Summary

  • pass()/fail() used ((var++)) which returns the pre-increment value — on first call (var=0) that trips set -e and the script exits after the first check. Switched to explicit $((var + 1)) assignment.
  • Error-log count piped journalctl through grep -c ., counting -- No entries -- as a match (false positive on clean systems). Now uses grep -vc '^-- ' to drop meta lines.

Fixes #302.

Test plan

  • Ran scripts/healthcheck.sh --version 0.35.1rc5 against live staging (post rc5 install) — 5 passed, 0 failed, exit 0.
  • Ran the no-errors path (clean logs, expected version match).
  • Confirm no regression for the FAIL paths — if staging ever emits an ERROR log within 60s of restart, the check should still flag it (logic unchanged apart from meta-line filtering).

* feat: add release guard hooks and document protection in CLAUDE.md

Defence-in-depth hooks prevent Claude Code from pushing to master,
merging PRs, creating tags, or triggering releases. Feature branch
pushes and PR creation remain allowed.

- release-guard.sh: Bash hook blocking master push, tags, releases, PR merge
- release-guard-protect.sh: Edit/Write hook protecting guard files and hooks.json
- release-guard-mcp.sh: GitHub MCP hook blocking merge and master writes
- hooks.json: register all three hooks
- CLAUDE.md: document release guard, update workflow roles, CI pipeline notes

* fix: clarify /config default labels and remove redundant "Works with" lines

Default labels now explain what "default" means for each setting:
- Diff preview: "default (off)" — matches actual behaviour (was "default (on)")
- Model/Reasoning: "default (engine decides)"
- API cost: "default (on)", Subscription usage: "default (off)"
- Plan mode home hint: "agent decides"
- Diff preview home hint: "buttons only"

Added info lines to plan mode and reasoning sub-pages explaining
the default behaviour in more detail.

Removed all 9 "Works with: ..." lines from sub-pages — they're
redundant because engine visibility guards already hide settings
from unsupported engines.

Fixes #119

* fix: suppress redundant cost footer on error runs

When a run fails (e.g. subscription limit hit), the diagnostic context
line from _extract_error() already shows cost, turns, and API time.
The 💰 cost footer was duplicating this same data in a different format.

Now the cost footer only appears on successful runs where it's the sole
source of cost information. Error runs still show cost in the diagnostic
line, and budget alerts still fire regardless.

Also adds usage field to mock Return dataclass (matching ErrorReturn)
so tests can verify cost footer behaviour on success runs.

* feat: suppress stall notifications when CPU-active + heartbeat re-render

When cpu_active=True (extended thinking, background agents), suppress
Telegram stall warning notifications and instead trigger a heartbeat
re-render so the elapsed time counter keeps ticking. Notifications
still fire when cpu_active=False or None (no baseline).

* docs: add iOS caption limitation note to file transfer guide

Telegram iOS doesn't show a caption field when sending documents via the
File picker, so /file put <path> captions aren't easily accessible.
Added a note with workarounds (use Desktop, send as photo, or let
auto-save handle it). Updated screenshot alt text to match actual
screenshot content.

* docs: swap 3rd hero screenshot for config-menu for visual variety

Replace plan-outline-approve (too similar to approval-diff-preview)
with config-menu showing the /config settings grid. The three hero

* feat: expand permission policies for Codex CLI and Gemini CLI in /config

Codex gets a new "Approval policy" page (full auto / safe) that passes
--ask-for-approval untrusted when safe mode is selected. Gemini's approval
mode expands from 2 to 3 tiers (read-only / edit files / full access) with
--approval-mode auto_edit for the middle tier. Both engines now show an
"Agent controls" section on the /config home page. Engine-specific model
default hints replace the generic "from CLI settings" text.

Also adds staging.sh helper, context-guard-stop hook, and docs updates.

Closes #131

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: /config UX overhaul, resume line toggle, cost budget settings, model metadata

/config UX cleanup:
- Convert all binary toggles from 3-column (on/off/clear) to 2-column
  (toggle + clear) for better mobile tap targets
- Merge Engine + Model into combined "Engine & model" page
- Reorganise home page to max 2 buttons per row across all engines
- Split plan mode 3-option rows (off/on/auto) into 2+1 layout
- Add _toggle_row() helper for consistent toggle button rendering

New features:
- #128: Resume line /config toggle — per-chat show_resume_line override
  via EngineOverrides with On/Off/Clear buttons, wired into executor
- #129: Cost budget /config settings — per-chat budget_enabled and
  budget_auto_cancel overrides on the Cost & Usage page, wired into
  _check_cost_budget() in runner_bridge.py

Model metadata improvements:
- Show Claude Code [1m] context window suffix: "opus 4.6 (1M)"
- Strip Gemini CLI "auto-" prefix: "auto-gemini-3" → "gemini-3"
- Future-proof: unknown suffixes default to .upper() (e.g. [500k] → 500K)

Bug fixes:
- #124: Standalone override commands (/planmode, /model, /reasoning) now
  preserve all EngineOverrides fields including new ones
- Error handling: control_response.write_failed catch-all in claude.py,
  ask_question.extraction_failed warning, model.override.failed logging

Hardening:
- Plan outline sent as separate ephemeral message (avoids 4096 char truncation)
- Added show_resume_line, budget_enabled, budget_auto_cancel to
  EngineOverrides, EngineRunOptions, normalize/merge, and all constructors

Tests: 1610 passed, 80.56% coverage, ruff clean.
Integration tested on @untether_dev_bot across all 6 engine chats.

Closes #128, closes #129, fixes #124

* feat: /continue command — cross-environment resume for all engines (#135)

New `/continue` command resumes the most recent CLI session in the
project directory from Telegram. Enables starting a session in your
terminal and picking it up from your phone.

Engine support: Claude (--continue), Codex (resume --last), OpenCode
(--continue), Pi (--continue), Gemini (--resume latest). AMP not
supported (requires explicit thread ID).

Includes ResumeToken.is_continue flag, build_args for all 6 runners,
reserved command registration, resume emoji prefix stripping for
reply-to-continue, docs (how-to guide, README, commands ref, routing
explanation, conversation modes tutorial), and 99 new test assertions.

Integration tested against @untether_dev_bot — all 5 supported engines
passed secret-recall verification via Telegram MCP.

* feat: agent outbox file delivery + fix cross-chat ask stealing (#143, #144)

Outbox delivery (#143): agents write files to .untether-outbox/ during a
run; Untether sends them as Telegram documents on completion with 📎
captions. Config: outbox_enabled, outbox_dir, outbox_max_files,
outbox_cleanup. Deny-glob security, size limits, auto-cleanup.
Preamble updated for all 6 engines. Integration tested across
Claude, Codex, OpenCode, Pi, and Gemini.

AskUserQuestion fix (#144): _PENDING_ASK_REQUESTS and
_ASK_QUESTION_FLOWS were global dicts with no chat_id scoping — a
pending ask in one chat would steal the next message from any other
chat. Added channel_id contextvar and scoped all ask lookups by it.
Session cleanup now also clears stale pending asks.

- Reduce Telegram API timeout from 120s to 30s (#145)
- OpenCode error runs show error text instead of empty body (#146)
- Pi /continue captures session ID via allow_id_promotion (#147)
- Post-outline approval uses skip_reply to avoid "not found" (#148)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: post-outline notification reply + OpenCode empty body (#148, #150)

- #148: skip_reply callback results now bypass the executor's default
  reply_to fallback, sending directly via the transport with no
  reply_to_message_id. Previously, the executor treated reply_to=None
  as "use default" which pointed to the (deleted) outline message.

- #150: OpenCode normal completion with no Text events now falls back
  to last_tool_error. Added state.last_tool_error field populated on
  ToolUse error status. Covers both translate() and stream_end_events().

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: suppress post-outline notification to avoid "message not found" (#148)

After outline approval/denial, the progress loop's _send_notify was
firing for the next tool approval, but the notification's reply_to
anchor could reference deleted state. Added _outline_just_resolved
flag to skip one notification cycle after outline cleanup.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: note OpenCode lacks auto-compaction — long sessions degrade (#150)

Added known limitation to OpenCode runner docs and integration testing
playbook. OpenCode sessions accumulate unbounded context (no compaction
events unlike Pi). Workaround: use /new before isolated tests.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: skip_reply on regular approve path when outline was deleted (#148)

The "Approve Plan" button on outline messages uses the real
ExitPlanMode request_id, routing through the regular approve path
(not the da: synthetic path). When outline messages exist, set
skip_reply=True on the CommandResult to avoid replying to the
just-deleted outline message.

Also added reply_to_message_id and text_preview to transport.send.failed
warning for easier debugging.

* fix: resolve /config "default" labels to effective on/off values (#152)

Sub-pages showed "Current: default" or "default (on/off)" while buttons
already showed the resolved value. Now all boolean-toggle settings show
the effective on/off value in both text and buttons.

Affected: verbose, ask mode, diff preview, API cost, subscription usage,
budget enabled/auto-cancel, resume line. Home page cost & resume labels
also resolved.

Plan mode, model, and reasoning keep "default" since they depend on CLI
settings and aren't simple on/off booleans.

* fix: broaden frozen ring buffer stall escalation beyond MCP tools (#155)

Frozen ring buffer escalation was gated on `mcp_server is not None`,
so general stalls with cpu_active=True and no MCP tool running were
silently suppressed indefinitely. Broadened to fire for all stalls
after 3+ checks with no new JSONL events regardless of tool type.

New notification: "CPU active, no new events" for non-MCP frozen stalls.

* fix: tool approval buttons no longer suppressed after outline approval (#156)

After "Approve Plan" on an outline, the stale discuss_approve action
remained in ProgressTracker with completed=False. The renderer picked
up its stale "Approve Plan"/"Deny" buttons first, then the suppression
logic at line 994 stripped ALL buttons — including new Write/Edit/Bash
approval buttons. Claude blocked indefinitely waiting for approval.

Fix: after suppressing stale buttons, complete the discuss_approve
action(s) in the tracker, reset _outline_sent, and trigger a re-render
so subsequent tool requests get their own Approve/Deny buttons.

* feat: migrate to dev branch workflow — dev→TestPyPI, master→PyPI

Branch model:
- feature/* → PR → dev (TestPyPI auto-publish) → PR → master (PyPI)
- master always matches latest PyPI release
- dev is the integration/staging branch

CI changes:
- ci.yml: TestPyPI publish triggers on dev push (was master)
- ci.yml, codeql.yml: CI runs on both master and dev pushes
- dependabot.yml: PRs target dev branch

Hook changes:
- release-guard.sh: updated messages to mention dev branch
- release-guard-mcp.sh: updated messages to mention dev branch
- Both hooks already allow dev pushes (only block master/main)

Documentation:
- CLAUDE.md: updated 3-phase workflow, CI table, release guard docs
- dev-workflow.md: added branch model section
- release-discipline.md: added dev branch staging notes

* ci: retrigger CI for PR #160

* feat: allow Claude Code to merge PRs targeting dev branch only

Release guard hooks now check the PR's base branch:
- dev → allowed (TestPyPI/staging)
- master/main → blocked (PyPI releases remain Nathan-only)

Both Bash hook (gh pr merge) and MCP hook (merge_pull_request)
updated with base branch checking via gh pr view.

* fix: clarify /config default labels and remove redundant "Works with" lines

Default labels now explain what "default" means for each setting:
- Diff preview: "default (off)" — matches actual behaviour (was "default (on)")
- Model/Reasoning: "default (engine decides)"
- API cost: "default (on)", Subscription usage: "default (off)"
- Plan mode home hint: "agent decides"
- Diff preview home hint: "buttons only"

Added info lines to plan mode and reasoning sub-pages explaining
the default behaviour in more detail.

Removed all 9 "Works with: ..." lines from sub-pages — they're
redundant because engine visibility guards already hide settings
from unsupported engines.

Fixes #119

* fix: suppress redundant cost footer on error runs

When a run fails (e.g. subscription limit hit), the diagnostic context
line from _extract_error() already shows cost, turns, and API time.
The 💰 cost footer was duplicating this same data in a different format.

Now the cost footer only appears on successful runs where it's the sole
source of cost information. Error runs still show cost in the diagnostic
line, and budget alerts still fire regardless.

Also adds usage field to mock Return dataclass (matching ErrorReturn)
so tests can verify cost footer behaviour on success runs.

* feat: suppress stall notifications when CPU-active + heartbeat re-render

When cpu_active=True (extended thinking, background agents), suppress
Telegram stall warning notifications and instead trigger a heartbeat
re-render so the elapsed time counter keeps ticking. Notifications
still fire when cpu_active=False or None (no baseline).

Telegram iOS doesn't show a caption field when sending documents via the

* feat: expand permission policies for Codex CLI and Gemini CLI in /config

Codex gets a new "Approval policy" page (full auto / safe) that passes
--ask-for-approval untrusted when safe mode is selected. Gemini's approval
mode expands from 2 to 3 tiers (read-only / edit files / full access) with
--approval-mode auto_edit for the middle tier. Both engines now show an
"Agent controls" section on the /config home page. Engine-specific model
default hints replace the generic "from CLI settings" text.

Also adds staging.sh helper, context-guard-stop hook, and docs updates.

Closes #131

* feat: /config UX overhaul, resume line toggle, cost budget settings, model metadata

/config UX cleanup:
- Convert all binary toggles from 3-column (on/off/clear) to 2-column
  (toggle + clear) for better mobile tap targets
- Merge Engine + Model into combined "Engine & model" page
- Reorganise home page to max 2 buttons per row across all engines
- Split plan mode 3-option rows (off/on/auto) into 2+1 layout
- Add _toggle_row() helper for consistent toggle button rendering

New features:
- #128: Resume line /config toggle — per-chat show_resume_line override
  via EngineOverrides with On/Off/Clear buttons, wired into executor
- #129: Cost budget /config settings — per-chat budget_enabled and
  budget_auto_cancel overrides on the Cost & Usage page, wired into
  _check_cost_budget() in runner_bridge.py

Model metadata improvements:
- Show Claude Code [1m] context window suffix: "opus 4.6 (1M)"
- Strip Gemini CLI "auto-" prefix: "auto-gemini-3" → "gemini-3"
- Future-proof: unknown suffixes default to .upper() (e.g. [500k] → 500K)

Bug fixes:
- #124: Standalone override commands (/planmode, /model, /reasoning) now
  preserve all EngineOverrides fields including new ones
- Error handling: control_response.write_failed catch-all in claude.py,
  ask_question.extraction_failed warning, model.override.failed logging

Hardening:
- Plan outline sent as separate ephemeral message (avoids 4096 char truncation)
- Added show_resume_line, budget_enabled, budget_auto_cancel to
  EngineOverrides, EngineRunOptions, normalize/merge, and all constructors

Tests: 1610 passed, 80.56% coverage, ruff clean.
Integration tested on @untether_dev_bot across all 6 engine chats.

* feat: /continue command — cross-environment resume for all engines (#135)

New `/continue` command resumes the most recent CLI session in the
project directory from Telegram. Enables starting a session in your
terminal and picking it up from your phone.

Engine support: Claude (--continue), Codex (resume --last), OpenCode
(--continue), Pi (--continue), Gemini (--resume latest). AMP not
supported (requires explicit thread ID).

Includes ResumeToken.is_continue flag, build_args for all 6 runners,
reserved command registration, resume emoji prefix stripping for
reply-to-continue, docs (how-to guide, README, commands ref, routing
explanation, conversation modes tutorial), and 99 new test assertions.

Integration tested against @untether_dev_bot — all 5 supported engines
passed secret-recall verification via Telegram MCP.

* feat: agent outbox file delivery + fix cross-chat ask stealing (#143, #144)

Outbox delivery (#143): agents write files to .untether-outbox/ during a
run; Untether sends them as Telegram documents on completion with 📎
captions. Config: outbox_enabled, outbox_dir, outbox_max_files,
outbox_cleanup. Deny-glob security, size limits, auto-cleanup.
Preamble updated for all 6 engines. Integration tested across
Claude, Codex, OpenCode, Pi, and Gemini.

AskUserQuestion fix (#144): _PENDING_ASK_REQUESTS and
_ASK_QUESTION_FLOWS were global dicts with no chat_id scoping — a
pending ask in one chat would steal the next message from any other
chat. Added channel_id contextvar and scoped all ask lookups by it.
Session cleanup now also clears stale pending asks.

- #148: skip_reply callback results now bypass the executor's default
  reply_to fallback, sending directly via the transport with no
  reply_to_message_id. Previously, the executor treated reply_to=None
  as "use default" which pointed to the (deleted) outline message.

- #150: OpenCode normal completion with no Text events now falls back
  to last_tool_error. Added state.last_tool_error field populated on
  ToolUse error status. Covers both translate() and stream_end_events().

* fix: suppress post-outline notification to avoid "message not found" (#148)

After outline approval/denial, the progress loop's _send_notify was

* fix: skip_reply on regular approve path when outline was deleted (#148)

The "Approve Plan" button on outline messages uses the real
ExitPlanMode request_id, routing through the regular approve path
(not the da: synthetic path). When outline messages exist, set
skip_reply=True on the CommandResult to avoid replying to the
just-deleted outline message.

Also added reply_to_message_id and text_preview to transport.send.failed
warning for easier debugging.

Sub-pages showed "Current: default" or "default (on/off)" while buttons
already showed the resolved value. Now all boolean-toggle settings show

Affected: verbose, ask mode, diff preview, API cost, subscription usage,
budget enabled/auto-cancel, resume line. Home page cost & resume labels
also resolved.

Plan mode, model, and reasoning keep "default" since they depend on CLI
settings and aren't simple on/off booleans.

* fix: broaden frozen ring buffer stall escalation beyond MCP tools (#155)

Frozen ring buffer escalation was gated on `mcp_server is not None`,
so general stalls with cpu_active=True and no MCP tool running were
silently suppressed indefinitely. Broadened to fire for all stalls
after 3+ checks with no new JSONL events regardless of tool type.

New notification: "CPU active, no new events" for non-MCP frozen stalls.

* fix: tool approval buttons no longer suppressed after outline approval (#156)

After "Approve Plan" on an outline, the stale discuss_approve action
remained in ProgressTracker with completed=False. The renderer picked
up its stale "Approve Plan"/"Deny" buttons first, then the suppression
logic at line 994 stripped ALL buttons — including new Write/Edit/Bash
approval buttons. Claude blocked indefinitely waiting for approval.

Fix: after suppressing stale buttons, complete the discuss_approve
action(s) in the tracker, reset _outline_sent, and trigger a re-render
so subsequent tool requests get their own Approve/Deny buttons.

- ci.yml: TestPyPI publish triggers on dev push (was master)
- ci.yml, codeql.yml: CI runs on both master and dev pushes
- dependabot.yml: PRs target dev branch

Hook changes:
- release-guard.sh: updated messages to mention dev branch
- release-guard-mcp.sh: updated messages to mention dev branch
- Both hooks already allow dev pushes (only block master/main)

Documentation:
- CLAUDE.md: updated 3-phase workflow, CI table, release guard docs
- dev-workflow.md: added branch model section
- release-discipline.md: added dev branch staging notes

* ci: retrigger CI for PR #160

* feat: allow Claude Code to merge PRs targeting dev branch only

* fix: clarify /config default labels and remove redundant "Works with" lines

Default labels now explain what "default" means for each setting:
- Diff preview: "default (off)" — matches actual behaviour (was "default (on)")
- Model/Reasoning: "default (engine decides)"
- API cost: "default (on)", Subscription usage: "default (off)"
- Plan mode home hint: "agent decides"
- Diff preview home hint: "buttons only"

Added info lines to plan mode and reasoning sub-pages explaining
the default behaviour in more detail.

Removed all 9 "Works with: ..." lines from sub-pages — they're
redundant because engine visibility guards already hide settings
from unsupported engines.

Fixes #119

* fix: suppress redundant cost footer on error runs

When a run fails (e.g. subscription limit hit), the diagnostic context
line from _extract_error() already shows cost, turns, and API time.
The 💰 cost footer was duplicating this same data in a different format.

Now the cost footer only appears on successful runs where it's the sole
source of cost information. Error runs still show cost in the diagnostic
line, and budget alerts still fire regardless.

Also adds usage field to mock Return dataclass (matching ErrorReturn)
so tests can verify cost footer behaviour on success runs.

sys.stdin.buffer.read() and open(...,'rb').read(). First
triggered when PR #122 changed the version (rc1 → rc2).

* docs: add iOS caption limitation note to file transfer guide

Telegram iOS doesn't show a caption field when sending documents via the
File picker, so /file put <path> captions aren't easily accessible.
Added a note with workarounds (use Desktop, send as photo, or let
auto-save handle it). Updated screenshot alt text to match actual
screenshot content.

* feat: expand permission policies for Codex CLI and Gemini CLI in /config

Codex gets a new "Approval policy" page (full auto / safe) that passes
--ask-for-approval untrusted when safe mode is selected. Gemini's approval
mode expands from 2 to 3 tiers (read-only / edit files / full access) with
--approval-mode auto_edit for the middle tier. Both engines now show an
"Agent controls" section on the /config home page. Engine-specific model
default hints replace the generic "from CLI settings" text.

Also adds staging.sh helper, context-guard-stop hook, and docs updates.

Closes #131

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: /config UX overhaul, resume line toggle, cost budget settings, model metadata

/config UX cleanup:
- Convert all binary toggles from 3-column (on/off/clear) to 2-column
  (toggle + clear) for better mobile tap targets
- Merge Engine + Model into combined "Engine & model" page
- Reorganise home page to max 2 buttons per row across all engines
- Split plan mode 3-option rows (off/on/auto) into 2+1 layout
- Add _toggle_row() helper for consistent toggle button rendering

New features:
- #128: Resume line /config toggle — per-chat show_resume_line override
  via EngineOverrides with On/Off/Clear buttons, wired into executor
- #129: Cost budget /config settings — per-chat budget_enabled and
  budget_auto_cancel overrides on the Cost & Usage page, wired into
  _check_cost_budget() in runner_bridge.py

Model metadata improvements:
- Show Claude Code [1m] context window suffix: "opus 4.6 (1M)"
- Strip Gemini CLI "auto-" prefix: "auto-gemini-3" → "gemini-3"
- Future-proof: unknown suffixes default to .upper() (e.g. [500k] → 500K)

Bug fixes:
- #124: Standalone override commands (/planmode, /model, /reasoning) now
  preserve all EngineOverrides fields including new ones
- Error handling: control_response.write_failed catch-all in claude.py,
  ask_question.extraction_failed warning, model.override.failed logging

Hardening:
- Plan outline sent as separate ephemeral message (avoids 4096 char truncation)
- Added show_resume_line, budget_enabled, budget_auto_cancel to
  EngineOverrides, EngineRunOptions, normalize/merge, and all constructors

Tests: 1610 passed, 80.56% coverage, ruff clean.
Integration tested on @untether_dev_bot across all 6 engine chats.

* feat: /continue command — cross-environment resume for all engines (#135)

New `/continue` command resumes the most recent CLI session in the
project directory from Telegram. Enables starting a session in your
terminal and picking it up from your phone.

Engine support: Claude (--continue), Codex (resume --last), OpenCode
(--continue), Pi (--continue), Gemini (--resume latest). AMP not
supported (requires explicit thread ID).

Includes ResumeToken.is_continue flag, build_args for all 6 runners,
reserved command registration, resume emoji prefix stripping for
reply-to-continue, docs (how-to guide, README, commands ref, routing
explanation, conversation modes tutorial), and 99 new test assertions.

Integration tested against @untether_dev_bot — all 5 supported engines
passed secret-recall verification via Telegram MCP.

* feat: agent outbox file delivery + fix cross-chat ask stealing (#143, #144)

Outbox delivery (#143): agents write files to .untether-outbox/ during a
run; Untether sends them as Telegram documents on completion with 📎
captions. Config: outbox_enabled, outbox_dir, outbox_max_files,
outbox_cleanup. Deny-glob security, size limits, auto-cleanup.
Preamble updated for all 6 engines. Integration tested across
Claude, Codex, OpenCode, Pi, and Gemini.

AskUserQuestion fix (#144): _PENDING_ASK_REQUESTS and
_ASK_QUESTION_FLOWS were global dicts with no chat_id scoping — a
pending ask in one chat would steal the next message from any other
chat. Added channel_id contextvar and scoped all ask lookups by it.
Session cleanup now also clears stale pending asks.

* fix: post-outline notification reply + OpenCode empty body (#148, #150)

- #148: skip_reply callback results now bypass the executor's default
  reply_to fallback, sending directly via the transport with no
  reply_to_message_id. Previously, the executor treated reply_to=None
  as "use default" which pointed to the (deleted) outline message.

- #150: OpenCode normal completion with no Text events now falls back
  to last_tool_error. Added state.last_tool_error field populated on
  ToolUse error status. Covers both translate() and stream_end_events().

* fix: suppress post-outline notification to avoid "message not found" (#148)

After outline approval/denial, the progress loop's _send_notify was
firing for the next tool approval, but the notification's reply_to
anchor could reference deleted state. Added _outline_just_resolved
flag to skip one notification cycle after outline cleanup.

* docs: note OpenCode lacks auto-compaction — long sessions degrade (#150)

* fix: skip_reply on regular approve path when outline was deleted (#148)

The "Approve Plan" button on outline messages uses the real
ExitPlanMode request_id, routing through the regular approve path
(not the da: synthetic path). When outline messages exist, set
skip_reply=True on the CommandResult to avoid replying to the
just-deleted outline message.

Also added reply_to_message_id and text_preview to transport.send.failed
warning for easier debugging.

Sub-pages showed "Current: default" or "default (on/off)" while buttons
already showed the resolved value. Now all boolean-toggle settings show

Affected: verbose, ask mode, diff preview, API cost, subscription usage,
budget enabled/auto-cancel, resume line. Home page cost & resume labels
also resolved.

Plan mode, model, and reasoning keep "default" since they depend on CLI
settings and aren't simple on/off booleans.

* fix: broaden frozen ring buffer stall escalation beyond MCP tools (#155)

Frozen ring buffer escalation was gated on `mcp_server is not None`,
so general stalls with cpu_active=True and no MCP tool running were
silently suppressed indefinitely. Broadened to fire for all stalls
after 3+ checks with no new JSONL events regardless of tool type.

New notification: "CPU active, no new events" for non-MCP frozen stalls.

* fix: tool approval buttons no longer suppressed after outline approval (#156)

After "Approve Plan" on an outline, the stale discuss_approve action
remained in ProgressTracker with completed=False. The renderer picked
up its stale "Approve Plan"/"Deny" buttons first, then the suppression
logic at line 994 stripped ALL buttons — including new Write/Edit/Bash
approval buttons. Claude blocked indefinitely waiting for approval.

Fix: after suppressing stale buttons, complete the discuss_approve
action(s) in the tracker, reset _outline_sent, and trigger a re-render
so subsequent tool requests get their own Approve/Deny buttons.

* feat: migrate to dev branch workflow — dev→TestPyPI, master→PyPI

Branch model:
- feature/* → PR → dev (TestPyPI auto-publish) → PR → master (PyPI)
- master always matches latest PyPI release
- dev is the integration/staging branch

CI changes:
- ci.yml: TestPyPI publish triggers on dev push (was master)
- ci.yml, codeql.yml: CI runs on both master and dev pushes
- dependabot.yml: PRs target dev branch

Hook changes:
- release-guard.sh: updated messages to mention dev branch
- release-guard-mcp.sh: updated messages to mention dev branch
- Both hooks already allow dev pushes (only block master/main)

Documentation:
- CLAUDE.md: updated 3-phase workflow, CI table, release guard docs
- dev-workflow.md: added branch model section
- release-discipline.md: added dev branch staging notes

* ci: retrigger CI for PR #160

* feat: allow Claude Code to merge PRs targeting dev branch only

Release guard hooks now check the PR's base branch:
- dev → allowed (TestPyPI/staging)
- master/main → blocked (PyPI releases remain Nathan-only)

Both Bash hook (gh pr merge) and MCP hook (merge_pull_request)
updated with base branch checking via gh pr view.

* docs: add workflow mode indicator and modes.md to CLAUDE.md

  ExitPlanMode requests work correctly (#163)
- Sanitise text_link entities with invalid URLs (localhost, loopback,
  file paths, bare hostnames) by converting to code entities — prevents
  silent 400 errors that drop the entire final message (#157)
- Merge v0.34.5 changelog into v0.35.0 — v0.34.5 was never released
  (latest PyPI is v0.34.4), all rc1-rc7 work is v0.35.0

  despite cpu_active=True)
- _has_running_mcp_tool() for MCP server name extraction
- _STALL_THRESHOLD_MCP_TOOL (15 min, configurable via watchdog)
- MCP-aware notification text ("MCP tool may be hung", "CPU active,
  no new events", "MCP tool running")
- 8 new tests + 2 updated existing tests
- mcp_tool_timeout watchdog setting

* fix: clarify /config default labels and remove redundant "Works with" lines

Default labels now explain what "default" means for each setting:
- Diff preview: "default (off)" — matches actual behaviour (was "default (on)")
- Model/Reasoning: "default (engine decides)"
- API cost: "default (on)", Subscription usage: "default (off)"
- Plan mode home hint: "agent decides"
- Diff preview home hint: "buttons only"

Added info lines to plan mode and reasoning sub-pages explaining
the default behaviour in more detail.

Removed all 9 "Works with: ..." lines from sub-pages — they're
redundant because engine visibility guards already hide settings
from unsupported engines.

Fixes #119

* fix: suppress redundant cost footer on error runs

When a run fails (e.g. subscription limit hit), the diagnostic context
line from _extract_error() already shows cost, turns, and API time.
The 💰 cost footer was duplicating this same data in a different format.

Now the cost footer only appears on successful runs where it's the sole
source of cost information. Error runs still show cost in the diagnostic
line, and budget alerts still fire regardless.

Also adds usage field to mock Return dataclass (matching ErrorReturn)
so tests can verify cost footer behaviour on success runs.

sys.stdin.buffer.read() and open(...,'rb').read(). First
triggered when PR #122 changed the version (rc1 → rc2).

* docs: convert markdown images to HTML img tags for GitHub compatibility

Switch from MkDocs `![alt](src){ loading=lazy }` syntax to HTML `<img>`

images with no width constraint.

* docs: add iOS caption limitation note to file transfer guide

Telegram iOS doesn't show a caption field when sending documents via the
File picker, so /file put <path> captions aren't easily accessible.
Added a note with workarounds (use Desktop, send as photo, or let
auto-save handle it). Updated screenshot alt text to match actual
screenshot content.

* feat: expand permission policies for Codex CLI and Gemini CLI in /config

Codex gets a new "Approval policy" page (full auto / safe) that passes
--ask-for-approval untrusted when safe mode is selected. Gemini's approval
mode expands from 2 to 3 tiers (read-only / edit files / full access) with
--approval-mode auto_edit for the middle tier. Both engines now show an
"Agent controls" section on the /config home page. Engine-specific model
default hints replace the generic "from CLI settings" text.

Also adds staging.sh helper, context-guard-stop hook, and docs updates.

Closes #131

* chore: staging 0.34.5rc4

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: /config UX overhaul, resume line toggle, cost budget settings, model metadata

/config UX cleanup:
- Convert all binary toggles from 3-column (on/off/clear) to 2-column
  (toggle + clear) for better mobile tap targets
- Merge Engine + Model into combined "Engine & model" page
- Reorganise home page to max 2 buttons per row across all engines
- Split plan mode 3-option rows (off/on/auto) into 2+1 layout
- Add _toggle_row() helper for consistent toggle button rendering

New features:
- #128: Resume line /config toggle — per-chat show_resume_line override
  via EngineOverrides with On/Off/Clear buttons, wired into executor
- #129: Cost budget /config settings — per-chat budget_enabled and
  budget_auto_cancel overrides on the Cost & Usage page, wired into
  _check_cost_budget() in runner_bridge.py

Model metadata improvements:
- Show Claude Code [1m] context window suffix: "opus 4.6 (1M)"
- Strip Gemini CLI "auto-" prefix: "auto-gemini-3" → "gemini-3"
- Future-proof: unknown suffixes default to .upper() (e.g. [500k] → 500K)

Bug fixes:
- #124: Standalone override commands (/planmode, /model, /reasoning) now
  preserve all EngineOverrides fields including new ones
- Error handling: control_response.write_failed catch-all in claude.py,
  ask_question.extraction_failed warning, model.override.failed logging

Hardening:
- Plan outline sent as separate ephemeral message (avoids 4096 char truncation)
- Added show_resume_line, budget_enabled, budget_auto_cancel to
  EngineOverrides, EngineRunOptions, normalize/merge, and all constructors

Tests: 1610 passed, 80.56% coverage, ruff clean.
Integration tested on @untether_dev_bot across all 6 engine chats.

Closes #128, closes #129, fixes #124

* feat: /continue command — cross-environment resume for all engines (#135)

New `/continue` command resumes the most recent CLI session in the
project directory from Telegram. Enables starting a session in your
terminal and picking it up from your phone.

Engine support: Claude (--continue), Codex (resume --last), OpenCode
(--continue), Pi (--continue), Gemini (--resume latest). AMP not
supported (requires explicit thread ID).

Includes ResumeToken.is_continue flag, build_args for all 6 runners,
reserved command registration, resume emoji prefix stripping for
reply-to-continue, docs (how-to guide, README, commands ref, routing
explanation, conversation modes tutorial), and 99 new test assertions.

Integration tested against @untether_dev_bot — all 5 supported engines
passed secret-recall verification via Telegram MCP.

* feat: agent outbox file delivery + fix cross-chat ask stealing (#143, #144)

Outbox delivery (#143): agents write files to .untether-outbox/ during a
run; Untether sends them as Telegram documents on completion with 📎
captions. Config: outbox_enabled, outbox_dir, outbox_max_files,
outbox_cleanup. Deny-glob security, size limits, auto-cleanup.
Preamble updated for all 6 engines. Integration tested across
Claude, Codex, OpenCode, Pi, and Gemini.

AskUserQuestion fix (#144): _PENDING_ASK_REQUESTS and
_ASK_QUESTION_FLOWS were global dicts with no chat_id scoping — a
pending ask in one chat would steal the next message from any other
chat. Added channel_id contextvar and scoped all ask lookups by it.
Session cleanup now also clears stale pending asks.

- Reduce Telegram API timeout from 120s to 30s (#145)
- OpenCode error runs show error text instead of empty body (#146)
- Pi /continue captures session ID via allow_id_promotion (#147)

* fix: post-outline notification reply + OpenCode empty body (#148, #150)

- #148: skip_reply callback results now bypass the executor's default
  reply_to fallback, sending directly via the transport with no
  reply_to_message_id. Previously, the executor treated reply_to=None
  as "use default" which pointed to the (deleted) outline message.

- #150: OpenCode normal completion with no Text events now falls back
  to last_tool_error. Added state.last_tool_error field populated on
  ToolUse error status. Covers both translate() and stream_end_events().

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: suppress post-outline notification to avoid "message not found" (#148)

After outline approval/denial, the progress loop's _send_notify was
firing for the next tool approval, but the notification's reply_to
anchor could reference deleted state. Added _outline_just_resolved
flag to skip one notification cycle after outline cleanup.

* docs: note OpenCode lacks auto-compaction — long sessions degrade (#150)

Added known limitation to OpenCode runner docs and integration testing

* fix: skip_reply on regular approve path when outline was deleted (#148)

The "Approve Plan" button on outline messages uses the real
ExitPlanMode request_id, routing through the regular approve path
(not the da: synthetic path). When outline messages exist, set
skip_reply=True on the CommandResult to avoid replying to the
just-deleted outline message.

Also added reply_to_message_id and text_preview to transport.send.failed
warning for easier debugging.

* fix: resolve /config "default" labels to effective on/off values (#152)

Sub-pages showed "Current: default" or "default (on/off)" while buttons
already showed the resolved value. Now all boolean-toggle settings show
the effective on/off value in both text and buttons.

Affected: verbose, ask mode, diff preview, API cost, subscription usage,
budget enabled/auto-cancel, resume line. Home page cost & resume labels
also resolved.

Plan mode, model, and reasoning keep "default" since they depend on CLI
settings and aren't simple on/off booleans.

* fix: broaden frozen ring buffer stall escalation beyond MCP tools (#155)

Frozen ring buffer escalation was gated on `mcp_server is not None`,
so general stalls with cpu_active=True and no MCP tool running were
silently suppressed indefinitely. Broadened to fire for all stalls
after 3+ checks with no new JSONL events regardless of tool type.

New notification: "CPU active, no new events" for non-MCP frozen stalls.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: tool approval buttons no longer suppressed after outline approval (#156)

After "Approve Plan" on an outline, the stale discuss_approve action
remained in ProgressTracker with completed=False. The renderer picked
up its stale "Approve Plan"/"Deny" buttons first, then the suppression
logic at line 994 stripped ALL buttons — including new Write/Edit/Bash
approval buttons. Claude blocked indefinitely waiting for approval.

Fix: after suppressing stale buttons, complete the discuss_approve
action(s) in the tracker, reset _outline_sent, and trigger a re-render
so subsequent tool requests get their own Approve/Deny buttons.

- Derived from session_mode + topics.enabled config values
- _resolve_mode_label() helper in backend.py

Bug fixes:
- Fix UnboundLocalError crash when topics validation fails on startup (#158)
  - Moved import signal and shutdown imports before try block in loop.py
- Downgrade can_manage_topics check from fatal error to warning (#159)
  - Bot can now start without manage_topics admin right
  - Existing topics work fine; only topic creation/editing affected

Tests:
- 17 new unit tests for stateless/handoff mode (test_stateless_mode.py)
  - _should_show_resume_line, _chat_session_key, ResumeResolver, ResumeLineProxy
  - Integration-level: stateless shows resume lines, no auto-resume, chat hides lines
- 3 new tests for mode indicator in startup message (test_telegram_backend.py)

Docs:
- New docs/reference/modes.md — comprehensive reference for all 3 workflow modes
- Updated docs/reference/index.md and zensical.toml nav with modes page

* docs: comprehensive three-mode coverage across all documentation

New:

* feat: migrate to dev branch workflow — dev→TestPyPI, master→PyPI

Branch model:
- feature/* → PR → dev (TestPyPI auto-publish) → PR → master (PyPI)
- master always matches latest PyPI release
- dev is the integration/staging branch

CI changes:
- ci.yml: TestPyPI publish triggers on dev push (was master)
- ci.yml, codeql.yml: CI runs on both master and dev pushes
- dependabot.yml: PRs target dev branch

Hook changes:
- release-guard.sh: updated messages to mention dev branch
- release-guard-mcp.sh: updated messages to mention dev branch
- Both hooks already allow dev pushes (only block master/main)

Documentation:
- CLAUDE.md: updated 3-phase workflow, CI table, release guard docs
- dev-workflow.md: added branch model section
- release-discipline.md: added dev branch staging notes

* ci: retrigger CI for PR #160

* feat: allow Claude Code to merge PRs targeting dev branch only

Release guard hooks now check the PR's base branch:
- dev → allowed (TestPyPI/staging)
- master/main → blocked (PyPI releases remain Nathan-only)

Both Bash hook (gh pr merge) and MCP hook (merge_pull_request)
updated with base branch checking via gh pr view.

* docs: add workflow mode indicator and modes.md to CLAUDE.md

- Reset outline state via source_has_approval tracking so future
  ExitPlanMode requests work correctly (#163)
- Sanitise text_link entities with invalid URLs (localhost, loopback,
  file paths, bare hostnames) by converting to code entities — prevents
  silent 400 errors that drop the entire final message (#157)
- Merge v0.34.5 changelog into v0.35.0 — v0.34.5 was never released
  (latest PyPI is v0.34.4), all rc1-rc7 work is v0.35.0

17 new tests (2 for #163, 15 for #157).

- _frozen_ring_count tracking and ring buffer snapshot comparison
- frozen_escalate gating (fires notification after 3+ frozen checks
  despite cpu_active=True)
- _has_running_mcp_tool() for MCP server name extraction
- _STALL_THRESHOLD_MCP_TOOL (15 min, configurable via watchdog)
- MCP-aware notification text ("MCP tool may be hung", "CPU active,
  no new events", "MCP tool running")
- 8 new tests + 2 updated existing tests
- mcp_tool_timeout watchdog setting

…ll (#183, #184, #167, #168)

* fix: prevent Codex/OpenCode headless hangs (#184, #183)

Codex (#184): always pass --ask-for-approval in headless mode.
Default to "never" (auto-approve all) so Codex never blocks on
terminal input. Safe permission mode still uses "untrusted".

OpenCode (#183): surface unsupported JSONL event types as visible
Telegram warnings instead of silently dropping them. When msgspec
DecodeError occurs, _extract_event_type() tries to parse the raw
JSON for the type field. If extractable, a warning ActionEvent is
emitted (visible in Telegram) instead of returning [].

Auto-continue (#167): detect when Claude Code exits after receiving
tool results without processing them (last_event_type=user) and
auto-resume the session. Configurable via [auto_continue] with
enabled (default true) and max_retries (default 1).

Sleeping-process stall (#168): CPU-active suppression now checks
process_state; when main process is sleeping (state=S) but children
are CPU-active (hung Bash tool), notifications fire. Stall message
shows tool name ("Bash tool may be stuck") instead of generic text.

* feat: add "Let's discuss" button to post-outline plan approval

Add a 💬 Let's discuss button to the post-outline plan approval
buttons (between Approve Plan/Deny and cancel). When clicked, it
tells Claude Code to ask the user what they'd like to discuss about
the plan before deciding to approve or deny.

Implementation:
- New `chat` action in claude_control.py with `_CHAT_DENY_MESSAGE`
- Handles both da: prefix (synthetic) and hold-open (real request_id) paths
- Clears cooldown and outline_pending state on both paths
- Early toast: "Let's discuss..."
- Post-outline keyboard now has 2 rows: [Approve Plan | Deny], [Let's discuss]

Tests: 5 new tests, 5 updated for new button layout (1773 pass, 81% coverage)
Docs: updated 9 files across how-to, tutorial, reference, and rules

…tion (#220, #221)

- Read OpenCode's ~/.config/opencode/opencode.json at runner construction
  to populate the model footer even when no untether.toml override is set.
  Previously the footer showed no model for the default config. (#221)

- Update _ENGINE_MODEL_HINTS for opencode to show "provider/model
  (e.g. openai/gpt-4o)" instead of the unhelpful "from provider config",
  guiding users to use the required provider-prefixed format. (#220)

- Gate /planmode to Claude-only; gate /usage to subscription-supported
  engines; add _resolve_engine helper for command-level engine checks.

- Deduplicate repeated StartedEvent headers in /export markdown output
  for resumed sessions.

- Fix Gemini CLI prompt injection: use --prompt=<value> instead of
  -p <value> to prevent prompts starting with - being parsed as flags.

- Ensure Codex runner always includes model in meta dict.

  plus engine gate and export dedup tests.

* fix: /new command now cancels running processes before clearing sessions (#222)

Previously /new only cleared stored resume tokens, leaving old Claude/Codex/OpenCode
processes running (~400 MB each). This leaked processes and worsened memory pressure,
contributing to earlyoom kills (rc=143).

Now /new cancels all running tasks for the chat before clearing sessions. Reply
message shows "cancelled run and cleared" when a process was killed.

- Add _cancel_chat_tasks() helper to topics.py
- Add running_tasks param to both /new handlers
- Pass running_tasks through all 3 call sites in loop.py
- Add running_tasks field to TelegramCommandContext
- 10 new tests covering cancellation behaviour
- Update 7 docs to reflect new /new behaviour

…222) (#226)

When earlyoom killed Claude sessions (rc=143/SIGTERM), auto-continue detected
last_event_type=user and immediately respawned all 4 killed sessions (~5 GB of
new processes) into the same memory pressure. This caused a death spiral where
sessions were killed and respawned repeatedly.

Fix: _should_auto_continue now checks proc_returncode — signal deaths (rc>128
or rc<0) are excluded. The upstream bug #34142/#30333 exits with rc=0, so
auto-continue still works for its intended purpose.

- Add _is_signal_death() helper to runner_bridge.py
- Add proc_returncode field to JsonlStreamState
- Store returncode on stream state after process exit
- Pass proc_returncode through to _should_auto_continue
- 12 new tests for signal death detection and auto-continue gating

* fix: improve error_during_execution hint for session archival (#228)

Update error hint text from "corrupted during a restart" to "archived or
expired" — better reflects the actual cause when Claude Code auto-archives
a session between resume runs.

* fix: prevent duplicate control response for already-handled requests (#229)

When a user clicks Approve/Deny on a control request via Telegram,
send_claude_control_response() marks it in _HANDLED_REQUESTS but can't
access state.pending_control_requests. The 5-minute expiry check then
sends a duplicate DENY for the same request_id, causing Claude Code to
receive conflicting approve+deny responses and stall.

Add reconciliation in translate() that checks _HANDLED_REQUESTS against
pending_control_requests before the expiry loop:
- Removes already-handled requests from pending (prevents spurious deny)
- Emits action_completed to clear stale inline keyboards
- Adds belt-and-suspenders guard on the expiry list comprehension

The upstream Claude Code freeze is tracked in anthropics/claude-code#39666.

`/new` was only handled in `_dispatch_builtin_command()` when
`topics.enabled=true`. With topics disabled (assistant mode), the
command fell through to prompt dispatch and triggered an engine run.

- Move `/new` out of the `topics.enabled` gate, mirroring `/ctx`
  pattern: topic → `handle_new_command`, chat session →
  `handle_chat_new_command`, stateless → cancel + reply
- Add `chat_session_store` and `chat_session_key` to
  `TelegramCommandContext` dataclass
- Remove unreachable early routing for `/new` at lines 1871-1910
  (now handled by `_dispatch_builtin_command`)

Verified: all 6 engine forum topic chats return "no stored sessions"
instead of triggering runs. Project supergroup chats unaffected.

upcoming webhook http_forward, external payload fetch, and cron
data-fetch features. Blocks private/reserved IP ranges (loopback,
RFC 1918, link-local, CGN, multicast, IPv6 equivalents, IPv4-mapped
IPv6), validates URL schemes, performs DNS resolution with IP checks
to prevent DNS rebinding attacks. Includes configurable allowlist,
timeout/size clamping, and SSRFError exception.

73 tests covering IPv4/IPv6 blocking, URL validation, DNS resolution
mocking, async validation, allowlist overrides, and edge cases.

* feat: non-agent webhook actions — file_write, http_forward, notify_only (#277)

Add `action` field to webhook config with three new action types that
skip the agent run pipeline:

- `file_write` — write POST body to a file path with template
  substitution, atomic writes, path traversal protection, deny-glob
  enforcement, on-conflict handling (overwrite/append_timestamp/error)
- `http_forward` — forward payload to another URL with SSRF protection
  (#276), header template rendering with control char validation,
  exponential backoff on 5xx (max 3 retries), configurable method
- `notify_only` — send templated Telegram message, no agent run

All actions go through existing auth, rate limiting, and event filter.
Optional `notify_on_success`/`notify_on_failure` flags for Telegram
visibility. Default action is `agent_run` (fully backward compatible).

Also adds `render_template_fields()` to templating module for non-prompt
template rendering (file paths, URLs, messages) without untrusted prefix.

atomic writes), http_forward (SSRF blocking, 4xx no-retry, header
injection, template URLs), and notify_only (template rendering, no
untrusted prefix).

Extend test_trigger_settings.py (+12 tests) with action validation:
required fields per action type, backward compat for existing configs.

Extend test_trigger_templating.py (+4 tests) for render_template_fields
(no untrusted prefix variant).

Multipart support (#278):
- Webhooks accept multipart/form-data when accept_multipart=true
- File parts saved with sanitised filenames, atomic writes, deny-glob
  and path traversal protection, configurable size limits (default 50MB)
- Form fields available as template variables alongside file metadata
- New config fields: accept_multipart, file_destination, max_file_size_bytes

Cron data-fetch (#279):
- New CronFetchConfig model with type (http_get, http_post, file_read)
- HTTP fetches use SSRF protection (#276), configurable timeout, parse_as
  (json/text/lines), on_failure (abort/run_with_error)
- File reads use path traversal protection, deny-globs, symlink rejection
- Fetched data injected into prompt via store_as template variable
- CronConfig now supports prompt_template alongside static prompt
- Fetch failures send Telegram notification when on_failure=abort
- New fetch.py module with execute_fetch() and build_fetch_prompt()

Tests: 31 new tests (test_trigger_fetch.py + settings extensions)

* chore: staging 0.35.1rc2

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: multipart body consumption and rate limiter ineffectiveness (#280, #281)

Two blocker bugs surfaced during v0.35.1rc2 integration testing:

#280: multipart webhooks returned HTTP 500 with "Could not find starting
boundary". Root cause — `_process_webhook` pre-reads the full request body
for size/auth/rate-limit checks, which exhausts the aiohttp stream before
`_parse_multipart` calls `request.multipart()`. Fix: reconstruct a
`MultipartReader` from the cached raw body via a fresh `StreamReader`.
Also added a short-circuit in `execute_file_write` so the raw MIME envelope
isn't written to `file_path` in addition to the extracted file part at
`file_destination`.

#281: rate limiter never returned 429 even under heavy bursts. Root cause —
`_process_webhook` awaited `dispatcher.dispatch_webhook` / `dispatch_action`
before returning 202, which capped HTTP handler throughput at the Telegram
outbox rate (~1/sec for private chats). The token bucket refilled faster
than it drained. Fix: dispatch via `asyncio.create_task` with exception
logging, tracked in a module-level set so the GC can't drop in-flight tasks.
With `rate_limit = 60`, an 80-request burst now yields 60 × 202 + 20 × 429.

Tests: +8 regression tests covering multipart success paths (single file,
form-field + file, size limit, unsafe filename, auth rejection), rate
limit under burst, and the fire-and-forget HTTP 202 contract. Full suite
still passes (2020 tests, +1 skipped). The old `test_internal_error_returns_500`
test was adjusted to match the new fire-and-forget semantics — dispatch
errors log rather than surface as HTTP 500.

* docs: note fire-and-forget dispatch and multipart short-circuit (#280, #281)

- Update flow diagram to show HTTP 202 returns before dispatch completes.
- Clarify rate_limit docs: bursts are limited at ingress, not downstream outbox.
- Document that multipart + action=file_write saves only to file_destination.

* fix: use tempfile.gettempdir() instead of hardcoded /tmp (bandit B108)

The multipart upload fallback path (when file_destination is not configured)
previously wrote to /tmp/untether-uploads/, which bandit flagged at Medium
severity (predictable location, CWE-377) on the #278 feature branch — the
CI check never went green for that PR because bandit was failing on this
line. Switching to Path(tempfile.gettempdir()) / "untether-uploads" is
portable and silences the warning.

When diff_preview was enabled and the user approved ExitPlanMode, every
subsequent Edit/Write/Bash tool still required manual approval — defeating
the plan mode UX of "review once, execute freely". Now tracks plan exit
approval per-session and auto-approves diff_preview tools after the plan
is approved.

Also bumps to v0.35.1rc3 for staging.

Implements hot-reload for trigger configuration (crons and webhooks) via new TriggerManager class. Editing untether.toml applies changes immediately without restarting Untether or killing active runs.

- New TriggerManager class in triggers/manager.py holds cron/webhook config
- Cron scheduler reads manager.crons each tick; last_fired preserved across swaps
- Webhook server resolves routes per-request via manager.webhook_for_path()
- Config watcher handle_reload() re-reads raw TOML [triggers] section
- 13 new tests in test_trigger_manager.py; 2038 existing tests still pass

Closes #269.

…t Tier 1 (#271, #286, #287, #288)

* fix: stop Untether being the preferred OOM victim (#275)

systemd user services inherit OOMScoreAdjust=200 + OOMPolicy=stop
defaults, which made Untether's engine subprocesses preferred
earlyoom/kernel OOM killer targets ahead of CLI claude
(oom_score_adj=0) and orphaned grandchildren actually consuming the
RAM. When lba-1 ran low on RAM, live Telegram chats died with rc=143
(SIGTERM) while the processes actually eating the RAM survived.

Updates contrib/untether.service with:

- OOMScoreAdjust=-100 — documents intent; kernel clamps to the parent
  baseline for unprivileged users (typically 100), but takes effect
  if the parent user@UID.service is ever overridden lower
- OOMPolicy=continue — a single OOM-killed child no longer tears
  down the whole unit cgroup; previously every live chat died at once

Also updates docs/reference/dev-instance.md with a new OOM section
covering the asymmetry, the clamping caveat, and the optional
sudo systemctl edit user@UID.service override for operators who
want Untether's children to live longer than CLI processes.

Existing installs need to copy the unit file and
`systemctl --user daemon-reload`; staging picks up the change on
the next `scripts/staging.sh install` cycle.

* feat: v0.35.1rc4 — /at command, hot-reload bridge config, trigger visibility, restart Tier 1 (#271, #286, #287, #288)

Bundles four rc4 features plus a CHANGELOG entry for #283 (diff_preview gate,
already on dev as 8c04904). Full details in CHANGELOG.md.

#269/#285 hot-reload triggers: merged separately as PR #285 (squash-merged to
dev); this commit extends TriggerManager with rc4 helpers (remove_cron,
crons_for_chat, webhooks_for_chat, cron_ids, webhook_ids) for Features 4b and
5 below.

#288 — /at command and run_once cron flag:
- new telegram/at_scheduler.py — module-level task-group + run_job holder;
  schedule_delayed_run(), cancel_pending_for_chat(), active_count();
  per-chat cap of 20 pending delays
- new telegram/commands/at.py — AtCommand backend, /at <duration> <prompt>
  with Ns/Nm/Nh suffixes, 60s-24h range
- /cancel integration via cancel_pending_for_chat()
- drain integration via active_count() in _drain_and_exit
- entry-point at = untether.telegram.commands.at:BACKEND
- CronConfig.run_once: bool = False; scheduler removes cron after fire
  if run_once=True; re-enters on reload/restart

#286 — unfreeze TelegramBridgeConfig:
- drop frozen=True (slots preserved); add update_from(settings) method
- route_update() reads cfg.allowed_user_ids live; handle_reload() calls
  update_from() and refreshes state.forward_coalesce_s / media_group_debounce_s
- restart-only keys still warn (bot_token, chat_id, session_mode, topics,
  message_overflow); others hot-reload

#271 — trigger visibility Tier 1:
- new triggers/describe.py — describe_cron(schedule, timezone) utility
- /ping shows per-chat trigger indicator when triggers target the chat
- RunContext.trigger_source field; dispatcher sets it to cron:<id>/webhook:<id>;
  runner_bridge seeds progress_tracker.meta['trigger'] with icon + source;
  ProgressTracker.note_event merges engine meta over dispatcher meta
- format_meta_line() appends 'trigger' to footer parts
- CommandContext gains trigger_manager, default_chat_id fields (default None);
  populated by telegram/commands/dispatch.py from cfg

#287 — graceful restart Tier 1:
- new sdnotify.py — stdlib sd_notify client (READY=1 / STOPPING=1);
  poll_updates sends READY=1 after _send_startup succeeds;
  _drain_and_exit sends STOPPING=1 at drain start
- new telegram/offset_persistence.py — DebouncedOffsetWriter; loads saved
  update_id on startup, persists via on_offset_advanced callback in
  poll_incoming; flushes in poll_updates finally block
- contrib/untether.service: Type=notify, NotifyAccess=main, RestartSec=2

Tests: +224 tests added across 6 new test files and 6 extended files;
2164 total tests pass with 81.55% coverage.

Context files (CLAUDE.md, .claude/rules/*) and human docs (README, triggers
reference, dev-instance, integration-testing, webhooks-and-cron how-to,
commands-and-directives) updated. rc4 integration test scenarios R1-R10
added to integration-testing.md.

* fix: prevent /at timers from firing after /cancel (CancelScope race)

anyio.CancelScope.__exit__ swallows the Cancelled exception when the
scope itself caused the cancellation. The fire/dispatch code outside
the scope continued regardless. Added cancelled_caught check after
the scope exits to prevent stale timers from dispatching.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: add v0.35.1rc4 integration test plan

52-test plan covering all rc4 features: /at command, run_once,
hot-reload (triggers + bridge config), trigger visibility,
graceful restart Tier 1, plus standard Tier 1/6/7 regression.

Includes correct dev bot chat IDs (Bot API + Telethon MCP mapping),
pre-test trigger config, results template, and known caveats.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: update integration test chat IDs to current dev bot

The old ut-dev-hf: chat IDs (5171122044 etc.) belong to a different
bot (ID 8485467124). Updated both docs to the current @untether_dev_bot
chats with both Telethon and Bot API ID forms. Added note about
Telegram MCP PeerUser fallback for channel/supergroup IDs.

* docs: comprehensive v0.35.1 documentation updates

HIGH priority:
- config.md: add run_once to cron table, fix watch_config description
  to list hot-reloadable vs restart-only settings
- operations.md: fix hot-reload section (transport settings ARE now
  partially hot-reloadable), add /ping trigger format, update_id
  persistence, systemd section with Type=notify/OOM notes
- schedule-tasks.md: add /at command section with examples, run_once
  mention

MEDIUM priority:
- triggers.md: remove duplicate hot-reload section, keep authoritative
  version with watch_config requirement and last_fired note
- CLAUDE.md: add diff_preview plan bypass (#283) to features list
- troubleshooting.md: add entries for config hot-reload issues and
  /at delay not firing

LOW priority:
- security.md: document untrusted-payload prefix for webhooks/cron
- voice-notes.md: note that voice settings hot-reload
- specification.md: bump version to v0.35.1
- tutorials: update version numbers from 0.35.0 to 0.35.1

* fix: add 38 missing structlog calls across 13 files (logging audit)

Comprehensive logging audit found gaps in security-critical paths
(auth, rate limiting, SSRF), runner lifecycle (codex peer parity),
state mutations (topic_state), and CLI error paths. Adds structured
log statements at appropriate levels without over-logging.

* docs: comprehensive v0.35.1 documentation updates

- Expand docs/reference/changelog.md with full v0.35.1 entry (security,
  fixes, changes) instead of a stub pointing to GitHub
- Add #190 (token redaction) and #191 (line buffer cap) to CHANGELOG.md
- Add logging audit (#299) to CHANGELOG.md and docs changelog
- Update CLAUDE.md test count from 2038 to 2165

Two bugs in scripts/healthcheck.sh made post-deploy health checks unusable:

1. pass()/fail() used `((var++))` which returns the pre-increment value.
   On first call (var=0) that trips `set -e`, so only the first check ever
   ran and the script always exited 1. Switched to explicit assignment.

2. The error-log count piped journalctl through `grep -c .`, which counts
   journalctl's `-- No entries --` meta line as a match, producing a
   false-positive "1 ERROR-level log entries in last 60s" on clean
   systems. Now filters meta lines with `grep -vc '^-- '`.

Verified with `scripts/healthcheck.sh --version 0.35.1rc5` on staging:
all 5 checks run, exit 0.

Closes #302
