Only issues at +`open`, `diagnosing` or `located` that are older than the new one are offered; a resolved or wontfix issue is +never offered, linked or noted. + +| verdict | done, through the module's own `note`, `link` and `move`, each recorded as by `duplicate-check` | +|---|---| +| `duplicate`, certain | the verdict noted on the new issue; linked `duplicates` to the older; its title and report noted on the older; moved to `wontfix`, reason "duplicate of N" | +| `related`, or `duplicate` not certain | the verdict noted; linked `relates-to`; noted on the older; nothing moves | +| `none` | one note: checked against so many issues | + +The older issue never moves. The verdict note is written first, its first line in a fixed form (`Duplicate +check: duplicate of N.`), so a second delivery of the event, or the backlog's pass, does only the steps not yet +done and never judges again. A judgement that fails — no answer, a late one, an answer outside the shape, an +issue not offered — leaves one note saying why, and the event is not taken: the bus offers it again, and after +its fifth delivery the controller raises `max-deliveries` on the module's consumer and keeps the event for a +person to deliver again. + +`groom` runs the same judgement over every issue not resolved and not yet checked, oldest first, against the +older ones not resolved and not found a duplicate in the same pass. It writes only the pass, in the state +`grooming` (the last pass, one key), and applies that pass's findings on `confirm` — never a fresh judgement. +A finding whose issues have moved on is skipped and said. It adds no "none" note to the backlog. + +The tracker asks one judgement at a time; the pass waits while a new issue's check is waiting, and one verdict is +applied at a time. A check may take up to a minute (two judgements of at most 25 seconds each), which the tool +runner allows a handler while keeping its event alive (hq issue 387). + +## The import of hq's issues (slice 3) + +`issue-tracker.import` reads every `04-ISSUES/NNN-slug/00-report.md` of hq **through the records module +over the bus** (`records_status`, `records_list`, `records_read`, called as this module through the SDK's +`Ask`), at the commit the records module's checkout stands at, and writes each as an issue **at its own +number**: `record` is the folder, the title is the report's heading, the report is the text under it, and +`status`, `opened`, `located-in`, `fixed-by`, `amended-design`, `replay` and `replay-none` are the +frontmatter's, as written — the status one to one, no cycle rule applied, because the folder's status is +the snapshot hq kept. The issues and decision records the report names (`issue 155`, `ADR 0275`, +`04-ISSUES/203-…`, `02-DECISIONS/0019-…`) become `relates-to` and `decision` links. + +It is a verb on the seat, callable by any agent, because it can do only this: + +- **It only creates an issue that is not there** (`create` on the key, refused when the key exists) **or + fills the status of one the tracker holds without a status** — an issue opened with a folder before this + slice, whose folder kept its status; one whose folder hq does not hold at the commit becomes `open`. +- **It never overwrites.** An issue the tracker holds differently is reported as `differs`, naming the + fields, and left alone: the tracker is the truth. An issue it holds the same is `same`. So a second run + changes nothing and says so. +- **It never touches the counter**, and refuses the whole run when a folder is numbered past the counter. + A folder numbered at or past the setting `first-number` without an issue in the tracker is refused on its + own: a folder from the tracker's time carries a number the tracker gave. +- **It cannot forge an issue's history.** An issue it writes is `opened-by: import`, its `opened` the date + the report gave, and it carries `imported: {at, by, commit, from}` — when, who ran the import (the bus + credential, `unproven` until the runtime proves it), the commit of hq and the document. Each is an + `imported` event. What it writes comes from hq's `main` as the records module holds it, which is reviewed + in pull requests. +- **What it keeps is bounded** as every verb's text is: the title 200 bytes, the report 64 KiB, one issue + 256 KiB; a report that trips a credential's shape is refused. An entry of `located-in` or `fixed-by` hq + wrote is prose at times, so it is taken within a reason's bound (2000 bytes), not a line's. +- **An owner hq named that the registered list does not know is kept as written and marked**, in + `located-in-unverified` on the issue and `unverified-owners` in the answer, never refused: the list is + the setting's problem (hq issue 366), and a `move` that gives `located-in` anew checks every entry and + clears the mark. +- **With `dry-run`** it reads everything, writes nothing, and answers the same rows with `would-` on each + action. **With `commit`** it refuses a checkout standing elsewhere; it refuses a run during which the + checkout moved. + +The answer is a row per folder — number, action (`create`, `fill`, `same`, `differs`, `refused`, with why), +status, title — the counts, the counts by status, what was odd (a title numbered otherwise than its +folder, a frontmatter key not imported, an `amended-design` that is no design document) and the unverified +owners. A call that outlives the tool runner's wait is still running: the import goes on, and the answer +is read back through the controller's `calls` verb by the call's id. + +Before the module is rolled out, `mesh-issues dry-run ` at the terminal runs +the same dry run over a checkout on disk against an empty tracker, and prints the answer. It is not a way +to import: only the verb writes, and it reads the record over the bus. + +**Every argument is read strictly.** One a verb does not take is refused, never dropped. Every field has a +size limit, a one-line field takes no control character, a folder's name is no path, and text shaped like +a credential (a private key, an API key, a forge or bus token, `password=…`) is refused: an issue is read by +every agent on the mesh. The shapes catch the ordinary mistake, not every secret. + +## Numbers + +One counter, the key `issue` of the state `counters`, advanced only by compare-and-set: the SDK's +`State(...).Increment` reads it and writes the next number only at the revision it read, so two openers — +in one instance or two — never take one number. A write another opener won is read and tried again, a +bounded number of times with a short random wait; past the bound the open is refused and takes no number. + +- **A refused open takes no number**: an issue is checked before its number is taken. +- **A number is never handed out twice, and may be skipped.** A number taken and then not kept — the bus + failing between the counter and the issue — stays unused, and the answer says which. A write whose answer + was lost is recognised as its own when tried again, so it leaves no gap; when it cannot be confirmed either + way, the answer says the issue may have been written and to `get` that number before opening it again, + never that nothing was opened. +- **An issue is never overwritten.** It is kept by a write that is refused when the key exists; if the + counter ever hands out a number already kept, the open is refused loudly, the number stays unused, and + nothing is overwritten. +- **The counter starts once**, the first time a number is taken: at the setting `first-number`, or after + the highest issue already kept, whichever is higher, made only if it does not exist. The setting is never + read again, so a number never moves. + +## State and events + +Two states, declared in the manifest and made by the controller; the module never makes a bucket +(ADR 0201): `issues`, one key per issue by number, keeping 8 values per key; `counters`, one value per key. +Neither expires. One issue is kept in at most 256 KiB; a note that would pass it is refused. + +Every change is an event: `mesh-issues.opened`, `.moved`, `.noted`, `.linked`, `.imported`, each with the +number, what changed, who changed it and when. The events are the audit trail. A change whose event the bus did not take +is kept, and its answer says the event was not said (`announced: false`). + +## Who acted + +ADR 0275 §5 records the caller from the bus credential, never from an argument. **The runtime does not yet +tell a module who called it**: a tool call reaches a bundle as a name and arguments, and the tool runner is +not told who called it either (hq issue 340). Until it does, every change is recorded as by `unproven`, no +verb takes an argument naming a caller, and none can be given one. + +## Settings + +`duplicate-check` (`on`; `off` stops the check on new issues) and `judge-model` (`sonnet`; `haiku` or `opus`) +steer the duplicate check. + +``` +{ + "first-number": 365, + "owners": ["hq", "mesh-catalog", "mesh-catalog modules/nats", "mesh-controller", …] +} +``` + +- `first-number` — the number the first issue gets: the one after the highest issue number on hq's main + and every open branch at the moment the module is switched on. Read once for the counter; the import + reads it as the boundary between the folders hq numbered before the tracker and the numbers the tracker + gave. +- `owners` — the registered list `located-in` may name: repositories, and modules as + `mesh-catalog modules/`. An entry of `located-in` is an owner, or an owner followed by a space or a + slash and where in it (`mesh-controller internal/broker`, `mesh-catalog modules/nats/module.json`). A module + must itself be registered: `mesh-catalog modules/` is never taken as a place in `mesh-catalog`. It starts with the mesh's repositories and the modules + the catalogue held when this module was written; a module added since is added here through the + controller's settings verb. + +## Tests + +`go test ./...` in this directory. The acceptance — an agent opens an issue and gets the next number; two +agents opening at the same moment never get the same one — is +`TestFiftyOpensAtOnceFromTwoInstancesGetFiftyDistinctConsecutiveNumbers`: a JetStream server linked into +the test, two instances of this bundle (the test binary started again) speaking to a runtime played by the +test against the buckets the manifest declares, fifty opens at once, fifty distinct numbers from the first +in a row. It counts the writes lost to another opener, so it fails when the openers never collided.

The first capability the new work depends on is present, +declared, and unusable — and would have stayed unusable silently. + +It also generalises. Every module that declares a package needing a unit enabled, a group +joined, a kernel module loaded, or a socket activated has this gap.

The screenshot tool of the + display server failed for one window with `X Error BadColor (invalid Colormap parameter) + X_QueryColors`, because it dumped the window by its id. +3. **The symptom's cause is not known yet.** A reminder that shows nothing is a missed meeting. + +The diagnosis is in [01-diagnosis.md](01-diagnosis.md). + +## Impact + +- The operator cannot read or dismiss a meeting reminder: the window is there but empty. +- Until now, the next session that looked at it had to work around the mesh to see a window. + +## What is done + +- The display server's module gains a window list that includes unmanaged windows with their depth, + type, state, role and own opacity, and its screenshot of one window is cut from the screen as the + compositor shows it (catalogue pull request, linked from this record's pull request). +- A `betterbird` module: status, named preferences without credentials or accounts, a user.js declared + through the module's setting, its log, restart, check, and a reminder on demand from a throw-away + profile, so a fix can be proved without touching the operator's calendar. + +- The `picom` module's backend and damage tracking become settings of each machine (defaults unchanged: + `glx`, `use-damage` true), so the candidate fixes can be set and proved without a hand edit. + +What is not done: the cause, and so the fix.

Both had passed +their checks. + +`mesh-delivery.deliveries` then showed every delivery of the dunst pull request `superseded`, and the +claude-code delivery `held`, waiting for "a person: merged, and the controller opened no walk for it within +10m0s — nothing it holds follows that branch, or the merge was not heard: a person decides". The +controller's `plans` said of the walk for the catalogue's head, which carried both merges: "published; its +walk waits for mesh-delivery's word — `plans go … --why …` starts it by hand". + +Both reasons were wrong. A walk had been opened, and it contained the held merge. Nothing gave it the word. +The operator's change sat undelivered for 58 minutes, until the operator's hand-act `mesh-controller.plans +go` started the walk. **No condition asked anyone to act in that time**: the hold is bounded at 24 hours +before `mesh-delivery.stalled` lists it, and the walk's own wait raised only a warning, at 00:51, which said +there was nothing to do and pointed at the ended delivery (the diagnosis's second entry; this sentence said +before that the walk's wait raised nothing). + +## Why it is an issue + +A merge that passed its checks must reach its nodes without a person, and a delivery that cannot must say +so loudly and truly. Here both failed: two ordinary merges close together, which happens whenever the +operator merges a batch, stopped the mesh's delivery silently, and the reason it gave pointed away from the +cause. + +## Where it lives + +The diagnosis ([01-diagnosis.md](01-diagnosis.md)) traces it to two parts that each behave as written and +disagree on what a walk's commit means: + +- The controller plans a merge it hears after a later merge of the same branch at the later merge's commit, + and supersedes the earlier walk (the fix for + [issue 349](../349-a-merge-acted-on-late-superseded-the-merge-after-it-and-built-the-older-commit/00-report.md)). + So the claude-code merge got a walk at the dunst merge's commit. +- mesh-delivery finds the delivery a walk walks by its walk id or by the commit it was merged as. The new + walk matched the dunst delivery, which its first walk's supersession had already ended, so no live + delivery held the walk and nothing gave it its turn. The claude-code delivery, merged as a different + commit, never got a walk and was held after ten minutes. + +## Open + +- How mesh-delivery learns which merges a walk carries: the controller's walk record naming every merge it + answers (its commit and the commits planned into it), or mesh-delivery reading containment itself, as it + already does to decide *covered*. +- A superseded walk whose successor matches only final deliveries: whether the successor should be adopted + as a delivery of its own, so that something always holds a waiting walk. +- A walk waiting for mesh-delivery's word past a bound, and a delivery held because no walk was opened, + raise a condition to the operator instead of waiting silently (failure must be loud). + +## Decided + +The operator decided the model that removes this shape, not only its bookkeeping: +[ADR 0276](../../02-DECISIONS/0276-merges-are-assembled-in-a-rolling-window-and-each-batch-is-delivered-by-one-walk-with-one-commit-per-repository.md). Merges are collected in a rolling merge window and each batch is walked once, with at most one +commit per repository, one walk at a time. The bookkeeping that tied a walk to an ended delivery is repaired as +well, and every wait of this shape has a bound and a condition. It is designed in to-be 47, *The merge window +and the batch*. + +## Resolved + +2026-10-10. mesh-delivery's side is mesh-catalog#171 (merged): a walk is tied to every live delivery whose +merge it answers, never to one that has ended, and a waiting walk no live delivery holds is listed by `stalled` +at once. The controller's side is mesh-controller#197: the merge window and the batch, one walk per batch with +one commit per repository, the walk naming every merge it answers, and the bounds of decision 9. The replay +R362 is registered in mesh-lab's replays register (mesh-lab#75), proved to fail on the commit before the +mesh-delivery fix and pass on it.
