After each reading of a licence with consumers whose session or weekly
window is at or above switch_at_pct, the manager moves every consumer bound
to it, when switch_auto is on and the settings are valid, to the other
licence with known room whose windows are both below room_below_pct and the
most room, the first by name on a tie. Each consumer moves as the switch verb
does, by usage, and says binding.changed; the act says one licence.switched
and one audit entry switched with the window, its percentage and reset and
the target's room, and is told to the operator; the switch verb is not told.
By hand the rule runs with switch_auto off, and dry answers the moves alone.

The settings gain switch_auto, switch_at_pct, room_below_pct, warn_at_pct,
usage_minutes and usage_stale_minutes with the manifest's defaults and
bounds, a value outside its bound keeping the default. The settings file is
read again at every reading, each changed value written in the audit under
settings, and the usage timer follows usage_minutes. A room or warning above
switch_at_pct is found as an invalid pair naming both values.

The usage reading flattens the session, weekly and sonnet windows each with
its reset time, keeps it beside the licence with when it was read, and says
it as usage.read; a failed answer keeps the last percentages and writes the
vendor's status and reason. A licence's room is 100 less the higher of its
session and weekly windows, known only for a subscription read within
usage_stale_minutes whose refresh is healthy; an API key's is never known.

The manager consumes the agent module's holdings-changed, keeping each report
as its node's latest and considering them at once, in place of reading the
agent module's state; once it hears them, at every start after its
carry-over, it says holdings.asked with its time and who asks, so every node
says what it holds again.

Each binding the verb bindings answers carries its licence's key beside the
§3 fields, as binding.changed does, so the vault's first view matches a
token's secret name to the binding without the key form of its own.

Bind, switch, release, a login's move and a rotation's advance each say one
binding.changed per consumer moved, with the licence's key, after the key of
bindings is written or deleted; a switch through the verbs says one
licence.switched with the from, to, consumers, by and why the audit's
switched entry also holds. licence.bound, released and rotated are said no
more. An adoption advances the consumers already bound before it moves the
login's nodes, so each is said once.

At its first start the manager reads the six tables of its database, read
only, and writes them into its kept data and its grants into the vault at
generation 1, then carried.postgres; until then only its read verbs answer.
A second start never opens the database, and a stopped run is done again
whole without doubling a log entry. The store's write code and its postgres
test go: nothing writes the database again.

Every reading is appended under its licence's key with the vendor's answer whole (ADR
0054), and every act under its kind, never rewritten; an act whose audit entry the log
does not take fails and says so. The memory store goes: the tests run the bus store over
a bus kept in memory.

A lease is a key created with a two-minute lifetime, which fails while another holds it:
the bus's own compare-and-set keeps one rotation source (ADR 0183 §6). An offered grant's
outcome is kept under its fingerprint in the key form for 90 days, every outcome kept.

The state licences holds one key per licence by its key form, never a secret, with its
latest reading beside it; the state bindings, the same local name the consumers read,
holds each consumer's licence, kind, generation, since, why and by, written by the store
itself. Each consumer counts its own generations, past what its node reported.

The manager hands what the vendor answers to licence-put, the grant first and then the
access, at the licence's next generation, and reads a grant with get for one act; it keeps
no token at rest (ADR 0550 §3). The sealing at rest goes; opening stays for the carry-over.

The vault hands every token (ADR 0550 §3); current names the licence, its key, kind,
generation, health and access expiry, and keeps the account's identity for the agent's
account file. bindings takes an optional consumer, answered unpaged.

Eight bus-state entries in the typed long form; the old state and the reads of
claude-code.holdings go, and so does the run-once prepare, since nothing writes the
tables again. The database and grant-key stay as the carry-over's read-only source.
The manifest declares its new events, its consumption of holdings-changed, the
operator channel it uses, the verbs it invokes, six settings and its eight tools.

A key of the bus takes fewer characters than a licence's name; the key is the store's

A switch of g14 back to another licence on 2026-10-13 left no trace: the manager logged no line and sent no event for bind, switch or release, and its audit kept only the verb's name. Every change of what a consumer holds now goes to the journal, the audit and a licence.<what> event with the same fields: consumer, licence before and after, generation, why (the verb or the rule) and by (the caller the runtime proved, or the manager itself). The node is told why in the bindings state and says it when it applies. The audit and binding tables become readable through the store's reader. The SDK moves to the version that proves the caller (issue 365).
mesh/merge-gate pass: builds claude-code, claude-licence-manager, restic → ace, g14, novox, shanks; no bus step; every machine composes with the change as …
The check looked for "rt" in a random base64 ciphertext, which holds it
about one time in seventy, and failed mesh-catalog #141's repo check by
chance.
On the control node agents are to run as an account that cannot become root
(hq ADR 0266). The runtime keeps running as the operator, so the token, the
identity and the home-scope items go to the agent's home through a helper
started as that account; the licence and the account file follow the move,
what was placed in the operator's home goes once the agent holds the licence,
and the guard refuses every tool of a session running as anyone else,
recording to the journal. An API key is taken only from the agent's home and
only when it is one, here and in the licence manager, so the tool cannot carry
off the runtime's credential. Unchanged where no agent account is named.
A licence store rebuilt after issue 241 counted generations from one again,
and nodes that apply only a higher number discarded the login move and the
rotations unseen. Nodes now apply any binding other than the one applied;
the manager moves its sequence past every generation a node reports. hq
issue 243.
The manager binds the node a login was adopted from to that login's licence,
switching it if it was bound to another; serves public_key; adopt takes a
key sealed to it. claude-code gains claude_code_add_api_key: read a file on
this node, seal, hand to adopt, remove the file, optionally switch here.
Found going live: the other nodes report the adopted account with older
logins, which are never candidates, and the first binding was only made at
adoption — so a node reporting afterwards was never bound (ADR 0206 §7).
The module is one Go binary the runtime launches: the renderer (its
instruction file held byte for byte to the TypeScript one it replaces),
the credentials and identity files, the licence flow of ADR 0206 and the
MCP servers in state. Keeps the TypeScript module's key files, so a node
moving to it keeps its key. The npm package, its tests and its build go.
Both binaries were run together under the real runtime on a test bus with
postgres and a stub vendor: a login was adopted by one exchange, the node
bound and handed an access token, its file left with no refresh token, and
no token in either state.
claude-licence-manager holds the anthropic-licence-manager seat: it reads
every node's holdings state, adopts a login it does not hold by refreshing
it (newest first, once per account), keeps each grant alive under a lease,
publishes what each consumer should hold as its bindings state with a
generation, and answers current sealed to the consumer's key. Postgres
store prepared by a run-once step; grants encrypted with the vault's key.
claude-code reports what its node holds (fingerprints and account, never a
token), hands its grant over only when the manager asks, watches its
binding and fetches the token on a newer generation, and writes
access-token-only. Its ask now reads the runtime's answer as a value and
addresses seats as seats.
