* docs+ux: make device ownership discoverable end to end
Complete the #1320 agent experience so 'busy? -> inspect -> choose or
release' is discoverable from every surface an agent actually reads:
- devices now projects the blocking claim owner per row (claimedBy with
session and workspace, observe-policy projection; provably dead owners are
excluded because the next open replaces them automatically), so an agent
told a device is busy can pick a free one from the same listing.
- help debugging gains a 'Device busy and ownership' section separating the
two DEVICE_IN_USE flavors and their exact recoveries.
- AGENTS.md documents both flavors; docs/agents/device-verification.md
retires the last ps/kill recovery guidance in favor of device status,
daemon stop --state-dir, and device release --stale (Stage 5 of #1320).
- ADR-0010 no longer calls DEVICE_IN_USE 'the only retriable code' without
naming the claim path's non-retriable override.
- The rendered cross-worktree claim error gains a help-conformance quiz case
binding (sample-output-device-claim-inspects-owner).
- README points at device status / device release --stale.
Part of #1320.
* fix: key ownership projection by canonical device identity end to end
Review findings on #2165:
- blockingClaimOwnersByDevice keyed claims and inventory rows by bare
device.id, so a live Android claim could project claimedBy onto an
unrelated same-id Apple/Harmony/Vega row, with scan order picking the
displayed owner. Both sides now use the canonical local device key
(claim.deviceKey against canonicalLocalDeviceKey of the row's claim
identity). The cross-family same-id regression was observed red against
the bare-id keying.
- The projection is now asserted across every hop the PR promises: client
normalization preserves well-formed claimedBy and drops malformed ones,
and the devices CLI formatter carries it through JSON data and renders
the text line (MCP shares the same serialization).
* docs: restructure AGENTS.md and CONTEXT.md for progressive disclosure
Apply the Claude 5 context-engineering guidance to the repo's agent docs:
keep the always-loaded file to gotchas and invariants, and move situational
guidance one hop away behind a routing table.
AGENTS.md 315 -> 229 lines. Cut generic agent-behavior boilerplate, three-way
duplication (Common Mistakes restated Hard Rules; Finding Source Owners
restated the registry section), and facts visible from the repo itself.
Kept verbatim: the expensive-lessons principles, enforcement gates, Hard
Rules, and environment traps.
Split out docs/agents/{cli-flags,pull-requests,device-verification}.md and
folded the Testing Matrix into docs/agents/testing.md, reframed around
pnpm check:affected so the prose stops duplicating the selector.
CONTEXT.md keeps all 50 terms, now grouped under a section index so a task
loads one section instead of the whole glossary.
* fix(check-affected): move the selector-owning sentinel to the Testing Matrix
The Testing Matrix moved from AGENTS.md to docs/agents/testing.md, but the
affected-check selector still treated only AGENTS.md as selector-owning. A
later matrix edit would have been classified as inert docs and skipped the
fail-open, so the selector could keep deriving gates from a spec that had
changed underneath it.
Move the sentinel with the prose, as a named SELECTOR_OWNING_DOCS set so the
next move is one line, and fix the two in-code comments plus the testing.md
paragraph that still pointed at the AGENTS.md matrix.
* docs: restore two rules dropped by the AGENTS.md split
Review caught two repo-specific rules that did not survive the move. Both are
prose without any backticked identifier, so the identifier-diff used to verify
the split could not see them.
- "Test through public interfaces; do not add unrelated production exports
solely to enable tests" returns next to the behavioral-tests rule in
docs/agents/testing.md, with the reason it exists.
- The guidance-ownership rule (decide whether new guidance/schema/metadata
belongs to the command surface, CLI grammar, CLI help, MCP projection, or
daemon runtime) returns to the always-loaded Docs & skills section, since it
governs all command-surface work and not just the flag case.
Also point the ADR routing row at docs/adr/README.md, which is already the
"read when you touch…" index, rather than at the bare directory.
