[LEARN-02] Show hardness on Coordination cards and retain actual model/effort for completed Deliveries #5273

Work level: Delivery · Track: Active delivery · Intended Status: In progress

Owner

Root coordinator integrates and owns native adoption; hardness5273 owns source, tests and the same source chain. Independent source review follows the frozen candidate.

Done when

1. Coordination Project 3 stores a versioned Delivery hardness category and shows it on cards, including explicit Unknown. Categories derive from the accepted LEARN-02 rubric without conflating routing safety floors or missing scores with measured difficulty. Dimension scores and classification provenance remain recoverable.
2. Closed Deliveries retain the actual model and reasoning effort that worked them, preserving worker/critic roles and multiple execution identities. Requested routing and observed execution remain distinct; historical missing facts stay Unknown. Authoritative evidence supports every backfilled value.
3. New dispatch/completion recording and maintained card projection keep values current. Closing or archiving preserves durable provenance on the owning issue. Existing closed items receive evidence-based backfill within the qualified complete selected population, with coverage and gaps reported honestly.
4. The maintained schema/view migration and guarded writer preserve existing enrollment, fields, values, view settings and installed automation. Relevant tests, independent source review, exact-head CI, actual native card readback and visible-field verification establish adoption; source merge alone is insufficient.

Current deliverable

Source accepted through PR #5275, merged on 2026-11-03 as 5c85692721c45ee929fab4f6e600ac3226e3b631. Protected main has the exact reviewed/tested tree 8ff62fa379379416e0147837dd8b1362db8011f5. Independent review passed the cumulative provenance guards and coherent native report producer/consumer path. All 65 corrected original CI runs passed on attempt 1; 91 native checks passed and five were skipped by explicit event guards. All ten required contexts passed for the exact head and GitHub Actions App. Post-merge original CI is being observed separately. No LEARN fields, card views, historical metadata, installed caller, routing policy or timer has been activated by source acceptance.

The v1 lexical hardness categories remain provisional and unvalidated across models and reasoning effort. Source/unit/native mechanism checks do not establish measurement validity. #5276 now carries the priority validity assessment; no learned routing or validated-difficulty claim follows from this merge.

Next action

Prioritize #5276's cross-model/effort validity assessment before Root decides native category rollout. Separately prepare normal coherent publication and qualify the actual installed compiled migration caller. Before native adoption, record exact hub-helper discovery: the Coordination Project3 lifecycle owner runs the Python recorder/projector from an explicitly selected protected accepted FS-GG/.github checkout, verifies origin and exact revision, and uses absolute helper paths; Drivers do not package these helpers. Product consumers delegate this Project3 boundary to the hub owner. Source-helper adoption is distinct from installed migration CLI qualification.

Then, only under Root's separate selected effects, refresh the complete qualified native metadata population and exact field/view preimages; create/read back additive fields, supported visible-field projection and evidence-based current/closed Delivery metadata. Preserve all enrollment, values, view identities/configuration and existing automation. Retain missing historical facts as Unknown, verify actual cards and durable owning-issue provenance, and carry archived-history gaps explicitly. Publication, installed adoption, metadata backfill and visible-card verification remain acceptance work.

Blocked on

Source integration is complete. Native annotation adoption requires normal publication, actual installed caller qualification and separately selected guarded native effects. Native hardness category rollout additionally awaits Root's disposition after the #5276 validity assessment. Historical execution gaps remain Unknown. The Delivery remains OPEN / In progress.

Acceptance evidence

Baseline #5249 / PR #5250; accepted source PR #5275. Corrected original CI: always-gates, coord-github, and tested checkout / coherence. All 65 corrected runs passed attempt 1, with exact-head required checks and matching reviewed/tested tree. The original failed cohort and its determining errors were retained; no rerun replaced it. Source acceptance does not satisfy the native adoption or hardness-validity remainder.
