R81.C verification — docs/5-time/roadmap.md reconcile

Scope recap

Reconcile stale R76/R77 state in docs/5-time/roadmap.md per R81 Wave 1 manifest (.agents/spawns/r81-kappa-phase-1-wave-1/manifest.md):

R76 section “in progress” → “SEALED” with merge commit ae0b78ec
New R77 pages-finish section with PRs #165–#171 + symbolic Merkle 38a39b7d…
Phase 1 section status → “in progress — Wave 1 opened 2026-04-19”, kickoff → “R81 (active)”
Footer updated: date → 2026-04-19

Evidence

Grep checks

$ grep -n "in progress" docs/5-time/roadmap.md
# (zero live hits on R76 row; any remaining "in progress" matches post-edit are on Phase 1+)

$ grep -n "^## R77\|pages-finish" docs/5-time/roadmap.md
141:## R77 pages-finish round (post-Phase-0 hygiene, 2026-04-19, SEALED)

$ grep -n "^updated:" docs/5-time/roadmap.md
7:updated: 2026-04-19

All three checks pass.

Scope constrained exactly as contracted — single-file edit, non-structural. No Phase 2+ sections touched, no ADR link edits, no layer-table alterations.

Quality gates (2026-04-19)

Run from .worktrees/claude/r81-c-roadmap-reconcile on HEAD 7f7d3e81 against main 77e579b8:

Gate	Command	Result
Build	`npm run build`	✓ exit 0
Lint	`npm run lint`	✓ exit 0
Test (first run)	`npm test`	1084/1085 — pre-existing `startup — subprocess smoke` flake under full-suite load (documented in `MEMORY.md`; not an R81.C regression — R81.C touches zero `src/` code)
Test (rerun)	`npm test`	1085/1085 green across 26 suites in 25.77 s

Zero code deltas in R81.C ⇒ a regression in src/__tests__/startup.test.ts is structurally impossible. Rerun clears the flake as documented.

Invariants (from contract §3)

I1: Single-file edit (docs/5-time/roadmap.md only)
I2: No structural changes (heading hierarchy, layer tables, phase-section order, ADR links all unchanged)
I3: Non-regression on tests (1085/1085 on rerun)
I4: R76 section accurately reflects seal state (merge SHA ae0b78ec, PR #164, PR range #152–#164)
I5: New R77 section accurately reflects post-seal reality (7 PR links #165–#171, merge SHA 77e579b8, symbolic Merkle 38a39b7d6425d9d0bcc993799bbc72f9202e4afd6fad21769dbb864e4ab8cdc6)
I6: Phase 1 section marks R81 as active (not “planned”)
I7: Footer date reflects edit day (2026-04-19)

Follow-ups / carry-forward

None from R81.C itself. All 4 edit targets from contract §2 land cleanly.
Adjacent observation (out of R81.C scope): the ## R76 bridge round title drift was detected at the top of the R81 Phase A observation — R81.C closes it. Similar drift may recur as future rounds seal; a post-seal “roadmap reconcile” co-task should be the standard R{N}.Z tail in future rounds.
