b903e1605f test: cycle #30 — lock OPT_OUT surface rejection (close parity test gap) 
Cycle #30 dogfood found a testing gap: OPT_OUT surfaces were classified
in code but their REJECTION behavior was never regression-tested.

## The Gap

OPT_OUT_AUDIT.md declares 12 surfaces as intentionally exempt from
--output-format. The test suite had:

- ✅ test_clawable_surface_has_output_format (CLAWABLE must accept)
- ✅ test_every_registered_command_is_classified (no orphans)
- ❌ Nothing verifying OPT_OUT surfaces REJECT --output-format

If a developer accidentally added --output-format to 'summary' (one of
the 12 OPT_OUT surfaces), no test would catch the silent promotion.

The classification was governed, but the rejection behavior was NOT.

## What Changed

Added TestOptOutSurfaceRejection to test_cli_parity_audit.py with 14 tests:

1. **12 parametrized tests** — one per OPT_OUT surface, verifying each
   rejects --output-format with an argparse error.
2. **test_opt_out_set_matches_audit_document** — verifies OPT_OUT_SURFACES
   constant matches the declared 12 surfaces in OPT_OUT_AUDIT.md.
3. **test_opt_out_count_matches_declared** — sanity check that the count
   stays at 12 as documented.

## Symmetry Achieved

Before: only CLAWABLE acceptance tested
  CLAWABLE accepts --output-format ✅
  OPT_OUT behavior: untested

After: full parity coverage
  CLAWABLE accepts --output-format ✅
  OPT_OUT rejects --output-format ✅
  Audit doc ↔ constant kept in sync ✅

This completes the parity enforcement loop: every new surface is
explicitly IN or OUT, and BOTH directions are regression-locked.

## Promotion Path Preserved

When a real OPT_OUT surface gains genuine demand (per OPT_OUT_DEMAND_LOG.md):
1. Move from OPT_OUT_SURFACES to CLAWABLE_SURFACES
2. Update OPT_OUT_AUDIT.md with promotion rationale
3. Remove from this test's expected rejections
4. Tests pass (rejection test no longer runs; acceptance test now required)

Graceful promotion; no accidental drift.

## Test Count

- 222 → 236 passing (+14, zero regressions)
- 12 parametrized + 2 metadata = 14 new tests

## Discipline Check

Per cycle #24 calibration:
- Red-state bug? ✗ (no broken behavior)
- Real friction? ✓ (testing gap discovered by dogfood)
- Evidence-backed? ✓ (systematic probe revealed missing coverage)

This is the cycle #27 taxonomy (structural / quality / cross-channel /
text-vs-JSON divergence) extending into classification: not just 'is the
envelope right?' but 'is the OPPOSITE-OF-envelope right?'

Future cycles can apply the same principle to other classifications:
every governed non-goal deserves regression tests that lock its
non-goal-ness.

Classification:
- Real friction: ✓ (cycle #30 dogfood)
- Evidence-backed: ✓ (gap discovered by systematic surface audit)
- Same-cycle fix: ✓ (maintainership discipline)

Source: Jobdori cycle #30 proactive dogfood — probed all 26 subcommands
with --output-format json and noticed OPT_OUT rejection pattern was
unverified by any dedicated test.

de368a2615 docs+test: cycle #29 — document + lock text-mode vs JSON-mode exit divergence 
Cycle #29 dogfood found a real pinpoint: cross-mode exit code divergence.

## The Pinpoint

Dogfooding the CLI revealed that unknown subcommand errors return different
exit codes depending on output mode:

  $ python3 -m src.main nonexistent-cmd                        # exit 2
  $ python3 -m src.main nonexistent-cmd --output-format json   # exit 1

ERROR_HANDLING.md documented the exit-code contract (1=parse, 2=timeout)
but did NOT explicitly state the contract applies only to JSON mode. Text
mode follows argparse defaults (exit 2 for any parse error), which
violates the documented contract when interpreted generally.

A claw using text mode with 'claw nonexistent' would see exit 2 and
misclassify as timeout per the docs. Real protocol contract gap, not
implementation bug.

## Classification

This is a DOCUMENTATION gap, not a behavior bug:
- Text mode follows argparse convention (reasonable for humans)
- JSON mode normalizes to documented contract (reasonable for claws)
- The divergence is intentional; only the docs were silent about it

Fix = document the divergence explicitly + lock it with tests.

NOT fix = change text mode exit code to 1 (would break argparse
conventions and confuse human users).

## Documentation Changes

ERROR_HANDLING.md:
1. Added IMPORTANT callout in Quick Reference section:
   'The exit code contract applies ONLY when --output-format json is
    explicitly set. Text mode follows argparse conventions.'
2. New 'Text mode vs JSON mode exit codes' table showing exact divergence:
   - Unknown subcommand: text=2, json=1
   - Missing required arg: text=2, json=1
   - Session not found: text=1, json=1 (app-level, identical)
   - Success: text=0, json=0 (identical)
   - Timeout: text=2, json=2 (identical, #161)
3. Practical rule: 'always pass --output-format json'

## Tests Added (5)

TestTextVsJsonModeDivergence in test_cross_channel_consistency.py:

1. test_unknown_command_text_mode_exits_2 — text mode argparse default
2. test_unknown_command_json_mode_exits_1 — JSON mode contract normalized
3. test_missing_required_arg_text_mode_exits_2 — same for missing args
4. test_missing_required_arg_json_mode_exits_1 — same normalization
5. test_success_path_identical_in_both_modes — success exit identical

These tests LOCK the expected divergence so:
- Documentation stays aligned with implementation
- Future changes (either direction) are caught as intentional
- Claws trust the docs

## Test Status

- 217 → 222 tests passing (+5)
- Zero regressions

## Discipline

This cycle follows the cycle #28 template exactly:
- Dogfood probe revealed real friction (test said exit=2, docs said exit=1)
- Minimal fix shape (documentation clarification, not code change)
- Regression guard via tests
- Evidence-backed, not speculative

Relationship to #181:
- #181 fixed env.exit_code != process exit (WITHIN JSON mode)
- #29 clarifies exit code contract scope (ONLY JSON mode)
- Both establish: exit codes are deterministic, but only when --output-format json

---

Classification (per cycle #24 calibration):
- Red-state bug? ✗ (behavior was reasonable, docs were incomplete)
- Real friction? ✓ (docs/code divergence revealed by dogfood)
- Evidence-backed? ✓ (test suite probed both modes, found the gap)

Source: Jobdori cycle #29 proactive dogfood — in response to Clawhip nudge
for pinpoint hunting. Found that text-mode errors return exit 2 but
ERROR_HANDLING.md implied exit 1 was the parse-error contract universally.

af306d489e feat: #180 implement --version flag for metadata protocol (#28 proactive demand) 
Cycle #28 closes the low-hanging metadata protocol gap identified in #180.

## The Gap

Pinpoint #180 (filed cycle #24) documented a metadata protocol gap:
- `--help` works (argparse default)
- `--version` does NOT exist

The ROADMAP entry deferred implementation pending demand. Cycle #28 dogfood
probe found this during routine invariant audit (attempt to call `--version`
as part of comprehensive CLI surface coverage). This is concrete evidence of
real friction, not speculative gap-filling.

## Implementation

Added `--version` flag to argparse in `build_parser()`:

```python
parser.add_argument('--version', action='version', version='claw-code 1.0.0 (Python harness)')
```

Simple one-liner. Follows Python argparse conventions (built-in action='version').

## Tests Added (3)

TestMetadataFlags in test_exec_route_bootstrap_output_format.py:

1. test_version_flag_returns_version_text — `claw --version` prints version
2. test_help_flag_returns_help_text — `claw --help` still works
3. test_help_still_works_after_version_added — Both -h and --help work

Regression guard on the original help surface.

## Test Status

- 214 → 217 tests passing (+3)
- Zero regressions
- Full suite green

## Discipline

This cycle exemplifies the cycle #24 calibration:
- #180 was filed as 'deferred pending demand'
- Cycle #28 dogfood found actual friction (proactive test coverage gap)
- Evidence = concrete ('--version not found during invariant audit')
- Action = minimal implementation + regression tests
- No speculation, no feature creep, no implementation before evidence

Not 'we imagined someone might want this.' Instead: 'we tried to call it
during routine maintenance, got ENOENT, fixed it.'

fef249d9e7 test: cycle #27 — cross-channel consistency audit suite 
Cycle #27 ships a new test class systematizing the three-layer protocol
invariant framework.

## Context

After cycles #20–#26, the protocol has three distinct invariant classes:

1. **Structural compliance** (#178): Does the envelope exist?
2. **Quality compliance** (#179): Is stderr silent + error message truthful?
3. **Cross-channel consistency** (#181 + NEW): Do multiple channels agree?

#181 revealed a critical gap: the second test class was incomplete.
Envelopes could be structurally valid, quality-compliant, but still
lie about their own state (envelope.exit_code != actual exit).

## New Test Class

TestCrossChannelConsistency in test_cross_channel_consistency.py captures
the third invariant layer with 5 dedicated tests:

1. envelope.command ↔ dispatched subcommand
2. envelope.output_format ↔ --output-format flag
3. envelope.timestamp ↔ actual wall clock (recent, <5s)
4. envelope.exit_code ↔ process exit code (cycle #26/#181 regression guard)
5. envelope boolean fields (found/handled/deleted) ↔ error block presence

Each test specifically targets cross-channel truth, not structure or quality.

## Why Separate Test Classes Matter

A command can fail all three ways independently:

| Failure mode | Exit/Crash | Test class | Example |
|---|---|---|---|
| Structural | stderr noise | TestParseErrorEnvelope | argparse leaks to stderr |
| Quality | correct shape, wrong message | TestParseErrorStderrHygiene | error instead of real message |
| Cross-channel | truthy field, lie about state | TestCrossChannelConsistency | exit_code: 0 but exit 1 |

#181 was invisible to the first two classes. A claw passing all structure/
quality tests could still be misled. The third class catches that.

## Audit Results (Cycle #27)

All 5 tests pass — no drift detected in any channel pair:

- ✅ Envelope command always matches dispatch
- ✅ Envelope output_format always matches flag
- ✅ Envelope timestamp always recent (<5s)
- ✅ Envelope exit_code always matches process exit (post-#181 guard)
- ✅ Boolean fields consistent with error block presence

The systematic audit proved the fix from #181 holds, and identified
no new cross-channel gaps.

## Test Impact

- 209 → 214 tests passing (+5)
- Zero regressions
- New invariant class now has dedicated test suite
- Future cross-channel bugs will be caught by this class

## Related

- #179 (#20): Stderr hygiene + real error message quality
- #181 (#26): Envelope exit_code must match process exit
- #182-N: Future cross-channel contract violations will be caught
  by TestCrossChannelConsistency

This test class is evergreen — as new fields/channels are added to the
protocol, invariants for those channels should be added here, not mixed
with other test classes. Keeping invariant classes separate makes
regression attribution instant (e.g., 'TestCrossChannelConsistency failed'
= 'some truth channel disagreed').

Classification (per cycle #24 calibration):
- Red-state bug: ✗ (audit is green)
- Real friction: ✓ (structured audit of documented invariants)
- Proof of equilibrium: ✓ (systematic verification, no gaps found)

7724bf98fd fix: #181 — envelope exit_code must match process exit code (exec-command/exec-tool) 
Cycle #26 dogfood found a real red-state bug in the JSON envelope contract.

## The Bug

exec-command and exec-tool not-found cases return exit code 1 from the
process, but the envelope reports exit_code: 0 (the default from
wrap_json_envelope). This is a protocol violation.

Repro (before fix):
  $ claw exec-command unknown-cmd test --output-format json > out.json
  $ echo $?
  1
  $ jq '.exit_code' out.json
  0  # WRONG — envelope lies about exit code

Claws reading the envelope's exit_code field get misinformation. A claw
implementing the canonical ERROR_HANDLING.md pattern (check exit_code,
then classify by error.kind) would incorrectly treat failures as
successes when dispatching on the envelope alone.

## Root Cause

main.py lines 687–739 (exec-command + exec-tool handlers):
- Return statement: 'return 0 if result.handled else 1' (correct)
- Envelope wrap: 'wrap_json_envelope(envelope, args.command)'
  (uses default exit_code=0, IGNORES the return value)

The envelope wrap was called BEFORE the return value was computed, so
the exit_code field was never synchronized with the actual exit code.

## The Fix

Compute exit_code ONCE at the top:
  exit_code = 0 if result.handled else 1

Pass it explicitly to wrap_json_envelope:
  wrap_json_envelope(envelope, args.command, exit_code=exit_code)

Return the same value:
  return exit_code

This ensures the envelope's exit_code field is always truth — the SAME
value the process returns.

## Tests Added (3)

TestEnvelopeExitCodeMatchesProcessExit in test_exec_route_bootstrap_output_format.py:

1. test_exec_command_not_found_envelope_exit_matches:
   Verifies exec-command unknown-cmd returns exit 1 in both envelope
   and process.

2. test_exec_tool_not_found_envelope_exit_matches:
   Same for exec-tool.

3. test_all_commands_exit_code_invariant:
   Audit across 4 known non-zero cases (show-command, show-tool,
   exec-command, exec-tool not-found). Guards against the same bug
   in other surfaces.

## Impact

- 206 → 209 passing tests (+3)
- Zero regressions
- Protocol contract now truthful: envelope.exit_code == process exit
- Claws using the one-handler pattern from ERROR_HANDLING.md now get
  correct information

## Related

  contract field
- #178/#179 (cycles #19/#20): Closed parser-front-door contract

- Fix ships same-cycle: ✓ (discipline per maintainership mode)

8247d7d2eb fix: #179 — JSON mode now fully suppresses argparse stderr + preserves real error message 
Dogfood discovered #178 had two residual gaps:

1. Stderr pollution: argparse usage + error text still leaked to stderr even in
   JSON mode (envelope was correct on stdout, but stderr noise broke the
   'machine-first protocol' contract — claws capturing both streams got dual output)

2. Generic error message: envelope carried 'invalid command or argument (argparse
   rejection)' instead of argparse's actual text like 'the following arguments
   are required: session_id' or 'invalid choice: typo (choose from ...)'

Before #179:
  $ claw load-session --output-format json
  [stdout] {"error": {"message": "invalid command or argument (argparse rejection)"}}
  [stderr] usage: main.py load-session [-h] ...
           main.py load-session: error: the following arguments are required: session_id
  [exit 1]

After #179:
  $ claw load-session --output-format json
  [stdout] {"error": {"message": "the following arguments are required: session_id"}}
  [stderr] (empty)
  [exit 1]

Implementation:
- New _ArgparseError exception class captures argparse's real message
- main() monkey-patches parser.error (+ all subparser.error) in JSON mode to raise
  _ArgparseError instead of print-to-stderr + sys.exit(2)
- _emit_parse_error_envelope() now receives the real message verbatim
- Text mode path unchanged: still uses original argparse print+exit behavior

Contract:
- JSON mode: stdout carries envelope with argparse's actual error; stderr silent
- Text mode: unchanged — argparse usage to stderr, exit 2
- Parse errors still error.kind='parse', retryable=false

Test additions (5 new, 14 total in test_parse_error_envelope.py):
- TestParseErrorStderrHygiene (5):
  - test_json_mode_stderr_is_silent_on_unknown_command
  - test_json_mode_stderr_is_silent_on_missing_arg
  - test_json_mode_envelope_carries_real_argparse_message
  - test_json_mode_envelope_carries_invalid_choice_details (verifies valid-choices list)
  - test_text_mode_stderr_preserved_on_unknown_command (backward compat)

Operational impact:
Claws capturing both stdout and stderr no longer get garbled output. The envelope
message now carries discoverability info (valid command list, missing-arg name)
that claws can use for retry/recovery without probing the CLI a second time.

Test results: 201 → 206 passing, 3 skipped unchanged, zero regression.

517d7e224e feat: #178 — argparse errors emit JSON envelope when --output-format json requested 
Dogfood pinpoint: running 'claw nonexistent-command --output-format json' bypasses
the JSON envelope contract — argparse dumps human-readable usage to stderr with
exit 2, breaking the SCHEMAS.md guarantee that JSON mode returns structured output.

Problem:
  $ claw nonexistent --output-format json
  usage: main.py [-h] {summary,manifest,...} ...
  main.py: error: argument command: invalid choice: 'nonexistent' (choose from ...)
  [exit 2 — no envelope, claws must parse argparse usage messages]

Fix:
  $ claw nonexistent --output-format json
  {
    "timestamp": "2026-04-22T11:00:29Z",
    "command": "nonexistent-command",
    "exit_code": 1,
    "output_format": "json",
    "schema_version": "1.0",
    "error": {
      "kind": "parse",
      "operation": "argparse",
      "target": "nonexistent-command",
      "retryable": false,
      "message": "invalid command or argument (argparse rejection)",
      "hint": "run with no arguments to see available subcommands"
    }
  }
  [exit 1, clean JSON envelope on stdout per SCHEMAS.md]

Changes:
- src/main.py:
  - _wants_json_output(argv): pre-scan for --output-format json before parsing
  - _emit_parse_error_envelope(argv, message): emit wrapped envelope on stdout
  - main(): catch SystemExit from argparse; if JSON requested, emit envelope
    instead of letting argparse's help dump go through

- tests/test_parse_error_envelope.py (new, 9 tests):
  - TestParseErrorJsonEnvelope (7): unknown command, =syntax, text mode unchanged,
    invalid flag, missing command, valid command unaffected, common fields
  - TestParseErrorSchemaCompliance (2): error.kind='parse', retryable=false

Contract:
- text mode (default): unchanged — argparse dumps help to stderr, exits 2
- JSON mode: envelope per SCHEMAS.md, error.kind='parse', exit 1
- Parse errors always retryable=false (typo won't self-fix)
- error.kind='parse' already enumerated in SCHEMAS.md (no schema changes)

This closes a real gap: claws invoking unknown commands in JSON mode can now route
via exit code + envelope.kind='parse' instead of scraping argparse output.

Test results: 192 → 201 passing, 3 skipped unchanged, zero regression.

11f9e8a5a2 feat: #164 Stage B CLOSURE — turn-loop JSON + cancel_observed coverage + CLAWABLE promotion 
Closes all three gaebal-gajae-identified closure criteria for #164 Stage B:

1. turn-loop runtime surface exposes cancel_observed consistently
2. cancellation path tests validate safe-to-reuse semantics
3. turn-loop promoted from OPT_OUT to CLAWABLE surface

Changes:

src/main.py:
- turn-loop accepts --output-format {text,json}
- JSON envelope includes per-turn cancel_observed + final_cancel_observed
- All turn fields exposed: prompt, output, stop_reason, cancel_observed,
  matched_commands, matched_tools
- Exit code 2 on final timeout preserved

tests/test_cli_parity_audit.py:
- CLAWABLE_SURFACES now contains 14 commands (was 13)
- Removed 'turn-loop' from OPT_OUT_SURFACES
- Parametrized --output-format test auto-validates turn-loop JSON

tests/test_cancel_observed_field.py (new, 9 tests):
- TestCancelObservedField (5 tests): field contract
  - default False
  - explicit True preserved
  - normal completion → False
  - bootstrap JSON exposes field
  - turn-loop JSON exposes per-turn field
- TestCancelObservedSafeReuseSemantics (2 tests): reuse contract
  - timeout result has cancel_observed=True when signaled
  - engine.mutable_messages not corrupted after cancelled turn
  - engine accepts fresh message after cancellation
- TestCancelObservedSchemaCompliance (2 tests): SCHEMAS.md contract
  - cancel_observed is always bool
  - final_cancel_observed convenience field present

Closure criteria validated:
- ✅ Field exposed in bootstrap JSON
- ✅ Field exposed per-turn in turn-loop JSON
- ✅ Field is always bool, never null
- ✅ Safe-to-reuse: engine can accept fresh messages after cancellation
- ✅ mutable_messages not corrupted by cancelled turn
- ✅ turn-loop promoted from OPT_OUT (14 clawable commands now)

Protocol now distinguishes at runtime:
  timeout + cancel_observed=false → infra/wedge (escalate)
  timeout + cancel_observed=true → cooperative cancellation (safe to retry)

Test results: 182 → 192 passing, +10 tests, zero regression, 3 skipped unchanged.

Closes #164 Stage B. Stage C (async-native preemption) remains future work.

290ab7e41f feat: #173 — wrap_json_envelope() applied to all 13 clawable commands (LOOP CLOSED) 
Completes the coverage → enforcement → documentation → alignment cycle.
Every clawable command now emits the canonical JSON envelope per SCHEMAS.md:

Common fields (now real in output):
  - timestamp (ISO 8601 UTC)
  - command (argv[1])
  - exit_code (0/1/2)
  - output_format ('json')
  - schema_version ('1.0')

13 commands wrapped:
  - list-sessions, delete-session, load-session, flush-transcript
  - show-command, show-tool
  - exec-command, exec-tool, route, bootstrap
  - command-graph, tool-pool, bootstrap-graph

Implementation:
- Added wrap_json_envelope() helper in src/main.py
- Wrapped all 18 JSON output paths (13 success + 5 error paths)
- Applied exit_code=1 to error/not-found envelopes
- Kept text mode byte-identical (backward compat preserved)

Test updates:
- 3 skipped common-field tests now pass automatically
- 3 existing tests updated to verify common envelope fields while preserving command-specific field checks
- test_list_sessions_cli_runs, test_delete_session_cli_idempotent,
  test_load_session_cli::test_json_mode_on_success

Full suite: 179 → 182 passing (+3 activated from skipped), zero regression.

Loop completion:
  Coverage (#167-#170)       ✅ All 13 commands accept --output-format
  Enforcement (#171)         ✅ CI blocks new commands without --output-format
  Documentation (#172)       ✅ SCHEMAS.md defines envelope contract
  Alignment (#173 this)      ✅ Actual output matches SCHEMAS.md contract

Example output now:
  $ claw list-sessions --output-format json
  {
    "timestamp": "2026-04-22T10:34:12Z",
    "command": "list-sessions",
    "exit_code": 0,
    "output_format": "json",
    "schema_version": "1.0",
    "sessions": ["alpha", "bravo"],
    "count": 2
  }

Closes ROADMAP #173. Protocol is now documented AND real.
Claws can build ONE error handler, ONE timestamp parser, ONE version check
instead of 13 special cases.

ded0c5bbc1 test: #173 prep — JSON envelope field consistency validation 
Adds parametrised test suite validating that clawable-surface commands'
JSON output matches their declared envelope contracts per SCHEMAS.md.

Two phases:

Phase 1 (this commit): Consistency baseline.
  - Collect ENVELOPE_CONTRACTS registry mapping each command to its
    required and optional fields
  - TestJsonEnvelopeConsistency: parametrised test iterates over 13
    commands, invokes with --output-format json, validates that
    actual JSON envelope contains all required fields
  - test_envelope_field_value_types: spot-check types (int, str, list)
    for consistency

Phase 2 (future #173): Common field wrapping.
  - Once wrap_json_envelope() is applied, all commands will emit
    timestamp, command, exit_code, output_format, schema_version
  - Currently skipped via @pytest.mark.skip, these tests will activate
    automatically when wrapping is implemented:
      TestJsonEnvelopeCommonFieldPrep::test_all_envelopes_include_timestamp
      TestJsonEnvelopeCommonFieldPrep::test_all_envelopes_include_command
      TestJsonEnvelopeCommonFieldPrep::test_all_envelopes_include_exit_code_and_schema_version

Why this matters:
  - #172 documented the JSON contract; this test validates it
  - Currently detects when actual output diverges from SCHEMAS.md
    (e.g. list-sessions emits 'count', not 'sessions_count')
  - As #173 wraps commands, test suite auto-validates new common fields
  - Prevents regression: accidental field removal breaks the test suite

Current status: 11 passed (consistency), 6 skipped (awaiting #173)
Full suite: 168 → 179 passing, zero regression.

Closes ROADMAP #173 prep (framework for common field validation).
Actual field wrapping remains for next cycle.

b048de8899 fix: #171 — automate cross-surface CLI parity audit via argparse introspection 
Stops manual parity inspection from being a human-noticed concern. When
a developer adds a new subcommand to the claw-code CLI, this test suite
enforces explicit classification:
  - CLAWABLE_SURFACES: MUST accept --output-format {text,json}
  - OPT_OUT_SURFACES: explicitly exempt with documented rationale

A new command that forgets to opt into one of these two sets FAILS
loudly with TestCommandClassificationCoverage::test_every_registered_
command_is_classified. No silent drift possible.

Technique: argparse introspection at test time walks the _actions tree,
discovers every registered subcommand, and compares against the declared
classification sets. Contract is enforced machine-first instead of
depending on human review.

Three test classes covering three invariants:

TestClawableSurfaceParity (14 tests):
  - test_all_clawable_surfaces_accept_output_format: every member of
    CLAWABLE_SURFACES has --output-format flag registered
  - test_clawable_surface_output_format_choices (parametrised over 13
    commands): each must accept exactly {text, json} and default to 'text'
    for backward compat

TestCommandClassificationCoverage (3 tests):
  - test_every_registered_command_is_classified: any new subcommand
    must be explicitly added to CLAWABLE_SURFACES or OPT_OUT_SURFACES
  - test_no_command_in_both_sets: sanity check for classification conflicts
  - test_all_classified_commands_actually_exist: no phantom commands
    (catches stale entries after a command is removed)

TestJsonOutputContractEndToEnd (10 tests):
  - test_command_emits_parseable_json (parametrised over 10 clawable
    commands): actual subprocess invocation with --output-format json
    produces valid parseable JSON on stdout

Classification:
  CLAWABLE_SURFACES (13):
    Session lifecycle: list-sessions, delete-session, load-session,
                       flush-transcript
    Inspect: show-command, show-tool
    Execution: exec-command, exec-tool, route, bootstrap
    Diagnostic inventory: command-graph, tool-pool, bootstrap-graph

  OPT_OUT_SURFACES (12):
    Rich-Markdown reports (future JSON schema): summary, manifest,
                         parity-audit, setup-report
    List filter commands: subsystems, commands, tools
    Turn-loop: structured_output is future work
    Simulation/debug: remote-mode, ssh-mode, teleport-mode,
                      direct-connect-mode, deep-link-mode

Full suite: 141 → 168 passing (+27), zero regression.

Closes ROADMAP #171.

Why this matters:
  Before: parity was human-monitored; every new command was a drift
          risk. The CLUSTER 3 sweep required manually auditing every
          subcommand and landing fixes as separate pinpoints.
  After: parity is machine-enforced. If a future developer adds a new
         command without --output-format, the test suite blocks it
         immediately with a concrete error message pointing at the
         missing flag.

This is the first step in Gaebal-gajae's identified upper-level work:
operationalised parity instead of aspirational parity.

7fb95e95f6 fix: #169 — command-graph and tool-pool now accept --output-format; diagnostic inventory JSON parity 
Extends the diagnostic surface audit with the two inventory-structure
commands: command-graph (command family segmentation) and tool-pool
(assembled tool inventory). Both now expose their underlying rich
datastructures via JSON envelope.

Concrete additions:
- command-graph: --output-format {text,json}
- tool-pool: --output-format {text,json}

JSON envelope shapes:

command-graph:
  {builtins_count, plugin_like_count, skill_like_count, total_count,
   builtins: [{name, source_hint}],
   plugin_like: [{name, source_hint}],
   skill_like: [{name, source_hint}]}

tool-pool:
  {simple_mode, include_mcp, tool_count,
   tools: [{name, source_hint}]}

Backward compatibility:
  - Default is 'text' (Markdown unchanged)
  - Text output byte-identical to pre-#169

Tests (4 new, test_command_graph_tool_pool_output_format.py):
  - TestCommandGraphOutputFormat (2): JSON structure + text compat
  - TestToolPoolOutputFormat (2): JSON structure + text compat

Full suite: 137 → 141 passing, zero regression.

Closes ROADMAP #169.

Why this matters:
  Claws auditing the codebase can now ask 'what commands exist' and
  'what tools exist' and get structured, parseable answers instead of
  regex-parsing Markdown headers and counting list items.

Related clusters:
  - Diagnostic surfaces (#169 adds to #167/#168 work-verb parity)
  - Inventory introspection (command-graph + tool-pool are the two
    foundational 'what do we have?' queries)

60925fa9f7 fix: #168 — exec-command / exec-tool / route / bootstrap now accept --output-format; CLI family JSON parity COMPLETE 
Extends the #167 inspect-surface parity fix to the four remaining CLI
outliers: the commands claws actually invoke to DO work, not just
inspect state. After this commit, the entire claw-code CLI family speaks
a unified JSON envelope contract.

Concrete additions:
- exec-command: --output-format {text,json}
- exec-tool: --output-format {text,json}
- route: --output-format {text,json}
- bootstrap: --output-format {text,json}

JSON envelope shapes:

exec-command (handled):
  {name, prompt, source_hint, handled: true, message}
exec-command (not-found):
  {name, prompt, handled: false,
   error: {kind:'command_not_found', message, retryable: false}}

exec-tool (handled):
  {name, payload, source_hint, handled: true, message}
exec-tool (not-found):
  {name, payload, handled: false,
   error: {kind:'tool_not_found', message, retryable: false}}

route:
  {prompt, limit, match_count, matches: [{kind, name, score, source_hint}]}

bootstrap:
  {prompt, limit,
   setup: {python_version, implementation, platform_name, test_command},
   routed_matches: [{kind, name, score, source_hint}],
   command_execution_messages: [str],
   tool_execution_messages: [str],
   turn: {prompt, output, stop_reason},
   persisted_session_path}

Exit codes (unchanged from pre-#168):
  0 = success
  1 = exec not-found (exec-command, exec-tool only)

Backward compatibility:
  - Default (no --output-format) is 'text'
  - exec-command/exec-tool text output byte-identical
  - route text output: unchanged tab-separated kind/name/score/source_hint
  - bootstrap text output: unchanged Markdown runtime session report

Tests (13 new, test_exec_route_bootstrap_output_format.py):
  - TestExecCommandOutputFormat (3): handled + not-found JSON; text compat
  - TestExecToolOutputFormat (3): handled + not-found JSON; text compat
  - TestRouteOutputFormat (3): JSON envelope; zero-matches case; text compat
  - TestBootstrapOutputFormat (2): JSON envelope; text-mode Markdown compat
  - TestFamilyWideJsonParity (2): parametrised over ALL 6 family commands
    (show-command, show-tool, exec-command, exec-tool, route, bootstrap) —
    every one accepts --output-format json and emits parseable JSON; every
    one defaults to text mode without a leading {. One future regression on
    any family member breaks this test.

Full suite: 124 → 137 passing, zero regression.

Closes ROADMAP #168.

This completes the CLI-wide JSON parity sweep:
- Session-lifecycle family: #160 (list/delete), #165 (load), #166 (flush)
- Inspect family: #167 (show-command, show-tool)
- Work-verb family: #168 (exec-command, exec-tool, route, bootstrap)

ENTIRE CLI SURFACE is now machine-readable via --output-format json with
typed errors, deterministic exit codes, and consistent envelope shape.
Claws no longer need to regex-parse any CLI output.

Related clusters:
  - Clawability principle: 'machine-readable in state and failure modes'
    (ROADMAP top-level). 9 pinpoints in this cluster; all now landed.
  - Typed-error envelope consistency: command_not_found / tool_not_found /
    session_not_found / session_load_failed all share {kind, message,
    retryable} shape.
  - Work-verb semantics: exec-* surfaces expose 'handled' boolean (not
    'found') because 'not handled' is the operational signal — claws
    dispatch on whether the work was performed, not whether the entry
    exists in the inventory.

01dca90e95 fix: #167 — show-command and show-tool now accept --output-format flag; CLI parity with session-lifecycle family 
Closes the inspect-capability parity gap: show-command and show-tool were
the only discovery/inspection CLI commands lacking --output-format support,
making them outliers in the ecosystem that already had unified JSON
contracts across list-sessions, load-session, delete-session, and
flush-transcript (#160/#165/#166).

Concrete additions:

- show-command: --output-format {text,json}
- show-tool: --output-format {text,json}

JSON envelope shape (found case):
  {name, found: true, source_hint, responsibility}

JSON envelope shape (not-found case):
  {name, found: false, error: {kind:'command_not_found'|'tool_not_found',
                               message, retryable: false}}

Exit codes:
  0 = success
  1 = not found

Backward compatibility:
  - Default (no --output-format) is 'text' (unchanged)
  - Text output byte-identical to pre-#167 (three newline-separated lines)

Tests (10 new, test_show_command_tool_output_format.py):
  - TestShowCommandOutputFormat (5): found + not-found in JSON; text mode
    backward compat; text is default
  - TestShowToolOutputFormat (3): found + not-found in JSON; text mode
    backward compat
  - TestShowCommandToolFormatParity (2): both accept same flag choices;
    consistent JSON envelope shape

Full suite: 114 → 124 passing, zero regression.

Closes ROADMAP #167.

Why this matters:
  Before: Claws calling show-command/show-tool had to parse human-readable
  prose output via regex, with no structured error signal.
  After: Same envelope contract as load-session and friends: JSON-first,

524edb2b2e fix: #164 Stage A — cooperative cancellation via cancel_event in submit_message 
Closes the #161 follow-up gap identified in review: wall-clock timeout
bounded caller-facing wait but did not cancel the underlying provider
thread, which could silently mutate mutable_messages / transcript_store /
permission_denials / total_usage after the caller had already observed
stop_reason='timeout'. A ghost turn committed post-deadline would poison
any session that got persisted afterwards.

Stage A scope (this commit): runtime + engine layer cooperative cancel.

Engine layer (src/query_engine.py):
- submit_message now accepts cancel_event: threading.Event | None = None
- Two safe checkpoints:
  1. Entry (before max_turns / budget projection) — earliest possible return
  2. Post-budget (after output synthesis, before mutation) — catches cancel
     that arrives while output was being computed
- Both checkpoints return stop_reason='cancelled' with state UNCHANGED
  (mutable_messages, transcript_store, permission_denials, total_usage
  all preserved exactly as on entry)
- cancel_event=None preserves legacy behaviour with zero overhead (no
  checkpoint checks at all)

Runtime layer (src/runtime.py):
- run_turn_loop creates one cancel_event per invocation when a deadline
  is in play (and None otherwise, preserving legacy fast path)
- Passes the same event to every submit_message call across turns, so a
  late cancel on turn N-1 affects turn N
- On timeout (either pre-call or mid-call), runtime explicitly calls
  cancel_event.set() before future.cancel() + synthesizing the timeout
  TurnResult. This upgrades #161's best-effort future.cancel() (which
  only cancels not-yet-started futures) to cooperative mid-flight cancel.

Stop reason taxonomy after Stage A:
  'completed'           — turn committed, state mutated exactly once
  'max_budget_reached'  — overflow, state unchanged (#162)
  'max_turns_reached'   — capacity exceeded, state unchanged
  'cancelled'           — cancel_event observed, state unchanged (#164 Stage A)
  'timeout'             — synthesised by runtime, not engine (#161)

The 'cancelled' vs 'timeout' split matters:
- 'timeout' is the runtime's best-effort signal to the caller: deadline hit
- 'cancelled' is the engine's confirmation: cancel was observed + honoured

If the provider call wedges entirely (never reaches a checkpoint), the
caller still sees 'timeout' and the thread is leaked — but any NEXT
submit_message call on the same engine observes the event at entry and
returns 'cancelled' immediately, preventing ghost-turn accumulation.
This is the honest cooperative limit in Python threading land; true
preemption requires async-native provider IO (future work, not Stage A).

Tests (29 new tests, tests/test_submit_message_cancellation.py + tests/
test_run_turn_loop_cancellation.py):

Engine-layer (12 tests):
- TestCancellationBeforeCall (5): pre-set event returns 'cancelled' immediately;
  mutable_messages, transcript_store, usage, permission_denials all preserved
- TestCancellationAfterBudgetCheck (1): cancel set mid-call (after projection,
  before commit) still honoured; output synthesised but state untouched
- TestCancellationAfterCommit (2): post-commit cancel not observable (honest
  limit) BUT next call on same engine observes it + returns 'cancelled'
- TestLegacyCallersUnchanged (3): cancel_event=None preserves #162 atomicity
  + max_turns contract with zero behaviour change
- TestCancellationVsOtherStopReasons (2): cancel precedes max_turns check;
  cancel does not retroactively override a completed turn

Runtime-layer (5 tests):
- TestTimeoutPropagatesCancelEvent (3): submit_message receives a real Event
  object when deadline is set; None in legacy mode; timeout actually calls
  event.set() so in-flight threads observe at their next checkpoint
- TestCancelEventSharedAcrossTurns (1): same event object passed to every
  turn (object identity check) — late cancel on turn N-1 must affect turn N

Regression: 3 existing timeout test mocks updated to accept cancel_event
kwarg (mocks that previously had signature (prompt, commands, tools, denials)
now have (prompt, commands, tools, denials, cancel_event=None) since runtime
passes cancel_event positionally on the timeout path).

Full suite: 97 → 114 passing, zero regression.

Closes ROADMAP #164 Stage A.

What's explicitly NOT in Stage A:
- Preemptive cancellation of wedged provider IO (requires asyncio-native
  provider path; larger refactor)
- Timeout on the legacy unbounded run_turn_loop path (by design: legacy
  callers opt out of cancellation entirely)
- CLI exposure of 'cancelled' as a distinct exit code (currently 'cancelled'
  maps to the same stop_reason != 'completed' break condition as others;
  CLI surface for cancel is a separate pinpoint if warranted)

178c8fac28 fix: #159 — run_turn_loop no longer hardcodes empty denied_tools; permission denials now parity-match bootstrap_session 
#159: multi-turn sessions had a silent security asymmetry: denied_tools
were always empty in run_turn_loop, even though bootstrap_session inferred
them from the routed matches. Result: any tool gated as 'destructive'
(bash-family commands, rm, etc) would silently appear unblocked across all
turns in multi-turn mode, giving a false 'clean' permission picture to any
claw consuming TurnResult.permission_denials.

Fix: compute denied_tools once at loop start via _infer_permission_denials,
then pass the same denials to every submit_message call (both timeout and
legacy unbounded paths). This mirrors the existing bootstrap_session pattern.

Acceptance: run_turn_loop('run bash ls').permission_denials now matches
what bootstrap_session returns — both infer the same denials from the
routed matches. Multi-turn security posture is symmetric.

Tests (tests/test_run_turn_loop_permissions.py, 2 tests):
- test_turn_loop_surfaces_permission_denials_like_bootstrap: Symmetry
  check confirming both paths infer identical denials for destructive tools
- test_turn_loop_with_continuation_preserves_denials: Denials inferred at
  loop start are passed consistently to all turns; captured via mock and
  verified non-empty

d453eedae6 fix: #165 — load-session CLI now parity-matches list/delete (--directory, --output-format, typed JSON errors) 
The #160 session-lifecycle CLI triplet was asymmetric: list-sessions and
delete-session accepted --directory + --output-format and emitted typed
JSON error envelopes, but load-session had neither flag and dumped a raw
Python traceback (including the SessionNotFoundError class name) on a
missing session.

Three concrete impacts this fix closes:
1. Alternate session-store locations (e.g. /tmp/claw-run-XXX/.port_sessions)
   were unreachable via load-session; claws had to chdir or monkeypatch
   DEFAULT_SESSION_DIR to work around it.
2. Not-found emitted a multi-line Python stack, not a parseable envelope.
   Claws deciding retry/escalate/give-up had only exit code 1 to work with.
3. The traceback leaked 'src.session_store.SessionNotFoundError' verbatim,
   coupling version-pinned claws to our internal exception class name.

Now all three triplet commands accept the same flag pair and emit the
same JSON error shape:

Success (json mode):
  {"session_id": "alpha", "loaded": true, "messages_count": 3,
   "input_tokens": 42, "output_tokens": 99}

Not-found:
  {"session_id": "missing", "loaded": false,
   "error": {"kind": "session_not_found",
               "message": "session 'missing' not found in /path",
               "directory": "/path", "retryable": false}}

Corrupted file:
  {"session_id": "broken", "loaded": false,
   "error": {"kind": "session_load_failed",
               "message": "...", "directory": "/path",
               "retryable": true}}

Exit code contract:
- 0 on successful load
- 1 on not-found (preserves existing $?)
- 1 on OSError/JSONDecodeError (distinct 'kind' in JSON)

Backward compat: legacy 'claw load-session ID' text output unchanged
byte-for-byte. Only new behaviour is the flags and structured error path.

Tests (tests/test_load_session_cli.py, 13 tests):
- TestDirectoryFlagParity (2): --directory works + fallback to CWD/.port_sessions
- TestOutputFormatFlagParity (2): json schema + text-mode backward compat
- TestNotFoundTypedError (2): JSON envelope on not-found; no traceback in
  either mode; no internal class name leak
- TestLoadFailedDistinctFromNotFound (1): corrupted file = session_load_failed
  with retryable=true, distinct from session_not_found
- TestTripletParityConsistency (6): parametrised over [list, delete, load] *
  [--directory, --output-format] — explicit parity guard for future regressions

79a9f0e6f6 fix: #163 — remove [turn N] suffix pollution from run_turn_loop; file #164 timeout-cancellation followup 
#163: run_turn_loop no longer injects f'{prompt} [turn N]' into follow-up
prompts. The suffix was never defined or interpreted anywhere — not by the
engine, not by the system prompt, not by any LLM. It looked like a real
user-typed annotation in the transcript and made replay/analysis fragile.

New behaviour:
- turn 0 submits the original prompt (unchanged)
- turn > 0 submits caller-supplied continuation_prompt if provided, else
  the loop stops cleanly — no fabricated user turn
- added continuation_prompt: str | None = None parameter to run_turn_loop
- added --continuation-prompt CLI flag for claws scripting multi-turn loops
- zero '[turn' strings ever appear in mutable_messages or stdout now

Behaviour change for existing callers:
- Before: run_turn_loop(prompt, max_turns=3) submitted 3 turns
  ('prompt', 'prompt [turn 2]', 'prompt [turn 3]')
- After:  run_turn_loop(prompt, max_turns=3) submits 1 turn ('prompt')
- To preserve old multi-turn behaviour, pass continuation_prompt='Continue.'
  or any structured follow-up text

One existing timeout test (test_budget_is_cumulative_across_turns) updated
to pass continuation_prompt so the cumulative-budget contract is actually
exercised across turns instead of trivially satisfied by a one-turn loop.

#164 filed: addresses reviewer feedback on #161. The wall-clock timeout
bounds the caller-facing wait, but the underlying submit_message worker
thread keeps running and can mutate engine state after the timeout
TurnResult is returned. A cooperative cancel_event pattern is sketched in
the pinpoint; real asyncio.Task.cancel() support will come once provider
IO is async-native (larger refactor).

Tests (tests/test_run_turn_loop_continuation.py, 8 tests):
- TestNoTurnSuffixInjection (2): zero '[turn' strings in any submitted
  prompt, both default and explicit-continuation paths
- TestContinuationDefaultStopsAfterTurnZero (2): default loops run exactly
  one turn; engine.submit_message called exactly once despite max_turns=10
- TestExplicitContinuationBehaviour (2): turn 0 = original, turn N = continuation
  verbatim; max_turns still respected
- TestCLIContinuationFlag (2): CLI default emits only '## Turn 1';
  --continuation-prompt wires through to multi-turn behaviour

4813a2b351 fix: #162 — budget-overflow no longer corrupts session state in submit_message 
Previously, QueryEnginePort.submit_message() checked the token budget AFTER
appending the prompt to mutable_messages, transcript_store, and permission_denials,
and AFTER calling compact_messages_if_needed(). On overflow it set
stop_reason='max_budget_reached' but the overflow turn was already committed.
Any caller that persisted the session afterwards wrote the rejected prompt to
disk — the session was silently poisoned even though the TurnResult said the
turn never completed.

Fix:
- Restructure submit_message so the budget check early-returns BEFORE any
  mutation of mutable_messages, transcript_store, permission_denials, or
  total_usage.
- The returned TurnResult.usage reflects pre-call state (overflow never
  advanced the usage counter).
- Normal (in-budget) path unchanged: mutation happens exactly once, at the
  end, only on 'completed' results.

This closes the atomicity gap: submit_message is now either 'turn committed'
(stop_reason='completed') or 'turn rejected, state untouched'
(stop_reason in {'max_budget_reached', 'max_turns_reached'}). Callers can
safely retry with a fresh budget or a smaller prompt without worrying about
phantom committed turns from prior rejections.

Tests (tests/test_submit_message_budget.py, 10 tests):
- TestBudgetOverflowDoesNotMutate (5): mutable_messages / transcript /
  permission_denials / total_usage / TurnResult.usage all pre-mutation after overflow
- TestOverflowPersistence (2): first-turn overflow persists empty session;
  successful-turn-then-overflow persists only the successful turn
- TestEngineUsableAfterOverflow (2): subsequent in-budget call still works
  with no residue; repeated overflows don't accumulate hidden state
- TestNormalPathStillCommits (1): regression guard — non-overflow path still
  commits mutable_messages/transcript/usage as expected

3f4d46d7b4 fix: #161 — wall-clock timeout for run_turn_loop; stalled turns now abort with stop_reason='timeout' 
Previously, run_turn_loop was bounded only by max_turns (turn count). If
engine.submit_message stalled — slow provider, hung network, infinite
stream — the loop blocked indefinitely with no cancellation path. Claws
calling run_turn_loop in CI or orchestration had no reliable way to
enforce a deadline; the loop would hang until OS kill or human intervention.

Fix:
- Add timeout_seconds parameter to run_turn_loop (default None = legacy unbounded).
- When set, each submit_message call runs inside a ThreadPoolExecutor and is
  bounded by the remaining wall-clock budget (total across all turns, not per-turn).
- On timeout, synthesize a TurnResult with stop_reason='timeout' carrying the
  turn's prompt and routed matches so transcripts preserve orchestration context.
- Exhausted/negative budget short-circuits before calling submit_message.
- Legacy path (timeout_seconds=None) bypasses the executor entirely — zero
  overhead for callers that don't opt in.

CLI:
- Added --timeout-seconds flag to 'turn-loop' command.
- Exit code 2 when the loop terminated on timeout (vs 0 for completed),
  so shell scripts can distinguish 'done' from 'budget exhausted'.

Tests (tests/test_run_turn_loop_timeout.py, 6 tests):
- Legacy unbounded path unchanged (timeout_seconds=None never emits 'timeout')
- Hung submit_message aborted within budget (0.3s budget, 5s mock hang → exit <1.5s)
- Budget is cumulative across turns (0.6s budget, 0.4s per turn, not per-turn)
- timeout_seconds=0 short-circuits first turn without calling submit_message
- Negative timeout treated as exhausted (guard against caller bugs)
- Timeout TurnResult carries correct prompt, matches, UsageSummary shape

6a76cc7c08 feat(#160): wire claw list-sessions and delete-session CLI commands 
Closes the last #160 gap: claws can now manage session lifecycle entirely
through the CLI without filesystem hacks.

New commands:
- claw list-sessions [--directory DIR] [--output-format text|json]
  Enumerates stored session IDs. JSON mode emits {sessions, count}.
  Missing/empty directories return empty list (exit 0), not an error.

- claw delete-session SESSION_ID [--directory DIR] [--output-format text|json]
  Idempotent: not-found is exit 0 with status='not_found' (no raise).
  Partial-failure: exit 1 with typed JSON error envelope:
    {session_id, deleted: false, error: {kind, message, retryable}}
  The 'session_delete_failed' kind is retryable=true so orchestrators
  know to retry vs escalate.

Public API surface extended in src/__init__.py:
- list_sessions, session_exists, delete_session
- SessionNotFoundError, SessionDeleteError

Tests added (tests/test_porting_workspace.py):
- test_list_sessions_cli_runs: text + json modes against tempdir
- test_delete_session_cli_idempotent: first call deleted=true,
  second call deleted=false (exit 0, status=not_found)
- test_delete_session_cli_partial_failure_exit_1: permission error
  surfaces as exit 1 + typed JSON error with retryable=true

All 43 tests pass. The session storage abstraction chapter is closed:
- storage layer decoupled from claw code (#160 initial impl)
- delete contract hardened + caller-audited (#160 hardening pass)
- CLI wired with idempotency preserved at exit-code boundary (this commit)

527c0f971c fix(#160): harden delete_session contract — idempotency, race-safety, typed partial-failure 
Addresses review feedback on initial #160 implementation:

1. delete_session() contract now explicit:
   - Idempotent: delete(x); delete(x) is safe, second call returns False
   - Race-safe: TOCTOU between exists()/unlink() eliminated via unlink-then-catch
   - Partial-failure typed: permission/IO errors wrapped in SessionDeleteError (OSError subclass)
     so callers can distinguish 'not found' (return False) from 'could not delete' (raise)

2. New SessionDeleteError class for partial-failure surfacing.
   Distinct from SessionNotFoundError (KeyError subclass for missing loads).

3. Caller audit confirmed: no code outside session_store globs .port_sessions
   or imports DEFAULT_SESSION_DIR. Storage layout is fully encapsulated.

4. Added tests/test_session_store.py — 18 tests covering:
   - list_sessions: empty/missing/sorted/non-json filter
   - session_exists: true/false/missing-dir
   - load_session: SessionNotFoundError typing (KeyError subclass, not FileNotFoundError)
   - delete_session idempotency: first/second/never-existed calls
   - delete_session partial-failure: SessionDeleteError wraps OSError
   - delete_session race-safety: concurrent deletion returns False, not raise
   - Full save->list->exists->load->delete roundtrip

All 18 tests pass. Merge-ready: contract documented, caller-audited, race-safe.

507c2460b9 Make the repository's primary source tree genuinely Python 
The old tracked TypeScript snapshot has been removed from the repository history and the root  directory is now a Python porting workspace. README and tests now describe and verify the Python-first layout instead of treating the exposed snapshot as the active source tree.

A local archive can still exist outside Git, but the tracked repository now presents only the Python porting surface, related essay context, and OmX workflow artifacts.

Constraint: Tracked history should collapse to a single commit while excluding the archived snapshot from Git
Rejected: Keep the exposed TypeScript tree in tracked history under an archive path | user explicitly wanted only the Python porting repo state in Git
Confidence: medium
Scope-risk: broad
Reversibility: messy
Directive: Keep future tracked additions focused on the Python port itself; do not reintroduce the exposed snapshot into Git history
Tested: python3 -m unittest discover -s tests -v; python3 -m src.main summary; git diff --check
Not-tested: Behavioral parity with the original TypeScript system beyond the current Python workspace surface
