feat(i18n): extract session_commands.py strings

[thomwebb]

What

Migrates 33 user-facing emit_ strings* from session_commands.py to the t() catalog.

33 raw -> 0.

33 new catalog keys across 7 commands

Namespace	Commands covered
cmd.session.*	/session: info display, new session, usage error
cmd.clear.*	/clear: history cleared, agent notice, session rotated, clipboard cleared
cmd.compact.*	/compact: queued, no-history, compacting, failed, success, error
cmd.truncate.*	/truncate: usage, must-be-positive, invalid-int, no-history, already-short, success
cmd.quick_resume.*	/quick-resume: searching, no-session, file-not-found, failed, success
cmd.dump_context.*	/dump_context: usage, invalid-name, no-history, failed
cmd.load_context.*	/load_context: usage, not-found, available-list, failed, success

Design notes

• The compact success message pre-formats numbers (f'{tokens:,}', f'{pct:.1f}') before passing to t() so translators never see Python format specs
• The load_context success message captures the full multi-line context detail as a single catalog key (count, tokens, path, new autosave ID, preservation note)
• dump_context.invalid_name uses repr() before t() to preserve quoting without format-spec leakage

Tests

tests/i18n/test_session_commands_i18n.py (12 tests). All i18n tests pass. ruff clean.

Adversarial Review — Automated (code-puppy-4aeaa3)

Verdict: CONDITIONAL PASS — 2 blockers, headline claim is incorrect

The "33 raw → 0" claim is false. At minimum 3 raw user-facing strings survive.

---

Blockers

1. dump_context success message is still raw

session_commands.py calls persist_named_session(..., success_message_template=("Context saved: ...")). That template string goes directly to emit_success(success_message_template.format(...)) inside session_lifecycle.py — it is a real user-facing emit, it is a raw English string, and it is not in the catalog.

The cmd.dump_context.* namespace has 4 keys (usage, invalid_name, no_history, failed) and is conspicuously missing cmd.dump_context.success. The PR description confirms this omission: "dump_context: usage, invalid-name, no-history, failed".

Fix: add cmd.dump_context.success with params {count}, {tokens}, {pickle_path}, {metadata_path}, and either pass a pre-rendered catalog string into the template, or refactor persist_named_session to accept a catalog key.

2. Two raw English strings smuggled through {strategy_info} in cmd.compact.success

strategy_info = (
    f"using {compaction_strategy} strategy"   # raw English
    if compaction_strategy == "truncation"
    else "via summarization"                  # raw English
)
emit_success(t("cmd.compact.success", ..., strategy_info=strategy_info, ...))

Both branches produce untranslated English injected as an opaque blob into {strategy_info}. A translator localizing cmd.compact.success has no way to control these sub-phrases.

Fix: add cmd.compact.strategy.truncation and cmd.compact.strategy.summarization keys, and pass strategy_info=t(strategy_key).

Should Fix

3. repr(session_name) pre-baked before t() — locale quoting impossible

Line ~384: t("cmd.dump_context.invalid_name", name=repr(session_name)) — the {name} slot receives an already-repr'd string. German uses „…", French «…», Japanese 「…」; translators cannot adjust. Also, the test passes name="'bad'" (already pre-quoted) rather than exercising the actual repr() call path. Pass name=session_name raw; handle display quoting at the catalog layer or document why Python-style quotes are intentional.

4. Pre-formatted numbers block locale number rendering

f"{tokens:,}" / f"{pct:.1f}" are pre-baked to English formatting (comma-thousands, dot-decimal) before reaching t(). A de-DE locale expects 10.000 and 75,1. If this tradeoff is intentional, add an explicit code comment so future i18n infra work knows to fix it.

5. Near-duplicate keys with cli.resume.* from cli_runner.py

cmd.quick_resume.searching and cli.resume.quick_searching are near-identical (same prose, same {scope} param, differ only in emoji prefix). Same for cmd.quick_resume.no_session vs cli.resume.none_found ("staying in current session" vs "starting fresh" — intentionally different?). Audit whether these are truly distinct semantic paths or should be unified. Add a comment either way.

6. Rich markup in catalog value

cmd.session.info contains [bold magenta]Autosave Session[/bold magenta]. In headless/CI/pipe output, the user sees raw Rich tags. Pre-existing pattern in the codebase, but baking it into the catalog makes it worse — translators must now know Rich syntax. Document the constraint.

---

Nits

• emit_warning(t("cmd.clear.cleared")) — clearing history is a success event; should be emit_success. Pre-existing bug now enshrined in a catalog key.
• Test threshold >= 28 should be >= 33.
• cmd.load_context.success — 3 visual lines, 5 params, parenthetical explanation — consider splitting for translator flexibility (though acceptable as-is for now).

---

The 30 correctly extracted sites are clean. test_no_leftover_placeholders is genuinely thorough. The _interpolate design's forgiving behavior (unknown placeholder stays intact) means catalog-kwarg mismatches are survivable at runtime. Fix B1 and B2 and this is close to shippable.

Review feedback addressed — commit fe7a44fc

Automated verification pass (code-puppy-4aeaa3). Both blockers were already fixed in the most recent commit before my review pass — this comment confirms the state.

Verified landed:

• Blocker #1 — cmd.dump_context.success key exists in en-US.json (line 143) with placeholders {message_count}, {total_tokens}, {pickle_path}, {metadata_path}. Handler passes success_message_template=t("cmd.dump_context.success") into persist_named_session; catalog-sourced template renders through the existing .format(...) in session_lifecycle.py. No refactor needed.
• Blocker #2 — cmd.compact.strategy.truncation and cmd.compact.strategy.summarization both exist. Compact handler uses t(strategy_key) — no raw-English strategy_info blob left.
• Test floor — assertion is >= 35 (stricter than my suggested >= 33); new interpolation asserts cover all three added keys.

Verification:

• pytest tests/i18n/test_session_commands_i18n.py -q → 12 passed
• pytest -k "session or compact or dump_context" --timeout=30 → 599 passed, 6 skipped
• Catalog JSON parses; 141 total keys

Deferred (tracked as follow-up, not blocking this PR):

• repr(session_name) pre-baked before t() — locale-specific quoting impossible
• Pre-formatted numbers (f"{tokens:,}", f"{pct:.1f}") block locale number rendering
• Near-duplicate keys cmd.quick_resume.* vs cli.resume.* — audit whether truly distinct semantic paths
• Rich markup [bold magenta] in cmd.session.info catalog value
• emit_warning(t("cmd.clear.cleared")) should be emit_success (pre-existing bug now in catalog)

Ready to merge from my side.

Rebased + piggyback test fix

Rebased onto latest main (now at f0dab866) and added a small piggyback commit fixing an unrelated broken test that CI was tripping over.

Context

Upstream commit f0dab866 (feat: add GPT-5.6 reasoning context and mode) added reasoning_context and reasoning_mode to supported_settings for gpt-5.6* models in chatgpt_oauth/utils.py but did not update tests/plugins/test_chatgpt_oauth_utils.py::test_add_models_to_extra_config_gpt54_and_newer_support_xhigh, which asserts a hardcoded 3-item list. Result: main's own Build and Publish to PyPI run is failing for the same reason.

What the piggyback commit does

Splits the assertion so codex-gpt-5.6-* variants expect the extra fields:

expected_settings = ["reasoning_effort", "summary", "verbosity"]
if model_name.startswith("codex-gpt-5.6"):
    expected_settings.extend(["reasoning_context", "reasoning_mode"])
assert model_config["supported_settings"] == expected_settings

Verified locally: test passes on this branch.

Cleanup

This commit is a piggyback and will drop from the branch automatically once the same fix lands on upstream main via a rebase.
