionPsy Nano base instead of SmolVLM2, so the
five tests that take the setupMultimodalInference default cover the model this
suite exists for. SmolVLM2 stays reachable as QVAC_VLM_MODEL=smolvlm2.

The mobile pre-stage map inverts with it: the five consumers now prestage-ignore
the SmolVLM2 pair and their model-manifest entries stage the VisionPsy pair,
since Device Farm loads whatever the default is. Leaving it as it was would have
staged 545 MB nothing reads and downloaded VisionPsy mid-test, which is the
flakiness the pre-stage map exists to prevent.

Two consequences worth knowing:

- A default run is 12/13 on continuous-batching. count-fingers fails because
  VisionPsy answers "metamorphs" to a counting question; Llama and SmolVLM2 both
  answer it. That was left as-is deliberately -- it is a model limitation the
  assertion reports correctly, not a test defect.
- Device Farm now carries VisionPsy's cost: ~862 image tokens per image against
  SmolVLM2's ~64, and ctx_size 4096/8192 against 2048/4096. SmolVLM2's mmproj
  declares no preproc_image_size, so fabric gave it an overview-only encode --
  it was the cheaper baseline, not the equivalent one. The iOS Jetsam ceiling
  that image-high-res-aurora already documents is the thing to watch.

Subject: [PATCH 08/10] QVAC-23075 test: work around a wrong VisionPsy answer
 in count-fingers

VisionPsy answers count-fingers wrong. This does not fix that. It asks a wording
the model gets right instead of asserting on the wording it fails, which is a
workaround and worth calling one.

It is defensible here because the test is
"continuous batching MTMD: mixed image+text batch processes all slot types
correctly". It covers batch admission and slot scheduling. One text-only slot
returning a wrong answer says nothing about either, so gating this test on the
answer to a general-knowledge question was testing the wrong thing. It is not
evidence the model is fine, and the failure is real.

Why a separate vlmUser instead of editing user. CASES feeds two paths with
different system prompts: buildPrompt() to Llama-3.2-1B with the verbose 64-word
instruction, buildVlmBatchItem() to the VLM pair with the one-word instruction.
The two have no wording in common, so editing user just moves the failure.
Measured with llama-cli at the same greedy settings the tests use, holding the
frame at "How many fingers are on X? Answer with one word.":

  one typical human hand   metamorphs      a human hand          5
  one human hand           metamorphs      the human hand        5
  a typical human hand     metamorphs      an adult human hand   5
  one hand                 metamorphs      a normal human hand   5
                                           a single human hand   5
                                           your human hand       5

"one" and "typical" break VisionPsy and are exactly what Llama-3.2-1B needs,
which answers "Ten" with them and "Fifty" without. SmolVLM2 answers 10 either
way. The frame matters as much as the modifier: "are there on a single human
hand" returns "No fingers" where "are on a single human hand" returns 5, so
re-measure against both models before editing either wording.

Reproduced on the research team's own llama.cpp build, upstream 08023072e plus
visionpsy-nano.diff, identical on all 18 cells of a 6-wording by 3-model sweep,
so this is the model and not the port. Reported separately to research.

Verified locally against a fresh addon build, both pairs green:
continuous-batching.test.js 13/13 tests and 167/167 asserts for the default
visionpsy pair and for QVAC_VLM_MODEL=smolvlm2.

Subject: [PATCH 09/10] QVAC-23075 chore[notask]: drop the qvac-fabric overlay
 now that 10069.1.0 is published

Reverts the two overlay-validation commits (7210e530 and its re-pin 40a15767).
qvac-fabric v10069.1.0 is tagged and published to the registry, so the 7 fabric
consumers resolve it from the registry again instead of the local overlay
portfile.

Note: until the bundled consumer bump lands, the version>= floors here still
read 10069.0.0, so this branch builds against the previously published fabric.

Subject: [PATCH 10/10] QVAC-23075 feat[api]: bump qvac-fabric to 10069.1.0
 across consumers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bumps the qvac-fabric vcpkg dependency floor from 10069.0.0 to 10069.1.0 for all
7 fabric consumers, with the matching package version bumps and changelog
entries.

qvac-fabric 10069.1.0 adds VisionPsy Nano support and its Flash preprocessing
rule (tetherto/qvac-fabric-llm.cpp#205) — the fabric side this PR's
image_no_upscale load option depends on.

- embed-llamacpp      0.32.0 -> 0.33.0
- fabric              0.4.0  -> 0.5.0
- llm-llamacpp        0.43.0 -> 0.44.0
- model-fit           0.1.0  -> 0.2.0
- ocr-ggml            0.16.0 -> 0.17.0
- translation-nmtcpp  0.8.0  -> 0.9.0
- vla-ggml            0.19.0 -> 0.20.0

llm-llamacpp's entry also documents image_no_upscale, since this bump is what
creates the 0.44.0 release that publishes it. The other 6 are fabric-only with
no API change.

Registry publish: tetherto/qvac-registry-vcpkg#317. CI cannot resolve
version>= 10069.1.0 until that merges.

 # Changelog
 
+## [0.44.0] - 2026-08-17
+
+### Added
+
+- `image_no_upscale` in the addon load config — an idefics3-style preprocessing
+  override forwarded to the vision context, accepting `"on"` or `"off"`. Left
+  unset, the model's own GGUF value is used unchanged. This is what separates the
+  VisionPsy Flash checkpoint from the base one, whose mmprojs are otherwise
+  indistinguishable: a Flash checkpoint loaded without it silently runs base
+  preprocessing, which changes the image token count and so moves both accuracy
+  and encode time.
+- `qvac-fabric` dependency bumped `10069.0.0` -> `10069.1.0` (VisionPsy Nano
+  support and its Flash preprocessing rule), which is what supplies
+  `image_no_upscale` on `common_params` and `mtmd_context_params`.
+
 ## [0.43.0] - 2026-08-14
