Conversation
The default model declares `pooling_mode_lasttoken` in 1_Pooling/config.json and its ONNX graph carries a matching lasttoken_squeeze + normalize path, exposed as a second `sentence_embedding` output. Vera reads output 0 (`last_hidden_state`) and mean-pooled it, so every vector the default model produced was pooled a way the model was never trained for. Using the graph's own `sentence_embedding` as the oracle, last-token pooling reproduces it exactly (cos 1.0000 on every probe text) while mean pooling lands at cos 0.59-0.66 and reorders results. `LocalEmbeddingPooling` had no way to express this, which is why the misconfiguration was unreachable by configuration as well as wrong by default. Adding the variant also unblocks evaluating Qwen3-Embedding, F2LLM and C2LLM class models, which all pool the same way. Three details this needs to be correct rather than merely different: - The unpadded token is found by scanning for the highest set position in the attention mask. Counting set bits is right only under right padding. - `defaults_for_source` fell through to `Default`, so correcting jina would have repooled every custom repo too. The generic fallback is now explicit and stays on mean. - Preset identities now carry the pooling mode. Without that, an upgraded install would query mean-pooled rows with last-token vectors instead of reporting a stale index. `vera setup` freezes the resolved model config into ~/.vera/config.json and that copy outranks the preset, so the fix would never have reached an existing install. `repair_stored_defaults` upgrades exactly the old jina preset on load and leaves any customised config alone.

The literal mean|cls|last-token put unescaped pipes inside a table cell, splitting it into extra columns. Every sibling row already uses the <placeholder> form, so this matches the table rather than diverging from it.

Correcting something I overstated in the PR description and in #92. I wrote that adding last-token pooling "unblocks evaluating Qwen3-Embedding, F2LLM and C2LLM class models". I have now actually run the available exports against Vera's two-input feed instead of reasoning from their file lists, and that claim is too strong.
So pooling was one blocker for those models, but not the only one, and removing it does not make them loadable today. What this PR does establish is narrower and still worth having:
Nothing in the fix or its tests depends on the claim I am walking back. The correctness evidence is the exact match against the graph's own Separately, and more usefully: On CoIR it scores 0.7110 with full 10-task coverage. The incumbent has run only 2 of the 10 CoIR tasks, so no comparable mean exists for it. I am not proposing a default change here, just recording a verified candidate for #66. |

Not fixing this, and the reason is specific rather than a general objection to provenance.
The ambiguity is real: a user who explicitly chose mean for jina writes a config byte-identical to the legacy default, so intent genuinely cannot be recovered from the value.
But persisting a marker means writing to config.json, and writing to that file on a load path is what broke a released install during this PR. repair_stored_defaults originally sat inside load_saved_config, whose result feeds every save helper, so the repaired value was persisted as a side effect of unrelated commands and a released vera 1.0.0 then aborted at startup on unknown variant `last-token` for every command. Fixed in 6bc9676 by keeping the repair in memory, and again in 0d5634f when vera repair turned out to persist it through a second path. A marker written by a new binary is one more field an older one has to tolerate.
The escape hatch exists without a schema change: VERA_LOCAL_EMBEDDING_POOLING=mean wins over the stored config, because set_env_value skips keys already present in non-force mode.
One correction to my own earlier statement of that: vera setup, vera backend and vera repair all call apply_saved_env_force, which overrides the shell value for the rest of that process. So the hatch holds for ordinary commands and not for those three.
The narrower half of your point is intended behaviour and is stated in the doc comment: only the exact historical preset tuple is upgraded, and anything differing in any field is treated as deliberate. 650b51d pins that literal to frozen values precisely so a future constant change cannot silently widen or narrow it, with a tripwire test.
A schema version is the right long-term answer for config migration generally. I would rather propose it as its own PR than infer it here.
![coderabbitai[bot]](https://avatars.githubusercontent.com/in/347564?s=60&v=4){kind=small}
The repair ran inside `load_saved_config`, which is also the base of every write: each save helper loads that struct, edits one field and writes the whole thing back. So the repaired `pooling` was persisted to ~/.vera/config.json as a side effect of commands that have nothing to do with embedding models. Config is machine-global, not per-install. Once a new build rewrote "mean" to "last-token", the installed released vera 1.0.0 on the same machine could no longer start at all: Error: failed to parse persistent state: ~/.vera/config.json: unknown variant `last-token`, expected `mean` or `cls` Running one build bricked the other. That also contradicts the claim that the repair happens purely at load time. `load_saved_config` is now a plain read, so what flows into `save_config` is byte-identical to what was on disk, and the repair moves to the two places that consume the model config at runtime: `saved_local_embedding_model` (behind `vera repair`) and the `apply_local_embedding_env` call that seeds the process environment. Both readers still see last-token pooling; the file keeps whatever `vera setup` wrote, and only `vera setup` or `vera repair` change it. The two regression tests redirect VERA_HOME at a temp dir, seed the legacy jina block, and pin both halves: the file is unchanged after a real save cycle, and the runtime readers still yield LastToken. Each was verified by reinjection.

Investigated rather than applied, and the premise does not hold as stated.
std::env::set_var racing a concurrent std::env::var is not what the safety contract describes. std's unix env implementation serialises its own accessors behind a static ENV_LOCK: RwLock<()>, taken for read by getenv/environ and for write by setenv/unsetenv. The documented hazard is readers outside std::env: a C getenv from a dependency, ToSocketAddrs, localtime_r reading TZ, or a spawned Command reading the environ global outside the lock.
So the question is whether any such reader runs in this test binary. I enumerated all tests with --list and checked reachability from a #[test], not mere presence in the file:
commands/doctor.rsandcommands/uninstall.rshave no#[cfg(test)]module at all.- The
main.rstests only callCli::parse_from; clap is built without theenvfeature andcli.rshas noenv =attributes, so parsing reads nothing. - The
update_check.rstests call only pure helpers; none reaches theVERA_NO_UPDATE_CHECKread. - The
setup.rstests call onlyshould_prompt_api_config, a pure predicate. resolve_backendreadsVERA_BACKENDonly after an early return; its single caller passespotion_code: trueand never gets there.- No test body spawns a process, resolves a hostname, or touches
TZ.
There is also a repo convention: vera-core does exactly this in config.rs:630 and retrieval/search_service.rs, each with a lock scoped to its own tests. Adding a third, differently-shaped mechanism in state.rs alone would make the codebase less consistent rather than more.
What would change the answer, and what to watch for in review: any new vera-cli test that reaches config_path/vera_dir/load_saved_config or calls from_env() without taking VERA_HOME_LOCK, which is a correctness flake rather than UB; or any test that spawns a process, resolves a hostname, or touches TZ, which is real UB. If that happens the fix is to promote VERA_HOME_LOCK to a crate-level env_lock() matching the vera-core pattern, not to add a serial_test dependency.
c94dc80 did correct the set_process_env safety comment, which previously claimed an invariant these tests violate. Happy to be shown a reader I missed.
The repair had two independent call sites, so a third runtime reader of local_embedding_model could add itself without it and silently reinstate mean-pooling on a last-token model. One private helper makes the repaired value the only one a reader can obtain. The repair still stays out of load_saved_config, which every save helper writes back through.

`from_directory` built its config as `..Self::default()`, and `Default` is `jina()`. Once jina moved to last-token pooling, every model loaded from `--embedding-dir` or `VERA_LOCAL_EMBEDDING_DIR` silently inherited last-token pooling too, even though Vera has no preset for those repos and cannot know how they pool. Vectors pooled the wrong way are not comparable, so the index degrades without any error. `from_huggingface_repo` already routes through `defaults_for_source`, which sends `Directory` to `generic_defaults()` (mean). Route `from_directory` the same way so the two constructors agree.
`model_identity` short-circuits for both `jina()` and `coderankembed()`, but only the jina half was asserted. A regression that dropped CodeRankEmbed from that branch, or dropped pooling from the preset format, would have passed the suite and left CodeRankEmbed indexes silently stale after a pooling change. Assert the exact preset form rather than only that two identities differ: comparing a mutated preset against the original passes on its own once the mutation pushes it into the generic branch, which proves nothing. Verified by reinjection that each assertion fails when the behaviour it covers is broken.

Working through the remaining findings on this PR. Fixed:
|
`repair` sourced its embedding model from `saved_local_embedding_model`, the accessor that applies the in-memory pooling repair, and handed it to `configure_backend`, which persists whatever it is given. A legacy `"pooling": "mean"` config was therefore rewritten as `"last-token"`, and an older Vera on the same machine then aborted on every command because its `FromStr` knows only `mean` and `cls` — the exact brick the in-memory repair was introduced to avoid, surviving in the one command called "repair". Unlike `vera setup`, nobody asked this command to change a pooling mode. Source the raw stored value instead. The corrected pooling still reaches this command's runtime through `apply_saved_env_force`, which repairs on the way to the process environment, and asset prefetching never reads `pooling`, so nothing downstream loses the fix.
…nstants `repair_stored_defaults` built its comparison value with `Self::preset`, which fills `onnx_file`, `tokenizer_file`, `embedding_dim` and `max_length` from the live `EMBEDDING_*` constants. The doc comment above it claimed the value stayed pinned; it was pinned against `generic_defaults()` only, and moved with every constant. That makes the migration silently self-disabling. Raising `EMBEDDING_MAX_LENGTH` from 512 to 8192 for VeraTools#67 gives the comparison value `max_length: 8192`, a real pre-fix `config.json` still carries 512, equality fails, and every pre-fix install stays mean-pooled forever with no error. The same holds for any rename of the preset ONNX or tokenizer file. Move it to a named `legacy_jina_before_pooling_fix` built from frozen literals, and add a tripwire test asserting the live constants still describe that historical file, so the next constant change fails loudly with instructions rather than quietly narrowing the migration to nothing.
`repair_leaves_customised_and_unrelated_configs_alone` customised two fields, pooling and `max_length`. The `max_length` line is what made it pass: drop it, leaving the single-field customisation a user actually produces with `--embedding-pooling mean`, and the test fails, because a mean-pooled default repo with nothing else changed is byte-for-byte the config an older `vera setup` wrote by itself. So the test read as proof that a deliberate pooling choice survives when it proves no such thing. Cover the one-field case explicitly and assert what actually ships: it is repaired. The migration has no field left to tell the two apart, and sparing this user would mean sparing every pre-fix install, so overwriting it is the accepted trade rather than a bug — recorded here so the next reader does not "fix" it. The neighbouring comment now says which case it really covers.
…ange `assert_ne!(jina.model_identity(), mean_pooled.model_identity())` did not test what it looked like. Setting `pooling = Mean` breaks full struct equality with `Self::jina()`, so the clone falls out of the preset branch of `model_identity` and renders through the generic one. The two strings differ because of the branch change, not because pooling is part of the preset identity, and the assertion holds even with pooling removed from that branch. Assert the exact preset form instead, matching `coderank_preset_identity_records_its_pooling`, which was already written this way. Reverting the preset branch to `self.display_name()` now fails this on the identity itself rather than on an adjacent property.
The `set_process_env` safety comment claimed Vera only mutates the process environment during single-threaded CLI startup. This PR's tests call it from libtest's thread pool, so the stated invariant no longer holds as written. Describe the real one: production is single-threaded at that point, and the tests are sound because every test touching those variables holds `VERA_HOME_LOCK` for its whole body. A future test that skips the lock is the actual hazard, so the comment now says so. The `LastToken` doc named Qwen3-Embedding and F2LLM as models requiring it. Both are causal-LM ONNX exports Vera cannot feed at all — measured, Qwen3 declares 59 inputs and F2LLM 3, and both fail the two-input feed — so naming them beside a capability being added reads as a claim that this unblocks them. It does not. Keep the note to jina, and to the `1_Pooling/config.json` value that is the actual source.
