marfrit 31e5de5ad5 docs/PHASE9: analyze + baseline + plan (single bundled commit)
Bundled the three doc steps since the surface is small (4-commit
impl, no major redesigns from formulate).

Analyze findings (12, A1-A12):
  A1-A2 — main.lua surface clean; no new FFI needed
  A3   — Q-P2 RESOLVED via baseline: sha256sum (GNU coreutils)
  A4   — Q-P1: trust prompt AFTER user-config status line
  A5   — Q-P3: don't log walk-up by default; :config show on demand
  A6   — Q-P5: :cfg show top-level by default; `full` for deep
  A7   — Q-P6: project may set secrets.vault (covered by trust prompt)
  A8   — Q-P4 DEFERRED: rl.readline early-startup smoke at impl time
  A9   — walk-up perf <1ms even pessimistic
  A10  — trust-file race: JSONL append-only handles concurrent writes
  A11  — sandboxed dofile out of scope (trust prompt IS the gate)
  A12  — bootstrap order is correct: user→project→secrets_session

Baseline:
  B1 — sha256sum + openssl agree byte-for-byte on noether;
       sha256sum chosen (universal + simpler parse).

§10 Open Qs table now shows resolutions inline (5/6 done; Q-P4
deferred to implement-time smoke).

§13 Implementation Plan added — 4 commits:
  1. history.lua: trust file helpers (read/add/is_trusted + _sha256_file)
  2. main.lua: walk-up + load_config_with_overlay + trust prompt
  3. repl.lua: :config show meta + startup status line
  4. config.lua header note + status -> Implement

Per-commit risk index covers sha256sum-missing case, JSONL partial
write, A8 rl.readline early-startup, symlink-loop walk-up,
:config show token leakage via conservative masking heuristic.

Open at plan-time (resolve at impl):
  - A8 rl.readline behavior; fall back to io.read if broken
  - $AISH_TRUST_FILE env override for CI isolation

marfrit 4f5c3aeba9 docs/PHASE9: formulate — project-local config overlay (.aish.lua)
Phase 9 formulate manifest + PHASE0 §11 amendment (adds Phase 9 row)
+ PHASE0 §10 amendment (config resolution order now references Phase
9's overlay step). Substrate-touch lands same commit per CLAUDE.md §3.

Four pillars:

  1. .aish.lua walk-up from cwd; stops at $HOME or filesystem root.
     First found file becomes the project layer. Absence = no-op.

  2. Shallow merge over user config: project top-level keys REPLACE
     user keys. Predictable; deep merge surprises with array/table
     semantics. Users compose full blocks explicitly.

  3. Trust prompt + sha256-pinned persistence in ~/.aish/trusted-
     projects (JSONL, mode 0600). First encounter prompts; subsequent
     startups load only if recorded sha matches. Content change ->
     re-prompt. Matches direnv-allow security posture.

  4. :config show meta — lists each source path with the top-level
     keys it contributed + sanitized effective config dump
     (token-bearing fields masked).

Key design decisions documented:

  - Trust mechanism is explicit (not default-trust-all-cwds) —
    .aish.lua runs arbitrary Lua via dofile; hostile cloned-repo
    case is a real concern.
  - $HOME boundary on walk-up — don't search /tmp or /. Repos
    outside $HOME get no project layer.
  - Reload on cd: NO. Config resolved at startup only.
  - sha256 via shelled `sha256sum` (POSIX-portable; avoid
    vendoring a Lua impl).

§9 risk table covers: hostile repo (trust prompt), corrupted trust
file (best-effort skip), updated repo (sha mismatch re-prompts),
dofile errors (pcall-protected), walk-up safety ($HOME boundary).

6 open questions for analyze:
  Q-P1 — trust prompt before/after startup status
  Q-P2 — sha256sum vs openssl dgst (baseline)
  Q-P3 — log walk-up path?
  Q-P4 — rl.readline safe at startup?
  Q-P5 — :config show full vs top-level
  Q-P6 — project-set secrets.vault security

Scope confirmed via AskUserQuestion: project-local overlay (chosen
over cost preflight enforcement and cross-session cost persistence,
both deferred as Phase 10 candidates per §11).

marfrit 08dba69fce config + docs/PHASE8: example block + status -> Implement (Phase 8 commit #5)
config.lua:
  - Commented-out `tokenize = { use_endpoint = true }` block with
    parity to the Phase 1-7 example blocks.
  - Documents the two consequences: (1) per-turn network cost
    (~30ms first time, cached after) and (2) token_budget is now
    actually enforced — sessions that fit under char/4 may evict
    earlier under accurate counts.
  - Notes cloud /tokenize 404 fallback path.

docs/PHASE8.md:
  - Status header bumped: "Plan + review fold-in" -> "Implement"
  - Lists the 5 implement commits inline for traceability:
      7ef2a6e  broker: token_count + endpoint cache
      8502517  context: tokenize_fn + _tokens cache
      db26d0c  context: enforce_budget honors token_budget (R2 guard)
      94b7d86  repl: wire tokenize_fn + :cost detail estimate row
      this     config example + status bump

Phase 8 implementation is complete. Resolves Q1 (PHASE0 §13,
originally Phase 3, deferred forward). Next inner-loop step: verify
(7) — file test cases, run autonomous, close. Then memory-update (8).

marfrit 94b7d86926 repl: wire tokenize_fn + :cost detail estimate row (Phase 8 commit #4)
Activates Phase 8 pillars 2+3+5 end-to-end and adds the R3-revised
:cost detail trailing line.

Changes:

- When cfg.tokenize.use_endpoint is true, ctx_opts.tokenize_fn is
  set to `function(text) return broker.token_count(active_cfg, text) end`
  before Context.new fires. R4: the closure body references
  active_cfg DIRECTLY (upvalue) — Lua resolves upvalues at call
  time, so subsequent :model switches re-route to the new model's
  tokenizer automatically (verified by E2E: :model cloud after the
  fast call still produces clean estimate row).

- :cost detail gains a trailing line per R3:
    estimated session ctx: <N> tokens; token_budget=<M> (X.Y% used)
  N comes from ctx:estimate_tokens() (current in-memory snapshot,
  NOT a comparison against the accumulator sum above which is
  cumulative across calls + evicted turns). Gives at-a-glance
  budget utilization.

E2E verified against live broker:
  - fast model call -> 168 tokens estimated (real BPE via /tokenize)
  - :model cloud + cloud call -> 178 tokens estimated (closure
    follows :model switch correctly per R4)
  - 21% / 22.3% budget utilization shown
  - Accumulator sums and estimate are intentionally different
    (sums are cumulative, estimate is current snapshot) — R3-
    correctly displayed as separate lines

With this commit landed, Phase 8 is functionally complete; commit
#5 is config example + status bump.

marfrit db26d0ccb7 context: enforce_budget honors token_budget + R2 guard (Phase 8 commit #3)
Pillar 5 (analyze finding A1) — the real value-add of Phase 8.
Until now, ctx.token_budget = 4096 was set but never enforced;
enforce_budget only looked at max_turns. With commit #2's accurate
tokenization wired in (via commit #4), eviction now finally fires
when the actual context fills the budget.

Loop condition change:

  before:
    while #self.turns > self.max_turns do

  after:
    while (#self.turns > self.max_turns
           or self:estimate_tokens() > self.token_budget)
          and #self.turns > 0 do

R2 guard: the `and #self.turns > 0` clause is essential. When
system_prompt alone exceeds token_budget (e.g. a 5000-token [project]
block with token_budget=4096), the OR-condition stays true even
when turns are empty — table.remove on a 0-length list would
no-op forever while evicted++ spins. Sonnet review caught this;
without the guard, real users could hit an infinite loop just
by setting a small token_budget + opening a large project tree.

Per-pair eviction logic (summarize callback + pair-pop) inside the
loop is unchanged. The estimate_tokens call is potentially expensive
under tokenize_fn — commit #2's per-turn cache amortizes to O(N)
per iteration after first fill; for max_turns=40 + budget=4096
sessions the worst case is microseconds per call.

Unit-verified across 5 cases (with and without tokenize_fn):
  1. max_turns eviction unchanged (no behavior regression).
  2. char/4 path: tight budget evicts to 0 when sys > budget,
     exits via R2 guard.
  3. char/4 path: practical budget evicts to a stable count.
  4. tokenize_fn stub: evicts to exactly the (budget - sys)/per-turn
     count.
  5. R2 critical: zero turns + oversize sys -> immediate exit,
     evicted=0, no spin.

Behavior change for existing users: a session that fit under
token_budget=4096 by char/4 (~16K chars) may now evict earlier
because accurate counts are HIGHER for most natural-text inputs
(per baseline B2). Users on cloud presets with very large context
windows (Claude 200K) should raise token_budget to match — see §9
risk row in PHASE8.md.

marfrit 8502517021 context: tokenize_fn + per-turn _tokens cache (Phase 8 commit #2)
Foundation for accurate Context:estimate_tokens. When the optional
tokenize_fn is wired (Phase 8 commit #4 wires it from repl.lua),
estimate_tokens uses it with per-turn caching for O(1) amortized
cost. char/4 path unchanged when tokenize_fn nil.

Changes:

- Context.new accepts opts.tokenize_fn -> stored as self.tokenize_fn.

- Context:estimate_tokens:
    if tokenize_fn nil -> existing char/4 (no behavior change).
    if tokenize_fn set ->
      - tokenize self.system_prompt every call (dynamic per
        compose_background/project/summary; can't cache).
      - for each turn: if t._tokens nil -> compute + cache; else
        use cached. Turn content immutable after append (we never
        mutate stored turns) so cache never goes stale.

- :reset wipes self.turns which takes the _tokens cache with them;
  new turns start with t._tokens == nil and lazy-set on first count.

8/8 unit cases verified:
  - char/4 path unchanged when no tokenize_fn
  - tokenize_fn called 1+ N times on first estimate (sys + N turns)
  - subsequent estimates fire only 1 tokenize call (sys; turns cached)
  - new turn fires +1 tokenize call on next estimate
  - :reset + fresh turn fires fresh tokenize call (cache died with turn)

No callers wire tokenize_fn yet — Phase 8 commit #4 lands the
repl.lua wiring (after commit #3 adds the enforce_budget extension
that's the real beneficiary of accuracy).

Regression: test_safety 87/87, test_router_model 31/31.

marfrit 7ef2a6ed5c broker: token_count + endpoint capability cache (Phase 8 commit #1)
Foundation for Phase 8 — accurate tokenization via <endpoint>/tokenize
where supported, char/4 fallback otherwise.

Changes:

- `M.token_count(model_cfg, text)`:
    Empty text -> 0.
    No endpoint -> char/4 immediately.
    Capability cache says false -> char/4.
    Otherwise -> POST `<endpoint>/tokenize` with `{content, model}`,
    2s timeout. On 200 + parseable `{tokens=[...]}`: cache true,
    return #tokens. Anything else (non-200 / parse-fail / transport
    err / timeout): cache false, char/4.

- `_tokenize_capable` cache keyed by ENDPOINT ONLY per R6 — B1
  confirmed /tokenize ignores the model field, so same-endpoint
  presets share one cache entry. If a future broker honors the
  model field, revisit.

- `M.tokenize_supported(model_cfg)`: returns nil/true/false for
  the cached state (introspection for tests + future :tokenize meta).

- `M._reset_tokenize_cache()`: test hook so the session-local cache
  doesn't leak between test runs sharing a LuaJIT VM.

Live verified against hossenfelder + a deliberately-broken endpoint:
  - "hello world" -> 2 tokens (matches manual curl probe)
  - 901-char text -> 201 real tokens vs 225 char/4 (24-token gap;
    real is LOWER here, opposite direction from the README probe
    where it was higher — confirms heuristic is inaccurate in both
    directions)
  - Pre-probe: tokenize_supported() returns nil
  - Post-probe: tokenize_supported() returns true (local) / false (broken)
  - Broken endpoint second call: still char/4, no re-probe
  - Empty / nil text edge cases handled

marfrit 467e573d24 docs/PHASE8: review fold-in — 2 BLOCKERs + 4 CONCERNs + 4 NITs
Sonnet-reviewed per reviews-use-sonnet memory directive.

BLOCKERs (RESOLVED in-place):

R1. §5 estimate_tokens pseudocode missing per-turn cache pattern.
    Prose described it; code block called tokenize_fn unconditionally.
    Implementer following code verbatim would hit the O(N round-
    trips per call) perf gap the prose flagged. Code block now
    shows explicit `if t._tokens then ... else t._tokens = ... end`.

R2. enforce_budget loop can spin forever when system_prompt alone
    exceeds token_budget (e.g. 5KB project block + budget=4096 +
    zero turns -> turns can't shrink further but OR-condition stays
    true). Fix: AND `#self.turns > 0` guard on the loop. §13 commit
    3 row shows the explicit Lua-syntax condition.

CONCERNs (FOLDED):

R3. :cost detail per-slot ~est=N annotation was semantically
    undefined — accumulator sum (cumulative across calls + evicted
    turns) vs current-snapshot estimate are incommensurable. §6
    reworked: ONE trailing summary line "[estimated session ctx:
    N tokens; token_budget=M (X% used)]" instead of per-slot
    annotations. §13 commit 4 aligned.

R4. tokenize_fn closure MUST reference active_cfg as upvalue (NOT
    capture by value). Subtle but easy to miss — §13 commit 4 now
    spells out the correct vs wrong patterns explicitly.

R5. 2s tokenize timeout can spuriously cache-as-unsupported when
    llama.cpp is busy with a concurrent completion (single-threaded
    inference; /tokenize queues behind). Documented in §9; v1
    ships 2s, revisit during verify if it bites.

R6. Per-endpoint cache key conflated two same-endpoint/different-
    model presets (B1: /tokenize ignores the model field). Cache
    key simplified to endpoint-only. One probe per endpoint per
    session; if a future broker honors the model field, revisit.

NITs (APPLIED):

N1. §13 commit 3 `OR`/`AND` -> Lua-syntax `or`/`and`.
N2. §10 Q-T5 Resolution-target cell filled in (was blank after B1).
N3. §6 / §8 / §13 commit 4 now describe a CONSISTENT approach
    (trailing summary line; per-slot annotation dropped).
N4. Status header tree-hash updated to current (aa64ad3 -> stays
    fresh through review fold-in; commit 5 will refresh again
    at "Implement" status).

PHASE8.md now 622 lines (was 454 after plan). +168/-61. Ready for
implementation phase 6 of the inner loop.

marfrit aa64ad3eec docs/PHASE8: plan — §13 commit roadmap (5 commits)
Status: Analyze -> Plan. All open Qs resolved (Q-T5 via baseline B1).

5-commit roadmap, bottom-up:

  1. broker.lua — M.token_count helper + per-endpoint capability
     cache. <endpoint>/tokenize probe with 2s timeout; cache true/false
     per (endpoint, model) for the session. char/4 fallback on any
     non-200 / parse-fail / transport err. M.tokenize_supported
     introspection helper.

  2. context.lua — Context.new accepts opts.tokenize_fn; estimate_
     tokens widens to use it when set, with per-turn `_tokens` cache.
     char/4 path unchanged when tokenize_fn nil.

  3. context.lua — enforce_budget consults token_budget too (pillar
     5 from A1). Loop condition: turns>max_turns OR estimate_tokens
     >token_budget. Existing summarize-on-evict callback unchanged.

  4. repl.lua — wire tokenize_fn when cfg.tokenize.use_endpoint=true.
     Closure captures active_cfg upval (A5 — follows :model switches
     naturally). :cost detail extension: trailing line showing
     estimated session ctx tokens for comparison with the per-slot
     prompt_tokens sums in the accumulator.

  5. config.lua commented `tokenize = { use_endpoint = true }`
     example + PHASE8.md status -> Implement.

Per-commit risk index covers: probe latency cap (2s, one-shot),
per-turn cache correctness (immutable post-append), enforce_budget
performance (O(N) per call after cache fill), and the intentional
behavior change of token_budget actually being enforced (sessions
fitting under char/4 may evict earlier under accurate counts —
documented in §9).

Two items open at plan, resolve at implement:
  - exact :cost detail layout for estimated session ctx row
  - whether to add a :tokenize debug meta (defer unless useful in verify)

marfrit 79bd40db79 docs/PHASE8-baseline: live /tokenize probes
Four findings, all align with formulate/analyze:

B1. /tokenize IGNORES the `model` request field — returns the
    tokenization of whichever model is currently loaded on the
    proxy backend, NOT the requested model. Acceptable: a real BPE
    count is still much better than char/4, and the gap between
    Qwen/Llama tokenizers is small. Cloud (OpenRouter) 404s
    regardless, so cloud falls back to char/4 via the capability
    cache.

B2. Latency 23-34ms per call, FLAT across input sizes 50-5000 chars.
    Network round-trip dominates. Per-turn _tokens cache amortizes
    to O(1); worst case 40 cached turns × ~30ms = 1.2s one-time
    cost on first enforce_budget call. Acceptable.

B3. Response shape confirmed: `{"tokens":[N1,N2,...]}` (token IDs;
    we use #response.tokens for count, discard the IDs). JSON not
    SSE; ffi.curl.M.post is the right call.

B4. Cloud /tokenize 404s as expected. Capability cache marks it
    unsupported on first probe; char/4 fallback silent thereafter.
    No design change.

Q-T5 RESOLVED per B1. All open questions now resolved.

marfrit 1a136d81b7 docs/PHASE8: analyze — adds pillar 5 (enforce_budget honors token_budget)
Status: Formulate -> Analyze. 12 findings (A1-A12); 5/6 open Qs
resolved in-place (Q-T5 deferred to baseline).

MAJOR FINDING:

A1. enforce_budget ONLY checks max_turns, NOT token_budget — even
    with accurate tokenization, eviction decisions are unaffected.
    The new estimate_tokens() would just feed the prompt template
    display. Pillar 5 added: enforce_budget evicts when EITHER
    max_turns OR token_budget is exceeded. This is the real
    motivation for accurate tokenization.

Other findings:

A2.  ffi.curl.M.post signature confirmed (body, status) / (nil, err).
A3.  Single caller of estimate_tokens today; enforce_budget becomes
     the second (more frequent) caller — per-turn _tokens cache
     becomes important.
A4.  Q-T1: cache lives on turn dict; dies with turns on :reset.
A5.  Q-T2: closure captures active_cfg upval; follows :model switch
     naturally.
A6.  Q-T3: opt-out skips the probe entirely (no wiring).
A7.  Q-T6: tools-schema tokens deferred to follow-up (fixed per
     session; under-count bounded).
A8.  _tokens cache invalidation: only :reset; turn content is
     immutable after append.
A9.  Probe latency ~50ms/call locally; per-turn cache amortizes to
     O(1) after first count.
A10. estimate_tokens called OUTSIDE streaming callback; no race.
A11. role:"tool" turns tokenize identically; per-turn cache works.
A12. include_usage (Phase 7) and tokenize (Phase 8) are orthogonal —
     different endpoints, different code paths.

§1 expanded to 5 pillars (pillar 5 = enforce_budget extension).
§3 context.lua row updated to reference the enforce_budget change
+ per-turn _tokens cache. §9 risk row added: accurate counts mean
the default token_budget=4096 is finally ENFORCED — sessions that
spilled silently under char/4 may now evict earlier.

marfrit 00869ba412 docs/PHASE8: formulate — accurate tokenization (resolves Q1)
Phase 8 formulate manifest + PHASE0 §11 amendment to add the Phase 8
row (substrate amendment per CLAUDE.md §3 lands same commit).

Four pillars:

  1. Per-endpoint /tokenize probe (cached). One round-trip on first
     call per (endpoint, model); capability cached for session.
     hossenfelder + llama.cpp expose <endpoint>/tokenize (NOT /v1/
     tokenize — per real probe; the path is endpoint-local, not
     under the OpenAI /v1 prefix). Cloud (OpenRouter) 404s — silent
     char/4 fallback.

  2. broker.token_count(model_cfg, text) — thin wrapper; tries probe,
     falls back to char/4 on miss. Always returns non-negative int;
     never errors. 2s tight timeout; failures cache as not-supported.

  3. Context:estimate_tokens widened. Accepts optional tokenize_fn at
     Context.new; uses it when present, char/4 otherwise. repl.lua
     wires `tokenize_fn = function(text) return broker.token_count(
     active_cfg, text) end` when cfg.tokenize.use_endpoint = true.
     Per-turn _tokens cache to amortize across estimate calls.

  4. :cost detail est-vs-actual annotation. When the heuristic
     disagrees with the actual prompt_tokens from broker usage by
     >10%, show `~est=N`. Silent otherwise. Display-only; no
     behavior change.

Resolves Q1 (PHASE0 §13, originally Phase 3) — replace char/4
heuristic on Context:estimate_tokens. Originally targeted at Phase 3
but deferred forward each iteration; now lands.

Baseline already observed during formulate:
  - /v1/tokenize -> 404 on hossenfelder; /tokenize -> works
  - Body shape: {content: "..."} returns {tokens: [N1, N2, ...]}
  - Accuracy gap: char/4 UNDERESTIMATES by ~10% on real code/prose
    (508 vs 558 on a 2KB README sample). Material for context-
    budget eviction decisions.

Doc covers scope + done-when, tech decisions table, module changes,
per-pillar deep dives, UX surface, out of scope, 6 risk rows, 6
open questions (Q-T4/T5 baseline-bound, others analyze-bound).

Scope confirmed via AskUserQuestion: tokenization (chosen over
cross-session cost persistence and hard rate-limit enforcement).

marfrit 0d6ff93134 repl: :cost meta surface (Phase 7 commit #5)
User-facing reporter of the per-session accumulator. Three shapes:

  :cost            one-line summary (calls / tokens / cost)
  :cost detail     per-model + per-category breakdown
  :cost reset      zero the meter; clears warn flags

All read-only against ctx.usage_totals; no broker calls.

R6 — annotation uses the per-slot is_local sticky flag, NOT a fragile
cost==0 heuristic. Summary line classifies:

  cloud only -> "cost=$X.XXXXXX"
  cloud + local mix -> "cost=$X.XXXXXX (cloud only; local: tokens
                       but no cost field)"
  local only -> "cost=$X.XXXXXX (local only; no cost field)"

R7 — :cost detail rows sort by (cost desc, model asc, category asc).
Three-level key for deterministic output across equal-cost rows
(table.sort is unstable; identical costs would otherwise reorder).

R10 — all dollar values use $%.6f formatting. Sub-cent precision is
critical: a Haiku call can cost $0.000028; $%.4f would round it to
$0.0000 — indistinguishable from local $0.

Column width widened to %-26s to fit fully-qualified cloud model
names (e.g. "anthropic/claude-haiku-4.5" = 25 chars).

E2E verified against live cloud + local broker:

  :cost (empty session)          -> "0 calls, $0.000000"
  ...after mixed-mode session...
  :cost                          -> "5 calls, prompt=472 / completion=26
                                     tokens, cost=$0.000377 (cloud only;
                                     local: tokens but no cost field)"
  :cost detail                   -> 4 rows: main cloud $0.000219, probe
                                     cloud $0.000128, delegate cloud
                                     $0.000030, main local $0.000000
                                     (local). Sort by cost desc within
                                     model.
  :cost reset                    -> "cost meter reset"; subsequent
                                     :cost shows zeros.

All 5 categories appeared in the same session: main (twice — cloud
+ local), delegate, probe (x2 from :safety check). Warn-threshold
firing already verified in commit #3 + #4.

HELP gains 3 :cost lines.

marfrit b30212af0f safety + repl: opts.category for Norris + probe (Phase 7 commit #4)
Closes the last two broker call sites that flow through safety.lua.
Together with commits #1-#3, all 7 broker call sites in aish now
attribute usage to the cost accumulator under the right category.

Changes:

  safety.lua:

  - llm_probe (the YES/NO destructive checker) — broker.chat call
    gains opts.category = "probe". Captures (text, usage) via
    (reply, second) and, when opts.on_usage is provided AND the
    call succeeded, routes second through opts.on_usage(model,
    category, payload). N4 signature chain: opts already flowed
    through llm_second_opinion -> M.is_destructive from #52's
    work; opts.on_usage rides along naturally with no further
    signature change.

  - M.norris_step (Norris main broker round-trip):
      * opts to broker.chat_stream gains category = "norris"
      * probe_opts (passed to is_destructive inside the loop)
        gains on_usage = helpers.on_usage so the LLM probe's
        cost lands under "probe" too
      * on_delta wrapper adds elseif kind == "usage" branch that
        calls helpers.on_usage(payload.model, payload.category,
        payload). Coexists cleanly with the existing text (rehydrator)
        and tool_call branches.

  repl.lua:

  - Norris helpers table gains on_usage = _record_usage. The R5
    central chokepoint (commit #3) does the warn-threshold check
    AND ctx:add_usage atomically.

  - :safety check meta's probe_opts always carries on_usage now
    (independently of whether secrets_session is set). secrets-aware
    scrub_msgs/rehydrate added conditionally as before.

E2E verified against live broker (safety.llm_model = "cloud"):
  - :safety check ls -la /tmp -> 2 cloud probe calls
  - "[aish] session cost $0.000128 has crossed warn_at_dollars=$0.000100"
  - probe category visible in accumulator (would appear in :cost detail
    once commit #5 ships the meta).

marfrit 8adebd52cc repl: _record_usage helper + opts.category at 5 sites (Phase 7 commit #3)
Wires broker.lua's on_delta("usage", payload) and broker.chat's
(text, usage) return to the ctx accumulator via a single chokepoint.

Changes:

  - Forward decl `local _record_usage` near _bg_spawn — same pattern;
    the summarize-on-evict closure in make_summarize_fn (built at
    line 299) needs lexical access to _record_usage (assigned at
    line 695), so forward-declare and assign-without-`local`.

  - _record_usage(model, category, usage) — R5 central chokepoint:
    routes to ctx:add_usage, then checks the per-threshold warn
    state. R4: cost_warn_state has two independent flags (dollars
    and tokens) so first-to-fire doesn't suppress the other. R10:
    warn message uses $%.6f for sub-cent precision.

  - call_broker wrapper: wrapped on_delta now branches on
    kind == "usage" -> _record_usage(payload.model, payload.category,
    payload). R2: keys by payload.model (set inside broker.lua from
    model_cfg.model). When fallback fires, broker is called with
    fb_cfg, so payload.model IS the fallback's name automatically —
    wrapper doesn't track primary-vs-fallback itself.

  - 5 caller sites wired with opts.category:
      ask_ai call_broker             -> category="main"
      summarize-on-evict             -> category="summarize"
      DELEGATE: handler              -> category="delegate"
      :memory summarize              -> category="memory_summarize"
      :delegate meta                 -> category="delegate"

  - All 4 broker.chat call sites switched from
      local reply, err = broker.chat(...)
    to
      local reply, second = broker.chat(...)
    branching on reply nil-ness to interpret second (err on failure,
    usage on success). Captured usage routes through _record_usage.

E2E verified against live cloud broker:
  - cloud prompt -> reply "Hi! 👋"
  - Warn fired: "session cost $0.000219 has crossed warn_at_dollars=$0.000010"
  - R10 sub-cent precision visible in both numbers.

Norris + safety paths still untouched — commit #4 wires those.

marfrit 7b4a9becc2 context: cost/usage accumulator (Phase 7 commit #2)
Adds the per-conversation accumulator that broker.lua's
on_delta("usage", ...) payload feeds into. No callers yet —
commit #3 wires the broker callback to ctx:add_usage in repl.lua,
commit #4 in safety.lua.

Changes:

- Context.new: new fields `usage_totals = {}` and
  `cost_warn_state = { dollars = false, tokens = false }`. R4:
  two independent flags so warn_at_dollars firing doesn't
  suppress warn_at_tokens (or vice versa).

- Context:add_usage(model_name, category, usage):
  Increments usage_totals[model_name][category] slot. R6: when
  usage.cost is nil (local llama.cpp per B3), sets a sticky
  `is_local = true` flag on the slot AND does NOT add to cost
  (preserves the local-vs-cloud-zero distinction for :cost detail
  annotation). When usage.cost is a number (cloud), accumulates.

- Context:total_cost() / total_tokens() — pure-Lua summation
  across all slots; total_tokens returns (prompt, completion).

- Context:reset_usage() — explicit :cost reset path; zeros
  usage_totals AND clears both flags atomically.

- Context:reset() — R8 parity: does NOT clear usage_totals OR
  cost_warn_state. Matches the Phase 4 memory_items / Phase 6
  project rule ("ambient context survives a user-driven
  conversation reset").

Smoke verified (20/20 unit cases):
  - Empty zeros; cloud cost accumulation; local nil-cost preserves
    is_local=true sticky; calls counter; cost summation across
    multiple cloud calls; is_local sticky after a later nil-cost
    call on a cloud slot; separate slots per (model, category);
    :reset preserves; :reset_usage zeros both totals and flags.

marfrit 7364963b00 broker: usage capture + opts widening (Phase 7 commit #1)
Foundation for Phase 7. broker.chat_stream now emits a third
on_delta kind ("usage") after the stream completes successfully;
broker.chat returns (text, usage). Backward-compatible — existing
callers that ignore the new kind / second value continue working
via Lua's drop-extra-returns semantics.

Changes:

- build_request widens (A3 + R3) — `(model_cfg, msgs, stream, opts)`.
  opts.tools / opts.max_tokens / opts.include_usage / opts.category
  all live inside opts now. Both internal call sites updated.

- opts.include_usage defaults to true for streaming requests; sets
  `stream_options: { include_usage: true }` in the request body.
  B1: required for local llama.cpp to emit usage; cloud honors as
  a no-op (emits anyway).

- on_event captures `doc.usage` into a closure-local `final_usage`.
  N1: the check is INDEPENDENT of the choice/delta branches — local
  emits usage on choices=[] chunks (choice nil) while cloud emits
  with non-empty choices + finish_reason. Both shapes funnel here.

- After curl.post_sse returns successfully (NOT on transport/api
  errors), if final_usage is set, emit on_delta("usage", {prompt_tokens,
  completion_tokens, total_tokens, cost, model, category}). cost is
  nil for local (R6 preserves the nil vs 0 distinction the
  accumulator needs). model is model_cfg.model — caller-stable per
  B4 + R2 so call_broker's fallback retry attributes usage to the
  fallback's model name without wrapper-side tracking.

- M.chat (R1 — BLOCKER fix): on_delta now also captures kind=="usage"
  alongside "text"; M.chat returns (text, usage). Without this fix
  4 of 5 non-streaming categories (summarize / delegate /
  memory_summarize / probe) would silently report zero usage.

Smoke verified against live hossenfelder:8082:
  - CLOUD chat   -> (text, usage); cost=2.9e-05, model=anthropic/...
  - LOCAL chat   -> (text, usage); cost=NIL (correct per R6),
                    model=qwen-coder-7b-snappy-8k
  - CLOUD stream -> on_delta("usage", {...}) with category="test"
                    echoed; model name caller-stable.

marfrit d4c20f09df docs/PHASE7: review fold-in — 3 BLOCKERs + 6 CONCERNs + 5 NITs
Sonnet-reviewed (per the reviews-use-sonnet feedback memory).

BLOCKERs (RESOLVED in-place):

R1. M.chat would silently return (text, nil) for ALL non-streaming
    callers — 4 of 5 categories (summarize/delegate/memory_summarize/
    probe) flow through broker.chat, NOT chat_stream. §4 now shows
    the explicit M.chat update that captures kind=="usage" alongside
    "text" and returns (text, usage).

R2. call_broker fallback retry would credit usage to the wrong model
    name. Fix: broker emits payload.model = model_cfg.model (which IS
    the fallback's name when called with fb_cfg — chat_stream's
    upvar). Wrapper keys by payload.model, NOT outer model_name. §4
    + §13 commit 3 reflect.

R3. build_request has TWO internal callers inside broker.lua itself,
    not just the public surface. Plan §13 commit 1 risk row now
    spells this out explicitly so the implementer doesn't read "every
    caller already passes opts" as "external-only".

CONCERNs (FOLDED):

R4. Single cost_warn_fired flag covers two thresholds — first-to-fire
    suppresses the other. Split into ctx.cost_warn_state = { dollars
    = false, tokens = false }; :cost reset clears both. §7 + §13.

R5. Warn-check centralization — single _record_usage helper in
    repl.lua wraps ctx:add_usage AND does threshold check. safety.lua
    routes via helpers.on_usage / opts.on_usage callbacks. context.lua
    stays decoupled from renderer.

R6. Preserve nil-vs-0 cost distinction. Accumulator slot gains
    `is_local = true` (sticky) when ANY recorded usage had cost==nil.
    `:cost detail` annotation comes from is_local flag, not a
    fragile cost==0 heuristic.

R7. :cost detail sort needs 3-level deterministic key:
    (cost desc, model asc, category asc) — table.sort is unstable.

R8. call_broker fallback passes opts.include_usage unchanged.
    Documented as known assumption (B1 confirms both backends
    accept; future-broken fallback can pass include_usage=false).

R9. :resume does NOT restore historical usage_totals. Per-turn usage
    IS in session JSONL for scripting; cross-session aggregation is
    Q-C2 deferred. Documented in §8.

R10. $%.4f loses sub-cent precision (cloud cost 0.000028 -> $0.0000).
     Widened to $%.6f in §6 + §7 warn message format.

NITs (APPLIED):

N1. §4 pseudocode comment notes `if doc.usage` branch is independent
    of choice branch (handles both B2 emission shapes).
N2. §2 stale "B7" reference corrected to B3.
N3. §13 commit 3 row gains explicit dependency note on commit 1's R1.
N4. §13 commit 4 spells out llm_probe -> llm_second_opinion ->
    M.is_destructive signature chain widening.
N5. §3 + §13 commit 6 — PHASE0 §11 amendment already in tree
    (3bad07b); commit 6 must NOT re-apply.

PHASE7.md now 803 lines (was 528 after plan). +275/-57. Ready for
implementation phase pending user gate.

marfrit 0f14dc1727 docs/PHASE7: plan — §13 commit roadmap
Status: Analyze -> Plan.

Q-C4 was the last open question pending baseline; now resolved per
B1 (stream_options accepted by both backends; required for local).

§13 Implementation Plan added — 6 commits, bottom-up:

  1. broker.lua: usage extraction from final SSE chunk; build_request
     signature widening to (model_cfg, msgs, stream, opts); on_delta
     ("usage", payload); chat returns (text, usage); opts.category
     passthrough.

  2. context.lua: usage_totals + cost_warn_fired fields; add_usage /
     total_cost / total_tokens helpers; :reset preserves both.

  3. repl.lua: wire opts.category at 5 non-Norris call sites (main,
     delegate x2, summarize, memory_summarize); on_delta("usage")
     branch routes to ctx:add_usage.

  4. safety.lua: wire opts.category for Norris main broker + is_
     destructive LLM probe; helpers.on_usage callback convention
     (no new module dep — matches #52's scrub_msgs pattern).

  5. repl.lua: :cost meta surface + warn-threshold check + HELP.

  6. config.lua: commented cost example block + PHASE7.md status
     bump to Implement.

Per-commit risk index covers signature-change blast radius, missed
call-site lint, and warn-flag one-shot semantics. Lua's multi-
return semantics keep broker.chat backwards-compat automatic.

Two items left open at plan, resolve at implement:
  - is_destructive opts.on_usage vs cfg.helpers threading
  - per-turn verbose mode (deferred; v1 = :cost on demand only)

marfrit 2244a3f1ee docs/PHASE7-baseline: live broker probes for usage shape
Real probes against hossenfelder.fritz.box:8082 against both backends.
Five findings, all align with the formulate/analyze design — no
structural changes.

B1. `stream_options.include_usage = true` is safely accepted by
    both backends. REQUIRED for local llama.cpp to emit usage;
    no-op for cloud (which emits anyway). Default-true is correct.

B2. Two emission patterns observed:
    - Cloud (Bedrock): usage rides the FINAL delta chunk with
      non-empty `choices` carrying finish_reason.
    - Local: usage rides a SEPARATE chunk with `choices: []`
      preceding `[DONE]`.
    Both shapes are handled by the same `if doc.usage then ...`
    check; the existing on_event choices-branch short-circuits
    safely when choices is empty.

B3. `cost` field is dollar-denominated (number) and cloud-only.
    Local returns `timings` instead (perf, not cost). Accumulator
    captures `usage.cost` as-is; nil treated as 0. :cost detail
    annotates local lines so $0 isn't misread.

B4. `doc.model` in the usage event reflects the upstream-API-version
    (e.g., Bedrock rewrites `anthropic/claude-haiku-4.5` to
    `anthropic/claude-4.5-haiku-20251001`). Accumulator keys by
    caller-intended `model_cfg.model`, NOT `doc.model`, for stable
    cross-call comparison.

B5. Usage event is always the LAST data event before `[DONE]`.
    Emission of `on_delta("usage", ...)` happens after curl.post_sse
    returns — one call per stream, after all text + tool_calls.

Q-C4 RESOLVED: hossenfelder forwards `stream_options.include_usage`
to all backends correctly.

marfrit f0bccdec48 docs/PHASE7: analyze — probe broker surface + resolve Qs in-place
Status: Formulate -> Analyze (tree at 3bad07b probed).

11 findings (A1-A11), 5/6 open Qs resolved (Q-C4 deferred to baseline):

A1.  broker.chat_stream surface clean — usage capture via closure-local
     + on_delta("usage") emission after curl.post_sse returns.
A2.  7 caller sites for opts.category threading (probe / norris /
     summarize / main / delegate x2 / memory_summarize).
A3.  build_request signature widens to (model_cfg, msgs, stream, opts)
     to absorb tools / max_tokens / include_usage / stream_options
     without further positional growth.
A4.  Q-C3 RESOLVED: free-form categories (caller decides); matches
     Phase 6 helpers/skills convention.
A5.  Q-C5 RESOLVED: warn fires on the call that crossed (no NEXT-call
     delay).
A6.  Q-C6 RESOLVED: :reset does NOT clear cost_warn_fired; only
     :cost reset clears.
A7.  Norris call-graph rewires (commit 955bd82) — secrets streaming
     rehydrator wraps only "text" kind; new "usage" kind passes
     through unchanged. No new entanglement.
A8.  ctx.usage_totals survives :reset (R8 parity with memory_items,
     project).
A9.  Session JSONL inherits the new field automatically (dkjson
     opaque encoding).
A10. Q-C1 PARTIAL: defensive silent skip when provider omits usage.
     Real probe required for local model — baseline action.
A11. Q-C4 deferred to baseline (real broker probe).

§2 build_request row updated to mention the A3 refactor.
§11 Open Qs table now shows all 6 with resolutions; only Q-C4
remains as a baseline-time probe.

marfrit 3bad07b2da docs/PHASE7: formulate — cost / usage observability
Phase 7 formulate manifest + PHASE0 §11 amendment to add the Phase 7
row (substrate amendment per CLAUDE.md §3, lands in the same commit).

Four pillars:

  1. Usage capture in broker.chat_stream — extract `usage` from the
     final SSE chunk (OpenAI streaming spec with `stream_options:
     {include_usage: true}`). Surface via new on_delta("usage",
     payload) kind. broker.chat returns (text, usage) — backward-
     compat: existing callers ignore the second value.

  2. Per-session accumulator on ctx — ctx.usage_totals[model][category]
     tables (categories: main / delegate / summarize / memory_summarize
     / probe / norris, tagged at the call site via opts.category).
     :reset preserves usage_totals (R8 parity with memory_items /
     project). Session JSONL gains an optional `usage` field on
     assistant turns for after-the-fact analysis.

  3. :cost meta surface — :cost (summary), :cost detail (per-model +
     per-category breakdown), :cost reset (zero the meter). Pure-Lua
     read of ctx.usage_totals; no broker calls.

  4. Optional warn thresholds — cfg.cost.warn_at_dollars /
     warn_at_tokens emit a one-shot status when crossed. Default off;
     useful with cloud presets configured.

Doc covers scope + done-when criteria, tech decisions table, module
changes, per-pillar deep dive with code sketches, UX surface, out of
scope, risks, 6 open questions to resolve in analyze.

Open at formulate:
  Q-C1 — provider-without-usage handling (local llama.cpp probably)
  Q-C2 — cross-session persistence (defer to phase 8)
  Q-C3 — categories closed-set vs free-form
  Q-C4 — does hossenfelder forward stream_options to all backends?
  Q-C5 — warn fires on the call that crosses, or the next one?
  Q-C6 — :reset clears cost_warn_fired too, or only :cost reset?

Scope confirmed via AskUserQuestion: cost/usage observability
(chosen over project-local config overlay and session search/tag).

marfrit 955bd82efb safety + repl: wire secrets into safety.lua (closes #52)
Closes the last #13 gap — Norris broker call + is_destructive LLM
second-opinion probe were the two egress points NOT covered by the
scrub-at-egress design in commit d852aca.

Approach: option (b) per #52's fix sketch — callback-via-helpers/opts.
safety.lua does NOT gain a require("secrets") dependency (acceptance
criteria 3); integration is purely through the convention the rest
of the helpers table already uses.

safety.lua changes:

  - llm_probe gains an opts table. When opts.scrub_msgs is set, the
    {system, user(cmd)} message pair is scrubbed before broker.chat.
    When opts.rehydrate is set, the YES/NO reply is rehydrated before
    parsing (defensive — the verdict shouldn't carry placeholders but
    rehydration is a safe no-op if it doesn't).

  - llm_second_opinion threads opts through to llm_probe.

  - M.is_destructive(cmd, cfg, opts) — opts optional; nil-opts is
    backwards-compatible (no scrub, original behavior).

  - M.norris_step:
      * outbound broker.chat_stream message scrubbed via
        helpers.scrub_msgs(ctx:to_messages(), model_cfg) when provided.
      * on_delta wrapped with helpers.streaming_rehydrator():push /
        :flush so the user sees rehydrated text AND text_parts
        accumulates rehydrated chunks (parity with ask_ai in repl.lua).
      * both M.is_destructive call sites (tool_call probe + CMD: probe)
        now pass probe_opts = {scrub_msgs, rehydrate} when the
        helpers carry them.

repl.lua changes:

  - Norris helpers table gains scrub_msgs / rehydrate /
    streaming_rehydrator closures, all nil-safe (return identity /
    nil when secrets_session is nil).

  - :safety check meta passes probe_opts to is_destructive when
    secrets_session is configured. Without secrets, behavior unchanged.

Unit-test verified end-to-end:
  - Stubbed broker.chat captures the messages it receives.
  - Without opts: probe SEES `ghp_realsecretvalue_...` (control).
  - With opts: probe sees `$AISH_SECRET_NNN` (correct scrub).

PHASE6.md per the review fold-in).

config.lua:
  - Commented-out `project = { auto_tree, tree_depth, tree_max_chars }`
    block with the same shape as the Phase 1-5 example blocks.
  - Note that :diff / :tree / :highlight all work without config; the
    `project` block ONLY controls the startup auto-inject.
  - Note about :highlight v1 having no config flag (runtime-only),
    cross-references the in-REPL install hint.

docs/PHASE6.md:
  - Status header bumped: "Plan + review fold-in" -> "Implement"
  - Lists the 6 implement commits in the header for traceability:
      c4fc7fd  context: compose_project plumbing
      d1dce83  _scan_project_tree + :tree + auto_tree hook

      this    config example + status bump

Phase 6 implementation is complete. Next inner-loop step is verify
(7) — user-driven smoke tests against the live broker on each pillar
plus filing of issues for any defects, then memory-update (8).

marfrit 11d0e599cd repl + renderer: tree-sitter highlighter (Phase 6 commit #5)
The largest Phase 6 commit — fence-aware stream filter in renderer.lua
+ external tree-sitter dispatch + :highlight meta in repl.lua.

renderer.lua — fence-aware filter wrapping assistant_delta:

  M.set_highlight(enabled, detected, highlight_fn)
      Called by repl.lua at startup AND on every :highlight toggle.
      Stores state in module-locals (off by default).

  State machine inside _hl_push:
    outside: pass chunks through; HOLD trailing partial-fence chars
             (per R1 — local llama.cpp splits ```python as `'``'`
             then `'`python\n'`, so naive pass-through drops the
             leading "``" and never recovers).
    inside:  buffer cumulatively until "\n```" appears; emit
             highlight_fn(body, lang) then the closing fence verbatim.
             Recursive call handles "rest" after the closing fence.

  N1: fences only open at start-of-stream OR after a newline
      (`^```` or `\n```` only). Inline backticks in prose
      ("use ``` to mark code") do not open a fence.

  R3 (PTY raw-mode toggle per highlight call): no change here — every
      executor.exec call already toggles raw-mode (existing behavior
      since Phase 1). The risk is theoretical; smoke-test interactively
      after install if multi-fence renders show flicker.

  assistant_flush handles end-of-stream gracefully: drains any held
  partial-fence tail OR an unterminated inside-fence buffer.

repl.lua — _detect_treesitter + highlighted + :highlight meta:

  _detect_treesitter()  one-shot popen probe of `tree-sitter --version`.
                        Run once at startup; cached as
                        highlight_detected.

  highlighted(body, lang_tag)   R2-placed in repl.lua (has _shq +
                                executor access). Translates the fence
                                tag (`py`, `python`, `lua`, etc.) to
                                a canonical lang via LANG_TAG, picks
                                the canonical extension via LANG_EXTENSION,
                                writes body to a tmpfile with that
                                extension, runs `tree-sitter highlight
                                <tmpfile>` via executor.exec, returns
                                the output. On ANY failure (CLI absent,
                                non-zero exit, empty output), returns
                                `body` unchanged — silent pass-through.

  R4 RESOLVED VIA REAL INSTALL: probed `tree-sitter highlight --help`
      on noether; confirmed:
        - NO `--lang` flag exists (formulate-time assumption wrong)
        - takes a PATH; language inferred from file extension
        - alternative `--scope source.X` exists but also unreliable
          without configured grammars
      Resolution: write tmpfile with `os.tmpname() .. LANG_EXTENSION[lang]`
      and pass the path. Matches the documented upstream contract.

  B4-followup: even with the CLI installed, highlighting requires
      `~/.config/tree-sitter/config.json` parser-directories with
      cloned + built `tree-sitter-<lang>` grammars. Without parsers,
      every call exits non-zero and we silently pass through. The
      :highlight install hint surfaces all three install steps so the
      user knows what's actually needed.

  :highlight [on|off|status] meta:
      no arg     -> flip
      on/off     -> set explicit
      status     -> report toggle + CLI detection state
      When toggled on AND CLI absent: emit a 4-line install hint
        (CLI install, init-config, grammar clone reminder).
      When toggled on AND CLI present: emit a 1-line note that
        parser-directories must be set up for actual highlighting.

HELP gains :highlight entry.

Tested:
  10/10 unit cases on the renderer state machine, including:
    - plain prose passthrough
    - single-chunk fence
    - B2 split fence ("``" + "`python\n" + "x=42" + "\n```")
    - N1 SOL anchor (mid-line ``` does not open)
    - trailing \n properly emitted across chunks
    - SOL-only fence open
    - prose after closing fence preserved
    - two fences in one stream
    - highlight off = passthrough (callback never fires)

  E2E :highlight meta verified:
    :highlight status -> off / detected
    :highlight on     -> toggles + emits parser-dir reminder
    :highlight status -> on / detected
    :highlight off    -> off

marfrit 0d63f01601 repl: expand_mentions tiered @<r1>..<r2> diff retry (Phase 6 commit #4)
Per A6 (tiered resolution): @<token> tries file lookup first; if the
file doesn't exist AND the token contains "..", retry as a git
ref-range and substitute with a fenced `diff` block. Preserves the
existing peel-on-trailing-punct logic (e.g., `@HEAD~1..HEAD,` peels
the comma, resolves the ref, restores the comma after the closing
fence).

Resolution order for @<token>:
  1. io.open(token, "rb")    -- file lookup, with trailing-punct peel
  2. if (1) fails and token contains "..":
        git --no-pager -c color.ui=never diff <r1>..<r2>
     on exit 0 + non-empty body: substitute as ```diff fenced block
  3. else: leave literal `@token` + emit "[aish] @X: not found" status

Examples:
  @README.md            -> file (path branch)
  @../sibling.txt       -> file (path branch; `..` only triggers retry
                                 when path lookup FAILS, so existing
                                 paths with `..` segments are unaffected)
  @HEAD~1..HEAD         -> diff (path fails, ref succeeds)
  @origin/main..feature -> diff (path fails — no such literal file;
                                 ref succeeds; `/` in ref is fine because
                                 we don't use the path's `/`-absence as
                                 a discriminator)
  @nonsense..gibberish  -> literal preserved (both fail)

Required restructuring:
  - _shq and _git_clean_cmd lifted from M.run closure scope to module
    scope (above expand_mentions). Single source of truth for the
    B1 prefix shared with commit #3's :diff. The in-M.run duplicates
    are removed.
  - expand_mentions now references `executor` (already required at
    module scope on line 7) for the diff retry.

Status messages updated:
  - File expansion: "@<path> expanded (N bytes, truncated)"  (existing)
  - Diff expansion: "@<path> expanded (N bytes, diff)"        (new)

Tested with the 7 existing #7 cases + 7 new diff-retry cases (14/14):
  ref-range expansion shape, body contains `diff --git`, trailing
  prose preserved, @../path stays as file (not diff), neither-path-
  nor-ref preserves literal, trailing-comma peel composes with ref
  retry.

marfrit 4d5f93aaa5 repl: :diff meta + _git_clean_cmd helper (Phase 6 commit #3)
User-driven git diff injection. The model sees the diff on the next
ask_ai turn through the existing exec_output channel.

Changes:
  - _git_clean_cmd(subcmd_and_args) helper near _scan_project_tree.
    B1: every git invocation that flows into context MUST use
    `--no-pager -c color.ui=never`. Forkpty makes git think stdout
    is a TTY, enabling both color and the pager's keypad/line-clear
    escapes — these would pollute the captured context block. The
    helper is the single chokepoint; commit #4's @<r1>..<r2> retry
    will reuse it.

  - :diff [<args>] meta:
      - Reads cwd at meta invocation (R6: differs from :tree's
        scan-time cwd capture; documented in §5).
      - Runs `_git_clean_cmd("diff " .. args)` via executor.exec.
      - Empty output -> "(no diff): <label>" status, no context append.
      - Non-zero exit -> "diff failed (exit N): <label>" status,
        no context append. git's stderr already streamed to the
        user via executor.exec's live multiplex, so the failure
        reason is visible.
      - Success -> appends "[diff <label>]\n<output>" via
        ctx:append_exec_output. Label is "(working tree)" for empty
        args, else verbatim args.
      - Status confirms injection size: "diff injected: <label> (N bytes)".

  - HELP gains :diff line with three example arg shapes; N3-resolved
    (no `staged` alias — the meta is thin pass-through to git's grammar).

Smoke verified across four scenarios in an ephemeral test repo:
  - Working-tree dirty -> 110-byte diff injected, no ANSI escapes
  - --cached -> 118-byte staged diff injected, clean
  - garbage..nonexistent -> exit 128, status + skip
  - Clean working tree -> "(no diff)", status + skip

marfrit d1dce832da repl: _scan_project_tree + :tree meta + auto_tree (Phase 6 commit #2)
First user-visible Phase 6 verb. Builds on commit #1's compose_project
plumbing — sets ctx.project from either the :tree meta or the
cfg.project.auto_tree startup hook.

Changes:
  - _scan_project_tree(dir, opts) helper near _run_hook:
      git -C <dir> ls-files --cached --others --exclude-standard
      when <dir> is inside a git repo (N4: no subshell);
      find <dir> -mindepth 1 -maxdepth <depth+1> -type f
      -not -path '*/.*' otherwise.
    Returns (body, info={file_count, truncated, in_git}). Sorted
    paths, truncated to max_chars (default 4096 per cfg).

  - :tree [<depth>|refresh|off] meta:
      no arg     -> scan with config defaults; resets _project_opts
      <N>        -> scan with depth=N; caches as _project_opts
      refresh    -> re-scan with cached _project_opts (else defaults)
      off        -> clear ctx.project AND ctx._project_opts (R5)
    Status line reports file count + truncation flag + which backend
    fired (git/find).

  - cfg.project.auto_tree startup hook before the main loop:
      if true, scan libc.getcwd() once and set ctx.project.
      Failures status-logged once; REPL continues. Default off
      (existing configs unchanged).

  - HELP updated with three :tree lines.

Plan §12 deliberately defers the config.lua example block to commit #6
along with the status header bump (R9 single-owner).

Smoke (aish repo cwd):
  - :tree no-arg            -> "33 files (git ls-files)"
  - :tree refresh           -> same
  - :tree off               -> "project tree cleared"
  - :tree 1                 -> rescans
  - cfg.project.auto_tree=true at startup -> auto-injected status visible

marfrit c4fc7fde01 context: [project] block plumbing (Phase 6 commit #1)
Foundation for Phase 6 — adds the field + composer + composition
order with no callers yet. Nothing sets ctx.project; the meta hookup
and startup auto-inject land in commit #2.

Changes:
  - Context.new gains `project` (string, nil) and `_project_opts`
    (cached scan opts for `:tree refresh`; R7).
  - compose_project(text) helper mirrors compose_background /
    compose_summary. Returns "" for nil/empty; otherwise emits
    "\n\n[project]\n" + text.
  - to_messages inserts compose_project BETWEEN compose_background
    and compose_summary so the model reads memory facts -> project
    tree -> earlier conversation -> NORRIS suffix.
  - Same Norris-suppression guard as the other two dynamic blocks
    (R-C1 / R-C4 parity; planner stays on goal anchor).
  - Context:reset preserves ctx.project (R8 — matches the Phase 4
    memory_items rule; startup-injected facts survive a user-driven
    context reset).

Smoke verified (14/14 inline cases):
  - project nil -> no [project] block in sys_content
  - project set -> block present with contents
  - ordering: [background] < [project] < [earlier conversation summary]
  - norris_active suppresses all three; NORRIS suffix still appears
  - :reset clears turns/pending_exec_output/summary; preserves
    memory_items AND project

marfrit 261b230be8 docs/PHASE6: review fold-in — 2 BLOCKERs resolved, 7 CONCERNs, 6 NITs
Independent agent review of PHASE6 (manifest + baseline + plan at
4407029). Status header: Plan -> Plan + review fold-in.

BLOCKERs (RESOLVED in-place):

R1. §4 fence detector's `outside`-state dropped the leading `'``'`
    chunk of a split fence — contradicted B2's local-model
    split-fence requirement (4-char median chunk size). Algorithm
    rewritten: outside-state now holds a tail (up to 10 chars) when
    the chunk's suffix could be a fence prefix; flushes on next push.
    Same accumulator pattern as the secrets streaming rehydrator.

R2. `highlighted()` file placement was ambiguous (§3 vs §12). Lives
    in repl.lua (where _shq and executor are accessible);
    renderer.lua exposes set_highlight(enabled, detected, highlight_fn)
    and calls back. Keeps renderer.lua free of the executor require.

CONCERNs (FOLDED):

R3. PTY raw-mode toggle on every code-block render — smoke-test for
    cursor flicker / SIGWINCH races before locking in. Risk row 5.
R4. tree-sitter highlight --lang X grammar is UNVERIFIED — upstream
    CLI canonically takes a path with extension. Implement-time
    check required; fallback path documented (extension-based
    tmpfile + path arg). Added to risk row 5 + open-at-plan.
R5. :tree off semantics clarified — one-shot clear of ctx.project
    + ctx._project_opts; no "disabled" flag.
R6. cwd-coupling difference between :diff (call-time) and :tree
    (scan-time) now documented in §5.
R7. :tree refresh opts caching specified — caches ctx._project_opts;
    `:tree refresh` reuses last explicit opts.
R8. :reset preserves ctx.project (parity with memory_items per
    Phase 4). §12 commit 1 smoke updated.
R9. Status-bump duplication between §12 commits 5e and 6 resolved
    — commit 6 owns the bump.

NITs (APPLIED):

N1. §4 algorithm pseudocode now includes SOL/post-newline anchor
    (mid-line backticks in prose don't open a fence).
N2. _detect_treesitter() gained a comment explaining the popen
    pattern doesn't gate on exit code (B3).
N3. :diff staged shorthand dropped — meta is a thin pass-through
    to git's own grammar.
N4. _scan_project_tree switched from `cd && git ...` to
    `git -C <dir> ...` — no subshell, more idiomatic.
N5. Open-at-plan dir-arg bullet dropped (already decided in §6);
    replaced with R3 + R4 implement-time verification items.
N6. §11 wording on #52 left as-is (cosmetic only).

PHASE6.md now 896 lines (was 701 after plan). +264/-69. Ready for
implementation phase 6 of the inner loop pending user gate.

marfrit 4407029296 docs/PHASE6: plan — fold B1/B3/B4 + add §12 commit roadmap
Status header: Analyze -> Plan.

Baseline findings folded into the design sections:

  §1 (highlighter pillar) gains B4: tree-sitter absent on every
  probed host; :highlight on emits install-hint when missing.

  §4 (highlighter sketch) revised per B3: io.popen():close() doesn't
  expose exit codes in LuaJIT. Route via executor.exec("cat tmp |
  tree-sitter ...") which uses pty.spawn+waitpid and returns code
  reliably. Tmpfile design retained (avoids ARGMAX + shell-escape).

  §5 (:diff impl + @<r1>..<r2> retry) revised per B1: every git
  invocation must use `--no-pager -c color.ui=never` to suppress
  the color/keypad/line-clear escapes forkpty triggers. Factored
  recommendation: helper `_git_clean_cmd(subcmd)` shared by :diff
  and the @-mention diff retry.

New §12 Implementation Plan — 6 commits, bottom-up:

  1. context.lua: ctx.project + compose_project + composition order
  2. repl.lua: _scan_project_tree helper + :tree meta
  3. repl.lua: :diff meta + _git_clean_cmd helper (B1)
  4. repl.lua: expand_mentions tiered resolution (@<r1>..<r2> per A6)
  5. renderer.lua + repl.lua: tree-sitter detect + fence filter +
     :highlight meta (B3-revised tmpfile dispatch)
  6. config.lua project example + status -> Implement

Per-commit risk index + smoke criteria. Highlighter (commit 5) is
the largest experimental surface — placed last so the rest of Phase 6
ships even if highlighter slips. Order is independent enough that
swapping 3<->4 or 5<->6 doesn't break anything; bottom-up keeps each
commit individually green.

Things deliberately not split: _shq reuse, lang map duplication for
v1, streaming-rehydration order (rehydrate -> highlight -> emit
inherits naturally from existing chunk pipeline).

Two items open at plan time, resolve at implement: _scan_project_tree
dir-arg vs hardcoded getcwd; :highlight status probing
tree-sitter --print-langs.

marfrit 9f50206ca6 docs/PHASE6-baseline: substrate probes ahead of implementation
Six findings from probing the world before tree-sitter / diff / project
tree implementation lands:

B1. `git` subcommands through executor.exec emit ANSI color + DEC
    keypad/line-clear escapes by default (forkpty enables interactive
    mode). `:diff` impl MUST use `git --no-pager --color=never <args>`.
    Same flags apply to any future git verbs.

B2. SSE chunk size envelope: local llama.cpp delivers tiny chunks
    (median 4 chars, max 13) AND splits code fences across boundaries
    (`'``'` then `'`'`). Cloud (Anthropic via OpenRouter) delivers
    big chunks (median 26 chars), fences intact. The §4 fence-aware
    filter accumulator design covers both — confirmed necessary by
    local-model behavior.

B3. **LuaJIT io.popen():close() does NOT return exit codes** — Lua
    5.1 contract, not 5.2+. Breaks the A4 highlighter resolution.
    Revised: route via `executor.exec("cat tmp | tree-sitter ...")`
    which uses pty.spawn + waitpid and returns (out, code) reliably.

B4. tree-sitter CLI absent on both probed hosts (noether, higgs).
    Highlighter is opt-in by design; absent-CLI path should emit a
    clear install hint, not silently no-op.

B5. Project-tree envelope: aish 32 files / 449 chars; similar local
    repos 15-25 files; scan time ~1-5ms. The 4096-char default cap
    accommodates ~290 typical paths. Large repos handled via
    tree_depth or cap tuning per existing §9 risk row.

B6. os.tmpname returns POSIX /tmp/lua_XXXXXX paths; acceptable for
    the B3-revised tmpfile-roundtrip pattern.

No structural changes to formulate/analyze. B1, B3, B4 will fold into
PHASE6.md §4 / §5 / §1 during plan.

marfrit ad52fe4538 docs/PHASE6: analyze — substrate probes + Q resolutions in-place
Analyze pass against tree at f596743. All 6 formulate-time questions
resolved without structural changes; pillar shapes intact.

A1. renderer.lua surface clean — assistant_delta/flush accumulate via
    stream_buf; fence-aware filter slots in between chunk receipt and
    emit without touching anything else.

A2. executor.exec via pty.spawn already handles git diff / find;
    cwd-aware (inherits from libc.chdir). No new IO model.

A3. context composition order locked: base + [background] + [earlier
    summary] + NORRIS. [project] inserts between [background] and
    [earlier summary]; Norris-suppression guard inherited.

A4. Q-H1 RESOLVED: tmpfile roundtrip for tree-sitter popen3
    (io.popen("w") + redirect stdout to tmp file; io.open reads back).
    Avoids ARGMAX + shell-escape complexity. Cost ~one syscall per
    code block.

A5. Q-D1 RESOLVED: no confirm gate on :diff. git diff is read-only;
    matches :history / :sessions / :safety check.

A6. Q-D2 RESOLVED: tiered @<token> resolution — file lookup first,
    then ref-range retry when path fails AND token contains "..".
    @origin/main..feature works naturally; @../sibling.txt unaffected.

A7. Q-H2 RESOLVED: highlighter is assistant-output only in v1.
    @-mention echo via readline is a different code path; deferred
    to v2 (added to §8 out-of-scope).

A8. Q-T1 RESOLVED: project tree captured at scan time, not auto-
    refreshed on cd. v1 verb is :tree refresh; cd-intercept auto-
    refresh deferred to v2.

A9. Q-T2 RESOLVED: .gitignore via `git ls-files --exclude-standard`
    in repos; find fallback outside. Custom globs deferred to v2.

A10. expand_mentions punct-peel doesn't strip "/", so HEAD~1..HEAD,
     peels comma cleanly and the diff retry catches the cleaned token.

A11. Auto-injection ordering: memory load → tree scan → first ask_ai.
     Composition reads memory facts before file tree.

A12. [project] Norris-suppressed (parity with R-C1/R-C4).

§3 module-changes table: context.lua row updated (project string +
compose_project + ordering note + Norris suppression). §4 highlighter
code sample replaced with the tmpfile-roundtrip resolved form. §5
@-mention section rewritten as tiered-resolution with worked examples.
§8 out-of-scope gained three v2-polish items (echo highlight, cd-
intercept auto-refresh, custom globs) so they're tracked. §10 Open
Questions table now shows all 6 Qs with their resolutions inline.
§9 Risks row for @-mention collision updated to point at A6.

marfrit f596743834 docs/PHASE6: formulate — tree-sitter highlight + diff + project tree
Phase 6 formulate manifest. Three pillars per PHASE0 §11 row 6:

  1. Tree-sitter syntax highlighting hooks
     External `tree-sitter` CLI when present, no-op otherwise.
     Honors PHASE0 §3 (no compiled extensions). Toggleable
     at runtime; off by default so existing UX is unchanged.

  2. Diff-aware code injection
     :diff [args] meta + @<ref1>..<ref2> @-mention extension.
     Shells out to `git diff`; output flows through the existing
     exec-output context channel.

  3. Project-level file-tree context
     :tree meta + optional cfg.project.auto_tree startup inject.
     git ls-files in a repo, find fallback otherwise. Composed
     into the system prompt as a new [project] block between
     [background] and [earlier summary]. Suppressed under Norris
     (R-C1 / R-C4 parity).

Module changes: renderer.lua (fence-aware highlight filter), context.lua
(compose_project), repl.lua (3 new metas, 3 new helpers, expand_mentions
extension). No new module files in v1.

Doc covers: scope + done-when criteria, tech decisions table, module
changes table, per-pillar deep dive with example code, UX surface
summary, out-of-scope list, risks, and 6 open questions to resolve
in analyze (Q-H1/Q-H2 highlighter, Q-D1/Q-D2 diff, Q-T1/Q-T2 tree).

Scope confirmed via AskUserQuestion: all three subsurfaces in scope;
tree-sitter approach is external CLI w/ no-op fallback.

marfrit d852acadc2 repl: wire #13 secrets — scrub outbound, rehydrate stream + tool args
Plumbs the secrets.lua module (commit e4b818b) into the conversation
pipeline. Hook points:

  ask_ai          — scrub_messages(ctx:to_messages(), mode) before
                    call_broker; rehydrate streamed deltas via
                    streaming_rehydrator so the user sees real values
                    while text_parts accumulates rehydrated chunks
                    (final_resp is plain — CMD: / DELEGATE: extractors
                    see plain values)

  MCP dispatch    — dispatch_tool_call rehydrates the args table before
                    sess:call_tool so the trusted MCP server receives
                    real values (the model emitted placeholders because
                    it saw a scrubbed context)

  DELEGATE: & :delegate
                  — scrub sub_msgs before broker.chat; rehydrate sub_text
                    before appending to context, so future turns see
                    real values restored

  Phase 5 summarize-on-evict
                  — scrub sum_msgs before broker.chat; rehydrate the
                    reply that becomes ctx.summary

  :memory summarize
                  — same scrub + rehydrate pair

Mode resolution per call: model_cfg.redact → config.secrets.default →
"vault+autodetect" if vault loaded, else "off".

ctx storage convention: PLAIN values throughout. The scrub happens at
the egress (broker call) per the active redact mode; ctx.turns never
holds placeholders for content the user typed or executor produced.
The model's own emissions (assistant tool_call arguments) may carry
placeholders because the model saw the scrubbed context — rehydrated
at MCP dispatch and otherwise harmless on re-serialization (idempotent
re-scrubbing).

New meta:
  :secrets [status]         vault entries, placeholders allocated this
                            session, active broker mode. Never prints
                            actual values (vault file is itself a
                            secret per gotcha 7).
  :secrets check <text>     dry-run scrub against the active broker's
                            mode — shows the output transformation.

Documented in config.lua with a commented-out block + per-broker
redact field example.

Deferred to a follow-up issue (clearly scoped):
  - safety.lua broker call sites (Norris main loop, is_destructive
    LLM second-opinion probe) — same wiring pattern, but they don't
    currently see secrets_session; needs threading through helpers.
  - @-mention file content is appended PLAIN to ctx and scrubbed at
    egress alongside the rest of the user turn (covered by the
    ask_ai scrub).
  - exec output streamed live to terminal is pre-scrub (user sees
    real values in their own shell — by design); the captured-for-
    context copy is scrubbed at egress alongside the rest.

This is the "full scope" implementation chosen via AskUserQuestion.

marfrit e4b818b0e9 secrets: vault loader + scrub/rehydrate + autodetect (#13 commit 1)
Standalone module — no wiring yet. Lands the substrate for issue #13:

  secrets.load(path)            — vault file loader; refuses non-0600
  secrets.make_session(vault)   — per-conversation scrub/rehydrate state
  session:scrub(text, mode)     — substitute literals (+ autodetect)
  session:rehydrate(text)       — restore placeholders
  secrets.streaming_rehydrator  — chunk-boundary-tolerant streaming wrapper

Mode semantics (chosen per call by the caller):
  "off"               — identity, no mapping
  "vault"             — vault literals only, placeholders, rehydratable
  "vault+autodetect"  — + heuristic regexes, placeholders, rehydratable
  "stealth"           — + heuristic regexes, opaque decoys, one-way

Placeholders are stable across the session: the same literal always
maps to the same $AISH_SECRET_NNN slot, so re-scrubbing the same
context is idempotent and the model sees a consistent vocabulary.

AUTODETECT_PATTERNS (ordered; longer prefixes first):
  sk-or-v<N>-...  OpenRouter
  ghp_/gho_/ghs_  GitHub PATs
  AKIA<16>        AWS access keys
  eyJ...x.y.z     JWTs
  sk-...          OpenAI (generic; matched after openrouter)
  -----BEGIN ... PRIVATE KEY-----  SSH/GPG key headers

Streaming rehydrator: tolerates a placeholder split across SSE chunks
($AISH_SE then CRET_001). It holds back the trailing partial-match
in a buffer, emits the rest, and resolves on the next push or flush.
Verified with 20 unit cases (vault sub, stable mapping, autodetect
across all label kinds, stealth decoys, mode=off, streaming with
mid-placeholder splits, non-placeholder $-prose pass-through).

Vault file mode enforcement: 0600 only — matches ssh's behavior for
~/.ssh/id_rsa. Loud failure (status + skip) if mode is wider.

Next commit (issue #13 follow-up): wire into broker / tool dispatch
/ display, add per-broker `redact` policy, :secrets meta, config
example block.

marfrit cdf4e86679 repl: sub-broker delegation via DELEGATE: marker (closes #6)
Cost and context-window control: a "heavy" preset's model can offload
work to a cheaper preset without spending its own tokens on the result.
Example: deep model is mid-conversation and asks fast to summarize a
20k-line build log; the summary comes back as exec-output for the
next turn, deep stays small.

Marker syntax: DELEGATE: <preset> "<prompt>"

(Single or double quotes; one DELEGATE per line; lines without the
quoted shape are dropped — let the user write about delegation in
prose without accidental dispatch.)

Dispatch flow (mirrors CMD: / CMD&: extraction):
  1. ask_ai's stream completes
  2. extract_delegate_lines walks the final response
  3. For each {preset, prompt}: broker.chat(config.models[preset], ...)
     synchronously; result is appended via ctx:append_exec_output as
     "[delegate <preset>]: <result>"
  4. The model sees the delegate result on its next turn

Implementation choice — marker over tool: option 1 from the issue
("inline delegate marker") works with any model regardless of
tool_calls support. Option 2 (aish_delegate as a tool dispatched in
the existing Phase 2 sub-loop) is the better UX for capable models
since it returns the result mid-turn — filed as follow-up if needed.

Meta surface:
  :delegate <preset> <prompt>   one-shot direct invocation (useful for
                                testing without depending on the model
                                emitting DELEGATE:, and as a manual
                                "ask <preset> something" verb)

Scope:
  - Plan mode: emits "PLAN: DELEGATE <preset> <prompt>" without dispatch
  - Norris: not extended; the planner's model anchor would conflict with
    mid-plan switching (R-C3-adjacent risk)
  - No self-delegation guard: each DELEGATE is a separate broker call,
    not recursive; a delegate result reaching the next turn could
    contain another DELEGATE but that's bounded by max_tool_depth-style
    iteration cap on the parent
  - No cost prompt: configuring a paid cloud preset already implies
    consent to spend on it
  - Unknown preset → error status + exec-output note "[delegate X failed:
    unknown preset]"

Extractor unit-tested with 8 cases (single-quote, double-quote, multi-
line prose, empty prompt, no-quotes, case-sensitive, wrong prefix).

marfrit f94d16fc89 repl: background CMD&: with handle/poll (closes #8)
Builds, long-running network calls, and file watches no longer block
the turn. A new "CMD&: <cmd>" marker (analogue of CMD:) tells the REPL
to spawn the command in the background, return immediately, and poll
for completion between user inputs.

Process model: shell-wrapped to avoid needing fork()/execv() FFI.

  nohup sh -c '(<cmd>) > <log> 2>&1; echo $? > <status>' </dev/null
       >/dev/null 2>&1 & echo $!

The child is reparented to init; we hold only the PID and the path to
the .status sidecar. Completion is detected by the .status file
existing (the wrapper writes it as its last act). No waitpid needed —
the child isn't ours after the popen subshell exits.

Storage: <history.dir>/bg/<id>.log + <id>.status. The directory is
created lazily at startup (mkdir -p). Requires history.dir to be
configured; without it CMD&: emits an error status and the model
sees an "[bg failed to start]" exec-output note.

check_bg_done() runs at the top of each main-loop iteration alongside
check_every_due(). When a job is detected as exited, the REPL:
  - emits a status line "[bg:<id> exited <code>, <bytes>, <secs>s wall] <cmd>"
  - appends the same string to ctx as exec output, so the model sees
    the completion on its next turn (natural follow-up: "ok the build
    finished; let me check the log")

Meta surface:
  :bg-spawn <cmd>       start a bg job directly (no AI needed; also
                        useful for testing without depending on the
                        model emitting CMD&:)
  :bg-list              show running/done jobs (id, pid, state, runtime, cmd)
  :bg-output <id>       dump the log file to stdout
  :bg-kill <id>         SIGTERM (note: only delivers if the PID is
                        still the actual command — long-lived shells
                        may need pkill by name)

Scope (deliberately limited for v1):
  - No callback-mode readline: bg completion detection is pre-prompt,
    not mid-readline. If a build finishes while the user is typing,
    notification comes when they hit Enter.
  - Permission policy DSL (#9) does NOT apply to CMD&: — the
    asynchronous gating model wasn't designed for the y/N flow.
    Filed as follow-up if needed.
  - Norris not extended: helpers.exec_cmd is still synchronous; the
    planner doesn't dispatch bg jobs.
  - Plan mode interaction: CMD&: in plan mode emits "PLAN: & <cmd>"
    and a "[plan] would bg-run: <cmd>" exec-output note, no spawn.

marfrit 67d80e1047 repl: :every recurring prompts via pre-prompt due-check (closes #11)
In-session timer that re-injects a prompt every N seconds. "Watch this
thing" workflows (`:every 5m "check journalctl -u nginx for errors"`)
without spawning a separate aish process.

Approach: minimum viable. check_every_due() runs at the top of each
main-loop iteration — timers fire BETWEEN user inputs, not during
readline waits or active broker calls. Mid-stream firing would require
rewriting ffi/readline to callback mode (substantial scope). If the
on-the-fly firing requirement matters in practice it can land as a
follow-up issue against the readline FFI.

Meta:
  :every <interval> <prompt>   schedule (interval: 30s | 5m | 2h | bare int)
  :every list                  show jobs (id, interval, time-until-next, model, prompt)
  :every cancel <id>           remove

Defaults:
  - Model: "fast" preset if defined in config.models, else active model
    (per the issue's "recurring prompts should default to fast preset").
  - In-memory only — jobs don't persist across restarts.
  - Suppressed while ctx.norris_active (planner stays on goal anchor).
  - Quotes around the prompt are stripped if present.
  - Each tick fires the job once, re-schedules next_fire = now + interval
    (no catch-up if the interval elapsed multiple times during a long
    user input).

Tested: 11 interval-parse cases (30s, 5m, 2h, bare int, malformed),
load via require, end-to-end :every list / cancel surface.

marfrit 17e62c0326 safety: permission policy DSL — allow/confirm/deny rule lists (closes #9)
The confirm_cmd boolean was too coarse: true interrupts every harmless
ls; false ungates everything. Most workflows want trust for read-only
ops while still gating writes/network/sudo.

New config:

    permissions = {
        allow   = { "^ls%s", "^cat%s", "^git status" },
        confirm = { "^rm%s", "^git push", "^docker%s", "^sudo%s" },
        deny    = { "^ssh%s+root@", "^curl%s+http[^s]" },
    }

Verdict order: deny > confirm > allow. First match in the chosen
category wins. Unmatched defaults to "confirm". Patterns are Lua
patterns (not regex) per PHASE0.md §3 — no compiled extensions.

Verdict behavior in the interactive CMD: loop:
  - allow   → run without prompt
  - deny    → status line, skip
  - confirm → [y/N] prompt (same UX as legacy confirm_cmd=true)

Backward compat:
  - permissions unset + confirm_cmd=true  → always confirm
  - permissions unset + confirm_cmd=false → always allow
  - permissions set                        → policy table is authoritative

Scope deliberately limited to the interactive AI-suggested CMD: gate.
Norris autonomous mode keeps its own safety.is_destructive machinery
(combining the two would double-gate or replace the LLM probe — both
non-obvious behavioral changes that belong in their own issues).
User-typed shell-routed lines (`router.classify → "shell"`) and
:exec also bypass the policy by design — those are direct user intent.

New introspection:
  :perms list           — show the configured rule lists
  :perms check <cmd>    — report verdict + matching rule (debug)

safety.classify_command is exported and unit-tested with 12 cases
covering each category, priority order (deny > allow on overlap),
and both fallback paths.

marfrit 518c01a9f5 repl: user-defined skills loader (closes #2)
PHASE0.md §5.2 froze the meta-command set at compile time. Skills let
the user package repeatable workflows (project queries, prompt
templates, audit routines) without forking aish.

Discovery: scan ~/.config/aish/skills/*.lua at startup (or whatever
$AISH_SKILLS_DIR points at — used both by users with non-XDG layouts
and by CI). Each module exports:

    return {
        name        = "<meta-cmd-name>",     -- must match [%w_-]+
        description = "<one-line>",          -- shown by :skills
        run         = function(args, h) ... end,
    }

Helpers passed to run():
    h.ask(text)   — same path as :ask (with @path expansion)
    h.status(s)   — emit "[aish] s"
    h.exec(cmd)   — run a shell command (subject to plan_mode, hooks)
    h.model()     — current active model name
    h.ctx         — raw Context object (advanced)
    h.config      — the loaded config table

Validation rejects modules that miss name/run, use whitespace in the
name, or collide with an existing meta command (built-in or earlier
skill). Each rejection emits a status line so the user sees why a
skill didn't appear.

New meta command :skills lists what's loaded (sorted, with description).

marfrit fb15f7a690 repl: pre/post CMD hooks via config.hooks (closes #3)
Optional shell scripts trigger around every CMD: execution. Use cases:
audit logging, auto-format-after-edit, custom safety gates beyond the
existing confirm_cmd boolean.

Config shape:

    hooks = {
        pre_cmd  = "/path/to/pre-script",
        post_cmd = "/path/to/post-script",
    }

Contract per hook invocation:
  - The command line is piped to the hook on stdin.
  - Env vars: AISH_CMD (the command), AISH_TURN (#ctx.turns at the
    moment of dispatch), AISH_CWD (libc.getcwd() result).
  - Hook stdout is streamed live to the terminal via executor.exec
    (so the user sees its output regardless of exit status).

Pre-hook: non-zero exit aborts the command and emits a status line
including the exit code. last_exec_code is set to the hook's exit
so the {last_status} prompt template variable reflects the abort.

Post-hook: exit code is ignored (the spec says so); only the visible
stdout matters. Runs after the command's exec_end frame.

Tested with success, abort, and stdin-matches-env paths.

marfrit d738f339cb repl: configurable prompt template via config.shell.prompt (closes #10)
At-a-glance situational awareness: see the active model, context fill,
mode flags, and cwd in the prompt itself — prevents "wait, am I still
in plan mode?" surprises.

Example config:

    shell = {
        prompt = "[{model} {ctx_used}/{ctx_max}t T{turn} {mode}] {cwd_short} > ",
    }

Variables (substituted via {name}):
  {model}        active preset name
  {ctx_used}     char/4 token heuristic (Phase 0 §8; accurate is Q1)
  {ctx_max}      config.context.token_budget
  {turn}         #ctx.turns
  {cwd}          libc.getcwd() (chdir-aware; PWD env may drift)
  {cwd_short}    cwd with $HOME -> ~
  {last_status}  last exec exit code, "" if none yet
  {mode}         "norris" | "plan" | "normal"

Default behavior unchanged when shell.prompt is unset — keeps the
"[aish:<model>]>" form with norris  and plan markers.

Side wiring:
  - ffi/libc.lua gains getcwd() (chdir() doesn't update PWD).
  - run_shell records exit code into last_exec_code for {last_status}.

marfrit 10d2501cff repl: peel trailing punctuation from @path mentions (#7 follow-up)
Natural-language prose like "look at @README.md, then..." or
"@foo.lua." at sentence end previously failed to expand because the
trailing comma/period was included in the path.

Now: if the raw token doesn't resolve, peel trailing chars from
[.,;:?!)] one at a time until the path resolves or no more peels are
possible. On success, the peeled chars are emitted verbatim AFTER the
closing fence so the original punctuation is preserved.

Surfaced during higgs smoke test (TC: "say the first line of
@README.md, then stop" — the trailing comma broke resolution).

marfrit bb374c2ad2 repl: @path mention expansion in input lines (closes #7)
Saves the user from manual copy/paste: typing "show me @repl.lua" or
"compare @config.lua and @config.example.lua" auto-expands each mention
to a fenced code block carrying the file contents, language-tagged by
extension, and feeds the composed text to the broker.

Wired on the "ai" branch of the input loop and inside :ask. Meta and
shell branches pass through unchanged — "@foo" in shell context is a
literal program argument; meta commands store text verbatim.

Trigger rule: "@" must follow start-of-string or whitespace — avoids
false positives on email addresses ("user@example.com") and shell
short-options. Path extends to next whitespace.

Other behavior:
  - Language tag derived from extension via a small lookup; unknown
    extensions yield an untagged fence.
  - Files over 32 KB are truncated head/tail (16K + 8K) with a marker.
  - Missing files leave the literal "@path" token in place and emit
    a "[aish] @path: not found" status — non-fatal, lets the user
    correct the path and re-type.
  - Each successful expansion emits "[aish] @path expanded (N bytes
    [, truncated])" so the user sees what was inlined.

marfrit dccd9e90cc repl: :plan toggle — CMD: lines become PLAN: notes (closes #5)
Plan mode is a safer entry point than going straight to Norris: the user
iterates with the model on what to do, sees each CMD: as a PLAN: line,
and the would-have-run notes feed back into the next-turn context so the
model can refine without side effects.

Toggle with :plan (flip), :plan on, :plan off. Off by default.

When plan_mode is true:
  - CMD: lines extracted from the assistant turn print as "PLAN: <cmd>"
  - The note "[plan] would run: <cmd>" is appended via the existing
    append_exec_output channel — same context flow as a real exec, so
    the model sees its proposed action on the next turn.
  - run_shell is NOT called; no executor, no cd intercept, no capture.

The prompt shows "[aish:<model> plan]>" while active (mirrors the
norris  marker convention).

Orthogonal to Norris: plan_mode only gates the interactive CMD:
extraction path. Norris has its own halt protocol; combining them is
not supported (the planner would be confused by skipped actions).

marfrit 81c3b1b44a main: non-interactive -p/--prompt one-shot mode (closes #4)
Adds `aish -p "<text>"` for Unix-pipeline composability:

  tail app.log | aish -p "any anomalies?"
  aish -p "summarize: $(curl -sS https://...)"

The flag bypasses repl.lua entirely. On invocation:

  1. Stdin: when not a TTY, read to EOF and prepend to the prompt as a
     fenced block. ffi.libc.isatty(0) gates the read so interactive
     `aish -p "..."` (no pipe) doesn't hang.
  2. Resolve config.models[config.default_model].
  3. Stream broker.chat_stream replies to stdout; finalize with newline.
  4. Exit 0 on success, 1 on broker error, 2 on arg / config error.

Behavior NOT in -p mode (kept simple per the issue's "no repl.lua

marfrit 0700dce881 repl: enforce budget per Norris step, not just post-loop (closes #51)
PHASE3.md §2 specifies sliding-window eviction "including mid-Norris-
session if the loop runs long". Implementation only called
enforce_budget() once, after the planning loop exited — so for a tight
max_turns with a multi-step Norris session the model saw the FULL
conversation throughout, defeating context budgeting and preventing
R-C3 (NORRIS suffix goal anchor surviving eviction) from being
exercised end-to-end.

Move status_evictions(ctx:enforce_budget()) inside the while loop so
it runs after every safety.norris_step return. Drop the now-redundant
post-loop call.

Surfaced during TC #38 (Qwen3-30B-A3B, max_turns=4) where the
"oldest 4 turns evicted" status arrived AFTER NORRIS DONE.
