Slim salvage of #104688: place project context before workspace state and
keep cwd outside the stable prefix. Put runtime hints behind a final
renderer-owned boundary so quoted operator, memory, plugin and embedder
examples cannot override the persisted runtime cwd or identity fields.
Retain legacy unmarked prompt validation, add two invariant tests and a
credential-free real-AIAgent/git-worktree replay harness. No provider
cache-hit or billing measurements are claimed.

The usage anchor (real usage.prompt_tokens + delta estimate of what was appended since)
identified the priced transcript by id() of the last message, so it was None on EVERY
gateway turn (history is re-read from the DB each turn) and in every fresh process
(--resume, desktop per-turn serve). Those are exactly the surfaces where the bytes/4
estimate then fired local compression against payloads the provider priced far under
threshold (#99421, #104462).
- agent/usage_anchor.py owns the anchor: content fingerprint instead of id(), persisted on
the session row (model_config._usage_anchor) via set_usage_anchor(), restored on the first
resumed turn while the durable transcript still matches, cleared with the row on
compaction / codex-native rewrite / session reset.
- Callers repointed from model_metadata (the compat table follows).
Design and persistence slot from #99585 by @686f6c61; re-authored against the Sep 2026
layout (the branch predates the model_metadata / agent_init split).
Every PLUGIN-COMPAT __getattr__ now calls hermes_cli.plugin_compat.warn_once(facade, name, target) before
resolving, emitting a HermesPluginCompatWarning (FutureWarning) once per process per name: old path, new
path, removal target. Importing a facade for its live API stays silent; only resolving a moved name warns.
COMPAT_MANIFEST.md documents the warning and how to silence it during migration.
Verified the runtime never routes through a pointer: every entry point (run_agent, cli, hermes_cli.main,
gateway.run, tui_gateway.server, web_server, model_tools + tool discovery, hermes_state, cron.scheduler,
browser_tool, mcp_tool, kanban, auth) imports clean and `hermes doctor` runs end to end with the warning
promoted to an error.
Also restores the check_compat_pointers CI step to .github/workflows/lint.yml, which a0be177aac dropped
when the compat layer was regenerated (the lint script itself was present; the workflow step was not).
hermes_cli/plugin_compat.py, tests/test_plugin_compat_warning.py and the two-line insert per facade are
part of the compat layer and go away with it.
The Sep 2026 decomposition (PR #102117) makes internal import paths a non-API: names now live in
the focused modules that define them. This commit is the ONLY thing keeping the old paths alive,
so external plugins have time to update. It is deliberately a single, unsquashed commit:
git revert <this sha>
removes every shim, stub and manifest at once on the announced date. Nothing in-tree may depend on
these pointers: scripts/check_compat_pointers.py (wired into lint.yml) fails CI if it does.
What it adds (see COMPAT_MANIFEST.md, compat_manifest.json):
- 332 facade modules get one delimited `PLUGIN-COMPAT` block appended at the end of the file
- 1,172 moved names resolved lazily via a module `__getattr__` (PEP 562) — never a top-level import,
so no import cycles; facades that already had `__getattr__` get a chained one
- 592 third-party/stdlib names the old modules used to expose, with their original import statements
- 266 public definitions that had been deleted as unused, restored byte-for-byte from the pre-decomposition
tree (+40 private helpers and 16 imports pulled in only because a restored definition needs them)
- 3 deleted modules recreated as re-export stubs (gateway/startup_watchdog, hermes_cli/observability/
relay_runtime, tools/environments/modal_utils)
- private names (`_x`) get no pointer: they were never API (3,792 skipped)
Verified: all 335 touched modules import under a fresh HERMES_HOME and every manifest name resolves;
the lint reports zero in-tree uses; ruff clean; targeted suites unchanged.
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
Message-only rearm could sit just above the body estimate while provider
prompt_tokens (system + tool schemas) already exceeded threshold_tokens,
so prune no-oped forever with no log. Bypass that rearm short-circuit on
the billed basis, warn once when over-threshold reclamation no-ops, and
name attempts_exhausted when should_compress_info says run but the loop
skips.
Fixes#101889
Call the existing keep-newest vision retirement on the per-call
api_messages clone after sanitization so OpenAI-style tool-result
screenshots are not re-uploaded on every later turn.
Follow-ups from review of the two salvaged #87490 commits:
- _pressure_with_real_floor now applies only on the rough fallback branch.
A valid usage anchor is provider-exact and wins as-is: on MoA turns the
anchor deliberately uses the pre-fold aggregator usage while
last_real_prompt_tokens holds the folded figure, so flooring the anchored
value would re-add fan-out tokens the anchor exists to exclude. Docstring
rewritten to describe the real path split (anchor since d3a1c46510).
- estimate_tokens_rough: encode with errors="replace". main's estimator
never raised; text.encode() on a lone surrogate (routine in tool output,
see message_sanitization) raised UnicodeEncodeError and would abort a
turn where main produced a slightly-off number.
- Record the cl100k/o200k/Qwen2.5 calibration for the bytes/4 rule.
- tests: accented Latin within +10% of the ASCII rule; mixed Cyrillic/ASCII
counts ASCII at one byte; lone surrogates don't raise; anchored pressure
is never floored (wiring shape).
The chars/4 rough estimate under-counts Cyrillic and other non-ASCII scripts
by up to ~2x, so a session can ride the provider's real context ceiling while
the rough pressure stays under the compaction threshold. On providers that
silently clip over-window prompts (ollama /v1) the reactive overflow handler
never fires either, and the length-continuation retry path re-enters the API
call without passing the post-response gate — reproducing the truncation
death spiral this branch already addresses (observed live after the first
commit: real prompts 64,842 -> 64,995 against a 55,705 threshold, output
room shrinking 694 -> 541 tokens).
Floor the pre-API pressure figure at the provider's last reported
prompt_tokens — authoritative, script-independent — except for the one turn
after a compaction when that value is known-stale (#36718's
awaiting_real_usage_after_compression window).
The 'Nous agent key refreshed after 401' message used a bare print(),
making it always visible. The equivalent xAI/Codex, Copilot, and Anthropic
auth-refresh messages all use _buffer_vprint() (verbose-gated). This brings
the Nous path in line with the others so the routine ~15min OAuth key
refresh no longer prints noise on every retry.
Policy: availability-gated tools (check_fn probes — Docker, HASS_TOKEN,
OAuth…) are frozen for the life of a session. tools[] only changes on
/new, /reload-mcp, or compaction. Two doors remained after #100638:
* Gateway agent-cache eviction (LRU/idle sweep/cross-process invalidation)
rebuilds a fresh AIAgent for the SAME session and agent_init re-derives
agent.tools from live probes with no predecessor to preserve. Persist
the session's resolved tool-name order in a new `sessions.tool_names`
JSON column (declarative reconciliation, SCHEMA_VERSION 28), written
alongside the system prompt and re-pinned on every published refresh
(so /reload-mcp and compaction naturally reset it; /new mints a new
row). On restore-for-existing-session the fresh definitions are folded
onto the saved order via the SAME `_merge_preserving_prefix` helper —
a probe-flipped tool is carried forward from the registry schema, a
deregistered one dropped, new tools appended at the tail.
* /reload-mcp (CLI, gateway, TUI RPC) now also calls
`reprobe_tool_availability()` — drops the check_fn verdict cache and the
get_tool_definitions memo — so a user can consciously pick up a
credential/daemon that appeared mid-session. Docs updated.
