docs: correct stale cron schedule (Sun → Mon-Fri, 4 files) + subagent count 15→18 + INFLIGHT.md housekeeping

[dackclup]

Summary

User-triggered correction: "ฉันจะ manual ส่วนคุณแก้ใขไม่ให้ผิดพลาดอีก ทั้งเรื่องนี้และเรื่องอื่นๆ เช็คและอัพเดทข้อมูลให้เป็นปัจจุบันทั้งหมด"

I repeatedly stated "cron Sun 22:00 UTC (~7h)" / "(~14h)" / "(~19h)" in session 7 PR summaries despite the actual .github/workflows/compute-rankings.yml schedule being "0 22 * * 1-5" (Mon-Fri only). The workflow's inline comment even says "Weekends skipped (no new trading data)". The handoff prompt at session start said "Next prod cron: Sun 2026-05-24 22:00 UTC (cron-#4)" and I echoed without verifying against the YAML — git log --all -p confirms the schedule has been "0 22 * * 1-5" since the workflow was created. The handoff itself was wrong.

Cron-schedule corrections (4 files)

File:Line	Before	After
CLAUDE.md:31 (§Stack)	"weekly compute-rankings.yml (cron Sun 22:00 UTC)"	"weekday compute-rankings.yml (cron Mon-Fri 22:00 UTC; weekends skipped — no new trading data)"
docs/RESEARCH_FINDINGS.md:854	"WEEKLY (GitHub Actions, Sunday 22:00 UTC)"	"WEEKDAY (GitHub Actions, Mon-Fri 22:00 UTC; weekends skipped)"
docs/ARCHITECTURE.md:7 (mermaid)	"GitHub Actions cron / Sun 22:00 UTC" + "run weekly"	"GitHub Actions cron / Mon-Fri 22:00 UTC" + "run weekdays"
docs/stock_ranking_knowledge.md:993	"Weekly Sunday 22:00 UTC: Main compute cron"	"Weekday Mon-Fri 22:00 UTC: Main compute cron (weekends skipped — no new trading data)"

Companion stale-info found during audit

• AGENTS.md:1294 — "The 15 subagents under .claude/agents/" → "The 18 subagents under .claude/agents/". Post-PR feat(agents): add ci-triage-engineer + vercel-preview-auditor + literature-searcher (15 → 18) #225 the roster expanded to 18 (ci-triage-engineer + vercel-preview-auditor + literature-searcher). AGENTS.md:91 already said 18; line 1294 was unsynced drift.

PHASE_STATUS_INFLIGHT.md housekeeping

Per PR #237 convention (append-only with periodic move from "In flight" → "Merged" sub-section):

• PR ci(simulate) Part 5: wire QR_SKIP_OSAP + add compute/cache/osap to cache paths (closes 4th external-data loop) #241 (simulate Parts 5+6+7, e9d7836) — moved to Merged with consolidated 4-iteration summary preserving the QR_SKIP_OSAP + QR_SKIP_CROSS_SOURCE + timeout-45→90 history
• PR feat(frontend): light-mode soften + Strong Buy nowrap + StockLogo square #242 (light-mode soften + Strong Buy nowrap + StockLogo square, a30c017) — moved to Merged, original entry text intact
• Duplicate ## Merged header at the prior line 257 deleted (rebase-artifact from PR docs: triple-doc lockstep refresh (PHASE_STATUS + SKILL + WORKFLOW) — unblock v1.3.0 release tag #239 + PR docs(workflow): housekeep PHASE_STATUS_INFLIGHT.md — move PR #238 entry to Merged section #240 chronology resolution); file now has exactly ONE Merged section
• Old "PR (this PR) — Simulate Parts 5+6+7" body block excised (~100 lines) — replaced by this PR's Doc-staleness sweep entry in the In-flight section

Audit completeness (verified current, no fix needed)

• Schema version 0.10.2-phase4.5e — verified current across CLAUDE.md, PHASE_STATUS.md, AGENTS.md
• Defense layer "32 boolean flags emitted" — verified current
• Subagent file count = 19 in .claude/agents/ (18 agent files + 1 README.md) — corresponds to 18 subagents, AGENTS.md:91 + :1294 now both consistent

No compute / schema / scoring / valuation / Python / TypeScript code change. Doc-only PR.

Test plan

• git log --all -p .github/workflows/compute-rankings.yml | grep cron: confirms schedule has only ever been "0 22 * * 1-5"
• grep -rn "Sun 22:00\|Sunday 22:00" confirms 0 remaining stale refs across project
• grep -nE "## (PR|In flight|Merged)" PHASE_STATUS_INFLIGHT.md confirms 1 In-flight + 1 Merged section
• Frontend (build) CI green (doc-only)
• Python (lint + test) CI green (doc-only)
• Vercel preview deploys green

Note about the recurring "Sun" mistake

The handoff prompt error + my echo-without-verify propagated across 5+ session summaries in PRs #226 / #237 / #240 / #241. None of those PRs' shipped doc content has the wrong cron schedule (those PRs touched different files); the error was in my chat summaries only. Going forward I'll verify time-sensitive claims against source-of-truth files (YAML / config / git log) before stating them.
