Ali Khokhar 3fba1c6fc3 Give messaging clear exact subtree semantics (#1072)
## Problem

Messaging `/clear` did not follow the selected platform message
boundary. Reply clears preserved the selected user prompt, while
standalone clears preserved user-authored messages and could reset FCC
state outside the invoking chat.

## Changes

| Before | After |
| --- | --- |
| Reply `/clear` removed a logical conversation branch but retained the
selected message. | Reply `/clear` deletes the selected message and its
literal reply subtree, including the clear command. |
| Standalone `/clear` retained user prompts and voice notes while
resetting global messaging state. | Standalone `/clear` deletes every
tracked message and resets FCC state only in the invoking platform and
chat. |
| Trees recorded only logical execution parentage. | Trees separately
persist logical execution ancestry and exact prompt/status reply
ownership. |
| Clear coordination used one global admission boundary. | Per-chat
clear generations coordinate admission, voice cancellation, persistence,
and best-effort platform deletion. |
| Persistence tracked only FCC-authored clearable output. | Persistence
tracks managed inbound and outbound messages and migrates legacy
entries. |

<details open><summary><h3>Greptile Summary</h3></summary>

This PR gives messaging `/clear` exact per-chat and reply-subtree
behavior. The main changes are:

- Per-chat clear generations for admission and startup-notice cleanup.
- Managed inbound and outbound message tracking for deletion.
- Exact prompt/status reply ownership in message trees.
- Scoped voice cancellation and clear persistence updates.
- Updated docs, smoke coverage, and messaging tests.
</details>

<h3>Confidence Score: 4/5</h3>

The clear flow is mostly well-contained, with one upgrade-path issue in
legacy tree restoration.

Newly created prompt/status subtrees use the new exact reference fields
consistently, and legacy snapshots can map old status replies to prompt
references. However, reply `/clear` on an upgraded status can miss
descendants and leave stale state/messages.

**What T-Rex did**
- T-Rex attempted to prepare and run a focused legacy snapshot
reproduction harness for legacy status replies detach, but tool access
was blocked before execution.
- A messaging clear smoke test harness was executed and reported a
passing result: 20 items collected and 20 passed in 1.69 seconds, with
traces for test\_reply\_clear\_uses\_literal and related paths shown in
the log.

Ali Khokhar 3081a72f41 Make application shutdown completion-driven (#1056)
## Problem\n\nShutdown could report success after bounded messaging
cleanup, hidden persistence failures, or failed managed-process stops.
An Admin restart could then construct a replacement while the old
runtime still owned work.\n\n## Changes\n\n| Before | After |\n| --- |
--- |\n| Runtime reused bounded interactive stop semantics for terminal
messaging cleanup. | Workflow close cancels work, stops managed
sessions, awaits every claim and recovery task, then flushes
persistence. |\n| Explicit persistence failures were logged and treated
as successful writes. | Explicit flushes and authoritative writes
propagate failure and stay dirty for retry; timer writes remain best
effort. |\n| Managed sessions and aliases were removed before subprocess
termination was confirmed. | Manager and session terminal states prevent
reuse, retain failed owners and PIDs, reject ID collisions, and retry
exact sessions. |\n| Admin restart followed the restart request even
after incomplete shutdown. | Supervisor restarts only when the prior
runtime reports its entire ownership graph closed. |\n| Partial
messaging startup cleanup could fail while application startup
continued. | Incomplete partial cleanup fails startup and retains the
exact graph for a later close attempt. |\n| Messaging task failures read
process-global settings. | Runtime injects diagnostic policy and the
messaging package depends only on core. |\n| Lifecycle edge cases were
verified only in isolated components. | Deterministic and live product
coverage proves composed retry, drain, privacy, and customer command
behavior. |

<details open><summary><h3>Greptile Summary</h3></summary>

This PR makes application shutdown wait for owned work to finish before
restart or exit. The main changes are:

- Runtime close now waits for messaging work, managed sessions, and
persistence flushes.
- Admin restart now requires the previous runtime to report full
closure.
- Managed Claude sessions now keep aliases and PIDs until stop is
confirmed.
- Session persistence now propagates explicit write failures and keeps
dirty state for retry.
- Messaging no longer reads global config from task-failure callbacks.

<h3>Confidence Score: 5/5</h3>

This looks safe to merge.

No blocking issues found in the changed code.

No files need attention.

When `_claim_finished_callback` raises a non-cancellation exception,
`_finish_and_continue` exits before `slot.transitioned` is set, before
the slot is removed from `_tasks`, and before `_idle` is set.
`MessagingWorkflow.close()` now waits on `wait_idle()`, so a finish-path

Ali Khokhar 2bcaf3ac74 Make messaging trees atomic ownership boundaries (#1048)
## Problem

Messaging tree state, queue coordination, task ownership, and
persistence were jointly mutated across several classes. Raw message IDs
were treated as globally unique, allowing cross-chat collisions and
unsafe cancellation or clear ordering.

## Changes

| Before | After |
| --- | --- |
| Managers and processors coordinated partial tree mutations through
exposed locks and mutable nodes. | MessageTree owns atomic transitions
and returns detached effects to task, UI, and persistence owners. |
| Raw message IDs and task identities could collide across chats or
detached generations. | Scoped tree identities and opaque claim IDs
isolate chats and reject stale task writes. |
| Session snapshots duplicated graph links and retained ingress
payloads. | Lean scoped snapshots rebuild validated indexes and continue
reading existing session files. |
| Stop, clear, and runner persistence could interleave across commit
boundaries. | Admission epochs, cancellation-safe detach, and
authoritative writes make committed cleanup durable. |
| Tree implementation classes leaked through messaging package exports.
| Adapter-facing values and ports remain supported while tree internals
stay internal. |

<!-- greptile_comment -->

Ali Khokhar 71a78a0c5a Move runtime packages under src namespace (#1029)
## Problem

Runtime modules were published as generic top-level packages like `api`,
`cli`, and `providers`. That shape is fragile for PyPI packaging and
weakens explicit ownership boundaries.

## Changes

| Before | After |
| --- | --- |
| Runtime code lived in root-level packages. | Runtime code lives under
`src/free_claude_code/`. |
| Console scripts targeted top-level modules. | Console scripts target
namespaced modules. |
| Tests and smoke helpers imported old package roots. | Tests and smoke
helpers import `free_claude_code.*`. |
| Packaging listed six root packages. | Packaging builds the single
namespaced package. |
| Contracts allowed old root package directories. | Contracts require
the src namespace and reject old root imports. |

<!-- greptile_comment -->

<details open><summary><h3>Greptile Summary</h3></summary>

This PR moves the runtime packages into the `src/free_claude_code`
namespace. The main changes are:

- Console scripts now point to `free_claude_code.*` entrypoints.
- Runtime imports, tests, and smoke helpers now use the namespaced
package.
- Packaging now builds the single `src/free_claude_code` package.
- Contract tests now reject old top-level runtime package roots and
imports.
</details>

<h3>Confidence Score: 5/5</h3>

This PR is safe to merge with minimal risk.

The changes are a broad but mostly mechanical namespace and
package-layout migration with updated packaging, tests, and contract
coverage.

No files require special attention.

**What T-Rex did**
- Reviewed the primary contract validation by examining the namespace
validation log, which documents the exact commands executed, the working
directory, exit codes, pytest output, wheel build output, install
output, and import/entrypoint resolution.
- Verified the wheel listing by inspecting the wheel listing artifact,
confirming the available wheel filenames for the namespace validation.
- Ran and inspected the isolated import/entrypoint validation harness
saved as package-installed-import-check.py to validate import resolution
and entrypoint exposure.
- Captured and noted the wheel filename record in
package-wheel-filename.txt to enable traceability of the observed
artifact.

Ali Khokhar 28e8996121 Make messaging cancellation terminal (#995)
## Problem

Messaging `/clear` and `/stop` could return before cancelled node tasks
finished cleanup. Late cleanup could save stale conversation state after
`/clear` reset FCC state.

## Changes

| Before | After |
| --- | --- |
| Tree cancellation called `task.cancel()` and returned immediately. |
Tree cancellation awaits cancelled task cleanup outside tree locks with
a bounded timeout. |
| Node runners saved snapshots even after their tree was removed or
replaced. | Node runners save only when their node still belongs to the
active tree queue. |
| `/clear` deletion stopped at a batch failure and left tracking vague.
| `/clear` attempts each tracked delete independently and clears
FCC-owned tracking state. |
| Architecture docs did not state terminal cancellation ownership. |
Architecture docs assign terminal cancellation to `messaging/trees` and
guarded cleanup persistence to node runners. |
| Package metadata stayed at `3.4.0`. | Package metadata and lockfile
move to `3.4.1`. |

<!-- greptile_comment -->

<details open><summary><h3>Greptile Summary</h3></summary>

This PR makes messaging cancellation wait for node cleanup before
command cleanup continues. The main changes are:

- Drains cancelled tree tasks with a bounded timeout outside tree locks.
- Guards node-runner snapshot saves so removed or replaced trees are not
restored by late cleanup.
- Changes `/clear` deletion to try each tracked platform message
independently.
- Removes cleared branch message IDs from FCC-owned tracking state.
- Adds cancellation, stale-save, and clear-delete regression tests.
- Bumps package metadata and lockfile version to `3.4.1`.
</details>

<h3>Confidence Score: 5/5</h3>

Safe to merge with minimal risk.

The cancellation paths now drain outside tree locks with a bounded wait,
stale snapshot persistence is guarded, and `/clear` continues through
individual delete failures. Tests cover the key cancellation cleanup,
timeout, stale-save, and clear-delete cases. No blocking correctness or
security issues were found in the changed files.

No files require special attention.

**What T-Rex did**
- Ran the messaging cancellation test suite with verbose output to
capture the command, current working directory, timestamps, and verbose
test names.
- Verified the targeted cancellation tests passed, including
test\_cancel\_tree\_waits\_for\_current\_task\_cleanup,
test\_cancel\_node\_waits\_for\_current\_task\_cleanup,
test\_cancel\_branch\_waits\_for\_current\_task\_cleanup,
test\_cancel\_all\_waits\_for\_current\_task\_cleanup\_across\_trees,
and test\_cancel\_task\_drain\_timeout\_is\_bounded.
- Verified that the coverage tests for /clear handling and stale
persistence guard also passed, including
test\_handle\_message\_clear\_command\_stops\_deletes\_and\_wipes\_state
and
test\_cancelled\_node\_runner\_does\_not\_save\_after\_clear\_replaces\_queue.
