feat(profiles): add /gentle:profiles clear and unreadable-record warning

[noxsystems]

Review size: this slice changes 71 code lines in extensions/gentle-ai.ts plus 135 test lines and 2 doc lines. GitHub's Files tab shows the cumulative diff with the chain until it merges; review only commits 3a5fdd00c and 3f8f9dc2b.

Summary

Part of #1064, slice 3b-i, PR 5d (clear action and unreadable-record warning). Builds on Enter wiring from #1992. With this PR, 3b-i covers the full persistence spec: bind, clear, invalid/future handling, lifecycle and affected-launch safety.

• /gentle:profiles clear (agreed in feat(profiles): support session-bound active profiles without global routing mutation #1064, no new shortcut): appends kind=clear and publishes only the returned state. New launches use the routing without a session profile (pins, repository declaration, global). The live orchestrator and every shared default are untouched.
• Cleared vs never-bound: a session that never selected a profile, or is already cleared, writes nothing and gets a notice saying so.
• Invalid or newer-version records: on start, resume, reload and tree navigation they raise a warning with the session file, the entry index and the line. Affected launches stay blocked (5b) until Enter or clear replaces the record, and clear reports that it cleared the unreadable record.
• Out of scope: footer/Status redesign and Usage. The panel and footer keep showing (session) only for a bound profile.

Changes

Commit	Change
3a5fdd00c	extensions/gentle-ai.ts (handleProfilesClear, notifySessionProfileProblem, command help text, start/tree hooks), tests/gentle-ai.test.ts, docs/readme-reference.md.
3f8f9dc2b	CodeRabbit follow-up: an unsaved or in-memory never-bound session reads as indeterminate; with no profile record on the branch, clear now writes nothing instead of a record that could never be corroborated and would block launches.

Test plan

Verified on top of #1992 (b951b3fd6), commit 3f8f9dc2b:

• 9 new tests through the registered /gentle:profiles command on a real persisted session: RED (clear opened the panel; no warning existed), GREEN after.
• tests/session-profile-*.test.ts + tests/gentle-ai.test.ts + tests/gentle-agents*.test.ts + tests/gentle-shell.test.ts: 850 pass, 0 fail.
• node scripts/check-types.mjs: 186 recorded diagnostics, no regressions.
• Native review (RDD): not run on this slice.

📝 Walkthrough

Walkthrough

Session profiles now persist as session records and restore from corroborated branch state. The extension adds clear handling, lifecycle synchronization, and authority checks before profile-dependent launches. New codecs, disk readers, append controllers, and tests cover persistence outcomes and fork behavior.

Changes

Session Profile Persistence and Lifecycle

Layer / File(s)	Summary
Profile format and disk corroboration lib/session-profile-persistence.ts, lib/session-profile-disk-reader.ts, docs/session-profile-format.md, tests/session-profile-persistence.test.ts, tests/session-profile-disk-reader*.test.ts	Adds v1 bind and clear records, branch replay, and disk corroboration. Tests cover record validation, branch selection, and inconsistent or unreadable session files.
Append authority and fork evidence lib/session-profile-append-controller.ts, tests/session-profile-append-controller*.test.ts	Adds append outcomes, refresh behavior, and fork handoff validation. Tests cover append failures, uncertain records, attachment changes, and copied branches.
Lifecycle and session authority lib/session-profile-integration.ts, lib/session-profile-authority.ts, tests/session-profile-integration.test.ts, tests/session-profile-authority.test.ts	Adds lifecycle attachment handling, queued selection coordination, and authority publication and reads. Tests cover session transitions, fork restoration, unavailable authority, and manager isolation.
Profile selection and launch gating extensions/gentle-ai.ts, extensions/gentle-agents.ts, lib/model-routing-authority.ts, tests/gentle-ai.test.ts, tests/gentle-agents.test.ts, tests/session-profile-extension.test.ts, docs/readme-reference.md	Profile selection and clear actions now use the session integration. Session events synchronize profile state, and agent operations require available authority. Tests cover selection, clear, navigation, and launch behavior.

Merge Risk: 🟡 Moderate · up to f2d67

Running /gentle:profiles clear in a session that never selected a profile and has no saved session file can write a clear record that cannot be confirmed. Subagent launches in that session are then blocked; for sessions that are never saved, the block lasts for the whole session. The clear command should treat that case as "nothing to clear" before this merges.

- Line 1632: Remove the redundant
requireSessionProfileAuthority(originalManager) call immediately following the
earlier synchronous authority check; preserve checks that run after awaits. In
the run flow, remove the early checks before buildRequest or pass their
validated binding into buildRequest so it can be reused without repeating the
check.

Review comments at @extensions/gentle-ai.ts:
- Around line 4933-4943: Update handleProfilesClear to check the active branch
for a gentle-pi.session-profile/ custom entry before treating an indeterminate
prior as a recoverable profile. If prior is indeterminate and no profile-family
entry exists, notify that nothing needs clearing and return without appending a
clear record; preserve existing absent and cleared behavior.
