Go build module: the compose test gives its module a slot, since a node with no capacity set now pulls nothing (issue 1126, ADR 0567 §15)

The test built its module with no settings file and no Capacity; the new
buildstep.NodeCapacity answers 0 for that (no default names a node), so the
puller took no ask and the test timed out after 90 s in check 205f634c30df.
Failed first locally at origin/main af89893d (90.1 s), passes with the slot (2.5 s).

A seat the mesh holds once is `<seat>.<verb>` (the mesh's own verbs\n  are `mesh-controller.<verb>`: `status`, `plan`, `node`, `assign`, `push`, `settings`);\n  a module on a machine is `<node>/<module>.<tool>`.\n- `mesh_overview` and `mesh_machine` — the mesh's seats and machines, and what one machine runs.\n\n- **Symptom first.** For an error, a failing service or anything unexpected, search the record with the\n  literal text before forming a hypothesis: the records module's `records_search`, then\n  `records_read`.\n- **Ask the mesh before changing it**, and change it through the controller's verbs or the catalog.\n- **A licence** through the `anthropic-licence-manager` seat's verbs. Never edit the agent's credentials\n  file by hand, never print or ask for a token.\n\n## Hard rules\n\n- A file the mesh manages is changed through the verb or the catalog that owns it, never on disk. If\n  unsure, `mesh-controller.plan` for the node says what the mesh writes there.\n- Never write to a store's database by hand; schema changes are numbered migrations.\n- Never push to a main branch: a branch, a pull request, and a human approval for every merge.\n- The mesh creates no symlinks, and nobody else does either.\n- A package is declared in a module, never installed by hand.\n\n## Conventions\n\n- Commit messages are concise, in the imperative, about why.\n- Test before pushing: nodes update unattended.\n- The playbooks in the record say how research, decisions, designs, issues and hand-offs are done.\n"

@@ -275,6 +275,70 @@ reported no key gets no entry, and its client says it waits. Keys titled `mesh:`
 a key added by hand never is. Every consumer is made again every ten minutes and at once when a key changes.
 `go test ./cmd/forge-account-provider ./internal/forgeaccount` runs it against a fake forge.
 
+## The mesh's accounts read every repository (the operator, 2026-10-26)
+
+The tools act as the plain account `mesh-tools` (ADR 0365 §2, issue 469), which writes to the organisation `novox`
+through its team; the build modules fetch over ssh as `nox-builder` (ADR 0466 §3), in a team that reads the
+organisation's code; the machines' agents use `nox-agent` (ADR 0410 §1). Any other repository each saw only when public,
+so a private repository of a user answered every tool 404 and every build's fetch "not authorized to read". `readall.ts`
+makes each of these accounts (one list, `meshAccounts` in `tools-account.ts`, whose two Go names
+`internal/forgeaccount`'s test holds to its own constants) a collaborator that **reads only** on each repository it
+cannot read: one repository at a time, no organisation membership, the least the forge offers. An account the forge
+does not hold yet (the forge-account provider makes `nox-builder` and `nox-agent` when their first consumer asks) is
+named and asked nothing; the start's pass is run again ten minutes apart until every account was there once.
+
+- **When:** one pass over every repository of every user and organisation at the start (a forge not answering yet is
+  asked again a minute apart until one pass ran), and on the forge's system webhook: `forge.repository.created` and
+  `forge.fork` at once, and the first event of any repository this process has not seen readable (the forge may not
+  send a creation for every owner). Nothing polls for it.
+- **Not caught:** a repository made private after it was seen readable. The forge sends no event for a change of
+  visibility, and the start's pass already saw it readable, so its events ask nothing. It is granted at the module's
+  next start, or now by `gitea_grant_read`; `gitea_unreadable_repos` shows it meanwhile. A repository whose permission
+  the forge will not answer is named as refused (or, in the listing, with permission `unknown`) and the pass goes on.
+- **With what:** the site administrator's login (`MESH_GITEA_ADMIN_PASSWORD_FILE`), because adding a collaborator asks a
+  repository's administration, which on another user's repository only the site administrator holds. It is used for
+  five calls alone: list every repository, read one, whether an account exists, read an account's permission on one,
+  add an account as a read collaborator. The tools' own calls keep their token.
+- **Tools:** `gitea_unreadable_repos` (per account, every repository it cannot read, the permission the forge gives
+  it there and why, a count per account and the accounts the forge does not hold) and `gitea_grant_read` (the same
+  grant by hand, now, on every repository or on those named, for every account or those named; each grant read back
+  from the forge, a refusal answered in the forge's own words).
+
+### Teams are read with the administrator's login
+
+`gitea_team_rights` (issue 1563) answers the forge's teams of an organisation (novox when not given), or one team: its
+members, permission, units (read, write or admin per unit), whether it covers all repositories, and whether it is
+read-only. With a `user` it adds the teams that user is in and its effective right on every repository (or those named),
+listing those above read: the check that a build key's user, `nox-builder` in `builders`, reads and pushes nothing. The
+tools' token lacks `read:organization` (the forge answers 403), so the read goes with the administrator's login, GET only.
+
+### Two settings have named tools, and a retargeted pull request is judged again
+
+`gitea_api` refuses a repository's settings and a pull request's base (guard.ts). Issue 1422 note 7 gave each its tool:
+`gitea_default_branch_set` (owner, repo, branch, why) and `gitea_pull_base_set` (owner, repo, number, base, why). Both
+act as the tools' account, need a reason, refuse a branch the repository does not have, and answer the value before and
+after; a default must also be a branch a protection rule guards, and only an open pull request has its base changed.
+A pull request's announced head is kept under `owner/repo#number@base`, so a retarget (same head, new base) is
+announced again into the new base by the next poll instead of being skipped as already announced.
+
+### The merging account writes the repositories the mesh delivers
+
+`mesh-tools` sets every commit status and merges; outside the organisation it only reads (above), so a pull request of
+a user's repository could be checked and asked but never merged (issue 1945: car-hunter #2's status refused 403 after
+the operator's Approve). `writes.ts` makes it a collaborator that **writes** on each repository that builds a registered
+module, and on no other (the operator, 2026-10-26): the build modules' and the agents' accounts keep read.
+
+- **Which:** the indexer's state `mesh-delivery-indexer.modules` (in this module's `reads`), one key per registered
+  module, each naming its repository. A repository of `novox` needs nothing: the team writes it. Every other repository
+  of a user stays read-only.
+- **When:** the state's watch hands every module at the start and each one registered after; a repository not yet
+  written is granted then, read back from the forge, and said on the bus as `gitea.repo.writable` {owner, repo,
+  account}, on which mesh-delivery-gate reads that repository again. Nothing polls.
+- **Tools:** `gitea_unwritable_repos` (every delivered repository the account cannot write, its permission and why)
+  and `gitea_grant_write` (the same grant by hand, on every delivered repository or those named; what it granted, what
+  was written already, what the forge refused in its own words, and the repositories left read-only and why).
+  `gitea_commit_statuses` answers `merge.writes`, whether the account may write the repository at all.
+
 ## Files it does not know
 
 Each directory or archive this module declares says how it treats a file it did not write (ADR 0422, ADR 0416).

+//
+// **Every account the mesh's parts use, from one list** (MESH_ACCOUNTS, tools-account.ts): the tools' `mesh-tools`, the
+// build modules' `nox-builder` (their fetch over ssh, ADR 0466 §3) and the machines' `nox-agent` (ssh-client's key,
+// ADR 0410 §1). The first pass granted the tools' account alone, so the build modules' fetch of jschoubben/car-hunter
+// still failed on ace and g14 ("nox-builder ... is not authorized to read"). The two Go names are the ones of
+// internal/forgeaccount, whose test holds the list to them. An account the forge does not hold yet (its consumer never
+// asked) is said and left out, never a refusal per repository.
+//
+// Since issue 469 the tools act as the plain account `mesh-tools`, which writes to the organisation novox's
+// repositories through its team (tools-account.ts). Every other repository it saw only when public: a private
+// repository of a user (jschoubben/car-hunter, jschoubben/snake) answered its tools 404 and was missing from every
+// list, while that user's public ones were there. So the module makes its account a collaborator that reads only on
+// each repository it cannot read, the least the forge offers: one repository, read, no organisation membership.
+//
+//   - **at the start**, one pass over every repository of every user and organisation;
+//   - **on the forge's own event** (the system webhook, webhook.ts): `forge.repository.created` and `forge.fork` at
+//     once, and the first event of any repository this process has not yet seen readable, since the forge may not
+//     send a repository's creation for every owner. Nothing polls for it.
+//
+// **Not caught: a repository made private later.** The forge sends no event for a change of visibility, and a public
+// repository is already seen readable by the start's pass, so its events ask nothing. Such a repository is granted at
+// the module's next start, or now by `gitea_grant_read`; `gitea_unreadable_repos` shows it meanwhile.
+//
+// **The grant needs the site administrator's login.** Adding a collaborator asks the repository's administration,
+// which on another user's repository only the site administrator holds; the module holds that login for setting the
+// forge up (MESH_GITEA_ADMIN_PASSWORD_FILE). Here it is used through `ReadAllForge` alone: list the repositories, read
+// the account's permission on one, add the account as a collaborator that reads. Nothing else, and never for the tools'
+// own calls, which keep their token.
+//
+// What the forge refuses (a repository that went meanwhile, an archived one if the forge will not take a collaborator

+// **A bus of its own.** The integration level runs every directory's tests at once on one bus, and this test names the

+// **The order is read from the record.** At capacity 1 the puller starts the check the instant the delivery ask's step
+// ends, well before any poll, so "the check key holds a state" is true on correct behaviour (issue 1887). The test
+// waits for both asks to end and compares the step records' own Started and Ended times, and the fetch order by commit.
