Follow-up per independent review of #68633 (GPT-5.6-sol-xhigh in Codex,
reviewer egilewski) on this PR.
Two real bugs in the blank-text-block filtering added by that fix:
1. `effective = blocks or content` fell back to the RAW, unfiltered
`content` variable whenever every block was filtered out as blank --
which happens precisely when the entire message content WAS the
blank/whitespace payload the filter exists to remove (a sole blank
text block, a sole cache-marked blank block, or standalone
whitespace scalar content with no tool_calls). The fallback silently
restored the exact invalid content the filtering just stripped,
leaving the message provider-invalid.
Fixed: `effective = blocks if blocks else [{"type": "text", "text":
"(empty)"}]` -- never falls back to raw `content`. Also moved the
cache_control application (both the relocated-from-a-dropped-block
marker and the message-level marker) to run against `effective`
instead of the pre-fallback `blocks`, so a cache marker on a block
that was the ONLY content still lands on the (empty) placeholder
rather than being silently lost when `blocks` was empty at the
point it would otherwise have been applied.
2. The normal-path blank-text check used `(blk.get("text") or "").strip()`,
which is not type-safe for a truthy NON-string, non-None text value
(e.g. an int or dict from an invalid upstream payload) -- `or`
doesn't substitute for a truthy value, so `(7 or "").strip()` still
raises AttributeError. Now checks `isinstance(text, str)` first,
matching the replay path's `_sanitize_replay_block()`, which the
reviewer confirmed was already correctly type-safe.
Added regression tests for: sole blank list block, sole whitespace
scalar content, sole cache-marked blank block (marker relocation to
the placeholder), a truthy non-string (int) text value both mixed with
a surviving tool_use and as the sole content, and a dict-valued text
field. 7/7 new tests pass; 193/193 in the full
tests/agent/test_anthropic_adapter.py file; 23/23 in
tests/agent/test_prompt_caching.py (unaffected, confirmed).
Ports #63228 forward onto current main per teknium1's review.
Bedrock and strict Anthropic-compatible endpoints reject text blocks
where text is empty or whitespace-only with HTTP 400. The normal
list-content path extended blocks without filtering, and the
ordered-replay fast path (_sanitize_replay_block) returned blank text
blocks unfiltered.
Per review, fixes three gaps in the original port:
1. Type safety: the normal-path filter used blk.get('text', '').strip(),
which crashes with AttributeError when text is explicitly None (not
absent) -- .get()'s default only applies when the key is missing.
_convert_content_part_to_anthropic() can preserve None from an
invalid upstream input text block. Now uses
(blk.get('text') or '').strip() on both paths.
2. Cache marker loss: prompt_caching.py's _apply_cache_marker() sets
cache_control directly on content[-1] for list content. If that last
part happens to be blank text, dropping it without relocating
cache_control silently loses the breakpoint. Both the normal and
replay paths now capture a dropped block's cache_control and reapply
it to the new last surviving cacheable block via the existing
_apply_assistant_cache_control_to_last_cacheable_block() helper
(setdefault semantics, so it never clobbers a legitimately-placed
marker).
3. Scalar whitespace: the non-list content branch
(blocks.append({'type': 'text', 'text': str(content)})) accepted a
truthy whitespace-only string unfiltered. Now filtered the same way
as list-content blocks.
8/8 new tests pass in TestBlankTextBlockFiltering (including None-safety,
scalar-whitespace, and cache_control-relocation regressions on both
paths); 186/186 in the full tests/agent/test_anthropic_adapter.py file.
OpenAI documents GPT-5.5 / GPT-5.5 Pro as extended-cache-only: in-memory
prompt cache retention is not available for them, and only
prompt_cache_retention: "24h" is supported. Responses requests that omit
the field see near-zero cached_tokens even with a stable prompt_cache_key
and identical prefixes (observed on an OpenAI-compatible Responses relay:
0 cached across repeated identical calls before; 97% cache reads after).
Send the field for the gpt-5.5 model family (bare and namespaced ids like
openai.gpt-5.5) on OpenAI-compatible Responses routes, mirrored in the
auxiliary Codex adapter, and pass it through preflight normalization.
Skipped for xAI, GitHub/Copilot, and the chatgpt.com Codex backend, which
reject or ignore body-level cache fields.
A brew Python upgrade (original report) or an interrupted venv rebuild
(v0.19.0 report in the same thread) can leave certifi importable while
its bundled cacert.pem is missing or a dangling symlink. Every TLS
connection then fails — Feishu/Telegram/WeChat/DingTalk all down —
with an opaque 'Could not find a suitable TLS CA certificate bundle'
from deep inside httpx/requests.
The existing repair infrastructure only probed
`hasattr(certifi, 'contents')`, which PASSES in exactly this failure
state, so neither the early venv self-heal nor `hermes update`'s
import-probe repair ever classified certifi as broken. Extended, not
replaced:
- hermes_cli/_early_recovery.py: the in-process probe now also
validates that certifi.where() exists and is a plausible bundle
(>=1KiB), so the pre-import self-heal repairs it like any other
wiped core package.
- hermes_cli/main.py (_detect_broken_lazy_refresh_imports): the
subprocess probe script used by `hermes update`'s venv repair
applies the same bundle-file check inside the target venv.
- hermes_cli/doctor.py: `hermes doctor` already failed the cert
check; `hermes doctor --fix` now repairs it (pip force-reinstall
certifi + module-cache invalidation + re-verify), covering
brew/manual venvs where no update marker exists. Failures funnel
into the manual-action list with the exact command.
- agent/ssl_guard.py: the startup SSLConfigurationError hint now leads
with `hermes doctor --fix` instead of only the raw pip command.
Fixes#29866
Running any state-writing `hermes cron` CLI command as root (the
default for `docker exec`) rewrote jobs.json via mkstemp +
atomic_replace, leaving it root:root mode 600. The gateway's ticker
(uid 1000 via PUID/PGID) was then locked out of every tick with
PermissionError — silently: the liveness heartbeat stayed fresh,
`hermes cron status` opened with 'Gateway is running — cron jobs will
fire automatically', and in the field ~14h of scheduled jobs were
skipped before a human noticed the absence of messages.
Fixes, per the issue's suggested items 1 and 3:
1. Ownership preservation on save (cron/jobs.py): snapshot the owner
before the atomic replace; when the writer is privileged (euid 0)
and the previous owner differs, chown the rewritten file back.
First-time creation inherits the cron dir's owner. Unprivileged
writers never call chown. POSIX-only (guarded via os.name/getattr),
best-effort — a chown failure logs a warning but never breaks the
save. 0600 hardening is unchanged.
2. Zombie-ticker surfacing: the ticker loop (both single-profile and
multiplex paths) now persists the failure reason to a
ticker_last_error marker next to the heartbeat files on every
failed tick, and clears it on the next clean tick. `hermes cron
status` shows the recorded reason in its 'ticks may be failing'
branch, plus an actionable ownership hint when the error is a
PermissionError (recommend `docker exec -u <uid>:<gid>`).
Fixes#68483
ACP clients (Zed, Buzz) render the whole availableModels array in a single
dropdown, so requesting the shared inventory with max_models=None could
hand an editor an unbounded cross-provider catalog.
Request the same per-provider cap the MoA picker already uses
(hermes_cli/moa_cmd.py), exposed as ACP_MAX_MODELS_PER_PROVIDER so the
intent is documented at the call site.
This bounds each provider's row rather than the total, matching the shared
inventory's own semantics: aggregator providers stay intentionally
uncapped, and the existing current-model fallback still re-inserts a
selection that falls outside the cap. At present no authenticated provider
approaches 200 models, so the visible catalog is unchanged; the cap is a
guardrail for large catalogs (e.g. OpenRouter) rather than a change to
today's lists.
The new test asserts the contract - bounded row plus a reachable current
selection - instead of a fixed catalog size, so growing the inventory
cannot turn it into a change-detector.

When api_key_hint from a 401 response doesn't match any pool entry
(common with OAuth tokens where runtime_api_key rotates), the pool
rotated without marking anything exhausted and handed back a fresh
selection. Because nothing was ever marked, the pool could never reach
the "no available entries" state — the caller retried the same dead
token forever (~6 attempts/sec), starving the event loop so /stop was
never processed; only killing the gateway ended it.
Rebased onto the identity-tracking rework that landed on main
(73c4b5a045): the single-entry escape from that commit already stops
the most common OAuth case, so this fix bounds the REMAINING gap —
multi-entry pools ping-ponging A->B->A with an unmatched hint. Cap
consecutive no-mark rotations at one full lap of the available
entries, then return None so the error surfaces / fallback activates.
Deliberately does NOT mark innocent entries exhausted (the original
PR's approach): that would quarantine a healthy key for the full
cooldown TTL on a hint that provably matches nothing. No cooldown is
written by the escape, so healthy keys stay available next turn --
bounded without hammering.
The streak resets when a rotation identifies a real entry and on any
successful normal select(), so only genuinely consecutive unmatched
rotations trip the bound.
Fixes#70401
Follow-up on the #69500 salvage: 'launchctl submit' jobs remain
registered with launchd after they exit, so every plist reload leaked
one dead '<label>.reload.<pid>.<ts>' label. The helper script now ends
with 'launchctl remove' of its own transient label, and the recovery
test asserts the self-removal is present.
The deferred launchd reload helper used start_new_session=True to detach
from the gateway's process group. However, setsid(2) alone does NOT move
the child outside the launchd job's process coalition — when launchctl
bootout fires on the gateway label, launchd terminates ALL processes in
that coalition, including the setsid-detached helper, leaving the service
permanently unloaded.
Fix by spawning the helper via launchctl submit, which creates a
transient launchd one-shot job that is wholly independent of the
gateway's coalition. This ensures the helper survives bootout and can
complete the bootstrap+verify cycle.
Also writes a durable pre-bootout marker to the reload log so the
distinction between 'helper never started' and 'helper ran but
bootout/bootstrap failed' can be diagnosed.
Fixes#69098
Hardening follow-up to the #69619 review fix. The previous regression
byte-pinned only the rescued pre-#69619 generation; older frozen entries
were covered solely by fragment assertions and a self-matching loop that
cannot detect a frozen entry mutating (the loop tests each entry against
itself).
- Pin all four _HISTORICAL_SUMMARY_PREFIXES generations as literals in
_FROZEN_PREFIX_GENERATIONS and assert order-sensitive tuple equality
plus detect/strip for each
- State the prepend-only contract explicitly on the tuple: never mutate
or reorder existing entries
Negative controls verified: mutating, dropping, or reordering a frozen
entry each fail the new test, while the legacy self-matching loop still
passes under mutation — confirming the closed coverage gap.
Address review on #69619: the previous commit mutated the newest frozen
entry in _HISTORICAL_SUMMARY_PREFIXES and never froze the live prefix it
retired (the generation with both the four-heading discard clause and
the tools-active clause). A summary persisted immediately before
upgrading was therefore treated as an ordinary message on
resume/re-compaction, keeping the old handoff text embedded in the body.
- Prepend the exact pre-change live prefix as a new frozen entry
(newest-first), leaving all existing frozen entries byte-identical
- Restore the Jul 2026 (#65848 class) frozen entry to its original
four-heading text
- Pin the retired generation as a literal in
test_summary_prefix_semantics.py so mutating or dropping it fails CI
- Make the #65848 tool-use regression position-agnostic (match the
pre-clause generation by content, not tuple index)
Verified byte-identity of both rescued generations against the parent
commit. 233 focused prefix/resume/compressor tests pass.
Remove three directive-heavy section headers from both the LLM
and deterministic summary templates that caused the agent to
resume stale tasks after context compression:
- Historical In-Progress State
- Historical Pending User Asks
- Historical Remaining Work
These sections read as actionable instructions even within a
REFERENCE-ONLY wrapper, hijacking the user's latest message.
The remaining sections are purely descriptive/past-tense.
Frozen prefix copies in _HISTORICAL_SUMMARY_PREFIXES updated
to match. Test 8/8 passed.
Two gaps found auditing the decode-crash cluster:
1. suppress_platform_ver_console() only ran in hermes_cli.main processes;
slash workers, tui_gateway/entry, run_agent, batch_runner, and cli.py
import only hermes_bootstrap and were exposed to both the console
flash and (on Python 3.11.0/3.11.1, which lack CPython's
encoding='locale' fix) a UnicodeDecodeError inside platform.win32_ver()
under PEP 540 — the crash #69413 reported. Move the stub into
hermes_bootstrap so every entry point gets it; the _subprocess_compat
copy stays for non-bootstrap callers.
2. The desktop Electron spawn built the backend env without PYTHONUTF8,
so anything the Python child emitted before hermes_bootstrap ran
(interpreter startup errors, pre-bootstrap tracebacks) decoded with
the locale default. Re-port of PR #56499's env half (echoriver89) to
backend-env.ts (original targeted the deleted backend-env.cjs);
explicit user setting wins.
Follow-up to the salvaged #38985: guard the 4 bare read_text/write_text
sites its allowlist missed (google_chat thread-count store + oauth JSON)
and add whatsapp/google_chat to the AST guard test's file list.
On Windows, pipe I/O can deliver non-UTF-8 bytes at chunk boundaries,
causing `UnicodeDecodeError` when the MCP SDK's `TextReceiveStream`
uses `errors="strict"`. Set `encoding_error_handler="replace"` on
`StdioServerParameters` so undecodable bytes become U+FFFD instead
of crashing.
Add a persisted, backend-confirmed provider/model lock for Hermes
Browser and other session API clients. A confirmed lock is an
execution contract rather than response metadata:
- POST /api/sessions/{session_id}/model validates and persists a
confirmed browser_model_lock (advertised in /v1/capabilities)
- session chat + chat/stream consume the persisted lock on body-only
follow-up turns; a confirmed lock wins over an older gateway session
/model override and the session-persisted model
- a later successful session /model switch explicitly clears and
replaces the lock while preserving lineage markers (_branched_from)
and invalidating cached system-prompt model/provider metadata
- ordinary one-off request overrides never replace a confirmed lock
- provider-resolution failure fails closed as a typed provider-auth
error (controlled response, never global-credential reuse)
- confirmed locks disable the global fallback model chain
- the completed agent's actual provider/model must match the locked
route or the turn fails with a runtime-mismatch error
- responses carry sanitized runtime metadata reporting actual vs
requested provider/model and lock state
Rebased onto the provider-aware request routing (#70853) and
session-model parity (#70931) that landed since the original branch;
the lock now slots into that precedence chain as the top rung.
Salvaged from PR #61236 by @abundantbeing.
Three parity fixes between the API server and the native gateway's
agent-runtime resolution, integrated with the provider-aware request
routing that landed in #70853:
- Session-persisted model is honored: POST /api/sessions {"model": ...}
stores a model that the chat handlers previously fetched and threw
away. A stored value that matches a model_routes alias goes through
the route path (route provider/credentials apply); a raw model string
threads through as session_model, pinning the session's turns ahead
of per-request body values but below an explicit session /model
override.
- Empty-model recovery: provider-catalog default when config has no
model.default but a provider resolved, plus last-known-good model
recovery (#35314) keyed on gateway_session_key only (never ephemeral
session_id — no unbounded growth from one-off requests).
- Provider auth failures surface as controlled responses: RuntimeError
from _resolve_runtime_agent_kwargs() is re-raised as a dedicated
_ProviderAuthResolutionError at the call site, caught narrowly in
_run_agent() and the /v1/runs executor to return run.py's response
shape instead of an undifferentiated 500 (session-chat endpoints
previously returned a raw aiohttp 500 with no JSON body).

cron/scheduler.py deliberately applies utf-8/replace only on Windows via
popen_kwargs (non-Windows keeps locale default per its test contract) —
drop the sweep's unconditional inline kwargs there. Update the gateway
force-kill kwarg snapshot for the new guard.
- whatsapp taskkill + webhook gh-comment assert_called_with: add the two
new kwargs
- test_status fake_run: accept **kwargs so signature-strict stub doesn't
TypeError on encoding/errors
- Strip the salvaged commit's inline encoding kwargs where main had since
gained its own (process_registry, local env, cua doctor, gateway,
commands, gateway_windows — the latter keeps its locale-aware
_schtasks_encoding() from #38186)
- Revert encoding kwargs mistakenly applied to non-subprocess APIs
(exa get_contents, tempfile.mkstemp in webhook.py)
- Guard the ddgs worker Popen (new on main since #55339)
- Update two kwarg-snapshot test assertions for the new kwargs
Adds a new rule to scripts/check-windows-footguns.py that flags
subprocess.run/Popen/call/check_output/check_call(..., text=True, ...) calls
missing an explicit encoding= kwarg.
On Chinese Windows (cp936/GBK) and other non-UTF-8 default codepages,
text=True without encoding= decodes child output with
locale.getpreferredencoding(False), crashing _readerthread with
UnicodeDecodeError on non-default-codepage bytes (issues #47939, #53428,
rule prevents future regressions.
Rule design:
- Pattern matches 'text=True' / 'text = True'
- post_filter skips lines that:
- already pass encoding= on the same line
- are method definitions (def text)
- contain text=True inside string literals
- are not subprocess-shaped calls (heuristic via _is_likely_subprocess_call)
- Two helper functions: _is_likely_subprocess_call, _looks_like_string_literal
- Multi-line calls where subprocess.X( and text=True are on different lines
are not flagged (acceptable false negative for a line-based scanner)
Also fixes the linter's own footgun: get_staged_files() and get_diff_files()
used subprocess.check_output(text=True) without encoding= — now fixed.
Suppresses 4 false positives on non-Windows platform-exclusive calls:
- tools/voice_mode.py (Termux/Android)
- tools/environments/singularity.py (Linux HPC)
- plugins/google_meet/cli.py (macOS system_profiler)
Test plan:
- 21 unit tests in tests/scripts/test_footgun_subprocess_encoding.py
- TestDetection: 6 cases verifying the rule flags real subprocess calls
- TestSuppression: 7 cases verifying false-positive avoidance
- TestHelpers: 7 cases for the two helper functions
- TestFullRepoScan: scans the whole tree and asserts the new rule finds
only the 7 call sites that PR #60741 fixes (or zero, once #60741 merges)
Verified: full-repo scan reports 7 matches on main (the #60741 sites),
4 platform-exclusive calls correctly suppressed, zero false positives.
Hermes-sweeper review on #60741 flagged that _op_version (the paired
op probe used by the same setup/status CLI flow at lines 127 and 205)
still ran text=True without explicit encoding/errors.
Add encoding='utf-8', errors='replace' to match _op_whoami and the
production op read path at agent/secret_sources/onepassword.py:271-278.
Also extend the regression test to cover _op_version alongside
_op_whoami, and update the module docstring to reflect the widened
scope. Test sensitivity verified: reverting the source change makes
test_op_version_passes_utf8_encoding fail with encoding=None.
PR #55339 adds encoding='utf-8', errors='replace' to 26 subprocess.run(text=True)
call sites across the codebase. The triage review (thanks @alt-glitch) diffed
this PR against #55339 and found that 5 of the 6 originally-touched call sites
are already covered there byte-identically:
- hermes_cli/main.py::_probe_container
- hermes_cli/setup.py SSH probe
- tools/tts_tool.py::_generate_neutts
- tools/transcription_tools.py::_prepare_local_audio
- tools/transcription_tools.py::_transcribe_local_command (both branches)
The one genuinely net-new site — hermes_cli/onepassword_secrets_cli.py::_op_whoami
(the 1Password op CLI whoami probe) — is NOT in #55339 and is fixed here.
Without explicit encoding=, text=True decodes child output with
locale.getpreferredencoding(False) — cp936 on Chinese Windows — which crashes
_readerthread on non-GBK bytes, cascading into pipe buffer fills, event loop
stalls, and TUI freezes (issues #47939, #53428, #57238).
Scope narrowed per triage feedback: the other 5 sites should land via #55339.

Add authenticated GET /api/model/options to the gateway API server,
sharing the dashboard/TUI picker payload builder so external clients
can sync to the user's configured Hermes provider catalog instead of
scraping the single OpenAI-compatible /v1/models alias.
- new shared hermes_cli.inventory.build_model_options_payload() wraps
build_models_payload with the stable picker shape and safe
custom-provider probe policy (probe current only on normal open,
probe all + cache bust on explicit refresh)
- dashboard web_server and TUI gateway model.options refactored onto
the shared builder; dashboard build moved off the event loop via
run_in_threadpool
- capabilities endpoint advertises model_options
- docs for both API server and programmatic integration

Follow-up to salvaged PR #70549:
- Replace fragile 'or' assertions with single precise checks that catch
partial-rewrite regressions (would have masked a missing closing brace)
- Add test_pty_path_uses_rewritten_command covering the PTY spawn path
that was modified but previously untested
A session pinned to a named custom provider could silently reroute to the
user's default provider on resume/rebuild. Session rows persist the RESOLVED
provider — bare "custom" for every named providers:/custom_providers: entry —
and when no base_url survived in model_config, the existing heal
(canonical_custom_identity) had only the config.model.provider fallback left.
For users whose global default is a BUILT-IN provider (e.g. nous) that tier
cannot fire, so the bare provider was dropped, resume fell back to the default
provider with the session's custom model name, and the default endpoint 404'd
with "Model '<x>' not found. The requested model does not exist in our
configuration or OpenRouter catalog." Re-selecting via /model fixed it until
the next resume — the reported symptom.
Add a model-name recovery tier between the base_url reverse-lookup and the
config fallback: find_custom_provider_identity_by_model() maps the stored
model back to the entry that serves it (model/default_model/models catalog,
dict and legacy list shapes). The session row always stores the model, so the
entry identity survives even when the row has no base_url AND the global
default points elsewhere.
All five bare-custom heal sites in tui_gateway/server.py now pass the model:
_ensure_session_db_row, _stored_session_runtime_overrides,
_runtime_model_config, _make_agent, and _model_picker_context.
Issue #68915: when the agent runs a compound command with trailing & (e.g.
`cd /app && node server.js &`), bash parses it as `(A && B) &` — a subshell
that holds the stdout pipe open forever when B is a long-running server.
The existing _rewrite_compound_background in terminal_tool.py correctly
rewrites this to `A && { B & }` to avoid the subshell fork, but it was only
applied in the foreground execute() path (tools/environments/base.py).
The background spawn_local() path bypasses base.py entirely and passed the
raw command directly to Popen/PTY, leaving the deadlock unmitigated.
Fix: apply _rewrite_compound_background in spawn_local() before the command
is passed to Popen or PTY spawn. Uses a lazy import to avoid circular
dependency (terminal_tool imports process_registry).
- PTY spawn path: now uses safe_command (rewritten)
- Popen spawn path: now uses safe_command (rewritten)
- Session.command still stores the original (unrewritten) command for display
- Simple `cmd &` is left unchanged (no subshell bug)
Tests: 4 regression tests verifying (1) compound is rewritten, (2) simple bg
is preserved, (3) multi-line compounds are rewritten, (4) session.command
stores original.
Follow-up on the salvaged #68469 commit:
- Literal-IP hostnames never take the proxy DNS-delegation path (a
getaddrinfo failure on a literal IP is not a proxy-environment
symptom, and IPs need no DNS) — keeps the private-IP/metadata floor
intact under proxy env vars.
- Adds TestProxyEnvironmentDnsDelegation: delegation fires only for
hostnames, metadata hostname/IP floor holds, DNS-success path
unchanged, empty proxy var ignored.
- Guards the three pre-existing DNS-failure tests against ambient
proxy env vars so they don't flake on developer machines.

Follow-ups on the salvaged #54426 routing contract:
- Bare `model` without `provider` on the OpenAI-compatible endpoints
(/v1/chat/completions, /v1/responses) is now opt-in via
gateway.platforms.api_server.direct_model_requests (default off) —
generic OpenAI clients hardcode model names ('gpt-4o', ...) and
existing deployments rely on those falling back to the gateway
default. Explicit `provider` requests and the Hermes-native
session-chat + /v1/runs surfaces are always honored.
Idea credit: PR #22825 by @mssteuer.
- A model_routes alias with no `model` key can no longer leak the
alias string as the executing model name (defensive; parse-time
validation already drops such routes).
- Fix mis-indented _run_agent call args in _handle_session_chat_stream.
- Docs: document the opt-in flag.
Carry model, provider, and model_options through the API server's
execution surfaces (session chat, Chat Completions, Responses, /v1/runs)
without mutating global configuration. Precedence: session /model
override -> model_routes alias -> direct request selection -> global
defaults. Conflicting route/provider mixes fail closed with 400.
model_options stays request-scoped regardless of which selection wins.

test_docker_network_config.py landed on main after the #58489 revert and
stubbed docker ps with the 2-field ID\tState format. The re-landed
egress-aware reuse probe requests ID\tState\tEgressLabel when egress is
off, so the fake line failed to parse and the reuse path never fired.
Fixture-only change; production behavior is unchanged.
The gateway startup maintenance block gained a maybe_auto_archive call in
the same provably-off-loop __init__ site as maybe_auto_prune_and_vacuum;
bump the reviewed sync-escape count from 3 to 4.
New sessions.auto_archive / auto_archive_days config: soft-hide (never
delete) sessions with no activity for N days, aging on last activity
rather than creation so an old-but-active chat is spared. Sweeps are
throttled through state_meta and fire from CLI startup, gateway startup
+ hourly housekeeping, and the serve/dashboard backend (opportunistic
on session list + an hourly lifespan ticker), so every surface honours
one setting.
A new pinned column (declaratively migrated) exempts sessions from the
sweep; PATCH /api/sessions/{id} accepts pinned and flips the whole
compression lineage as a unit, mirroring set_session_archived.
