Compaction summaries now receive the current date and instruct the summarizer to rewrite completed actions as absolute, dated, past-tense facts (e.g. "email John about the proposal" -> "Sent the proposal email to John on 2026-06-07"). A resumed conversation no longer re-issues work that already happened or treats a finished action as still pending. The date is resolved via hermes_time.now() (date-only, user-configured timezone) inside _generate_summary. The compaction summary is a mid-conversation message that is never part of the cached prefix, so the date does not affect prompt-cache stability. Date resolution is best-effort: a clock failure omits the rule rather than blocking compaction. The rule rides the shared template, so both first-compaction and iterative-update prompts carry it. Inspired by Poke's summarization (temporal anchoring + semantic preservation).

Summary
Compaction summaries now produce absolute, dated, past-tense facts instead of leaving completed work phrased as open instructions — so a resumed conversation never re-issues a task that already happened.
The summarizer is handed the current date and told to rewrite e.g.
email John about the proposal→Sent the proposal email to John on 2026-06-07. Inspired by Poke's summarization layer (temporal anchoring + semantic preservation).Changes
agent/context_compressor.py—_generate_summary()resolves today's date viahermes_time.now()(date-only, user-configured timezone) and injects aTEMPORAL ANCHORINGdirective into the shared summary template. The rule rides the shared_template_sections, so both the first-compaction and iterative-update prompts carry it.tests/agent/test_context_compressor_temporal_anchoring.py— new tests.Why it's cache-safe
The compaction summary is a mid-conversation message that is never part of the cached prefix (compression is the one sanctioned mid-conversation mutation). The date here does not touch
system_prompt.pyand does not affect prompt-cache stability. This is deliberately distinct from the system-prompt timestamp, which stays byte-stable by design (PR #20451).Robustness
Date resolution is best-effort. If
hermes_time.now()raises, the rule is omitted and compaction proceeds normally — a clock failure can never block summarization.Validation
test_context_compressor_temporal_anchoring.py)py_compileTest coverage: first-compaction path carries dated rule, iterative-update path carries dated rule, clock-failure omits rule but still summarizes, date is sourced from
hermes_time.now().Infographic
