- Line 94: Update the entry title and body in IDEAS.md to remove the obsolete
per-G artifact and DataFusion comparison guidance. Align the description with
tenant masks over the combined image and the scalar quad/sidecar reference,
ensuring it no longer instructs implementers to split the shared ordinal image
or target a MedCare-rs DataFusion comparator.
In @.claude/plans/spog-alpha-channel-v1.md:
- Line 86: Update the “Absent, by search” inventory in the relevant plan
paragraph to identify the AlphaMask::words() absence as historical, before
D-SPG-1, or revise it so it does not contradict the accessor added in alpha.rs.
Preserve the separate lgj_hop and AND3 findings.
- Line 166: Update the crosswalk and rung examples using mask_ternlog to either
explicitly label the expressions as pseudocode or use the declared four-argument
mask API (or mask_ternlog_assign). Ensure neither example presents a copyable
three-argument call to mask_ternlog::<IMM>.
- Line 93: Escape the pipe characters in the inline search expression within the
table row, changing the displayed expression to use escaped separators so
Markdown preserves it as a single cell.

MedCare-rs #620 (sibling session, merged the same day) is recorded as the first SpogTenants consumer — two examples, no src change — together with its 0.00 % cross-tenant is_a finding, which makes a CURIE→address resolver the prerequisite for gate (a)'s multi-tenant chain.

…s under F5 Two facts the rebase onto `main` (now carrying #1220) makes checkable, and both come out against what the board says. **The cited MedCare-rs shas do not exist.** `d64854b`, `c6a9095` and `6bf7764` are MISSING from every fetched `origin/*` ref of AdaWorldAPI/MedCare-rs, checked at main `9f9b7be` — i.e. AFTER both #620 and #621 merged, so this is not a "not yet merged" lag. `spog_masks` appears in no ref either. The work was done; it was never pushed. Marking it Shipped on an append-only board would make the claim permanent and unverifiable from public history, so the status cells are regraded **Shipped-unpushed** in place, with the check that produced the regrade written next to it. The measurements themselves are left exactly as the session that ran them reported — this corrects the STATUS, not the numbers. **F5 was written when no cross existed in the contract; one does now.** #1220 shipped `alpha_focus::AlphaFocus::{cell, matrix, unlooked, rung_reach}` — scalar `and`/`and_not`, no `ndarray`. F5's ruling is about the SIMD/ternlog cross and survives that literally. But `cell` and `unlooked` now exist in two places, and which one a consumer should reach for is not this spec's to settle: recorded as an open operator question rather than answered.

Update the numeric self-reference after the prepend.
The new entry adds 56 lines before the existing content. The preserved EPIPHANIES.md:899 reference now resolves 56 lines before its previous target. Update it to the current target, line 955, or replace the numeric reference with the cited entry heading.
Based on learnings: .claude/board/EPIPHANIES.md is a newest-first, append-only ledger, so prepended entries shift numeric self-references.

Use one full-classid oracle for the specification and dashboard.
G is graph_of(c), so a tenant mask can contain several full classids. Both records currently use node_rows_for_classid(G), which does not validate the OR-folded tenant population.

Define provenance validation for gate (d).
AlphaMask::and calls AlphaMask::zip, which checks only len. SpogTenants::tenant_mask returns an untagged AlphaMask, while AlphaOverlay stores no tenant or family identifier. Therefore, two same-length masks from different tenants can pass and without rejection. Define the seal layer and its provenance check, or remove the cross-family rejection claim.

Preserve the append-only board history.
The new MedCare-rs evidence is appended inside the existing D-SPG-2 and D-SPG-3 historical rows after the earlier Shipped-unpushed records. Add new newest-first entries instead. Keep prior entries unchanged, except for permitted Status and Confidence updates. This preserves the required audit trail.
Based on learnings: .claude/board/*.md files must remain append-only and newest-first.

…h move §5 rows This branch was written alongside two PRs that have since merged. Rebasing onto `main` makes their effect on this spec checkable, and it is not nothing: two deliverables change state, and neither change was visible from the PR bodies alone. Every claim below is measured on the merged trees. **D-SPG-8: Queued → SHIPPED.** MedCare-rs #621 registers `LanceTableProvider::new(ds, false, false)` at the production call site (`medcare-server/src/state.rs:945`) and pins it with a test that reads the schema of the table `build_session_context` ACTUALLY registered, comparing it against a hand-built identity-on provider over the same dataset — two-sided, so the silent half measures rather than asserts. Its own doc records the disable run that caught an earlier draft asserting against a provider the test had built itself. The gate this spec wrote for D-SPG-8 is met, at the site that matters. **D-SPG-5: Queued → PARTIAL.** Leg (i), the `domain_rung` squat this spec exists to retire, is gone — `origin/main` carries `domain_rung`/`rung_for` only inside a historical doc comment. Legs (ii)–(iv) are untouched, and the row now carries the count instead of the intention: 16 bare `AlphaOverlay` references in `backreference`, 15 in `medcare-nodesoa::alpha` — whose two writers still have zero callers outside their own module, so that leg migrates a writer nothing calls yet — and `frontier_dispatch` still dispatching without tenants. Two bare-overlay sites the row never named are added: `medcare-cohorts::graph_feed` and `medcare-soa::patient`. **The contract gained a cross of its own.** #1220's `AlphaFocus::{cell, matrix, unlooked, rung_reach}` is scalar `and`/`and_not`, so F5 — which rules on the SIMD/ternlog cross — survives it literally. What it does create is `cell` and `unlooked` in two repos, which this spec is not the place to adjudicate: it is recorded as an open operator question in the F5 row and in §8, not answered. Board hygiene in the same commit: STATUS_BOARD rows, plan §5 rows, plan §8 item 7, LATEST_STATE bullet. Gates: append-only OK (9 files), citation-decay 0 new, supersession index current. No Rust changed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_013S6AQs95K3rHymE3kAqZay

What
Operator mandate 2026-09-07: "probe autoattended autonomous decision making until you get MedCare-rs SPOG alpha channel to work" — with two constraints (no Lance row ids, sealed batch per cycle; the S3 bakes are not per-domain files) and the mid-turn instruction to migrate the hand-rolled MedCare alpha onto the #1198 contract alpha.
Two commits:

Frozen decisions F1–F9: domain = a mask over the combinedall-lanes.soaimage (eq_u32_strided_to_maskper G,ORper domain, TUI fence for the horseshoe lanes); G = the contract'sgraph_of; rung byte = attention rung only; the ternlog cross lives one crate out of the zero-dep contract;cycle = Lance version + 1; explicit mask ABI traversal, never VSA; the hand-rolled MedCare alpha drivers migrate ONTOAlphaTunnel+SpogTenants+merge().

mainBoth PRs this branch was written alongside have merged, and the branch has
been rebased onto
main(a4f661a, which now carries #1220). Rebasing madetheir effect on this spec checkable; two §5 deliverables change state, and
neither change was visible from the PR bodies alone. Everything below is
measured on the merged trees.
LanceTableProvider::new(ds, false, false)at the production call site (medcare-server/src/state.rs:945) and pins it with a test that reads the schema of the tablebuild_session_contextactually registered, against a hand-built identity-on provider over the same dataset. Two-sided, so the silent half measures. Its own doc records the disable run that caught an earlier draft asserting against a provider the test had built itself.domain_rungsquat this spec exists to retire, is gone (origin/maincarriesdomain_rung/rung_foronly inside a historical doc comment). Legs (ii)–(iv) untouched, now on the board as a count rather than an intention: 16 bareAlphaOverlayreferences inbackreference, 15 inmedcare-nodesoa::alpha— whose two writers still have zero callers outside their own module — andfrontier_dispatchstill dispatching without tenants. Plus two bare-overlay sites this spec never named:medcare-cohorts::graph_feed,medcare-soa::patient.One open question this PR records rather than answers. #1220 landed a cross
of its own in the contract —
alpha_focus::AlphaFocus::{cell, matrix, unlooked, rung_reach}, scalarand/and_not, nondarray. F5 rules on theSIMD/ternlog cross and survives that literally. What it does create is
celland
unlookedin two repos, and which one a consumer should reach for is notthis spec's to settle: it is noted in the F5 row and in §8 as an open
operator question.
Two board claims were regraded, then re-regraded. D-SPG-2/3 were marked
Shipped against MedCare-rs shas that existed on no pushed ref — checked at
MedCare-rs main
9f9b7be, i.e. after both #620 and #621 merged, so not mergelag. They were regraded Shipped-unpushed; the branch has since been pushed
(
spog_masksis now onorigin/claude/medcare-rs-continue-ufsazd) and the rowsare back to Shipped. The measurements were never in question — only whether
public history could check them.
