- platform.sh: nh_ensure_instance/nh_entry_write now use per-SITE instance
  (port 9300+hash(site), profiles/<site>/) so one account logs in once per
  site; prevents same-account multi-login session kicking (digitimes/nikkei
  both enforce device limits)
- harvest.sh: quit shared instance on EXIT with port-keyed reference counting
  ($WORK_DIR/runlocks, stale-PID cleanup) — last same-site run recycles
- harvest.sh: hard watchdog kills a hung claude run after MAX_RUNTIME_MIN
  (default 60, per-source conf overridable) so launchd next-day trigger is
  never blocked

- index: unscheduled sources no longer link to /source (was 404); show 未排程 badge
- index: sources with toggle ON sort first
- logins page: split into per-source login-state table (site-shared instance
  column, per-source test via new /login-test-src route) + site-credential table
- platform_layer: skill_sources() exposes method; login_sites() drops direct
  sources; new login_source_rows()

- platform.sh nh_login_autodiscover: no installed source for the site
  (bloomberg/statista) exports NH_LOGIN_URL from the credential's url
- web: site rows without sources can run 自动配置配方/登录测试 (probe
  falls back to site name); credential url serves as discovery entry

- platform.sh: credential lookup falls back site-level (logins/<site>.json,
  site = first segment of source name); nikkei-world/markets/tech share one
  nikkei account, single file to maintain
- platform_layer: login_sites()/login_rows() site view (coverage, probe
  source, recipe status) for the panel
- web: /logins page now site-based — save/delete/discover/test operate per
  site; discovery probes via the site's representative source

nh_login_preflight assumed the per-source Chromium was already running
(panel login-test failed silently for sources whose window had been
closed); extract nh_ensure_instance (no-op when alive) and use it in
both preflight and autodiscover. Harvests were unaffected — harvest.js
already runs ensure-chromium itself.

- nh_login_autodiscover (platform.sh): ensure the source's dedicated
  browser instance is up, load credentials, run skill discover
  (recipe generation + live login verification)
- /login-discover route + 自动配置配方并测试 button for sources with
  credentials but no recipe; reuses the background-test polling UI

- sudo -u yichu replaced by NH_RUN_USER env (linux panels running as
  root configure the execution user; empty = current user, darwin
  always direct) — last hardcode outside guarded legacy tools
- logins.html: emit meta refresh only while a login test is running
  (content=0 caused an infinite reload loop)
- deploy/migrate keep their overridable yichu defaults (legacy server
  tools, already parameterized via args/env)

- /logins page: per-source credentials CRUD (write-only password,
  masked display, 600-perm files in etc/news-harvester/logins/),
  recipe availability badge, one-click login test (background thread,
  page polls result)
- nh_login_preflight auto-selects the source's dedicated browser
  instance (port+profile) when caller didn't set one
- panel env carries SKILLS_DIR so recipe detection works in-process

- nh_login_preflight (platform.sh): sources with credentials at
  $CONF_DIR/logins/<source>.json (600) get a login check via the
  skill's login-tools.js before claude runs; auto-login on failure;
  harvest never blocked (paywall honestly reported by result contract)
- harvest.sh invokes preflight after result contract preparation
- SKILLS_DIR / SKILLS_REPO_URL documented in default.conf.example
- test: preflight invoked when credentials configured (fake skill)

- nh_cdp_port: stable per-source CDP port (9300+name hash)
- nh_entry_write: entry scripts now export CDP_PORT_OVERRIDE +
  CDP_PROFILE_OVERRIDE so parallel harvests each drive a dedicated
  Chromium (own port + own profile); regenerated idempotently
- pairs with news-hub-skills CDP_PROFILE_OVERRIDE support
- darwin test asserts isolation env in generated entry

- bin/setup.sh: one-command machine bootstrap (auto platform detect) —
  directory layout, dependency check (brew install on consent), claude
  auth check, skills repo auto-clone from SKILLS_REPO_URL + npm install
  + full bundle import (all sources), dual skill symlink registration,
  default.conf/web.conf generation (random panel password), optional
  web panel service install, digest schedule, remaining-manual-steps
  summary; idempotent
- web/app.py: platform_layer integration — paths/timer reads/trigger/
  active-harvest checks unified; add/edit/disable actions now work on
  darwin; per-source harvest toggle route (schedule load/unload +
  skill enable/disable; auto staggered schedule creation on first enable)
- index.html: toggle switch column, unscheduled skill sources merged
  into list, platform-neutral labels
- bin/platform_layer.py: python facade reusing platform.sh via
  'platform.sh call' dispatcher for all mutations; file reads native

- bin/platform.sh: single source of truth for platform differences —
  OS detection (NH_OS override for tests), PATH bootstrap without
  shadowing caller-injected commands, platform default paths, scheduler
  abstraction (systemd timer + systemctl <-> launchd plist + launchctl
  with named entry scripts), file-level disable on darwin (survives
  reboot, one-click recoverable), sed -i / GNU-sed shims, root check
  only on linux, conf loading (EnvironmentFile equivalent)
- bin/schedule.py: plist parse/write + auto-detect by filename
  (timer/plist/.disabled); schedule sources listing subcommand
- harvest/continue/daily-digest: drop hardcoded nvm//home/yichu paths,
  self-bootstrap via platform.sh, harvest now loads conf itself
  (run.sh wrapper no longer required)
- add-source/modify-source: fully cross-platform schedule management
  (plist generation + launchctl on darwin, timer + systemctl on linux)
- status.sh: cross-platform overview/detail/journal (launchd log on darwin)
- deploy/migrate: linux-only guard with pointer to setup.sh
- tests: env-synced platform simulation (NH_OS), fake launchctl suite,
  darwin plist/disable/enable roundtrip tests; new disable contract
  (unload + preserve times) replaces clear-times; 37 tests green

- web/app.py: IS_DARWIN branches (launchctl kickstart for manual trigger,
  direct execution for digest/continue without sudo); _active_harvests()
  concurrency guard on /run and /continue; normalized detail state
  (last run time from log filename, next trigger computed from schedule)
- detail.html: layout redesign — status badge header, real overview cards,
  merged duplicate run metadata, collapsible logs/config, history moved up
- gitignore: exclude .zcode/
