bvandeusenandClaude Opus 5	aee24c9c1c	feat(retrieval): a tuned number carries the space it was measured in (#4104) ... Milestone 416 step 6. A retrieval floor is a cosine similarity, which only means something inside one embedding model's geometry over documents cut one particular way. Change either and every floor on the install keeps applying while describing nothing — and nothing anywhere says so, because the scores simply come out different and the bar goes on cutting. `CHUNKER_VERSION` already solved this for documents: stamped per row, so the backfill re-embeds precisely what is stale. The same idea, applied to the numbers: - `calibration_stamp()` — embedding model + document shape, one definition. TWO fields, never a fused string (rule 149): a mismatch has to say WHICH half moved, because they call for different responses. - `retrieval_tuning_events` gains `embedding_model` / `shape_version` (migration 0104), stamped on every write. Nullable and NOT backfilled — "unstamped" is the honest answer for a row written before this existed, and it reports as `stale: null`, never as fine. - `current_settings` reports calibration per dial: tuned rows from their event, untouched dials from the registry default's own stamp. - `retrieval_surfaces` and the Settings panel show the mismatch. The panel renders ONLY when something is stale, so seeing it at all is the signal. - `migrate_floor` / `migrate_retrieval_floor` answers "a path for thresholds to be inherited by the next model so that they don't have to recalibrate a lot": the raw cosine cannot cross models, but the PERCENTILE it represented can. Measure what fraction of a surface's logged calls the old floor admitted, re-score those queries under the current model, take the value admitting the same fraction. Dry run by default; applying writes an ordinary tuning event with the arithmetic in its reason. Nothing auto-retunes. A stale stamp says a number is no longer a measurement; it does not say what the number should be, and #4102 measured the one case where the statistic and the correct action pointed opposite ways. The load-bearing test is an ABSENCE: no chat-model identifier may appear anywhere in the calibration path. Claude produces none of these scores, so a Claude upgrade must trigger nothing — a false alarm here teaches the operator to ignore the real one on the day bge-small becomes bge-base. Backup v17 carries both columns, unfilled on the way out and on the way back: a round trip must not turn "we don't know" into a stated fact.

bvandeusenandClaude Opus 5	ca49a46c23	feat(retrieval): the model moves its own floors, and says why (#4102) ... Milestone 416 step 4's write half. `retrieval_surfaces.py` made the six push arms describe their `{floor, budget}` the same way; this adds the three MCP tools that let the model READ that and change it, and the backup sections that carry the reasons. The operator's decision, which this implements: "the floor should be chosen and adjusted by the model using it… the user should be able to touch it but the model should be the thing handling it 9 times out of 10." WHY A REASON IS REQUIRED, AND WHY THE TOOL ARGUES AGAINST PERCENTILES The milestone originally listed self-tuning as a non-goal on one measured case, and that case is now the tool's docstring rather than a prohibition: `report_preference` logged 69 consecutive declines with the refused record 0.0006 under the bar, and every percentile said "lower it". The refused record was rule 77 "Extract intent from loose phrasing" matched against a query about report layout — a false positive. Lowering would have attached that rule to every completion report ever written. What separated the statistic from the correct action was OPENING the record. So `tune_retrieval` refuses a blank or perfunctory reason, tells the caller to read `retrieval_telemetry(near_miss_samples=5)` and the record ids it names, and carries that 69-decline example — an abstract warning loses to a number. The non-goal that survives is *statistical* auto-tuning; nothing here reads a percentile and picks a value. BACKUP (v16), which is what CI caught `retrieval_tuning_events` was neither backed up nor excluded, and #2293's guard said so. It is backed up: `settings` already carried the numbers, so dropping this would restore an install with six moved dials and no argument for any of them — precisely the state the table exists to prevent, and worse now that the model is the one moving them. One `_retrieval_tuning_event_rows` builder called from both exporters (snippet #2851); `user_id` travels because a restore has to remap it, which is why the row builder is not the model's `to_dict()`. `surface` is a registry name rather than a foreign key, so the history survives a restore into an install whose ids all differ.
