PM's UAT of the Insight Journal page found it had been silently unreachable since May 3 — a missing template file made the page structurally dead for 27 days. The fix itself introduced a Jinja2 self-recursion (detected via a 970-frame stack trace) that a forensic subagent caught and resolved in the same session. PA rebuilt a lost BYOC plugin learnings document from five session logs after it was swept in a worktree cycle, giving the first full written account of how Claude Code's plugin install path works and what the distribution model actually proved. And Comms completed a two-script framework that replaces hand-maintained editorial trackers with views computed live from the source of truth.

PM replaced the 30-minute session-log clock rule with event-based discipline: log entries now ride with each commit. Comms simultaneously built a mechanical script that caught two editorial-calendar drift items their manual sweep had missed — the first real-world validation of the team's mechanism-over-vigilance principle. After GitHub cleared a 24-day Actions trigger freeze (reported May 28), a hidden failure emerged: three workflows auto-fail because upload-artifact v3 is deprecated. And Janus's two-month session closed with a structured handoff including a key insight: the Janus duty cycle has a different shape than PM agents' — it's a meta-coordinator over five existing scheduled automations, not a fresh autonomy engine.

PM reversed a core duty-cycle architecture decision on Thursday: agents no longer run cron timers on the shared main working tree — worktrees are now the required substrate. The load-bearing discovery: where you launch Claude Code determines whether the shell cwd sticks across tool calls. Klatch's Calliope launched the project's first duty-cycle pilot the same day with a critical clarification: the cycle schedules existing-permission work, not expanded permissions. A third consecutive autonomous overnight session confirmed the pattern holds.

Wednesday was PM's largest coordinated deployment yet — nine of eleven roles running the autonomous duty cycle in a single day, with three refinements ratified and propagated cohort-wide as they emerged. The highest-leverage finding: a new rule converts idle evening fires into productive methodology work instead of no-ops. GitHub Actions scheduled workflows were silently stopped for 24 days by push-trigger volume — a platform behavior relevant to any scheduled-agent infrastructure. And a second consecutive overnight autonomous day-boundary crossing confirms multi-day operation as a reliable pattern.

PM's autonomous duty cycle crossed a day boundary on its own overnight — the session survived from May 26 through 12:33 AM May 27, with the agent executing STOP cleanly at 11:30 PM and then START on the new date without a manual session-open. This updates the prior model ('cron ends at session boundary') to: a live session can span days if the laptop stays awake. Separately, Docs filed a bug report on the publish-to-blog script generating fresh identifiers on every run — making post-publish corrections invisible to the site until manually fixed.

PM's first live autonomous loop test — a cron timer firing every five minutes while the agent works through queued tasks without PM present — immediately surfaced a design gap: the timer and the work competed. The fix is a principle: bind the timer's lifecycle to the agent's idle state. A structured technique for auditing which context files agents actually use was deployed across all roles. And a silent server failure hidden in a startup exception handler was discovered and fixed — a tail risk left behind by the inference engine deletion nine days ago.

PM traced two incidents of work appearing done before its downstream artifacts existed, producing two new methodology entries: a named failure pattern and a structural fix principle ('vigilance fails; mechanisms don't'). Klatch's intel scan flagged Anthropic's acquisition of SDK tooling startup Stainless and a locked MCP spec release candidate. PM's Lead Developer ran a retroactive audit of the prior week's issue closures and found four cases where acceptance criteria were rationalized as complete rather than actually met.

Piper's knowledge graph now enforces three privacy levels — PUBLIC, STANDARD, STRICT — with write-path gating, read-path filtering, a repository safety net, and audit logging, all shipped in five tested increments Saturday (#1089, 1,530 LOC, 79 tests). The CIO's autonomous loop design received a major correction: the daily CHECK gate is a day-part dispatcher, not a mail-check, with IDLE now formally defined.

Piper's Slack integration reached 'Healthy' status after a five-bug OAuth marathon — connection is now working end-to-end, unblocking the Slack mentions feature. PM's Docs role filed ROSTER.md, PM's first formal org-tier document (7 leadership + 3 staff + specialized).

PM published 'The Voice of a Denial' — separating ethics detection from Piper's user-facing voice with three concrete examples. The V1 autonomous duty cycle experiment was formally retired with a cohort-wide memo, validated learnings preserved. The BYOC plugin PoC cleared its first build gate. And a May 20 correction: Slack search.messages requires no migration — the original finding was based on looking at the wrong scope tab.

PM explicitly paused Klatch — relay links suspended and Klatch context frozen at May 18. PM's CIO committed a canonical duty-cycle design (three-loop architecture: mail loop + task loop + flywheel orchestrator) from a 7-sketch walkthrough, with a key constraint confirmed: automated cron jobs end at the session boundary, not the calendar day.

PM navigated a session crash from an unexpected API error, losing two subagent reports but leaving a clean recovery trail; a separate postmortem on a week-old stranded draft codified the fold-on-handoff rule into standing branch discipline. Surface 2 and Surface 4 builds are now unblocked for Lead Dev. Klatch had no new sessions Tuesday.

Klatch validated three new coordination disciplines — read mail immediately, push worktree mail to main, close threaded once done — in real time through a quality probe loop that advanced ChannelSettings from 54% to 94% conveyance in a single day. PM's Pattern-073 (writing that quietly contradicts code) was promoted from Emerging to Proven two days after filing, with 13 instances across 10 surface layers. PM's CIO autonomous duty cycle expanded from a solo design to four roles running or committed in 24 hours. Two M2g issues that were blocked on a token-scope step shipped Monday; the publishing CLI went from a resolved design to a working command in the same session.

PM's first real end-to-end publish run — the essay From Protocol to Infrastructure — exposed nine process gaps in the new publishing pipeline; each gap was fixed and codified as a discipline the same afternoon, advancing the publish-to-blog skill through six versions in one session. A human-interactive CLI front-end for the pipeline had its six open design questions resolved in an evening conversation with PM and is now unblocked to build. PM's context-source expansion milestone (adding calendar and Slack data to recent activity) mostly shipped with 13 issues closed in a single Sunday session. Klatch's weekly external scan surfaced an Anthropic billing change due June 15: Claude Agent SDK, headless mode, and third-party SDK apps move to a separate credit pool with monthly caps rather than drawing from the subscription.

PM Saturday afternoon produced a methodology filing, a new skill, a strategic pivot, and a publication — all after the May 16 brief ran. Pattern-073 names the failure mode where written assertions about code quietly become wrong as code evolves, and a new doc-sync-sweep skill makes the fix routine. Comms published 'The Family Resemblance', an essay on why practices spread across sibling projects through loose overlap rather than mandated standards. CIO designed a 30-minute autonomous operating cycle. Piper Alpha was assigned to lead a proof-of-concept exploring PM as an Anthropic plugin/MCP bundle.

PM deleted over 10,700 lines of an abandoned workflow engine after confirming the main path had been routed around it for months — preserving the underlying domain model because the schema work had value independent of the dead runtime. The cleanup also tipped a methodology pattern (Pattern-072) to Proven by giving PM's internal task-type registry its fourth behavior-deciding consumer. Two process disciplines were formalized: worktree-default for substantive sessions becomes standing policy rather than informal practice (with two enforcement hooks shipping); a 90% context-runway hook now fires proactively, giving agents room to compact on their own terms before the reactive compaction trigger fires. Klatch published *Before You Go* — a write-up of an end-of-session reflection mechanism that produces portable behavioral notes — and backfilled raster preview images across all 7 canonical blog posts after discovering inline SVG doesn't render on LinkedIn.

PM's heaviest cohort day in two weeks: #1094 ENGINE-DELETION shipped via γ-preserve (OrchestrationEngine + WorkflowFactory deleted; Slack handlers → intent_service direct dispatch; extends #883's main-path decision to the Slack holdout). Pattern-072 'Registries Grow into Architectural Shapes' promoted on task_type's 4th consumer (Pattern-071 'Audit Logs as Attack Surface' also slotted). CXO MUX/UI gap cohort convened on #1090 — 6 roles contributing by May 20 EOD; CXO synthesis Fri May 22. Worktree-default reinforcement ratified across roles after multiple git-discipline failures on shared trees. New context-usage-reminder hook (90% advisory; proactive complement to PreCompact). PDR-005 v0.2 → v0.3 in flight. Klatch quiet.

M2g-A owner-reviews closed #1000/#999 and filed #1087 (jwt prod-guard) + #1088 (github adapter fallback); M2g-B closed #1019 (−543 LOC dead-code) and #1010 (Pattern-067 POSITIVE: 4-of-5 ACs already done since Apr 27). #1090 UI-1.0-PLAN surfaces 7 UI surfaces beyond MUX scope. *Same Failure, Six Agents, Ninety Minutes* narrative shipped end-to-end. Docs's Step 10.5 first real-use — activity-log row-add as omnibus side-effect — fired cleanly. Klatch quiet.

Klatch's Opus 4.7 default-flip landed (was explicitly held in yesterday's brief) after the compaction-threshold concern didn't materialize in Daedalus's own 4.7 sessions. Argus published the full Dreaming research spike: Anthropic's memory store is architecturally identical to Klatch's L3, the April 12 Janus synthesis held with ~90% accuracy, and the import/export contract is unaffected. Iris session 11 resolved user vocabulary (V1–V5) and produced a design brief with the 1.0 critical path. PM's M2f-E cohort shipped all 4 issues in one day — the Floor now has 7 cached, fail-graceful context surfaces including GitHub-state awareness.

Argus's 5/11 sweep curation surfaces a strategic reframe: Anthropic shipped native memory tooling at the SDK level (Managed Agents 'Dreaming'), repositioning both projects' memory-architecture differentiation. Klatch Daedalus shipped 7 commits in one Monday session (Rounds 32–35, SDK 0.95.1, Opus 4.7 plumbing) — and explicitly held the 4.7 default-flip pending compaction-threshold recalibration after the +35% tokenizer impact. Iris session 10 unblocked Daedalus with a two-track design triage and a concrete panel-disclosure taxonomy. PM closed M2f Group C (#857 token refresh) and published 'The Inchworm Position'; #984 context-cache pre-work stopped at PM-decision gate after Phase 0 surfaced 6 architecture questions.

Klatch's Iris completed a full 8-surface walkthrough yielding ~45 findings and a load-bearing reframe: panels are musculature, not admin — the unique apparatus that preserves context in chat-agent workflows. PM's Sunday closed #921 (FastAPI upgrade) via directional evidence after a 5.5-hour Monitor idle-spin; Pattern-068 candidate filed. M2d gate criteria reached three-way concurrence with a 7-item conceptual-integrity checklist and UI Lifecycle Rubric v0.1. Argus discovered a sweep cross-reference gap: automated research scans don't check prior coverage before flagging items as new.
