hotplug: being plugged in IS the declaration — V3 for every plugged appid - #1216
Merged
Conversation
…appid Operator, 2026-09-07: "plug and play already has all the domains, you could simply make the global schema for all appids already in plug-and-play pattern activate V3 and be silent about all others... local quad usage must mint any V3 settings in plug and play, regardless of the settings here... otherwise I will spend weeks until I remember that we changed it here wondering why quad 4x24 stopped working." MY OWN SEAM WAS THE LOCKSTEP IT REPLACED D-BLOCKS-HOTPLUG-1 retired a central BUILTIN_READ_MODES row per consumer because adding a frontend must not mean editing the substrate. What I built instead held `const LOCO_READ_MODES` -- ONE HARD-CODED ROW PER SEAT (0x1717 alone), answered only when the plug covered every declared seat, `&[]` otherwise. That is the same central table one level up: adding a frontend meant adding a row, and every consumer outside 0x17XX got no reading at all. Both failures are silent AND remote. A missing row breaks no build; it surfaces later as a V1 tail where V3 was expected. The quad (LegacyOutlier::WideTriple, G2 4x24) is a carving of the 12-byte content-blind payload, which exists as such only under a V3 tail -- so "somebody scoped the reading in lance-graph" and "quad 4x24 stopped working in medcare-rs" are the same event, weeks and one repo apart. THE &'static DECISION WAS THE ROOT CAUSE I typed read_modes as &'static and argued it as "plug-and-play at COMPILE time: a reading is looked up, not computed". The consequence I did not weigh: a &'static table cannot be built per plug, so the authority can only return a table it holds ALL of -- which forces all-or-nothing, which forces a per-seat table. An aesthetic constraint on a type silently dictated the architecture underneath it. Now owned, so the authority answers for exactly the ids a plug declared. THE RULE Every classid in a plug gets ReadMode::PLUG_AND_PLAY_V3 (new, in the contract, named so a session can find it). ReadMode::DEFAULT stays V1: it is the canon zero-fallback for classes nobody plugged, and it is unreachable from a hot-plug lookup. `concept_override` remains for genuine per-class deviations -- blockly's seat reads Bootstrap because it stores an ogar-loco body, not cognitive tenants -- and it is a short list of EXCEPTIONS, not a roster of participants: a forgotten entry means "no override", never "no reading". The ownership guard survived, but only because it was checked: deriving from the plug initially dropped the consumer check codex flagged on #1207. Restored as `palette_seat_owner` -- a CLAIMED seat is its owner's, an UNCLAIMED one is plug-and-play for whoever plugs it, so a new frontend at 0x1718 activates and reads V3 with no edit here. FALSIFIERS (7 tests, both guards disable-verified) * restoring palette-only scoping turns a_capability_consumer_outside_the_loco_domain_also_reads_v3 red -- a MedCare-shaped plug of 0x0901/0x0902, the case this exists for * dropping the impersonation guard turns another_consumer_cannot_activate_a_claimed_seat red * an_unplugged_concept_is_silent_not_v3 holds the other end: "V3 for all plugged appids" must not become "V3 for everything" PROCESS NOTE. The first run of disable 1 PASSED and I nearly recorded the guard as non-load-bearing. cargo fmt had reflowed the closure I was patching, so the replace matched nothing and the disable was a no-op. The re-run asserts the anchor exists before writing. A disable that does not apply is indistinguishable from a guard that does not matter -- the second such instance this session. Gates: contract 1323 lib tests, ogar 82 lib + 7 new, contract clippy -D warnings + fmt clean, ogar fmt clean, citation-decay 0 new, supersession index byte-identical.

Codex P2 on #1216, and CORRECT -- it catches this arm contradicting the very ruling it implements. The palette path ran only when EVERY plugged id was 0x17XX. So a mixed plug -- an unclaimed palette seat alongside ordinary capability ids, e.g. `[0x1718, 0x0901]` -- failed that test, went WHOLE to resolve_hotplug, and came back UnknownClassid(0x1718), because that resolver is pinned to refuse a palette id by design (ogar-vocab's own `a_palette_classid_does_not_resolve_as_a_hot_plug`). A consumer that legitimately has both could therefore not activate at all -- against "every plugged appid reads V3", which is the whole point of this arm. No consumer mixes today, which is exactly why it would have been found late. Fix: partition rather than choose. Palette seats and capability ids answer to different authorities, so they route separately and the results merge; the reading covers the whole plug either way, because it is DERIVED from the plug rather than looked up. The ownership check moved above the split so a claimed seat is its owner's on either path. +2 tests, the second guarding the hole the partition could have opened: * a_mixed_palette_and_capability_plug_activates_and_reads_v3_for_both -- 0x1718 + medcare's 0x0901/0x0902 all read PLUG_AND_PLAY_V3. Anti-vacuity: asserts 0x1718 IS a palette seat and the other two are NOT, so the fixture provably straddles the partition; and asserts the capability half really went through the join (non-empty capabilities, and 0x1718 absent from the resolved concepts) rather than the join being skipped wholesale. * a_mixed_plug_carrying_someone_elses_seat_is_still_refused -- 0x1717 in a mixed plug from the wrong consumer is still UnexpectedConsumer. Disable-verified: restoring `resolve_hotplug(plug.consumer, plug.classids, ..)` turns the mixed test red, 8 passed 1 failed. Anchor asserted before patching, per this session's own lesson that a disable which does not apply is indistinguishable from a guard that does not matter. Gates: contract 1323 lib tests, ogar 84 lib (9 in this module), contract clippy -D warnings clean, fmt clean both crates, citation-decay 0 new.

…ment CodeRabbit minor on #1216, and CORRECT -- worse than its description. My anchor-based insert targeted `pub const DEFAULT: ReadMode = ReadMode {` without checking what preceded that line. A 20-line doc block did. So the insertion landed BETWEEN DEFAULT's doc comment and DEFAULT itself: * DEFAULT's entire doc -- the zero-fallback rationale, the RESERVE-DON'T- RECLAIM note, and the TEMPORARY 2026-06-15 POC block with its "flip value_schema back to Bootstrap HERE and in ClassView together" instruction -- reattached to PLUG_AND_PLAY_V3. * DEFAULT was left undocumented. * The orphaned text says `tail_variant = V1` while sitting on a constant whose tail is V3: directly contradictory public API docs, and the POC flip instruction pointed at the wrong constant, which is the part that could have caused a real mis-edit later. Fix: move the whole PLUG_AND_PLAY_V3 block (doc + value) to AFTER the complete DEFAULT item, so each doc attaches to its own constant. Also removed the blank line the move left between DEFAULT's doc and DEFAULT -- a doc comment separated from its item by a blank line does not attach. SECOND TIME THIS SESSION. The same mistake hit OgarAuthority on #1207 (`missing documentation for a struct`, fixed in 26ed7a8) -- there the compiler caught it because a lint fired; here nothing did, because the doc still attached to SOMETHING. Rule for the next insertion: when anchoring on an item declaration, check whether the line above is `///`; if so the anchor is inside another item's documentation, not before it. Verified: cargo doc -p lance-graph-contract emits 168 warnings, byte-identical to the count on the unmodified tree, and none in the touched line range. Gates: contract 1323 lib tests, ogar 84 lib, contract clippy -D warnings clean, fmt clean.

…ED; W1b is 0/5 TD entries + 1/7 files; M1–M27 reconciled; StepMask regraded in COMPONENT-MAP + guardrails; 0x1000 permanent in README + guardrails; tag-file errata CodeRabbit posted 12 findings against ddd3393. Each was verified against the tree; the substantive ones are corrected in the consolidated documents, the tag-file ones are answered by an append-only "Orchestrator errata" block at the end of each affected tag-file (the agent text stays verbatim — it is the evidence the inventory cites). Substantive (consolidated docs): - TD-NDARRAY-SIMD-GATHER: leading token PARTIAL, not SHIPPED. The API exists on scalar/avx512/neon but the x86 body is a scalar-loop polyfill by its own doc comment (`simd_avx512.rs:2833-2836`); the AVX2 gather the row requires is still open. Inventory §0/§1a/§5 and the EPIPHANIES numbers line now say 4/5 shipped + GATHER partial. - W1b: "0 of 6" mixed TD entries with files. There are 5 TD entries (TD-SIMD-SWEEP-W1..W5, 0 closed, W2 half-done) over 7 files (1 migrated — `types.rs` — 6 still raw). Inventory §0/§5 + EPIPHANIES numbers line. - ENTROPY-MILESTONES: the §3 breakdown omitted M1 (SHIPPED #628, gate tool queued) and §0 summed to 24. Now 9 shipped + 7 in-flight + 10 queued + 1 ruling-needed = 27. - STATUS_BOARD buckets: 575 of 592 rows classified; the 17 outside the nine leading tokens are now stated as unclassified (§0/§6), not implied away. - StepMask: COMPONENT-MAP still said BLOCKED/NEW "zero .rs matches" and the Sonnet guardrails vocabulary said "does not exist yet"; both regraded to `pub struct StepMask` (`crates/lance-graph-contract/src/step_mask.rs:40`, exported `lib.rs:241`, D-V3-W3a 2026-07-10). - 0x1000: the README five-sentence summary and the guardrails vocabulary row still called it temporary with a P4 retirement; both now carry the D-CCF-4 rescission (permanent monitor; P4 = operator checkpoint). - README doc-map row for the nexgen plan rewritten into complete clauses. - EPIPHANIES E-PLUG-AND-PLAY-…-1 Status line: "Fixed in this PR" was a context line from #1216 (commit 296e8b7), not this PR's change; it now names #1216 so the phrase does not go stale after merge (Status-line edits are the one permitted edit on a past entry). Tag-file errata (append-only, one block per file): the two truncated status_token cells with the full source values; the three concatenated headings (left as written so cited line numbers stay valid); the L–Z "15 files" list that has 16 entries and conflates three Status forms (re-verified per file: 10 no-header / 5 bold-wrapped / 1 bare); the 575-vs-592 bucket total; the W1b count; the "all five W1a shipped" overstatement; the retracted "no Pillar 6 in jc" claim; and 4609/11585 ≈ 0.40 (under half, not under a quarter). Gates: append_only_gate origin/main OK (9 files, none shrank); citation_decay --since origin/main 0 new / 147 pre-existing; SUPERSESSION-INDEX regenerated last, byte-identical.
