# assistant — start, status, patrol, stop
The background assistant runs where nobody is watching it. Its heartbeat is the only evidence that it is alive, so this skill is the single entry point for the four operations that touch that evidence: `patrol` writes it, `status` reads it, `stop` clears it, and `start` bootstraps the whole loop.
`$JSC_HOME/current/jsc-hooks/hooks/heartbeat.sh` owns every heartbeat operation, including the freshness verdict. Never read, parse, write or delete `$JSC_HOME/assistant/heartbeat` directly — one verdict, one source.
`{CURRENT}/jsc-hooks/hooks/heartbeat.sh` owns every heartbeat operation, including the freshness verdict. Never read, parse, write or delete `$JSC_HOME/assistant/heartbeat` directly — one verdict, one source.
`$JSC_HOME/current/jsc-assist/tools/schedule.sh` owns every system-scheduler operation: installing an entry, removing it, and reading which entries exist. Never call `crontab` or `schtasks` from this skill, and never edit a crontab by hand.
`{CURRENT}/jsc-assist/tools/schedule.sh` owns every system-scheduler operation: installing an entry, removing it, and reading which entries exist. Never call `crontab` or `schtasks` from this skill, and never edit a crontab by hand.
`$JSC_HOME/current/jsc-assist/tools/patrol.sh` owns one patrol round: taking the round lock, reading the four sources, composing the monitor page's blocks, and — after the page carries this round — writing the heartbeat. Never re-read a source this skill already handed to that script, and never compose a block by hand; the script prints the file paths.
`{CURRENT}/jsc-assist/tools/patrol.sh` owns one patrol round: taking the round lock, reading the five sources, composing the monitor page's blocks, and — after the page carries this round — writing the heartbeat. Never re-read a source this skill already handed to that script, and never compose a block by hand; the script prints the file paths.
All three flows have fixed inputs and outputs, so all three live in scripts. The task book is the only thing this skill reads for itself, and that is one directory listing.
## Step 0 — take the tool root from the invocation
Every operation starts here, before its own step 1. **This document calls the tool root `{CURRENT}`**, and every `{CURRENT}` below is replaced by it character for character: `{CURRENT}/jsc-assist/tools/patrol.sh` is run as `/root/.jsc/current/jsc-assist/tools/patrol.sh`.
The root comes from outside this skill. `schedule.sh` resolves it while a person is installing the schedule, and writes it into the entry's prompt as `工具根目錄={literal absolute path}`, so the round that entry wakes reads the root out of the text that woke it and runs no command at all.
| Who invoked this round | Where `{CURRENT}` comes from |
| --- | --- |
| the schedule — an unattended round, the `patrol` whose trigger is 排程 | the path after `工具根目錄=` in the invocation text, taken verbatim. No command is run |
| a person, in front of the terminal | the same token when the invocation carries one; otherwise `readlink -f "$JSC_HOME/current"`, run once |
**An unattended round that finds no root in its invocation stops there.** Report that the scheduled entry carries no `工具根目錄=` — an entry written by an older `schedule.sh` — say the fix is to run `start` again, or `jsc-assist/tools/schedule.sh install patrol` under `$JSC_HOME/current`, so the entry is rewritten with the root in it. Then take the operation's `aborted` status, write the `skill-end`, and stop.
Never work the root out instead. `readlink -f "$JSC_HOME/current"`, `ls -d "$JSC_HOME/current"` and every other resolve are refused in an unattended session — measured, see the table below — so running one does not produce a root, it produces a round that stops one step earlier having recorded nothing. Never fall back to `$JSC_HOME/current` as a written-out path either, never take a path from the plugin prompt or a previous transcript, and never guess.
**Only an attended invocation may resolve the root itself.**`readlink -f "$JSC_HOME/current"` covers the documented `~/.jsc` fallback in the same call and prints one literal absolute path. It raises one permission prompt, and a person is there to answer it once. That is the whole reason the branch exists: portability survives where somebody can approve it, and nowhere else.
Take the root once per invocation and reuse that one answer. Never resolve it again per call, never print it as a report line of its own, and never add a tool that prints it. Never test the root with a command either — an unattended round cannot, and the first script call is the test that matters anyway.
An empty token, an empty `readlink` result, a path that is not absolute, or a resolved path that is not an existing directory means there is no root to work with. **That fourth item is the one the other three wave through.** With `JSC_HOME` unset, `readlink -f "$JSC_HOME/current"` prints `/current` and exits 0 — non-empty, absolute, and past every other item — and each literal path built from it then names a place that is not there. So the attended resolve is only accepted once `[ -d "{the path just printed}" ]` says that directory exists, run in the same approved step as the resolve itself. The unattended round tests nothing, exactly as above: its root was written into the entry by whoever installed the schedule, and its first script call is what fails if that root is wrong. Report it, say `jsc-cli:deploy` has to run, take the operation's `aborted` status, and stop. Never fall back to a cache path, and never create the root here. Completion condition: one literal absolute path is in hand and every later command line carries it, or the missing root was reported and the operation stopped.
## Every script call carries a literal absolute path
**No command line in this skill carries a variable or a tilde, and the one resolve above is the single exception, allowed only when a person is watching.** Never type `$JSC_HOME`, `${JSC_HOME}` or `~` into any other command line.
The reason is the permission layer: it matches its rules against the command text as written, before the shell expands anything. Two properties follow from what was measured on this machine, and every rule in this skill rests on them:
1.**Unattended, only a full literal command that is on the allow list runs.** There is no such thing as a read-only command that is safe by default: a bare `ls -d` is refused exactly like everything else, and a refusal in a session with nobody in it is silent.
2.**A wildcard in the middle of a path does not match.** The rule and the command both have to be complete literals. A rule holding `*` where a version number goes matches nothing, so a cache path is refused however the rule is written.
| Command | Result |
| --- | --- |
| `/root/.jsc/current/jsc-assist/tools/patrol.sh` — a literal rule for it is on the allow list | ran |
| `ls -d /root/.jsc/current` — literal, read-only, no rule for it | refused |
| `/root/.claude/plugins/cache/jsc/jsc-assist/0.1.0/tools/patrol.sh` — rule written with `*` for the version segment | refused |
A literal allow rule that itself starts with `$JSC_HOME` was added to the settings file and the same call was still refused, so no permission rule makes the variable form work either. The literal path is the whole fix, on both sides.
**These rules outrank portability, and the next maintainer is the one who has to know why.** A variable in the path reads as the portable choice and costs nothing while a person is watching: the prompt appears, somebody approves it, the round carries on. The scheduled round has nobody to approve it. It stops at its first script call, records nothing, writes no heartbeat, and the machine then reads as a stopped assistant with no trace of the refusal anywhere. And the resolve is no way out of that, because row 4 of the table is the resolve itself: a round that cannot run a script cannot run the command that would have told it which script to run. That is why the root is handed in by whoever installed the schedule, and why anything written into a command line here is already literal.
## Tool paths
Every tool below is addressed through `$JSC_HOME/current/{plugin}`, and `$JSC_HOME` falls back to `~/.jsc` exactly as everywhere else in this skill:
Every tool below is addressed through `{CURRENT}/{plugin}`, with `{CURRENT}` standing for the literal path step 0 took:
| What it does | Path to run |
| --- | --- |
| one patrol round | `$JSC_HOME/current/jsc-assist/tools/patrol.sh` |
| the system scheduler | `$JSC_HOME/current/jsc-assist/tools/schedule.sh` |
| the heartbeat | `$JSC_HOME/current/jsc-hooks/hooks/heartbeat.sh` |
| the wiki, through `jsc-gitea:wiki` | `$JSC_HOME/current/jsc-gitea/tools/gitea.sh` |
| the `MONITOR_CONTENTS` row | `$JSC_HOME/current/jsc-gitea/tools/wiki-contents.sh` |
| one patrol round | `{CURRENT}/jsc-assist/tools/patrol.sh` |
| the system scheduler | `{CURRENT}/jsc-assist/tools/schedule.sh` |
| the heartbeat | `{CURRENT}/jsc-hooks/hooks/heartbeat.sh` |
| the status event stream | `{CURRENT}/jsc-hooks/tools/report-status.sh` |
| the wiki, through `jsc-gitea:wiki` | `{CURRENT}/jsc-gitea/tools/gitea.sh` |
| the `MONITOR_CONTENTS` entry | `{CURRENT}/jsc-gitea/tools/wiki-contents.sh` |
| the link check every write depends on | `{CURRENT}/jsc-gitea/tools/link-check.sh` |
**A `Skill(...)` rule permits invoking that skill and nothing more.** Every Bash call inside it is still checked on its own, so `jsc-gitea:wiki` reaching the wiki depends on `gitea.sh` carrying its own rule, and the directory row depends on `wiki-contents.sh` carrying one too — without them the round is refused locally, before any request leaves the machine, and the page never gets written.

**Never build a tool path out of the base directory the CLI hands you in the skill prompt.** That directory points into the plugin cache and carries a version segment, and the permission gate allows exactly the five paths above and nothing else. A cache path is therefore refused silently: the round stops on a permission prompt nobody can answer, records nothing, writes no heartbeat, and the refusal looks exactly like a broken tool. Read the paths off this table every time — not off the prompt, not off a previous transcript, not off `crontab -l`.

A cache path is therefore refused silently: the round stops on a permission prompt nobody can answer, records nothing, writes no heartbeat, and the refusal looks exactly like a broken tool. Read the paths off this table every time — not off the prompt, not off a previous transcript, not off `crontab -l`.
Both scripts check this for themselves: run from anywhere outside `$JSC_HOME/current`, they print a `[WARN]` line on stderr naming the path they were started from and the path they should have been started from, and then carry on. That line means this round is on the wrong path — quote it, fix the path, and do not treat the round's success as proof that the path was fine.

That line means this round is on the wrong path — quote it, fix the path, and do not treat the round's success as proof that the path was fine.
`current` is a set of version-free links that `jsc-cli:deploy` maintains, so an upgrade moves the cache and leaves these paths alone. When one of them is missing, report the missing link and say `jsc-cli:deploy` has to run; never fall back to a cache path to get the round through, and never create the link here.
## Two rules bind every link this skill writes
Both pages this round writes carry links, and both rules below hold for every one of them — the monitor page and the directory entry alike.
**Rule A — a link is always written as `[{text}]({URL})`.** The wiki's own `[[page]]` and `[[text|page]]` forms are not used here at all, and neither is the split between "same repo" and "cross repo" writing. The URL comes from `{CURRENT}/jsc-gitea/tools/gitea.sh wiki-url {repo} {page}`; never assemble a path by hand. `[[...]]` resolves only inside the wiki it sits in: the monitor page and the directory page live in two different repos, so a `[[MONITOR_{HASH}]]` written into the directory entry renders as an ordinary-looking link that goes nowhere, and nothing reports it.
**Rule B — a link is verified before it is written, never after.** Collect every link that is about to go into the page, hand the whole set to `{CURRENT}/jsc-gitea/tools/link-check.sh`, and write only on exit 0. The script prints one `{OK|DEAD|SKIP}<TAB>{URL}<TAB>{note}` line per URL and checks Gitea URLs through the API, never through the web status code — a private repo answers 404 to a logged-out web request, so a status-code check condemns live pages.
| Exit | Meaning | Do |
| --- | --- | --- |
| 0 | every link resolves | write the page |
| 1 | at least one link is dead | write nothing, report the `DEAD` lines verbatim, and take the step's own abort row |
| 2 | usage error — no URL was given | a defect in the call: pass the URLs and run it once more |
| 3 | a Gitea URL is in the list but `GITEA_HOST` is unset | report the variable and stop; never skip the check to get the write through |
| 7 | Gitea authentication failed (401, 403) | stop and report it as a token problem, never as dead links — an expired token makes live private pages look missing |
A round with no link to write skips the call and says so; a round that cannot verify writes nothing.
## Pick the operation
Run exactly one operation per invocation. Take it from the request: starting, launching or waking the assistant is `start`; asking whether it runs, what it is doing, or what is queued is `status`; running one round, patrolling, or a scheduled wake-up is `patrol`; stopping, halting or shutting it down is `stop`. When the request names none of the four, or names more than one, ask through the `jsc-ask:ask` decision tree with those four as the options, each stating its effect — `start` runs one round and installs the scheduled entry that keeps running rounds, `status` changes nothing, `patrol` runs one round and writes one heartbeat, `stop` removes that entry and deletes the heartbeat. **The one exception: a `patrol` invocation never asks anything at all** (see 界線 1 below). Never guess, and never run a second operation the caller did not ask for. Completion condition: exactly one of `start`, `status`, `patrol`, `stop` is chosen and named in the report.
## Every operation ends with one status event
The last thing any of the four operations does, after its report is printed, is write its own end event:
The `start` half is already on record — a hook writes it when this skill loads — so this call is what tells the difference between an operation that finished and one that stopped half way. **Skipping it makes this skill's own run look aborted**, and the next patrol round reports it as such, on the page this skill writes. Pick the status from what actually happened:
| status | When |
| --- | --- |
| `ok` | the operation reached its own completion condition |
| `blocked` | the round stood down because another round holds the lock, or `install heartbeat` was refused — nothing was done and nothing is wrong |
| `failed` | a step returned a code that stopped the operation: `collect` exit 5 or 6, a monitor-page write that could not be made, `remove` non-zero in `stop` |
| `degraded` | the operation finished with a known gap: the directory entry was left unwritten, or the schedule entry was installed but the cron service is stopped |
| `aborted` | the operation stopped because a precondition did not hold, such as an empty `hash=` or a missing `current` link |
The call never changes the outcome: it returns 0 even when it cannot write, and a non-zero from it is reported as a defect in the reporting chain, never as a failure of the operation that just succeeded. Completion condition for all four operations: exactly one `skill-end` was written, and its status matches the outcome that was reported.

- **The log lives at `$JSC_HOME/assistant/schedule.log`**, deliberately outside every repository. Do not offer to move it into a project.
- **The entry runs with no human present.** The command is installed with `</dev/null`, so nothing it runs can block on input. A patrol round that stops to ask for a tool permission hangs that round, and the lock it holds stands the next round down until the lock ages out — which is why `patrol` asks nothing, of anybody, ever.
- **The entry carries its own environment.** cron gives it a short `PATH`, no settings file and no tty, so `schedule.sh` writes three things into the entry: the CLI resolved to an absolute path with `command -v`, a snapshot of the wiki variables taken at install time (`GITEA_HOST`, `GITEA_TOKEN`, `JSC_HOME`, `JSC_ASSISTANT_HEARTBEAT_TTL` and every set `JSC_WIKI_REPO*` — `JSC_WIKI_REPO`, `JSC_WIKI_REPO_MONITOR` for the monitor page and `JSC_WIKI_REPO_CONTENTS` for the directory page, which the script picks up from the environment rather than from a hardcoded list), and `JSC_GITEA_CONFIRM=yes`, because the write confirmation only recognises a tty and an unattended round has nobody to confirm. Two consequences belong in every report: the entry holds a copy of the token, so the crontab file has to stay readable by its owner alone, and a changed variable only reaches the entry after another `install`. `install` prints the snapshotted names in `env_snapshot=` and masks the token in every entry it prints — never print an entry read from `crontab -l` yourself.

Hand them to the operator verbatim: an unattended round that hits a permission prompt hangs until the lock ages out, and nobody is there to approve it. `Write(...)` rules do nothing for file writes — only `Edit(...)` is recognised — so never turn a printed `Edit` rule into a `Write` one.

## The status event stream — the fifth source
`$JSC_HOME/usage/events.jsonl` is where every skill and every hook records how its run ended. A hook writes a skill's `start` for free; the matching `end` can only be written by the skill itself, in its own closing step. **So a `start` with no matching `end` is an aborted run, and it is the only evidence of one that exists anywhere.** That is what this source is for; the counts around it are secondary.
`{CURRENT}/jsc-assist/tools/patrol.sh collect` owns the whole of it — it calls `{CURRENT}/jsc-hooks/tools/report-status.sh drain`, then `rotate`, then does the pairing, and writes the 執行狀態事件 subsection into `latest_file`. **Never run `drain` from this skill.** Four properties make that the only safe arrangement, and each one is a way to lose events:
- **`drain` is a consuming read.** It prints everything written since the last drain and then moves the offset in `$JSC_HOME/usage/scan-state/events.offset`. The same events never come back. Read into a transcript instead of a file, they are one dropped line away from gone; a second `drain` in the same round returns exit 3 and the first drain's events are already spent.
- **Exit 3 means there were no new events, and that is a normal round, not a failure.** Most rounds have nothing new. The script also uses 3 when the stream file does not exist yet.
- **`rotate` has to follow `drain` immediately.** It renames the stream and resets the offset once the file passes its size limit, so anything appended between the two calls is moved aside without ever being drained. One script, one run, smallest possible gap.
- **Pairing is by `session` plus `name`, and it carries across rounds.** Five CLIs run the same skill in different sessions at once, so `name` alone lets one session's `end` cancel another session's `start`. And a round lasts about two minutes while a skill run can last much longer, so an unmatched `start` is held in `$JSC_HOME/assistant/events-open.tsv` and matched against later rounds. It is reported as an abort only once it has stayed open longer than the heartbeat TTL; below that it counts as still running.
Neither `drain` nor `rotate` may stop a round. A missing `report-status.sh`, a `drain` that returns anything other than 0 or 3, and a failed `rotate` each mark this one item failed or add one 警示來源 — exactly like the other four sources — and the round carries on to record itself. The reporting chain breaking must never break the round that is doing the reporting.

The six limits in `AGENTS.md`「助理的界線」 hold for all four operations. Four of them need saying out loud here:
- **This skill never judges a gate.** It maintains the heartbeat and prints what the heartbeat says. Whether a stale heartbeat blocks a skill call is decided by a hook, synchronously and offline; nothing in this skill blocks or waves through anything. 界線 2.
- **A patrol round asks nothing.** It runs from cron with nobody present, so there is no one to answer and a question hangs the round. Every branch in the patrol steps below resolves without a question: a missing source is recorded as missing, an ambiguous result is recorded verbatim, and a round that cannot proceed aborts and reports.

The directory page is a separate write in a separate wiki repo, and `wiki-contents.sh` does it: this machine's row is updated and nobody else's.

The round lock is the one thing a crash does leave behind, and it ages out the same way: `patrol.sh collect` breaks a lock older than the heartbeat TTL, takes it, and prints `lock_broken=1` so the takeover lands on the monitor page instead of happening quietly. The overrun round that lost its lock then gets exit 4 from `finish` and writes no heartbeat, which is correct — it never reached the end.
That property holds only while nothing fakes a heartbeat. **`write` is called by `$JSC_HOME/current/jsc-assist/tools/patrol.sh finish` and nowhere else.** `start` does not call it, `status` does not call it, `stop` does not call it, no scheduled entry calls it, and no other skill calls it. A heartbeat written by anything that is not a finished round says a round finished when none did, and the reader has no way to tell the difference. This is also why `stop` removes the scheduled entry before clearing the heartbeat, and never in the other order.

`start` proves the loop works before it schedules it: one patrol round first, then the scheduled entry. It installs no daemon and writes no bare heartbeat.
1.**Run one patrol round.** Follow every step of the `patrol` operation below, start to finish. This is what writes the first heartbeat — there is no shortcut past it, because a heartbeat that no round produced is exactly the lie this design removes. When that round ends without a heartbeat for any reason (`collect` exit 4, 5 or 6, an empty `hash=`, a failed write of the monitor page, a directory-row failure other than exit 3, or `finish` exit 2, 4 or 5), the start has failed: report the round's outcome and the code, do not run step 2, and do not claim a started assistant. A round that completed with failed items (`collect` exit 1 or 3) is still a completed round — carry on to step 2 and name the failures in the closing report. Completion condition: `patrol.sh finish` exited 0, or the failure report naming the step and the code has been printed and no start was claimed.

Any other state right after a successful round means something rewrote or removed the file in between: report the state, the path and that the heartbeat did not survive its own write, and do not claim a started assistant. Completion condition: the report line was read and either `state=fresh` was recorded with its seven fields, or the mismatch was reported.

1.**Collect.** Run `$JSC_HOME/current/jsc-assist/tools/patrol.sh collect --trigger 排程` (use `--trigger 手動` when a person asked for this round). Judge the exit code by the patrol.sh table. Exit 4 stands the round down — report the holder and its age from the printed `lock=busy` line, and stop; write no page and no heartbeat. Exit 5 and 6 stop the round the same way, with the code and the stderr text. Exit 0, 1 and 3 all carry on to step 2. Record `round=`, `lock_broken=`, `hash=`, `page=`, `verdict=`, `failed_sources=`, `warn_sources=`, `pending=`, every `item=` line, and the file paths `latest_file=`, `summary_file=`, `summary_row_file=`, `newpage_file=` and `contents_file=`. Completion condition: the round id, the page name and the five file paths are recorded, or the stand-down or the failure was reported and the round stopped.
1.**Collect.** Run `{CURRENT}/jsc-assist/tools/patrol.sh collect --trigger 排程` (use `--trigger 手動` when a person asked for this round). That is the same split step 0 branched on: 排程 is the unattended round that read its root out of the invocation text, 手動 the round somebody asked for. Judge the exit code by the patrol.sh table. Exit 4 stands the round down — report the holder and its age from the printed `lock=busy` line, and stop; write no page and no heartbeat. Exit 5 and 6 stop the round the same way, with the code and the stderr text. Exit 0, 1 and 3 all carry on to step 2. Record `round=`, `lock_broken=`, `hash=`, `page=`, `verdict=`, `failed_sources=`, `warn_sources=`, `pending=`, every `item=` line, and the file paths `latest_file=`, `summary_file=`, `summary_row_file=`, `newpage_file=` and `contents_file=`. Completion condition: the round id, the page name and the five file paths are recorded, or the stand-down or the failure was reported and the round stopped.
2.**Check the page name.** An empty `hash=` means `jsc-gitea/tools/hash-id` could not be found or could not run, so there is no page to write to and nothing can be recorded. Run `$JSC_HOME/current/jsc-assist/tools/patrol.sh abort --round {round}`, report that the round found its results but has nowhere to put them, name `jsc-gitea` as missing, and stop.
**The status event lines come out of the same call.**`collect` drained the stream and rotated it (see 「The status event stream」 above), so record `events_total=`, `events_bad=`, `events_unpaired=`, `events_running=`, `events_rotated=` and `events_file=` alongside the rest, and read `item=D-11` for whether that source was readable at all. The 執行狀態事件 subsection of `latest_file` already carries the two detail tables — the non-`ok` events and the starts with no matching end — so never rebuild either by hand and never call `report-status.sh` yourself: a second `drain` this round would either return exit 3 or eat events that then reach no page at all.
2.**Check the page name.** An empty `hash=` means `jsc-gitea/tools/hash-id` could not be found or could not run, so there is no page to write to and nothing can be recorded. Run `{CURRENT}/jsc-assist/tools/patrol.sh abort --round {round}`, report that the round found its results but has nowhere to put them, name `jsc-gitea` as missing, and stop.
**Never invent a page name, and never work the hash out by hand** — a hand-made name lands the content on a page nobody reads. `hash-id` hashes `{host}/{user}` and prints the full 40-character uppercase hexadecimal SHA-1: no truncation to 8, no `H` prefix, and an empty input exits 2 rather than hashing the empty string. So `page=` is either `MONITOR_` plus that 40-character string, exactly as the script printed it, or nothing at all. Completion condition: `page=` holds a `MONITOR_{HASH}` name taken verbatim from `collect`, or the abort ran and the round was reported as unrecorded.

Put the whole page. An old-format page — per-round sections stacked up, no summary table — has no rows to carry over: keep its `本頁基本資料` block, drop the stacked sections, let the table start with this round's row, and say in the report that the page was converted. Only exit 4 from the read permits creating the page instead, and then the body is the whole content of `newpage_file`, which already carries all three blocks. Exit 7 and exit 8 mean the old content is unknown: create nothing, write nothing — rebuilding a page from an unknown original throws the summary table away. On any write failure — including exit 3 with no wiki repo configured for `MONITOR`, which the patrol cannot ask about — run `$JSC_HOME/current/jsc-assist/tools/patrol.sh abort --round {round}`, report the code, and stop. **No record, no heartbeat**, and that verdict belongs to this step alone: the round's result lives on this page, so a repo this step cannot resolve leaves the round with nowhere to be recorded. Step 4 is judged on its own terms. Completion condition: the put or the create returned success and the page holds exactly three blocks with the summary table at 24 rows or fewer and this round's row on top, or the abort ran and the round was reported as unrecorded with its exit code.
**Verify the page's links before the write.** List every link the rebuilt body carries — the ones the latest-round block brought in, and any that survived in the block carried over from the old page — and run `{CURRENT}/jsc-gitea/tools/link-check.sh` over the whole list. Exit 0 is the only result that permits the write. On exit 1 report the `DEAD` lines verbatim, then run `{CURRENT}/jsc-assist/tools/patrol.sh abort --round {round}` and stop: a round that writes a dead link records a false trail nobody can follow back. Exits 2, 3 and 7 take the same abort, each reported by the rule B table above. A body carrying no link at all needs no call — say so in the report rather than claiming a check that never ran.
4.**Update this machine's row in `MONITOR_CONTENTS`, through `jsc-gitea/tools/wiki-contents.sh`.** That page is a directory every machine writes to, and it lives in the repo `gitea.sh wiki-repo CONTENTS` resolves — `JSC_WIKI_REPO_CONTENTS`, then `JSC_WIKI_REPO`, then exit 3, and never a fallback to `JSC_WIKI_REPO_MONITOR`. The script owns the read-match-write of one row, so never read this page and rebuild it by hand, never write it through `jsc-gitea:wiki`, and never rebuild it the way step 3 rebuilds the content page — every other row here belongs to a machine that is not this one, and one careless whole-page write deletes their records.

**Finish the row first.** The `row=` line in `contents_file` carries the placeholder `{監控頁絕對網址}` in its first cell, because the directory page and the monitor page now sit in two different wikis: `[[MONITOR_{HASH}]]` resolves only inside one wiki and would dead-link from here while still looking like a link, and the absolute URL cannot be known until step 3 has actually put the page. Run `$JSC_HOME/current/jsc-gitea/tools/gitea.sh wiki-url {the MONITOR repo step 3 resolved} MONITOR_{HASH}`, replace the placeholder with what it prints, and write the finished row to a file. Exit 4 there means step 3's write has not landed — go back to step 3 rather than writing a row. Exit 5 means the page carries no `html_url`: report it and never assemble a URL by hand. Exit 7 or 8: report the code and take the abort row below. **Any other non-zero exit takes the same abort row**, a missing argument included — a URL that never arrived would otherwise leave the link cell holding the raw placeholder, and the row would still be written.
4.**Update this machine's block in `MONITOR_CONTENTS`, through `jsc-gitea/tools/wiki-contents.sh`.** That page is a directory every machine writes to, and it lives in the repo `gitea.sh wiki-repo CONTENTS` resolves — `JSC_WIKI_REPO_CONTENTS`, then `JSC_WIKI_REPO`, then exit 3, and never a fallback to `JSC_WIKI_REPO_MONITOR`. The page carries no table: it is an H1, a `>` preamble, and then one H2 block per machine — the heading is that machine's monitor page name, and the fields are one `- {name}:{value}` bullet each underneath. The script owns theread-match-write of one block, so never read this page and rebuild it by hand, never write it through `jsc-gitea:wiki`, and never rebuild it the way step 3 rebuilds the content page — every other block here belongs to a machine that is not this one, and one careless whole-page write deletes their records.
**Finish the block first.**`contents_file` holds this machine's whole block — `## MONITOR_{HASH}`, a blank line, then the bullets — and its 監控頁 bullet already carries the rule A shape `[{page name}]({URL})` with the placeholder `{監控頁絕對網址}` standing in for the URL, because the absolute URL cannot be known until step 3 has actually put the page. Run `{CURRENT}/jsc-gitea/tools/gitea.sh wiki-url {the MONITOR repo step 3 resolved} MONITOR_{HASH}`, replace the placeholder with what it prints, and write the finished block to a file. Exit 4 there means step 3's write has not landed — go back to step 3 rather than writing a block. Exit 5 means the page carries no `html_url`: report it and never assemble a URL by hand. Exit 7 or 8: report the code and take the abort row below. **Any other non-zero exit takes the same abort row**, a missing argument included — a URL that never arrived would otherwise leave that bullet holding the raw placeholder, and the block would still be written.
**Then verify that URL before the block goes anywhere.** Run `{CURRENT}/jsc-gitea/tools/link-check.sh {the URL just substituted}` and read the exit code by the rule B table above. Exit 0 is the only result that permits the upsert. On exit 1 the directory would gain a block pointing at a page that is not there: report the `DEAD` line verbatim, write no block, and treat the directory entry as not updated — the round's own result is already on `MONITOR_{HASH}`, so carry on to step 5 and write the heartbeat, exactly as exit 3 from the upsert does, and put the dead link into the 待人處理 rows. Exits 2, 3 and 7 are reported the same way and the block is left unwritten. Never write the block first and check afterwards: the directory is what other people read to find this machine, and a dead link there sends every one of them to a page that does not exist.
Then run, with the template as the fifth argument every time:
**The key is column 2, the bare `HASH` cell** — the 40-character string `collect` printed as `hash=`, copied verbatim, with no link, no brackets and no URL around it. The script compares the whole cell text, so column 1 cannot be the key: that cell holds `GITEA_HOST` and the wiki's encoding of the page name, so a changed host, a `JSC_WIKI_REPO_MONITOR` pointed at another repo, or a different URL encoding changes the text and stops it matching. This page is written once every round, so from that moment on every round appends one more row for this same machine and the old row is never updated again. The bare `HASH` depends on `{host}/{user}` alone, which none of those three touch. Column 1's link stays in the row for people to click, and never for matching. A key typed by hand matches nothing either, and appends the same duplicate row.
**The key is the H2 heading — the page name `MONITOR_{HASH}`**, taken from `collect`'s `page=` line verbatim, with no link, no brackets and no URL around it. The script compares the heading text, so the 監控頁 bullet cannot be the key: it holds `GITEA_HOST` and the wiki's encoding of the page name, so a changed host, a `JSC_WIKI_REPO_MONITOR` pointed at another repo, or a different URL encoding changes that text and stops it matching. This page is written once every round, so from the moment matching breaks every round appends one more block for this same machine and the old block is never updated again. The page name depends on `{host}/{user}` alone, which none of those three touch. That bullet's link stays in the block for people to click, and never for matching. A key typed by hand matches nothing either, and appends the same duplicate block.
**The `1` is the third argument, `key-col`, and it only matters while an old page is still a table.** A directory page written in the previous format holds a markdown table, and the script converts the whole page to blocks before it upserts; `key-col` tells it which column of that table held the identity, counting from 1. Column 1 of this page's old table was the monitor-page link, whose cell is `[MONITOR_{HASH}]({URL})`, and the conversion takes the text out of it as the H2 heading. Once the page is in the block format the argument is ignored — pass `1` regardless, and never a column number worked out from the current page.

Completion condition: the script exited 0 and exactly one row carries this machine's bare `HASH`in column 2 with this round's values, or exit 3 was reported as an unwritten directory row and the round carried on, or one of the other non-zero codes — `wiki-url`'s included — was reported after the abort ran.
Completion condition: `link-check.sh` exited 0 over the block's URL and the script exited 0 with exactly one `## MONITOR_{HASH}`block on the page carrying this round's values, or exit 3 from the upsert or a non-zero `link-check.sh` was reported as an unwritten directory entry and the round carried on, or one of the other non-zero codes — `wiki-url`'s included — was reported after the abort ran.
5.**Write the heartbeat.** Run `$JSC_HOME/current/jsc-assist/tools/patrol.sh finish --round {round}`. This is the last step for a reason: it is the only thing that turns a fresh heartbeat into a true statement. Judge the exit code by the patrol.sh table — 2, 4 and 5 all mean the round is recorded but unproven, and each has its own report line there. Completion condition: `finish` exited 0, or the failure was reported as "recorded but no heartbeat" with its code.

6.**Report the round.** Print the round verdict and, when it is `警示`, the `warn_sources=` text that says why — a round can read all four sources and still come out `警示`, and that column is the only place the reason appears; then one line per item with its `status=` and, for a failure, its `note=`; the monitor page name, and the directory row as `updated`, `added`, or not written with the exit code and the reason; whether the heartbeat was written; and, when `lock_broken=1`, that the previous round's lock was taken over because it had aged past the TTL. Close with the 待人處理 rows from the latest-round block, verbatim, and nothing else — the patrol names an entry point and stops there. Completion condition: all four items appear in the report, the heartbeat outcome is stated as written or not written, and no suggestion in 待人處理 was acted on.
6.**Report the round.** Print the round verdict and, when it is `警示`, the `warn_sources=` text that says why — a round can read all five sources and still come out `警示`, and that column is the only place the reason appears; then one line per item with its `status=` and, for a failure, its `note=`; the monitor page name, the link-check verdict for each of the two writes — passed, skipped for a body with no link, or refused with its exit code and its `DEAD` lines — and the directory entry as `updated`, `added`, or not written with the exit code and the reason; whether the heartbeat was written; and, when `lock_broken=1`, that the previous round's lock was taken over because it had aged past the TTL.
**The event numbers get their own line, and the unpaired starts get their own list.** Print `events_total=` and `events_bad=` as this round's event count and its non-`ok` count, then every non-`ok` event with its `kind`, `name`, `status`, `exit` and `detail`, then — separately, never folded into the same list — every start with no matching end, by `name` and `session`. A non-zero `events_unpaired=` is the round's most important finding: each row is a skill run that started and never reached its closing step. Say `events_rotated=` too when it is `rotated` or `failed`. When `item=D-11` failed, say the source could not be read rather than reporting zero events — zero read events and zero existing events look identical in a report and mean opposite things.

1.**Read the heartbeat through the script.** Run `$JSC_HOME/current/jsc-hooks/hooks/heartbeat.sh report` and split the line on spaces, taking `file=` last so a path containing spaces stays intact. Map `state=` to the verdict: `fresh` → `新鮮`, `stale` → `過期`, `invalid` → `心跳檔損壞`, `absent` → `不存在`. Print `助理未運行` for `stale`, `invalid` and `absent`. Never re-derive the verdict from `ts` yourself, and never treat `invalid` as fresh. On exit 2 or 6, follow that code's row, record the heartbeat state as unknown, and carry on to step 2 — the task book is still worth printing. Completion condition: the heartbeat state holds one of `新鮮`, `過期`, `心跳檔損壞`, `不存在` or unknown, and `ts`, `age`, `ttl`, `pid`, `cli`, `session` and `file` are recorded as read or as empty.

On exit 2 or 6, follow that code's row, record the previous state as unknown, and carry on to step 2. Completion condition: the previous state and its fields are recorded, or the previous state is recorded as unknown with its code.

Judge the result by the schedule.sh exit-code table, and keep `removed=` and `others_kept=` for the report. On any non-zero code the schedule is still installed: report the code, say plainly that rounds will keep running and the assistant therefore cannot be stopped, name the manual fix (`crontab -l` to look, then remove the line carrying `# jsc-assist:assistant` by hand), and skip steps 3 and 4 — clearing a heartbeat that the next round rewrites only hides the problem. Completion condition: `remove` exited 0 with its counts recorded, or the failure report has been printed and no stop was claimed.
