Change

Two places that read an acting agent's event stream by the CLI that wrote it did not know Pi's (#89):

• records.parse_log(log, backend, model) read every stream but Codex's as Claude Code's, so a Pi stream
  (pi --mode json) gave no session id and no usage. It now reads a pi stream with Pi's own reader (parse_pi).
  No hermit code calls it during a run (each CLI agent reads its own stream); hermit.agent.evolver.agent
  re-exports it for a method's code.
• The AHE Evolver's texts (START.md, DEBUGGER.md, the evolution query, the Debugger's question) name the acting
  agent's event stream. debugger.STREAM_TEXTS had only Claude Code's wording, so with a Pi acting agent they named
  agent-codex.jsonl, which is not there (rollout_stream finds agent-pi.jsonl). They now name Pi's stream and
  its command (pi --mode json).

Found while adding DeepSeek Harness (#90) and split out of it, so that #90 changes only dsh. #90 adds its own
entries beside these two (a one-line overlap in each place).

Validation

• tests/core/test_pi_agent.py::test_a_pi_stream_is_read_back_by_its_name_or_by_its_events: parse_log on the
  recorded tests/fixtures/pi/success.jsonl with pi gives the stream's session and its 4 calls (4,000 input and
  80 output tokens).
• tests/methods/ahe/test_ahe_hosts.py::test_the_evolvers_texts_name_every_acting_agents_stream_it_reads: for
  every stream but Codex's (Claude Code's, Pi's), START.md and DEBUGGER.md name that stream and no Codex file or
  command.
• Each test fails with its fix undone (each undone in turn in a copy of the checkout).
• Full suite, Linux container (Ubuntu 24.04) as root, --integration: 2 failed, 1165 passed, 85 skipped. On main
  the same run gives 2 failed, 1164 passed, 85 skipped: the same two tests, which fail as root
  (test_isolate::test_a_rollout_sees_what_is_declared_and_nothing_else,
  test_ahe_hook_runner::test_logs_that_cannot_be_written_lose_the_line_not_the_call).

Review

• Tests and documentation cover the affected behavior, where applicable. Tests: see Validation. Documentation:
  no document names parse_log or these texts.
• Commands, defaults, and public interfaces are consistent. parse_log keeps its signature; an unknown
  backend's stream is still read as Claude Code's.
• Shared logs and examples contain no credentials or private data. The fixture is Add Pi as a CLI Base Agent (acting agent and pi Evolver) #89's recorded stream.
• Documentation-only: N/A.
• Core changes: hermit/agent/base/records.py (parse_log) and the AHE method's debugger.py, both for a
  Pi acting agent.
• Real execution paths and tests: parse_log on a stream the real Pi recorded; the AHE texts as the
  learners read them.
• Test checklist: each test is in the group of its code, named for the behaviour, and fails without its fix.
• This description: TBD.
• Independent review (post-PR audit): pending.
