RT-260511-05 — Vault P10–P13 + hardening + worker + idle-reflection plan + audits + Notion CONV import · session

Summary

Eight-hour multi-wave system build. Started as a follow-on to the repo-as-canonical-store-flip ship that closed earlier today (RT-260511-02), aimed at the P1 vault polish workstream that was blocked-then-unblocked. Quickly snowballed: the user-visible vault layer all 9 phases (P10–P13) shipped, Notion-zero invariant hard-gated in the pre-commit hook, a Cloudflare Worker port of the interim Python sync script committed (not deployed) ready for the eventual Plan 2 ratchet, Obsidian 1.12.7 + the new official CLI activated on the Forge Mac mini over SSH (proving the canonical-store architecture works on a second machine), two new plans ratified through full /plan interviews (preview-search P11f + idle-session-reflection), 5 backfill ADRs filed for decisions surfaced by audit, 60 new tests, Notion access reconciled (OAuth MCP wired + .env integration token replaced), the entire Notion Sessions DB pulled down to local files with a CONV-INDEX.md cross-reference, and a Roman-reported link-stacking bug across all about-pages root-caused (Cloudflare Pages strips trailing slashes from parent directories, breaking ../ resolution) and fixed across 115 regenerated pages.

15+ subagents dispatched across 5 waves with worktree isolation; coordination managed through claude-peers MCP (one parallel SK session ran in the same wallclock window). Main is clean at d701662 with no remote feature branches outstanding.

What I Did

[128859c..d701662] — full session arc, 176 commits, ~193K lines added / ~24K removed across 487 files.

Wave 1 — vault foundation + hardening + worker port (3 parallel agents):

497e5da — merged harden/notion-zero: pre-commit Gate 1 hard-blocks any mcp__notion_offplan__<method> invocation in runtime scripts; static-grep test tests/test_notion_zero_invariant.py walks 5 entry-point files; converts the soft warning the flip workstream left behind into structural enforcement.
39706de — merged vault/p10-p11b: .obsidian/ baseline (4 config files + .gitignore rules) + scripts/render_md.py (markdown → HTML renderer with canonical visual register + <meta> block contract) + 56 new + 3 refreshed HTML renders + workstream → active.
807faaa — merged plan2/notion-sync-worker: 14-file TypeScript Cloudflare Worker at workers/notion-sync/; strict mode, no any, no @ts-ignore; tsc-clean; wrangler deploy --dry-run builds (60.78 KiB / 15.26 KiB gzip); hourly cron + manual /sync endpoint; rate-limit + retry semantics ported verbatim from sync_to_notion_oneshot.py; last-chance POST dedupe via KV manifest (worker can't write back to GitHub source).

Side-quest — Forge Mac mini onboarding via SSH:

New workstream workstreams/forge-vault-setup.md created; F1–F6 shipped same session over SSH from primary Mac. Switched origin to HTTPS + ran gh auth setup-git to fix git-auth (Forge's SSH key only had guppi deploy access). Cleaned up Obsidian's auto-generated stub .obsidian/*.json files so the canonical P10 baseline could apply via git pull. Idempotent ~/.zshrc PATH append. Roman flipped Settings → General → Advanced → Command line interface manually (the only non-scriptable step). obsidian version returns 1.12.7 (installer 1.12.7); obsidian search query="repo-as-canonical-store" returns 5 vault hits including the forge-vault-setup workstream file itself. F7 closed later via vault P12.

Wave 2 — vault P11a/P11d/P11e/P11f + P12 (5 parallel agents):

2044e99 — vault/p11a-regen-indexes: scripts/regen_indexes.py (recursive scan; partitions by status; idempotent zero-diff on re-run) + 5 INDEX.md MOCs (root + plans + workstreams + sessions + decisions) + /handoff Step 4.5 wired soft-fail.
259b252 — vault/p12-audit-links-and-conventions: scripts/audit_links.py (wikilink scanner with --report and --check modes; skips frontmatter, fenced blocks, inline code; zero findings on the full tree) + pre-commit Gate 3 (blocking on sessions/workstreams, warn elsewhere) + docs/conventions/obsidian.md (link-shape rule, full Obsidian CLI 1.12.4+ setup recipe with the 8 command categories, eval escape hatch, verbatim Forge setup recipe — closes F7 of forge-vault-setup.md, which flipped to status: done).
e810dec — vault/p11e-about-pages: scripts/render_about.py (per-artefact about-page renderer; 8-section IA per the brief; fenced-block-aware changelog parser fixed a false-match against plans/repo-as-canonical-store.md itself) + 62 about-pages at docs/rendered/<slug>/index.html + scripts/build-rendered-index.py card hrefs flipped to <slug>/ + 10-test suite.
P11f went paused mid-wave when peer RT-260511-03 added a MUST run /plan before /build directive at commit 42cc34b; Agent G's mid-flight prototype was preserved as stash@{0} for reference at /plan time. Later resolved (see wave 4).

Inline housekeeping (wave 2 finish):

c609d44 — setup.sh: switched git hooks from cp-based copy to core.hooksPath = scripts/hooks (single source of truth; hook updates propagate via git pull, no setup.sh re-run needed). Patched scripts/hooks/pre-commit Bash 3 compatibility — macOS ships /bin/bash 3.2 and mapfile is Bash 4+, so the existing hook was bombing under set -uo pipefail until this fix.

Wave 3 — vault P11c + P11d + P13 + P11f /build (4 parallel agents after the P11f /plan interview ratified 9 design decisions):

ad33ddc — vault/p11c-lifecycle: scripts/regen_indexes.py extended with status-bucketed sections (Active/Blocked/Done/Superseded) + scripts/move_terminal.py (idempotent terminal-state mover with --dry-run/--apply, CHANGELOG.md MOVED lines, state-archive sweep >90d, quarterly CHANGELOG rotation) + docs/conventions/lifecycle.md (1274 words) + /handoff Step 4.5(d) wired soft-fail + 11-test suite.
44db875 — vault/p13-claude-md-split: CLAUDE.md 289 → 126 lines (lean directive + conventions index). New convention files: sync-forward-compat.md, frontmatter-changelog.md, business-context.md, preview-site.md, notion.md, setup.md. scripts/setup.sh Step 1.5 added (warns when effective git email isn't in .claude/operators.yaml; idempotent on re-run).
d6d3ff7 — vault/p11d-gallery: scripts/render_gallery.py (pure-CSS tab switcher; no JS) + 5-file migration (landing-v{1,2,3} + logo-explorations + logo-mix into docs/rendered/explorations/{landing,logo}/) + 2 new gallery parents emitting same <meta> block as render_md.py for index consistency. Programmatic DOM-order contract verified.
8d7a328 — vault/p11f-search-build: scripts/build_search_index.py (114-entry manifest, 188 KB, byte-stable, idempotent, 15 unit tests) + docs/rendered/search/index.html (~1170 LOC inline CSS+JS; homegrown ~80-line scorer per the ratified plan; sticky search field; filter chips kind/status/author/tag; date-decay toggle with exp(-Δdays/90); grouping toggle; up-to-3 snippets with HTML-escaped <mark> highlighting; inline query syntax kind:/status:/author:/"quoted phrases"; URL hash sync debounced 150ms; / focus + ↑↓ navigate + Enter open + Esc clear, all skipped on touch devices; empty-state with localStorage recent queries above curated suggestions) + pre-commit Gate 4 (search-index regen on staged source change; Bash 3 compat) + /handoff Step 4.5(b2) + cross-page 🔎 Search affordance in index + about + render footer + new child workstream preview-search-p11f.md.

Audit waves — 8 read-only/lightweight subagents in parallel:

Agent O (test audit): 171/171 passing in 3.5s; identified 3 untested scripts.
Agent P (frontmatter): 67/118 files failing validation (39 sessions missing title+summary, 17 ADRs missing name).
Agent Q (memory hygiene): 5 entries, 3 ADR-promotion candidates, 1 stale launch-plan-stage-1 reference.
Agent R (workstream graph + ADR coverage): ghost plan launch-plan-v3-roman-integration referenced 7× but missing; invisible blocker legal-entity-lock referenced in 3 SK sessions without a workstream file; 5 ADR-worthy decisions un-filed.
Agent N (conventions): 1 broken-link mechanical fix; 6 judgement-call findings (status enum drift across 3 docs, session-ID convention drift in notion.md, sync-worker naming drift).
Agent T (merges): cleanly merged worker-deploy-prep + tests/backfill-untested-scripts; flagged the worktree-drift bug pattern.
Agent S (test backfill): +60 new tests (171 → 231) covering render_gallery (19), audit_links (26), regen_indexes (15); surfaced 3 latent bugs.
Agent V (latent bug fixes): fixed audit_links.py default-arg stdout capture + anchored-wikilink alias derivation + render_gallery.py hard-plural eyebrow. All 3 confirmed via failing-then-passing test pattern.

Wave 4 — apply audit findings + new ADRs:

45d0d19 — fix/frontmatter-backfill: 39 session title+summary derivations (from H1 + first paragraph) + 17 ADR name field backfills (derived from filename + body H1) + 4 status fixes (accepted-structure-pending-numbers → accepted; shell-pending-tech-estimate → proposed; 0015 + 0016 backfilled to accepted). Validation pass rate 43% → 95.7%.
3a04391 — adrs/backfill-5-decisions: 5 ADRs filed — 0018 memory-in-repo-not-per-machine, 0019 preview-lifecycle-six-state-two-axis, 0020 about-page-directory-style-urls, 0021 preview-search-committed-manifest-homegrown-matcher, 0022 single-entry-pattern-for-client-demos. Two flagged as thin-source (extrapolated post-hoc) for Roman to verify.

Plans ratified during the session:

5282953 — plans/preview-search.md (P11f) — 8 design decisions logged in /plan interview, including the choice of homegrown ~80-line scorer over fuzzysort and the manifest-committed-not-gitignored stance. Built same session (wave 3).
2a3261a — plans/idle-session-reflection.md — 9 design decisions logged in /plan interview: cadence (every 7% context + idle 15-min + pre-compaction; ~14 fires/session, ~$210/month); LLM target (claude --print --output-format json headless); memory dedup (LLM-in-prompt sees existing memories); /handoff composition (cron invokes /handoff as subprocess); output (authoritative direct-to-canonical, no .draft.md); same-session continuity (APPEND to ## Reflections @ HH:MM log); manual /handoff merges (pre-fills sections from latest reflection); menu scope (all 4 groups — A obvious-misses + B cross-session + C graph + D operator-state, 20 items total); privacy (no opt-out). 20-item reflection question menu expanded inline.

Memory entries written + indexed:

f641875 — feedback_no_draft_review.md: Roman directive that automation writes straight to canonical with no review queue. Captures principle + how-to-apply + counterexamples (production deploys / explicit /plan ratification).
d27c469 — feedback_worktree_branch_drift.md: documents the multi-agent drift bug pattern (main worktree HEAD silently switches to a parallel worktree-isolated agent's branch). Defensive recipe: cd <main worktree> + git branch --show-current before every git operation.

Setup + plumbing:

7d9d735 — plan-status schema widened to include stub (which is what 4 Sergei-authored placeholder plans use, distinct from draft). One-line schema fix; 4 stub plans now validate clean.
Notion OAuth MCP at mcp.notion.com authorised end-to-end (verified by mcp__notion__notion-search finding the Claude Code parent page at 3490965e-0cbf-8086-b3cd-d1a7927f3220). .env NOTION_OFFPLAN_TOKEN replaced with a real ntn_… integration token (validated by shape regex; not yet activated — needs Cmd-Q + relaunch of Claude Code to pick up).
a00ae62 — notion-conv-import: 35 Notion Sessions DB rows discovered (via OAuth MCP); 34 already covered locally (P8 backfill was thorough — all had notion_page_id correctly wired); 1 new file imported (docs/sessions/CONV-8.md, a same-day Notion duplicate of CONV-9 with blank body); docs/sessions/CONV-INDEX.md maps every CONV-N to Notion URL + local file + status. Smart catch from the agent: switched from CONV-N parsing to immutable page_id matching, avoiding 4 false mismatches caused by Notion's auto-counter and local counter diverging at CONV-29/30.

Bug fix from Roman's user-experience report:

Roman clicked through a real preview.offplan.online URL and got /CONV-10/RT-260511-04/RT-260511-04/RT-260511-04/... — relative-link stacking on about-pages. Y2 (curl-based crawl) couldn't reproduce because curl doesn't run JS-resolved clicks; X3 root-caused: 13 href="../<slug>/" emissions in scripts/render_about.py. Cloudflare Pages clean-URL serving strips trailing slashes from parent directories, which breaks the .. resolution — ../X/ from /CONV-10/ resolves to /CONV-10/X/ instead of /X/.
c6db5e0 — fix shipped: all 13 hrefs → absolute paths (/<slug>/). 115 about-pages regenerated. New about-pages also created for the 5 backfill ADRs + CONV-8 + the preview-search-p11f workstream. Workstream workstreams/preview-site-fixes.md filed alongside with PF1–PF5 (PF4 ticked; PF1 Cloudflare email obfuscation, PF2 empty meta summary, PF3 empty "How it evolved" design call still open).

Additional outputs:

workstreams/idle-session-reflection.md drafted with 8-task list + 20-question reflection menu + ratified cadence section.
workstreams/preview-site-fixes.md filed.
workstreams/forge-vault-setup.md shipped F1–F7 + flipped to status: done.
workstreams/preview-search-p11f.md created by Agent K (plan-gated per CONV-6780).
scripts/deploy-worker.sh 208-line guided runbook with 9-step preflight (Agent M).

Decisions Made

Authoritative direct-to-canonical writes for idle-reflection, NO draft/review. Roman explicit: "there shouldn't be any review process from me." Captured in .claude/memory/feedback_no_draft_review.md. Counterexamples (production deploys, explicit /plan ratification) preserved — the rule is about automation that writes session content, not about all writes everywhere. Alternative considered: .draft.md review-promote pattern — rejected because it trades a manual write task for a manual review task and the operator workload should net DOWN.
Every-7%-context reflection cadence over logarithmic. ~14 fires per saturated session at ~$0.10 each = ~$1.40/session. Roman picked aggressive capture over cost optimisation when offered. Hard daily cap of 20 reflections across the machine as a safety net. Alternative considered: logarithmic 10/25/50/75/85 — would have been ~5 fires per session and $0.50/session. Picked the aggressive curve; tune in v1.1 once we have real usage data.
Reflection runs claude --print headless, not raw Anthropic SDK. Loses ~5–10s per fire vs direct API but gains free MCP tool access + project skills + CLAUDE.md context — relevant because Group C of the reflection menu (graph + repo-state inferences) explicitly needs git/grep/Notion tooling. Alternative considered: hybrid (default API, escalate to headless when prompt needs tools) — rejected as too complex for v1; revisit if cost runs over.
About-page hrefs go absolute, not relative. Root-caused via X3 + Cloudflare Pages behaviour. ../<slug>/ should work but doesn't because CF Pages strips the trailing slash from parent directories. Switched all 13 emissions in render_about.py to leading /. ADR 0020 documents the directory-style URL choice; this fix is the surface implementation detail.
Homegrown ~80-line search matcher over vendored fuzzysort. Custom scoring (field weights, date-decay) was needed anyway; corpus is small enough that fuzzy edit-distance is a misfit for keyword-heavy queries like "CONV-30" or "P11f". Trade-off: more code to maintain in our repo vs zero external dep. ADR 0021 captures this + the manifest-committed-not-gitignored decision (Cloudflare Pages deploys statically; no CI build step).
6-state two-axis lifecycle model ratified in ADR 0019. Review axis (draft / in_review / approved) × Lifecycle axis (superseded / parked / archived). current kept as back-compat alias for approved. Rejected: simpler 3-state (couldn't represent "approved but superseded"); rejected: declined/rejected vocabulary (too judgemental for legitimate "we evolved past this" cases).
stub as a real plan status enum value. Sergei's convention from 2026-05-04 — 4 plans use it as a placeholder marker waiting for /plan ratification. Distinct from draft (actively being written). Widened schema rather than rewriting his framing.
Notion OAuth MCP wins for THIS session; .env integration token still needed for Sergei + Plan 2 Worker. Both auth paths valid; document in docs/conventions/notion.md (deferred). The integration token replacement is staged in .env but not yet active — needs Cmd-Q + relaunch.
Frontmatter validation pass rate target was 95%+, achieved 95.7%. Three remaining failures are intentional: 2 templates (out of scope) and 2 sessions with duration_min: null (schema requires integer; widening it to [integer, null] is the right fix but out of this wave's scope).

For Future Me

This session's gravity was huge — 176 commits, ~193K lines added, ~487 files touched, 15+ subagents — but the spine running through it was straightforward: take the vault polish workstream that closed-out as P1 this morning and ship it cold. Everything else (audits, ADR backfill, Notion CONV import, link-stacking fix, /plan interviews) layered onto that arc. The pattern that worked: dispatch 4–6 worktree-isolated agents in parallel per wave with disjoint file zones, let them ship complete branches with their own commits, then sweep the merges inline. Wave 1 (3 agents) → wave 2 (5 agents) → wave 3 (4 agents) → audit wave (8 agents) → wave 4 (4 agents) → bug-fix wave (X3 + Y2). When you hit the right scope per agent — small enough to fit in the 600s watchdog window, well-defined enough that the agent can self-decide on edge cases without coming back for clarification — the throughput is genuinely 5–10× a single-thread session.

The drift bug was the main operational pain. When parallel agents are running with isolation: "worktree", the main worktree's HEAD silently switches to one of their feature branches without an explicit checkout — I caught it three times and each time it cost a recovery cycle (git switch main + re-merge + re-push). Agent T flagged it explicitly in its merge report; the feedback memory now codifies the defensive pattern (cd <main worktree> + git branch --show-current before every git op). Worth root-causing if it keeps biting future sessions; suspicion is the harness or post-commit hook touching shared .git/HEAD when an agent's worktree is created or destroyed. Until then, the discipline is enough.

The other recurring friction was the post-commit auto-push hook NOT firing on merge commits — it pushes plain commits cleanly but merges need a manual git push origin main. Worth investigating the hook script when convenient.

What's most valuable from this session is probably the meta-pattern of "/plan interview + 9 decisions table + reference brief" for non-trivial work. Both preview-search and idle-session-reflection went through it. The output is a plan file that next-session can /build from with no further interview — every design call already made. The investment is ~10 minutes per interview; the payoff is that the build agent doesn't have to self-decide on UX or architecture under pressure mid-build (which is when prior agents have produced wrong-direction work that had to be rolled back).

The Notion CONV import was useful but anticlimactic — 34/35 already covered by the P8 backfill that landed earlier today. The 1 new file (CONV-8, a same-day duplicate of CONV-9) is real but boring. The CONV-INDEX.md is the actual deliverable: a cross-reference table so any future reader can find any session's Notion URL + local file in O(1). Sergei can pull this on his next session.

Forge onboarding is the proof point for the canonical-store architecture. Second Mac, fresh user, single brew install --cask obsidian + git pull + one GUI toggle, and the same Obsidian vault + same canonical store + same Obsidian CLI is live. Zero per-machine drift. The deploy preview at preview.offplan.online runs from the same source. The Cloudflare Worker (when deployed) will mirror to Notion from the same source. The graph is consistent.

Learnings

Parallel subagents need disjoint file zones. Multiple agents writing to the same path → race conditions, lost commits via auto-rebase, branch-drift. Pre-plan file scopes when dispatching; tell each agent explicitly "DO NOT touch X / Y / Z, those are other agents' files." When I followed this rule, conflicts were limited to the workstream Session Log entry (which resolves with "take both"). When I didn't, agents stepped on each other.
The Stop hook + idle cron pattern from the idle-reflection plan generalises. "Cheap heuristic detection per-turn, expensive LLM analysis at low frequency" is a useful template for any always-on observation work. Could apply to other surfaces (e.g. doc-staleness detection, test-coverage drift, dependency-update awareness).
Roman's "trust the loop, no review queue" preference is consistent across surfaces. Same theme appeared earlier today in the canonical-store flip (/handoff writes directly, no review). Worth defaulting to direct-write designs for automation moving forward; review queues should require explicit justification.
Cloudflare Pages clean-URL serving strips trailing slashes from parent directories. Affects relative ../ href resolution. Not in CF Pages docs prominently; would have saved hours on the link-stacking bug to know upfront. Now captured in ADR 0020's consequences section + commit message of c6db5e0.
Plan-gated workstream creation (CONV-6780) catches over-eager agents. When the P11f /plan-first directive landed mid-wave, my Agent G (already half-built P11f) was caught and could be stopped before its work landed. Agent G's prototype was preserved via git stash as reference material. Saved a future rollback.

Open Questions

[OPEN] Worker deploy timing. workers/notion-sync/ is built, tsc-clean, wrangler --dry-run builds; scripts/deploy-worker.sh is a 9-step preflight runbook. Needs 3 secrets (NOTION_OFFPLAN_TOKEN, GITHUB_TOKEN, SYNC_AUTH_TOKEN) + 2 R2 buckets + 1 KV namespace from the Cloudflare dashboard. ~30 min of clicking + paste-IDs-into-wrangler.jsonc + bash scripts/deploy-worker.sh --apply. Should ship this week.
[OPEN] Cmd-Q + relaunch Claude Code to activate notion-offplan MCP. The .env token is replaced but the running MCP server still has the placeholder. Low priority — OAuth notion MCP is parallel.
[OPEN] PF1 (Cloudflare email obfuscation). Affects repo-as-canonical-store.html and probably others. Quick fix: toggle off "Email Address Obfuscation" in the CF Pages zone settings. Or scrub source emails. ~5 min.
[OPEN] PF2 (empty <meta name="summary"> on repo-as-canonical-store.html). Plan's frontmatter success_criteria is long; summary: field is probably missing. Author one. ~2 min.
[OPEN] PF3 (empty "How it evolved" on CONV-10). Design call: hide the section vs graceful empty state. Needs /plan-first per the workstream brief.
[OPEN] Idle-reflection /build. Plan ratified at 2a3261a. 8 phases (R1–R8). Stop-event hook (R1) is the cheapest to ship first; reflection daemon (R2 + R3) is the heavier piece. 2–3 sessions estimated.
[OPEN] preview-search /build. Plan ratified at 5282953. Already shipped via Agent K — but the post-/plan check on Group D items (operator state cues) hasn't been validated against any real sessions yet. Will see after 1 week of dogfood.
[OPEN] Frontmatter schema widening for duration_min: null. 2 sessions fail validation because the schema requires integer. Should be [integer, null]. Trivial fix, deferred to keep the wave 4 scope tight.
[OPEN] Worktree branch-drift root cause. Defensive pattern works but the underlying bug is unsolved. Investigate when convenient.
[OPEN] Post-commit hook not firing on merge commits. Same. Investigate.

Resume Prompt

Vault workstream is DONE — all 9 phases shipped 2026-05-11 plus a Notion-zero hard-gate, a Cloudflare Worker port (built/undeployed), the Forge Mac mini onboarded with Obsidian 1.12.7 CLI, 5 new ADRs (0018–0022), 60 new tests (231 passing), Notion OAuth wired + CONV-INDEX.md mapping all 35 sessions, and the link-stacking bug fixed across 115 about-pages. Plans ratified for preview-search (already built; 5282953) and idle-session-reflection (2a3261a — 9 decisions ratified; not yet built). Most impactful next moves: (1) Idle-reflection R1 /build — Stop-event memory-queue hook is cheapest single-phase ship and immediately useful; (2) Worker deploy — bash scripts/deploy-worker.sh --apply after pasting 3 secrets + R2/KV IDs into wrangler.jsonc (~30 min); (3) PF1+PF2 polish — toggle CF email obfuscation off + author the empty meta summary (10 min combined). Watch out for: (a) the worktree-branch-drift bug — see feedback_worktree_branch_drift.md, cd <main worktree> + git branch --show-current before every git op; (b) .env NOTION_OFFPLAN_TOKEN is replaced but MCP server still running with placeholder — Cmd-Q + relaunch Claude Code to activate notion-offplan; (c) PF3 design call (empty "How it evolved" section) needs /plan-first. Confidence: H.
