Session Handoff — 2026-05-05-c

Trigger: post-PR-#1753 canonical-truth sync (sync PR opened from docs/sync-post-1753-dap-read-model-dogfood; merge commit recorded after merge). Filename suffix follows docs/dev/HANDOFF_TEMPLATE.md Usage Notes (handoff-YYYY-MM-DD-c.md) — third same-day handoff after the morning handoff-2026-05-05.md and the post-#1751 handoff-2026-05-05-b.md.

Session Goal

Sync ICN canonical project truth (docs/STATE.md, docs/PHASE_PROGRESS.md, docs/DOCUMENT_REGISTRY.md, latest handoff) with PR #1753 (docs(ideas): add read-model dogfood slice for Democratic Authority Primitives (idea-0020)) — which merged on 2026-05-05 at 22:08 UTC, after the post-#1751 sync PR #1752 had already declared canonical state. This is a narrow doc/control-plane sync; the next pre-RFC architecture move remains deliberately unselected so the next session can pick from updated canonical truth.

Decisive Test

Can a new organizer enter the system mid-cycle, switch into the right scope, see the summit's current phase, understand what was decided, know what is blocked, receive their obligations, trace why they exist, and continue the work without private oral history?

Unchanged from the 2026-04-15 handoff. Every move is judged against whether it makes that more answerable.

Final State (Verified)

main HEAD

e7a24239 docs(ideas): add read-model dogfood slice for Democratic Authority Primitives (idea-0020) (#1753)

Open PRs

Open coordination/control issues (not implementation)

All three are unchanged from the post-#1751 handoff (handoff-2026-05-05-b.md).

Validators (actual observed outputs from this session)

• git diff --check — clean.
• python3 ops/ideas/validate_ideas.py — ok (20 idea(s)).
• python3 .github/scripts/compliance_linter.py — clean (no violations).
• python3 docs/scripts/doc_control_check.py --repo . --registry docs/registry.toml --strict — passed; the markdown corpus under docs/ advanced by +1 (this new handoff). Pre-existing yaml-mismatch / classification-debt warnings on unrelated files (docs/ai/*, docs/architecture/INSTITUTION_PACKAGE_BOUNDARY.md, docs/design/*, docs/development/testing/governance-proof-layers.md, docs/onboarding/*, docs/planning/*, docs/plans/*) remain as baseline noise; none implicate STATE.md, PHASE_PROGRESS.md, registry.toml, DOCUMENT_REGISTRY.md, or this handoff file.
• docs/DOCUMENT_REGISTRY.md regenerated via python3 docs/scripts/doc_control_check.py --repo . --registry docs/registry.toml --write-document-registry docs/DOCUMENT_REGISTRY.md to reflect the +1 corpus delta from this handoff. Strict doc-control check rerun green after regeneration.

Rust verification (cargo check --workspace) was not run as part of this sync — this PR's stated validation is docs/python-only. The Rust workspace was last confirmed compiling at the morning preflight on 2026-05-05 against pre-#1751 main; that is not a current-state claim for e7a24239.

What Changed

1. Recorded #1753's landing in canonical truth

PR #1753 (docs(ideas): add read-model dogfood slice for Democratic Authority Primitives (idea-0020)) merged at 2026-05-05 22:08 UTC as commit e7a24239 after the post-#1751 sync (#1752, merged 20:30 UTC) had already declared canonical state. The handoff docs/dev/handoff-2026-05-05-b.md and the post-#1751 sync edits to STATE.md / PHASE_PROGRESS.md therefore listed the DAP read-model composition slice as the most directly named candidate next move — language now stale relative to main.

2. STATE.md truth-sync (docs/STATE.md)

• Last Reviewed: 2026-05-05 unchanged (same calendar day as post-#1751 sync).
• Added a 2026-05-05 (post-#1753) sync-edit comment block at the top, immediately before the existing 2026-05-05 (post-#1751) block. Records the single landing (#1753), the slice's idea-0019-orthogonal composition claim, the receipt-class candidates as slice-local-only (not committed as canonical), and explicit non-claims (no runtime, no schema, no contract URN, no ADR, no RFC, no implementation issue, no Phase 2 status change, no formal NYCN pilot, no live federation, no live cloud sync, no K3s/DNS/Forgejo mutation, no private-data handling).
• Appended #1753 as the top row of the "Recently merged (since 2026-04-15)" table.
• Updated the "Current status (2026-05-05 snapshot)" paragraph: removed the DAP read-model composition slice from the open candidate enumeration (it has now landed as #1753); recorded that idea-0020 now has both pieces of its idea-refinery surface (framing brief #1751 + read-model fixture-walk dogfood #1753); preserved the receipt-backed promotion language (a read-model fixture walk does NOT satisfy receipt-backed promotion thresholds); enumerated the remaining candidate next moves descriptively only, with class (1) removed and renamed (a)-(g): (a) DAP runtime dogfood emitting at least one receipt under ADR-0026 for one DAP primitive; (b) idea-0019 runtime dogfood emitting at least one ProcessTransitionReceipt class; (c) idea-0019 visibility/privacy-boundary run; (d) idea-0019 accessibility-gate ProcessGateResult; (e) idea-0019 Q1/Q3/Q4 triage; (f) one of the DAP §17 follow-up framing briefs (CCL hook-point catalog; expert/advisory across institution types; conflict object model connecting ConflictDisclosure to idea-0016/ADR-0029; federation tally semantics composing RepresentationMandate with #1609; delegation runtime gated on #1632); (g) control-plane cleanup including unresolved/stale review-thread hygiene.
• Inserted a new "Democratic Authority Primitives read-model fixture-walk dogfood" bullet block at the very top of "What landed since Phase 1 (Charter Engine)", recording the slice's composition claims, receipt-class candidate posture, and the §16.1 strict-RFC-promotion reminder. The existing "Democratic Authority Primitives framing" block (#1751) is preserved verbatim immediately below it.
• Extended the References block with ops/ideas/dogfood/democratic-authority-primitives-mvp.md and pointed the latest-handoff reference at this file (docs/dev/handoff-2026-05-05-c.md).

3. PHASE_PROGRESS.md truth-sync (docs/PHASE_PROGRESS.md)

• Last Updated: 2026-05-05 unchanged.
• Added a 2026-05-05 (post-#1753) sync-edit comment block summarizing the landing, confirming Phase 2 status remains ⏳, and noting that the prior post-#1751 sync's most-directly-named candidate (DAP read-model composition slice) has now landed.
• Extended the Phase 2 deliverables list with one [x] entry crediting idea-0020 read-model fixture-walk dogfood — same scope discipline as the existing eight [x] framing/contract/dogfood entries: pre-RFC framing/refinery only, no runtime, no schema, no contract URN, no ADR, no RFC, no implementation issue. Added four [ ] entries naming the unstarted runtime dogfood, visibility/privacy-boundary run, accessibility-gate ProcessGateResult, and DAP open-question triage that the framing brief's §16.1 strict RFC promotion gate requires.
• Added a 2026-05-05 (post-#1753) entry to "Decisions Made" recording the dogfood landing, the orthogonal-to-idea-0019 stance, the unchanged Phase 2 partner gate, the [x] + four [ ] deliverables update, and the explicit "next move not yet selected" stance with the seven-class candidate enumeration consistent with STATE.md.

4. Registry refresh (docs/registry.toml and docs/DOCUMENT_REGISTRY.md)

• [docs."docs/STATE.md"] last_updated and last_reviewed already at 2026-05-05 from the post-#1751 sync — no change needed (same calendar day).
• No new explicit [docs."..."] rows were added in this PR. The new handoff under docs/dev/ participates in the merged registry/doc-control scan via the existing [[doc_path_defaults]] rule with prefix = "docs/dev/" — covered by the registry without a per-file overlay row. The DAP read-model dogfood slice committed in PR #1753 (ops/ideas/dogfood/democratic-authority-primitives-mvp.md) lives outside docs/; docs/scripts/doc_control_check.py only scans docs/**/*.md, so the dogfood slice is not subject to the registry / doc-control scan and is not covered by [[doc_path_defaults]]. That is the correct posture for ops/ideas/ artifacts (validated by ops/ideas/validate_ideas.py, not by the doc-control plane).
• Regenerated docs/DOCUMENT_REGISTRY.md (human summary companion to registry.toml) via python3 docs/scripts/doc_control_check.py --repo . --registry docs/registry.toml --write-document-registry docs/DOCUMENT_REGISTRY.md to reflect the corpus delta after adding this handoff: Markdown files under docs/ advances 775 → 776 (only the new handoff under docs/dev/; the dogfood slice lives under ops/ideas/ and is intentionally outside the doc-control scan, so it does not contribute to the count). descriptive count advances accordingly. No truth-class reassignments.

5. New session handoff

• This file (docs/dev/handoff-2026-05-05-c.md) replaces docs/dev/handoff-2026-05-05-b.md as the latest handoff. The morning docs/dev/handoff-2026-05-05.md and the post-#1751 docs/dev/handoff-2026-05-05-b.md are preserved verbatim as historical artifacts; all three share the date and are disambiguated by their suffix per docs/dev/HANDOFF_TEMPLATE.md Usage Notes.

What's Open

The next session picks one of these from updated canonical truth. None is selected here. The next session must choose deliberately from updated canonical truth, not auto-pilot.

• DAP runtime dogfood slice — the next artifact called for by the slice's own promotion gate (and by the DAP framing brief's §16.1). A second dogfood slice that runs against a real or fixture-equivalent gateway and emits at least one receipt under the existing ADR-0026 envelope for one of the named DAP primitives. The framing brief's §16.1 names a ConflictDisclosure accept receipt and a MinorityReport recorded receipt generically; the dogfood artifact references ConflictDisclosureAcceptedReceipt and MinorityReportRecordedReceipt as slice-local class candidates without committing them as canonical. Producing any one as a real receipt would be sufficient evidence; all are not required.
• idea-0019 runtime dogfood slice — one of four #1748 acceptance gates. Emits at least one of eight named ProcessTransitionReceipt classes (ProcessSessionOpenedReceipt, DeliberationEntryRecordedReceipt, DecisionRecordedReceipt, ActivationCrossedReceipt, MutationPlanRecordedReceipt, MutationAppliedReceipt, EvidencePacketProducedReceipt, ProcessGateResultReceipt) under the existing ADR-0026 envelope. Required for receipt-backed promotion of idea-0019 to RFC.
• idea-0019 visibility/privacy-boundary run — one of four #1748 acceptance gates. A real run with redaction in evidence export, walking a DeliberationEntry visible to body A but not to body B.
• idea-0019 accessibility-gate ProcessGateResult on a real surface — one of four #1748 acceptance gates. Produced through docs/design/ORGANIZER_MEMBER_ACCESSIBILITY_GATE.md checklist applied at PR time on a real surface.
• idea-0019 open-question triage — one of four #1748 acceptance gates. At least one of Q1 (ProcessTargetRef polymorphism), Q3 (DeliberationEntry kind taxonomy), or Q4 (HumanDecisionSet vs proposal/vote) resolved or explicitly deferred in writing.
• DAP §17 follow-up framing briefs — pre-RFC, decompose-only. Listed in the DAP brief: CCL hook-point catalog; expert/advisory across institution types; conflict object model connecting ConflictDisclosure to idea-0016/ADR-0029; federation tally semantics composing RepresentationMandate with #1609; delegation runtime gated on #1632.
• Control-plane cleanup, including unresolved/stale review-thread hygiene if inspection confirms it; pre-existing yaml-vs-registry drift on docs/ai/*, docs/architecture/INSTITUTION_PACKAGE_BOUNDARY.md, docs/design/*, docs/development/testing/governance-proof-layers.md, docs/onboarding/*, docs/planning/*, docs/plans/* is named here as a possible candidate but not selected.
• NYCN steward-facing communication-groups directory tool (NYCN #33) — verify status before reading; not in this repo. Carried forward from the post-#1751 handoff.

Unsafe Assumptions

• This sync trusts that PR #1753's dogfood slice and idea-0020 row update are themselves internally consistent; the slice was merged less than a few hours before this sync. Its content was not re-audited line-by-line during this sync (the post-#1751 handoff and PR #1753 review are the audit record).
• The "Open PRs" section trusts gh pr list --state open --limit 20 at the time of this sync. Dependabot may open additional dev-dependency bumps before the next session.
• docs/strategy/NYCN_PHASE_2_PILOT_REHEARSAL_GATE.md is referenced as the canonical Phase 2 gate; its content was not re-read in this sync (only its name was).
• The pre-existing docs/ai/*, docs/architecture/INSTITUTION_PACKAGE_BOUNDARY.md, docs/design/*, docs/development/testing/governance-proof-layers.md, docs/onboarding/*, docs/planning/*, and docs/plans/* doc-control-check warnings are treated as baseline noise; none was introduced or aggravated by this sync.
• Receipt class candidates ConflictDisclosureAcceptedReceipt, MinorityReportRecordedReceipt, and FacilitatorSummaryRecordedReceipt are slice-local class candidates referenced in the dogfood artifact at the right transition points. The DAP framing brief's §16.1 names ConflictDisclosure and MinorityReport receipts generically without attaching concrete class identifiers; the slice does not commit any of these names as canonical, and this sync does not promote them to canonical either.
• Rust workspace status against e7a24239 is not independently confirmed in this sync. The morning preflight verified cargo check --workspace against pre-#1751 main (21bb5a14); that is a stale verification for current HEAD.

Next Move

1. Open this sync PR — docs(state): sync Democratic Authority Primitives read-model dogfood landing against main from docs/sync-post-1753-dap-read-model-dogfood.
2. Address any AI/Copilot/Claude/Codex review findings as merge-gating per #1744 policy. Distinguish substantive findings from infra/quota terminal failures before merging. Classify any flaky CI failures as unrelated infra and rerun once before touching code.
3. Merge the sync PR. Pull main.
4. In a fresh session, the operator picks one of the candidate next moves from "What's Open" above. The user's standing guidance is:
   • Do not auto-pilot to DAP runtime dogfood, idea-0019 runtime dogfood, schema work, RFC promotion, ADR work, implementation work, NYCN work, website work, or new architecture without explicit user direction.
   • The DAP runtime dogfood is the most directly named candidate (the slice's own promotion-gate next-artifact, and the DAP brief's §16.1 strict RFC condition), but it is not auto-selected by this sync; the operator confirms before starting.
   • Per the post-#1751 handoff's standing guidance (still in force): do not start runtime dogfood, schema work, RFC promotion, ADR work, implementation work, NYCN work, website work, or new architecture without explicit user direction.
5. Whatever the next session picks, it operates against canonical truth current as of e7a24239 (or whatever HEAD is after this sync merges).

Architectural Decisions

No architectural decisions were ratified in this sync. The sync only records:

1. PR #1753 merged; idea-0020 Democratic Authority Primitives now has both pieces of its idea-refinery surface (framing brief #1751 + read-model fixture-walk dogfood #1753). Doc/control-plane and idea-refinery only.
2. The dogfood slice composes the six DAP primitive families end-to-end against the merged idea-0019 read-model fixture walk without modifying any kernel, runtime, gateway, ledger, governance, SDK, or contract file. The composition is the proof.
3. Receipt class candidates referenced in the dogfood (FacilitatorSummaryRecordedReceipt, ConflictDisclosureAcceptedReceipt, MinorityReportRecordedReceipt) are slice-local candidates only; they are not committed as canonical receipt class names.
4. Per ops/ideas/README.md § "Dogfood slice variants" and per the DAP framing brief's §16.1, the read-model fixture walk does NOT satisfy receipt-backed promotion thresholds; idea-0020 RFC promotion still requires runtime dogfood, visibility-boundary run, accessibility-gate result, and Q1 or Q5 resolved in writing.
5. The "next pre-RFC architecture move" remains deliberately unselected in canonical truth so the next session picks from a freshly synced surface rather than from stale post-#1751 candidate language.

Truth-Plane Notes

• Declared project truth: STATE.md and PHASE_PROGRESS.md updated in this PR; both are now current as of 2026-05-05 (post-#1753). Both retain the full record of the post-#1751 sync verbatim — this sync only adds a new comment block, a single table row, a paragraph rewrite, a new top entry under "What landed since Phase 1", a single [x] deliverable + four [ ] follow-up entries, a single Decisions-Made entry, and a References-list update.
• Implementation truth: no kernel, runtime, gateway, ledger, governance, or SDK code was inspected or changed in this sync. No cargo check/cargo build/cargo test was run as part of this sync. This PR's stated validation is docs/python-only; do not infer current Rust workspace status from this handoff. Any future cross-checking of compile state against e7a24239 should be re-run explicitly.
• Execution truth: branch docs/sync-post-1753-dap-read-model-dogfood carries this sync; main HEAD e7a24239; open PR queue limited to Dependabot at sync time plus this sync PR.
• Narrative truth: dogfood slice (ops/ideas/dogfood/democratic-authority-primitives-mvp.md), framing brief (ops/ideas/framing/democratic-authority-primitives.md), and idea-0020 row (ops/ideas/ideas.yaml#idea-0020) were read and confirmed to match the doc-sync language in this PR. NYCN-side narrative was not re-loaded.
• Known conflicts: none introduced by this sync. Pre-existing yaml-vs-registry drift on the noise-list paths above remains; that cleanup is out of scope here and is named in "What's Open" as a possible candidate next move (control-plane cleanup).
